Title: Ground surface for athletic tracks and other uses
IPC: E01C13/06
Filed: 1952-10-24
Abstract: 757,385. Ground surfaces; wood block flooring, &c. GARTI, M. Oct. 24, 1952 [Oct. 25, 1951], No. 26772/52. Classes 20(4) and 107. [Also in Group XV] A ground surface for athletic tracks and other purposes comprises a resilient layer made up from a finely divided material, covered with a plurality of tiles interconnected by means allowing the tiles a limited relative displacement including a vertical movement and having a covering surface layer above said tiling arrangement. The tiles may be of e.g. wood, metal or cement. If desired the tiling may be covered by rubber or other resilient material, or the tiling may be perforated to allow for the growth of grass. The resilient layer may be composed of several sawdust-and-tar layers and may be laid on an impermeable layer. A continuous concrete layer prepared in known manner with planes of weakness, may be utilised to form the tiling layer, the division into interconnected tiles taking place by loading. In the Figure, tiles 50 are connected with cramps 54 through holes 52, 53 to give the necessary limited vertical displacement. Several other specific embodiments are described and illustrated in the Specification.

Title: Improvements in or relating to a method of and mechanism for automatically feeding individual signatures into a signature handling machine
IPC: B42B2/00
Filed: 1930-09-08
Abstract: 353,308. Pasting signatures. POLLAK, J. E., 20, Holborn, London.- (Brehmer, Geb. ; Plagwitz, Leipsic, Germany.) Sept. 8, 1930, No. 26795. [Class 16.] A signature stitching machine comprises means for uniting by paste the first and last pairs of signatures of a book. A paster bar 100 is arranged to take paste from a roller 99 and apply it to the fold of the second and last signatures. The roller is rotated intermittently by a ratchet-and-pawl, and is oscillated about a pivot 102, to apply paste to the bar 100 at the appropriate times, by a cam on the shaft 11, lever 107, and links 108, 109. The bar 100 is oscillated from inoperative position to that shown by a cam on the shaft 11 acting through a lever 110 and links 112, 113, 115. Operation of the paster bar only at the appropriate times is ensured by the provision of a counting mechanism comprising a notched disc 88a and a locking lever 89a. The latter locks the lever 110 against operation except when a lug 90a on the lever 89a enters a notch in the disc, which is intermittently rotated.

Title: Process for the manufacture of water-insoluble nitrogenous polymerisation products
IPC: C08F20/56
Filed: 1955-09-20
Abstract: Water-insoluble nitrogeneous polymerization products are made by polymerizing acrylamide alone or in admixture with other ethylenicallyunsaturated compounds, e.g. acrylonitrile, in a strongly acid aqueous solution of an inorganic acid in the presence of a polymerization promoter, e.g. ammonium persulphate, the limits of concentration of acid and the temperature being maintained such that no substantial amount of water-soluble products is formed and/or the water-absorbing power of the products are reduced in comparison with the products formed when the polymerization is carried out at a pH value not far removed from neutrality.  Acids specified are sulphuric, phosphoric, hydrochloric, perchloric, nitric and toluene sulphonic acids and a hydrochloric acid-zinc chloride mixture.  The concentration of acid employed is dependent on the acid used and is usually in excess of 2 per cent, and the polymerization temperature may be up to 120 DEG  C. and is usually within the range of 60-100 DEG  C.  The polymerization medium may also contain ions of a metal of the third to eighth group of the Periodic System, e.g. iron, and a wetting or emulsifying agent.  The polymeric products have a nitrogen content which is lower than that of the monomeric starting materials.

IPC: B21K1/04
Filed: 1919-11-04
Abstract: 144,184. Timken, H. H. Nov. 4, 1919. Bearings; hoops and rings.-Conical cups A<2> for roller or like bearings are made from rings A<1> cut from a tube A and preferably reamered out exactly to size or from a straight or arcuate strip F of material bent into a ring F<1>, and in either case the ring is squeezed into shape in dies C, D having a stripper E.

A stopper for permitting the introduction of gas under pressure into a container comprises (Fig. 1) a "crown-cork" " capsule 2 and a resilient packing disc 3 having apertures 4, 5 respectively which are not in alignment. On the application of external pressure, the packing is forced from the capsule to allow ingress of gas. A stopper for permitting the creation of a partial vacuum within a container comprises (Fig. 5) a flat rigid supporting disc 12 having an aperture 14, a resilient packing 3 having an aperture 5 and a " crown-cork " capsule 2 having an aperture 4 and a domed central part 11. On the reduction of external pressure, the packing is withdrawn from its supporting disc 12 and gas flows from the container through aperture 14 and aligned apertures 4, 5. Specification 500,954 and U.S.A. Specification 1,940,721 are referred to. Capsuling. For applying the above stoppers and simultaneously or subsequently creating the partial vacuum or excess pressure, the capsuling head 8 (Fig. 4) may be provided with a gas supply or withdrawal duct 9 terminating in a space 10 to allow passage of gas through aperture 4. For simultaneously effecting the capsuling and supply of gas or creation of vacuum, a container entering the capsuling head shown in Fig. 7 contacts and raises a central plunger 29 and so lifts a valve 41 off its seat to allow communication between the capsule of the container and a gas supply or withdrawal conduit 38. The valve 41 is returned by a spring 42 on removal of the container.

Abstract: 662,618. Making scissors, shears, and razors. ERN, C. F. Oct. 24, 1949, No. 27208/49. Class 83 (ii). In a method of manufacturing scissors, shears, or razors, a blank having the contour of one or more pairs of adjoining blades cohering along their cutting edges, is ground to produce concave profiles on both of its faces, whereupon the blank is subdivided to separate the blades from one another. When making scissors and knives, the blank is hardened before subdivision, but in the case of the thinning shears, Fig. 6, the blank is cut apart, after the grinding operation, by a punching tool to produce the toothed cutting edges, the teeth being then milled, hardened and ground. Fins y, z, Fig. 11, are left in position on the blank containing razor knives to prevent premature fracture during the face grinding operation, being finally removed by grinding. Specification 662,619 is referred to.
