Abstract: 1,137,415. Dyeing yarns. TOYO RAYON K.K. and MARUICHI BOSEKI K.K. 13 May, 1966 [22 Sept., 1965], No. 21394/66. Heading D1L. A method of intermittently dyeing a yarn comprises moving a tensioned yarn relative to a jet of dye liquor so that the yarn is continuously advanced to and past the jet, and reciprocating the yarn relative to the jet so that the yarn passes through the jet whereby it is dyed intermittently along its length. Apparatus for carrying out the method comprises means for tensioning a yarn A, a nozzle 12 for discharging a jet of dye liquor and means for continuously moving the tensioned yarn past the nozzle 12, a traversing device 6 is also provided for reciprocating the yarn relative to the nozzle 12 so that the yarn passes through the jet of dye liquor. The yarn may be dried after dyeing and may also be steam set. A collector 23 is preferably positioned below the nozzle 12 to collect excess dye liquor which is then recirculated to the reservoir feeding the nozzle. A plurality of nozzles may be employed for dyeing a plurality of yarns.

Abstract: 637,881. Seaming non-metallic sheet material. UDYLITE CORPORATION. Aug. 7, 1947, No. 21531. Convention date, Feb. 17, 1943. [Class 42 (i)] Thermoplastic material is joined by holding surfaces to be welded adjacent each other at an angle and progressively bringing them together face to face so as to move the angled portion along a line of junction, and directing a stream of hot gas into the angle so as to soften adjacent areas of said surfaces in the angle and to form therein a bead of molten thermoplastic material which is maintained in the angle by moving the stream of hot gas along the line of junction at a rate equal to that at which the surfaces are brought together. The speed of weld and temperature of the gas are controlled so that the molten bead is maintained without charing of the material. As shown, the edges 10, 11 of two sheets 2, 1 are welded together by a jet of hot gas from a nozzle 3 ; molten material may be added to the weld by using a weld rod against the end of which the jet is directed. Alternatively, a separate strip of the same or a different thermoplastic material may be welded so as to overlie the abutting edges of two sheets. The welded surfaces may be pressed together by external pressure. The thermoplastic material may be a polymerized vinyl compound.

Abstract: 517,567. Smelting furnace plant. EVANS, O. (Rekuperator Ges.). July 20, 1938, No. 21601. [Class 51 (ii)] [Also in Group XIII] In a smelting furnace plant in which gases from the furnace 1 pass over a steam boiler 4 and through a recuperator 5 which heats the air for combustion, the resistance to flow of the gases in the boiler is considerably less than the resistance to flow in the recuperator so as to prevent the separation from the gases of molten particles of dust by cooling the gases in the boiler to below the melting point of the dust particles. The recuperator has metal tubes for the passage of air supplied by a fan 9 and the coefficient of heat transmission is increased by the maintenance of a high speed in the air flow or by throttling members provided in the path of the air. Coal dust is used as fuel.

Title: Improvements in the method of making cigar bunch charges
IPC: A24C1/02
Filed: 1944-11-06
Abstract: 581,111. Making cigar-bunch charges. INTERNATIONAL CIGAR MACHINERY CO. Nov. 6, 1944, No. 21733. Convention date, Nov. 6, 1943. [Class 130] Tobacco leaves are arranged in layers of uni- - form dimension on screens which are superimposed with the layers in contacting relationship whilst maturing takes place, and the individual layers are then transferred to the feeding mechanism of a cigar making machine. A layer of tobacco leaves is formed by depositing leaves or blended leaves, in overlapping relation, transversely across screens, comprising a frame having cord or other wide mesh, manually or by an automatic delivery device from a stripping machine such as that described in Specification 519,476. The screens are carried by a belt to a delivery point where they are placed on a truck and separated by spacers to ensure passage of heated and dried air between the screens whilst the trucks are in a drying or conditioning chamber. The screens S, Fig. 3, are then removed from the trucks and restacked in a storage or maturing chamber F without the spacers so that each layer L is in contact with the adjoining layers. After maturing each layer is transferred to a stack by placing a board E taken from a holder R on top of the layer and inverting the board and screen, the screen S finally being removed from the stack which is transferred to a truck to a cigar making machine. The leaves may be fed manually to the machine or, as shown in Fig. 4, each board E with its layer L is placed in a slide 12 which is secured to cables 28 passing around pulleys 24, 26 carried by shafts 22, 23 on supporting guides 16. During rotation of the shaft 22 by a crank handle 32 the tobacco layer is stripped from the board by a plate 34 and falls on to a feed belt 10. As the slide advances the board passes beyond bars 18 carried by the guides 16 and drops down a chute into a hopper having a retaining door which is opened periodically to deliver stacked boards on to a truck. The belt 10 is operated intermittently to feed tobacco over a bridge 56 against an adjustable stop plate 70 and strips cut off by a knife 58 are overlapped on a belt 60. Bunch lengths sections are cut out by a corrugated knife 72, lowered by a platform 74 and pushed on to a feeding table 76 by a plunger 78. To produce blended cigars, blending tobacco is laid on the layer either before its transfer from the screen to the board or immediately after, near the end which forms the lighted end of the cigar. U.S.A. Specification 1,740,571 is referred to.

Damping-arrangements for indicating and recording apparatus.-In a measuring instrument in which the bearings for the moving system are mounted on resilient supports, a mechanical damping device is provided in order to prevent the system from having a period of vibration with which it would respond to impressed vibrations or a succession of shocks. Fig. 2 shows the invention applied to an electrical measuring instrument cf the D'Arsonval type having a moving coil 10, and a permanent magnet. The coil 10 and its pen or pointer 18, with balance weight 19, are mounted in jewel bearings 13 carried by a stem 14 which is resiliently supported by springs 15 as described in Specification 14214/15. [Class 37, Electricity, Measuring &c.]. The moving system is prevented from vibrating in any natural free period by a filling 21 of spongy rubber arranged to surround the stem 14. The filling is retained in the centre of the soft iron core 16 of the instrument by washers 22 of kid leather or other material.
