Title: An improved method for the preparation of cellulose, particularly for nitration
IPC: D21B1/00
Filed: 1928-06-16
Abstract: 322,997. Heide, H. C., (Schaub, J. J.). June 16, 1928. Pulp, preparation of.-Wood cellulose is subjected to long continued disintegration, for example for 2-3 hours, in water by means of a refining mill or hollander and the resulting slime or pulp freed from water on a paper-making machine in which sheets, ribbons or strips are formed. The ribbons or strips may be twisted into a cord and cut into small pellets, which are particularly suitable for nitration. Small quantities of acids, alkalies or salts may be added to the water. In order to ascertain the proper period for the disintegration process, a sample of the cellulose, which must be sufficiently finely ground to settle evenly, is placed in the hollander and this is started up to produce an equally distributed pulp. A hundred cubic centimetres of this pulpy liquid are then taken out and the operation of the hollander stopped. The hundred cubic centimetres of pulpy liquid are placed in a glass cylinder which is filled with water to the five litre mark or according to the Provisional Specification to the litre mark. The cylinder is shaken and the contents allowed to stand for two hours, when the volume of the settled is measured. The hollander is then re-started and at intervals its operation is stopped and similar samples treated in the same way. When a sample is obtained of which the final volume is one-half of that in the case of the first sample taken before treatment the optimum state is reached. The total time for which the hollander has been in operation is then noted and the bulk is subjected to treatment for this time.

Title: Improvements in harness for aeronauts
IPC: B64D25/06
Filed: 1929-06-07
Abstract: 334,598. Bristol Aeroplane Co., Ltd., and Frise, L. G. June 7, 1929. Body harness. - Means for anchoring an aviator's harness 10 to an aircraft comprises a cable 12 attached at one end to the harness, a resilient member 15 connecting the other end of the cable to the aircraft, a rotatable drum 21 round which the cable passes in such manner as to be rotated when the cable is moved axially, locking means co-operating with the drum to lock it against rotation and means for releasing the locking means at will. The drum is formed with a circle of holes 29 co-operating with a looking pin 30 normally pressed to locking position by a spring 34, but retracted when desired by a Bowden wire 35. The cable is passed twice round the drum, and prevented slipping thereon by a loop round the axis of the drum half a turn from one end. Check cables 36, 37 connect the harness and drum support and this and the resilient member 15, respectively. The member 15 is, preferably, an elastic cord, e.g., of rubber, but may be a tension spring. Normally, the cable 12 is fully wound on the drum. If the aviator requires increased freedom of movement, he retracts the pin 30 and exerts a pull on the harness the cable then unwinding an amount desired up to 1¢ turns. The desired degree of freedom can then be maintained by releasing the pin 30 to engage one of the holes 29. When the additional freedom is no longer required, the locking pin is disengaged when the tension member 15 rewinds the cable on the drum. A pawl and ratchet wheel may be substituted for the parts 29, 30.

Title: Improvements in or relating to torque transmitting devices
IPC: F16D43/21
Filed: 1944-09-14
Abstract: 594,536. Shaft couplings. WOLFF, O. E. Sept. 14, 1944, No, 17605. Convention date, Feb. 25. [Class 80(ii)] Torque is transmitted between members 22, 24, by friction between a surface 28 on the member 22 and a plurality of friction shoes 30 carried by the member 24 and urged into engagement by yielding material 36, such as rubber. The interior of the coupling contains lubricant. If the members 22, 24, are rotating at equal speeds there is dry friction between the surface 28 and shoes 30. Should the speeds vary, by overloading, for example, oil becomes wedged between the friction surfaces and the coupling action ceases. To re-couple the members their speeds must first be equalised. As shown, the shoes 30 have lubricant passages 48 and are carried with play in a cage 32 rigid with the member 24. A nut 40 and spring washer 42 carried by an adjusting screw 38 provide for axial compression of the yielding material 36 to vary the radial pressure between the friction surfaces. In a modification the cage 32 is omitted, the shoes being moulded in a rubber mass secured to the member 24. Axial compression of the rubber is effected through adjustable spring pressure. Each shoe may be in two parts, one part being. engaged by the yielding material and having a rounded projection on which the other part having the friction surface is universally supported. All constructions permit slight universal relative movements of the coupling members 22, 24.

Abstract: A brown-yellow lacquer comprises a nitrocellulose lacquer mixed with a brown solution obtained by reacting ethylene oxide with sublimed anhydrous ferric chloride in alcohol.  A brown-yellow solution yielding golden-yellow, transparent films and threads comprises a solution of acetyl cellulose in a suitable solvent mixed with a brown solution obtained by reacting ammonia with sublimed ferric chloride dissolved in alcohol and then treating with ethylene oxide.  Lacquers comprising this last brown solution may be prepared by adding to the solution a solution of an alkyd resin obtained from phthalic acid, glycerine and linseed oil fatty acid; these lacquers may be baked. Mouldings with a transparent yellow-brown coloration may be obtained from polystyrene mixed with a brown compound obtained by reacting ethylene oxide with anhydrous ferric chloride in the presence of lauric acid.  Specification 695,421, [Group IV (b)], is referred to.ALSO:Iron alcoholates may be prepared by reacting an anhydrous iron halide with an alkylene oxide, by reacting an alkali ethylate with sublimed iron chloride or by reacting alkylene oxides with ferric salts in the presence of stabilizers such as fatty acids or natural and synthetic resins.  The method described in Specification 695,421 also is referred to.  In examples: (1) ethylene oxide (150 parts) is passed into a solution of anhydrous ferric chloride (100 parts) in absolute alcohol and the product then concentrated; (2) ferric chloride in alcohol is treated with insufficient ammonia for complete neutralization and then reacted with ethylene oxide; (3) ethylene oxide (110 parts) is reacted with ferric chloride (81 parts) in benzene containing lauric acid (100 parts).ALSO:In a process for producing brown-yellow coloured organic materials, a substituted or unsubstituted iron alcoholate is incorporated in the material to be coloured.  The iron alcoholates may be prepared by reacting ammonia with a solution of an iron halide in an alcohol (as described in Specification 695,421), by reacting alkali ethylate with sublimed iron chloride, by reacting alkylene oxides with iron halides, or by reacting alkylene oxides with ferric salts in the presence of stabilizing agents such as fatty acids, natural or synthetic resins. An iron alcoholate may be dissolved in the anhydrous solution or melt of a lacquer, plastic or spinning solution, which may be worked up as usual.  The iron alcoholate may then be hydrolyzed, in most cases by atmospheric humidity, to form a yellow-brown transparent pigment of ferric hydroxide.  A wood stain comprises a solution in alcohol of a brown solution obtained by reacting ethylene oxide with sublimed anhydrous ferric chloride in alcohol.

Abstract: 890,980. Embossing surfaces. HICKS, A. A. May 20, 1960, No. 17887/60. Class 100(2) In a method for making a die for producing an impression having a three-dimensional appearance on a flat surface a number of wire-like elements are bound into a bundle, one end of the bundle is shaped into the desired three-dimensional pattern, the binding of the bundle is loosened and the shaped ends of the elements are brought into coplanar relation while preventing relative rotation thereof. As shown a bundle 10, Fig. 2, of wires 11, preferably of square crosssection, is held together by a band 12 whilst one end of the bundle is shaped, e.g. by carving, into a pattern 13 to represent the object it is desired to duplicate on a flat surface. The shaped ends of all the wires 11 are then brought into coplanar relation and, if desired, the uncarved ends of the die are cut so as to form a suitable flat support surface for the back of the die. By virtue of the shaping of the ends of the wires, the end of the bundle now presents a substantially flat representation 13<SP>1</SP>, Fig. 4, having the optical appearance of the pattern 13.

Title: Improvements relating to excavating machines
IPC: E02F9/02
Filed: 1961-05-17
Abstract: 945,400. Endless-track vehicles. S.r.1. SCOMA & C. May 17, 1961 [May 17, 1960], No. 17982/61. Heading B7H. [Also in Division E1] An excavating machine has two endless tracks 1 between which is mounted a substantially L-shaped frame 35 and a scoop 5 movable over the frame, and at all times within parallel planes extending from the outer edges of the tracks, from a digging position to a discharge position. The vehicle has a superstructure 2 on which are mounted, by means of supports 3, arms 4 connected at their ends to the scoop 5. Attached to a transverse shaft 6, which is rigidly attached to arms 4, is one end of a chain 7, whose other end is attached to a winch 8 which is driven by the motor 9 through gear-wheels 10 to 14 mounted in a casing 81. Two shock absorbers 15 are provided to limit the movement of arms 4 when the scoop is raised to the position shown, in Fig. 1, in dotted lines. Disposed at the rear end of the superstructure 2 is a bin 16 which pivots about bearing 17 connected by supports 18 to the superstructure. Ribs 19 which connect bearing 17 to bin 16 are pivotally connected at 20a to two rams 20 whose other ends are pivotally attached to lugs 21 on the vehicle frame. The rear cover 22 of bin 16 is pivotally mounted at 25 and is controlled by a lever 22a articulated to lever 23 which is pivoted at 24 to the structure 2. The arrangement is such that the scoop 5 is raised and deposits the material therein into bin 16 which is then rotated about bearing 17 to the position shown in dotted lines, during which motion, cover 22 is opened under the action of levers 22a, 23. At this point the bin will discharge its contents into a truck 27. Two compressed-air motors 36, 37 mounted on the L-shaped frame 35 are used to drive the endless tracks. Motor 36 drives the right-hand track through pinion 38a and gear-wheels 40, 43, 44, 46, 48, 51, 54, 55, 58 while motor 37 drives the left-hand track through pinion 61 and gear-wheels 63, 64, 65, 66, 69, 70, 73. In a modification, Figs. 5 and 6 (not shown), a bin is not provided, but the scoop is so mounted that when it is being raised it also travels to the rear of the structure from which position its contents may be deposited immediately into the truck.

Title: Non-woven fabrics
IPC: D04H1/46
Filed: 1974-04-26
Abstract: 1474101 Embossing IMPERIAL CHEMICAL INDUSTRIES Ltd 11 April 1975 [26 April 1974 1 Nov 1974] 18326/74 and 47356/74 Heading B6J [Also in Division D1] A method of producing a spot bonded non- woven fabric by compressing a web between two members whose co-operating surfaces each have different surface land patterns heated sufficiently to activate thermally bondable (fibrous) material in the web is characterized in that the lands are isolated projections opposed pairs of which, one or each member, differ from at least some other such pairs in their degree of relative register in two directions at right angles. As exemplified each member is a patterned roll. The two rolls have different types of pattern, or the spacing of the pattern on one roll is different from that on the second roll and/or one pattern is skewed with respect to the other. Skew angles of 3 and 15 degrees are exemplified. Preferably the rolls are accurately parallel and one or both patterns are skewed with respect to the axis of their roll, but for larger rolls it is possible to skew one roll with respect to the other. With a rectangular pattern skewing the pattern ensures that there are always some lands at the nip. Specified land patterns are a square array of square lands, a square pattern of rectangular lands skewed at 3 degrees, a pattern of echeloned dashes and an engraved pattern of intersecting broken lines. The web to be embossed may be corded or airlaid and may be needle punched before hot embossing. In Example 1 the fibres are of crimp 1 cm. nylon 66 core/nylon 6 sheath fibres with a core/sheath volume ratio of 1. The rolls were heated to 217 C. In Example 2 the fibres were 6 crimp/cm. polyethylene terephthalate core (67%)/ethylene/isophthalate-ethylene terephthalate sheath (33%). Other fibres are (3) nylon 6 monocomponent, (4) nylon 6 mixed with nylon 66, (5) wool mixed with the sheath/ core fibres of Example 1 and (6) nylon 66 mixed with the fibres of Example 1. The fibres may have up to 15À4 crimps/cm. although non- crimped fibres give a stronger product. Dressing the fibres with 0À1% silica and a fatty alcohol/ ethylene oxide condensate before web formation also increases the fabric strength.

Title: Improvements in apparatus for the automatic tuning of electric circuits
IPC: H03J7/30
Filed: 1945-07-18
Abstract: 612,316. Automatic tuning control systems. GENERAL ELECTRIC CO., Ltd., and FAIRBAIRN, E. P. July 18, 1945, No. 18431. [Class 38 (iv)] [Also in Group XL (c)] In an automatic tuning device a motor or like means drives the circuit through resonance, causing the direction of drive to be reversed, the motor finally being stopped by means controlled by the rate of change of response. The Figure shows a circuit L, C to which a signal is fed via coil D. Variable condenser C is normally biassed by a spring to a rest position at one end of its travel and is controlled by motor TM through a main clutch M and either a fast forward clutch F or a slow reverse clutch R. In this position cam-operated contact CON is made, so that if the switch ST is depressed, relay S operates, connecting power to the motor and clutches, through contact S2. The condenser thus starts rotating, relay S being held by contact S1 when contact CON breaks, and in the absence of a signal continues to the end of its range at which point contact CON breaks, causing clutch M to release, thus allowing the spring to return the condenser to its rest position from which it again starts moving forward. If a signal is applied to circuit LC, a current flows in the grid circuit of valve V1  which at resonance is sufficient to operate relay A. Contact A1 of this relay causes the reverse clutch to be brought into operation and since the motor overruns the resonance position, the reverse movement slowly restores resonance. Contact A4 has meanwhile provided a holding circuit for relay A and contacts A5 and A2 have removed the short circuit from transformer T and relay B respectively. The change in grid current as resonance is approached induces a voltage in the secondary of transformer T which causes relay B to operate and thus to operate relay E. At resonance the rate of change of grid current reduces to zero and relay B therefore releases. Contact B1 breaks the circuit to the motor and contact B2 completes the short-circuit of relay B. Should the applied signal be removed, relay A releases, breaking the circuit for relay S at A3. Contact S2 would, therefore, break, releasing clutch M and thus allowing condenser C to return to its rest position when contact CON is remade, causing the motor to restart. A diode or crystal rectifier may be used instead of valve V1 and further contacts may be provided on relays B or E to perform auxiliary functions such as connecting H.T. or switching from high to low power.
