Abstract: 584,333. Lamp-holders. CORNERCROFT, Ltd., and RYCROFT, N. Sept. 14, 1944, No. 17567. [Class 38 (i)] An electric lamp fitting comprises a casing having a lateral flange with gaps through which - projections on a lamp socket or terminal insulator assembled together can be passed so that upon turning the assembly its lateral projections rest on the lateral flange of the body, means being provided to retain the assembly in position. Figs. 7 and 8 show the terminal insulator 3 and lamp socket 2 separately and assembled, respectively. Terminal insulator 3 has flanges 3a, a projection 3b, and connecting screws 4, and lamp holder 2 has flanges 2c which coincide radially with flanges 3a when the assembly is held together by screw 5. To insert the assembly in a casing 6 of a standard lamp as shown in Figs. 10, 11, the assembly is pushed up from below so that the projections 2c, 3a pass through gaps 6b in an internal flange and is rotated until the projections rest in recesses 6a in the flange. A cap 7 is then screwed on the casing 6 until a central projection 7a engages projection' 3b of the assembly. Sleeve nut 9 screwed on the lamp socket retains in position a shade 8 having holes 8a screened by a shrouding 6c. Modifications are described in which the assembly is retained in position by a battenholder through-the central projection of which is a passage for the leads, Figs. 13, 14, 15 (not shown) and in which in a hanging lamp the leads are clamped between the central projection of the cap through which 'they pass, and the projection on the assembly, Figs. 19, 20, 21 (not shown).

Title: Improvements in or relating to electric arc lamps
IPC: H05B31/00
Filed: 1930-06-06
Abstract: 358,542. Arc lamps. WHITE, A. E., 5, Quality Court, Chancery Lane, London.- (Sperry Gyroscope Co., Inc. ; Manhattan Bridge, Plaza, Brooklyn, New York, U.S.A.) June 6, 1930, No. 17639. [Class 39 (i).] The positive electrode is fed forward and rotated with a step-by-step motion, the length of the step being automatically controlled by the arc conditions ; arrangements for holding and feeding the negative electrode are also described. The positive electrode is held by two rollers mounted on a rotating head 40. The head 40 carries a pinion 42 engaging a fixed gear 43 and driving the rollers through a worm 45. The head 40 is rotated by gears 36, 37 and shaft 35. The shaft 35 carries a ratchet 34 driven by a pawl 33 on a reciprocating slide 28. Normally the pawl 33 is prevented by a piece 60 from engaging more than two or three teeth of the ratchet. When the positive electrode has burnt away too far an are is struck to an auxiliary electrode 61 completing the circuit of an electromagnet 62 which draws down the piece 60 and allows the pawl to engage a larger number of teeth and feed the electrode faster. The slide 28 also feeds and retracts the negative electrode through pawls 85, 86 engaging with ratchets 83, 84. The appropriate pawl is put into action by an electromagnet 93 in the arc circuit moving a ballcrank lever 91 against the action of a spring 94. To prevent the action of the electromagnet 93 from being disturbed by charges of temperature the winding is made of very low resistance and is connected in series with a resistance 95 having a low temperature coefficient. The ratchets 83, 84 drive the negative electrode N through a shaft 82, gears 81, 80 and a screw 72. The electrode N is mounted in a holder 70 pivoted to a carriage 71 and engaging the screw 72 by a piece 75, Fig. 7. A spring 113 holds the piece 75 in engagement with the screw 72 and passes the forward end of the electrode against a bearing 100 which also serves to supply current.

Title: Improvements relating to the introduction of mixing of one fluid into another
IPC: B01F5/04
Filed: 1944-09-18
Abstract: 593,750. Lubricators. WALKER, W. J. Sept. 18, 1944, No. 17810. [Class 12 (iii)] [Also in Groups II and XXIX] A device for introducing lubricant into the air conduit of a pneumatic rack drill comprises a pair of coaxial cylinders 1, 9, forming an annular reservoir 7 for the lubricant, and is connected in the air conduit by screw-threaded necks 2, 6, containing air passages 12, 13 respectively. The tube 9 is of lesser diameter than the passages 12, 13, so that a high pressure is produced at the passage 13 through which the air enters, whereby air is forced through a passage 17 into the reservoir 7 to force lubricant therefrom through a capillary passage 21 into the main air stream. The members 1, 9 are formed of two different metallic alloys of coefficients of expansion such that as the temperature rises or falls, the resulting variation in the viscosity of the lubricant flowing through the passage 21 is compensated by a variation in the crosssectional area of the passage so as to maintain constant the mass of lubricant which flows per unit of time. The passage 21 is formed between a flange 10 on the tube 9 and an end face 23 of the tube 1, and is adjustable in size by the insertion of shims 24 between an end face 25 of the cylinder 1 and a shoulder 26 of an end cover 5 attached by screws 16 to the tube 9. The passage 17 is formed by the insertion of shims 20 between a flange 11 on the tube 9 and the end cover 5. Specification 475,495 is referred to.

Abstract: 145,675. Siemens & Halske Akt.-Ges. June 30, 1919, [Convention date]. Transformers.-In a highvoltage transformer, the highvoltage winding is wound in layers separated by insulating- material, the axial lengths of the layers being graduated towards the outside of the winding in such a manner that the voltage drop along the periphery of the winding is nearly constant. The low-voltage winding 2 is wound on the core and is separated from the high-voltage winding by a tube 3. The end 4 of the high-voltage winding is brought to a low potential by earthing or by connecting it to the low-voltage winding. The first layer 4, 5 of the high-voltage winding is separated from the second layer 7, 8 by a layer of insulation, such as paper, and the second layer stops at a distance 9 from the beginning of the first layer. The third layer 10, 11 similarly stops at a distance from the beginning of the second layer, and so on. The thickness of the insulating- layers decreases from the inside to the outside in order to make the dielectric strain approximately the same in all the layers. The outer insulating layers are made a little thicker in order to protect the winding against wandering waves. Two highvoltage windings may be provided on the same leg of the core 1.

Title: Improvements in Classifying and Concentrating Apparatus for Minerals and the like.
Inventor: RICHARDSON WILLIAM WHITEHEAD
IPC: B03B5/56
Filed: 1916-12-27
Abstract: 107,927. Richardson, W. W. Dec. 27, 1916. Rotary washing-apparatus.-Ores, minerals, and like materials are classified and concentrated in an apparatus comprising two or more trommels arranged in series and having grooved or indented inner surfaces. When treating large quantities of material, groups of trommels, arranged in the manner shown in Fig. 2, may be used, the material being fed by a conveyer 50 and shoots 18, to trommels 10, 11, whence the various grades of classified material pass along trays or shoots 30, 29, 28 into trommels 12, 13, and 14 respectively. The trays extend to different distances within the trommels 10 and 11, as shown in Figs. 1 and 2. The right hand section 15 of each trommel serves as a disintegrating chamber and is supplied with water under pressure from a pipe 19. This section 15 is built up of segments formed with externally directed flanges by means of which the segments are bolted together. The internal surface of each segment is formed with a central longitudinal rib to assist in disintegrating the material. The rest of each trommel is built up of sections of successively larger diameters. Each section is formed of segments, which may be of glass or manganese steel, suitably flanged for securing them together. The inner surfaces of these segments are formed with a pattern of small rectangular, elongated-hexagonal, wedge-shaped, or other grooves or indentations, arranged in staggered form, to assist in selecting the values. The long axes of the grooves lie parallel to the length of the trommel, and, in the case of wedge-shaped grooves, these widen in the direction of flow of the material. Each trommel is slung by ropes from a driving-shaft 38, Fig. 4, the ropes 40 pass. ing round pulleys 37 and 36, each of which has several grooves. Longitudinal and lateral movement of the trommel is limited by longer ropes 41, which engage the pulleys 36 at each side and pass round pulleys 42. firmly anchored to the ground or foundation. During the rotation of the trommels, the values are carried round in the grooves, before mentioned, until they are washed off into the trays by jets of water sprayer from a closed trough 32 by a propeller-like apparatus 31. The cover 34 of the trough is adjustable to provide a variable gap 35 for the escape of the water jet.
