Title: Improvements in and relating to ferrous alloys
IPC: C21D8/00
Filed: 1928-07-17
Abstract: 302,644. Browne, V. B. Dec. 19, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Drawings to Specification. Wire, ribbon, and tape; electric fittings. - Iron-chromium-aluminium alloys, especially such alloys containing 5-30 per cent chromium and 3-10 per cent aluminium, the remainder being iron with as low a carbon content as possible are worked from the ingot by forging or rolling in a series of stages each of which is completed at a temperature lower than that of the preceding stage. The final reduction is effected at a temperature below 1400‹ F. and is preferably carried out while the work is cold. The finished work is annealed at a temperature below 1150‹ F. The process is stated to yield strips, wire, light gauge sheets, &c. which are ductile and which resist oxidation at high temperatures. The application of such products to the manufacture of soft, ductile resistance grids is indicated. The alloys may be manufactured in an electric arc furnace, the aluminium being added just before teeming. Numerical data of a particular example of the process of working are given in the Specification. Claims are made for a soft, ductile product, such as a resistance element having given chemical compositions.

Abstract: 1525081 Hydraulic presses J A PAWLOSKI 19 May 1976 20770/76 Heading B5F [Also in Division B3] In a fluid pressure operated crimping shearing, &c. tool controlled by a valve 42, means is provided for preventing re-setting of the valve to reverse the stroke of a piston 25 unless the operating fluid is at least at a predetermined pressure sufficient to complete a working stroke. As shown, the piston operates the crimping jaws 18, 19 against the influence of springs 24 by means of a cone 27. A holder 13 for the jaws is screw-threaded on to the body of the tool and carrier a holder 52 for wire on to which a terminal is to be crimped. Operation of a lever 47 to set valve 42, Fig. 2 (not shown), supplies compressed air through ports 38, 39 to start the piston 25 on a working stroke, against the influence of a return spring 48. At the end of this stroke a port 32 in a bleed tube against which the piston seals 34 is uncovered. Compressed air enters the tube through the port 32 and is returned to the valve 42 which it re-sets by pressure against the end of the valve so that the ports 38, 39 are opened to exhaust 40. 1525086 Extruding coated cores CENRUS AG 21 Jan 1977 [22 Jan 1976] 02470/77 Heading B5A In a process for the continuous coating of wire or hemp materials for the polymerization of an activated laurin-lactam are fed in direction of arrow 1 into the heart-shaped, non- turbulent mixing chamber 9 where the turbo mixer disc 10 directs the mixture into the mould passages in direction of arrow 5.

Patent GB-369120-A (GB)
Title: Process for the recovery of nickel and cobalt or pure salts thereof
IPC: C22B23/00
Filed: 1931-07-22
Abstract: Ores or metallurgical products containing nickel and cobalt are first subjected to a dry concentration process to separate copper, lead, iron, and noble metals as a matte and to form a concentrated speiss containing nickel, cobalt, arsenic, and antimony, and the speiss then finely ground and decomposed by strong sulphuric acid, say at 200 DEG C., without previous roasting and with or without pressure, whereby arsenious and antimony oxides and sulphates of the metals are formed, the latter being leached out with water say at 40-50 DEG  C. and the former being left in the residue.  Sulphur dioxide evolved during the latter reaction may be recovered.  The concentration of crude speiss may be effected by fusing in admixture with sulphur, whilst crude matte may be fused with products containing arsenic to separate nickel and cobalt as a concentrated speiss.  The decomposition by sulphuric acid may be effected with agitation in cast-iron pans using excess of acid to retain the mixture mobile after reaction is complete.  The mass is continually stirred until cool and then filtered, the excess acid being returned to the process. Specification 368,316 is referred to.ALSO:Ores or metallurgical products containing nickel and cobalt are subjected to a concentration process to separate copper, iron, lead, and noble metals as a matte and to form a concentrated speiss containing nickel, cobalt, arsenic, and antimony.

Title: Hand drying apparatus
IPC: H01H35/00
Filed: 1957-07-03
Abstract: In order to avoid the use of a foot switch or touching a switch with wet hands, an electrical hand drier is switched on by blowing, through an aperture in the casing, against a light vane, the resultant movement of which actuates a switch.  This brings a timing switch into operation and allows the drier to function for a predetermined interval.  The vane is blown back to its initial position, for subsequent use, by part of the air from the electrical blower.

Title: Improvements in or relating to piston-type hydraulic shock absorbers

Filed: 1935-07-31
Abstract: 460,851. Hydraulic shock-absorbers. NEWTON, N. B. July 31, 1935, No. 21685. IClass 108 (iii)] In a hydraulic shock-absorber of the piston- and-cylinder type having a valve or other internal adjustable part movable relatively to both the piston and cylinder for controlling the flow of liquid, adjustment of the valve &c. is effected by relative longitudinal movement and /or rotary movement of the piston and cylinder other than normal, which first effects engagement of the valve &c. with a relatively fixed internal part and subsequently varies the position of the valve &c. Fig. 1 shows a portion of a hydraulic shockabsorber in which the piston carries an adjustable screw valve a formed with a projecting square end c adapted, when adjustment is to be effected, to engage a similarly-shaped socket h in the head of a screw g carried by a plate f fixed in the cylinder, subsequent relative rotation of the piston and cylinder causing axial movement of the valve a. In a modification, the upper end of the valve a is roughened, serrated, or formed with spikes to engage a rubber pad fixed relatively to the cylinder. Fig. 3 shows another construction in which the valve a is arranged horizontally and its head adapted to engage an annular serrated or rubber-covered member n. In a modification the valve-head is adapted, on rotaton of the piston from normal position, to engage a vertical serrated, or rubber-covered arm, adjustment being then effected by axial movement of the piston in the cylinder. A portion of a further shock-absorber is shown in Fig. 5, adjustment in this case being effected by a slot 38 in a cap 36 co-operating with a rib 19 on a fixed stud 15, relative rotation of the parts causing axial movement of the cap to vary the spring-loading on a valve 33 which controls flow of liquid through a conduit 34, 32, 35, 37 on extension of the shock-absorber. Liquid displaced by the entrance of the pistonrod in the cylinder on compression of the shock-absorber passes to a compensating chamber through a restricting orifice 18 in a valve disc 17 slidable on the stud 15, the valve 17 moving downwardly on extension of the shock-absorber to allow comparatively free flow of liquid.
