Abstract: Abstract In a system in which alternate lines of one color television video signal normally  are delayed half the period of the color subcarrier at a transmitting terminal to minimize the cross modulation of the color subcarrier with the color subcarrier of another video signal amplified in a common amplifier such as in a satellite transponder, an intermediate line delay unit at the receiving terminal is normally operative to delay intermediate lines of the one video signal half the period of the color subcarrier, and is automatically inhibited from delaying intermediate lines of the one video signal when the received alternate lines of said one video signal are for any reasons not delayed at the transmitting terminal.

Abstract: A SYSTEM FOR COOLING MOTOR BEARINGS                     ABSTRACT OF THE DISCLOSURE           A system for cooling the bearings supporting the shaft of a rotor in a motor.  The rotor responds to the flow of hot fluid under pressure by moving to develop an output signal.  The rotors which conduct heat from the hot fluid through the shaft and into the bearings have a series of peripheral axial slots adjacent the ends of the shaft.  Fasteners engage the shaft to position the bearings over the series of axial slots.  A manifold connects the slots to a discharge conduit.  Some of the hot pressurized fluid is diverted through a nozzle in the discharge conduit to create a pressure differential between the manifold and the surrounding environment.  This pressure differential draws air from the surrounding environment through the slots and into the manifold.  The air on flowing through the slots absorbs heat from the shaft and the inside of the bearings to thereafter maintain the temperature of the bearing below the hot fluid.

Abstract: OPEN TOP MULTIBAND REFRIGERATED DISPLAY CASE                   ABSTRACT OF THE DISCLOSURE           An open top refrigerated display case having mechanisms for establishing an inner refrigerated air band encircling the display portion of the case and an outer air band also encircling the display portion and being positioned outside of the inner air band.  An inner air conduit passes around the side and bottom walls of the cabinet of the display case and has an outlet opening at one end of the opening in the top of the cabinet and an inlet opening at the other end of the top opening in the cabinet.  A fan circulates air through this inner air conduit with the air leaving the oulet opening and being directed toward and received by the inlet opening of the conduit, thereby establishing an inner air band along with an inner air curtain across the opening in the top of the cabinet.  An evaporator coil arranged within the inner air conduit serves to refrigerate the air passing along the inner air band during a refrigeration cycle of operation.  An outer air conduit surrounds the inner air conduit within the cabinet and during a refrigeration cycle carries air which is cooler than ambient air, but unrefrigerated.  A second fan is provided within this outer air conduit for circulating air through the conduit and establishing an outer air band and outer air curtain across the opening in the top of the cabinet.  During a defrost cycle of operation, the evaporator coil is turned off and the direction of air flow through at least one of the inner or outer air conduits is reversed and unrefrigerated air is caused to pass through the inner air conduit, thereby serving to defrost that conduit.

Abstract: ABSTRACT OF THE DISCLOSURE        An apparatus for personal hygiene which includes a reservoir for containing liquid to be applied to selected parts of the body is provided with a dispenser containing a dentifrice to be dispensed therefrom upon demand. The dispenser is adapted to be housed in the bottom part of the casing of the apparatus. The dispenser is provided with a dentifrice container closed at the bottom by a flexible membrane and with an intermediate wall located above this membrane defining upper and lower container compartments. The intermediate wall includes an opening which permits communication between the two compartments. A closure finger attached to the membrane opposite the opening in the intermediate wall is adapted to be shifted between positions at which it is spaced from the open-ing and also disposed within the opening. In this manner, pressure applied to the membrane causes the closure finger to enter the open-ing and permits a measured quantity of the dentifrice to be taken off from the lower compartment. This pressure applying means includes a lever pivoted to the bottom of the apparatus casing below the dispen-ser. Tube take-off means conveniently directs the dentifrice from the lower compartment into the apparatus liquid containing reservoir. Biasing means serves to return the membrane to a position at which the finger is extended away from the opening. In addition, air venting means are provided to permit air to enter the contained to replace the dentifrice removed therefrom.

Abstract: ADAPTIVE AIR/FUEL RATIO CONTROLLER   FOR INTERNAL COMBUSTION ENGINE            Abstract of the Disclosure:           An air/fuel ratio controller for an internal combustion engine including a memory having numbers stored at locations addressed by engine operating points with the locations addressed by the engine operating points being updated during closed loop operation in accord with the value of a closed loop adjustment of the air/fuel ratio.  Each memory location in the memory is updated during operation of the engine at the corresponding operating point in accord with an update time constant having a value so that the number stored tracks adjustment value producing the predeter-mined desired closed loop air/fuel ratio during vary-ing values of engine temperature.  The update time constant is varied directly with the value of engine temperature so that the rate of adjustment of the numbers in the memory is greater during engine warmup where engine temperature increases rapidly.  The memory is used during closed loop operation to preset the closed loop adjustment at least when the engine first operates at an operating point.
