Title: Improvements in or relating to a device for braking the rear inner wheel of a vehicle when taking a curve
IPC: B60T8/24
Filed: 1961-06-20
Abstract: 960,264. Steering and braking vehicles. FABBRICA ITALIANA MAGNETI MARELLI S.p.A. June 20, 1961 [June 24, 1960], No. 22180/61. Heading B7H. [Also in Division F2] A device for braking the rear wheel on the inner side of the steered curve of a vehicle during manipulation of the steering comprises two control means for the admission and discharge of fluid under pressure to the braking means of the two rear wheels. The control means are connected with the movable steering elements in such manner that the admission of the fluid to the brake of either wheel is possible only when steering is performed with the curvature of the steered path having its centre on the side of the wheel that is braked. As shown in Fig. 1, pneumatic rear wheel braking cylinders 5, 6 are connected to a distributer A via 3-way automatic valves 13, 14. The distributer is fed from a pressure air reservoir 4 and is controlled by the steering via a rod 3 and actuating lever 2. Normal braking of the rear wheels is effected by a conduit 7. The distributer, Fig. 2, comprises two valves arranged on parallel axes and each consisting of a closure member 21 pressed by a spring 22 against a seat 23. A member 24 through its hollow extension 25 acts to lift the member 21 from its seat 23 against the action of a return spring 25<SP>1</SP> and is controlled through a helical spring 31 by a cup 30 which presents a loose roller 32 co-operating with a cam face 33 formed integrally with a control shaft 20 that is rotated by the lever 2. The fitting 34 is connected to the pressure reservoir 4 and the fittings 38, 39 to conduits 10, 11 (Fig. 1). When the lever 2 is in its mid-position both of the valves are inoperative, the chambers 36, 37 being in communication with the atmosphere through radial holes 26 and a slot 27. Movement of the lever 2 in either direction actuates one of the valves. The corresponding cup 30 is lifted by the cam and acts on the element 24 through the spring 31 so as to lift the closure member 21 with the extension 25, the bore of the latter being sealed by the member 21 and cutting of communication of the corresponding chamber 36 or 37 with atmosphere. Chamber 36 or 37 is therefore put into communication with the reservoir 4 to effect braking of the rear wheel internal to the curve.

Abstract: 1,136,782. Transferring sliver cans between machines. INSTITUT FUR TEXTILMASCHINEN. 23 May, 1966, No. 22894/66. Heading D1F. While sliver is fed to a processing machine 2 from at least two rows 31, 32 of cans, a reserve row 10a of cans filled with sliver from machine 1 is formed behind row 32, and when the cans in row 31 are emptied the reserve row 10a is pushed forward and thus pushes the cans in row 31 on to track 5a from whence the cans are returned to the sliver filling position 10. Can track 5a is at a higher level than can track 4b while can tracks 6 and 7 are inclined. A pusher 22 is secured to nut 23 on threaded spindle 24 which can be rotated by motor 25 to cause the pusher to move the cans in rows 10a, 32 and 31 one row forwards. Pivoted bolts are provided to hold the cans in row 32 on the inclined slope. Empty cans on track 5a are pushed down track 7 by means of pusher 26 moved by motor 29 through nut 27 and spindle 28. A can is moved from a reserve position 9 into the filling position by pusher 8 operated by crank 12, and held in the filling position by spring pressed rollers 42, 43 and roller 44. A filled can, after it has been pushed out of the filling position by an incoming can, is pushed onto the inclined slope 6 by rod 16 pivoted by cam 18 through transmission 19 and bevel wheel assembly 17.

Abstract: 1,190,414. Transistor switching circuits. DANA LABORATORIES Inc. 17 May, 1967 [30 Jan., 1967], No. 22925/67. Heading H3T. [Also in Division G4] In a switching circuit, having a transistor 38 with an emitter resistor 50, 52 and a control signal means connected to the base for providing a two-state ON-OFF signal of substantially constant current for the ON state and of substantially constant voltage of a value less than the common potential 30 for the OFF state, the ON signal level is at least equal to the collector potential plus the bias potential across the base collector junction such that in the ON condition the base-collector current is greater than the base-emitter current and the collector and emitter voltages are substantially equal. In the digital to analogue circuit shown a separate switching circuit 1-4 is used to convert decimal binary values of 1, 2, 4 and 8 to analogue representations to be summed at the input point 18 of an operational amplifier 20. When the binary input signal at 10 is zero the output from an amplifier 32 is low, say-1 or 2 volts. This causes current to pass via resistor 42 and diode 36 which is forward biased so that the base of transistor 38 is low and transistor 38 is biased OFF. When a binary signal occurs at 10 this causes the output of amplifier 32 to be high. This biases the diode 36 OFF and applies a voltage + V R  + V B  greater than the collector voltage of transistor 38 so that the transistor 38 turns ON and operates in the saturated condition. The value of the current through a precision resistor 50 is then an analogue representative of the binary input at 10. The value of the analogue current may be set by adjustment to the amplifier 46 to alter the collector potential or by variation of the precision resistor 50. The diode 36 may be replaced by a transistor. In a modification (Fig. 2, not shown) the output of the amplifier 46 (54) is set by a switch (60) to connect a different bias voltage to this amplifier (54). Alternatively the switch (60) may be replaced by a fixed or continuously varying signal source such that the analogue output may be modulated or multiplied in the required manner. The transistor 38 has a high alpha (current transfer) inverse characteristic when ON and a high alpha forward characteristic when OFF.
