Abstract: A Torque Tool Calibrating Machine comprising an elongate torque tool engaging transducer including a strain gauge and mounted on a turning axis; an electronic analyzer connected with the gauge and operating to analyze, translate and display the voltage drop across it in torque force units and to emit a control voltage when it operates to display a predetermined maximum units of force, a manually driven gear transmission to turn the transducer including drive and driven gear wheels, a turntable supported on said turning axis and coupled with the transducer, an elongate lever arm projecting radially from the turntable and drivingly coupled with the transmission to selectively rotate the arm, table and transducer clockwise and counterclockwise, and a locking mechanism selectively operable to lock one of the gears against clockwise or counterclockwise rotation and including solenoid-acutated latch units with pawls that engage the gear when the solenoids are energized; a controller circuit connected between the an

Abstract: A ball and socket-type Universal joint including an elongate female part with an elongate, central, polygonal socket opening entering one end and defining a flat axially disposed bottom and a plurality of elongate circumferentially spaced, radially inwardly disposed, longitudinally straight and laterally convex flats; an elongate male part with a shank and a semi-spherical polygonal head at one end of the shank and having a plurality of elongate circumferentially spaced, radially outwardly disposed, longitudinally extending, laterally straight and convexly curved facets. The head of the male part is engaged in the socket opening of the female part with opposing points on the flats and facets, along the central portions thereof, in circumferential driving and longitudinal sliding bearing engagement with each other. The other end of the female part is connected with an end of one elongate rotatable work piece, and the other end of the male part is connected with an end of another elongate work piece.

Abstract: An improved elongate drain trap made of a material having a low index of heat conductivity and having inlet and outlet end portions and a substantially U-shaped central basin portion below and extending between the end portions and in which water is contained and sometime freezes to establish an ice plug; the improvement comprises an elongate insert made of material having a high index of heat conductivity and having an upper end portion in the inlet portion of the trap and a lower end portion extending through the central basin portion of the trap. The insert functions to absorb heat from hot water deposited in the inlet portion of the trap and to conduct that heat through the basin portion of the trap where it melts a sufficient portion of an ice plug formed therein to establish a flow passage for water through the plug.

Abstract: A beverage making and dispensing apparatus comprising a pressurized water supply; a non-pressurized beverage syrup supply; a hydraulically driven proportional pump with water and syrup inlets connected with the water and syrup supplies, water and syrup outlets connected with a water delivery line and a syrup delivery hose; an aspirator-atomizer mixing device with an elongate mixing chamber with an outlet end, a water passage with an inlet end connected with the water delivery line and a nozzle end to direct a jet of water longitudinally of the chamber toward its outlet end, a syrup port communicating with the chamber and connected with the hose; a water valve to start and stop the flow of water from the pump into and through the mixing device; and, a flow control device in the hose downstream of the pump and upstream of the syrup port to establish a pressure drop and maintain a positive pressure at the syrup outlet of the pump that is less than the minus pressure at the syrup port and a pressure at the syrup

Abstract: A controller for a centrifugal clutch with circumferentially spaced actuating weights having radially inwardly projecting actuating arms that pivot rearwardly as the rate of rotation of the clutch accelerates and the weights move to increase actuating pressure in and through the clutch. The controller includes a fluid actuated cylinder and piston unit with a piston rod that carries an arm engages throw-out bearing positioned rearward of the actuating arms. The cylinder is normally charged with a fluid medium that urges the piston and rod forwardly to one end of the cylinder and where the throw-out bearing engages and stops the arms in their normal unactuated position.

Abstract: The Torque Transducer structure comprising a lower base plate, and an elongate torque member projecting vertically upwardly from the plate. The member has rigid upper and lower end portions and a central deflection portion that is rigid through a first radial plane through the structure and is flexible through a second radial plane of the structure which is at right angle to the first radial plane. The central portion of the member carries strain gauges and is torsionally deflected by torsional forces directed onto the upper end portion of the member. The member is subject to adverse lateral deflection through the second radial plane of the structure by lateral forces directed onto its upper end portion. The lower end portion of the member is coupled with the plate against rotation and for free pivotal movement relative thereto through said second radial plane of the structure.

Abstract: The method for filling a soft, flexible, thin-walled inflatable bladder with a fluid medium to a predetermined extent that comprises; folding a portion of the soft, flexible, thin-wall of the bladder and engaging the fold in predetermined pressure engagement between opposing clamping surfaces of a clamping device and thereafter introducing fluid medium into the bladder to fill it. The fold slides from engagement between the surfaces when the tensile forces directed onto and through the wall by the fluid medium delivered into the bladder exceed the holding force exerted by the clamping device.

Abstract: The pay phone apparatus of this invention includes a multiplicity of pay phones; a central switching board including a central switching device for each pay phone; and, a pair of telephone lines connecting each pay phone and its related switching device. Each pay phone has a coin mechanism to receive and hold nickels, dimes, and quarters deposited therein. The mechanism sends nickel, dime, and quarter coin signals to its related switching device each time a nickel, dime or quarter is deposited therein and operates to return coins held thereby to the user of the pay phone or to deliver them into a coin box in the pay phone in response to coin return and coin accept signals directed to it from the switching device.

Abstract: A prenatal body support upon which a pregnant woman lies, face down, and that functions to remove the weight and pressure of a fetus within her abdomen from within her pelvic cavity and adjacent her spine and that relieves stresses imposed on her pelvis and spine caused by the weight and size of the fetus. The support comprises a soft, compressible and resilient body with front and rear ends, laterally spaced sides, a bottom surface and a top body supporting surface.

Abstract: A refrigeration unit for coin-operated, food item vending machines having box-like metal cabinets with substantially flat, vertical front panels; substantially flat, horizontal top panels; coin mechanisms within the cabinets; food item supporting, transporting and dispensing mechanisms within the cabinets; item selecting and operating mechanisms; and, item discharge ducts extending through and accessible at the exterior of said front panels. The refrigeration unit operates to recirculate and cool the air within the cabinets and to maintain food items therein at desired, safe, low temperatures. The refrigeration unit includes a horizontal, downwardly opening box-like base supported atop the top panel of a related machine with said top panel closing the bottom thereof. The base has a vertical partition extending transverse its interior and defining a downwardly opening air delivery chamber and a downwardly opening air return chamber.
