Patent GB-1091775-A (GB)
Title: Improvements in or relating to electrical selector circuits
Inventor: CLARK GORDON ALBERT
IPC: H03K19/177
Filed: 1965-02-18
Abstract: 1,091,775. Recording matrices. PURDY & McINTOSH ELECTRONIC DEVELOPMENTS Ltd. Feb. 18, 1966 [Feb. 18, 1965], No. 6993/65. Heading G4H. A recording circuit comprises a series of matrices having a group of column input leads x1-x6, Fig. 3, and row input leads y1-y4, the column leads being connected by diodes to a read terminal A and the row leads of each matrix being connected via diodes to an output lead B1 &c., there being capacitors to interconnect certain row and column leads, the arrangement being such that if the row and column leads corresponding to a capacitor have appropriate signals, a read signal on terminal A causes an output from the matrix on lead B. The capacitor is part of a gate circuit, Fig. 1. A negative terminal X charges the capacitor and a positive signal on terminal Y enables a pulse derived by the capacitor from the positive step signal on the read terminal A to pass through diode D2 to output terminal B. For recoding a six-bit signal to a different six-bit signal six matrices are used. Three of the input bits are recoded by Nor gates to produce a negative signal on one of eight leads and the other three input bits are recoded in Nand gates to produce a positive signal on one of eight leads. These are the column and row inputs to all the matrices. When the read pulse is applied those matrices respond which have connections between the marked column and row leads to give a new combination of six bits. Means are described for preventing the appearance of spurious pulses.

Title: Improvements in and relating to tubular rivets
IPC: B21D51/10
Filed: 1941-06-04
Abstract: 545,509. Making tubular rivets. COURTNEY, POPE AIRCRAFT, Ltd., and LYONS, C. June 4, 1941, No. 7067. [Class 83 (ii)] Tubular rivets, particularly those made from aluminium or aluminium alloys are made from strips of metal of width equal to the circumference of the rivet. The strips are cut to length suitable for skelping and are coiled, the coils if desired being annealed by heating in a small bath and quenching in a cold water tank. The strips are then skelped by passage through a die or rolls and the resulting skelps are cut to length and flanged. The rivets may be of circular, oval, or rectangular cross section.
