Abstract: Accordingly, the present invention provides a collapsible carrier for transporting loads comprising a support member having two legs and an adjoining cross arm. A fold out platform device is pivotably connected to the support member for holding the loads. A telescoping handle apparatus is affixed to the support member for moving the carrier. A cylindrical wheel device having a wide slightly tapered rolling surface comprising a pair of cylindrical symmetrical surfaces upwardly tapering from a common contact point or edge is adjoined to the handle apparatus for minimizing the surface area of the wheel device contacting a travel surface along which the load is transported while increasing the stability of the carrier to facilitate the carrier rolling straight while decreasing the tendency of the carrier to laterally trip over under heavy load conditions as it is pulled along the travel surface.

Abstract: Fat in a fat-containing sample, in particular a milk sample, is determined quantitatively by infrared absorption technique, using as sample waveband a band characteristic to carbon-hydrogen bonds, instead of the conventional triglyceride carbonyl band. This avoids the dependency of the measured result on the fat composition of the sample. Influences from other components in the sample are compensated for. A preferred method uses double wavelength determination, with sample wavelength in the interval from 3.475 to 3.51 .mu.m and reference wavelength in the range between 3.51 and 3.60 .mu.m.

Abstract: A new class of fluorosulphonyl oxafluoroalkanes and their derivatives is disclosed as well as a process for preparing said products. Furthermore, a new class of fluorosulphonyl olefins, copolymers thereof and a process for preparing same is also disclosed.

Abstract: New and improved single limb breathing circuit assembly for use in a circle absorbed anesthetic system is disposed within and surrounded by the expiratory limb to provide for heating of the inhaled gases by the exhaled gases. Valve means insure that substantially all exhalation occurs in the expiratory limb and that substantially all inhalation occurs in the inspiratory breathing limb to prevent re-breathing of exhaled carbon dioxide. The absorber comprises inlet and internal outlet conduits which combine to assure the flow of gases from the absorber at high humidity levels. Valve means are also provided to proportion the fresh gas inflow to the absorber between the inlet and outlet conduits to enable control of the humidity of the gases flowing from the absorber within a predetermined range. The various portions of the system are arranged so as to minimize both heat and moisture loss in the inhaled gases passing through the absorber for conveyance to the patient.
