Each yarn end (1, 2) is held at two longitudinally distant points (3, 4; 5, 6) and an axial untwisting is introduced; these untwisted ends are brought together head-to-tail, the middle part being gripped tightly; in the untwisted part of each end between the tightly gripped middle part and the respective holding points (4, 5) of the yarn by which the untwisting was induced, an additional axial unt...

A spectroanalyzer accurately spectroanalyzes in spite of the deterioration of transmissibility of an optical fiber (5) by radiation, by using a light from a sample cell (1) as a measurement light which passes through the optical fiber (5). The spectroanalyzer comprises a white light source (15) for directing a monitoring light to a one end (5b) of the optical fiber (5), and a half-mirror (3) arran...

A vehicle engine (1) is coupled through a torque converter (2) to an automatic gearbox (3), both engine and gearbox having control units (7, 8). A torque setpoint is generated (9) in response to a signal from the gearbox control unit, and this is compared with a signal from the drive shaft torque sensor (4), the difference signal then being input to the engine controller. Thus a feedback loop is f...

The invention relates to an X-ray diagnosis apparatus for mammography having an X-ray tube (3) which is rotatable via a horizontal shaft (4) about a bearing (5) arranged in a stand (1), and at least two cassette holders (9, 10) which can be brought into a recording position when required. The cassette holders (9, 10) are pivotable about the horizontal shaft (4) in such a way that the cassette hold...

Appts. for making a three dimensional fibre resin article comprises a configured mould plate and a fibre resin tape applying head movable over the mould. The head is controlled by a first system, by which it follows programmed movements to cover the area of the mould upon which the article is to be made, and by a second system, by which the surface of the mould is sensed as the head moves across i...

A plasma sequestration system having a volume control system is provided. When a calculated volume of whole blood has been processed, the system switches from a fill to an empty cycle. The termination point is calculated in advance, based on the desired composition of the collected plasma, thus improving process control and product uniformity. The system is automated or partially automated using a...

Flexible composition on the basis of a soft polyurethane binder with a low modulus and at least one filler, which composition after curing has a possible elongation at ambient temperature of at least 50 % characterised in that it contains 0.1 to 10 wt% expanded polymerparts with a size of 2 to 300 micrometers.

The control system operates a railtrack system and has specific sections of track defined (6-17) that are related to time frames for specific vehicles (1, 2). The system is continuously monitored and the degree of overlap measured to a time-base between vehicles is determined. The degree of conflict due to the overlap is classified based upon threshold values that can be individually changed. Cont...

The orientation, path motion and control of an autonomous mobile robot (AE) is based upon monitoring of position at specific points with corrections made to account for uncertainties. The vehicle is defined in terms of a position uncertainty envelope (PV) and the movement between the start (ST) and end (2) is made in a series of sections. Objects (LM) are defined with a degree of uncertainty. At ...

The umbrella-holder has a link (2) to which the umbrella (1) is pivotally and movably fixed. The link can be locked by a clamp (7). At least one guide (3) enables the umbrella to move or turn horizontally. Another guide (6) enables the umbrella to move or turn vertically. The two guides which are telescopic or in the form of rails are locked by locks (7,8). At least one stand (9) is anchored in th...

A mattress (1) contains three superimposed upholstering bodies (21, 22, 23) and a cover (3) with three chambers (31, 32, 33), each chamber receiving one upholstering body (21, 22, 23).

The amount of nitrogen oxide (NOx) and hydrocarbon emissions emanating via the exhaust during operation of a gasoline engine is reduced by dispensing to a gasoline engine adjusted to operate primarily at an air-to-fuel ratio between lambda of about 0.9 to about 1.15, a gasoline that contains a minor amount of (i) a cyclopentadienyl manganese tricarbonyl compound and (ii) an alkyllead antiknock age...

An automatic cementing system and method are disclosed for precisely controlling the density of a slurry during a continuously mixed cement application. The system includes an input water line and a dry cement hopper for supplying water and dry cement, respectively, to a mixing chamber. The mixing chamber includes two chambers, Chamber A and Chamber B, for thoroughly mixing the water and cement to...

The present invention provides a method for manufacturing an engine gasket (11) having reduced oil permeability. The engine gasket (11) is formed in the desired shape from a silicone rubber compound having an inner surface which is to be exposed to hot engine oil and an outer surface. A silicone varnish coating is applied to at least the inner surface of the engine gasket whereby the inner surface...

A polyimide film essentially consisting of polyimide having recurring units of the formula ( I ): which has a density of 1.335 to 1.390 g/cm<3> at 23 DEG C and/or a refractive index of 1.605 to 1.680 at 23 DEG C in the direction of thickness and is transparent; and a preparation process of the polyimide film by extruding the polyimide having recurring units of the above formula ( I ) thro...

An electromagnetic shielding panel (1, 2, 3, 4, P5) incorporates at least two electroconductive coatings (10 and 6, 7,8). In two of the panels (1,2) the coatings are carried on separate sheets of float glass (5,9), one of the coatings 10 being an anti-abrasive coating is on the outermost surface of the glass (9) in the panel arrangement, while the other coating (6,7,8) being a relatively soft abra...

A crosslinked copolymer composition is derived from an aliphatic polyester, a dianhydride and a diisocyanate. The copolymer can be used as a membrane and has a high thermal stability and good aromatic/saturate selectivity and permeability.

A film easily soluble in cold water comprises a water soluble copolymer composed of 3 to 30 mol% of an allyl ester, 96.5 to 65 mol% of a vinyl ester and 0.5 to 5 mol% of an unsaturated carboxylic acid and its anhydride and having a degree of saponification of not less than 70 mol%. The film is easily soluble in cold water and such solubility in cold water does not change even if it comes into cont...

An improved thickening agent suitable for paper coating applications is a fluid suspension of 35 to 55 parts CMC or similar water soluble polymer in 40 to 55 parts fatty acid with 1 to 5 parts clay and up to 20 parts emulsifier. Handling convenience and thickening performance are improved.
