Abstract: A thermoplastic polyolefin substrate, preferably polyethylene or polypropylene, is joined to an ethylene-propylene polymer, preferably an ethylene-propylene-diene elastomer, by first locally preheating only selected portions of the surface of the thermoplastic substrate while maintaining the rest of the surface and of the substrate at a substantially lower temperature, then applying to substantially the entire surface of the substrate an unvulcanized layer of the ethylene-propylene polymer, and finally heating the elastomer layer and thermoplastic substrate to the vulcanization temperature of the polymer to vulcanize and/or cross-link same and to unitarily bond the layer and substrate together on the surface at the selected portions thereof but not on the surface between the selected portions. Thereafter the polymer layer and thermoplastic substrate are cured by cooling. A filter plate for a press filter can be made with this method.

Abstract: Method and apparatus for the edge grinding of a glass pane in which a grinding wheel is guided to the glass pane so that a grinding point is defined therebetween which travels along the edge of the rotating wheel. Cooling during grinding is provided by a coolant jet dispensed from a nozzle whose end is essentially pointed towards the grinding point. Via a respective control unit, the coolant jet is caused to follow automatically and precisely the movement of the grinding point.

Abstract: A substrate having an appearance similar to that of nubuk-leather or pile-leather, respectively, or of a textile pile consists of a textile carrier body being at least partially impregnated with a, preferably cross-linked, polymeric synthetic plastics material consisting of a foam which has open cells formed by introducing air and optionally has closed cells formed of hollow microspheres. The textile carrier body consists of a fleece or of a knitting, preferably of a crimped fleece of synthetic fibres, which is needled together with a knitting or with a fleece, strengthened by thermal embossing, in such a manner that the fibres extend through the knitting. The knitting may consist of a roughened stockinet, i.e. a stockinet having opened loops. The carrier body is ground at least at its one impregnated surface and is thus rough and can be provided with a coating.

Abstract: An adapter assembly for the connection of coaxial cables in which an adapter body having a rear side is formed with at least one pass-through opening, and at least two hook-shaped catch fingers projecting from the rear side adjacent the opening and whose hooks open toward one another. A respective socket is received in the opening and formed with a polygonal limiting flange resting against the rear side and retained by a snap-action grip of the catch fingers over the flange so that the hooks engage a rear side of the flange, the hook-shaped catch fingers having a diametrical spacing from one another across the opening substantially equal to a spacing across the flange between opposite sides thereof. Torsion force takeup for coupling or decoupling with the socket is ensured by a pair of bars or projections from the rear side which engage the preferably hexagonal flange and are offset from the fingers.

Abstract: An electric hair styling tong includes a pair of elongated arms pivotally articulated to each other at one end and each carrying at its other end an electrically heated pad arranged with its face confronting the face of the other pad and with the face of one pad being smooth for hair straightening and the face of the other being undulating for hair crimping. An intermediate arm movably mounted between the articulated arms carries an intermediate plate provided on on side with a smooth face selectively engageable smooth pad face and on the opposite side with an undulating face complementary to and selectively engageable with the undulating pad face. The intermediate arm may be selectively latched to one or the other of the articulated arms to maintain either the confronting undulating faces or the confronting two smooth faces in engagement, enabling the other of the confronting smooth or undulating faces to be used to treat the hair.

Abstract: A process is described in which catecholborane is produced by a reaction of a phenolic compound with a boron hydride in a solvent. Tris(catecholato)bisborane, i.e. the ester of boric acid and catechol, is reacted with an alkali metal-boron hydride in an aliphatic ether. A lithium halide is suitably used too, where sodium-boron hydride or potassium-boron hydride is employed. In a preferred embodiment, the reaction is carried out in conjunction with an activating grinding operation.

Abstract: An aqueous effluent is supplied to a stripping column (total stripping column) from which a mixture that is rich in NH.sub.3, CO.sub.2 and H.sub.2 S is withdrawn as a head product. In at least one additional stripping column the mixture is separated into a mixture which is rich in NH.sub.3 and a mixture which is rich in the sour gaes CO.sub.2 and H.sub.2 S. The mixture which is rich in NH.sub.3 is scrubbed with liquid ammonia. The overhead product from the total stripping column is cooled in a condenser under a pressure of 1 to 7 bars and is thus transformed into a liquid phase to such an extent that the liquid phase contains 70 to 100% of the NH.sub.3 which has been supplied to the condenser. The liquid phase is supplied at a temperature of 30.degree. to 90.degree. C. to a second stripping column (NH.sub.3 stripping column), which is operated under a pressure of 1 to 4 bars and from which a gas mixture that is rich in NH.sub.3 is withdrawn as a head product.

Carbon dioxide is used as the oxidizer and organometallic aluminum compounds are used to obtain the dopant; silica is obtained from organometallic silicon compounds or silicon tetrachloride.

Abstract: The invention is concerned with the design of processing stations for the processing, by welding technology, of semi-finished vehicle body subassemblies (5) within the framework of a flexible manufacturing system. Thereby, frame-like work piece carriers (1) with support members (4) are used for loose positioning of components of the subassemblies (5), where the work piece carriers (1) are also capable of accepting differently configured subassemblies. The transfer line (9) is not planned as a single line, but includes only the input station (10), the work position (6) and the output station (11). Next to these stations (10, 11), storage stations (14) are arrayed, which are connected with one another by a transport system (20) which crosses the transfer line (9). In this manner it is made possible to store the work piece carriers (1) with the processed subassemblies (5) or to bypass the next work station if it is not capable of receiving (a work piece carrier), or is out of order.

Abstract: A drying apparatus for sheets of sliced veneer has two conveyor belts lying one above the other running together jointly around a partially curvilinear, looped path guided by a plurality of guide apparatuses, the belts being positioned so that the sheets may be inserted between the belts for transport in a direction transverse to their widths, wherein the conveyor belts run rectilinearly between at least two of the adjacent guide apparatuses for a distance at least equal to half the maximum width of the sheets fed between the belts. The guide apparatuses may be rotatable cylindrical structures, for example rollers or cylinders, whose axes of rotation preferably all lie in the same horizontal plane. These rotatable cylindrical structures may be provided with brakes, drying and heating units as well. Furthermore the drying apparatus provides a velocity difference between the belts of from 2% to 5% and the belts passing between adjacent pairs of rollers are inclined at angles from 30.degree. to 75.degree..

Abstract: The process for operation of a spinning or twisting machine calls for a plurality of working units which are concentrated in groups with at least one motor and tangential belt. The spinning or twisting machine has a different total power need based on different total numbers of working units and/or use of working units with different individual power needs. Independently of the total power need of the spinning or twisting machine, all the motors have the same dimensions. The number of motors are selected so that the sum of the nominal power output of the motors at least approximately corresponds to the total power need of the spinning or twisting machine. Each of the motors are associated with a number of the working units such that the sum of the individual power need of the working units corresponds at least approximately to the nominal power of the motor.
