Abstract: ABSTRACT OF THE DISCLOSURE A process is provided for removing an oxide scale from the surface of a metal article and a process for the manufacture of metal articles which controls oxide scale formation and descaling thereof.  A process includes providing an oxygen content of the thermal treatment atmosphere of at least 3.0%, by volume, after hot and cold forming to control the oxide scale formed.  The descaling process includes immersing the article in an electrolyte of an aqueous solution of at least one neutral salt from the group consisting of the chloride, sulfate and nitrate of an alkali metal or ammonium, adjusting and maintaining a pH of 2.0 to 3.5 and passing a low density electric current through the immersed article.  The article has an oxide scale substantially equivalent to an oxide scale formed at least in part in an oxidizing atmosphere of at least 3.0% oxygen, by volume.  The processes may include the step of immersing in a mild acid solution to substantially remove the scale.

Abstract: WRITING INSTRUMENT WITH MOVABLE CLOSURE     ABSTRACT OF THE DISCLOSURE    A writing  instrument with  a movable  closure, having a snap member for automatically closing the opening at the forward portion of the tapered front end of the writing instrument as the writing unit, within the writing instrument, is retracted.  The snap member includes, a cylindrical end and a plurality of resilient support segments extending from said cylin-drical end and terminating in covers attached to or integrally formed on the ends of the support segments opposite the cylindrical end.  These covers provide an airtight seal at the open front end of the writing instrument as they close upon each other in response to the forward movement of the snap member when the writing instrument is placed in its projected, writing position, the snap member is moved rearwardly, out of the open front end of the writing instrument toward the larger diameter section of the tapered front end.          Since the resilient support segments are no longer constricted  within  the  narrow  diameter  front  end opening, they expand radially, opening the covers to provide a passage through which the writing unit can pass.

Abstract: Abstract of the Disclosure A centerless grinding system comprises a driven grinding wheel, a driven regulating wheel, and a work rest blade for centerless grinding of a workpiece supported by the work rest blade between the grinding wheel and theregulating wheel; means for determining the rate of reduction of the workpiece radius while it is being ground; and means responsive to the rate of reduction of the workpiece radius for controlling the ratio of the power consumed in removing workpiece material to the rate of removal of workpiece material by the grinding wheel.  The regulating wheel is preferably fed toward the grinding wheel to feed the workpiece into the grinding wheel.  In a similar center-type grinding system, the work-piece is mounted on spindles or chucks which are movable toward the grinding wheel so that the workpiece can still be fed by the regulating wheel.  Workpieces longer than the axial dimension of the grinding wheel are ground in suc-cessive plunges along the length of the workpiece, with said ratio being controlled in each successive plunge.          To grind hollow workpieces, the regulating wheel or grinding wheel is placed inside the hollow workpiece.

Abstract: Abstract of the Disclosure Method and Apparatus for Making Braided Reinforced Hose A method and apparatus is provided for manufacturing a reinforced elastomeric hose.  Other reinforced hoses are prepared in individual stations for particular parts of the reinforced hose consequently requiring large amounts of manufacturing floor space.  Still other hoses that are made while utilizing small amounts of floor space do not provide a high strength braided reinforcement member.  A reinforced hose is produced by continuously braiding a tubular reinforcement member on a mandrel, progressively removing the reinforcement member from the mandrel, and at approximately the same axial location extruding a liner and cover onto the reinforcement member adjacent the mandrel.  After leaving the extruders, the formed hose is pulled at a linear rate faster than the hose is being produced in order to change the braid angle of the braided reinforcement member to a predetermined smaller braid angle.  As the hose leaves the extruders, it is pulled through a curing mechanism to cure the hose while the braid angle is at the predetermined angle.  Upon release and cooling of the hose, the hose rebounds to an optimum braid angle of approximately 54° 44'.  The braided reinforcement member provides the high strength characteristics while the extruding of the liner and cover at approximately the same axial location near the braiding mandrel minimizes the manufacturing floor space and reduce cost.

Abstract: ABSTRACT A capsule product and method for gradually releasing a medicament for absorption to a body of a warm blooded animal through the gastrointestinal system. The capsule has a fill material which includes a masticatory substance and a medicament that is dispersed throughout the gum. The medicament is of a type that is effectively and desirably released for absorption by the body through the gastrointestinal tract over an extended period of time. The msaticatory substance forms a supporting cohesive matrix for the medicament. The gelatin shell, usually formed from gelatin, water, and a plasticizer, is formed around the fill material into a capsule of a size and shape to be readily swallowable. Upon swallowing, the gelatin shell is rapidly dissolved in the gastrointestinal juices, while the fill material is substantially insoluble in the gastrointestinal juices. The matrix having the medicament dispersed throughout is subjected to substantially continuous random motion while contained within the gastrointestinal juices, while at body temperatures, and while under the influence of peristaltic movement for substantially varying the exposed surface area of the fill. As the surface area of the fill material is being changed, the medicament is gradually released from the exposed surface area for an extended period of time for ultimate absorption of the drug by the body.

Abstract: DRIVE FOR THERMAL PRINTING LIFT-OFF CORRECTION              Abstract of the Disclosure Ribbon (22) in thermal printing has an outer layer which adheres to printed characters at intermediate temperatures, lower than printing temperatures.  The printhead (7) has a column of electrodes (9) which sweep across the character area.  Lift-off is accomplished by the pattern control (40) controlling the current source (38) to provide rapid, square wave pulses displaced in phase 180 degrees at adjoining electrodes (9).  The high level of the pulses is about that of the level at printing, and the pulses are sufficiently rapid so that their net effect is to raise the outer layer ribbon (22) to the intermediate temperature.  At areas corresponding to underlines of characters, duration of the up period is longer.  Good, long term reliability is achieved by the significant erase level being very close to the print level.

Abstract: ABSTRACT     The present metering signal generator generates bursts of 12 or 16 kHz sine waves, the bursts having gradually varying edges in order not to produce audible clicks.  Due to offset of the amplifiers producing these edges the amplitude of the signal in the interburst time intervals may be relatively high and give rise to noise. This amplitude is therefore first made high so that it can be detected and then limited to a wanted value.  The invention also describes a comparator circuit and a modulator circuit used in the signal generator.

Abstract: ABSTRACT   The present invention relates to a process for the preparation of organic hydroxylamines as a result of the corresponding nitroderivative  being hy-drogenated in the presence of an inert solvent, a platinum catalyst, a nitrogen-containing base (in an amount of less than 10% by weight calcu-lated on the amount of nitro derivative) and a tri- or pentavalent organic phosphorus compound. It has been found that if only use is made of the nitrogen-containing base or the phosphorus compound the yields of isolated hydroxyl amine are significantly reduced in comparison with those obtained with the present process.
