Title: Apparatus for casting a microwire in glass insulation
Inventor: ZABOROVSKY VITALY IPPOLITOVICH
IPC: H01B13/00
Filed: 1966-06-16
Abstract: 1,157,313. Automatic resistance control. VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY ELEKTROTEKHNICHESKY INSTITUT. June 16, 1966, No.19261/66. Heading G3R. In an installation for casting a wire in glass insulation, metal and glass are melted in a microbath heated by an inductor of a H. F. generator and the installation includes a device for monitoring the characteristic impedance of the wire. In Fig. 1, devices 12, 6 respectively feed glass tube 14 and metal rod 10 to a high frequency induction heater 4 from which a glass-insulated wire 16 is drawn, cooled by oil from a pump 30, and wound on a bobbin 20 by gear 18. The input impedance of the wire relative to the earthed bobbin 20 forms part of an electronic valve oscillator-supplied bridge circuit 22 the amplified output of which, by its unbalance, operates an ohmmeter and controls, through limited follow-up servosystems 24, both the speed of winding gear 18 and a vacuum pump 31 associated with heater 4 to determine its temperature. Wire resistance is thus maintained equal to an adjustable reference value and the voltage across the coil of heater 4, which varies with the amount of material being heated, may control device 6 to maintain the feed of metal in correspondence with the selected value of wire resistance. A suitable arrangement involving magnetic amplifier controlled ratchetdriven metal and/or glass feed rollers on flexible shafts with a calibrated adjustable gap between them is described. Absence of the wire, e.g. due to breakage, is detected by a radio-frequency detector 28 which thereupon ensures that the winding and feed speeds and temperature are maintained at manually adjustable datum values until the wire is restored. Manual controllers and indicating, recording, and alarm devices are provided.

Title: Improvements in and relating to dyestuff preparations, and the dyeing of cellulosic materials such as paper, therewith
IPC: C09B69/06
Filed: 1949-07-22
Abstract: A dyestuff composition comprises a dry powdered mixture of a basic dye, a heteropoly acid known to be capable of forming a lake with a basic dye and a dispersing agent.  Anionic dispersing agents are preferred and sodium lignin sulphonate and sodium salts of condensation products of naphthalene sulphonic acid with formaldehyde are specified.  Preferred heteropoly acids are phosphomolybdic or phosphotungstic acid or a phosphomolybdotungstic acid or such an acid in which all or part of the phosphorus, molybdenum or tungsten is replaced by vanadium or selenium.  The so-called reduction products of heteropoly acids cf. Specification 313,209, [Class 2(iii)], are also mentioned. Aqueous dispersions of the composition are preferably made by forming it into paste with cold water, adding to hot water and subsequently boiling.  More than one basic dye and more than one acid may be present.  The preferred relative proportions are 30-50 parts of dye, 40-60 parts of acid and up to 20 parts of dispersing agent.  The products are used in the dyeing of cellulosic materials, e.g. paper and textiles, when other substances such as binding or stiffening agents, e.g. water-soluble gums or starch, may also be present in the dye-bath. They may be used on paper pulps such as bleached sulphite, esparto and rag pulps.  Paper may be dyed during its manufacture, e.g. by adding the composition to the pulp, or after manufacture by padding through, or coating with an aqueous dispersion of the composition.  In examples, preparations are given of (1) auramine O 150 per cent, (2) Rhodamine B 500 per cent, and (3) mixed auramine O 150 per cent and malachite green, the dispersing agent in each case being a sodium salt of a naphthalene sulphonic acid condensation product with formaldehyde and aqueous dispersions of these preparations together with other ingredients, e.g. starch, alum sulphate, casein and barium chloride are made in (4), (5) and (6) by the above preferred process and used for coating and dyeing paper.

Title: Improvements in hydraulic brake apparatus
IPC: B60T13/18
Filed: 1926-08-04
Abstract: 256,623. Schaede, H. Aug. 4, 1925, [Convention date]. Fluid-pressure.-A hydraulic brake system comprises a pump which normally circulates liquid freely, and a valve which is adapted to be held closed so as to establish a predetermined pressure in the system whereby this pressure is first applied to the smaller of two pistons connected to the brake blocks to bring the blocks up to the wheels and then to the larger piston to apply an increased pressure thereto. The pump normally circulates liquid iu a circuit comprising a reservoir 4 containing a freely movable piston 16, pipes 5, 5' and a valve 7. If a. pressure P is applied to the lever 13. a pressure equal to 2P is applied to the valves 7, 8 respectively. Liquid is thus forced into the smaller cylinder 15 at a pressure P to bring the brake blocks into contact with the wheels. The reservoir 4 is at the same time emptied and if the liquid contained therein is insufficient, further liquid is drawn from the reservoir 19 past the valve 18. The larger piston 20 is also moved by the piston 9 and liquid is drawn into the cylinder 10 therefrom from the reservoir 19 past the non- return valve 22. When the shoes have thus been applied the pressure is transmitted to the larger piston through the by-pass 23. The play of the brake shoes is determined by the, capacity of the reservoir 4 which can be adjusted by a screw 25 engaging the piston 16. The desired pressure may be applied to the valve lever 13 mechanically, hydraulically or electrically. This pressure may for example be applied by a spring acting in opposition to an electromagnet the strength of the current in which determines the actual pressure. With this arrangement the brakes are. applied automatically in the, event of breakage of the couplings of a train,

Abstract: 220,786. Hollingworth, E., (Crompton & Knowles Loom Works). July 28, 1923. Stop-motions, warp.-In a warp stop-motion of the type comprising drop wires 21 having slots with narrow upper ends co-operating with oscillating detector rods 20, a moving member 14 acts either to oscillate the detector rods or to operate the knock-off mechanism. The member 14 has pivoted thereto a hook member 29 provided with a notch 28, which normally receives a pin 17<a> carried by a link 18 connecting the various detector rods. On the occurrence of warp failure, the pin 17<a> cannot be moved and the hook 29 as it moves to the left rides over it and is raised to engage a dog 25 pivotally carried by the knock-off lever 23, which is thereby actuated to stop the loom. As the knock-off movement nears completion, the dog 25 is raised by a cam surface 35 on its overhanging arm 33 wiping over a support 34, and the hook member 29 falls and its second notch 30 engages the pin 17<a>. A stop 3& limits the movement of the link 18 to the right, so that when the loom is restarted, the notch 28 is again caused to engage the pin 17<a>.

Filed: 1973-04-25
Abstract: 1362362 Feed by clamps; work holder GERBER SCIENTIFIC INSTRUMENT CO 25 April 1973 [26 July 1972] 19601/73 Heading D1G [Also in Division B3] A method of making a contoured work clamp comprises the steps of positioning a blank B in a programme controlled machine, attaching a tool 50, causing the apparatus to produce relative movements between the blank and tool in accordance with the apparatus programme to guide the tool along a path similar to the path normally followed by the work tool, and cutting the blank along the path. The apparatus comprises a sewing machine 16 and computer 12 with a tape reader 20, which actuates motors 40, 42, for controlling the movement of superposed slides 34, 36, via belt drives. Milling tool 50 rotated by a motor 52, is attached to the sewing machine 16, and blank B is positioned on a support 30, and since the milling tool is offset in the Y direction relative to the needle in the sewing machine, a compensating factor is required to be introduced in the sewing programme so that tool 50 follows the stitching path P on the blank. In a modification, tool 50 is mounted at the needle position and no compensation is then required. In a further modification, blank B is mounted on Y-carriage 36 with an offset equal to that between the needle and tool 50, and no compensation is required. Y-carriage has a magnetic plate 60, a pair of alignment pins 62, and a slotted guide bar 70, for mounting and setting support 30, using index marks 74, 76. In the aformentioned embodiments the required shape of work clamp is machined by tool 50; however this tool may be a pencil, awl, or other scribing tool, with the machining operation being subsequently carried out using the marked out contour as a guide for the cutting tool. The programme may include a cam, and several stacked clamps may be machined together.

Title: Improvements in, or relating to, animal restraining appliances
IPC: A01K1/06
Filed: 1960-05-13
Abstract: 889,938. Animal restraining appliances. DE FILIPPI, G. B. May 13, 1960 [May 16, 1959], No. 16907/60. Class 81 (2). An animal restraining appliance comprises one or more forked units 13 which are rotatable and bend to depend from an elevated horizontal rail 14, there being co-operating adjustable stops for determining the direction in which the or each forked unit may be turned about the rail. The rail 14 is rotatably supported on two or more spaced pillars 10c so that it is spaced above railings 10, 10a, 10b separating the animals from a manger by a distance B which is sufficient to receive an animal's head. In each of the spaces between adjacent pillars there is an open-topped gap in the railings of a width A which is only sufficient to receive an animal's neck. A forked unit 13 is rotatable on the rail above each gap in the railings, collars 16 adjustably fixed on the rail preventing movement of the units along the rail. Each collar carries a stop 17 in the path of rotation of an arm 13a of the corresponding forked unit. The rail may be rotated by a flanged head 18 which has four holes 18a selectively engageable with a fixed screw 20 to hold the rail in one of four positions. The position of the stops may thus be adjusted relative to the forked unit so that (a) the forked unit swings freely to enable the animal to pass its head between the rail and the railings in either direction; (b) the forked unit can be supported by a stop above the rail so that the space between the rail and the railings is unobstructed; (c) the forked unit cannot be swung towards the manger so that the animal cannot reach the manger; or (d) the forked unit will only swing from its vertically depending position towards the manger so that once the animal has passed its head between the rail and the railings it cannot withdraw it. The collars 16 are independently adjustable so that one or more forked units may be independently controlled by the stops. The railings and pillars may be replaced by brick or masonry.

Title: Improvements in or relating to signalling or alarum devices for road, or street crossings or corners
IPC: G08G1/02
Filed: 1926-08-10
Abstract: 269,383. Hoare, C. C. Aug. 10, 1926. Road signals.-In apparatus for signalling the approach of a vehicle towards a cross-road &c. bars C, C' are actuated in turn by the wheels of the vehicle, the first closing a signal circuit, and turning a pivotally mounted controller G, while the second operates a controller resetting device such as a bar E. A lug A <4> on a pivoted extension A<1> of the plunger A actuated by the bar C engages an arm G<1> to turn the controller and bring a lug G<6> into position to support the bar E and prevent a notch E<2> on the bar engaging a tooth F<1>. The controller is also moved sidewavs by a wedge A<7> so that an arm G<3> clears a projection E<4> on the bar E, a spring stop G<4> and the projection E<4> holding the controller in this position after the plunger A has been raised by a scring A<6>. Actuation of the bar C' causes the bar E to deflect the extension A<1> but the bar is prevented from dropping by the lug G<6>, and on its return movement pulls back the controller by the projection E<4> engaging the nose of the arm G<3>. When a vehicle is proceeding away from the cross-road &c., the plunger B is depressed first, and causes the bar E to deflect the extension A<1>, thus preventing a signal being given when when the plunger A is subsequently depressed. The bar E falls, since the lug G<6> is not in a position to support it and is prevented from returning by the engagement of the notch E<2> with the tooth F<1>. As the extension A<1> rises, a tooth A' engages the point of the bar E, which is then withdrawn by the return of the plunger B. Duplicate sets of mechanism may be placed across the width of the road and may operate one or two signals. The signals may be visible or audible, and are effected by the closing of the contacts D<1>, D<2> on the depression of the rod D.

Abstract: 147,812. British Thomson-Houston Co., (Assignees of Bergman, S. R.). Jan. 16, 1917, [Convention date]. Exciting; pole - pieces, cores, and yokes.-A dynamo 10 serving as a motor for starting an engine 17 and afterwards as an engine-driven generator for battery charging and lighting, has a two-part series field winding, the part 20 consisting of a few turns of low resistance and the part 21 consisting of a larger number of turns of higher resistance. The part 20 is used alone for motoring and both parts in series for generating. A shunt coil 13 is also provided. At starting, the winding 20 is connected to the battery 14 by a. switch 23 actuated by hand or foot. When the engine starts and attains sufficient speed, the electromotive force across the armature brushes 11 rises and a coil 30 connected across these brushes receives sufficient current to close a switch 25 connecting the high-resistance winding 21 in series with the winding 20 and the battery through a coil 31, which holds the switch 25 closed as long as the engine speed is sufficient. In a modification, the winding 21 is in two or more parts, one or more of which may be connected to the switch 25 by a hand switch. In order to neutralize the armature reaction, the field winding may comprise a number of spaced conductors 20<c> connected to a single group of return conductors 20<e>, Fig. 5, the conductors being wound in slots in laminated pole-pieces of the kind described in Specification 104,197. In a modification, the conductors are wound in slots in the inner periphery of the pole-pieces. Specification 147,807 also is referred to.
