An electromagnetic valve assembly is shown having an armature and armature-actuated valve member the mass of which is substantially less than the armature and which is not fixedly connected to the armature; upon electrical energization the armature first overcomes a restraining force and then travels a major part of its stroke before actuating the valve member, at a relatively high speed, thereby ...

In a process of producing mechanically alloyed composite powder, a mixture consisting of at least one metallic powder and at least one non-metallic powder or of a plurality of metallic powders is ground in a drum mill in which a large amount of energy is introduced into the material being ground. To obtain composite powders having reproducible properties for mechanical technology, the powders are ...

A combination apparatus for splicing and entwining fiber slivers. A nozzle support arrangement for the nozzles of a splicing mechanism is provided and comprises essentially round rods that are adapted to be disposed horizontally one above another, with the nozzles of the splicing mechanism opening on the surfaces of the rods via nozzle outlets that are surrounded by respective raised portions of t...

Vinylcephalosporins of the formula (I) in which the symbols R<1>, R<2>, R<3>, R<4> and R<5> have the meaning given in the description.

The process comprises the steps of creating three reference points at an object and taking a tomogram of the object such that the three reference points define a first set of positional data in the tomogram. The object is then non-rigidly placed on a support for operation thereupon by an instrument which is mounted at a flexible arm containing sensors for sensing the movements of an instrument tip...

Unsaturated carboxylic acid esters having a 2E,4E stereoconfiguration (wherein X stands for hydrogen, C1-4 alkoxy or hydroxy and R represents C1-4 alkyl), may be prepared by reacting a salt (wherein M stands for a metal ion or an ammonium ion substituted by one or more alkyl and/or aralkyl group(s) and X has the same meaning as stated above) with an alkyl halide R-Y (where...

Compsn. for heat prodn. comprises (by wt.%): 50-95 of an Fe-contg. byprod. (I) of steel prodn., e.g. Fe oxide; a mineral acid; 10-25 pulverulent Al, Mg or Mn; and water. A retardant such as lime or sand may also be included. (I) is pref. \-1 of flue dust, mill scale, BOP dust, filter cake or a sinter blend. Pref. mineral acid is HCl and pref. reducing metal is Al or particle size is not 1/8 in.; i...

A solid-state electrosurgical generator is disclosed which provides output waveforms that are optimized for electrosurgical fulguration. The fulguration output circuitry consists of a radio-frequency tank circuit which is periodically pulsed to produce a periodic damped-sinusoidal output waveform. However, the damping factor is sufficiently low so that many cycles of the waveform occur between per...

This invention relates to an apparatus for applying mainly a thin rubber sheet, such as an inner liner or insulation, onto a tire making drum, which is used in a series of raw tire making processes. The apparatus can realize a proper applying of the sheet in such a manner that the rubber sheet, not previously cut to a specified length although it is longer than the circumference of the drum, is pr...

A multi-purpose tracheal tube for use with high frequency ventilation. The tube is an endotracheal tube including up to three lumens, in addition to the primary lumen, which serve various functions to provide versatility in the treatment of patients. In cuffed tubes one of the lumens is used for inflating the cuff once the tube has been placed in the desired position in the trachea of the patient....

A tire casing includes a puncture-sealing layer (2) on the inside surface thereof, the puncture-sealing layer (2) being made of rubberised interwoven flexible cords. It is due to the flexibility of the interwoven cords and the elasticity of the rubber, once a sharp object pierces the tire casing (1) and the puncture-sealing layer (2), the rubberized cords will work to tightly bind the sharp object...

In a method and an apparatus for the manufacture of reinforced ply fabric material (11, 12) for use in construction of a pneumatic tyre one or more elongate strips (11, 12) of flexible reinforced polymeric tape are wound helically around a mandrel means (36) with successive turns in contact to form a tubular structure much wider than the width of the tape (11, 12). The tubular structure is then cu...
