Abstract: DEEP FAT FRYER HAVING A SOLID-STATE CONTROL CIRCUIT                 ABSTRACT     A solid-state control circuit for selectively operating a deep fat fryer in a normal cook mode, a lower temperature hold mode, a fat melt mode and a safety thermostat test mode.          During operation in the cook mode, a reference bias voltage is coupled to one input of a voltage comparator, and an operating bias voltage dependent on the temperature control setting and the actual cooking fat temperature sensed by a NTC resistive sensor is coupled to a second input of the comparator such that the comparator is effective to enable heating elements in the  cooking fat when the  fat  temperature drops below the preset level.   After a predetermined time interval during which the fryer is not being used, a timing circuit acts to vary the reference bias voltage and the operating bias voltage supplied to the comparator and thereby reduce the temperature of the fat to the lower preset hold mode temperature.  A second comparator resets the timing circuit during the predetermined time interval if there is a demand for heat such as when frozen foodstuffs are placed in the cooking fat.  In the melt mode, the timing circuit controls the first comparator such that the heating elements are cycled on and off to melt solidified cooking fat without scorching,  and  in the test mode,  the temperature control potentiometer is bypassed to cause the first comparator to enable the heating elements to safely heat the cooking fat to a temperature where the safety thermostat and the safety contactor should function.

Abstract: ARC DISCHARGE LAMP UNIT HAVING AN INCANDESCENT SERIES FILAMENT BALLAST                   ABSTRACT OF THE DISCLOSURE A lighting unit is described utilizing an energy efficient metal vapor arc lamp as the main source of light supplemented by a standby filament-ary light source producing light when the arc lamp is being started, the filament thereof serving as a resistive ballast for the arc lamp under normal operation.  The lighting unit is designed as a more efficient replacement for the incandescent lamp. The lighting unit includes a rectifier for conversion of 60 hertz ac to dc, and a dc energized operating network, including a ferrite transformer and a trans-istor switch.  The operating network produces an outpost adapted to each operating state of the arc lamp, including the provision of a high ignition potential, a power boost for the lamp during the glow to arc transition, warm-up and ballasting provisions, and means for sustaining the arc during transients which reduce the line voltage.  The filamentary light source provides useful standby illumination while the arc lamp is being started, the amount being reduced to a low value as the arc lamp approaches normal light outpost.

Abstract: Abstract Warm food products are chilled to a sanitary storage temperature approaching 0°C without dehydration by intro-ducing them into a cold humid 100% humidity chamber.  The humidity is regenerated by spraying refrigerated water and the products are passed through a chilling chamber on a conveyor belt with a spiral path configuration. Various cabinet features reduce input energy and provide sanitary conditions, such as supplying sanitary water, and filtering droplets of water from the cold moist air to avoid contamination of product disfiguring drip. Provisions are made to prevent a moving conveyor belt from carrying warm air into the chiller or from carrying cold air out of it as it passes continuously through the chiller cabinet.  All lubricated mechanical equipment is mounted external to the food processing chilling chamber and access doors are provided for sanitation.  The water spray chamber and water flow paths are simply sanitized by replacing the water with a detergent solution.

Abstract: IMPACT WRENCH MECHANISM AND CLUTCH THEREFOR         ABSTRACT OF THE INVENTION This invention pertains to an impact wrench mechanism and a clutch therefor, wherein a motor having an output shaft rotatably drives carrier member means mounted on an axis.  Anvil jaw means ro-tatably and coaxially mounted adjacent the carrier member means have impact jaw means extending radially therefrom.  Hammer member means having impact jaw means for impacting with the anvil jaw means is mounted on the carrier member means for rotation therewith and for limited linear motion relative thereto in a direction essentially transverse to the axis of rotation to allow the hammer member impact jaw means to contact the anvil jaw means.  The line of force of the impact blow has a force component tending to urge the hammer means out of engagement with the anvil jaw means, but the hammer means has a mass and a mass center location such that linear inertial force is created which prevents motion of the hammer member means during the impact blow.

Abstract: MASTER CYLINDER AND PROPORTIONING VALVE THEREFOR  ABSTRACT OF THE DISCLOSURE A master cylinder provides a housing defining a reservoir and movably carrying a pair of pistons within a bore in communication with the reservoir.  The pair of pistons cooperate with the housing to substantially define a pair of pressure chambers which communicate with respective brake circuits.  One of the pistons forms a cavity to receive a reaction piston and the one piston also carries a proportion-ing valve.  The reaction piston forms an auxiliary chamber within the one piston and the proportioning valve is exposed to the auxiliary chamber.  The reaction piston extends outwardly into one of the pres-sure chambers to engage the housing and the valve member is respon-sive to the fluid pressure in the other pressure chamber to control fluid communication between the auxiliary chamber and the reservoir. When the valve member closes the auxiliary chamber during a brake application the movement of the one piston relative to the reaction piston increases fluid pressure in the auxiliary chamber to oppose movement of the one piston.  Therefore, the increase of fluid pres-sure within the one pressure chamber is restricted so as to pro-portion fluid communication from the one pressure chamber.

Abstract: ABSTRACT In the bending of strips or skelps of different widths into split tubes or pipes which are subsequently closed and welded to form completed pipes of correspondingly varying diameters, the bending is done in a series of progressive bending stages constituting a set.  Each stage provides a particular degree of bending.  For a strip of a particular width, only a selected group of the avail-able set of bending stages is used. The set of stages available may include a little less than twice the number of stages used in any group, the number of stages in each group being always the same.  The set of stages includes one for providing the smallest curvature and a last one for providing the largest curvature.  These stages are never used together.  The first one serves as the first stage in a group selected for bending the widest strip, and the last one will be used as the last stage in the group selected for completing the smallest diameter tube.  Each stage is formed by a plate which has a slot outlining the curvature to be imparted by that stage, bending rollers being journalled along the slot on both sides of the plate.  The selected set of plates for a given bending operation are arranged in series within a frame, and are readily remov-able and replaceeable when a bending operation on a different width strip is to be performed.
