Patent CA-2093883-A1 (CA)
Title: Cab window security device
Inventor: BENNINGER KEITH G
IPC: B60J1/20
Filed: 1993-04-13
Abstract: 13 Title: CAB WINDOW SECURITY DEVICE The sliding windows in the back of the cab of a pick-up truck are vulnerable to break-ins because a thief can pry the panes apart using friction from the pressure of his hand on the panes. The normal clamp is by-passed during this type of break-in. An adjustable-length strut is formed with hook-shaped ends. The hook-ends engage around the outer edges of the sliding panes. A catch on the strut comprises a peg which is spring-loaded into engagement with a notch. When the driver presses the peg, he thereby disengages the catch on the strut, allowing the strut to be set to the length where the hook ends can be engaged to and disengaged from the edges of the panes.
Patent CA-2100929-A1 (CA)
Inventor: BRAIN ARCHIBALD I J
IPC: A61B5/00
Filed: 1993-07-20
Abstract: A reflectance oximeter is so mounted to the upstream or proximal side of a laryngeal mask as to face the posterior wall of the pharynx when the laryngeal mask has been positioned to perform its function of sealed, exclusive airway communication with the laryngeal inlet.  Thus positioned, radiation from the oximeter can utilize local back-bone features as a reflector, for two-way passage of the radiation through tissue which characterizes the posterior wall of the pharynx.  Moreover, the oximeter-observation region is within the body, so that ambient light has no degrading effect, and changes in oxygen saturation will be detected earlier than by use of any peripherally placed oximeter probe.
Patent CA-2103146-A1 (CA)
Title: Arrangement for forming a sealed electrical splice
Inventor: DELALLE JACQUES
IPC: H02G15/04
Filed: 1992-06-05
Abstract: An arrangement for forming a stub splice between two or more elongate electrical conductors comprises a hollow electrical connector and a hollow cap containing a quantity of gel. In use, the cap engages an open end of the connector, and the elongate conductors extend through the open end of the connector and through one or more apertures contained in the cap. Once the cap is engaged, the gel is compressed and the splice is sealed against moisture ingress. In order to ensure that the gel is maintained under compression, the cap may optionally contain a quantity of non-gelatinous resiliently compressible material which substantially compensates for any changes in the volume of gel.

Title: Disposable dental matrix retainer clamp
Inventor: DICKIE ROBERT G
IPC: A61C5/12
Filed: 1992-03-09
Abstract: A dental matrix retainer package (10) includes a plastic matrix retainer clamp which permits a matrix band (22) to be un-locked from its lightened position over a tooth without releasing the matrix band from the clamp entirely, permits a matrix band to be swiveled to accommodate different mouth quadrants with removal for reorientation, permits rapid retraction of a matrix band from a tooth, and permits careful tightening of a matrix band over a tooth in order to avoid the possibility of overtightening. The package is designed so that it must be entirely disposed of after use on a patient, thereby providing maximum assurance against cross contamination.

Title: Cassette tape player having circuit for detecting reverse rotation of tape-up reel
Inventor: TARPLEY GERALD W JR
IPC: G11B15/54
Filed: 1993-10-14
Abstract: Abstract A system for preventing improper tape feed in a cassette tape player uses pulse width measurements from the take-up reel output signal to sense normal or aberrant tape feeding conditions.  The pulse width of the output signal is compared with a predetermined range of pulse widths associated with normal tape operation.  The tape player either stops or reverses the rotation of the take-up reel if the pulse width of the output signal is outside of the predetermined range, denoting an aberrant tape feeding condition.

IPC: A61G7/08
Filed: 1994-06-28
Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus and a method for transporting a health care patient is disclosed. The apparatus comprises a wheeled undercarriage having a base and a load bearing surface located above the base. A health care patient conveyance such as an infant transport incubator or a stretcher is removably affixed to the load bearing surface. The base of the wheeled undercarriage is provided with an electric winch that is connected to a rechargeable storage battery for providing drive power. Controls associated with the wheeled undercarriage permit an operator to selectively operate the winch in either direction of rotation so that the apparatus can be towed onto or off from an ambulance or the like. The apparatus can also be used for retrieving accident victims frominaccessible places such as the steep incline of a road embankment. The advantage is that arduous lifting is eliminated and patient security is enhanced.

Title: Process for preparation for alkanolamine, catalyst used in the process and process for preparation of the catalyst
Inventor: MORIYA ATUSI
IPC: B01J23/10
Filed: 1994-10-31
Abstract: Abstract of the Disclosure A process is provided which comprises using a catalyst comprises a rare earth element supported on an inorganic heat-resisting carrier, when a monoethanolamine is selectively prepared by reacting an alkylene oxide with ammonia in a liquid phase.  This catalyst has excel-lent monoalkanolamine selectivity and heat resistance; and therefore, even when the ratio of ammonia to the alkylene oxide is lower compared with cases where other catalysts are used, an equal or more amount of the mono-alkanolamine can be formed, and thus the recovery cost of the unreacted ammonia is reduced. Further, since the total amount of the feed raw materials is reduced, appa-ratuses for the reaction system and recovery system can be made smaller, and thus the cost of equipment is reduced.

Title: Medical instrument with dual action drive
Inventor: LYONS WILLIAM G III
IPC: A61B17/28
Filed: 1993-05-11
Abstract: A medical instrument including a tubular extension (1c) within which and to which two movable end effectors (60a, 60b), such as jaw members, are rotatably attached by a pivot. The proximal end of each end effector is pivotally attached to and butts against a drive surface of its respective arm of a dual action drive member (30) also located within the tubular extension. As the dual action drive member (30) is moved proximally or distally within the tubular extension, the distal ends of the end effectors rotate (60a, 60b) or counter rotate about the pivot (80) in opposition to one another. The dual action drive member paired arms have end surfaces (40a, 40b) which transfer, to the end effectors, the force required to rotate the end effectors toward one another, thereby reducing the shear force applied to pivot posts on the arms used to open the jaws.

Filed: 1995-07-04
Abstract: A signal level measuring apparatus which measures a level of a satellite signal from a geostationary satellite as received by a receiving antenna and provides an output to determine whether the antenna is correctly directed toward the satellite.  The apparatus is disposed between a converter associated with the antenna for converting the satellite signal into an IF signal and a tuner for demodulating the IF signal.  The apparatus includes distributing means for divid-ing the IF signal from an input terminal of the apparatus into two output signals.  One of the output signals is coupled to an output terminal of the apparatus, which, in turn, is coupled to the tuner.  The other output signal is applied to level detecting means.  An output from the level detecting means is compared in comparing means with a reference signal.

The method may include: a) the first user identifying to an E-mail transmitter that a transmission of such data is one which is to be certified; b) the first user being prompted to indicate whether or not information concerning the receiver and second user of the transmission are correct; c) the first user transferring the data to the  E-mail transmitter and verifying that the information is correct; d) transmitting the data from the E-mail transmitter to the E-mail receiver via a central processing unit; e) indicating to the E-mail receiver that the transmission is a certified transmission and that it is to be opened only by a named second user, and prompting the second user to confirm that the certified transmission may be accepted and opened; and f) storing a record of the transmission. The record, which is a certified record, may include identifications of the first and second users, dates and times of sending and opening of the transmission, and a copy of the data.  Optionally, the second user may be permitted to respond to the first user, and the response also forms a part of the certified record.  The transmission or the response may be an authorization to remove monies from a bank account.
