Abstract: Into a material based on a caoutchouc-type or caoutchouc-containing mixture for producing hard rubber, there is incorporated a pre-mix containing high-strength organic fibers and a liquid hardenable plastic material. The high-strength and temperature resistant material thus obtained is particularly suitable for the attenuation of noise in combustion engines when heavy-weight fillers are also added to such material. Engine components like, for example, valve covers, timing gear covers and oil pans can be manufactured from this material.

Abstract: The antistatic desk pad for a working station in the electronic field is comprised of a rubber sheet with a resistance of at least 10.sup.2 .OMEGA. cm. The upper portion of the sheet is provided with cavities of which the length is at least 8 mm, those cavities being intended to receive the debris of wires or the like.

Abstract: A glove formed of rubber or plastics material, especially an examination or surgical glove devoid of a roll-down preventing beaded edge and containing a structured surface at the cuff region. The structured surface is formed at the outer side or surface of the glove by non-connected raised portions, whereas the structured surface is formed at the inside or inner surface of the glove by mirror-image, non-connected recesses or depressions. The mold for fabricating the glove contains non-connected recesses at the cuff region.

Abstract: A level crossing for a railroad and a method of fabricating the same comprising outer plates arranged between the rails and the body of the roadway, the outer plates being supported at one side at the rails and at the other side at a profiled constructed closure provided for the roadway body. The positive supporting of the outer plates at the profiled constructed closure is achieved through the agency of elastic molded bodies formed of rubber, plastic or the like.

Abstract: A capacitor comprising at least two electrodes separated from one another by an elastic dielectric formed of rubber and/or plastic for measuring forces acting upon one of the electrodes--the so-called measuring electrodes--by detecting the resultant change in capacitance. The dielectric in its unloaded state is pre-compressed and preferably possesses a number of hollow spaces.

Abstract: An optical system focuses a laser beam emanating from a laser onto a surface of an object, such as a circumferential surface of the object to be measured. The light beam is reflected from the object, so as to form a generally focused light spot; the intensity of the light spot, which depends on the distance of the surface from the optical system, is measured, and the measurement results are displayed and/or utilized for controlling the dimensions of the object, if the object is an elongated article, and is continuously produced, generally in a direction transverse to its cross-section.

Abstract: A tread for a pneumatic tire comprising two inner ribs extending in the circumferential direction of the tire and, to both sides thereof, tiers or block rows extending in the circumferential direction of the tire. The block rows and ribs are each separated from one another by a respective zig-zag configured circumferential groove. Each leg of the intermediate circumferential groove encloses, with the circumferential direction of the tire, an angle .alpha. of approximately 30.degree. to 50.degree., whereas the legs of the lateral circumferential grooves enclose, with the circumferential direction of the tire, an angle .beta. of approximately 55.degree. to 65.degree. and the lateral circumferential grooves are each wider than the intermediate circumferential groove.

Abstract: An apparatus for the bellowless or bagless vulcanization of tire blanks comprising a tire vulcanization mold and a clamping mechanism for the tire bead provided for the mold. The clamping mechanism comprises the associated bead section of the vulcanization mold and a contact mechanism which can be moved towards such section in the axial direction and against the center of the mold. The contact mechanism comprises a ring formed of a number of segments, and such ring is provided at least at the region of the tire bead with a continuous layer of elastomeric material. According to a further improvement, the continuous layer possesses a lip member directed towards the tire bead.

Abstract: A windsurfer comprising a board-like floating body and a sail connected therewith by means of a mast or pole. The floating body, viewed in cross-section, comprises a number of adjacent hoses communicating with one another, and a rigid plate is arranged between both of the outer hoses.

Abstract: A windshield for vehicles, especially inflatable boats or the like, comprising a rigid frame, the lower leg of which is provided at its outer side or surface with a longitudinal groove possessing undercut portions and serving to receive a complementary structural member, typically a profile member, secured to the vehicle chassis, especially the body or hull of the boat or otherwise.

Abstract: A package for a pair of sterilized gloves used for medical purposes and a method of forming such package, wherein the upper and lower ends of a sheet are folded at right angles to the lengthwise direction of the inserted gloves for covering the tips and the cuffs of such gloves. Then two lateral folds are formed substantially parallel to the lengthwise direction of the gloves at both sides of the same, there is then formed a fold at the central region of the sheet perpendicular to the lengthwise direction of the gloves, and then a fold centrally and parallel to the lengthwise direction of the gloves.

Abstract: The present invention relates to a pneumatic tire blank adapted to be vulcanized in a vulcanizing device of the kind not employing a bellows arrangement, but having a clamping system which acts upon the interior of the bead.

Abstract: A device for the continuous production of a strand of foamed material comprising a vessel to which a foamable reactant material is continuously supplied and from which said material continuously issues over a weir whose height is adjustable. The material passing over said weir becomes supported on a foaming track whose constituent parts are adjustable as regards length and inclination to suit the foaming characteristics of said material. Said foaming track is adjustable also relative to said weir so as to be kept close thereto and is also adjustable relative to a curing track.

Abstract: An apparatus for cutting conveyed materials, preferably webs or strand-shaped articles formed of reinforced or non-reinforced rubber by means of a rotating, oscillating or stationary knife or cutter, wherein the apparatus comprises a cutter car or carriage and a drive motor with a crank. The cutter is mounted upon a balance or rocker constructed as a lever. The balance is actuatable by means of the crank and the cutter describes a closed kinematic path of travel.

Abstract: A tire blank for a vehicle tire provided at its bead region or surface with a pre-vulcanized ply or a ply formed of a harder rubber mixture than the rubber mixture generally employed at the bead region. Each bead region of the tire blank possesses one such ply at its inner surface, and both plies are arranged at a spacing from one another.

Abstract: An apparatus for the butt connection of plies formed of plastic deformable material and having cut surfaces, comprising at least one contact beam which can be displaced at an inclination against the plies, this contact beam having a play contact surface for applying an inclined directed force to the plies which are to be butt connected.

Abstract: A method of fabricating molded articles composed of elastomeric material having embedded therein essentially oriented fibers, comprising the steps of fabricating a molded article with oriented fibers therein, positioning the molded article within a mold having two portions, a first mold portion defining the shape of the final molded article and a second mold portion arranged separately of said first mold portion and in communication therewith, said molded article being positioned partly in said first mold portion and partly in said second mold portion, subjecting the part of the molded article positioned in said second mold portion to a directed flow operation into said first mold portion and reorienting by said directed flow operation the fibers subjected to flow into a second fiber orientation direction differing from the fiber orientation direction of the part of said molded article positioned in said first mold portion.
