Title: Improvements in or relating to Filaments of Highly Refractory Metal.
IPC: H01K3/02
Filed: 1918-11-26
Abstract: 121,595. Westinghouse Lamp Co., (Assignees of Smith, H. H.). Dec. 19, 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Filaments of refractory metals such as tungsten and molybdenum are heated, before use, to such a degree that long interlacing crystals are produced and subsequent sagging of the filaments is prevented. The temperature of treatment is de. scribed as the " germinative temperature," at which the grains of material can coalesce. It depends on the composition, texture, and prior treatment of the metal. In the case of a filament of tungsten containing 2-7 per cent by volume of silica and 1-4 parts per thousand by volume of thoria, this temperature is 1170 C. For a gasfilled lamp above 100 watts capacity, the treatment may be effected by passing through the tungsten filament 90 per cent of the normal current, increasing the current during one minute to 130 per cent, and maintaining this current for one minute.

Title: Process and apparatus for the production of fancy yarns
IPC: D01D5/20
Filed: 1963-05-16
Abstract: 1,018,964. Knopped filaments. TEXTILE CHEMICAL RESEARCH CO. Ltd. May 16, 1963 [May 16, 1962], No. 19570/63. Heading B5B. Apparatus for the production of a fancy yarn having more or less regularly spaced knops comprises a spinneret (not shown) adapted to be immersed in a spinning bath and adapted to form a bundle of filaments, a straight spinning tube 1 centred on the spinneret and also adapted to be immersed in the spinning bath and an ejector within which the tube is located, the ejector comprising a Venturi flow tube 13 around the axial tube 3 which extends the spinning tube 1 to beyond the constriction 15 of the Venturi tube, and fitted with a lateral nozzle 24 for the supply of a complementary bath to the ejector upstream of the Venturi constriction, and a withdrawal device adapted to withdraw yarn from the ejector at a reduced rate. In operation, a strong stream of spinning bath is passed through the tube 24 into nozzle 22 and opening 21, and through the perforated disc 19, thus drawing the spinning bath from the tank through the tube 1 which passes through the tank wall 2, and hence the filaments supplied by the spinneret. The yarn is ejected at high velocity into the outlet nozzle 13 and is withdrawn therefrom at reduced speed by withdrawal members. Owing to the slowing down of the bath flow caused by the contour of the Venturi tube, an accumulation of yarn is produced in the nozzle 13 and at the outlet thereof, and withdrawal at reduced speed thus causes the formation of knops. Variations in the size or frequency of the knops is attained by modifying the rate of flow of the complementary bath, the contour of the nozzle 13, the withdrawal speed of the yarn, the rate of delivery of the spinning solution or the number of filaments. Support yarns may be spun concurrently with the knop yarns. In Examples, a regenerated cellulose knop yarn and support yarn are made by wetspinning viscose into a Muller bath.

Title: Improvements in or relating to nut-crackers
IPC: A47J43/26
Filed: 1944-10-17
Abstract: 592,232. Nutcrackers. RIMES, C. L. Oct. 17, 1944, No. 20039. [Class 128] One jaw of a pair of nutcrackers forms part of an enclosed loop in which the other jaw is slidable and the closing of the jaws is progressive by predetermined amounts and is effected by the relative movement of a pair of handles. As shown in Fig. 1, the movable jaw 1 is comprised by the head of a plunger 2 displaceable within the arms 3, which are channel shape in X-section to provide guides of a U-shaped frame 4 the loop 5 of which comprises the fixed jaw 6. The stem 10 of the plunger 2 is of rectangular shape in X-section and has grooves 11 with which mesh pins 11<x> for guiding purposes. The plunger is displaced towards the fixed jaw 6 by the relative movement of the handle 12 towards the handle 13, the handle 12, pivoted at 14, acting on a resiliently loaded pawl 15 pivoted at 16 to engage ratchet teeth 17 on the stem 10. A resiliently loaded retaining pawl 18 prevents retraction of the plunger when the handle 12 is allowed to return to its original position under the action of a spring 19. As the handle 12 takes up its original position the pawl 15 retracts to engage a lower disposed tooth on the stem 10. To move the jaw 1 away from the jaw 6 a projection 21 is formed on the plunger and when handle 12 is at its maximum distance from handle 13 (see Fig. 4) the pawl 15 is drawn away from the rack teeth 17 by projections 15<x> engaging a cam or inclined face 22 on the frame 4. The plunger 2 can then be moved from the jaw 6 and the pawl 18 rides over the rack teeth 17a. In a modification, Fig. 6, the handle 12 is formed with a cam projection 23 engaging secondary levers 24, pivoted at 25, which pass under lugs 26 on the pawl 15 carried by a vertically movable extension 28 guided by a pin 29 and slot 30 within the handle 13. A spring 31 acts to return the pawl 15 after each upward stroke and keep it normally in contact with the teeth 17a. A spring- loaded catch 18 engages the teeth 17a to prevent its retraction whilst further cams engage lugs 33 on the pawl 18 when the handle 12 is moved towards its fully open position and further movement disengages the pawl 18 which in turn engages the pawl 15 through lugs 33 to force the pawl 15 also out of engagement with the ratchet teeth 17a (see Fig. 9).
