In a method and device for filtering a suspension of particles in a liquid the liquid is passed continuously through a porous membrane, particles from the suspenion gradually accumulating on the membrane and clogging its pores. The filtered liquid is caused to flow momentarily in the reverse direction to return the accumulated particles to the suspension and so unclog the membrane. To achieve this...

Continuous glass fiber reinforced composites are made by pultruding the fibers with mixtures of certain silanes and thermoplastic resin in which the silanes have adsorbed onto the thermoplastic resin.

A cooling liquid is injected (7) into and supplied to a cooling tubular body (1) along its inner periphery to form a cooling liquid layer (21) flowing down the inner peripheral surface of the body while revolving. A molten metal is then injected (15) into the cooling liquid layer from the inner peripheral side thereof to divide, rapidly cool and solidify the stream of molten metal with the cooling...

A device for deactivating price tags of the kind provided with a magnetic strip intended to form part of an anti-theft store security system, said device being intended for use together with a so-called scanner used to optically read a bar code on an item of goods . The invention is characterized in that the deactivator (2) includes two or more mutually adjacent and mutually parallel rows (4, 5) o...

An information recording and reproducing device uses a recording medium which is provided with units composed of blocks and a unit information recording area containing: unit allocation information; sector number information indicating the number of sectors per unit; and unit number information identifying each unit. When the recording medium is placed in the device, the respective information is ...

An improved bio-osmotic fluid for filling implant lumens consisting substantially of an amount of a bio-compatible organ- ic polymer and a solution of bio-compatible salt is disclosed which exhibits osmotic qualities closely paralleling that of human body serum and improved radiolucency with respect to silicone oil and saline . The present bio-osmotic fluid can be used in plas- tic and reconstruct...

Responsive to an addressed command from the hea...

2078562 9115062 PCTABS00007 A cable television radio frequency data processor (322) for receiving and processing data transmitted from a cable television terminal (315) to the headend (312) of a cable television system comprises a plurality of data receivers (810-813) for receiving the returned data, detectors associated with each receiver for providing an indication of received signal strength an...

2078563 9115065 PCTABS00007 A method of transferring a data message from a remote unit (120) to a central location (110) is provided. A plurality of data channels is selected for transmitting the data message from the remote unit (120) to the central (110) location. At least one random transmit time is generated for transmitting the data message for each of the plurality of data channels. The data...

The present invention provides a cryogenic storage container having a pressure vessel surrounded by a vacuum vessel for maintaining a vacuum between the outer wall of the vacuum vessel and the pressure vessel. A pair of intermediate and sub-intermediate heat shields are disposed between the outer wall of the vacuum vessel and the pressure vessel for intercepting the heat that would otherwise be tr...

1. A wheelbarraw comprising a frame having two arms (1) defining handles, supporting legs (2), a load container (10) and a support structure (3) maintaining the center of gravity of the container (10) in working position substantially in vertical alignment with the axle (6) of the wheels (8) and comprising at its forward end an abutment member (5) extending to each side of a longitudinal center pl...

The present invention provides a modified chimeric monoclonal antibody comprising wo molecules of each of two differ- ent polypeptides. The shorter polypeptides function as the light chains of t he antibody and the longer polypeptides function as the heavy chains of the antibody. Moreover; the polypeptide which functions as a heavy chain has a variable region characteristic of a first mammal and a...

The apparatus has a supporting frame defined by four uprights (2) bearing a pair of horizontal parallel beams (3) interconnected by cross members (4) having guides (5). A gearmotor-driven carriage (6) is movable horizontally along the guides (5) in a first direction. The carriage (6) bears rods (8) extending parallel to the guides (5). A gearmotor-driven trolley (14) is movable along the rods (8) ...
