Title: Vehicle transmission hill holder with releasable toothed clutch
Inventor: YANT KENNETH B
IPC: B60W30/18
Filed: 1993-10-04
Abstract: ABSTRACT OF THE DISCLOSURE    A hill holder cooperates with a countershaft in a vehicle transmission to permit rotational movement thereof in one direction while preventing rotational movement thereof in an opposite direction.  The hill holder includes a cylindrical housing which is supported on a rear wall of a bell housing of the transmission in co-axial relationship with the countershaft.  A clutch assembly is provided in the hill holder for selectively connecting the countershaft to the housing to prevent rotation thereof in one rotational direction.  The clutch assembly includes a hub member which is secured to the countershaft for rotation therewith.  The clutch assembly further includes a reaction member which is axially movable relative to the housing, but is restrained from rotating relative thereto.  Mating ramp-shaped teeth are formed on adjacent end faces of the hub member and the reaction member.  A fluid actuated piston is provided for moving the reaction member between a disengaged position, wherein the teeth are not engaged and the countershaft is free to rotate in either direction, to an engaged position, wherein the teeth are engaged and the countershaft is free to rotate in only one direction.

Title: File compression processor
Inventor: ISHII MASANORI
IPC: G06F3/06
Filed: 1993-10-20
Abstract: ABSTRACT OF THE DISCLOSURE          A file compression processor of the present invention comprises a file status monitor which compares the current available capacity on the file unit to record files and the threshold value predetermined as the upper limit of the available capacity and a file compression portion which compresses a file on said file unit when the file status monitor judges that the current available capacity is smaller than the threshold.  It further comprises a file attribute controller which stores the control information for the files recorded on the file unit including the last access date, the number of accesses, whether the file is already compressed or not and a search portion which searches for files not yet compressed with low access frequency based on the control information so as to select files to be compressed for compression by said compression portion and a compression method selector which determines the data type and the access frequency of the file for compression by said compression portion based on the control information, selects the file compression method suitable for said data type and the access frequency and instructs said compression portion to execute processing by the selected compression method.

Abstract: A portable bathing unit for use with bedridden patients is disclosed.  The bathing unit includes a bath tub supported by a carriage which is movably positionable  in the proximity of a patient.  Casters depend from the bottom of the carriage housing to permit the portable bathing unit to be rolled along in an upright posture.  Additional casters are also attached to the rear of the housing which permit the portable bathing unit to be turned up on its rear and transported through narrow doorways.  Water delivery and retrieval is accomplished through the use of a submersible pump and a segment of conduit.  A whirlpool bath tub may be employed if desirable.  When the bath tub is not in use, the portable bathing unit is convertible into an article of furniture.  The housing of the carriage forms armrests and a backrest, and a cover conceals the bathing chamber and forms a seat.  A valance drapes around the bottom of the carriage to conceal the casters thereunder.   Is should be noted that the casters elevate the housing so as to permit the legs of a hoist to pass thereunder and permit the boom of the hoist to extend over the bath chamber.

IPC: G01N33/49
Filed: 1993-10-28
Abstract: ABSTRACT OF THE DISCLOSURE   A patient's health is diagnosed by centrifuging blood samples in a transparent tube, which tube contains one or more groups of particles such as lyposomes or plasticbeads of different densities for each group. Each group of density-defined particles carries antigens or antibodies which are specific to a complement antigen or antibody which may be in the blood sample being tested, and which are indicative of the patient's health. A label-tagged antibody which is specific to all bound antibody/antigen couples is added to the blood sample so as to form labeled antibody+antigen-antibody complexes (AAAC) in the blood sample. Upon centrifugation, the complexed particles will settle out in different areas in the tube according to the respective density of the particles, and the degree of label emission of the particle layers can enable qualitative or quantitative analyses of the blood sample to be made. Unbound labeled antibodies will be washed away from the complexed layers by the washing action of the descending blood cells during the centrifugation step. Unbound labeled antibodies will thus not interfere with the analysis.

Title: Method of transmitting a data stream, transmitter and receiver
Inventor: KOPPELAAR ARIE G C
IPC: H04B1/04
Filed: 1994-02-07
Abstract: ABSTRACT: Method of transmitting a data stream, transmitter and receiver.   The invention relates to a method of transmitting data by modulating a frequency multiplex of carriers at a relatively low symbol rate, such as in OFDM. According to the inventive method, intersymbol interference is deliberately introduced at the transmitter side to reduce cross-talk between data of different carriers at the receiver side, such as to simplify an equalizing device in a receiver. The intersymbol interfer-ence at the transmitter side is introduced after the frequency multiplex modulation has taken place, by repeating groups of output symbols produced by an IFFT transformer and subsequently shaping these repeated groups by means of symbol-by-symbol scaling with coefficients constituting a window function. Subsequent shaped and repeatedgroups of these output symbols mutually overlap.

Title: Process of degumming vegetable oil by means of enzymes
Inventor: BUCHOLD HENNING
IPC: C11B3/00
Filed: 1994-11-17
Abstract: ABSTRACT               The vegetable oil to be degummed is adjusted to a pH from 3 to 6 and is mixed with an aqueous enzyme solution, which contains one of the enzymes phospholipase A1, A2 or B. In a degumming reactor the enzymes are permitted to act in the oil at temperatures from 20 to 90°C with stirring.

A substantially sludgefree solution, which contains used enzymes, is thus recovered and is recycled at least in part to a location preceding the degumming reactor. The content of re-cycled used enzymes in the total amount of the enzymes dis-persed in  the oil is at least 10%.

Title: Inertial filter
Inventor: DE WITT JAMES J
IPC: B01D45/04
Filed: 1995-01-24
Abstract: This invention relates to an inertial filter which utilises  differential  fluid  velocity  of  a  fluid flowing   through   fluid   passageways   to   remove particulate matter entrained in said fluid.   The filter has  a plurality of  baffle  plates  located within a housing.   Each baffle plate has a medial deflector  plate  from  which  extends  a  pair  of lateral deflector plates.   The plates have flanges and adjacent plates are cooperable in use to form a fluid   passageway   through   the   filter.      The orientation and configuration of  the  flanges  and plates form at least two areas where fluid flowing between the plates is alternately speeded up and slowed down.   As the fluid flows centrifugal force flings particulate matter entrained in this fluid outwardly where it collects on the plates,  flows operatively   downwardly   along  the   plates,   is collected in a channel towards the operative bottom of the filter and is removed.
