Patent GB-1491047-A (GB)
Title: Self-checking data processing system
IPC: G06F11/273
Filed: 1974-12-09
Abstract: 1491047 Verifying apparatus HONEYWELL INFORMATION SYSTEMS Inc 9 Dec 1974 [10 Dec 1973 (3)] 53048/74 Heading G4A A self verifying data processing system comprises two sub-systems (preferably the control apparatus of the central processing unit and the input/output controller), each including circuitry for controlling the operation of the subsystems and exercising both sub-systems and fault detection circuitry for detecting faults during exercising. As described each sub-system is provided with a control store memory storing a set of instructions (loaded from, e.g. a cassette), a subcommand generator translating instructions into control signals and an integrity check collection apparatus identifying an error condition and transferring information to a diagnostic message register. A diagnostic direct register can also be used to examine results of signal processing. Manual data may be introduced via a maintenance panel interface. A data bus links the two sub-systems to permit transfer of data. Three modes of operation are possible (1) normal operation by the sub-system's own control centre; (2) one control centre in master state controlling the other sub-system in slave state and (3) instructions extracted from the control store of one sub-system in master state for application to both sub-systems. Testing takes place in three stages. Stage 1 (Figs. 9-10, not shown).-Segments are successfully loaded in the IOC control store, any error in loading resulting in a retry, after 10 unsuccessful retries a halt being called. Otherwise a control store scan is effected followed by internal verification of the IOC basic master logic, an error in either resulting in a master error termination. When all the segments have been loaded and no errors detected a normal termination is effected. A similar process is then effected on the CPU. Stage 2 (Figs. 11-14, not shown).-Segments are again loaded into the IOC control store and providing no load or scan errors occur the IOC diagnoses the CPU master and extended master apparatus (which includes the control store array, control store addressing logic, main adder and verification apparatus), the control store of the CPU being successively loaded with segments, a halt being called if loading after retries is still unsuccessful and a IOC slave-error terminate occurring if a CPU error is found. The CPU then tests the IOC master in a similar manner. The CPU non-master apparatus (logic circuitry) is then tested by the IOC master apparatus followed by testing of the IOC non- master apparatus by the CPU master. Stage 3 (Figs. 15-17, not shown).-The CPU control store is again loaded and provided no loading or scan errors are detected the main memory diagnosis is effected. This is followed by testing of the buffer store. Finally the CPU/ IOC interactive apparatus is tested, the CPU and IOC acting under the control of the CPU.

Title: Selective Printer with Movable Platen.
Inventor: GRAY ALBERT
IPC: B41J11/20
Filed: 1968-11-12
Abstract: 1,188,920. Selective printing. INTERNATIONAL BUSINESS MACHINES CORP. 12 Nov., 1968 [20 Dec., 1967], No. 53516/68. Heading B6F. A selective printer comprises a platen 18, a type carrier 12 including a plurality of type elements (17), Fig. 2, not shown, for printing on a document 16, the type carrier 12 being movable about a pivot 15 between an open position for insertion of a document and a closed position for printing, and locking means locking the type carrier in the closed position and simultaneously moving the platen 18 towards the type carrier 12. The locking means comprises a handle 42 formed with a hook 48 for engagement with a pin 50 of a latch member 51, the handle 42 being pivotable on a shaft 38 and being connected by a spring 44 to a selector 40 fixed to the shaft 38. Upward locking movement of the handle 42 causes rotation of the shaft 38 through the spring 44, an eccentric 36 thereby being rotated to urge the plates 18 against springs 30 towards the type carrier 12. When a sensing member 68 strikes the document 16, a latch lever 64 carrying the sensing member is rotated to allow a latch lever 60 to pivot under the bias of a spring 62 and bring a pawl 50 into locking engagement with teeth 43 on the selector 40. The position of the platen 18 is thereby controlled by the thickness of the document 16. Lowering of the handle 42 to the latch releasing position shown brings a pin 46 into contact with the cam 40 to rotate the eccentric 36 to a position wherein the platen is at its furthest point from the type carrier 12.

Title: A direct current apparatus having a superconductive coil
IPC: H02K55/00
Filed: 1965-12-17
Abstract: 1,126,968. Dynamo-electric machines; rectifiers. SIEMENS-SCKUCKERTWERKE A.G. 17 Dec., 1965 [18 Dec., 1964; 1 April, 1965; 15 April, 1965], No. 53723/65. Headings H2A and H2F. Commutation in a superconducting D.C. machine or A.C. to D.C. converter is achieved by making each armature coil partly of a material having a sufficiently low critical field to be rendered normal by the working field of the machine so that each coil is rendered alternately resistive and superconductive by the passage of the field which generates the induced E.M.F. As shown, sections 11 of armature coils 2, 3, 4 and 5, are sequentially made normal by the pole flux to prevent reverse flow of current from the active coils through the bus-bars 6, 7. By this means, the negative half-cycles are suppressed. The sections 11 may (Figs. 2a, 2b, not shown) be on opposite sides of a single coil having two turns. These turns may be spaced by one pole-pitch (Fig. 4, not shown), and the leads 6, 7 may be at opposite ends of the machine (Fig. 5, not shown). The coils may extend over axially spaced poles which are staggered and of opposite polarity (Fig. 6, not shown). A single coil may be arranged to carry current in both directions (Figs. 7, 8, 9, not shown), by providing it with two circumferentially spaced parallel connected switching paths 11 which operate alternately. Each coil may have several turns, and it is described in Fig. 11 (not shown), how superconductive layers (18) may lie between plastics layers (19) and between copper foils (17) which act as the switching paths. The machine may be of cylindrical or planar air-gap type (Figs. 12, 13, not shown) and special commutating poles may be provided to give loss-free commutation (Figs. 14-18, not shown). Commutating voltage may be injected by self-saturating chokes on each coil (Figs. 20, 21, not shown), A rotating-field converter is shown in Fig. 22. The switching paths may be superconductors such as lead, niobium, or alloys of lead-bismith, niobium-tantalum or molybdenum-rhenium, and one less than 10<SP>-5</SP> cm. thick. The rest of the windings are of alloys which remain superconductive in the working field such as niobiumzirconium, titanium-niobium, niobium-tin, or vanadium-gallium.

Title: Improvements in and relating to cassette changers
IPC: G11B15/44
Filed: 1970-11-12
Abstract: 1292524 Cassette machines AMPEX CORP 12 Nov 1970 [19 Nov 1969] 53922/70 Heading G5R Two tracks recorded in opposite directions on a cassette tape 21 may be played sequentially or selectively using a reversible drive system and tape motion sensor. With switches 5 and 7 arranged as shown, a motor M drives a capstan 27 and pinch roller 31 for "forward" tape movement and when the reel 17 is unwound a motion sensor 37 detects lack of movement of spindle 22 and energizes a solenoid 35 to cause a reversing system 33 to change the motor drive to capstan 25 and pinch roller 29. The tape then moves in the "reverse" direction to allow the second track to be played and on completion the sensing means 37 energizes a cassette ejection system 39. If contact 53 of switch 7 is moved to contact 65, the cassette is ejected after playing only the "forward track" because the reversal of the capstan drive causes a linked switch 11 to change and so leaves the motor M on open circuit, cessation of rotation of spindle 22 again being sensed 37 to cause the ejection. If contact 49 of switch 5 is moved to contact 61 and 53 of 7 retained at 51, the system immediately "reverses" because "forward" movement is not possible. The switch 11 is thus changed to 59 and the reverse track is played and, when completed, ejection occurs.

The cam-wheel. Fig. 8, comprises two long teeth 32, 33, two short teeth 34, 35 and two cam walls 36, 37 separated by a slot 38. The pin 39 may pass through slot 38 when the cam-wheel is in the position shown or be driven by either cam wall when the cam-wheel is in the position illustrated in Figs. 9 and 10 (both not shown). The pawl lever 40 has a cam 43 engageable by the nose of a pivotally-mounted trigger 45. The stroke of the trigger is limited by an axially-movable spring-loaded pushbutton 47 provided with a cut-out 49. Another spring-loaded push-button 50, Fig. 2, has a stem 51 which, when the button is pressed, abuts the back of trigger 45 and forces it into such position, Fig. 10, where finger 41 does not contact the teeth of cam-wheel 31 so that the cutting operation is continuous. At the same time, an abutment of push-button 50 operates a reversing microswitch 52. The pinking blades may be replaced by scalloping shear blades (53), Fig. 5 (not shown), scissors blades (54), Fig. 6 (not shown) or metal snips (55), Fig. 7 (not shown).

Filed: 1970-11-13
Abstract: 1331645 Punching K KONDO 13 Nov 1970 [15 Nov 1969] 54202/70 Heading B3W In a precision shearing method which uses a punch and a die, of which one is of conventional design and the other is stepped to form clearances relative to said one tool which are positive, and negative or substantially zero, one of the tools is urged towards the work thereby causing first the positive, and then the negative or substantially zero, clearance to act on a workpiece, the process being completed without allowing the punch to enter the die to a distance greater than the height of the stepped portion. For blanking of discs from a plate the step 6 is formed on the punch; for punching, the step is on the die. Instead of the right-angled step shown the step may be inclined to the stepped position at 45 degrees. The step need not be continuous but may be provided only at sharp cornered convex parts where fracture cracks would be likely to develop. The stepped punch or die may be used in combination with conventional fine blanking techniques of clamping a workpiece around the cut using a knife edge on a pressure plate and rounding the tool edges.
