Title: Vehicle detector
IPC: G08G1/042
Filed: 1950-05-23
Abstract: 673,505. Traffic indicating apparatus; bridge circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. May 23, 1950 [May 23, 1949], No. 12924/50. Class 37. [Also in Group XXXVIII] In highway traffic indicating and control apparatus of the kind comprising A.C. fed detectors which co-operate to produce a differential voltage in the presence of a vehicle to actuate an indicator a compensating bridge circuit is included which functions to produce a delayed counter voltage nullifying the differential voltage produced by a stationary vehicle, e.g. a vehicle that cannot proceed due to breakdown. In Fig. 2 a detector D1 comprising a pair of inductively coupled coils D11, D12 is spaced from a detector D2 comprising similarly a pair of inductively coupled coils D21, D22 and both are laid in the highway so that vehicles in a line pass across them. The primary coils D11, D21 are in series and energized from a supply transformer T1. The secondary coils D12, D22 are in series opposing so that with no traffic there is zero voltage across output lines a1, b. If for example a vehicle encounters firstly D1 and secondly D2 voltages opposite in phase appear successively across a1 b and operate a polarized triple-throw relay R1 via a transformer T3 and phase-sensitive amplifier F1 to close firstly for a short interval relay contacts 11/12 and secondly for a short interval relay contacts 11/13 and actuate an indicator via suitable relay arrangements to show both the passing and the direction of passing of the vehicle. A normally balanced bridge comprising equal transformer secondaries S1, S2 within a transformer T2 and equal temperature variable resistors N11, N21 is interposed in series between output line al and transformer T3. A transformer T4 has as its load two heating resistances arranged so that N12 heats N11 and N22 heats N21. In parallel with F1 there is a further amplifier F2 controlling a double-throw relay R2 whose contacts 21/23 when closed short out heating resistor N22 and whose contacts 21/22 when closed short out heating resistor N12. If, for example, a vehicle breaks down over detector D1 there will be applied to T3 a voltage which operates R1 to close its contacts 11/12 and operates R2 to close its contacts 21/23 so that N11 is heated and N22 cools. After a short duration of the latter the opposing voltage thereby produced across T3 will effect release of R1. After a further short interval the opposing voltage effects release of R2 so that N22 is then heated and N11 cools with closure of R2 contacts 21/22. In the operation of the equipment R2 will reverse regularly to maintain as far as possible N11 and N21 at equal temperatures and prevent any prolonged operation of R1 other than for passing vehicles. A resistor M in series with the primary of the bridge transformer T2 produces the phase opposition character of the compensating voltage.

[Class 80 (ii)] [See also Group XVIII] Change-speed gearing for price-changing purposes in prepayment meters comprises driving and driven shafts 3 and 8 carrying paired gears 5 and 9, 6 and 10, and 7 and 11, a series of idler pinions 20, 21 and 22 being adapted to be alternatively brought into mesh with a respective pair of gears on the shafts 3 and 8 by rotation of a carrier 13, in which the idlers are journalled, about an axis 23 which lies in the continuation of the plane of the shafts 3 and 8. Each pair of gears with its respective idler pinion provides a gear train having a different transmission ratio between the shafts 3 and 8. The carrier 13 is held in its alternative positions by engagement of a spring-pressed bush 24, carried by a screw 26 on a main frame plate 2, with one of a series of apertures 30 in an arcuate slot in the carrier 13. A pointer 27 working over a scale on a second main frame plate 1 indicates the price per unit corresponding to the setting of the carrier 13. In a modified construction of Figs. 3 and 4 (not shown), the shafts 3 and 4 each carry a single gear lying in different planes, the carrier 13 carrying a number of idler shafts each with a pair of idler wheels so that any one pair of idler wheels can be brought into mesh each with the gear on one of the shafts 3 and 8. In a modified construction of Fig. 6, a gear 73 on the shaft 3 meshes with three gears 61, 63 and 65 journalled in the fixed frame plates, and a gear 74 on the shaft 8 meshes with toothed wheels secured to three shafts 70, 71 72 each carrying a further gear 62, 64 and 66. Journalled in the carrier 13 is a single broad idler pinion 60, which, by adjustment of the carrier, can connect either the gears 61 and 62, 63 and 64, or 65 and 66, thus providing three different transmission ratios between the shafts 3 and 8.

Abstract: 109,837. British United Shoe Machinery Co., (United Shoe Machinery Co.). Sept. 25, 1916. Bevelling; grooving.-In a machine for bevelling leather strips to form welting for shoes in which the strip is fed between rollers 5, 6, over the end of one of which it overhangs, to permit the bevelling-tool to act upon it close to the bite of the rollers, the overhang part of the strip is supported by a sector 21, the surface of which is concentric with that of the rollers 6 and extends to the bevelling-knife 24. The roller 5 is mounted in fixed bearings, and the roller 6 in a slide 15. The slide is under the pressure of a spring tending to move the rollers together; it may be pushed back to separate them by a cam on the spindle of the hand lever 20. The support 21 is mounted on the slide and carries, adjustably, the bevelling-knife 24. It may be swung back on its clamping-screw 23 as a pivot to bring the knife into an accessible position, and is provided with a rib 31 to form a guide for the front edge of the strip. The rear edge of the strip is in contact with a spring-pressed guide 32 which is connected to the carrier in such a manner that it is moved back when the carrier is moved back to separate the rollers. A grooving-knife 37 may ba mounted on the machine to operate substantially at the bite of the rollers, this, together with a presser-foot 22, is mounted in a carrier 44, pivoted at 8, and pressed up to the work by a spring 49 bearing on a pin 50; the shape of the spring is such that when the carrier is turned back it ceases to press upon the pin. The finished welt passes down a tube 52 mounted to rotate in the head of the machine and driven by bevel-gearing; the tube is curved outwards at its lower end and delivers the welt in the form of a loose coil round a conical projection in a tray mounted in the lower part of the machine standard..

Abstract: 257,327. Parry, P., and Brayne, D. H. May 25, 1925. Electric appliances.-In an electortherapeutic apparatus of the type in which the patient is electrically insulated from the earth and is periodically connected therewith, the make and break device comprises an electromagnet or solenoid, the armature of which makes and breaks the supply circuit of the magnet as well as the patient's earth circuit. Fig. 2 shows the underside of a panel carrying the circuit-breaking apparatus. The swinging pivoted armature c of the electromagnet a has a contact spring k in the magnet circuit and a contact arm p in the patient's circuit. A stud h has insulated and conducting sides, and in one direction of movement of the armature the spring k makes connection with the conducting side to energize the magnet, but when the armature moves in the opposite direction, the spring rubs against the insulated side. The circuit of the magnet is completed by means of switch which connects together the terminals l, n, but to ensure starting when the contact spring is not on the conducting side of the stud h, an auxiliary contact l<1> is provided, whereby the contact-breaker can be shortcircuited. A resistance r, s is included in the patient's circuit. In a modification of the make and break device, Fig. 9, a point h<1> bears against a conducting disc coaxial with the armature pivots. The disc is free to turn relatively to the armature to an extent determined by a driving pin y which engages with opposite sides of a recess z cut in the disc. To break the magnet circuit at the end of the armature swing, a piece of insulating material x<1> is let into the disc flush with the surface.
