A container for the continuous centrifugal separation of platelets component in blood, having a first and a second closed chambers adaptable to be rotated around a rotation axis. Whole blood is continuously introduced into the first chamber. Platelet-rich plasma being obtained as supernatant in the first chamber being discharged through a first outlet port opened at a relatively short distance fro...

The invention relates to a process for centrifugal separation and to an apparatus for carrying it out, applicable to a mixture of phases of any states, said apparatus comprising, disposed coaxially and moved in rotation in a fixed enclosure, a fan adapted to create a depression upstream, a rotary distributor converting the pressure drop resulting from the action of the fan on the upstream pressure...

A process and apparatus for the manufacture of plates of an electrical storage battery involves the partial or total severing of a plate blank from a strip of stock material and the subsequent filling of a grid of the plate blank with a material in paste form prior to the removal of the filled plate from the stock material.

A process wherein the workpiece is prewarmed and the prewarmed workpiece surface to be polished is moved past a CO2 laser and thereby briefly irradiated.

A method and apparatus for applying paste to battery grids wherein the paste is circulated in a primary circuit incorporating an open reservoir wherein the paste is relieved of all pumping pressure and portion of the paste is diverted from the primary circuit into a secondary circuit for delivery to a nozzle which may be selectively opened and closed to deliver paste to the grid, the secondary cir...

PURPOSE:To easily generate a dummy fault, by reporting an input status word of an operation panel to a host device, when an input/output instruction designated by the panel coincides with an input/output instruction whose execution has ended, and also the number of instructions has exceeded the number designated from the host device. CONSTITUTION:A magnetic tape controller 2 which has received an ...

A relatively long fiber reinforced polyurethane article formed by forming relatively long fibers into a composite, binding said fibers to each other to set or fix the composite, filling said composite with a urethane precursor and reacting to form a long fiber reinforced polyurethane article.

A composition comprises an isocyanate-terminated prepolymer having a viscosity of from 5,000 to 50,000 centipoises, a catalyst, and an unhalogenated hydrocarbon propellant whose boiling point or initial boiling point is not greater than 10 DEG C at atmospheric pressure. A one- component moisture-cure polyurethane foam can be prepared by dispensing such a composition from a pressurised container.

Hospital mattresses are generally made of foam plastic having predominantly open cell cores and are in the form of a parallel-epipedic block (1) which is provided with a protective layer (12 and 13) consisting of a plastic film which is easy to clean so that injurious substances and bacteria can be removed. Such mattresses have the drawback, however, that when used they produce sounds which are di...

A security device for use on bicycles, comprising two substantially hook shaped members which are each adapted to be hooked around respective ones of the wheel forks of a wheel of the bicycle. A connecting rod extends between the said wheel forks, through the wheel spokes, and connects the said hook shaped members together, and at least one of the said hook shaped members is slidable relative to t...
