Abstract: 888,310. Coiling; drafting; false twisting. HOWA KOGYO KABUSHIKI KAISHA. May 9, 1958 [June 11, 1957], No. 14918/58. Classes 120(2) and 120(3) A coiler comprises a rotatable coiler head 3 and a pair of coacting endless belts 11, 12 each passing around one of a pair of tension rollers 13, 13a. The coiler head is driven from a driving shaft 1. A gear 14 on a fixed annulus surrounding the head rotates a unit which comprises pincer gear 6 and bevel gear 7 and is mounted in the coiler head to rotate the driving rollers 10, 10a. Two calendar rollers 18, 18a may be arranged just below the coiler rid 15 through which the sliver enters the coiler so that the sliver is given a false twist between these rollers and the driving rollers 10, 10a which rotate with the coiler head. The twisted sliver may be drafted by choosing a driving gear train between the calender rollers 18, 18a and the driving shaft 1 to give these rollers a lower surface velocity than the driving rollers.
Patent GB-373406-A (GB)
Title: Improvements relating to the production of staple fibres from continuous filaments or threads
IPC: D01G1/04
Filed: 1931-05-21
Abstract: 373,406. Producing staple fibre from continuous filaments or threads. BRITISH CELANESE, Ltd., 22, Hanover Square, London. May 21, 1931, No. 15008. Convention date, May 21, 1930. [Class 120 (iii).] Staple fibre is produced from continuous filaments or threads by stretching the filaments and cutting them directly, say within onetenth to one-fifth of a second, after stretching. The method is particularly suitable for the production of staple fibre from filaments of organic derivatives of cellulose, such as organic esters of cellulose and cellulose ethers continuously with their production. When treating filaments of the reconstituted cellulose type such as viscose, nitrocellulose or cuprammonium, it is preferred to defer the operation until they have been subjected to the usual washing, bleaching, desulphurizing, denitrating or similar treatment. The stretching may be carried out within the elastic limit so that the fibres return to substantially their original length, or beyond the elastic limit so that they are still stretched after contraction. In forming staple fibre from filaments of cellulose acetate continuously with their production by the dry or evaporative method, three or more bundles are drawn from the spinning-machine, passed over a moistening wick, around a feed roller or guide and a stretching roller rotating at a peripheral speed approximately 20 per cent higher than that of the feed roller to a cutting-machine, such as described in Specifications 317,025 or 317,026, [both in Class 120 (iii), Yarns &c.], and are severed into fibres of, say, 1¢" length. The stretching may be imparted in more than one stage. The filaments may proceed from wound packages and may have been twisted prior to stretching, but it is preferred to employ untwisted filaments so as to facilitate the subsequent spinning. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the winding of filaments in the stretched condition on a drum, or winding upon a drum which is expansible for the purpose of stretching, and then severing them, the drum being slotted for the reception of cutting-means, means being provided to clamp the filaments to maintain them stretched. This subject-matter does not appear in the Specification as accepted.

Filed: 1953-05-29
Abstract: 771,994. Centrifugal governors. AMERICAN BOSCH ARMA CORPORATION, [formerly AMERICAN BOSCH CORPORATION]. May 29, 1953 [June 19, 1952], No. 15047/53. Class 57. [Also in Group XXVIII] A governing device for fuel injection apparatus (see Group XXVIII) comprises a shaft 14, centrifugal means 56 operatively connected to the shaft, a member 58 adapted to be actuated by the centrifugal means, and a pivotable lever 60 adapted to pivot about two pivot points 62, 77, the pivot point employed being determined by the position of the member 58. The lever 60 is connected by a rod 52 to a sleeve 48 controlling either the start or the end of the injection period and by a rod 65 to an adjustable link 67 pivotally mounted on the fuel control rod 69 and loaded by a spring 72. During idle running, the lever 60 pivots at the right-hand end of an elongated slot 61 on the pivot point 62 while on full load the lever 60 just contacts the pivot point 77 unless the engine speed drops below the governed speed when the lever swings about the latter pivot point with the left-hand end of the slot 61 approaching the pivot point 62 to move the fuel control rod and provide increased torque. The increase of fuel supplied may be adjusted by slackening a screw 76 and raising or lowering the pivot point 77 while the speed drop necessary to produce the increase of fuel may be varied by altering the effective length of the link 67. In an alternative construction, the pivot point 77 is adjustably mounted on the lever 60 which is connected by a pin and slot to a sleeve bearing against pivoted centrifugal weights. Specification 771,995, [Group XXVIII], is referred to.

Title: Improvements in and relating to nickel-iron and nickel-cadmium electric batteries
IPC: H01M4/02
Filed: 1945-11-30
Abstract: 593,643. Accumulators. MILNES, H. R., and MILNES ELECTRICAL ENGINEERING CO. (BINGLEY), Ltd. June 18, 1945, Nos. 15390, 15391 and 32459. [Class 53] Each of the electrodes in an alkaline accumulator comprises two metal sheets which are perforated and formed with grooves or other depressions, the two sheets being arranged back-to-back with the active material on the outer faces and the grooves forming channels between the sheets through which gas can escape. The positive electrodes may be of nickel or nickel-plated steel with active material consisting of nickel hydrate with or without graphite, the negative electrodes being of iron or steel carrying finely-divided iron with or without finely-divided cadmium or oxide of cadmium. The separating sheets may consist of woven glass, nylon or mercerized cotton or of porous rubber &c., the porosity of which is reduced by filling the interstices with an inert substance such as barium sulphate, calcium sulphate, magnesium oxide or aluminium silicate. The edges of the separators are rendered impervious by a filling of pitch, rubber solution, paraffin wax, &c. The electrodes and separators are pressed together in the container by springs or rubber. Electrodes of each polarity are held together and electrically connected by threaded rods which pass through apertures in the electrodes and separators. Fig. 5 shows a part of an electrode comprising a perforated metal plate having grooves formed by ribs 13, 14, 15 and provided with large and small openings 16, 18 to receive the rods 27 shown in Fig. 1. Two plates are pasted with active material 22, 23 and placed back-toback to form an electrode as shown in Fig. 4. The electrodes and separators are assembled to form the completed cell by first arranging in a jig a number of smooth rods corresponding to the rods 27 and threading on the rods an insulated steel plate 20 and a single positive plate 1 and a separator 3. Pairs of negative and positive plates 2, 1 with intervening separators are then stacked on the lowest separator 3. Springs 26 between two top insulated plates 24, 25 subject the stack to compression. The extensions 41, Fig. 5, of plates of like polarity are then connected together and to a source of current and the cell charged in an acid bath. When charging is complete, the rods on which the stack is assembled are removed and replaced by the threaded rods 27 which are of slightly greater diameter than the small holes 18 but smaller than the holes 16. The plates of like polarity thus make contact with one set of rods which are connected together above the plate 25 by a bus-bar, additional pressure being applied to the stack if necessary by nuts 29, 30. The extensions 41 are now cut off and the stack introduced into a casing which is closed and provided with terminals connected to the busbars.
