Patent CA-2055826-A1 (CA)
Title: Improved helmet
Inventor: FEULING JAMES J
IPC: A42B3/04
Filed: 1991-11-19
Abstract: The disclosure is directed to an improved aerodynamic helmet. The helmet has a continuous aerodynamic curvilinear front, side and top surfaces whereby the fluid flowing over and around the sides of the helmet flows in a substantially continuous flow direction from the forward curved area aft of a straight area at the greatest width or largest transverse dimensions of the helmet after leaving the surface influence thereof. The continuous transverse surface around the outer periphery of the helmet at or slightly aft of the greatest width area is provided with a fluid flow termination surface or trailing edge causing the normal direction of the fluid flow around the helmet to break loose from the surface of the helmet and continue in substantially the same direction after passing the termination or trailing edge thereby preventing turbulence to the flow rather than allowing the fluid flow to follow the surface and flow around a portion of the smaller dimension back surface of the helmet before separating therefrom which creates turbulence behind the helmet and unwanted lift thereto. The improved helmet lowers wind drag compared to conventional helmet by about 40%.

Abstract: The new polypeptides have a defined of 446 amino acids or comprise fragments of it; provided the fragments; (i) contain at least those sites necessary for, when the fragment is exposed at the surface of a cell, binding to its (ant)agonists, specifically and in a measurable way (e.g. by means of a radioative ligand); (ii) can be recognised by Abs which recognise the full sequence but not dopaminergic D1 or D2 receptors; or (iii) can generate Abs recognising the full sequence but not dopaminergic receptor D1 or D2. The polypeptides include variants having licalised mutations provided they have not lost their dopaminergic receptor properties. Preferrred polypeptides show agonist affinity, by competition with the ligand iodosulphide-1 125, in the order quinpirole greater than apomorphine = dopamine and antagonist activity in the order raclopiriae greater than UH232 = haloperidol.

Title: Method for aligning an articulated beam delivery device, such as a robot
Inventor: AKEEL HADI A
IPC: B23P21/00
Filed: 1990-07-09
Abstract: A method is provided for aligning an articulated beam delivery device, such as a robot, by utilizing an electronic, high resolution television camera (66) as a transducer for measuring small beam deviations at relatively short distances. A display monitor (82) coupled to the camera is located in view of an operator of the robot to provide direct visual feedback for use during the aligning method. The aligning method includes the step of transmitting a collimated optical beam so that the beam travels along a first beam path and is deflected by an adjustable mirror (20) supported on an arm assembly (48) having first and second axes of the robot for rotation therewith about the first axis and thence along a second beam path. The beam is also deflected by at least one other mirror (22) supported within a wrist mechanism (60) of the robot to travel along a third beam path to a beam exit end of the robot.
Patent CA-2066684-A1 (CA)
Title: Therapeutic ribozyme compositions and expression vectors
Inventor: GOLDBERG ALLAN R
IPC: A61K47/48
Filed: 1990-09-25
Abstract: Hepatitis delta is used as a vector for inhibition of viral infection and to express proteins in vivo in a cell-specific manner. The scope of delta's use as a vector is broadened in the present invention in several important ways. For example, a delta RNA  genome capable of self-replication is enlarged to carry additional information, either coding for messenger RNA for a protein, or for a targeted ribozyme, which can be delivered to liver cells using delta's normally infectious properties, or to other cell types using chimeric delta viral agents carrying altered surface proteins. In another embodiment, the delta vector is made self-limiting, so that its role in delivering targeted information is separated from its viral property of unlimited infectious replication.  Targeting is achieved through the use of sequences flanking the delta sequences that have affinity for sites on RNA to be cleaved.

Title: Flow immunosensor method and apparatus
Inventor: LIGLER FRANCES S
IPC: G01N33/536
Filed: 1991-02-21
Abstract: A method of detecting a target moiety comprising the steps of (a) providing an antibody (37) specific to the target, (b) satu-rating the antibody's (37's) binding sites with a labelled form of the target (39), (c) flowing a liquid containing the target past the antibody (37), (d) allowing the target to displace the labelled antigen (39), and (e) detecting the displaced, labelled antigen (39).   The invention is accomplished by a flow immunosensor: a flowing liquid moves a sample through the immunosensor; a receiving means (13) introduces the sample to the liquid; a flow control means (21, 23) controls the liquid's movement through the immu-nosensor; and exchanger (35) brings the sample into contact with labelled antigens of the target so that any target present dis-places the labelled antigen (39); a detection apparatus (41, 41a) detects any labelled antigen (39) that is released; and a disposal means (45) disposes of or collects the waste coming from the detection apparatus (41, 41a).
Patent CA-2079584-A1 (CA)
Inventor: VARSHAVSKY ALEXANDER J
IPC: C12N15/11
Filed: 1991-05-14
Abstract: This invention pertains to the metabolic destabilization a protein or peptide of interest in vivo. The protein or peptide of interest contains a second determinant of the N-end rule-based degradation signal. The methods of the invention comprise contacting the protein or peptide of interest with a targeting protein or peptide which interacts specifically with the protein or peptide of interest. The targeting peptide or protein contains a destabilizing amino-terminal amino acid according to the N-end rule of protein degradation, but lacks a second determinant of the N-end rule-based degradation signal. A requirement of the methods is that it is necessary to identify a peptide or protein which interacts specifically with the protein or peptide of interest. Because nearly all proteins specifically interact with other proteins, this is a broadly applicable method for metabolically destabilizing a protein or peptide of interest in vivo.

Patent CA-2080498-A1 (CA)
Inventor: NILSSON JAN G I
IPC: F24F3/167
Filed: 1992-10-14
Abstract: The invention relates to a method of establishing and maintaining in sealed tents or the like mobile units, an environment which is independent of the surroundings with regard to temperature and contamination. The inven-tion is characterized by taking air from the surround-ings, extracting contaminated particles and gas from the air by filtration, and causing the air to pass into the mobile unit so as to establish a predetermined air pressure which is higher than the air pressure of the surroundings. The filtered air is mixed with air recy-cled from within the mobile unit when the aforesaid predetermined air pressure has been reached and mixing of the filtered air with recycled air is continued for as long as the internal air pressure is equal to or greater than the predetermined air pressure. The air mixture is heated or cooled to a predetermined tempera-ture and is then distributed essentially uniformly in the mobile unit and filtered, in conjunction therewith, so as to extract any remaining particles and gas.            The invention also relates to an arrangement for carry-ing out the method.

Abstract: In construction of a tool chuck in which manual rotation of an outer operation sleeve causes concurrent rotation of an inner screw ring to move clamping jaws in a chuck body following the principle of screw feeding, a solid lubrication coating layer is interposed between the screw ring and the chuck body so as to minimize friction between the two elements during their relative rotation for clamping a tool via the jaws, thereby effectively utilizing input torque from the operation sleeve for clamping operation.  The solid lubrication coating layer may be applied either to a washer or directly to the screw ring.
