Abstract: In can manufacturing apparatus there is provided an overhead magnetic conveyor for transferring cans from a conveyor upon which they are coated to a conveyor upon which the cans are dried. To remove excess coating material which tends to form a bead around the lower most edge of a can, a bath of coating material solvent is disposed adjacent to the transfer conveyor and has within it an endless belt conveyor to which cans on the overhead conveyor are caused to fall and from which those cans are subsequently returned to the overhead conveyor. The upper, can carrying course of the endless belt conveyor is disposed at a predetermined depth below the surface of solvent within the cans so that excess material accumulating on the lower portions of the cans in the coating region is removed prior to entry of the cans into the drying oven.

Abstract: A modular assembly of reciprocating electric generators with respective movable floats and a common submerged damper plate and buoyancy chamber produces electricity from wave motion on a body of water.

Abstract: A retractable ballpoint pen has a body and a point secured to a flexible tubular ink reservoir. The ink reservoir is secured to a rotatable element within the body, movement of which element causes the pen to be retracted and projected and during that movement the reservoir follows a generally circular path.

Abstract: An electronic musical keyboard instrument has a unit separate from the main console and having switching means for performing the function of at least some of the keys and stops of the console that unit being adapted to be operated by a handicapped person.

Abstract: The invention relates to a press, especially for pressing straw material into briquets. The press has a number of press chambers open at either end and a number of pistons, the press chambers and pistons being connected to guiding means and driving means so that the pistons are moved inwards and outwards in relation to the press chambers at one end thereof for introducing press material in portions, pressing the press material and moving it to the other end of the press chambers where it is delivered. The pistons have a smaller outer extent than the inner extent of the press chambers in the engagement region of the pistons. Hereby some advantages are obtained.

Abstract: A bulkhead for a swimming pool has a simple, lightweight frame, improved movability within the pool and means for suppressing the ill effects of waves produced by a swimmer nearing the bulkhead.

Abstract: A mincing machine, especially a meat mincing machine, of the type which has a rotatable knife disc 1 in front of a disc 2 with holes, and means for feeding mincing material including bone fragments to the knife disc and pressing out minced material minus the bone fragments through the disc having apertures, said knife disc and disc with apertures being arranged in a housing, characterized in that the housing in the region adjacent the knife disc has at least one recess constructed and arranged to receive and relinquish said bone fragments contained in the meat.

Abstract: A fabric composed of a fleece or backing of fibrous material with parallel rows of single thread, sewn-knitted, run resistant, stitches superimposed thereon; a method of making the fabric and a warp knitting machine which is suitable for the production of the sewn-knitted fabric. The fabric can advantageously be used for outer garments, household or space textiles.

Abstract: An apparatus for cutting and conveying material, comprising a container with an insertion aperture, cutting and conveying means and outlet means, the apparatus having above the bottom of the container cutting means for cutting grooves in the material and conveying means for conveying the material between the grooves.

Abstract: A piston-type safety lock device, of the type comprising a cylindrical rotor journalled in a cavity of a stator. Said rotor contains a plurality of radially slidable pistons cooperating at their inner end with the notches of a key for bringing their other end flush with the periphery of said rotor. Said other end bears against the inner surface of the cavity in which the rotor is journalled and, for one angular position of the rotor, against pistons slidable in the stator and elastically biased toward the rotor. Said pistons of the stator and rotor are flat blanked members. Said pistons are disposed respectively in a single slot of the stator and in a single slot of the rotor and have rectilinear and parallel lateral edges which are in contact with the lateral edge of an adjacent piston or the end of said slot.

Abstract: A fabric is coated with a composition which comprises a thermoplastic polyurethane and a sulfone having the following general formula ##STR1## wherein R represents --H, --CH.sub.3, --C.sub.2 H.sub.5, --C.sub.3 H.sub.7 OH, --CH.sub.2 CH.sub.2 Br or --(CH.sub.2 CH.sub.2 O).sub.n H and n is a integer of 1 to 5, and preferably a polyisocyanate as a cross-linking agent.

Abstract: A system for handling two liquid streams comprises an hydraulic circuit including a pair of receptacles each provided with movable partition means dividing it into first and second chambers. Rod means extending through a first chamber of each receptacle connects the partition means and is effective to cause reciprocation of one partition means to be repeated by the other so that as the first chamber of one receptacle is expanded, the first chamber of the other receptacle is contracted. A quantity of the first liquid is delivered alternately to the first and second chambers of one receptacle as those chambers expand. As those chambers contract first liquid is passed through conduit means from the first and second chambers of said one receptacle to the first and second chambers, respectively, of said other receptacle.

Abstract: Apparatus for clamping a thread in a reeling machine having a reeling cage which is rotatably mounted on the machine frame and comprises bars extending parallel to the axis of rotation thereof, and a thread laying device which is displaceable on the machine frame, for changing laying of an incoming thread in rope form on the bars of the reeling cage, wherein at least one bar of the reeling cage is provided with a strip-like-first brush for clamping a thread between its bristles, and a thread receiver which is displaceable backwards and forwards on the machine frame transversely to the axis of rotation of the reeling cage supports a similar second brush, and wherein a certain thread length can be pulled out by means of an arm which is pivotally mounted on the thread receiver between the second brush advanced together with the thread receiver and the thread laying device, which thread length, after the thread has been severed, the finished rope has been removed and the thread receiver has returned, hangs in the

Abstract: A fabric is coated with a composition which comprises a thermoplastic polyurethane and 2,2-bis(4-hydroxy-3,5-dibromophenyl)propane derivative having the following general formula ##STR1## wherein each n1 and n2 represents zero or a positive integer and n1 + n2 is zero or one of the integers from 1 to 8, and preferably a polyisocyanate as a cross-linking agent.
