Abstract: A cyclic crimping mechanism for producing coherent plural-layer food products from food assemblies, each food assembly including a bottom patty covered by a top patty (other patties, food slices, or condiments are usually positioned between the top and bottom patties), uses a cyclically, intermittently actuated conveyor to locate each food assembly at a crimping position for a predetermined crimping interval; in sequence, a confinement tool is moved down to an actuated position to define peripheral limits for the food product, a tamping tool is pressed down onto the food assembly to reduce air entrapment, and a crimping tool presses the periphery of the top patty into the bottom patty to seal them together in a coherent food product, after which these tools are all elevated to rest positions clear of the crimping position and the conveyor operates to move the finished food product away and position a new food assembly at the crimping position to start the crimping cycle anew.
Abstract: A limited slip differential for limiting differential rotation between a differential casing and axles via a frictional connection includes a pinion shaft rotating integrally with the differential casing and a pinion gear attached rotatively to the pinion shaft. A side gear engages with the pinion gear and is mounted loosely with respect to the axles. A first cam portion formed on the side gear engages with a second cam portion formed on a driving member which is spline-engaged with one of the axles, supporting the side gear and supported by and centered on the differential casing. A frictionally connecting clutch is disposed between the driving member and the differential casing.
Abstract: An improved outlet gate pan gasket is located between the outlet gate and outlet flange of a hopper car. The gasket includes a central web which fits around the perimeter of the outlet aperture. An inner margin is attached to the inner periphery of the web and an outer margin is attached to the outer periphery. The inner margin has upper and lower horizontal surfaces joined by an edge surface which is perpendicular to the horizontal surfaces prior to compression of the gasket between the gate and outlet flanges. The inner margin has a solid cross-section. The uncompressed thickness of the inner margin is greater than that of either the web or outer margin.
Abstract: A monitoring circuit for a battery charger, with utility in other applications, includes a main input that receives an initial signal such as the terminal voltage of a battery being charged, and a two-stage comparator, each stage preferably an operational amplifier. The initial signal is applied to the inverting input of the first stage, which is a differencing amplifier that also serves as a gain block; the initial signal is also delayed a brief interval, typically more than a second, and then applied to the non-inverting input of the first stage of the comparator. The inverting input of the second stage of the comparator receives the same signal as the non-inverting input to the first stage, whereas the non-inverting input to the second stage is derived from the output of the first stage.
Abstract: A motion and position control for use in a system that includes a motor or other prime mover for moving a tool or other device and a sensor that generates a signal representative of the position of the device; the control comprises a sensor signal processor circuit producing a sequence of pulse position count signals. Each pulse position count signal, which identifies the position of the device at a given instant, is recorded in an up-down counter circuit that operates conjointly with a CPU to generate a sequence of command signals, at a given sequence frequency, that are applied to the prime mover. Each command signal is determined by the difference between the desired pulse position value and the current pulse position signal, plus a drift factor representative of system inertia, and the last previous command signal, all divided by two. The control is applicable to a wide variety of motors and other prime movers in almost any kind of controlled movement system.

Each adjustable linkage is pivotally attached to a first member in mounting the auxiliary handlebar to the bicycle handlebar.
Abstract: A fabricated housing assembly for a faucet valve is made from multiple economically manufactured components which can be permanently attached by soldering or by an adhesively secured threaded connection.
Abstract: An automatic hand dryer contains a heating element and a motor which drives a squirrel cage fan. The fan exhausts air past the heating element to a downwardly-directed outlet. A base or mounting plate is adapted for flush mounting to a wall. The axis of the fan is peripendicular to the base plate and wall to which the dryer is attached. A control or sensing circuit emits signals to a detection zone beneath the outlet and monitors the zone for reflected signals indicative of a user's presence. The circuit operates to energize and deenergize the power circuit to the fan motor and heating element. Upon detection for a predetermined period, the circuit energizes the power circuit. The control circuit deenergizes the power circuit upon interruption of the reflected signals for a predetermined period, or after a predetermined maxium time period of continuous detection. Under the latter condition, the stimulus reflecting the emitted signals must be removed from the detection zone to reactivate the control circuitry.
Abstract: A plaster ground for a wall mounted faucet valve housing includes a body portion with a central opening for the valve housing and a cylindrical portion releasably attached to the body portion and extending about the valve housing. A pair of flexible retaining arms integral with the body portion are adapted to engage and secure the plaster ground to the valve housing.

Abstract: A multi-frequency shunt is provided for use between the rails of a railroad track to define the approach distance for a railroad crossing using a constant warning time or motion detection device. The shunt includes a housing with a PC board having rail terminals thereon being mounted in the housing. There are connections from the rail terminals of the PC board, extending outwardly through the housing, to the rails. The PC board includes a plurality of inductive and capacitive elements mounted thereon and connected to header terminals which are mounted on a header board. There are straps for interconnecting the header terminals with the interconnections between the header terminals determining which inductive and capacitive elements are connected between the rails and thus determining the nominal frequency of the shunt.
