Title: Improvements in electric remote control apparatus
IPC: H02J13/00
Filed: 1931-05-14
Abstract: 369,462. Electric clocks. LANDIS ET GYR, SOC. ANON., 1, Hofstrasse, Zug, Switzerland. May 14, 1931, No. 14242. Convention date, May 17, 1930. [Class 139.] In a device for the remote control of operations such as the regulation of clocks, in which circuits of different frequency are employed to actuate resonance springs, each spring drives a mechanism which is brought out of engagement with a driving wheel mounted on a control shaft when the wheel reaches a predetermined position, other driving wheels being then in positions suitable for operation through their respective associated resonance springs. In the construction shown, in which the invention is applied to rate changing in electric tariff meters, three discs 3, 3<1>, 3<11>, adapted to be actuated, respectively, by resonance springs 1, 1<1>, 111, are secured to gear wheels and are loosely mounted on a shaft 4. Each wheel, such as 2, engages a wheel, such as 6, which is formed with a gap 5, and is fixed to a shaft 9. This carries a contact disc 12 provided with insulating material 11 on part of its periphery, which is adapted to be engaged by contact springs 13, 14, a third spring 15 engaging a nut 18. The springs 13, 14 are connected in circuit, respectively, with relay change-over coils 16, 17 of a triple tariff electric meter, the coils being connected to one line 19 of a source of power, the other line 18 of which is connected to the spring 15. When the spring 1 is set in vibration by its controlling frequency the disc 3 acts to drive the wheel 6 and hence the disc 12 during which time coil 17 is energized. When the gap 5 in the wheel 6 arrives within the range of the wheel 2, the wheels 2 and 6 are disengaged and the shaft 9 comes to rest, the spring 14 by this time engaging the insulating material 11 and the spring 13 engaging the conducting portion of the rim of the disc 12. The circuit of coil 17 is thus opened and the circuit of coil 16 closed whereby the meter is changed over from one tariff to another. In a similar manner the operation of resonance spring 1<1> results in neither of the coils 16, 17 being energized and the operation of resonance spring 1<11> causes the energization of coil 17, with consequent selection of the meter tariff.

Abstract: 645,839. Automatic speed - control systems; running alternators in parallel. BRITISH THOMSON - HOUSTON CO., Ltd. May 29, 1947, No. 14324. Convention date, May 29, 1946. [Class 38 (iv)] A regulating system for a dynamo - electric machine comprises a variable speed ratio transmission device between a prime mover and the machine, the device being controlled by a multiple coil solenoid hydraulic valve mechanism, one coil being connected to speedresponsive apparatus, and a second coil being connected to means responsive to the electric load. The arrangement is applicable to a system in which a number of alternators are connected in parallel, each being driven by a variable-speed prime mover such as an aircraft engine. In the Figure, an aircraft engine 1 drives an electric generator 3 through a variable-speed ratio device 2. The output from a tachometer 5 which is also driven from device 2, is used to provide a current in coil 9 proportional to the speed of the generator 3. A further control circuit responsive to the power output of the generator is provided by means of transformer 11, having an output proportional to the 'output voltage of the generator, and resistance 17 which carries a current proportional to the current supplied by the generator. The current vector is added to or subtracted from the voltage vector appearing across the primaries of transformers 12 and 13, so that a current proportional to in-phase power component is produced in coil 18. This arrangement enables a slight droop to be given to the generator load characteristic to facilitate the connection of such generators in parallel. The currents through coils 9 and 18 control the operation of a hydraulic pilot valve 27 which controls oil pressure to operate a servomechanism 34. Mechanism 34 controls the speed-ratio device 2, the arrangement being such that the first speed responsive means acts to maintain constant generator speed, and the second means, responsive to the load, modifies this speed characteristic. Under steady, noload conditions, the force due to current through coil 9 is just balanced by that due to spring 31. A centrifugally-operated switch 35 which operates on severe overspeed of the prime mover, is provided, which when operated forces the pilot valve 27 down to the limit of its movement by means of coil 38, so that latch member 39 operates to lock the mechanism in the reduced speed position until re-set manually by the operator. An over-running clutch 2<SP>1</SP> is also provided to assist in maintaining synchronism during rapid deceleration of the aircraft engine.

Title: Improvements in magnetic and electro-magnetic clutches, brakes and the like
IPC: H02K49/06
Filed: 1942-10-13
Abstract: 561,023. Dynamo electric machines. BRAHAM, G. W. Oct. 13, 1942, No. 14365. [Class 35] [Also in Groups XXIV and XXXIV] Driving and driven shafts g, f are coupled by clutch members e, d, attached to the shafts and having adjacent end faces t, s, which are moved into contact to transmit torque by a stationary electromagnet surrounding the members and comprising a. yoke a and polepieces b, b<SP>1</SP>, enclosing an energizing coil r. The magnet is supported from the shafts by brackets k, h. The member d is splined to the shaft f to allow that member to move axially into contact with the member e when the coil r is energized. A spring p, which may be enclosed by a cap n enclosing lubricant for the splined connection, maintains the clutch members out of contact when the coil r is de-energized. The clutch member d rotates as a unit with the member e when the coil is energized and the torque resisting rotation of the shaft f is not greater than can be transmitted by.the magnetic forces causing the two members to adhere, but when the torque exceeds that value, slipping occurs and current circulates from one end face to the other due to the difference in speeds of the two members in the magnetic flux. This current produces on the member d an additional torque assisting rotation of the shaft f due to a motoring action. Good conducting material such as. copper may be applied to the end faces of the clutch members to increase the current which flows during slipping, and graphite or other lubricant may be contained in pockets in the end faces to prevent abrasion of these faces during slipping. The torque necessary to cause the clutch members to slip may be varied by providing variable excitation of the coil r, and in cases where constant torque is to be transmitted, a permanent magnet may be utilized instead of the electromagnet. The device may be used as a brake by the provision of means for temporarily constraining one member against rotation so that the second member is restrained by the action of the adhesive and electromagnetic forces. In a modified construction, the clutch surfaces are formed between the polepiece b<SP>1</SP> and yoke a of the electromagnet and the driving and driven shafts are arranged coaxially, the driven shaft carrying a support w, for the unitary parts a, b of the magnet which rotate with the shaft. The coil r is stationary and surrounds a central stationary iron core through which the shaft g passes. The bracket k supporting the polepiece b<SP>1</SP> is rigidly secured to the shaft g.

Abstract: 378,863. Crates &c. NICKLIN, J. B., Lindencroft, Ashton-under- Hill, near Evesham, Worcestershire. May 16, 1931, No. 14526. [Class 18.] A crate &c. in which the separate members are formed of slats mounted on battens is assembled so that the ends 3 of the base slats project from inside the crate into gaps formed between the slats of the ends and rest on the lower slats 13 bordering the gaps, and the base also engages with the lower edges of the sides. The battens 6 of the sides and/or the slats thereof rest upon the projecting ends of the base battens 1, these latter battens also abutting against the slats 13 which are narrower than the other slats of the ends. Due to the construction, the bottom edges of the ends are situated lower than the bottom edges of the sides, and the base is raised off the floor. In assembling the crate the ends are first placed up against the battens 6 and nails or screws carried by the sides or the battens 11 of the ends are driven home and riveted over ; the base is then inserted and the remaining side fixed. Lateral movement of the base is prevented as the outer slats thereof abut the inside edge of the end battens. According to the Provisional Specification, the slat 13 is a relatively stout strip.

Filed: 1961-04-24
Abstract: 997,701. Mini car pushers. D. G. SHAW. July 9, 1962 [April 24, 1961], No. 14676/61. Heading B7L. Ram means for pushing mine cars or the like is characterized by a trolley 1 adapted to have travelling movement in positive dogged engagement with a mechanical creeper 5 and further adapted to abut mine cars in order to push them along. The trolley 1 has dog members 3 formed on its underside for engagement with dogs 4 on the creeper 5, and the trolley is guided at each side by guide rails 6, rollers 14 on the trolley preventing it from lifting out of engagement with the creeper 5. The trolley also has an upwardly extending pusher member 11 for engagement with dummy axles 12 on mine cars. The pusher member 11 is pivotally mounted on the trolley and is urged by a spring 13 to the position shown where it is held by a stop 18, Fig. 7, this arrangement enabling mine cars to depress and thus pass over the pusher member. The trolley also has two pivotally mounted catches 16, 16a, Fig. 1, which are able to pivot only from their normal vertical position clockwise and anticlockwise respectively as viewedin Fig. 1. When the trolley reaches the end of its run, as in Fig. 1, it is stopped by a resilient buffer 20 and the dogs 3 are then out of engagement with the creeper 5, the catch 16 pivoting to allow continued movement of the creeper. If the drive to the creeper 5 is reversed then the catch 16 will engage with the dogs 4 and the trolley will be driven along the guide rails 6. A similarly positioned buffer 22 is placed to stop the trolley at the other end of its run, and the catch 16a will then act in the manner of the catch 16 as described. Alternatively, spring- loaded catches 26, 26a, Fig. 7, may be used, and the trolley may be made to actuate a switch at each end of its run to stop or reverse the drive to the creeper 5. The trolley 1 may be articulated to intermediate trolleys, the leading one of which will then carry the pusher member 11 (Fig. 4, not shown), and the intermediate trolleys need not engage with the creeper 5.

Abstract: 810,199. Knitting. PARTHUM, A. R. May 23, 1955 [June 1, 1954], No. 14796/55. Class 74 (2). A fully fashioned stocking blank having a reinforced foot has warp threads knitted with the ground yarn along the inner edge of the foot reinforcement to provide a barrier against ladders commencing in the reinforced area of the foot. At least three warp threads are knitted in a series of at least three adjacent wales or groups of wales at the inner edge of each reinforced area in each course of a number of courses, and in a subsequent course the warp guides are shogged so that the warp threads are knitted in a further series wales offset from the first series in a further number of courses. The shogging of the warp guides is such that at least one wale in the second series is coincident with a wale in the first series and this wale or wales will contain in the course in which shogging occurs a warp loop or loops composed of two or more warp threads. Fig. 8 depicts the structure of the warp stitches where each needle of a series is normally fed by a single warp yarn and Fig. 9 depicts the structure where two needles of a series are normally fed by a single warp yarn. The warp yarn guides may be of tubular formation secured in a holder or may comprise arms pivoted in the holder and having eyes for the passage of the yarns in the lower ends of the arms.
