Title: Improvements relating to ignition distributors for internal combustion engines
IPC: F02P5/10
Filed: 1960-06-30
Abstract: 908,882. Interrupters. GARBE, LAHMEYER & CO. A.G. June 30, 1960 [July 1, 1959; Sept. 9, 1959], No. 22895/60. Class 38 (5). An ignition distributer comprises a contactbreaker mounting plate supported in an angularly displaceable manner by at least one blade spring mounted on the distributer housing. The interrupter contacts 3, 4 (Fig. 1) are mounted on a plate 2 supported only by a blade spring 6 riveted between brackets 7, 12 on the distributer housing 1. The spring 6 is tensioned to give the plate 2 a counterclockwise bias about a point at the end of the bracket arm 12c. Vacuum in the carburetter inlet causes a diaphragm 8a to withdraw a rod 10 and hence rotate the plate 2 clockwise to advance the ignition timing. An adjusting spring 13 engaging a notch in the plate 2 is mounted on the bracket 12 which is deformable. By inserting a suitable tool through an aperture provided in the housing, the bracket 12 and spring 13 can be adjusted so as to pre-set the position of the plate 2. This spring 13 can instead be an adjustable coil spring. The bias of the mounting spring 6 may assist or oppose the diaphragm action. In an alternative embodiment (Fig. 7), the plate 202 is mounted symmetrically on three U-shaped blade springs 221. The vacuum-operated adjusting rod 210 acts on a line parallel to a diameter of the plate 202, which is adjusted by rotation about its centre. The springs 221 may be turned so that their limbs are vertical, the shorter limbs being mounted on the distributer housing.

Abstract: 1,026,784. Collapsible packing cases. DRYERS Ltd. Sept. 21, 1962 [June 24, 1961], No. 22932/61. Heading B8P. [Also in Division E2] A packing case has walls secured together in a readily dismantleable manner by a tongue- and-groove device, the parts of which fit together with a sliding action when the container is assembled. The tongue-and-groove device shown in Fig. 4 can be made by welding together metal plate sections 38, 39, 40 and 45, 43, 46 bent and/or cut to shape. In Fig. 4, the device is used for securing the lid 37, but the same device can be used when securing any two walls of the case 35, 36 and any number of such devices may be used to join any two walls. The lid may be completely secured in position by using a tongue and hasp which can then be padlocked. When the same device is used for lifting, Fig. 5 (not shown), metal strips 53, 48 are secured to the case and provided with lifting rings 54.

Abstract: 786,810. Electric measuring systems. SIEMENS & HALSKE GES. Aug. 11, 1955 [Aug. 12, 1954], No. 23169/55. Class 40 (1). Apparatus for determining the specific gravity of a gas by comparing the weight of a column 1 of the gas with that of a column 3 of equal length containing a gas of known specific gravity, e.g. air, in a ring balance 4 whose rotation alters the coupling between the grid and anode coils of an amplifier valve 8 having a meter 7 in the output circuit whose moving coil 9 oppose the rotation of the ring balance 4, is characterized in that the energization of the magnetizing coil 12 of the meter 7 is made proportional to the atmospheric pressure at the open ends of the columns 1, 3 by a barometer 10 which adjusts a potentiometer 11 in the energization circuit. The reading of a meter 13 in the amplifier output circuit is therefore indicative of the ratio of the specific gravities independently of the atmospheric pressure. The columns 1, 3 are maintained at a constant temperature.

Abstract: 1,162,577. Anaerobic polymerization and bonding. LOCTITE CORP. 18 May, 1967 [18 May, 1966], No. 23226/67. Heading C3P. A part for assembly with a co-operating part to enter into sealed engagement therewith is coated on at least part of the surface thereof with a liquid composition which can polymerize to form a tough, solid polymer upon the exclusion of oxygen, and the coating is enveloped by an oxygen-permeable material, which envelope is ruptured upon assembly of said part and said co-operating part, whereupon the coating flows between the mating surfaces and is anaerobically polymerized. The liquid coating composition suitably comprises a hydroperoxide catalyst and a polyacrylate ester of the formula where R1 is hydrogen, halogen or a C 1 -C 4  alkyl group, and X is a chain containing at least two carbon atoms and containing no polymerizable groups other than groups of the formula CH 2 =CR<SP>1</SP>-COO-. The chain X is preferably of the formula where R represents hydrogen, a C 1 -C 4  alkyl or hydroxyalkyl group, or a group of the formula -CH 2 -OOC-CR<SP>1</SP>=CH 2 , and R<SP>11</SP> is hydrogen, -OH or a group of the formula -OOC-CR<SP>1</SP> = CR where R<SP>1</SP> is as defined above; m is an integer equal to at least 1; p is 0 or 1; and n is an integer equal to at least 1. The compositions may also contain stabilizers and accelerators; suitable stabilizers include benzoquinones, naphthaquinones and sterically hindered phenols, and suitable accelerators include amines, organic phosphites, mercaptans, ascorbic acid, quaternary ammonium salts, sulphimides and formamide. Instead of the organic hydroperoxide, the catalyst may be hydrogen peroxide or a peroxide or perester which can form a hydroperoxide in situ. The envelope coating may consist of gelatin or a gelatin/algin mixture; alternatively, the envelope may be generated in situ by polymerizing the outermost region of the polymerizable composition to form a skin, e.g. by exposing the composition to an environment of SO 2 , H 2 S, HCl, SeO 2  or NO 2 ; in another embodiment, the polymerizable composition is encapsulated in a suitable envelope, and the resulting capsules are then secured to the surface of the part to be assembled. In examples, tetraethylene glycol dimethacrylate is used as the polyacrylate ester.
