Title: Programme control device
IPC: G06F9/22
Filed: 1961-09-01
Abstract: 918,476. Digital electric calculating-apparatus. NATIONAL CASH REGISTER CO. Sept. 1, 1961 [Nov. 16, 1960], No. 31471/61. Class 106 (1). An arrangement for producing computer programme control signals comprises an array of transformers each having at least one secondary winding, and a selector circuit controlled by input signals so as to connect the primary winding of any desired individual transformer to a source of recurrent signals thereby to produce programme control signals on the said at least one secondary winding of the selected transformer. As described, an array of magnetic core transformers 15 is such that the transformers are normally biased by a current on a bias line passed as a single turn winding through all the cores so as to drive them to saturation. To select a particular core, signals are applied from a logical network 12 to flip-flops N1-N3 and N4-N6 whose outputs are connected to respective decoders 20, 28 which supply signals via transistor drives 22, 32 to unbias the core at the intersection of the desired column K0-K07 and row R0-R07 drive lines. Clock pulses from a source 14 are then capable of causing the selected core 15 to produce programme control pulses such as PCS1 on line 36. At the commencement of the next word interval, the flip-flops N1-N6 may be altered to select a different core 15, thereby causing the production, during the next word interval of programme control pulses the output line or lines threading the selected core. Each word interval comprises sixteen digit intervals of four pulse times each. Specification 871,386 is referred to.

Abstract: 834,441. Moulding waveguide components. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Dec. 30, 1957 [Oct. 22, 1956], No. 32073/56. Class 87(2). [Also in Groups II and XL(b)] A waveguide component is made by spraying a thin shell of metal, e.g. silver, silver cadmium alloy, zinc or tin, on to an accurately finished former the surface of which is treated to allow subsequent withdrawal of the former. A rigid metal or synthetic resin backing is applied to the thin shell. The former consists of a dismountable brass mould in the form of a tray in which cores complementary in shape to the grooves 7, 8 are mounted by means of screws or dowels. After degreasing, the former is sprayed with a thin coat of polyvinyl alcohol and then sprayed with metal to a thickness of 0À015 inch. To enable fixing holes to be drilled and tapped in the component, aluminium inserts are placed in the tray, which is then filled with a 50/50 mixture of epoxide resin and powdered aluminium. An aluminium back plate is placed on the shell over the filling, the plate having apertures to enable the resin to be puddled into the smaller cavities of the former. The former is removed after curing of the resin. Where it is necessary to provide clearance for removal of the former, this may comprise a tubular core covered with an accurately shaped layer of filled synthetic resin which may subsequently be removed by melting or by a solvent. A cooling fluid, e.g. air, may be passed through the former during formation of the component.
