Abstract: Disclosed is a capnometry apparatus for receiving respiratory gas from a respiratory cannula positioned on a patient. An integrated host controller alerts a user if the capnometry apparatus is connected or not connected to the respiratory cannula based in part on a signal output from a capnometer located in the capnometry apparatus. The host controller also includes the functionality to shut off the capnometer pump with or without a time delay when the capnometer signal output indicates the capnometer pump is not connected to the cannula. An ambient-air pressure sensor located in the capnometry apparatus alerts the host controller if the capnometry apparatus has been moved to a new location with a substantially different altitude than the first location, in which case the host controller will issue an alert to a user prompting a calibration of the capnometry apparatus.

Abstract: Rolls of paper are converted by unwinding, cutting and stacking into a relatively high stack of paper sheets of a predetermined uniform size. At least one of the vertical corners of the stack is removed by running an electrically driven manual planer down the corner so as to leave each sheet with one or more corners having a notch for use in orienting the sheet such as in feeding it into a copy machine. The planer is equipped with guide means so that the corner notches all have the same predetermined size and shape. The planer is preferably equipped with a vacuum hose which removes the debris as it is formed and conveys it to a vacuumized collection chamber. Preferably, the stacks of paper sheets are accumulated onto the deck of a pallet having on the underside a support integrally formed from a sheet of material so as to have parallel channel formations adjacent to and inset from opposite sides of the deck. It is also desired to provide a center-post or pedestal.

Abstract: A hermetically sealed speaker enclosure assembled from pieces that can be shipped economically in compact knocked-down condition. The mating surfaces at the edges and margins of the assembled pieces are hermetically sealed by gaskets clamped therebetween. Some of the gaskets can be in the form of bands of compressible elastic material stretched around the peripheral edges of certain pieces or panels and seated in connecting grooves in the peripheral edges. Other of the gaskets are in the form of individual lengths of compressible material seated in certain of the borders or marginal edges. Appropriate fasteners are used to secure the pieces together in hermetically sealed relationship. Assembly of the speaker enclosure can be economically made at the place of installation of the speaker components.

Abstract: Apparatus for and method of making templates and the like wherein each stack of blank sheets is supported in raised position on a support platform and the space between the stack and the platform serves as a channel through which air is caused to flow in such volume and velocity as to remove the debris formed when template or similar openings are cut in the blank sheets by one or more cutting tools. Either the support platform or the cutting tool carrier or both may be controllably shiftable on the x and y axes, and either the support platform or cutting tool carrier or both may be vertically reciprocable on the z axis.

Abstract: Two sets of positive-locking tilt adjustment mechanisms are mounted between a drafting board and a supporting frame therefore. Both sets of locking mechanisms include identical left and right halves having crown gear portions positioned thereon for aligned meshing engagement with each other. Further, the opposing halves of the opposing sets of mechanisms are also aligned. Each half is manually mountable by hand to either the board or frame and a bolt and hand tightenable nut maintain the sets of mechanisms, the board, and the frame in adjustable alignment. The board and frame are made such that loosening a nut on each mechanism automatically separates the halves of each set thereof for providing interference free tilting adjustment of the drafting board on the frame.

Abstract: A cord clamp of integrally molded plastic construction particularly useful for adjustably securing a straightedge mounting cord to a drafting board. The clamp includes two mating, but not identical halves integrally hinged together like the halves of a clam shell. One of the halves of the clamp is adapted to be mounted on a drafting board or other support and may be considered as the mounting half. The other half is the one that swings open and closed and may be considered as the closing half. The mating surfaces of the two halves are interrupted by offset recesses which cooperate to define a labyrinth passageway capable of retaining a cord therein and clamping it between the two halves. A user may readily remove the cord from the clamp or adjust its position therein by manually opening the clamp without using tools and thus exposing the cord.
