Title: Improvements relating to Variable Electrical Devices
Inventor: YOUNG STANLEY
IPC: H01C10/30
Filed: 1968-03-21
Abstract: 1,194,798. Variable resistors or inductors. FERRANTI Ltd. 20 March, 1969 [21 March, 1968], No. 13662/68. Headings HIS and H1T. The manufacture of a variable electrical device (e.g. potentiometer or inductor) having a wire-wound core 21 includes the step of applying pressure to the contact track by relative movement between a hardened roller 20 and the track both along the length and across the width of the track. The core is held in a chuck 13 which rotates; and the roller 20 is pressed against the track by a weight 19 fixed in any desired position on a loading arm 17. (Alternatively, a tension spring may be connected between the arm 17 and bedplate 10.) The roller is moved across the width of the track by raising a ball-race 18 on a lead screw 15. Alternatively, the arm 17 may be disposed horizontally and moved towards or away from the chuck by a similar lead-screw (Fig. 3, not shown). The screw 15 may be coupled to the motor which drives the chuck 13. These arrangements are suitable for contact tracks on the inner or outer surfaces of toroidal or cylindrical cores. For tracks on the edge of toroidal cores or on flat circular cores, the axis of rotation of the roller 20 must be perpendicular to that of the core 21, so the chuck 13 may be vertically disposed (Fig. 4, not shown). For arcuate tracks the chuck may reciprocate. For a straight core, the chuck may reciprocate in a straight line perpendicular to the length of the arm 17. The roller 20, which preferably presents a convex surface to the winding, may be cylindrical or of the same shape as the winding.

Title: Improvements in apparatus for separating minerals of differing densities
IPC: B03B5/36
Filed: 1953-05-18
Abstract: 753,480. Washing granular material. GOUMENT, V. O. Aug. 16, 1954 [May 18, 1953], No. 13787/53. Class 82(2). A method of washing mineral material comprises flowing the material in a stream of water or dense medium down a trough which has a gap with a drop in level, the lighter material with most of the liquid jumping the gap and the heavier material falling out of the flow through the gap. As shown, applied to the washing of coal, the raw coal is supplied, with medium down a shoot 2 or the medium may be supplied as a jet at 4, to a trough 1 which may be smooth, or have transverse bars, or have a conveyer belt 31 with transverse bars 34 running along its bottom. A gap 8 is formed at the end of the trough 1 and a further trough 7, having an end piece 9 to adjust the width of the gap, continues at a lower level than the trough 1. Heavy particles fall out of the stream at the gap and are collected in a receptacle 16. The coal moves along the trough 7, which may be in the form of a sieve, and is discharged substantially free from water at the end thereof. The water may be recycled after the removal of fine coal and slurry in a settling tank 23. Specification 717,449 is referred to.

Title: Improvements in or relating to the seaming of thermo-plastic sheet material
IPC: B29C65/10
Filed: 1953-05-18
Abstract: 760,920. Producing bias binding; seaming. BROUNCKER, C. F. Aug. 17, 1954 [May 18, 1953], No. 13915/53. Class 42 (1). The edges of nylon or other thermoplastic woven or non-woven sheet material are continuously joined by fusion (i.e. melting) produced by the application of heat to the edges of superimposed lengths of material while in motion. Bias binding is produced from woven thermoplastic fabric by cutting wide fabric into sections at an angle of 45 degrees, reversing alternate sections and seaming their selvedges together by the above method to produce a continuous length of material with the weave on the cross. The cross-seamed material is then cut into strips and edge-folded in the usual way. In the apparatus shown, two superimposed sections of fabric, with selvedges in register, are fed from a table I between a drum E and a narrow metal band A, which runs flush with the edge of the drum, so that the selvedges project slightly beyond the band and drum. A rotary cutter K spaced slightly from the drum edge trims off the selvedges and a gas burner or electric heater D fuses the projecting fabric edges together. Band A and drum E are driven at the same surface speed by a common chain N. The shafts of the band pulleys F, G are slightly out of parallelism so that the band tends to creep towards the edge of drum E, but is kept flush therewith by an edge roller B.

Title: Speed controlling and recording device for mechanically propelled vehicles
IPC: G01P1/11
Filed: 1932-02-04
Abstract: 380,148. Speedometers. HARROP, J. A., 68, St. Oswald's Road, Lupset, near Wakefield, and ROBINSON, M. W., 20, Berners Street, Wakefield, Yorkshire. Feb. 4, 1932, No. 13981/31. [Class 106 (iii).] Maximum speed controlling means with means for recording its use applied to speedometer for use on mechanically propelled vehicles comprises means for discontinuing or retarding the supply of fuel, gas or other motive power producing means when the vehicle reaches a predetermined speed, means for giving a signal just before this speed is reached, and means for recording the predetermined speeds and the duration of their control. The predetermined speed is shown by the pointer F1 set by a handle A through a shaft B and sleeve C, the arm D being positioned at the same time. The speedometer mechanism actuates a shaft E, arm H and pointer F2. Just before the predetermined speed is attained a terminal 1 on the arm H makes contact across the terminals 2, 4 on the arm D to show a coloured light or other signal. On the attainment of the predetermined speed the terminal 1 makes contact across the terminals 3, 4 to cut off or retard the supply of fuel, gas or other motive power producing means. The connections are made through the ring J and metal rings 5, 6, 7. The handle A moves the recorder K by the nut L on the screwed portion of shaft B. The nut is prevented from rotating by the straight portion M passing through the slot N. The recording ribbon T passes from spool P through slot Q and under recorder and through slot R to spool S which is turned by the mileage mechanism of the speedometer. The ribbon as it is recorded passes directly under an aperture or window to facilitate reading of recorded speeds. This aperture or window is made so that in case of dispute the recording ribbon can be signed by a witness or official.

Title: Improvements in combined hydraulic-mechanical power transmission systems
IPC: F16D33/18
Filed: 1952-06-03
Abstract: 722,287. Clutches. VOITH, GES., J. M. June 3, 1952 [June 6, 1951], No. 13987/52. Class 80 (2) [Also in Group XXIX] A combined hydraulic-mechanical power transmission device comprises at least a primary bladed wheel and a secondary bladed wheel, and uses a working fluid consisting of a mixture of a liquid and solid particles (e.g. small shot, turning swarf, metal powder &c.) of greater specific gravity than that of the liquid. As shown, a driving shaft 1 carries an impeller 2 to which is secured a casing 5 surrounding a turbine 3 on a driven shaft 4, a sealing ring 6 and rubber diaphragm 20 being provided and allowing the driving and driven members to move universally with respect to each other. The working fluid comprises a mixture of liquid and solid particles, and an internal chamber 7 is provided between the impeller and turbine. At take-up of drive, when the degree of slip between the parts is considerable, the flow of working fluid projects the solid particles into the chamber 7 and the device performs as a fluid coupling. As slip between the two parts begins to decrease, centrifugal force throws the solid particles outwardly and the coupling eventually transmits torque without slip. In a modification, Fig. 2 (not shown), the chamber 7 is provided in the hub of the turbine, and axial grooves along the internal periphery of the casing 5 increase the frictional grip of the particles therewith.

Abstract: 378,881. Cranes ; dynamometers. SMITH & SONS (RODLEY), Ltd., T., SMITH, F. H., SMITH, W. T., and SMITH, G. E., Steam & Electric Crane Works, Rodley, near Leeds. May 12, 1931, Nos. 13985 and 24834. [Class 78 (iv).] A fluid-pressure cylinder and plunger is arranged to form an extensible link or anchorage for the luffing-rope or the jib-tie, so that fluid is displaced and operates indicating or signal devices when the safe load is reached or exceeded. As shown in Figs. 1 and 6, the luffing-rope 6 is connected at 27 to the oil cylinder 10, and the piston 28 in the cylinder is connected by links 12 to the base 1. When the crane is under load oil is displaced into an auxiliary cylinder 13 against the resistance of a plunger 21 loaded by an adjustable spring 15, and this plunger is arranged to actuate indicator mechanism and to operate an electric bell or signal lamp, steam whistle or other alarm. The cylinder 13 is made as a detachable unit to be used with main cylinders 10 of different effective diameters according to the maximum safe loading of the crane. The spring 15 may be adjusted by a collar 24 and nut 25 on the auxiliary piston-rod 14. A bar 16 carried at the upper end of the piston-rod 14 operates a switch controlling an electric bell or warning lamp when the displacement of the plunger reaches that corresponding to safe loading. In a modification, Fig. 4, a fluid-pressure gauge 30 is connected directly with the main cylinder 10 and the pointer closes a bell circuit through a contact 32 on the dial. The dial, or the contact 32, may be adjustable. As shown, the dial is moved to bring the contact 32 nearer to the pointer when the jib comes to a small radius, by means of links 33 operated by a spring-pressed plunger 34 engaged by the jib. According to the second Provisional Specification the dial, pointer, and associated contacts may be enclosed in a transparent cover which is sealed to prevent tampering. Specification 376,282 is referred to.
