Abstract: ABSTRACT        An optoacoustic cell is a device which measures the amount of light energy absorbed in a medium through the acoustic pressure resulting from the absorption.  The cell normally consists of a container with a pressure measuring device,  In particular the two functions may be combined if the container, a piezoceramic cylinder, is itself a pressure measuring device.  The medium under study is contained in the cell by an optical window of windows.  In the present example two windows seal the ends of the cylinder which contains a fluid to be identified.  Commonly, one of two types of light beam traverses the cylinder axis of the optoacoustlc cell: either (1) a periodically modulated light beam of continuous, constant intensity or (2) a short duration light pulse.  In this application we employ the second type.       The advancement in the art consists in the recognition that the signal produced by the pressure measuring device depends both on the type of piezoceramic cylinder used and the exact nature of the contained fluid.  The dependency is complicated and when the signal of the pressure measuring device is viewed against a time axis a pattern results, commonly called a fingerprint, which is specific to the particular fluid contained in the optoacoustlc cell.  The reason for this fingerprinting ability may be explained on the basis of the natural oscillation modes in the cylinder.       The utility of the invention lies in its providing a new means for identification of fluids.  Fluid mixtures could also be identified.

Abstract: 1022.021 S P E C I F I C A T I O N     Title:  CAPACITIVE BRAKING SWITCHING         SYSTEM FOR HOME APPLIANCES WITH INDUCTION MOTOR DRIVE     Inventor:  Daniel R. Benjamin Abstract Of The Disclosure An improved capacitive braking system is provided for fractional Horsepower induction motors in home appli-ances, for example in a food processor of the type having a working bowl mounted on a housing containing the induction motor, with a shaft in the bowl for removably supporting a rotary food processing tool to be driven by the induction motor.  The new braking system rapidly halts the coasting motion of the motor rotor and tool after the motor has been disconnected from the electric power line.  A first switch is provided to control the application of electrical energy to the induction motor for sustained operation, and a second "pulse" switch is provided to control the application of electrical energy to the induction motor for brief surges of momentary operation.  The braking system includes a second capacitor which is external to the induction motor and distinct from the starting capacitor normally associated with an induction motor.          In the preferred embodiment, this second capacitor becomes connected in circuit with the windings of the induction motor to provide an enhanced braking effect upon discon-nection of the induction motor from the electric power, said second capacitor having a capacitance larger than that of the starting capacitor for producing a resonant magnetic field braking action on the coasting rotor.          The first and second switches are advantageously arranged and interconnected so that it is not possible inadvertently to connect either capacitor across the line voltage, thus avoiding the possible destruction of the capacitors by the line voltage, regardless of the order in which the switches are actuated by the user.
