Abstract: Oligoesters having hydroxyl groups and an OH number of from 200 to 600 mg KOH/g are made by reacting a cyclic dicarboxylic acid anhydride in which no halogen is present with a polyfunctional alcohol or dialkanolamine in a molar ratio of from 1:0.5 to 1:1.5 at a temperature of from 50 DEG  to 150 DEG  C. to form the corresponding dicarboxylic acid semiester and/or semiamide. This semiester and/or semiamide is then alkoxylated with ethylene oxide and/or propylene oxide in the presence of a catalyst at 80 DEG  to 150 DEG  C. The equivalent ratio of acid groups to alkylene oxide groups is from 1:0.8 to 1:1.7. The catalysts are reaction products of alkoxides with at least 3 C-atoms with ammonia, piperidine, piperazine and/or C2-C6 aliphatic, polyamines, preferably diamines in which all of the NH-functional groups have been alkoxylated. The resultant oligoester may then be reacted with a polyisocyanate optionally in the presence of known additives, such as blowing agents and catalysts.

Abstract: Combustible impurities in oxygen-containing offgases are burnt according to a method and by an apparatus of the type in which at least some of the heat of combustion is recovered by a regenerative heat exchange in two identical heat exchange zones (10,11) containing a solid heat exchange material and separated by a combustion chamber (15). The air or gas to be purified flows through both of the heat exchange zones and by means of valves (1,2,3,4) the direction of flow is changed periodically so that the two zones are alternately heated and cooled in periods of 0.1-60 minutes. The risk of discharge of unburnt combustible contaminants to the atmosphere is minimized by dividing the purified gas stream in the first 1-50% of each period into two part streams of which one is discharged directly from the combution chamber (15) to a recipient (22) whereas the other is passed through the heat exchange zone (10 or 11) being heated and from there recycled through a line (25 or 24) controlled by a valve (7 or 6) and combined with unpurified gas being passed to the heat exchange zone (11 or 10) being cooled.

Title: Battery separator with integral thermal fuse
Inventor: TASKIER HENRY T
IPC: H01M50/489
Filed: 1990-03-28
Granted: 1994-12-13
Abstract: A battery separator includes a porous substrate and a thermal fuse material adhered to at least one surface of said porous substrate.  The thermal fuse material is adhered to the substrate surface in a predetermined geometric array thereupon so as to establish open areas of the at least one substrate surface to thereby allow ionic migration therethrough.  The thermal fuse material forming the geometric array on the substrate surface may itself define open pores to further facilitate such ionic migration.  The thermal fuse material melts at or near a predetermined threshold temperature so that the substrate's permeability irreversibly becomes significantly decreased and thus interrupts the chemical reaction in an electrochemical battery.  In such a manner, batteries of improved safety may be provided using the separators of this invention.

Granted: 1998-04-07
Abstract: Disclosed is a suspending strap lodging device which allows a suspending strap to be extracted from a portable object, such as a bag, or withdrawn into it in accordance with whether the strap is needed or not.  The device comprises:  a withdrawing mechanism for allowing the strap to be extracted or withdrawn a desired length; a locking mechanism for controlling movements of the strap steplessly in both the lodging and the extracting directions; and a releasing mechanism for cancelling the locking effected by the locking mechanism.  The locking mechanism provided in the withdrawing mechanism prevents the weight of the portable object or the impact load caused when the object is lifted from being directly exerted on the strap, thereby enabling the strap to be securely locked in position and allowing it to enjoy a long service life.  Also disclosed is a strap equipped with a strap lodging device.  Since it is equipped with a lodging device of its own, this strap can easily replace the straps of existing portable objects.          Further, disclosed is a mounting structure for allowing a strap lodging device to be mounted on a portable object.          The structure, which can be applied, for example, to a video camera, adopts a single strap which serves as a shoulder strap, a grip strap, and a hand grip.

Title: Method and apparatus for high-speed bi-cmos differential amplifier with controlled output voltage swing
Inventor: REED JOHN A
IPC: G11C11/416

Granted: 1995-10-10
Abstract: The present invention provides apparatus and methods to achieve a high speed bi-CMOS differential amplifier with controlled output voltage swing for use in amplifying low level complementary logic signals.  The differential amplifier iscomprised of a load current controller and a sense amplifier. The load current controller compares a desired reference voltage to the voltage drop across a simulated load. The load current controller then produces therefrom a bias voltage corresponding to the current which results in a voltage drop equal to the reference voltage. The bias voltage, when applied to the sense amplifier, limits the output of the sense amplifier to a controlled voltage swing of magnitude equal to the reference voltage.
