Abstract: This invention concerns an animal-human chimera monoclonal antibody whose side-effects such as anaphylaxis and serum sickness are thought to be greatly reduced when it is administered to human.  The chimera monoclonal antibody is produced by a recombinant host animal cell and consists of a variable region which recognizes a melanoma cell and is homologous to the corresponding variable region in an antibody derived from an animal hybridoma (such as mouse hybridoma D10) and a constant region homologous to the corresponding region of human antibody (such as one encoded by human Cx gene or Cy1 gene).  The production process of the chimera monoclonal antibody comprises inserting active chimeric Ig heavy and light chain genes into an expression vector and then introducing the vector into animal culture cells.

Title: Substituted aliphatic polyamide porous membranes
Inventor: FORD DOUGLAS L
IPC: B01D71/56

Granted: 1991-09-10
Abstract: ABSTRACT             Polymeric porous membranes comprising aliphatic polyamide membrane matrices having both relatively non-crystalline and relatively crystalline portions are described.           The method of preparing the porous membranes includes dissolution of an aliphatic thermoplastic polyamide (having crystalline and non-crystalline portions) into an acidic hydrolytic solvent such that the crystalline portions form a colloidal dispersion which is further formed into a film. The non-crystalline portions are precipitated in the film to form a porous membrane matrix which is reacted with an acid halide of basicity above one to provide acid radicals within the membrane. The acid halide may be derived from an aromatic carboxylic acid or an aromatic derivative of a chlorosilane. The substituted aliphatic polyamide porous membranes lend themselves to the preparation of chemical derivatives of the membrane which are not readily available by aqueous synthesis and to increased density of derivatives which otherwise may be prepared in water.

Granted: 1991-09-10
Abstract: ABSTRACT OF THE DISCLOSURE          A degaussing circuit for a video display apparatus eliminates residual degaussing current flow during operation of the video display apparatus.  A capacitor is connected between the energizing coil of the degaussing relay and the source of energizing voltage.  Application of the energizing voltage to the relay energizing coil energizes the relay and initiates degaussing of the cathode ray tube of the video display apparatus, and also causes the capacitor to begin charging.  As the capacitor becomes charged, the degaussing relay becomes deenergized, thereby terminating degaussing current flow.  The capacitor charging time constant is selected to allow sufficient time for degaussing to occur before deenergization of the degaussing relay.

Abstract: : Dispositif pour engendrer des ondes acoustiques par percussion d'une masse chutant sur un élément-cible solidaire de moyens d'ancrage escamotables. La masse se déplace dans un corps allongé sous l'action combinée de la gravité et de moyens élastiques depuis une position de relevage jusqu'à une position d'impact. Le réarmement après la chute est effectué en soulevant la masse par un écrou immobilisé en rotation, au moyen d'une tige filetée reliée à des moyens moteurs réversibles et en la bloquant en position haute soit par une barre escamotable déclenchée par le retour de l'écrou en position basse soit encore par des moyens magnétiques télécommandés. Les moyens d'ancrage comportent par exemple un "packer" et un moyen de couplage élastique. Application à la production d'impulsions sismiques par exemple.

Title: An antimicrobial composition containing silver compound
Inventor: PRATT ALLIN SIDNEY
IPC: A61L2/16
Filed: 1987-07-02
Granted: 1992-07-28
Abstract: ABSTRACT          An antimicrobial composition for topical use or for incorporation into a coating or structural composition comprises an antimicrobial silver compound, preferably silver chloride, deposited on a physiologically inert oxidic  synthetic  particulate  support  material  in particulate  form.   A  preferred  support  material  is titania containing one or more of the crystalline forms anatase, rutile, and brookite.

Title: Electromagnetic shear lock
Inventor: SOWERSBY ALAN C
IPC: E05C19/16
Filed: 1987-07-27
Granted: 1992-02-25
Abstract: ABSTRACT      An electromagnetic shear lock comprising an electromagnet having an E-shaped cross section with a coil positioned about the middle leg of the E is mounted in a doorway and an armature having a centrol projection is mounted to the door, where the middle leg of the E is shortened to define a recess to receive the armature projection and provide mechanical reinforcement against shearing when the electromagnet is energized.  The inner edges of the outer legs of the E and the edges of the armature projection are matingly beveled to prevent binding when the electromagnet is de-energized and an airgap is defined between the middle leg of the E and the armature projection to overcome any effects of residual magnetism.

Abstract: ABSTRACT OF THE DISCLOSURE    A digital speech signal sampled at a predetermined interval is stored in a memory.  An LPC coefficient is developed from the speech signal and thus developed LPC coefficient specifies coefficient of a recursive filter.          The speech signal read out from the memory is backwardly supplied to the recursive filter in the reverse order to the sampling order of the speech signal.  A plurality of multi-pulses are determined on the basis of the crosscorrelation coefficients between the speech and an impulse response of the recursive filter obtained by the recursive filter.

Title: Apparatus for reproducing selectively loaded discs of different diameters
Inventor: OTSUKA MINORU
IPC: G11B33/02
Filed: 1987-08-20
Granted: 1992-03-10
Abstract: PATENT     APPARATUS FOR REPRODUCING SELECTIVELY LOADED             DISCS OF DIFFERENT DIAMETERS              ABSTRACT OF THE DISCLOSURE         An apparatus for reproducing signals recorded on a selected one of first and second discs of different diameters, such as, a relatively large diameter video disc and a relatively small diameter compact disc, has a disc-transporting tray mounted for substantially horizontal movement between a first or operative position within a housing and a second or disc-inserting and withdrawing position in which the tray projects substantially forwardly from the housing through an opening at the front of the latter, the tray having first and second disc mounting portions dimensioned for receiving and holding the relatively large and small diameter discs, respectively, and the second or relatively small-diameter disc mounting portion being disposed at a front part of the tray and substantially contained within the confines of the first or large-diameter disc mounting portion for minimizing the required size of the tray, and hence the overall size of the apparatus.  Further, access to the second or relatively small-diameter disc mounting portion of the tray for inserting or withdrawing a compact disc may be had when the tray is only partly projected from the housing, thereby to reduce the time required for loading and unloading or exchanging a compact disc.
