Title: Improvements in or relating to arrangements for modulating high frequency oscillations
IPC: H03C7/02
Filed: 1936-08-14
Abstract: 466,082. Valve modulating circuits. LORENZ AKT.-GES., C. Aug. 14, 1936. No. 22463. Convention date, Aug. 19, 1935. [Class 40 (v)] Modulation of short-wave oscillators is effected by a split-anode tube placed in a magnetic field and with its anode sections connected across the oscillatory circuit to form a variable leak. As shown, a reaction oscillator R has its tuned circuit coupled to an aerial D, and across the circuit condenser C1 is connected a Lecher pair S1 S2. A magnetron tube H has its split anode connected to the respective wires Sl, S2, and the modulation voltage is applied through a transformer T to the anode-cathode circuit. The magnetic field is supplied by an electromagnet M energized by a source B. The magnetic field and the anode voltage are such that with no modulation the anode current is zero or very small; and the rotational frequency of the electrons in the tube is approximately the wave frequency. The tube H may be connected across the aerial inductance L2, Fig. 4 (not shown). The oscillator R may be replaced by a magnetron wave generator, Fig. 5 (not shown). Modulation voltage may be applied to a grid in the magnetron H, Fig. 7 (not shown). According to the Specification as open to inspection under Sect. 91, the magnetron H may be replaced by a diode valve with modulating voltage applied across its electrodes, or by a triode valve with modulation applied to its grid, the valve being placed in a magnetic field in both cases. This subject-matter does not appear in the Specification as accepted.

Convention date, Aug. 12, 1931. Drawings to Specification. [Class 38 (iv).] An electrolysis installation comprises a loadregulator having wattmeter windings acting to regulate the local apparatus supplying the continuous current fed to the cells and maintain constant power consumption in spite of variations in the internal characteristics of the cells This regulator may vary the voltage applied to the cells and the watt measurements may be taken from the circuit of a motor driving the generator of electrolysis current, from the circuit of an induction regulator or transformer feeding a rectifier or from the circuit of the cells themselves. Means may be provided to prevent exceeding certain limits of voltage or current or both by taking over control from the regulator. The regulator may be of the quickacting or of the slow-acting type.

[Class 142 (ii).] A circular loom is provided with a spool-holding shuttle, which extends to and presses against the fell of the fabric so as to beat up the weft, and a comb for controlling the spacing of one sheet of warps, the shuttle being provided with means to guide the weft, round the teeth of the comb to the fell of the fabric. A shuttle 4, formed to rest on the fell of the fabric 12 within the shedded warps 9, 10, is adapted to carry a spool 6 from which weft is led through a passage 30 to a guide eye at the base of the shuttle and is formed with a slot 21 to receive an annular warp spacing comb 23, the teeth of which project beyond the normal warp line 8. The comb 23 may be used in conjunction with a second comb 25 similarly mounted and adapted to control the other sheet of warps and each comb may be made in one piece or in two or more sections suitably connected. The shuttle may be held stationary, during rotation of the warps and the spacing means, by means of rotating vaned discs 15 which engage freely mounted flanged rollers 18 on the shuttle body, or it may be caused to rotate to increase the effective rate of weaving. The shedding may be effected by means of healds or by a suitably shaped reed and rotating discs which press against the warp. The Provisional Specification also describes the arrangement of the let-off, take-up and shedding mechanism for a circular loom and refers to a feeler member for effecting stoppage of the loom on warp breakage.

Title: Improvements in manifolding machines
IPC: B41L11/08
Filed: 1938-08-02
Abstract: 518,669. Coating surfaces. FORD, F. R. Aug. 2, 1938, No. 22775. [Class 95] [Also in Group XVI] In a manifolding machine wherein copy sheets, moistened by passage over a damping pad under pressure, pass between an impression roller 7 covered by a mirror-script copy, and a pressure-roller 24, the bearings 26 of the pressure roller and the damping member 19 are interconnected by levers in such a way that if the pressure on the impression roller is increased when the copies become faint, then the pressure on the damping member and hence the moistening is correspondingly increased. The impression adjustment is of conventional type, and is controlled by the lever 41, which occupies varying positions defined by stops 43. The damping member 19, carried by the levers 17 pivoted to the frame at 18, is raised once per revolution of the roller 7 by a cam 20. Pressure is applied to the levers 17 by the stems 44, disposed vertically above the levers 17, and having conical points 52 bearing thereon. Each stem passes through a sleeve 46, threaded externally to engage a plate 47, borne by a block 48 attached to the bearing 26. A compression spring 50 is interposed between the sleeve 46 and an abutment on the stem 44, the sleeve 46 having a milled flange 49 for adjustment. The pressure exerted on the levers 17 can be adjusted by turning the flanged sleeve 46. If the pressure on roller 24 is increased by adjusting the lever 41, the bearings 26 move together with the plates 47, and so correspondingly increase the pressure on the levers 17, and hence on the damper 19. A tie-bar 54 passes through slots 53 in the stems 44 between the blocks 48. When lowered, the damping member 19 rests upon the pad 15 in the conventional manner. Specifications 440,334, 447,184, and 458,587, [Group XVI], are referred to.

Abstract: 1496089 Selective signalling INTERNATIONAL BUSINESS MACHINES CORP 23 May 1975 [25 June 1974] 22916/75 Heading G4H In a financial transaction execution terminal, a programmable data processor connected to a plurality of subsystems in the terminal over a bus can address the subsystems to permit data transfer and control of the subsystems by the processor, the subsystems providing status signals, execution of a transaction requiring execution of a plurality of terminal functions, different terminal functions being executable in response to different control data. The processor is a microprocessor with RAM and ROS storage. The subsystems are: (a) a processor support subsystem (including interrupt logic), (b) a mechanical control subsystem (including credit card handler, cash issuer and deposit receiver), (c) a user communication subsystem (including a keyboard for entering an I.D. number for testing against a number from the credit card for user validation, amounts, and instructions for transfers between accounts &c., and a dot matrix display for giving instructions to the user), (d) a transaction statement dispenser subsystem (including a printer and a forms handler), (2) an operator function subsystem (including a keyboard, display, error log and auxiliary memory), (b) a communication subsystem (linked via a communication channel to a host data processing system external to the terminal to obtain approval of the transaction). The processor support subsystem has a hang detector to detect lack of activity on the bus to reset the terminal, returning the microprocessor to a predetermined instruction. The user can also reset manually. A run detector is also provided, controlling "running" and "intervention-required" lamps. Some conditions in subsystems cause interrupt requests, but in general status indications are read on the initiative of the microprocessor at regular intervals. On power failure, a battery is switched in to power the auxiliary memory in the operator function subsystem and the microprocessor is interrupted to control storing of vital data in the auxiliary memory for protection.
