Abstract: 463,201. Electric clocks. BUECHE, H. Oct. 31, 1935, No. 30134. Convention date, Nov. 1, 1934. [Class 139] An electric clock has (a) electric contacts, of which one contact 11 fixed on the balance staff 6 has inclined faces to coact with a blade spring 5 forming the second contact for the electromagnet 4 which re - energizes the balance, and (b) an armature 12 on the balance staff which carries a pin 20, the latter in one direction of movement rotating a ratchet wheel 16 which is connected to the hands and in the return direction. wiping past the ratchet wheel by lifting the latter bodily without rotating it. As the contact 11 moves to the left, Fig. 6, it contacts with and raises the blade 5 substantially so that magnet 4 gives an impulse to the armature 12. In the return to the right, the contact 11 depresses the blade 5 slightly for a comparatively short time so that the magnetic action has no effect on the armature. Wheels and arbors.-One end of the spindle 21 of the ratchet wheel 16 bears in a slot in a smooth pipe 18 so that as the pin 20 returns to the right, Fig. 6, its inclined face lifts the wheel 16 whilst the aligning spring 22 prevents rotation of the wheel.

Filed: 1931-11-02
Abstract: 379,556. Ink-ribbon mechanism. HOCHMAN, J. C., 67, West 44th Street, New York, U.S.A. Nov. 2, 1931, No. 30313. Convention date, Nov. 8, 1930. [Class 100 (iv).] In a duplicating arrangement for typewriters, a length of ink ribbon is mounted in a loose frame which rests on the platen and has limited longitudinal and peripheral freedom. The frame F shown in Figs. 2 and 4 comprises a cross-bar 25 formed with curved arms 26 to which a duplicating-ribbon R is attached. The cross-bar is formed also with a flange 25a, a finger-piece 27, and stop-lugs 28, 29 for co-operating with stops such as the yokes 17 of the paper-fingers 16, and the arms are formed with lugs 30 having notches 31 for receiving the offset parts 22 of the paper-fingers. The duplicating-ribbon is provided at each end with a clip 36, Fig. 6, formed with a tapering pocket 51 for engaging the tapering end 35 of the associated arm. The clips are pushed on to the arms and are retained by notches 42 therein, the tapering parts of the clips and arms causing the duplicating-ribbon to be tensioned. After the paper-fingers have been raised, the frame is placed over the copy sheet on the platen 11, and the paper-fingers are depressed to bring the offsets 22 into the notches 31. During operation of the machine, the frame shakes longitudinally and peripherally and thereby causes distribution of wear of the duplicating-ribbon, the shaking movements being limited by the stop-lugs 28, 29 and notches 31. If additional copies are required, one or more additional frames with attached duplicating-ribbons are superposed on the frame F, the additional frames being formed without the lugs 28, 29, 30 and being retained in position by the lugs 30 and flange 25a. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a ribbon-holding frame which is permanently mounted on the machine. This subject-matter does not appear in the Specification as accepted.

Abstract: 817,822. Testing radio apparatus. SANGAMO WESTON Ltd. Oct. 28, 1955 [Oct. 29, 1954], No. 30921/55. Class 40 (5). [Also in Group XL (b)] A test signal generator comprises a single multigrid tube 25 with inductive anode load 31 and an associated manual switch A-D such that (1) in one position of the switch the tube acts as an amplifier of a signal applied at input terminal 60 with output at terminal 87; (2) in a second position (as shown) a gas-filled tube 21 is connected across the amplifier anode inductance so that the tube flashes, is extinguished, and flashes again as the input to the tube passes through zero frequency, this being derived by beating in a mixer stage a signal from a variable-frequency oscillator with a fixed calibrating frequency from a crystal oscillator so that the variable-frequency oscillator is checked, or another frequency beat with the oscillator in the mixer can be measured; (3) in a third switch position (400 c/s.) the tube is connected as a low frequency, e.g. 400 c/s., oscillator with inductive feedback from anode to control grid and modulates across a rectifier 93 a radio-frequency input at terminal 95 from the variable-frequency oscillator; (4) in a fourth position (300 kc/s.), a tuned circuit 41, 38, 43 is connected across the control and screen grids of the tube to form a Colpitts oscillator of frequency, e.g. 300 kc/s., also applied to modulate the R.F. input at terminal 95 across rectifier 93. The modulation frequencies in each case may be used for producing horizontal and vertical bars on a television receiver screen for checking vertical and horizontal linearity respectively. When the tube 25 acts as an amplifier the output at terminal 87 is applied to the vertical deflection electrodes of the cathode-ray tube and the input (at terminal 60) is rectified by rectifier 69 or 70 so that either a positive or negative deflection may be obtained. Specifications 817,633 and 817,821, [Group XXXVI], are referred to.

Title: Improved apparatus for the control of energy supplied to an electrical translating device

Filed: 1946-10-18
Abstract: 642,895. Automatic control systems for D.C. motors. IGRANIC ELECTRIC CO., Ltd. Oct. 18, 1946, No. 31049. Convention date, Oct. 20, 1945. [Class 38 (iv)] In a speed control system for D.C. motor 10 in which a resistance 13a in series with the armature 10a is varied by a motor 14, the direction of rotation of the motor 14 is determined according to which of its two fields 14c, 14b is energized through a valve and relay selector system operated by a D.C. voltage produced by the difference between a reference voltage at resistor 33 and the output of a tachometer generator 11, driven by the motor. Hunting is prevented by a relay producing adjustment of the reference voltage to allow for the mechanical inertia of the motor 14. General operation.-As shown, upon closure of the start button 18 relays 12 and 17 operate and the motor rotates at the lowest speed, resistor 13a being fully in circuit with armature 10a. Grid 28c is positive relative to cathode 28a, the voltage of tachometer 11 is low and valve 28 conducts, thereby causing valve 38 to cut-off, valve 42 to conduct and relay 21 and 23a to operate. The forward field 14b is energized by relay 16 and the contact arm 13c is moved to reduce the amount of the resistor 13a in series with armature l0a and motor 10 accelerates until the rising tachometer voltage at grid 28c causes a reduction in the energization of relay 21 wherein field 14b is de-energized and motor 14 stops. Similarly, a reduction in the datum voltage, by an adjustment of tapping 33a while the machine is running will cause valve 48 to operate relays 15, 20, 22 and energize field 14c to reverse motor 14. Anti-hunting system.-To prevent hunting, due to the overshooting of the correct position of the contact 13c due to mechanical inertia, the contacts 23c are opened by relay 23 to reduce the value of the tachometer voltage, and therefore the motor speed, at which the - de-energization of the field 14b occurs. The motor 14 is therefore de-excited before the correct setting of 13c is reached and the system inertia carries it forward to the correct position. Similarly, when the tapping 33a is adjusted to a lower speed, hunting is prevented by opening of contact 22c. To effect a difference in the response rates of relays 20, 21 during energization and de-energization, the resistors 43, 49 are in parallel with the diodes 44, 50 respectively. Specification 637,012 is referred to.
