Title: Improvements in the Die-heads of Screw-cutting Machines.
Inventor: HARRIS CLAUDE WILLIAM
IPC: B23G5/04
Filed: 1917-02-09
Abstract: 113,003. Harris, C. W. Feb. 9, 1917. Screwing-dies.-In a die head, which is applicable for cutting either right-hand or left-hand threads, the chasers f are received in slots in holders e<1>, e<2>, e<3>, e<4>, situated in V recesses in the head a, and capable of being swung on pivots c<6> to one side or the other of the recesses for right or left hand screw threads respectively. The holders e<1> &c. are adjusted according to the size of the work by plates k sliding in grooves in the head and acted on by cam surfaces on a ring l. For left-hand work, the plates are transferred to grooves j<1>. The ring l is in two parts secured together by studs. The outer part is secured by T headed bolts m to a plate n which can be moved axially on the spindle c by a knock-off lever. The axial movement of the ring l disengages the plates k, the cam surfaces of the ring l being conical as shown. The chasers f are adjustable by screw bushes h, are formed with flanges engaging grooves in the holders and are secured bv studs. In a modification, the holders are positively operated, being pivoted to the plates k, which are formed with slots engaging cam flanges on the ring l. The knock-off mechanism trips a detent between the die head and the plate n, thus permitting springs interposed between the die head and the plate n to revolve the latter and release the plates k.

Title: Process for the preparation of fluorocarbons
IPC: C07C17/10
Filed: 1944-02-03
Abstract: Fluorocarbons are produced by the action of cobalt trifluoride or manganese trifluoride at between 150-400 DEG  C. temperature on a hydrocarbon in the vapour phase.  The cobalt trifluoride may be produced in situ by fluorinating cobalt difluoride.  According to the plan of apparatus provided, a cylinder containing cobalt trifluoride is heated to 150-400 DEG  C., and the hydrocarbon, e.g. C7H16 is passed in.  The products of the reaction C7F16 and HF are separated as liquid phases.  The fluorination of the CoF2 to the higher fluoride is provided for.  Other hydrocarbons specified include C8H18, which gives C8F18, and dodecahydrodiphenyl which gives C12F22. All types of hydrocarbon are included in the reaction, including olefinic and aromatic.ALSO:Cobalt trifluoride may be prepared by dehydrating cobalt chloride hexahydrate CoCl2.6H2O to the anhydrous form, treating it with anhydrous hydrogen fluoride to give cobalt difluoride, and converting this into the trifluoride by direct fluorination at any suitable temperature above 150 DEG  C.

Title: Improvements in the manufacture and use of textile threads
IPC: D06B7/08
Filed: 1934-01-20
Abstract: 437,019. Twisting artificial threads. BRITISH CELANESE, Ltd., 22, Hanover Square, London.- (Celanese Corporation of America; 180, Madison Avenue, New York, U.S.A.) Jan. 20, 1934, Nos. 2070 and 16242. [Classes 120 (ii) and 120 (iii)] Highly twisted crÛpe threads of cellulose acetate filaments are obtained by crÛpe twisting the threads in a single stage and during insertion of the twist steaming the threads under conditions such that moisture is present. During the twist the threads may be passed through a closed chamber maintained full of steam under conditions such that moisture is present. The threads produced are smooth, and cylindrical and extremely closely packed so that the apparent specific gravity of the thread may be more than 85 per cent of the actual specific gravity of the filaments. A minimum twist of 70 turns per inch for a crÛpe thread of 165 deniers, and 85 turns for a crepe thread of 115 deniers may be given. The threads are stretched during the twisting treatment. The threads may be of continuous or discontinuous filaments. The filaments may contain water-insoluble compounds such as pigments and loading material. Sizes such as casein, egg-albumin, and linseed oil, may be applied to the threads at any stage of the manufacture. The thread may be drawn off over the end of a rotating package through a guide in line with the axis of rotation and passed on its way to a bobbin through steam under conditions such that moisture is present. A ring-twisting device may be used. Flyers, floating-rings, or other devices may be used to restrict the amount of ballooning of the thread or the tendency of the twist to run back to the package. Steam may be passed through a chamber situated vertically over one or more twisting spindles, and provided with inlet and outlet holes for the threads. The presence of moisture is assured by supplying wet steam or arranging for condensation, or wetting the thread with water The steam may be at atmospheric or elevated pressure. The resulting crÛpe threads may be associated with low or highly twisted threads of cellulose acetate, regenerated cellulose, natural silk or other material in the production of fabrics which are subsequently scoured. Salts or sugars may be incorporated in the scouring baths to minimize the delustring effect. Specifications 304,806, [Class 120 (ii)], 348,589, 424,683, 424,752, 424,830, and 424,879 are referred to.

Abstract: 524,099. Reciprocating conveyers. PRESCOTT, W. E., BAKER PERKINS, Ltd., and ANCIENS ETABLISSEMBNTS A. SAVY, JEANJEAN ET CIE. Jan 21, 1939, No. 2187 [Class 78 (i)] [Also in Group XIII] Reciprocating conveyer apparatus, for carrying trays of material through ovens or through cooling and drying-apparatus, comprises two sets of alternately-acting supports, one set of which raises a column of trays one step and then transfers them to the other set which moves inwardly to engage them. The first set then moves outwardly and downwardly before commencing a fresh upward movement in which it again moves inwards and supports the trays ; the second set then moving outwards to allow a second upward movement of the trays to take place. In the preferred arrangement step-by-step ascending and descending columns of trays are worked in unison and provision is made for transfer from one column to the.other at the top of the 'apparatus and for combined feeding to and delivery from the system at the lower end. In the illustrated form four rods 7 raise trays step-by-step and four rods 13 lower them. A cam shaft 23 raises and lowers these two sets of rods in unison through the medium of the bellcranks, 20, 21 and the tables 18. Other cams 34, 35 on the shaft work in synchronism with the lifting-apparatus to move the rods horizontally by operating the bell-cranks 38, 39 against the action of the springs 36' and so rolling the wheels 121 on the rods 7 on the tables 19 until the pins 15 on the rods engage and disengage the trays. In addition these cams move the supporting rods 10, 14 on the tracks 12 in synchronism with the movement of the conveyer rods. Another cam operates the linkage 62, 61, 57, 56. This reciprocates a tray-holding frame furnished with pawls 52 at each end. On the forward stroke, the rear pawl pushes one tray 5a into the ascending side of the system while the forward pawl delivers one from the descending side. On the return stroke the pawls are tripped by, and pass under the trays. In addition, the linkage, by means of the additional links 58, 60, 59, 63 operates' a second sliding tray-holder' which transfers the uppermost tray from the ascending to the descending side.
