IPC: G08G1/16

Abstract: 1,234,352. Train control system. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 1 Oct., 1969 [2 Nov., 1968], No. 48174/69. Heading B7N. [Also in Divisions H3-H5] The distance between two vehicles 1, 2, e.g. trains, constrained to move along a predetermined path is determined and used for anti-collision purposes, by the front vehicle I inducing a C.W. signal in an open transmission line 3 laid alongside the path, successively modulating the signal at spaced points 4 along the line, picking off the modulated signal at the following vehicle 2, and determining the distance as proportioned to the depth of modulation on the signal. Each vehicle carries a transmitter 1a, 2a, a receiver 1b 2b and an aerial 1c 2c. Switches 1d and 2d normally couple transmitter 1a to aerial 1c and aerial 2c to receiver 2b, but can reverse the path. The modulation is carried out in discrete steps in transistors 4 using a modulation signal from generator 5. The receiver 2b is connected to demodulator means 8 to give a signal at the input to gate 7 proportional to the modulation and distance. A detector 6 ensures that gate 7 is only enabled when the overall signal strength is above a predetermined threshold. The distance output of gate 7 is caused to activate a brake system 11, via control means 10 when the distance has dropped to collision possibility dimensions. The stopping or slowing down of vehicle 1 is detected by means 12, detecting the rate of change of the degree of modulation, and rapid decrease of the distance causes rapid application of brakes. A vehicle wheel/road adhesion measuring means 14, may control the rate of braking to overcome dangers of skidding.

Abstract: 1,234,621. Testing ampoule charges photoelectrically. EGYESULT IZZOLAMPA ES VILLAMOSSAGI RESZVENYTARSASAG. July 25, 1968 [Aug. 18, 1967], No.19748/67. Heading G1A. Apparatus for detecting solid impurities in liquids contained in ampoules comprises two gratings on opposite sides of the ampoule and an optical system for imaging the lines of one grating on to the spaces of the other whereby refraction of light by the impurities varies the amount of light that can pass both gratings to reach a photo-electric device. Light from a source 1 passes through an adjustable field stop 3 and is collimated by a lens 2 on to a grating 4. Grating 4 is imaged by lens 5 on to grating 6 so that with no ampoule present no light reaches the photo-cell 11. The contents of ampoule 8 are agitated by a magnetostrictive ultrasonic generator 10 and allowed to settle. The output of cell 11 has a D.C. component of magnitude dependent upon strains in the ampoule and an A.C. component if solid impurities are present. An A. C. amplifier 12 responds only to the A. C. component to indicate the presence of impurities.

Abstract: 1,252,706. Moulding plastic substances. HOLLYMATIC CORP. 9 April, 1970 [13 Oct., 1969], No. 16917/70. Addition to 1,152,521. Heading B5A. A hopper and plunger type apparatus for producing articles such as food patties, includes a hopper 38 in which a feeder 54 is reciprocated for forcing material therefrom into a mould cavity 50 in a reciprocatory mould plate 25 which slides between plates 36, 37; and after each moulding stage is moved to an article discharge position. The drive mechanism of the mould plate and feeder includes a lost motion between the plate and feeder, and includes a catch mechanism which retains the feeder in its material feed position until the mould plate has been moved away from its material receiving position. Such drive mechanism includes opposed pairs of racks 23 and 31 interengaged by gear-wheels 33 and driven by a linkage 15, 16, 17, 19 and 21 so that they reciprocate in opposite directions, the lower racks being connected to the mould plate and the upper racks to a cross-bar 53 driving the feeder. The cross-bar is located between the head 58 of a pin 56 connected to the feeder and a collar 63 screwed to a tube 61 through which the pin passes; the collar is urged to the right, Fig. 4, by a spring 56 acting on a nut 60. A catch 65 for holding the feeder in the material feed position is pivoted on a pin 66 and has an arm 70 with a sector shaped catch member 71 rotatable about a pin 72. A spring 76 urges the member 71 to the position shown in Fig. 4 where an abutment on the member engages the upper surface of the arm 70. During the feeding stroke the bar 53 abuts the collar 63 to force the feeder to the left, Fig. 4, and the material to the mould cavity via passages 42, 52. The collar pivots the member 71 about its pin 72 to reach the position shown and is locked in this position by the member and by a stop bar 81 attached to the bar 53 and which overlies a projection on the member 71. After the moulding step the mould plate 25 is moved to the left to an article discharge position and the bar 53 to the right until it engages the head 58, in which position the bar 81 allows disengagement of the catch enabling retraction of the feeder. The drive imparted to the racks via the linkage 15, 16, 17 and 19 has a lost motion provided by a slot in a lower rack engaged by a drive pin 27. The latter also drives a cam plate 22 having a notch 91 which engages a pin 89 in the article ejection position of the mould plate whereby a spring-loaded shaft 86 is lowered to cause a knock-out plate 84 to discharge the article from the mould plate.
