Processor A controls the gates in the computing system, processor B controls the stores in the computing system, processor C controls masking and processor D controls the arithmetic and logic unit. Processor E in conjunction with an associative store F carries out tests, for example to identify predetermined conditions during multiplication or division, or to detect errors or an interrupt; associative store F receives address signal inputs EWF from processor E and RWF from the computing system. Microprogram store M receives address signal inputs FWM from associative store F and RWM from the computing system. Each of the processors A-E includes a writable, non-destructive readout data store (10, Fig. 2, not shown). The initial address for readout from the store (10) is entered from microprogram store M into an address register (13) and subsequent addresses are obtained by reentering the initial address unchanged or via an incrementing loop (25, 26) as determined by a control bit in the latest word read-out of the store (10). Thus if successive control bits are "0" successive addresses are accessed, but a return to the original address occurs on detection of a "1" control bit. When a new starting address is to be used a control signal is supplied to an input address register (21) and to an output register (12) to clear these registers.

Abstract: 1490226 Transistor signal gating circuits SIEMENS AG 5 Dec 1974 [10 Dec 1973] 52572/74 Heading H3T In a transistor signal gating circuit in which a common input E is connected to outputs Al- An via output arms 1-n each comprising a two-stage A.C. signal amplifier with a common base transistor input stage TS1 and a common collector transistor output stage TS2, the emitter-collector path of the transistors TS1 and TS2 is connected in a series D.C. path between two supply voltage terminals, the base of each transistor TS1 is connected via a respective choke D1 to the emitter of a further common collector transistor stage TS3 which serves to maintain the potential at the base of each transistor TS1 constant and a respective control terminal St1-Stn is connected to the collector of each transistor TS2 to enable or disable the associated signal arm 1-n. Earth potential is applied to the relevant control terminal St1-Stn to enable a signal to pass the associated arm 1-n. When an output arm is blocked by removal of the earth potential from the control terminal the output transistor TS2 turns off but the emitter current of the associated input transistor TS 1 is practically unchanged due to the transistor TS3 which keeps the base voltage of TS1 constant. The transistor TS1 is saturated and therefore no longer has an amplifying function. As the emitter current is maintained the input impedance of the amplifier remains virtually unaltered.
Patent GB-531690-A (GB)
Abstract: 531,690. Roof and floor surfacing. STEVENS, A. H. (Celotex Corporation). July 4, 1939, No. 19451. Drawings to Specification. [Classes 20 (iv) and 107] [Also in Group VIII] A surfacing construction for roof decks, floors, and the like, e.g. of concrete, consists of a covering comprising a number of units of felted fibreboard laid in edge-to-edge relation, the units having interstices which are incompletely filled with bituminous material. The fibreboard material is made from a relatively coarse cellulose containing fibre stock which may be derived from cotton, sugar cane, bagasse, liquorice root, corn stalks, &c. These fibres are suspended in water and then filtered therefrom by a screen on which they are deposited as a sheet formed of a plurality of superposed and interlaced layers. This sheet is then impregnated with an asphalt which will soften at about 90‹F. to 170‹F., and the partial impregnation desired may be obtained by using asphalt to the extent of 1.8 to 2.5 times the weight of the fibre. The units may be applied on a bituminous layer which covers a waterproof membrane made up of a number of pieces of tarred felt. The units may be pressed into the bituminous layer while the latter is still hot so that some bitumen will be squeezed into the joints ; alternatively, the joints may be filled subsequently with bitumen. After application of the units, coats of bituminous material or coloured asphalt paints may be applied to their surfaces, and, if desired, a final coat of aluminium paint. The tarred felt membrane may be turned up at its edge adjacent a parapet wall under a downwardly-extending metal flashing.

Filed: 1971-11-22
Abstract: 1370379 Logic circuits INTERNATIONAL BUSINESS MACHINES CORP 22 Nov 1971 [23 March 1971] 54060/71 Heading H3P An exclusive OR function is performed on so-called "morphic variable pairs" A, B to give an output morphic variable pair X. The two binary variables 1, 2 and 3, 4 Fig. 1 constituting each pair are different (01, or 10) to represent one data condition called Code Space, and are similar (00 or 11) for the second data condition called Error Space. The two simple exclusive OR gates of Fig. 1, each receive one variable from each of the morphic variable pairs A, B, namely 1, 3 and 2, 4, and the output X is so-called Code Space provided that one and only one of the pairs A, B is Code Space; the output X is otherwise Error Space. The detailed construction of Fig. 1 (Fig. 3, not shown) has each simple exclusive OR gate formed of two AND's each receiving one of the variables (e.g. 1, 3) in tone form and the other (3, 1) in inverted form; and an OR gate receives the AND gate outputs to provide the respective variables of the output morphic variable pair X. In another embodiment (Fig. 2, not shown) one simple exclusive OR circuit receives the variables 1, 3 while the second exclusive OR circuit receives the variable 2 and the output of the first exclusive OR circuit, the morphic output consisting of the output of the second exclusive OR and the fourth input variable 4. Trees of morphic exclusive OR circuits are disclosed (Figs. 5, 6, not shown). It is said that the circuits are selftesting in that whenever a failure occurs in the circuit, at least one pattern of input information will produce an erroneous output to indicate the failure, and the masking of a failure by an accidentally correct output is prevented. Combinations with so-called morphic AND circuits are mentioned.

Abstract: 1482641 Television EMI Ltd 12 Nov 1974 [22 Nov 1973] 54283/73 Heading H4F Picture disturbance resulting from a faulty detector or unbalanced detector output in an array of ten detectors 5, Fig. 1, in an infra-red scanner, is distributed over the display by arranging for the picture information of corresponding lines of the display in consecutive frames, to be derived from different detectors in the array 5. Radiation enters the scanner via window 1 and is reflected by a rotating mirror drum 3 and an oscillating mirror 4 on to the array 5. The drum 3 provides the horizontal scan and mirror 4 the vertical scan. The ten detector outputs, each representing one strip of picture, are amplified, A-D converted, and applied by a commutating device, in block 6 to a ten line store 8 or 9. Simultaneously the previous ten lines of information which will have been applied to ten line store 9 or 8 respectively are read out, D-A converted, and applied to a display device 11. A timing circuit 7 controls the operation of each stage, more especially it controls the movement of the drum 3 and mirror 4 so that drum 3 effects 62À9 sweeps per frame, yielding 629 lines of information of which four are rejected, and mirror 4 oscillates at the field rate. Fig. 3 indicates the manner in which the origin of the picture signal for each line changes between consecutive frames under this arrangement. Stores 8 and 9 may comprise digital shift registers or charge transport devices, in the latter case the D-A converters may be omitted. A signal multiplexing arrangement may be utilized prior to the A-D converter in block 6. Ten detectors may be employed for each line yielding a 10 Î 10 matrix thereof.

Abstract: 1368120 Optimizing processes BAGGERMAATSCHAPPIJ BOS & KALIS BV 29 Nov 1971 [1 Dec 1970] 55350/71 Heading G4G Apparatus for determining the optimum loaded condition of a carrier which is loaded at a decreasing rate as the rate increases, comprises means for measuring the instant load for forming the quotient of the load and the time elapsed since the commencement of the loading cycle, and means for indicating when the rate of change of this quotient is zero. In the case of a hopper barge, the rate of loading decreases when the hold overflows with loss of solid material. At a time F (Fig. 2), the weight of solid/water mixture in the hold exceeds the weight of water in a water-filled hold. At time B, the hold starts to overflow, and at time C, the loading is terminated. The time-elapse between C and A (or A<SP>1</SP>) represents discharge and travel time to and from the discharge site. The zero of the time cycle, from which T is measured is C (or C<SP>1</SP>), and the " production " cycle starts at F when the useful load just exceeds zero. A pneumatic draughtmeter generates an air pressure proportional to hydrostatic pressure at a point on the hull below water line. This is converted to an electric signal which is compared with a fixed voltage proportional to a (Fig. 1) to yield a useful load signal L. A time-proportional voltage generator provides a signal T and a quotient generator provides a signal L/T which is fed to a recorder observed by the skipper. The optimum loading condition is reached when the recorder indicates that d/dt(L/T)=0.

Abstract: 1,248,412. Respiratory appliances. ROBERTSHAW CONTROLS CO. 22 Nov., 1968 [24 Nov., 1967], No. 55601/68. Heading AST. An oxygen-air diluter for breathing apparatus comprises an oxygen inlet 12, an air inlet 64, an outlet 14 to the user, a variable flow nozzle 18 delivering a jet of oxygen into a venturi 22 and entraining air with it, said nozzle having a movable valve member 24 controlled by means responsive to demand at the outlet. Air inlet from the atmosphere is controlled by a flexible valve disc 56, the maximum extent of opening of the valve 56 being limited by an aneroid bellows 52, in response to atmospheric pressure. The means controlling the valve member 24 comprises a flexible diaphragm 26, with a bleed port 28, and exposed on one side to the inlet oxygen, and on the other to a bleed chamber 30 which has an orifice 32 controlled by a flapper valve 34 such that when the orifice 32 is open oxygen leaves the bleed chamber 30 faster than it enters through the bleed port 28, creating a pressure difference across the diaphragm 26 which moves valve member 24 up to allow oxygen to flow through the nozzle. Pressure at the outlet is communicated by a port 45 to a chamber 36 on one side of a diaphragm 44, the other side of which is exposed to the atmosphere through a port 49. Diaphragm 44 has a button 38 fixed to its centre. When the user breathes in the pressure drops in chamber 36 forcing diaphragm 44 down so that button 38 actuates the flapper valve, and hence the valve member 24 rises. Air enters through slots 64 in a cylindrical wall of a housing 60. An aneroid bellows is mounted on the atmospheric side of diaphragm 44 such that its movable end abuts on the centre of diaphragm 44 so that as atmospheric pressure drops the diaphragm is pressed down to increase the amount of oxygen delivered.
