The rollers are carried on a pair of radially reciprocable pistons mounted in a feed housing through which the wire is advanced, and a projecting rear portion of the housing has a threaded outer surface for receiving a force-adjusting nut.  A conical guide element is slidably mounted on the outer surface of the rear housing portion, and is urged against the adjusting nut by means of a calibrated spring.  A pair of symmetrically arranged two-arm levers entend longitudi-nally through a pair of slits in a flange integral with the housing intermediate its ends, with the rear end of the levers in contact with the conical guide member through a roller, and with the front ends of the levers maintained in abutting rela-tion with the outer ends of the pistons by means of springs. The shaft of a drive motor is fixedly connected to the rear portion of the housing.

Abstract: Abstract of the Disclosure A microwave oven is equipped with a rotary table for supporting the food material to be cooked.  The rotational center of the rotary table is positioned closer to the rear wall of the heating chamber than the door which forms the front wall.  The distance between the door and the rear wall is also larger than the internal width of the heating cavity.          This arrangement reduces the danger of electric wave leakage resulting from breakage of a shielding plate in a window in the door and its reinforcement due to contact of the food material or a spit located therein with such reinforcement and the resultant spark discharge.

Abstract: Abstract of the Disclosure At the sending end, each of a plurality of code signals generators furnishes a signal having a character-istic (e.g. frequency) different from the corresponding characteristic of the other code signals.  Timing signals derived from the television signal and signals from a random pulse generator are combined to furnish enabling signals for enabling the code signal generators during predetermined time intervals of the television signal and in random order.          A logic circuit which includes externally operable switches for setting up a program code assignment receives the en-abling signals and furnishes an encoder control signal only in response to certain selected enabling signals.  The encoder control signal changes the polarity of the picture signals relative to the synchronizing signals.  A mixer mixes the code signals into the encoded television signal. At the decoder the code signals are filtered out, and a logic circuit set up in accordance with a program code assignment corresponding to the program code assignment at the encoder furnishes a decoder control signal which causes a reversal of the polar-ity of the picture signals previously inverted by the encoder.          A predetermined pattern of the code signals, designed to cause a bistable circuit at the receiver to change state a predetermined number of times if the decoder is in the correct decoding mode, is periodically inserted into the transmitted encoded television signal. A counter counts the number of state changes and, if correct, a validation signal is furnished.  The validation signal allows record-ing of the billing charge for the program and transmission of the decoded signal to the television receiver.  Transients generated due to unavoidable timing and slope errors in the leading and trailing edges of pulses used to invert the picture signals are removed by clamping the television signal to a predetermined reference level for short time intervals around each desired switching instant. At the decoder, a clamping circuit clamps the television signal to ground potential during the clamping intervals, thereby balancing the DC components of the signal portions.                             -1'-

Abstract: A B S T R A C T          A cooling system for a gas turbine engine having a gasifier turbine and a power turbine each interconnected by a turbine casing utilizes compressed cooling air communicated to axial cavities in the ends of the respective turbine shafts.          This compressed air is directed outwardly between a flange integrally formed with the turbine shaft and the turbine wheel for communication to the turbine blades.  In the gasifier turbine the cooling air passes through longitudinal passages formed in each blade, while in the power turbine the cooling air is dis-charged adjacent the blade root.  Wheel flanges affixed on either side of the turbine wheel serve to retain the blades axially on the wheel.  Compressed cooling air is also communicated to the nozzle vanes of the gasifier turbine wherein internal passages communicate the air into the main gas stream.  Certain nozzle vanes are equipped with passage means to communicate air to an annular chamber surrounding the gasifier turbine.
