Abstract: Optically active alcohols represented by the formula:
     wherein X indicates an alkyl group having a carbon number of 2-10, Y indicates an alkyl group having a carbon number of 1-3, CF 3  or CN, and X ≠ Y, have optical isomers, so that these alcohols do not sufficiently exhibit activity in many cases unless either R- or S-alcohol is purely contained. The production of the pure R- or S-alcohol was restricted to a few methods, so it is desired to develop a method for optically resolving of the secondary alcohols by an industrially advantageous method. 
     This invention comprises using a particular enzyme having the ability to conduct preferentially a transesterification reaction with a triglyceride and an (R, S)-alcohol represented by the above formula and the triglyceride to conduct the transesterification reaction under substantially anhydrous conditions and resolving the resulting ester to obtain an optically active alcohol which contains richly either R- or S-alcohol.

Abstract: An alphanumeric character is recognised by optically scanning that character, detecting the occurrence of predetermined geographical features in the scanned image, comparing the detected geographical features to a store of particular geographical features which identify respective alphanumeric characters, and identifying the scanned image as the alphanumeric character having those geographical features to which the detected geographical features favorably compare. The aforementioned geographical features comprise lagoons (formed as enclosed areas) and bays (formed as open areas). The types of bays and lagoons, as well as the relative positioning of such bays and lagoons with respectto each other, characterize the respective alphanumeric characters. By detecting the bays and lagoons and relative positions thereof in the scanned image, the identity of that image is ascertained.

Abstract: A method and system for high-speed, 3-D imaging of an object at a vision station including a flying spot laser scanner, a dynamically configurable spatial filter and a diffuser for spatial averaging, are used in conjunction with a variable transmission filter in an optical depth sensing system. The reflected laser signal received by the sensing system is first spatially filtered and averaged and then split into first and second beams which are imaged onto a pair of highly sensitive photodetectors which introduce capability for high-speed, 3-D sensing under low light level conditions. The first beam passes through a variable transmission filter which is used to encode position which, in turn, is proportional to the height of the object. The second or reference split beam is provided to compensate for changes in the reflectance of the object and the power of the laser scanner. A high-speed signal processing unit which incorporates special circuitry to greatly extend dynamic range computes the ratio of the transmitted signal to the sum of the reference signal and the transmitted signal to determine height information. The signal processing unit also contains noise rejection circuitry which is activated during "off" and "on" periods of laser diode TTL modulation and includes feedback control for pulse amplitude modulation of the laser diode source if necessary to increase dynamic range of the system.

Abstract: A film drive (83) in a camera is actuated to advance a filmstrip (F) from a cartridge (C) to position respective frames on the filmstrip for exposure. Normally the film drive is disabled to prevent advancement of the filmstrip when the camera is in a non-picture taking or storage condition, as for example when an integral lens cover (1) of the camera is closed. An exception is created, however, whereby the film drive may be actuated to initialize a fresh film load by advancing the filmstrip to position its first frame for exposure even though the lens cover is closed. This is possible when respective sensor devices (SW C , SW F ) in the camera determine that a cartridge is in the camera but the filmstrip has not been initialized. Exposure of the first frame on the filmstrip can not occur unless the lens cover is opened.

Abstract: A circuit for delivering a predetermined amount of energy (E) to a load without regulating the voltage across the load is described. An a.c. or rectified sine wave is controlled. There is no capacitive smoothing of the applied voltage. A time counter (38) is activated at the beginning of each half cycle of the sine wave. At a predetermined point in time, a switch (S) is closed and power (P) is delivered to the load. At another predetermined time in the same half cycle, the actual applied voltage is measured. The detected voltage value and corresponding time of measurement comprise a unique signature enabling identification of the specific sine function for that half cycle. The sine function signature permits calculation of either the amount of total energy delivered or the RMS voltage level as a function of progressing time, and thus, determination of the time period for which the line switch must remain closed in order to deliver the predetermined amount of total energy, or to maintain a predetermined RMS voltage. When the time counter (38) reaches the computed necessary time period, the switch (S) opens and power delivery is stopped.

Abstract: A control system for a turbomachine such as a steam turbine includes an integrated control and display system (32,34) with means for automatically reconfiguring itself for each phase of operation. In each phase, only those displays and controls (60,62,64,66) required during that phase are provided; all other controls and displays are omitted. In one embodiment, inputs from the turbomachine pass through a decision tree for uniquely determining the phase of operation. The output of the decision tree selects and display and control parameters from a screen library. The screen library controls and positions of indicia and indicators on the displays and controls. The indicated values are determined from measured parameters. In one embodiment, a touch screen is employed for executing controls. The X and Y values of touch-sensitive parts of the screen are interpreted in terms of the intended control functions for the particu­lar existing phase of operation.
