Abstract: 1,151,170. Chucks for milling, drilling tools. S. MIZOGUCHI. 24 Nov., 1967 [3 Dec., 1966 (2); 24 Jan., 1967; 13 March, 1967; 1 June, 1967], No. 53677/67. Headings B3B, B3C and B3K. A chuck for a tool 6 such as a drill or end mill, comprises an axially adjustable bevel-closing collet 9 provided with slits 23, 24, those slits which extend from the forward end of the collet terminating in short transversely extending slots 25. The collet is moved axially by means of a screwed nut member 12 and retaining ring 10 mounted thereon by means of balls 11. The chuck includes an adjustable end stop 4 for the tool the shank of which carries a tang engageable with a slot in the stop member. Alternatively, the stop means may carry the tang and the tool shank be slotted. In one embodiment (Figs. 2, 3, not shown), the tool shank is splined and engages corresponding splines in the bore of the chuck. The adjustable stop member is screw-threaded into the bore of the chuck and may be locked in adjusted position, e.g. as shown, by tightening down a frusto-conical member 18.

Title: Anti-hijack system for vehicles
IPC: B60R25/10
Filed: 1971-12-02
Abstract: 1339820 Anti theft devices DYNAMICS CORP OF AMERICA 2 Dec 1971 [18 Dec 1970] 56059/71 Heading B7J [Also in Divisions F1 G1 and G4] Apparatus for preventing hi-jacking of a vehicle comprises means in the vehicle for comparing the route taken by the vehicle with that on a tape and disabling the vehicle if a discrepancy occurs, with overriding means to cope with permissible variations. As shown (Figs. 2a, 2b) the tape 20 is perforated in accordance with the turning points on the route and the distances between them. The actual turning points are determined by a mechanical coupling between the steering wheel and a digital encoder 30 sensing each 90 degree turn. The steering wheel is also associated with an angle transducer producing an angle signal which is integrated at 25 with respect to distance travelled, measured by the rotations of the vehicle drive mechanism, which also drives the tape 20. Thus if the actual distance and direction of travel do not agree with that recorded on the tape 20 an alarm relay 36 is energized, and after a preset delay, clutch 36<SP>1</SP> closes switch 37 to energize an alarm lamp 44 and a disabling relay coil 60. The vehicle may now be driven at a low speed, sensed by tachogenerator 48, for a predetermined distance, until relay coil 56 is energized, those contacts 56<SP>11</SP> energize lamp 67, alarm 66 and disabling apparatus 68. The latter may be by-passed by a coded switch keying apparatus 82, 84, but only after a one hour delay. The vehicle heading signal may alternatively be obtained from a magnetic compass or a heading gyroscope.
Patent GB-1497671-A (GB)
Title: Information processing system
IPC: G06F9/22
Filed: 1974-12-31
Abstract: 1497671 Data processing system NIPPON ELECTRIC CO Ltd 31 Dec 1974 56168/74 Heading G4A A synchronous data processing system includes arithmetic and control units each including data registers operative to receive and store data in response to one cycle of a single-phase clock signal. The arrangement is based on the use of master-slave flip-flop registers, each stage of which includes, in series, an input gate, a master flip-flop, a transfer gate, and a slave flip-flop, the gates being opened and closed at different times within a clock cycle in response to the flanks of a single-phase clock pulse rather than respective phases of a multi-phase clock. The arithmetic unit. Fig. 3, includes registers REG addressed and controlled by signals i and a single phase clock CK<SP>1</SP>, an arithmetic and logic unit ALUFG, and a shift network SHF connected in a closed loop with external connections. To read data from an external memory signals i 7-9  address a register in REG to produce an address which via gate G22 addresses the memory. The resulting data passes via bus M and gate G21 onto bus D and is loaded in a register in REG addressed by signals i 1-3  all in a single clock cycle. The control unit, Fig. 4, includes a read only memory ROM addressed by signals from output B of an eight register set RAREG to generate successive control words i1-i60 to control the system. The registers RAREG are addressed for input and output by addresses a1-a3, and b1-b3 derived from a reversible counter and incrementer/decrementer INC-A. Normally a register is addressed by signals a1-a3 and its output addresses the ROM. At each clock pulse CK the address is incremented by INC-B and fed back to the addressed register and stored. For conditional branches, signal FLAG, when 0, causes incrementing as above, and, when 1, applies data on the bus D to the addressed register to replace the incremented address and cause a branch, again in response to a single clock pulse. For a subroutine call the output a1-a3 of COUNTER is incremented by ING-A to produce b1-b3 and gate G25 is enabled to address RAREG with b1-b3 and apply the data on bus D to the newly addressed register and hence to the ROM to access the subroutine. The normally incromented address is however stored in the previously addressed register by means of a1-a3 to allow a subsequent return. The ROM address is incremented in the usual way through the subroutine until that routine is complete whereupon COUNTER is decremented by INC-A so that a1-a3 = b1-b3 and the return address is accessed and supplied to the ROM. Interrupt operations are similar except that the address in the ROM of the last instruction before the interrupt is not incremented and is accessed again when the interrupt terminates. The Specification includes a brief description Fig. 6(i) not shown, of a system with three processors each with an arithmetic unit as in Fig. 3 time sharing a common memory.

Title: Modular signal processor
IPC: G06F1/03
Filed: 1972-12-08
Abstract: 1404859 Circuit module; waveform generator SANDERS ASSOCIATES Inc 8 Dec 1972 [8 Dec 1971] 56907/72 Heading H3H A module from which signal processing circuits can be built up comprises an input register 16, an output register 18, a functional circuit 17 which performs an operation on the input data and a timing circuit 19 which directs external high frequency clock pulses and lower frequency timing pulses to the correct section of the module. Several modules, each with a different functional circuit, may be connected together with the input of one stage responding to the binary signal operating the output from the previous stage. The timing circuits respond to a first timing signal to enter data into the input register and then to process the data under the control of clock pulses and respond to a second timing signal to output the processed data. In the system described (Fig. 5) four modules are used to form a frequency generator. The modules are a BCD to binary converter, 30 a phase accumulator 50 a "look up table" 70 and a digital to analogue converter 90. The data is in 16-bit serial binary form, but is passed between 30 and 50 and between 50 and 70 in two parallel 8-bit bytes. The desired frequency is set up on selector switches 10-1 which supply a BCD signal to the converter 30. This data is read in by timing signal To and clock pulses #, processed and passed to phase accumulator 50 at timing signal T 4 . The phase accumulator adds the data to either zero or the total already present on a modulo 2 n  basis and at timing signal T<SP>6</SP> passes the new total to "look up table" 70 which comprises a 2 n  number read only memory. The input phase signal (the 2 n  signals cover 360 degrees) acts as an address to select the corresponding sine wave amplitude from the read only memory and at timing signal T 7  this is fed to digital to analogue converter, the output of which is a sine wave of the desired frequencies the system cycles. Preferably each timing signal has a duration of n clock pulses where n is the number of bits in a byte.

The dyes may be obtained by diazotizing an aromatic amine of formula where N is -CH 2 -CH 2 -S-SO 3 X, -CH=CH 2 , or -CH 2 -CH 2 -T (where T is an organic or inorganic radical which can be split off by an alkali) and coupling it with a pyrazole of formula W is -CH=CH 2 , the obtained dye is reacted with a salt of thiosulphuric acid at 15-120‹ C. at a pH of 3-8. If W is CH 2 -CH 2 -T, the dye is reacted with an alkali to give a dye containing a vinyl radical which is then converted to a radical -CH 2 -CH 2 SSO 3 X by the above procedure. The dyes give yellow and orange shades on leather, natural and regenerated cellulose fibres and on nitrogen-containing fibres of animal or synthetic origin e.g. wool, silk, synthetic polyamides and polyurethanes.
