Title: Improvements in and relating to sliding clasp fasteners
IPC: A44B19/48
Filed: 1939-02-17
Abstract: 525,346. Sliding-clasp fastenings. PUSCHNER, J., and PUSCHNER, J. Feb. 17, 1939, No. 5425. Convention date, Feb. 17, 1938. [Class 44] In the manufacture of sliding-clasp fasteners wherein a loose mass of fastener elements are tumbled in a sorting drum 4 and delivered therefrom in proper orientation, these sorted elements 8 pass to a horizontal stacking channel 16 formed between a fixed ring 14 and the rim of a rotary disc 12, the elements hanging on such rim by their interlocking projection 9 and being in contact with one another. A gap is provided in the fixed ring but is closed by a spring 21 and located just beyond is a stop. A plunger 22 depresses the end element downwardly and outwardly against the pressure of the spring 21 so that it straddles the tape 23 on to which it is then fixed by cam-operated clamping jaws 31. The tape 23 is intermittently moved forward by ratchetdriven feed rollers 24. Due to the legs of the elements being inclined excess feed to the stacking channel 16 results in excess elements moving upwardly out of the channel by a wedge action and falling into a container. A cover plate 32 is provided to prevent such rising of the elements at the region where the fixing on the tape is effected.

Title: Dynamic balancing system for rotating structures
IPC: F16C32/06
Filed: 1962-02-13
Abstract: 951,704. Bearings; balancing shafts. S.E.E.P.F. Feb. 13, 1962 [Feb. 28, 1961], No. 5448/62. Headings F2A and F2U. In a fluid bearing, the shaft is concentrically maintained by a balancing device integral therewith. In an embodiment, the shaft 2 is mounted in a sleeve 3 and pressurized fluid is supplied to an inlet 41 in the sleeve and into a manifold 42 thereof, from where it passes into radial passages 43 and an axial bore 44 in the shaft. The axial bore 44 of the shaft 2 supplies fluid to equispaced annular chambers 21-23 therein by means of radial passages 46, longitudinal passages 26 and radial passages 27, and the fluid is returned to a sump via grooves 31-33 and channels 37, 38. The balancing device 4 has an annular member 1 supported by walls 5, 6 which are held to the shaft by a shoulder 8 thereof and by a nut 9 threaded thereon. A spacer-ring 7 is positioned between said walls 5, 6 and a continuous annular space so formed is separated into chambers 17-19 by rollers 11-13, the arcuate displacements of which are limited by stops 51-53 on the ring 7. Pressurized fluid is supplied to each chamber 17, 18 or 19 through radial passages 25 which connect to the longitudinal passages 26. In use, an offset weight such as " B " has its centrifugal force compensated by the rollers 12, 13 being re-positioned nearer to the roller 11. This is effected by an increase in pressure in the annular chamber 21 which produces a corresponding increase of pressure in the chamber 17, the pressures in the annular chambers 22, 23 and in the chambers 18, 19 being subsequently decreased. When the pressures in the annular chambers 21-23, and hence in the chambers 17-19, are equalised, the rollers 12 and 13 remain stationary in their displaced positions. The rollers 11-13 may have axial bores therein to facilitate their arcuate displacement and restrictors 30, 47 may be provided in the radial passage 25 and in the longitudinal passage 26 respectively.

Abstract: 873,472. Shoe sole moulds. BLOOM, N. May 9, 1958 [Feb. 18, 1957], No. 5488/57. Class 87(2). The frame 4 of a mould for vulcanising shoe soles has a deformable lip 5 to provide an effective seal between the frame and the bottom plate 3. The lip may be provided by a marginal edge of a sheet 6 of e.g. steel, silicone rubber or a suitable synthetic plastic material secured to the underside of the main part of the frame 4 or it may be formed integrally with the frame e.g. of aluminium alloy. The deformation of the lip due to the pressure of the material 7 in the mould, e.g. sponge rubber, as it is vulcanised may be assisted by pressure applied by the last 1 acting downwardly on the frame. The lip 5 may not only project inwardly into the mould cavity but also downwardly towards the bottom plate 3 thus leaving a gap of 1 to 2 m.m. between the frame and the bottom plate.

Title: Improvements in impulse counting devices for use in telephone systems
IPC: H04Q3/42
Filed: 1924-03-07
Abstract: 231,305. Relay Automatic Telephone Co., Ltd.. and Ward, T. M. March 7, 1924. Automatic and semi-automatic exchange systems.-A relay counting chain having only one relav BK for each selectable circuit 1 - - 0 is so organized that the nth opening of an impulse circuit IW de-energizes relay BKn and energizes relay BK (n + 2). The relays BK are controlled by auxiliary relays MKO, MKE, the circuits of which are alternately prepared by alternate relays of the series BK. The circuits 5 for example is closed after the fifth opening of circuit IW if this opening is prolonged. The circuit IW may be closed either by the de-energization or by the energization of an impulse repeating relay, and in the latter case the first closure of the circuit IW may be prior to the first energization of that relay or may occur only after its first deenergization. The circuits are prepared by connecting battery to the wire H to energize BKI over circuit 2. BKI energizes BKII and MEO which lock themselves under control of MKE. Relay BKI opens its original circuit 2, but is locked by MKO to the wire IW. The first opening of IW unlocks BKI and so energizes BKIII over wire H and connects MKE to IW. The first re-closing of IW energizes MKE, which locks itself through a front contact of BKII, de-energizes MKO, and transfers the locking circuit of BKII to IW. The second opening of IW unlocks BKII and so energizes BKIV over wire H and connects MKO to IW. Relay MKE remains locked over a back contact of MKO. The second reclosure of IW energizes MKO. which locks itself through a. front contact of BKIII, de-energizes MKE, and transfers the locking circuit of BKIII to IW. Subsequent impulses act similarly. A relay DC2 is energized by MKE at the first impulse and is subsequently kept energized by MKO, MKE alternately. At the termination of the train of impulses a slow-acting relay closes a contact DC1 to complete a selected circuit. The counting chain can be used in an impulse recording set such as is described in Specification 181,119, or in conjunction with an operator's key-set.

Abstract: 549,824. Electric incandescent lamp-making machines. BRITISH THOMSON-HOUSTON CO., Ltd., EADE, S. R., and DAWSON, W. H. May 6, 1941, No. 5893. Drawings to Specification. [Class 39 (ii)] Incandescent lamps are "flash-aged" by mounting them singly or in groups on the rotating table of the machine and connecting each or each group in a circuit which includes a source of supply (through slip rings) and the secondary of an induction regulator which rotates with the lamps around its fixed primary. In this way the lamps receive the mains supply bucked or boosted by the regulator as the table rotates so that the lamps may be subjected to a particular programme of voltage treatment in a continuous fashion without breaking circuit at any stage. The induction regulator may supply the whole variable voltage without bucking and boosting the main supply. In a modification, the lamp may be carried by and connected to a secondary rotatable opposite a number of differently wound primaries connected to the supply so as to subject it to the desired voltage programme.

Title: Improvements in methods and apparatus for locating faults in electric cables
IPC: G01R31/08
Filed: 1942-05-01
Abstract: 557,088. Detecting and locating faults. LOVE, A., and CONRADI, E. S. May 1, 1942, No. 5919. [Class 37] A break in a conductor is located by applying between its free ends an alternating or intermittent potential, earthing one free end, and traversing the conductor with a search device having an open circuit whereof one end is inductively coupled with the conductor by the search device and the other end is coupled to earth. The apparatus shown includes means for detecting discontinuous conductors in a cable and also for locating the break in discontinuous conductors. In series with a battery 18 is the primary coil 19 of an iron-cored transformer 20 and a make- and-break device 14 having a resilient armature 114 and an earth connection 16. A condenser 12 and resistance 13 form a spark-suppressing circuit. A switch 22 has three contacts 23, 24, 25, the last of which is connected to a terminal 28. The secondary winding 30 of the transformer 20 is connected to terminals 33, 34 and to the contacts 35, 37 of a jack, the outer contact 37 being earthed. The terminal 34 is connected to terminals 41, 43. To detect a discontinuous conductor a plug connected to head phones is inserted in the jack 35, 37 and the switch 22 is engaged with the contact 25. Conductors are connected in turn between the terminals 28, 29, causing a sound in the phones if the conductor is continuous. To locate the break in a discontinuous conductor, one end of this conductor is connected to the terminal 33 and the corresponding ends of the remaining conductors of the cable are connected to the terminal 34. All the ends of the conductors at the second end of the cable are connected to the terminal 43, so that all metallic parts of the cable other than the part of the discontinuous conductor connected to the terminal 33 are at earth potential. The switch 22 is moved to the contact 24 and the plug is disconnected from the jack 35, 37 and inserted into a search device 48, Fig. 4, comprising a metal plate forming one plate of a condenser, of which the other plate is the conductor under test. This is passed along the cable from the earthed end until it reaches the break, which is indicated by the emission of a note of the impressed frequency in the head phones 54. An amplifier and loud speaker may be employed instead of the head phones, or a visual signal such as a lamp or gas discharge tube may be used. The signal potential applied may be of alternating, pulsating, or intermittent form. The plate 48 may be replaced by an inductance coil.

Abstract: A composition for rendering cellulosic fibrous sheet material non-adherent to normally adhesive materials, comprises an aqueous emulsion of a liquid methyl-hydrogenpolysiloxane of the formula <FORM:0693788/IV (a)/1> in which a is 1 to 1.5, b is 0.75 to 1.25, and a+b is 2.0 to 2.25, in an aqueous solution of a water-soluble cellulose ether, the emulsion containing 0.1 to 20 per cent by weight of the polysiloxane and 0.1 to 10 per cent by weight of the ether. The polysiloxanes employed may be cyclic or linear and may contain traces of hydroxy radicals.  The linear polymers may be end-blocked, e.g. with trimethylsiloxy or dimethylhydrogensiloxy units.  Cellulose ethers specified are methyl-and hydroxyphenyl-celluloses and the sodium salt of carboxymethyl cellulose (the glycollic acid ether of cellulose).  Emulsifying agents may be used in making the emulsions, preferably quarternary ammonium salts or higher aliphatic alcohol sulphates.  The polysiloxanes may be stabilized by adding an organic acid such as acetic acid.  Catalysts may be added to the emulsions, e.g. octoates, hexoates, acetates, oleates, stearates, naphthenates, laurates and resinates of lead, iron, zinc, copper, aluminium, magnesium, cadmium, cobalt, nickel and sodium, and sodium bicarbonate and aluminate.  The emulsions may be applied to all types of paper and paperboard and textile fabrics, by wetting the material therewith and drying and curing the wetted material, preferably at 40 DEG  to 200 DEG  C.  The treated materials may be used (1) for making containers into which hot asphalt or polymers such as polyisobutylene may be poured and solidified, (2) in contact with the adhesive surfaces of pressure-sensitive tapes, (3) for preventing sheets of rubber from adhering together, and (4) in lining boxes of partially baked bread goods.  In examples, aqueous emulsions of (A) a trimethysiloxy-end-blocked methylhydrogen polysiloxane and (B) zinc 2-ethyl hexoate catalyst, were made with the aid of a higher aliphatic alcohol sulphate.  Portions of A and B were added to aqueous solutions of different cellulose ethers and the resulting emulsions were used to treat kraft paper and paperboard.
