Abstract: 336,869. Berthiez, C. Dec. 16, 1929. Lathes. - In a vertical - spindle lathe having a single standard d supporting a fixed tool-carrying arm c, the face-plate a is rotatably mounted on a saddle b which is horizontally adjustable on the bed e in a direction parallel to the arm c so as to increase the radius of action of the lathe, the tool-holder being correspondingly displaced along the arm c before the turning operation is commenced. The saddle slides in one or more grooves in the bed and on a V-sectional rail and is traversed by a nut thereon engaging a screwed spindle e<3> which may be rotated by hand or by a small electric motor. The face-plate is rotated by a bevel gear on a shaft f movable axially with the saddle and driven by a splined gear g and belt pulleys (not shown). The radius of action of the lathe may be further increased by securing an auxiliary bed, for receiving the face-plate, to the bed e and replacing the shaft f by a longer shaft. After adjustment on the bed the face-plate is secured thereto by screws or clamps.

Abstract: 1,056,267. Air-cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. Oct. 18, 1963 [Oct. 18, 1962], No. 39546/62. Heading B7K. A flexible skirt which at least partly contains the cushion of an air-cushion vehicle is attached to the lower part of the vehicle and comprises a thin-walled flexible member which, in cross-section normal to the cushion periphery extends from a first edge outwardly away from the cushion, then downwardly and inwardly, and then upwardly to a second edge, to present a convex surface towards the supporting surface below the vehicle. In Fig. 6, the first edge 3 is anchored to the vehicle 29 at 20, and the second edge 4 is tied to an anchorage 6 by cords 5. To prevent the accumulation of foreign matter in the skirt, the cords 5 may be replaced by a diaphragm forming a closed space with the skirt, or a diaphragm may extend from the edge 4 to an anchorage near the edge 3. The skirt may then be inflated by the cushion air or gas supply, or from an independent controllable source. Drain holes may be provided in the surface 9. The edge 3 may be located at the periphery of the vehicle, the member 2 extending initially upwardly and outwardly, or as shown, may be inboard of the periphery, or an extension 22 thereof, so that when the clearance between the lower surface 7 of the vehicle and the supporting surface 10 lessens, and the skirt deflects upwardly, its area of contact with the vehicle increases to produce a restoring force on the vehicle to give stability in pitch, roll, and heave. This stability may be varied by movement of extension 22 by jack 24. The outer part of surface 7 may be curved. The skirt may be reinforced by inflatable tubes, each located in a vertical plane, the inflation pressure being the same as or different from the cushion or skirt pressure. Rubber, plastic, or metal strips may be used as reinforcement. A plurality of such skirts may be arranged in vertical sequence, or the skirt may be attached to the bottom surface of a rigid, flexibly attached, or flexible skirt depending from the vehicle, Fig. 15 (not shown). The anchorage points 6 may be movable inboard or outboard by control linkages to vary the centre of pressure of the cushion to provide pitch-and-roll moments, Fig. 16 (not shown). Such skirts may be used to partition cushions. One or more discontinuities may be present in the skirt cross-section, to affect the deflection characteristics of the skirt, for example, rubber beads may be attached to the exterior of the convex surface 9, the beads extending peripherally of the skirt.

Title: Process and apparatus for the production of mouldings or extrusions having a cellular structure from thermoplastic synthetic materials
IPC: B29C48/03

Abstract: 1,018,178. Moulding expanded synthetic resins. T. ENGEL. Oct. 1, 1964 [Nov. 29, 1963], No. 40013/64. Heading B5A. In a process of moulding expanded thermo - plastic synthetic resin, e.g. polythene, the resin is plasticized by a screw 2 and a blowing agent, e.g. ammonium carbonate, is introduced into cylinder 1 by means of a screw 3, the blowing agent being stored in a reservoir 4, where it is subjected to air or other gas pressure. Heat and pressure conditions within the cylinder are maintained such that although the resin remains liquefied, expansion does not occur until the resin leaves nozzle 6, and according to the invention, the cooling that then takes place results in the formation of an extensible outer skin within which the expansion occurs. The reservoir 4 may contain a quantity of powdered thermoplastic material, dyestuffs, lubricants and other additives, such as stabilizers, as well as the expanding agent, and the use of a gas under pressure to act as expanding agent is also considered. In the embodiment shown, extrudate is fed in turn to open-ended moulds 10 mounted on a rotatable plate 9, the mould bottoms being covered by a fixed plate 18 provided with a gap so that the formed mouldings may be ejected by a pin 11. Extrusion is continuous, the motion of plate 9 from one position to the next cutting off the flow to a particular mould and determining together with the rate of extrusion the extent to which each mould is filled. In a modification, Fig. 3 (not shown), a cleaner cutoff of the extrudate is achieved by the provision of a reciprocable apertured thimble 12 positioned over nozzle 6, the base of the thimble being convex and sliding over the surface of plate 9 when the latter is rotated. Both cylinder 1 and moulds 10 may be cooled and the nozzle may extend into the mould and be withdrawn progressively therefrom, or the mould may be rotated during filling. In further embodiments (not shown) the resin is extruded either in the form of a strip from an elongated nozzle and is cut and shaped by mating cavity dies, or in the form of a tube which may be blow moulded. In a two-stage process the extrudate is cooled sufficiently to prevent complete expansion, expansion being completed subsequently by heating the resin in a mould. A rotary mixer may be provided between screw 2 and nozzle 6.

A device for spraying rectangular areas ineludes a stationary water inlet member 22 upon which is mounted a rotatable body 1, 4 provided with spray nozzles 8, 9 and housing a waterwheel 32, Fig. 2, having blades 33 surrounding a water distributing cap 23. The latter is rigidly secured to the member 22 and has outlet ports 24 whereby the issuing water drives the waterwheel mounted on a shaft 31 extending through a cover 6 secured to a flange 5 of the body. The water-wheel effects rotation of the body via a drive comprising a worm 34 keyed to the shaft 31 driving through gearing 35, 37 and 38 a coupling 40 on a shaft 39. The latter drives a toothed wheel 41 meshing with a stationary toothed wheel 25 secured to the member 22. The nozzles 8 and 9 are displaced 135 degrees in relation to each other and are automatically controlled so that when one is spraying to the corner of an area the other is spraying to the middle of a side. The nozzle 8 has an axiallymovable conical member 56 with an extension part 58, whereas the nozzle 9 has a similarly movable conical part 57 with a groove 59. When the member 56 is in its outermost position, the part 57 will be in its innermost position, i.e. the nozzle 8 will be spraying to the side of the area and nozzle 9 to the corner. Movement of the conical members is effected by means of an arm 52 pivoted on a pin 51 and carrying rods 54, 55 connected to the conical members. A pin 53 on the arm engages a groove 26 in the fixed wheel 25 and is guided therealong as the body rotates, so that the arm 52 moves about its pin and the rods 54, 55 move the conical members. Water from the ports 24 flows to the nozzles via an edge 12 and openings in the body.
