Title: Remote administration of hyaluronic acid to mammals
Inventor: SCHULTZ RICHARD H
IPC: A61K/
Filed: 1987-03-31
Granted: 1993-03-09
Abstract: Mo-2817 REMOTE ADMINISTRATION OF HYALURONIC ACID TO MAMMALS              ABSTRACT OF THE DISCLOSURE The present disclosure is concerned with the discovery that hyaluronic acid, an agent well known to reduce the sequelae of trauma in mammalian joint tissue when applied directly to the traumatized tissue, will be carried to such traumatized tissue by the mammal's natural processes if applied at a site remote from the traumatized tissue.  Thus, hyaluronic acid, in any therapeutically acceptable form, can be administered by the typical remote routes including intravenous, intramuscular, subcutaneous and topical.         This makes the utilization of hyaluronic acid much more convenient and attractive.  For instance the treatment of arthritis in horse or human joints with hyaluronic acid no longer requires more difficult intra articular injections.     Mo-2817

Preferably, the wire guide is flexible and steerable for precise placement. The wire guide includes an elongated wire member having a Doppler crystal attached in longitudinal alignment at its distal end.  Electrical leads extend from the Doppler crystal along the wire member to the appropriate test equipment for measuring the fluid flow velocity in the region of the Doppler crystal.

Title: Optical waveguide arrangement for a high-voltage insulator
Inventor: MASCHEK MARTIN
IPC: H01B17/00
Filed: 1987-10-26
Granted: 1992-09-15
Abstract: ABSTRACT            In a high-voltage-conducting assembly (10), such as, for example, the current transducer arrangement for a high-voltage outdoor installation, measurement information items are transmitted via optical waveguides from high-voltage potential to ground potential.  To reduce the voltage gradi-ent along the optical waveguide, the latter is spirally conducted along an optical waveguide carrier (7) between the high-voltage side (9) and the ground potential side (5) of a high-voltage insulator (6).  The optical waveguide support (7) can be a self-supporting plastic coil (7) or the outer layer of the insulator tube of fibre-glass-reinforced plastic of the high-voltage insulator (6) or its silicon layer applied on the outside or its silicon shield tape.  In this arrangement, the surface leakage path of the optical wave-guide support is greater than 1.5-times, preferably greater than 5-times the height (h) of the high-voltage insulator (6).  The optical waveguide can be wound at a steep pitch onto the coil or arranged in a U-shaped groove of the coil or in the hollow space of a hose-shaped coil.

Title: Electron beam addressed liquid crystal light valve with input sheet conductor

Granted: 1992-04-07
Abstract: ELECTRON BEAM ADDRESSED LIQUID CRYSTAL LIGHT VALVE             WITH INPUT SHEET CONDUCTOR              ABSTRACT OF THE DISCLOSURE An electron beam addressed liquid crystal light valve (LCLV)  produces  an AC voltage across a liquid crystal layer from a single polarity electron beam, and exhibits very high resolution.  A thin layer of partially conduc-tive material is deposited on a support membrane on the electron beam side of the liquid crystal.  A conductive, electron beam permeable sheet is formed on the back of the partially conductive layer.   Electrons from the beam are absorbed by the partially conductive layer, and then flow back out to the conductive sheet to produce an AC voltage prior to the next electron beam scan.   The conductive sheet is connected in circuit with a transparent electrode which provides a voltage reference on the readout side of the liquid crystal.  The device is designed with electri-cal parameters that produce a discharge rate from the partially conductive layer fast enough to complete an AC cycle between successive electron beam scans,  but slow enough for the liquid crystal to respond and produce an image.  A separate mirror can be provided to reflect the readout  beam back through  the  liquid  crystal,  or  the conductive sheet can itself serve as a mirror.

To provide an improved extraction of the dust and thereby improve the work environment for the operating personnel involved, a dust extractor (25") having an internal space (39"? and a web stabilizing, imperforate plane (37") is mounted immediately adjacent to an intended path of travel for the creped web (1), so that the web during its transportation will place itself in a fixed position close to the imperforate plane (37"), and, at least an essential part of an entrained boundary layer of dust containing air is eliminated through suction,only to the internal space (39") . The suction is carried out at the rear and/or front edge of the extractor (25), and suitably both on the overside and underside of the web (1). Dust that does not become entrained in the boundary layers will be sucked away by at least one dust suction box (55) having a sloping suction box cover (57), and mounted under the web (1) and spaced therefrom at doctor beam (11). Preferably, an air stream, which is of sufficient force to carry the dust and caused by the suction, is made rise towards the web (1) between the dust suction box (55) and a dust extractor (271 mounted downstream of the latter.
