摘要： A remote, manual shift system cooperating with the clutch, throttle and gear shift stick of a manual transmission vehicle for use during engine testing includes a series of five sensors, one each for vehicle speed, throttle position, clutch position, X-axis gear shift position and Y-axis gear shift position. These five sensors are operable to record and compile actual drive test data reflecting the actual operation of the vehicle during the test drive. This data is recorded and the recording is then processed by an electronics circuit which in turn provides actuating signals of a DC voltage level to a series of servos which are arranged in mechanical combination with the clutch, throttle and gear shift stick of the vehicle under test. As these various servos are actuated with an appropriate input signal, they perform the shifting from one gear to the next gear along with proper depression of the clutch and acceleration by means of the throttle. The use of actual test data from an actual road test provides a more reliable and improved data package for the operation of the servos and results in a more desirable vehicle test, such as might be performed on a dynamometer test station.

摘要： Micro-suspension polymerization is a technique that it is widely used on a commercial basis for the polymerization of vinyl chloride monomer into polyvinyl chloride. This invention reveals a greatly improved redox initiator system for use in such polymerizations. The redox initiator systems of this invention are comprised of (a) a free radical generator, such as a peroxide, and (b) a reducing agent selected from the group consisting of ascorbic acid, isoascorbic acid, and certain derivatives of ascorbic acid. The initiator systems of this invention do not require the utilization of water-soluble metal salts. However, water-soluble metal salts can be utilized in such initiator systems in catalytic amounts wherein the ratio of the water-soluble metal salt to the free radical generator is less than 0.09.
