Abstract: ABSTRACT OF THE DISCLOSURE          HORN ANTENNA AND MIXER CONSTRUCTION FOR MICROWAVE RADAR DETECTORS        A horn antenna construction,  particularly for use in  microwave  radar  detector  circuits,  comprises  a molded  horn  element that is open at its bottom  side, with  a ridge molded into its flared top  surface,  and being  electrically  conductive at least  at  microwave frequencies  such as in the X-band and  K-band.     The open  bottom of the horn element mates to a  conductive upper  surface  on a mounting board,  and the  horn  is drawn   down   onto  the  mounting  board so  that  its upper  surface forms the bottom of the horn.  Thus, the ridge  is brought into physical and electrical  contact with  a feed strip formed in a microstrip board on  the mounting  board, that  has a  mixing  diode  or  diodes associated therewith.  by this construction, there is a positive  and  dimensionally stable association of  the throat of the horn and the ridge to the feed strip  and the  mixing  diode(s),  without  the necessity  of  any solder,  inserted connectors or mounting pins,  or  the provision  of  any tuning posts or  screws.   Moreover, very efficient energy conversion, and thereby increased sensitivity,  is  assured because the  horn,  the  feed strip and certain matching and terminating stubs on the microstrip  board  assure  good isolation  between  the mixing  ports  and  low  energy  loss  at  the   mixer.

Abstract: 31 ABSTRACT: A receiver for receiving a signal modulated on an RF-carrier, comprising a pair of signal paths arranged in parallel between an RF-input and a superposition circuit and including, arranged in succession, a pair of first mix-ing stages for mixing down the frequency of the received modulated RF-carrier to a low frequency, mixing signals being applied in a phase quadrature relationship to these first mixing stages from an RF-tuning oscillator, a pair of filtering elements for signal selection and a pair of second mixing stages for up-converting the frequency of the selected modulated carrier, mixing signals being applied also in a phase-quadrature relationship to these second mixing stages from a fixed LF-oscillator, these second mix-ing stages being connected to inputs of the superposition circuit, the superposition circuit comprising an adding or a subtracting stage arranged between outputs of the two signal paths and producing a first output signal. An amplitude and phase balance between the two signal paths is established by an amplitude and phase control of the signals in the two signal paths in dependence on the amplitude and phase of the image interference in the output signal of the superposition circuit. The image interference is measured according to the invention on the basis of the image inter-ference component at a predetermined reference frequency, more specifically the carrier frequency. The amplitude of this image interference component is measured by detecting the image interference component phase-synchronously, the reference frequency being the detection carrier, and the phase of this image interference component is measured by detecting the image interference component synchronously by means of a detection carrier whose phase is shifted through 90° relative to the reference frequency. The of necessity equal frequency position between the reference frequency and its image interference component is obtained by means of frequency mirror-inversion.

Abstract: ABSTRACT OF THE DISCLOSURE        METHOD OF PREPARING CATIONIC TERPOLYMERS             AND PRODUCT DERIVED THEREFROM      Novel high molecular weight water soluble terpoly-mers derived from ethylenically unsaturated monomers with pendent amide groups, carboxyl groups and ester groups containing a 2-hydroxypropyltrimethylammonium-chloride moiety are flocculants of high efficacy.  These terpolymers may be prepared by reaction between glycidyl trimethylammoniumchloride and copolymers of acrylamide and acrylic acid.  The compositions are derived from acrylamide-acrylic acid copolymers and may contain as little as 4-7% of chain segments containing the 2-hydroxypropyltrimethylammoniumchloride moiety connected to the polymer backbone via an ester linkage.    The acrylamide-acrylic acid copolymers may be obtained by any known process entailing either copoly-merization of the corresponding monomers or controlled hydrolysis of either polyacrylamide or poly-acrylonitrile.  The terpolymer formation is achieved either by reaction between such copolymers and glycidyltrimethylammoniumchloride, or by conducting the polymerization of the comonomer mixture in the presence of glycidyltrimethylammoniumchloride at conditions at which reaction between this chloride and carboxyl groups occurs.  The terpolymers may also be obtained by reaction between 3-chloro-2-hydroxypropyl-trimethylammonium chloride and copolymers of acrylamide and the alkali metal salts of acrylic acid or methacrylic acid such as sodium or potassium acrylate or methacrylate.

Abstract: ABSTRACT OF THE DISCLOSURE     A slider applicator has a stopper attached to an end of a slide rod slidably mounted in a pivotable casing for movement parallel to a feed path along which a slide fastener chain is fed through a slider supported on a slider holder.  When the stopper is displaced for a prescribed distance by box and insertion pins on the slide fastener chain, a micro switch is actuated to operate an air cylinder for angularly moving the casing to lift the casing out of engagement with the box and insertion pins, which are now allowed to move with the slide fastener chain past the stopper.  In the event of improper positioning of one of the box and insertion pins, adjacent endmost coupling elements are jammed in a slider to thereby prevent the stopper from being displaced for the prescribed distance.          A sensor switch is then actuated to signal such improper positioning of one of the box and insertion pins.
