Title: Improvements in meat slicing machines
IPC: B26D1/143
Filed: 1937-12-28
Abstract: 500,457. Slicing-machines. REVOUY, H. Dec. 28, 1937, No. 35898. Convention date, Dee. 29, 1936. [Clasa 28 (ii)] A machine for slicing joints of meat having substantially central bones, such as hams, comprises a plate 17 carrying a rod 16 which is passed into the previously drilled bone of the ham, the plate being mounted for rotation on an axis coincident with the rod 16, and for reciprocation along tracks 27 towards and away from a knife 1, which may be a stationary knife or a band knife, but. as shown, is a disc knife-driven by a belt 6 from a motor 2. The plate 17 is supported on an internally threaded ring 19 screwed on to posts 20, the ring being rotated in any appropriate manner to effect vertical slice-feed movements of the plate 17. The posts are screwed into a turntable 21 supported on rollers 24, the central shaft 22 having, at its lower end, a wheel 33 which contacts with a roller 34 when the meat is moved against the knife and the knife is about to contact with the bone. The roller 34 is driven by a belt 36 from the motor 2 and is mounted on an arm 39 which is pulled by a spring to keep the pinion 34 against the wheel 33 whereby the latter is frictionally driven to rotate the meat and complete the cutting of the slice. The carriage 25 is mounted on rollers 26 and is reciprocated by a handle 29 which is pivoted at 30 and urged away from the carriage by a spring 32, so that the handle moves against the action of the spring when the knife contacts with the bone. The slices are deflected away from the knife by a deflector 45. The knife may be arranged to reciprocate towards and away from the rotating joint.

Title: Improvements in or relating to wireless and like receivers
IPC: H03J7/04
Filed: 1934-12-14
Abstract: 449,391. Valve circuits for wireless reception. SPENCER, R. E., 8, Courtfield Gardens, Ealing, London. Dec. 14, 1934, No. 35959. [Class 40 (v)] A wireless receiver is automatically pulled into exact tune by causing the departure from tune to control. the bias on the outer grid of a hexode valve 32 functioning as a variable impedance, the reflected capacity in the control grid circuit varying the frequency-determining circuit 4 of the heptode frequency-changer 1 of a superheterodyne receiver. The output circuit of the intermediate-frequency amplifier 15 comprises a series circuit 19, 20 tuned to the intermediate frequency, the voltage across the condenser 20 being applied to a diode 23, 24, while that across inductance 21, coupled to 19, is applied to the diode 26, 24. The arrangement is such that when the receiver is exactly tuned, the two voltages are equal, and since the load resistances 27, 28 of the two diodes are connected in opposition there is then no p.d. between points A and A<1>; the bias of the outer grid of 32 is then determined by the resistance 34. If the receiver is detuned on one side or the other of the true I.F., the voltage across 21 or 20 predominates and the bias of the outer grid of 32 increases or decreases, the resulting change in input - circuit capacity varying the local oscillator circuit of 1 in compensating sense. The input capacity of 32 may be augmented by a small variable condenser 36 which may be unicontrolled with the receiver tuning to make the control even over the entire tuning range ; alternatively, the resistance 33 may be variable and may also be conjointly operated with the tuning for the same purpose ; or the condenser 36 or resistance 33 may be replaced by a number of fixed condensers or resistances respectively, selected by a switch ganged to the tuning control or the wave-range switch. Specification 450,806 is referred to. Reference has been directed by the Comptroller to Specification 437,442.
