Abstract: 1371506 Propellants; cooling gases SOC NATIONALE des POUDRES et EXPLOSIFS 30 Nov 1971 [11 Dec 1970] 55602/71 Headings F3A and F4K [Also in Division F1] A gas generator supplying cooled combustion gases, e.g. to an inflatable vehicle safety bag, comprises a solid propellant 10 which when fired directs gases through ports 17 into a mixing chamber 16 into which a vaporizable liquid is also injected through ports 18 from reservoir 6, the liquid cooling the gases and oxidizing noxious constituents. The gases then flow through ports 9 into chamber 7 into which further liquid from reservoir 6 is injected through ports 8 in partition 5. The cooled and purified gases exhaust through a diffuser 19. The liquid may be water with the addition of an oxidizing compound such as hydrogen peroxide, potassium permanganate or potassium nitrate. The liquid is expelled from reservoir 6 by the action of the combustion gases on piston 15. The propellant 10 may be a double base powder of nitroglycerine and nitrocellulose in the form of hollow strands, a powder of lamellar or corrugated cardboard, or a composite powder of potassium perchlorate and polyurethane. Propellant 10 is supported adjacent igniter 13 by an annular plastics sleeve 11.

Abstract: 1312362 Selective printing TRIUMPH WERKE NURNBERG AG 25 Nov 1970 [27 Dec 1969] 56051/70 Heading B6F Mechanical combination selection device; interlocks between keys and between interposers.-A continuously rotating filter shaft 21 co-operates with a selected interposer 14 to tilt the coding bails 19 and also tilt a locking rail 24 against the bias of a bi-stable spring 26 so that it abuts a stop 28. In this position of the locking rail 24 (Fig. 2), the next selected interposer 14 is not allowed to tilt so that its dog 20 cannot engage the filter shaft, due to the rail 24 engaging a nose piece 23. However, when the previous cycle is completed, a solenoid 29 is energized to tilt the locking rail 24 back against stop 27, so that the next selected interposer is allowed to tilt and cooperate with the filter shaft 21. Actuation of a key lever 1 causes a finger 6 to bear downwardly on a release lever 5. In consequence lever 5 pivots about rod 8 so that a nose-piece 11 penetrates two adjacent elements of a locking means 12 to prevent actuation of another key lever. Pivoting of a release lever 5 causes its lug 13 to slide from the rear end 14a of an interposer 14, thereby allowing the interposer to pivot about rod 16 under the influence of a spring 17. Subsequent longitudinal motion of the selected interposer 14 causes its release lever 5 (which now abuts the end of the interposer, Fig. 2) to move upwardly due to the fact that the pivot rod 8 engages in an elongate hole 7 arranged obliquely. This releases the lever 5 from the locking means 12, so that the next key lever can be actuated. However, the interposer 14 selected by such key lever actuation will not pivot until the locking rail 24 is returned to stop 27, as described above.

In longitudinally seam welding strips 9, 10, the strips as they are fed towards a welding head 7 are held in alignment by clamps 13 movable with the strips. As the first clamp 13 approaches the welding head it is released and moved back towards the second clamp 13 and reclamped, and then the second clamp 13 is similarly retracted and so on. Each clamp 13, comprising clamping members 17 on arms 14, 15 connected by a pivot 16, is first lightly clamped on the strips 9, 10 by a pneumatic piston and cylinder device 20. A second pneumatic device 18 then presses the aligned strips 9, 10 against an adjustable stop 19 and the first device 20 then applies full clamping pressure. The strips, which may be continuous bands passing over a roller 11 and a tensioning roller 12, at the welding station pass over a grooved backing roll 4 mounted on a transversely movable frame 3 carrying an inert gas shielded welding head 7. The clamps are wholly supported by the strips 9, 10 or are mounted on rails. In the latter case, they may be automatically controlled. The frame 3 may be mounted on rollers 2 or suspended by a parallelogram linkage. The strips 9, 10 may engage guides 5 on the backing roll 4 to locate the frame 3.

A keyboard 8, 9 mounted on the vehicle is operated to indicate a desired stopping position and this value is applied to a subtractor 12 together with the count at either counter 6 or 7 via gates 10 depending upon whether the setting at 8 is for an even-or an odd-numbered bay, since counter 6 is designed to count through the even nos. 2, 4, 6 ... and counter 7 the odd numbers 1, 3, 5 ... only, for in a typical warehouse, bay no. 2n will be opposite bay no.(2 n+1). The count at either 6 or 7 is also displayed at 11. When the number at 12 is less than a predetermined value, a lamp 13 will be illuminated to tell the vehicle driver to slow down. When the vehicle is within a very short distance of the required stopping point, a further logic circuit 14 is activated, and depending upon the sense of the sequence of activation of the detectors, illuminates one of the two lamps 15, 16 to tell the driver to move in one of the two directions. The correct position is reached when the detectors are simultaneously activated. In correct counting either due to hunting or a small reversal of direction during travel is prevented by the circuits 5, 14.

The reduction step is effected at 500 to 800 C. at atmospheric pressure, the fluidizing medium is a gas comprising hydrogen and the bed material is synthetic rutile. The liquid reagent sidestream contains salts giving solid reduction products which are deposited on the bed material, the bed material being continually withdrawn, leached to extract soluble solids therefrom and then returned to the bed. The withdrawn bed material is leached with the liquid reagent sidestream to produce a slurry of bed material and reagent and a liquid phase enriched in the soluble solids, the slurry being fed to the bed and a portion of the liquid phase being recycled to the circulating liquid reagent of the gas purification process. A sidestream of the liquid reagent of a first gas purification stage is used to leach the withdrawn bed material and to form the slurry, and a sidestream of the liquid reagent of a second gas purification stage may be added to the slurry for admission therewith to the fluidized bed. Portions of withdrawn bed material may be respectively leached with sidestreams of liquid reagents of individual gas purification stages to form individual slurry portions and associated liquid phases, portions of the respective liquid phases being recycled to the circulating reagents from which the individual sidestreams derived.
