Title: Saddle-trees
IPC: B68C1/02
Filed: 1971-09-17
Abstract: 1384062 Saddles E GOEDICKE 18 Dec 1972 [17 Sept 1971] 43358/71 Heading AIM Saddle tree for a riding saddle is moulded of rigid expanded plastics material such as foamed polyurethane and includes a reinforcing layer 6 which may be sheet polyethylene and has holes 7 to key it to the outer moulding. This reinforcing layer is extended out of the moulded plastics to form the forward points 3 to which the front iron (not shown) is attached by rivets through the holes 8. In manufacture, the thermo-plastic reinforcing sheet is held in the mould while the polymerisation of the outer material produces sufficient heat to soften the sheet and deform it permanently to the required shape. Specification 1245445 is referred to.

Title: Improvements in the production of impact-resistant polystyrenes
IPC: C08F279/02
Filed: 1960-12-22
Abstract: Impact-resistant polystyrenes are produced by the polymerization of a styrene which contains a stabilized natural or synthetic rubber in solution or in finely divided swelled homogeneous state, and from 0,1 to 5%, based on the total weight of the mixture, of one or more esters of one or more acrylic acids, e.g. methyl, ethyl, propyl and butyl acrylates and methacrylates.  In addition to styrene itself there may be used substituted styrenes, e.g. alphamethyl styrene and vinyl toluene. As a stabilized synthetic rubber there is specified a butadiene-styrene copolymer containing 1,2% of styrenized phenol. The polymerization of the mix may be carried out in bulk, or in suspension or emulsion in water containing suspending and emulsifying agents.  Polymerization catalysts may be employed, e.g. di-tert. butyl and benzoyl peroxides, tert. butyl perbenzoate, azodiisobutyronitrile and potassium persulphate.

Title: Filtering or separating block
IPC: B01D25/26
Filed: 1961-12-15
Abstract: 926,600. Filters and separators. J. MULLER. Dec. 15, 1961 [Dec. 15, 1960], No. 45029/61. Class 46. A filter block comprises porous filtering elements 2, insert plates 5 and backing plates 6 on a perforated central tube 4, each insert plate being formed with integral ribs 10, 12 projecting from its surface, the outer edges of the ribs defining a concave surface, each backing plate being formed with correspondingly placed integral ribs 11, 13, whose outer edges define a corresponding convex surface, and resilient means, e.g. a coil spring 31, acting on the insert and backing plates, through a slidable pressure member 35, to hold the elements firmly between the plates. The ribs on the insert plates and backing plates define cavities 9 and have gaps 14, 15 respectively formed between them. If an element should disintegrate, the particles which become detached therefrom immediately obstruct the gaps 14, 15 and prevent the further passage of non-purified liquid from that particular part of the filter block, so that untreated liquid is not allowed to pass through to the outlet. Each insert plate and backing plate is respectively provided with an outer frame 21 lipped at 19 and having outlet passages 30, and an inner ring 27 having inlet grooves 28, 29, the plates being formed with serrations 20, 21, 25, 26 and 23, 24 respectively to grip the element. The filter block is supported axially by an end fitting 37 bearing against an abutment member attached to an inlet pipe 38 through which liquid is supplied under pressure and is inserted in a casing 34, perforated at 39, which has a perforated washer 32 and a condenserdeflector 33 attached to the other end. When the filter block is used to separate immiscible liquids, the heavier liquid falls through the perforations in the casing and the lighter liquid passes through small horizontal passages extending through the condenser-deflector, which condense any froth that may form.

Title: A method for the purification of palm oil

Abstract: 1,272,170. Purifying palm oil. ALFA-LAVAL A.B. 22 Sept., 1970, No. 45062/70. Heading B1D. [Also in Divisions C4 and C5] Crude palm oil is purified in a vibrating screen apparatus 2, a settling tank 6 and centrifuges 10, 19 in at least some of which a steam atmosphere is maintained to prevent the oil from oxidising. In Fig. 1 the crude oil is fed to screen 2 whichremoves coarse solids, and the oil-water mixture is pumped to tank 6 (Fig. 2) from which sludge is withdrawn at 40 past valve 43 and returned to the screen, oil is withdrawn at 9 and water at 18. The water outlet 37 is vertically adjustable. A float in vessel 4 controls a valve downstream of pump 5 to maintain level 8. The oil and water pass from tank 6 to respective centrifuges 10, 19. Centrifuge 10 removes residual water and passes the oil to vacuum drier 13 and cooler 16. Centrifuge 19 extracts residual oil and returns it to vessel 4. Steam is delivered by lines 24, 25 to vessel 4 and tank 6, from which it passes through lines 9, 18 to the centrifuges. Alternatively the crude oil is fed directly to tank 6, and screen 2 receives only the sludge through line 40. In this case there is no steam supply to the vessel 4, as oxidation of the small amount of oil passing through the screen is tolerable.

In a continuous combined drawing and bulking (or irregular crimping) process, an undrawn synthetic polymer e.g. nylon, multifilament, twisted or twistless yarn (or a plurality thereof) is drawn (with a stretch ratio of at least 2:1) by pairs of rollers in one or two stages in at least the second of which the stretch in the yarn is concentrated at a non-rotatable, optionally heated, snubbing pin. The drawn yarn is immediately and directly forwarded, with a mechanical overfeed not exceeding 20% and heating (as by heated draw rolls) to ensure or assist in the yarn contraction or relaxation, to a stuffer-box crimping apparatus, and set or allowed to set by additional and/or residual heat. An air jet may act on low tension span(s) of yarn between supply package and feed rolls of a drawing mechanism and between the (final) draw rollers and the stuffer-box to intermingle the filaments and/or to cool them before wind-up. In the stuffer-box crimper shown, a conglomerated, columnar mass of filaments passes into a weight-loaded setting chamber 39 limited vertical movements of which, on its flexible, spring, supporting cantilevers 43, 45, in response to variation in the level of yarn therein, operates a microswitch 57 to select a voltage which is rectified and applied to a magnetic particle brake 61 to adjust correctively the tension in yarn withdrawn from the chamber against the resistance of an adjustable flap 53, so that the yarn level in the chamber is maintained constant.
