Title: Improvements in or relating to buffers and draw gear for vehicles, particularly for tramcars and other rail vehicles
IPC: B61G11/02
Filed: 1929-12-16
Abstract: 338,037. Union Construction & Finance Co., Ltd., Dowling, H. T., Adams, A. E., and Bastock, S. J. Dec. 16, 1929. Buffers; combined buffer and drawgear.-In a tramcar or similar vehicle a plate or leaf spring buffer 10 supported in advance of the headstock 14 is connected by means of a draw-bar 26 with a second or reinforcing spring 31 disposed beneath the vehicle, the latter spring being designed to take drawing stresses and any direct or longitudinal shocks received by the buffer while a transverse or glancing blow is absorbed by that half of the buffer upon which it falls. In the construction shown in Figs. 1 and 2 the front buffer comprises two arcuate leaf-springs 10 connected one on each side of a cross-head 11, which is secured by bolt 24 to the draw-bar 26 and is formed with upper and lower tongues 20, 21 slidable in relation to the headstock 14 and to a guide 22 secured thereto. A hole 19 in the cross-head 11 serves for the attachment of a shackle or like coupling. At its rear end 29 the draw-bar 26 is pivoted to a clamp 30 embracing the centre of the spring 31, while the ends of the springs 31 are received in boxes or castings 31<1>, Fig. 3, which are secured to frame members 34, 35 and have a fixed near wall 32 and a slidable front wall 33. Instead of forming the buffer in two halves it may consist of a single spring having either, several leaves or, as shown in Fig. 8, a single leaf 38 connected at its centre to the drawbar 26; in all constructions, however, the ends of the springs have a free sliding contact with the vehicle body, e.g., by means of pegs 15 bearing against wearing-plates 16.

Title: Apparatus for simulating the playing of golf strokes
IPC: A63B69/36
Filed: 1971-11-01
Abstract: 1377605 Golf practising means J R CHRISTOPHERS 1 Nov 1971 [11 Aug 1970 30 Nov 1970] 38684/70 and 51774/70 Heading A6D [Also in Divisions H3 and H5] In apparatus for simulating the playing of golf strokes, the flight of the ball 13, after it has been struck by the club, is monitored both as to its height, and to its lateral deviation from a desired path, by means of respective vertical and horizontal arrays of photodetectors 25 and 24. These determine the two dimensional position where the ball passes through a curtain of light 22 produced by an array of projectors 21. By means of internally generated counts and ramp functions simulating flight paths, an indication may be given at 16 of whether the ball has been struck high or low or to the left or to the right and by how much. An indication is also given of what the range of the simulated shot is and what the range from the landing place of the simulated shot to the next hole may be. Means are also provided on the console 15 for insertion by the player of data as to which club he has selected and what is the range to the next hole. When the ball 13 is placed upon the tee its shadow is cast upon a detector 17 whereby, when the club strikes the ball, the detector is uncovered and produces a signal indicating the start of the flight of a ball. The signal from array of detectors 25 is converted into a height indication which is compared at comparator 36 Fig. 2A with the height which should have been recorded with the selected club, the comparison producing a high or low display 32. The lateral deviation array of detectors 24 produces an output giving the left or right deviation display at 31. The height indication from array 25 also causes the start of a variable slope function from generator 37, said function stopping when the ball is detected by a stop array of detectors 26. The level reached by the function is stored at 39 Fig. 2D and compared with a linear ramp produced by a range integrator generator 42. When the comparison determines equality a range gate signal causes closure of a gate 41 passing pulses from oscillator 44 to a counter 45 whereby the range of the ball is calculated and displayed at 34. The lateral deviation of the landing of the -ball from the desired position will depend not only on the deviation as detected by array 24 but also onthe spin of the ball, which spin is determined by a photodetector receiving the reflections from a reflective stripe painted upon the spinning ball. The spin detector 58 therefore feeds its output to a calculating unit 60 which produces a signal fed to a divider 47 also receiving the output from the left or right display 31. The output of divider 47 is fed to a deviation counter 48 to give rise to a width display 33 of the lateral landing deviation of the ball.

Title: Coin-operated lock
IPC: G07F17/14
Filed: 1969-08-01
Abstract: 1281926 Coin-freed locks SCHLOSSFABRIK SCHULTE-SCHLAGBAUM AG 1 Aug 1969 [19 April 1969] 38777/69 Heading G4V A coin-freed lock includes a bolt adapted to support an inserted coin, a latch co-operating with the bolt to prevent movement thereof in the absence of a coin but moved aside by a coin to free the bolt, a stepped plate co-operating with the latch in the presence of an oversized coin to prevent movement of the bolt, and a coin-return mechanism. The bolt 16 has a recess 20 with which a spring-loaded latch 17 co-operates to prevent throwing of the bolt by a key-operated barrel lock in the absence of a coin 28. An inserted coin is supported by a fixed stop 27 and a stop 29, on a plate 30 carried from the bolt by a leaf spring B. In operation, the stop 29 moves the cam forwardly with the bolt to lift the latch 17. On clearing the fixed stop 27, the coin falls on to an abutment 9 and is held there by a plate 36 movable with the bolt. The key may be removed from the barrel lock in the extended position of the bolt. On retracting the bolt, the coin falls from abutment 9 into a cash box or is returned to the user. Coin return.-The plate 30 may be moved away from the bolt by a push button to withdraw stop 29, projecting through an aperture in the bolt, to allow a coin to fall to a return shoot. Fraud preventing.-A stepped plate 21 is fixed to the bolt. If the latch 17 is raised by an instrument inserted through coin slot 26, it engages step 22, 23 or 24 to prevent full movement of the bolt. Likewise, insertion of an oversized coin raises the latch into engagement with step 22. An undersized coin falls between the stops 27, 29.

Title: Device for controlling the pulsating operation of electromagnets in knitting machines

Filed: 1975-09-29
Abstract: 1527911 Transistor switching circuit ELITEX 29 Sept 1975 [28 Sept 1974] 39725/75 Heading H3T In a circuit to control the energizing of an electromagnet, e.g. in a knitting machine, a capacitor C, the coil M of an electromagnet, and a control element, e.g. transistor T 1 , are connected in series in that order, with a first voltage source U b2  applied across capacitor C via a blocking diode D 2 , and with a switchable stabilized current circuit controlling the current through the control element: a second higher voltage source is led in via a switch element, e.g. thyristor T y  to the connection between the control element T 1  and coil M. After initial charging of C via thyristor T y  to second source voltage U b1 , input of a control signal at B, amplified at terminal 9 allows integrated amplifier ÁA 723 to be energized, supplying base current to transistor T 1 . C then discharges rapidly via coil M, transistor T 1  and resistor R 1 , the current overshooting to a peak, (Fig. 2, not shown), accelerating closure of the magnet armature. In the stabilizing circuit the voltage across R 1  applied to inverting input 2 of amplifier ÁA 723 is compared with the adjustable fraction, set by R 5 , of a reference voltage supplied by the amplifier at terminal 4 and tapped off to non-inverting input 3; at this stage capacitor C, holds down the voltage across R 1 , allowing the current through C and M to overshoot before falling. After time t 1  (Fig. 2, not shown), C will have discharged sufficiently to allow voltage source U b2  to begin to feed current through diode D 2 , and shortly afterwards at time t 2  when C, has charged to allow the full volt-drop to appear across R 1 , the coil current is stabilized at a constant value determined by R 5 . Finally the signal is removed from B, cutting off the amplifier and transistor T 1 , and at the same time a pulse G to thyristor T y  allows source U b1  to supply reverse current through coil M, shunted in part by diode D 1  and resistor R 2 , to charge C, the current continuing in damped oscillation, via circuit C, M, R 3  &c. The current reversal removes remanent magnetism in the electromagnet, ensuring that its armature drops out. The control and switching elements may be other than semi-conductor devices.
