There is now provided a tool for chipforming machining of metals and similar materials comprising a high speed steel core and a cover of more wear resistant material than the core. If the material in the core has a carbon content 0.05-0.25% lower than the conventional carbon content for the high speed steel in question, improved properties can be obtained.

A hydraulic control system of the present invention is provided for improving a responsiveness to a speed change by compleating the speed chang with a torque pressure control hydraulic pressure after initiating the speed change with the drive hydraulic pressure. The hydraulic control system includes an oil pump for generating hydraulic pressure, a pressure regulating valve for regulating the hydra...

Dense star polymers or dendrimers, modified by capping with a hydrophobic group capable of providing a hydrophobic outer shell, act as molecular nucleating agents in forming a polymer blend.

A method of determining a crossover reel's diameter while being produced and driven by a friction roller entails measuring the angular velocity of the reel (11) by a transmitter associated with a part rotating with the reel and processing the velocity. The reel diameter is calculated by dividing the circumferential velocity of the reel surface by the angular velocity, the circumferential velocity ...

The invention concerns a method of automatically producing lead storage batteries, preferably in an on-line operation. According to the invention, substantially grid-shaped lead electrodes are produced which are provided with a pasty active mass and then immediately with a separating material on both sides. The electrodes are then stacked, electrically connected, inserted into a housing so as to f...

A novel vent pin (1) releases air from moulds during ejection and/or vulcanisation of rubber items, especially tyres. This takes the form of a hollow (5) pin, one end (8) closed, the other (6) open. The closed end has small passages, especially 0.12 mm wide at most, forming de-aeration gaps. Also claimed are the method of construction, essentially as described; and a vulcanising mould, especiall...

A process for applying several coats of paint to an electrically conductive substrate, by applying (1) an electrophoretic primer coat, stoving the primer, directly applying (2) a coloured and/or special-effect coat and then applying (3) further overcoats as required. Coating composition (2) comprises an aqueous coating material containing pigments and a binder consisting of (A) 50-85 wt% hybrid bi...

A slow scanning CT Scanner providing slice data simultaneously for a plurality of slices so as to avoid blurring between adjacent slices due to patient movement.

A blood filtration device (16) encapsulates a filter pad assembly (20) within a flexible housing (18). The filter pad assembly (20) includes first and second filter media layers (44, 46). A first heat and pressure sealed region (28) integrally bonds the peripheries of the first and second media layers (44, 46) together. The flexible housing (18) comprises a peripheral rim (34) aligned with the fir...

This invention is directed to a method and system for extracting a solute from a fluid or a dense gas using a porous membrane. The invention includes providing a porous membrane having opposite sides in a module under pressure, with the membrane serving as a barrier interface between a fluid and a dense gas. The dense gas is introduced into the module on one side of the membrane and the fluid is i...

A method and system for treating aneurysms by applying RF energy to collagen. A catheter is disposed near the aneurysm and collagen is exuded into or near the aneurysm. RF energy is applied, using the same catheter or a second catheter, to the collagen, causing the collagen to harden and cover the weak region of the blood vessel wall, and providing a base onto which epithelial cells of the blood v...

A pneumatic tire comprising an air permeation prevention layer adapted to substantially cover an interior surface of a carcass layer by winding a slit film made of a resin film made mainly of thermoplastic resin around an inner circumferential surface of the tire in a spiral fashion and a method for manufacturing a pneumatic tire comprising the steps of winding the slit film around an outer circum...

The invention relates to a method for resetting a processor, and a watchdog for generating a reset pulse to a processor which can initialize itself and which sends acknowledgement pulses at predetermined intervals to the watchdog comprising transmission means (5) for generating and transmitting reset pulses to the processor. The watchdog comprises counter means (7) for counting the number of reset...
