Abstract: A process for producing a sucrose fatty acid polyester comprises reacting sucrose with fatty acid lower alcohol ester(s) in a solvent in the presence of an alkaline catalyst, wherein said fatty acid lower alcohol ester(s) are employed in an amount at least 5 times by mol as much as said sucrose. The alkaline catalyst component is removed from the reaction product thus obtained and the obtained sucrose fatty acid polyester-containing solution is catalytically treated with activated clay. This process enables the production of a sucrose fatty acid polyester containing an extremely small amount of ash components and having an extremely low color value. The alkaline catalyst used in this process may be recovered and reused, which further makes the process of the present invention advantageous.

Abstract: A circuit for separating a PAL color television signal into a luminance signal and color difference signals. The PAL color television signal is sampled (2) in phase coinciding with color burst and at a sampling frequency four times as high as that of chrominance subcarrier. A part of the sampled signal is delayed for one frame by a frame memory (4), and difference between the sampled signal and the one-frame delayed signal is determined by a subtraction circuit (6). The one-frame difference signal is then divided into first and second inter-frame difference signals (b). From the first inter-frame difference signal (b₁), motion information is detected by a detector (8) for controlling a mixing ratio of a mixer circuit (9) serving for mixing the second inter-frame difference signal (b₂) and an interline difference signal (a). From the output of the mixer circuit, chrominance signal is demodulated (10) for every other pixel and interpolated (11) for the interposed pixels to obtain the color difference signals.

Abstract: For accurately determining the position of a positioner, two endless potentiometers (8, 11) are used, the sliders of which are driven at transmission ratios which differ from one another. The angular position of the positioner can be determined with high accuracy from the differential voltage (d) of the voltages (U1, U2) picked up from the sliders at the potentiometers (8, 11). By using endless potentiometers, the device for determining position is not subject to any mechanical limiting. …<IMAGE>…

Abstract: A safety closure device for a closeable container is provided which, at the user's option, can be operated in a child-resistant mode of operation or, by a simple one-time action by the user, can be placed in a non-child-resistant mode of operation. An outer cap (22) rotatably and slidingly engages an inner cap (26) that directly closes a container, with an intermediate element (24) biasing the outer and inner caps apart from each other but formed so as to take up a first position in which an axially applied force by the user temporarily non-rotatably couples the inner and outer caps for child-resistant operation, and an axially applied force on the intermediate element coupled with a partial turning of the outer cap relative thereto causes permanent non-rotatable engagement between the outer and inner caps through the intermediate element to make the safety closure non-child-­resistant.

Abstract: The armature (54) contains an elastomeric valve head (58) that is biased normally closed against the valve seat (16). When the solenoid assembly (20) is energized, the armature is retracted. The armature's momentum is initially absorbed by the elastomeric valve head making contact with the solenoid assembly at one end of the bore. Final absorption of the armature's momentum is shared by continuing contact of the valve head with the solenoid assembly and by an elastomeric limit stop (60) that is disposed between the armature and the stator (34). In this way the elastomeric limit stop is not required to absorb the full momentum of the retracting armature.

Abstract: A bus master interface command protocol for use with a computer system having an intelligent mass storage disk array subsystem, including a bus master and microprocessor controller. The command protocol permits the computer system to issue disk array commands to the controller at a logical level without having to issue disk specific commands. The disk array subsystem microprocessor controller reads the logical commands, translates the commands into smaller disk specific commands, and queues the disk specific commands for processing. Upon completion of the logical command, the bus master controller asserts control over the computer system bus and manages the transfer of data to or from the computer system memory. The management of the disk array subsystem and the transfer of data is effectively off-loaded from the system processor permitting more efficient use of the processor.
