A machine for unwinding yarn from a hank comprises a base (10) for securing a swift (12) non-rotatably, and an axle (14) rotatable in a hub of the swift (12) and in a hole 15 continuing through the base (10). A rotary sweep arm (20) passes through the axle (14) and is attached therein. An eyelet (22) is connected to a lower end of the arm (20) for movement around the the swift (12) in a plane tran...

The present invention is concerned with the problem of preventing dust-formation on electrode plates of lead. The problem is solved by applying a coating of water-insoluble plastics material on the surface or surfaces of the electrode plate. Examples of suitable materials are polyacrylates, polystyrene, polyvinylacetate and polyvinylchloride. Copolymers may also be used.

The invention provides an offshore tower structure comprising a base structure for positioning on the sea bed, a central enclosed tubular column 20 containing services such as conductors and risers and extending from the base structure to above the water level, in use, for supporting a service platform 21 and at least three tubular support legs 22, 23, 24 each extending between the base structure ...

A lead-acid accumulator battery is proposed which is used as a current source or current store in motor vehicles. The lead-acid accumulator battery has a housing, in a known manner, which is common to all the cells, consists of plastic and in whose cell containers there is located in each case one plate block. On each plate block, the electrode plates of the same polarity are connected to one anot...

Oiling and mainly simultaneously acting braking device for yarns and threads during winding, in which, for the take-up of oil, the yarns and threads are guided on their surface via a relatively large number of driven rotating oil carriers, for example rollers, balls, etc., dipping into an oil bath and are simultaneously braked, in front of and behind the oiling device, by one or more dished plates...

Textile machine for the processing of yarns, in which feed bobbins are slipped on in bobbin creels. The bobbin creels are set up in planes perpendicular to the machine front and are movable in these planes. The bobbin creel is divided into sections which each comprise a feed section and a reserve section. Servicing aisles are formed between the sections.

Thread retainer in the form of a tube (34) having a slot (36) and balls (40,44) which contact each other within the slot and are relatively movable along the tube axis to permit access of a thread to a passage (38) at the inner end of the slot, and removal of the thread from said passage.

Claims for the Contracting States : BE, CH, DE, FR, GB, IT, LI, LU, NL, SE Glues based on aqueous latex of plasticised vinyl acetate polymer containing at least one polyvinyl alcohol as a protective colloid, characterised in that, in the latex, the concentration in respect of dry materials is from 50 to 70% by weight, the size of the particles of vinyl acetate polymer having a molecular mass by...

This invention concerns an improved splicer (10) to splice textile yarns mechanically, the splice being obtained by coupling two single untwisted yarns (70-71) and reapplying the twists thereafter, part of such single yarns (70-71) being untwisted until twists of a sign opposite to the original twists have been imparted, such part then being doubled and remaining tails (270-271) being obtained, th...

Equipment for continuously measuring the length of an endless material, such as a yarn, which is being wound up on a machine into a circular package, the machine comprising a movable member whose position depends upon the diameter of the package. The measuring equipment comprises a movable transfer member mechanically coupled to the movable member of the machine, and therewith cooperating photoele...

A weighing system is disclosed which operates in conjunction with a scale that has a trigger mechanism for terminating the flow of material into the scale's bucket. This system automatically periodically revises a tare signal stored in a latch circuit for combination with a weight signal to produce a net weight signal. The tare signal provides a measure of the residue stuck in the scale bucket. In...

A substantially pure compound selected from the group consisting of the d-menthyl esters of 1RS-cis-, 1RS-cis/trans-, 1R-cis-, 1S-cis-, 1R-trans- and 1S-trans-3-(2,2-dichloro- and dibromo-vinyl)-2,2-dimethylcyclopropanecarboxylic acid, the 1-menthyl esters of 1RS-cis-, 1RS-trans-, 1RS-cis/trans-, 1R-cis-, 1S-cis-, 1R-trans- and 1S-trans-3-(2,2-dibromo-vinyl)-2,2-dimethyl-cyclopropanecarboxylic aci...

This invention comprehends a new and unique means for preventing the crowns (forward projections of the pleats) of a backflushable filter element from splitting due to the cyclic aciton that is experienced during cleaning and backflushing. In one embodiment, a plurality of spacers, preferably wedge shape, is positioned between the outwardly projecting pleats of the filter media thereby preventing ...

Suspended moving control unit (2) for hoisting appliances with switches (5) and color bands (6) on the casing, as well as directional color arrows for the logic connection of the control process arranged on the hoisting appliance (for example a bridge crane (7)) and which are of the same color as the switches (5) and as the bands (6) of the casing. Experience has shown that the operator never bene...

The case of the watch comprises two plates, one formed by the back (3) and the other by the bezel (5) for the crystal and by the crystal (8), which are held apart by an annular spacer (6). These two plates overhang the spacer (6), thus creating a free annular space (9) around the case into which the strap (10), drilled with an aperture in which the case of the watch is housed, engages. The watch t...
