Filed:

Apr 3, 1978

Appl. No.:

5/892527

Inventors:

Marvin W. Shores - Pomona CA

Assignee:

General Dynamics Corporation - Pomona CA

International Classification:

H03D 300
H04B 106

US Classification:

325369

Abstract:

A system having a plurality of parallel tuned receiver channels, wherein a normalized phase relationship is maintained in the respective channels between amplified pulsed high frequency carrier signals having a given frequency is disclosed. Each of a plurality of parallel channels for receiving pulsed high frequency carrier signals from disparate sources includes a tuned frequency amplifier for amplifying a given frequency component of a signal in the channel within a predetermined bandwith. A continuous wave reference signal having the given frequency is inserted into each channel before the input of the tuned frequency amplifier. For each channel a phase comparator compares the phase of the reference signal components of the amplified signal with the phase of the reference signal; and a phase adjuster controlled by the phase comparator responds to the phase comparison by adjusting the phase of the signal that is provided to the amplifier. A separate switch is connected to each channel for providing the amplified signal to the phase comparator for that channel. A pulse detector and processor circuit receives the amplified signal from the plurality of channels and detects a coherent pulsed signal when such is present in any of the amplified signals received from the separate channels.

Appl. No.:

5/854434

Inventors:

Marvin W. Shores - Pomona CA

Assignee:

General Dynamics Corportation - Pomona CA

International Classification:

F42B 508

US Classification:

102 46

Abstract:

Apparatus for protecting the primers of electrically ignitable ammunition from accidental firing due to electrostatic charge build up and electromagnetic radiation. In one arrangement, the insulation between the primer cap and the metal case of the ammunition round is short-circuited with a conductive coating which covers the primer and base of the round. In a second arrangement, a conductive coating is used in the same fashion, but it is applied over a previously applied dot of non-conductive paint which covers a small area encompassing the primer and adjacent portion of the cartridge casing. Still another arrangement utilizes a circular metal foil affixed across the base of the casing with conductive cement that is applied only along the outer periphery. If desired, the metal foil may be supported on a protective layer of Mylar or the like.

Appl. No.:

6/112053

Inventors:

Marvin W. Shores - Pomona CA

Assignee:

General Dynamics, Pomona Division - Pomona CA

International Classification:

F24J 302

US Classification:

126438

Abstract:

A solar heat collector utilizing an elongated vertical mast to support a rectangular parabolic reflector and a transparent cover. The mast is located at the focal point of the parabolic reflector, and the fluid to be heated enters the unit at the bottom, is partially heated as it rises by convection, enters the mast at the upper portion thereof, and is transported downward while being further heated due to the mast focal point location. The unit is rotatable about the mast to maximize heat transfer.

International Classification:

G01J 500

US Classification:

374130

Abstract:

A dielectric heat sensor system for monitoring and measuring the effects of electromagnetic radiation on the performance or physical integrity of an electrical or electronic component includes a dielectric receiver in the form of a rectilinear array of fiber optic ends positioned to receive infrared heat waves from a bridgewire of an electro-explosive device and transmitting the infrared heat waves by way of a waveguide of electro optic fibers to an infrared detecting unit which is effective to activate an indicator.

Appl. No.:

6/594619

Inventors:

Marvin W. Shores - Pomona CA

Assignee:

General Dynamics, Pomona Division - Pomona CA

International Classification:

F42B 318

US Classification:

1022022

Abstract:

An improved electro-explosive squib device is disclosed with filter/shield characteristics rendering the device substantially immune to electromagnetic environments, thus preventing accidental ignition of the squib device. The invention provides for adapting existing squibs or constructing new squibs with immunity to the electromagnetic environments while adding only a minimal amount of material to the device, thus minimizing the possibility of personnel injury caused by debris ejected from rocket propellant ignited by the squib device. These benefits are achieved while maintaining reliability and extended shelf life, and at minimal cost of conversion or manufacture of the squib devices.

Appl. No.:

6/812597

Inventors:

Marvin W. Shores - Pomona CA

Assignee:

General Dynamics, Pomona Division - Pomona CA

International Classification:

F42C 1904

US Classification:

102293

Abstract:

An attachable, ablating shield comprises a metalized sheath for fitting closely over, for covering, and for protecting an electronics section in a missile from external electromagnetic radiation, particularly from high-energy radio frequency radiation, during launch. The sheath has weakened seams so that the sheath will separate from the missile when a seam is split. The sheath splitting system comprises an explosive device located near a seam, a detector for sensing the firing of the rocket motor, and a transfer line therebetween for receiving a motor-fire signal from the detector and for transferring a corresponding signal to the explosive device to split the sheath. A preferred embodiment employs a low-explosive and a transfer line that is a high-intensity shock pulse tube. The transfer line ablates with the sheath.

US Classification:

235 88R

Abstract:

An adjustable display having interworking parts whereby upon manipulation interference frequencies emitted from spurious harmonic and imaged electromagnetic radiators interfering with an intended or expected bracketed received frequency can be isolated and identified for later corrective action, such as elimination of the interference frequencies. A method for establishing emitted frequencies which might interfere with expected or intended targeted received frequencies in a receiver is also described and taught.

International Classification:

H01Q 150

US Classification:

343763

Abstract:

A flat slip ring which is larger in diameter than a conventional slip ring/brush assembly is attached to the rotatable unit concentric with and facing axially with respect to the shaft to carry the conventional slip ring/brush assembly. A circular brush is mounted on the housing of the slip ring/brush assembly concentric with the shaft and facing the flat slip ring. An electrically conductive spring urges the circular brush into contact with the flat slip ring and provides a low impedance ground from the rotatable unit to the housing of the slip ring/brush assembly.
