Title: Method of ciphering messages
IPC: H04L9/18
Filed: 1962-08-07
Abstract: 951,174. Ciphering messages. GRETAG A.G. Aug. 7, 1962 [Aug. 18, 1961], No. 30248/62. Heading H4P. In a system for transmitting messages in ciphered form of the kind in which the message pulses are mixed with cipher pulses at the transmitting station and are deciphered at the receiving station by the use of an identical set of pulses, the transmitter and receiver both have cipher generators of identical construction for producing identical cipher sequencies determined by the initial state of the generator, wherein the number of possible initial states is very large and the initial state is determined from a first value stored at both stations and a second value determined at random at one of the stations and transmitted to the other. Transmitting and receiving stations 10, 12, Fig. 1, e.g. teleprinter S, are connected to the transmission line 16 via mixers 14 and 18. At each station there is a cipher generator 20, 22. The first value is stored in units 24 and 26, which may be punched tape, or other record readers, and the second value is generated by a random generator 28 at the transmitter and passed to the receiver over lines 30, 32. This value is stored at 34 and 36. The two values stored at each station are combined in a mixing unit 38, 40 to provide an initial state for the generators 20, 22. The mixers may consist of a gating circuit, Fig. 2, consisting of an Or gate 56 and an And gate 58 which pass a combination of a " 0 " and a " 1 " and " 1 " and two " 1's " or two " 0's " as " 0." The random generator 28 may consist of a noise generator which controls the gating of pulses to a punching machine to punch into a tape random punched holes in 5-bit code. The tape is read to derive the random second value. The stores 24, 34 and 26, 36 may be shift registers, corresponding digits being successively passed to the mixers. The resultant value may also be stored in a shift register, the stages of which are connected to set the stages of a counter 120, Fig. 7. The outputs of successive stages of the counter are connected via mixers 134 to storage stages 132 acting as five three-stage shift registers in closed loops in which circulate patterns depending on the value in the counter. Further mixers 146, 148, 150 and 152 in the inputs to some of the mixers 134 receive the outputs of And gates 138, 140, 142, 144 connected to the recirculation loops of some of the shift registers. Between the shift register stages are interchange switches operable by magnets 160, 162, 164 controlled by pulses within the loops. The outputs on five leads 170 are serialized by a distributer 170. The output bears a complex relationship with the state of the counter and is used to cipher the message for transmission.

Title: Holograms
IPC: G03H1/00
Filed: 1971-06-29
Abstract: 1335604 Stroboscopic holograms BROWN BOVERI & Co Ltd 29 June 1971 [1 July 1970] 30349/71 Heading G2J A hologram of a vibrating object 3 is produced by stroboscopically illuminating the object with light which is pulsed synchronously with the vibration of the object, there being a plurality of pulses for each cycle of vibration of the object, whereby the image reconstructed from the hologram will include a plurality of corresponding isoamplitude lines. A sinusoidal generator 7 actuates a sound transmitter for setting the object in standing oscillations. These mechanical vibrations are picked up at 9 and converted to electric oscillations which are fed to a saw-tooth generator 10. This through signal channel discriminator 11 and amplifier 12 produces strobe pulses which actuate a modulator, e.g. a pockets cell 13. This may be in the object beam, the reference beam or as shown in the laser beam before it is split. The pulse spacing is arranged to provide equally spaced iso-amplitude lines or lines of equal brightness. The strobe pulse are produced as a result of the electric signal being chopped into modulus of 2 #. The pulse light is preferably an amplitude-modulation with the junction n #  k=o  Cos (Kz o  sin (#t + #)) where z o  is a selected amplitude, # is the angular frequency of the vibration of the object, # is a phase-constant and n is the ordinal number of the greatest amplitude of vibration of the object to be reproduced.

Title: Improvements relating to the automatic regulation of the speed of vehicles
IPC: H02P23/16
Filed: 1961-08-25
Abstract: 937,629. Automatic speed control. DAIMLER-BENZ A.G. Aug. 25, 1961 [Aug. 26, 1960], No. 30763/61. Class 38 (4). [Also in Group XXXI] A vehicle is started when shaft 11 and lever 12 are turned by pedal 10 to a desired position. Coupling element 19 turns about pivot 22 so that lever 14 and sleeve 13 are actuated by rod 20, throttle 16 being opened by linkage 15 to accelerate the vehicle. When the speed exceeds a value corresponding to the position of the pedal, arm 31 is deflected to close contacts 29, 29<SP>1</SP>, and energize relay 38, whereby servomotor 24 drives element 23 to the right. Link 19 turns about pivot 46, the throttle being moved in the closing direction. If the pedal is further depressed, contacts 28, 28<SP>1</SP> are closed through links 25, 26 and the rod 23 is displaced to open the throttle until a new speed is reached and contacts 28, 28<SP>1</SP> re-open. The motor 24 is associated with limit switches 39, 40. The speed obtainable by movement of the pedal is restricted by resilient stop 47 adjusted by cam 48. To render the speed regulation inoperative, cam 52 is turned by knob 51 to short-circuit contacts. 28, 28<SP>1</SP>. Relay 37 is energized and the motor 24 moves element 23 to the left until limit switch 39 is actuated. Pivot 22 is then situated in the middle of coupling element 19, the throttle 16 being actuable by the pedal in the usual manner. Lever 12 may be held in position by a magnet, allowing foot pressure on the pedal to be relieved. The resilient stop 47 may be replaced by a magnet. In another arrangement a voltage dependent upon the position of the pedal is compared with a speed-responsive voltage. According to the sense of the error voltage, transistors deliver impulses to the relays 37 or 38, Fig. 3 (not shown). In a further embodiment, two groups of contacts are deflected in relation to each other in accordance with the difference between the desired and actual speeds of the vehicle. As the deflection increases, resistors are removed from the circuit of servomotor 24 and the speed of that motor increases, Fig. 4 (not shown). Transistors serving as selector switches may control power transistors in the exciting circuits of the motor 24, Fig. 5 (not shown). A plurality of contacts may be arranged on each side of a speed-responsive contact so that a plurality of gearchanges may be effected until a desired speed is maintained. A gear change occurs only after the normal range of regulation by the throttle has been completed. One of the contacts may be associated with a brake, Fig. 7 (not shown). The servomotor 24 may be replaced by a hydraulic servomotor.

Abstract: 816,688. Counting-apparatus. NEWMAN, HENDER & CO. Ltd. Oct. 31, 1957 [Oct. 9, 1956], No. 30770/56. Class 106 (1). [Also in Group XXXVII] Means for actuating an electric impulse counter comprises a spring-loaded lever arm for engagement at one end with the articles to be counted, which closes a micro-switch fixed thereto at its other end. The arrangement shown is applicable to counting articles of non- uniform size such as eggs, but is described generally. A U-shaped bracket 13 fixed to the housing 8 supports a spindle 14 on which is pivotally mounted a bracket 16 carrying a micro-switch 17 to which is secured a lever 18. Mounted freely on the spindle 14 is a V-shaped support 20 having lugs 21, 22 provided with adjustable screw stops 23, 24 between which an extension 25 of the bracket 16 is positioned. The support 20 is mounted between friction discs 26 to which pressure is applied by a spring 27, the pressure being adjustable by a nut 28, and the arrangement being such that the initial movement of the lever 18 moves the extension 25 across the gap between the stops 23, 24 to operate the micro-switch by bringing the actuator arm 29 into abutment with the lug 22 thereby actuating an electric impulse counter (not shown). Further movement of the lever 18 as it rides over the article to be counted causes the whole assembly of microswitch and support to move. The return movement of the lever 18 under the action of the return spring 19 moves the extension 25 from the stop 24 to the stop 23, whereupon the actuator arm 29 moves away from the lug 22 to open the micro-switch, continued movement causing the whole assembly to rock on the spindle 14. The spindle 14 may be replaced by two portions having conical ends mating with corresponding seatings in the bracket 16.

An auxiliary supporting member 17 also suspended from the bracket 1 is slidably connected, e.g. by an arm 19, to the member 13 and includes means. such as nuts 20, to take the weight of the pipe-line should breakdown of the spring support device occur. The rod 5 may be disposed tangentially to an eccentrically mounted toothed wheel 3 over which the chain 4 passes. The chain may also engage over a jockey wheel 10. The spring 6 may be arranged vertically, as shown, or horizontally. To facilitate compression of the spring 6, a sleeve 5a may be screwed onto the rod 5 and locked in the adjusted position by a nut 8 : a tube 9 may be used to prevent lateral distortion of the coils of the spring. The member 13 may be in two parts connected by a turnbuckle 15 which allows adjustment of the final position of the pipe-line. A removable split tube may be inserted between the stop 19 and the nuts 20 so that the member 17 temporarily supports the pipe-line during erection thereof. Where the device is used to support a pipe-line subject to upward expansion a split sleeve 21 is disposed between the cap 7 pivoted to the bracket 1 and a collar 22 on the rod 5 while adjustment of the spring 6 and turnbuckle 15 is made.
