Abstract: A filtering device in which two or more chambers are each provided with an inlet 23, 26, 29, 32, an outlet 25, 28, 31, 34 and a device 2, 27, 30, 33 for removal of filtration retentate. It is desired that the filtering device is suitable for the separation of liquid part- components in a liquid mixture. This is achieved by using the filtering device for separation of the liquid mixture into at least two liquid part-components and an aqueous component, if, during supply of the liquid mixture through the inlet 26 of the first chamber, its filter medium 12 is suitable for the retention of the liquid part- component of largest molecular size, and the device for the removal of the filtration retentate is a pipe 27 for this liquid part-component, and if for the transfer of the filtrate from the first chamber to the second chamber, the outlet 28 of the first chamber is joined to the inlet 29 of the second chamber, the filter medium 13 of which is suitable for the retention of the liquid part-component of largest molecular size contained in the filtrate supplied, and the device for the removal of the filtration retentate of the second chamber is a pipe 30 for this liquid part-component. Due to this arrangement, chamber filter presses or rotary filter presses known per se can be very easily modified for filtering out liquid part-components. <IMAGE>

Title: Valve controlled flow into a tube
Inventor: SAMSON ILAN ZADIK
IPC: A61B5/288
Filed: 1996-06-07
Granted: 2001-08-09
Abstract: Vacuum in a non-invasive medical probe having a source of vacuum interconnected with a suction cup by a resilient walled tube, is reduced in a controlled manner by creating a valve aperture in the wall of the tube at a desired location through which aperture no appreciable leakage will occur when vacuum is applied and the tube is in a relaxed state, whereby with the suction cup secured by vacuum on a patient's skin, application of a force to the tube wall will open the aperture and permit a controlled reduction of vacuum in the suction cup to a specified amount. Releasing the force permits the aperture to close so that lower vacuum is maintained and the suction cup continues to be secured on the patient's skin. In a preferred application there is provided a probe adapted for application to the scalp of a fetus with the rim of the suction cup in sealing contact with the surface of the scalp. There is also provided a method of enabling a controlled flow into a resilient walled tube inside which the pressure is lower than outside the tube, by creating a valve aperture in the wall of the tube in a desired location through which no appreciable leakage will occur when the tube is in a relaxed state. The aperture opens on application of a force to the tube wall and permits a controlled flow therethrough into the tube, and the aperture closes when the force is released.

Title: Monoport airgun for seismic exploration having discharge port extending continuously for 360° around its axis
Inventor: MAYZES EDWARD WILLIAM
IPC: G01V1/137
Filed: 1991-11-13
Granted: 1997-04-01
Abstract: A monoport airgun for seismic exploration has a single discharge  port  extending  continuously  for  360°  around  its longitudinal axis.  This airgun has a first housing providing a firing chamber containing pressurized gaseous fluid (gas) and a second housing providing an operating chamber.  The first and second  housings  are  positioned  in  alignment  along  the longitudinal axis.  They are spaced apart along this axis for defining the discharge port between them extending continuously around the axis.  The two housings of the monoport airgun are interconnected solely by a guide member concentric with the axis.          A shuttle encircling the guide member is movable therealong between closed and open positions.   In closed position,  the shuttle closes the firing chamber for retaining pressurized gas therein.  In open position, the shuttle opens the firing chamber to the discharge port for allowing pressurized gas to blast from the firing chamber through the discharge port.  The discharge port which extends continuously around the axis flares outwardly in generally exponential horn-like configuration for enhancing effectiveness of the discharge port in generating seismic energy waves.  A passageway in the guide member supplies pressurized gas from the operating chamber to the firing chamber when the shuttle is in closed position.  This passageway is blocked by the shuttle in open position.

Abstract: A disk screen or like shaft structure is disclosed in which screen disks (14), surround disks (24), and spacers (28) are con-nected together in modular relation. The surround disks (24) have metallic flanges (25) which shield the plastic spacers (28) which are located on either side of the surround disks (24) between the screen disks (14). The spacers (28) are formed of resilient plastic to allow the disks to deflect from their radial plane and the flanges (25) of the surround disks (24) are sufficiently smaller then the spacers (28) to avoid contact with the screen disks (14) in their deflected positions. The assembly is placed under a predetermined endwise compression and the module is mounted on a rectangular shaft (27) which is suitably supported for rotation. The assem-bly is particularly suited for screening of wood chips in the paper making industry where exposed plastic parts is undesirable.

Title: Thin material handling system for use in downcoilers and the like
Inventor: MONACO GAETANO
IPC: B21C47/34
Filed: 1990-12-20
Granted: 1997-02-25
Abstract: A method and apparatus for manipulating hot metallic material includes placing a coil of the material at a first position, the coil having an open coil eye, and initiating uncoiling of the coil while it is in the first position.  During uncoiling, the coil is transferred to a second position by moving it in a direction transverse to its axis, and heat loss from the coil side edges is restricted by providing heat shield means closely adjacent to the side edges.  The uncoiling continues at the second position, and when the coil is near the end of the uncoiling operation at the second position, a coil opener pin is inserted axially into the open coil eye without contacting the coil, thus avoiding conductive heat loss to the pin.  Finally, at the completion of the uncoiling operation, the last few coil wraps are pulled into contact with the pin as the coil is pulled downstream out of the second position, whereby the pin prevents collapsing or crushing of the final portion of the coil.  An optional holdback roll located downstream of the second position is such as to come in contact with the final wraps of the coil as the latter is pulled downstream out of the second position, and the pin is positioned so as to enter the open eye of the coil whether or not the coil has moved from the second position.

Title: Branched polyanhydrides
Inventor: DOMB ABRAHAM J
IPC: C08F20/02
Filed: 1991-06-04
Granted: 2002-09-24
Abstract: Branched polyanhydrides that have superior pro-perties for use in the controlled delivery of substances, prepared by the polymerization of a dicarboxylic acid monomer and a branching agent. The branching agent is a polycarboxylic acid monomer such as 1,3,5-benzen-etricarboxylic acid ("BTC"), or an oligomerized fatty acid trimer. Alternatively, the branching agent is a poly-carboxylic acid polymer such as poly(acrylic acid) ("PAA"). These branched polymers have significantly higher molecular weights and lower specific viscosity than linear polymers prepared under similar conditions.    A major advantage of branched polyanhydrides is that the degradation and release kinetics can be substantial-ly altered without significantly changing the physical properties of the polymer relative to the corresponding linear polymer. By manipulating both the diacid and the branching agent, a wide variety of biodegradable controlled delivery devices for diverse applications can be prepared.
