Patent GB-453273-A (GB)
Title: Improvements in and relating to the separation and recovery of metals
IPC: C22B5/00
Filed: 1935-01-04
Abstract: Raw material, containing volatile metals in free or combined form and compounds of non-volatile metals, is charged together with a reducing agent into a rotary electric furnace, having a heating resistance or resistances traversing the entire length of the furnace axially, in such manner that the charge does not come into contact with the resistance or resistances; the furnace is heated to a temperature such that melting of the entire charge is avoided but sufficiently high to cause volatilizing of the volatile metals; the charge is then melted by raising the temperature and reducing gases are circulated to obtain non-volatile metals in free or combined form or in the form of alloys by a reducing operation.  Between the volatilization and melting stages, the charge may be subjected to liquation or sweating. In the volatilization stage, the atmosphere may be oxidizing, neutral or reducing: gaseous or solid reducing agents may be used.  The non-volatile metals may be copper, lead, tin, bismuth, antimony, and the volatile metals, cadmium, zinc, arsenic.  The treatment may be applied, for example, to mixed zinc and copper ores containing lead, silver and gold, to flue dust, and to sulphur compounds of lead and zinc.

Filed: 1949-01-06
Abstract: 661,392. Processing photographic materials. ILFORD, Ltd. Jan. 2, 1950 [Jan. 6, 1949], No. 432/49. Class 98 (ii). A method of treating exposed photographic film or paper strip in roll form comprises embossing at least one of the margins of the strip to form lines, running the length thereof, of small protuberances above the film or paper surface, allowing the strip to coil on itself and treating it in that condition, and without any other support, in a tank of processing liquid. The axis of the coil may be vertical in the tank, and the embossed margins may be trimmed off after processing. The protuberances are preferably formed only on that side of the strip not carrying the emulsion, e.g. by feeding the margin of the strip between meshing gearwheels. The strip may be placed in the daylight loading chamber of a processing tank and passed between rollers which emboss the edges and on to the processing chamber. When the embossed strip is fed from one vessel to another in continuous processing equipment, the protuberances may engage feeding mechanism.

Title: Improvements in or relating to writing instruments
IPC: B43K7/08
Filed: 1947-01-06
Abstract: 669,973. Reservoir pens. HENRIKSEN, E. J. J. Jan. 6, 1947 [Jan. 5, 1946; Jan. 10, 1946], Nos. 451/47 and 452/47. Class 146 (iii). In a ball-point pen wherein a tubular reservoir 3 has an air inlet 5 at the opposite end to the ball-tip 9, there is disposed between the column of ink 7 and the air inlet, a plug 6 consisting of a layer of liquid or a viscous or pastelike substance such as a thickened mineral oil, which does not mix with the ink and which prevents contact between the air and the ink. The consistency of the plug may be such as to prevent ink escaping from the reservoir. The colour of the plug may be different from that of the ink so that approaching exhaustion of the reservoir is indicated when the writing changes colour. According to the Specification as open to inspection under Sect. 91, the plug may consist of a paraffin composition or of a substance having the same viscosity as the ink or may be made of light metal. Alternatively, it may be constituted by or provided with a permanent magnet, and a ring of ferro-magnetic material may encircle the outside of the barrel; the ring follows the plug and thus indicates the level of the ink. The following constructions also are described : (1) The reservoir 3, Fig. 1 (Cancelled), is slidably mounted in an outer casing 1, and has a tubular ball-point section 8 projecting through a tapered end 2 of the casing. The end of the reservoir is closed by a lid 4 provided with an air vent. A pin 10 is pressed against the lid 4 by a spring 11 housed in an air-tight cap 12 fitted to the end of the casing 1. Air is admitted to the vent in the lid via the space between the parts 2, 8, grooves in a seating 15, and a narrow longitudinal channel between the parts 1, 3. The lid 4 may be air-tight and the chamber between it and the plug may contain a gas under pressure. (2) The reservoir may be constituted by a number of longitudinal passages joined in series by recesses in end pieces. (3) The tubular point-section 8 may be curved to enable the pen to be held inclined to the paper instead of vertically during writing. (4) Two curved ball-point sections each communicating with its own reservoir may be provided at one end of the pen. (5) A barrel may have a ball-point section at each end fed from separate reservoirs provided with a common air-intake at the centre of the barrel. (6) The reservoir 3, Fig. 15 (Cancelled), may be slidable against the action of a spring 36 in an outer casing 1 having a cap 35 carrying a rod 37 extending into the reservoir with a piston 38 at its end. Pressure on the ball-point causes relative movement between the piston and the reservoir to set up pressure above the plug 6 and on the ink column 7. In a modification, a spring-retracted knob is mounted in a recess at the end of the cap and the recess communicates with the reservoir by an air duct. When the knob is pressed inwardly, pressure is applied to the ink. This subject-matter does not appear in the Specification as accepted.

Moulding wheel tyres.-In means for producing a shaped tyre casing from a flat band, one edge of the band is held against a fixed abutment towards which the other edge is pressed whilst the mid-portion of the band is foreed radially outwards. In the apparatus shown, the band 47 is fitted over a drum formed by the rings 21, 22, 23 between stop-rings 28, 29. The ring 29 is held stationary by the hooked ends 32 of arms 3 which are pivoted to the base 1 and adjustably linked to a movable head 9. The ring 28 is carried on a drum 17 which is fitted on a flange 14 of a cylindrical plunger 11 which can be raised by pressure-fluid admitted at 13. The plunger 11 is fitted with racks 27 which, through pinions 25, engaging the fixed racks 26, transmit a slower movement to a spider 24 supporting the drum member 21. An inflatable tube 34 mounted on the ring 22 is used to distend the band 47 and, owing to the differential movements of the cylinder 11 and spider 24, this distending pressure is applied throughout at the centre of the band. At the end of the upward travel, split rings 30, 31 snap into grooves 48 in the ring 22, which can be removed with the shaped casing and tube 34 for the finishing operations. The plunger 11 having been lowered, the arms 3 are swung radially inwards to clear the drum structure, which is then removed bv the tackle 38. The machine is adapted for shaping tyre casings cf various sizes by the substitution of graded rings 17 and drums. The drum elements may have pin-and-slot connexions 45.

Abstract: 563,860. Seaming non-metallic sheet material. BRITISH CELANESE, Ltd. (Celanese Corporation of America). Jan. 13, 1943, No. 639. [Class 42 (i)] [Also in Group XI] Pieces of textile fabric, at least one of which consists of, or contains, thermoplastic material, are joined together edge to edge by bringing together surfaces of marginal portions of the fabric adjacent the edges, and, at a series of spaced positions within the area of contact, heating the fabrics so as to render the thermoplastic material adhesive and attach one of the pieces of fabric to the other at the said positions. Two lengths of fabric, one or both of which contains thermoplastic material, e.g. cellulose acetate, can be joined by overlapping the ends and heating the fabrics at spaced positions within the area of overlap or two lengths of non-thermoplastic textile fabric can be joined by placing a strip of thermoplastic material over the abutting edge of the fabric and heating the assembly or a strip of foil, film, or textile fabric consisting of or containing a thermoplastic material may be interposed between the overlapped marginal portions of the fabrics, e.g. of cotton, to be joined together. The heating may be effected by a wire coil 18 disposed in a spiral groove in a roller 11 of ceramic or other suitable material carried by a shaft 9 mounted in bearings in the arms 7 of a handle 1, the coil projecting beyond the grooves and the ends thereof being connected to leads 2 through a switch 3. The roller is preferably formed of a number of discs clamped, together with metal end discs 16, on the shaft 9 by nuts 13 and the ends of the wire 18 are secured to the discs 16, brushes 31, contained in housings 27, being pressed by springs 32 against the discs and being connected to the leads 2 through bushings 33. The pieces of fabric may be pierced by the heating device so as to melt the thermoplastic material thereof and produce a series of holes or slots with sealed edges and the position at which the pieces are attached may form a regular pattern which may comprise a parallel series of points or short discontinuous lines angularly disposed across the width of the fabric. Specifications 452.296, 466,562, 474,053, 474,496, 475,003, 482,301, 493,066 and 502,701 are referred to.

Abstract: 441,430. Compensating for wear in brakes. MOLD, A. W., 3, Wharncliffe Road, East, and McINNES, J. H., 45, Bective Street, both in Liverpool. Jan. 9, 1935, No. 718. [Class 103 (i)] Adjusting means for brakes of the kind in which application and release of the brake is effected by the longitudinal movement of a cam connected to a longitudinally - moving applying member are operated by angular movement of the applying member into which a part of the longitudinal movement of the member is converted. The cam may have an oval cross-section so that it serves also as the adjusting means or a separate adjusting cam may be provided. The cam 57 engaging the brake shoes 10 by rollers 58 is given a longitudinal movement by the applying member or rod 59 which slides in a fixed casing 60. The cam 57 is of oval cross-section. The rod 59 has a pin 70 engaging a helical groove in a slidable block 62. When the rod is moved to the right to apply the brake, the block moves with it and if the movement is excessive, a pawl 64 engaging a rack on the block abuts on a stop 68 so that the pawl slips a tooth. On the return movement the block is held by the pawl when it returns to its position against the part 67 of the casing and the further movement of the rod 59 results in an angular movement thereof and of the cam and an adjustment of the shoes 10. In a modification, the rack and pawl are omitted, the angular movement of the rod and cam being effected during the application movement. In Fig. 6, the angular movement of the rod 59 which carries the brake applying cam 85 operates through linkage 86 a separate adjusting cam 84 which engages the opposite ends of the shoes 80. The cam 85 may be conical or it mav be of oval cross-section so that adjustment of the shoes is effected at both ends. Indicators, applications of.-To indicate when the friction linings of the shoes have been worn to a predetermined extent, a casing 26 fixed, for example, to the dashboard of a vehicle, contains a vane 28 normally visible through an aperture 27. The vane is pivoted at 29 and has an arm 30 resting upon a cam 31 connected by a cable 25 to the brake applying rod 59. When the adjustment of the shoes reaches the predetermined limit, the cam is turned and the vane moves away from the aperture 27. The vane may also close the circuit of a bell 34 through a contact 35. The cable may instead actuate a mercury switch in the circuit of a lamp or bell or the liquid instead of being mercury may be a solution and the contacts such that when the liquid covers the contacts a permanent metallic bridge is built between the contacts.
