Yarn is wound onto a core at constant rate to form a package using a traversing yarn guide. The mean value of the traversing speed is increased from the initial value to a predetermined max. mean value so that this is reached when a base layer is produced adjacent to the core with a thickness of no more than 10% of the total yarn thickness of the finished package. The max. speed is pref. maintaine...

1. Installation for the point-to-point transmission of data between the track and a vehicle travelling on this, consisting of ground equipment (5) fastened to the track and comprising a transmitter which transmits the coded information from a track signal (11) by means of a transmission marker (9), and of on-board equipment (1) accommodated in the vehicle (3) and comprising a receiver (151, 152, 1...

A snap hinge closure connects two parts, such as, for example, a lower and an upper part of a closure. Both parts have casing walls which, in the closed position of the hinge, match vertically above one another. On both sides of the film hinge, tension bands are positioned, which, in the closed position, are tensed. The tension bands are held, with their ends, in recesses (11) in the casing walls,...

PURPOSE:To improve brightness and lower luminescence starting voltage by applying preset heat treatment and using a specific luminous layer with preset exciting spectrum. CONSTITUTION:A thin film electrode, an electric insulating layer, a luminous layer thin film, an electric insulating layer and a thin film electrode are formed in sequence on a substrate. A fluorescent substance to which active a...

This invention consists of a range of easily attachable, disposable and sterilisable caps which can be fitted onto the output end of laser therapy heads to prevent the spread of transmissible diseases during laser therapy treatments of humans and animals over a range of laser wavelengths at power levels across the electro-magnetic spectrum whilst maintaining laser beam intensities of less than one...

A prefilled syringe is disclosed which comprises a syringe body with a slidable piston defining a compartment therein containing a substance to be injected. An injection needle is arranged for communicating with said compartment through said piston and sleeve means are provided around the needle in slidable relationship with said syringe body. A compression spring is urging the sleeve means in a p...

A novel antitumor antibiotic of formula (I) designated BMY-41339 is produced by fermentation of certain strains of Actinomadura verrucosospora. BMY-41339 exhibits antimicrobial activity and also inhibits the growth of tumors in experimental animals. 1

A venetian blind, for example for mounting between the panes of a multi-glazed window assembly, said blind comprising upper and lower elongate supporting members (31, 32) extending across all or part of the width of the blind means (25) for pivotally mounting said supporting members (31, 32) about their longitudinal axes with respect to upper and lower structural members (12, 13), slat supporting ...

Thermoplastic fibres, such as polylethylene fibres, are added to cellulose fluff pulp in a mill in which the fibres are disintegrated and the mixture homogenized. In accordance with the invention, the thermoplastic fibre material is first introduced into a controlled humid environment and thereafter fed to the mill in a wet state. Such pro-treatment of the thermoplastic fibre eliminates variations...

An oxidizable base metal is fired in the presence of an organic mdeium to volatilise the medium without oxidn. of the metal by heating in an atmos. of CO, CO2 and 0.1-90 mol % water on CO2, at a temp. between the metal/metal oxide and C/C oxides phase transition lines of the resultant gas mixt. The base metal is pref. dispersed in a solid polymer or liq. paste matrix. The oxidizable metal is pref....

A sample and hold circuit (10) receives a low level analog input signal and is gated by a clock (18). The output of the sample and hold circuit (10) is summed with a signal from a noise source (22) and the resulting signal coupled to an analog to digital (A/D) converter (24). The noise source (22) presents a bandwidth restricted signal having no substantial energy in the range of frequencies of th...
