Abstract: In a respiratory air flow measuring monitor, a subassembly for analyzing certain respiratory gases through infrared spectroscopy includes an infrared emitter and an infrared detector, the amount of energy detected by the detector corresponding to the concentration of the gas selected for analysis. The subassembly includes a gas sample chamber that utilizes an elliptical reflecting surface for the infrared light source. The light source and detector are both oriented longitudinally along the axis of the ellipse and the light source and detector are each located at the two focal points of the ellipse in order to optimize the light absorption reading. The gas content analyzer subassembly additionally incorporates various compensatory features, allowing for automatic temperature and pressure compensation.

Abstract: A corner guard assembly for protecting the corner of a building wall particularly in institutional type facilities from damage due to impacts with wheeled vehicles includes an elongated vinyl corner guard member angled to fit over the corner formed by the intersection of two wall surfaces, the corner member being comprised of two different colors of vinyl plastic material that have been co-extruded to form a single, integrated product. The multi-colored corner guard provides an aesthetically improved corner guard that may be used in a wide range of interior designs. Additionally, the improved corner guard disclosed herein may be used a part of a system of color-coding the hallways of a large hospital or other institutional facility. The corner guard of the present invention may be constructed as either a tape-on corner guard that is mounted by an adhesive directly to the wall surfaces, or constructed as an assembly comprised of a base plate and cover guard.

Abstract: An apparatus and method of winding a continuously moving web, and for splicing and transferring the web from a first core to a second core with no-fold-back or wrinkling of the web material during the splice. The web is fed through a first nip point and thereby applied to a lay-on roll, the lay-on roll further applying the web material onto first and second cores alternatively. An electrostatic charging bar positioned downstream from the nip point emits an electrostatic charge onto the web to temporarily adhere the web to the lay-on roll. A rotatable cutting knife cooperatively engageable with the lay-on roll cuts the web at a point downstream from the electrostatic charging bar but upstream from the first and second cores to produce a tail and new leading edge. The tail continues to be wound about the first roll, and the new leading edge is affixed to the second roll and the web is thereafter wound about the second core.

Abstract: A bicycle saddle including a contoured upper seating surface that primarily supports the rider's ischeal tuberosities and further including a depressed, extremely soft central anterior portion to reduce pressure placed on the perineum is disclosed. The saddle is essentially constructed from a shell, foam padding, a self-contained gelatin pack, a leather cover, and a suspension rail for mounting the saddle onto a bicycle. The seating surface of the saddle includes laterally spaced apart right and left cup-shaped posterior support surfaces for supporting primarily the right and left ischeal tuberosities in the buttocks of the bicycle rider. The right and left posterior support surfaces are formed by a pair of essentially concave depressions in the posterior portion of the shell of the saddle, and corresponding cup-shaped depressions in the foam padding covering the shell.

Abstract: A controller for controlling the flow rate of compressed air to a spray paint gun as well as to a comparable tool which is optimally operative dependant upon receiving a specified flow rate of air includes a flow control valve which regulates the air flow rate therethrough based on a pressure differential signal received from an air flow meter. The pressure differential signal transmitted to the air flow controller is balanced against an opposing spring biased needle in the flow controller.

Abstract: A bicycle rear suspension system providing rearward relative motion of the rear axle includes a chain stay, seat stay, chain stay link, seat stay link and shock absorber, with those components being assembled to a main front frame. The frame includes a head tube for supporting a front steering fork, a seat tube for supporting a seat, and a bottom bracket for supporting a pedal crank and chain drive mechanism, the seat tube and bottom bracket being supported so that there is a vertical space between them. The components of the rear suspension system are assembled to the frame within the space between the seat tube and bottom bracket. The chain stay link is pivotally attached to the frame so that, upon upward movement of the chain stay, the chain stay link pivots to cause the chain stay and thus the rear axle supported thereon to move slightly rearwardly relative to the frame.
