Title: Torque-controlled couplings
IPC: F16D7/06
Filed: 1973-10-31
Abstract: 1411468 Torque-controlled coupling RING- SPANN ALBRECHT MAURER KG 31 Oct 1973 [29 Dec 1972] 50667/73 Heading F2U In a torque-controlled coupling, rotary motion is transmitted from an inner coupling member 1 to an outer coupling member assembly 6, 6<SP>1</SP>, by roller pairs 2, 3, each pair being carried in a circumferential recess 9, Fig. 3, in flange 8 of coupling member 1, and each pair being subjected to a compressive spring force between a flat bearing surface 7 on member 6 and a cam recess 4 out into the face 5 of the axially resilient member 6<SP>1</SP>. Member 6<SP>1</SP> may be of steel, and may have interleaved slits 10 cut into its tubular wall, and the overall axial resilience of the assembly may be modified by the addition of selected helical compression springs 11, each guided by a sleeve 19, and trapped by the disc 21 and setscrews 20, which also secure together members 6 and 6<SP>1</SP>. Torque in excess of a predetermined limit will cause a rolling excursion of roller 3 on cam surface 4, resulting both in an axial compression of member 6<SP>1</SP>, and also a rotary displacement of members 6, 6<SP>1</SP>, relatively to member 1. This axial compression may be monitored by spring-loaded pins 13, bearing against flange 23 of member 6<SP>1</SP>, and the resulting axial displacement of an external disc 14 may be used to actuate a limit switch or an electronic proximity switch 15, in order to cut out the drive power from an external source. The relative rotary displacement may be limited in angular extent by the addition of a positive stop pin 16, engaged in a circumferential recess 17. A viscous damping fluid may be introduced and retained within the housing formed by members 6, 6<SP>1</SP> and 1. A loose annular disc may be interposed between rollers 2 and rollers 3, providing rolling surfaces on both sides. Roller members 2 and 3 may alternatively be mounted rotatably on axes arranged around a cylindrical boss, and may be located in a staggered formation.

Abstract: 1,236,495. Battery terminals. SEMPERIT A.G. 23 Oct., 1969 [25 Oct., 1968], No. 51957/69. Heading H1B. The lead terminal of a secondary cell comprises a shell having one or more circumferential ribs on its outside, at least one rib being thinner at its base than at its apex. As shown in Fig. 4 the shell 1 carries two circumferential ribs 2<SP>1</SP>, 4 having a reversed taper and forming a dovetail joint with the cell cover 7 which is injection moulded around the terminal. Shrinkage of the material, e.g. hard rubber, of the cover forces the material in the dovetail against the ribs forming a tight seal. In other embodiments the lower rib 2 is untapered and braced by fillets to the shell (Fig. 2, not shown), and the shell is curved outwardly between the ribs so that after the cover shrinks it springs back against it (Fig. 5, not shown). The terminals are made by casting with the taper of the ribs on the outside (Fig. 3) and bending the tapered ribs inwardly to the position shown in Fig. 4.

Title: Improvements in or relating to conference circuits for time division switching systems
Inventor: GAUNT WILMER BARSEAU
IPC: H04Q11/04
Filed: 1964-12-23
Abstract: 1,088,702. Automatic exchange systems. WESTERN ELECTRIC CO. Dec. 23, 1964 [Dec. 30, 1963], No. 52205/64. Heading H4K. A T.D.M. system utilizing resonant transfer techniques is provided with conference call facilities. In the conference circuit, the storage capacitance comprises two capacitors 23, 24 in series, the value of each capacitor being twice that of any of the subscriber's capacitors CX to CZ whereby the impedance on both sides of the highway 12 is the same. To the junction of the series capacitors, a further storage circuit 26, 25 is resonantly connected. The latter circuit is used for storing a portion of the charge i.e. that on 24 placed in the storage circuit 22, 24 by capacitor CX, say, whereby during the time slot (Ty) allotted to Y, capacitor 23 can supply energy to CY whereafter the energy stored in 25 is reinserted in 24 so that it can then be passed on to CZ during TZ. It is thus ensured that every subscriber in the conference receives an adequate signal from every other subscriber. The line gates and conference gate SW1 are opened for 0À8 Ásec. of each relevant time slot whereby a half-cycle oscillation is transferred between stores. The second conference gate SW2, which may be controlled by a pulse distributer 15 or by a monostable circuit triggered by SW1 over lead 28 opens for the remaining 0À4 Ásec. of each time slot, inductance L<SP>1</SP> being chosen appropriately. The further storage circuit 26, 25 may comprise only an inductor (but no details of the switching time required in this case are given). It is shown mathematically that residual charges, which are returned to the line stores because of this method of operation, do not affect subsequent transfers (Fig. 2, not shown). The average current, voltage and impedance of the line circuits when connected to such a conference circuit are calculated.

Title: Production of heat-resistant organic foam synthetic resins
Inventor: STASTNY FRITZ
IPC: C04B28/26
Filed: 1964-12-29
Abstract: Heat-resistant organic foam materials are prepared by introducing into an aqueous solution containing alkali metal silicate, which may contain suspended solid water-containing alkali metal silicate, expandable finely divided synthetic resin in such quantity that the ratio of the weight of added synthetic resin to the weight of anhydrous substances contained in the solution or suspension is from 1:9 to 9:1 (preferably 3:7 to 7:3) and then foaming the mixture at a temperature above the softening point of the expandable synthetic resin to form a homogenous foam material.  The mixture may be solidified at a temperature below that at which foaming takes place, prior to expansion. Substances which react with alkali metal silicates to form water-insoluble silicates, e.g. zinc oxide, talc, asbestos flour, magnesium oxide or calcium carbonate may be added to the solution before the addition of the synthetic resin particles. Fibrous materials, metal cloth or plastic cloth and mineral fibre mats may be added to the mixture, prior to expansion, to increase the mechanical stability of the foam.  1 to 10% by weight of polyhydric alcohols, e.g. glycerin and sugar such as cane sugar, may be added advantageously. The synthetic resin particles used may be pre-foamed but capable of further expansion.  Suitable particles consist of polystyrene or copolymers of styrene with acrylonitrile, acrylic acid and butadiene.  Particles based vinylidene chloride or chlorinated polyvinyl chloride are also suitable.  Suitable expanding agents are one which do not dissolve the particles or only slightly swell them, e.g. aliphatic hydrocarbons such as propane, n-butane and n- or iso-pentane. Powdered expanding agents which liberate gas at elevated temperature, e.g. azodibutyronitrile, may also be used.  The synthetic resin particles may be made flame retardant by adding inorganic halogen compounds or by mixing with chloroparaffin powder or antimony trioxide.ALSO:Formed synthetic resin material containing alkali metal silicates (see Division C3) may be provided with a protective layer, for example by applying lacquers of epoxide resins, polyamides, polyvinyl chloride or copolymers of vinylidene chloride and other polymerizable substances or by applying a coat of plaster. Synthetic resins specified are polystyrene, styrene-acrylonitrile, acrylic acid-butadiene, polyvinylidene chloride, chlorinate polyvinyl chloride.  Fibrous materials, metal cloth, plastic cloth, mineral fibre mats may be added to the foamable synthetic resin mixture.

Abstract: 1,210,824. Rotary positive-displacement pumps and motors. BORG-WARNER CORP. Nov.20, 1967 [Dec.5, 1966], No.52686/67. Heading F1F. A reversible gear-pump, or motor, has a pressure-loaded wear-plate 30 abutting externallymeshing gears 13, 14 and carrying a flexible and resilient seal 80 in a groove 66 on its side farthest from the gears, lips 87, 88 being deflected by the sides of the groove so as to press the wear plate against the gears. The seal has radial portions that lie in similar portions 70--73 of the groove. The wear plate is movable transversely of a plane containing the axes of the gears so that working fluid on the high-pressure side of gears acts upon the edge of the wear plate and presses portions 58, 59, or 60, 61, of the latter against the housing to prevent back-flow around said edge. High-pressure working-fluid thereby gains access to a channel 89 through grooves 75--78 to load the seal and to spaces between the wear plate and the housing bounded by the seal on the high-pressure side to load the wear plate. Compensation for the pressure gradient across the gears is provided by the working fluid on the low-pressure side entering a space behind the wear plate between the radial portions 70, 71, or 72, 73, of the groove. In one modification, Fig.16 (not shown), the seal has a substantially rectangular cross-section. In another modification, Figs.17 to 24 (not shown), the seal is similar to that shown save that it has flexible and resilient projections (117) abutting the bottom of the groove, a rigid sealing- member (110) being placed between the seal and the housing.

[Also in Division B3] A stamping die, Figs. 1-5 (not shown), comprises a plastics base (4b) and a shell (3) formed of metal laminµ. Depressions (4a) in the die may be filled with metal, plastics or a metallized material. The die is made by successively pressing the laminµ over each other in a matrix (Fig. 5), using a rubber bolster. Each lamina may be spot welded (at 7) to the underlying lamina, or a bolt on the inside of the outer lamina may pass through holes in the others. After removal from the matrix, a plastics material is moulded into the depressions (4a), or these are filled, at least partially, with metal or metallized material. The base (4b) is then built up in layers of plastics with intermediate layers of glass fibre. A matching die may be formed in the same way using a further matrix, or the built-up die may be used as the matrix and coated temporarily with additional laminµ to take the place of a workpiece. The outer lamina may be replaced when worn.
