Title: Calculating instrument
Inventor: DELVES JAMES ALFRED HARRY
IPC: G06C1/00
Filed: 1968-02-23
Abstract: 1,235,923. Calculating instruments. BREES PLASTICS Ltd. 14 Feb., 1969 [23 Feb., 1968], No. 8868/68. Heading G4B. A calculating device, particularly for teaching arithmetic, comprises a member 1 having a longitudinal guideway 2, a slide 3 moving in said guideway, and a series of tablets 4 which are selectively inserted in said guideway. Each of the tablets 4 has a length proportional to the magnitude of a property for which the device is being used (e.g. money, length, number, area, volume). Selected tablets 4 are inserted in the lower open end of the guideway Z and slide 3 is brought into contact with the upper tablet, whereby graduations (S) (Fig. 2, not shown) on the slide, visible through a window 9 in the member 1, show the total value of all the tablets used. A narrowing of the guideway 2a, and ears 5 on the slide 3 prevent the latter being completely removed through the upper end of the device, and a window 6 in one face of the member allows markings N denoting the values of the tablets 4 to be seen. The tablets 4 may also be marked by a number of hollows (8), Fig. 4 (not shown), on their backs (corresponding to their values). They may also be colour coded.

Title: Heat-sealing
IPC: B65B9/20
Filed: 1957-03-18
Abstract: 849,222. Seaming. ARTHUR, J. March 17, 1958 [March 18, 1957], No. 8875/57. Class 42 (1). Two surfaces of a polyethylene terephthalate are welded together by heating them, while they are in contact, at a temperature which is below that at which embrittlement takes place (about 350‹ C.) and at or above the softening- point (i.e. minimum welding temperature) by directing a stream of heated gas on to the surfaces. A temperature between 200‹ and 300‹ C., and in particular 260‹ C., is stated to be satisfactory. As shown, a ribbon A of polyethylene terephthalate from a reel 11 is folded longitudinally at 13, 14 and the abutting edges are seamed together by a jet of heated nitrogen from a nozzle 17 to form a tube B. The nitrogen jet impinges on the edges as they protrude slightly from the jaws of a welding block 15. The jaws are cooled by water &c. supplied via pipes 25, 26, and their spacing is adjusted by means of a screw 21 so that the ribbon is just able to move freely. The nitrogen is heated to a controlled temperature by an electrically-heated jacket 20. Extraction rollers 16 maintain the ribbon under slight tension to prevent contraction of the ribbon edges. The tube may be subsequently divided into sachets, the ends of which are sealed by a further welding. Preferably the nitrogen is dry and oxygen-free. The material may be preliminarily heat-treated to avoid contraction during welding.

Abstract: 1470950 Desulphurizing off-gases SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 8 March 1976 09194/76 Addition to 1356289 Heading C1A In a process in which H 2 S-containing gas is fed to a Claus plant, the off-gases from which are passed together with H 2 - and/or co-containing gas at above 175‹ C. over a sulphided Group VI and/or VIII metal catalyst on an oxide carrier, whereafter the reduced off-gases are absorbed in a liquid which is then regenerated to liberate an H 2 S-rich gas which is recycled to a Claus plant, gases not absorbed being discharged to atmosphere, the modification whereby, if the initial H 2 S-containing gas comprises above 20 vol. per cent CO 2 , at least part of the gas by-passes the Claus plant and is contacted directly with the liquid absorbent. In the Figure, H 2 S- and CO 2 -containing gas is obtained at 4 from absorption/regeneration unit 2 supplied with products of partial combustion. Part of the gas flows through Claus plant 7, and catalytic reactor 12, where H 2  or CO is fed in at 13, to selective absorption/regeneration unit 16. Off-gases (CO 2  and N 2 ) are discharged at 17 to incinerator 18 to remove traces of H 2 S. Regenerated H 2 S-rich gas is recycled via line 20 to Claus plant 7. A further part of the gas in 4 (e.g. 40-70%) by-passes the Claus plant and flows in 5 directly to absorption/regeneration unit 16. This gas may be subjected to an absorption process selective for CO 2 . Unit 16 is suitably a column containing less than 20 trays in which gas/liquid flow is countercurrent, the gas from line 5 being introduced at a point further from the absorbent inlet than the gas from reactor 12. The absorbent may be an alkanolamine having a tert. -substituted N atom.

Smoke, consuming.-Smoke is mixed with town or producer gas and conducted to suitable burners where it is burnt like ordinary illuminating-gas. Air, oil, or pulverulent fuel may be added to the mixture. The smoke may be conveyed from the source through a conduit a, Fig. 1, which may be provided with a fan b, and gas is injected into the conduit from a pipe c, the mixture being conveyed to burner. The nozzle d may be surrounded by a pipe h for conveying air to the burning mixture. Pulverulent fuel may be fed to the nozzle d from a hopper. In the modified form of apparatus shown in Fig. 5, the gas pipe i is arranged within the smoke pipe a, and discharges gas through nozzles to burn with the smoke at orifices k. In the modification shown in Fig. 7, smoke and combustible gas or sprayed fluid from the pipe a and air from the pipe h enter a chamber o where combustion takes place with coal dust fed from a hopper m. The gases generated pass into a chamber p<1> supplied with air from a pipe h<1> and thence to a service pipe q into which a further supply of air, gas or fluid is injected by the pipe r. Fig. 8 shows a further modification in which the smoke, gas and air from pipes a, c and h respectively are injected tangentially into a chamber u, coal dust or the like being fed from a hopper b<1> into the path of the flaming mixture. A pipe v at the top of the chamber allows for the escape of the products.
