Title: Exhaust emissions control in gaseous fuelled engines
Inventor: BEDFORD TIMOTHY J
IPC: F02D11/08
Filed: 1991-04-22
Abstract: A fuel supply control for an internal combustion engine designed to run on gaseous fuel (LPG or CNG) utilizes a feddback loop from a lambda sensor in the exhaust gases to a moving coil (82) mounted on a diaphragm (34) of a diaphragm-actuated valve (24) controlling the flow of gaseous fuel to the engine. The coil (82) is similar to the speaker coil of an audio speaker, and moves concentrically of a fixed permanent ring magnet (86) to impart a variable bias on the diaphragm (34) in accordance with the oxygen content of the exhaust gas stream as sensed by the lambda sensor, to control the fuel or air-and-fuel supply to the engine in accordance with desired engine operating parameters. The control has a sufficiently rapid and positive response that it can maintain the free oxygen content in the exhaust gases at substantially 2 % for continuous operation of a catalytic exhaust purifier at or nearly at optimum efficiency.

IPC: B65G23/42
Filed: 1993-04-08
Abstract: A ratchet driven continuous chain accumulator conveyor and a accumulating and retrieval system utilizing such conveyor is shown. The accumulator conveyor includes a frame having a pair of continuous chains. The chains are mounted on sprockets on either end of the accumulating conveyors and run in upper and lower chain channels. A hydraulic drive cylinder is supported by the frame of each accumulating conveyor and includes gravity dogs on an operable piston end thereof. The gravity dogs provide for imparting a ratcheting motion to each pair of chains through extension and retraction of the drive cylinder. Each accumulating conveyor includes a plurality of lift means along the length thereof for lifting cases from contact with the driving chains for relieving weight pressure thereon. The accumulating and retrieval includes a computer control and loading mechanisms for automatically loading the accumulator conveyors with product. Some of the accumulating conveyors include automatic discharge means at their discharge ends and the remainder of the accumulating conveyors do not have such automatic mechanisms and are unloaded manually. The conveyors having automatic discharge ends include a further cylinder for pushing individual stacks of product onto an out-feed conveyor running directly adjacent and perpendicular to the out-feed ends of theaccumulating conveyors. A second out-feed conveyor is spaced from the first out-feed conveyor and runs parallel thereto. The second out-feed conveyor is used for conveying individual cases that have been manually transferred from the manual accumulating conveyors thereto. In this manner, specialty orders of lower volume product can be specifically selected and placed on the second out-feed conveyor. The first out-feed conveyor transports the stacks of cases to an appropriate loading dock area having means for assembling the stacks of cases onto a dolly for facilitating loading onto a truck. The second out-feed conveyor first passes through a stacking machine for stacking the individual cases to a desired height. From the stacking machine, the stacked cases then are directed by conveyor means to a loading dock area for assembly onto a dolly.

Title: Fiberglass cloth resin tape insulation
Inventor: WEINBERG MARTIN J
IPC: H01B3/08
Filed: 1993-05-03
Abstract: An improved electrical insulation tape is formed from a sheet of fiberglass cloth having a layer of thermoplastic resin bonded thereto. The thermoplastic resin layer is applied to the fiberglass sheet by melting the resin while contacting the fiberglass, and then the composite is cooled to bond the two components together. The composite sheet is then slit into tapes with substantially no unraveling of the fiberglass component at the slit edges of the tapes. The resultant tapes are easily wrapped on, and adhered to, conductors, such as magnet wire, or the like, by remelting and resolidifying thethermoplastic layer. The tape possesses excellent dielectric properties and heatdissipation properties. Alternatively, the fiberglass sheet may be impregnated with the melted thermoplastic component whereby a composite, rather than a relatively definitive two layer laminate, is formed.

Filed: 1993-06-01
Abstract: A mechanism for controlling method invocation and avoiding problems such as premature method execution before object construction and premature object destruction before method completion, is provided through a protocol function table in a class library. For any virtual functions declared in a class library, the thread of control invoking the function is re-directed through the protocol function table where it is either selectively accepted or delayed for later acceptance pending completion of some related procedure. When used in conjunction with an automatic routine for locating the originating point in an operating program, the protocol function table is particularly useful for executing concurrency in object-oriented applications.

Title: Two-frequency transmitting apparatus with tone-modulation phasing for an instrument landing system
Inventor: GREVING GERHARD
IPC: G01S1/14
Filed: 1993-06-08
Abstract: Abstract Two-Frequency Transmitting Apparatus with Tone-Modulation Phasing for an Instrument Landing System Two-frequency transmitting apparatus (S1, S2, LA) for instrument-landing systems is disclosed which is in-sensitive to DDM (difference in depth of modulation) distortions caused by reflections of the clearance sig-nal from obstacles (H) located near the runway (RW). This insensitivity is achieved by providing different phase shifts of the equal modulation frequencies (90 Hz and 150 Hz) used for the course and clearance signals. The different phase shifts correspond to a phase shift of a common fundamental frequency (30 Hz). The two-frequency transmitting apparatus can be used to specify a localizer course or a glide path.            Fig. 1
