Title: Molecular models
IPC: G09B23/26
Filed: 1975-03-04
Abstract: 1502637 Structural joints A DREIDING 4 March 1975 [5 March 1974] 8847/75 Heading F2M [Also in Divisions E2 and G5] Relates to stereochemical models of molecules made up from a number of structural elements 20 each representing a polyvalent atom and/or atom group and for this purpose having two or more connector arms 22a, 22b, 22c representing the valencies of an atom or atom group. In order to allow quick coupling and release of each arm from an arm of an adjacent structural element or, where as shown the arms are flexible, from another arm of the same element, each arm has at its free end a coupling element 24 adapted to mate directly with an identical coupling element on any other arm of the or another structural element. Preferably, in addition, each arm is rotatable relative to a central body 21 of the element by a coupling 23 consisting of a spigot 29 which fits in a socket 28 of the body 21 and is grooved to receive a spring retaining clip 31, 32. The base of the groove in the spigot may have a number of flats (42, Fig. 3A or 43, Fig. 3B, not shown) to define preferred rotational positions of the spigot within the socket. In one form the coupling elements 24 each consist of an insert 36, Fig. 4, which is pushed into a closely coiled spring 26 constituting one of the arms, e.g. arm 22a, the insert being formed to provide a projecting spigot 37 of semi-circular section having a rib 39 and a groove 40, the insert being pushed into the coiled spring such that a complementary socket 38 is formed. The resilience of the spring 26 allows the spigot of a similar coupling element on another arm 22d to be pushed into the socket 38 so that its rib 39 snaps into the groove 40 while rib 39 of the spigot 37 snaps into the groove 40 of the other spigot. In the modification of Fig. 7 the rib 39 is omitted and groove 40 is replaced by a circumferential groove 50 which is engaged by an end portion 49 of the coiled spring of the other arm 22d. A leaf spring (58, Fig. 9, not shown) may replace the portion 49. A coupling element 24 incorporating a rotational coupling similar to coupling 23 may be used (Fig. 10, not shown). In Fig. 15 each coupling element has a pair of hooks 89, in addition to a spigot and socket of semicircular section, so that the coupling is locked by bayonet action. In Fig. 16 a magnetic coupling is used.

Abstract: 418,175. Respirators. DEHAN, G. DOLNE-, 37, Rue des Augustins, Liege, Belgium. March 23, 1934, No. 9129. [Class 81 (ii).] In a closed-circuit respirator employing regenerating and oxygen-evolving chemicals the chemicals are contained in a canister 3 detachably secured to a chamber 1, carrying the breathing hoses and a breathing bag 12, by the provision of sockets in the canister engaged by spigot tubes 5, 6, on the chamber. The canister is further held against a wooden frame 26, extending beneath and along one side thereof and attached to chamber 1, by a band 27 and a press stud fastening 28. The chamber 1 is of brass or copper, has a cover 2, and has a conduit 7 communicating with the exhaling hose 9 and the spigot 5. The spigot 6 is closed by a valve 13 having a spring 14 ; this valve is held open by a rod 29 in the canister and seals the chamber on removal thereof, the spring 14 being strong enough to prevent movement of the valve during inhalation. The inhaling hose opens directly into the chamber. The action of the chemicals, carried on gauze trays 4 within the canister, is initiated by a liquid such as a saline solution, enclosed in a sealed vessel 19 and released through perforations in the bottom thereof by removal of a strip 21 torn off by rotation, by a knob 24, of a spindle 23 connected by a wire 22 to the remote end of the strip. The released liquid falls as a shower on to asbestos, pumice, quick lime, porous baked earth &c., in a gauze covered tray 16, the water vapour so produced serving to excite the chemicals.

The points of the line 56 to which the switching elements 62 are connected are chosen so that the delay between the signal at the output N5 of ladder network 72 relative the input of the line 56 is identical no matter which of the switching elements 62 is energized. As described, leakage of signal through the switching elements when they are turned off is cancelled by feeding a controllable portion of the inverted R.F. signal via an R.F. line 51 and a turned-off F.E.T. 55, to be added to the signal from the ladder network at the input of an output buffer amplifier 42 (not shown). As described, Figs. 1 and 2 (not shown), a number of the attenuator circuits are connected in series in the input to the coherent pulse Doppler radar receiver of Specification 1,372,469, and the switching elements are controlled so that the attenuation is reduced as a fourth power of elapsed time by feeding appropriate digital signals from a read only memory (R.O.M.). Each switching circuit includes shunt 64 and series 62 switching elements.

Title: Process for the production of alumina
IPC: C01F7/26
Filed: 1960-03-18
Abstract: In the production of alumina a silico-aluminous ore is roasted with ammonium sulphate, the roasted ore is lixiviated, the resulting solution is decanted and filtered, aluminium ammonium sulphate obtained from the solution is purified by removing iron and titanium salts and silica, and alumina is precipitated from a solution of the purified aluminium ammonium sulphate by means of ammonium hydroxide or sulphide.  The solution resulting from lixiviation is cooled with agitation, after the addition of further ammonium sulphate if required, to crystallize out the aluminium ammonium sulphate leaving most of the iron and titanium impurities in solution.  The crystals are redissolved in water and ammonium ferrocyanide and copper sulphate added to precipitate iron, which is filtered off, and the filtrate cooled to crystallize the aluminium ammonium sulphate.  The crystals are melted in their water of crystallization, zinc sulphate is added to precipitate any remaining silica, the melt is separated from insoluble residue and reacted with ammonium hydroxide solution or ammonium sulphide, causing aluminium hydroxide to precipitate, and finally the precipitate is calcined.  An example is given. Specification 737,904 is referred to.
