Title: An improvement relating to means for adjusting the height of tennis and like nets
IPC: A63B61/04
Filed: 1928-12-04
Abstract: 322,644. Hirst, R. R., and Hirst, A. Dec. 4, 1928. Addition to 265,803. Ground anchors. - The anchorage a for the height-adjusting means h of a tennis net claimed in the parent Specification is modified to prevent accidental detachment of the height-adjusting means by providing the upper surface of the upper piston b, or of the block, with a pivoted hook member e, a fixed vertical projection f and a spring plunger g. To insert the eye h<1> of the height-adjusting means the hook member e is rocked backwardly against the pressure of the spring plunger to provide a gap between the hook member and the projection f.

Abstract: 1,184,605. Welding by pressure. RUBERY, OWEN & CO. Ltd. 4 Nov., 1968 [3 Aug., 1967], No. 35703/67. Heading B3R. A mounting for a welding gun comprises a fitting 15 to which the gun is secured by readily removable means 13 and which is secured to a stationary part 16 by a swivelling joint adapted to be locked in adjusted position by means 21 which are only accessible on removal or displacement of the gun. The fluid pressure cylinder 10 of the spot welding gun has at its upper end a lug 11 with an open ended slot 12 through which pass bolts 13, 13 into an offset part 14 of the fitting 15. A boss 17 on the fitting has a part-spherical upper surface 18 co-operating with a frusto-conical surface 25 on a block 26 fitting against the stationary part 16 and a bolt 21 carrying a washer 25 having a part-spherical surface 24 co-operating with a frusto-conical surface in a recess 22 of the fitting passes through a frustoconical opening 19 in the boss through a hole in the block 26 and into the stationary part 16. With the bolt loose the fitting is angularly adjusted to move the gun up to 10 degrees from its central position, the bolt being exposed on loosening the bolts 13, 13, and removing or pivoting the gun. The frusto-conical surfaces in the block 26 and recess may be replaced by part-spherical surfaces and in a modification a serrated washer is interposed between the heads of the bolts and the lug 11 to prevent slackness during operation. The mounting may be used in multiple spot welding assemblies.

Patent GB-787936-A (GB)
Title: Manufacture of chlorinated, aliphatic hydrocarbons from cyclic organic compounds
IPC: C07C17/361
Filed: 1955-12-15
Abstract: Chlorinated aliphatic hydrocarbons having 1-4 carbon atoms in the molecule are manufactured by reacting a cyclic organic compound with chlorine at a pressure at least atmospheric and a temperature above 100 DEG  C. until at least two ring linkages in each ring of the cyclic organic compound are ruptured.  The reaction may be catalysed by Lewis acids (e.g. FeCl3 (which may also act as a source of chlorine), AlCl3, BiCl3, SbCl3, ZnCl2, NiCl2, AsCl3, SnCl4, H2SO4 or BF3) or other catalysts of the heterogeneous type (e.g. BaCl2 or Na2SO4, e.g. on carbon), which enable the process to be carried out at relatively low temperatures, the use of particularly effective catalysts such as FeCl3 or AlCl3 facilitating working in the liquid phase.  In the absence of a catalyst the latter requires temperatures above 400 DEG  C. (e.g. in the range 400-800 DEG  C., preferably 425-550 DEG  C.) and pressures above 20 atmospheres. The reaction may also be effected in the vapour phase at 400-1200 DEG  C., advantageously at atmospheric pressure.  Specified started materials, some of which are used in examples illustrating a variety of reaction conditions, are hexachlorocyclohexane, mono-, di-, tri- and hexa-chlorobenzene, decachlorocyclohexene, dodecachlorocyclohexane (which may also act as a partial source of chlorine), alkylbenzenes (e.g. toluene, xylenes, pseudo-cumene, isodurene, ethylbenzene and propylbenzene) and their addition and substitution chlorination products, monohydroxybenzenes (e.g. phenol, cresols and pentachlorophenol), polyhydroxybenzenes (e.g. catechol, resorcinol and pyrogallol), phthalic acid and anhydride and their chloro-derivatives (e.g. tetrachlorophthalic anhydride), nitrobenzene, dinitrobenzenes, chlorinated nitrobenzenes (e.g. 3 : 4-dichloronitrobenzene), diphenyl, chlorinated diphenyls, benzophenone, lower alkyl derivatives of the last three, naphthalene, naphthols, mono- and poly-alkylnaphthalenes, indene, phenanthrene, anthracene, pyrene, chrysene, and heterocyclic compounds containing a preponderance of carbon atoms in the ring structure (e.g. o-phenanthroline, pyridine, a - and b -picoline, quinoline, indole, acridine, thiophene, pyrrole and furan), and also coal.  The main products obtained are carbon tetrachloride, hexachloroethane and perchloroethylene.

Title: Improvements in or relating to bonded articles containing silicon carbide and methods of making them
Filed: 1931-12-31
Abstract: Bonded articles containing silicon carbide are treated to remove free carbon and are then fired in a neutral atmosphere to avoid oxidation of the carbide.  For example, the articles are heated first in an oxidizing atmosphere to 600-900 DEG  C. in order to burn out the carbon, and subsequently in a neutral atmosphere to 1350 DEG  C. in order to vitrify the bond.  The tunnel kiln disclosed in Specification 319,840, [Class 51 (ii), Furnaces and kilns for applying &c.], is suitable for the operations.  Specification 9963/04, [Class 22, Cements &c.], also is referred to.

Abstract: 908,059. Reactor control rods. REYROLLE & CO., Ltd., A. Feb. 9, 1960 [Nov. 10, 1958], No. 36100/58. Class 39 (4). [Also in Group XXV] Control rods are suspended above passages in the core of a reactor by means of latches each operated through a direct mechanical connection by an associated mechanism responsive to abnormal conditions in the reactor. Fig. 2 shows the upper end 16 of a control rod and a disengaged latch comprising a tube 14 containing a plunger 10, balls 19, and a retaining sleeve 29. When the latch is engaged the sleeve is lifted clear of the balls by a ledge 30, the balls project under a shoulder 28, and plunger 10 falls to lock the balls in position. Any rapid fall in coolant pressure in the reactor makes a bellows 5 expand, which raises plunger 10 and releases the control rod from the latch. Fig. 5 shows a latch comprising a tube 31, a plunger 33, balls 42 and levers 45 carrying more balls in a cage; the latter balls engage a slot in the control rod wall. Lifting of the plunger allows the levers to move inward, the balls rolling on surfaces 50 and 52.

[Also in Divisions B4, B5 and B8] A device for automatically adjusting a speed controller 108, Fig. 27, in a bag making machine (see Division B5) includes forward and reverse drives operated by electrical clutches in response to signals preferably from photoelectric bag web scanning means. An input shaft 171, Fig. 23, of the adjuster 111 is driven at constant speed, conveniently by a belt 113 from the controller 108. The adjuster comprises a counter shaft 173, driven from the shaft 171 through gears 174, 175 and capable of driving a shaft 176 through a magnetic clutch 181, and an output shaft 172, directly driven by the shaft 171 through a clutch 180. The shaft 172 may also be driven by the shaft 176 by a chain 178, Fig. 25, so that the shaft 172 rotates in one direction or the other according to which clutch is energized by a switch 216 or 219, operated by the photo-electric means or by push buttons 212, 213, Fig. 26. The shaft 172, normally at rest, drives the adjusting shaft 109 of the controller. The period of rotation of the shaft 172 is limited by switches 189, 190 the latter being manually adjustable by rack means 193, 194, Fig. 23. The switches are operated by a block 186 traversing a screwed portion 187 of a shaft 183 driven from the shaft 172. The shaft 183 also carries a-cam 200 driven by it through a slip clutch 204 and limited in its rotation by a pin 201 and stops 202, 203. The cam operates one or other of switches 210, 211 so that when switch 216 or 219 is de-energized, the opposite clutch is actuated to produce a small reverse movement to centre the cam. This corrects for any delay, in hand operation, between the observing by an operator that the relative speeds are correct and his releasing buttons 212 or 213. Specification 933,897 is referred to.
