Title: Method of making a composite sheet of aluminium alloys or of aluminium and aluminium alloys
IPC: B32B15/01
Filed: 1970-04-14
Abstract: 1311970 Jointing by rolling; making composite sheets CEGEDUR GP 14 April 1970 [16 April 1969] 17662/70 Headings B3A and B3M [Also in Division C7] A composite sheet of aluminium alloys, or of aluminium and at least one aluminium alloy having local variations in composition on its surface so as to produce tint variations when anodized, is formed by jointing by hot rolling a composite cover sheet formed of at least two aluminium alloys, or aluminium and at least one aluminium alloy and having local composition variations on its surface to a thicker aluminium or aluminium alloy plate and further rolling the assembly to less than <SP>1</SP>/ 15  of its original thickness, e.g. <SP>1</SP>/ 500 . The ratio between the thicknesses of the thicker plate and cover sheet before jointing is at least 5 : 1, e.g. 20 : 1. In an example, the surface layer of an Al-Si alloy and the subjacent layer of an Al-Mn alloy of an Al-Si : Al-Mn composite is locally melted in desired areas to cause the two alloys to mix thereby producing local composition variations. The Al-Mn side of the composite is then joined by hot rolling to a thicker plate of Al-Mn-Mg alloy, and the assembly further rolled. The rolled composite is subsequently anodized to form the tint variations.

Title: Improvements in or relating to road, railway, or other vehicles
IPC: B60J7/10
Filed: 1925-07-10
Abstract: 259,315. Sparshatt, J. H. July 10, 1925. Addition to 248,949. Covers, wagon and like.-In order to adapt the sliding tilt or roof described in the parent Specification for use with a vehicle having a long body or platform, the forward support for the tilt 2, Fig. 1, is formed by extending the roof of the cab, or by the provision thereon of an extended runway, e.g. by hinged extension brackets 1, so as to allow for the longer travel of the tilt. In addition, suitable transmission means, e.g. a wire rope passing round pulleys, operated either by hand or by power, are provided for moving the tilt. Bulging of the sides of the tilt when heavy loads are being carried is prevented by strengthening the sides, a preferred arrangement comprising steel channels 9, Fig. 4, on the lower edges of the tilt provided with rollers 12 adapted to run on rails 10 fixed to brackets 11 on the vehicle sides. For locking the tilt in the closed position downwardly extending plates 13, Fig. 5, slotted at 14 are engaged with screw bolts 15 on the vehicle sides and locked by lever or fly nuts 16. Entrance of rain, dust &c. at the gaps between the tilt and the fixed parts is prevented by the provision of rubber or like strips between contacting or cooperating surfaces on the relatively moving parts. Thus, in the arrangement shown in Fig. 8, where the tilt has a fixed portion 24 serving as the forward support, the upper rear edge of the part 24 has a rib 20 adapted to abut against a headboard 19 extending across the open front end of the tilt. At the sides fiaps 22 are hinged to the front edges of the tilt and provided with rubber or like strips 23 on their free edges adapted to make contact with the sides of the forward support 24, the necessary contacting pressure being obtained by the tightening up of the nuts 16.

Title: Improvements in fluid supply systems
IPC: F04C14/02
Filed: 1952-07-15
Abstract: 711,727. Rotary pumps. GENERAL MOTORS CORPORATION. July 15, 1952 [Aug. 10, 1951], No. 17797/52. Class 110(2) A fluid. supply system comprises two constantly-driven pumps, the supply from the second pump 12 normally returning to source 14 under control of valve means 48 actuated by delivery pressure of the first pump 11. A valve piston 49, whose upper surface is under pressure of the delivery of the main pump 11, moves downwards when that pressure rises, and allows the fluid delivered by pump 12 to pass through a chamber 44 into a pipe 32. Pressure from the pump 12 acts on the lower face of the piston 49 and the upper face of a plug 48. The effective area exposed to the discharge pressure of pump 12 is thus less than that exposed to the pressure of pump 11. A pipe 18 may feed lubricators 19 with fluid constantly, and a pipe 23 may feed fluid, as a coolant, when one or other clutches 21, 22 is in use and the relative valve 26 or 27 opened. In normal use, valves 26, 27 are closed, a spring 63 is compressed, the piston 49, seated against a shoulder at the bottom of the chamber 44. closes a port 43 and the plug has opened a by-pass 58. All of the discharge from the pump 11 then feeds the jets 19 and all of the discharge from the pump 12 passes through the by-pass 32, the pump 12 thus being unloaded. With a clutch 21 or 22 in use, the pressure in pipes 23, 17 is lowered and the spring 63 forces the valve spindle 50 upwards. This closes the by-pass 58 and the pump 12 supplies the pipe 31. If the pressure above the plug 48 is abnormal, a spring 53 is compressed and the plug acts as a relief valve, allowing fluid to pass to the pipe 32. An additional relief valve 20 is provided.

Title: Improvements in and relating to electric signalling and indicating apparatus and the like
IPC: G08B7/06
Filed: 1928-06-20
Abstract: 319,600. Cowx, H. S. June 20, 1928. Non-seleclive audible and visible signalling systems.-In a signalling system of the type wherein, upon operation of a signalling switch. a bell and a lamp or other indicator are operated, and, upon release, the bell ceases ringing but the lamp &c. is maintained operated by a relay, the relay is provided with two or more windings arranged in parallel, one of the windings being connected in series with the lamp while the other windings serve to supplement the force of attraction of the first winding of the relay in order to ensure operation even when the resistance of the circuit including the first winding is unduly increased. As shown in Fig. 1, operation of a switch 12 rings a bell 15 and energizes a relay over a circuit including a winding 16 and indicator lamps 20. A second winding 27 is normally energized in a circuit including a pilot lamp, resistance, cholie, &c. 28, so that upon energization of the winding 16 the armature 17 is attracted to close a locking circuit for the relay through the armature, winding 16, and lamps 20. In this manner the lamps are maintained operated while the bell ceases ringing upon release of the switch 12. The lamps may be extinguished by switches 22, 21 arranged in the locking circuit, the switch 21 having an auxiliary contact 24 and a delay-acting device 26 adapted to maintain open the locking circuit and to cause operation of a bell 25, which may be situated at a remote point, for a predetermined time. A number of separate lamp circuits may be controlled by the switch 12, or a group of lamp circuits may be operated by a corresponding number of switches 12 which are, however, common to a single switch 21. In the modification shown in Fig. 2, the relay has two windings 34, 36 connected in parallel and two armatures 40, 41. Upon depression of the switch 32, the relay is energized in a circuit including the lamps 37. A bell 48 is operated in a circuit including the armature 41 and the armature 40 closes a locking circuit over a resistance 44 which reduces the holding current sufficiently to release the armature 41 and open the bell circuit when the switch 32 is released. Auxiliary signalling devices may be included in the circuits of the additional windings 27, 36, if desired. The systems may be operated from a d.c. or a.c. supply.

Abstract: 1425349 Recovery of metals and alumina from hydrodesulphurization catalysts UNION CARBIDE CORP 13 April 1973 [14 April 1972] 17853/73 Heading C1A A process for extracting alumina and at least one of the values selected from vanadium and molybdenum from a spent hydrodesulphurization catalyst comprises first calcining the spent catalyst to reduce its carbon content (e.g. at 725 C.) followed by roasting the calcined catalyst (at, e.g. between 525 C. and 925 C. for a time period between 1 and 4 hours), in the presence of sodium chloride in an amount at least stoichiometric for the reactions:  to substantially convert the vanadium and/or molybdenum values to the water soluble form; water leaching of the spent catalyst solubilizes the vanadium and/or molybdenum values while the alumina is retained in the residue and separated. The solution may be further treated with a tertiary amine to extract the metal values followed by stripping with, e.g. sodium carbonate solution and the vanadium may then be recovered by precipitation with ammonium sulphate at a pH of about 8, i.e. as ammonium metavanadate; the molybdenum remaining in the aqueous raffinate can be extracted with a tertiary amine and stripped with ammonia followed by acidification at 80 C. to precipitate ammonium tetramolybdate. The alumina may be recovered from the residue, as the hydroxide, by treatment with sodium hydroxide to dissolve the aluminium values followed by treating the filtrate containing sodium aluminate with acid to precipitate aluminium hydroxide; cobalt and nickel values which may be present in the spent catalyst collect in the residue obtained in the sodium hydroxide leaching.
