Title: Improvements in means for preventing unauthorized operation of brake levers on motorvehicles
IPC: B60R25/00
Filed: 1932-09-14
Abstract: 407,695. Lockable control levers. HEARNE, T., 29, Byron Road, North Wembley, Middlesex. Sept. 14, 1932, No. 25501. [Class 79 (iii).] Unauthorized release of a hand brake-control of the " lever-and-quadrant type on a motor vehicle is prevented by removal of a keypiece associated with the pull or push rod between the grip lever on the brake control handle and the locking detent. In the form shown in Fig. 4, in which the detent 3 is released by a thrust on the part 21, the transmission means comprises a tripartite rod 13, 14, 15 in a tubular casing 17 connected at its upper end to the grip lever 16. The upper and lower parts 14, 15, which are threaded for engagement with the casing, are connected by the intermediate keypiece 13 so that when this is in position the part 14 can be rotated through the medium of the part 15, the keypiece being formed with a square end 23 for engagement with the part 15 and an irregular keylike end 24 for engagement with the correspondingly shaped end of the part 14. As shown, the keypiece 13 has been removed through an opening 19 in the side of the casing after the part 14 has been withdrawn into the casing out of contact with the pin 21. To render the actuating means operative, the upper part 15 is loosened by unscrewing it from the casing, the keypiece is inserted through the aperture 19 and the part 15 is then screwed down again, this time turning the lower part 14 so that the end 20 thereof threads into the casing and is brought into a position to transmit a thrust to the pin 21 when the handle 16 is gripped. In the arrangement shown in Fig. 2, in which the detent is released by a pull on the rod 2, the head 2<a> of the rod enters a casing 8 pivoted by pins 9 in the forked arm of the grip lever and is normally coupled therein, by means of a screw or pin 9<a>, to a keypiece 7. The keypiece, together with one of the associated parts, is formed with complementary projections and recesses &c. and is disconnected and removed to render the actuating means inoperative. Loss of the pin 9<a> is prevented by a keeper plate 12 on the keypiece. In either form of the invention the quadrant and detent and other parts may be enclosed to render them inaccessible. The Provisional Specification describes a modification of the form shown in Fig. 4 wherein the lower end of the part 14 is hollowed out and internally as well as externally threaded so that when screwed down it effects connection both with the casing and with a part on the detent replacing the pin 21.

Title: Improvements in electric regulator control systems
Inventor: HAGLOF NILS JOHAN EDVARD
IPC: B65H23/08
Filed: 1958-08-11
Abstract: 871,759. Automatic tension control systems. FULLER ELECTRIC Ltd. July 31, 1959 [Aug. 11, 1958], No. 25676/58. Class 38 (4). [Also in Group XXXVII] Paper web 1 is drawn from reel 2 coupled to D.C. motor 3 which is connected to generator 4, the tension in the web being detected by roll 6 mounted on spring-biased lever 7. When the tension in the web decreases from a desired value, and the lever 7 swings in the direction of the arrow A, tachometer generator 13 is rotated to supply a control winding of transductor regulator 15 so that the excitation of a generator field winding 16 is reduced. At the same time, contact 8 is displaced with regard to contact 20, and a further control winding of the regulator is energized to reduce further the output to the winding 16. As a result, the output of generator 4 decreases, the speed of the motor 3 is reduced, and the web-tension is restored to the desired value. If the tension in the web increases, the resultant correction provided by the control windings of the regulator increases the speed of the driving motor. A feed-back component for the regulator is provided by transformer 23 having its primary winding connected across the armature of the motor 3. This enables a high rate-of-change of corrective torque to be applied to the reel when the latter has a high inertia, and a reduced rate-of-change at smaller reel diameters. Specification 871,760 is referred to.
Patent GB-616137-A (GB)
Title: Mechanical change-speed transmission for locomotion engines of great power
IPC: F16H61/02
Filed: 1946-08-28
Abstract: 616,137. Change-speed gear. COPONAT, A. C. M. H. Aug. 28, 1946, No. 25842. Convention date, Nov. 7, 1944. [Class 80 (ii)] In the transmission of a heavy tracked or rail vehicle, four or eight ratio-shifts in widelyspaced geometrical progression are obtained without power interruption up or down, by the provision of two complete identical two- or four-ratio epicyclic gears 63, 64, driven in parallel at the same speed through friction clutches 13, 13<1>, interlocked by a lever 20 for alternate operation, and connected to the parallel driven shaft 48 through different-sized toothed wheels 39, 41 respectively, the ratio of which is that of the geometrical progression, whilst the ratio between the individual steps of each gear is the square of that ratio. Thus, whilst one gear 63 or 64 is driving, the other 64 or 63 is idle and can be changed for the next shift up or down without difficulty, the shift being subsequently rendered effective instantaneously (e.g. in one-fifth of a second) by changing over the friction clutches 13, 13<1>. The driving wheels 12, 121 of the frictionclutches are simultaneously driven at the same speed through a bevel or planetary reverse-gear 4 by one or more engine shafts 1, each having a fluid-coupling 3. The two identical changespeed gears shown each comprises in series stepped and simple planet trains 33, 36, each yielding solid and reduced drives by clutching or holding their ring-gears by means of two sliding dog clutch-detents, e.g. 28, with synchronizing cones 24, operated directly, by power or automatically through striker-rods 42, 43 and 44, 45, so that each gear provides three reduced ratios and direct-drive between its respective driving shaft 63 or 64 and driven wheel 39 or 41, which latter wheels, through idlers, thus impart eight speeds to the final parallel driven shaft 48. The latter drives track-sprockets through two three-element planet trains, the ring-gears 49, 49<1> of which have external teeth meshing respectively through a reversing idler 55 and directly with a parallel shaft 54 which can be held stationary for straight travel with final speed reduced in the two trains, or be driven in either direction from a constantly driven wheel 56 and a mechanical, electric or hydraulic variable control 57 (not described), to impart controlled speed differences to the ring-gears for steering- purposes. With the main gear in neutral, the shaft 54 can still be driven in either direction for pivoting the vehicle on itself. In a twinengined rail-vehicle drive, Fig. 2 (not shown), the stepped and simple planet trains are arranged on opposite sides of their corresponding driven pinions 39, 41. The Specification as open to inspection under Sect. 91 states also that the usual clutch and accelerator pedals may be eliminated. This subject-matter does not appear in the Specification as accepted.

Title: Device for indicating the expended life of a rotating machine
IPC: G07C3/10
Filed: 1975-06-18
Abstract: 1513428 Indicating engine life ROLLSROYCE Ltd 7 June 1976 [18 June 1975]  25879/75 Heading G1N (A) To indicate the expended life of a rotating machine by counting the cyclic variations in a relevant parameter, e.g. speed, a count is increased the first time a speed signal reaches a given threshold but the production of further counts at this threshold is inhibited until the speed signal has reached a second, e.g. lower, threshold. The detectors 1-21 are set to thresholds ranging from 10% to 105% of design speed. A signal output from one of the detectors 8-21 causes a bistable circuit 52 to deliver a count pulse to an OR gate 53 and to a bi-stable store 58. A monostable device 54 provides a reset pulse to bi-stable circuit 52 and an electro-mechanical or electronic indi-  cator 55 records a count of one. The store 58 inhibits further production of count pulses by circuit 52 until it is reset by a signal from a detector on line 60. The stores corresponding to detectors 13 to 21 are reset by signals from corresponding ones of detectors 5 to 12 and the stores corresponding to detectors 8 to 12 by corresponding ones of detectors 1 to 4. The reset signals are generated by the input signal to the detectors reducing below the respective thresholds. The variable characteristic of the generated input signal may be its frequency. A further count representative of temperature variation may be added to the speed cycle count.

[Also in Division B7] A railway vehicle has two relatively movable parts, one part 2 having rollers 5 movable up tracks 4 on the other part. The idlers 5 have a central portion 6 and a relatively movable ring 7 in engagement with a friction lining 8 on a block 9 fixed to part 2, the portion 6 carrying a pawl 10 spring biased into engagement with teeth 11 on ring 7. In one direction of rotation of rollers 5 the pawls cause rings 7 to rotate with the rollers which are thus retarded by lining 8 in accordance with the load on part 2 and in the other direction the rollers rotate relative to rings 7 and no retardation is produced. Several pawls may be provided in each roller, Fig. 15 (not shown). Alternatively, the part 2 may carry a shoe in association with each roller, which is controlled by a spring responsive to movement of the roller, so that the shoe is moved to act on the track only when the roller moves up the track. Hydraulic braking proportional to the load may also be provided.

Abstract: 1,242,771. Card/tape readers. WESTERN ELECTRIC CO. Inc. 22 May, 1969 [28 May, 1968], No. 26241/69. Heading G4M. [Also in Division H1] A punched card 15 is sensed by a row of members 70, each having a feeler portion 75 biased towards the card by a spring 88 and an actuating portion 74 containing a permanent magnet 78 for actuating a sealed reed switch 86 on sensing of a perforation. The feeler portion 75 includes a wheel 80, Fig. 4, the spindle of which is free to slide in a slot in the portion 75, whereby engagement of wheel 80 with the leading edge of a perforation pushes the wheel spindle to the bottom of the slot and engagement with the trailing edge of the perforation pushes the wheel spindle to the top of the slot, so that a longer dwell time in the perforation is obtained as the card moves past the feeler portion. The card is manually inserted in a slot 52 and its feed holes 18 engage a sprocket 32 to wind a spring 35. When a start bar 100 is pushed down a latch 108 is released so that the latch 108 trips a pawl 38 to allow the spring 35 to drive the card 15 upwards by means of sprocket 32. Correct positioning of the card is ensured by drums 28, 30 having rubber rings 34 and a spring side edge guide 60. Latch 108 biases the nose 94 of a control hole detector 92 against the card and a vane 90 is pivoted to allow the sensing members 70 to pivot their feeler portions 75 into engagement with the card. Sensing of the data perforations is effected as described above as the card is driven out until a control hole 17 causes pivoting of member 92, whereupon latch 108 is disengaged from a stop 95 and spring 102 moves the start bar 100 upwards to re-engage latch 108 and pawl 38 and stop the cards. Sensing may be continued on again depressing start bar 100. The card may be ejected at any time by depressing a bar 112. (For Figures see next page.)
