Abstract: REMOVABLE SNAP-ON CARD STIFFENER                          ABSTRACT    A removable stiffener, which is made of titanium so that it will not be wetted by solder, consists of a thick, straight center member with wedge-shaped feet evenly spaced along its length.  A latching pin is in-cluded on one end.  The stiffener also includes flanges made of thinner stock, running the length of the stiff-ener on both sides.  These flanges strengthen the center member and hold it perpendicular to the card on which the stiffener is installed.  The stiffener requires a one-half inch wide channel on the card and a special pattern of slots.  To install the stiffener, the feet are in-serted part-way into the slots with the latching pin of the stiffener oriented near the latching slot of the card.  The card is then bent gently away from the stiff-ener while the stiffener is being pushed forward so that the latching pin and the latching slot align and engage. When the card springs back the stiffener is latched in place.

Abstract: A multiple orientation drive device (22) for use with a beverage brewing apparatus (20).  The beverage brewing apparatus is a type having a brew chamber (24) which includes a top and bottom assembly (26, 28) and an elongated brewing component (36) extending into the brew chamber.  The elongated brewing component is associated with the drive device such that it is linearly and rotatably shiftable in the brew chamber.  The linear and rotatable shifting are independently achieved by the actions of an independent linear drive assembly 50 and an independent rotary drive assembly 52.  The linear drive assembly is associated with the brewing component for linearly driving the brewing component in the brew chamber and the rotary drive assembly is associated with the brewing component for rotating the component independently of the linear drive assembly.  The present invention also includes synchronizing the linear drive assembly and rotary drive assembly to simultaneously linearly shift and rotatably shift the brewing component in the brew chamber.  A sensor assembly 48 is associated with the drive device to indicate the position of the brewing component in the brew chamber. The sensor assembly is coupled to a control device 94 which in turn is attached to the linear and rotary drive assemblies. The control device selectively energizes and deenergizes the linear and rotary drive assemblies in response to predetermined conditions defined by the control signal from the sensor assembly.

Title: Constant Voltage Fuel Cell with Improved Reactant Supply and Control System
Inventor: MERRITT ROBERT D
IPC: H01M8/04
Filed: 1993-03-12
Abstract: A method and apparatus for providing a substantially constant output voltage from a fuel cell, notwithstanding output current variations, is disclosed. The voltage and secondarily the current of the cell is determined at least periodically. The pressure of the reactant gas in the fuel cell is then regulated so substantially the nominal voltage is maintained. The temperature in the fuel cell may also be regulated to maintain the nominal output voltage. Also, a method and apparatus for minimizing the parasitic power drain in an electric power generation system is disclosed. The fuel cell is fed with a reactant gas by a compressor driven by parasitic power drawn from the fuel cell. The method is carried out by determining that the output current of the fuel cell has changed, and changing one or more or the pressure, the mass flow rate and the reactant utilization ratio of the reactant in the fuel cell, thereby changing the amount of the parasitic power drawn from the electrical power output to drive the compressor.

Title: Treatment of physiological conditions with degassed perfluorocarbon liquid
Inventor: SHAFFER THOMAS H
IPC: A61M3/00
Filed: 1993-07-14
Abstract: This invention pertains to the use of a degassed perfluorocarbon ("PFC") liquid as a method of removing gas emboli from parts of a patient's body cava. Moreover, the invention can be used as a method of imaging parts of a patient's body cava. Fur-thermore, the invention can also be used as a way of delivering biological agents to parts of a patient's body cava which contain or are surrounded by gas emboli and/or which are to be imaged. In this invention, a degassed PFC liquid is delivered to a region within the patient's body cava which contains gas emboli and/or which is to be imaged. If gas emboli are present, the degassed liquid is permitted to absorb at least a portion of the emboli. Thereafter, the emboli-containing liquid is removed from the patient or is used as an imaging agent. If gas emboli are not present, the site is imaged before the degassed liquid reaches atmospheric equilibrium. Thereafter, the liquid is removed from the patient. Moreover, by mixing a biological agent with the degassed PFC li-quid, the mixture can be used as a way of topically treating parts within a patient's body cava. Furthermore, by regulating the tem-perature of the degassed liquid, it can also be used as a way of hypo- or hyperthermically treating the patient.

Title: Method of detecting buried high conductivity objects
Inventor: MCNEILL JAMES DUNCAN
IPC: G01V3/11
Filed: 1995-05-19
Abstract: A method for surveying terrain uses transient magnetic fields transmitted from a coil in plane parallel to and above the terrain, transient voltage response from vertically spaced receiver coils coaxial with and parallel to the transmitter coil being processed to detect highly conductive objects buried in the terrain, with the ratio of the response of the coils optionally being used to estimate the depth of objects. The responses from the coils are scaled in a predetermined ratio to provide cancellation of the response from objects in a layer of terrain at a particular depth, which layer may be at the surface to remove surface responses, or beneath the surface so as to allow surface objects to be differentiated from deeper objects by providing responses of opposite polarity.

Title: Methods for providing secure access to shared information
Inventor: HAAS ZYGMUNT
IPC: G06F21/00
Filed: 1995-06-15
Abstract: The inventive methods employ symmetric encryption with first and second keys to provide secure access to information accessible to be shared among a dynamically changing set of authorized users on a network having a server.  A single copy of the information, encrypted with the first key of the server, is stored in a location accessible to all network users.  The second key is a private key of an authorized user and is used by the server to encrypt the first key.          The encrypted first key is then stored by the server at a storage location accessible by the authorized user.   The user accesses the storage location, obtains the encrypted first key, and uses his private second key to decrypt and thereby recover the first key.  The user then decrypts the stored information using the recovered first key.
Patent CA-2153535-A1 (CA)
Inventor: CASTNER GLENN CLARK
IPC: B29C51/32
Filed: 1995-07-10
Abstract: The invention relates to a mold apparatus and a process for forming a lid latching mechanism in a thermoplastic container.  The lid latching mechanism features a large, trapezoidally-shaped opening hole.  The trapezoidal shape has been found to reduce the amount of tearing that can occur along the edges of an opening formed during the thermoforming process.  The opening is created by the engagement between a fixed shear key mounted in a first mold member and a movable shear key which has a trapezoidally-shaped cutting surface and is mounted in a second mold member.  The movable key travels along an inclined path as the mold members close on a preheated thermoplastic sheet to form a container.
