Patent CA-2252008-A1 (CA)
Inventor: MCDUFF PIERRE
IPC: F16B13/00
Filed: 1998-10-28
Abstract: A combination wall anchor and support fastener comprises a wall anchor adapted to be securely installed in a support structure such as a wall or a ceiling, and a support fastener having an elongated member or stem and a proximal support system. The wall anchor defines an inner bore delimited by an inner wall. The elongated member is insertable in the bore. A locking mechanism is provided for locking the elongated member to the inner wall upon sufficient translational insertion of the elongated member in the bore. Therefore, with the wall anchor secured to the support structure, the support fastener can be inserted in the wall anchor and locked thereto with the support system being usable for suspending, mounting, attaching, etc., an item to the support structure. The locking mechanism may comprise a recess defined in the inner wall and at least one tooth protruding sideways from the stem.      Typically, a number of axially spaced and aligned teeth are provided on the outside of the stem, with each tooth being adapted for engagement in the recess such that various locked relative positions can be obtained between the wall anchor and the support fastener. The locking mechanism can be disengaged by rotating the support fastener with respect to the wall anchor.

Title: Extension apparatus and method
Inventor: LUCAS GREGORY T
IPC: B65H29/12
Filed: 1997-07-29
Abstract: The present invention relates to an apparatus and method for providing a conveying path for advancing sheet articles between sheet processing apparatuses. Conventional apparatuses for providing conveying paths of varying lengths include a translatable extension table with a sliding belt/pulley arrangement. Such arrangements prevented complete abutment of the table with the downstream sheet processing apparatus and required manual adjustment of belt tension. The present invention overcomes these disadvantages through a novel extension apparatus. The extension apparatus (10) includes a base bracket (40) with a pair of rotatably movable spring-loaded bracket arms (44A, 44B) attached to a shaft (42) extending therethrough. A pair of bracket arms rollers (46A, 46B, 48A, 48B) are attached to each of the bracket arms. An extension plate (30) is positioned above and slidably movable on the base bracket, and a pair of rotatable extension rollers (20A, 20B) are rotatably attached to a shaft (22) extending through the extension plate such that slidable movement of the extension plate simultaneously and identically moves the extension rollers. A pair of rear rollers (R2, R4) are utilized and are operatively aligned with an extension roller and a pair of bracket arm rollers. A pair of belts extend at least partially around and operatively engage one of the rear rollers, one of the extension rollers, and a pair of the bracket arm rollers of one of the bracket arms. The belts have an upper reach section and a lower reach section between the rear rollers and the extension rollers, and the upper reach section of the belts from a conveying path for advancement of the sheet articles while the bracket arm rollers engage each belt in the lower reach section.

IPC: A61B5/087
Filed: 1998-03-13
Abstract: An indirect calorimeter for measuring the subject's oxygen consumption per unit of time employs a mouthpiece (12) through which the subject breathes for a period of time. Conduits connect the mouthpiece to a flow meter (14) and a capnometer (26) so that the subject's inhalations, and exhalations pass through the flow meter, and the exhalations also pass through the capnometer. Electrical signals from the flow meter and capnometer are provided to a computer (22) which calculates the CO2 exhaled by the subject during the test by integrating the instantaneous CO2 content of an exhalation as measured by the capnometer over the volume as measured by the flow meter, substracts that quantity from the exhaled volume, and substrats their difference from the inhaled volume. In alternative embodiments the system can also measure the subject's cardiac output and delivered oxygen.
