Title: Ring transformer for resistance butt welders
Inventor: PATON BORIS E
IPC: H01F30/16
Filed: 1979-03-20
Granted: 1982-04-27
Abstract: ABSTRACT OF THE DISCLOSURE       According to the invention, the ring transformer for resistance butt welders comprises a plurality of sections, each composed of a non-closed magnetic core, a part of the primary winding and a part of the secondary winding.  Each section is so arranged with respect to the other sections that the end faces of its non-closed magnetic core are in contact with the end faces of the two adjacent sections, whereby the non-closed magnetic cores of all the sections make up a closed magentic core of the transformer.  The primary winding of each section is connected to those of all the other sections so that they all make up the primary winding of the transformer.         The secondary winding of each section is connected to those of the other sections so that they all make up the secondary winding of the transformer.

Abstract: ABSTRACT OF THE DISCLOSURE     In order to release gas dissolved in a liquid such as beer the liquid is injected as a spray into an agitation chamber having a liquid outlet at one end and a gas outlet at the other end,  The gas outlet is controlled by a valve.          Electrical contacts are provided within the chamber for monitoring the liquid level therein.  When the liquid in the chamber rises to a level which covers at least one of the con-tacts the gas outlet valve will be closed and liquid continues to enter the chamber until prevented from so doing by the gas cushion.  When the liquid level drops below the electrical contacts the gas valve is opened.

Abstract: ABSTRACT OF THE DISCLOSURE           The application discloses an identity card con-sisting of a plurality of layers, of which the cover layers are highly transparent films and the layers of the card core are films of moderate to low transparency, as a result of added pigment.  One core layer carries informa-tion, which can be read directly, if desired,  above a security print, while the other core layer has an addi-tional security marking, such as a guilloche print, a marking which can be read optically only with the aid of a special lamp, or a piece of magnetic tape.  All the layers consist of polymers which can be fused together to form a laminate which is fused together like a mono-lithic block and which does not have any interfaces which allow a mechanical, thermal or chemical separation.

Abstract: Abstract of the Disclosure A locking cap for a threaded filler neck includes a closure member for engaging and closing the neck, a shell providing a hand grip and including a key-actuable lock, and a race disposed for rotation between the shell and closure.          The race includes axially inwardly opening pockets, and the closure includes flexible pawl fingers for engaging the pockets to provide a driving connection between the closure and race which is positive in the cap-removal direction and torque-limited in the cap-advancing direction.  The race also includes a set of peripherally spaced, radially inwardly projecting teeth, and the shell is molded to provide a pair of flexible drive fingers for engaging the peripherally spaced and radially inwardly projecting teeth to provide a driving connection between the shell and race which is positive in the cap-advancing direction and torque-limited in the cap-removal direction for free ratcheting of the cap when it is in position on the filler neck and locked.  A lock-controlled bolt member mounted for rotation with the shell is movable by the lock to a cap-removal position.  The bolt member engages driving teeth provided within the closure member.  The driving teeth are formed such that rotation of the shell in the cap-advancing direction, after the lock has been returned to the cap-locking position, cams the bolt out of engagement with the driving teeth.

Method of manufacturing cooling blocks for semiconductor lasers, in which the rounding-off radius of the line of intersection between two surfaces of the cooling blocks must have a very small value. In the method, two bodies to be formed into cooling blocks are each provided with a flat surface and these bodies are secured together with their flat surfaces by means of a curable adhesive. One side of the bodies connected together is subjected, trans-versely to the two surfaces connected together, to a machining treatment so as to obtain a further flat surface, in which machining treatment deformation and burring of the bodies near the line of intersection to be formed is avoided due to the presence of the cured adhesive, and a line of intersection having a rounding-off radius of only a few microns is formed.

Abstract: Abstract The present  invention relates to the  field of  insulating board  products,  and  in  particular,  to  insulating  boards  used  in built-up roof construction.  When constructing a built-up roof moisture within the various  layers making up the built-up roof can,  if not vented,  result in accelerated  failure of the  roof membrane.   The present invention provides an insulating board having moisture venting channels impressed in the lower surface thereof.  The channels of the boards are interconnected with one another by rabbeted portions along the perimeter of each board.   Thus, a series of such boards adhered to either the roof deck or an old failed roof membrane, provides a means for venting moisture while simultaneously providing a smooth, stable surface on which a further new roof membrane may be adhered.

Abstract: ABSTRACT OF THE DISCLOSURE    Nonwoven disposable wiper intended primarily for industrial applications and having a reduced tendency to accumulate metal chips or other small, sharp foreign objects.  The wiper results from a combination of a meltblown microfiber web laminated to at least one web of interconnected aligned split filaments, such as a fibrillated thermoplastic film or foam.  The combination is pattern bonded and includes a surfactant for improved wiping properties.          The combination of the split flamentary web and microfiber web results in increased safety since injuries due to metal chips picked up by the wiper material are minimized.  This is accomplished without significant deterioration of the wiping properties of the meltblown material.

Abstract: ABSTRACT OF THE DISCLOSURE A digital pressure measuring system with nonlinear resolution is disclosed.  The system includes a capacitive pressure transducer with a pressure variable sensing capacitor and a substantially invariable reference capacitor.  The capacitors of the transducer are excited by  out-of-phase signals and their outputs combined at a summing junction.  The output of the summing junction controls the incrementation of a counter whose output is converted to a nonlinear negative feedback signal.  A closed loop is formed by applying the feedback signal to the summing junction through a feedback capacitor. The counter is incremented in a direction to null the  loop such that its output is representative of the measured pressure.
