Abstract: A magneto-optical recording medium is consisted of a recording layer, a readout layer and a writing layer.  The readout  layer  is  made  of  rare  earth-transition metal alloys wherein an easy magnetization axis is parallel to the recording layer at room temperature,  and the  easy magnetization axis is perpendicular to the recording layer as the temperature of the readout layer is raised above a predetermined temperature by irradiating thereon with a light  beam.   The  writing   layer  is   made  of   rare earth-transition metal alloys having such coercive force that a magnetization direction thereof is switched by an external magnetic  field at  room temperature  and  Curie temperature  that  is  above  Curie  temperature  of  the recording   layer.    With  the  above  arrangement,   an overwriting function can be achieved by adjusting a light intensity of the light beam so that the temperature falls within the range between the Curie temperature of  the writing layer and the Curie temperature of the recording layer,  or  above  the  Curie  temperature  of  the writing layer.

Abstract: A surgical stapling instrument for performing a circular anastomosis stapling operation is provided. The surgical instrument includes a stapling head assembly mounted by a curved shaft to an actuator handle assembly and incorporates an improved actuator mechanism for transmitting the required operating forces and movements from the actuator handle assembly through the curved shaft to an anvil and staple driver of the stapling head assembly. The stapling head assembly includes a longitudinally movable trocar detachably secured by one or more retainer clips on a hollow shaft of the anvil. When the trocar is retracted, the anvil shaft slides into a central support tube which aligns the anvil axially and circumferentially with a staple holder on the stapling head assembly. The retainer clips are locked against the trocar by the support tube and transmit tension from the trocar to the anvil with no tension load on the anvil shaft. The actuator mechanism permits adjustment of the anvil gap to produce a desired staple height and precludes actuation of the staple head assembly if the anvil gap is set outside of a predetermined range. Also, the actuator mechanism is adapted to both advance and retract the staple driver relative to the staple holder in the stapling head assembly.      Further, an improved arrangement for attaching the support shaft to the stapling head assembly and to the actuator handle assembly is provided.

Abstract: PARTIAL OXIDATION OF SEWAGE SLUDGE             (D#79,359 -F) ABSTRACT           An improved process for the low-cost disposal of noxious sewage sludge in a safe way without polluting the environment.   In the process, sewage sludge having a solids content of about 0.5 to 20 wt.% is concentrated by pressing in a belt filter press, optionally followed by pressing in a high intensity press.  It was unexpectedly found that the morphology of the resulting dewatered sewage sludge is changed by such mechanical   treatment   so   that   slurries   with   higher concentrations of solids are achieved.  The dewatered sewage sludge is heated,  flash evaporated and/or centrifuged,  and mixed with a supplemental fuel e.g., liquid hydrocarbonaceous and/or solid carbonaceous fuel to produce a pumpable fuel slurry having a total solids content in the range of about 50 to 70 wt.% and comprising about 10 to 40 wt.% dewatered sewage sludge and having a higher heating value in the range of about 5,000 to 14,000 BTU/Lb.   The fuel slurry may be reacted by partial  oxidation  in  a  conventional  gasifier  to  produce synthesis gas and/or fuel gas.  The thermal energy in hot by-product steam and flue gas streams are used to heat the dewatered sewage sludge.   In one embodiment,  the pumpable slurry of dewatered sewage sludge and supplemental fuel is burned by complete combustion in a furnace or incinerator for the production of steam.

Abstract: A multi-purpose baby wrap which converts to a blanket, a bunting, a pad or a carrier sling.  The wrap comprises two major parts:  a full sized baby blanket and a large, detachable, bifurcated pocket.  The pocket covers the lower half of the blanket and is sized to fit children from birth to about two years, with the pocket covering the child's legs and torso up to the waist.  A baby's diaper may be changed without removing the baby from the wrap by simply unfastening the bottom and sides of the pocket and lifting it to expose the lower half of the baby.          For use of the wrap as a bunting, the baby is placed feet first in the pocket; the blanket is then rolled around the baby and secured snugly about his or her midriff with one or two short straps.  With the blanket so secured, the apparatus in plan view presents the appearance of a rectangle.  At each corner of this rectangle, a fastener is provided for attaching a pair of elongated straps to the wrap.   Crossed in the center, there elongated straps, with the wrap, form a sling for carrying the baby.  Alternately, for transport of an infant in a car seat or stroller, the wrap is equipped with overlapping openings formed in the blanket and in the pocket, respectively.  These openings allow a safety belt for the car seat or stroller to be inserted between the baby's legs.

IPC: H04M7/00
Filed: 1993-04-16
Abstract: MULTI-SYSTEM NETWORK ADDRESSING                  ABSTRACT OF THE DISCLOSURE      Storage locations, such as voice mailboxes are addressed on a plurality of widely distributed host systems, connect via a network, by defining logical domains each of which may include storage locations on more than one host system.  The domains are defined by address tables which indicate which host systems provide ranges of address locations.  Transfer of data between domains is simplified by the use of translation tables.  One type of translation table is an alias table which has entries containing a range in the originating domain, a new domain and a starting point for a range in the new domain, thus defining a one-to-one correspondence between the ranges in the two domains.          Another translation table is a gateway table which defines a gateway to a new domain when an input address has characteristics matching a prefix, number of digits, or both, of an entry in the gateway table.  Upon finding the closest possible match in the gateway table, the portion of the input address after the prefix, if any, is used as the address in the new domain.

Title: Turtle filtration system
Inventor: SAUMURE RAYMOND A M J JR
IPC: A01K63/04
Filed: 1993-04-20
Abstract: RECOMMENDED FORMS                        Form 24 (ss. 21, 31, 34, and 142) ABSTRACT           In  order to filter aquarium  water, it is  known that external and internal filters may be used.  In this invention, an external biological  filter and  an  under-gravel filter  are modified  by integrating them into  a single filtration  system.  This  system can then  remove  large  amounts  of organic  waste  produced  by aquatic turtles more effectively.  An external filter is attached to  a  tubing system,  which  lies concealed  beneath  a modified under-gravel filter mat.   The  tubes are divided  into long  and short  sections  to  increase  the surface  area  covered  in the filtration  process.   Consequently,  waste which would normally have  accumulated in  the gravel,  is sucked  through it  and the filter mat pores.  The dirt is then siphoned from the aquarium to an  external filter, where it is filtered by a semi-porous sponge and  returned to  the  aquarium.   The  TURTLE FILTRATION  SYSTEM incorporates  a bracketed basking platform as part of its design. The  platform  maintains optimal  filtration  levels, and  usable space.   A light  fixture was  designed to  fit over  the basking platform.  The  external filter  is modified to  include a  water guide and turtle guard.  The result of this system is an aquarium that need only be  cleaned on an annual basis,  with a bi-monthly cleaning of the  filter material.   The system  is therefore  low maintenance, hygienic,  and cost  efficient.  Added  benefits are that  the  system  is  virtually  noiseless,  escape  proof,  and aesthetically pleasing.
