Title: A circuit for a touch keyboard

IPC: H03K17/96
Filed: 1966-02-12
Abstract: 1,134,704. Typewriters &c. keyboards. INTERNATIONAL BUSINESS MACHINES CORP. 12 Feb., 1966, No. 6315/66. Heading B6F. [Also in Division H3] A circuit for use in a " touch keyboard " comprises a capacitor 6 arranged to be charged via one path 8 and discharged via another path and provided with means for blocking the discharge path so that a charge builds up on the capacitor 6. As described, capacitor 6 tends to charge via diode 8 during positive half-cycles of a positively-biased square wave at terminal 5 and tends to discharge via diode 10 during negative half-cycles at 5. The introduction of a capacitance 4 of an operator touching a terminal 3 or a dielectric applied thereto, will result in capacitance 4 charging via diode 11 during positive half-cycles at 5 so as to block diode 10 and thus prevent discharge. The voltage on capacitor 6 thus builds up incrementally until the cold cathode tube 2 becomes triggered, illuminating the key associated with terminal 3. In Fig. 3 (not shown) anti-phased or other square waves are applied to separate terminals associated with resistors 7, 9.

The cooking pot opening is provided with a cover 228 having a ring of apertures 230 through which oil passes to the filter bowl and supporting a baffle having an imperforate section to direct crumbs away from the filter and a perforated section. Crumbs are removed from the chamber 192 to a collecting receptacle by a belt conveyer located in housing 190 provided with means for removing crumbs from the conveyer. Oil is stored in a tank 326 and heated in a heater tank 360 under the control of a thermostat 404. High and low temperature thermostats 370, 382 control the temperature in the cooking pot. An overheat thermostat 410 is provided on the heater tank to prevent overheating of the oil. The storage tank 326, heater tank 360, cooking pot 130, filter bowl 178 and a pump P are connected by tubing as shown, the oil flow through the tubing being controlled by solenoid-operated valves V1, V2, V3 comprising valve-members AB, CD, EF respectively. The valve-members are operated under the control of an electric circuit comprising a system of relays and timers Figs. 26, 27 (not shown) to perform the following operations: Filling cooking pot Valves A and F open Circulating oil through the cooking pot Valves D and F open Circulating oil through the heater tank Valves C and F open Storing oil Valves B and D open Pumping out crumb well Valve D open Emptying storage tank Valve A open Emptying heater tank Valve E open.

Title: Improvements relating to mincing machines
Inventor: FENTIMAN DENIS RICHARD
IPC: B02C18/30
Filed: 1964-02-17
Abstract: 1,007,443. Mincers. GLOBE SLICING MACHINE CO. Inc. Feb. 17, 1964, No. 6526/64. Heading A4C. The barrel 12 containing the feed worm 4 and cutting disc 15 of a mincer is releasably locked to the sleeve 6 of a fixed casing 1, the connection being made by pushing and rotating the annular barrel end 11 into an annular portion 10 of the sleeve 6 with a fixed pin 17 projecting inwardly of the sleeve 6 engaged in an inclined or L-shaped recess 18 formed in the barrel end 11 and being locked when the pin 17 reaches the end of the recess 18 by rotating a handled pin 20, 27 housed transversely in the sleeve 6, the handled pin 20 being formed in its cylindrical shank with a recess 23 which conforms with the inner surface of the annular portion 10 to permit entry of the barrel end 11 whereafter rotation of the pin 20 engages the latter in a recess 19 in the barrel end 11. The arrangement is such that the handle 27 cannot be swung down to the locking position of the pin 20 until the feed hopper 14 is properly aligned in the vertical position so that if, before locking the pin 20, rotation of the cutter locking ring 28 in the clockwise direction, as viewed from the right of Fig. 2, causes rotation of the barrel 12 to disengage the pin 17 from the end of the recess 18 the locking handle 27 cannot be swung down. In operation the worm 4 rotates anticlockwise, as viewed from the right in Fig. 2, whereby any tendency to rotate the barrel 12 serves to retain the fixed pin 17 in the recess 18. The locations of the pin 17 and recess could be interchanged. A grub screw 30 retains the pin 20 in the sleeve 6 by engaging a nicked portion of the pin 20. The hopper 14 is anchored to a feed pan by a spring pressed pin 15. The squared end 2 of the worm shaft 3 engages the drive motor shaft.

Addition to 319,312, [Class 138 (ii), Washing, mangling, &c.]. [Class 2.3.] The perforated clothes receptacle c<1> of a washing-machine is rotated in a clockwise direction on its own axis and simultaneously the receptacle moves along an inclined path in a counterclockwise direction about a pivot b<1>. The latter motion is derived from the engagement of an arm f on the shaft of a motor i with a roller d on a shaft d<1> projecting from the lid c<2> of the receptacle. The rotation on its own axis is caused by the engagement of a surface e<1> on the receptacle with an annular track e<2> inside the stationary casing a. For centrifuging, a disc is placed under the pivot b<1> to hold the receptacle vertical, the shaft d<1> then being coupled directly to the motor shaft. The machine may, alternatively, be driven by a hand-crank i<2>.

Patent GB-373309-A (GB)
Title: Improvements relating to the use of thermionic valves
IPC: H04L25/24
Filed: 1931-03-06
Abstract: 373,309. Valve circuits. EVANS, G. T., Linden, Edgware Road, Cricklewood, London. March 6, 1931, No. 7031. [Classes 40 (iii) and 40 (v).] Thermionic relays of the kind employing two valves reciprocally coupled by means of resistances are modified by including one of the resistances in the input circuit of the first valve, and in the plate circuits of both valves. By choice of suitable values of resistance in relation to the valve characteristics, a sudden discontinuous change in the plate currents is caused by applying D.C. voltage of one sign to the input grid, whilst a subsequent input voltage of the opposite sign restores the plate currents to their original value. As shown in Fig. 1, the first valve V1 has in its grid circuit a bias battery 4, the input terminals 3 and a resistance R, whilst its plate circuit includes a coupling resistance R1, the battery 1, and the resistance R. The grid of the second valve V2 is connected through a reversed battery to the plate of the valve V1, and the plate circuit comprises a relay or output impedance 2, the battery 1 and the resistance R. The second valve is of lower impedance than the first. If valve V1 is initially adjusted to pass zero or little current, a positive input voltage applied at 3 increases that current and reduces the grid voltage of the second valve. Less current passes through this valve and through the resistance R which adds further positive voltage to the grid of the valve V1. The changes are therefore cumulative and if the input voltage is sufficiently high the plate current of valve V2 falls suddenly to zero. If the input voltage is reversed, the plate current of V2 suddenly rises to its initial value, thus giving a trigger action in both directions. The input voltage necessary to effect the triggering may be reduced to a low value by suitable choice of the resistance R. In a modification shown in Fig. 2, indirectly-heated valves are used, the heaters being connected across a supply source 6. A potentiometer R4, R5 also across the source 6 supplies grid bias to the valve V1, whilst a further potentiometer comprises the coupling resistance R and two resistances R2, R3 which supply the plate voltages for the respective valves. The output impedance 2 may be in the plate circuit of either valve, or it may be inserted in the plate circuit of a further valve which has its grid excited by suitable connection to the circuits of the valves V1, V2. The relay can be used as a repeater of direct-current impulses in line or cable telegraphy, serving to correct distorted signals. When the marking and spacing impulses are differentiated by their tone frequency, these may be rectified and applied as impulses of opposite sign to the input grid. The relay may also be used as a voiceactuated switch in a telephonic echo suppressor. Specification 139,867, [Class 40 (v), Wireless signalling &c.], is referred to in the Provisional Specification.
