Title: Amniotic membrane graft or wrap to prevent adhesions or bleeding of internal organs
Inventor: YOUNG RONALD L
IPC: A61L27/00
Filed: 1995-02-21
Abstract: Disclosed is a specially treated sheet of amnion, such as an amniotic membrane which prevents adhesions following injury, such as surgical injury and prevents bleeding of internal organs caused by injury.  The amniotic sheet has its cellular monolayer removed exposing basement membrane, collagen types I, II, III, laminin, fibronectins, and other glycoprotein components which promote wound healing and remove antigenic sites in the cellular layer which may elicit an immune response.  The amniotic material is sterilized and may be cross-linked.  It is applied as a single layer to an injured surface subject to adhesions or wrapped on internal organs subject to bleeding, and can be sutured or applied by a liquid anti-adhesive adjuvant.  The graft can be applied to a wet as well as a dry surface.

Title: Four-way levelling mechanism for off-road vehicle
Inventor: WOODS RANDY JOHN
IPC: E02F9/12
Filed: 1993-10-15
Abstract: A four way tilt mechanism (15) for maintaining the super-structure (14) of an off road vehicle generally horizontal while the vehicle is working on uneven terrain is disclosed. The tilt mechanism is very robust and provides independent adjustment of the angle of tilt relative to each of two pivot axes (16, 17). The tilt mechanism (15) incorporates a spherical bearing (37) mounted on a shaft (38) perpen-dicular to the longitudinal pivot axis (16) of the tilt mechanism to eliminate end-play in the joint which forms the longitudinal pivot axis. The longitudinal and transverse pivot axes (16, 17) preferably lie in the same plane so that many of the the forces which are trans-ferred from the superstructure (14) of the vehicle through the tilt mechansim (15) to the chassis (13) of the vehicle cannot cause a torque on the components of the tilt mechanism.

Patent CA-2157584-A1 (CA)
Inventor: MULHAUSER PAUL
IPC: A61M11/00
Filed: 1994-02-28
Abstract: A woven or non-woven screen mesh disc impregnated at spaced locations along its circumference with a dose of powdered medicament.  The disc is selectively indexed so as to present the impregnated doses of medicament seriatim between a pair of holes in an upper and lower pressure plate in an inhalator. Air is forced through the holes in the pressure plates and the encapsulated screen mesh to entrain a dose of the powdered medicament, which is then inhaled through a mouth piece, by the patient-user. Because the powdered medicament is impregnated into the screen mesh, the air impinging upon the mesh and the powdered medicament will cause the medicament to break up as it is pressed up against and passed through the mesh infrastructure to aerosol of atomize the same so that the medicament is presented in appropriate particle sizes for maximum benefit when inhaled.

Filed: 1995-10-17
Abstract: Apparatus is disclosed to control a Yankee hood profile along the cylinder wrap so as to provide a structurally stable hood having controlled impingement distances at operating temperatures.  Radial support of the hot hood internals are located at or near the extremities of the hood wrap and the internal profile along the cylinder wrap is on an adjusted cold shape so that the profile is even when operating temperatures are reached.  Thus, the hood is "deformed" (not pre-strained) when cold but, when the operating temperature is reached, it assumes the desired configuration.

IPC: F41G7/30
Filed: 1995-10-20
Abstract: An error detector apparatus (42) producing a signal used in the computation of a missile guidance signal in an aircraft-based missile guidance and tracking system.  The error detector apparatus (42)  incorporates means (146), (148),  (150),  (152),  and  (154)  for producing a  first envelope  signal  from a  tracking signal  emitted by  a missile.

A microcontroller  (168) calculates an error correction signal from the digital signals.  A digital to analog converter (160) converts the digital  error  correction  signal  to  an  analog  error correction signal and outputs the analog error correction signal  to the system for use in computing a missile guidance signal.

Title: Adaptive tonal control system with constrained output and adaptation
Inventor: POPOVICH STEVEN R
IPC: G10K11/178
Filed: 1996-01-03
Abstract: An adaptive control system and method for actively canceling tones in an active acoustic attenuation system has an adaptive parameter bank. Adaptation of the adaptive parameter bank can be constrained with respect to the null space of a C model of an auxiliary path (e.g. speaker-error). Alternatively, output from the adaptive parameter bank can be constrained with respect to the effective null space of the C model.  The preferred system uses singular value decomposition, normalization, and demodulation to implement the methods of constraining output and adaptation.  The invention can eliminate stability and tracking problems associated with over-parameterization.

Abstract: A cargo container is fitted to the chassis of a truck tractor so as to be shiftable on rollers between first and second positions. The first position is adjacent the rear of the tractor cab, and the second position is adjacent a rear end of the tractor chassis. The bottom of the container is built with a centred longitudinal channel that allows the container to pass over a fifth wheel of the tractor when being shifted to the second position. The rear side of the container has one or more doors that can be opened when the container has been shifted to the second position and the tractor has been backed into a loading dock. This allows a forklift to be driven directly into the container from the loading dock, facilitating loading and unloading of cargo.

Title: Antisense oligonucleotides to suppress eicosanoid formation
Inventor: KNISS DOUGLAS A
IPC: A61P13/02
Filed: 1994-12-16
Abstract: The present invention provides new antisense oligonucleotides for the treatment of premature labor, premature rupture of the fetal membranes, premature cervical dilation and effacement, preeclampsia, endometriosis, rheumatoid arthritis, ARDs, and glomerulitis. The drugs are antisense oligonucleotides which attenuate the expression of either the mRNA encoding the cyclooxygenase protein or the mRNA encoding the thromboxane A2 synthase protein. Once the mRNA encoding for cyclooxygenase is inhibited, the production of the cyclooxygenase is inhibited thereby inhibiting the production of the cyclooxygenase products such as prostaglandins and thromboxane. Thus, the antisense oligonucleotides provide novel therapy for the treatment of diseases involving cyclooxygenase products, prostaglandins and thromboxane metabolisms. Such diseases include immunological reproductive, cardiovascular, dermatologic, central nervous system disorders in which the release of cyclooxygenase products effects the genesis and progression of the disease. A second object of the invention is to provide new reagents for the research and study of the diseases involving cyclooxygenase products.

Title: Double-locking mechanism for handcuffs
Inventor: ECKER ROBERT J
IPC: E05B75/00
Filed: 1996-06-21
Abstract: An improved double-locking mechanism for handcuffs is disclosed. In the preferred embodiments, a standard pawl and multi-piece slide-bolt assembly have been modified to prevent premature sliding of the bolt into its "double-locking" position, and to prevent dislodging of the bolt back into its "non-locking" position. The unique slide bolt, or the nearby lock casing, is angularly offset to create a fulcrum. The bolt also has an underlying tab that is designed to rest in either of two side-by-side locator notches atop a cuffs pawl. One notch firmly locates the bolt in a double-locking position, while the otha notch normally keeps it in a non-locking position. To shift the bolt into its double-locking position, an authorized user presses any suitable actuator (e.g., the tiny end of a handcuff key or a ball-point pen end) against an exposed inclined end of the bolt. This pivots the bolt about the fulcrum and against the casing, so that it lifts the tab out of the non-locking locator notch. Continued pressure by the actuator forces the bolt to slide over a ledge that separates the notches. Once the tab rides past the ledge, it re-pivots into the double-locking position. A spring action holds the tab (and bolt) in place until a user forcefully retracts the bolt when unlocking the cuffs.
