Abstract: ABSTRACT           A wrap element and tip seal are disclosed for use in fluid apparatus of the scroll type which include a wrap element having a groove disposed within its tip surface of spiroidal configuration generally conforming to that of the wrap element.  A tip seal is disposed within the groove and comprises a relatively rigid strip of ma-terial having been wound about its longitudinal axis into a spiroidal configuration generally conforming to that of the groove, the strip of material having a cross section taken in a plane substantially perpendicular to its longi-tudinal axis wherein at least the radially outer surface thereof is convex in a radially outward direction.  This configuration for the tip seal has the advantage that it may be formed using conventional winding techniques wherein a certain amount of "twist" about the longitudinal axis of the strip of material is normally encountered.

Abstract: A PROCESS FOR THE PRODUCTION OF GRANULATES OF ORGANIC SUBSTANCES PRESENT IN THE FORM OF A MELT ABSTRACT OF THE DISCLOSURE    The organic substance present in the form of a melt is cooled below its solidification point in a twin-screw extruder so that it crystallises out. The crystallised material is then extruded through a breaker plate at the end of the screw extruder and further cooled. It is essential that the tempe-rature prevailing in the screw extruder, its rotational speed and the temperature of the breaker plate should be adjusted such that from 70 % to 99.5 % and preferably from 95 to 99.5 % of the material has solidified by the time it reaches the end of the screw, the non-crystallised liquid residue only crystallising out during the subsequent cooling operation. Accordingly, a small residue of melt is present during extrusion through the breaker plate. In addition, extrusion is facilitated if the breaker plate is kept at a temperature in the vicinity of the melting point of the material in question.     Le A 20 770

Abstract: PRECISION TIME TRACKING LINE GENERATOR   Abstract A display system line generator network having an error correction feedback loop which achieves high positional accuracy for both PPI and synthetic character and line data.          Digital reference position and relative beam motion data are fed into separate D/A converters.  The staircase effect at the output of the D/A that processes the relative beam motion data is eliminated in a constant current integrator.  The output of the integrator is combined with the reference po-sition signal in a summing amplifier and the summed signal is fed to a deflection amplifier.  A feedback circuit picks off the inputs to the summing amplifier and uses their comparison to synchronize time with beam position by compensating for errors due to component drift and aging.

Abstract: KICKOVER TOOL     Abstract of the Disclosure A kickover tool in which the body and actuator are formed of two elongate members having flat sides held in sliding confronting relationship with a tool carrying arm connected thereto and moved between retracted and extended position in response to relative movement between the body and actuator.    A locator key is provided which has spring means urging the key to extended position which is rendered ineffective by relative movement between the body and actuator and then either the same spring or another spring is effective to urge the key towards retracted position.    This invention relates to kickover tools.    In the past, many different kickover tools have been devised for landing and retrieving valves from side pocket mandrels.  While the tools have taken many different forms, they have generally been characterized by having a telescoping relationship between the body of the tool and the actuator of the tool and by a key on the actuator which engaged a shoulder in the well and which was rendered ineffective after the tool had been kicked over by shearing of a pin.    When pulling a valve, a substantial force may be required and various provisions have been made to keep the kickover arm in the kickover position while pulling a valve from the valve pocket of the mandrel.    Many of these tools have been successful and are in operation today.  However, they are all complex and usually fragile at one or more points.

Abstract: IMPROVED FLOTATION APPARATUS                 FOR CONCENTRATION OF MINERALS                  ABSTRACT OF THE DISCLOSURE    The invention relates to the concentration and benefica-tion of particulate matter by froth flotation and in particular to improvements in hydraulic-pneumatic flotation apparatus which contributes to efficiency of operation.  Such apparatus employs a constriction plate which separates vertically arranged flotation and aerating compartments.  A discharge duct may be used to extend through the aerating compartment and to open through the constriction plate centrally thereof.  Orifices in both the constriction plate and the discharge duct are in communication with the aerating compartment to provide a uniform dispersion of air bubbles in the flotation compartment.          To prevent build-up of non-float fraction on the constriction plate, the latter may be dish-shaped toward the discharge opening.  In an alternative embodiment, the discharge duct is omitted and the constriction plate is conically shaped with the apex uppermost.    To minimize development of circulating currents, baffle plates maybe used in the flotation compartment.

Abstract: Abstract:        A coating material is applied to drawn light-guide fiber in a manner which substantially prevents the inclusion of bubbles and which causes the fiber to be disposed substantially concentrically within the coating layer.  The lightguide fiber is advanced through a continuum of coating material, which extends from a free surface of a reservoir and through first and second dies that are arranged in tandem, at a velocity which causes air to be entrained in the coating material.  A pressure gradient is established between portions of the first die adjacent to its exit orifice.  The first die communicates with the reservoir and is spaced from the second die to provide a chamber which communicates with a pressurized supply of the coating material.  The pressurized flow sufficiently enhances the pressure gradient in the first die and establishes sufficient volumetric flow of coating material upwardly through the first die to cause any bubbles in the coating material on the advancing fiber to be removed by recirculating streamlines and to be moved upwardly into the reservoir. Not only is the coating in the fiber substantially free of entrained air as it leaves the second die, but the fiber is disposed concentrically within the coating because of a precentering effect of the first die and enhanced self-centering caused by pressure in the chamber.

Abstract: ADHESION PROMOTER FOR PRINTED CIRCUITS                        ABSTRACT     It is among the principal objects of invention to provide a composition and a method for improving the adhesion between a copper foil and a printed circuit substrate by the provision of an adhesion promoting copper oxide layer on the copper film.      The provision of copper oxide layers on the surface of copper films by immersion in a chlorite-hydroxide bath as conventionally conducted presents problems of safety and reproducibility.   This process is improved by employ-ing an oxidizing solution containing an alkali or alkaline earth metal chlorite at a concentration of from 100 grams per liter to complete  saturation, and sodium or potas-sium hydroxide at a concentration of from 5 to 25 grams per liter.  The process preferably forms an adhesion im-proving copper oxide film within commercially practical periods of time, on the order of 7 minutes or less, at practically low temperatures, on the order of from 80°F to 200°F, and preferably less than about 140°F.  The solution can be sprayed by conventional spray etchers.      The copper oxide films produced according to the most preferred conditions are brown in coloration  and provide adhesion values according to the standard peel test of greater than about 5 pounds per inch with contact times of from about 3 to about 5 minutes.
