Abstract: 753,985. Wire terminals; sleeve couplings; cable clamps. SALVI, A., and TORRE, M. T. S., [trading as SALVI & C. GIA I. F. I., A.]. Jan. 15, 1954 [Jan. 16, 1953], No. 1288/54. Classes 36 and 38 (1). [Also in Group XXII] A connecting sleeve 1 for bimetallic conductors, e.g. conductors having a steel core and an aluminium mantel, has a uniform bore 2 and an extension 4 for attaching a branching lug 5 provided with a similar extension 6. The end of the sleeve for receiving a steel anchoring eye (Fig. 5) is provided with a polygonal seat 3 for accommodating the polygonal portion 10 of the eye. The eye consists of a smooth stem 7 provided with a bore 8 for receiving the core of the conductor, a solid corrugated portion 9 followed by the polygonal portion 10, a circular plate 11 and an eye 12. A button for attachment to double socket elements for anchoring main bars for sub-stations may take the place of the eye 12 (Fig. 9, not shown). In assembling, the sleeve is fitted on to the conductor, then, after the steel core has been inserted in the bore 8 of the steel eye, the sleeve is slid over the eye until the seat 3 fits into the polygonal portion 10 of the eye whereupon the sleeve is compressed on the eye by means of a hexagonal die, as shown in Fig. 15. For joining bimetallic conductors together, an aluminium sleeve 14 (Fig. 10) is used in conjunction with a steel jointing sleeve 16 (Fig. 11). The steel cores of the two conductors are inserted into the steel sleeve 16 which is compressed and then inserted into the aluminium sleeve 14. Finally the sleeve 14 is compressed to lock the sleeves together. An aluminium connecting sleeve 18 (Fig. 12) for connecting a monometallic conductor to an anchoring element is provided with a bore portion 19 for receiving the whole of the conductor, a reduced portion 20 for receiving the conductor less one or more layers of wire and a bore portion 21 for receiving the steel eye (Fig. 13) which has a solid corrugated stem 22 terminating in a cylindrical end 23. The sleeve also has a polygonal portion 24 for receiving the polygonal portion 25 on the eye. The compression of the sleeve on to the conductor and the steel eye is effected as hitherto by a hexagonal die. A sleeve for joining monometallic conductors together is provided with two aligned bores 28 (Fig. 14) connected by a central bore 29 of reduced diameter for receiving end portions of said conductors deprived of one or more outer covering layers.

Title: An improved electric supply meter
IPC: G01R11/00
Filed: 1937-01-19
Abstract: 489,038. Recording-apparatus MATHER, J. B., and SHROPSHIRE IRON CO., Ltd. Jan. 19, 1937, No. 1565. [Class 106 (iv)] [Also in Group XL] A meter for recording the consumption of a commodity is provided with means for marking a record strip every time a given quantity of the commodity has been metered, the strip also having a time scale in which the distances between the graduations correspond to equal time intervals. In one form, Fig. 1, a cam 4 driven by an electricity meter operates a rod 6 every time a given quantity of energy (say 10 units) has been consumed. The rod 6 depresses a marker 10 to mark a clock-driven strip 2. Every time a larger quantity of energy (say 100 units) is consumed, another cam 5 depresses another marker to record on the clock-driven strip 2. Alternatively, the cam 5 may deflect the first marker so that every tenth mark is displaced across the strip. The cam 5 may also cause the total number of units consumed to be printed each time the said cam operates. The strip may have a time scale marked on it or may be marked at regular time intervals to provide this scale. In a further modification, Fig. 5, a disc 24 secured to the meter spindle has ten equally-spaced holes 24a which allow light to pass from a source 18 to a light-sensitive cell 19 every time the given quantity of energy is consumed. The light-sensitive cell controls apparatus which causes the energization of an electromagnet 20 to depress a marker 10 on to the clock-driven strip 2. The disc 24 has an additional hole 24b which, once in each revolution, allows light to pass to a cell 23 to cause the energization of an electromagnet 25 operating a marker 16. In place of the light-sensitive devices the electromagnets 20, 25 may be controlled by contacts on the registering spindles of the meter. Instead of using the markers shown, the record may be made by a spark. Several remote recorders may be electrically operated from a single meter.

[Class 80 (ii).] Relates to means for braking reaction drums in change-speed epicyclic gearing especially of the Wilson type and as applied to vehicles. Each brake is applied by fluid under pressure so that power can be used as distinguished from manual effort as in the bus-bar arrangement of Specification 328,660, [Class 80 (ii), Gearing, Variable-speed &c.]. Around each reaction drum 3 is a band brake 2 with one end anchored at 6 to a fixed casing member 4. Around the brake 2 and inside the casing 4 is an expansible tube 1 adapted to be supplied through a duct 5 by fluid from a power pump, not shown. The pressure fluid expands the tube 1 inwards so as to apply the brake 2 forcibly upon the selected drum 3 and uniformly round the drum. The drum is thus held quite stationary with very little effort on the part of the driver. On release of the pressure, the drum is freed. The fluid may be liquid, gas, or vapour. The Provisional Specification enumerates Specifications 164,042 and 312,128, [both in Class 80 (ii), Gearing, Variable-speed &c.], as examples of the Wilson type change-speed gearing.

Filed: 1939-01-21
Abstract: 521,034. Upholstery stuffing. WHITELEY, E. O. Jan. 21, 1939, No. 2188. [Class 15 (ii)] A dry loose mass of stuffing fibres is prepared by coating the individual fibres with a resilient film of rubber and subjecting them to a treatment whereby the fibres are unattached at points of crossing. The surface of the film may be treated so as to be wrinkled or roughened. Before or after the rubber coating has become firmly set, the fibres may be subjected to a picking or willowing operation so as to fluff up the coated fibres so as to prevent or remove adherence of the fibres at points of crossing. Coating of the fibres may be effected by immersing them in a liquid containing rubber or latex, the surplus being removed by centrifuging. The coating mixture may contain latex, vulcanized or chlorinated latex, and glue, starch or casein. The coating mixture may be in aqueous suspension and it may be passed through a homogeniser before use. Alternatively it may contain chlorinated rubber in a volatile solvent. The fibres used may be of cotton, wool, feathers, wood, sisal, hemp, sugar cane, redwood or other bark, or glass including glass wool. Before being coated with rubber, the fibres may be treated with a coagulant for the rubber, e.g. cotton fibres may be passed into a heated chamber containing steam and acetic acid or formaldehyde vapour. Crinkling of the coating may be effected by rapid heating, or by immersion in benzine, carbon tetrachloride, or caustic soda. Glass fibres may be heated and dipped into a solution of molasses, centrifuged, and dried, prior to the process of coating with rubber.

Title: Oligomers of olefines
Inventor: PARKER FREDERICK
IPC: C07C2/08
Filed: 1965-01-19
Abstract: C5- 8 olefins are oligomerized in the liquid phase in the presence of a synthetic petroleum cracking catalyst, the conversion of the olefin being maintained at a constant level by progressively raising the reaction temperature, and the catalyst being periodically regenerated. The space velocity of the liquid olefin is preferably below 3 vols./vol. of catalyst/hour, and the conversion of olefin per pass is preferably less than 30%, the starting temperature being adjusted accordingly (e.g. 50-150 DEG  C.), and unconverted olefin being recycled.  Suitable catalyst are silica/alumina, silica/magnesia, silica/zirconia, silica/boria, or any of these plus a transition metal oxide, e.g. nickel oxide. The process is illustrated with reference to the dimerization of a mixture of n-hexenes, a typical progressive temperature rise (Example 1) being from 67 DEG  to 130 DEG  C. over a period of 95 hours.
