Title: Improvements relating to direct current electric generators
Inventor: SIMON ROBIN HOWARD SALIS
IPC: H02K23/24
Filed: 1958-06-06
Abstract: 857,034. Exciting dynamo-electric machines. ENGLISH ELECTRIC CO. Ltd. June 4, 1959 [June 6, 1958], No. 18120/58. Class 35. To overcome the effects of saturation the interpole excitation of a separately-excited generator Ga is caused to increase more rapidly than the load current passing through its series excitation winding Gs by the use of an additional separately-excited winding Gc. The generator is caused to feed constant power to motors M1 to M4 by a regulator TR which reduces the generator field Gm as the load current rises, and since the interpole windings Gs and Gc are in opposition, this causes a disproportionate increase in the interpole excitation.

Title: Improvements in and relating to units for textile machines for drawing and feeding textile fibers
IPC: D01H5/74
Filed: 1935-06-27
Abstract: 457,937. Rollers. CUTLER, R. W., 6, Arlington Street, Boston, U.S.A. June 27, 1935, No. 18401. [Class 42 (ii)] [See also Group IX] Rollers for drawing or feeding textile fibres are provided with a surface layer having as an essential constituent a base of synthetic rubber of the polymerized halogenated acetylene type. The invention is described with reference to the drawing-apparatus described in Specification 373,193, [Group IX], and as applied to the upper rollers thereof consisting of bosses b provided with cots or covers e. A suitable composition consists of synthetic rubber, such as chloropene, 100 parts by weight, soft gas black 50, magnesium oxide 10, zinc oxide 10, rosin 5, phenylbetanaphthylamine 0À5. Preferably, the proportion of the synthetic rubber is not less than 16 per cent or more than 65 per cent of the compound, and the proportions of the first three compounded with the synthetic rubber should be such that the hardness after curing, vulcanizing or polymerizing, as measured by a Shore durometer, is between 10 and 90, although it may be as low as 22 and, for feed rollers, as high as 95. Diluents may be added such as natural rubber or, preferably, an acetylene polymer. Cork dust or other filler may be added. Rollers for drawing or feeding fibres formed from these compositions have a high resistance to abrasion, may be buffed and, so finished have no tendency to pick up lint, are unaffected by oil, water, mild acids, or weak alkalies and do not become slimy when used in wet spinning or twisting. A composition such as that given above with 5-10 per cent of cork dust and hardened to 70-75 is suitable for the top rollers of spinning, twisting, drawing, carding, combing, and like machines ; without the cork dust and hardened to 95-97 for the feed rollers of such machines and of coilers, spoolers, warping machines, slashers, lap machines and the like. The carbon black may be replaced by blanc fixe, aluminium flake, diatomaceous earth, litharge, pumice, talc, or other material if a black colour is not desired. The odour of chloroprene may be destroyed by treating it in its simple, polymerized, or cornpounded form with an alkaline substance of the nature of triethanolamine having the formula (C2H4OH)3N in the form of a gas, vapour, or liquid, or deodorants such as musk, lavender, ginger root, sassafras, mint, and the. like may be used. The composition may be extruded in tubular form suitable for roller covers, or made in the form of sheets, or may be sprayed in liquid form on fabrics, or fabrics may be impregnated therewith by vacuum or pressure systems, or by soaking.

The insulated conductors each comprise a tube 16 of pure metal, e.g. aluminium or copper, cooled by helium 17, with wires 18 of super-conducting material and insulation tape 20. Steel wires 19 may also be included. In another embodiment strands formed of the super-conducting wire are disposed on the surfaces of the steel wires and in a further embodiment the wires of superconducting material are replaced by a layer of super-conducting material on the tube 16. The conductors are held together by bands 22 and are suspended within the screen by wires 23 having low thermal conductivity. The screen 24 is suspended by filaments 36 from the cover 31 of the enclosure 30 which contains a thermally insulating powder 38 and cooling ducts 26 containing liquid nitrogen 27. A duct 35 in the cover exhausts the air from both the enclosure 30 and the screen. A plate 28 may be provided to protect the conductors from any liquid oxygen which may result from a leak in the enclosure 30, if the plate is omitted only the lower part of the screen is perforated.

[Class 100 (i).] A weft - straightening device for woven fabrics comprises pairs of rollers arranged in parallel planes, alternate pairs being in the same plane and staggered with respect to the pair or pairs in the other plane, and means for simultaneously varying the mutual angularity of the rollers of each pair in the same manner in their respective planes so that the common tangents between successive rollers are increased at one end whilst being decreased at the other end. As shown two pairs of roll ers 2, 3 and 6, 7 and an intermediate pair 4, 5 are arranged in vertical planes and, in their normal condition, the axes of the rollers are parallel to one another and the pair 4, 5 is staggered with respect to the pairs 2, 3 and 6, 7. Guide rollers 1, 8 in stationary bearings are also provided and the fabric passes round the rollers as shown. The rollers 2-7 are mounted in bearings g slidable on guide rods b, c. At each end of the rollers is arranged a pair of vertical rods i, j connected by rods k to the opposite ends of levers l arranged on a cross-shaft m which may be rocked by a handle n or by chain-actuated worm gear so that as the rods i move upwardly the rods j move downwardly. The bearing brackets g of the rollers 2, 4, 6 are, at one end of the rollers, connected to the rod i and at the same end, the brackets of the rollers 3, 5 and 7 are connected to the rod j. At the other end, the brackets of the rollers 2, 4, 6 are connected to the rod and those of the rollers 3, 5, 7 to the rod i. Thus, as the shaft m is turned the push of the fabric at one end of the rollers is extended and at the other end is reduced.

Title: Dental forceps

Filed: 1938-06-22
Abstract: 516,180. Dental forceps. BUSKIRK, E. E. June 22, 1938, No. 18589. Convention date, June 24, 1937. [Class 81 (ii)] A dental forceps has a pair of outer beaks 6, 7, Fig. 1, having rounded tips 8a, Fig. 3, adapted to engage the alveolar process on opposite sides of the tooth, and inner tooth-engaging beaks 8, 9 slidably mounted in .recesses 14 in the outer beaks. The inner beaks are -pressed down by .springs 15 so that their points lie within and above those of the outer beaks, and the recesses 14 diverge upwardly from one another at an angle of 20‹-40‹. In operation, the forceps are applied as shown in Fig. 1 and oscillated as shown by the arrows. On rocking to the left, the tip of the beak 6 engaging the alveolar process acts as a fulcrum and the beak 9 raises the tooth slightly. On rocking to the right, the beak 9 still engaging the tooth, rises in recess 14 relatively to the beak 7, the tip of which now becomes a fulcrum while the beak 8 raises the tooth. The extraction is repeated by continuing the oscillation. The diverging angle of the recesses 14 moreover converts the pressure applied to close the forceps into a force tending to raise the inner beaks, thus assisting extraction. In another modification, Figs. 13 and 15, the process-engaging beak 61 is slidably mounted in an aperture 65 extending obliquely through the tooth-carrying beak 57a and its head 67 slides along an undercut groove 68 in the forceps arm 53, said groove being at right angles to the aperture 65. An adaptation of the first modification to laterally applied forceps for lower anteriors is also described.
