Filed: 1974-08-22
Abstract: 1483934 Golf training apparatus OT SPEDDING 22 Aug 1974 [31 Aug 1973] 37015/74 Heading A6D Apparatus for training golfers comprises a retaining structure comprising a rectangular frame (preferably manufactured from a length of aluminium), and two foot rests 7, 8 held by the retaining structure in spaced apart arrangement, each footrest having a foot supporting surface 11, 12; the footrest 7 is located in the frame by means of spigots 20, 24 and holes 3 in the walls 1, 2 of the frame and can rock about the axis thus formed between limits defined by the abutment of flanges 14, 15 with a longitudinal frame member 4. The footrest 8 may be rigidly mounted in the frame as shown or may be mounted for rocking as is footrest 7. A foldable leg-rest 21 is provided which when in use is substantially over footrest 8. In use the golfer stands with his forward foot on the footrest 7 and his back foot on footrest 8; during his back swing the leg rest 21 prevents backward sway of the 'body and during his down swing the rocking of the footrest 7 aids in the transference of weight from the back foot to the forward foot.

A rail-mounted terminal unit comprises a pair of terminals connected by a conductor which carries a sliding member which can be clamped on to the conductor by a screw, the whole assembly being mounted in an insulating casing. The conductor can be made in two halves 1a and 1b, the sliding member movable on 1a, and its head engaging a forked section at the end of conductor 1b, so that if screw 3 is loosened the member 2 can be moved to break the contact between terminals, x and y. A plurality of these units can be mounted in adjacent positions on the rail R, and adjacent units can be interconnected by a conducting comb-like member which is located between screw 3 and the forked end of conductor 1b, passes through a hole in the insulating wall and is connected in a similar manner to the next unit. In a second embodiment the conductors 1a and 1b can be formed as one, and then movement of the slidable member 2 serves only to make and break contact between adjacent members through the comb-like member. Sockets can be incorporated in the assembly for testing jacks, Fig. 3 (not shown).

Abstract: 326,882. Anglo Pencil Co., Ltd., and Smith, M. Dec. 24, 1928. Transfers; transferring designs. - Pencils and the like are ornamented by the application thereto of a transfer having a backing of aluminium &c. other metal foil and securing the adherence of the transfer by the use of a fixing-medium which acts as a solvent for the varnish coating of the pencils &c. The transfers are printed in transverse spaced relation on a strip of gummed paper and are backed with metal foil, and, on application to the pencil &c., the foil underlies the transferred design. The transfer is supported, paper downwards, on a water-absorbent surface, the fixing-medium is supplied, and the pencil &c. is rolled, either manually or automatically, over the transfer. The supporting-device may consist of a hinged spring-raised plate having a leather surface covered with chamois leather or similar water-absorbent material. Alternatively, a rotatable drum 9, having a surface of chamois leather or like material, is employed. The drum dips into an adjustable water container 11, and excess water is removed by rollers 12 or the like. The strip 1 bearing the transfer is fed to the drum and fixing-solution is applied by rollers 15 from a container 14, the pencils &c. being then rolled on the transfers. The fixing-solution may consist of a solution of bleached lac in methylated spirit; for use with cellulose acetate varnish, a solution of gelatine containing sodium lactate or other high boiling-point solvent of cellulose ester, or a solution of gelatine in nitric acid may be employed; or with shellac varnishes, a strongly alkaline solution of gelatine may be used. After application of the transfers, the pencils &c. are coated with nitrocellulose or other transparent varnish.

Abstract: 1,043,747. Automatic frequency control systems; telegraphy. GENERAL ELECTRICAL CO. Ltd. Dec. 11, 1964 [Sept. 30, 1963], No. 38503/63. Headings H3A and H4P. In a frequency-shift telegraphy system the frequency Fx of the output oscillator 1 is stabilized by mixing with one of a plurality of crystal-controlled harmonic frequencies Fo to produce a lower (difference) frequency (Fo-Fx) which is applied to a phase discriminator 7 together with a selected one of a plurality of crystal-controlled low-frequency oscillations Fa, Fb, and the discriminator output applied as feedback through a low-pass filter 11 to a reactance valve circuit 2 stabilizing the oscillator 1. Frequency shift of the output of oscillator 1 is effected by an electronic switch 8 which connects oscillator 9 or 10 to the phase detector. The low-pass filter is given a narrow pass-band to prevent high-frequency transients affecting the output oscillator frequency on switching.

Abstract: 369,293. Twisting-apparatus for imparting more than one twist per revolution. BRITISH CELANESE, Ltd., 22, Hanover Square, London, and POOL, W., of British Celanese, Spondon, near Derby. Dec. 24, 1930, No. 38864. [Class 120 (ii).] In a twisting-device of the kind wherein yarn is drawn into a loop from a package and is rotated therearound, an annular race 21 is provided on the package support 6 and is engaged by one friction wheel 18 of a pair on a pin 20 rotating with the driven spindle 9, the other friction wheel 19 engaging with another race 22. If the wheels 18, 19 are of the same diameter and the race 22 is maintained stationary, the package holder is maintained stationary and two twists are imparted to the yarn for each revolution; variation in the degree of twist may be effected by varying the sizes of the friction wheels and races or by rotating the race 22. The friction wheels are freely mounted on the pin 20, or the pin is freely mounted so that contact of the wheels and races is ensured by the action of centrifugal force. The races are enclosed by a flange 24 of an enlarged part of the spindle which also carries a guard 27 to prevent licking and to prevent the fouling of the yarn with lubricant. A guide disc 30 for the yarn is mounted on ball bearings on a tube 32 secured by springs 33 in the bore of the bobbin, or may be fixed on the tube 32.

Patent GB-347241-A (GB)
IPC: D01D10/04
Filed: 1929-12-20
Abstract: <PICT:0347241/IV/1> <PICT:0347241/IV/2> Artificial filaments in the form of cakes, produced by the centrifugal or pot spinning method, or in the form of bobbins produced by the bobbin or parallel method are used in a warping frame for the production of warps, or in a knitting machine or loom for direct conversion into fabric.  The filaments are washed, after-treated, softened or sized, and dried in the manner described in Specification 311,391 which obviates the step of skeining or hanking.  For centrifugally spun filament, a carrier or sleeve d, which is preferably flexible, is inserted in the cake so that it projects from each end and enables the cake to be used directly for knitting or weaving.  The sleeve d may, as shown, be inserted in the perforated sleeve b used in the production of cakes according to the method described in Specification 311,391, [Class 2 (ii), Cellulose &c.], or may be inserted in the cake after the sleeve b is removed, and serves also as a protection for the ends of edges of the cake when strung on a rod for drying, and may be used during rewinding in accordance with the method described in the prior Specification.  A support for the cake in circular looms, stocking-knitting machines, warping frames or shuttleless looms comprises a wooden disc e with a soft washer g of felt or hide which prevents entanglement of the filament with the base of the cake if unwinding is interrupted, and contact of the filament with the upper end of the tube during unwinding prevented by a smooth or polished tray h.  The disc and washer facilitate transport; additionally for this purpose a similar disc and washer k, l may be placed on the top of the cake as shown in Fig. 4, and the whole packed in a box m.  For untwisted or "slack" filaments produced by the bobbin method, large perforated bobbins, for example of 120 mm. diameter and 200 mm. length, are used which, after treatment of the material thereon, as described in Specification 311,391, are mounted on supports similar to the supports e in, for example, a shuttleless loom. This non-twisted yarn may be passed through a solution, such as glue, gelatine or oil emulsion, which serves to hold the filaments together in their passage from their support while being formed into fabric.
