Abstract: ABSTRACT : Ultrasound transducer.     An ultrasound transducer, comprising a substrate (10) which forms a backing medium, a layer of piezoelectric material (20), and one or more matching layers (30,40) whose acoustic impedance has a value between that of the piezoelectric material and that of a foremost, propagation medium (50). The matching layer (layers) is (are) provided exclusively between the piezoelectric material (20) and the foremost, propagation medium (50). The acoustic impedance of the backing medium (10) is sufficiently high with respect to the acoustic impedance of the piezoelectric material for the backing medium to be considered to be rigid, the thickness of the layer of piezoelectric material (20) being equal to one quarter of the wavelength associated with the resonant frequency of the transducer.

Abstract: FEMORAL RASP                         Abstract A femoral rasp for preparing an intramedullary canal for receiving the stem of a femoral hip pros-thesis comprises a body section generally divided into a wide proximal portion and a substantially longer narrow distal portion.  The body section has a shape that generally corresponds to the stem of a femoral hip prosthesis to be inserted into the prepared cavity. A plurality of spaced apart cutting teeth are located on selected portions of the outside surface of the body section for removing cancellous tissue and bone. A smooth surface on the lateral face of the body section at the free end of the distal portion presents violation of the lateral cortex upon insertion of the body section into the intramedullary canal.  Removal of the body section and insertion of the hip prosthesis results in a glove fit between the stem of the prosthesis and the cavity formed by the femoral rasp.

Abstract: HYDRAULIC CONCENTRATOR     ABSTRACT OF THE DISCLOSURE     The invention includes a concentrator that pressurizes and provides an enriched liquid suspension to a separator.  In the concentrator, the incoming liquid suspension is driven by a  diaphragm pump into a funnel-shaped accumulator that is closed at its top.          Some of the heavier particles go directly to the bottom of the accumulator, but the lighter particles and the remainder of the suspension are forced to flow through tubes that extend from the top of the accumulator up-ward on a helical path.  Further particulate matter settles out in the helical passages and migrates to the bottom of the accumulator. From the accumulator, the concentrated suspension is fed under pressure to a separator that includes an inclined chamber that is completely filled with liquid.  A stream of wash water is directed from the lower rear end of the separator towards the upper front end of the separator.  An island in the separator includes a rearwardly opening passage through which the enriched suspension from the concentrator enters the separator.  The floor and ceiling of the separator chamber define between them an undulating passage from the back end to the front end of the separator.          The separated material is discharged from the separator through a unique pinch valve, while the wash water and finer particles are forced from the front end of the separator chamber through an upwardly directed helical path which provides further separation.

Abstract: DETERGENT COMPOSITION WITH SILICONATE-ZEOLITE            AND SILICATE BUILDER                      ABSTRACT           The preparation and applications of anionic siliconate-zeolite composites are disclosed.  The composites are formed by coating the surface of zeolite particles with an aqueous solution of an anionic functional organo-siliconate.  The composites are particularly useful as components of soluble silicate containing detergent compositions since they do not agglomerate with the soluble silicates to form large insoluble particulates that can deposit on fabrics during laundry. Detergent compositions containing the composites are disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE A highly reliable shadow memory system is able to survive multiple fast sequence power failures and includes a volatile main memory and a shadow memory subsystem which continually monitors write accesses to the main memory.  The shadow memory subsystem includes a disk drive or shadow memory storing a copy of the data in main memory.  As the main memory contents are altered, the shadow memory is continually updated to reflect the changes while main utility power is available. In the event of a main utility power failure, backup power is required to store main memory data in the shadow memory for only a few storage locations for which the updating of theshadow memory may lagmain memory data changes. Consequent-ly, only a small portion of available battery backup power is required to preserve all main memory data and the system can withstand multiple rapid succession power failures without loss of data.

Abstract: ABSTRACT          Tumours are sensitized to radiation by administration of 5-chlorodeoxycytidine (5-CldC) or 5-halo-2'-halo-2'-deoxycyti-dine or uridine derivatives.  Tetrahydrouridine (H4U) and/or 2'-deoxytetrahydrouridine (dH4U) is preferably coadministered with the deoxycytidine derivatives to inhibit deamination of the deoxycytidine derivatives.  Optional prior concurrent treatment with agents to reduce the amount of competing metabolites to favor CldC , such as 5-fluorodeoxyuridne, results in a procedure that significantly increases the dose effects of X-radiation. Pharmaceutical compositions suitable for the sensitization of tumors to radiation are also disclosed, as are novel compounds.

Abstract: ABSTRACT OF THE DISCLOSURE           A laser beam is widened in one dimension to cover an array of a substantial number of electro-optic gates. The beam is divided by the gates into a plurality of potential spot-forming beams.  The transmission of each such beam to a photosensitive surface is selectively inhibited in accordance with a pre-determined pattern or program, while the beams are swept relative to the photosensitive surface to form characters and other images.  Preferably, the gates are formed by a wafer of PLZT electro-optoc ceramic material, with a large number of closely-spaced electrodes on the surface, in cooperation with a crossed polarizer.          Preferably, the beams are collimated and a traveling lens and reflector combination is moved parallel to the photo-sensitive surface in the collimated beams to space the spots on the film from one another.  The collimated beams are made convergent so that a relatively small, light-weight lens can be used to compose relatively long lines of text without excessive loss of light or vignetting.  Also provided are a relatively simple but stable lens-reflector carriage and rail structure on which the carriage travels in order to sweep the beam relative to the photosensitive surface.

Abstract: A FLEXIBLE DUPLEX DUAL PORT SERIAL LINK CONTROLLER                ABSTRACT OF THE INVENTION A multiple port serial link controller printed wiring card is shown.  This printed wiring card provides at least two independent ports.  These ports may be of different types such as RS-232 interface, RS-449 interface or other serial protocols such as HDLC, SDLC or BISYNC.  These printed wiring cards may be combined in a duplex fashion to form two duplex (highly reliable) port transmission circuits.  The duplex configuration requires a minimum amount of backplane wiring.  This backplane wiring is permanent and requires no manual intervention for switching between transmission and mode types.  Switching between transmission mode type and reconfiguring for the occurrence of faults may be accomplished by an automatic processor manipulation of a number of control points.
