Title: Improvements in or relating to the manufacture and construction of hollow bodies composed of resin bonded fibrous material
Inventor: POLLARD HAROLD JOHN
IPC: B29D22/00
Filed: 1955-12-22
Abstract: 824,930. Moulding hollow bodies. BRISTOL AIRCRAFT Ltd. Dec. 12, 1956 [Dec. 22, 1955], No. 36834/55. Class 87(2). In a method of moulding a hollow body comprising a shell of resin bonded fibrous material provided with an internal stiffening structure having faces jointed to the inner surface of the shell, the stiffening structure is arranged, with said faces in the relative positions desired in the hollow body, in assembly with a former to define an external surface complementary with the internal surface of the shell, and strip fibrous material is wound around the external surface in layers of crossing strips, the material being impregnated with resin either before or after winding, the resin allowed to set, and the former removed. In the manufacture of a drop fuel tank for aircraft comprising two original end shell portions connected by a tubular shell portion, the stiffening structure comprises metal joint rings la, lb, Fig. 1, angle section frames 2, 3 of resin-impregnated asbestos fibre, sockets 4, 5 for receiving screw-threaded plugs (not shown), diaphragms 9, 10, and 11 of re-inforced asbestos fibre and incorporating metal mounting fittings 9a, 10a, 10b, and metal sockets 12, 15 and 16. The stiffening structure is assembled with a former comprising a tube 34, having. sleeves 39, 40 for spacing the diaphragms 9, 10 and 11, and on which are mounted end fittings 18 slotted to receive the ends of metal cones 23 having cylindrical skirts 24 aligned with the edges of the diaphragms 9, 11, respectively, by Z-section metal rings 25, and around each cone 23 three or more segments 28 of wood or framed resin. Removable cast collars 32, 33 of wax or a low melting point alloy space the edges of the diaphragms 9, 10 and 11. One end fitting 18 is slotted to receive a driving shaft by which the assembly may be rotated, the other end fitting 18 (not shown), being supported for rotation. After assembly the outer surface of the structure is coated with a mould release agent, e.g. wax, and is rotated to wind a glass fibre roving thereon. The latter may be led from a single spool to a carriage reciprocating parallel to the rotating structure and carrying a tray of setting liquid resin. for coating the lower surface of the roving. The first winding a, Fig. 4, is applied when the carriage is moving in one direction, and a winding b is applied on the return movement of the carriage so that the turns cross at a substantial angle A. On the next forward movement a winding c is applied having turns disposed between those of the winding a, and further windings are applied until at least one complete layer of each pitch angle has been applied. Alternatively a complete layer of one pitch sense may be wound using a number of spools before next layer of opposite pitch sense is applied. When the resin has set the shell is cut through at the joint lines of the rings la, lb and the frames 3, and the parts of the former are removed.

Title: Improvements in and relating to separating fat from batches of free fat containing portions
Inventor: PERCIVAL ROBERT CLARK
IPC: C11B1/00
Filed: 1954-12-21
Abstract: Fat is separated from batches of free fat-containing portions obtained by the method of Specification 748,814 by conditioning the free fat-containing portions, after their release by the high frequency vibrations, to a temperature immediately below the coagulating point of the protein matter but sufficiently high to maintain the free fat in the molten state, passing the free fat-containing portions through screen to separate the major part of the solid material, and then centrifuging the remaining fat-containing portions to separate the free fat from blood, soluble albumins &c.  The free fat-containing portions are preferably conditioned by the addition of warm water thereto which is removed in the centrifuging step.  The proportion of water is preferably 50 per cent or more of the fatty portions and its temperature may be 55 to 65 DEG C., the resulting temperature being below 50 DEG C.  The liquid fat from the centrifuging may be re-refined by heating to 70-80 DEG C. to facilitate the separation of remaining water and other impurities by a final centrifugation. The conditioning step may also be effected by controlled heating.

Title: Improvements in or relating to internal combustion engines of the liquid fuel injection type
IPC: F02B19/04
Filed: 1930-12-16
Abstract: 369,229. Oil engines. RICARDO, H. R., 21, Suffolk Street, Pall Mall, London. Dec. 16, 1930, No. 37929. [Class 7 (iii).] In a liquid-fuel injection engine of the type having an offset combustion chamber E which communicates with the cylinder through a port E<1> and in which turbulence of the air in the chamber is produced to facilitate the mixing of the fuel supplied by an injector J, a portion of the air is entrapped by a projection B<1> on the piston as it enters an adjacent chamber D near the end of the compression stroke ; one or more restricted and tangential passages F<1> connect the chambers D and E, and the highly compressed air passing to the chamber D accentuates the turbulence therein. The port E<1> is of sufficient area to permit a comparatively free gas flow therethrough, and it may be so arranged as to produce a preliminary whirling of the charge in the combustion chamber either in the same direction or opposed to that effected by the passage F<1>. A valve G<1> controls an air inlet port G arranged in the top of the chamber D, which may be of other than cylindrical form and located coaxially or eccentrically in the cylinder head, the projection on the piston being correspondingly shaped and located. An exhaust valve H<1> is located in the top of the combustion chamber E. Alternative positions are provided for the fuel injector J.

Title: Improvements in or relating to valves for fluid-pressure operated devices
IPC: F16K31/363
Filed: 1957-12-09
Abstract: 828,503. Hydraulic pit props. EGGEMANN, W., and CAMPENHAUSEN, E. VON, [trading as SCHWARZ K.G., H.], Dec. 9, 1957 [Dec. 18, 1956], No. 38145/57. Class 20(2) [Also in Group XXIX] A valve suitable for controlling an hydraulic pit prop &c. comprises a closure member 28 arranged to be urged towards a seat 38 by the pressure in the pressure chamber 21 of the pit prop and having a stem 27 mounted in a bore 25 of a carrier 23 which is also subject to the pressure in the pit prop and is movable in the housing 37 by a cam 22 carried by a shaft 20 having an actuating lever 18. The arrangement is such that when the shaft 20 is turned to withdraw the cam 22 from the carrier 23 the latter is urged towards the right by fluid pressure and withdraws the valve member 28 from its seat by means of a cross piece 32 engaged in a slot 36 in the stem 27 to allow the pressure chamber of the pit prop to be exhausted through a port 39. To enable the carrier 23 to withdraw the valve member 28 from its seat the effective area of the carrier 23 is made greater than that of the valve member. When the chamber 21 of the pit prop is to be pressurized the cam 22 is turned to move the carrier 23 to the left. The valve member 28, however, has lost motion in its connection 32, 36 with the carrier 23 whereby it may remain open so long as pressure in the port 39 exceeds that in the chamber 21. When the chamber 21 is filled the pressure rises and causes the valve member 28 to close. The connection 32, 36 may be such that a small amount of lost motion is taken up as the carrier 23 moves to the right before opening the valve member 28. This causes the pressure in the chamber 21 to fall slightly to facilitate opening the valve. The valve member 28, instead of being a disc as shown, may be, e.g., a ball, taper plug or needle.
