IPC: G10F1/18
Filed: 1926-11-19
Abstract: 274,697. Wade, H., (Mills Novelty Co.). Nov. 19, 1926. Keyboard stringed instruments; tuning-pins and straining elements.-In a mechanical violin, the strings 1 secured with a worm adjustment at 4 to horizontally arranged levers C, C<1> pivoted at 2, are tensioned by springs C<2> adjustable by screws 9, tremolo devices D. D' being also attached to the levers C, C<1>. The springs C<2> are preferably arranged so that increased or decreased leverage about the pivot 2 caused by tilting of the levers C, C' under the tremolo, is compensated by decreased or increased tension in the springs. For the tremolo, pulsations, which are of different character for the different strings. are supplied by an air pump to the cylinders 5 containing light pistons 5<a>. Specification 260,167 is referred to.

Title: Improvements in electron discharge devices
IPC: H01J19/02
Filed: 1923-11-21
Abstract: 207,537. British Thomson - Houston Co., Ltd., (Assignees of Hull, A. W.). Nov. 21, 1922, [Convention date]. Thermionic amplifiers and generators - The cathode is adapted to produce a current of such strength that the strength of the magnetic field produced thereby is sufficient to increase over a certain range the slope of the grid-voltage and space-current curve and to produce an abrupt change at a critical grid voltage. A negative resistance effect may be obtained by secondary electron emission from the grid with a resulting increase in current. As shown, a cathode 1 of large diameter is surrounded by a grid 2, formed of slats, and an anode 3. A lead 5, sealed into the container, is connected with the cathode through a tungsten spring 9 and flexible conductors 10 which carry most of the current. The grid is supported by bands 11, 12 mounted on tubular portions of the container and the band 11 may be free to move axially so as to allow expansion. The anode is supported by bands 16, 17 in a similar manner. In order to increase the secondary emission the grid may consist of a number of flat rings arranged at right angles to the axis of the tube and spaced apart on supporting arms. In one arrangement for generating oscillations an inductance in the anode-circuit is coupled with an aerial inductance and acts regeneratively on a coil in the grid-cathode circuit. In another arrangement for the same purpose a grid-cathode circuit comprising an inductance and a variable condenser is tuned to the desired frequency, and an inductance in the anode-cathode circuit is coupled with an aerial inductance. A positive charge may be impressed on the grid at starting by connecting it with a point on the high tension battery. Specifications 182,516, 185,752, and 189,125 are referred to.

Title: Apparatus and methods for observing nuclear magnetic resonance spectra
IPC: G01R33/46

Abstract: 1,215,961. Gyromagnetic reconance apparatus. SPECTROSPIN A.G. June 20, 1968 June 20, 1967], No.29444/68. Heading G1N. A nuclear magnetic resonance spectrometer is provided with a cathode ray oscillograph K having a display width of at least 2, 000 times the optimum resolution of the eye and 1, 000 times the diameter of the smallest image spot. The time base of the oscillograph is synchronized with the magnetic field sweep or frequency sweep of the spectrometer. Rapid adjustment of the resolution of the spectrometer is possible by observing the oscillation decay phenomena occurring upon traversal through a resonance line. Also, rapidly changing spectra during chemical reactions may be recorded by photographing the spectrum displayed on the oscillograph. As shown in Fig.3, a cam mechanism controls the timing of the spectrum scans, the exposure time of the camera being adjustably set on a release mechanism A. The time between scans is adjustable by adjusting the rotation speed of the cam.

Title: System for monitoring or checking the decoding of an address
IPC: G06F/
Filed: 1971-06-23
Abstract: 1351479 Checking decoders JEUMONTSCHNEIDER 23 June 1971 [25 June 1970] 29444/71 Heading G4H  Decoding of an address is checked by comparing, using relays, the outputs of a plurality of diode re-encoding matrices. An address decoder in a data transmission, remote control or remote monitoring system may consist of two decoders the outputs of which are combined to a single 1-out-of-n output in a relay matrix. This output can be checked as in the drawing where the 32 relays have respective contacts in 8 groups of 4 at the left. The contacts of each group are connected via diodes D 1  to a row, respective to the group, of a diode matrix M 1 , and contacts of a given position within each group are connected via diodes D 2  to a row, respective to the position, of a diode matrix M 2 . The matrices M 1 , M 2  give binary-coded outputs, in true and complement form, to relays U, contacts of which are used in a comparison device to check identity and/or complementarity of the outputs. The polarities shown may be reversed. The relays U may be replaced by transistors controlling semi-conductor devices. More than two matrices M 1 , M 2  may be provided, in which case each row of matrix M 2  would correspond to a sub-group (rather than one) of contacts in each group of the contacts at the left, and so on, with the last matrix having each row corresponding to one contact per group.

Title: Improvements in and relating to machine tools with a continuously variable drive
IPC: B23Q5/16
Filed: 1951-12-18
Abstract: 703,514. Lathes. PATENTVERWERTUNGS. W. REIMERS GES. Dec. 18, 1951 [Feb. 2, 1951], No. 29573/51. Class 83 (3). [Also in Group XXIV and XXXVIII] A device, for maintaining constant cutting speed in machine tools in which the work is rotated, comprises means 4 associated with the tool-feeding mechanism 2 and means 11 associated with a cutting-speed adjusting device 9, which means respectively transmit forces proportional to the logarithms of # times the work diameter (d) and of the cutting-speed' (v) to a member controlling the machine motor. The feed screw 2 and the cutting-speed device 9 rotate the cams 4, 11 which compress springs 5, 8 to control the position of a lever 6 and so of a valve 12. The valve 12 controls the hydraulic pressure in a line 18 connected to a cylinder 19. The cylinder 19 contains a piston 20 acted upon by a spring 21 which is compressed by a cam 22 rotated by the shaft 23 of a speed adjusting device for a continuously variable gearing 24, the force of the spring being proportional to the logarithm of the rotational speed (n) of the spindle 26. Equilibrium of the piston 20 is thus established on the basis, of' the relationship. log v=log n+log (d#). If the; piston 20 is not in equilibrium, a lever 28 is moved to engage one of two contacts 29, 30 to cause the continuously-variable gearing 24 to be adjusted. In a modification, the forces of the springs 5, 8 are transmitted to a lever 55, Fig. 2, engaging a bar 50 supported on knife-edges 52. The force of the spring 21 is transmitted to. a lever- 57 which engages contact 29 or 30. when the bar 50 is not in equilibrium. In a further modification, the variations in position of the slide: 1, Fig. 3, vary the current in a coil 36 causing a core 33 on a swinging arm 32 to bedisplaced. The cutting- speed adjusting device 9 similarly controls the position of a core 34. Equilibrium is established when, by the making of one of the contacts 29, 30, the adjusting motor is energized to move the continuously variable speed control 23 to readjust the current in a coil 38 and move the core 35. The latter arrangement can be modified by mounting the coils 36, 38 on the arm 32.

In an intercepting circuit for connecting a calling line to an announcement machine, ringing current on wire R activates a transistor 16, shunted by a smoothing capacitor 24, to energize a relay 20, whereupon the ringing is tripped by the connection of a gas-tube 21 across wires T, R, and relay 20 is maintained by talking battery connected to either wire. Relay 20 controls a second relay 40 which completes the connection to the announcement machine and applies a start signal thereto. A peg counter 50 is operated by the sequential release of 20, 40 when the caller hangs up. Relay 40 may be omitted if relay 20 is provided with contacts which are slow-to-operate in relation to the remainder.
