Title: Improvements in or relating to cements, concretes and mortars
IPC: C04B28/26
Filed: 1929-08-27
Abstract: 338,242. Battersby, J. W. Aug. 27, 1929. Cements, Portland; concretes and mortars.- A waterproof cement is prepared by adding a powder of colloidal readily soluble water-containing alkali silicate (prepared, e.g. as in Specification 11959/14, [Class 1 (iii), Oxides &c., Metallic], in amounts of 2-5 per cent to Portland cement or lime concrete or mortar prior to mixing with water. The product has high strength, low porosity, and greater resistance to acids. The silicate is preferably added to the cement clinker before the latter is ground. The initial set period may be controlled by varying the amount of water in the silicate which may be from 10-30 per cent, the period being shortened with increasing amounts ot water. For some purposes, e.g. sealing porous places or "weeps" in floors, &c. a mixture of equal parts of cement powder and silicate powder may be used. The advantages of the invention are not obtained if .the silicate is added to wet cement.

Title: Omnidirectional beacon antenna
IPC: H01Q3/14
Filed: 1958-08-15
Abstract: 842,063. Directive radio systems. STANDARD TELEPHONES & CABLES Ltd. Aug. 15, 1958 [Aug. 19, 1957], No. 26295/58. Class 40(7). The invention relates to an aerial system for a "TACAN" radio beacon and provides an aerial system of smaller size that those of the prior art whilst retaining a satisfactory fieldstrength pattern. In particular the pattern in the vertical plan has a maximum just above the horizontal, as is desired and then falls away substantially evenly as the elevation angle increases up to an angle of the order of 60 degrees. The embodiments described are for the production of a rotating beacon radiation pattern with a single main lobe and nine equally spaced minor lobes superposed thereon. In a first embodiment the radiating element 1 in the centre of the system is a cylindrical cup, quarter of a wavelength high, mounted over a central stationary part 6 of a ground plane. The element 1 is fed by a transmission line 12, 13. The rotating part of the system is mounted on a rotatable extension 7 of the ground plane capable of being driven by a motor 11. A choke joint 8, 9 is arranged between the two parts of the ground plane. Nine folded unipoles 2 are provided on the plane 7 equally spaced round the element 1 and each is fed by, and matched to, a transmission line 3 leading radially inward to a vertical pick-up element 16. The upper ends of the elements 16 are connected by a ring 17 supported on a dielectric cylinder 18. The folded unipoles are thus fed indirectly from the same source as element 1. Also included in the rotating structure are the nine parasitic elements 4 for the production of the minor lobes and a single inner parasitic element 4a mounted on the cylinder 18 which produces the major lobe. An explanation of the theory of operation of the folded unipoles in conjunction with the centre element is given and refers to Figs. 5 to 9 (all not shown). Fig. 4 shows a section, similar to that of Fig. 2, through another embodiment in which the central element is a dipole 19, 20 and all the elements are spaced above rotatable ground plane 33. The ground plane carries a dielectric cylinder 31 which supports inner parasitic element 32 and also nine radially arranged and equi-angularly spaced supports 30 each bearing in printed circuit form an outer parasitic element 25 and a folded dipole 24, coupled to a balanced pickup element 27 by a transmission line 26. The outer ends of the pick-up elements are coupled by upper and lower conductive rings 28 and 29 mounted on the dielectric cylinder 31.

Title: Anti-static photographic film
Inventor: KLOCKGETHER HELFRIED
IPC: C08F8/28
Filed: 1957-08-21
Abstract: Acetals are derived from linear organic polymers containing hydroxyl groups and aromatic aldehydes containing at least one alkali metal sulphonate group.  The acetals also may contain residues of aromatic aldehydes not containing sulphonate groups. The acetals may be derived from polyvinyl alcohol which may contain some acetyl or propionyl groups, partially hydrolysed copolymers of vinyl chloride and vinyl esters, and copolymers of vinyl esters with acrylic acid, methacrylic acid, fumaric acid, maleic acid anhydride and esters of these acids, styrene, vinyl alkyl ethers, ethylene or propylene. They may be obtained by reacting polymers of vinyl esters in alcoholic solution with an aldehyde sulphonic acid whereby acetalization occurs with cleavage of the ester groups.  In an example, polyvinyl alcohol, benzaldehyde and sodium benzaldehyde-2 : 4-disulphonate are heated in methanol with sulphuric acid catalyst and the reaction mixture neutralized with caustic soda diluted with methanol and precipitated by adding acetone to yield a polymer soluble in a mixture of water or acetone and methanol.  By a similar method, a partially hydrolysed copolymer of vinyl chloride and vinyl acetate is reacted with sodium benzaldehyde-2 : 4-disulphonate. The acetal may contain dyes or be mixed with photographic gelatino-silver halide emulsions, or be used in protective layers by mixing, for example, with gelatin, saponin and 1 : 3 : 5-triacryloyl perhydrotriazine-1 : 3 : 5.

Abstract: 296,211. Murray, T. B., Albion Motor Car Co., Ltd., and Watt, J. Oct. 7, 1927. Channels and reservoirs in universal joints.- In a universal joint of the Hooke's type, oil is fed centrifugally to the trunnion bearings through ducts 12 from an annular recess 10 formed on the interior of the trunnion ring 3, - and the recess is replenished from a closed oil reservoir rotatable with the joint, the arrangement being such that oil cannot pass directly from the reservoir to the bearings during rotation. As shown in Fig. 1, the joint is enclosed by interengaging spherical covers 6, 7, of which the former is carried by the driving flange 2 while the latter is slidable under the control of a spring 8 on the driven member 4. To influence oil contained in the chamber enclosed by the members 2, 6, 7 to enter the recess 10, one or more vanes 16 is carried by the flange 2, the free end of the vane being disposed within the ring 3, whereby, when rotation is interrupted, oil will flow from the reservoir wall into the recess. In the form shown in Fig. 2, the recess is formed on a central flange 18 in the ring 3, and cover plates 23 are secured to the sides of the ring so as to form a reservoir 24 which may be charged through ducts 28, 29. Vanes 25 are fixed to the plates 23.

Tubes, approaching the mill 1 along the conveyer 2 are sensed by movable vane detectors 10 and their size determined. A placement and levelling device at a position 20A, Figs. 2, 3 (not shown), raises the tube at the position b and transfers it through the positions c, d to e by means of hydraulic rams. At the position e a plane plate proximity detector 13 senses a metal band attached to the tube whereupon the control console 7 effects the operation of the multi-position pick-up device 4 which has an arm 5 fitted with a suction head 6. The pick-up device 4 transfers the tube to the first station on the mill 1 where it is sensed by the vane detector 11 which prevents further tubes being placed in the same position. On rotation of the mill the washed tube in the final station is removed by the pick-up device 4 and passed through a similar mechanism to that described on to the output conveyer 3. The cycle is automatically repeated.
