Abstract: ABSTRACT OF THE DISCLOSURE   A TV monitor includes an antenna coupler capable of selectively coupling the TV receiver being monitored to an antenna or an r.f. oscillator. The oscillator is selectively operated to impose an r.f. signal onto the antenna input of the receiver between successive horizontal blanking periods on an active video line.  One probe, connected to the horizontal retrace circuit of the receiver monitors the receiver for an "on" or "off" condition. A second probe, connected to the kinescope circuits of the receiver, detects the channel to which the receiver is tuned.  A third probe, connected to the vertical retrace circuitry, detects the vertical retrace signal to determine when the r.f. signal is to be imposed onto the receiver's antenna input.  By successively stepping the r.f. oscillator through successive frequencies within the bandwidth of individual channels, and by monitoring the kinescope probe for that frequency which compares to that generated, channel identification may be determined,  A plurality of individual monitors may be utilized with individual receivers within a household and the data may be collected and stored in a household collector for eventual transmission to a central station.

Abstract: ABSTRACT OF THE DISCLOSURE            Four or more cultivator arms or shanks are pivoted to the front and rear of a main frame and are interconnected by linkage so that if a cultivator blade on one arm strikes an obstruction, then it moves rearwardly to clear same and at the same time the others that are interconnected, move forwardly by a lesser amount thus absorbing the movement of the cultiva-tor blade striking the obstruction.  When the obstruction is passed, the engagement of the remaining blades with the ground, returns them to the original position thus returning the tripp-ed blade to the original position.

Abstract: Abstract of the Disclosure A key telephone adapter unit providing interconnection between a key telephone in-strument having a line selector unit with a plurality of lines and a corresponding plur-ality of line status indicators and an electronic telephone switching system in which audio frequency voice information signals and supervisorial serial data signals are interfaced to individual telephone hand-sets by first and second conductor pairs.    The adapter unit responds to a serial data polling command received from the switching system over the data part by converting signals representative of the status of each line of the associated key telephone instrument to serial data signals for transfer to the switching system over the data pair; and responds to other serial data commands received from the switching system over the data pair by generating command signals for directing operation of the line status indicators, e.g. the status lamps, the bell and the buzzer.

Abstract: ABSTRACT           A variable air flow oven is disclosed in which a var-iable air directing control means delivers varying amounts of heated air under various positive pressures in an alternating pattern to jet orifices in opposite side walls of the oven in an inverse ratio.  Hot air jets from opposite sides of the oven meet at points of common velocity in the processing chamber to produce a turbulent mixing of the hot air in a vertical plane.  The tur-bulent heated air travels form one side of the oven to the other at a constant rate under the controlled operation of a motor driven mechanical linkage arrangement to assure even baking, cooking or drying of the products being processed through the entire processing chamber in the oven.  The system operates at a positive pressure at all times, so that the main supply of heated air flows through one side duct and a smaller volume of heated air flows through the opposite side. As the static pressure is varied to the hot air jets in the opposite side walls, the ver-tical plane of turbulent heated air sweeps back and forth through the chamber, contacting the entire product, and then is drawn into a return duct for reheating and recirculation.

Abstract: ABSTRACT OF THE DISCLOSURE      The instant invention relates to a method of preparing an electrical contact from sub-micron size silver and less than two micron size cadmium oxide particles with the contact having finally dispersed particles of cadmium oxide within grains of silver.  In the instant invention the particles of silver and cadmium oxide are intimately blended together and subjected to a reducing atmosphere at a temperature of from 321°C to 550°C to reduce the cadmium oxide and form an alloy powder of cadmium and silver.  The alloy formed is held at an elevated temperature following reducing and then oxidized at a temperature of from 321°C to 550°C to precipitate a disper-sion of cadmium oxide within grains of silver and form a silver-cadmium oxide alloy powder.  In an alternative embodi-ment an alloy powder of cadmium and silver already prepared from sub-micron size particles of silver and less than two micron size particles of cadmium oxide is heated to a temp-erature of from 321°C to 550°C in an inert atmosphere.  The inert atmosphere is then changed to an oxidizing atmosphere at that temperature to precipitate the dispersion of cadmium oxide within the grains of silver.  The material as prepared by both embodiments is then formed into an electrical contact.

Abstract: ABSTRACT OF THE DISCLOSURE         A metering pump including a pump body having a bore for receiving a flowable composition to be dispensed, feed in-let means communicating with the bore, and spaced outlet means including a check valve, for discharging the composition.  A pressure chamber is defined intermediate the pump inlet and out-let.  The chamber has an inlet, and an outlet communicating with the pump outlet through the check valve.  A piston is mounted for axial reciprocation in the bore between a first position at which the piston is withdrawn from the pressure chamber inlet, and a second position at which the piston passes at least par-tially into such inlet.  The pressure chamber inlet is bounded by sealing means including an annular sealing surface which con-verges in the direction of the pressure chamber, to a diameter less than that of the piston, whereby the surface may slidingly engage and seal with the piston upon the latter entering the pressure chamber.  The sealing surface is elastically dilateable away from the axis of the bore, to maintain the seal about the piston during its entry and withdrawal from the pressure chamber and to enable compensation for wear.  At least one other surface of the sealing means is accessible to the pressure chamber in-terior, and is elastically coupled to the backside of the sealing surface.  In consequence, the increasing pressure developed by movement of the piston into the pressure chamber, acting through the accessible surface, increases the sealing forces between the sealing surface and piston.

Abstract: ABSTRACT OF THE DISCLOSURE              In a first embodiment, a control device includes a housing having a serpentinely disposed channel and a cover, secured to the housing, which converts the channel into an ultrasonic waveguide.  One end of the waveguide is bounded by a stationary reflector and the other end of the waveguide holds a piezoelectric transducer matched to the waveguide so as to provide therein, when actuated, a propagating transverse wave in the ultrasonic frequency range.  The cover includes a plurality of slots communicating with the waveguide, each slot being located at a different position along the propagation path of the waveguide; and a plurality of resiliently mounted reflectors, each reflector being associated with a different one of the slots and being insestable into the waveguide by, for example, fingertip pressure.  Actuation of the transducer by an electrical pulse causes an ultrasonic pulse to propagate down the waveguide.  The pulse is reflected back to the transducer, by the stationary reflector or an inserted reflector, where a delayed pulse is caused to appear.  The delay is related to the position  along the propagation path of the inserted reflector or the stationary reflector.  In a second and similar embodiment, a piezoelectric transducer is coupled to a resilient elongated waveguide, and selectable means are used to temporarily pinch the waveguide along its length.  The means selected determine the delay time of pulses transmitted and reflected back to the transducer.
