Manufacturing fabric which becomes tacky on heating (1 in fig.), in which a textile base (2) is coated with a point arrangement of tacky polymer particles (3), comprises: (i) using a silk-screen printing frame (4) to place, on a transfer support with a smooth regular surface, an underlayer (5) of polymers, in paste form or in suspension in a solvent, whose melting point is greater than the tempera...

A central computer controls all aspects of brochure distribution. The travel agent (Reisbureau) transmits requests brochures (G1) from the computer centre. The computer sends back an acknowledgement (G2) and any brief data. At the same time it obtains brochure data (G5) from the tour operator (Reisorganisator) and sends it (G3) to the distributor. The distributor acknowledges the order with delive...

Wear parts of machinery have embedded within them optically recognisable elements, exposure of which is an indication of the state of wear. Corresponding wear parts, as well as wearing plates which slide on top of each other each have at least one element for indicating a state of wear. In the non-wearing reverse side of the wearing plates are embedded elements of material of up to the hardren of ...

A bladder carrying apparatus for a tire vulcanizing press by which a bladder assembly can be carried readily and rapidly onto and off of a center mechanism is disclosed. The bladder carrying apparatus includes an arm mounted on a chuck of a loader, which is mounted for upward and downward movement and also for turning movement for seating a green tire onto a lower metal mold of the tire vulcanizin...

In a mammographic X-ray apparatus the breast (4) to be photographed is pressed between a press plate (2) and a film cassette (5) or an equivalent depicting member, and the compression force (F) applied to the breast (4) is measured by a detector (3). On the basls of this measurement, the velocity (V) of the compression movement of a press motor (7) is regulated. The apparatus comprises a C-arm (1)...

The present invention relates to a method and an apparatus for controlling a car equipped with an automatic transmission having a lockup clutch. According to the control method of the present invention, when the lockup clutch is in the lockup state, a variation of a generated torque is detected. When the range of the torque variation detected exceeds a predetermined value, an engine torque is redu...

The magnet forms a servo for hydraulic proportional valves. The actuating magnet (3) and the path retainers (10) are separate, functional units with a housing each, with the path retainer secured to one front side (11, 8) of the magnet. The energising electronic (30) is located in a plastics housing (7) with two mutually orthogonal support faces (9, 26). One support face abuts the front side (11) ...

This electromechanical treatment is for waste asbestos, and masses which contain it. It eliminates a potentially harmful material, at the same time producing a secondary raw material. In this original method, the raw material is size-reduced, dispersed, wetted and/or mixed, producing a non-magnetic multiphase which can be pumped. The method employs electromagnetic energy in the form of a field, wh...

The present invention comprises a process for the asymmetric synthesis of florfenicol, thiamphenicol or chloramphenicol, from a derivative of trans-cinnamic acid, comprising the steps: (a) converting the acid to an acid chloride using a chlorinating agent, and reducing the acid chloride to a trans allylic alcohol with a reducing agent; (b) asymmetrically epoxidizing the allylic alcohol of step (a)...

The invention concerns a method and equipment for mixing hard granules into tyre tread bodies and furthermore into sundry rubber strips and tread stock, whereby rubber stock (5) is extruded (2) into tread bands (6) of a suitable shape which are rolled under control, in a suitable thickness and number of layers, in a circular process over a pre-treated tyre (9, 17) or other material (object) which ...

The invention relates to films of linear polyester containing glass spheres having a certain particle size distribution and in a certain amount. The addition of the glass spheres improves, inter alia, the dynamic coefficient of friction of the film. Preferably, a second film additive, fumed silica, of a controlled particle size distribution and weight is added to the film. The addition of the fume...

Bead portions of a tire are supported during tire manufacture by a bead support assembly (100, 1100, 2100) having relatively movable parts that cooperate to define an elongate, outwardly opening groove (200, 1200, 2200) that receives and supports the bead portions (B). The relatively movable parts include a flexible cover (170, 1170, 2170) that overlies a relatively rigid underlying support (120, ...

A method of producing a spliceless annular tread cap (2), whereby a portion (23) of an extruded tube (21) of green elastomeric material is fed inside an annular body (8), the inner annular surface (17) of which presents a diameter approximately equal to but no smaller than the outside diameter of the tubular portion (23), and negatively reproduces the pattern of the finished tread cap (2); the tub...

The laying of lengths 40 of cord (yarn, wire) 4 is provided for by a laying hose 30 which receives the cord, with its inlet arranged opposite the outlet of a wire dispenser whose cutter 85 cuts the cord just upstream of the laying hose 30. A laying head 32 is arranged at the end of the laying hose 30, which head moves transversely along the support 1 onto which the reinforcement is built. The angl...
