Title: Tablier escamotable pour couvrir de facon continuelle le puits d'un verin a empattement variable
Inventor: PROULX ROLAND
IPC: E04H5/06
Filed: 1991-05-24
Abstract: Un  tablier  escamotable  pour  couvrir  de façon continuelle le puits d'un vérin à empattement variable servant à élever en concert avec un vérin fixe des véhicules de différentes longueurs comprend deux  séries  de  panneaux  articulés positionnées  de part et d'autre du vérin au niveau du plancher afin de recouvrir en totalité l'ouverture du puits.   Les panneaux  articulés sont  guidés  horizontalement  au niveau  de  l'ouverture  par  des  guides  horizontaux montés  sur  les murs  longitudinaux du puits  et,  à chacune des extrémités de ce dernier,  par des guides arqués  et  ensuite  projetés  vers  le  bas  servant également  à   accommoder  l'excédent  de  panneaux articulés selon la position relative du vérin le long de la chambre.   Ainsi,  lorsque le vérin est déplacé horizontalement dans la chambre, il entraîne les deux séries  de  panneaux  articulées,   certains  panneaux émergeant de la chambre à l'une de ses extrémités alors  que   d'autres  panneaux  s'escamotent   dans celle-ci à son autre extrémité.   Par conséquent,  le tablier  recouvre  de  façon  continuelle l'ouverture pratiquée par le puits pour toutes les positions du vérin  dans  la  chambre.     Les  panneaux  articulés s'engagent  dans  les  guides  au  moyen  d'essieux porteurs qui servent également d'articulation entre chaque paire de panneaux successifs.

Title: Improved slotted suture anchor and method of anchoring a suture
Inventor: HAYHURST JOHN O
IPC: A61B17/86
Filed: 1991-06-28
Abstract: A suture anchor (10) for securing a suture (20) to body tissue (38) in an arthroscopic surgical procedure. The suture anchor is an elongated tubular member (12) having first and second ends (14,16). The distal or terminal end (24) of the suture is secured to the first or leading end (14) of the suture anchor (10) with the suture (20) extending through the suture anchor (10). A slot (18) is formed on the suture anchor (10) which extends from the second or trailing end (16) of the suture anchor (10) toward the leading end (14) of the suture anchor (10). The suture anchor (10) is inserted in a first position with the suture (20) extending through the suture anchor (10) from the leading end (14) of the suture anchor (10) to the trailing end (16). The suture (20) shifts from the first position approximately 90 degrees to a second position wherein the suture (20) extends from the leading end (14) of the anchor to the base (26) of the slot (18) with the length of the suture anchor (10) extending transverse to the free end (25) of the suture (20) located outside of the suture anchor (10). The method disclosed includes the steps of inserting the suture anchor (10) with the suture (20) extending longitudinally through the anchor (10) and shifting the orientation of the anchor (10) until the suture (20) extends through a slot (18) in the anchor (10) with the anchor (10) disposed in the body tissue (38) generally transverse to the free end (25) of the suture. A series of stop members, such as spheres, ribs or ridges (50, 72, 92), can be molded or placed on the suture (20) for mating with a locking member (52, 74, 90) in order to hold torn or fractured pieces of body tissue together until they are reattached or healed.

Patent CA-2053412-A1 (CA)
Inventor: MOROHASHI MASAYUKI
IPC: C13B20/14
Filed: 1991-10-11
Abstract: ABSTRACT       Ion-exchange resins and a process employing the resins are provided for separating low molecular weight weak organic acids from liquid mixtures.  Exemplary of such acids are those having eight carbon atoms or less such as formic acid, lactic acid, acetic acid, maleic acid, fumaric acid, citric acid and the like.  The resins are gel-type, weak-base, anion-exchange resins which are characterized by their being prepared from lightly cross-linked copolymer beads which are subsequently post-polymerization cross-linked in the presence of a Friedel-Crafts catalyst.  When functionalized with weak-base exchange groups, the resins exhibit high operating capacity with respect to retention of the weak organic acids.  The process may be used to purify, for example, sugar solutions used in preparing foodstuffs like high fructose corn syrups and fruit juices.  In another embodiment, the process recovers the weak organic acids from liquid mixtures.   38,562-F

Title: Method and apparatus for producing helical slices
Inventor: CIMPERMAN FREDERICK J
IPC: B26D7/06
Filed: 1992-02-05
Abstract: Abstract of the Disclosure A method and apparatus for producing helical slices (4) of an object, such as a potato.  The apparatus includes a rotatably mounted knife assembly (21, 29, 31) having one or more sets of knife blades (23, 24) arranged in a spiral pattern. Each set of knife blades produces a set of helically shaped potato slices.  The spiral arrangement of each blade set reduces the torque needed to slice an object using the knife assembly.  The knife assembly includes a knife bearing (31) rotatably mounted within a housing (33).  To rotate the knife assembly, a gear (35) engages and drives an outer annular surface of the knife bearing.  A liquid is injected through a channel (12) within the knife bearing housing, and preferably also through a channel (12a) within the gear mounting member, to align and lubricate the rotating knife assembly and flush fragments of the objects being sliced from the knife assembly and gear.     In a preferred embodiment, the inventive apparatus includes two sets of slicing blades (82, 83, 84, 85), for producing two sets of intertwined helical product slices. A curved separator tube (100), which extends downward from the slicing blade area, disentangles the pair of intertwined slices having the smallest radius, as the blade assembly and the separator tube rotates as a unit.

Title: Transmissive active fiber-optic star coupler for a network system
Inventor: LIAW JY-WANG
IPC: H04B10/272
Filed: 1992-07-14
Abstract: ABSTRACT OF THE INVENTION     Transmissive Active Fiber-Optic Star Coupler for  a Network system A   fiber-optic   star  coupler  is   configured   by associating fiber amplifiers and passive fiber-optic  star couplers  to  form a transmissive N*N  active  fiber-optic star coupler.  The star coupler mainly contains 4*4 active fiber-optic  star    couplers and 2*2 3dB  passive  fiber-optic  couplers acting as basic optical elements,  wherein each  of  the  4*4  active  fiber-optic  star  coupler  is composed  of  six  units of 2*2 3dB(or two  units  of  4*1 optical coupler), a dichroic coupler, an optical amplified fiber, and an optical isolator. By   using a plurality  of 4*4  active fiber-optic star couplers and 2*2 3dB  passive fiber-optic  coupler,  it is possible  to  configure  any desired  configuration of transmissive N*N  active  fiber-optic star coupler. The number N may be any integral power of  2.  The coupler in such a  configuration    uses  less pumping  sources and associated optical elements, and  has the  advantages  of compensating the  splitting  loss  and excess  loss  of  the coupler,  and  therefore  making  it possible to expand the amount of connected terminals. As a result,  the cost of the coupler may be   reduced  by  60% comparing  to  that  of the prior art.  In  addition,  the coupler   can  adapt  to  various  pumping  sources   with different   wavelength  to  meet  the  real  demands   and conditions of the network system (FIG.1B)
