Patent GB-311792-A (GB)
Abstract: 311,792. Fennell, W. Jan. 17, 1928. Installation conductor arrangements.-For pro. tecting domestic and like installations each conductor CC, Fig. 1, or the conductors as a whole are surrounded by a sheath of metal foil or braid S lightly insulated by an outer covering R (which may be lead-covered) or by a tough rubber covering. The sheath is connected to earth E through an indicator or through an electromagnetic device so that in the event of a fault to earth the indicator operates or the electromagnetic device operates to cause the rupture of the main fuses. To facilitate connection of the sheath a conductor W is laid alongside and in intimate contact with it. In the first form shown in Fig. 4, in which the supply through the fuses MF is divided into two branches, the sheathing also (by means of bonding fittings) and indicators d, d<1> are located in the branch sheaths to operate with less leakage current than the main indicator D. The branch leads and the corresponding sheaths are made accessible at the far ends so that by applying an artificial fault the system may be tested. In the combined overload and fault arrangement of Fig. 3 the earth fault current passes through the coils of a relay device and by attracting the latch a releases the arm g, whereupon the plunger p rises and mechanically fractures the main fuse f. Alternatively, the plunger may be insulated and connected to the opposite pole of the circuit, so that when it engages with the fuse wire it puts a dead short-circuit on it.

Title: Improvements in honing machines
IPC: B24B33/02
Filed: 1965-07-26
Abstract: 1,039,066. Honing. P. NAGEL. July 26, 1965 [July 24, 1964], No. 31705/65. Heading B3D. A machine for honing an internal or external cylindrical surface is provided with control means responsive to the diameter of the cylindrical surface for causing reversal of the stroke of the honing tool to limit the stroke to the region of a high spot. The honing head is reciprocated by an hydraulic actuator 6, 7, Fig. 1, supplied by a pump 11 through a solenoid distributing valve 9. A dog 16 on the honing head co-operates with limit switches 14, 15 on the machine frame to effect reversal at the ends of the stroke, the magnitude of the stroke and its position relative to the workpiece W being determined by adjusting the limit switches in the direction of the stroke. The honing tool spindle 2 is rotated by an hydraulic motor 5 supplied by a pump 21 through a solenoid on-off valve 22. A pressure switch 25, 26 is connected to the line 24 between the valve 22 and motor 5. When the honing tool reaches a high spot, the pressure in the line 24 rises; as the tool leaves the high spot the pressure falls, the contacts 26 close and a control device 13 passes an impulse to the valve 9 causing immediate reversal of the stroke. Short stroking continues until the high spot has been removed. In a modification, Fig. 2 (not shown), a pressure switch 31, 32 is connected to the line 30 between the pump 11 and valve 9. The motor 5 rotating the honing tool spindle is hydraulic or electric. In a modification, Fig. 3 (not shown), the honing tool spindle 2 is rotated by an electric motor 5 the circuit of which contains a currentresponsive electromagnetic switch 40 whose armature 41 actuates contacts 42. As the honing tool leaves the high spot the current taken by the motor 5 falls, the contacts 42 close and an impulse is passed to the valve 9 to reverse the stroke. In a modification, Fig. 4 (not shown), the honing tool is provided with a pneumatic diameter gauge device. A line 50 supplying air to the orifices in the honing tool is connected directly to a bellows 53 and through a restriction 54 and an accumulator 55 to a bellows 52. As the honing tool leaves the high spot, the pressure in line falls; the pressure in bellows 53 drops immediately, but the pressure drop in bellows 52 is delayed. Thus an indicator pointer 57 is moved, contacts 58 close and an impulse is passed to the valve 9 to reverse the stroke.

Abstract: 1,134,239. Making heat exchangers. A.P.V. CO. Ltd. 23 June, 1967 [14 July, 1966], No. 31714/66. Heading B3A. A cell for a heat exchanger is made by inserting a group of tubes 4 through aligned apertures in plates 1, securing the tubes to the plates, and cutting the tubes in alternate spaces between the plates. The tubes are preferably brazed to the plates in a salt flux bath or a vacuum furnace. The plates and tubes may be stainless steel, aluminium or any brazable metal or alloy. The plates are perforated unsymmetrically so that when the cells are assembled in a casing 8 the tubes of adjacent cells can be offset by inverting alternate cells. The tubes may be inserted in the plates when the plates are spaced on a jig or when they are together and spaced after the insertion. The spacing of the plates is such that the adjacent plates of a pair of cells are spaced sufficiently to admit a bandsaw blade. The cells are tested for leaks hydrostatically and are spaced in the casing 8 by gaskets, or by flanging one plate, and welding the plate to the adjacent cell. The pitch of the apertures may be triangular or rectangular.

Filed: 1973-07-04
Abstract: 1405809 Electrolytically oxidizing cyanide RISEFIELD Ltd 21 June 1974 [4 July 1973] 31926/73 Heading C7B Spent salts used as melts for surface hardening Fe are dissolved in water and electrolyzed to oxidize their CN content using at least one insoluble anode, e.g. of graphite or platinized Ti, and at least one soluble anode comprising Zn, Al or Sn. The salts contain essentially Na 2 CO 3  and 10-15% NaCN with other salts/materials. The soluble anode may be Zn dross from hot-dip galvanizing, scrap Sn-plate or scrap Al from an anodizing plant; the Zn or Sn may be cathodically recovered as metals while Al is recovered as NaAlO 2  and Al(OH) 3 . The anode may comprise a permeable Fe or Ti basket containing the scrap, although pre-formed electrodes may be used. A batch or continuous electrolysis is suitable. In the former case the final traces of CN are removed chemically e.g. by adding NaOCl. The continuous process may be a closed loop in which the dissolved salts are electrolyzed, the electrolyte passing to a recovery stage where e.g. Na 2  CO 3 . 10H 2 O crystallizes and the spent electrolyte is recycled for dissolving fresh salts. Gases evolved in the electrolysis may be scrubbed to recover NH3 (as aqueous solution) while H 2  and O 2  may be recovered by diaphragm techniques. The salts may be supplied in drums or the electrolysis process may be connected direct to an overflow wier from the Fe surface hardening step. Solid impurities in the salts e.g. BaCo 3  are recovered by filtration of the solution before electrolysis. Additional cyanide containing waste, e.g. Zn CN sludge from an electro-plating bath, may be added to the spent salts for simultaneous treatment therewith.

Title: Improvements in cutting machines for use in connection with the joining together of pieces of leather
IPC: C14B5/00
Filed: 1919-12-19
Abstract: 147,400. Henriksen, L. J. Dec. 19, 1919. Cutting - apparatus with milling - cutters; grooving.-A machine for shaping the ends of leather to be joined as shown in Fig. 4 comprises a milling cutter of corresponding shape and a feed - wheel straddled by an endless belt between which and the feed-wheel the leather is fed to the cutter. The cutter comprises portions 3, 5, 4 for cutting, respectively, the groove, the top of the shoulder, and the edge of the work. The work 12 is fed between an endless belt 7 and a feedwheel 6, the belt being kept tapt by means of a resiliently - mounted pulley 8. The bearings of the feed-wheel 6 are carried by a spring-raised slide 15, the upward pressure of which is transmitted through a double toggle or equivalent mechanism to a pressure roller 22 which is thereby depressed on to the belt 7 with equal pressure. This mounting of the parts allows for an automatic adjustment to meet the requirements of work of varying thickness and ensures that the plane through the middle of the work remains constant. The initial position of this plane is controlled by an adjusting screw 38. A stop 21 serves to limit the ascent of the slide 15 and so prevent the feed-wheel from fouling the cutter. A presser-foot 40 mounted for movement with the pressure-roller 22 serves to depress loose edges of the work and a suction pipe 41 connected with a fan removes the waste material.
