Title: Improvements in looms having a continuous weft feed and in weft inserters or shuttles therefor
IPC: D03D47/24
Filed: 1924-10-28
Abstract: 230,784. Mullor, A., and Carriol, L. March 14, 1924, [Convention date]. Weft-inserters not carrying cops, bobbins, and the like, looms with.-Weft is inserted in loop form from bobbins at each side of the loom by means of a weft inserter or " shuttle " s having a longitudinal groove receiving a rod 1 formed with hooks 5 at each end fitting in cavities 8 in parts 9 thus forming pincers. The hooks are furnished with guiding-tongues 10. After the " shuttle " has been moved to the left, the righthand pincers having inserted a loop of weft in the shed, a hook 11 pivoted to a support 16 on a sliding rod 13 controlled by lever mechanism and a cam presses the " shuttle " to the left until its right-hand end is level with the selvedge. Subsequently a roller 20 on the hook engages a cam and the end of the hook is thereby caused to engage through an aperture in the " shuttle " with the rod 1 thus causing the pincers to open and liberate the weft, as shown in Fig. 3. The loop of weft is retained at theselvedge by the shed changing. The weft from the left-hand bobbin is now engaged by the opened left-hand pincers, which then close, and the " shuttle " is moved to the right to insart this weft in loop form. The wefts from the bobbins extend to eyelets 24, on levers 25 which are specially operated, and through grooves in the front plates of the shuttle-boxes. Means for supplying weft of different colours to the " shuttle " are described. A modification shown in Fig. 7 is also described wherein the weft necessary to form a loop is first unrolled before insertion, a modified " shuttle " for inserting this weft being used.

Title: Method for the production of a self-supporting electrical winding
IPC: H01F41/06
Filed: 1976-06-23
Abstract: 1497648 Making electrical windings SIEMENS AG 23 June 1976 [15 Sept 1975] 26072/76 Heading B3A [Also in Division H2] - In a method of making a self-supporting electrical winding, the turns of a first layer 18 of the winding, Fig. 2, are wound with a first uniform pitch and packed tightly together, the turns of the next layer 20 are then wound about the first layer with a second uniform pitch and separated from one another by a substantially constant distance, and finally a liquid potting agent 24, e.g. an epoxy resin, is applied to the external periphery of the winding so that it penetrates between the turns of the layer 20, reaches the layer 18 and flows about the turns of the latter, so that potting of both layers in the agent is achieved. The winding may be used as a coil in a moving-coil motor. As shown, a coil body 10, Fig. 3, is pushed on to one end of a segmented mandrel 26 and a guide ring 28 is disposed on its other end. The mandrel is then expanded by means of a coned disc 30. The winding, which has two parallel wires, is brought out through a groove 14, Fig. 1, in the coil body 10 and through a lead-in (not shown) in a collar 16, Fig. 2 of the coil body. Winding of the inner layer on the mandrel, which is rotated, is begun with the first turn abutting against the collar 16. The guide ring 28 is pushed against the last turn of the inner layer so as to press the turns of the layer together. Woven glass-fibre 22 is then placed on the inner layer and cemented to the coil body. The winding is then taken through a gap 34 and a lead -in in a collar 32 on the guide ring, Fig. 5, and the outer layer 20 is wound with an opposite hand over the inner layer and the collar 16. The spacing of the turns of the outer layer is adjusted by means of a spacing roller, Fig. 8 (not shown), which is provided with channels and which is pressed against the outer layer while it is wound so that the winding wire entering the outer layer runs through a first of the channels and, for guidance of the roller, turns already wound run in the other channels. After the outer layer has been wound rotation of the mandrel is discontinued and with the winding thereon it is preheated and dried. The liquid potting agent is then dripped on to and along its outer periphery of the winding so that it penetrates into the winding. Hardening of the winding is then effected in an oven after which it is cooled and the mandrel is withdrawn.

Abstract: <PICT:0482349/IV/1> Apparatus for intermittently treating a running yarn, as in the production of variable denier artificial filaments by stretching, as described in Specification 321,762, [Class 2 (ii)], and in the intermittent saponification of cellulose acetate or other cellulose ester yarn, comprises a yarn-engaging member moved in a direction transverse to the path of the yarn by an epicyclic gear in association with speed-controlling means whereby the frequency of movement of the yarn-engaging member is varied.  As applied to dry spinning of artificial silk, a yarn-deflecting bar 17, adapted to engage filaments issuing from a cell 6, is operated by a crank 19 driven from an epicyclic gear box 25 which is driven by sprockets 23 from the godet shaft 10.  The epicyclic gear comprises planetary wheels oscillated by adjustable crank gear 48. Further variation may be effected by slightly varying the speed of the godet shaft, or elliptical wheels may be introduced in the train between the gear box and the crank 19.  Specification 412,600 also is referred to.

Abstract: The invention comprises unsaturated ketones having the general formula <FORM:0785086/IV (a)/1> wherein R1 represents a C2-5 alkyl radical or a phenyl radical and R2 represents methyl or R1 and R2 together represent the pentamethylene radical.  They are obtainable by reacting a vinyl alcohol <FORM:0785086/IV (a)/2> wherein R1 and R2 are as defined above, with a hydrogen halide or phosphorus halide, condensing the resulting substituted primary allyl halide with an alkali metal salt of an acetoacetic ester and submitting the resulting substituted aceto-acetic ester to a ketonic hydrolysis. The vinyl alcohols are preferably reacted with concentrated aqueous hydrogen chloride or bromide or with phosphorus tribromide.  The condensation step may be effected with the alkali metal salt of the aceto-acetic ester in an inert solvent or with the ester itself and an alkali metal alcoholate.  In examples: (1) 3-methyl - penten - (1) - ol - (3) is reacted with aqueous HCl, the resulting 1-chloro-3-methylpentene-2 is isolated and reacted with a mixture of ethyl aceto-acetate and sodium methylate yielding 3 - carbethoxy - 6 - methyl - octen - (5) - one-2 which is treated with KOH in aqueous ethanol to form the potassium salt of the corresponding ketonic acid and then with concentrated hydrochloric acid giving 6-methyl-octen-(5)-one-2; the ethyl aceto-acetate may be replaced by the methyl ester; (2) 1-vinyl-cyclohexanol-(1) is reacted as in (1) to give 5-cyclohexylidene-pentanone-2 and (3) in the same manner, 3:5 - dimethyl - hexen - 1 - ol - (3) is used to form 6:8-dimethyl-noren-(5)-one-(2).  Another specified alcohol is 3-phenyl-buten-(1)-ol-(3).  The unsaturated ketones have the properties of perfumes.  Specification 735,828 is referred to.
