Patent GB-1170331-A (GB)
Title: Telephone Exchange
IPC: H04Q3/00
Filed: 1967-02-10
Abstract: 1,170,331. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 10 Feb., 1967 [11 Feb., 1966], No. 6519/67. Heading H4K. In a PABX, certain extensions are provided with an indicator panel which provides a visual display of the number of the calling party. A calling line, e.g. NSt, is connected via the multistage network KF1, KF2 to a service extension SSt, e.g. a hotel waiter. Immediately the connection is set-up or as soon as the wanted extension replies a start circuit SpK applies a signal to the exchange line identifier IdE which determines the identity of the caller and passes it via SpK and an individual wire SL to the called extension's indicator A. During such an identification, the other service extensions are locked out. At the end of the call the display is automatically or manually cancelled. An extension such as FM is rung in case of fire. As soon as the caller hears this extension being rung he may hang-up since identification takes place automatically for fire alarm calls and erasure of the display can only be effected manually. An audible alarm is given.

Title: Process and apparatus for producing heat-recoverable articles
IPC: B29C48/06
Filed: 1964-02-17
Abstract: 1,046,367. Moulding hollow articles. RAYCHEM CORPORATION. Feb. 17, 1964 [Feb. 18, 1963], No. 6567/64. Heading B5A. Heat shrinkable end caps are produced by forming a tube of thermoplastic polymeric material, heat sealing spaced wall portions of the tube to form a plurality of isolated cylindrical tubular portions, cross-linking the polymeric material and expanding and setting the tubular portions to produce heat shrinkable tubular portions each having a final diameter greater than its initial diameter. Thermoplastic tubing 12, of polyethylene, polypropylene, vinyl polymers, vinyl chloride/vinyl acetate polymers or polyamides, capable of being crosslinked, is extruded into a cooling bath 14 in which a sealing assembly 15 (Fig. 4, not shown) pinches the wall tubing at spaced intervals whilst the interior wall is still plastic, to form tubular portions 12a, spaced apart by sealed portions 12b, the sequentially sealed tubing then being fed to a chamber 17 in which by means of high energy radiation, cross-linking of the polymer is effected. The tubing is then intermittently fed through a glycerine heating bath 30 into the expansion assembly 25 where each portion 12a is blown up into portions 12c and 12d linked by an unexpanded portion 12f, the material being chilled as it makes contact with the die walls 50 (Fig. 7, not shown) to set it in the expanded form. The tubing is then cut at station 28 to form heat shrinkable end caps. In modifications to the process, the sequentially sealed tubing may be cut to shape before further treatment, the cross-linking performed by chemical methods, and the material expanded by, reducing the pressure on the outside of the tubing, injecting chemicals which generate a gas on heating, or liquid under pressure into the tubing, or stretching the tubing over a mandrel.

Filed: 1969-02-07
Abstract: 1,241,093. Conveyer systems. A. FREEMAN. 7 Feb., 1969, No. 6704/69. Heading B7L. A conveyer, e.g. for shoe components comprises carriers 2 movable along a track 1 by a reciprocating toothed band 6, each carrier having means for disengageable coupling with the band and a device for operating this means upon encroachment on a preceding carrier, a collapsible drag link between each carrier and the next, allowing lost motion therebetween, and a stop 36 on the track for operating the disengageable coupling means of a carrier to cause that carrier and, therefore, following carriers to come to rest, preceding carriers pulling the leading stationary carrier past the stop 36 when the lost motion has been taken up. The toothed band 6 engages a pivoted plate 23 to drive the carrier, the plate 23 being mounted on a strip 20 pivoted at the rear axle 19. A tongue 20a of that strip engages a lip 27 on the body of the preceding carrier to lift the pivoted plate 23 out of engagement with the band 6. Such disengagement is also produced by a projection 26 at the side of the strip 20 encountering the stop 36. By tilting of the carrier when it is unloaded the plate 23 may also be disengaged from the band 6. A switch may be mounted on the track and operated by a passing carrier to stop the drive motor 12 and start a timer to re-start the motor after a pre-set interval.

Filed: 1972-02-16
Abstract: 1376830 Treating coke-oven gas: sulphur: nitrogen CARL STILL 16 Feb 1972 [16 Feb 1971] 7163/72 Heading C1A Coke-oven gas is scrubbed to remove hydrogen sulphide, and scrubbed to remove ammonia, the ammonia being desorbed from the scrubbing solution and the H 2 S scrubbing solution being regenerated, the gaseous products of the regeneration step being used to combust or decompose the desorbed ammonia. The gaseous products of the combustion step may be mixed with the heating gases for the coke-oven battery or may be used as fuel in the flues of the cokeoven battery. The gaseous products of the regeneration may be used to desorb and decompose ammonia from the ammonia scrubbing solution or employed as combustion air in a sulphuric acid plant. The H 2 S scrub may precede or follow the NH 3  scrub, the preferred scrubbing solution comprising an aqueous solution of Na 2 CO 3  containing 9,10-anthraquinone-1,7-disulphonic acid as a catalyst. The spent absorbent may be oxidized by blowing in air thus producing sulphur, which may be filtered off from the aqueous carbonate solution. The regenerated carbonate may be recycled to the H 2 S scrubber. Water resulting from the distillation of coal to form coke may be used to absorb the ammonia.

Abstract: 250,208. Deguide, C. April 3, 1925, [Convention date]. Purifying saccharine liquids.-Barium silicates, including the mono, di, and tri-barium silicates, and the silicates intermediate between the mono- and di- and between the di- and tri-barium silicates, when they have become contaminated with silica or alumina in use, for instance, in the treatment of sugar solutions and subsequent regeneration, are suspended in water and treated with carbonic acid to convert the barium into carbonate with the separation of silica and alumina. The insoluble material is then treated with caustic soda or potash to dissolve the silica and alumina, leaving barium carbonate which is then calcined with silica to produce the original barium silicate. The treatment with carbonic acid need not be complete, but may be discon. tinued when the necessary amount of silica has been removed, so that the product when calcined will be again suitable for the treatment of sugar solution. Specifications 110,537 and 174,052. both in Class 1 (iii), Oxides &c., Metallic], are referred to.

Abstract: 1,080,881. Disc brakes. GIRLING Ltd. March 19, 1964 [Feb. 26, 1963], No. 7645/63. Heading F2E. In a disc brake of the kind in which friction pad assemblies are adapted to be brought into engagement with opposite faces of a rotatable disc, the friction pad assemblies being located in a caliper which straddles a portion of the periphery of the disc, a friction pad assembly 14, 15 is guided for movement towards and away from the disc by oppositely inclined torque-taking guides formed by surfaces 18, 19 in the split caliper 10, the guiding surfaces 18, 19 co-operating with complementary inclined end surfaces 16, 17 on the friction pad whereby a servo or self-energizing action is obtained in both directions of rotation of the disc. The embodiment shown discloses friction pad assemblies on each side of the disc actuated by inclined piston and cylinder mechanisms 24, 23. In a modification, the innermost and outermost edges of each friction pad assembly may be inclined with respect to the axis of the disc whereby as the friction pad wears and the pad assembly moves outwardly the effective centre of pressure of the friction pad moves inwardly through substantially the same distance and remains substantially at the same effective radius throughout the life of the pad. The invention is applicable to disc brakes of the single-sided type in which either the caliper or the disc is axially movable and only one friction pad assembly is directly actuated, the other pad assembly being brought into engagement with the disc by the reaction on the caliper or disc.
