Filed: 1938-11-22
Abstract: 509,225. Magnets. BING, J., and BLOCK, O. Nov. 22, 1938, No. 33910. Convention date, Dec. 8, 1937. [Class 35] A lifting magnet comprises one or more units each consisting of a rotatable permanent magnet embraced by stationary polepieces having cylindrical faces concentric with the magnet, the polepieces completing the magnetic circuit. In the form shown, the magnets Ma, Mb, Mc, Md are linked together and are in the positions in which flux passes through the corresponding polepieces Pa<1>, Pa<2>, &c. and the load L. When the load is to be released, the magnets are turned through a right angle so that the polepieces serve as flux shunts. In the form shown in Fig. 6, each magnet M is built up of discs on a spindle and the spindles are linked together to permit angular movement of the magnets. If desired, a single magnet only may be used and the magnet may consist of powdered material in a container. The polepiece surfaces may serve as journals for the magnet, thus rendering a spindle superfluous. If desired, the magnets may be moved through an angle greater than a right angle to reverse the flux through the load.

Filed: 1970-07-15
Abstract: 1318575 Thawing frozen food FOSTER REFIGERATOR CORP 15 July 1970 [15 July 1969] 34379/70 Heading A2D [Also in Division A4]  A method of cooking food comprises subjecting the food to predetermined timed pulses of infra red radiation while maintaining around the food an air temperature controlled between the temperature at which the food is fully cooked and below the temperature at which exposed surfaces would be overcooked, for a first interval of time, and then reducing the air temperature around the food to a lower value for a second interval of time while continuing to subject the food to said pulses of infra red radiation. The food may intially be in the frozen state. The ambient temperature may be achieved by the use of a flow of cooled air, which air removes an amount of heat from the surface of the heated food to prevent charring thereof. The method may be carried out in an apparatus of the type shown in the figure wherein frozen food 42 is subjected to infra red radiation from heat sources 34 whilst an ambient temperature is maintained by the use of refrigerated air which is pumped around the interior of the unit 10 from the evaporator 22. Temperature sensors 52 and 58 are connected to a control unit which controls both the frequency and intensity of the infra red radiation and the degree of refrigeration. The method is applicable to the treatment of meat, pastry and bread.

Filed: 1936-12-21
Abstract: 479,554. Automatic exchange systems. BRASHER, W. ls. Dec. 21, 1936, No. 35007. [Class 40 (iv)] In a system in which a trunk operator establishes a checking circuit back to a calling subscriber over a second path, alternating current of super-audible frequency is employed for the checking signal. In the system shown, the operator having been called over a trunkdemand circuit establishes over a plug CP and a trunk-offering distributer and final selector, a second circuit back to the number given. Operation of key TT applies current of super-audible frequency from a valve oscillator OSC to the second path and also over a pad PD to a pentode amplifying valve PT to operate a relay A. Relay A operates relay B which lights lamp L and switches over the pentode input to the calling path so that if the calling member has been given correctly, the return of the superaudible current maintains lamp L lit steadily. If the number has been given incorrectly, relays A and B energize and de-energize successively and lamp L is flashed. If the oscillator or valve PT is faulty, the lamp is unlit. The checking frequency may alternatively be applied to the calling path and received back over the second path and may be applied to one wire only of the loop. One valve PT may he common to all the cords at an operator's position and one oscillator common to a number of operators.
