Title: A method and an apparatus for the braking of yarns or threads, in particular for the manufacture of a cord, as well as the cord thus manufactured
IPC: B65H59/10
Filed: 1960-05-24
Abstract: 906,244. Yarn tensioning device. ONDERZOEKINGSINSTITUUT RESEARCH N.V. May 24, 1960 [May 25, 1959], No. 18315/60. Class 120 (2). In a thread or yarn brake which is suitable for a yarn doubling device and in which a braking roller 24 has fast on it a magnetic hysteresis disc 47 for co-operation with a crown magnet 41 coaxially arranged with its poles near to and facing the disc and a pressure roller 25 co-operating with the braking roller, the pressure roller is rotatably mounted on the free end of an arm 26 pivotally mounted on the magnet support or housing 21, the axis of rotation of the pressure roller being within the compass of the magnet. Yarn enters the device through the eyelet 8 and passes via a tubular guide 38 and a guiding funnel 36 to the braking roller 24 on which it is nipped by the pressure roller 25. The yarn then passes about the braking roller 24 through an angle which is preferably greater than 270 degrees before leaving the roller and passing via the guide pulley 39, out of the device. Provision is made for the adjustment of the distance between the hysteresis disc and the magnet poles and also for the adjustment of the spring force urging the arm 26 carrying the pressure roller 25 toward the braking roller. The pressure roller and/or the braking roller may be formed with a cylindrical centre portion and frusto-conical outwardly tapering outer portions, the apex angle of which is about 1 degree and the covers for the rollers may be made from a rubber-like modification of polyurethane. The space between the poles of the magnet is filled with a synthetic resin to prevent accumulation of dust.

Title: Improvements in or relating to integrating apparatus for ships' logs
IPC: G01P5/00
Filed: 1928-06-25
Abstract: 310,231. Wahlstrom, G. A. June 25, 1928. Integrating. - In integrating-apparatus for ships' logs wherein an electric circuit to a counter is closed at each reciprocation of a member, the time and extent of this reciprocation varying with the speed of the vessel, the member carries a pair of contacts located in the circuit and adapted to be closed by engagement with the speedadjusted means. An arm 5 pivoted at 3 and drawn upwardly by a spring 6 takes up a position corresponding with the speed, a roller 2 bearing for this purpose on a cam 1 rigid with the speed pointer 25. A lever 10 also pivoted at 3 may be drawn downwardly against the action of a spring 7 by means of an electromagnet 9 the armature 8 of which is fixed to the arm. When the circuit to the magnet is broken the arm rises at a uniform rate controlled by a clockwork 27. The counter is in parallel with the magnet and the circuit is opened and closed by means of a pair of contacts 11, 12 mounted on the lever 10. The contact 12 is carried by a pivoted dog 22 and as the lever ascends a catchpiece 15 mounted on it comes eventually against a lug 4 of the arm 5 and is thus caused to free the dog 22 which thereupon rocks counter-clockwise to close the circuit. The lever 10 being then immediately drawn downwards by the magnet, the dog 22 meets a fixed stop 23 and is consequently rocked to open the circuit, and is again held by the catch-piece 15 during the ascent of the lever 10.

Abstract: 507,617. Valve gear. AUTO UNION AKT.-GES. June 21, 1938, No. 18489. Convention date, June 21, 1937. [Class 7 (vi)] Fuel-injection valves are actuated by magnetostric tive forces occasioned by the variations in length of a bar of alloy when subjected to an electric field. The Figure shows such a bar 1 arranged coaxially within an electromagnetic coil 2 and between the ends of a U - shaped member 5 connected at 11 to the valve 6. The two arms of the member 5 are formed with fulcra 7 bearing on the casing 3 and arranged to divide the arms into short and long portions 9, 10 respectively, so that elongations of the bar 1 are magnified so as to produce a deformation of the cross-piece 11 of the member 5 as indicated in dotted lines, thus opening the valve. The valve is closed by fuel pressure when the bar 1 returns to its original length as the current supply to the coil 2 is cut off. The bar 1 may be of an alloy containing 20 per cent nickel and 80 per cent iron.. It may also consist of several layers of different alloys, so as to bend as well as expand

Title: Bright silver plating
IPC: C25D3/46
Filed: 1951-08-07
Abstract: A brightening agent for addition to cyanide baths for the electrodeposition of silver consists of a reaction product of ketones of the general type RCH2.COCH3, where R stands for hydrogen, alkyl, acetonyl or carboxymethyl with carbon disulphide; the reaction product is prepared in presence of alkali metal hydroxide and is finally freed from alkali and hydrogen sulphide.  Formaldehyde may be reacted with the ketones along with the carbon disulphide.  The preferred ketones are acetonyl acetone, methyl ethyl ketone and acetone.  Example 1 : 0.2 mols. acetonylacetone, 0.8 mols. carbon disulphide and 1.2 mols. aqueous sodium hydroxide (50 per cent) are put into a closed vessel supplied with a reflux condenser.  On occasional shaking, the two-phase reaction mixture darkens, a moderate heat evolution occurs and after about 45 minutes the mixture is homogeneous, dark-red-brown and fairly warm.  It is then cooled to room temperature and diluted with 400 ml. of water, 1.2 mols. of hydrochloric acid (1 : 1 by volume) are then slowly added under stirring.  An almost black resinous mass is precipitated and much hydrogen sulphide escapes.  The precipitate is powdered, washed with water and re-dissolved with 400 ml. of aqueous sodium hydroxide. This solution is then diluted to 500 ml. and 0.8 mols. of hydrochloric acid (1 : 1 by volume) added under stirring.  The dark brown precipitate is filtered off, washed with water, and air or vacuum dried.  Example 2: The product from the initial stage of example 1 is diluted to 600 ml. and instead of hydrochloric acid, slightly over 1.2 mols. of acetic acid are added.  The solution is boiled down to 400 ml., neutralized with potassium hydroxide solution, diluted to 600 ml. and filtered.  The dark red solution is employed as the plating bath addition.  Example 3: The product from the initial stage of example 1 after the mixture has become homogeneous is cooled to room temperature and 0.1 mol (7.5 ml.) of aqueous formaldehyde (37 per cent) is added.  An exothermic reaction occurs and after about 15 minutes the reaction mass is cooled, diluted and precipitated with hydrochloric acid.  The precipitate in the form of a hard resinous lump is washed with water.  After standing overnight it is powdered, dissolved in aqueous, precipitated with dilute hydrochloric acid, filtered, washed, redissolved in aqueous sodium hydroxide and reprecipitated with hydrochloric acid and dried to form a light brown powder.  Further examples describe the preparation of products by reaction of methyl ethyl ketone with carbon disulphide and formaldehyde and by reaction of methyl ethyl ketone with carbon disulphide in the presence of dimethoxytetraglycol (CH3OCH2CH2OCH2CH2)2O.

Title: Improvements in or relating to the production of carbon fibres
IPC: D01F9/22
Filed: 1970-04-17
Abstract: 1,264,763. Polyacrylonitrile fibres. SIGRI ELEKTROGRAPHIT G.m.b.H. 17 April, 1970 [7 April, 1970], No. 18579/70. Heading B5B. [Also in Division C1] Non-cellulosic synthetic polymer fibres, preferably of polyacrylonitrile or a copolymer of polyacrylonitrile and methylmethacrylate, are rendered more suitable for carbonization by a process in which they are (1) contacted at a temperature of from 180-230‹ C. with a liquid condensation agent which boils at a temperature higher than said temperature and comprises one or more halides of elements of Groups IVA or IVB of the periodic table, to effect cross-linking, and (2) oxidized in the presence of a dehydrogenating agent, preferably air, although chlorine and sulphur are also specified, at 175-350‹ C., while free of any substantial tension. Before treatment the fibres are advantageously subjected to stretching to a ratio of at least 4 : 1 and the tensile strength of the stretched fibres is at least 4 ponds/den. During stage (1) of the process fibres are preferably contacted at a temperature between 190‹ and 200‹ C. The condensation agents are preferably used in the form of complexes, with for example, amines, ethers, esters or dimethylformamide, and they may be used in solutions of high boiling solvents, the use of solvents being essential when low boiling tetrahalides of Group IV elements are used in the absence of complexing agents. Suitable solvents are ethers and esters, for example o-nitroanisole, di-n-butylterephthalate and iso-octadecylbenzoate, which may simultaneously act as complexing agents. Solutions of condensation agents used in the treatment may contain at least 0À8% by weight of the complex of the condensation agent and preferably contain from 1À0 to 1À5%. The rate of rise of temperature during stage (2) of the pre-carbonization treatment is suitably between 40‹ and 200‹ C. per hour, preferably the temperature rises at a rate of 100‹ C. per hour from 200‹ to 300‹ C. In examples fibres of a copolymer containing 95% acrylonitrile and 5% methylmethacrylate are stretched, treated with solutions of complexes of tin tetrachloride, tin tetrabromide, titanium tetrachloride or lead tetrachloride in one or other of the aforementioned solvents at temperatures between 190‹ and 200‹ C. for times between 30 and 60 minutes, washed with acetone and water and dried at about 120‹ C. The fibres were then subjected to an oxidation treatment in a tube furnace through which a stream of air was continuously passed and in which the rate of rise of temperature was 100‹ C. per hour in the range 200-300‹ C. The oxidized fibres were then carbonized and optionally graphitized (see Division C1).

Filed: 1972-04-21
Abstract: 1321038 Film cartridges POLAROID CORP 21 April 1972 [21 April 1971] 18641/72 Heading G2A A box-like cartridge for storing a stack of film units has a flat battery adjacent the bottom wall of the cartridge, the battery having a terminal which registers with an aperture in this wall so that a contact on the camera can make contact with the terminal when the battery is inserted therein, the aperture having a tapered configuration. As shown, the cartridge casing is formed as a box-like structure 12, one end wall 22 being initially open so that a pack of film units (not shown) may be inserted. The battery is an electro-chemical cell assembly 48 mounted on a stiff card 46, and has side-by-side positive and negative terminals on the underside. The card has openings 54, 56 in register with the terminals, to allow contact to be made from below. The bottom wall 16 of the cartridge casing also has two corresponding apertures 60, 62. When the cartridge is inserted into the film chamber of the camera, a leaf spring 74 secured to the inner surface of the rear wall 70 of the chamber urges the cartridge against the forward wall 69. A pair of leaf springs 76, 78, having the general shape of an inverted V, are each secured at one end to the rear wall 70, the other ends (as at 86) being free to slide on wall 70. At the apex of each spring is a contact element 88, 90. As the cartridge is inserted into the film chamber, its forward end engages and depresses the leaf springs. As it reaches the end of its travel the springs return to their undeflected state, the contact elements 88, 90 now passing through the apertures 60, 62 and 54, 56 to make firm contact with the battery terminals. The apertures 60, 62 taper, as shown, from a head portion 64 to a tip portion 66, and their edges may be bevelled. This tapered shape allows the contact 88, 90 to enter gradually through the apertures 60, 62 as the cartridge is inserted into the camera, so that a smooth and positive contact is made. A similar reverse action occurs as the cartridge is withdrawn.
