Abstract: ABSTRACT OF THE DISCLOSURE     A voice actuated control system suitable for use on a computer numerically controlled (CNC) machine tool includes a pair of radio frequency transmitters and a pair of radio frequency receivers, one of the radio frequency receivers and one of the radio frequency transmitters being located at the machine tool site and the other radio frequency receivers and radio frequency transmitter being carried by the human ma-chine tool operator.  Operator-spoken commands are transmitted through the operator's transmitter to the machine tool receiver which outputs an audio signal to a voice interpreter that con-verts the received voice commands into digital signals which are transmitted to the CNC machine tool control system to con-trol machine tool operation.  Digital signals generated by the CNC machine tool control system, either in response to received operator commands or in accordance with variations in machine tool operating conditions, are converted by a speech synthe-sizer into synthesized audio signals representing speech phrases indicative of machine tool operating conditions.  The speech synthesizer audio signals are transmitted to the operator to audibly inform him or her that the previously transmitted voice commands have been received or that further instructions are required.

Abstract: INDUCTION HEATER ARRANGEMENT    FOR FORGING BAR STOCK                 Abstract An induction heating arrangement for heating an end length of a forging bar following the cut-off therefrom of a previously heated and forged end length is arranged to heat the end length to a uniform temperature despite the existence of a residually heated terminal end from the previous heat.  The heating arrangement has an induction heating coil with a longitudinally extending axial passageway therethrough for receiving the bar length to be heated by insertion into the passageway through the feed-in end thereof. A reciprocable flux diverter or robber ring is moved into the open other end of the coil passageway to surround the residually heated terminal end of the inserted bar end length, during a predetermined portion of the total coil heating cycle, to divert the flux from and prevent it from penetrating and heating the residually heated terminal end, whereby the inserted bar end length is evenly heated throughout its entire axial extent to the desired uniform forging temperature.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention provides a method for preventing polymer scale build-up on the reactor walls, in particular, in the suspension or emulsion polymerization of an ethylenically unsaturated monomer effective even in the cases where the polymerization initator is a monomer-soluble organic perox-ide having a relatively high solubility in water which hith erto has been not used due to the difficulty in preventing polymer scale build-up despite the superior quality of the polymer product obtained therewith. The method comprises coating the reactor walls in advance with an aqueous coating composition comprising (I) an organic dye of sulfonic or carboxylic acid type in the form of an alkali metal or ammo-nium salt and (II) an aqueous colloidal dispersion of an in-organic material and then drying the coated surface.

Abstract: ABSTRACT OF THE DISCLOSURE      A rooftop parapet, for a thermally-insulated curtain-walled building, comprises:  a parapet base; a thermally-insulated curtain wall having an upper part spaced apart from the parapet base with a gap therebetween; a moisture-proof sheet covering the gap; a thermally insulating material laid over an upper edge of the paraet base, the moisture roof sheet, and an upper edge of the curtain wall; a waterproof sheet superposed over the insulating material; and a coping plate superposed over the waterproof sheet.  Either the moisture-proof sheet or the waterproof sheet has a sagged portion so that the coping plate can follow the deflection of the curtain wall's upper part due to loading of wind pressure effected on the curtain wall.  The moisture-proof sheet serves to prevent the thermally insulating material from absorbing moisure inside the building, while the waterproof sheet serves to prevent dewdrops on an inner face of the coping plate from coming down to the insulating material.

Abstract: Abstract.   A method and apparatus for omnidirectional reading of data fields is provided.  Such data fields contain at least one data track containing contrasting printed indicia and a PIC pattern.  The PIC pattern indicates the position and orientation of the data tracks.  The data field appears at an image window which is scanned by an opto-electronic scanner operating in a point raster scan and individual raster point signals are generated which correspond to the light/dark values of the original image. The signals are stored as a corresponding image arranged in row and column form.  A search raster then probes the stored image in a sequence of rows, but the rows of the search raster scan the stored image at a predetermined search angle relative to the rows of the stored image itself upon each pass of the search raster.  The video signal produced by each pass of the search raster is examined for the presence or absence of the PIC pattern.  Upon recognition of the PIC pattern, the orientation of the data tracks is determined and then the data field is read either in the direction of the data tracks or at right angles to them, and the information they contain is decoded.

Abstract: Application Of:  Peter JO Gualtieri and Roger T. Goulet For:  Downflow Air Filter Construction and Methods For Air Flow Adjustment and Leak Testing Thereof Abstract Of The Disclosure A HEPA-type, downflow air filter module is disclosed, having a damper supported upon a hollow tube for adjustable movement relative to an opening through which air enters the enclosed chamber or plenum above the filter media.  The hollow damper support tube is axially aligned with a passagaway between upstream and downstream sides of the center board which conventionally separates the media normally sealed by a plug which may be removed from the downstream side of the module for measuring and adjusting air flow into the module, as controlled by the position of the damper which may be adjusted while air flow is being measured.          The filter construction also permits leak testing of the filter by injection of test smoke from the downstream side, through the center board passageway and hollow damper tube, with simultaneous monitoring of the smoke concentration on the upstream side, thereby insuring that the desired level of smoke concentration on the upstream side of the media is reached prior to scanning the downstream side for the presence of particles to detect leaks.

Abstract: ABSTRACT OF THE DISCLOSURE        A semiconductor hot electron transistor of the tunneling emitter type has an emitter layer, a first insulating layer, a metallic or metallically conductive base layer, and a collector layer.  The emitter layer is formed by an inversion layer generated in the channel region of a field effect transistor integrated on a semiconductor substrate between the source and drain regions of the field effect transistor.  The base layer of the hot electron transistor includes at least one portion of the gate electrode of the field effect transistor.  The collector layer is formed by a metallically conductive layer and a second insulating layer, the second insulating layer being disposed between the base layer and the metallically conductive layer.          The hot electron transistor is operated by forming a depletion zone between the source and drain region of the field effect transistor by switching a voltage source connected to the gate electrode of the field effect transistor (which forms the base layer for the hot electron transistor), the voltage source alternating between two values one of which is above the threshold voltage for the field effect transistor.  The hot electron transistor may also be operated by varying the source voltage as a function of an input signal.
