Title: Improvements in and relating to steelyards
IPC: G01G23/00
Filed: 1925-02-03
Abstract: 235,109. Williamson, G. E., Hart, E. A., and Hart & Co., Ltd., D. Feb. 3, 1925. Steelyard apparatus. -Relates to a steelyard for weighing in two or more standards and consists in providing the sliding poise weight with a movable positioning nib so shaped that it can only be brought into co-operation with the various graduated faces of the steelyard when correctly set. As shown, the steelyard 3 has two bevel faces 4, 5 notched and graduated respectively to give readings in cwts and kilos. The positioning nibs 9, 10 are carried on a pin 6 projecting from the end of the poise weight 1, and have a dovetailed extension 16 which bears against one side or the other of the steelyard. The threaded portion of an operating knob 8 extends into a recess 15 in the pin 6 to limit rocking movement of the nibs. To change to the second weight system as given upon the bevel face 4, the poise is moved to the extreme right of the steelyard until the dovetailed extension 16 clears the end thereof after which the nibs are rocked upon the pin 6 within the limit of the recess 15 so as to bring the nib 10 over the notched face 4. If the operation be correctly performed the side 16<b> of the extension 16 will clear the side 17 of the steelyard and the poise may be returned along the steelyard for correct co-operation with the bevel face 4.

Title: Method of joining a carbon body to another body
IPC: C04B37/04
Filed: 1966-01-24
Abstract: In soldering a carbon body to another body a diffusion inhibiting barrier layer comprising a carbide is provided on the face of the carbon body and solder is applied to the barrier layer. Graphite may be joined to graphite, silicon carbide quartz or quartz glass and the barrier layer may be of one or more of titanium, zirconium, niobium and silicon carbides while the solder may be one or more of titanium, zirconium and niobium silicides or of silicon. The carbide layer may be formed by applying a layer of metal silicide on to the graphite face and subjecting the latter to heat so that the silicide reacts with the graphite to form a carbide and a metal silicide solder together with up to 50% by weight of a metal carbide may be applied in powder form.  In an example in which the end of a graphite tube is to be closed by a flat graphite wafer or by a graphite body having a spigot entering the end of the tube, the faces of the tube and closure body to be joined are coated with a suspension of titanium silicide in a 2% polyvinyl solution in water and are heated to 1700 DEG  C. in argon for 1 hour to convert the silicide into silicon carbide and titanium carbide.  The closure bodies are then coated with the suspension of titanium silicide, mounted on the tube, dried and heated to 1600 DEG  C. in argon for 1/2 minute. missing page 114

Title: Improvements in or relating to screw-cutting lathes
IPC: B23G1/04

Abstract: 674,656. Screw-cutting lathes. MASCHINENFABRIK HEID AKT.-GES. Feb. 14, 1950 [March 2, 1949], No. 3726/50. Class 83 (iii). A lathe having a lead-screw and a feed shaft driven from the headstock spindle, the feed shaft driving a pinion which co-operates with a rack on the lathe bed, is characterized in that an additional gear train is interposed in the gear drive connecting the headstock spindle to the pinion to enable the saddle to be fed at the same rate of feed by the feed shaft as by the lead-screw. The feed shaft drives through bevel gears 2 a worm and worm wheel 3, 4, carried by the saddle. This drive may be connected to the cross-traverse screw by sliding a pinion 5 on the shaft of the bevel wheel into mesh with a pinion 16. The pinion 5 when disengaged from the cross-traverse train may be engaged with a wheel 6, Fig. 2, and a pinion 7, secured to the same shaft as this wheel, may then be engaged to drive the rack pinion 9 for the saddle feed movements by sliding the wheel block 8, 14, to engage gears 7 and 8. When the wheel block is moved in the opposite direction, wheel 14 engages a wheel 13 forming a block with wheel 12, the latter is driven by a wheel 11, also on the worm wheel shaft, and the saddle is thus fed at the same rate as that given by the lead-screw, thus enabling the feed shaft to be used for the initial roughing cuts of a screw-cutting operation.

Title: Improved bristles and method of treating bristles
IPC: A46D9/06
Filed: 1934-02-05
Abstract: 426,747. Brushes. TELLER, W. K., 31, North State Street, Chicago, U.S.A. Feb. 5, 1934, No. 3791. [Class 19] A method of treating brush bristles to render them impervious to water and hence becoming soft, comprises covering the bristles with a water-insoluble soap with or without waxes or combinations thereof. According to one method, the bristles are dipped into a solution of a heavy metal salt, for instance aluminium, and subsequently into a 14 per cent acetate soap solution. The bristles are removed and excess solution drained or centrifuged off. The strength of the soap solution may be varied, and any soluble metal salt of a non-injurious character may be used. The impregnation of the bristles with an insoluble soap may be accelerated by an electrolytic method in which the bristles are first matted and wetted with a saponaceous compound and then passed through roller electrodes while spraying the matted bristles with an aqueous solution of a heavy metal salt. In such an example, 1600 parts of aluminium palmitate are dissolved with gentle heat in about 7200 parts by weight of hexahydro-phenol. In a separate step, 800 parts by weight of white ceresin wax are melted and added to 5,400 parts by weight of carbon tetrachloride. The aluminium palmitate solution in the hexa-hydro-phenol is then added to the wax solution together with 20,000 parts by weight of carbon tetrachloride and 7000 of naphtha. The mixed solutions are steam heated until a fairly thin solution results, which may be left standing. Bristles are immersed 30 minutes in this solution and drained for not over 5 minutes, and then dried between 100 and 110‹ F., for 4 or 5 hours. In another modification, Chinese and Japanese beeswax or other wax may be dissolved in xylene or other light organic solvent and the solvent allowed to evaporate.
