Title: Improvements in circular knitting machines with wrap thread mechanism
IPC: D04B9/10
Filed: 1944-10-09
Abstract: 589,053. Knitting-machines. WILDT & CO., Ltd., and HOLMES, H. H. Oct. 9, 1944, No. 19323. [Class 74 (ii)] In a knitting machine provided with wrapthread mechanism, movable guiding means are arranged to function eccentrically with respect to the wrap-thread head so as to act upon the wrap-threads at a point removed from the knocking-over point so as to draw and measure off the threads from the bobbins, but to permit the threads to run slack at the knitting point. The invention is described in connection with a double-cylinder machine. The thread-guides may perform either single needle or multineedle wrapping. The threads in passing from the bobbins to the thread-guides pass through eyes 29 in a disc 19 mounted eccentrically of the needle cylinders and rotating therewith. The disc 19 is mounted upon a base plate, which to provide for adjustment of the eccentricity is pivotally mounted by a fulcrum screw 26 on a plate 21 rotating concentrically with the needle cylinders, and is secured in the adjusted position by a locking screw 27 carried by the base plate and passing through a slot 28 in an extension of the plate 21. A post 10 of the bobbin socket engages a slot 24 in the disc 19 to drive the disc. Specification 455,801 is referred to.

Abstract: 1,102,612. Reciprocating dispensing pumps. LES VAPORISATEURS MARCEL FRANCK. May 7, 1965 [May 12, 1964], No. 19366/65. Heading F1A. An atomizer pump mounted on a container has an air inlet into the container which is closed by the piston at the end of its suction stroke to which position it is urged by a spring. In Fig. 1 the piston 3 is shown closing the air inlet 8. The outlet valve comprises a skirt 3 1  overlying a passage leading to the nozzle 11; frictional engagement of the piston 3 with the cylinder causes the skirt 3 1  to flare outwardly on the delivery stroke. In a modification Figs. 3, 4 (not shown) the piston comprises a ring slidable between two shoulders and controlling the outlet passage. In addition a sleeve valve is provided which permits the entry of air into the container only when subatmospheric pressure is created therein. The inlet valve comprises a member 17 which is moved relative to the seat 13 1  by engagement with the rod 12 extending from the piston.

Abstract: 614,255. Lenses and other optical elements. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. June 28, 1946, No. 19382. Convention date, Oct. 10, 1939. [Class 97 (i)] [Also in Group V] Lenses or other optical elements are made from material gelatinised from a solution and dried; the element may be hardened. The element may be a correcting element 9, Fig. 3, for use in correcting spherical aberration in a reflecting objective, and may be formed from a colloidal solution of gelatin, agar-agar, pectin, &c., or of silicates or aluminium oxide with or without glycerine. The solution may be passed through a tube 6 on to a plate 2 beneath a hollow mould 3 maintained by water circulating through pipes 4, 5, at a temperature such that the material remains in solution. Gradual reduction of temperature gelatinises the solution and produces a mass 7. The mass is dried and its heights become reduced as shown in Fig. 3, while its dimensions parallel to the plate remain the same. The enlargements existing in the mould of the desired heights in the element enable greater accuracy to be obtained in the finished element. Hardening may be effected by formalin &c.

Abstract: 731,409. Slicers. KOOPERATIVA FORBUNDET. July 13, 1953, No. 19416/53. Class 5 (1). [Also in Groups VI and XIV] Chord-like strips 11 can be cut off a vegetable root 10 by a U-shaped right-angled knife 6 protruding from the middle of a bar 1 attached to a reciprocated handle 3, the actual cutting being done by the sharp ends of the angle. The knife 6 is prevented from cutting into the trencher board or support 9 by a downwardlyprojecting bent end 8 of the knife. The side of the knife is in the same plane as the side 7 of the bar 1 so that it acts as a guide bearing against the cut side of the root 10. Fig. 8 shows a knife blank 6 before being bent and removably attached to the bar 1 by a screwed bolt. In Fig. 11, the root 10 is reciprocated by hand over a plate 15 to a stationary knife 6, the slices 11 falling into a box 18. The auxiliary plate 15 spaced from the plane of the plate 1 determines the slice thickness.

The structural materials specified are glass fibre reinforced resins, e.g. laminates, wherein the resin may be of the polyester, epoxy or phenolic type; glass fabric impregnated with catalysed polyester resin (Example (2)); and fibrous materials such as wood and agglomerated wood chips, wood fibres, sawdust or asbestos fibre cement, the latter optionally being moistened with catalysed polyester.  The formers used are moulding dies or carriers, e.g. flat plates, and may be of metal or glass.  Polyesters disclosed are derived from maleic and fumaric acids or anhydrides and may be modified with materials such as stearic, adipic phthalic or sebacic acid, allyl or decyl alcohol, or linseed oil fatty acids. The aromatic monomer may be styrene or divinyl benzene.  Benzoyl or methyl ethyl ketone peroxide may be used as catalyst, optionally in conjunction with accelerators such as cobalt naphthenate and diethylaniline and inhibitors such as a -naphthol and hydroquinone. If desired the glass fibres may be in the form of a mat, fabric or roving.  Other optional ingredients are pigments, dyes and fillers such as wood meal, asbestos fibre, clay, mica, talc, calcium carbonate, kaolin, zinc oxide and titanium dioxide.  Flat panels for decorative purposes may be obtained and, if required, additional coatings of nitrocellulose or baking varnishes may also be applied.

Title: Manufacture of aliphatic dienes
IPC: C07C1/20
Filed: 1943-12-01
Abstract: Aliphatic dienes are produced by reacting di-b -alkenyl ethers with alkali metal.  A b -unsaturated alcohol and b -unsaturated alkyl halide may be reacted in the presence of caustic alkali or alkali carbonate, and the ether produced reacted with alkali metal.  Diallyl ether gives 1.5-hexadiene, dicrotyl ether, 2.6-octadiene, and dimethallyl ether, 2.5-dimethyl-1.5-hexadiene. Diallyl ether reacts at room temperature with sodium, and the reaction is preferably effected at not more than 100 DEG  C.  An inert diluent such as xylene, toluene, a less reactive ether, an excess of the starting material or the reaction product may be used.  The metal alcoholate such as sodium allylate obtained as a by-product can be converted back to the ether with the appropriate alkyl halide.  In an example, allyl alcohol is refluxed with caustic soda and allyl chloride added, the crude diallyl ether being distilled off and purified by fractionation.  Sodium is added thereto and the mixture finally heated to distil the hexadiene. The ether and sodium, suspended for example in a diluent such as n-hexane, may be fed continuously, and hexadiene, with hexane if used, distilled off as formed.
