Patent CA-2052344-A1 (CA)
Inventor: LEAVITT JOHN N
IPC: B64D47/08
Filed: 1991-09-27
Abstract: Apparatus for mounting a camera on a vehicle, such as a helicopter, to dampen the transmission of undesired motion from the vehicle when moving to the camera.  The apparatus includes an elongated suspendable structure with a large inertia relative to the camera.  The structure has a boom, for supporting the camera, extending from one end of an attachment portion of the structure, and a counter-balance beyond an opposite end of the attachment portion.  The apparatus is rigidly securable to the vehicle and resiliently compliant damping is operable between the vehicle and the attachment portion of the suspendable structure to dampen the transmission of undesired motion from the vehicle to the camera.  The damping has a center of compliance substantially at the center of gravity of the suspendable structure.

Abstract: HOT SPOT DETECTION AND SUPPRESSION SYSTEM            Abstract of the Disclosure A hot spot detection system (78) at one location that is fixed with respect to the rotor (12), and a temperature suppression system (62) at another location that is fixed with respect to the rotor.  The suppression system is automatically energized by the hot spot detection system when a threshold temperature is detected.  Preferably, the suppression system includes one or more pipes (66) that span the radial dimension of the heating element compartments in the rotor.  The detection system can be in the conventional location, on the trailing edge (40) of the air inlet duct (32) of the air preheater.  The suppression piping (66) is preferably located in the hot end, or air discharge duct (34), of the air preheater.  Depending on the location of the suppression piping with respect to rotor rotation, a timing device (100) is preferably employed to start and stop the flow of suppression water into the rotor, just prior to and after the hot spot passes under the piping.

Title: Apparatus and method for a combination valve
IPC: A61M39/00
Filed: 1991-12-12
Abstract: A combination valve in a side port adapter prevents back flow through the side port and through a main channel has an adapter with a main channel along an axis thereof. The adapter has a side port that intersects with the main channel for flow therethrough.  A resilient member with a passage therethrough has therein a check  valve  located normal  to the  axis  and across  the passage.   The check valve opens with flow along the axis in a direction and closes to flow in an opposite direction.   The resilient member normally closes the intersection until the member deflects when fluid pressure within the side port exceeds its  resiliency.   The check  valve  is  a  web  across  the passage with  a  slit that  is normally closed.   The web shape is a duck bill.  The main channel has an inlet and an outlet positioned along the axis.   The outlet can be connected for fluid tight communication to a catheter or other  fluid  line.   The  inlet  is  in fluid communication with a fluid supply  to  provide  flow  through  the main channel to the outlet.  The resilient member and the main channel have  a  cylindrical  shape  of  a  circular  cross section.  The resilient member has an edge at a distal end thereof.  The adapter has an annular shoulder within the main channel  distal  along the axis and relative to the side port to locate the edge.  A method has the steps of providing an adapter with a main channel and a side port, placing a resilient member having a passage therethrough in the main channel to prevent flow from the main channel to the side port and providing a duck bill check valve in the passage to permit flow through the main channel in one direction and prevent flow in the opposite direction.  The valve and adapter are packed and sterilized.

Inventor: EVANS ROBERT W
IPC: E21B31/113
Filed: 1991-12-18
Abstract: A double acting hydraulic drilling jar 1 includes a mandrel 2 arranged in a housing 3 for sliding longitudinal movement. A hammer 69 is positioned on the mandrel 2 and interacts with anvil surfaces 64, 66 in the housing 3 to deliver both upward and downward jarring forces to a drill string. A hydraulic valve arrangement permits the storage of large amounts of static force before releasing the hammer 69 to strike the anvil surfaces with great force.      The hydraulic valve arrangement includes a tripping valve 95 positioned to be actuated by a first pair of engaging surfaces in response to downward movement of the mandrel 2 in the housing 3 and a second pair of engaging surfaces in response to upward movement of the mandrel 2 in the housing 3. Thus, independent control over the upward and downward jarring action is achieved.

Title: Feedthrough coaxial cable connector
Inventor: MCMILLS COREY
IPC: H01R24/38
Filed: 1990-06-08
Abstract: A feedthrough coaxial cable connector includes a tubular mandrel body dimensioned to be pressed between a foil-bonded dielectric core and other elements of an outer conductor of the prepared end of the cable. The body has cable engagement surface which defines a knife edge projection therearound for engaging an outer conductor of the cable by creating shear stresses therein without actually shearing the outer conductor. A tubular shank portion extends from the cable engagement surface portion to a radial wall portion, and a jack engagement portion is coaxial about the exposed central conductor. The jack engagement portion achieves a tight friction fit upon a jack and may be formed as an inside compression collet. A radial compression providing structure causes an inside surface region of the outer conductor to bear directly against and bend over the knife edge portion. Preferably, a slideable shell is slideably positionable generally away from a connector end facing the outer surface of the jack to enable the jack engagement portion of the connector to slide over the outer surface of the jack, and slideably positionable toward the connector end so as to radially compress the radially diverging jack engagement portion against the outer surface of the jack to secure the connector thereto. A kit of parts including an expandable installation tool enables proper assembly of the cable connector without special skills or tools.

IPC: G01N21/35
Filed: 1991-12-04
Abstract: ABSTRACT     In order to increase the reliability of detection of gaseous contamination in containers, gas (G) from the container is subjected to several different methods of analysis (54a to 54d), each of which emits differing output signal courses (I1 to I4) depending on the contaminants and their concentration.  A vector of the state vector type (P Gas) is formed with the output signals (I1 to I4) as a state variable and checked to see whether it defines a permissible or an unacceptable state of contamination (56).  On the basis of this examination the decision is taken whether a container is acceptably or unacceptably contamined.
