Abstract: ABSTRACT OF THE DISCLOSURE         A flexible polyurethane foam composition characterized by high tensile or tear strength is prepared by reacting an MDI prepolymer, prepared by reacting a MDI having a low functionality with an ethylene oxide-capped polypropylene glycol polyol, with a small amount of a tetraethylene glycol as a cross-linking agent and an ethylene oxide-capped polypropylene glycol polyol, the reaction carried out in the presence of a blowing amount of a blowing agent, such as water or a halocarbon, and a catalytic amount of a polyurethane catalyst, such as a combination of an amine and tetravalent tin catalyst.  The addition of a small amount of a chlorinated phosphate flame-retardant agent mixed with the reaction provides for a polyurethane foam composition of good fire retardancy and which when exposed to open flame does not melt, but chars.          Further, the addition of a trimerization catalyst provides a foam composition with reduced shrinkage.

Abstract: ABSTRACT        A vehicle transmission that has a main multi-speed gear change mechanism is provided with a sub speed gear change mechanism particularly useful for four wheel drive vehicles.  The main gear change mechanism has parallel input and output shafts with the various gears and the sub speed gear change mechanism has an intermediate shaft and counter shaft parallel to the input and output shafts.  An input gear on the intermediate shaft continually meshes with a gear on the input shaft and an output gear continually meshes with a gear on the output shaft.  A gear reduction train and synchronizing mechanism selectively connects the input and output gears to establish that sub speed gear.  The intermediate and counter shafts do not extend beyond the input and output shafts therefore minimizing the length of the transmission.  The gear selecting mechanism allows selection of the sub speed only when the vehicle is in four wheel drive.

Abstract: ABSTRACT     METHOD AND APPARATUS FOR IN VITRO CALIBRATION OF OXYGEN     SATURATION MONITOR           A calibration reference apparatus comprising an elongated peripheral tubular wall open at one end and an end wall closing the other end of the tubular wall.  The tubular wall and the end wall are integrally molded.  The end wall defines a curved cavity opening toward the open end of the tubular wall.  The calibration reference apparatus is adapted to receive a light guide through the tubular wall and in the cavity.  A stop limits the extent to which the light guide can be advanced into the cavity whereby an end face of the light guide is spaced from a region of the surface to define a gap.  The end wall and the gap are adapted to return a known ratio of the light directed into the gap from the end face of the light guide.

Abstract: ABSTRACT         This invention relates to thermal mass transfer printing, and, in particular to a novel receptor sheet for such printing.          Pigmented wax from a donor sheet normally used in thermal mass transfer printing does not reliably adhere to bare, untreated polyethylene terephthalate film because lack of compliance of the surfaces of the donor sheet and receptor sheet makes contact between pigmented wax of the donor sheet and image receptive surface of the receptor sheet difficult.          The receptor sheet of this invention is suitable for use in thermal mass transfer printing and comprises a polymeric backing bearing on at least one major surface thereof a wax-compatible, image receptive layer having a softening temperature in the range of about 30°C to about 90°C, the surface of said image receptive layer having a higher critical surface tension than the donor material of the donor sheet from which pigmented wax is transferred to the receptor sheet to form images thereon.  A preferred receptor sheet comprises a backing made of polyethylene terephthalate and an image receptive layer formed from a blend of a wax and a copolymer of ethylene and vinyl acetate.

Abstract: A programmable low voltage compressor circuit suitable for use with hearing aids is described. The compressor has a continuously variable compression ratio wherein the gain of the compressor may be programmably controlled over a wide range and the compressor may be powered from a power source as low as 1.1 volt. The compressor employs a variolosser wherein the gain is controlled by the ratio of the currents flowing out of first and second control terminals. A control circuit coupled to the variolosser controls the magnitude of the currents flowing out of the two control terminals. The control circuit includes a peak detector which generates a signal related to the peak positive envelope of the signal input to the compressor. A voltage to current converter is coupled to the peak detector for increasing the magnitude of the current flowing out of one of the control terminals of the variolosser as the voltage output of the peak detector increases. Furthermore, the gain and compression ratio of the compressor over a wide range is programmably controllable.
