Abstract: Plastic sheet material used for forming box blanks are provided with soft, bendable score lines by applying frictional heat through rapid vibration. The sheet material is clamped under high pressure between a resilient make-ready and a scoring tool, and is subjected to the vibratory action which generates frictional heat sufficient to melt the plastic material at the engaged interface, thereby forming a score line along which the sheet material may be bent to form an assembled box. A completed box blank may be formed in a single operational step, by cutting the box, impressing the score lines, and impressing embossments, if required, simultaneously in a single operational cycle of seconds duration.

Abstract: A cutter box and clamp assembly is provided in a spreading machine for laying fabric or other sheet material on a cutting table, for the purpose of cutting off the sheet material at the end of each layer which is spread. The assembly includes a housing mounted on the spreading machine carriage, a cutter frame movably mounted in the housing, a cutter disc rotatably mounted on the cutter frame and drive apparatus for moving the cutter frame and the cutter disc, carried thereby, from one end of the housing to the other. A spring-mounted pressure bar bears against the edge of the cutter disc and the sheet material is fed between the cutter disc and the pressure bar. A clamp member operates to clamp the sheet material to the pressure bar prior to operation of the cutter disc. When the cutter frame is driven in a cutting stroke, the cutter disc rolls along the pressure bar and traverses the sheet material forcing its way through the material to perform a scoring cut and causing the material to part.

Abstract: An apparatus is disclosed for mechanically decapitating fish, in which fish lying on one of their sides are conveyed transversely and decapitated by a wedge-shaped cut by means of a decapitating tool. In order to perform an exact symmetrical and economical decapitating cut independently of the respective size of the fish to be processed the decapitating tool is mounted pivotably about a pivot axle extending in the plane of symmetry of the same and parallel to the conveying direction of the fish. The adaptation proceeds automatically through a pair of centrally synchronized feeler rails which are borne on the housing carrying the knives of the beheading tool.

Abstract: A multiple barrel syringe for selective delivery of a plurality of fluids through a single needle is adapted to be loaded with each of said fluids through the needle thereof. The syringe body includes a pair of fluid-retaining bores, each containing a plunger and each communicating with the single needle through restrictive conduits in which respective flexible sealing valves are interposed. As each plunger is depressed, the respective valve is depressed and distorts under pressure of the fluid, allowing the fluid to flow to the needle. For filling each bore through the needle, a plunger is manually depressed to compress and distort the respective valve, enabling fluid to flow from a container through the needle and through the unobstructed conduit to the selected bore in response to raising of the plunger.

Abstract: A multiple barrel syringe for selective delivery of fluids which comprises a body having a pair of bores each containing a plunger and each terminating in a smaller sized conduit for receiving fluid from the bores. Connected to the body is a movable member having a single conduit or passage and a needle mounted on the member and communicating with the bore. The movable member may be manually actuated to bring its single conduit into communication with a selected bore conduit for providing passage of fluid from the selected bore to the needle. The movable member may then be moved to another position to bring the needle into communication with the other bore. Sealing means are provided on the movable member to avoid leakage and feedback of fluid from or to the bore not dispensing fluid.

Abstract: A ventilated animal cage rack has a hollow housing divided into a plurality of horizontally-disposed shelf compartments separated from each other by partition walls and having front open ends normally closed off by transparent doors which isolate the interiors of the shelf compartments from each other and from the interior of the room containing the cage rack. Each shelf compartment is sized to contain a row of horizontally-spaced animal cages having open top ends and closed bottom ends, with the open top ends spaced well below the ceiling of the shelf compartment. A low pressure air plenum extends vertically along one side of the cage rack and communicates with one side of each of said shelf compartments, the other sides of which contain air inlet openings communicating with the room interior, thereby providing a low-pressure negative air flow along the top open ends of the contained animal cages to said air plenum and then to a room exhaust system.

Abstract: There is disclosed a mechanical fish filleting process, whose use with decapitated fish, particularly, those of approximately circular cross section, enables a substantial reduction in the manual trimming which is caused by falsely positioned cuts. A sequence of cuts is proposed which permits a more exact guiding and thus also alignment of the fish. The method comprises the following cut sequence: belly filleting cut, rib cut, severing cut to separate the lateral vertebral appendages and/or ribs from the back bone, back filleting cut guided from the belly to the vicinity of the fin holders of the dorsal fins, pinbone cut and back severing cut on both sides of the dorsal fins. The dorsal fins are so guided that they are reliably introduced between the back severing knives so that the fillets can be cut free from the fins or their remains.

Abstract: A doll with closing eyes includes a head having a front fabric panel which is mounted superimposed on a base fabric panel. The front panel includes a pair of cut-out portions which resemble eye orbits. An eye panel which has indicia depicting a pair of open eyes and a pair of closed eyes is slideably disposed between the front and base panels. A ribbon is attached to the eye panel and passes through slots formed in the front fabric panel enabling a child to pull on the ribbon and move the eye panel so that either the pair of closed eyes or the pair of open eyes is visible through the cut-out portions in the front fabric panel.

Abstract: A ventilated article of footwear, such as a shoe, is provided with an outer sole of deformable material having a raised peripheral portion of enlarged thickness surrounding the entire periphery thereof. An inner sole of non-deformable material is mounted above the outer sole in normally spaced relation therefrom to define an air chamber between the soles. The inner sole is perforated with a plurality of apertures providing communication between the air chamber and the interior of the shoe. A compressible supporting material is located in the air chamber between the inner and outer soles and normally biases the deformable outer sole away from the inner sole to provide a relatively deep air chamber. When the wearer of the shoe applies his weight upon the outer sole, the latter deforms upwardly compressing the compressible supporting material and reducing the depth of the air chamber.

The cutter box assembly includes a housing mounted on the spreading machine carriage, a cutter frame movably mounted in the housing, a cutter disk rotatably mounted on said cutter frame, and drive apparatus for moving the cutter frame, and the cutter disk carried thereby, from one end of the housing to the other, when the machine carriage reaches the limit of its travel along the table. A spring-mounted pressure bar bears against the edge of the cutter disk, and the sheet material is fed between the cutter disk and the pressure bar. When the cutter frame is driven in a cutting stroke, the cutter disk rolls along said pressure bar and traverses the sheet material forcing its way through the material to perform a scoring cut and causing the material to part.

Abstract: The invention concerns a needle bar draw frame or gill box with a needle field or gilling area of needle bars carried by chains. With the aim of attaining the usual performances in respect of speed and drawing ratio at the same quality also in the case of voluminous short-staple slivers with draw frames operating with an upper and a lower needle field, control means engaging from above into the needle field are used in a draw frame provided merely with a lower needle field. These control means are constructed as bristle-like holding down devices which are arranged particularly immediately upstream of a pair of drawing rollers and possibly shortly downstream of a pair of entry rollers, while the central region is controlled in the usual manner by a bar roller or bar chain.
