IPC: F41G3/00
Filed: 1920-07-02
Abstract: 146,317. Krupp Akt.-Ges., F. Dec. 16, 1915, [Convention date]. Sights. - Relates to guns having an independent line of sight as regards training, and consists in a construction in which the sighting - device, which is mounted on a part of the gun which partakes of the training movement of the barrel, is adjusted relatively to this part by an operating member which is so connected to the gun-training gear that, when the member is operated, the gun barrel and the sight rotate through the same angle but in opposite directions. In the construction shown, the sight J is mounted on a bracket B<3> carried by the gun cradle B, which turns with respect to the top carriage C about a pivot b<1>. The training-gear comprises a worm k<1>, carried by a hollow shaft K mounted on the top carriage C, engaging a toothed sector b<2> on the cradle. The worm is operated by differential gear k<2>, n<2>, q<2>, Fig. 4, actuated by either of the two hand-wheels m<1>, p<1>, Fig. 3, one of which, m<1>, is connected by a shaft N, bevel-gearing n<4>, r<1>, and a shaft T<2>, T<3> to mechanism for turning the sight relatively to the gun about a vertical pivot i<2>. The gears are so proportioned that when the hand-wheel, m<1> is operated the gun and sight are turned through equal and opposite angles, the direction of the sight line thus remaining fixed. When the hand-wheel p<1> is operated, both gun and sight turn together. Gun and sight elevating-gear of known construction is described. Specifications 18231/08 and 12753/11 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification in which the top carriage is made in two parts, the upper part being mounted so that it can be trained with respect to the lower part, while the gun-cradle can be trained with. respect to the upper part. The sight is mounted on the upper part of the top carriage. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in fasteners of the sliding clasp type
IPC: A44B19/04
Filed: 1937-07-01
Abstract: 478,490. Fastenings. RADREIFEN AKT.-GES., and URBAN, W. July 1, 1937, No. 18340. Convention date, March 13. [Class 44] A sliding - clasp fastener suitable for attaching a cloth or sheet to a rigid bar or plate such as for attaching automobile hoods, tent canvas, or furniture covers to a frame comprises a flexible strip 5 with a series of male members 3 thereon which are engaged with female members on a rigid strip or base, the male members being undercut at their leading edge 4. The female members may be formed by the intervals between undercut blocks on the rigid strip or by undercut recesses 8 in a bar 7. The male members are brought into engagement by means of a slider 10 moving in the direction of the arrow, Fig. 1, and are disengaged manually by pulling, the left-hand end in the reverse direction. An end fastening such as a press-button may be fitted. The slider has an upper flange 13 extending over the sheet or the like 1 to which the flexible strip 5 of the fastener is attached, and has internal flanges to form a guideway 14 for the male elements. The fastener shown in Fig. 11 has sickle-shape male elements 40 engaging similarly shaped grooves in cylindrical elements fixed on the rigid member. Figs. 13, 14 show a slider for use with curved-closure fastenings. Three frames 17, 18, 19 are connected by a laterally flexible strip 20. Outer strips 21, 22 forming the side walls of the channel 14 for the male elements are fixed only to one of the frames and can slide with respect to the other frames. Thus the slider can be deformed laterally to conform to the curvature of the fastening closure. Instead of the flexible strip 20 link connections may be used. In another form for curved closure fastenings the slider moves on the rigid member by only two hook connections, Fig. 17 (not shown). The other slope of the slider may have a guideway adapted for fastening the other edge of the sheet. The male members are of a harder material.

Abstract: 1509184 Hydrogen storage apparatus ASSOCIATED ENG Ltd 25 July 1975 [26 April 1974] 18485/74 Heading C1A A hydrogen storage apparatus comprises storage means 10 for storing metallic hydrides charged with hydrogen, a heat exchanger 12, 13 for heating the hydrides to evolve hydrogen gas, a gas path around which hydrogen gas can circulate and including the storage means, the heat exchanger and a duct 11, 14, 16 external of the storage means, a pump 15 for circulating gas around the path, and means (filter 18, valve 19, pipe 17, burner 20) whereby part of the circulated hydrogen may be withdrawn from the path. Preferred metallic hydrides are magnesium hydride and iron-titanium hydride. As shown in Fig. 2, container 10 contains a gas packed bed of particulate metal hydride up to a level 23, which in operation, forms a fluidized bed up to level 24. Above level 24 is a filter 25 permeable by hydrogen, but not by the particulate hydride. Duct 16 is connected within the container to a further filter 26, and connections 27 and 32 are made to the upper part of the container above and below filter 25 respectively, the latter enabling the container to be filled with fresh hydride; spent hydride is removed at 28. In operation, hydrogen gas with entrained particulate hydrides is circulated from the container, through duct 11, heat exchanger 12 and ducts 14,16 back to the container by pump 15. In the heat exchanger, the hydrides are heated by heat exchange with the hot fluid flowing through 13, and hydrogen is released in quantities dependent on the flow and/or temperature of fluid through side 13. Some hydrogen may be tapped off through filter 18, and valve 19 after use in burner 20, which may be a heater or heat engine. Spent hydride, being of higher density, accumulates in the lower part of container 10 and may be removed through 28. Container 10 may be removed and exchanged, or may be recharged either by circulating hydrogen therethrough, with coolant flowing through side 13 of the heat exchanger, or by passing hydrogen through the container via duct 16, connection 27 and valve 29.

Title: Improvements in or relating to the production of water soluble basic azo dyestuffs
IPC: C09B44/02
Filed: 1934-02-07
Abstract: Water-soluble basic azo dyes are made by coupling a diazo compound which contains no water solubility promoting radicle of acid character such as sulphonic or carboxyl groups but which may contain a quaternary ammonium group with an arylide of a b -keto carboxylic acid having a quaternary ammonium group in the arylide residue. Specified diazo components are the salts of trimethyl - (m - or p - aminophenyl-) ammonium and of the m<1>-or p<1>-aminobenzoyl derivatives of these or of o-, m-or paminobenzyl-pyridiniums, aminoazo compounds containing quaternary ammonium groups e.g. the salts of trimethyl - (p<1> - aminobenzene azo-phenyl-) ammonium and the aminoazo compounds from diazotized aromatic amino ammonium compounds and m-toluidine, a -naphthylamine or other middle component.  The dyestuffs are fast to light and are capable of fixing substantive and mordant dyestuffs of acid character on to cellulose fibres, e.g. cotton and viscose.  If the basic dye is applied first, it can also act as a mordant for non-substantive acid dyes or the dyeing can be after-treated with tanning agents, especially those of the pyrogallol or ellagene class.  The tanning agent may also be applied prior to the dyeing.  The dyeings may be after-treated with metal salts.  In examples the following yellow dyestuffs are described: (1) tetrazotized benzidine or (2) diazotized trimethyl-(p<1>-aminobenzoyl-m-aminophenyl-) ammonium methosulphate (obtained by condensing m-aminodimethylaniline with p-nitrobenzoylchloride, condensing with dimethyl sulphate and reducing) is coupled with trimethyl - p - acetoacetylaminophenylammonium methosulphate (obtained by condensing acetoacetic ester with p-aminodimethylaniline in xylol and the product obtained with dimethylsulphate).  The Specification as open to inspection under Sect. 91 refers to the use of the corresponding chloride as diazo component in p  example 2 above (the dyestuff being precipitated with calcium iodide) and to the corresponding secondary disazo dyes with m-toluidine and a -naphthylamine respectively as middle components.  This subject-matter does not appear in the Specification as accepted.
