Title: Improvements in or relating to the production of compound bearings having a synthetic resin layer
IPC: B29B13/00
Filed: 1957-06-13
Abstract: Compound bearings are produced by applying to a preheated surface a powdered composition comprising a hardenable synthetic resin or a hardenable composition comprising a synthetic resin and a cross-linking agent therefor, in admixture with from 5 to 90 per cent by weight thereof of a particulate filler whose melting-point is substantially in excess of the temperature at which the process is conducted, which has good heat conductivity compared with the synthetic resin and which remains chemically unchanged during the process, securing the composition to the surface by sintering resulting from the pre-heating, and then hardening.  The coating may be applied by a dipping, shaking, rolling or whirling process. Suitable resins are phenol-aldehyde resins, methylol compounds of urea and of triazines, and epoxy resins containing cross-linking agents such as phenol-aldehyde resins, polyamines, amino-formaldehyde resins or polycarboxylic acids or their anhydrides.  Suitable fillers include titanium dioxide, barium sulphate, red iron oxide, green chromium oxide and solid lubricants such as graphite, molybdenum disulphide, mica or metal powder.ALSO:Compound bearings are produced by applying to a preheated surface a powdered composition comprising a hardenable synthetic resin or a hardenable composition comprising a synthetic resin and a cross-linking agent therefor, in admixture with from 5 to 90 per cent by weight thereof of a particulate filler whose melting-point is substantially in excess of the temperature at which the process is conducted, which has good heat conductivity compared with the synthetic resin and which remains chemically unchanged during the process, securing the composition to the surface by sintering resulting from the pre-heating, and then hardening.

Patent GB-890639-A (GB)
Title: Improvements relating to moulding
IPC: B29C45/56
Filed: 1958-06-13
Abstract: 890,639. Injection and compression moulding. HOOVER Ltd. June 13, 1958 [June 21, 1957], No. 19041/58. Class 87(2). In a combined injection and compression moulding machine material is injected into a substantially closed mould 15, 17, Fig. 2, and movement of the die 17 to fully closed position causes a boss 58 thereon to enter and close the injection opening 27 thereby compressing the material in the mould. The injection mechanism 11 and mould closing mechanism 12 are operated by a hydraulic system 23. In operation, a valve 65 is manually or automatically operated to supply fluid from a storage tank 63 and motor pump unit 64 to a cylinder 19 and piston 18 to close the die 17. When a platen 16 carrying the die 17 contacts hydraulic stops 34 mounted on a fixed platen, the die 17 is temporarily arrested. A valve 66 is then operated manually or automatically to supply fluid under pressure to a cylinder 30 and piston 29 to advance the injection ram 28 to force a change of material into the partly closed mould. The pressure behind the piston 18 builds up until it is sufficient to overcome the hydraulic stops. As the die 17 closes, the boss 58 enters the opening 27 and thereby produces an opening in the finished moulding. The valve 66 is then operated to withdraw the ram 28. Any excess material in the mould is forced out through a cut-out 54. Excess material in the opening 27 is retained by a dovetail groove 59 in the boss 58 and can be readily removed when the mould is reopened. Material is supplied to the injection cylinder 25 from a hopper 48 by a screw 46, Fig. 4, a heating medium being circulated through passages 40, 43, Fig. 4, and 44, Fig. 1. Modification. In Fig. 5 two or more mouldings are formed simultaneously in a mould comprising a fixed platen 90, a central die 91 and an outer die 92. The die 91 has a lost motion connection with the platen 16 comprising rods 94 and springs 95. Projections 97 on the die 92 are adapted to enter and close charging openings 100 which are connected to the injection opening 93 by mating grooves 101, 102 in the platen 90 and die 91 respectively.

IPC: B65H29/24
Filed: 1967-04-26
Abstract: 1,186,895 Delivering sheets. P LIPPKE 26 April, 1967. [22 July, 1966], No. 19121/67. Heading B8R. Sheets are conveyed to a required stacking position on an air permeable endless conveyer belt 65, Fig. 6, the sheets being held on the lower run of the belt by the connection of a selectable number of boxes 68 to a source of air at reduced pressure. The boxes are arranged in an unbroken line and define a plurality of contiguous zones, to which suction may be applied adjacent the belt. To deposit the sheets at a required position at least one of the zones adjacent the suction path may be provided with a source of sufficiently great air pressure to force the sheets off the conveyer. In the embodiment of Fig. 6 web 100 is cut into sheets by cross-cutters 3 after being inspected for faults at station 61. Good sheets are deposited at77whilstfaultysheetsare depositedat78by changing the distribution of suction and pressure air. In the embodiment of Fig. 4, sheets fed to conveyer 31 by separators 27 are deposited on either table 40 or 41 by arranging flap valves 33 (connecting adjacent boxes) so that suction is applied up to the required stack and pressure air thereafter. Vacuum roller 29 and blower 39 assist transport. In the embodiment of Fig. 9, sheets 23 are held on the upper run of conveyer 88 by suction box 91, inspected at 110 and delivered either to stack 99 by passage over segment 95 of suction roller 90 where there is no suction, or stack 98 by deflection by blower 103 on to the lower run of the conveyer associated with suction box 92. This box carries valve 112 which may be opened to advance the position at which the sheet is deposited. In the embodiment of Fig. 10, sheets are either gripped by the conveyer 114 (with associated suction box 120) and delivered to stock 126 or they are transferred to a second conveyer and deposited from there on to a selected stock by control of suction air within boxes 121. In the embodiment of Fig. 11, the suction boxes are formed from a box 146 dividable by flaps 147 and a compressed air box 152 is provided which is connectable along any required length to box 146 by flaps 153. Sheets are held up by suction from box 146 and compressed air flowing from box 152 to that part of box 146 below the open flaps propagates a surge of pressure along box 146 which forces the sheet, trailing end first on to stock 151. Slower moving conveyer 155 assists stacking.

Abstract: 1,270,216. Non-woven fabrics; yarns; woven fabrics. J. P. STEVENS & CO. Inc. 22 April, 1970 [22 April, 1969], No. 19262/70. Headings D1K, D1R and D1W. [Also in Division F2] In a fabric for providing thermal insulation, hollow filaments contain a liquid solvent in which a gas is dissolved. A fall in ambient temperature causes freezing of the liquid with a reduction in the amount of gas dissolved therein. The expelled gas inflates the hollow filaments to increase the thermal insulation properties of the fabric by reducing the transmission of air or moisture through the fabric. In a further embodiment, a composite material is formed of the inflatable filaments embedded in a layer of fibres which increases in thickness with a reduction of temperature. The filaments may be arranged in groups, each of which contains a different solvent, which freeze at different temperatures, thus providing a progressive increase of thermal insulation as the temperature falls. Examples of the gases and the solvents are, respectively, ammonia, carbon dioxide, dimethyl ether and acetophone, water, polyethylene glycol.

In a gas plug-socket a tubular member 8 which is rotatable but axially non-displaceable is sealed against the socket 1 by a sealing ring 7, and a plug 25 is non-rotatably coupled to the member 8 by balls 17 in the member and which are pushed radially inwards to engage in lateral recesses of the plug when the latter rotates the member. The member 8 is formed with a valve seat 10 and is provided with cam surfaces 13 which operate on a pin 11 carried by an axially-displaceable, spring-loaded valve 12 and to open the valve when the member 8 is rotated. There is a fixed stop pin in the member 8 which engages in a segmental recess of the cap 3 to limit rotation of the member between the open and closed positions of the valve, and a spring-operated pin 21 which normally locks the member 8 against rotation but which, by insertion of the plug 25, is lifted and caused to drop into one or other of two bores in the end 19 to produce an audible locking sound indicating the beginning of opening and open positions of the valve. A screen 16 prevents unauthorised actuation of the valve.

Title: Manufacture of Artificial Milk.
Inventor: ERSLEV KNUD
IPC: A23C11/10
Filed: 1918-11-28
Abstract: 121,133. Erslev, K. Nov. 28, 1918. Butter substitutes.-In making margarine or artificial milk from vegetable substances such as soya beans, earth nuts, pine kernels, sesame seeds, leguminosae in general, coco-nuts, palm kernels, or almonds, especially such as contain sugar and lecithin, the material is treated with a solvent to extract fat and then extracted with alcohol. Before the fat is extracted the material may be dried at a temperature high enough to render the enzymes inactive. The lecithin is removed from the alcoholic extract either by partial evaporation or by precipitation with a solution of sodium chloride, and the remaining alcoholic extract is evaporated to dryness. The bitter substances are removed by treatment with strong alcohol or acetone. The residue from the alcoholic extraction is treated with a weak alkaline solution to dissolve proteids, and the extract thus obtained is mixed with the treated material from the alcoholic extract. Any dark coloured sugars contained in the extract may be bleached with sulphur dioxide or hydrogen peroxide. The substance, thus obtained may be used in the manufacture of margarine or artificial milk.

Abstract: 979,493. Electric selective signalling systems; counters. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. May 31,1961 [June 1, 1960], No. 19681/61. Headings G4D and G4H. [Also in Division G3] A device for stopping a rotating shaft in accordance with a perforated sheet programme comprises a cyclometer type revolution counter each of whose digit wheels acts as a selector switch. A precision switch operates with the least significant digit wheel to connect into the control circuit a further wheel rotating with the least significant digit wheel to enable a fraction of rotation of the least significant wheel to be taken into account. The programmed sheet is wrapped around a programme drum 12, having five conductive cylinders, one per decade, each having ten contact fingers 17 for reading the programmed, these fingers being connected to ten contacts closed in turn by the appropriate digit wheel of the revolution counter. The common wiper contact is connectedto the previous decade cylinder,Fig.3 not shown. The shaft, not shown, and the counter thus rotates until each wiper is on a contact marked by those fingers 17 selected by the programme. The output from the selected contact on the last digit wheel 11 of the counter (corresponding to tenths of a revolution) is connected over a precision rotary switch 13 to actuate a relay 14 which connects into circuit a further wheel 15 which carries ten cams, each of which closes ten contacts in sequence per revolution; thus, there are ten shaft positions which agree with the number programmed at the 0. 01 zone of programme 16, but the wheel 15 is only energized by relay 14 during the correct tenth of a revolution; thus the shaft stopping signal appears at 18 at a hundredth of a revolution determined by the programme and wheel 15. In a modification, Fig. 2 not shown, the programme is in a binary-decimal form and the counter is provided with sets of four changeover contacts instead of ten simple contacts.
