Title: Means for bonding fibrous materials
Inventor: RAWSON HECTOR ELSWORTH
IPC: D04H1/00
Filed: 1964-03-03
Abstract: A method of forming fibrous webs to produce batting, padding or stuffing material consists in feeding and laminating upon a continuously moving conveyer, which runs at right angles to a camel-back or like feed mechanism, a web from a carding machine, and spraying each lamination with a suitable liquid bonding agent.  In the arrangement of Fig. 1 (not shown), the spray nozzles 6, 7 are mounted on a frame 5 which moves with the feed mechanism, the angular disposition of the nozzles being variable. The spray nozzles may be attached to a carriage 10, Fig. 2 (not shown), capable of independent motion, relative to the feed mechanism, along a rail 11, the spray nozzles in this case may be fixed, Fig. 2 (not shown) or the angular disposition of each nozzle may be variable, Fig. 3 (not shown).
Patent GB-1547808-A (GB)
Title: Continuous stationery addemblies
IPC: B41L1/26
Filed: 1976-03-05
Abstract: The continuous paper arrangement has a plurality of recording layers (1, 2, 6), the outer layers (1, 2), which are connected to each other along their length by fixing lines (4), having tractor perforations (3) at the longitudinal edges for the tractor feeding of the arrangement by the printing unit of an office machine. In order that the leading length of stationery which, with each engagement of the tractor feed device, has already passed through the printing device should not be wasted each time the arrangement is used, the arrangement is so designed that, when the last length of stationery printed in each case is removed, at least the longitudinal edges with the tractor perforations remain on the arrangement so that, when the arrangement is used again, these can serve as a drive web for the tractor feed. To this end, in addition to transverse lines of weakening (15), two longitudinal lines of weakening (5, 5a) are provided within the fixing lines (4) on an outer layer (2) and make it possible to separate this layer, and intermediate layers (6) adhering thereto, of a length of stationery from the other external layer (1) remaining on the arrangement. <IMAGE>

Title: Improvements in or relating to fluid pressure devices
IPC: F01C21/08
Filed: 1944-05-12
Abstract: 598,766. Rotary pumps and motors. STEVENS, A. H. (Manly Corporation). May 12, 1944, No. 9127. [Class 110 (ii)] In a rotary motor or pump of the outwardly-sliding vane type, the radially - acting hydraulic forces on each vane are balanced during its passage through the high-pressure inlet area, and each vane is acted on by a spring, having two or more arms with one arm engaging the vane and another arm engaging the bottom of the vane slot. The rotor 15, Figs. 1 and 2, is disposed between stationary cheek plates 34, 35, and is mounted loosely on a splined shaft 20 so that it can move axially or rock slightly to take up a position determined by the cheekplates. The latter have ports 38, 39, Fig. 4, which communicate by means of radial grooves with inlet ports 36 and outlet ports 37 respectively to apply fluid pressure to the inner ends of the vanes 17-to balance the pressure on their outer ends. Inlet and outlet passages formed in the body 10 communicate with the corresponding ports 36, 37 in plate 34 only ; plate 35 functions only to provide hydraulic balance of the rotor and vanes in an axial direction. A cheek-plate for a reversible motor has supplementary balance ports 132, 133, Fig. 5, which are supplied with high-pressure fluid irrespective of the direction of rotation through either one of two non-return valves 142, 143. The vanes are pressed outwards by wire springs 50 comprising straight or curved arms joined by coiled portions ; several modified forms are described. As an alternative, a flat leaf type of spring, Fig. 14, may be used. The vane 17 may be relieved at the inner end as at 220 and 221, Fig. 15, to avoid bearing on a sharp tip when tilted in its slot by inequality of fluid pressure on the opposite faces of its outer ends. The invention may be applied to variable capacity motors or pumps of the type described in Specification 564,769.

Title: Improvements in and relating to the manufacture of titanium dioxide
Inventor: WIGGINTON RAYMOND JAMES
IPC: C01G23/053
Filed: 1960-03-17
Abstract: Titanium dioxide suitable for incorporation in vitreous enamels and glazes is prepared by a process wherein an aqueous solution at 40 DEG to 70 DEG  C. of titanium sulphate having a concentration of titanium from 120 DEG  to 180 gms./litre calculated as TiO2 is added to a proportion of hot water such that after complete mixing the concentration of dissolved and undissolved titanium is from 75 to 95 gms./litre calculated as TiO2, the temperature being maintained above 70 DEG  C. until after completion of hydrolysis, a minor proportion (e.g. 5 to 40%) of the precipitate so formed is separated and, while substantially free of sulphate-ion, is peptized by treatment with hydrochloric acid to form a suspension having an acidity of about 2, the peptized hydrous titanium dioxide is mixed with the remainder of the hydrous titanium dioxide precipitate and the mixture, while free from loosely bound sulphuric acid, is subjected to calcination, e.g. at 700 DEG  to 1150 DEG  C., if desired, with the addition of oxides of, for example, tungsten, tantalum, molybdenum or antimony.  The minor proportion may be rendered free of sulphate-ion by washing with water to remove loosely bound sulphuric acid, treating with alkali, e.g. ammonia or sodium carbonate, to neutralize the residual acid, and washing to remove the salt thus formed.  The remainder of the titanium dioxide precipitate is rendered free of loosely bound sulphuric acid by washing before or after the separation of the minor proportion and, if desired, free of sulphate ion by the above process.  Before peptizing, the minor proportion if inconveniently thick may be slurried with water to a concentration of 200 to 700 gms. of titanium dioxide per litre. The addition of the titanium sulphate solution is advantageously completed within 5 to 40 minutes, and the temperature of mixing is preferably from 90 DEG  C. up to the boiling-point of the mixture. The titanium sulphate solution is advantageously one obtained by the sulphation of ilmenite or a mixture of ilmenites and/or a titanium enriched material prepared from ilmenite or a mixture of such materials.  The sulphation liquor preferably has a factor of acidity of 60 to 70% and a TiO2 to iron ratio of 1.2 : 1 to 3 : 1.
