Abstract: A portable firearm employs a frame and an upper mechanism having a bolt and a sliding hammer. A barrel assembly is supported on the frame and has an axis, a muzzle and a breech. The sear transversely straddles the barrel assembly and can project above its axis for restraining the hammer. A trigger mechanism employs a reciprocatable member coupled to the sear for selectively operating the sear automatically or semi-automatically. An intervening member is mounted to reciprocate transversely to the axis of the barrel assembly. This intervening member can retract upon the hammer moving against the intervening member. The intervening member is bifurcated to straddle and reciprocate transversely to the axis of the barrel assembly.

Abstract: A catalyst for the production of unsaturated aldehyde and unsaturated carboxylic acid by the vapor-phase catalytic oxidation of at least one compound selected from the group consisting of propylene, isobutylene, t-butanol and methyl-t-butyl ether and a method for the production of unsaturated aldehyde and unsaturated carboxylic acid by the use of this catalyst are provided. The catalyst of this invention comprises (A) a catalyst having Mo, Bi and Fe as essential components and used for the production of unsaturated aldehyde and unsaturated carboxylic acid by vapor-phase catalytic oxidation of propylene, isobutylene, t-butanol and/or methyl-t-butyl ether and (B) a solid acid having acid strength (Ho) of not more than -11.93. Since this catalyst excels in catalytic activity and service life, it allows unsaturated aldehyde and unsaturated carboxylic acid to be produced stably at a high yield for a long time.

Abstract: A pile forming warp knitting machine having a spaced plurality of needles and a pair of separate sinker assemblies. These sinker assemblies have a plurality of pile sinkers and a plurality of enclosing, knock-over sinkers. Both pluralities of sinkers are interdigitated with the needles. The pile sinkers each have a distal edge and a proximal edge. The knock-over sinkers each have an enclosing recess. The knock-over sinkers also have (a) an exposed first segment with a knock-over edge, (b) a second segment integral with the first segment, and (c) an enclosing nose integral with the second segment and having an inside edge extending alongside the second segment at a predetermined distance therefrom. In a first working mode the knock-over sinkers reciprocate relative to the needles between an enclosing position and a knock-over position. The enclosing position is at the enclosing recess. The knock-over position is external to the enclosing recess.

Abstract: Textile machine in particular a warp knitting machine having attached, side-by-side, on a carrier (1), stroke elements (2) which grip on the threads, which are individually displayable in the longitudinal direction. To the carrier (1), are provided control element (21) which are electrically activatable and can be brought into two positions. A common activating arrangement (8) which runs along the length of the carrier (1) and is driveable to and fro in the stroke direction, influences the stroke element (2) in the first position of the appropriate control element (21) in the at-rest position and carries it with it in its second position in a working mode. In this manner it is possible to control the individual stroke elements without the need for harness cords.

Abstract: Treatment or prophylaxis of depressed or inadequate intracellular pyridoxal phosphate levels in a human or animal patient resulting from a condition, wherein the pyridoxine (PN)--pyridoxal phosphate (PLP) pathway is disturbed by cellular defects and concomitant enzyme deficiencies. These may be due to genetic causes or cell immaturity, as occurs in infants and in diseases resulting in erythrocytes destruction. In infants it was found, for the first time, that this leads to elevated homocysteine levels.The deficiencies are counteracted by the administration of pyridoxal or a precursor of pyridoxal which in vivo, once it has entered the bloodstream, is rapidly convened into pyridoxal without the intervention of oxidase or oxygen, optionally and preferably without the intervention of kinase and/or of PN in slow-release form and at a daily dosage rate not exceeding 0.7 mg/kg/day in the long term.

Abstract: In a method for manufacturing a warp knitted fabric, the guides can also be displaced by one needle space (pitch) in addition to the overlap and underlap shog of the guide bar, so that the guides are not only selectively displaceable during the underlap shog, but also selectively during the overlap shog. A warp knitting machine for the purpose of carrying out the method comprises at least one thread system which consists of pattern threads laid in intermixed, varying patterns. These pattern threads have underlaps of n, n+1 and n-1 needle spaces and can produce a float and/or a twill. The number of pattern possibilities can be increased in this manner.

Abstract: A pair of pleats are formed from the same panel on one side of a cylindrical polyethylene bag in which a film of heat sensitive adhesive layer is on the bag layer to form the necessary heat seals. The bag has a lengthwise seam that is formed as an edge of one of the pleats. The other pleat is folded over material from the one panel. The bag is opened by pulling one of the pleats and an edge of the bag with the other pleat between the two pulling points. The pulling forces separate the layers of the one pleat permitting easy access to the bag which is sealed at both ends. The pleats are preferably sealed along the bag length end to end and share a common junction with the one panel from which they are formed.

Abstract: In a process for the production of short warps, especially pattern weaves, an individual thread (1) of different or the same color is wound up on a wind surface (9,11) sequentially with turns lying next to each other in an individual layer. This layer corresponds to the warp length. A thread guide (4) is movable around the circumferential contour of a wind-up arrangement (2) in the wind plane. A forwarding arrangement further moves the side-by-side wound thread warp at each circuit of the thread guide (4) by an amount equivalent to the thread thickness. The first individual threads (1) are wound on a support surface (11) displaceable orthogonal to the wind plane (10). Each further individual thread (1) is wound onto the previously wound thread warp (18), having been displaced rearwardly by an amount at least equivalent to one thread thickness.
