Title: Valve assembly for venting diecasting moulds
Inventor: WYSER JOHANN
IPC: A41C3/14
Filed: 1994-01-31
Abstract: A valve assembly for venting diecasting moulds comprises a venting channel means, a venting valve communicating with the venting channel arid having an axially displaceable valve closure member, and an actuating member for operating the venting valve from an open position into a closed position. The actuating mem-ber includes a power pick up member exposed to the liquid cast-ing material escaping during the casting operation from a cast-ing chamber provided in the diecasting mould through the venting channel and being axially displaceable under the influence of the kinetic energy transmitted from the liquid casting material to the power pick up member when the liquid casting material hits the power pick up member. The power pick up member is me-chanically coupled to the axially displaceable valve closure member and includes an axially displaceable push member having an operating stroke whose length is limited to only a fraction of the length of the stroke performed by the axially displace-able valve closure member when it is driven from its open posi-tion to its closed position. The axially displaceable valve clo-sure member freely moves along a path in addition to the operat-ing stroke of the power pick up member. The actuating member further comprises a power transmission member for the transmis-sion of the impact force exerted by the liquid casting material onto the power pick up member to the axially displaceable valve closure member of the venting valve.

Title: Immortalized lymphocytes for production of viral-free proteins
Inventor: SUGDEN WILLIAM M
IPC: C12N15/11
Filed: 1995-07-27
Abstract: This invention is directed to construction of recombinant plasmids that contain the Epstein-Barr virus ("EBV") genetic information involved in the immortalization of human lymphocytes, but that lack one or more genes implicated in EBV lytic replication. The recombinant plasmids have the advantage of being able to immortalize human lymphocytes, while being incapable of generating infectious EBV particles. The invention also provides human lymphocytes that have been successfully infected and immortalized by the recombinant plasmids. These human lymphocyte clones can be used as cellular factories to produce desired proteins and as delivery vehicles for gene therapy. Additionally, the invention establishes a method by which desired proteins can be produced in immortalized cellular factories, without generating infectious EBV particles. These proteins can be the normal cellular products of immortalized human lymphocytes, or they can be proteins encoded by foreign genes, which have been cloned into the lymphocytes.

Patent CA-2158184-A1 (CA)
Title: Process for the regulation of the turning behaviour of a turntable
Inventor: JANISCH KLAUS
IPC: A61G7/10
Filed: 1995-09-13
Abstract: In a turntable (10) there is a flat, ring-shaped recess (36) on the lower side of the turning platform (12), in which recess a ring element (38) is arranged in rotatable fashion with respect thereto, which element has sliding surfaces on the top and bottom. The thickness of the ring element (38) is somewhat larger than the depth of the recess (36), so that the lower support surfaces (28, 30, 32) by which the turning platform is supported on the bearing platform (14) are no longer in contact with the bearing platform. The insertion of the ring element (38) reduces the turning resistance of the turning platform (12), which is more suitable for heavy handicapped persons. There is also provision for rollers to be rotatably accommodated in the ring (38), the diameter of which rollers is greater than the thickness of the ring element (38), so that the ring is then operating solely as a guide retainer for the rollers. The turning resistance is then reduced still further, ensuring ease of operation for particularly heavy persons.            The new turntable (10) allows the regulation of the turning resistance in a number of stages and hence the adjustment of the resistance to the weight of the handicapped persons using the turntable in each individual case.

Inventor: NEUMAN GEORGE A
IPC: G02B1/11
Filed: 1995-10-24
Abstract: An antireflectance coating is disclosed comprising a first graded layer wherein the composition is varied throughout the thickness of the layer such that the refractive index of the graded layer varies from a low refractive index approximately matching the refractive index of the substrate at the interface of the graded layer and the substrate to a higher refractive index at the surface of the graded layer opposite the interface with the substrate, and a second substantially homogeneous layer of a composition selected to have a refractive index which is approximately the square root of the product of the higher refractive index of the graded layer and the refractive index of the incident medium at the surface of the second layer opposite the interface of the second layer with the graded layer, having an optical thickness of approximately at least one quarter of a selected design wavelength. The antireflectance properties of the coating of the present invention can be expanded to a broader range of reflected wavelengths by incorporating, between the graded layer and the second substantially homogeneous layer, an intermediate layer having a relatively high refractive index and an optical thickness of about half the design wavelength.
