Title: Road traffic detection and control system
IPC: G01S13/92
Filed: 1956-05-18
Abstract: 816,834. Radar. EASTERN INDUSTRIES Inc. May 18, 1956 [May 31,1955], No. 15658/56. Class 40 (7). [Also in Group XXXVIII] A road-traffic detector system for controlling traffic signals comprises an ultra-high frequency directional antenna 15 disposed above the road and directed at a small angle to the vertical in the direction of approaching traffic 10, the antenna being associated with a Doppler radar system 30-37, the pass band of which for the detected beat frequency due to the Doppler shift is restricted to a low-frequency range and such that an output is obtained only in response to a vehicle passing through a zone substantially under the antenna where its velocity relative the antenna, and with it the Doppler shift, falls momentarily to zero. The particular embodiment described utilizes an antenna beam width of 30 degrees, the beam being directed at 15 degrees to the vertical. The frequency of operation is 2455 Mc/sec., and the pass band, which is determined by the combination of filters 31 and 33, is approximately 20 c/s wide centred on 30 c/s. The output signal, comprising a pulse for each vehicle, is detected at 35 and applied to actuate a relay 37 via an amplifier 36. The duration of each pulse is inversely proportional to the speed of the vehicle producing it and may provide information of speed to a suitable utilization circuit. A gain control following filter 33 controls the sensitivity of the system and hence the effective lateral coverage of the detector. By inclining the antenna so that one edge of the beam is substantially vertical, no pulse is produced in response to a detector leaving the detection zone. Reference is made to the use of a beam inclined away from the approaching traffic. Fig. 4 (not shown) illus. trates a detailed circuit for the system; the antenna comprises an in-phase array of eight dipoles arranged in two columns side-by-side and backed by a reflector plate, and the oscillator-detector 30 comprises a lighthouse-type triode. The remainder of the circuits of the system are conventional. Fig. 5 (not shown) illustrates a housing arranged for attachment to a support arm and having a lower part in the form of a radome to accommodate the antenna and an upper part to accommodate the associated circuits. The antenna and circuits, which are arranged to be removable from the housing as a unit, may be placed therein in either of two positions 180 degrees apart to allow for use with either left- or right-hand mountings. Locating means are provided to ensure correct positioning.

Abstract: 1,002,114. Consecutive-access gramophone record changers. WARWICK ELECTRONICS Inc. April 15, 1964 [April 29, 1963], No. 15688/64. Heading G5R. To prevent clattering and/or damage to records descending a centre-post 14, retractable supports 43, Fig. 4, positively lower the record on to the upper of two concentric turntables 15, 10, Fig. 1, which upper turntable is frictionally driven by the lower and prevented from rotation by brake means, Fig. 6, when the record is being placed on it. An actuating spindle 22, besides operating known stepped-post means 19, 20, Fig. 2, raises and lowers the supports 43, arranged to interleave the changer members, Fig. 3, the largerthan-normal stroke being achieved by rack-andpinion means 44, 46 actuated by a horizontally sliding member 34 operated by conventional cycling means. The upper turntable 15 is arranged to be freely rotatable with a boss 21, resting on the lower turntable boss 23, Fig. 5, both being centred by the spindle 22, drive rollers 17 transmitting a limited drive between the turntables which is overcome, during record-changing by the brake-shoe 57. The supports 43 appear resiliently through spindle grooves 40, unless retracted by the boss 21, Fig. 5, or by the centre-hole of a supernatent record, previously lowered. In a second embodiment Figs. 8-19, not shown, to prevent the next-to-lowered record from adhering to the record stacked next-above it and failing to be lowered when the changer mechanism releases it, additional lifting means are provided for the lowering supports to slightly raise the entire stack by pressing the lowest record upwardly against its neighbour. When this has occurred, it is found that the two lowest records in the stack no longer adhere one to another and the lower is then reliably lowered to the upper turntable.

Title: Improvements in or relating to railway axle counting equipment
Inventor: BROWN ANDREW
IPC: B61L1/16
Filed: 1948-06-11
Abstract: 696,544. Railway axle-counting signalling systems. STANDARD TELEPHONES & CABLES. Ltd. June 11, 1948. No. 15814/48. Class 105. A railway axle counting equipment with the passage of the wheels inductively affecting a circuit by which the passage of each wheel is signalled is provided with two normally operative electrical members (discharge tubes) one responsive to the receipt of a signal and the other (or both) being responsive to any abnormal change in the electrical equipment (breakage of a lead or battery failure) so that any fault causes the apparatus to denote that the track is occupied. In the arrangement shown two discharge tube sections 1a, 1b enclosed in a common envelope 1 respectively include in their anode circuits relays 3, 4 with the grid line 2 to the discharge tube la being so affected by the inductive signal given on the passage of each wheel that the anode current is momentarily zero whereby the relay 3 causes the axle counting mechanism to be operated. The discharge tube section 1b and relay 4 normally remain energized but on breakage of a lead thereto or on battery failure they become currentless and give a warning signal actuating the axle counting mechanism to denote the track is occupied. Absence of voltage on the line 2 to the grid of tube 1a due to a broken lead will simultaneously give a warning signal. The two tubes 1a 1b have a high resistance 5 in their common cathode line ; receipt of an axle-counting signal reduces the voltage on the grid of tube 1a with the result that the total anode current of the tubes 1a, 1b falls and thereby in effect lowers the cathode voltage and so increases the anode current of tube 1b to effect some compensation in the cathode voltage the effect being to ensure that the tube 1a becomes currentless for the requisite percentage change of voltage in its grid circuit. The two discharge tubes may be separate each with their own envelope and the discharge tube 1a may actuate the axle counting mechanism without the intervention of the relay 3. Specifications 683,022, 696,543 and 696,543 are referred to.

Title: Improvements in or relating to power driven typewriters
IPC: B41J3/50
Filed: 1939-05-30
Abstract: 529,983. Typewriters. CREED & CO., Ltd., THOMPSON, A. E., and SALMON, R. D. May 30, 1939, No. 15920. [Class 100 (iv)] Relay type - wheel actions. In a keyboardcontrolled poweroperated typewriter, a type-wheel is stopped in character - selecting position by key-controlled detents which are moved successively into co-operation with rotatable rows of stops to select progressively and directly the character to be printed. The type-drum 17 shown in the Figure is splined on a shaft 20 geared to a sleeve 3 which is frictionally mounted on a driving-shaft 2 and is provided with rows 3a ... 3d of stops for co - operation with pivoted detents 4a ... 4d. The stop 3d has four equi - distant arms arranged at an angle of 45 degrees to a double arm constituting the stop 3c, and to single, opposite arms constituting the stops 3a, 3b. The detents 4b ... 4d have arms for co-operating with interponents 10 pivoted to combination bars 11b ... 11d controlled by the keys. The interponents co-operate with cams on a sleeve 9 which is driven through a one-revolution clutch at half the speed of the shaft 1, the cams being angularly spaced in correspondence with the stops 3a ... 3d. The detents co-operate with a latch 27 which engages a cam-operated lever 26. If the combination bar 11a is fully displaced, the associated camoperated interponent 10 rocks the detent 4b, the latch 27 is depressed by the detent 4b to release the detent 4a, and the sleeve 3, after making a half-revolution, is arrested by co-operation of the stops 3b, and detent 4b. Similarly, if the combination bars 11a, 11b are fully displaced, the sleeve is arrested by the stop 3b and detent 4b, and then by the stop 3c and detent 4c,. the total movement of the sleeve being threequarters of a revolution. If all the combination bars are fully displaced, the stop 3d and detent 4b also become effective, and the sleeve makes a total movement of seven-eighths of a revolution. After operation of a printing hammer by a cam on the sleeve 9, the detent 4a and latch-lever 26 are operated by other cams, and the sleeve and type-wheel are arrested in initial position. The apparatus may be associated with tape-perforating mechanism, the punches being operated individually by the cams that operate the interponents 10. Alternatively, the sleeve 9 may be provided with a cam for operating a punchblock. Signal-transmitting mechanism under control of the perforated tape or the combination bars may be driven by the same motor as the above-described apparatus. Case - shift mechanism. A type - drum 17 is shifted axially by means of a slide 16 provided with a roller 15 co-operating with a helical cam 14 or a snail cam which is rotated through a variable angle under control of stops 2a ... 2d and detents 5a ... 5d operating in the same manner as the stops 3a ... 3d and detents 4a ... 4d. Alternatively, shift keys may be arranged to operate the type-drum directly.
