IPC: A41C1/00
Filed: 1917-06-04
Abstract: 112,889. Hume, E. F. June 4, 1917. Corsets are made of nine, more or less, specially shaped pieces for each half corset. These pieces, except the two back ones which are used for lacing and which are uniform in width throughout, are alternately wide at the top and narrow at the bottom, and narrow at the top and wide at the bottom. The sections for one half of a corset are shown arranged in order in Fig. 3, numbered 1 to 9, and the edges are joined together as shown from 11 to 18, 1 being the first or front section and 9 the last or back lacing section. The waist line is indicated at 10 in each section. The completed corset is shown in Fig. 1. The stiffeners in the front sections are each formed in two parts, a long top piece 20 and a short bottom piece 19, which are in alinement with one another, while the front busk 24 has its lower end 25 curved inwardly on a line approximately on the juncture of the two stiffeners 19, 20.

IPC: C14C1/08
Filed: 1927-03-24
Abstract: 281,919. Ehrenreich, A. Jan. 26, 1927, [Convention date]. Tanning with special chemicals; mixed tanning processes; currying and impregnating.-The skins of fish particularly of the shark type are treated after liming with colloids of the type of gum tragacanth or extracts of algae or of fenugreek, these having a tanning effect, produced apparently bv surrounding the skin fibres with a sort of insulating envelope. A mechanical treatment may follow with the object of disposing the fibres parallel to one another. Prior to the colloid treatment the skins may be disintegrated with enzymes, and subsequent thereto may be tanned by a known vegetable or mineral process, e.g. a chrome process. For producing waterproof leather the skins after colloid treatment are dried and impregnated with a waterproofing solution. such as a solution of rubber or stearate of lime. in benzole, after which they are curried.

Abstract: 635,675. Protective arrangements. FORGES ET ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT, and TEZNER, S. March 24, 1948, No. 8613. Convention date, March 26, 1947. [Class 38 (iv)] Lightning arresters for medium and high voltages comprising seriesconnected spark - gaps located alternately on opposite sides of the axis and voltage dependent resistances, have elements arranged in parallel connection with each of the spark-gaps which constitute both capacitances, whereby the voltage distribution over the gaps is maintained during normal lowfrequency conditions, and resistances, which in association with the capacitances to earth determine the distribution during highfrequency or steep wavefront conditions. These elements are constituted by sectors 18, 19 secured to metal plates carrying the gap electrodes 13, the sectors being of semi-conductive material having relatively, high resistances, such as a synthetic resin in which conductive material is dispersed. The metal plates are separated by insulating spacers 10 and the spark-gap electrodes, of which one of each pair is adjustable, have horn-like extensions and are each embraced by pole-piece loops 16 of magnetic material to produce a blow-out effect upon the arcs. Blocks of voltage-dependent resistance material 7, arranged below the gapseries, are centred by insulating blocks 8 and supported on a metal plate 4 closing the insulating container 1 and connected to a terminal member 5. A cover 2 carries the high-tension terminal. To determine the capacitances to earth of the gap elements, part of the container may be metallized.

Abstract: 241,511. Ribes, P. C. Oct. 15, 1924, [Convention date]. Steam-traps.-A steam trap of the type in which the water outlet valve is controlled by the expansion of a capsule containing volatile liquid, employs a mixture of water with organic compounds such as alcohols, ethers, and hydrocarbons in the capsule, the vapour pressure of such a mixture being greater, by substantially the same amount, than the vapour pressure of water at the same temperature. The capsule 6 is carried by a screw 8 secured in a ring 7 clamped between the parts 1, 3 of the casing. The volatile liquid is introduced through a passage in the screw 8, closed by a ball 10 which is secured by a screwed plug 11. The discharge valve. 13 has an annular groove 15 which assists the valve in opening quickly, and to its full extent. A suitable volatile liquid consists of water 50 parts, hexane 25 parts, benzene 25 parts. The diaphragm, 16, Fig. 2, is corrugated on both sides of a parabolic centre line 17, the corrugations becoming flatter at the outer end, and merging into curves 19, 20.

Abstract: 576,114. Switch contacts. ERSKINE, HEAP, & CO., Ltd., and ALLCOCK, W. May 9, 1944, No. 8799. [Class 38 (v)] A circuit breaker is arranged so that the contacts engage with aligned abutting surfaces, to give a large contact area when making circuit, but the contacts separate at the tips only, when breaking circuit. When making circuit, bar p presses insulated block q, on displacer a, upwards against spring b so that the levers g, carrying contacts k, are forced to close on bar p, as the rollers j ride along cam path f from recess d to recess e. The final movement of the bar p gives a cleaning action. When the circuit is being broken the displacer a swings the levers g outwards immediately the bar p clears contacts k, so increasing the breaking speed. The movable bar may be of rectangular or hexagonal section. When in the closed position the top and bottom portions of the bar p are clear of the top and bottom respectively of the con tacts, whereby normal engagement is betweer surfaces undamaged by arcing.

Abstract: 1360739 Winding webs OTARI ELECTRIC CO Ltd 25 Feb 1972 [1 April 1971] 8826/72 Heading B8R In an apparatus for winding recording tape 2 from a master reel 1 into a cassette 50 of the type having a loop of leader tape 54 with one end fastened to each cassette spindle, the leader 54 is supported on a fixed support 18 in mutual engagement with a leader support arm 12, and cut at 35. The arm 12 is then pivoted clockwise, one end of the severed leader being held on the fixed support 18 and the other on the arm 12, by suction. A recording tape support arm 13 holding an end of the recording tape 2 is then moved into engagement with the fixed support 18 and the leader and recording tapes spliced by a length of adhesive tape fed from a roll 40 held on a pivotable arm 39. A shaft 51 is then rotated to wind a predetermined length of recording tape on to a cassette spindle. The tape 2 is cut again at 35, arm 13 is moved away and arm 12 moved back to abut the severed end of tape 2 and the other end of the leader which are again spliced. The tape 2 on the master reel 1 may have programmes recorded thereon and spaced by blank lengths. In this case, the tape, which is fed via rollers 3, 9, 5, 11 and 55 over the fixed tape support 18 and the tape support arm 13, the latter initially assuming the illustrated position of the arm 12, is initially fed to a tape removal roller 53 on which the tape 2 is wound until a detector 8 senses a stop signal recorded on the tape. This feed path is tensioned by rollers 6a, 6b on a biased arm 6. The tape 2 is then cut at 35 and the arm 13 pivots to its illustrated position thereby moving the cut tape end to a vertically reciprocable gripper carriage 22 which feeds the tape between the pins 30, 31 of a store. The tape is then cut by a mechanism (59), Fig. 4d (not shown), in the vicinity of arm 13, this unrequired portion of blank tape being discarded. The splicing and winding operation for the recorded tape is then started. Alternatively, the recording tape may be blank and predetermined lengths, measured by a counter, are wound into individual cassettes. A reel motor 1<SP>1</SP> may apply tension to the tape 2.
