The invention relates to a method and the associated circuit for contactless marking of a nonconductor, in particular a moving textile thread or yarn. Impressed on the running thread by means of a high-voltage generator and an ionisation electrode is a discrete electric charge which is received, amplified and evaluated by a receiver which is arranged in the running direction of the thread at a dis...

A system is described for controlling clutch torque for a vehicle having a transmission, and an electromagnetic clutch 1 provided between an engine and the transmission. The system comprises an engine speed sensor 16, a computing unit 19 for measuring the speed of a driven member 9 of the electromagnetic clutch 1, an accelerator pedal switch 17 for detecting the acceleration of the vehicle and for...

A pleated fabric is connected between an upper fixed sill and a movable sill. The movable sill is between the upper fixed sill and a lower fixed sill. Two string loops are resiliently secured to the sills and slidably frictionally engaged with the movable sill symmetrical relative to the sills and to a central axis parallel to the direction of movement of the movable sill. The tension in the strin...

A pleated fabric is connected between an upper fixed sill and a movable sill. The movable sill is between the upper fixed sill and a lower fixed sill. Strings are resiliently secured to the sills and slidably frictionally engaged with the movable sill symmetrical relative to the sills. The friction engagement tends to keep the movable sill in place at whatever location the sill is moved regardless...

PURPOSE:To enhance the efficiency in a simple structure by naturally generating a smooth traveling wave by applying vibration at the prescribed position on a rod-shaped or ring-shaped article. CONSTITUTION:In rod-shaped or ring-shaped articles 21, 41, the ranges that the length is divided into two in case of the rod-shaped article, and the diameter is divided into two in case of the ring-shaped ar...

Glazing material bears a pyrolytically-formed light-transmitting solar radiation screening metal oxide coating. In order to promote abrasion resistance in a coating which has an acceptable tint in reflection due to interference effects, at least 95% by weight of the metal ions in the coating consist of tin and titanium, and the relative proportions of tin and titanium ions in the coating are such ...

PURPOSE:To permit a uniform fusion of bonded surface and betterment of appearance by providing a flexible heat insulation sheet between a heater and an easily fusible synthetic resin molded product and by heating and fusing the bonding surface of the other molded product of hardly fusible resin. CONSTITUTION:The bottom surface of a heater 3 is brought into contact with the bonding surface 11 of a ...

In a sealed cooled joint for two hollow bodies, a cooling tube of metal is arranged between the end faces of the hollow bodies, and the outer surface of the cooling tube is at least partially coated with a compressible layer of PTFE or PVDF in a thickness of from 0.1 to 1.5 mm. The joint allows a longer service life in high-temperature process units with aggressive media.

A device for reducing the surface tension of water comprises a plate (1) which serves to support a water glass (3) and into which a plurality of spaced apart magnets (2,2') is inserted flush with the upper support surface of the plate. The magnets can have alternating north-south polarity.

Method and apparatus for detecting the presence of very small concentrations of certain vapors and gases in air or other gaseous backgrounds. A gas sample is ionized by a source of ionizing radiation. The ionized gas is then directed through a first drift region where the ions are subjected to a drift potential. Electrical biased grid means are provided to allow only heavier ions of lower mobility...

An apparatus for and method of determining the content of an anesthetic gas in a selected location is disclosed which comprises heating a sensor layer containing phthalocyanine, measuring the resistance of the sensor while it is heated, and selectively determining the content of the anesthetic gas either by measuring the variation of the electrical resistance or the rate of the variation of the el...

Enteral feeding tubes are formed from the polymeric composition of, by wt, (a) 10 to 20% of a thermoplastic elastomeric block copolymer (e.g. of monovinyl arene and conjugated diene blocks) and (b) 0.1 to 12% of a linear polysiloxane (e.g. a silicone oil) of kinematic viscosity 20-10<6> cst., which mixture is known to be used for medical tubing, and (c) 80 to 90% of tungsten powder, and optio...

Dispositif pour l'extraction de produits fluides contenus dans un récipient à l'aide d'air comprimé atmosphérique ou épuré. Elle est caractérisée par le fait qu'un récipient commun (1) reçoit le produit (8) et l'air comprimé (1) et présente une connexion tubulaire (9) qui se raccorde à la tete de pulvérisation (6), une valve de fermeture (2), un gicleur (3) et un poussoir (5) repoussé par un resso...

The gas detection apparatus includes a housing (10) defining a passage for flow of gas through a drift region (30, 35, 50), a source of ionizing radiation (14) positioned at the front end of the passage, a collector electrode (70) mounted within the passage to collect ions reaching the rear end of the passage, a voltage divider network (40, 60) establishing a substantially linear drift potential i...

A single-mode optical waveguide is constructed in a manner such that the core thereof is subjected to a stress-induced birefringence. A single-mode optical fiber preform is formed by a CVD process. A pair of longitudinally extending holes is formed on opposite sides of the core, spaced slighty therefrom. A stress rod having a TCE different from that of the cladding portion of the preform is insert...
