Title: Wind driven rotor with hinged blades - has horizontal axis of rotation at right angles to wind direction
IPC: F03D3/06
Filed: 1974-11-06
Abstract: The rotor is mounted on a horizontal shaft (1) with a hub (2) carrying eight spokes (3). Each spoke (3) is provided with a pair of hinged blades (4).

Title: Polymerisation of lactams to polyamides - in presence of metal oxide activators
IPC: C08G69/20
Filed: 1975-12-05
Abstract: Prepn. of polyamides comprises polymerisation of lactams in presence of metal oxides as activators, in amt. of 0.1-50 (5-20) wt. %. Polymerisation is carried out in air or an inert gaseous medium under vacuum down to 10-5 torr or pressure up to 3 atmos. and may be accelerated by exposure to ionising radiation. Reaction time is reduced compared with the usual hydrolytic process in presence of acid activators, and no breakdown of polymer occurs during processing. The one stage process simplifies mfr. and use of continuous working. High-pressure equipment is unnecessary and mechanical properties are improved, e.g. wear resistance by around 5 times. The polymer is simultaneously filled and coloured by the metal oxide.

Title: Spinning device has traverse guide feeding roving into roll nip - and yarn breakage guide moves to stop feed of roving into nip
IPC: D01H13/18
Filed: 1976-04-01
Abstract: Device includes a drafting mechanism comprising a series of embossed rollers forming nips with presser rollers into which a fibre roving is fed via a funnel which traverses axially along the nips so that as the roving passes through the nips it is twisted into yarn. The twisted yarn passing from the last nip which is associated with a suction tube to remove waste fibre, passes over a sensor pref. a mechanical feeler which when the yarn breaks, actuates a stop-motion mechanism to (1) firstly move the funnel outside of its normal transverse path so that roving is no longer fed into the first nip; and (2) secondly the move the presser rolls so that pressure is no longer exerted on the partially twisted yarn. The spinning device is automatically stopped when yarn breakage occurs. Waste yarn does not entangle around the rollers.

Title: Texturing multifilament yarns by blow entanglement nozzle - with heat fixing to eliminate shrinkage capability enhancing fabric quality
Inventor: BRUN JACQUES
IPC: D02G1/16
Filed: 1976-05-28
Abstract: In a continuous texturing process, a yarn comprising multiple endless filaments is overfed through a turbulent zone set up by a jet of fluid under pressure. This separates the elementary filaments and entangles them with each other. Before being rebound, the yarn is subjected to a controlled thermal fixing treatment combining the action of heat and tension. The temp. applied to the yarn is 140 degrees - 250 degrees C whilst the relaxation of the yarn may be controlled either by overfeed or underfeed. The machine has treatment stations each of which includes, a yarn supply point, a yarn feeder, a texturing nozzle connected to a source of blowing fluid, a yarn take-off device linked to the yarn feeder by an arrangement permitting the adjustment of a constant and variable ratio between them, and a heat treatment arrangement through which the yarn runs to a feeder for the rewinding point. Heat is transmitted to the yarn by contact or radiation from surfaces heated electrically or by a circulating fluid and a constant but variable ratio is maintained between the speed of the rewinding feeder and the yarn take-off at the blowing nozzle. Process eliminates the capacity of yarns produced by similar techniques to shrink considerably under heat, so that they can be used much more widely for woven and knitted fabrics.
