Title: Improvements in electric switches
Inventor: POPLE ARTHUR JOHN
IPC: H01H19/56
Filed: 1962-05-11
Abstract: 983,433. Rotary distributers. BRISTOL AIRCRAFT Ltd. Aug. 12, 1963 [May 11, 1962], No. 18220/62. Heading H2B. An electric switch comprises a plurality of switch units, each comprising two discs 20 and two rings 29. The discs are formed so as to be mounted on a splined shaft 16 and each has a periphery part of which is conducting and part of which is non-conducting. Each ring is made of non-conducting material, is formed with holes 30 therein, is mounted on longitudinal rods 31 extending through some of the holes and carries a contact 32. The two discs of a switch unit are mounted so that the parts of their peripheries which are conducting are in contact and as the shaft 16 rotates a circuit is made between the contacts 32 of the two rings of a switch unit when these two contacts are both in engagement with the conducting parts of their associated discs. The point at which the circuit is made relative to the angular position of the shaft 16 can be adjusted by altering the angular position of the discs 20 with respect to a datum on the shaft and/or by mounting the rings 29 on the rods 31 through other of the holes 30. The length of time during which the circuit is made or broken is altered by suitably offsetting a pair of identical discs and by providing a set of pairs of identical discs so that a full range of durations of circuit make positions can be obtained. Each switch unit is insulated from the next by a disc of insulating material 24, 25, 26 and from the shaft by forming each disc 20 with an annulus of insulating material.

Title: Improvements in or relating to data processing systems
IPC: G06F7/50
Filed: 1966-05-02
Abstract: 1,142,465. Data processors. INTERNATIONAL BUSINESS MACHINES CORP. 2 May, 1966 [12 May, 1965], No. 19173/66. Heading G4A. In a data processing system, access to an address in peripheral storage is permitted or prevented in accordance with the result of a comparison of the address with information developed from a stored catalogue of addresses available to the current programme. A CPU (central processing unit) with associated main core storage can communicate via channels with external devices viz. input/output units and storage units (e.g. disc units). A stored catalogue, in the main storage or an external storage unit, specifies for each data file in an external storage unit, the boundaries of the file (high and low, cylinder and head numbers in the case of a disc unit) and the types of writing and reading access permitted to the associated problem programme. Other problem programmes are denied all access. The control unit of an external storage unit, on being selected for storage access, receives the relevant information from the catalogue byte by byte, the bytes being passed on respective odd counts of a counter in the control unit, from an in - put/output register which initially receives them, to respective further registers in the control unit. The access attempt is terminated and the CPU interrupted and informed of the reason, if the input/output register does not hold zero on any even count, during this. In the absence of this error indication, the cylinder and head numbers of the desired address are received into the input/output register in turn and compared with the boundary bytes in turn, under control of the counter, in the following order (disc unit): cylinder high, cylinder low, head high, head low. The required cylinder and head are selected as soon as their respective comparisons say yes, but if any comparison says no, the access attempt is terminated without further comparisons and the CPU interrupted as before. Termination &c. will also occur if the access is of a non-permitted type, as determined in the control unit, or if the input/output register does not hold zero at certain times before and after the comparisons. Cylinder selection involves finding the difference between the present and desired cylinder numbers, in an adder. A circuit is provided to detect any attempt to set said further registers with more than one set of information from the catalogue. In a modification mentioned, the catalogue supplies two bits specifically allowing or forbidding movement from the current head and cylinder respectively, instead of the boundary data. Conventional arrangements for selection of an external device, including transmission of status back, are described.

Abstract: 721,026. Semi-conductor devices; removing metal electrolytically. STANDARD TELEPHONES & CABLES, Ltd. July 10, 1953 [Aug. 1, 1952], No. 19225/53. Classes 37 and 41. In a process for the external shaping of a semi-conducting device comprising both N and P materials, by electrolytic etching, use is made of the rectifying effect of the interface between materials of different conductivity types. As shown, an N-P-N block Z<SP>1</SP>, Z<SP>2</SP>, Z<SP>3</SP> is immersed in an electrolytic etching bath, e.g. glycolester, so that only one end, which forms the anode, partly protrudes, the cathode K being immersed in the bath and surrounding the block. Electrical connections are such that current is blocked by the upper rectifying interface, so that material is dissolved from the upper block Z<SP>1</SP>, particularly near the interface, but not from the layer Z<SP>2</SP>. The block is then inverted and connection made to block Z<SP>3</SP> to dissolve material at the other interface leaving a large surface on layer Z<SP>2</SP> on which to fix an electrode. Alternatively positive connections are made to both ends and the block wholly immersed. If the direction of rectification at the interfaces is reversed a different electrolyte is used to give cathodic etching.

Abstract: 1304461 Cathode-ray tube displays RCA CORPORATION 22 April 1970 [30 April 1969] 19352/70 Heading H4T In a display system utilizing a plurality of cathode-ray tubes D1-D14 (Fig. 11), on which displays, which may be different, are produced by ON-OFF beam control of a conventional television line-raster, seven memories A-G, each including a delay line 300 (Fig. 10) are provided each supplying coded character data for two of the displays via OR gates 312, 314 to a first character generator CG1 and via serially connected shift registers SR1a, SR1b- SR12a, SR12b to respective character generators CG2-CG13. The outputs of the latter (the ON-OFF beam control signals) are then supplied via a switching network 316 to the displays D1-D14 in such fashion that each character generator is time shared by all of the displays. Fig. 15, shows portion of one of the displays each of which displays 16 rows each of 16 characters. Each row occupies 28 interlaced television scan lines and switching network 316 operates such that character generator CG1 supplies the character information appropriate to the first line in the first row of characters on the displays D1 to D14 during respective successive line scans whilst character generator CG2 supplies the information corresponding to the third line in the first row on D1 to D14 and character generator CG3 the information corresponding to the fifth line in the first row on D1 to D14 the operation continuing in this order until the information for the twentyfifth line has been supplied to the displays D1 to D4 after which the cycle is repeated in respect of the even numbered lines in each row and further in respect of each of the 16 rows of characters. Each character generator commences to supply its information during (13) successive line scan periods and to prevent the same character line on each display occupying a different vertical position, the vertical retrace of each display may be suitably staggered or, if a minor variation in the vertical positions is acceptable, the vertical retrace may be staggered only for groups of displays. The whole system is synchronized from a source 28, Fig. 1 (e.g. a 60 CPS power line) to which the displays are also synchronized and this arrangement allows the delay line 24 (300, Fig. 10) to be of a simple nature. The whole of the operation is described with reference to logic circuit diagrams and timing waveforms.
