Title: Improvements in and relating to transformers
IPC: H01F38/08
Filed: 1926-09-13
Abstract: 258,287. British Thomson-Houston Co., Ltd., (Assignees of Chadwick, R. H.). Sept. 11, 1925, [Convention date]. Transformers.-The necessary magnetic leakage in high reactance transformers such as those used for bells, toys, high voltage testing apparatus, and ignition systems for vapour burners, is obtained by a core construction in which a centre leg 17 carrying the windings 10, 11 and disposed within an outer yoke member 13, is provided with laterally extending members 18 between the windings to form a shunt path for the flux. Small air gaps 20, Fig. 2, which may in some cases be four thousandths of an inch in length, are provided in the shunt path. The laminations of the inner core are frictionally retained in position between notches 15 in the yoke member, and in order to ensure an accurate fit, the laminations of the inner member may be punched from the same positions in the laminations of the yoke member that they are to occupy when assembled, a small projection 19 being formed on the inner laminations to prevent reversal in assembly.

Title: Improvements in or relating to plug-and-socket connectors for electrical circuits
IPC: H01R13/453
Filed: 1934-08-02
Abstract: 439,841. Plug couplings. LUNDBERG & SONS, Ltd., A. P., and PEGG, G., 477, Liverpool Road, Holloway, London. Aug. 2, 1934, No. 22554. [Class 38 (i)] A plug coupling having two live contacts and an earthing contact is provided with a shutter that covers the sockets and is moved aside to expose the live sockets by the action of a normal earthing-pin on a bevel formed on the shutter. In one form the shutter 27 turns on a pivot 28, being biassed by a spring 29 to a position to cover the live sockets 17<b>, 17<c> and the earthing- socket 17, the part covering the earthing-socket being bevelled where the pressure of the earthing-pin is applied. The spring may be of leaf or other form bearing on a pin on the shutter. The socket contacts carry terminals 13 and are loosely housed in discs 14, 18, between which is a retaining collar 16 on the contacts, and extensions 19 on the disc 18 surround the sockets. In a modification, a sliding shutter is employed having a spring at each side of a central earthing-socket over which the shutter is bevelled to effect the sliding movement against the springs. The sockets are so disposed that the plug cannot be wrongly inserted with one pin outside the fitting.

Title: Positioning systems
IPC: G05B19/40
Filed: 1967-05-16
Abstract: 1,126,648. Positioning movable members. INTERNATIONAL BUSINESS MACHINES CORP. 16 May, 1967 [11 July, 1966], No. 22565/67. Heading G4H. [Also in Division H2] A stepper motor 20 drives a recording head to any one of sixteen positions across the surface of a magnetic recording medium, the desired position address being stored in digital form in register 10. The actual position of the motor is indicated by reversible counter 16, the output of binary stages 1, 2, providing pulses to driving- circuit 18 for adjusting the position of the motor. A circuit 12 compares signals representing the actual and desired positions of the motor respectively to determine the direction of movement, and generates a series of pulses so that the motor is slewed through four steps when the numerical difference between the signals from the counter 16 and the register 10 exceeds four. The circuit 12 also generates a " no match" signal when the actual position and desired position addresses do not match. The outputs of the circuit 12 are fed to pulse generator 14 which provides motor step pulses and damping signals to the counter 16. If, after the end of four steps, the difference between the two addresses is greater than four, the four-step slew operation is repeated. If, however, the difference is less than four, the system reverts to a single-step mode until the " no match " signal is removed. When the recording head is to be moved from the zero position to the position address designated 6, for example, the position register 10 is loaded with the binary representation of the decimal digit 6 and the no-match and slew-compare lines becomes positive. The trigger 30 causes the inhibit-increment line to fall. The output of AND circuit 34 energizes single-shot 1, which through OR circuit 36, generates a motor step pulse forming the first of a set of four pulses which are timed by the single shots 1-6, whereby the motor moves through four increments without oscillation. At the end of the four-step slew, the location register contents steps up to four, the slew-compare line dropping when the difference between the two registers became less than four. The slew-damp single shot output passes through an OR circuit so that a sample signal resets the trigger 30, the output from AND circuit 34 firing the single shot 1. No output occurs from the AND circuit 33, the system reverting to the increment mode of operation which is similar to that described. in Specification 1,048,065.

Abstract: 1,176,972. Dehydrogenating alkyl aromatic compounds. UNIVERSAL OIL PRODUCTS CO. 16 May, 1967 [23 May, 1966], No. 22640/67. Heading C5E. A process for dehydrogenating an alkyl aromatic hydrocarbon having at least two carbon atoms in the alkyl group comprises mixing with the hydrocarbon feed, steam and a monomethyl-substituted aromatic hydrocarbon, contacting the mixture with a dehydrogenation catalyst at dehydrogenating conditions and separating and recovering the monomethyl substituted aromatic hydrocarbon and the resulting alkenyl aromatic hydrocarbon product from the reaction zone effluent. The alkyl aromatic hydrocarbon may be heated to less than 500 C., the steam and methyl aromatic hydrocarbon may be mixed and heated separately from the alkyl aromatic hydrocarbon to less than 500 C., and the pre-heated streams combined and heated to 566-704 C. and charged to the dehydrogenation zone. A preferred embodiment is a two-stage dehydrogenation process in which the mono-methyl substituted aromatic hydrocarbon preheated to 566- 704 C. is employed only in the second reaction zone. Examples describe the dehydrogenation of ethylbenzene to styrene in the presence of toluene using an iron oxide catalyst.

Abstract: 496,153. Controlling aircraft. TAMPIER, R. Aug. 28, 1937, No. 23605. [Class 4] [Also in Group XXIV] In an assemblage of control levers, particularly for aircraft, means are provided for axially compressing the assemblage for regulating the sensitivity of the levers, and further means to increase the compression sufficiently to lock said levers in any position. The assembly comprises an upper set of four levers, viz. two similar throttle control levers 1 and two similar carburettor mixture control levers 2, all being provided with hubs 3 journalled on a shaft 2 supported in bearing members 5<1>, 52 in side plates 6, 6<1>. Also on shaft 4 are hub portions 7 of sector shaped members 8 prevented from rotating by rods 9. Projections 10 on plunger portions 11 coact with stops on the flanges of the members 8. The construction of the levers and stops is described in Specification 464,686, [Group XXIV]. The bearing member 5<1> is rigidly clamped between the plate 6 and sector 8 by a nut and bolt 14 and by a nut on a rod which passes through apertures in a plate 17 between the hubs 3 of levers 1. The bearing member 5<2> has slight axial movement, but is prevented from rotating by projecting members 18 engaging holes in the side plate 6<1>. The shaft 4 is secured at one end by a nut 19, the other end passing freely through the member 5<2> and being threaded to receive a threaded hand wheel 20. An exteriorly-threaded sleeve 22 is slidable on shaft 4, engages the member 5<2> and is prevented from rotating by a pin 23 engaging a notch in a flange of the sleeve. Threaded on the sleeve is a flanged nut 25 to which is secured a lever 26. The flange has an arcuate portion engaging a pin 28 to limit the movement of lever 26 to about 90‹. The degree of sensitivity is varied by turning the wheel 20 and so varying the frictional resistance. The thread on sleeve 22 being of coarser pitch, movement of lever 26 produces sufficient axial movement to lock the levers. Projections 29, 30 ensure that each lever is never advanced more than a given angle relatively to an adjacent lever. Four additional control levers 32 are carried on a second shaft 31 having bosses 33, and the degree of sensitivity is adjusted by nuts 37. The bosses of all the levers carry short ball-ended levers 38 to which the transmission rods &c. are attached.

Abstract: 647,449. Endless-belt conveyers. DAILY MIRROR NEWSPAPERS, Ltd., GIBSON, W., and HIGGS, R. A. Sept. 8, 1948, No. 23606. [Class 78 (i)] Cylindrical bodies are discharged from an endless belt by means of their own momentum by providing an arm which is struck by the body and adapted to transmit the motion to means exerting a thrust on the side of the body causing it to roll off the belt. A roll of newsprint A is conveyed by an endless belt 1 having a concave upper surface. An arm 8 provided with a roller 9 is pivoted at 10 to a bracket 11 on a lever 13 which is also pivoted to a carriage 5 by means of a shaft 12. Arm 8 normally rests against a stop on the bracket 11 but can be lifted out of the path of body A when desired about the pivot 10. When in position, however, the roll A transmits a movement via the arm A to lever 13, which transmits a parallel motion to a bar 14 disposed parallel to belt 1, by utilizing a link 15 pivoted to carriage 5 and bar 14 so that it is parallel to lever 13. Bar 14 through rollers 17 mounted on it pushes the roll sideways off the conveyer, Fig. 2. Carriage 5 travels along the side of the belt 1 on rollers 6 and is guided in a slot 4 in which a roller 7 is located. Carriage 5 may be transferred to a similar slot 4 on the opposite side for changing the side of delivery and is locked in the desired position.
