Cages of large bearings are normally made of plate-steel or brass. Due to relativelly high speed excessive wear, noise and surface defects develop between the cage (7) and rolling bodies (1). The claimed design obviates these known disadvantages by covering the contact area (11) between cage-pockets and rolling bodies with a rubber layer (13) whereby the thickness of the layer should preferably be...

A double-acting electromagnetic linear motor (10) is proposed which has a small construction as well as a large dynamic range and high energy density with a wet configuration. The linear motor (10) has a pressure tube (21) having two magnetically non-conductive intermediate pieces (27, 28) between which a centre piece (29) is located which conducts magnetic flux. Two permanent magnets (35, 36) of ...

An electromechanical double-acting magnet (10) having an integrated movement measurement system (12) is proposed which is of small construction and manages with a low drive current while having a high dynamic range, in the case of a wet type of construction. The double-acting magnet (10) has an integral pressure tube (21), which comprises an armature tube (23), which support two coils (18, 19), an...

Medical plaster for treating wounds consists of an elastic material which exerts a pulling action on the wound. In a wound contact area (2), the plaster features a contact width that is narrower than the two end sections (3,4) of the plaster (1). The narrower contact width may be effected through at least one recess (6) in the plaster (1). ADVANTAGE - The plaster promotes a prim. wound healing pro...

The invention relates to a process for producing moulded articles by sintering crosslinked polyisocyanate polyaddition products with an average particle size of less than 0.25 mm in a mould at temperatures of 100 to 300@C and under a pressure of greater than 50 bar. The moulded articles produced according to the invention are thermally stable up to at least 150@C and possess a high hydrolysis resi...

A shrinkable polyester film for applying to bottles and other articles comprises not less than 50 mol% of ethylene terephthalate units and has a birefringence of from 0.040 to 0.150, a shrinkage of not less than 40% in one of the machine direction and the transverse direction and a shrinkage of not more than 20% in the other of the said directions after 5 min treatment in an air oven at 100 DEG C,...

The surgical instrument includes a flat wire (5) that accepts a spring wire (8), which forms the chord (8a) and determined displacement distance (7a to 7b) outside the guide sheath (7), and is led back in a hook shaped shaft. A pull exerted on the flexible shaft (4) at the patient end of the guide tube (2) tensions the chord (8a), so that it forms an enlarged arc. The guide sheath is partly guided...

A fibre cpd. material, with fibres and esp. carbon fibres embedded in a matrix, is formed by covering the fibres (10) with at least one shrouding layer (12) which, at the same time, forms the matrix (11) of the cpd. Where the fibre cpd. material is a shaped body, a core (15) is covered with the fibre-cladding layer (12) and fibres (10) with the cladding layer (12) formed while the core (15) is wou...

The card reader has a pair of actuator elements (2) mounted on either side of the inlet slot and these connect with levers (4) that are spring loaded. Movement of the levers about pivot points cause the slide element (3) to move to provide access. The space provided has sufficient clearance for the specific size of card intended to allow insertion. After entry of the card the levers return to encl...

A thin pipe connecting joint comprises: a joint body including retaining walls bent individually from the two end portions thereof, and an assembly hole extending through the axis thereof; and a pair of pipes including engagement walls formed at their end portions to be connected and adapted to be brought into abutment against each other, elastic seal ring members assembled on the individual back ...

The inspection system comprises a camera 404 for capturing real-time images of a PCB 408 mounted on an X-Y table 407. The images can be displayed on a computer screen, with the computer capable of controlling the X-Y position of the PCB and the focus or magnification of the camera. A defect is detected visually and recorded on the computer by pointing to its position on the screen 302, with the na...

An aqueous emulsion based on grafted polyolefin, process for obtaining it and its use in a finishing composition. This emulsion comprises a mixture formed by compounding at least one polyolefin and at least one saturated fatty acid and/or at least one unsaturated fatty acid unsubstituted by a hydroxyl group, at least one base, water in the quantity needed to obtain 10 to 50% of solids content and,...

The invention relates to foamable melt processible fluoropolymer resins containing boron nitride and one or more of a class of inorganic salts which significantly enhance foam nucleation (as evidenced by small foam cell size).

Fibrous magnesium oxysulfate particles having a length of 10 to 100 mu m and a thickness of less than 1 mu m are used as an antiblocking agent for plastic films, especially polyolefin resin films.

The composition comprises, by weight, 0.5 to 3 parts of mercaptobenzothiazole, 0.5 to 3 parts of tetramethylthiuram disulphide, 3 to 5 parts of zinc oxide, 1 to 3 parts of stearic acid, 1 to 4 parts of antioxidant and 1 to 5 parts of a vulcanising agent made up of 0 to 100% of sublimed sulphur, 0 to 75% of 4,4'-dithiomorpholine and 0 to 50% of benzothiazylsulphenemorpholide, the ratio of the latte...

A process is disclosed for producing beaded, expansible styrene polymers that contain: (a) polystyrene and/or styrene copolymer with at least 50 % by weight styrene incorporated by polymerization; (b) 0.001 to 0.2 % by weight, in relation to (a), of an organic tin compound; and (c) 2 to 10 % by weight, in relation to (a), of an aliphatic C3-C7-hydrocarbon and/or carbon dioxide as a blowing agent. ...

The rotational speed (1wM) of the engine, the torques (Mkv,Mkn) taken up by the clutch in initial (low) and final (high) transmission ratios, the transmission output torque (MGA) and the engine output torque (MM) are adjusted in stages (t1-t5) by electrical commands to hydraulic control valves.
