Title: Highly abrasion-resistant, flexible coatings for soft substrates
Inventor: PETRMICHL RUDOLPH HUGO
IPC: G02B1/14
Filed: 1995-03-01
Granted: 2005-11-22
Abstract: An abrasion wear resistant coated substrate product is described comprising a substrate and an abrasion wear resistant coating material comprisisng carbon, hydrogen, silicon, and oxygen.  The abrasion wear resistant coating material has the properties of Nanoindentation hardness in the range of about 2 to about 5 GPa and a strain to microcracking greater than about 1 % and a transparency greater than 85 % in the visible spectrum.  The coated products of the present invention are suitable for use in optical applications such as ophthalmic lenses or laser bar code scanner windows.  In the method for making the products, the substrate is first chemically cleaned to remove contaminants.  In the second step, the substrate is inserted into a vacuum chamber, and the air in said chamber is evacuated.  In the third step, the substrate surface is bombarded with energetic ions and/or reactive species to assist in the removal of residual hydrocarbons and surface oxides, and to activate the surface. After the substrate surface has been etched, a protective, abrasion-resistant coating is deposited by plasma or ion beam deposition.  Once the chosen thickness of the coating has been achieved, the deposition process on the substrates is terminated, the vacuum chamber pressure is increased to atmospheric pressure, and the coated substrate products having improved abrasion-resistance are removed from the vacuum chamber.

Granted: 2004-11-16
Abstract: The invention relates to a method and a circuit arrangement for operating a discharge lamp.      In the preheating phase, the actual value of the load current is registered, a first time-invariant setpoint value of the load current, which corresponds to a desired actual value of a load current in the preheating phase, is formed, and a clock generator is activated, which runs freely at a frequency which is less than the resonant frequency of the load circuit when the lamp is off and is greater than the resonant frequency of the load circuit when the lamp is on. The preheating phase is terminated after a first predeterminable time period has elapsed. In the striking phase, the actual value of the load current in the load circuit is registered, a time-varying setpoint value of the load current is formed, and the clock generator is synchronized with the frequency of an inverter. The striking phase is terminated as soon as the setpoint value of the load current reaches a value at which an on-time of a half-bridge switching element is greater than. the period of the free-running clock generator. In normal operation. the actual value of the load current is registered and a second time-invariant setpoint value of the load current is formed, which setpoint value corresponds to a desired actual value of the load current in normal operation.

Abstract: A system detects cut-out of brakes on a train in a safe manner.          Each vehicle in the train has at least one truck.  Each truck has brakes which may be cut-out via a cut-out cock.  A frequency generator generates a signal at a predesignated frequency.  This signal is conveyed from a first vehicle in the train to a last vehicle in the train along a feed line and from the last vehicle to the first vehicle along a return line.  Each cut-out cock assumes an open position wherein the brakes of its truck are cut-in or a closed position wherein the brakes of its truck are cut-out.  Each cut-out cock features a switch in series with the return line that closes when its cutout cock assumes the open position or opens when its cutout cock assumes the closed position.   A frequency divider for each switch connects in parallel therewith.   When the switch is closed, the signal passes through the switch wherein division of frequency is avoided.  When the switch is open, the signal passes through the frequency divider wherein division of frequency by a preset value occurs.  A detector determines the resulting frequency of the signal returned to the first vehicle on the return line because the signal as it conducted along the return line had its frequency divided   each time it passed through one of the frequency dividers.  This enables the system to determine the number of trucks whose brakes are cut-out on the train.

Title: Delivery system for localized administration of medicaments to the upper respiratory tract
Inventor: PAN PAULINE C
IPC: A61K31/4453
Filed: 1997-01-02
Granted: 2008-10-14
Abstract: The present invention pertains to delivery systems for the localized administration of a medicament to the upper respiratory tract. The delivery system comprises: (a) a safe and effective amount of a medicament useful for treating the upper respiratory tract; (b) an ionic polysaccharide; and (c) a cross-linking agent. The present invention provides for the controlled, in situ formation of a thin, bioadhesive film which may bind to the buccal epithelial cells which form the surface of said upper respiratory tract. Said film formation occurs when the delivery system of the present invention comprising a medicament, an ionic polysaccharide and a cross-linking agent, in a pharmaceutically acceptable carrier, is slowly ingested by dissolution through salivation of the pharmaceutically acceptable carrier. By a series of cross-linking reactions, the cross-linking agent polymerizes the ionic polysaccharide to a film in the form of aggregates, which bind to the buccal epithelial cells in the upper respiratory tract. During the in situ cross-linking reaction, the medicament becomes entrapped in the bioadhesive polymer aggregate and thereafter is gradually released, i.e., becomes available through dissolution.
