Title: Improvements relating to braking systems for vehicles
Inventor: EATON MAURICE BARRY
IPC: B61H13/32
Filed: 1964-10-30
Abstract: 1,080,757. Regulating braking in accordance with load. GIRLING Ltd. Oct. 11, 1965 [Oct. 30, 1964; Nov. 4, 1964; Nov. 5, 1964; March 2, 1965 (2)], Nos. 44275/64, 45040/64, 45148/64, 8755/65 and 8756/65. Heading F2E. The actuating means for a rail vehicle brake comprises a lever 11 acted upon at 10 by a brake applying force and connected through mechanism to a lever 18 coupled at 17 to the brake, the mechanism incorporating a roller 16 co-operating with a surface 24 tiltable in accordance with the vehicle load to vary the mechanical advantage of the mechanism. The mechanism is shown in the brake application position, when a pivoted toothed bar 28 engages tiltable surface carrier 25 to prevent its movement; in the brake release position the lever 11 abuts a stop 32 to withdraw the bar 28. To provide some lost motion the roller 16 is clear of the surface 24 when the brake is released, the clearance being a maximum when the vehicle is unladen and reduced as the vehicle is loaded. The Specification describes the mechanism (Fig. 7, not shown) whereby a shaft is rotated in accordance with the vehicle load, and apparatus (Fig. 4, not shown), whereby the loading of two axles of the vehicle are compared and the loading of only the more lightly loaded axle is made to vary the inclination of the surface 24 and control the braking on the wheels of both axles. The brakes are operable by vacuum motor and a compresser air motor, lost motion connection linkages are described which allow the motors to operate independently.

The data pulse output from magnetic read head 20 of, for example, a tape system is clocked using clock pulses on another track, the clock pulses being recorded intermediate the data pulses to avoid skew problems; alternatively, the clock detector circuit may be responsive to the crossovers in the clock output from 22, so that in any case the clocking delay is a fixed fraction of the clock period independent of the tape speed. As shown, data pulses set 26 which is then reset approximately ¢ clock period later to give an output.

Abstract: 1,106,771. Arranging and feeding tobacco leaves. MOLINS ORGANISATION Ltd. 5 Nov., 1965 [6 Nov., 1964], No. 45409/64. Heading A2C. Apparatus for arranging cut or whole leaves of tobacco so that their longer dimensions are all orientated in one direction comprises two sets of opposed surfaces 8 and 12-15, the set 12-15 consisting.of a plurality of rotatable brushes each one of which is rotated at a speed up to 20% faster than its adjacent predecessor. The roller 12 is rotated at a correspondingly higher speed than the surface 8 which consists of a conveyer running over rollers 10 and 11 and driven roller 9. In a second embodiment the surface 8 is replaced by a second set of rotary brushes, Fig. 3 (not shown). The tobacco leaves are fed from a hopper 1 with the assistance of a rotary rake 5. The leaves are fed on to a tray 16 which reciprocates beneath two pivotable members 17 and 18 made from material with a high coefficient of friction. The surface of the tray 16 has a low coefficient of friction. As the tray travels one way leaves are deposited thereon. On the return stroke one of the members 17 or 18 is lowered on to the tray and as the tray moves away to collect a further batch of leaves, the leaves formerly on the tray are stripped off and fall on to a conveyer 21. Nozzles may be provided under the opposed sets of surfaces arranged to deliver an air blast to assist in correctly depositing the leaves on the tray as the tray changes direction, Fig. 4 (not shown).

Abstract: 899,136. Magnetic amplifiers. POSTMASTER GENERAL. Jan. 1, 1960 [Oct. 2, 1958], No. 45514/61. Divided out of 899,134. Class 40 (9). [Also in Group XL (c)] In an apparatus for modulating and demodulating amplitude modulated pulses in exchange terminal equipment (see Group XL (c)), the modulator, Fig. 1, includes a saturable core inductor having a substantially rectangular hysteresis loop and provided with biasing windings 1, audio signal input windings 2, a pulse input winding 3 and an output winding 4. A two-wire line supplies audio frequency signals to the windings 2, and is supplied with direct current by a battery B via resistors R2 and the windings 1, the windings 1 being such that the core normally is saturated. The winding 3 is provided with pulses from a source PS1 and the output winding 4 is connected via a rectifier MR to common highway H1 having a transistor amplifier VT1. When a pulse is supplied from the source PS1 and a signal is present on the winding 2, the core becomes unsaturated, thus producing a pulse in the output winding 4 and this pulse is amplitude modulated by the audio signal. The windings 1 and 2 may be combined. Specification 866,429 also is referred to.

Abstract: 1482812 Mixing liquids CIBA-GEIGY AG 21 Oct 1974 [2 Nov 1973] 45524/74 Heading B1C [Also in Division G3] Apparatus for controlling the temperature of a heat exchange liquid for a calorimeter W by mixing with a hotter or cooler liquid comprises a centrifugal pump 53 for circulating the liquid and two containers 51, 52 containing liquid controlled at temperatures respectively below and above the working temperature by cooling and heating coils 59, 58 respectively. The pump shaft 55 extends into the curtains to carry circulating propellers 55c, 55e within draft tubes 57a, 57b and is rotated by a motor 56. The containers are connected to the section of the pump through the shaft bearings and passages 55a, 66 and 55b, 67 and to the discharge side through conduits 62, 63 having respective valves 62a, 63a. A regulator 64 compares the desired temperature of the heat exchange liquid pre-set at 65 with the active value sensed at 64a and with the calorimeter temperature sensed at 64b and if necessary opens valve 62a or 63a to add colder or hotter liquid to the working liquid passing through the pump. The corrective liquid is preferably added in small increments by opening and closing the valves for brief periods of constant duration, the intervals between the periods being variable. Preferably the temperature in containers 51, 52 are not constant but are maintained at a constant difference from the temperature in the working circuit by regulators 60, 61 in cooperation with sensors 60a, 60b, 61a.
