Patent CA-2097484-A1 (CA)
Title: Data communication system
Inventor: AVARNE SIMON A B
IPC: H04L9/32
Filed: 1993-06-01
Abstract: ABSTRACT OF THE DISCLOSURE            In a data communication system a plurality of users are equipped with respective devices for computation and authentication of message authenticators.   Each device stores a common cryptographic function;  a common secret key and a respective non-secret offset for the key. They are programmed to perform the functions of:  (i) computing and outputting an authenticator for an entered message using the cryptographic function and key combined with the respective offset;  and (ii) computing an authenticator for an entered message using the cryptographic function and key combined with any entered offset, comparing that authenticator with one received with the message and displaying a "pass" or "fail" decision.   The devices are incapable of displaying or otherwise outputting any authenticator computed using any offset other than its respective stored offset, however. In this way it can be ensured that a transmitted authenticator can act as a verifiable "signature" to a message uniquely identifying the sender.

Title: Planar porous composite structure and method for its manufacture
Inventor: SUOKAS ESA
IPC: B29C70/22
Filed: 1991-12-18
Abstract: The planar porous composite structure comprises a reinforcing structure and a matrix. The structure is formed by regular planar structures with openings, formed of continuous yarns (3, 3a, 3b), such as of knitted, woven or braided layers (1a, 1b, 1c, 1d). The pores are formed by the openings (2) of the said structures, such as by the loops of the knitted fabric or by the openings between the weft and warp yarns of a woven fabric, which are aligned by means of aligning means (7) with each other relative to the direction of the plane of the layer. The reinforcing structure is formed by the reinforcing fibres contained in the yarn (3) serving as the structural part of the structure with openings, and the matrix by the matrix material comprised in the yarn (3) of the same structure, the said matrix binding the different yarn sections of the layer (1) that surround single openings and the different layers together, stiffening simultaneously the structure.

Patent CA-2103405-A1 (CA)
Inventor: MENKEN JOHN
IPC: A61N1/37
Filed: 1993-11-18
Abstract: A capacitor charging circuit for charging a defibrillation capacitor in a constant period of time regardless of battery voltage by employing a controlled duty cycle charging technique. The defibrillation capacitor is charged in a piecemeal manner through a transistor and flyback transformer circuit. The gate of the transistor is driven by a constant frequency pulse train inverter drive signal in which voltage is conveyed to the capacitors during one-half of the full cycle of the pulse train.      The primary of the transformer is controlled by each pulse of the inverter drive signal so that the secondary of the transformer supplies current to the defibrillation capacitors during the off half cycle of the drive signal, the charge being built up in the defibrillation capacitors incrementally during the off half cycle of the inverter drive signal until the predetermined voltage is reached.

IPC: C03C17/23
Filed: 1993-12-07
Abstract: ABSTRACT OF THE DISCLOSURE   In a structure designed in particular as a glassed-in extension, the transparent enclosing surfaces are equipped with filters which selectively absorb mainly the non-visible spectral components of incident solar energy and convert them into long-wave thermal radiation, while the visible portions of the solar radiation can pass through substantially unimpeded.

Patent CA-2114803-A1 (CA)
Title: Sanitary can carriers
Inventor: ADAMI ARTHUR E
IPC: B65D71/50
Filed: 1992-08-07
Abstract: Can carriers are provided with upwardly protruding can-receiving members having oppositely paired can-receiving recesses (22) and can-stacking platforms (44). The can-receiving recesses (22) each are defined by an annular locking ring (26) which is joined to a protective inverted cup-shaped cover wall (32) sized and configured to closely correspond to the top bead (TB) of a conventional can (12). The locking ring (26) thus seats below the top bead of the can thereby removably locking the can (12) to the can carrier. A camming surface (34) downwardly and radially outwardly extends from the locking ring (26) and assists during the forcible insertion of a can into the can-receiving recess by urging the locking ring to bend and/or flex radially outwardly a sufficient amount to allow  for the diametrically larger top bead to pass thereby.  Once the top bead is seated in the can-receiving recess, the locking ring (26) will again resiliently return to its normal state.  Paired finger opening (24' or 80) are preferably provided in association with a raised pad region (60 or 84). Structurally reinforcing rib elements (86) may also be provided with the pad regions (84).

Inventor: WESTHOFF JAMES A
IPC: F16L5/10
Filed: 1994-02-03
Abstract: A molded or extruded bidirectional gasket providing a watertight seal between an opening in a manhole assembly and a pipe extending into the opening, comprises a T-shaped anchoring portion for embedment in a manhole opening.  An A-shaped pipe engagement portion is joined to the anchoring portion by a slender connecting web enabling stretching and bending of the gasket when a pipe  is  inserted.   The connecting web divides the recess into a pair of pockets on opposite sides of the web.   One of the pockets has an opening end which widens to receive water under pressure when the gasket bends to receive a pipe.  The opening of one pocket is enlarged as the other pocket is sealed.  The A-shaped portion has legs providing such recesses.   The gasket apex has a recess to locate voids therein which, in addition to enhancing mechanical softness of the gasket, also provide the ability to alter gasket compression by introducing a liquid filler thereinto.  Tapered projections near the apex wipe the external periphery of a pipe upon insertion and also contribute to the compression of the nose portion of the connector.
