An integrated fuel control unit for gas-operated internal combustion engines that includes a base on which a primary diaphragm is secured to define a primary fuel chamber. A primary fuel orifice is carried by the base, as is a primary control lever that is coupled to the primary diaphragm for controlling flow of fuel through the primary orifice as a function of inlet fuel pressure and engine demand. A secondary diaphragm is also secured to the base to define a secondary fuel chamber. A secondary orifice is carried by the base between the primary and secondary chambers, and a secondary control lever is coupled to the secondary diaphragm for controlling flow of fuel through the secondary orifice as a function of engine demand. A heat exchange section in the body receives engine coolant or engine oil for heat exchange with fuel so as to heat and vaporize the fuel between the primary and secondary chambers. A high-pressure fuel lock-off is carried by the body, and includes a solenoid coil mounted on the body and a solenoid plunger within the coil for selectively closing an end of the primary orifice remote from the primary control lever.
A self-cleaning attachment for a rotary mower has a carrier member ( ) supporting a flexible, linear element ( ) radially spaced from the rotational axis of the blade at a level above the blade so the element rotates near the underside of the mower housing defining a narrow upper chamber where air pulses are concentrated to maintain the underside of the housing relatively clean of build-up. The carrier may have a plurality of elements in equally spaced relationship, the structure of which is such that the outer tips are supported above the blade when idle, and the inertial mass is low compared to the rotating mass of the blade such that there is relatively little rotational effect as the elements become worn. The attachment is retro-fittable to existing mowers without causing appreciable power loss or degrading the blade stopping capability below ANSI standards for residential lawn mowers.

Assignee:
Lonmore, LC - Means KY
International Classification:
B60K 28/16
US Classification:
180197, 180 632, 180 624, 280 911
Abstract:
A control system with slow-in-turn capabilities for use with a self-propelled, steerable vehicle, such as a lawn mower, is disclosed. In one embodiment, the system slows the vehicle speed when turns are made beyond a predetermined range and the speed is at or above a predetermined level, as determined by a speed control device operatively connected to the speed control structure of a motive device by a speed control linkage. This slowing results in increased traction for achieving tighter turns and also improves dynamic stability. Two different types of rack-and-pinion steering systems capable of being used with the control system are also disclosed.
Variable Flow Control Devices, Related Applications, And Related Methods
Devices for adjustably controlling a flow of fluid through a common passage and through first and second auxiliary passages are disclosed. The flow control devices may be used for controlling the steering of a vehicle having independently controlled driven structures, such as wheels. Various other applications of these devices and related methods are also disclosed.

International Classification:
B60Q 1/00
US Classification:
3404502, 340450, 340438
Abstract:
The low fuel warning system includes a fuel line configured to transport fuel between an inlet port and an outlet port and a reservoir located intermediate to the inlet port and the outlet port, wherein the reservoir is configured to collect the fuel in a liquid state. The low fuel warning system further includes a fuel sensor located adjacent the reservoir and configured to detect the liquid state of the fuel and a processor in communication with the fuel sensor. The processor is configured to monitor a low fuel condition in the fuel line according to information received from the fuel sensor.

US Classification:
124078000
Abstract:
A set of universal fit retaining plates which secure to one or more legs of a ball pitching or skeet throwing machine to help maintain a steady trajectory of the throwing mechanism. The plates are engaged to the ground with protruding devices and secure to the machine leg(s) by means such as a funnel type pocket which can hold the end of a leg in a wedge fit condition. This accommodates a variety of machines with different leg angles, leg end profiles, and leg end materials. The retaining plates help keep the throwing machine in a steady position in a variety of conditions and situations such as hard, dusty ball field surfaces, soft, moist field conditions or when a ball hits the machine.

A bicycle utility bracket to accommodate an auxiliary child seat and a towed bicycle that can be mounted on either rigid or suspension type bicycle frames. To accommodate a towed bicycle, the bicycle utility bracket device is positioned between a tow bicycle, such as an adult bicycle, and a towed bicycle, such as a child's bicycle, enabling the towed bicycle to function as a one wheeled trailer behind the leading tow bicycle. This or a variation of this same device can also accommodate an auxiliary child seat. The device can include pivoting structure provisions which can articulate with a suspension style bicycle frame as it articulates. This device can also provide a cushioned ride for an occupant in the child seat and a rider on the towed bike when used with a suspension type bicycle. It also includes provisions to quickly and conveniently attach or remove a towed bicycle which allows each bicycle to be operated independently as desired. When the towed bike or child seat is disconnected, the compact bicycle utility bracket device can conveniently remain on the tow bike.
