Title: Threading yarn into pneumatic texturing device at high speed - using synchronised cutter and fluid jet acting pref. transversely of yarn
Inventor: BLANC CHARLES
IPC: B65H54/88
Filed: 1975-06-06
Abstract: A yarn is fed into the feed duct of a pneumatic texturing device by threading the yarn across the entry of the feed duct transversely to the axis of the feed duct. The yarn is cut with a cutter downstream of the entry and operation of the cutter in synchronized with the prodn. of a pressure fluid jet from a nozzle. The fluid jet forms a loop of yarn which moves into the entry from which it passes into the feed duct. Threading can be automatically effected at high speeds, e.g. with the yarn moving across the entry at speeds greater than 2000 metres/min.

Title: Tube for direct heating of cement powder - has circular outer pipe with square refractory inner section
IPC: F27D13/00
Filed: 1975-09-17
Abstract: Hot gases from a drum dryer pass through a series of cyclones before being exhausted. The raw material is injected into the inlet of the last cyclone where it is heated by direct contact with the gases and after separation in the cyclone is taken into the inlet of the preceeding cyclone where the process is repeated, and so on until the powder from the first cyclone is fed into the drum dryer. The cyclone inlet tubes have a circular pipe (14) lined on the inside with refractory material (15) shaped to give a square inside cross section. The tube also has cleaning openings (16) with hinged lids (17). The arrangement prevents the lining separating from the pipe as a result of differential expansion.

Patent FR-2353381-A1 (FR)
Inventor: LIPPERA NOEL
IPC: B29C65/34
Filed: 1976-06-03
Abstract: The coupling of two tubular elements is achieved by welding them together by energization of an electrical resistance element, the one element comprising a male end, the other a socket end. The coupling operation is carried out by means of a composite connecting piece comprising two rings which are fitted on one another, one acting as a support for a bifilar electrical resistance element and the other as a sheath. The electrical resistance element is thus uniformly coated in plastic material and is accurately centered, thereby ensuring uniform heating and welding. This coupling method is for use in coupling discharge pipelines for waste water and rain water and for conduits for industrial fluids.

Title: Universal railway vehicle coupling - has undercut diamond shaped portion interlocking with corresponding portion on other coupling half
IPC: B61G5/04
Filed: 1976-11-25
Abstract: A coupling for a railway vehicle incorporates some of the features of the Willison coupling used in Russia, and some of the features of the Janney coupling used in America. Each coupling half has two jaws (4, 14) which protrudes forwards with a gap between into which fits the leading part of the other half. To one side of this gap is a diamond shaped portion (3) which interlocks with a similar portion on the other half. This diamond shaped portion has a rounded forward tip (9), and is undercut (12) to permit the interlocking action. The jaw (14) at the opposite side of this gap has a swinging portion which pivots about a point (22) behind the undercut. A spring (30) holds this swinging portion in contact with the contact face (8) of the diamond portion for interlocking. A trigger arm (31) contacts another face of the diamond portion.

Title: Air distribution for public transport vehicle - has fans circulating air through closed duct in amount proportional to opening of discharge registers
IPC: F24F13/02
Filed: 1976-12-14
Abstract: A duct runs in a closed circuit at high level in a coach or railway carriage. It has inlet openings through which conditioned air enters and individually controlled discharge registers on its inside perimeter. Immediately inside each inlet opening there are fans which circulate the air round the duct. If all discharge registers are closed the fans overcome only the friction within the duct as the air follows a completely closed path. As an increasing number of discharge registers is opened, the output of the fans increases to handle the extra load.

Title: Relay for an explosive signal chain - contg. a low power fuse and using crystalline hexane as the explosive
Inventor: THIBIEROZ ANDRE
IPC: F42D1/04
Filed: 1976-12-23
Abstract: The relay comprises an axial cylinder contg. a low-power fuse with a central circular cavity and an axial chamber contg. the explosive charge. This chamber is symmetrical around the axis and forms the link between the fuse and the principal charge. The chamber is narrow at the top and wide at the bottom, the angles of the walls varying at different levels. The chamber may comprise several sections, each the shape of a truncated cone. The angle of the walls of each section are different and the sections join together to form one chamber. Alternatively the chamber may consist of one section shaped like a truncated cone and a second section with a continually but not constantly reducing dia. The equipment provides the necessary intensification of power between the fuse and the principal charge at the same time, eliminating many of the problems encountered with previous low energy fuses.

Title: Straightening e.g. circular knitted tubular fabrics - with squeeze rollers and a belt stenter
IPC: D06C5/00
Filed: 1977-07-19
Abstract: Tubular material, e.g. a circular knitted fabric, is untwisted and straightened as a double sheet; the straightened tube is fed to a pair of squeeze rollers; the tube is twisted as a double sheet through a right angle; the tubular fabric is then engaged by a belt stenter which is disposed at right angles to the squeeze rollers, to take out the folds left by the rollers. The re-folded tube then passes between delivery rollers which continuously feed a drier. On leaving the drier, the fabric is steamed and heat calendered, and finally folded. The continuous mechanical handling of the tubular fabric eliminates much manual intervention, thus speeding up the processing procedure.
