Title: Improvements in or relating to record card controlled printing machines
IPC: G06K15/04
Filed: 1941-12-17
Abstract: 554,105. Typewriters &c. BRITISH TABULATING MACHINE CO., Ltd. Dec. 17, 1941, No. 16310. Convention date, Dec. 18, 1940. [Class 100 (iv)] In record-card controlled mechanism comprising a type-carrier yieldingly urged into extreme position, a zoning-member movable parallel to the typecarrier is provided with a stop-pawl for coupling the zoning-member and type-carrier under control of a digit role, and another stop, controlled by a zoning role, co-operates with the zoning-member to limit further movement of the zoning-member and typecarrier. In the mechanism shown in the Fig., a type-bar 42 is raised, in synchronism with the movement of the record-card past reading-brushes LB, by means of an arm 40 which is connected to a spring 43 and is released and restored by a bail 39. A stop-pawl 80 for the type-bar is pivoted on a vertically movable zoning-bar 76, and co-operates with a pivoted finger 81 on a latch 78 is connected with the armature 83 of one of the reading-magnets 19. The latch co-operates also with a zoning-stop 77 adapted to engage notches o, x, r and a shoulder n on the zoning-bar. Before the 9-point passes the brushes bails 61, 71 free the stop-pawl 80 and latch 78. During passage of points 9 .. 0, the zoning-bar 76 and zoning-stop 77 are held by bails 51, 56. When the 8-hole, for instance, is read, the stoppawl 80 is released and engages the 8-notch in the type-bar. After the 1-point has been read, a bail 71 restores the latch and the bail 51 permits the zoning- bar to rise until the zoning-stop engages the shoulder n, the stop-pawl 80 causing the type-bar to rise with the zoning-bar until the 8-type is positioned. If a hole occurs also at the point 0, 11, or 12, the stop 77 is again released and engages the notch o, x, or r to arrest the type-bar when the y, q, or h type is positioned. When the 0, 11, or 12 hole occurs alone, the stop-pawl engages the 0-notch in the typebar, the zoning-stop engages the notch o, x, or r and one of the bottom three types is positioned. To permit of easy release of the stop-pawl by the bail 61 when the type-bar has been arrested after short movement, and is consequently under strong pressure from the spring 43, the type-bar is restrained by co-operation of one of a series of notches 7 . . * therein with a pawl 106 controlled by a bail 101. Specification 418,228 is referred to.

Title: Improvements in electrical systems of remote control
IPC: H02J13/00
Filed: 1937-06-12
Abstract: 489,134. Electric control systems. GENERAL ELECTRIC CO., Ltd., COLLYER, J. E., and SMART, N.C. June 12, 1937, No. 16333. [Class 40 (i)] In a system for controlling switching relays over a power network by superposed currents, a guard relay is provided at the transmitter and, if operated by interfering currents, effects the transmission of a control current, which restores or ensures that the switching relays occupy their correct positions. As shown control currents of two different frequencies produced by a generator GR are superposed on a network 1 .. 4 for operating two-position relays (not shown) which may be of the type described in Specification 489,118, wherein a differential mechanism is operated in reverse directions by the different frequencies. To prevent incorrect operation of the relays by interfering currents, a relay LC of simliar type but of greater sensitivity is provided at the transmitter. Normally, operation of a clockcontrolled or manually-operated switch CS into contact with one or other of its contacts operates relays ST, A or B over contacts LC1 of relay LC. Relay ST starts the driving motor of the generator GR and relay A or B applies the appropriate frqeuency to the line at contact A2 or B2 and locks up over a thermostatically operated relay T which releases the relays and terminates transmission of the signalling current after a predetermined time period. Relay LC is operated into its alternative position simultaneously with corresponding operations of the control relays. In the event of the presence of interfering currents which tend to restore the control relays, relay LC restores and pulls up relay A or B and thereby effects the transmission of signalling current which nullifies the effect of the interference. The signalling currents may be applied to each phase lead of the network by a transformer and a guard relay may be provided for each phase. Specification 481,213 is referred to in the Provisional Specification.

Abstract: 110,957. British Thomson-Houston Co., (General Electric Co.). Nov. 17, 1916. Controllers, liquid; actuating-mechanism for.-A multistage compressor driven by a motor having a limited range of economical speed is regulated to give increasing volume of air at increased pressure as the process concerned proceeds, by first utilizing a limited number of stages and increasing the speed from minimum to maximum and then cutting additional stages into service at minimum speed, the sequence of operations being repeated. Fig. 1 shows a compressor 5 with outlets 6, 7, 8, 9 controlled by valves and discharging to a steel converter 12. The electric motor 30 has in circuit a liquid resistance variable by the movement of plates 29, carried by a lever 22a jointed to a second lever 22 which is controlled by a volume governor consisting of a float 19, in the inlet to the compressor. Such a governor is described in Specification 22,447/08, [Class 57, Governors &c.], but for the present purposes the lever 22 supports a weight 24 which is moved inwards by a motor 26, which mav act continuously or intermittently, and thus permit a larger flow of air as the process concerned goes on. At the beginning of the process, the motor drives the compressor at minimum speed and discharge takes place from outlet 6. The motor 26 is started and the weight 24 is moved towards the left of the drawing thus cutting out resistance from the circuit of the motor 30 until its maximum speed is reached. The contact 33 in a signal circuit is then closed and the attendant opens conduit 7 and closes conduit 6. The consequent rush of air causes the float 19 to rise and put all the resistance again into the motor circuit. The weight 24 continuing its travel gradually cuts out this resistance and the sequence of operations is repeated at each outlet from the compressor.

Title: Improved circuits for the amplification and/or frequency transformation of electrical oscillations
IPC: H01J25/68
Filed: 1935-06-08
Abstract: 457,928. Valve amplifying circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. June 8, 1935, No. 16720. Convention date, Aug 9, 1934. [Class 40 (v)] A screen-grid valve employed for the amplification or frequency transformation of electric oscillations has a low potential applied to its output electrode, and a high potential on the screen so as to set up a space charge between these electrodes the magnitude of which is controlled by oscillations applied to the input electrode. As shown in Fig. 1, the input I is applied between the control grid CG and the cathode K of a tetrode valve V1. A screen grid SG is connected to the cathode K through a battery B and a resistance R shunted by a condenser C. The plate P, which may be on the outer wall of the valve, is connected through the output impedance II and earth to the end of the resistance R. Screen-grid current through the resistance R thus gives a negative bias both to the input grid CG and to the plate P. When several valves are connected in cascade the plate P of one valve is directly connected to the input grid of the succeeding valve V2, V3. The plate P does not receive electrons, but its voltage is varied by the varying space charge in the area between the screen grid SG and the plate P. For the wavelength range 15-50 metres, the distance between the screen grid and the plate may be 10mm. For shorter waves this distance may be reduced, and for longer waves greater amplification is secured by increasing the spacing. The control grid should be of small size, or should be close to the screen grid ; and the space between these grids may be divided by a partition. In an alternative arrangement, the input is applied to a grid placed between the screen grid SG and the highly-positive plate P, and the output is taken across an impedance connected between an inner grid and the cathode. When several electrode systems are placed in a common envelope E, Fig. 2, a common cathode K and a common biassing arrangement RC are used ; the connexions from plates to control grids are internal, and the screen grids are connected together internally.
