Title: Improvements in knitting machines
IPC: D04B35/02
Filed: 1919-09-09
Abstract: 141,660. Wilcomb, J. F. April 12, 1919, [Convention date]. Circular machines; parallel machines; needles. -Relates to an improved knitting or crotchet unit which avoids objectionable features present in the latch and in the spring-beard type, and to an improved machine organization co-operating therewith. The needle unit comprises a yarndrawing member 1, Fig. 1<a>, having a hook 3, throat 4, shank 6, and butt 5, slidably mounted in a loop-spreading quill 2 of channel form with thin parallel side walls, and having a nose 7, rise 8, swell 9, drop 10, throat 11, stem 12, base portion 13, butt 14, and a riveted block 15 which may act as a stop for the needle. The nose 7 may work in a V-groove 29 at the back of the needle stem to ensure the quill 2 entering the loop, or the back of the needle may be flattened only. Fig. 1<a> shows the loop-building operation just completed; in forming the new loop, the needle first advances relatively to the quill to open the hook for receiving the new yarn. Fig. 3 shows the needle further advanced and followed up by the quill which has passed into the old loop and lodged it in the throat 11. Fig. 4 shows the needle again retracted into the quill and a further downward movement of needle and quill knocks the old loop over and brings the parts again into the position shown in Fig. 1<a>. In a modified form the needle has a hump 17, Fig. 8, somewhat larger than the corresponding swell of the quill; this reduces the abrasive action of the quill walls on the loop. To avoid expanding the loop too much, the needle and quill are recessed at 19, 18. In another modification, the quill has inwardly curved points 20, Fig. 10, to ensure penetration of the loop. Another form of needle for use in machines where each needle draws its own loop of yarn, has a large bent hook allowing free access to knots or bunches. Where yarn is fed by sinkers a much flatter type of hook, suitable also for plating, is used. The needle butts 5 and quill butts 14 may be controlled by separate cam tracks, or the needles may be in part controlled by contact of the butts with the quill stop 15 or by projection of their stems through the quills within range of friction jacks 26, Fig. 16, mounted below the quills to act as guards to restrain the needles from overshooting the lower point of the stitch cam. This construction automatically neutralizes or compensates for wear and upsetting effect on jacks and needles, and the wear due to impact of needles is spread over a large number of jacks instead of being concentrated on one part of a guard cam. The improvements may be applied to the Lamb type of machine. The needle and quill unit 1, 2 may be operated by hand.

Title: A process for producing partially chlorinated amine boranes
Inventor: BORER KEITH
IPC: C07F5/00
Filed: 1959-06-29
Abstract: The invention comprises the compound BHCl2.N(CH3)3, and a method for producing partially chlorinated tertiary amine boranes of the formula R.BHmX3-m where R is a tertiary amine, X is a chlorine atom, and m is 1 or 2, by reacting in the absence of water a tertiary amine with an etherate of a partially chlorinated borane. The tertiary amines used may contain aliphatic, cycloaliphatic, aromatic or heterocyclic groups or may be heterocyclic bases in which the nitrogen atom is a member of a ringsystem.  These groups may carry alkoxy, fluorine or aromatic chlorine substituents.  Polyfunctional tertiary amines may be used. Tertiary alkylamines are preferred.  The reaction is preferably effected in a liquid medium in which the medium may be a hydrocarbon, halogenated hydrocarbon, or ether, especially diethyl ether or tetrahydrofuran.  Alternatively the amine reactant may be used in excess as the medium.  In an example trimethylamine-dichloroborane is made by reacting trimethylamine with dichloroborane diethyl etherate obtained from boron trichloride and sodium borohydride.  Specifications 881,376 and 899,558 are referred to.

Title: Improvements in flotation of fine refuse coal
IPC: D01D10/04
Filed: 1937-08-17
Abstract: Fine refuse coal, e.g. anthracite culm, is cleaned by first subjecting it to froth flotation with flotation reagents in amount insufficient to float the fine particles having a high ash content so that the concentrate obtained contains a major portion of the fine low ash coal, and then classifying the tailings from the flotation operation, e.g. by screening, rejecting the fine sizes, and floating the coarse sizes with an amount of reagent sufficient to float the coarse low ash coal.  The first flotation is preferably carried out with a frother consisting of a mixture of paraffin alcohols having from 7-10 carbon atoms stabilized with a hydrocarbon, as described in Specification 446,418, and for the second flotation a hydrocarbon collector, e.g. kerosene, is added.  One or both of the concentrates may be cleaned by re-floating and the concentrates may be kept separate or mixed. In an example, after flotation of the finest coal with the alcohol-hydrocarbon frother, the tailings are classified in the presence of sodium silicate, and the coarser coal floated with kerosene.

Title: Improvements in and relating to devices for determining the phase of an alternating voltage
IPC: G01R25/00
Filed: 1932-08-15
Abstract: 382,933. Synchronism indicators. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A. -(Assignees of Allgemeine Elektricitõts Ges. ; 2, Friedrich Karl-Ufer, Berlin.) Aug. 15, 1932, No. 22839. Convention date, Aug. 14, 1931. [Class 37.] For determining the phase position of an alternating voltage or the phase relationship between two alternating voltages, a rotatable luminous device is energized from the voltages under examination so as to become intermittently luminous at regularly recurring stages in the alternations of these voltages. In the construction shown, two alternating-current networks a, b are arranged to be coupled together by an oil switch c. On a disc d, rotatable by a motor g, are mounted two luminous tubes el, e<2> connected to condenser coatings f<1>, f<2> on the bushings of the switch c. If the motor g runs synchronously with one of the networks, the tube connected to this network produces a steady luminous strip or zone as it lights up for a short time during each half-wave. If the voltages of the networks a, b are not synchronous, the strip produced by the other tube appears to move away from that produced by the first tube, the strips coinciding when the two voltages correspond in phase. As the tubes light up during each half-wave, oppositely connected valves h<1>, h<2> are included in series with the tubes to suppress the current through the tube during one half-wave, in order to distinguish between phase-coincidence and phase-opposition. Alternatively the electrodes of the tubes may be so constructed that illumination occurs during only one half-wave. The tubes may be of different colours, such as red and green, and may be placed at different distances from the axis of the disc. Tubes of any shape may be employed and covered by a screen with a strip-shaped opening. The tubes may be connected to wires stretched parallel with the high-voltage lines, instead of to the condenser coatings h<1>, h<2>. In order to obtain as small a luminous strip as possible, the curve of voltage supplied to the tubes should be of sharp curvature at successive maxima. Tubes with hot cathodes may be employed and supplied by the discharge of condensers. One tube only may be employed with a rotating change-over switch. A switch may be provided so that the supply from each network may be interrupted individually.

Classes 83 (i) and 83 (ii). [Also in Groups V and XXXVI] Rectifiers of alternating electric current of the kind comprising pieces of germanium, silicon or other semiconducting material mounted in metal holders are made by casting a body of the material in the form of a number of projections 12, Fig. 6, each of a size and shape to fit a holder, connected by a thin web 13. The holders are then fitted and the web cut or broken to separate the articles. A mould for two such castings comprises a tube 1 having a tapered bore 2 in which fits a plug 3 having the necessary flats 5 to produce the.web 13, recesses 7 to produce the projections 12, a recess 8 for a charge of the material and gates I0. Solid material is placed in the recess 8, the mould is arranged in a chamber which is evacuated, the mould.is heated, e.g. by H.F. induction, to melt the charge and air or gas is admitted to force the charge into the mould. Precautions may be taken to prevent undesired, or ensure desired, changes in casting, e.g. by using an inert gas and a mould of carbon or silica. After cooling, which may be controlled, the casting is removed by tapping the projection 11 and withdrawing the plug 3. The casting may be supported by a perforated sheet &c. while the sides of the projections are coated with metal. The holders are then soldered on and the articles separated.
