Patent EP-0192443-A2 (EP)
Inventor: MINTZ MICHAEL D
IPC: A61B17/32
Filed: 1986-02-17
Abstract: An apparatus is provided for implementing a standardized skin incision which apparatus includes a housing (14) having a base containing an elongated slot (21). The base is adapted to be held flush against a patient's skin prior to making an incision. The housing (14) has an internal hollow (30) which contains a pivot arm (60) having a first pivotal end and a second end having a cam follower (61). Located within the housing is a cam surface (50) upon which the cam follower (61) of the pivot arm (60) rides. The pivot end of the arm (60) contains a cutting edge (71) and is coupled to the housing such that it is enabled to move transversely while pivoting. The cam surface (50) which is a convoluted surface controls the path of the pivot arm (60) and therefore controls the path of the cutting edge (71) as it enters the slot (21) when triggered. The device produces a standard incision of a given length and a given depth as controlled by the reciprocating pivot point and the cam surface. The device is completely disposable and further possesses the advantage that the cutting edge (71) is always located within the housing (14) except when the unit is triggered where the edge (71) traverses and projects through the slot (21) in the housing (14) for an extremely short period of time. The unit can be fabricated from plastic and sterilized prior to use and hence it is completely disposable.

Abstract: It was found that polyfeniren oxadiazole is heat treated at a high temperature above 2800°C under normal pressure thereby to be easily formed into a crystalline graphite. A graphite film obtained by graphitizing a film-like polyfeniren oxadiazole has a sufficient flexibility while being monocrystalline. The thus obtained graphite film is able to have a sufficient area, which is plastered on a base plate thereby to be used as a reflecting mirror and a lens for radiation such as X-ray, neutron ray, etc.

Abstract: A sod harvester (10) in which sod is cut, conveyed upwardly, and then travels downwardly over a floppy conveyor (78) and falls into a roll forming enclosure (76) formed with a bottom conveyor (86) and a vertical conveyor (92). The floppy conveyor (78) swings downwardly at the start of roll forming, to reduce the free fall of the sod, and swings upwardly as the roll (162) grows. When the roll (162) is formed, the bottom conveyor (86) is unlatched and tilts downwardly to discharge the roll (162), at the same time putting into cocked position a core tube injector arm (202, 206). When the roll (162) discharges, the bottom conveyor (86) snaps upwardly, releasing the core tube injector arm (202,206) which injects a fresh core tube (164) into the roll forming enclosure (76). The sod is rolled with its grass side outwardly to facilitate laying and to protect the grass roots. A tray (266) on a cart (222) at the end of the harvester receives the discharged roll (162) and can convey it to either side of the cart. When the tray (266) reaches either side of the cart, a cam (270, 272) tilts the tray (266) to discharge the roll (162) onto the ground clear of the next pass of the harvester.

Abstract: This invention relates to apparatus for the cryo­preparation of biological tissue samples for ultrastruc­tural analysis. The use of the apparatus comprises vitrifying a biological tissue sample under cryogenic temperature conditions and ultra low vacuum conditions. The depressurized, vitrified tissue sample is brought to equilibrium in a thermally conductive sample holder at a temperature of less then -140°C. The tissue sample is then dehydrated while maintained in a state of thermal equilibrium. After reaching equilibrium the tissue sample is optionally infiltrated with a degassed resin followed by a polymerization of the resin to form an embedded tissue sample.

Abstract: A polyurethane polymer is prepared by reacting such as by spraying onto a substrate or an open mold, a caprolactone polyol with a methylene dipara phenylene isocyanate (MDI) in the presence of a catalyst to provide the polyurethane polymer. The reaction of difunctional caprolactone polyols with low functionality MDI or MDI prepolymer in the presence of a metal, e.g. tin, catalyst and an amine, e.g. triethanol amine, provides for flexible and rigid polymer films of substantially no porosity. The reaction of a caprolactone polyol with an MDI prepolymer having a functionality of 2.4 or less with an ethylene oxide capped polypropylene oxide polyol in the presence of a trimerization catalyst provides for a high heat distortion temperature polymer. A two part kit for use in preparing the urethane polymer comprises an A-side composition including the MDI moiety and a B-side composition including the polyol, catalyst and the amine.

Abstract: A layer (2) of a material of substantially the same chemical composition as a known high Tc ceramic superconductor is formed on a substrate (1) by sputtering and is selectively irradiated with a laser beam (3) so as to define irradiated (4) and non-irradiated (5) regions. The sputtered layer (2) is disordered and has many lattice defects and imperfections and thus is basically non-­superconducting, but by irradiation with a laser beam (3) the sputtered layer (2) is melted and then recrystallizes into an ordered and superconducting material. In another embodiment, the sputtered layer is already superconducting and is changed into a non-superconducting material by irradiation with a laser beam, said irradiation being carried out at a relatively low temperature in order to rapidly cool the irradiated portion and convert it into a disordered, non-superconducting state. 
     A puferred substrate is chosen from the group containing YSZ, yttria and zirconia, which have thermal expansion coefficients substantially matching that of superconducting oxide materials.
