Title: Improvements in or relating to the winding of yarn packages
IPC: B65H54/34
Filed: 1935-09-09
Abstract: 455,399. Winding yarns. BRITISH CELANESE, Ltd., 22, Hanover Square, London. Sept. 9, 1935, No. 25104. Convention date, Sept. 7, 1934. [Class 120 (ii)] In winding cross-wound packages of processed yarn onto a core, the ununiformly processed length of yarn produced at the commencement of the processing operation is wound on a part of the core not normally covered with yarn and the movement of such ununiformly processed length of yarn brings about the automatic transfer of the yarn to a part of the support removed from the firstmentioned part when the winding of the ununiformly processed length of yarn is completed, cross-winding of the correctly processed yarn then proceeding in the usual manner without cessation of the processing and winding operation. The processing operation may be a twisting, sizing, lubricating or other operation and as shown the yarn from the processing operation passes over a wheel 23 to the winding core 9. The wheel 23 is mounted on a shaft 22 rotatable and slidable in a bearing 20 pivoted on a stud shaft 19 and the shaft 22 terminates in a threaded part 24 engaging a fixed threaded bearing 18. At the commencement of the operation the yarn is wound onto the end of the core opposite the wheel 23 which is rotated by the yarn and gradually screws itself out of the bearing 18 until, when it is entirely free from the bearing, the weight of the wheel causes the wheel, shaft 22 and bearing 20 to pivot on the shaft 19 and transfer the yarn to the usual traverse guide for the completion of the winding operation. The length of yarn wound before normal winding commences may be varied by varying the pitch of the threaded part 24 and the diameter of the wheel ; a collar 25 on the shaft 22 prevents the shaft falling out of the pivoted bearing 20 on tilting of the latter. The bearing 18 and stud shaft 19 are carried by a bracket 16 screwed to the cradle 5. Specification 455,396 is referred to. The Specification as open to inspection under Sect. 91 comprises also means for governing the penetration of the shaft carrying the wheel into the threaded bearing. This subject-matter does not appear in the Specification as accepted.

Abstract: 911,276. Dispensing beverages. FOWLER, B. DE F. July 12, 1961 [July 18, 1960], No. 25285/61. Class 116. A beverage dispenser includes adjusting means for varying the length of a passage traversed by the beverage passing from an inlet to a discharge nozzle. In the dispenser illustrated, beer is supplied under pressure from a key (not shown) through a pipe 25 to a space above a piston 2 in a cylinder 1, a bypass valve 4, when open, interconnecting the spaces above and below the piston. When a diaphragm 77 is forced downwardly, by the lifting of a lever 51 by the glass to be filled, a valve 8 is opened to supply compressed-air to a diaphragm 7 to close the valve 4, and to a diaphragm 37 to open a valve 32 in the discharge nozzle 36. The piston 2 is then forced downwardly by the beer pressure so that the beer below it is forced through a spiral passageway 28 and a tube 30 to the nozzle 36. The length of the passageway 28 traversed by the beer is controlled by varying the point of entry thereinto by a rod 29 adjustable vertically by a rack-and-gear quadrant (not shown). In this manner the turbulence of the beer and hence the amount of foam formed in the glass may be controlled. Increased turbulance at the discharge nozzle 36 is prevented by providing an air vent passage in the valve 32. As the piston 2 moves downwardly a bellows 15 supporting the housings of the diaphragm 7 and of the valve 8 is collapsed, and air passes therefrom to the key to replace the beer withdrawn therefrom. A selector mechanism is provided whereby the downward movement of the piston 2 is arrested by either of two stops depending on whether a large or a small glass is to be filled. Cooling liquid is supplied to jackets 55, 31 surrounding the cylinder 1 and the pipe 31, respectively.
