Abstract: ARRANGEMENT ON A BUTTERFLY VALVE.             Abstract of the Disclosure.            Butterfly valve comprising a valve housing and a flap and two soft sealing rings retained by undercut grooves in the valve housing and from said grooves radially inwardly projecting sealing lips for engage-ment with the sealing surface of the flap.  By means of the two soft sealing rings which are separated by a flexible intermediate ring (18) of metal, the radial inner edge thereof is formed with two opposite directed sealing lips, a complete fluid sealing in both pressure directions is obtained.  In the event of destruction of the soft sealing rings caused by eventual fire in the valve, the pressure of the fluid will result in deformation or flexing of the intermediate ring, so that the one or the other of the sealing lips is pressed against the sealing surface of the flap and, thereby  obtaining a fire proof seal in both directions.          Said flexing or deformation of the intermediate ring is obtained by means of a weakened central cross sec-tional section provided by means of at least one, pre-ferably two circular grooves in the lateral opposing surfaces of the intermediate ring.

Abstract: Abstract of the Disclosure In a system for enhancing horizontal detail of a luminance signal, a horizontal peaking signal to be added to the luminance signal is cored with the depth of coring varied in accordance with a coring control potential.  To develop the coring control potential, the input luminance signal is capacitively coupled to the input of a signal translator comprising an inverting amplifier with a frequency selective negative feedback path providing the translator with a low pass characteristic and a signal delay substantially equal to the delay of a delay line employed in peaking signal formation.  An additional feedback path is provided by the emitter-collector path of a clamping transistor that conducts in response to sync pulse appearances to readjust the charge on the input capacitor, clamping the sync pulse peaks to a potential selected to establish a desired coring depth for black scene regions.  Amplifier gain is set to provide translator output swing establishing a desired minimum coring depth (e.g., zero) for peak white scene regions.

Abstract: ABSTRACT          An animal trap and ball detent trigger means there-for is disclosed.  The trap is of shaft and block construc-tion with the cable carrying block spring biased toward one end of the shaft. The shaft is longitudinally bored at one end thereof with a transverse bore intersecting the longitu-dinal bore for receiving ball bearings to be used for detaining the cable carrying block in a set position against a spring bias.  A plunger extends into the longitudinal bore for reciprocating between a position holding the ball bearings in a block detaining position and a position in which the ball bearings may be forced inwardly into the shaft to release the block.  The plunger and a trigger member are spring biased in a home set position.  The trigger member has a conically shaped end which rests in a correspondingly conically shaped trigger block with one end of the plunger in spring bias contact therewith.  The disturbance of the trigger member from its home position causes the trigger to rock in its conical recess and there-by apply a reciprocating lateral force to the plunger releasing the detaining force of the balls from the cable block.

Abstract: ABSTRACT.       To build up a screed coat on a roof surface, a granular ex-panded inorganic material is subjected to an atomized spray of an adhe-sive consisting of a solution of waterglass and a hardener therefor so as to form a thin film of adhesive on each grain of the material, and the spray coated granular material thus obtained is immediately convey-ed to and poured out on the roof surface. It is then spread over the roof surface and compressed to form a coherent layer constituting the screed coat. This may form a base for the superposition of insulating boards and a waterproof roof covering. The method is particularly useful in the renovation of deficient roofs originally built without a gradient towards outlets or gutters. Apparatus for carrying out the method comprises a device for causing the granular material to drop in the form of a cylindrical curtain, a rotational atomizer for spraying two component adhesive onto the surfaces of the dropping grains and a suction blower system for pneumatically conveying granular material to the spray coating station and, after treatment therein, to a pouring device on the roof.
