Patent CA-2115671-A1 (CA)
Inventor: ZINK JEFFREY I
IPC: G01N33/58
Filed: 1992-08-12
Abstract: An active biological material encapsulated in a glass is formed using a sol-gel process. A metal alkoxide is mixed with water (12) and exposed to ultrasonic energy at pH <= 2 to form a single phase solution which is then buffered to a pH between about 5 and 7 (17). The buffered solution is then mixed with the active biological material (20) and the resultant gel (21) is aged (22) and dried (24). The dried product is a transparent po-rous glass with substantially all of the added active biological material encapsulated therein (26), the biological material re-taining a high level of activity.
Patent CA-2117290-A1 (CA)
Inventor: MILLER MARK
IPC: E21B47/01
Filed: 1994-05-26
Abstract: The apparatus disclosed is a type of downhole pressure gauge to be used to measure and record pressure information about oil and gas wells. The apparatus measures flunctuations in pressure by means of a mechanical pressure sensitive device, such as a Bourdon tube, and records and stores this information by converting mechanical movement, associated with pressure changes as detected by the mechanical pressure sensitive device, into corresponding voltage changes across a potentiometer which are stored in an electronic memory board. The change in voltage over time corresponds to the change in well pressure over time, thereby providing important information to the well operator. Also disclosed is a method for measuring well pressure by means of combining a mechanical pressure sensitive device with an electrical system and an electronic memory board for storing the measurements. Also disclosed is a kit, whereby an existing downhole mechanical pressure gauge can be converted to a mechanical/electrical combination by the replacement of certain parts.

Title: Registration process
Inventor: LANDECK HARRY A
IPC: B31B19/74
Filed: 1994-06-21
Abstract: REGISTRATION PROCESS     ABSTRACT OF THE DISCLOSURE      The present invention features a high-speed registration system for the manufacture of plastic bags. The system has a registration apparatus that senses the leading and trailing edge of each sinusoidally-shaped tie pattern from a continuous web.  Each sinusoidally-shaped tie is associated with an individual bag entity and, therefore, represents a midway point for each bag to be cut from the continuous web.  The leading and trailing edge of each sinusoidally-shaped tie, therefore, is used to determine the center line of each bag.  A plurality of center line determinations are averaged upstream of the sizing apparatus.  When a detected entity finally reaches the downstream sizing apparatus, the cutting of the individual bag unit from the web is accomplished about an accurate, but "floating", center line.

Title: Method for activating an occupant restraint in a vehicle
Inventor: HUANG MATTHEW
IPC: B60R21/01
Filed: 1995-01-11
Abstract: A method for activating an impact responsive device in a passenger vehicle is provided wherein a single point sensing device senses deceleration of the vehicle during an impact event.  The sensed deceleration is integrated to determine velocity of the vehicle.  The velocity is then integrated to determine displacement of the vehicle.  The difference between the deceleration and a preselected deceleration bias is integrated over displacement to provide a residual energy density.  This residual energy density is compared to the threshold residual energy density from a predefined activation threshold line which is selected based on the impact characteristics of the vehicle.  When the residual energy density is equal to or exceeds the activation threshold line, the impact responsive device is activated.

Title: Method for generating filtered noise signal and broadband signal having reduced dynamic range in mass spectrometry
Inventor: KELLEY PAUL E
IPC: H01J49/42
Filed: 1993-07-28
Abstract: A method for generating a filtered noise signal, which includes the steps of generating a broadband signal having opti-mized (reduced or minimized) dynamic range, and filtering the broadband signal in a notch filter (35B) to generate a broadband signal whose frequency-amplitude spectrum has one or more notches. In preferred embodiments, the filtered noise signal is a vol-tage signal suitable for application to an ion trap (16) during a mass spectrometry operation. The invention enables rapid genera-tion of different filtered noise signals by filtering a single, optimized broadband signal using a set of different notch filters, each having a simple, easily implementable design. Digital values indicative of the amplitude, frequency, and phase of each sinusoidal (or other periodic) component of an optimized broadband signal can be iteratively generated by a digital computer in accordance with the invention, and the digital values can then be processed to generate an analog version of the optimized broadband signal.

Inventor: DOSHI BHARAT T
IPC: H04L29/06
Filed: 1995-03-28
Abstract: The retransmission of signaling messages that data terminals (e.g., modems) might exchange prior to exchanging user data is controlled by arranging a data terminal that receives multiple copies of the same signaling message so that it saves only the first copy thereof, but transmits a response to the sending terminal following receipt of each such copy. The sending terminal terminates its transmission of the signaling message upon receipt of a response from the receiving terminal. The inventive procedure is especially advantageous for controlling theretransmission of signaling messages during a n-way handshake between two terminals.
