Filed: 1958-11-20
Abstract: 869,207. Dampers. BAYERISCHE MOTOREN WERKE A.G. Nov. 20,1958 [Nov. 21, 1957], No. 37427/58. Class 137 A damper assembly comprises a housing with two faces meeting in a corner 61 and 611 to form an angle of less than 180 degrees, an orifice 3 and 4 in each face and a damper 5 pivotally mounted about an edge disposed in the corner and movable to close either of said orifices alternatively. The support 61, 611 may be formed by two separate members or by a forked metal piece 6, the angle formed by 61 and 611 corresponding to the total angular movement of the damper 5. A tension spring 7 connects the damper to a branch duct 4 and retains the rim of the damper in the angle 61, 611 thus closing duct 4 and a control cable 91 attached to the damper via metal strip 8 actuates the damper movement to close duct 3 and thus open duct 4. In the example the damper is used in the hot air duct of the heating system of a motor vehicle, preheated air L entering duct 1 and being distributed via duct 3 or 4 according to the position of damper 5.

Title: System for making Holograms
IPC: G03H1/00
Filed: 1967-08-16
Abstract: 1,157,735. Holography. RADIO CORPORATION OF AMERICA. Aug. 16, 1967 [Sept. 15, 1966], No.37629/67. Heading G2C. In an arrangement for making a hologram on a medium 22, a source of coherent light is positioned in front of an expander to provide a parallel-ray single beam, one portion 18 of which is used as the reference beam and the other portion 24 of which impinges on a light diffuser 26 and the object 28 to be hologrammed. The source may be a laser 10 whose output is focused by lens 12 at a pinhole in element 14 which is at the focus of a lens 16, the light being polarized in a plane parallel to surface 37 of diffuser 26 to minimize reflection losses. The diffuser 26 is at an angle α to the incident beam and consequently the principal component of the emitted light is not in the direction towards the medium 22. To obviate this, the diffuser may be in the form of a deflecting prism (32, Fig. 2, not shown) which deviates a parallel ray of the beam towards the medium (22) the rear surface (34) of the prism being roughened to form a diffuser. All the apparatus may be mounted on an aluminium slab supported on a bed of sand which is itself supported on two further beds of sand to avoid vibrations being communicated to the apparatus. It is shown in the Specification that since the maximum difference in length between the path taken by the reference and information beams d - b is quite small, e.g. 13 mm., it is possible to use cadmium or mercury light sources instead of lasers if the pinhole diameter is about 2 microns.

IPC: G05D3/16
Filed: 1957-12-12
Abstract: 846,410. Electric control systems. BRITISH THOMSON-HOUSTON CO. Ltd. Dec. 9, 1958 [Dec. 12, 1957], No. 38681/57. Class 40 (1). In a machine tool control system of the type comprising control and follower potentiometers forming a bridge circuit, a polarized relay responsive to the out-of-balance current in the bridge diagonal causes the feed to cease and the slider of the follower potentiometer to be reset to its initial position when the bridge is balanced. As shown, the desired movement is set by wiper S 2  of reference potentiometer Rh 2  with wiper S 1  at end of follower potentiometer Rh 1 . When motor switch MS is closed, relay F energizes, preparing a circuit for polarized relay C which energizes energizing clutchoperating relay H. Relay C operates relay IF which locks F and completes the circuit of motor M which effects the necessary drive through clutch H and positions wiper S 1  until S 1  and S 2  are in correspondence when it de-energizes. IF and F de-energize in turn, de-clutching motor M from the work and connecting polarized relay C between the end and wiper of Rh 1 . C energizes energizing IB which again completes the motor circuit to drive wiper S 1  back to near the " x " end of the rheostat. Brakes B1 and B2 lock the motor and driven shafts when appropriate and lamp L indicates when wiper S 1  has been restored and a further movement may be set on wiper S 2 .

Title: Improvements in or relating to communication systems
IPC: H04L1/18
Filed: 1960-11-14
Abstract: 902,206. Telegraphy. SIEMENS & HALSKE A.G. Nov. 14, 1960 [Nov. 13, 1959], No. 39086/60. Class 40 (3). In a telegraph system in which the transmitted and received characters are arranged in groups, there is added to each group a control signal indicative of a characteristic of that group. At the receiver this control signal is compared with a second control signal derived by the receiver from the received character group. If the two signals are not similar, or do not bear a predetermined relation to each other, the receiver transmits a callback signal to the transmitter, which retransmits the incorrectly received group. Stores are provided at the receiver and transmitter for recording the character signals; preferably at least two groups are stored. It is arranged that interference which simulates the reception at the transmitter of a call-back signal, and therefore produces repetition of at least one group, does not cause the receiver printer to print the group characters twice. Faulty reception of a group, Fig. 1.-The transmitter station A transmits the characters a, b, c, &c., and after each seven characters transmits a control signal γ. If the derived, or second, control signal at the receiver B is not γ but, say, #, group II, the receiver transmitter sends a call-back signal # to the transmitter A. The group being transmitted upon reception of the signal #, group III, is terminated by a repetition characteristic #instead of the control signal γ, and the two groups, II and III, transmitted previously, are repeated. On reception of the signal # at B, the two groups II and III previously received and stored are not passed to the teleprinter. The retransmitted groups II and III, if now received correctly, as in Fig. 1, are passed via the store to the teleprinter. Reception of a spurious signal, Fig. 2.-As in Fig. 1, the letters of the alphabet are transmitted sequentially in groups. Group II is received correctly at B, but during transmission of group III the transmitter A receives an interference signal S which simulates a callback signal #. Group III is therefore terminated by a repetition characteristic e, and the groups II and III are retransmitted. At the receiver B the signal # is recognised, but since the previously received control signal and the derived signal agreed, γ group II, the stored signals now blocked to the teleprinter are group III and the retransmitted group II. The retransmitted group III is passed to the teleprinter. An embodiment of the invention is described with reference to Fig. 3 (not shown). With twowire transmission the repetition signal e is not necessary, the transmitter and receiver being connected serially.

Title: A method of and apparatus for transferring formed articles between presses
IPC: B21D43/05
Filed: 1969-08-05
Abstract: 1284607 Transferring articles between presses KOMATSU SEISAKUSHO KK 5 Aug 1969 [21 Sept 1968] 39130/69 Heading B3Q Formed articles 102 are transferred between presses by apparatus comprising rails 101 for supporting both sides of the articles, and loading and unloading carriers 105, 104, each operable cyclically for performing lifting, advancing, lowering and retracting operations and each having a fork for taking an article from, or depositing in, a press. The carrier 105, by means of its fork 110, lifts an article from a press, withdraws it and deposits it on the rails 101. From this point, the article is pushed along the rails in steps by projections 111 on the other carrier 104 until it is lifted above the rails by the fork 109 on carrier 104 and deposited in the next press. The carriers 104, 105 are slidablymounted in a lifting frame 117, the length of the carrier 104 being equal to the distance between presses. The apparatus is driven, through a cam-shaft and gear-box, by a variable-speed motor synchronized with the presses. A cam 119 operates the lifting frame 117 through a lever 118 and a rod 134 which is coupled to four sector gears 123, 141 in mesh with racks 122 on legs 120 of the lifting frame, the legs 120 being supported by pneumatic cylinders 121. Further cams 107, 108, through levers 115, 116 and links 131, 143, effect feed movements of the carriers 104, 105, followers on the levers 115, 116 being kept against the cams by air cylinders (126, 127), Fig. 3 (not shown). A sequence of operations starts with the carriers lowered and retracted, Fig. 2. The unloading carrier 105 is then advanced, followed by a raising movement of both carriers, after which carrier 105 is withdrawn and, at the same time, carrier 104 is advanced to the upstream press. Both carriers are then lowered and carrier 104 is withdrawn. The transition points of the rectangular movement may be made smooth by appropriate design of the cams.

Title: Particle analyzing system
IPC: G01N15/12
Filed: 1972-08-25
Abstract: 1399496 Particle analysis COULTER ELECTRONICS Ltd 25 Aug 1972 [30 Aug 1971]  39709/72 Heading G1N [Also in Division G4] Pulses from a particle analysing device are detected, an analogue parameter of each being converted to a digital computer-acceptable code and fed to a digital computer, detection of further pulses being inhibited for a period after each pulse. Pulses (one per particle) from a Coulter particle analyzing device are, in one embodiment, passed via a gate (optionally preceded by noise exclusion circuits) to a sample-and-hold circuit feeding an A/D converter, both being enabled by a peak-detector also converted to the gate output. The converter output causes one of a number of counts stored in the computer to be incremented, the count being selected by the interface according to the size range. A total count can also be kept e.g. in response to a threshold circuit responsive to the output of the particle analyzing device. The computer can control a printer and/ or graph recorder. The gate mentioned is inhibited after each input pulse by an inhibit device controlled by the peak detector, the particle analyzing device and the interface. A second embodiment replaces the sample-and-hold circuit by a linearity improvement circuit, the peak detector being eliminated, the A/D converter replacing the peak detector in its control of the inhibit device and also serving to reset the linearity improvement circuit. This latter circuit integrates each pulse and compares the integral with the instantaneous value, equality stopping the integration, the resulting value representing the volume of the particle and being supplied to the A/D converter.
