Title: Process for the manufacture of vinyl pyridines and vinyl quinolines and their homologues
Inventor: RUNGE FRANZ
IPC: C07D215/04
Filed: 1956-03-14
Abstract: Vinyl pyridines, vinyl quinolines, and their homologues are prepared by dehydrogenating the corresponding ethyl compounds at raised temperature in the vapour phase and in the presence of a diluent vapour or gas, e.g. H2O, CO2 or N2, and a dehydrogenating metal oxide catalyst formed into spherical or cylindrical shapes.  Suitable catalysts are zinc oxide plus a non-volatile salt, oxide or hydroxide of an alkali or alkaline earth metal; and a dehydrogenating trivalent metal oxide especially aluminium or chromium oxide or both, alone or with zinc oxide, and said alkali or alkaline earth compounds.  In examples: (1) 4-ethyl-pyridine plus water vapour is passed at 600-650 DEG  C. over zinc oxide+aluminium oxide+ calcium oxide, and the product fractionated to recover 4-vinyl-pyridine; (2) 2-methyl-3-ethylpyridine is similarly dehydrogenated over aluminium and chromium oxides.

Abstract: 978,505. Safety harness. LICENSSYSTEM A.B. March 7, 1961, No. 8202/61. Heading A3V. [Also in Division E2] In safety harness for use in motor vehicles, chest and lap straps 13, 14 anchored to the vehicle are connected to each other and to a lap strap 18 by a buckle comprising members 5 and 9 which in the locking position are pivotable relative to each other in a plane. The ring 9 during locking momentarily deflects a U-shaped member 4, pivotally mounted on a shaft 3 against the action of an adjustable spring 2, to engage the lug 5 pressed up from a base plate 8. To release the ring 9 a lever 1 against which the member 4 abuts is raised which pivots the member 4 to the left as shown in Fig. 3. The strap 18, of which the upper run is anchored to the vehicle, is passed around a shaft 7 carrying an eccentric 22 and mounted in slots 21 in upturned walls 11 of the member 8. Pull on the upper run turns the eccentric 22 to clamp the strap against a part 8a of the member 8. To allow lengthening of the strap, the shaft 7 is moved to the wider end of the slots 21. Fig. 6 shows alternative adjusting means comprising rollers 23, 25, the strap being freely movable in both directions when the roller 23 which is preferably knurled is moved away from the smooth roller 25. The strap 13 is preferably anchored to the vehicle at shoulder level on the centre pillar or beneath the rear window and the strap 14 on the centre pillar adjacent the floor or on the floor itself. The strap 18 is preferably mounted on the gearbox tunnel. In a four door vehicle, the straps 14 and 18 may have a common anchorage on the floor behind the user's seat.

Abstract: 541,780. Dividing and moulding dough. HARBER, L. S., POINTON, J. E., and BAKER PERKINS. Ltd. May 7, 1940, No. 8205. [Class 87 (ii)] A conveyer delivering dough pieces from a divider has associated with it a device, which can be put into or out of use, for collecting a number of the pieces, so that they are passed on as a single larger piece. Speed control means is provided so that, when the collector is not in use, the dough pieces on the conveyer are evenly spaced, but, when it is in use, they are in spaced batches. The apparatus can thus be arranged to deliver dough pieces suitable for rolls or for a composite loaf, as described in Specification 400,619, [Group VI], or, alternatively, to deliver pieces suitable for a normal loaf. Fig. 1 shows a multi-pocketed divider 10 delivering on to a conveyer 12 which passes the pieces to a helical belting channel 16 on a rotating conical table 15. The divider delivers small pieces and when a plate 17, Fig. 2, with a depending hump 19 and which is pivotally supported on a pivoted arm 18, is brought into position adjacent the conveyer 12, it collects and roughly balls together a number of small pieces and they are passed on to the moulder as a single piece. The moulded pieces are delivered from the upper end of the channel 11 on to a conveyer 36 by aid of a fluted roller 37 on a shaft 38, Fig. 5, carried by an arm 39, pivotally mounted on the fixed shaft 40 of the moulder and adjusted thereon, according to the size of the dough pieces, by means of worm gearing 46, 45. The spindle 38 is driven by a gear train 44, 43, 42, the wheel 42 being fixed to the core 15. Specification 480,869 is referred to.

Abstract: 1,206,719. Extruding and severing dough. H. REISMAN. 21 Feb., 1968, No. 8526/68. Heading B5A. Shaped dough articles, e.g. pretzels are produced by extruding a stream of dough through an orifice of a desired shape across which is moved a knife in contact with the surface of the extruder having the orifice therein and at an angle of 10-30 degrees to the surface to sever dough cleanly from the stream without obstructing flow. The angle is preferably 15-25 degrees. As shown in Fig. 2, the apparatus comprises an extruder 20 having an exit plate 26 in which are disposed orifices (28, Fig. 3, not shown) and above which are a plurality of spacer bars 88 to separate material. Plate 26 comprises an outer plate 96 having forming channels 98 (Figs. 14, 15) and an inner plate 94 having feeding channels 100, connected with forming channels 98 by holes to trap lumps of material. Cutter assembly 10 comprises lever 65 carrying a knife 64 having an edge 38 and pivoted at 54 to frame 52, there being a spring 57 co-operating between arm 58 of frame 52 and lever 65 to urge knife edge 38 into contact with the exit surface. Frame 52 is slidably mounted in sleeve 62 on main extruder assembly 24 and reciprocated by arm 46 connected at one end to frame 52 and at the other to arm 50, rigidly fixed to and rotated by a wheel driven by belt 48. Knife 64 is guided by pin 80 and has lugs 78, Fig. 1, acting as cam followers to follow the cam surfaces 70, 116, 72, 118 of block 69 to sweep across exit surface of plate 96 and be retracted downwardly and then rearwardly therefrom by such cam means after severing the dough pieces 16 which fall on to conveyer 34 located sufficiently close to the extruder orifices to avoid distortion.

A cold-parison process comprises producing a tubular parison by a normal extrusion process at a temperature, for example, in excess of 170‹ C., and then either cooling the parison for storage and subsequently re-heating it within the range of 100-170‹ C. or, partially cooling the parison, after extrusion, to within the latter range, and then blow-moulding the parison at this temperature to produce the moulded container. The preferred temperature range is 125-160‹ C. and, more precisely, 140-150‹ C. The cold-parison process is stated to improve burst strength, drop height, colour, and clarity and allows containers to be of lower weight and rubber content. The homogeneous copolymer may contain additives such as heat-stabilizers. A graft copolymer is prepared by a method similar to that described in Example 4 of Specification 1,185,306 and is latex blended with an acrylonitrile-styrene resin made by the method described in Specification 1,185,305, but containing 87À5% molar acrylonitrile to give a blend containing 12% by weight of rubber. A tubular parison was moulded from a sample of the blend using a melt temperature of 180-190‹ C. and a die temperature of 195‹ C. the parison then being cooled to 145‹ C. and blown in a mould to form a bottle.

Abstract: 1,133,740. Detonating fuzes. TELEDYNE Inc. 28 Feb., 1966, No. 8620/66. Heading F3A.  A detonating fuze cord assembly including an end probe, is adapted to be releasably coupled to other parts of an explosive train, and is designed to avoid the explosive escape of particles during the detonation. The end of a fuze cord 10 is reduced to provide an extending part 32 of smaller diameter than the cord 10. For a large fuze this may require the quantity of explosive distributed linearly to be reduced, but in small fuzes the reduction may be only of the parts covering the explosive. The reduced part 32 extends through and beyond a coupler body 12 and is surrounded by a sealing cap 20 of stainless steel or aluminium, which may enclose a booster charge 22, so as to form a probe. The coupler body 12 is provided with a bayonet-type connector 14 for connection to an adjacent part 24 having an explosive train chamber 26 into which the probe enters. In modifications, Figs. 2-5 (not shown), two probes are connected to a body (36), Fig. 2, to actuate a common percussion member (44) which ignites a main charge (50), or four probes are connected to a common body (Fig. 3).
