Title: Hydropneumatic impact absorptive device
IPC: F16F9/06
Filed: 1971-11-23
Abstract: 1374587 Hydropneumatic shock-absorbers NISSAN MOTOR CO Ltd and ATSUGI MOTOR PARTS CO Ltd 23 Nov 1971 [26 Dec 1970] 54330/71 Heading F2S A shock absorber, e.g. for use with a fender 50 such as a motor vehicle bumper has a piston 36 slidable in a cylinder 16 (the "cylinders" herein need not be of circular section) with a one-way valve 42 in an end wall and a row of apertures 38 extending its whole length and immersed in liquid such as oil in the cylinder 16 and in an outer cylinder 10, there also being gas 26, such as nitrogen, under superatmospheric pressure, either in a compartment divided from the liquid compartment 24 by a movable partition such as a bellows, diaphragm or floating piston 30, or in intercommunicating upper portions of the cylinders 10 and 16, Fig. 2 (not shown), unseparated from the liquid which immerses the apertures 38 (which in such embodiment are in the lower portion of the inner cylinder wall). In these embodiments, the piston-rod 46 carries the fender 50 and the cylinder 10 is secured to a main structure such as a motor vehicle body. In a third embodiment, Fig. 3 (not shown), the outer cylinder (10) carries the fender and the piston-rod (46) is secured to a main structure together with a sleeve (54) in which the outer cylinder (10) telescopes so that the device is stiffened against bending. A resilient sleeve (56) covers some of the apertures (38) which are thus open only at high liquid pressure. The shock absorber may have a floating piston (30) as in Fig. 1, or the liquid and gas may be unseparated as in Fig. 2.  In all the embodiments, impact on the fender 50 causes liquid to pass out of the inner cylinder chamber 22 to find its way back in behind the piston 36 through an aperture 38<SP>1</SP>. Build up of pressure in the compartment 24 acts, e.g. on the movable partition 30, to compress the gas 26 which thus causes the return of the piston 36 after the impact. When the pressure in the inner chamber 22 reaches a certain level, e.g. as a result of abnormal impact, the check valve 42 is opened to release liquid into the compartment 24. In Figs. 1 and 2, the valve 42 is a pliable plate. In Fig. 3, the valve (42<SP>1</SP>) is a plate loaded by Belleville washers.

Abstract: 1330555 Molybdenum-base alloys METALLWERK PLANSEE A G & CO K G 24 Nov 1971 [24 Nov 1970] 54650/71 Headings C7A and C7D [Also in Division F1] A turbine blade consists essentially of alloys of molybdenum, hafnium and boron and may additionally contain zirconium, tungsten and carbon. The percentage proportions by weight may be, in addition to molybdenum:- 0À05-2À0 Hf, 0À002-0À02 B, 0À05-2À0 Zr, 0À03-0À07 W, up to 0À05 C and less than 0À0035 O. The blade may be made by producing the compound Hf 9  Mo 3 B 2  by pressing mixtures of hafnium hydride, molybdenum and boron at 1400‹ C for 8 hours in a vacuum. The reaction product is milled into grains and then mixed with molybdenum powder and molybdenum boride before being pressed in a mould to the blade shape. The part is sintered in hydrogen for 4 hours at 2000‹C, cooled, reheated in hydrogen to 1300‹ C and, whilst reducing the temperature in stages, is drop forged to final shape before annealing at 1000‹ C. Additional refinement may be carried out by annealing at a temperature above 1500‹ C in nitrogen. Alternatively the blade may be produced by compressing a powder mixture of molybdenum, boron and hafnium with or without zirconium into a bar which is then fused into an ingot in a vacuum arc smelting plant. The ingot is extruded and shaped by drop forging.

Title: Signal Converting Storage Tube
IPC: H01J31/60
Filed: 1968-11-18
Abstract: 1,183,029. Cathode-ray storage tubes. HUGHES AIRCRAFT CO. 18 Nov., 1968 [6 Dec., 1967], No. 54651/68. Heading H1D. A storage target for a cathode ray tube using the same beam for reading and writing, comprises a dielectric substrate of quartz, mica or glass on which is deposited a grid of gold, molybdenum or nickel. The substrate may be # inch thick and the grid may be 10<SP>4</SP> Š.U. thick and may be deposited by a photo-resist method or by nucleation image formation. The grid may comprise parallel lines or a mesh of intersecting lines, and is disposed on the beam side of the target. A decelerator mesh electrode is disposed about 1/10 inch from the target and may be at a potential of 750 volts. Erasure is accomplished by raising the potential of the storage grid above the secondary emission cross-over point so that the target is raised to collector potential when scanned. The grid potential is then lowered to 15 volts so that the target is reduced to cathode potential when scanned. In writing, the grid potential is raised above the cross-over point, e.g. to 350 volts, and the electron beam is modulated in intensity, width, or deflection speed so that the exposed areas of the target are changed positively in accordance with the input signals. The grid potential is then reduced to 4 volts, thereby reducing the potential of the storage elements by a like amount by capacity coupling so that they are all below cathode potential, and the stored charges control by mirror action the ratio in which incident electrons divide between the grid and the decelerator mesh electrode, either of which may provide the output signal.

Title: Apparatus for decoding digital information
IPC: G11B20/14
Filed: 1971-11-25
Abstract: 1339840 Data code converters GENERAL MOTORS CORP 25 Nov 1971 [1 Dec 1970] 54732/71 Heading G4C Serial non-return-to-zero binary data is derived from a signal, e.g. C.D. Fig. 2, in which a pair of 1-bits is represented by a transition occurring at the beginning of a bit cell and a part of 0-bits by a transition occurring at the centre of a bit cell. In the circuit disclosed, Fig. 1 (not shown), the input signal CD, e.g. read from a magnetic record medium is fed to an assembly (30) of NOR gates acting as a monostable unit to provide a signal TRANS in which a pulse occurs at each transition in CD. Signal TRANS is gated with bit rate anti-phase clock signals A#, B# to generate a signal 1-TRANS representing the 1- bit-pair transitions and a signal 0-TRANS representing the 0-bit-pair transitions. Signal 1-TRANS is fed via gates to the first and the even-numbered stages of an n-bit shift register (R2). The remaining stages are fed, also via gates, with signal 0-TRANS. A second n-bit shift register (R1) acts as a counter, the number of stages set corresponding to the number of bit periods that have occurred since the counter was last reset. The counter is reset at each transition in the signal CD by a signal CLRCNT generated from TRANS and B#. The registers are stepped at bit rate by B#. The counter (R1) is so arranged that its first two stages are set after each transition. Consequently, when a pulse occurs in 1-TRANS it sets the first two stages of the first register (R2) to 1. If a pulse in 0- TRANS occurs the first two stages remain at 0. When no transition occurs two bit periods after a transition, e.g. as at the end of bit time 8 in Fig. 2, the data in the first register (R2) continues to be stepped through so that at the end of time 12 the bit pair 11 set in stages 1 and 2 at the end of time 6 is in stages 7 and 8, the stages 1-6 all being at 0. If a pulse 1-TRANS occurs at the end of time 13 this pulse passes via the enabled gates to stages 1, 2, 4, and 6 so that the register (R2) contains 10101011 corresponding to the data for times 8-15. Had a pulse 0-TRANS occurred during time 14 the register would have been set to 01010100. The register output is the required NRZ binary data.

Title: A process for the recovery of unsaturated cyclic hydrocarbons
IPC: C10G21/14
Filed: 1965-12-28
Abstract: Unsaturated cyclic hydrocarbons are recovered from mixtures also containing ammonia by extraction with a non-aromatic hydrocarbon having at least 8 carbon atoms and having a density of at least 0.05 gm/ml. greater than that of ammonia, measured at 40 DEG  C., and subsequently extracting the unsaturated cyclic hydrocarbon from the extract.  Suitable non-aromatic hydrocarbons are decane, dodecane, cetane and decalin.  The recovery process is particularly suitable for use in conjunction with a process in which aromatic hydrocarbons, e.g. benzene or toluene, are partially hydrogenated in the presence of an alkali metal and liquid ammonia.  In the case of benzene, the reaction mixture from the hydrogenation process will, after removal of sodium amide, comprise liquid ammonia, benzene, and cyclohexene. From this mixture, benzene and cyclohexene are separated by the solvent, as above, and the extract can be further treated with a countercurrent flow of liquid ammonia which removes te benzene.

Abstract: 1335060 Data recording; transcribing ANSTALT EUROPAISCHE HANDELSGESELLSCHAFT 9 Dec 1970 [11 Dec 1969] 58528/70 Heading G4H An apparatus for selectively writing on to, reading out from, and transcribing between dynamic data recorders includes at least one read/write magnetic storage unit, at least one read and at least one write punched tape device, a serial/parallel converter for signals being passed between the magnetic unit and the punched tape devices, the converter being driven in synchronism with those devices, and a switching means for selectively interconnecting the devices and external input/output devices. As described three bit parallel data is received from, e.g. a typewriter input on lines 11 and transferred via reversing switches 8, 13 and 16 to punched tape by means of the device 32. This tape may be transferred to the punched tape reader 30 and the signals routed (by means not shown) to the device 32 to form a duplicate tape. During this process errors may be corrected by connecting the typewriter via switches 8, 13 and 16 to repunch erroneous passages. The duplicate tape is then placed in the reader 30 and its contents transferred to magnetic tape by means of switches 16 and 13, a rotating wiper 9, acting as a serial/parallel converter, and magnetic tape unit 26. A mechanical Maltese cross indexing arrangement, Fig. 6 (not shown), is described for synchronizing the reader 30 with the tape and serial/parallel converter. The contents of the tape may then be transferred at high speed via lines 11 to an output printer. The punch tape reader may be reversible to allow corrections to be made. In an embodiment two magnetic tape units, two punched tape readers and a tape perforator are provided. A number of output printers may be driven simultaneously and an automatic date device may be provided to cause the date to be printed with the output. The system allows data to be recorded slowly and accurately on punched tape, transferred to magnetic tape and read out at high speed. Other paths through the switching system may be used, e.g. the tape unit 26 may function as a data store when it is directly coupled to the input/output lines 11. The tape may be mounted in a cartridge. The tape unit 26 may be multitrack with a separate channel, each including a serial/parallel converter, provided for each track. The punched tape units in this latter case handle 3n bits in parallel where n is the number of tracks on the magnetic tape. Magnetic discs &c. may also be used.

Filed: 1972-12-22
Abstract: 1377860 Data processing HITACHI Ltd 22 Dec 1972 [24 Dec 1971] 59464/72 Heading G4A The output of a binary coded decimal full adder AD (Fig. 1) including a correction circuit is connected, via cascade connected shift registers Rxa, Rxb, to a further shift register Ry, the output of which is connected to the full adder. As described an indicator IN receives an input from the least significant digit position of the registers Rxa, Rxb. Addition.-The outputs of shift registers Rxa, Ry are connected to a first binary full adder FA 1  (Fig. 3), binary carry being effected by a one bit delay circuit DL 2 . The output of the adder FA 1  is fed via a four bit delay circuit DL 1  controlling the correction circuit CC to a second full adder FA 2  receiving its second input from a correction generator CG, supplying a digit 6 when enabled by the correction circuit CC. Carry in the second adder is effected via a one bit delay DL 3  disabled when the most significant bit of a digit is being processed. The output of adder FA 2  is connected to the shift register Rxb. A sum from adder FA 1  of between 0 and 9 results in no decimal carry to the next digit from delay circuit DL 2  and no operation of the correction circuit CC. A sum of between 10 and 15 results in operation of the correction circuit CC to provide both a decimal carry to adder FA 1  and generation of the digit 6 to be added to the sum from adder FA 1  in adder FA 2 . A sum of between 16 and 19 results in a decimal carry being generated by adder FA 1  which operates correction circuit CC to generate the digit 6. In a modification (Fig. 4) for sums between 10 and 15 the decimal carry is derived from the delay circuit of the second full adder. Multiplication.-This is effected by repeated addition. The multiplicand, stored in register Ry, is added a number of times determined by the multiplier, stored in register Rxa, the result being stored in register Rxb and the multiplier decremented each time. The number in register Rxb is shifted one step right as each digit of the multiplier is processed. When the multiplier becomes zero the resulting product is shifted into register Rxa. Division.-This is effected by repeated subtraction. The dividend is stored after depression of the equals key in register Rxb and the divisor in register Ry. The contents of register Ry are then subtracted from the contents of register Rxb until the contents of the latter becomes zero, the number of times this is effected being stored in register Rxa.

Abstract: 1368620 Selective signalling NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP and FUJITSU Ltd 23 Dec 1971 [26 Dec 1970] 60093/71 Heading G4H A control unit, for controlling, e.g. a typewriter in response to codes from a computer, stores each code and detects if it requires longer than the standard time interval for execution, and if so, inserts an idle signal, having no control effect, after it to fill the longer time interval. The input code is passed to an assembly buffer and also decoded to address a permanent memory and if it represents a typewiter control function, as distinct from a character to be printed, the addressed memory location is non-empty, containing an indication of the interval required. This is passed via a register and decoder to produce a pulse of appropriate duration from a timer. This pulse, during its duration, inhibits the path from the firstmentioned store to the assembly buffer, inhibits transmission to the computer of a request for the next code, and gates idle codes at regular intervals into the assembly buffer. The assembly buffer controls the typewriter via a serial-toparallel converter and line unit. As a modification the time interval may be controlled by counting the idle codes, or a duration-significant signal may be used in place of the idle codes.
