Patent GB-1284430-A (GB)
Title: Data record reading and editing system
IPC: G06K3/00
Filed: 1969-12-30
Abstract: 1284430 Paper-tape editing system GENERAL ELECTRIC CO 30 Dec 1969 [8 Jan 1969] 63272/69 Heading G4H  In a punched paper tape editing system where recorded data is read and then simultaneously punched into a new tape and printed, the punching and printing can be suspended whilst the tape reader skips a selected predetermined block length of data. A single character, word or line can be skipped upon selection of appropriate keys, repeated operation of such a key causing the reader to skip successive block lengths. Operation of a key in the middle of a block length causes the reader to skip to the next block. Punching may be suspended whilst maintaining printing and a back-space facility enables an editor to then return and punch what had been only printed. Deleted characters on the paper-tape being read are not transmitted to the printer or tape-punch. Binary encoded data from a tape-reader 1-10 is decoded (1-23) and passed through gates 1-25 and 1-24 to a local printer 1-11 and a tape-punch 1-34. Control signals are passed to the tape reader control unit 1-12 by the printer after receipt of each character. Deleted characters are determined by comparison circuit 1-32 causing the reader to advance to the next character. Operation of an omit key, after stopping the reader by key 1-13, in conjunction with one of keys 1-17 to 1-19 causes the circuit 1-26 to rapidly advance the reader to the next character, word or line, detected by comparison circuits 1-20 to 1-22, without printing or punching. However, use of the read next key 1-16 in conjunction with one of keys 1-17 to 1-19 will cause the next character, word or line to be printed and punched.

Patent GB-2049324-A (GB)
Title: Pulse detectors
IPC: G01S7/285
Filed: 1980-01-25
Abstract: A tracking pulse detector comprising a feedback loop (Q2, R6, R7) and means for adjustment of the detector bias to compensate for varying input signal levels whereby noise signals present at the input of the detector are maintained below the detector threshold thereby rendering the detector immune to false triggering. An AGC output is taken from a junction between resistors (R6, R7) of a voltage divider and a capacitor (C5) is connected between the AGC output line and an OV line, the AGC voltage output being related to the total carrier level. The average current in the detector is kept approximately constant independently of supply and signal conditions and the feedback loop adjusts the DC bias of the detector to compensate for varying signal levels, thereby keeping any input noise signals below the detector threshold independent of the level of slow varying carriers. Any carrier level variation faster than the feedback loop time constants (R6, R7, C5; R3, C2, C3) are detected. <IMAGE>

Title: Method of corrosion-resistant plating
IPC: C25D5/12
Filed: 1979-10-02
Abstract: A method of providing a highly corrosion-resistant electroplated film, which comprises first nickel plating a material to be plated directly or after subjecting it to underplating, then subjecting it to high stress nickel plating and subsequently to final luster nickel plating, and finally conducting finish plating such as chromium plating. Unlike those formed according to a conventional microcracked chromium plating method wherein chromium plating is directly applied to form microcracks in the chromium film after high stress nickel plating, the thus formed highly corrosion-resistant plated film does not contain microcracks in the final film such as chromium film. Nevertheless, it exhibits excellent corrosion resistance.
