Title: Improvements in and relating to snow ploughs
IPC: E01H5/06
Filed: 1952-06-20
Abstract: 721,782. Snow-ploughs. TURNER, P. June 19, 1953 [June 20, 1952], No. 15597/52. Class 107. A snow-plough for use with a motor vehicle comprises a " pusher " formed from two similar rectangular flanged plates 12, 13 hinged together by the adjacent flanges on two of the shorter sides and thus capable of being folded into a box (shown partly open in Fig. 6) which contains the various struts and stays. Four struts secured in pairs 15, 16 and 14, 17 to form two V's have their extremities attached to the flanges of opposite longer edges of the pusher plates near the hinge and their apices secured to or engaging with the bumper or other part of the vehicle at spaced points (members 24). Four side stays are detachably connected to the flanges of opposite longer edges of both pusher plates at points (27) remote from the hinge and each is connected detachably to one of the four struts. As shown, the side struts are in pairs (only the upper ones being visible in Fig. 2) one member 20 of each pair being short and the other member (18, 18a) being longer so that each pair can be used (full lines, Fig. 2) together to set up the pushers as shown, or the short ones can be used alone (chain-dotted lines) to form a V- shaped plough. By pivoting the combined strut 18-20 from the bolt-hole 26a, and using the set-up shown chain-dotted on the left, an inclined plough is formed. Similarly, the same effect with the plough obliquely disposed on the other hand can be obtained by using strut 20 alone on the right and the combined struts in the auxiliary hole on the left.

Title: Improved driving connection between a motor driven gear wheel and a wheel of a vehicle driven thereby
IPC: F16D3/00
Filed: 1927-06-11
Abstract: 297,013. British Thomson-Houston Co., Ltd., (General Electric Co.). June 11, 1927. Universal joints. - Driving and driven wheels, such as a motor-driven spur-wheel and track-wheel of an electric locomotive, are coupled by linkage which allows lateral, axial, and tilting movements and comprises a rock shaft carried in bearings on, say, the trackwheel, and having directly connected to it two links in driving-engagement with the spur-wheel at fixed distances from its axis. The spur-wheel 15, Fig. 1, is mounted on a quill-shaft 16 carried in bearings 17 in the spring-borne casing 13 of a twin driving-motor, and is driven by pinions 14. Pairs of links 23, which pass between the spokes of the track-wheel 10, are ball-jointed to cylindrical bearing-members 24<a>, slidable in apertures 24 in the wheel 15, and also are pivoted to duplicated shafts 21 on axes 23<a> transverse thereto. The shafts 21 turn in bearings 22 on the wheel 10, so that, by combined rotations about the joints 23b, pivots 23<a> and bearings 22, with sliding of the members 24<a>, all motions are accommodated. In place of the two shafts 21 a single diametrical yoke 21, apertured to clear the driving-axle 11, may be used. In a modification links 42, 43. Fig. 6, are integral with the floating rock shaft 40, 41 and are pivoted, as at 43a, to the wheel 15, the shafts being ball-jointed to arms 44 connected to the track-wheel 10 by further balljoints 44<b>. The slight yield of the shaft absorbs shock. Specification 275,731 is referred to.

Abstract: 333,629. Standard Telephone.s &. Cables, Ltd., Smith, C. P., and Snell, M. S. May 18, 1929. Oscillating machines. - In a step-by-step switch, the drive is transmitted to the shaft from the operating armature through a magnetic clutch, and auxiliary means are provided to determine accurately the length of the stroke. As shown in Figs. 1 and 2, a double magnet 5 is employed with an armature in two parts 3, 4 located on either side of a magnetic disc 1 mounted on the wiper shaft 2. When the magnet 5 is energized the magnetic flux through the armature 3, 4 and the disc 1 causes them to adhere and rotate the shaft 2 one step, the length of which is determined by a roller 7 which cooperates with notches on the disc. As shown in Figs. 3 and 4, a single magnet 2 is employed, the shaft 1 serving as a core, with a star-shaped pole-piece 3 acting on a correspondingly-shaped armature 4 carried by a non-magnetic plate 5 bearing on a collar 11 on the shaft. A magnetic cage carrying the wipers and comprising bars 6 and a spider 8 bears on a collar 10 and can rotate freely. When the magnet is energized, the armature 4 takes a step in an anti-clockwise direction, Fig. 4, carrying the cage with it duo to the magnetic flux across the gap 7. A roller 22 similar to the roller 7, Fig. 2, is carried by a rocker 20 fixed to the cage and co-operates with a notched disc 16 squared on the shaft 1. Interrupter springs 24 may be carried by the disc 16 and operated by an arm 12 on the armature 4.

Abstract: 585,030. Automatic braking control systems. TOMLINSON, A. V. (Westinghouse Air Brake Co.). Sept. 30, 1943, No. 16062. [Class 103 (i)] [Also in Groups XXXV and XXXVIII] Apparatus for detecting the rate of change of speed of a rotary member comprises two coaxial discs carrying an equal number of permanent magnets. Only one disc is coupled to the rotary member but the other rotates therewith at the same speed unless the rate of change of speed of the rotary member exceeds a predetermined value. The voltage induced in a stationary wind- Ing by the magnets controls the degree of application of the brakes of a vehicle. In the form shown, disc 21 carrying a number of U-shaped magnets 27 rotates with the vehicle axle 13 and the loosely mounted disc 17 carrying similar magnets. A flywheel 31 is also carried around with it by magnetic attraction as long as no sudden speed changes occur. Under these conditions the voltages induced in the stationary winding 45 by the magnets on the two discs cancel out but when the application of the brake becomes sufficient to cause the wheels to slip a voltage is induced in winding 45 by the magnets on disc 17 which continues its rotation by its own momentum, and this voltage, rectified at 63, energizes the pick up winding a of relay 64 and enables the magnet valve 65 to reduce the pressure applied to the brake cylinder 72. When this pressure falls pressure responsive switch . 77, which closed as soon as the brakes applying lever 68a was actuated, reopens. The wheels also regain vehicle speed whereupon relay 64 reopens. The brakes can then be re-applied until slipping again occurs. The winding 45 can be carried by a piston in an air cylinder in the pneumatic system so that it is only brought near the magnets on application of the brakes.

Title: Improvements in electrical circuits
IPC: H03K19/185
Filed: 1957-05-21
Abstract: 868,718. Dielectric pulse-storage circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 21, 1957 [May 22, 1956], No. 16106/57. Class 40 (9). [Also in Group XXXVI] An electrical circuit comprises a capacitor consisting of ferroelectric material mounted between two electrodes through one of which a current may be passed to heat the ferroelectric material and thus cause a current, the polarity of which depends on the initial state of polarization of the material, to flow between the electrodes and means for detecting the current. In the embodiments shown the electrodes are in the form of narrow strips disposed at rightangles to each other on opposite faces of a plate of crystalline barium titanate. The electrode through which the heating current is passed is preferably waisted where it intersects the projection of the other electrode (see Fig. 6). Fig. 4 shows a memory circuit in which the barium titanate is polarized in one or other direction by application of a positive or negative voltage to electrode 14 via switch 20. When the switch is returned to its central earthed position the titanate retains a remanent polarization. The state of polarization may then be determined by passing a reading out current pulse of either polarity along the electrode. The initial rapid but small rise in temperature of the neighbouring dielectric reduces the polarization thus causing a current pulse the polarity of which depends solely on the direction of polarization of the titanate to flow through the capacitor 46. When the reading out pulse terminates the device returns to its original state of remanent polarization, thus giving non-destructive read out. The operation of an " exclusive or " circuit (Fig. 5) utilizing the same principle is as follows. The titanate crystal is polarized via switch 20 as before. Batteries 62, 64 represent pulse sources connected to opposite ends of electrode 12. When a pulse of either polarity is delivered from one source only a heating current is generated causing a read out signal current to flow through capacitor 46. However, when pulses of similar polarity are received simu1- taneously from both sources no heating occurs and the output signal is zero. In each of the above circuits an additional charging current flows through the ferroelectric material when a read out signal is applied. This is due to the potential of the part of the electrode 12 at the intersection with electrode 14 being raised above earth by the current along it. The current is, however, small compared with the current due to change of polarization with temperature and its only effect is to alter the magnitude of the pulses. A similar effect occurs in the Fig. 5 circuit when pulses are received simultaneously from both sources and gives rise to spurious output signals, which are however small compared with the true read-out signals. The effect is reduced by the electrode configuration shown in Fig. 6 which gives the maximum heating effect for a given applied voltage.
