Title: Shoe making
IPC: A43D11/12
Filed: 1971-04-01
Abstract: 1401001 Boots &c SHOE & ALLIED TRADES RESEARCH ASSOCIATION 28 June 1972 [1 April 1971 12 May 1971] 8474/71 and 14502/71 Heading A3B Apparatus for preforming shoe uppers includes conveyor means 12 for conveying jigs 14 supporting the shoe upper material from a loading station 4, through a treatment station 6 for rendering the shoe upper material stretchable, and through a preforming station 8 to an unloading station 10. Each jig 14 (Fig. 3) consists of a pair of plates hinged together at 22, each of which has an aperture of slightly smaller size than the shoe upper blank 16, the plates being held apart by spacers 28, 30 which are slightly thinner than the blank 16. The blank 16 is located across the apertures by locating pins 24 on the lower plate which pass through apertures in the upper plate. The jigs 14 are carried through the apparatus by a pair of conveyer chains 32 (Fig. 1) which are driven from an electric motor (not shown) via clutch 40, belt 42 and sprockets 36. The jigs 14 are held on the chains 32 by pairs of rollers 44, each pair 44 being mounted on a member 46 which is urged downwardly with respect to guide rail 34 by springs (not shown). The conveyor 12 stops when the jigs 14 engage movable stops at the station 6 and 8. The treatment station 6 consists of chambers 54 mounted above and below the conveyor 12. In the case of leather uppers the chambers 54 form part of a mulling device and in the case of synthetic uppers, e.g. of poromeric material, the chambers 54 contain heaters, e.g. infra-red, R.F., or microwave heaters. The preforming station 8 (Figs. 1, 7) ineludes a box 56 mounted above the conveyor 12 and a box 60 mounted below the conveyor 12, the boxes being movable towards, and away from each other by a piston and cylinder device 102 which acts via bell cranks 96 and links 86, 90 and 98. When the boxes 56, 60 are in their closed positions as shown in Fig. 7 seals carried in flanges 56a, 60a engage the jig 14 in the region of the outer spacers 30. Each box 56, 60 also includes a clamping device 106 consisting of a plate 108 carrying adjustably mounted clamping pins. When the boxes 56, 60 are moved together the clamping pins engage both sides of the jig 14 so that the upper blank 16 is firmly gripped by the jig 14. The plates 108 are resiliently mounted in the boxes by elastomeric blocks 116 or by adjustable spring loaded devices (not shown). The lower box 60 contains a mould 62, e.g. of the type described in Specification 1300931, which can be raised by piston and cylinder device 70 acting via toggle linkage 78 and push rod 66. The outline shape of the mould 62 corresponds to the apertures in the jigs 14. During the moulding operation air under pressure may be applied to the upper box 56 and/ or vacuum may be applied to the lower box 60. The machine also includes a safety device (not shown) which stops the conveyor if the orientation of the jig 14 (e.g. for a right or left shoe) does not correspond to that of the mould 62.

Title: Production of polyurethane filaments and films
IPC: D01F6/72
Filed: 1963-03-04
Abstract: Polyurethane filaments and fibres are made by forming into a filament or film a solution of a polyurethane in a polar solvent therefor, which solution contains from 0.1 to 10% (preferably 0.5 to 3%) by weight, based on the solids content of the solution, of an organic compound containing at least two ethylene imide groups, stretching the filaments or films (e.g. 50 to 200%) and heat setting the filaments or films while they are in a stretched condition.  The polyurethane may have been produced by reacting a linear organic compound containing hydrogen atoms 2D1 which are reactive with -NCO groups with an organic diisocyanate and a chain extending agent having hydrogen atoms which are reactive with -NCO groups. The chain extending agent may be hydrazine, a diamine, water, a polyhydrazide, a bis-semicarbazide, a bis-carbazine-ester or a glycol. The compound containing ethylene imide groups may have been prepared by reacting an ethylene imine with an organic diisocyanate phosphoric acid, a carbonic acid ester, a cyanuric acid halide, a polycarbocylic acid or a polysulphonic acid. In an example, a polyester of adipic acid, ethylene glycol and 1,4-butanediol is reacted with diphenylmethane-4, 41-diisocyanate dissolved in chlorobenzene and the product is reacted with carbodihydrazide dissolved in dimethylformamide containing a small proportion of water. The solution is concentrated by fibre evaporation and to it is added a small proportion of hexamethylene-bis-NN-ethylene urea prepared from hexamethylene diisocyanate and ethylene imine. The solution is then dry spun into a spinning cabinet maintained at 210 DEG C. to form filaments which are stretched 100 to 150% and reeled on a bobbin which is maintained for 1 hour at 130 DEG C. so that the stretched filaments are heated set without their being allowed to shrink.  Specifications 798,209, 823,352, 917,450, 918,861, 939,196 and U.S.A. Specification 2,870,097 are referred to.

Patent GB-453859-A (GB)
Title: Improvements relating to the production of mercaptans and like organic sulphur compounds
Filed: 1935-03-19
Abstract: Organic sulphur compounds, particularly mercaptans, are prepared by the catalytic hydrogenation of aliphatic or cyclo-aliphatic carboxylic acids or their salts and esters in the presence of hydrogen sulphide and of a metal sulphide capable of accelerating a hydrogenation reaction.  The most effective catalysts are the sulphides of the first, sixth and eighth groups; if desired, the catalysts may be prepared in situ.  The reaction is preferably effected under a pressure of 50--500 atmospheres and at a temperature of 250--350 DEG  C.  Instead of hydrogen sulphide, materials which yield it under the conditions of the reaction may be employed, e.g. elementary sulphur, carbon disulphide and calcium, ammonium and sodium sulphides.  According to the examples: (1) a mixture of ethyl and propyl mercaptans is obtained by autoclaving ethyl propionate with hydrogen in the presence of molybdic acid and sulphur; (2) oleic acid is passed with hydrogen and hydrogen sulphide under pressure over clay impregnated with the oxides of molybdenum, tungsten, cobalt or copper, mercaptan products being obtained; (3) a mixture of octadecyl and octadecylene mercaptans results when oleic acid, hydrogen and carbon disulphide are passed under pressure over ammonium sulphomolybdate mounted on silica gel; (4) stearic acid (in toluene solution), naphthenic acid or olive oil is passed with hydrogen and carbon disulphide under pressure over the catalyst of (3) and yields sulphur-containing products; (5) mercaptans are formed by passing stearic acid with hydrogen and hydrogen sulphide under pressure over the catalyst of (3).  The use as catalyst of a polysulphide prepared by passing hydrogen sulphide through a concentrated ammoniacal solution of ammonium molybdate is referred to.

Abstract: 1,207,452. Glass rod manufacture. EASTMAN KODAK CO. 22 Feb., 1968 [23 Feb., 1967], No. 8696/68. Heading C1M. A process for the production of a glass rod comprises heating a flat spiral of cast glass to its flow point (viscosity 10<SP>5</SP> poises), unwinding the spiral into a linear rod while the glass is held at its flow point and then annealing and cooling the glass rod. A block of glass is cast as a rectangular prism and sawed in its major plane to form a spiral. A stainless steel ribbon 26 is interleaved with the spiral and fixed at the inner end on a roll bar 25 inserted through a hole cut at the centre of the spiral 14. The spiral is then placed with its outer end in a U-shaped channel 20, and is supported by the roll bar 25 resting on a pair of inclined supports 21 also bounding the spiral. The angle of inclination of the supports 21 may be adjustable. The arrangement is then placed in a furnace and heated until the viscosity of the glass is 10<SP>5</SP> poises. Tension is then applied to the outer end of steel ribbon 26 in a direction opposite to that faced by the outer end of spiral 14, and the spiral is unwound in the trough 20. The furnace is then cooled to anneal the glass and bring it to room temperature. The process may be used to produce rods of optical quality for lasers, the rods having a rectilinear shape. After forming they are ground and polished.

Title: Improvements in or relating to tipping-waggons
IPC: B60P1/24
Filed: 1922-03-27
Abstract: 199,794. Makins, A. D., and Rolbertson, A. March 27, 1922. Tip-wagons.-In a road or railway tipping- wagon having a body arranged to roll relatively to the frame during tipping, a body or tank of any desired shape, such as of V-section, is mounted on a cradle to provide a support of convex shape resting on the wagon frame. As sl-own, three bodies 13 are each mounted on a rails 11, 12 on the chassis 10, so that the bodies cradle comprising curved frames 14, 15, preferably of channel section, engaging transverse may be tipped independently of one another to either side of the wagon. The rails may have projections 16 engaging holes in the frames 14, 15 to prevent relative sliding movement during tipping. The frames 14, 15 may have any desired curvature and the ends of the rails may be curved upwards to reduce shock at the end of the tipping movement. Each body is adapted to be locked in its central position by a spring- actuated bolt 19 on a frame 20 engaging a socket in a plate 23 at the upper edge of the body, and the bolt may be withdrawn from the socket by pulling a handle 26 at either end of a cable 24 passing over a pulley 25 on the bolt. Each body is also retained in its normal position by chains 2 secured to the chassis and provided at their free ends with hooks 28 adapted to engage spring links 30 secured to the body, rings 29 locking the hooks in the engaged position in which the links 30 are stressed. On freeing the bolt 19 and one of the hooks 28, the spring-link 30 at the other side draws the body towards that side to initiate the tipping movement which may continue automatically. A chain or a jointed link 31 prevents undue tipping movement. A ridge-shaped member 32 may be mounted on a frame 20 over the space between two bodies so that material discharged thereon enters both bodies, and the rails 11, 12 or the frames 14, 15 are so shaped as to cause the bodies to tilt during tipping to clear the member 32. The bodies may be readily removed and the rails may be detachable from the chassis. Reference has been directed by the Comptroller to Specifications 28183/10,120,249, [Class 108 (i).

Title: Improvements in or relating to apparatus for controlling mass flow of air or other gases
Inventor: CARTER ANTHONY BASIL
IPC: G05D7/01
Filed: 1955-03-25
Abstract: 822,326. Automatic flow control systems. TEDDINGTON AIRCRAFT CONTROLS Ltd. June 25, 1956 [March 25, 1955], No. 8840/55. Class 38 (4). . The mass flow rate of gas (and in particular the mass flow of air to pressurized aircraft cabins) is controlled by deriving a differential pressure from a venturi in the flow conduit and transmitting the resultant force on a diaphragm 5 through a beam 7 pivoted at 8 to a lever 14 pivoted at 12, the distance of the point of application from pivot 12 being made proportional to the upstream pressure in the conduit by the use of a bellows 10 carrying the pivot 12 and responsive to this upstream pressure which is connected to the closed chamber 3. The torque applied to lever 14 is therefore proportional to the product of the upstream pressure and the pressure drop, and hence to the mass flow rate; this torque is opposed by that due to spring 13, which may be adjustable to enable the flow rate to be pre-set to a desired constant rate, and electrical contacts 15 control the operation of a flap valve in the conduit and hence the flow rate, to balance the torques. Instead of, or additionally to, adjustment of spring 13, to pre-set a desired flow rate, the pivot 8 may be adjustable in position by movement of its support 16 along a screw-thread 17 rotated by gearing 18 to vary the force transmitted by beam 7 to lever 14.
