Title: Method and apparatus for producing a plastic sleeve
Inventor: GOLDEN LEONARD WINKFIELD
IPC: B29C53/42
Filed: 1982-09-04
Abstract: A method and apparatus for making a tubular sleeve of thermo-plastic material wherein a strip of sheet stock 15 is fed to a rotatable turret 11 having a plurality of drivable rotatable mandrels 12 thereon. The strip is severed by a knife 19 into individual rectangular blanks, each having a leading edge and a trailing edge, and each blank is formed into a cylindrical shaped sleeve wrapped around a mandrel 12 with the trailing edge overlapping the exterior of the leading edge of the blank, hot gas being applied by a blower F to both surfaces of the trailing edge. The mandrels are moved past a sealing station S and a plurality of seal bars 21 are rotated so they move successively in an arcuate path generally tangentially to the path of the blank to bring the sealing surface of each bar into engagement with the overlapped edges and apply radial pressure thereto to fuse the edges together and form a seam. Each bar 21 has an arcuate concave contacting surface and is formed with radially extending portions 31 a, 31 b, Fig. 5, of stepped configuration to apply a greater pressure to one part of the seam than the other. A solvent spray may be fed through the blower F or separately. <IMAGE>

Patent GB-2106434-A (GB)
Title: Precision casting of metals
Inventor: WHEELDON JEFFREY KEITH
IPC: B22C9/06
Filed: 1982-09-23
Abstract: Die-casting or injection moulding dies are usually expensive due to the need for skilled machining and hand finishing. The invention enables castings of high precision to be produced at comparatively low cost. Resin-coated granular refractory material is packed against a model of the desired casting, for example a plaster cast, and heated, preferably under pressure, to cure the resin to form a mould against which metal can be cast e.g. to produce a cast iron die for die-casting or plastics injection moulding. The granular material is preferably packed against the model in layers, each of a different grain size, and the packing may be effected around tubes which will serve for conducting cooling fluid during the metal casting. A plurality of moulds may be made, each corresponding with a different part of the desired surface, and the different parts cast by the moulds being assembled to form the casting die e.g. assembled under clamping pressure and heated to remove distortion. <IMAGE>

Title: Improvements in and relating to liquid applicators
Inventor: JOICE DAVID CHRISTOPHER
IPC: A01M21/04
Filed: 1982-10-25
Abstract: An applicator for applying liquids to plants comprises an elongate tubular handle (10) with a foot at one end, the interior of the foot being in fluid communication with the interior of the handle. A length of water absorbent material, e.g. rope extends around the exterior of the foot and passes in a sealing manner to the interior. A bottle (20) of liquid to be applied is screwed to the other end of the handle. Upon such attachment tubular piercing member (50) of the handle punctures a closure member (56) of the bottle, permitting liquid to pass from the bottle to the interior of the handle and into the foot. The absorbent material becomes wetted with the liquid, producing a film of liquid which can be applied to plants as desired.   <IMAGE>

Title: Position and/or dimensions of objects
Inventor: RICHTER BRUNO
IPC: G01B11/08
Filed: 1983-09-28
Abstract: A measuring apparatus comprises a light source 1 which, by means of beam splitters 3 and mirrors 4, produces a plurality of parallel focussed beams 5 all lying in a common plane. Beams 5 are directed onto a rotating mirror 7 the axis of rotation 6 of which lies in the plane of beams 5. The beams are reflected from mirror 7 onto a collimating lens 9 so that they execute a parallel sideways displacement scanning motion a measuring field 11 in which an object 10 is placed. The beams after passing through measuring field 11 are deflected by a focussing device 13 onto individual detectors 14, 15, 16 and 17. The period of obscuration of the beams as detected by the detectors is a measure of the dimension of object 10 in the direction of scanning of the beams in field 11. The outputs of the detectors are fed to a combining device 18 for evaluation. Device 18 may select that beam for providing the measurement signal which has the least time period of obscuration. <IMAGE>

Title: Linked conveyors
Inventor: WIESENBAUER HUBERT
IPC: B65G41/00
Filed: 1984-10-09
Abstract: The invention refers to a device for coupling and steering two successive conveyor sections (1) which each have a wheeled chassis. Each conveyor section (1) is supported with its discharge end (2) on the receiving end (3) of the subsequent conveyor section (1). The individual conveyor sections each have only one chassis comprising wheels (5, 6) and this chassis is arranged at one end, namely at the receiving end (3) of the conveyor section. The conveyor sections are coupled one with the other for being swivelled around a vertical axis (4). A holding means is swivellably connected with the receiving end (3) of the succeeding conveyor section (1) for being swivelled around a vertical axis (4), with which holding means the discharge end (2) of the preceding conveyor section is connected in a tension-proof manner. The holding means is connected with steering levers (8) for the wheels (5, 6) by means of connecting rods, so that the wheels (5, 6) can be steered by and in accordance with the relative swivelling movement of both conveyor sections (Figure 1), out of alignment, the inside and outside wheels being steered to predetermined different extents as governed by the linkage. <IMAGE>

Title: Circuit interrupters
Inventor: GONEK STANISLAW MIECZYSLAW
IPC: H01H33/18
Filed: 1985-01-04
Abstract: An electrical circuit interrupter employing axial rotation of arcs includes a fixed contact 1, an electromagnetic assembly 2 and a moveable contact assembly 3 co-axially aligned with each other. The contact assembly 3 includes first electrical contact means 20 to enable a main current path to be established and second electrical contact means 15 for slidably engaging the electromagnet assembly 2 to enable an auxiliary current path to be established. In operation movement of the contact assembly 3 into the open position causes the auxiliary current path to be established so that an arc is drawn between the contact assembly 3 and the fixed contact 1 to facilitate axial rotation of the arc and ultimately extinguishing of the arc. Movement into the closed position causes the contact assembly 3 to initially establish the auxiliary current path and to effect engagement of the first electrical contact means 20 with the fixed contact 1 thereby establishing the main current path in supremacy to the auxiliary current path. <IMAGE>
