Title: Process for the hydrogenation of catalytic reformates
IPC: C10G69/08
Filed: 1955-11-11
Abstract: A catalytic reformate is subjected to a mild catalytic hydrogenation process at 0-500 p.s.i.g. and 300-500 DEG F. to reduce the loss in octane number on exposure to air and light.  The process is particularly valuable for reformates obtained using a platinum catalyst.  Other conditions which may be used include a space velocity of 0,1-1,0 V/V/Hr., and 2,000-4,000 S.C.F./barrel of feed of hydrogen or hydrogenrich gas using a hydrogenation catalyst comprising one or more sulphides of Group VI or VIII metals, particularly a mixture of nickel and tungsten sulphides.  The fraction of the reformate boiling between 100 and 138 DEG C. only may be treated and the hydrogenated product recombined with the remaining portions of the reformate.  The process may be carried out as a continuous process with the reforming operation.

Title: Improvements in inflatable balls
IPC: A63B41/04
Filed: 1925-12-22
Abstract: 250,903. Wilson-Western Sporting Goods Co., (Assignees of Turner, A. J., and Wilson & Co., T. E.). April 20, 1925, [Convention date]. Balls.-In an inflatable ball of the type having a laced opening and a bladder with an inflation valve stem accessible through a hole in the casing, a resilient cushioning member having an aperture is permanently connected to the inside of the casing with the aperture in register with the hole in the outer casing, the valve stem being adapted to be detachably mounted in the aperture. In Figs. 2 and 3 are shown respectively a section across the case opening of a basket-ball, and an interior view of the parts. At each side of the casing 11 folded reinforcing-strips 12, 13 of leather are sewn to the casing so as to form lacing-loops 17, 18 through perforations in which the lace 19 is threaded in the manner shown in Fig. 3. The lacing is thus hidden from view and is removed from contact with the fingers of the players. The rubber bladder 20 has secured thereto a metal valve stem 21 containing the usual " valve inside." The stem screws into a flanged sleeve 26, embedded in a rectangular rubber cushion 25 reinforced by fabric and secured by stitching, and by cementing if desired, to the casing and to its reinforcing strip 12. The surface of the cushion adjacent the bladder is of convex formation. A hole 24 through the casing and through the reinforcing strip 12 allows a pump to be screwed into the valve stem 21 for the purpose of inflating the bladder. The stitching securing the cushion 25 is a sufficient distance from the flange of the sleeve 26 to allow the sleeve and its attached valve stem to yield when the ball is in play. In a modification, Fig. 7, applied to a football, the reinforcing strips instead of being looped consist of single layers 43, 44 of leather attached to the case, and the lace holes are made both through the reinforcing strips and the case. The lace 50 is threaded through the holes in the manner shown and thus appears on the outer surface of the case as a series of parallel portions extending across the case opening.

IPC: H01H3/00
Filed: 1960-09-21
Abstract: 992,936. Counters. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 11, 1961 [Sept. 21, I960], No. 32438/60. Heading G4D. [Also in Division H2] An electrical contacting device for a tachometer generator is operated by a continuously rotating driving wheel 12 and comprises a set of contacts 7 operated by a rocket wheel 2 which is first rotated in one direction; by pins 14 of wheel 12 engaging teeth on the wheel 2, through a predetermined angle against the restoring force of a spring (Fig. 2, not shown), such that when the wheel 2 is suddenly released it swings back past its control position and a nylon cam 3 thereon momentarily closes the spring contacts 7 against the restoring force of the spring in the other direction, wheel 2 then returning to its central position. Thus the contacts 7 close once for each revolution of wheel 12, which has a high moment of inertia and is statically balanced. Wheel 12 is driven through reduction gearing 13 from the track wheels of a road or railway vehicle to operate a recorder device. The operation period of the contacts remains substantially constant irrespective of the speed of the wheel 12.

Filed: 1959-09-24
Abstract: 935,743. Hydraulic accumulators. J. MERCIER. Sept. 24, 1959 [Sept. 29, 1958], No. 32529/59. Class 69 (2). A separator for dividing the interior of an hydraulic accumulator into two compartments comprises a flexible partition 31, Fig. 5, having a mouth and a rigid annular support member 36 to which the partition is bonded and thereby secured to the accumulator, the mouth of the partition extending outwardly in the radial direction towards the support member. The inner fibres of the material of the partition adjacent the support member are shorter than those near at least one wall surface of the partition so that deformation of the partition due to tension causes less movement of the external surfaces than of the interior of the material. In order that the external fibres shall be longer than the internal fibres, the crosssection of the separator may be shaped as shown at 22, 23 and 26 in Figs. 2, 3 and 4, respectively, and adhered to flat, convex or concave support members. The embodiment shown in Fig. 5 incorporates the arrangement shown in Fig. 2, the partition 31 being adhered to a triangularshaped support member 36 and secured between a casing 30 and cover 32 by U-shaped segments 39 held in position by a steel strip 40. In other embodiments, the separator is bonded to a part-toroidal shaped support member 54<SP>1</SP>, Fig. 7, or to a circular section support member, the separator being clamped between the cover and casing by deforming the cover or by separate clamping means. Specification 935,744 is rereferred to.

Abstract: 1,153,041. Pipe couplings. GERMANY, MINISTRY OF TRANSPORT. 20 July, 1966, No. 32599/66. Heading F2G. [Also in Division H2] In an automatic coupling, shown in plan, for rail vehicles, a movable cover 7 protects electric contacts 4 and air conduits (2) (Figs. 5, 6, not shown) when the vehicle is not coupled, the action of coupling sliding the cover 7 from the closed position (Fig. 1) to the fully open position (Fig. 3) and causing a dependent movement of the support 3 of contacts 7 so that the contacts 7 and air conduits touch the corresponding contacts of the coupled vehicle. The motion of the cover 7 is connected to that of contact support 3 by a bent lever 8, pivoted at one end between projecting guides on cover 7 and at the other to a shaft 10 on a pedestal 6 on coupling 1. A torsion spring 11 tends to pivot the lever 8 in a clockwse direction, i.e. to urge the cover 7 to the closed position. As the cover 7 approaches the fully open position, a cam 9 on the lever acts on a stop 13 on connecting member 12 to raise it and, via a drawbar linked to the short arm of lever 15, to move the contacts 4 outside the housing. Pressure spring 14 tends to hold these contacts in the retracted position. For servicing purposes the cover 7 may be moved manually to a half open position (Fig. 2, not shown) whereby access to the air conduits &c. is provided but the electrical contacts 4 remain retracted. A pivoted locking means 18 (see also Figs. 4-6, not shown) retains the cover 7 in this position.

Filed: 1930-10-31
Abstract: 365,671. Casting floors in situ. AIREY, SIR E., 7, Blenheim Terrace, Woodhouse Lane, Leeds. Oct. 31, 1930, Nos. 32725/30, 35774/30, 38400/30, and 9310/31. [Classes 20 (ii) and 20 (iv).] Floors or stairs are cast in situ so that minor beams are formed between the main and transverse beams by the use of meshwork channels or domes which may be separately supported on shuttering or supported by the ceiling lathing. The domes 23 may be formed with their lower edges flanged and adapted to engage the ceiling lathing 7, or may be formed integral with the lathing or be secured thereto by wire. The open ends of the domes may be closed by means of metal, wood, pulp, papier-mÔchÚ, asbestos, plaster or other substances, and the bottoms may be formed integral with the dome. The ceiling lathing may be stiffened by ribs or projections, and the domes may be ribbed in either r direction. The domes are joined together by shaped distant pieces 21 which are perforated to receive the rib reinforcing rods 55, Fig. 26, and which may be used in staggered positions to give varying widths of beam. Where sprinkling or heating pipes are to be laid in the floor, the bases of the domes are formed in two parts which have an overlapping joint at the position of the pipes 47, Fig. 22, which are supported by hangers 50. For floor portions at stairs, the domes are wedge-shaped, and are either supported on the ceiling lathing, or the bases 52 of the domes form the ceiling lathing. The Provisional Specification describes also the use of wood, wood pulp, papier-mÔchÚ, asbestos, cardboard or concrete for the domes or channels, or a combination of these materials with metal.

Title: Improvements applicable to electro-magnetic relays and like apparatus
IPC: H01H47/12
Filed: 1930-10-31
Abstract: 366,558. Electromagnetic relays. CLUDERAY, E. S., Ramsgill, Church Avenue, Farnborough, Hampshire, and RADIOVISOR PARENT, Ltd., 28, Little Russell Street, London. Oct. 31, 1930, No. 32784. [Class 38 (v).] In a sensitive relay in which the current through the energizing winding may be controlled by a photo-electric cell, the relay is arranged so that the field acting on the armature is modified after attraction by the movement of the armature of a secondary relay mounted in close magnetic juxtaposition to the sensitive relay so that on the sliglitest diminution of the energizing current which caused attraction of the armature, the armature will be released. As shown in Fig. 1 a polarized relay having a pivoted armature 2 working between poles NS of a permanent magnet 1 and surrounded by an energizing coil 3 in the circuit of a photo-electric cell 100, the armature is held with its contact 6 engaging the lower contact 8 until an increase of current in the coil 3 causes the armature to move upwardly so causing the engagement of its contact 6 with the upper contact 9. This completes the circuit of a winding 5 around the armature 2 to maintain the armature in the raised position and a winding 15 on an auxiliary polarized relay so causing the attraction of the armature 11 of this relay. The function of the winding 5, which is of small value compared with the main winding 3, is to maintain the armature 2 in its displaced position until the armature 11 of the secondary relay commences to move. The two relays are mounted in close magnetic juxtaposition as shown in Fig. 2, and the change of field in the relay 10 caused by the travel of the armature 11 is arranged so that the current in the winding 3 which caused attraction of its armature is just sufficient to maintain the armature 2 in its raised position and on any decrease in current in the cell 100 the armature is released. The armature 11 is maintained in its raised position by its magnetic bias until the sensitive relay is restored to its original position by a fall of current in the winding 3, when the circuit of a restoring coil 14 is completed in series with a temporarily energized coil 4 which holds the armature 2 down until the armature 11 has been restored, and the relay 1 is in readiness for a subsequent operation. A local circuit may be completed by the secondary relay 10 at contacts 13, 19. In order to produce an increased travel of the polepieces of the sensitive relay the polepieces may be shaped (Figs. 3 and 4, not shown) to produce a magnetic field at an angle to the direction of motion of the relay armature.
