Title: Gas generator
Inventor: OLOMAN COLIN
IPC: F16N11/10
Filed: 1992-04-24
Abstract: A gas generator particularly useful as a component in a fluid dispensing apparatus. The generator produces gas at a relatively constant rate and, in a preferred embodiment, at a rate which has a reduced dependence on ambient temperature. The gas generator comprises a liquid and a solid composition. The solid composition may be a first reagent dispersed in an inert solid or may consist essentially of the first reagent. In either case the solid composition, following contact with the liquid, reacts to generate a gas for at least about 20 hours during which at any elapsed time, t, of the reaction V=Y't m where V = volume of gas produced as measured at constant temperature and pressure; Y = a rate constant related to the rate of reaction; m = any value between about 0.5 to about 1.3 when the temperature is constant.  Preferably, the reaction has an m value within the foregoing range when the temperature is constant at some value within the range of about -30 °C to about 40 °C. The reaction is also preferably selected such that the apparent activation energy is no greater than about 40 kJ/mole, and preferably no greater than about 30 kJ/mole.

Abstract: CURRENT LIMITING SOLENOID DRIVER                ABSTRACT OF THE DISCLOSURE           A solenoid driver (28, 114, 151) applies an actuation current to a solenoid (14) for a predetermined period  and a  lower holding  current thereafter.   A switching device  (34,  116,  152)  pulses the applied current within upper and lower limits to maintain the actuation and holding current amplitudes, the pulses being  integrated  by  solenoid  inductance  into  a substantially steady-state current.  A multiprocessing unit (18) determines the amplitudes of solenoid current. A signal representative of desired current amplitudes is compared  with  a  signal  representative  of  measured solenoid current,  and a signal representative of the difference therebetween is used to control the switching device  (34,  116,  152).   Voltage developed across a resistor (36) in series with the solenoid (14) is input to a differential amplifier (40) having connected to its output a peak detector (42) that mimics the decay rate of   current   in  the   solenoid   (14),   the  signal representative  of  measured  solenoid  current  being obtained from the peak detector (42).  Power dissipation by the solenoid driver (28, 114, 151) is minimal, and the latter is capable of withstanding a continuous short to a source of electric current.  The output of the peak detector (42) is monitored by the microprocessing unit (18) for the detection and logging of faults.

Title: Apparatus and methods for electroporation amd electrofusion
Inventor: SCHMUKLER ROBERT E
IPC: C12N15/02
Filed: 1992-07-21
Abstract: An insulating film (20) in a container has pores (28) whose diameter is smaller than the diameter of a first type of cells (60) in the container. The first type of cells are trapped in the pores, so that when an electric field is applied to the container, electro-poration of the first cells occurs. If a second type of cells (70), smaller than the first type of cells, are also trapped in the pores, electrofusion will occur between the first and second types of cells trapped in the same pores.

Patent CA-2118344-A1 (CA)
Inventor: MAHONEY JAMES V
IPC: G06V30/40
Filed: 1994-10-18
Abstract: Image data define an image that shows an input graphical representation whose configuration represents information. The image can show a sketch, for example. The image data are used to obtain category data indicating a category of graphical representations. For example, the category data could indicate any of X-Y graph, directed graph, undirected graph, bar graph, pie chart, line graph, scatter plot, circuit diagram, flow chart, Venn diagram, state-transition diagram, tree, table, matrix, or array. The category data could also indicate a specific category within a generic category such as bar graph or pie chart. The category data can be obtained by determining whether the graphical representation satisfies a constraint on each category. Each category's constraint may be applied to parts of the input image that meet a feature candidate criterion, which may be different for each specific category in a generic category, even though the feature candidates must satisfy another constraint that is the same for all specific categories in the generic category. The category data are then used to obtain content data indicating information represented by the input graphical representation's configuration, and an output image is obtained with an output graphical representation, with a configuration representing the information indicated by the content data. The output graphical representation can be more precisely formed than the input graphical representation. The output graphical representation can be in the same generic category as the input graphical representation, but possibly in a different specific category, or it can be in a different generic category.

Title: An arrangement for establishing electrical contact in joints, and a method of producing the arrangement
Inventor: LEEB KARL-ERIK
IPC: H01R4/24
Filed: 1994-03-22
Abstract: The present invention relates to an arrangement for establishing electrical contact in joints, and to a method of producing the arrangement. The arrangement comprises an electric contact making device which is enclosed in a joint between two metal surfaces between which electrical contact shall be established, wherein the joint and the contact making device are held together and protected by plastic material. The arrangement is produced by applying pressure to the joint so that the surface penetrating devices of the contact making device will spring, and by converting the plastic material from a fluid state to a solid state while maintaining the pressure, so that the resilient biassing effect of the surface penetrating devices against the metal surfaces will be made permanent in the arrangement.

Title: Lock-Out Mechanism for Empty/Load Changeover Valve
Inventor: PASEK STANLEY J
IPC: B60T8/18
Filed: 1994-03-22
Abstract: A lock-out assembly having a latching mechanism by which means a plunger may be manually depressed and latched in a lock-out position in which a lock pin is pre-set by engagement with an actuator rod of an empty/load valve or the like, so that in response to axial extension of the actuator rod sufficient to align a locking groove in the actuator  rod  with  the  lock  pin,  locking engagement therebetween will occur to limit further axial extension of the actuator rod, without any further action on the part of the operator.  Automatic disengagement of the lock pin from the locking groove of the actuator rod occurs in response to axial retraction of the actuator rod,  by effecting disengagement of the latching mechanism to allow a return spring to reset the plunger.

IPC: G11B20/18
Filed: 1994-10-21
Abstract: An improved storage device, such as a disk drive, is disclosed for use in an array of drives.  Each drive has logic and Exclusive Or calculation means. Data to be written is sent to the target disk drive from the host computer undera new command that instructs the target drive to generate part of the new parity, and may also identify the parity drive.  The target device reads the old data from it's media, generates a parity syndrome, stores the new data and then initiates communication with the identified parity drive, instructing the paritydrive to read the old parity and generate the new parity information from the parity syndrome and the old parity.  The parity drive, after generating the new parity, writes the new parity onto it's media, all without further host or host I/O action.

Title: Electronic combination lock with closure and locking verification
Inventor: HAMILTON JAMES E
IPC: E05B47/00
Filed: 1995-02-03
Abstract: A lock is described which has the capability to generate or encrypt a close number which is then displayed to the operator of the lock to be used to verify the locking of the lock. This number must be reported to a central dispatch operation where it is compared with a number similarly generated using identical starting values and an identical encryption algorithm. Comparison of the two numbers, resulting in a compare equal will indicate that the lock has been locked since the lock encryption operation is dependent upon the repowering of the lock. The lock is repowered after it has been opened by rotation of the dial which will extend the bolt and through the rotation of the dial drive a stepper motor/generator to provide electrical power to the lock.
