Title: Improvements in digital electric calculating apparatus
Inventor: OWEN CHARLES EDWARD
IPC: G06F9/26
Filed: 1961-02-15
Abstract: 988,085. Programming arrangements for computers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 15, 1962 [Feb. 15, 1961], No. 5572/61. Drawings to Specification. Heading G4A. In a digital electric calculator which comprises a number of registers each operable under the control of timing impulses to receive data on a set of common drive lines and to make data available on a set of common sense lines at predetermined times in the cycle of operation, the selected lines of the set of sense lines are shared by a control matrix itself operable under control of the timing impulses to deliver data to the sense lines, and the latter are connected to temporary storage means operable to transfer information carried by the sense lines to the drive lines. The invention is primarily concerned with microprogramming. A microprogram usually consists of the sense lines threading a column of cores of the control matrix, and it is necessary to increment only a so-called y-address at each step of the microprogram to select the next control core. This is done automatically by the means described in Specification 981,780. Changing the x-address requires a special micro-order. A description is given of the operation of the control system in a small digital computor having a keyboard data entry, and a typewriter for program tape input and for output. The arithmetic unit consists of a subtractor matrix working to radix 12. There is a main core store having yaddress registers A, B, a working store having y-address registers, P, Q together with single respective x-address registers, an arithmetic register T and a set of condition cores an appropriate one of which is set when a specific condition (negative signa, over flow &c. exists. The P.Q. registers are also arithmetic registers. There is described in some detail with reference to Figs. 1 to 6 (not shown) a 21-point operating cycle for each microinstruction in which the following operations are carried out: 1. Store to register, or register to store,transfer. 2. Subtract P or Q from arithmetic register T. Result to T. 3. Load constant into P or Q. 4. Select next microinstruction, with or without conditional branching. The subtraction matrix consists of an array of magnetic cores the row and column selection lines representing the operands and sense lines threading those cores at the intersection of selection lines representing numbers having the same difference (Fig. 7 not shown). A microprogram is initiated from the input program tape which carries the address of the first control core.

Title: A Demodulator for a Multivalent Telegraphic Signal
IPC: H04L27/14
Filed: 1968-02-05
Abstract: 1,175,801. Digital transmission systems. C.I.T.-COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 5 Feb., 1968 [17 Feb., 1967], No. 5635/68. Heading H4P. Multifrequency digital data is converted to the corresponding binary data by a receiver employing a number of auto-correlators. In the case of 4-level data, in which each frequency F1-F4. represents a unique pair of bits, 4 correlators 20, 60 are used. In the received signals X transition from one frequency level to another takes place over the duration of a signal element. The instantaneous frequency at the significant instants is here called the transition frequency. The received data X passes to 3 correlators 20. Each comprises a multiplying circuit (EXCL. OR) fed by the data both direct and via a half element delay, the multiplier feeding a low-pass filter. The resulting amplitude-varying signal b, c, d passes to a limiter, each unit 20 having its limiter set to a different level corresponding to a transition frequency F 12 , F 23 , or F 34 . The limited signals b<SP>1</SP>, c<SP>1</SP>, d<SP>1</SP> feed stores 30 and also unit 80 (not described) which converts the signals to the binary data W. Clock pulses e are fed to unit 80, being derived from the data as described below. Each store 30 is a 2-cell shift register; one cell indicates whether the frequency at the instant of read-in to the register is above or below the chopping level of the associated limiter, and the other cell indicates the frequency at the preceding read-in instant i.e. one element period earlier. The outputs of the first cells are thus as f, f<SP>1</SP>, f<SP>11</SP> and of the second cells as h, h<SP>1</SP>, h<SP>11</SP>. From these outputs an arrangement of gates 40, Fig. 7 (not shown), determines the transition frequencies (line j) there being 5 possible frequencies. Unit 40 varies the chopping level Z of limiter 50 in accordance with the transition frequencies, the signal m to be limited coming from a fourth correlator 60. The resulting signal p passes to a circuit 73 fed by clock pulses e from gate 72. Unit 71 gives clock pulses at greater than element rate, which are divided by counter 72, the phase of the counter being controlled by the output q of circuit 73 so that the clock pulses are synchronized with the data.

Title: Improvements in electron beam tube arrangements
IPC: H01J25/78
Filed: 1941-05-02
Abstract: 583,024. High frequency discharge apparatus. STANDARD TELEPHONES & CABLES, Ltd., and TOMLIN, S. G. May 2, 1941, No. 5718. [Class 39 (i)] A beam of electrons is modulated by a variable magnetic field before giving up energy to a resonator. In one form, a Lecher wire input system LW, Fig. 1, is terminated at a current antinode by a wire which is parallel and close to the beam B. The magnetic field of the wire deflects the beam across an opening S in a coaxial line or other type of rhumbatron R. The beam may strike opening S either once or twice per cycle, for amplification and frequency doubling respectively. In another form, a hollow toroidal input resonator RI, Fig. 2, is bounded by concentric cylinders E1, E2 and end discs F1, F2 and is so excited that the magnetic field has maxima of intensity near E1 and E2. A number of holes D, Fig. 3, are made near E1 and an annular beam B is fired through them. The magnetic field of resonator RI gives a variable conical shape to the beam which permits it to enter an energyextracting gap G in toroidal output resonator R2. The transit time through holes D is small compared with a cycle of oscillation. The resonators R1, R2 may be coupled together.

Abstract: 1,221,954. Gas turbine engines. REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT. Feb.5, 1968 [Feb.17, 1967], No.5752/68. Heading F1G. A gas turbine engine comprises compressor, combustion chamber and turbine, means being provided for causing intermittent operations of the combustion chamber and for the delivery to the turbine of alternately combustion gases and cooling or scavenging air. The engine in Fig. 1 comprises compressor 2 of the radial flow type, combustion chamber 8 and turbine 3, 4 connected to drive compressor 2 also an external drive shaft 14 through suitable gearing. A duct 15 open to atmospheric air is connected to the duct between the combustion chamber and the turbine, a rotary valve assembly 16 being provided which opens the combustion chamber outlet and the atmospheric air duct 15 in sequence. The compressor supplies air continuously into the combustion chamber but fuel is supplied intermittently thereto through the Diesel engine type fuel pump 22 and injector 9. As shown, the combustion chamber outlet is open and gases are discharging on to the turbine. At a later point in the cycle the combustion chamber outlet is closed and the air inlet 15 is opened so that ambient air flows through the turbine thus scavenging the gases and cooling the turbine parts. The rotary valve 16 comprises two valve plates 17, 18 as shown in Fig.4, and is driven from the turbine and compressor shaft 1 by suitable gearing 20, 21. The fuel pump 22 is also driven from the shaft 1. The valve plate 17 is driven directly by the lay shaft 19 but the valve plate 18 is driven from the shaft 19 through a differential gearing such that the angular position of the valve plate 18 may be adjusted with respect to that of the valve plate 17 thus varying the relative times of the expansion and scavenging phases of the engine cycle. The valve plates 17, 18 each comprise a sector 24 and an arcuate slot 25, the arcuate extents of the sector and the slot of the two plates being different as indicated. In Fig.7 two engines as in Fig.1 are coupled together to drive a common load through suitable gearing, the two engines having a common rotary valve assembly 16<SP>1</SP> which operates so that as combustion gases are discharging on to one turbine, scavenging air is passing to the other turbine.

Abstract: 195,503. Blinded Soldiers' & Sailors' After-Care Organisation, and Fraser, I. Feb. 28, 1922. Delivery of gas; lighters, pipe, cigar, and like; coin action, thrust and weight.-An apparatus for delivering illuminating gas to provide a light for smokers &c. comprises a casing 7, Fig. 1, containing an expansible rubber or like bag 9 having a pipe 13 adapted to be connected by a valve 14, Fig. 5, alternately to a supply pipe 15 and to a pipe 17 leading to a burner 16 which is constantly lit by a by-pass 18 at the top of the pipe 15. The name projects into a sentry-box 21 which is normally closed by a shield 20 secured to a spindle 22 having a threaded portion 23 engaging a threaded hole in a bracket 24 carried by the solid top 10 of the bag 9. When a coin is thrust through a slot 29 into a shoot 30 it moves a bell-crank lever 33, 32, Fig. 6, the arm 32 of which moves a spring-controlled arm 31 of the valve to connect the pipes 13, 15, the arm 31 being held in this position by a pivoted rack 34 controlled by a spring 37. The coin is held in the shoot 30 by the arm 39 of a bell-crank lever 39, 40. The top 10, which is guided by rods 12 and by a rod 25 sliding in a fixed sleeve 27, then rises, rotating the spindle 22 to withdraw the shield 20, and an adjustable stop 41 on the rod 25 moves the arm 40 to release the coin, which drops down the shoot and moves a trip arm 36 depending from the rack 34. This releases the valve arm 31 which is returned by its spring to connect the pipes 13, 17. As the gas is consumed the shield 20 returns to normal position. The bag 9 may be visible and be in the form of a rubber glove.
