Adding and subtracting apparatus. - In machines of the key-set lever-operated type having flexible keyboards, the keys are constructed from sheet metal and the locking plates therefor are so mounted as to move into the locking position under the action of gravity. Each bank of keys with the associated mechanism is mounted as a unit, actuation being obtained by the engagement of pins on the keys with differentially sloping members on longitudinally moving plates. Movement of the plates is communicated to pinions carried by setting shafts adapted to be engaged and rotated, to amounts corresponding to the keys depressed, by cylinders bearing stepped teeth. Restoring devices for the longitudinally moving plates, an error lever, and releasing means for the key locking plates are provided.. Keys; keyboards; keyboard interlocks.-The keys are formed from sheet metal and provided with shanks 16, Fig. 6, feet 15. and body portions 25 which are bent at right-angles to form wings 26 having sloping faces 27, locking faces 28, and stop faces 29. Mounted in the sections are locking angle-plates 54 provided with lugs 55 by which they are pivoted, the pivots being so situated that the locking-plates are swung against gravity by the faces 27 and engage the faces 28 to lock the depressed keys. Release on the completion of an item is effected by a bell-crank lever 57, Fig. 2, rocked by a cam 56 on the crankoperated shaft 6.

Title: Improvements in tuning indicators for radio echo apparatus
IPC: H03J3/14
Filed: 1941-11-05
Abstract: 603,145. Radiolocation radio - receiving circuits. GENERAL ELECTRIC CO., Ltd., and ESPLEY, D. C. Nov. 5, 1941, No. 14260. [Classes 40 (v) and 40 (vii)] To facilitate the tuning of the superheterodyne receiver to the frequency of transmission in a pulse radar system, a signal is fed from the transmitter directly to the local oscillator of the receiver, where, due to non-linearity in the oscillator, mixing occurs, thereby producing a signal of the intermediate frequency which is applied to a tuning indicator. Exploring pulses from the transmitter T are radiated from the aerial S where echo signals are also received and fed, through the gas T.R. switch R, to the tunable crystal mixer M. A signal is tapped off from the transmission line feeding the aerial and is fed into the local oscillator LO which compresses a triode of the disc seal type fitted into the end of a tunable double coaxial transmission line. The intermediate frequency signal from LO is selected by the circuit 21, amplified at A and passed on to the magic eye tuning indicator 1. Suppression circuits SUP1, SUP2 are provided to prevent unwanted signals from being passed on, the suppressor SUP1 paralysing the 1.F. amplifier of the receiver during the transmission of the exploring pulse, and the suppressor SUP2 paralysing the amplifier A at all other times.
