Title: Electric circuit interrupters
IPC: H01H33/86
Filed: 1962-04-04
Abstract: 960,972. Gas-blast switches. WESTINGHOUSE ELECTRIC CORPORATION. April 4, 1962 [April 11, 1961], No. 12873/62. Heading H2B. A gas-blast circuit interrupter comprises an earthed tank 2, a pair of terminal bushings 5, 6, a support bushing 14, an arc interrupting assembly carried by one of the terminal bushings 6 and the support bushing 14, and an isolating switch 16 between the support bushing 14 and the other terminal bushing 5. In the arrangement shown, the interrupting assembly comprises a plurality of fixed nozzle contacts 55 and of movable contacts 52, the latter comprising circumferentially-disposed flexible contact fingers carried by rods 44 which are interconnected by a ladder-like structure (not shown). To open the interrupter, mechanism (not shown) connected to an operating rod 29, is released so that high pressure gas within the casing 74 and acting on a bellows 37 causes the opening movement of the movable contacts 52 and the isolating switch contact 18. As each movable contact 52 moves, a member 72 on the end of the rod 44 carrying the next contact 52 moves a lever 68 to open an exhaust blast valve 59, so that gas flows from the space 80 through the nozzle contact 55, a cooling screen and the valve 59 to the tank 2. After a predetermined opening travel of the contacts 52, each member 72 moves past the lever 68 so that each blast valve 59 is reclosed by its spring 62 to shut off the gas-blast. The movable contact 18 of the isolating switch then separates from the fixed contact 19. The arc-extinguishing gas may be sulphur-hexafluoride, the interrupter being of the dual pressure re-circulating gas-blast type. Voltage dividing resistors 96 and current transformers 97 may be provided. Specification 885,932 is referred to.

Title: Improvements in or relating to hub cap distance registers for vehicles
IPC: G01C22/00
Filed: 1929-04-25
Abstract: 332,640. Ripaults, Ltd., and Harley, C. E. April 25, 1929. Odometers.-A hub cap odometer for vehicles comprises a drive plate c extending across the whole or greater part of the area of the interior of the hub cap b so as to prevent the iningress of lubricant from the lubricant chamber d to the chamber containing the odometer mechanism a. The drive plate c is attached directly or indirectly through the ball race housing g of the odometer to the end of the odometer driving spindle so that the spindle is enclosed in the hub cap b by the drive plate and does not extend into the lubricant chamber d. When lubricant is forced into the chamber d the drive plate c is forced against the seating e thus cutting off the lubricant chamber from the odometer chamber. The drive plate c is provided with two projections c<1> at right-angles thereto having slots c<2> in which engage pins or projections f<1> upon a further drive plate f which is spring controlled and which is provided with projections f<2> adapted to engage the end of the stationary axle or some other fixed part so that the hub cap rotates relatively to the drive plate c and is caused to operate the odometer. The drive plate c may have a certain amount of flexibility and may be provided with annular grooves for this purpose. The invention can be applied to the alternative form of odometer in which the spindle rotates and the odometer is stationary.

Title: Process for the preparation of a methane-rich gas
IPC: C10K3/00
Filed: 1973-03-19
Abstract: 1458666 Methane-rich gas SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 15 March 1974 [19 March 1973] 13114/73 Heading C5E A process for preparing a methane-rich gas comprises the steps of (a) partial combusting a fuel, e.g. fuel oil, with an oxygen-containing gas, (b) injecting a cool hydrogen-containing gas into the hot gas produced, and (c) injecting a normally-liquid hydrocarbon fraction into the cooled gas in a carburetter. Step (b) can be carried out using a volume ratio of cool gas to hot gas between 1 : 10 and 5 : 1 to cool the hot gas to 650-1100 C. so that cracking of the injected hydrocarbon fraction either to olefins or to hydrogen and carbon is substantially avoided. The cool hydrogen-containing gas can be prepared by cooling a portion of the hot gas, e.g. to 175-600 C., and subjecting it to a catalytic CO-shift reaction followed by removal of CO 2 , alternatively extraneous sources of hydrogen, such as water gas, producer gas, tail gas or refinery gas can be used. A small amount of steam can also be injected into the hot gas. The hydrocarbon fraction injected in step (c) can be gasoline, kerosine or other distillate boiling below 350 C. The product from step (c), which in the example contains 23 volume per cent H 2 , 49% CH 4 , 25À6% CO and 2À4% CO 2 +N 2 + aromatics, can be subjected to catalytic methanation.

Title: A method of combining reinforcing fibres and liquid binding agents to produce pre-determined shapes
Filed: 1957-04-25
Abstract: Reinforcing fibres and a liquid binding agent, e.g. a polyester resin, are moulded into a predetermined shape in a mould assembly comprising two parts adapted to be closed together to form a moulding cavity, by first placing the fibres in one of the two parts, then placing the other part in contact with the fibres, introducing the liquid binding agent, and applying pressure to the mould parts to compress the fibres and to disperse the liquid binding agent throughout the fibres.  The examples describe the moulding of a dished plate and of an open box using as the reinforcement a glass fibre mat sewn to cellulose scrim, and as binding agent a styrenated polyester resin containing curing agents.

Abstract: 1,180,836. Stabilization of epoxides. ARGUS CHEMICAL CORP. 21 March, 1967 [4 April, 1966], No. 13193/67. Heading C2C. [Also in Division C3] Liquid epoxide compositions having improved resistance to discoloration and gelation and not curable by heating to 350‹ F., consist essentially of a liquid epoxide, containing only internal epoxy group and having a tendency to discolour and/or gel, and a stabilizing amount, insufficient to cure or polymerize the epoxide, of at least one organic phosphite ester containing at least two organic groups of 1-30 carbon atoms linked through oxygen to each phosphorus atom. The term "consisting essentially of" is defined as excluding from the compositions polyvinyl chloride resins and stabilizers for such resins, except the present phosphites. The compositions may include other inert diluents and solvents. Many epoxides which are stabilized by the organic phosphites are listed, in particular, epoxidized natural oils, epoxidized synthetic mono- and polyesters and olefins. A large number of suitable phosphites are named and fall with the general formula wherein R 1  is an organic group or hydrogen and R 2  and R 3  are organic groups. The radicals R are preferably aliphatic but may include additional phosphite groups or 2 or all of the radicals R may be joined to form a heterocyclic ring including the phosphite group. The amount of phosphite used is generally in the range 0À01-10% by wt. of epoxide, preferably 0À05-3%. Examples describe compositions based on epoxidized oils, particularly epoxidized soybean oil, and synthetic esters.

Abstract: 132,649. McCoy, T. J. Oct. 11, 1918. Drawing.-Relates to apparatus for making sheet glass by causing molten metal to flow in sheet form from the melting-tank on to a conveyer. In the arrangement shown in Fig. 4, the metal 22 flows from the tank 20 over a stone 24, descends vertically, and is received on a series of tablets 26 moved forward by an endless chain 31. The tablets carry lateral pins which slide on guides 28, and deliver the sheet to lifters 44, from which it passes over a roller. After passing the lifters, the tablets are moved downwards by rotary disks 116, 118, the pins sliding in guides, and are transferred to an endless chain 30, which returns the tablets to the front of the tank. The tablets are raised by rotary disks 112, 114 coacting with guides, and are returned to the chain 31, by which they are again carried forward. The tablets are formed with upstanding sides and carry transverse blades at their rear edges, so that the glass sheet is severed as it passes under a roller 51. The tank is provided with an extension chamber 74 fitted with a cap stone 65, which can be adjusted vertically and angularly by screwed rods 66, and a front stone 68 vertically adjustable by a rod 69. A gas-burner 73 is arranged in the chamber 74, and a water-duct 76 is disposed behind the vertical part of the glass sheet. Pivoted guides and retaining-plates are provided to ensure that the pins on the tablets take the required paths. Specification 117,194 is referred to.
