PURPOSE:To form a corrugated permeating plate without requiring a metal mold, press equipments or the like by folding a resin film in a bellow shape in a width set beforehand, forming the film into a corrugated shape by heating the same at a predetermined temperature while applying pressure to the same from an expanding direction, and bonding a shape holding type connecting respective top portions...

PURPOSE:To prevent short-circuit caused by the extension of a positive plate by directing the extension of the positive plate downward, and preventing the upward extension of the plate with a comb-shaped insulating member and a collapsed separator. CONSTITUTION:A protecting plate 6 has a comb-like shape having a row of slits 8 which are formed in connection with a plurality of lugs to fit the lugs...

An adapter for a swinging bucket centrifuge rotor includes a slide plate having a retaining lip and a cam surface thereon. Movement of the plate in one direction to a holding position disposes the lip to hold above the rim of a microtube to hold the same in place. Movement in an opposite direction introduces a cam surface between the rim of the tube and a flange on a closure to thereby uncap the s...

The bobbin mounting for a textile-winding machine is provided with two bobbin holders for continuous overhead draw-off of the thread. The axes of the two bobbin holders are aligned with a thread guide assigned to both of them, and one of the bobbin holders is adjustable relative to the other bobbin holder for the purpose of attaching a new bobbin. In order to make it easier to attach a new bobbin,...

In a plunger-type armature electromagnet (11), the armature (21) is guided in a pressure tube. A sensor element (33) which is dependent on magnetic field, especially a Hall element, is arranged in order to vary or regulate the excitation current of the coil (28) via an electronic control device for various attraction forces and armature positions. Said sensor element (33) is located in a projectio...

For the thread guide in textile machines, in particular for the discs of friction false twisters, a surface coating made of carbon with diamond-like crystal structure is indicated, which is superior with regard to wear and friction behaviour in relation to the previously used coatings.

The invention relates to guide elements, such as eyes, deflecting hooks, tubes, nozzles and spinning pots, for textile fibres in spinning machines, thread-extrusion systems, rewinding devices and weaving machines, consisting of electrically conductive ceramic.

In the arrangement according to the invention for the high frequency coagulation of protein, in particular for surgical purposes, the protein impedance is continuously determined during application of high frequency power and the differential quotient for the impedance curve is formed according to time. The values of the differential quotient serve on the one hand for adjusting the initial power a...

A monitoring device for a data processing system contains a timer circuit (3), which can be reset via a start input (12), and which has a first and second time lapse stage (4 and 5). An output (19) of the first time lapse stage (4) is connected to an interrupt demand input (NMI) of the DP system, and an output (23) of the second time lapse stage (5) is connected to a deactivation input (RESET) of ...

A process for converting olefins having from 4 to 12 carbon atoms into propylene wherein said olefins are contacted with an alumino-silicate having a crystalline and zeolitic structure and having a SiO2/Al2O3 molar ratio equal to or lower than 300, at a space velocity higher than 50 kg/h of olefins per kg of pure zeolite and at a temperature of from 400 to 600 DEG C, whereby said aluminosilicate i...

A powder coating process for producing soft, flexible polyurethane films particularly in the form of a surgical glove, wherein low melting crystalline prepolymer particles are powder coated and cured to an essentially non-crystalline film.

The beach umbrella is to simplify and facilitate the formation of a beach or leisure-time tent. The umbrella-type tent has, as a basic element, a beach umbrella, onto the umbrella pole of which a tent canvas can be suspended by means of rings and hooks, thus forming a complete tent which can be set up easily. The upper end of the tent canvas is provided with suspension hooks and the lower end with...

The invention relates to a shaver which has a device for counting the number of shaves which is fixedly connected to it.

A safety ski binding for holding the tip of a ski boot and capable of releasing sideways has two side jaws (13, 14) which hold the ski boot at the sides; a sole hole-down member (15), and a release spring (11) which extends substantially in the longitudinal direction of the ski. The release spring is braced at one of its ends against the binding housing (12) which is fixedly mounted to the ski and...

1. A process for the production of an insoluble sulphur-containing premixture containing sulphur, elastomer and process oil in which the sulphur and the elastomer are mixed together at a specific temperature below the transition temperature of the insoluble sulphur, in which the insoluble sulphur is dispersed in the elastomer and the sulphur has first been predistributed and the process oil has be...
