US Patent:

46118705, Sep 16, 1986

Filed:

Aug 13, 1984

Appl. No.:

6/639831

Inventors:

Howard L. Beers - Cape Coral FL

Assignee:

Tritec, Inc. - Naperville IL

International Classification:

H01R 909

US Classification:

339 75MP

Abstract:

An electrical connector for printed circuit boards having two or more rows of printed terminals along one edge of the board. When the board is inserted in the connector body, the contacts within the connector are prevented from making contact with any printed terminals on the circuit board until the board has reached its operative position within the connector and all the contacts are aligned with the printed terminals they are intended to make contact with. The contacts within the connector are carried by resiliently deformable supports. The working portion of the connector includes a series of four more elements (one of which is a locking means for automatically preventing operation of the actuator unless a printed circuit board is in place in its operative position within the connector body) each of which is affected by the next succeeding element in a defined way during the operation of the device.

Abstract:

A comparative temperature compensating specific gravity test apparatus is disclosed including an indicator float element that has a predetermined specific gravity and is freely suspended in a homogeneous test liquid. The float element includes pliable, sealed container that is substantially free of contained gas and a reference liquid that fills the container. The reference liquid has a thermal expansion characteristic which is substantially the same as that of the test liquid. The container has a mass which is negligible relative to the mass of the reference liquid. The float element is monitored in the test liquid such that floating of the float element indicates that the test liquid has at least the predetermined specific gravity and sinking of the float element indicates that the test liquid has less than the predetermined specific gravity.

International Classification:

US Classification:

Abstract:

An electrical connector for printed circuit boards having two or more rows of printed terminals along one edge of the board. When the board is inserted in the connector body, the contacts within the connector are prevented from making contact with any printed terminals on the circuit board until the board has reached its operative position within the connector and all the contacts are aligned with the printed terminals they are intended to make contact with. The contacts within the connector are carried by resiliently deformable supports. When the board is inserted in the connector it preferably imparts translational movement to a carriage on which actuators are mounted, and the actuators press the deformable supports and their contacts against their associated printed terminals on the printed circuit board. In this way, the board passes through four positions--safe, ready, initial contacting, and final operative positions--after it is inserted in the connector.

International Classification:

G01F 1114

US Classification:

222246

Abstract:

A single dosage substance dispenser is disclosed, which includes a housing having a chamber formed therein for holding a substance to be dispensed and a discharge port that communicates with the chamber. A plunger is slidably mounted to the housing for extending through the chamber and into the discharge port. The plunger includes a first seal portion proximate a lower end thereof, a second seal portion disposed above the first seal portion and a receptacle portion located between the first and second seal portions for accommodating a single dosage of the substance to be dispensed. The first and second seal portions are sealably and slidably engageable with the discharge port. A spring is provided for urging the plunger to retract so that the first seal portion engages the discharge port and the receptacle portion is maintained in the chamber to collect the single dosage therefrom. The spring also permits the plunger to be advanced so that the second seal portion engages the discharge port and the receptacle portion is driven beyond the discharge port to dispense the single dosage collected from the chamber.

International Classification:

G01N 2100

US Classification:

250565

Abstract:

An indicator circuit is provided for an apparatus that measures the concentration of a selected component in a test sample. The apparatus generates a test voltage that represents the concentration of the component in the test sample. The circuit generates a series of range voltages, each of which represents a respective one of a series of potential concentration ranges of the component in the test sample. A switching circuit selects an adjacent pair of range voltages immediately above and below the test voltage and applies the selected range voltages across an incremental voltage divider such that the voltage difference of the selected range voltages is divided into a series of incremental voltages, each of which represents a respective one of a series of potential incremental concentration levels of the component within each concentration range. The test voltages are compared with each of the incremental concentration voltages and the actual incremental concentration level of the component in the test sample is determined. There is a group of incremental indicator elements, each of which represents and displays a respective incremental concentration level in each of the concentration ranges.

Abstract:

A viscosity test apparatus is disclosed including a reference chamber that is partially filled by a predetermined volume of reference liquid having a known viscosity. There is a test chamber attached to the reference chamber which is partially filled with a test liquid having a volume and viscosity/temperature characteristic that are substantially similar to those of the reference liquid. An elongate first conducting column mounted within the reference chamber includes an open upper end that interconnects the reference chamber and the first column and a lower end having a first orifice that is submersible in the reference liquid for conducting the reference liquid under a pressure head between the first column and the reference chamber. A second column is mounted within the test chamber in substantial alignment with, and having dimensions substantially identical to the first column. The second column includes an open upper end and a lower end having a second orifice that is submersible in the test liquid for conducting the test liquid under a pressure head between the second column and the test chamber.

Abstract:

A turbidimeter including a sensor apparatus that has a housing with first and second receptacles. An incident light beam is established within the housing by a light source module that is releasably engaged with the first receptacle. A test liquid holder is removably engaged with the first receptacle. A test liquid holder is removably received by the second receptacle for positioning a liquid to be tested in the path of the incident beam. A photodetector or analogous instrument is provided at an angle to the incident light beam for sensing light scattered by the test liquid. An analyzer apparatus includes appropriate circuitry that is responsive to the photodetector for determining the turbidity of the test liquid. The turbidity is then displayed in both graphic and instantaneous alphanumeric form.
