Title: Fastenings for attache cases, bags, portfolios, and the like
IPC: E05B65/50
Filed: 1945-04-21
Abstract: 590,844. Case fastenings. CHENEY & SON, Ltd., C. W., and CHENEY, C. W. April 21, 1945, No. 10070. [Class 44] In a fastening for attache cases, &c., a keyhole cover-plate 5 and a knob 4 are shaped from a single blank of metal, and are combined with a bolt-locking device. The knob, having an axial split peg 6 which passes into the casing through a thin washer 7, accordingly connects with a circular hole 2e in the bolt 2, and engages an elongated hole 3a in the blocking member 3 disposed closely within the dishing of the bolt, the tips 6c of the peg being spread to secure it in place. Thus the bolt, blocking member, cover-plate and knob can slide together, and the latter three can revolve together in the circular hole 2e. The knob 4 and cover-plate 5 have ears 4a, 5a clinched down over a shape plate 6a which provides the peg 6. The shallow, dish-shaped bolt 2, with a nose 2a, is pierced at 2c for clearance, and has a rigid stop-lug 2d. The blocking member 3 provided with a V-nose 11 has a stop shoulder 12 and a projection 13 which contact the lug 2d to limit movement of the bolt; the projection 13 also coacts with an abutment 14 pressed out of the front plate 1. Within the dishing of the bolt 2 is a spring 141 having two limbs 15, 16 co-operating with the nose 11 of the blocking member 3, with the key-locking mechanism (not shown), and with the casing. Specification 374,110 is referred to.

Title: Improvements relating to microphones
IPC: H04R1/00
Filed: 1969-02-28
Abstract: 1,248,088. Digital microphones. INTERNATIONAL BUSINESS MACHINES CORP. 28 Feb., 1969 [1 March, 1968], No. 10803/69. Heading G4H. [Also in Division H4] In a condenser microphone, switching elements 10 to 15 are electrically coupled with a flexible electrode 1 and the number of switching elements 10 to 15 which change their states is a function of the distortion of the flexible electrode 1. The arrangement permits conversion of an acoustic signal into a digital electric signal for pulse code modulation use. Preferably the switching elements 10 to 15 are field-effect transistors with the flexible electrode 1 as a common gate electrode. Electrode 1 is a parabolic elongated diaphragm and the switching elements 10 to 15 are placed along the projection on a plate 2 of a radius of the electrode 1. The F.E.Ts 10 to 15 are followed by sampling circuits 20 to 25 which are controlled by a sampling control circuit 30. Each output of sampling circuits 20 to 25 is fed to a codling matrix 40 which converts 2<SP>n</SP> sampled input signals into n binary output signals. A clock 30 triggers the sampling circuits 20 to 25 so that their output signals are received serially by the coding matrix 40. At each particular value for the elongation of the diaphragm, one part of the F.E.T. arrangement is in the conducting state whilst the other part is non-conducting. The line of demarcation is found by sampling circuits 20 to 25 including "EXCLUSIVE OR" circuits. Two adjacent sampling circuits 20 to 25 are compared and an output is given only if one is conducting and the other is non-conducting i.e. an output signal is given only from that sampling circuit which is wired with the sampling circuits defining the line of demarcation. The circuitry comprising switching elements, sampler circuits and coding circuits may be a single semi-conductor chip fabricated using the Mesa technique.

Title: Improvements in or relating to mosaic screens for cathode ray tubes
IPC: H01J29/43
Filed: 1935-04-08
Abstract: 454,937. Cathode-ray tubes. WHILEMS, C. J., 21, Highcliffe Gardens, Ilford, Essex. April 8, 1935, No. 10880. [Class 39 (i)] Mosaic screens of cathode-ray tubes for television transmission &c. are produced by forming photo-mechanically on an insulating sheet a resist which serves to prevent the transfer of metal to, or its removal from, the parts of the sheet covered by the resist, and which is itself finally removed. A glass or mica sheet is covered with bichromated photoengraving glue and a contact or other print is made thereon from a negative which is a photographic reduction of a large-scale drawing. After washing to leave a meshpattern resist of fixed glue on the sheet, silver is deposited chemically or by evaporation or sputtering and the resist together with any metal deposited over the resist is removed, as by immersing or rubbing in an alkaline solution, to leave on the sheet the mosaic of silver deposited at the apertures in the resist. Processes involving the use of bichromated gelatine or albumen, bitumen, or light-sensitive resins as described in Specification 265,769, [Class 98 (ii)], may be used to form the resist. In a modification, a silver coated sheet is provided with a resist of separated areas, the silver not covered by resist is removed by etching or electrochemically and the resist is finally removed by solution or mechanically to leave silver on the areas originally covered with resist. To prevent permeation of the resist by the etching agent, it is protected by greasy inks. If lightsensitive synthetic resins are used, hydrofluoric acid may be used for etching. To improve the photo-electric efficiency of screens made by depositing silver chemically, a thin layer of silver is evaporated or sputtered on to the silver mosaic and is aggregated at a high temperature.

Abstract: 1,179,585. Electronic calculators. ELEKTRONISCHE RECHENMASCHINEN. KARLMARX-STADT. VEB. 8 March, 1967, No. 10963/67. Heading G4A. [Also in Division H4] An electronic desk calculator is adapted to generate dialling pulses. As described a four rules machine has an. indicating device comprising a plurality of gas tubes or a cathode-ray tube. A telephone number entered through the keyboard is stored in a register (e.g. the accumulator) in binary coded decimal form. The number is decoded digit by digit by a counter which receives a digit in binary coded form and is counted down to zero by clock pulses supplied from the exchange or by division of the clock frequency of the calculator. A corresponding number of clock pulses are gated to line as dialling pulses through a gate which is closed when the counter reaches zero. The contents of the register are shifted to the left and the next digit supplied to line. The printing mechanism of the calculator may be used to determine the most significant digit and the decimal point mechanism may be employed to effect the transmission of zeros. Transmission to line is effected only when a handset is lifted from a hook switch on the calculator or when a change-over switch is operated. The number is stored in the calculator until transmission has been completed and is available for visual checking or repeated sending.
