Title: Improvements in or relating to fishing reels
Inventor: HEDLUND NILS BERTIL
IPC: A01K89/0155
Filed: 1956-02-27
Abstract: 796,201. Fishing reels. HOFFMANN, K. F. E. Feb. 27, 1956, No. 6045/56. Class 48. [Also in Group XXXIV] In a fishing reel having a brake acting on the spool 13 and operated by a pivoted line-tension feeler 23 which, when the line 12 is taut, disengages the brake and, when the line slackens, applies the brake, a brake-actuating member 27, Fig. 3, is rotatably mounted on the frame of the reel and a brake shoe 37 is non-rotatable but movable towards and away from an end wall of the spool 13 and pins 35 have their ends held in engagement with facing bearings 34, 36 in the actuating member 27 and the brake shoe 37 by coupling means, such as a spring 39 urging the brake shoe 37 towards the actuating member 27, whereby the inclination of the pins to the plane at right angles to the axis of rotation of the actuating member 27 is varied as the actuating member 27 is rotated by the tension feeler 23 so that the pins move the brake shoe 37 into and out of braking engagement with the end wall of the spool. The facing bearings 34, 36 are depressions in which the ends of the pins 35 fit loosely. The actuating member 27 is in the form of a disc and is urged to rotate in a direction to incline the pins 35 at right angles to its own plane, and so apply the brake, by a spring 29. The line feeler 23 rests on the line and one of its ends 25 engages an S-shaped pin 26 extending outwardly from the actuating member 27. When the line 12 is slack the feeler is in the full-line position shown in Fig. 4 and the S-shaped pin 26 abuts a stop pin 33, the brake being then applied. When the line 12 is taut the feeler is in the dotted line position and causes the S-shaped pin 26 to abut another stop pin 32 so that the brake is off. The brake shoe 37 is a drum and carries a cork ring 41 adapted to bear against a surface 42 of the spool. The spool can be adjusted axially to control the braking effect by screwing a box 17 containing an end bearing for the spool into a sleeve 17a secured to the frame. The spool is releasably connected to a crank 15 by a gearing and a lever 14. The line is guided by a pivoted member 10 hinged to a member which engages in criss-cross grooves in a shaft driven by the crank 15.

Title: Improvements in or relating to the condensation of metallic vapours
IPC: C22B19/18
Filed: 1953-03-09
Abstract: 724,298. Condensing metallic vapours; zinc. ST. JOSEPH LEAD CO. March 9, 1953 [March 13, 1952], No. 6446/53. Class 82 (1). In a method of condensing metallic vapour from a gas stream by bubbling it through a mass of molten metal from a lower to an upper free surface, the flow of molten metal is restricted except where it is carried upwards by the gases so as to create a pressure head which is utilized to cause flow of molten metal from an upper portion of the mass through an external cooler and back to a lower portion of the mass. As shown, gases from a furnace 5 containing zinc vapour are drawn through the condenser 1 containing molten zinc connected to a suction pipe 6, bubbles of gases and vapour passing along the roof portion 8 and carrying with them a stream of molten zinc. The baffle 9 provides a large opening 10 for this stream, but the opening 11 being much smaller, the head of zinc is increased sufficiently to cause it to flow out through a conduit 16 and a cooler 17 and back to the condenser at 18. A baffle 12 also may be provided. The cooler 17 contains a cooling coil 19 through which water is passed, and which canbe raised or lowered so as to adjust the cooling effect, a temperature of 475-528‹ C. in the condenser being preferred. Zinc is tapped off periodically from the cooler, which may be modified by provision of a well connecting with an auxiliary chamber for separating off any lead which may be condensed in addition to the zinc. Specification 451,774 is referred to.

Title: Improvements in or relating to electron discharge devices employing hollow resonators
IPC: H01J25/10
Filed: 1941-05-21
Abstract: 582,616. Velocitymodulated tubes. BROADWAY, L. F., and BULL, C. S. May 21, 1941, No. 6528. [Class 39 (i)] In a circuit arrangement for mixing highfrequency oscillations in a radio receiver, an electron beam, after having been subjected to velocity modulation or passing through a hollow resonator, impinges on a target electrode which emits secondary electrons in greater number than the incident primary electrons ; the secondaries pass to a collector or to a further electron multiplier. The velocity modulation may be imparted by electrodes with which the beam is indirectly coupled or the beam may pass through grids of resonators 5, 7 which act as a mixer, local oscillations being applied to one loop 6 or 8 and a signal to the other. The beam may be circular in section and after passing the suppressor grid 9 impacts the secondary emitter electrode 10 ; the collector electrode 11 is tubular. The resonators and beam may be of the shapes described in Specifications 572,540 and 577,037. In a modification, the resonators 5, 7, Fig. 2, are built together, the discharge envelope 7d passing through them ; the suppressor grid 9 forms one of the grids of the resonator 7, the end wall of which is capacity coupled to the remainder through the plates 7a, 7b and dielectric 7c. In another arrangement, both local and signal oscillations are applied to a single resonator whose walls 12, 13 are capacity coupled ; the modulated beam falls on the target 14, which is the first of a number of multiplier electrodes which may work as described in Specification 534,208. Low velocity electrons reflected by the grid 9 may cause one of the resonators to act as a generator of self-maintained oscillations.

Title: Improvements in and relating to the treatment of regenerated cellulose products
Inventor: SHARPLES EDWIN HOLROYD
IPC: D06M13/332
Filed: 1953-03-11
Abstract: The water imbibition of regenerated cellulose products such as yarns is reduced by subjecting them in the presence of moisture, without external heating, to the action of ammonia gas or the vapour of hydrazine hydrate or of an alkyl primary amine having a molecular weight of not more than 74, and then removing substantially all the absorbed gas or vapour and excess moisture from the products.  The treatment is preferably carried out at pressures of 1 to 5 atmospheres absolute and temperatures of -20 DEG  to +20 DEG  C.  The regenerated cellulose products are preferably conditioned to a moisture regain of 25-50 per cent prior to the treatment.  After the treatment the absorbed gas or vapour and excess moisture are preferably removed from the products by drying them at a temperature above 50 DEG  C. but below that at which damage to the products may occur, but if the less volatile amines are used for the treatment the products may be washed with an organic solvent for the amine before the drying step.  The heat evolved when ammonia gas is used for the treatment may be absorbed by providing cooling devices in the treatment vessel and/or by cooling the gas before it comes into contact with the regenerated cellulose.  Examples of suitable alkyl amines are methyl-, ethyl-, and iso-propylamine, ethylene diamine and propylene diamine.  In an example, a skein of viscose rayon continuous yarn is conditioned over a saturated aqueous solution of zinc sulphate at room temperature for 3 days to a moisture regain of 27.7 per cent and then treated with ammonia gas at an absolute pressure of 60 inches of mercury and at room temperature for one hour.  The yarn is then dried at 100 DEG  C. for 15 minutes. Specifications 345,989, 486,527, and 683,203 are referred to.

Title: Method of ultrasonically testing materials at high temperatures
IPC: G01N29/28
Filed: 1963-02-20
Abstract: 1,023,513. Ultrasonic testing; ultrasonic couplings. INSTITUT DE RECHERCHES DE LA SIDERURGIE FRANCAISE. Feb. 20, 1963 [Feb. 23, 1962], No. 6753/63. Headings H4D and H4J. In an arrangement for the ultrasonic inspection of articles at high temperature an area of the surface of the article to which the test transducer is to be applied is first cooled by a flow of a cold liquid having a boiling point below the temperature of the article, the transducer then being applied to this area together with a further flow of liquid which in addition to acting as a coupling medium and cooling the transducer, flows with a velocity sufficient to prevent boiling in part of the transducer. Fig. 1 shows one embodiment in which the test head 1 is intended to be moved relative to the hot test article 2 (e.g. a rolling mill product) in the direction of the arrow. In accordance with the method of the invention the test article is pre-cooled by water discharged through pipes 4, 5 from a pressure source of 4 kg./cm.<SP>2</SP> and as the head moves relatively to the test article a further flow of water from a V-shaped outlet 14 sweeps away the, now heated, water from pipes 4, 5 thus producing further cooling of the test material and preparing it for the arrival of the test transducer comprising an annular piezo-electric capsule 11. The latter is cooled by water flowing through pipe 3 which water in addition to forming an acoustic coupling medium between the transducer and the test material also prevents the latter from becoming reheated by its own internal heat and, the velocity of flow through pipe 3 is sufficiently high to prevent the water from becoming heated to boiling point in the path of the ultrasonic rays. Additionally, the water discharged through pipes 3, 4 and 5 acts as a support for the test head. In a modified arrangement for fixedpoint testing in which the pre-cooling of the test material is effected as the test head is approached towards the latter by water flow through pipe 3a (Figs. 3 and 4, not shown) such flow, when the test head is bearing on the material at three points 22, 23, 24, then serves as the coupling medium between the material and the annular test transducer 11a in addition to cooling the latter and preventing reheating of the material by its own internal heat.

Abstract: 471,685. Making electric incandescent lamp filaments. GENERAL ELECTRIC CO., Ltd., DUDDING, B. P., and LEEDS, R. E. March 6, 1936, No. 6846. [Class 39 (ii)] In the manufacture of " coiled-coil " filaments for electric incandescent lamps the filament, prepared from plain wire at temperatures much lower than that at which the final crystal structure is attained, is mounted within a lamp and then subjected to the influence of a magnetic field while a current is being passed through it to "age" it, the object being to prevent or reduce any change of length and consequential irregularities which may occur during the ageing process. Preferably, the magnetic field is that produced by passing a direct current through a solenoid. In an example, a filament, while still on the mandrels, is heated to a temperature not exceeding 1700 C. ; the mandrels are then removed and the filament mounted in a lamp so that its median line has approximately or exactly the form of a semicircle whose plane is perpendicular to the axis of the lamp. The lamp is then placed within a solenoid and arranged with its axis coincident with that of the solenoid and a current passed through the filament until its temperature is about 2400 C., a current simultaneously being passed in the same direction through the solenoid.

Title: Method and apparatus for textile dyeing
IPC: D06B11/00
Filed: 1977-02-18
Abstract: The continuously moving textile web is coated with a dye-retaining agent, for example a vegetable gum, in a film which has uniform thickness and a syrup-like viscous consistency. A dye preparation is then continuously applied in a non-regular and non-repeating fashion to the surface of the moving textile web thus coated. In a continuous operation, the dye is then fixed on the textile web, followed by removal of the dye-retaining agent therefrom. This results in a space-dyeing effect. The costs of these processes are lower, and shading is much softer and more refined than in conventional space-dyeing processes.
