Abstract: A clean environment enclosure assembly (10) prevents contaminants from reaching unfinished products during the manufacturing process.   The clean environment enclosure assembly (10) includes a plurality of frames (16) which are secured to each other using various shaped brackets (60, 62, 64) to form a structural frame.  Sheets of plastic (22) extend across each of the plurality of frames (16) to complete the housing (14).  The sheets of plastic (22) are secured to side members (18) of the frames (16) by elongated caps (24) which run the length of the side members (18).  The caps (24) have  two  arms  (30,  32)  which  engage  the  two substantially parallel side walls (42) of the side members  (18) wherein detents  (38,40)  of the two arms  (30,  32)  engage  indents  (44,  46)  of  the parallel side walls (42) preventing the cap (24) from freely disengaging the side member (18).  The sheets of plastic (22) are sandwiched between the cap (24) and the side members (18).

Title: Cargo hook with weighing scale
Inventor: ENGLISH DAVID C
IPC: B64D1/22
Filed: 1993-01-21
Abstract: ABSTRACT OF THE DISCLOSURE      A cargo hook having fore and aft trunnions mounted in fore  and  aft  bearings  supported  on  frame  members  of  a helicopter or the like, is provided with strain gauges secured in a bore in the aft trunnion for measuring shear strain on the  trunnion  by  a  load  supported  by  the  cargo  hook.          Additional strain gauges are secured in the aft trunnion bore for measuring axial and Poisson forces on the trunnion as the axis  through  the  fore  and  aft  trunnions  varies  from horizontal.  The strain gauges are included in an electric circuit of a Wheatstone bridge and an indicator which converts the electric signals from the strain gauges to a readout of units of load weight. The strain gauges which measure axial and Poisson forces are connected in the electric circuit to compensate for the deviation from horizontal of the axis through the fore and aft trunnions, to provide an accurate readout of load weight applied to the cargo hook.  A low RF impedence ring is mounted in the trunnion bore to protect against electromagnetic inteference, and a passageway in the trunnion for leading electrical conductors from the strain gauges outwardly of the trunnion, is filled with a sealant for protecting the   strain   gauges   against   environmental contaminants such as dust and moisture.

Title: Femoral prosthesis component system for knee replacement surgery
Inventor: BERTIN KIM C
IPC: A61F2/00
Filed: 1993-02-23
Abstract: A femoral prosthesis component system particularly for knee revision surgery comprising a set of femoral implant components constructed around a set of geometrical constants which allows resection of the distal femur to be conducted using the intramedullary canal as a reference point and without the requirement of first measuring for a specific implant size. The construction of all the components in the set is based around a constant relationship between the intramedullary shaft and the anterior flange such that the anterior resection is the same regardless of the size of the component used and the distal and posterior resections are standard cuts made based on this relationship and the intramedullary canal reference point.      Adjustment of the distal and posterior resections to fit is made with a set of augments having dimensions also based on the standard distal and posterior resection cuts.

Title: Elimination of fish odour in cooking process (using chemicals)
Inventor: DANG MINH
IPC: A23L29/206
Filed: 1993-08-16
Abstract: ABSTRACT: Fish smell is a nuisance for home cooking, and when ventilation is not adequately it can remain in-door for hours. In this invention, gum tragacanth (tragacanth) has been found to reduce (in some cases) eliminate the smell remarkably. Salts of alginate had also been found to reduce the fish smell to some extent. Tragacanth has number of advantages over salts of alginate. Tragacanth can have a fast dispersion in cold water and shorter time of application which make it an ideal agent in many fish cooking processes. Meanwhile salts of alginate requires hot water to dissolve and the time required to reducing fish odour (smell) is three times longer than that of tragacanth.

Title: Current limiting fuse and dropout fuseholder for interchangeable cutout mounting
Inventor: HASSLER STEPHEN P
IPC: H01H9/32
Filed: 1993-09-14
Abstract: ABSTRACT    The fuseholder includes a current limiting fuse mounted within a fuse body and a lower contact and hinge assembly.  The fuse body has contact assemblies mounted on each end thereof.          The lower contact assembly on the fuse body is mounted on a hinge which  is  rotatably  supported  on  an  interchangeable  cutout mounting.   The current limiting fuse includes a fuse element spirally wound around a spider which extends the length of the fuse body.   The fuse element includes a high current fusible element and a low current fuse element.   The fusible element includes a plurality of spaced reduced areas and is supported on the spider by support surfaces which are located between adjacent reduced areas of the fusible element.  An auxiliary wire also extends the length of the fuse body about the spider.  The hinge includes a hinge member rotatably mounted on the interchangeable cutout mounting,  a connective member supporting the contact assemblies and fuse body with current limiting fuse, and a latch for latching the hinge member to the connective member in a contracted position.  The latch is connected to a trigger wire attached to the lower end of the auxiliary wire to maintain the hinge and connective members in their contracted position.  Upon the melting of the trigger wire due to a current overload, the trigger wire releases the latch thereby allowing the connective member to move to an extended position with respect to the hinge member such that the current limiting fuse drops out of the interchangeable cutout mounting.

Patent CA-2117765-A1 (CA)
Inventor: COLVARD MICHAEL
IPC: A61B18/26
Filed: 1993-04-01
Abstract: 2117765 9320895 PCTABS00027 An optical probe configured for insertion into the anterior chamber of an eye, adjacent to the cataractous lens of the eye, comprises an optical source (60) and an optical waveguide (100) connected to deliver optical radiation from the source to the probe. The optical radiation is in the form of pulses which have a repetition rate, a wavelength and an optical energy selected to cause significant ablation-induced damage to the lens within an ablation zone, and significant acoustic-induced damage to the lens within an acoustic zone, such that the acoustic zone is significantly larger in size than the ablation zone. The acoustic zone is created by generating shock waves which radiate from the ablation zone and propagate through hard nuclear material of the cataractous lens, such that the nuclear material is microfractured. The microfractured lens material is significantly more reactive to the laser pulses than prior to microfracturing, and the hard nuclear material readily disintegrates into small fragments in response to application of laser pulses.

Title: Non-spill bottle cap used with water dispensers
Inventor: ADAMS BRIAN M
IPC: B65D41/48
Filed: 1992-10-06
Abstract: A cap composed of a snap-on, tamper-evident closure is formed with a central sleeve (28). The bottom of the sleeve is closed off by a removable plug (46). The exterior of the closure is formed with a bead (58). The water dispenser is provided with an adapter consisting of an open-bottom outer sleeve (11) into which the neck (24) of the container with the closure (26) in place thereon fits. Centrally disposed in the outer sleeve is a dispenser tube (16). When the container is inverted its neck is inserted in the outer tube (11). As the neck and cap are lowered, the dispenser tube enters the cap sleeve (28) and attaches to the plug (46). Continued lowering of the container causes the plug (46) to slide out of the sleeve (28) so that liquid in the container flows out through the dispenser tube (16) into the dispenser. When the container is lifted, the plug (46)(which has been attached to the dispenser tube (16)) is pulled back into its original sealed position (fig. 1). The plug and cap are at all times discrete. The exterior skirt of the plug and the interior wall of the well sleeve (28) are seamless.
