A method for preventing abnormal splicing. When two or more yarns are sucked from the package by the suction arm or when a slab or other disorder is detected by the detecting device, the yarn is cut in response to a yarn cutting signal from the detecting device, and after completion of the splicing operation, the yarn is forcibly cut again and the splicing operation is conducted again.

A rotatable processing bowl-type apparatus for separating blood components where a plurality of flexible umbilical tubes are positioned to establish communication with a processing bowl at one end thereof. Certain segments of each of the cables are stiffer than other segments of the same cables for improved life and performance. Also, outer portions of portions of the cables are impregnated with s...

A safety ski binding and a method of laterally releasing the boot. The binding includes a jaw holding one end of the boot and adapted to laterally pivot, and a support fixed to the ski. The support forms two downwardly converging lines of support around which the jaw pivots. In one embodiment, the support comprises two projections positioned symmetrically with respect to the longitudinal and verti...

The shaping former (for radial carcasses) comprises a rubber bladder (16) and bead-gripping devices (13, 14). The expansion of the bladder is accurately controlled by the provision of centralising means comprising a restraining band (18) formed from a series of links pivoted together like a trellis and held in central position by an array of inextensible wires (17) each of which extends between th...

The invention relates to a radio-frequency surgical instrument having a radio-frequency generator as well as at least in each case one electrode terminal for monopolar active electrodes, bipolar electrodes and a neutral electrode and a control device for switching over between bipolar and monopolar operating modes. The aim of the radio frequency surgical instrument is to enable both monopolar coag...

In a process for the manufacture of composite material comprising a matrix of set inorganic binder (e.g. Portland cement) and reinforcing fibre (e.g. carbon fibre), by de-watering a slurry containing water-settable inorganic binder, reinforcing fibre and web-forming fibre (e.g. cellulose fibre), and subsequently setting the binder, a ball clay is included in the slurry that is de-watered, in order...

PURPOSE:To contrive miniaturization of a reactor by leading out terminals from plural windings respectively and selecting each of those plural terminals or enabling to connect them mutually, thereby obtaining various kinds of inductance by one reactor and facilitating change of the capacitance to be required. CONSTITUTION:An inside winding 1 and an outside winding 2 are arranged concentrically in ...

Caliper brake apparatus has a caliper housing, an actuator including a plunger movable axially longitudinally to urge a lining against a rotating disc, and the lining having the form of a plate which is laterally elongated and defines a plane generally perpendicular to said axis. The apparatus is improved by: (a) the plunger having cross sections in planes normal to said axis and characterized as ...

A closure assembly comprising a sleeve and a flexible elongate fastening member (1) comprising first and second wire-like or rod-like gripping portions arranged substantially parallel to, and laterally spaced from, each other with their lengths disposed substantially relative to the fastening member and connected to each other by a plurality of wire-like or rod-like connecting members which lie su...

An hydraulic actuator comprises a fluid inlet (31), a first piston (3) and second piston (4) both working in a bore (2) in a housing (1) and incorporates a pressure proportioning valve (5). The valve (5) comprises a valve head (13) for engagement with a seating (21), first and second stems (14, 28) projecting from the head (13) and through the first piston (3) in each of two opposite directions, e...

Films which are clear, transparent, non-tacky, easily handleable, mechanically strong and stable at both low and high humidity conditions, and are rapidly soluble in cold and warm water are formed from blends of water soluble polyvinyl alcohol (partially hydrolyzed polyvinyl acetate) and polyacrylic acid, optionally with a plasticizer. The films are also heat sealable and biodegradable.
