Title: Improvements in pre-set tuning devices for radio receiving apparatus
IPC: H03J5/16
Filed: 1939-07-24
Abstract: 531,494. Push button tuning mechanism. PHILIPS LAMPS, Ltd. July 24, 1939, No. 21475. Convention date, July 25, 1938. '[Class 37] In wireless receivers provided with station selector means, e.g. a dialling disc, push buttons, key board &c. co-operating with a number of positioning discs 5-8 frictionally mounted on a shaft 4 through which a motor 28 drives the tuning condenser shaft 1, the drive is effected through two friction clutches one 33, 35, of which has a larger and the other 36, 37 a smaller friction couple than that of the couple between the positioning discs and the shaft 4. The motor drive is normally effected through gearing 44, 45, 42 and the clutch 36, 37 having the smaller torque but by pressing the knob 43 the drive is transferred through the clutch 33, 35 having the larger torque to effect the presetting of the locating discs to the correct tuning positions, the frictional contact between the disc 5 and the shaft 4 being overcome by the more powerful clutch 33 35 and the disc being held stationary by the detent 14 until the correct tuning position is located. The reduced torque of the clutch 36, 37 is obtained by making the disc 36 of smaller diameter than the discs 33, 35, 37 or by using plates made of different materials. Depression of a push button 29 permits a detent 14 on the end of a lever 15 to engage in groove 10 in the disc 5 the groove having high and low parts 11, 12 separated by a notch 15. Movement of a lever 15 starts up the motor by completion of the circuits 25, 26, 27 through the lever 15 contacting with contacts 23, 24 and the disc is rotated in either direction according to the position of the detent 14 on the higher or lower portion of the groove until the detent 14 drops into the notch 13 whereupon the lever is freed from the contacts 23, 24 and the drive is arrested at the correct tuning position. Frictional contact between the discs 33, 35, 36, 37 is maintained by an adjustable spring 39.

Title: Cation exchange membranes and their preparation
Inventor: BOURAT GUY
IPC: C08L25/18
Filed: 1969-04-29
Abstract: 1,220,776. Cation exchange membranes. RHONE - POULENC S.A. 29 April, 1969 [29 April, 1968], No. 21897/69. Heading C3P. [Also in Division B1] A cation exchange membrane made of a homogeneous mixture of (a) a poly-p-vinylphenol, which is optionally halogenated, and which is cross-linked via the oxygen atoms of its hydroxyl groups and substituted by cation exchange radicals, and (b) an inert polymer may be prepared by forming a layer of a solution in and organic solvent of the inert polymer and the poly-p-vinylphenol and then, either successively or simultaneously, evaporating the solvent, cross-linking the poly-p-vinylphenol by reaction with its hydroxyl groups and introducing the cation exchange radicals. The inert polymer is one which does not interfere with the cross-linking of the poly-p-vinylphenol or the introducton of cation-exchange radicals and in particular is inert to halogenated compounds and sultones. Suitable polymers are polyvinyl chloride and a copolymer of vinyl chloride with vinylidene chloride or vinyl acetate. Cross-linking may be effected by dehydration in an inert medium containing hexamethylphosphotriamide or dioxane or by treatment of the salt of the polymer with a compound containing at least two reactive halogen atoms e.g. o- or p-xylylene dihalide or 3,3 - bis(halogeno - methyl) - oxetane. Crosslinking and radical introduction may be effected by reaction with a polysultone e.g. spirobi-2: 2<SP>1</SP>- propanesultone. Exchange radicals may be introduced by sulphonation with e.g. sulphuric acid, oleum, chlorosulphonic acid or a monosultone e.g. propanesultone. The membrane may also contain a quaternary ammonium salt and a hexaalkyl phosphotriamide. In the examples are also used poly(4 - hydroxy - 3 - chlorostyrene), poly(4 - hydroxy - 3 - bromostyrene), methyltrilaurylammonium chloride and tributyl orthophosphate.

Abstract: 689,552. Disc brakes. KNIEPKAMP, H. E. Sept. 18, 1951 [Sept. 18, 1950; Nov. 9, 1950], No. 21923/51. Class 103 (i).  In a disc brake of the type in which two brake lining carrier members 4 and 9 are spread apart into engagement with the flat internal sides of a brake drum by the action of balls or rollers 8 between inclined surfaces 7 and 10 as a result of the circumferential movement of one of the carrier members (the member 9 as shown), the members 4 and 9 are so shaped as to form a part of a ring only instead of the usual complete ring. As shown in Fig. 2, the brake is applied by the action of a lever on the brake spindle 13 engaging an abutment 14 on the member 9. In Fig. 7, the invention is adapted for use on motor vehicles, the stationary brake member 3 being provided with T-shaped abutments 17 which engage corresponding recesses on the carriers 4 and 9 in such a way as to operate in both directions of rotation of the brake drum. When possible it is arranged that the brake self-energizing force PS, the operating force PZ and the line connecting the centre of the balls shall coincide to reduce movements on the balls. Where this is not possible forces PS and PZ may still be arranged so that their movements are practically eliminated. To allow assembly of the brake members in drums having integral side flanges, as in Figs. 12 and 13, it is necessary to use carrier members 28 and 29 having cut-away corners so that they may be inserted through the end opening of the drum and then moved radially into position. Screws 30 may be provided for holding them while the holders 33 on the stationary brake member 34 are slid into the recesses 31 and 32. Fig. 14 shows a construction of carrier member comprising two shaped steel parts 35, and 36, on which the braking forces PBR, PZ are applied, cast into a light metal body. Radial apertures 40 may be provided in the body for better heat conduction and for reducing weight.
