Abstract: A plant for the production of stacks of intermeshed blanks of paper, cellse or the like folded together in a zig-zag fashion, in which two supply rolls are associated with the plant. Material webs on the rolls correspond to a multiple of two, four, or six or a higher even-numbered multiple of the width of the individual blanks. Longitudinal cutting stations divide the material webs into partial webs. The partial webs are opposite each other and run toward each other in the longitudinal direction of the webs and are fed to a stack-producing unit from two opposing sides. The stack-producing units of partial webs adjacent to each other are arranged in displaced relation to each other.

Abstract: An improved hunting device for use as a jacket and to assist in hauling game from the woods is disclosed. The device of the present invention is constructed by measuring and cutting a rectangular piece of carpet or other flexible, foldable material. The material is sized to fit the upper body down to waist level and an opening is cut in the center of the material to receive the head of the hunter. A length of rope is attached to one of the short sides of the rectangular material adjacent both outer ends thereof and the rope then extends on the underside of the material adjacent both long sides of the material along the length thereof. The rope then passes through a hole adjacent each outer end of the other short side of the material to the outerside of the material and a securing hook is attached to each of the two ends of the rope. In use, the hunter passes his arms between the rope and material on each long side thereof and inserts his head through the center opening.

Abstract: A liquid crystal information storage device comprising a layer of material containing a side chain polymeric liquid crystal. At least a part of the material is heated from a viscous state above its glass transition temperature, to a fluid region in which the liquid crystalline material can readily undergo field-induced alignment. The material is addressed in this fluid region so as to achieve the selective variation in texture and orientation of molecules within the material and so record information, and the material is subsequently cooled and returned to its viscous state whereupon the information is retained.

Abstract: A pump for dispensing liquid via a syringe has a chamber in which a hollow cylinder is mounted. The cylinder is connected to the chamber via a first normally closed check valve. A hollow plunger reciprocates in the cylinder is connected thereto via a second normally closed check valve. A charge of liquid is placed in the hollow plunger. On the out-stroke of the piston, the liquid in the piston is sucked through the second normally closed check valve into the cylinder and on the in-stroke of the plunger the liquid is forced through the first normally closed check valve into the chamber wherein it is maintained under pressure created by the pumping action of the plunger. An outlet tube leads from the lower part of the chamber to a syringe and an normally closed pinch valve in the syringe is manually operable to permit liquid under pressure to be squirted from the syringe.

Abstract: A method is described for indexing a polyfoam block in which a metal field shaping block is cast to both the cutting tray of a hot wire cutting system and the treatment tray of a radiation therapy treatment machine. The cast metal field shaping block is automatically correctly oriented for treatment. A cooling tray for cooling the casting is also described.

Abstract: A hot wire cutting system for cutting a pattern shape in a block of polyfoam for use as a casting mold for a metal shielding block to be used in radiotherapy treatments is described. The system provides proportioned current responsive to deflection of the hot cutter wire in order to cancel the deflection and maintain the wire in its optimal central cutting position. The hot cutter-wire preferably passes through a field which provides fine vibratory motion of the cutting wire allowing use of lower wire temperatures to effect the cutting. The system may include optical means for determining the accuracy of the profile cut in the polyfoam block.

Abstract: A device for testing the efficiency of autoclaves of the type used in hospitals for steam sterilizing porous loads such as surgical dressings, and particularly for detecting the presence of air in such a system, comprising first and second porous masses (10, 11) of a substantially man-made material such as spun bonded polypropylene, superimposed so as to sandwich therebetween an indicator sheet (12) and a pair of porous and absorbent sheets (12a). This assembly is held firmly together within a perforated stainless steel box (13) having a closable lid (14). For the test the whole device is placed in a steam sterilizer under normal working conditions. Subsequently, the test device is removed and the indicator sheet (12) inspected, any color variation across the sheet providing an indication of incomplete sterilizing conditions.

Abstract: Material discharge apparatus including in one embodiment, a material receiving hopper which can be attached to the outlet of a silo and carrying a conical closure member which is mounted on an actuating cylinder to be raised and lowered with respect to the wall of the receiving hopper thus to determine and control the flow of material from the silo into and through the receiving hopper. A vibrating motor is also provided, being adapted to impose a vertical oscillatory motion on the closure member thus to promote the free flow of material through the annular opening created when the closure member is in its raised position, the height of the member in this position being determined, for example, by a control device whereby the rate of flow of material can be varied.

Abstract: A packingless gate valve is disclosed which includes a housing having opposed similar housing halves with resilient sleeve units which compressibly engage each other in the valve open condition and engage opposite sides of the gate in the valve closed condition. Each sleeve unit has a flange on the inner and outer axial ends, with the flanges extending radially outwardly from the sleeve body. An encircling thin stiffening ring of harder material is bonded to the axially outer surface of the flange on the inner end of each sleeve, each stiffening ring being shaped with a right angle bend so as to provide both axially and radially facing surfaces for each sleeve body. The particular configuration and position of the stiffener rings has been found to function advantageously in preventing the pliable sleeve material from following the gate as it penetrates between the opposed sleeve units.

Abstract: Access equipment including a vehicle (10) on which stands a mast (14) movable between horizontal and vertical positions and mounted for rotation about an axis (13). The mast is telescopically extendible and carries a pivoted boom (17) which is also telescopically extendible and carries a further boom (19) with a working platform (20) thereon. Booms (17, 19) can operate only when the mast (14) is vertical. A cable system maintains platform (20) level for all positions of booms (17, 19) and at least two sets of conduits extend from the vehicle (10) to the platform (20). A take-up system for maintaining the conduits taut is located in casing (54) attached to mast (14) and includes sets of rollers (61 to 69) for supporting the conduits around curved paths and preventing them from becoming entangled.

Abstract: A method of manufacturing extruded pipes where plasticized material, for example plastic material, is advanced to an extrusion nozzle comprising a circular gap (2). The method is especially characterized in that the material is transported axially in said gap (2) while material is moved, for example rotated, in the circumferential direction of the gap (2) so that the material at least partially is caused to assume an orientation deviating from the axial direction, whereby a non-axial orientation will prevail in the extruded pipe (3) and increase the strength. The invention also relates to an apparatus for carrying out the method.
