Abstract: 120,135. Heurtley, E. S. Dec. 6, 1917. Induction, preventing.-The disturbances produced by the action of a transmitter on one cable or land line upon the receiver of an adjacent cable or land line are eliminated or modified by employing resistances in the earth circuits and by connecting the unearthed sides of these resistances by a circuit containing a condenser, or a condenser and a resistance, or by connecting the unearthed side of one resistance to the cable or to the beginning of the artificial line of a duplex system. When applied to a duplex bridge system, a circuit containing capacity and resistance may be connected ! across the beginning of the artificial line and the earth plate of this line to maintain the balance of the system. The correction circuit may be applied to a second winding on the operating coil, or may be inductively coupled to the earth circuit of one of the lines or cables. In the arrangement shown in Fig. 1, a resistance 3 is connected between the earth-plate of the artificial line 5 and earth, and a resistance 4 between the earth-plate of the artificial line 5<1> and earth; while the two earth-plates are connected by a circuit containing a condenser 6. In the modification shown in Fig. 2, a circuit containing a capacity 6 and a resistance 7 is connected to the unearthed side of the resistance 4 and to a point 10 in the cable 1. To maintain the balance of the bridge, a condenser 8 and a resistance 9 are connected across the beginning of the artificial line and the earth-plate of this line. In the modification shown in Fig. 3, the resistance 4 is placed between the earthed pole of the transmitter 11 and earth, and the condenser 6 connected to the earth-plate of the artificial line 5 and to the unearthed side of the resistance 4. In a modification, the operating coil of the cable 1 is provided with an additional winding connected across the resistance 4, Fig. 1, and to the artificial line 5, and this circuit may contain a condenser. An additional winding on the coil of the cable 2 is similarly connected to the resistance 3, Fig. 1, and to the artificial line 5'. In a further modification, a winding is placed across the resistance 4, Fig. 1. and this winding is inductively coupled to a circuit connected across the unearthed side of the resistance 3, Fig. 1, and to the beginning of the artificial line, this circuit containing the transmitter of cable 1.

Title: Improvements in the production and treatment of artificial filaments, yarns, films and like materials containing cellulose derivatives
IPC: D01F2/28
Filed: 1933-06-27
Abstract: Artificial filaments, threads, yarns, ribbons, films, and like materials containing organic derivatives of cellulose are brought into a plastic condition by treating them uniformly along their length with a medium comprising an aliphatic compound containing halogen and oxygen, and they are subjected to a stretching or shrinking operation.  The halogen-oxygen compound may be contained in the coagulating bath when the materials are produced by a wet spinning process.  The materials may be treated continuously with their production by dry or wet spinning processes, or they may be treated in a separate operation.  Stretching may be restricted to the portion of the travelling materials which has been brought to a plastic state.  The filaments may be treated while arranged in warp formation.  The halogen-oxygen compound may contain more than one halogen or oxygen atom, and the oxygen is preferably present in a polar group such as a hydroxyl, ketonic, or ester group.  Chloral hydrate, chloral alcoholate, chloretone, dichloracetone, chlorine derivatives of ethyl acetate, ethylene chlorhydrin, glycerine mono- and di-chlorhydrins, are examples of halogen-oxygen compounds which are used.  Other solvents or softeners may be present e.g. acetic acid, acetone, the ethers, esters and ether-esters of olefine glycols, dioxane, methylene ethylene ether, ethyl lactate, diethyl tartrate, diacetone alcohol.  The solvent or softener may be employed in solution in water, alcohols, ethers, hydrocarbons, or chlorinated hydrocarbons.  The spinning solutions may contain the same solvent or softener as is used in the coagulation bath or subsequent treatment bath.  Cellulose acetate in a mixture of chloral hydrate and dioxane may be spun into an aqueous solution containing chloral hydrate and dioxane.  Specifications 277,089, 323,790, [both in Class 2 (ii)], 340,324, 340,436, 340,437, 378,858, and 405,275 are referred to.

Filed: 1970-04-17
Abstract: 1301184 Rotating member viscometer RION KK 17 April 1970 18555/70 Heading G1S A viscometer comprises a driving shaft 16 longitudinally movable arranged to be driven at a predetermined fixed speed of rotation, and to drive a spindle 30 disposed perpendicularly to the shaft, the spindle carrying an element 32 which is to be rotated in the liquid whose viscosity is to be determined and which will then experience a torque due to the viscous drag of the liquid, at least one resilient element 36 for exerting a resilient force lengthwise of the driving shaft, means for axially applying a thrust to the driving shaft in response to the torque provided by the end element to displace the driving shaft against the action of the resilient element 24, 28 and means for detecting the displacement of the driving shaft to provide a measure of viscosity 38, 40, 42, 46. As described rotating member 32 is driven in direction 64 from constant speed motor 12 through gears 14, 22, worm 24 and worm wheel 28. Torque in direction 68 resulting from viscous drag causes axially slidable shaft 16 to move in direction 70 against spring 36, the displacement of shaft 16 being translated through rack 38 and pinion 42 into movement of pointer 42 across a dial 46 graduated to read in viscosity units. Errors due to vibration of the pointer may be eliminated by applying the force of spring 36 to a pulley 56; Fig. 2 (not shown), on spindle 44 of the needle 42 so that the pinion 42 always engages one side of the teeth on rack 38. These errors may also be prevented by applying the force of spring 36 to pinion 40 through a second rack 90, Fig. 4 (not shown), on the opposite side of pinion 40.

Patent GB-1037484-A (GB)
Title: Elastic yarns and methods of preparing them
IPC: D02G1/02
Filed: 1963-05-10
Abstract: Yarn containing keratinous fibres is crimped by twisting the yarn, setting the twist by treatment with a reducing agent, and then untwisting at least some of the imposed twist.  Keratinous fibres mentioned are various animal wools and they may be blended with non-keratinous fibres, for example cotton, rayon, cellulose acetate and triacetate, vinyl, acrylic, polyamide and polyester fibres, to produce a single or multi-ply yarn to be crimped.  The imposed twist may be in the same direction as, or in the opposite direction to, the original twist in the yarn while the back twist may be greater or less than the imposed twist.  In an example the yarn is twisted and wound on to a perforated dye spindle which is immersed in an aqueous solution containing 1% sodium bisulphite. After ten minutes excess reducing agent is drained from the yarn and the yarn is then steamed for a further ten minutes.  The yarn is then rinsed, optionally dyed, dried in an oven at 80 DEG C, and then entwisted on to another bobbin.  If the yarn has been stretched on a bobbin for an extended time it has little tendency to retract unless exposed to steaming or wetting.  The retracted yarn has either a helical or random configuration depending on the degree of twist in the set state.  The yarn may be plied with a similar elastic yarn or with a non-elastic yarn comprising keratinous and/or non-keratinous fibres.  Reducing agents listed include lower alkanolamine sulphites; metallic formaldehyde sulphoxylates; alkali metal sulphoxylates, borohydrides, and sulphites; sodium sulphide, hydrosulphide, hypophosphite, thiosulphate, and dithionate; ammonium bisulphite; cysteine hydrochloride; titanous chloride; sulphurous acid; and mercaptan acids, salts, and glycols, and alkyl mercaptans.  Swelling agents -for example urea-and low molecular weight (> 4000) polyhydroxy compounds-for example ethylene glycol, may added to the reducing agent.

Filed: 1971-06-02
Abstract: 1330226 Welding by fusion EUROPEAN ATOMIC ENERGY COMMUNITY 2 June 1971 [2 June 1970] 18636/71 Heading B3R [Also in Division G1] The beam of an electron welding machine is focused in accordance with the intensity of the infra-red radiation emitted by the point of incidence of the beam on the workpiece 5. The workpiece is contained in an evacuated chamber 6 which also contains a chopper 9, protective glass screen 4, infra-red filter 3 and silicon photo-cell 1, chosen to have its maximum response in the I.R. region. The chopper 9 comprises a rotatable cylinder having a number of axial grooves cut in its cylindrical surface (Fig. 2, not shown), and is used both to prevent metal particles reaching the photo-cell and also to provide an A.C. output. This output is amplified at 13, rectified at 14, integrated at 15 and finally displayed on a meter 16 or a C.R.O. At low beam powers (less than 2À5 kw) the output voltage displayed on the meter or C.R.O. has a single maximum as a function of focusing current, representing the focus position (Figs. 3A-3C, not shown). At higher energies two maxima occur, and the focusing current is adjusted to give a voltage reading between these two values (Figs. 3D-3F, not shown).

Title: Improvements relating to lamps for road vehicles and the like
IPC: F21V7/00
Filed: 1921-07-14
Abstract: 188,720. Whitehead, A. C. July 14, 1921. Reflectors.-A reflector for a road vehicle lamp is made substantialy paraboloidal and of fixed focal length, and has one portion of its reflecting surface flattened as looked at from the front and proportioned and curved towards the sides so as to blend without a gap or sudden break into the surface of the other portion. The formed portion of the reflector is generated by the partial revolution of a curve of parabolic or substantially parabolic form about an axis which is inclined to the axis of the true paraboloid and oscillates during said partial revolution so as to produce a surface which reaches its maximum variation from the true paraboloidal form at its central part, which variation gradually decreases to zero at the sides where it merges into the true paraboloidal portion of the reflector surface. The inclination of the modified part is such as project the beam in or below a horizontal direction. In one form the upper part a<2>, Fig. 2, of the reflector is generated by the partial revolution of a parabolic curve a<2> about an axis x<1>, inclined to the axis x of the true paraboloid, said axis x<1> oscillating in a vertical plane about the focus h during said partial revolution. The oscillation may be made to take place about any other convenient point. In another form the inclination is varied along the curve, and is reduced along a definite plane s, Fig. 9, or the change in inclination is made continuous or in a series of steps by using a variable cam in conjunction with the template forming the generating device. In another form the inclination of the axis of generating template is combined with a reciprocating motion of the template. The filament forming the source of light is disposed as nearly as possible on the main axis of the reflector, and lies mainly between the focal point and the apex of the reflector, the upper part of which is modified. The upper part of the reflector may be made normal and the lower part modified by inclining the axis downward as before, and the filament situated mainly on the side of the focus remote from the apex. Both the upper and lower parts of the reflector may be modified, the one principally, the other to a minor degree. Other forms of reflectors formed by revolution of a curve round an axis and which with suitable sources of light can give a similar beam can be modified in the same manner. The reflector mav be mounted in the lamp body so that it may be tilted in a vertical plane to vary the altitude of the projected beam, or the whole lamp may be adjustable. The Provisional Specification states that the modification of the paraboloidal reflector may be carried out by the attachment of a supplementary reflector shaped in the desired manner.
