Title: A method and apparatus for generating electric signals
Inventor: HOPKIN PETER ROY
IPC: H04N5/76
Filed: 1961-10-18
Abstract: 989,103. Electric record/playback processes. S. SMITH & SONS (ENGLAND) Ltd. Jan. 14, 1963 [Oct. 18, 1961], No. 37420/61. Heading G5R. Parts of a high-resistance, thin, light coloured layer 11, Fig. 2, coated on to a lower-resistance, desk-coloured layer 12, in turn coated on to a conductive base layer 13 are eroded by current fed from a record/playback electrode 14 to produce a visible record of variable surface resistivity replayable by modulation of a current or potential applied to the electrode 14 of less-than-recording intensity. In Fig. 3, the playback electrode 19 follows arcuate transverse tracks on a tape 10, the signal return path being a platen 17 contacting the conductive base 13, Fig. 2. High-frequency noise, due to the necessarily intermittent nature of the contacts representing a lower frequency signal are removed by a filter 27. In Fig. 4, the electrode 19 is drawn transversely across the tape by an endless belt 30. The electrode 19 may be shaped to give improved resolution of record patterns 33 likely to be of interest in the recording. Copying arrangements are described wherein the cartesian or quasi-cartesian plots of Figs. 4, 3 may be converted to polar or spiral plots and a two-electrode record/playback apparatus may be used to provide a signal delay.

Title: Improvements in or relating to connecting arrangements
Inventor: CURTIS GERALD
IPC: H04Q3/42
Filed: 1956-12-12
Abstract: 821,265. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. Nov. 26, 1957 [Dec. 12, 1956], No. 37898/56. Class 40 (4). In an arrangement for associating individual ones of a number of register-senders (hereinafter called registers) with a translator, the registers are multipled over the banks of two finders which are operative alternately, and the circuits are such that while the translator is connected with one register over one finder a connection with a second register may be prepared over the other finder. The finders FA, FB have two sets of wipers and each register appears both in the first half-bank of one set of wipers and in the second half-bank of the other set. Moreover, two translators TR1, TR2 are provided for use alternately, TR1 being effective when relay X is released and AX is operated. Assume that registers 3 and 22 are calling for a translator, relay ST being operative and wire OH earthed in each. Finder FA operates over common wire RFS and is stopped when wiper FA1 engages register 3 in position 3 by the operation of KA which connects up BA, CA, and BA locks in series with H in the register to complete the association. Relay CO energizes, and since a calling condition still exists finder FB now operates and is stopped when wiper FB2 engages register 22 in position 9 by the operation of KB, which connects up DB, X. When register 3 has received the required translation, the circuit of BA and H is opened, whereupon CB operates in place of CA and completes the associating circuit for DB in series with relay H of register 22. Relay CO falls back and disconnects AX in translator TR2. When the translation has been obtained, DB relapses followed by CB, thus preparing for the operation of ACA in TR2 which provides the next two translations. Either translator may be put out of service for maintenance purposes or by a fault by the permanent operation of X or AX, in which case all calls are dealt with by the other.

Title: Improvements in or relating to methods of riveting and tubular rivet fastenings for use therein and in tools for use therewith
Inventor: STOKES KENNETH JOHN
IPC: B21J15/06
Filed: 1964-10-03
Abstract: 1,128,442. Blind riveting. G.K.N. SCREWS & FASTENERS Ltd. 22 Nov., 1965 [3 Oct., 1964; 17 June, 1965], Nos. 40376/64 and 25636/65. Heading B3U. In a method of riveting using tubular rivet assemblies 32 the head 13 of the mandrel 31 is provided with aperturing means which enable it to pierce a hole in the workpiece prior to inserting the rivet. The head has a point 14 and is moved forwards sharply to pierce a hole in one of two sheets 16, 17, Figs. 1 and 2 (not shown) which are to be joined. The rivet then moves into the pierced hole and is held there whilst the mandrel is drawn back and the rivet set in the conventional manner. A tool for carrying out the method comprises a pair of jaws 35 which grip the mandrel 31 and an abutment 36 which bears on the end of the mandrel. Compressed air is first admitted to both of two chambers 50, 41 and the pressure acts on both sides of a free piston 39. To drive the rivet forward air pressure in the chamber 50 is released and air pressure acting on the piston within the area of a sealing lip 44 moves the piston slightly rightwards allowing the air pressure to act on the whole left-hand side of the piston which then slides rapidly along a spindle 26 and strikes a shoulder 27 driving the rivet smoothly forwards to pierce the workpiece. To retract the mandrel and set the rivet air is admitted to the chamber 50 and exhausted from the chamber 41. A perforated piston 55 entering a chamber 41 acts as a dashpot to retard the last part of the return stroke of the spindle 26.
