Title: Gauges for use with chaser-holders for screw-cutting die-heads
IPC: B23G5/12
Filed: 1935-12-07
Abstract: 444,468. Screwing die-heads. HERBERT, Ltd., A., DRANE, H. A., and MALLINSON, H., Canal Road, Edgwick, Coventry. Dec. 7, 1935, No. 33957. [Class 83 (iii)] A gauge for setting tangential chasers in a die-head comprises a bell-crank lever 19 carrying a pivot 20 which is inserted in a bore 18 in the chaser carrier 11. One arm 22 of the lever is provided with a face 21 lying in the plane of the first full tooth 23 of the chaser 12 when the pivot 20 is fully home and the other arm carries a screw 24 engaging a machined surface 26 on the carrier. The chaser is held in the carrier by means of a clamp 14 and screws 15 and in order to adjust the chaser the screws 15 are loosened and the chaser moved by a backing- screw 16 until the cutting end firmly engages the face 21 with the screw 24 firmly engaging the face 26. Graduations on the head of the screw 24 and a zero mark on the carrier provide for setting the chasers with their cutting ends exactly on the centre of the work or a predetermined number of thousandths of an inch on either side of the centre, as required by the material of the work. Specifications 391,526 and 391,527 are referred to.

Title: Improvements in or relating to the refining of copper and other metals
IPC: C22B15/14
Filed: 1930-11-11
Abstract: 367,384. Melting and refining metals ; endless chain conveyers. McGREGOR, A. G., Selection Trust Building, Mason's Avenue, Coleman Street, London. Nov. 11, 1930, No. 33983. [Class 82 (i.).] A process for the melting and refining of copper and other metals comprises causing a mass of metal to be melted to advance at a predetermined regular rate through a preliminary heating zone of a furnace to a melting zone, directing a heating flame directly upon the head of the advancing metal in the melting zone so that the metal is melted away in the melting zone at the same rate as that at which it is advanced thereto and employing the gases from the melting flame to heat the preliminary heating zone. Preferably the heating zone 12 is disposed horizontally and the metal in separate masses 13 on a chain or like conveyer 16 which is provided with carrier blocks 17 and pusher blocks 18 extending upwardly through longitudinal slots in the floor of the heating chamber. The charging end of the furnace has a slidable door 19, and a slidably mounted box 20 is provided actuated by an hydraulic ram 21 working in a cylinder 22 the door and box constituting an air lock which permits of the introduction of the piles of metal without admitting air into the furnace. The melting zone 23 has a sloping floor 24 with water cooled skids 25 on to which the metal is pushed by the conveyer. Fuel burners 26 direct flames which may be oxidizing in character to play upon the advancing metal. The molten metal is directed into an oxidizing or holding furnace 31 heated by a burner 32, and connected by a launder 34 to a reducing furnace 33 also provided with a burner 35, where copper may be poled and cast through an outlet 37. The gases from the burners in the melting zone proceed along the heating chamber and pass through an outlet into a recuperative air heater 28 where the air for the burners is preheated before use. The waste gases from the reducing furnace 33 are led through a flue 36 into the heating chamber. The invention may be employed for the refining of blister copper which is subsequently cast into plates by a casting machine located in front of the reducing furnace. Specifications 109,419, [Class 51 (ii), Furnaces and kilns for applying &c.], and 367,013, [Group XXXVI],. are referred to.

[Class 125 (iii).] A bottle &c. with a crimped cap and cap remover adapted to lie against the side of the vessel and having end projections pivotally engaging recesses in the rim of the vessel is constructed so that the recesses are positioned outside the annular area of the rim of the vessel which forms the sealing area. The opener 15 is formed with spring arms having the extremities 16 bent substantially at right-angles but slightly downwardly and inwardly so that the fulcrum for each arm is the end 19. The recesses are bounded by radial walls 11, 12, the walls 9 being formed at right-angles to a radius of the bottle &c. located midway between the two recesses. The angle between the positions at which the edge of the opener bears on the cap rim should be, it is stated, not less than 60‹ for metal caps 0À01 in. thick, so that minimum permanent deformation results on opening the vessel. The wall of the neck may be recessed to accommodate the arms of the opener 15 and such recess may be undercut to put the opener into spring engagement with the bottle. The opener, forming a bail, may be used to suspend the used bottle for decorative purposes. Specification 322,077, [Class 125 (iii), Stoppers &c.], is referred to.

Abstract: 1,002,299. Moving coil relays-protective cut-out systems. ENGLISH ELECTRIC CO. Ltd. Oct. 5, 1961 [Oct. 11, 1960], No. 34743/60. Headings H2B and H2K. A moving coil electric relay has conducting paths on a disc-shaped rotor so as to form two series-connected multi-turn plot spiral coils having ports which pass through an air gap between the poles of a stationary magnet, the coils progressing in opposite senses so that all torque producing paths carry current in the same sense. The laminated insulating disc 12 has four superposed windings 12a . . . 12d thereon connected in series by conductors 13. Each winding comprises two oppositely wound series coils having turns which include a torque-producing path 15 and a return path 16 which does not pass between the magnet poles. The paths 15 are not radial but are " skewed " to prevent uneven torque on the disc and the paths 15 of windings 12a and 12c are " skewed " in the opposite direction to those of windings 12b and 12d so as to cancel out radial components of force. The disc 12 may rotate between the poles of a permanent magnet 19 (Fig. 2) or an electromagnet (Fig. 3, not shown) in series with the windings 12a . . . 12d. The connections to the windings are made through adjustable biasing springs 21, 22 and a " sealing " electromagnet 26, 27 can hold the contacts closed. A conducting disc co-operating with a breaking magnet may be mounted on the same spindle as the disc 12 or an aluminium disc 11 may be mounted on the disc 12. With the former breaking arrangement it is possible to couple the two discs 11, 12 by a ball and ramp freewheel device to allow quick spring return. In Fig. 4 (not shown) the relay windings 12a . . . 12d are connected to an adjustable short resistor for calibration purposes and a reverse connected fine setting potentiometer and two rectifiers connected in a push-pull circuit with the centre-tapped secondary of a transformer having a tapped primary for coarse current setting. In Fig. 5 (not shown) the windings 12a . . . 12d are centre-tapped (i.e. between windings 12b and 12c) instead of the transformer. moved to join contacts 45, 46. Rotation continues until arm 43 engages contact K8 whereupon rectifier 42 blocks the motor current. The motor is then reversed and returned to its original position by moving switch 44 to join contacts 45, 46<SP>1</SP>. The switch 18 is associated with lamps 50, 51, for illuminating parts of the display panel. Specification 1,002,306 is referred to.
