Abstract: 1278786 Coating with plastics materials W. & J. TOD Ltd 22 Aug 1969 [22 Nov 1968] 55450/68 Heading B2E [Also in Divisions B5 and D1] A curable resinous plastics material is applied to a reinforcing material for bonding of the reinforcing material with the plastics material by (a) providing a first quantity of the curable resinous plastics material mixed with a catalyst and having a pot life of at least one day (b) providing a second quantity of the curable resinous plastics material mixed with an accelerator and having a pot life of at least one week, (c) applying both mixtures to respective areas of opposed faces of a sheet of reinforcing material having interstices from one face to the other in such a manner that substantially no intermingling of the mixtures takes place and (d) acting physically on the treated reinforcing material to cause the mixtures to become impregnated in the reinforcing material and mixed together such that curing of the resin occurs in the reinforcing material. The reinforcing material may be a woven fabric, e.g. of glass fibres, the resin may be a polyester containing a filler, the catalyst may be benzoyl peroxide and the accelerator may be dimethyl aniline. The two mixtures may be applied one to each surface of the reinforcing material by means of dispensing troughs fed from hoppers and the reinforcing material then subjected to rolling preferably on the face of a mould or former to effect intermingling of the mixtures. The reinforcing material may be transported by means of rollers at the side edges that are not treated with the mixtures to prevent contamination of the rollers. Estimation of when adequate impregnation and mixing have occured may be facilitated by making the two mixtures of different colours. Boat hulls may be made from treated glass-fibre reinforcing materials.

[Also in Division A3] A method of producing a breast cup for a brassiere comprises forming stretchable thermoplastic sheet 3 around a curved edge 2 of a substantially flat former 1, setting the sheet material in that formed condition by heating, and after removal from the former opening the formed material into a cup shape by separating the adjacent edges 6. Unwanted material is removed by cutting both layers along the dotted line 5. The material on the former may be heated in an autoclave by means of high pressure steam. In a second embodiment, the former (1, Fig. 3, not shown) may be shaped to form two or more cups, or the front portion of a brassiere (Fig. 4, not shown), simultaneously from a single piece of material which may be cut to separate the cups, or front portion of the brassiere from the unwanted material. In a third embodiment, a plurality of front parts of brassieres may be formed by stretching a sheet of the thermoplastic material around spaced apart, and substantially flat formers 23, each having two adjacent curved edge portions 24 by means of further substantially flat spaced apart formers 20, 17 which are interdigitated with the first mentioned formers 23, setting the material in this condition by heating, and finally cutting away unwanted material. The alternate ones 20 of said further formers are each shaped to define the lower edge of a brassiere front, and the remaining ones 17 of said further formers are each shaped to define the upper edge of a brassiere front. Retractable cutting blades may be incorporated in the boards 17, 20 so as to separate the pairs of cups after heat setting. In a fourth embodiment, two adjacent ones of said further formers 29 may be inserted into one space between two adjacent ones of the first mentioned formers 30 to define the lower edges of two brassiere fronts, and the next two adjacent ones of said further formers 28 are inserted into the space adjacent to said one space between two adjacent ones of the first mentioned formers to define the upper edges of two brassiere fronts. In addition, auxiliary formers 34, 35 are positioned between pairs of said first mentioned formers, so that they are interdigitable with the two adjacent ones of said further formers, and are inserted into said spacers between formers 28 and 29. The stretchable thermoplastic sheet material employed is either a woven or knitted fabric, or a non-woven web formed wholly or partly from thermoplastic fibres, or foamed thermoplastic sheet material, or a plain warp knitted nylon fabric, or a plain warp knitted nylon material laminated to a non-woven web of polyester fibres. Bikini tops, and the breast supporting parts of combination garments worn as outer wear or underwear such as bra dresses, bra-nightdresses, bra-slips and corselettes may be manufactured by the method described.

Title: Carburettor assemblies for precombustion chamber internal combustion engines
IPC: F02M1/02
Filed: 1973-12-14
Abstract: 1458518 Spray carburetters HONDA GIKEN KOGYO KK 14 Dec 1973 [30 July 1973] 58112/73 Heading F1H A carburetter assembly comprises a main passage for supplying a first mixture to a main combustion chamber of an engine, an auxiliary passage for supplying a second mixture to an auxiliary combustion chamber of the engine, each passage having a throttle valve mounted on a rotatable shaft, means 12, 13, 14 for transmitting turning movements between the shafts, a choke valve 16 mounted in the primary passage upstream of the primary throttle valve 5, means for actuating the choke valve 16 and means for moving the primary throttle valve in response to operation of the choke valve actuating means, whereby actuation of the choke valve brings about movement of both the throttle valves 5 and 9. Choke valve 16 is unbalance mounted on shaft 17 which projects through stationary sleeve 19 and carries an angled lever 43. Choke operating knob 32, through cable 23 rotates actuator 20 in a clockwise direction, as seen in Fig. 1, against torsion spring 25, when the cable is pulled. Actuator 20 runs on sleeve 19 and through torsion spring 44 turns crank member 37 which has an arm 41 which engages lever 43 and turns choke valve 16 in a closing direction. Crank member 37 is also connected by rod 40 to vacuum motor 64, which turns the choke valve in the opening direction when the engine is running under its own power and the intake manifold vacuum acting in chamber 67 overcomes spring 72. The amount by which the choke valve is turned in the opening direction is determined by limiter member 52 which is rotatably mounted on pin 53 and includes a follower member 51 which also runs on cam surface 49. As limiter member 52 is rotated anti-clockwise by the cam surface, a stop member 54 moves to a position which is dependent on the extent to which the actuator 20 has been turned by using the operators control knob 32. Stop member 54 is engaged by projection 55 on crank member 37 when this is rotated by movement of the rod 40. Actuator 20 also includes a cam surface 49 which engages a cam follower 57 on lever 58 and rotates the lever about pivot 59 so that end 60 of the lever engages tab 61 on lever 7 and rotates main throttle valve shaft 6. Link 14 transmits the movement to lever 13 and thus rotates auxiliary throttle valve 9. In a modification, Fig. 6, (not shown), the choke valve is moved to the closed position by a conventional bimetal coiled spring 92, when the accelerator pedal is fully depressed prior to starting the engine. The linked throttle valves open to an extent determined by a stepped cam 107. The limiter member 52 is replaced by a second stepped cam 102 which is rotated to a position dependent on the ambient temperature by a bi-metal spring.
