Title: Servo-control for a transmission
Inventor: KLATT ALFRED
IPC: F16H63/20
Filed: 1982-02-12
Granted: 1986-01-16
Abstract: A remotely controlled automotive transmission shifting mechanism for effecting engagement of the respective gears with a force that varies in accordance with the gear selected. Pneumatic pressure from a compressed air storage tank is connected via a choke to a pneumatic actuating cylinder that effects gear engagement. A signal corresponding to the instantaneous pressure effective at the actuating cylinder is compared in an evaluating circuit with a reference value assigned to the gear selected. When the compared signals match, a solenoid valve is actuated to cut off further pressurization of the actuating cylinder and thereby modulate the gear actuating force in accordance with the gear selected. Following gear engagement, the gear actuating pressure is released.

Granted: 1991-06-20
Abstract: Present invention presents a novel mechanism for reducing the amount of storage space necessary to perform error checking and correcting in a storage unit of a data processing machine by utilizing the information present in the parity checking portion of the storage unit. The novel mechanism is based on generating an error checking and correcting code which includes a first portion identifiable by parity bits normally stored with data words in a data storage device and a second portion. The second portion contains fewer bits than required in the prior art for an equivalent level of error checking and correcting and only the second portion is stored. When data is moved out of the storage device, the first portion is identified from the parity bits.

Abstract: A transmitter provides an output representative of a parameter. A generating circuit in the transmitter senses the parameter and provides charge packets having adjustable magnitudes to a measurement circuit. The measurement circuit measures the quantity of charge and provides a measurement signal representing the charge to a feedback circuit. The feedback circuit is controlled by the measurement signal and provides timed feedback signals to the generating means. The feedback signals control the generation and magnitude of the charge packets such that the charge coupled to the measurement circuit is finely balanced in a short measurement interval. The feedback means counts the number of charge packets provided during a measurement interval such that the numbers counted are representative of the sensed parameter.

Abstract: S-(-)-atenolol (4-(2-hydroxy-3-isopropylaminopropoxy)phenyl acetamide) is obtained by a process including the step of stereo-specific epoxidation by an ester of 4-allyloxyphenylacetic acid using a micro-organism capable of stereo-selective epoxidation, e.g. Pseudomonas oleovorans, to produce the corresponding ester of 4-(2,3-epoxypropoxy)phenylacetic acid which is predominantly in S configuration. Pseudomonas oleovorans ATCC 29347 produces at least about 90% of the epoxypropoxy compound in S configuration. The resulting epoxypropoxy compound can be converted into atenolol, maintaining the high proportion of S configuration, by reacting the epoxypropoxy compound with isopropylamine and converting the ester group to an amide group by reaction with ammonia.
