Abstract: HYDRO-PLANETARY POWER DIVISION SYSTEM          Abstract of the Invention A system for dividing rotary power to two or more output shafts includes planetary cluster cages that are associated with the output shafts and which are interconnected by a hydraulic circuit.  In instances where the output shafts rotate at speeds different from one another, a portion of the power from the source is directed through the hydraulic circuit to cause rotation of spiders carrying plane-tary gears within the cluster cages coupling the output shafts to a primary driveshaft.   The power division system is modular in nature in that the hydro-planetary cluster cages and associated drive axles can be easily added or deleted as desired.

Granted: 1999-04-06
Abstract: A motor assembly includes a stationary assembly having a plurality of winding stages adapted to be electrically energized to generate an electromagnetic field and a rotatable assembly including a plurality of permanent magnet elements in magnetic coupling relation with the stationary assembly.  The motor assembly also includes first and second substantially flat end members parallel to each other and having inner facing sides between which the stationary  assembly  and  the  rotatable  assembly  are located.

Control circuitry is connected to the winding stages and positioned adjacent the outer side of the first member, for applying a voltage to one or more of the winding stages at a time and for commutating the winding stages in a preselected sequence to rotate the rotatable assembly about an axis of rotation.  A cap on the outer side of the first member forms a closure with the first  member within which  the  control  circuitry  is located.  A connecting element engages the second end member and the cap and is adapted to urge the second end member and the cap toward each other thereby supporting the first end member, the stationary assembly and the rotatable assembly therebetween.  Alternatively,  an adapter having first and second opposite sides may be positioned between the first end member and the cap.

Title: Use of solutions of atelocollagen and polyholosides, for example glycosaminoglycans, for the manufacture of microcapsules, microcapsules produced in this way, processes for the manufacture of such microcapsules and cosmetic, pharmaceutical or food compositions in which they are present
Inventor: HUC ALAIN
IPC: A61K8/73
Filed: 1990-01-31
Granted: 1999-08-24
Abstract: The invention relates to microcapsules with a mixed wall of crosslinked atelocollagen and polyholosides, for example glycosaminoglycans, and to processes for the manufacture of the said microcapsules.      According to the invention, the microcapsules comprise a mixed wall of crosslinked atelocollagen and polyholosides, for example glycosaminoglycans, the proportion of polyholosides, for example glycosaminoglycans, relative to the atelocollagen preferably being between 18 and 50% by weight. These microcapsules can be manufactured either by a process involving interfacial cross-linking or by the extrusion of a laminar flow which is broken up by vibrations into individual droplets, which fall into a crosslinking bath.      These microcapsules are biocompatible by virtue of the presence of atelocollagen, which has most of the advantageous properties of collagen, namely a very low antigenicity and a perfect biodegradability. They are therefore particularly suitable for the manufacture of cosmetic, pharmaceutical or food compositions.

Title: Multiprocessing system having a single translation lookaside buffer with reduced processor overhead
Inventor: KADAIRA GIZO
IPC: G06F12/10
Filed: 1990-02-09
Granted: 1994-05-10
Abstract: ABSTRACT OF THE DISCLOSURE     A multiprocessing system comprises a single translation lookaside buffer partitioned into a plurality of buffer areas, and a plurality of directory registers respectively corresponding to the buffer areas. Each register is partitioned into a first field and a second field having bit positions respectively assigned to processors. A directory controller selects one of the registers and writes a segmented virtual space identifier of a requesting processor into the first field of the selected register and a bit "1" into its second field in a position assigned to the requesting processor. If, during a nonshared-access mode, the directory controller accesses a buffer area corresponding to the selected register to load a copy of the translation tables from a main memory into the buffer area.          During a shared-access mode, the directory controller searches all registers to detect a first one whose first field contains the segmented virtual space identifier of the requesting processor and whose second field contains a bit "1" in a position assigned to that processor and a second register whose first field contains the same identifier as the first and whose second field contains a bit "1" in a position assigned to a master processor to indicate the denial of access right. The bit "1" of the first register is reset to zero and a bit "1" is set in the second field of the second register in a position assigned to the requesting processor to indicate the grant of access right. In a subsequent, nonshared-access mode, one of the bits "1" in the second register is reset in a position assigned to the requesting processor and a copy of the translation tables is loaded into the buffer area corresponding to the register containing instructions issued from the requesting processor.

Title: Method and device for driving multiple latching relays
Inventor: BOURGOUIN JACQUES
IPC: H01H47/00
Filed: 1990-09-12
Granted: 1996-10-15
Abstract: Multiple  latching relays are driven on their first side by all but one of the parallel outputs of a  shift register.  Each relay on the same shift register is driven on its second side by the remaining parallel output of the shift register.   A clock signal is fed to all shift registers and causes each shift register  to shift all of its information one cell on the selected edge of the clock  signal.  A latch signal  or blanking  signal is used to prevent the  shift registers from outputting their  information  to the relays during shifting.  A serial  data  message is inputted to the first shift register and then from the first shift register sequentially to all of the other shift  registers.   The information in the serial data message is  such that after shifting of all shift registers is complete the appropriate signal will be on each side of each latching relay to cause it to either change or remain unchanged.  The result is that one serial data line, one clock line and one latching or blanking line controls all of the relays and that additional relays can be controlled simply by  adding more  shift registers and sending more data down the serial data line.

Title: Method of and apparatus for removing non-metallic inclusions from molten metal
Inventor: MIKI YUJI
IPC: B22D41/01
Filed: 1990-09-19
Granted: 1996-12-03
Abstract: A method of removing non-metallic inclusions from a molten metal comprises the step of simultaneously applying both a horizontal rotation of the molten metal and heating of the molten metal by induction heating.  After the simultaneous application of rotational force and heat, the induction heating may be stopped while the horizontal flow of the molten metal is maintained, so as to promote the separation of the particles of the inclusions.  The method is carried out by using an apparatus which has a vessel which contains the molten metal, a rotary magnetic field generating device surrounding the vessel, and an induction heating device also surrounding the vessel.  Each of the rotary magnetic field generating device and the induction heating device may be divided into a plurality of circumferential segments and arranged such that the segments of both devices are alternately disposed around the vessel.
