Title: Improvements in and relating to apparatus for television and like purposes
IPC: H04N3/04
Filed: 1928-08-02
Abstract: 319,454. Wet, P. J. de. Aug. 2, 1928. Television.-In a method of scanning for television an image of the object is caused to rotate, an elementary strip of the image is picked out by a fixed radial slot in a diaphragm, and the scanning is completed by the movement of further slots intersecting the former at right angles. Light from an object to the left of the apparatus, as shown in Fig. 1, passes through optical and scanning systems x<1>, b, a, c, e, t<1> to a lightsensitive cell s', the position of which can be adjusted by means of the rack and pinion u<1>, v<1>. A set of lenses x<1> appropriate to objects at different distances may be mounted in a turret. An image of the object is formed in the plane oi a fixed diaphragm D which masks off all except a radial strip of the image admitted by a slot c, tapered or not. The rays forming the image pass through a reflecting prism b which rotates so that successive radial strips of the image are selected by the slot c. This slot is intersected by further slots e<1> in a disc e rotating at high speed, so that the image is scanned by the aperture formed by the intersection of the slots s, e'. The slots e<1> may be variously shaped Figs. 7, 8, not shown) and their width may be made adjustable by the use of two discs capable of relative angular displacement. A gauze disc may be interposed; it is stated that this has the effect of making the picture current pulsate. Alternatively the light may be periodically interrupted before falling on the cell. A square aperture in a plate o, which is geared to rotate at the same speed as the image, serves to frame the picture, and carries a mark q, Fig. 2, for use in synchronizing. The above rotating parts are driven through gearing from a motor q<1> with a governor x. For colour effects a screen s, Fig. 13, of two different filter plates s<1>, s<2> is reciprocated vertically by a connecting-rod in the form of a frame r, so that the plates s<1>, s<2> are in position for alternate scansions of the picture. The diaphragm D formed with horizontal scanning slot c co-operates with a shutter d having a slot, tapered or not, and adapted to ensure that the picture be scanned along a radius and not along the whole diameter; for this purpose it abuts on an adjustable stop p<1>. While the apparatus is running the shutter d is kept in its leftward position by linkwork controlled by the friction device g<1>, h', but when the mechanism stops the shutter d moves to the right and closes the slot s so that the light no longer reaches the cell s<1>. At the receiving station the signals may be recorded on a wax disc or by optical means. The receiver for reconstituting the picture is generally similar to the transmitter, a signal-controlled lamp being substituted for the light-sensitive cell.

Title: Improvements in the manufacture of white lead
IPC: C09C1/16
Filed: 1937-08-17
Abstract: 500,961. White lead. ROBINSON BROS., Ltd., PARKES, D. W., and EVANS, R. B. Aug. 17, 1937, No. 22602. Drawings to Specification. [Class 1 (iii)] White lead is produced by passing carbon dioxide into basic lead acetate solution under such conditions that as the reaction proceeds, the lead carbonate content of the precipitate falls to a recognizable minimum and then increases, the introduction of carbon dioxide being terminated at a point past this minimum, but before the lead carbonate content exceeds 80 per cent. The precipitate is maintained in suspension throughout the reaction by mechanical stirrers or merely by the agitation caused by the introduction of gas containing a relatively low proportion of carbon dioxide. Elevated temperatures between 18 and 60‹ C., and increased pressures, e.g. 5 to 30 lb. sq. in. using pure carbon dioxide, facilitate the production of an easily recognizable point of minimum carbonate content, a temperature of 20-26‹ C. and pressure of 10-11 lb. sq. in. being especially suitable. Employing a gas containing 13-18 per cent carbon dioxide, e.g. a gas obtained by burning coke (15-17 per cent carbon dioxide), a pressure of 80 lb. sq. in. may be used. The course of the reaction may be followed by determination of the sp. gr. of the mother liquor, which, when the precipitate is maintained in suspension, falls continuously to a point corresponding to the minimum carbonate content, and thereafter remains constant. The carbon dioxide may be introduced through perforated lead coils, and the carbonator may be water jacketed. The precipitate, which should be removed from the liquor as soon as carbonation stops, is washed and dried, preferably at 50-70‹ C. Several examples are given, the basic lead acetate solution being obtained by treating oxidized lead with acetic acid, or with the mother liquor of a previous operation.

Abstract: 303,400. Cresson, L. P. F. F. Sept. 2, 1927. Compound or composite bricks, blocks, slabs, and tiles. - Relates to rubber-faced surfacing blocks &c. for floors, walls, table tops, &c. of the kind comprising a base of cement or concrete and a facing of rubber which has been vulcanized in situ. According to the invention, an excess of sulphur above that required to form hard rubber at the interface is provided either in the base or in the rubber, so that a polysulphide is formed which permeates the inter-facial surfaces and firmly unites the rubber to the cement. The cement base may contain filler such as mineralized fibre, cocoanut fibre, sisal, jute fibre, cotton fluff, wood four, and asbestos, or may be formed of successive layers of felt or woven fabric impregnated with cement. The rubber face may be hard rubber throughout or may be in layers of hard rubber at the interface and soft rubber on the exterior. In an example, a cement base, #ths of an inch thick, composed of equal weights of cement and cocoanut fibre, has applied to it a film of rubber solution, a thin sheet, 1/50th of an inch thick, of hard rubber and a sheet #th of an inch thick of soft rubber. The whole is then vulcanized by heat and pressure. Instead of a thin sheet of hard rubber, a layer of high-sulphur rubber solution or a layer of latex composition of the required thickness may be applied.
