Patent GB-742348-A (GB)
Title: Process for the production of alkaline earth or earth metal silicates for use as fillers, for synthetic or natural rubber and other elastomers
IPC: C08K3/34
Filed: 1953-12-08
Abstract: Alkaline earth or earth metal silicates are produced by mixing dilute alkali metal silicate and alkaline earth or earth metal salt solutions, characterized in that they are mixed rapidly and homogeneously, that the desired interaction is complete within one second and that the reaction product is removed rapidly from the reaction zone before particle growth of healing of the lattice structure is initiated.  Concentrations of solutions are selected such that the reaction mixture leaving the reaction zone contains 30-70 grms./litre of desired silicate and reaction is conducted at temperatures above 50 DEG C.  They are used as fillers for rubber, &c. Example 2, use of silicates containing silicic acid is given by way of comparison.ALSO:An alkaline earth or earth metal silicate, produced by precipitation from a dilute alkali metal silicate and alkaline earth or earth metal salt solutions mixed under such conditions that precipitation is completed within one second, is used as a filler for natural rubbers and other elastomers.  Vulcanizates filled with 40 parts by weight of silicate to 100 parts by weight of rubber have tensile strengths of at least 240 mgs/cm2.

Filed: 1921-12-20
Abstract: 186,886. Hansen, K. Oct. 4, 1921, [Convention date]. Electrodes; absorbents.-The electrodes of an accumulator before formation consist of a granulated mass of lead contained in a linen covering and are supported by a grid of lead or of a lead alloy which acts as a terminal. Mechanical pressure is applied to the contents of the accumulator by packing the spaces between the electrodes with glass-wood or similar material. Preferably the accumulator contains one more positive electrode than the number of negatives. The Specification as open to inspection under Sect. 91 (3) (a) states that the electrodes may be made from oxide of lead and in place of linen other porous material such as asbestos may be employed. This subject-matter does not appear in the Specification as accepted.

Filed: 1976-08-17
Abstract: 1506318 Differential gears A J HAYWARD 17 Aug 1976 [19 Aug 1975] 34345/75 Heading F2D [Also in Division B4] A method of removing a broken half shaft from a vehicle differential comprises removing the accessible broken part and the good half shaft, inserting a recovery device with a tubular forward end 8 so that it is coaxially aligned with the portion 6 of the broken half shaft 6 projecting from the differential, inserting a pusher device 9 through the differential from the side from which the good half shaft was withdrawn, to engage the broken half shaft portion 6 and press it out of engagement with the differential into tubular forward end 8 of the recovery device and withdrawing the recovery device and the broken half shaft. Dismantling the propeller shaft and differential is thereby avoided. Preferably the forward end of the pusher fits into the tubular forward end 8 of the pusher and is bifurcated so as to pass around the pinion shaft 5 found in most differentials. Tubular end 8 is split to give some tolerance to the diameter of half shaft it can receive. Normally end 8 is sleeved over the broken half shaft but where planet gears 4<SP>1</SP>, 4<SP>11</SP> have short projecting tubes closely enclosing the half shafts the end 8 abuts the end of the tube and may be outwardly bevelled to facilitate centring on the tube. Tool 10 facilitates one man operation. Collar 15 has annular holes to allow it to be secured to the wheel hub. Rod or tube 12 is slid through collar 15 until tubular head 13 is in position and then secured by screw 16.

Abstract: 343,132. Optical sound-reproducing apparatus. OWENS, F. H., 2647, Broadway, New York, U.S.A. Nov. 11, 1929, No. 34371. [Class 40 (ii).] Relates to devices for selectively reproducing sound from a series of photographic records arranged side by side along the length of a film, and consists in providing an apertured mask slidable across the film, to allow light passing through a transverse slit to be transmitted through any one of the records to a lightsensitive cell. The sound-record film 4 is fed past a light slit 17 by means of sprocket wheels 1, 2 which are connected by a transparent roller 3, the film being pressed against the roller by means of fingers 14, 15 connected with the slit holder 16. The slit itself consists of a tapered glass member 17 mounted within the holder 16, which is long and narrow, extending across the whole width of the film. Passing through the holder is a slidable member 19 having a single aperture 20 therein. The member 19 can be adjusted transversely in the slit holder, in order that light from a lamp 23 focused on the slit 17 may pass through the aperture 20 on to any one of a number of independent parallel soundtraces 7 .. 13 recorded along the length of the film. A light-sensitive cell 26, connected in a sound-reproducing circuit, is mounted in a casing 25 on that side of the roller 3 opposite to the slit 17, so that light falls on the cell after passing through the film and through the transparent roller.
