Abstract: A safe-deposit box uses a lock including a tongue, a first mechanical device, a second mechanical device, a solenoid, a control unit and a keypad.  A renter's key drives the first mechanical device from a first position to a second position to actuate the control unit.  The solenoid is in a first position to retain the first mechanical device in the second position.  A code is input through the keypad to the control unit to drive the solenoid from the first position to a second position to allow movement of the mechanical device from the second position to a third position to retract the tongue.  A clerk's key can drive the second mechanical device from a first position to a second position to drive the solenoid from the first position to the second position and turn off the control unit.  If the code is forgotten, the second mechanical device is driven from the second position back to the first position to retain the solenoid in the second position to allow movement of the first mechanical device from the first position to the third position.  If the renter fails to pay rent for the safe, the second mechanical device is driven from the second position through the first position to a third position to drive the solenoid back to the first position to prevent movement of the first mechanical device from the first position to the third position.

Title: Pure 3r-3'r stereoisomer of zeaxanthin for treating macular degeneration in humans
Inventor: GARNETT KEVIN M
IPC: A23L1/30
Filed: 1996-10-28
Granted: 2001-02-27
Abstract: Methods and formulations are disclosed for making and purifying the 3R-3'R stereoisomer of zeaxanthin as a sole detectable isomer, in any desired quantity, for use as a drug or vitamin by humans. Zeaxanthin, a yellowish pigment which is naturally present in macular cells in the center of the human retina, absorbs blue and near-ultraviolet light radiation, thereby protecting retinal cells against phototoxic damage. Zeaxanthin preparations which contain only the desired 3R-3'R stereoisomer can be produced by a strain of Flavobacterium mul tivorum cells (ATCC accession number 55238). These cells (and other cells transformed with their zeaxanthin-producing genes) do not create any detectable quantities of the undesired S-S or S-R isomers of zeaxanthin, and they do not synthesize significant quantities of other carotenoids which might compete against zeaxanthin for alimentary uptake after oral ingestion. After synthesis using microbial fermentation, the zeaxanthin can be concentrated to about 5 to 20% by simple and inexpensive steps such as solvent extraction. It can also be purified to much higher levels by other methods, if desired. The pure R-R isomer can be taken orally, either as a therapeutic drug by patients suffering from macular degeneration, or as a vitamin or nutritional supplement by anyone who wants to reduce his or her risk of suffering from age-related macular degeneration, which is widespread among people over the age of about 50 or 60. Extraction solvents, stabilizing agents, and convenient formulations for oral ingestion (such as mixed with vegetable oil and encapsulated, or used as a margarine or food additive) are also disclosed.

Granted: 2005-10-18
Abstract: The present invention relates to an improved counter weight door of the type for use at an opening in a wall of a building. The counter weight door includes door panels comprising two or more standard sized overhead door panel sections which are joined together by a pair of J-shaped channel members. A  pair of hinge connectors have be mounted side by side at each side of each door panel and adjacent the joint between adjacent top and bottom edges of adjacent door panels The axle of the guide rail follower has been lengthened to allow it to extend through an elongate tubular member on each of the pair of hinge connectors.  This gives each pivot connection additional strength and yet allows standard overhead door hinges to be used. Improved pulley mounts allow the pulleys to be easily arranged and secured above and to the side of the opening in the wall, and lie substantially in the plane of the door. Mounting the pulleys directly on the guide rails helps the installer mount the pulleys such that their axis of rotation lies substantially perpendicular to the plane of the door. This helps ensure smooth operation of the pulleys as the door is opened and closed.

Abstract: A method for recovering an outgoing data signal from an incoming signal received over a transmission network is disclosed. The method provides for preparing a bit error rate (BER) map for a data regenerator, determining, on the BER map, an optimal operation point for a provisioned BERprov value, and monitoring the data regenerator to function in the optimal operation point for providing a regenerated data signal. In addition, the errors in the regenerated data signal may be further corrected using current forward error correction circuitry. To prepare a BER map, the data regenerator operates in an error mapping mode, wherein the incoming signal is decoded using a slicing level Vi and a phase shifted clock signal CLj. Each value BERi,j is measured over a preset period of time Tprov for a pair Vi,~j and stored in a memory. The BER maps may be prepared once a day or at any other suitable interval. In the optimization mode, the operation point for the regenerator is calculated for a BER contour corresponding to the provisioned BERprov, for detemining the coordinates Vopt and ~opt. In the data regeneration mode, the regenerated data signal is obtained using Vopt and ~opt.
