Patent CA-2015311-A1 (CA)
Title: Ergonomic seat
Inventor: DEGEN HUGO
IPC: A47C3/026
Filed: 1990-04-24
Abstract: Abstract The foot bearing the seat surface of a seat is divided at a distance of 20-30cm from the seat surface. Between the mutually facing end faces of the two foot parts  (5a,5b)  a rubber cushion  (9) is arranged,  the circumferential area of which is widened to form a brake ring (11).  The elastic restoring force, working counter to the  inclination of the seat,  of this  cushion is reinforced by  two  further  cushions  (16,17)  arranged within the foot parts (5a,5b).  By means of the suitable arrangement of sliding elements with low friction (T1-T3),  the mutual rotation between the two foot parts (5a,5b) is ensured.        Thanks to this construction, the seat surface can be swiveled in a tumbling manner in such a way that every point  of  said  seat  surface  moves  on  an  imaginary spherical surface and thanks to the mentioned elastic restoring force, the seat part always returns automati-cally  to  its  initial  position.    When  the  seat  is inclined, the then undesired rotation of the upper seat part (5a) is prohibited by the friction between its edge area (R) and the compressed brake ring (11).            (Fig. 3)

Patent CA-2021386-A1 (CA)
Inventor: OLSEN GENE E
IPC: E04G17/00
Filed: 1990-07-17
Abstract: A safety anchor including a pair of rectangular plates connected by a spring-loaded hinge assembly which normally biases the plates toward one another is a completely folded configuration. Each plate defines an aperture aligned with the opposing aperture when the plates are completely folded together. A double locking safety hook may be clipped through the apertures, and prevents the plates from being unfolded. Each plate includes a retention post fixedly attached thereto and extending outwardly beyond the rear edge of the associated plate. Each retention post has an enlarged head with two flat surfaces. The flat surfaces may be aligned with the slot in the beam and inserted therethrough into a recessed cavity when the plates are completely unfolded. When the plates are then folded together, the retention posts rotate relative to the slot and the enlarged heads become engagingly retained within the recessed cavity and behind the narrower slot. The spaced-apart retention posts prevent rotation or rocking of the safety anchor. During a fall, the plates of the safety anchor will cam against the face of the beam, and the hinge assembly will bear no load. Once the safety link is detached, the safety anchor may be removed and remounted on another beam using only one hand. The safety anchor is particularly suited for use with horizontal slotted beams and associated components utilized in erecting concrete pouring forms of the type referred to as "flying forms".

Title: Fastener for carbon fibre structure
Inventor: PEGG LESLIE
IPC: F16B33/00
Filed: 1990-10-26
Abstract: A lightning resistant composite structure, particularly for aircraft, in which a composite skin panel, for example of carbon fibre, is attached to an inner composite structure by one or more lightning resistant fastener assemblies. The fastener assembly comprises a nut and bolt, the bolt being in good conductive contact with a conductive sleeve engaging the skin panel and a non-conductive sleeve engaging the inner structure. The nut is contained within a capped nut assembly located to the undersurface of the inner structure.      The non-conductive sleeve and the capped nut assembly isolate the inner structure from the effects of lightning strike, the conductive sleeve providing a high quality conductive interface between the bolt and the skin panel.      By this means adverse penetration of lightning current into the inner structure is prevented.

Filed: 1990-11-22
Abstract: ABSTRACT OF THE DISCLOSURE        ELECTRICAL SWITCHGEAR HAVING AN INSERTABLE             AND RETRACTABLE APPARATUS RACK     A switchgear features insertable and retractable apparatus racks, which are to be connected by means of break-contact devices to current supply conductors (busbars) and to outgoing conductors.  The busbars are configured to lie one behind the other in the moving direction during insertion and retraction.  Both break-contact configurations are simultaneously actuated by means of a mutual driving arrangement consisting, for example, of a shaft, pinions and gear racks.  The result is that when the break-contact configurations are closed, the apparatus rack is mechanically blocked in a reliable manner so that it cannot become displaced.

Inventor: LAPPI DOUGLAS A
IPC: A61K47/48
Filed: 1990-04-26
Abstract: The invention provides a conjugate comprising FGF or other polypeptide reactive with an FGF receptor, and a cytotoxic agent. The cytotoxic agent can be a ribosome-inactivating protein (RIP), such as saporin, although other cytotoxic agents can also be advantageously used. The cytotoxic agent can be attached to FGF through a chemical bond or the composition can be prepared as a chimera, using techniques of recombinant DNA. The conjugate can be used to treat FGF-mediated pathophysiological conditions by specifically targeting cells having FGF receptors and inhibiting proliferation of or causing death of the cells. Additionally, the conjugate can be used to target cytotoxic agents into cells having FGF receptors, and to inhibit the proliferation of such cells. A method of purifying the conjugate on an immobilized heparin column is also provided.

Patent CA-2055987-A1 (CA)
Inventor: KESSLER WILLIAM K
IPC: H04M1/57
Filed: 1991-11-21
Abstract: Telephone call identification service that safeguards the privacy of an originating station (calling party), while providing useful identifying information to a destination station (called party), is achieved by an encryption process. The encryption process includes combining the originating number with the telephone number of the destination station to form a message. Thereafter, the message is encrypted using the Data Encryption Standard (DES) or the Rivest, Shamir, Adleman (RSA) encryption algolithm to form ciphertext which is transmitted to the destination station. Using either encryption process, the ciphertext is reversible. A telephone switching office, preferably equipped with an electronic program-controlled switching system, executes the encryption algorithm and safeguards the keys used for encryption and decryption. When reversibility of the ciphertext isdeemed to be undesirable, the telephone switching office uses modulo n processing of the ciphertext to render it non-reversible.

Title: Combination beverage container resealing assembly and drinking spout
Inventor: FLATHER DAVID J M
IPC: B65D47/14
Filed: 1992-02-20
Abstract: COMBINATION BEVERAGE CONTAINER          RESEALING ASSEMBLY AND DRINKING SPOUT          Abstract The invention's preferred use is an improvement to the 355 ml or larger aluminum beverage can.  The invention is placed over the top of the opened or unopened aluminum beverage can by a manual "snap in place" process.  Similarly, the secondary lid located on the protruding drinking spout is easily affixed using the same "press on" motion which forms both a mechanical and frictional bond.  The invention provides an effective air-tight seal to prevent the loss of fluid or carbonation from the aluminum beverage can, as well as preventing the entry of foreign materials into the opened aluminum can.  In addition, the invention prevents spillage of the beverage or fluid within the aluminum can when attached properly.  Furthermore, the secondary protruding spout and lid assembly provide a one hand operation of holding the aluminum can as well as opening or closing the secondary lid which allows convenient spill-free consumption of the beverage while the consumer is in motion, such as walking or riding in an automobile.
