Patent CA-2137582-A1 (CA)
Title: Lighting system for increasing brightness to a light guide
Inventor: DAVENPORT JOHN M
IPC: H01K1/32
Filed: 1994-12-08
Abstract: A light source includes an integral reflective coating on a portion of its envelope for reflecting light back through the source.     The light from the source is directed by a reflector toward a focus thereof at which is located an input end of a light guide. The integral reflective coating allows a half ellipsoidal reflector to be used in one embodiment without depreciable loss of light. Accordingly, a pair of light sources can be arranged with a common focus to substantially double the brightness in the light guide. Alternatively, the light sources can provide a primary and redundant arrangement, or used to provide two levels of light in another arrangement. According to another embodiment, a hemispherical reflector is used to obtain unit magnification and increase the angular range through which light may enter the light guide.

Inventor: LUDLOW M JOHN
IPC: G06F3/12
Filed: 1994-12-14
Abstract: A method of printing a job to produce a set of prints in a printing system with a print file, the print file being divided into a first buffer and a second buffer where the print file communicates with a marker. The marker employs a set of a first type of print-related information and a set of a second type of print-related information for producing the set of prints. The method includes the step of filling the first buffer with a first portion of the set of the first type of print-related information and the second buffer with the a first portion of the set of the second type of print-related information. The method further includes the step of reading, with the marker, the first portion of the set of the first typeof print-related information from the first buffer and the first portion of the set of the second type of print-related information from the second buffer. When the first portion of the set of the first type of print-related information has been read by the marker, the first buffer is filled with a second portion of the set of the first type of print-related information.

Title: Hydrogen recovery by adsorbent membranes
Inventor: ANAND MADHU
IPC: B01D53/22
Filed: 1994-12-15
Abstract: ABSTRACT      Recovery of hydrogen from hydrogen-containing gas mixtures by pressure  swing  adsorption  is  increased by utilizing  an adsorbent membrane to concentrate hydrogen in the pressure swing adsorption reject gas and recycling the resulting hydrogen-enriched stream to the feed of the pressure swing adsorption system.   Lower compression requirements are realized compared with the use of polymeric membranes for the same service because the hydrogen-enriched stream is recovered from the adsorbent membrane  as non-permeate  at  essentially  the  membrane  feed pressure.  Simultaneous permeation of carbon dioxide and methane occur in the adsorbent membrane, which can be operated at feed pressures as low as 5 psig when hydrogen is used as a sweep gas.

Title: Method and apparatus for battery charging
Inventor: REIPUR JOHN
IPC: G01R31/36
Filed: 1993-08-16
Abstract: A rechargeable battery is charged by connecting the terminals of the battery to an electrical power source. In order to avoid overcharging and undue temperature increase in the battery cell, the course of at least one charging parameter is surveyed during at least part of the process of charging the battery. This charging parameter surveyed is compared with a number of reference par-ameter courses representing idealistic or desirable processes of charging the battery for different starting states of the battery. In order to determine the starting state of the battery and thus selecting a reference parameter course, the battery may initially be test charged for a short period of time and subsequently test discharged for another short period of time. The comparisons may for example be made by means of a microprocessor, which may also select the reference course. Thereafter the process of charging the battery may be controlled so as to approximate the course of said charging parameter to the selected reference course. The in-vention also relates to a method of determining characteristic parameters of the battery which may be used to control a subse-quent charging process. Such characteristic parameters may be the capacity of the battery, the maximum charging temperature and the maximum charging voltage. The invention further relates to a battery and a battery system wherein the battery may com-prise information means for storing battery information. Such information means may for example be an electronic memory or a microprocessor.

Title: Cartridge assembly for a lyophilized compound forming a disposable portion of an injector pen and method for same
Inventor: HARRIS DALE C
IPC: A61M5/24
Filed: 1994-03-14
Abstract: A cartridge assembly (90) for holding a lyophilized product, forming a disposable portion of a pen injector (104), includes a cylindrical glass cartridge (58) adapted to receive the product, a closure cap (20), a cartridge case (76), and a plunger mechanism.  The closure cap (20) is adapted to retain an elastomeric disc seal (52) during lyophilization and includes diametrically opposed ledges (38, 40). The closure cap (20) and seal (52) are adapted to cover a neck portion of the ampule (58), the neck portion having on its end a radially extending circumferential flange (62). The ledges (38, 40) of the closure cap (20) and the flange (62) of the neck portion allow the closure cap (20) to remain open during lyophilization, oxygen purge and nitrogen overlay. An oval-shaped indentation formed on the inside of the closure cap (20) aids in snapping the closure cap (20) about the flange (62) without crimping to retain the closure cap (20) underneath the flange (62). Reconstitution of the lyophilized drug is accomplished without foaming by use of an obliquely angled connector (30) which causes the diluent to indirectly impinge on the drug. The injection pen (104) and cartridge assembly (90) cooperate such that the length of travel of the plunger rod (108) during retraction is less than the axial length of a recess (107) in the rod tip (73).
