Title: Data processing machines
IPC: G06F11/07
Filed: 1969-10-02
Abstract: 1,247,746. Data processing. INTERNATIONAL BUSINESS MACHINES CORP. 2 Oct., 1969 [30 Oct., 1968], No. 48405/69. Heading G4A. A data processing machine includes a plurality of functional units capable of co-operating in a plurality of configurations in order to execute a programme, control means for determining from an examination of the current control word for each machine cycle the appropriate configuration of functional units to be operational (involved in the execution of the programme), test means for inserting, during a machine cycle, a test pattern into a non- operational functional unit, and error detecting means for detecting malfunction of the tested functional unit in relation to the test pattern and means for forcing a predetermined routine on the machine in response to such detection. In a microprogramme-controlled machine having a parallel adder, if the current microinstruction indicates that the adder is not required in the current cycle, two test words from registers are inserted into the adder and if an error is detected at the adder the machine is caused to wait and the test words are applied again. If an error is still detected an error routine is entered but if not the machine proceeds. If the adder is required in a given cycle, and an error is detected at it, the error routine is entered. Similar provisions can be made for other functional units, the same microinstruction indicating if they are required in the cycle or not. Errors detected as a result of application of test words are counted in a counter common to all the testable functional units (or separate counters could be provided) to indicate system reliability: the counter output can be used to enter a test routine to provide further information about system reliability. The number of reapplications of the test words before the error routine is entered could be more than one. Other possible functional units mentioned are a register and a data bus. A redundant functional unit coud take over the workload of a defective functional unit. The test patterns used are dependent on the functions to be tested and their past history.

Title: Speed Indicator.
Inventor: PELTA EDMOND RAPHAEL
IPC: G01P1/10
Filed: 1967-11-03
Abstract: 1,185,348. Measuring rotational speed, electrically. AUTOSCAN Inc. Nov. 3, 1967 [Jan. 10, 1967], No. 50072/67. Heading G1N. A system for providing an aural and visual indication of the rotational speed of a shaft, e.g. of an I.C. engine, particularly its deviation from a required value, comprises a tachometer 10 Fig. 1 which produces a D. C. voltage dependent upon the actual speed S, an adjustable D.C. source 15 to provide a voltage R representing a required speed, and an oscillator 12 and integrator 13 to provide a sawtooth wave 13a having a voltage difference 2E between maximum and minimum peaks which is added to the actual speed signal S. The sum signal S + 2E is applied to one input of a differential amplifier 14 while signal R is applied to the other input. The amplifier output is a series of rectangular pulses the mark/space ratio of which varies with the rotational speed S, as indicated, in Fig. 2, and the output operates a buzzer 18 and lamp 17. It is arranged that when R = S + E the duration of a pulse equals the duration of a pause between pulses, which condition can readily be detected for example by a mechanic adjusting an engine component B Fig. 1, signifying that the engine is running at the required speed. The maximum to minimum peak difference 2E can be adjusted to set the speed range within which intermittent pulses are produced and the lamp and buzzer operative. That is, the range limits can be voltage R = voltage S and R = S + E2, the value 2E corresponding to the speed differential e.g. 300 RPM where desired speed is 2500 RPM. The tachometer may be connected to receive engine ignition pulses. Alternatively the amplifier output may be connected to trigger two buzzers, one to sound at one end of the speed range and the other to sound at the other end.

Abstract: 1481204 Wrapping blocks of cigarettes GD SpA 20 Nov 1974 [21 Nov 1973] 50274/74 Heading B8C A cigarette packeting machine comprises intermittently rotatable wrapping heads 1-4 each having a plurality of radially accessible compartments Z for receiving blocks of cigarettes, grippers 10a, 11a, 12a, 13a and 14a, 15a for transferring unwrapped or partially wrapped cigarette blocks between the wrapping heads 1-4 and plate members 26, 40, 43 which move temporarily between the cigarette blocks and the wrapping material X, X1 to act as supports against which the wrapping material is folded. The grippers 10a, 11a, 12a, 13a, 14a, 15a are carried on pivotally mounted levers 10-15 which are oscillated by cams 1-9. Respective plate members 26, 40, 43 are associated with each compartment Z of the wrapping heads 2, 3 and 4. In operation a block of cigarettes is pushed from a packet conveyer 22 into a compartment of the wrapping head 1 from which it is subsequently removed at a station IZ3 and transferred with an inner wrapper X into a compartment of the wrapping head 2 by the grippers 10a, 11a. This transfer causes the wrapper X to be U-folded about the block of cigarettes. A pair of jaws 25 then close and position plate members 26 which are carried thereby, between the arms of the U-folded wrapper so that upon movement of the cigarette block to a station IIZ3 the arms of the U-folded wrapper are folded against the plate members by an oscillatory folder 28 and a stationary guide 29. At the station IIZ3, the plate members 26 having been withdrawn, the ends of the wrapper X are folded in by oscillatory folders 30, 31 and 32. At a further station IIZ5 the block of cigarettes enclosed in the inner wrapper X is transferred with an outer wrapper X1 into a compartment of the wrapping head 3 by the grippers 12a, 13a. This transfer causes the wrapper X1 to be U-folded about the inner wrapped block of cigarettes while an edge portion of the wrapper X1 is folded against one end of said wrapped cigarette block by a projecting folding member 39. A plate member 40 which forms part of a horizontally reciprocable unit 38, is then positioned between the arms of the U-folded wrapper X1 so that a vertically reciprocable folding finger 36 and a stationary guide 41 can fold said arms against the plate member 40. The plate member 40 is withdrawn as the thus partially formed packet is moved to a station IIIZ5 whereat it is transferred by the grippers 14a, 15a to a compartment in the wrapping head 4. During this transfer a projection 42 folds a further edge portion of the wrapper X1 against said one end of the inner wrapped block of cigarettes. An oscillatable folder 44 at a station IVZ3 and a stationary folder 45 then complete the folding of the wrapper X1 by folding flaps over a plate member 43 positioned against said one end of the wrapped cigarette block. At a station IVZu the wrapped cigarette block is pushed from the wrapping head 4, past a revenue stamp applicator member 49 and on to a discharge conveyer.

Abstract: 1,124,018. Fuel efficiency meter. SANDALL PRECISION CO. Ltd. Dec.10, 1965 [Dec.18, 1964], No.51512/64. Headings G1K and G1R. A fuel efficiency meter for a vehicle comprises a positive-displacement liquid meter, Fig. 1, generating a signal for each unit volume of fuel passing therethrough, measuring mechanism, Fig. 5, to determine the distance travelled in each interval between successive signals generated by the meter and a pointer 54 indicating the fuel efficiency in miles per gallon for the preceding interval. The liquid meter comprises a cylinder 4 whose ends are attached by rolling diaphragms 5, 6 to a hollow light alloy body 1, 2, 3 to provide two closed spaces 7, 8 each having a swept volume of 6¥ cubic inches giving a total of 1/20 of a gallon. Each time one end or the other of a slot 9 in the cylinder 4 rocks a lever 11 it actuates a micro-switch 13 to turn a valve 24 through a right-angle so that a fuel from a pump entering a conduit 20 passes through a conduit 22 to the carburettor alternately through conduits 25, 23, spaces 8, 7, conduits 21, 26 and conduits 25, 21, spaces 7, 8, conduits 23, 26 at the same time causing the reciprocating motion of the cylinder 4. The ends of another slot 10 rock a lever 14 carrying a portion 18 pivoted thereon and biased,by a hair spring so as to actuate two micro-switches 17, 16 sequentially when moving in one direction and neither when moving in the other direction. In a modification the conduit 22 is connected to a fuel injection device, the fuel is supplied at higher pressure and the member 4 is dimensioned to constitute a piston and may carry piston rings. The efficiency indicator comprises a spindle carrying the pointer 54 and a brake drum 58 locked by a shoe 55 on the armature 56 of an electromagnet 57. A second spindle 47 is connected to the drum 58 by a spiral spring 53, is biased toward a stop 50 by another spiral spring 48 and carries a wheel 46. The armature 42 of another electromagnet 43 carries a bearing 41 for a speedometer driven shaft 40 and so long as both magnets 57, 43 are energized the frictional coupling between shaft 40 and wheel 46 drives the spindle 47 and stresses the spring 53. At the end of the consumation of each 1/20 gallon the micro-switches 17, 16 are actuated and sequentially de-energize the magnets 57, 43. Thus the pointer 54 assumes a position indicating the miles per gallon over the interval just completed and the spindle 47 returns to its initial position. The micro-switch 17 also actuates a counter to register the total volume of fuel consumed.
