Abstract: A method of increasing the time-averaged cross-flow fiftra- tion flux of a liquid through a porous filter medium over the period of a filtration run, comprising the steps of (a) flowing the liquid transversely through the filter medium by establishing a pressure differential across the filter medium and (b) commencing the filtration run by gradually increasing the flow rate of the filtrate from essentially zero to the desired operational flow rate over a sufficiently extended period of time to substantially prevent the intrusion of the particles of material being filtered out of the liquid into the filter medium per se. 
     Also disclosed is an apparatus for practising the above method.

Abstract: In an electrical motor having a tachometer generator arranged to product an output signal indicative of the rotational speed of the motor by detecting the movement of magnets or magnetized portions, convex and concave portions (13a, 13b) are successively and alternately formed in a rotor magnet (13). Awave-like conductor pattern (11 a) is arranged to oppose the convex and concave portions (13a, 13b) to induce a voltage when the rotor magnet (13) rotates. The convex and concave portions (13a, 13b) in each of N and S poles alternately arranged circumferentially have a phase which is shifted by a half cycle in circumferential direction from the phase of adjacent poles. In one embodiment, a radial groove (14) is made in the rotor magnet (13) while a corresponding conductor pattern (11 b) is provided to oppose the groove (14) so as to detect origin of rotation. The rotor magnet may be flat or cylindrical. In the case of using a cylindrical rotor magnet, the wave-like conductor pattern (106a) is made on a flexible printed circuit board (106) which is cylindrically curved.

Abstract: @ The present invention pertains, in a particularly preferred embodiment, to an apertured, macroscopically expanded, resilient three-dimensional polymeric web which is believed to have particular utility as a breatheable barrier for a disposable bandage such as a diaper. The web preferably comprises a deeply drawn three-dimensional structure containing a multiplicity of debossments of macroscopic (i.e., visibly perceivable by the normal human eye at a perpendicular distance of about one foot) cross-section, each of said debossments originating as an aperture in a first surface of the web and having a continuously interconnected side wall extending in the direction of a second, remotely located parallel surface of the web. The side wall of each debossment terminates to form an end wall in the second surface of the web. The end wall includes a multiplicity of apertures, each of said apertures being sized and shaped to independently support an aqueous fluid meniscus. The smaller apertures in each end wall are so spaced relative to all adjacent apertures in the end wall that the aqueous fluid menisci supported in the apertures do not contact one another or the side wall. In a disposable absorbent bandage context, the second surface of the web containing the end walls with small apertures therein is placed in contact with the absorbent core portion of the bandage and the surface of the web in which the debossments originate is oriented so as to contact the wearer's outer garments in use.

Abstract: For the non-deforming treatment of moving sheet material, e.g. for squeezing out the rolling emulsion in cold strip rolling mills, opposing, axially adjustable rollers 1, 2 are used as squeeze rollers which are slightly S shaped or bottle-like over the entire surface length so that the contours of two rollers located on both sides of the roller gap complement one another only when these rollers are in a specific relative axial position. In other axial positions the roller gap becomes narrower either in the middle or at the ends of the roll surface so that, through axial adjustment of the rollers irrespective of the deflection of the rollers and/or deviations in the plane- parallelity of the surfaces of the strip B, an even squeezing effect or other even non-deforming treatment of the product can be achieved over the entire strip width. Moisture sensors 51 - 54 can also be provided between successive contoured pairs of rollers 1, 2 and 1', 2', the axial displacement of the second pair of rollers 1', 2' being controlled according to the signals from these in order to remove any remaining area of moisture 50.

Abstract: A head positioning system particularly intended for a magnetic disk storage system has a magnetic recording medium (3) with a periodic arrangement of a data tracks (6) and a servo tracks (4, 5) with a track pitch P, a multi-head (1) carrying a plurality of head elements (H1-Hn) arranged in a direction perpendicular to the tracks. The length or spacing between the head elements and that of the tracks is similar to that of a sliding vernier caliper, so that only a small relative transverse movement is required to bring one of the heads into alignment with a particular track. In one embodiment, the spacing of the heads is (N<sub>h</sub>+1/M)P where N<sub>h</sub> and M are integers. One of the head elements (H1-Hn) is selected as a multi-head (1) moves transversely to the tracks so that the selected head is just on a servo track. The head element (H1-Hn) to form a data head for writing and/or reading data on and from the tracks is determined in accordance with the selected servo head. Thus, since a servo signal is continuously obtained from one of the head elements (H1-Hn) an accurate and quick head positioning is achieved.

Abstract: Apparatus for conditioning stratified water bodies having epilimnion (12), metalimnion (14) and hypolimnion (16) layers has a reservoir (22) for containing water so as to define a gas-liquid interface, at least one upwelling conduit (24) adapted for generally vertical disposition within the water body and having an upper discharge end (22) fluidly connected to the reservoir and a plurality of intake ports (46-58) longitudinally spaced along the conduit so as to afford fluid communication with predetermined depth levels of the water body, and a return conduit (26) adapted for generally vertical disposition within the water body and having an upper inlet end (44) fluidly connected to the reservoir (22) and a plurality of discharge ports (62-74) longitudinally spaced along the return conduit so as to afford fluid communication with predetermined depth levels of the water body. Flow controllers (60,76) are provided for selectively alternately opening and closing off the intake and discharge ports, and pumps (28) are operable to move water from the water body through the open intake ports (46-58), through the upwelling conduit (24) to the reservoir (22), through the return conduit (26) and out the open discharge ports (62-74) of the return conduit. Thus it is possible to alter the thermal/density structure and oxygen content of a body of water having epilimnion, metalimnion   and hypolimnion layers by forming at least one new induced isotherm at a selected depth within the layers by controllably injecting the drawn water from the return conduit (26) into the water body at the selected depth to form a barrier to upward diffusive transport of nutrients.

Abstract: In order to supply a d.c. bias to the drain electrodes of MESFETS (1-4) in a distributed amplifier operating in the 500MHz to 20GHz or above, a d.c. source (15) is connected to the drain line (5,9,11,14) via a feed component (16) which comprises a ferrite bead (17) having an axial aperture (18). A coil (19) comprising, for example, four turns of 20 micron gold wire is wound on the bead in toroidal fashion. The bead may be of the kind which is used for low-frequency interference suppression or for encircling the emitter lead-out wire of a bipolar transistor operating in the lower megahertz range. At these relatively low frequencies in the conventional use of the bead, the bead material will exhibit low magnetic losses and high permeability. However, in the present invention, due to the microwave signal in the coil, the bead operates over a frequency band which is many times higher than its normal operating band. At these high frequencies the bead material exhibits quite large losses. The feed component acts, as far as the microwave signal is concerned, as though it is a relatively large resistor, which isolates the low impedance of the d.c. source from the microwave signal path in the drain line. As far as the bias supply is concerned, the d.c. resistance of the coil is negligible, so that there is virtually no d.c. power dissipated in the feed component. The feed component can be used for other applications where a high resistance at microwave frequencies is required, together with substantially zero d.c. resistance.

Abstract: The cartridge comprises a shutter for closing the openings (18) for access to the disk on the two faces thereof. The shutter is formed by a hollow bar (24) carrying two closure plates (21) and slidable in both directions along a guide (26) adjacent to an edge 19 of the cartridge. A tension spring (28) which passes through the hollow bar 24 is connected to two blocks 30 which are slidable in the guide (26) and which are arranged to be entrained by the bar (24). The trailing block cannot follow the bar because a tongue (31) on the block abuts the end of an elongated lug (32) extending along the central part of the guide (26). 
     The reading device comprises a case for receiving the cartridge and a lever which is rotated when the cartridge is inserted and carries an element for pushing the shutter aside. The lever 53 is controlled by a cam slot carried by a slide member which is manually actuable to provide for expulsion of the cartridge.
