The centrifuge has an electric motor (18) of the squirrel cage type for the rotation of the centrifuge drum (2) during centrifugation and an electric control (20) comprising a frequency converter (21) for the control of the RPM of the electric motor (18). When cleaning the drum (2) a frequency converter (21) is coupled into the normal current supply line (25) to the electric motor (18) by means of...

A breathable laminate comprises at least two porous webs laminated together with a porous adhesive matrix, preferably a random fibrous adhesive pattern having a coat weight of between 1.5 and 12 grams per square meter. The two or more porous webs comprise woven or non-woven materials and the resulting breathable fabric or laminate has good hand and flexibility. Breathable fabric is adhered to foam...

The method of operating a microprocessor with pipelined architecture allows instruction data for a later instruction execution cycle to be fetched from memory during a current instruction cycle. The method requires; preprogamming instruction operation codes for instructions which require more than one byte of instruction date with additional information requesting time-compressed fetching of instr...

A pressure sensor (1) has a housing (6), a plate (2) having a diaphragm region (3), and an intermediate support (4) on which the plate (2) is mounted and which is joined to the housing (6) by means of an adhesive (5). Despite its simple construction, it is desirable to be able to use such a pressure sensor with large static and pulsating pressure loads. For that purpose the adhesive (5), which may...

A method of allocating radio channels, between the base stations of a multi-base station radio system, uses a mathematical model of the radio system which is derived from an analog of the radio system. The analog is a thermal bath containing a plurality of interacting particles, each particle in a particular spin state. The number of particles at a given location in the thermal bath, corresponding...

A method of controlling scar formation in humans by applying a force to tissue in an amount to create a wound; applying a lathyrogenic agent to the wound; forming the wound into a predetermined stationary or movable beneficial configuration; and maintaining the wound in the predetermined configuration and in contact with lathyrogenic agent during healing.

31,778-00 TRANSANAL ANASTOMOSIS RING INSERTION DEVICE A transanal insertion device for surgically inserting an anastomosis ring having two unitary members into a tubular anatomic member comprises a distal adapter, a proximal adapter and an actuator. The distal adapter includes a hollow distal sleeve and a spring-loaded distal spool axially movable within the distal sleeve. The distal spool is bias...

This invention reduces the fine thermal cracking catalyst wastes in settled petroleum by mixing the settled petroleum (DCO) containing small parts of thermal cracking catalyst with waste products from the distillation of petroleum and then treating the DCO-resin mixture with a non-aromatic hydrocarbon solvent in an extraction unit.

The process for manufacturing a polarizing film based on polyvinyl alcohol and at least one dichroic substance by casting or extrusion of a mixture of polyvinyl alcohol and a solvent, whereby the polyvinyl alcohol contains the dichroic substance, drying and stretching of the film by between 300 and 1200%, whereby, depending on the width of the unstretched film bo, a stretch gap lo is provided, sat...

The closure device comprises four coplanar wedge-shaped plates 24, 26, 28, 30 which are confined and can slide within a square frame 22 surrounding the mould inlet passage 12, 14 so as to form a square aperture surrounding the said passage. The plates are each wedged behind the next plate and two alternate such plates 24, 30 can be moved in the direction of advance of the wedge through the action ...

The apparatus comprises: a plurality of preliminary stations (S1...S4) dedicated in succession to identification of the type of vehicle, battery removal and elimination of liquid residues; a successive central station (SC) for heat treatment provided with: controlled-temperature burner means (BR) for burning residual non-metallic materials; mechanical means for eliminating ash; and aspiration mean...

A pressure control valve of the type having pump, tank and load-sensing connections used in conjunction with one or more proportional type valves. In this type of system a load-sensing signal is tapped off from the output side of the proportional valves and conveyed to the load-sensing connection of the pressure control valve. A pressure control valve of the type herein has load-sensing and pressu...

Means for positioning pipes for drainage systems, with a substantially vertical support 15 for sleeve means 14 which can be moved and positioned longitudinally, with an incorporated substantially horizontal bar 13 with at least one length of pipe 12, of which at least one 12 is fixed to said bar 13, said pipe lengths 12 being substantially horizontal and substantially normal to said bar 13.

A safer system of payment by means of prepaid magnetic cards provides for permanently and physically limiting by punching a hole (A) through the card the magnetic track wherein a spendable amount is recorded upon the issuing of a new card. The spendable sum is recorded automatically on said track by the issuing machine and the length of the recorded string (B) is proportional to the sum. The limit...
