Title: Apparatus for automatically opening and closing barriers at level crossings of railways
IPC: B61L29/20
Filed: 1926-03-15
Abstract: 260,841. Rizzi, G., and Cerutti, F. March 15, 1926. Operating and controlling gates and barriers hydraulically and pneumatically, and by treadles and the like; indicating and signalling operation of gates and barriers. - Each barrier 1 at a level crossing of a railway track is subjected to the action of a pair of ram pistons 3, 11 Fig. 1, the piston 3 being operated by a treadle - operated compressor 6 to close (or open) the barrier, the piston 11 being operated to release the barrier, so that it can close (or open), by means of a treadle-operated piston 14' positioned on the other side of the barrier. When the treadle 7 is pressed down by the train it causes fluid pressure to pass through the conduit 5 into the cylinder 2. The piston 3 then moves upwardly and closes the barrier through a rod 4. The barrier is secured in the horizontal position by a pawl 8 engaging with a lever 9. After passing the gate the train depresses the treadle 15<1> and pressure fluid lifts the piston 11 and releases the pawl 8. As the counterweight 13 falls to open the barrier pressure fluid is driven from the cylinder 2 into the compressor 6. The process is repeated when the train approaches the gate in the opposite direction and operates the compressors 6<1>, 14. In a modified construction, the barrier is secured in the open position and the first treadle causes its release, when it closes by gravity. The second treadle when depressed restores the gate to its open position. In other forms, the cylinders are provided with overflow receptacles. In the compressor shown in Fig. b, the treadle 15, when depressed, moves the piston 20 through a lever 17, pawl 18 and toothed pistonrod 19, a second pawl 21 preventing the return of the piston. A cam-surface 22 at the end of the piston-rod lifts the pawls when the piston reaches its inner dead point, the pawls being moved laterally by a spring on to the smooth side of the piston-rod to allow the piston to be returned. An expansion chamber may be arranged between the compressor and the piston operating the barrier. In order to avoid the shock caused by the depression of a pedal by a vehicle wheel the arrangement shown in Fig. 11 is employed. A side rail 30 is connected with an arm 31 supported by a spring 32 and pressed against the rail by a spring 32<1>, and the arm is pivotally connected to a rod 33 adapted to operate the compressor through lever mechanism. A stop pin 39 positioned on one side of the rod 33, as shown, provides for the operation of the compressor only when the train is moving in the direction of the arrow F. The movement and position of the barrier may be suitably indicated by a bell or signalling device.

Title: Supercharger control system
IPC: F02B33/00
Filed: 1952-03-24
Abstract: 715,290. Variable-speed gear. GARRETT CORPORATION. March 24, 1952 [April 27, 1951], No. 7494/52.. Class 80 (2) [Also in Group XXVI] Two variable-speed gears are connected in series between a centrifugal blower (e.g. for an aircraft pressure cabin) and the driving engine the ratio changes of the first gear being controlled by means responsive to engine speed changes and the ratio changes of the second gear being controlled by means responsive to a condition of the discharge from the blower. As shown a two-ratio counter-shaft gear driven from an engine shaft 10 comprises a gear pair 48, 11b and a higher ratio gear pair 47, 11a driving a shaft 11. The wheel 47 is rotatably mounted on the shaft 10 but may be non- rotatably connected thereto by an hydraulically actuated clutch 50 whereupon a one-way clutch 49 in the wheel 48 overruns. Oil supplied under pressure from a pump 26, driven from the wheel 11a, is admitted to a chamber 51 to engage the clutch 50 under the control of a valve 55 which is actuated by speed responsive means driven through bevel wheels 57, 59 from the shaft 10. The shaft 11 drives the planet carrier 12b of a continuously variable epicyclic gear 12, the sun wheel 12d of which drives the final output shaft carrying an impeller 13a of a blower, and the reaction annulus 12e of which is connected by gears 14a, 14b to a gear pump 14. The output of the pump 14 is controlled by a throttling valve 20 responsive to changes in the air flow from the blower through a venturi 25 the differential pressure developed therein acting on a valve 17 controlling the flow of oil through a chamber 16a having a diaphragm 21 which actuates the valve 20. A pressure-limiting valve 22 prevents over-speeding of the blower. When the engine is started and before the pump 26 builds up pressure there will be very little reaction supplied by the pump 14 to the gear 12e. The blower therefore starts gradually. The increasing pressure actuates the clutch 50 and the shaft 11 is driven through the high ratio gear pair. When the engine attains its normal speed the valve 55 functions to disengage the clutch 50 and the shaft 11 is driven through the low ratio gear pair. The speed of the blower is thus maintained relatively constant over a large engine speed range.

Title: Improvements in and relating to coil winding machines
IPC: B65H59/38
Filed: 1959-03-06
Abstract: 935,084. Coil-winding machines. T. H. PALMER. March 7, 1960 [March 6, 1959; Nov. 10, 1959], Nos. 7794/59 and 38140/59. Class 120 (2). A coil winding machine comprises a rotatable spindle-member for a spool or other coil former, a member for guiding wire &c. on to the spool &c., electric means for relatively reciprocating one of the two members against means biasing them to relatively predetermined positions so as to vary, in accordance with the degree of energization thereof, the relative positions of the two members, and voltage-generating means for energizing the reciprocating means with cyclically variable voltage to cause one member to be reciprocated relatively to the other. In Fig. 1, the guide 35 is fixed and the spool 33 is rotated by a motor 13 and reciprocated by a spindle 10 according to the energization of an actuator 17 against means which bias the spindle so that the spool occupies a central position relatively to the guide. The actuator is energized from a circular potentiometer 25, the arm of which is rotated from the motor 13 by gearing 31, 32. A rheostat 37 is adjusted so that a maximum voltage is supplied to the actuator sufficient to displace the spool a distance equal to half the length of the coil it is desired to wind, an ammeter 38 indicating the length of the coil being wound; the gearing 31, 32 is chosen so that the number of revolutions made by spindle 10 while the potentiometer-arm rotates through half a revolution equals the desired number of turns per layer of coil. In another form, the potentiometer-arm is driven by an electric motor of which the armature is supplied from the armature of a tacho-generator driven by motor 13, the speed of rotation of the contacts being controlled by field-regulators in the circuit between the armatures. In other forms, an auxiliary guide-member 50, Fig. 3, is provided biased to a position in front of the main guide 35 to provide for minor variations, e.g. in the speed of the axial movement of the spindle 10 and in the thickness of the wire; this auxiliary guide is coupled to a member 49 in a transducer 48 in circuit with a reversing- switch 47 operated by a cam 53 in the driving- connection to the arm 30. In Fig. 3, the arm is driven by a variable-speed motor 45 which is controlled by the signals from the transducer; in another form, the arm is driven as in Fig. 1 from the motor 13 which rotates the spool and the signals of the transducer are fed into the amplifier 21 through which the actuator 17 is supplied. In a further form, the actuator has a second winding opposed to that of the first supplied by an amplifier fed from a second potentiometer coupled to the first. In variations, the circular type potentiometer may be replaced by an electronic generator, and to produce special windings, other kinds of potentiometer may be used or the arm, instead of being driven directly by the motor, may be driven by the follower of a cam driven by the motor.
