Title: Improvements in or relating to fastenings and hinges for expanding trunks or the like
IPC: A45C7/00
Filed: 1926-12-11
Abstract: 287,211. Kennedy, E. N. Dec. 11, 1926. Hasp fastenings.-In an expanding receptacle such as a suitcase of the type having provision for the control of relative telescopic movement of the two hinged parts and having one or more of the means for controlling such movement operable when the receptacle is closed and governed by a device operable from the outside of the receptacle, the mechanism of the governing device and/or one of the means governed thereby is concealed substantially within the confines of the receptacle at all degrees of its expansion, as also may be the hinge or hinges. As shown, the racks 17 secured to the telescopic parts 11, 12 of the suitcase, and the detents 13, 14 which engage with the racks, comprise the means for controlling the relative movements of the members 11, 12, the device for governing the controlling means comprising the slidable bar 20, connected to the detents, the lock 22 and its member 21, and a member 24 connecting sets of bars 20. The racks and the detents operable and controlled by the lock constitute telescopic fastenings or hinges for the two parts of the suitcase. As shown, a rack 17 is mounted on one or more of the inside corners of the outer portions 11 of the suitcase, and it is adapted to be engaged by detents 13, 14 which respectively allow movement in one direction or in neither direction. The sets of detents at opposite sides of the case are pivotally mounted on a plate 18 and are connected by pins 23 to an operating bar 20 that is operable by means of a slidable member 21 of the lock 22. The front and rear bars 20 are connected by a rod 24. To retract the detents from the rocks, the nozzle 27 of the lock is first rotated in an anti-clockwise direction until its pins 28 move into the dotted line position to slide the front bar 20 slightly to the left and so disengage the detents 14 from the racks 17; the nozzle 27 is then moved bodily to the left against a spring, the further movement of the bar 20 is affected disengaging all of the detents 13. When the nozzle 27 is in the latter position, the hasp 26 moves outwardly under its spring and serves to retain the nozzle 27. The detents 13. have a knib 13<a> that is rounded on one edge to ' allow of a one-way telescopic movement with the rack. The outer part 11 of the case is connected by hinges with the pivot 29 positioned at the lower edge of the outer wall of the case, the outer face of the inner part 12 of the case having a guide 30 through which one limb of the hinge is adapted to slide.

Patent GB-211923-A (GB)
Title: Improvements in or relating to the manufacture of cattle feeding cakes and oil
IPC: A23K1/14
Filed: 1922-11-20
Abstract: In the manufacture of compound cattle-feeding cakes involving the crushing of seeds and the extraction of oil by hydraulic pressure, molasses, spices, or other flavouring materials are mixed with the other ingredients before the extraction of the oil and formation of the cakes.  The flavouring materials may be added at one or more of the stages in the milling or cooking processes. They may be added before the first rolling of the seeds, or during the first or second rolling, or in a separate mixing machine situated between the rollers and the cooking kettles, or in the p  kettles themselves.  The flavouring material may be treacle or glucose, with or without water, or sugar-yielding natural products, such as sugar-cane or sugar-beet. The materials to be employed in making the cakes may consist of cotton seeds, linseed, soya beans, palm kernels, copra, sesame seeds, ground nuts, farinaceous materials, &c.  Ground, crushed, or broken cake may be mixed with the seeds to be crushed.  In manufacturing sweetened palm-kernel cakes and palm kernel oil, liquid molasses may be added between the first and second passages of the material through the crushing rollers and in quantities up to the equivalent of 50 per cent of the finished cakes.  It is stated that oils freer from non-oleaginous impurities are obtained, and that the expulsion of the oil is more efficient in consequence of the presence of crystalloidal or semi-crystalloidal non-electrolytes of the sugar and sugar related groups of compounds.  Specifications 4961/79, 9667/92, 19309/94 and 24288/04, [all in Class 5, Agricultural appliances, Farmyard &c.], and 4515/08 are referred to.

Title: Improvements in sulphur recovery
IPC: C01B17/06
Filed: 1947-12-01
Abstract: Sulphur is recovered from iron sulphide-bearing material by subjecting it to an oxidizing treatment to form (1) sulphur dioxide, (2) a solid product containing as iron sulphide about two-thirds of the sulphur of the sulphide-bearing material, treating the solid product in finely divided form with acid to produce hydrogen sulphide, and reacting the hydrogen sulphide and sulphur dioxide to produce elemental sulphur.  The sulphide material may either be roasted and the product smelted to produce a matte, or be smelted directly under oxidizing conditions to produce a matte; the smelting being carried out either with metallic iron or with iron oxide and coke.  The finely divided matte may be treated countercurrent with aqueous sulphuric acid at 50-70 DEG  C. to produce (1) hydrogen sulphide, (2) a solid product containing sulphides of cobalt, copper, gold, nickel, platinum, silver or zinc originally present in the sulphide material, (3) a solution of ferrous sulphate.  Part of the zinc may be recovered as zinc sulphate by cry tallization at an intermediate stage.  The hydrogen sulphide and sulphur dioxide are reacted in contact with an aqueous solution of an alkali metal compound, such as sodium carbonate, sulphite, hydroxide, or sulphate, by bubbling the gases separately or simultaneously through a column of solution.

Abstract: 1,004,864. Centrifugal pumps. G. NEIDL. Sept. 5, 1961 [Sept. 6, 1960; Oct. 21, 1960; Aug. 3, 1961], No. 31818/61. Heading F1C: [Also in Divisions B2 and B3] In a rotary pump comprising an impeller mounted in an inclined position on a shaft as claimed in Specification 848,757, a screw conveyer is used to feed material to the pump. Fig. 1 shows a pump in which the material is fed to the inclined-disc impeller 150 by way of a conveyer belt 209, a hopper 155 and a screw conveyer 153. The material is discharged through a tangential duct 160. The impeller 150 and the screw 154 are independently driven through infinitely variable gears 151 and 158 respectively. The conveyer belt may be replaced by a bucket conveyer or a further screw conveyer. Instead of being cylindrical as shown, the screw and its casing may be of conical form, tapering in the direction of feed. The casing of the inclineddisc pump may be of spherical or elliptical form. Fig. 6 shows three pumps connected in series, the first pump being fed through a hopper 189. The screws 190 are independently driven but the inclined-disc impellers are driven together through chain or toothed gearing 200, impeller 193 being 180 degrees out of phase with impellers 191, 192. When this phase relationship is not required, the impellers can be non- positively driven through belts. The axes of the pumps may be vertical, as shown, or horizontal. The pumps may be used for the treatment of cellulose, cellulose pulp, waste paper, rags or the like. A filter may be provided at the outlet of one or more of the pumps to prevent the passage of lumps. For the purpose of comminuting the material, the inclined-disc impeller may be provided with peripheral teeth cooperating with grooves on the inner periphery of the casing, as described in Specification 879,546. The teeth may be cut in a lathe by means of a tool 258, Fig. 15, the impeller disc 248 being mounted between centres 256, 257 by means of hubs 249, 252. After a set of cuts has been made the impeller disc 248 is turned through 90 degrees relative to the hubs 249, 252 and a further set of cuts is made with the tool 258. These cuts cross the original cuts, whereby the pyramidal tooth form shown in Fig. 14 is generated. The teeth alternate in two rows, each tooth having a triangular face 243 lying in the plane of one or the other of the two faces of the impeller disc. The two other triangular faces of each tooth have a common edge 247 running from the apex of the pyramid to the opposite face of the impeller disc. Further sets of cuts may be made, using hubs giving different angles of inclination from the angle a shown in Fig. 15. In an alternative set-up, the impeller disc is mounted on a single hub carried by a chuck.

Abstract: 1,100,100. Weighing apparatus. C. JOHNSON. July 15, 1966 [July 19, 1965], No. 31906/66. Headings G1N and G1W. In a modification of the force measuring or weighing apparatus described in Specifications 947, 120 and 829, 252, a plurality of flexure spring-members are operatively connected between a cantilever load receiving platform, supported on a pedestal fixed to base by a flexure pivot, and the said base, in order to resist pivotal displacement of the platform by a force applied thereto, said springs being connected in series between the base and platform. The platform may support a bearing for a conveyer belt roller whereby the load on the conveyer is sensed. The free end of the cantilevered platform 28, Figs.2 and 5 is coupled to a differential transformer armature core 74 which is movable within a coil unit 110. Movement of the armature 74, because of thermal expansion of the components coupling it to the platform, is taken care of by suitable choice of materials of the coupling components (see Specification 947, 120) and by adjustment of screws 106, 108. In Fig. 2 the platform 28 is hinged or pivoted to the base 22 by a flexure plate 32. Located between the base and platform and parallel thereto are three parallel flat leaf springs in an assembly 134. The springs lie in one horizontal plane and two outer springs (138), (140) Fig. 3 (not shown) are fixed in cantilever fashion to the base 22 while the middle spring 136 is similarly fixed to the platform 28. The free ends of the springs are clamped together by a clamp 146. The load range of the apparatus is adjustable (e.g. from 100 to 2, 000 lbs) by moving the clamp to selected positions along springs 136, 138, 140 to alter their effective lengths and stiffness. Alternatively the springs are of circular cross-section, or the two outer springs may lie in a plane spaced from that of the inner spring Figs.14 and 15 (not shown).
