Title: Fibrillated Backing Fabric
Inventor: JEFFREY GEORGE MALCOLM
IPC: D05C17/02
Filed: 1966-02-03
Abstract: 1,164,823. Non-woven fabrics. COURTAULDS Ltd. 2 Feb., 1967 [3 Feb., 1966], No. 4742/66. Heading D1R. A non-woven fabric suitable for use as a backing fabric in the manufacture of carpets is composed of fibres or filaments produced by fibrillation of an orientated film of at least one crystalline polymer. The crystalline polymer is preferably a linear polyethylene or polypropy- 1ene, or a crystalline polyester. The film may be produced from a mixture of two or more normally incompatible polymers, e.g. the addition of polyamides or cellulose acetate. A process for producing the fabric comprises stretching the orientated film, cutting it transversely, separating it into staple fibres which are formed into a web which is then compacted. The strips of stretched film may be passed through a card and the resultant web cross-lapped and needled. A reinforcing scrim may be incorporated and the surface of the fabric may be heated to bond the surface fibres. The stretched film may be fibrillated in a spreading apparatus having beating rollers and air jets. The film may be crimped in a stuffer box prior to cutting.

Title: Hydraulic pump or motor
IPC: F04C2/10
Filed: 1961-02-08
Abstract: 980,918. Rotary pumps and motors. R. W. BRUNDAGE. Feb. 8, 1961 [March 22, 1960], No. 4764/61. Heading F1F. An internally-meshing gear wheel pump (or motor) of the n and n + 1 lobe type comprises a shaft 16, Fig. 1, supported on spaced-apart bearings, a sealing member 13 forming an integral part of the shaft and having a sealing surface 57 adjacent end faces of an externallytoothed gear 11 keyed to the shaft and an internally-toothed gear 12 rotatable in an eccentric ring 17 which also abuts the sealing member and a manifold member 14 fixedly mounted in the housing H. The manifold member includes an arcuate inlet port 43, Fig. 2, connected to a low pressure inlet 36 and an outlet port 44 connected by a passage 46 with a pump discharge port 37 and provides bearing support for the shaft 16. In operation, pump discharge pressure is communicated to a space 41 in the housing and exerts pressure on annular faces 84, 86 of the sealing member indicated by the vector L in opposition to a force R resulting from a summation of the pressures in the variable volume pumping chambers which force is radially offset by a distance r from the shaft axis. Radial fluid pressure forces within the pumping chambers are represented by a single force U acting normal to the shaft 16 on the centre line of the chambers. The force R applies equal and opposite radial reaction forces to the manifold member 14 and a roller bearing 54 relieving and adding respectively to the reaction forces on these members from the force U. The distances a and b of the bearings from the centre line of the chambers are chosen so that the roller bearing 54 takes approximately 80% of the load which permits the bearing between the manifold member and the shaft to be a low cost sleeve bearing. A sealing ring 75 acted upon by a spring 81 encloses a shaft seal 95. The spring 81 together with fluid pressure acting on an annular surface of the ring 75 externally of an 0 ring 76 urges the sealing ring 75 into sealing engagement with the sealing member 13 and augments the force L to further assist the sealing of the pumping chambers. The areas of the faces 84, 86 is such that the force L is slightly larger than the force R. It is stated that the invention may be applied to a rotary vane type of hydraulic pump (or motor). Specification 958,779 is referred to.
