Title: Stud driver and extractor
IPC: B25B23/10
Filed: 1943-07-15
Abstract: 564,529. Stud boxes. AIRCRAFT SCREW PRODUCTS CO., Inc. July 15, 1943, No. 11564. Convention date, Aug. 13, 1942. [Class 83 (iii)] A stud box comprises a stud-engaging member 22 split at 33 for bevel closing at 28 by relative axial movement of a chuck body 21 having a polygonal engagement at 29 with the upper end of the member 22 which abuts the lower end of the box 1 which has projections engaging recesses in the body 21. The box 1 is provided with a screw thread, in the embodiment shown, in the form of a helical wire insert, to receive a threaded rod 10 the end of which bears through an interposed plug 34 on the top of the stud. A nut 35 is retained on a shoulder 4 on the box 1 and is threaded to engage the chuck body 21. The box 1 is polygonal at 2 and engages a polygonal part 15 of a sleeve 14 bored at its upper end to a diameter that will receive the polygonal part 2 with clearance. A spring confined between the parts 35 and 14 maintains the latter in engagement with a handled cross-bar 12 in the upper part of the bar 10 by which the device is rotated. By depressing the sleeve 14 until the polygonal parts 15 and 2 disengage and then giving it a part rotation return of the sleeve is prevented and one or more lugs 18 on the sleeve are free of the cross-bar. The bar is then rotated to adjust the position of the lug 34 according to the length of the stud and the sleeve 14 is then released in such a position that the lugs 18 are just behind the cross-bar in the direction of screwing up. Resistance to screwing in the stud will then cause relative movement between the parts to tighten the chuck within the limits permitted by the engagement of the cross-bar. with the other side of the lugs 18. The rod 10 is threaded the same hand as the stud but the nut 35 has a thread of opposite hand in order that the chuck may be further tightened by this means when necessary to remove a tight stud. In a modification the flange 3 on the box 1 is threaded to receive the nut 35 which then has an internal flange at its lower side to take below a flange on the chuck body and in this case all the threads are of the same hand as'that of the stud.

Abstract: 1,043,402. Treating woollen fabrics; textile treating apparatus. STEVENS & CO. Inc. J. P. March 25, 1963 [March 26, 1962; March 13, 1963], No. 11675/63. Headings D1L and D1P. A woven woollen fabric which may be stretched by an additional 6% in one direction and will return to its original state when the stretching force is released, is produced by wetting a woven fabric in which at least either of the sets of warp and weft yarns consist at least in part of wool fibres with a relaxing agent which is an agent capable of rupturing the disulphide bonds in the wool molecule, applying tension to one of the sets of yarns to permit the other set of yarns containing the wool fibres to move relative thereto and subjecting the fabric while in a smooth state in the presence of the relaxing agent to a temperature sufficient to increase the crimp frequency of the yarns containing the wool fibres by at least 6% and impart a permanent set thereto. The fabric treated may comprise wool fibres alone or in admixture with polyester, polyamide, acrylic, viscose rayon or cotton fibres and may be composed of yarns having a worsted twist factor of 1.5-4. Suitable relaxing agents are solutions of alkali metal, ammonium or organic amine sulphites, bisulphites, sulphoxylates and hydrosulphites, mercapto acids, mercapto alcohols, alkali metal borohydrides and alkali metal stannites. After impregnation with the relaxing agent the fabric may be squeezed until it has a liquid content of 50-130% by weight, subjected to a warpwise tension of 5-100 Ibs, heated by steaming at 210‹-225‹F. for 1/2-4 minutes and cooled by means of cold water or cool air. The fabric may subsequently be fixed by treatment with a dilute solution of formic or acetic acid, an alkali metal carbonate, hydrogen peroxide, sodium persulphate, water soluble zinc salts or alkaline dihalides. As shown in Figs. 1 and 1A the fabric 10 may be impregnated with a solution of the relaxing agent in tanks 15 and 19, passed between a pair of squeeze rolls 22 and 23 of which the upper roll 22 is loaded to leave a pick up of 50-130% of the fabric weight, passed over guide roll 26, under control roll 25 which actuates a control box 28 which is connected to the drive of rolls 22 and 23, over guide roll 26 and under guide roll 27 into autoclave 31 supplied with steam from supply pipe 37 through headers 38, through a vestibule 33 having a seal 34 to minimize the escape of steam. The rolls 35 and 36 in the autoclave are driven at a predetermined rate by a suitable adjustable variable speed drive mechanism (not shown). The fabric passes from the autoclave through exit vestibule 39 having a seal 40, passed around guide roll 41, under control roll 42, over guide roll 43, is cooled by cold water from spray header 49, scoured in scouring unit 60, passed through a series of unit 60A, 60B and 60C, 60A containing fixing agent, 60B containing desizing agent and 60C containing water for rinsing and further rinsed in tank 66 by spraying from spray header 67. 15 may then be folded by folder 70 and dried.

Title: Improvements in variable resistances
Inventor: OLAH GEORGE
IPC: H01F21/00
Filed: 1949-05-03
Abstract: 668,185. Variable resistances. PRECISION DEVELOPMENTS CO., Ltd. May 3, 1950 [May 3, 1949], No. 11832/49. Class 37. A variable resistance has a helically-wound resistance winding and a plurality of electrically bonded contact elements, non-rotatable about the axis of the winding, slidable axially of the winding, rigidly connected together, and spaced around the axis of the winding so that their points of contact therewith lie in a plane normal to the axis. Fig. 1 is an end view, partly in section, and Fig. 2 is a view in the direction of the arrow II. A resistance winding 1 is wound helically upon a straight fixed former 2, parallel to which is fixed a straight contact-bar 3. Below these is a guide 4 of rectangular section having a triangular groove 6 on its lower face. An arm 8 is pivoted at 9 to a depending portion 10 of a carriage 11 which is supported on the top surface of the guide 4 by wheels 16, 18. The arm 8 carries a rotatable wheel 7 engaging one flank of the groove 6 and held in engagement therewith by a spring 17. Two wheels 13 mounted on bushes 12 on the carriage 11  engage one side of the guide 4, with which they are held in engagement by the engagement of the wheel 7 and the flank of the groove 6. An insulating terminal block 20 is mounted on an insulating plate 21 secured to the top of the carriage 11. The top of the block 20 is covered by a U-shaped metal band 22. A U-shaped insulating contact holder 23 carries on its inner surface a metal band 24 which makes contact with the band 22, the holder 23 being rigidly secured to the block 20. A contact strip 25a is formed integral with the band 22 and projects therefrom parallel to the axis of the former 2, a dimple 26a being formed near the free end and contacting with the winding 1 on the former 2. Three similar contact strips, of which two only 25b, 25c are shown, are formed integral with the metal band 24 and have corresponding dimples 26b, 26c, the points of contact of all the dimples with the winding lying in a plane normal to its axis. The four contact strips, which are electrically bonded by means of the bands 22, 24, are connected to the contact bar 3 by a contact strip 27. Owing to the wire 1 being helically wound, only one dimple engages the winding. When the carriage 11 has been moved through one quarter the pitch of the winding this dimple breaks'contact and a second dimple makes contact at a point on the winding displaced by 90 degrees, so that a change of resistance equal to one quarter the resistance of one turn can be obtained. The former 2 may alternatively be of square section. The resistance may be used as a potential divider.

Patent GB-384309-A (GB)
Title: Process for the production of large crystalled metallic bodies
IPC: C22C1/04
Filed: 1931-04-22
Abstract: Large crystalled bodies, such as blocks, bars, sheets, bands, wires and single and multiple spiralled incandescent bodies, of refractory metals such as tungsten, rhenium, and molybdenum are produced by incorporating additive materials with the starting materials, and heating first to the sintering temperature and then to the crystallization temperature, the additive materials being such as will not volatilize at this latter temperature but develop a vapour pressure in the metal bodies, setting up internal stresses.  The crystallization temperature is of the order of 1000-1200 DEG  C. above the sintering temperature, which for tungsten is about 1500 DEG C.  Additive materials referred to are zirconium and thorium phosphates, iron, aluminium, thorium, magnesium and zirconium silicates, calcium titanate, aluminium borate, calcium and barium fluorides, zirconium oxyfluoride, iron-aluminium silicate, magnesium-aluminium silicate, calcium - titanium silicate, iron-magnesium borate, calcium fluophosphate or mixtures thereof. Quantities varying from ,01-,30 per cent are specified.  The additive materials or their components may be admixed with the reduced metal powder or with the raw materials e.g. tungstic acid, from which the metal is produced.  In the production of wires and incandescent spirals, the metal blocks may only be incompletely sintered, complete sintering and crystallization being effected on the wires.  In an example, a thin paste of tungstic acid hydrate is admixed with solutions of sodium or ammonium fluoride and barium chloride.  The paste is dried at 300 DEG  C. and reduced in hydrogen at 820 DEG  C. The metallic powder is moulded and heated in hydrogen at 1100 DEG C., and then in hydrogen by a high-amperage low-voltage alternating current to a temperature above the sintering temperature. Specification 121,596, [Class 39 (ii), Electric lamps, Incandescent], is referred to.

Abstract: 312,054. Corning Glass Works, (Assignees of Smith, R. D.). May 19, 1928, [Convention date]. Etching. - In the preparation of an etching slurry or solution for frosting lamp bulbs and other glass articles, certain of the ingredients are fused prior to being ground and incorporated with the other ingredients so that a thinner slurry for a given strength is produced allowing of more economical use. In preparing an etching solution containing sodium fluoride and soda ash, these materials are separately fused and ground and then mixed with suitable proportions of ammonium carbonate, hydrofluoric acid, ammonium bi-fluoride, and water. The resulting mixtures are then mixed together to form the etching solution. Instead of fusing the whole of the sodium fluoride and soda ash, a part only of one or both may be fused, the remainder being ground in the infused state. Potassium fluoride may be used instead of sodium fluoride.
