Patent CA-2027389-A1 (CA)
Inventor: CORSMEIER ROBERT J
IPC: F02C3/073
Filed: 1990-10-11
Abstract: ABSTRACT OF THE DISCLOSURE     A  clearance  control  apparatus  has  a  positioning mechanism for controlling clearance between rotor blade tips and a shroud segment of a gas turbine engine casing, and a rotatable lever for actuating the mechanism.  The positioning mechanism  is  supported by a  casing boss, coupled to the shroud segment, and actuatable for moving the shroud segment toward and away from the rotor blade tips to reach a position at which a desired clearance is established.  The mechanism includes a shaft and a pair of cam elements.   The shaft is mounted by the boss for radial movement toward and away from the rotor axis and coupled at its inner end to the shroud segment.  An outer cam element is attached to the outer end of the shaft and spaced outwardly from the boss.  An inner cam element is attached to an end of the lever mounted to the boss for rotational movement  about  a  longitudinal  axis  of the shaft.  The inner cam element is located between an outer end of the boss and the outer cam element and engaged with the outer cam element such that rotation of the inner cam element with rotation of the lever produces radial movement of the outer cam element and of the shaft and shroud segment therewith toward and away from the rotor blade tips.

Title: Carpet pads having pressure sensitive adhesive
Inventor: HOOPENGARDNER MERLE R
IPC: A47G27/00
Filed: 1990-12-12
Abstract: 192/Canada CARPET PADS HAVING PRESSURE SENSITIVE ADHESIVE     Abstract of the Disclosure A carpet pad has pressure sensitive adhesive preapplied on one or both surfaces, for retaining the pad and a carpet in place on a floor by adhesion without the need for stretching.  The pad or cushion in one embodiment has a film or sealant on the surfaces of the pad, with pressure sensitive adhesive on at least one of the sealed surfaces for adhering to floor surface or the underside of a carpet.  In another embodiment, the pressure sensitive adhesive is a hot melt adhesive, not water-based.  The hot melt pressure sensitive adhesive is applied to an uncoated porous padding surface which would be unsuitable for a water-based pressure sensitive adhesive due to excessive wicking-in of such an adhesive.  An optional scrim webbing may be applied over the pressure sensitive adhesive, in either embodiment.  The scrim webbing adds dimensional stability and also enables the carpet pad to be moved around on a floor or against another surface without sticking, prior to the application of pressure.

Title: Adjusting press platen clearance
Inventor: FERGUSON ANDREW
IPC: B30B1/32
Filed: 1991-01-22
Abstract: ABSTRACT OF THE DISCLOSURE .In a press having a lower stationary platen, an upper movable platen, a hydraulic ram that travels with the upper platen, light-duty cylindersthat position the upper platen, and a gate mechanism that closes above the ram to permit the ram to drive the upper platen during compression phases of operation, method and apparatus for adjusting the clearance between the upper and lower platens. A member of cylindrical spacers can be distributed, as desired, between an upper end of the ram and a spacer retaining mechanism located above the gate mechanism. The spacers are shaped to vertically interlock to form a stable stack atop the ram. The retaining mechanism extends downwardly from an upper cross-head of the press and is received in the interior of the stack of spacers. The retaining mechanism has spring-biased locking members that can locate below an internal lip of any spacer. To remove spacers, the ram is raised until all spacers seated on the ram interlock with any spacers supported by the retaining mechanism. All spacers are then raised until the locking members engage a lowermost one of the spacers to be removed. The ram is then simply lowered, retaining the a desired number of spacers. A similar procedure is followed to add one or more spacers, but a hydraulic cylinder is actuated to retract the locking members to release the spacers.

Abstract: Abstract of the Disclosure Superconducting tapes having an inner laminate comprised of a parent-metal layer, a superconductive alloy layer on the parent-metal, a reactive-metal layer, and an outer laminate soldered thereon are joined in a superconducting joint by the method of this invention.  The outer laminate is removed to form exposed sections, and the tapes are positioned so that the exposed sections are in contact.  A melt zone within the exposed sections where the exposed sections are in contact is melted.  The melt zone is at least large enough to provide sufficient parent-metal, superconductive alloy, and reactive-metal to form a melt that resolidifies as a continuous precipitate of the superconductive alloy.  The melt resolidifies as a continuous precipitate of the superconductive alloy that is continuous with the superconductive alloy on the superconducting tape. Optionally, sections of the outer laminate material corresponding to the size of the exposed sections are bonded to the outermost surfaces of the joined exposed sections.

Abstract: PIPELINED CRYPTOGRAPHY PROCESSOR AND METHOD FOR ITS USE IN COMMUNICATION NETWORKS                   ABSTRACT OF THE DISCLOSURE           Cryptographic apparatus,  and a related method for its operation,  for in-line encryption and decryp-tion of data packets transmitted in a communication network. A full-duplex cryptographic processor is posi-tioned between two in-line processing entities of a net-work architecture. For example, in a fiber distributed data interface (FDDI)  network, the processor is posi-tioned between a media access control  (MAC)  sublayer and a ring memory controller (RMC).  Incoming informa-tion packets are analyzed to decide whether or not they contain encrypted data and, if they do, are subject to decryption before forwarding. Outbound information pac-kets have their data portions encrypted if called for, and are usually forwarded toward the network communica-tion medium.  Cryptographic processing in both direc-tions is performed in real time as each packet is streamed through the processor. The processing of out-bound information packets includes using optional data paths for looping of the processed information back in a reverse direction, to permit the host system to per-form local encryption or decryption for various pur-poses.

Title: Synchronous adjusting device for office chairs or the like
Inventor: ROERICHT HANS
IPC: A47C1/032
Filed: 1990-12-21
Abstract: A synchronous adjusting device is proposed as a chair mechanism for office chairs, seat furniture or the like, which is constructed extremely simply and with few mechanical means and which, if appropriate, can do without additional force accumulators. At the same time, the restoring movement of the back part wall take place as a function of the weight of the user, a restoring moment occurring with the increase in inclination of the backrest. For this, the back part (7) is mounted rotatably relative to the seat part (5) at a distance in height. The leaning force (9) of the user at the back leaning point (10) is counteracted by a restoring force in the lower region of the back part as a result of the articulated connection between the seat part and the back part (7).
