Abstract: ABSTRACT OF THE DISCLOSURE A novel device is provided for the stimulation and excitation of the human organs associated with hair follicles.  Such device  includes  a plurality of waveform generators,each generator operating at a different frequency within the range of 200 - 3000 cycles per second.  It also includes a selectively variable power amplifier and switch means for selectively and in combination coupling each of the generators to the amplifier.  A first electrode is driven by the amplifier, and a second electrode is maintained at ground potential from which the signals from the first electrode are referred.  Thus, the device produces modulated waveforms within a specified frequency range to amplify the stimulation and excitation effect to achieve practical results.  The stimulation and excitation permits blood circulation and soften and relaxes the galea.  This alternate contraction and relaxa-tion proceeds at a rate not obtainable by hard massage, or mechanical vi-brators.

Abstract: ABSTRACT OF THE DISCLOSURE  In order to provide a more accurate representation of aircraft pitch attitude for use in aircraft head up display devices, a circuit for generating a computed pitch signal responds to a longitudinal acceler-ometer and a vertical gyroscope within the aircraft wherein the computed pitch signal is generated by adding to the gyro pitch signal a correction factor computed by subtracting the value of the computed pitch signal from an inertial pitch signal derived from the longitudinal accerlerometer.  In order to compensate for the effects of aircraft acceleration on the longitudinal accelerometer signal, a computed acceleration signal derived from the difference between the longitudinal longitudinal accelerometer to generate the inertial pitch signal.  To further compensate the systems for long term errors in the gyro pitch signal, the combined longitudinal acceleration and gyro pitch signal is subtracted from a differentiated air speed signal and the resulting difference signal is integrated over time to generate an acceleration correction signal that is applied to the computed acceleration signal.

Abstract: CIRCUIT AND METHOD FOR REDUCING POLARIZATION         CROSSTALK CAUSED BY RAINFALL            Abstract of the Disclosure A circuit for reducing the effects of polarization crosstalk occurring on a first RF signal due to a second RF signal, wherein the first and the second RF signals are two approximately orthogonally polarized RF signals having essentially the same frequency.  The circuit comprises a first antenna and a first signal path (including RF and IF sections) for the first RF signal and a second antenna and a second signal path (including RF and IF sections) for the second RF signal.  A first coupler diverts a portion of the signal on the second signal path into a first network comprising the series combination of a variable attenuator and a variable phase shifter.  A summing circuit sums both the signal on the first signal path and the signal output from the first network with the result that the undesired signal on the first signal path is reduced.  A logic circuit, responsive to the magnitude of one of the RF signals, controls the first network according to a predetermined relationship.     - i -

Abstract: ABSTRACT OF THE DISCLOSURE The present invention relates to a support structure for shelves suitable for ready changing of the height and the relative distance between individual shelf boards. The support structure consists of vertical members adapted to be fastened to another ver-tical structure and of brackets adapted to be moved along the vertical members and to be held therein by frictional locking forces. each vertical member has a uniform cross section in the shape of a rectangular, assymetrical channel comprising a web, a base flange provided with means for attaching it adjacent to a wall and an outer smaller-width flange provided along its outer with a re-entrant first guide parallel to the plane of the web. Each bracket is in the shape of a rigid angle plate having an inner end and an outer end, the inner end being positioned in a vertical member with its axis perpendicular to the plane of the base flange. The load acting on the shelf creates horizontal forces between the bracket and the channel which prevent slipping down of the bracket by inherent friction forces acting on the edges of the bracket.

Abstract: FIBER CAN, METHOD AND APPARATUS     Abstract of the Disclosure A can is provided that includes a tubular can body having a separation line extending from one end to the other with a label over it to prevent the separation line from opening during shipment or storage.  The label includes a partial circumferen-tial collar cut extending from one edge of the label material toward the other edge and having a termination point spaced from the other edge of the label.  According to one method of manufacture the cuts in the label are formed by severing the label stock just before it is wound upon the fiber body during the manufacture of the tube from which can length pieces are cut.  The knife is moved rectilinearly parallel to the tube with the same component of velocity that the label has parallel to the axis of the tube thereby providing a cut in the label at right angles to the can axis.

Abstract: ABSTRACT OF THE DISCLOSURE           A finishing welt, comprised of a reinforcing polyethylene rod surrounded by a fabric scrim and an outer encasing layer of polyvinyl chloride, is formed in an extrusion-embossment method and apparatus.  The method includes feeding a composite preform, consisting of the polyethylene rod and the scrim, first through an essentially key-hole shaped passageway in a core pin of an ex-truder crosshead and then into a chamber within the crosshead where plastic material under pressure flows onto the preform.  Immediate-ly thereafter, the preform is conveyed through an essentially key-hole shaped orifice, where the welt is formed by extrusion.  Next, the opposed sides of the welt are sequentially embossed as the welt is conveyed over external peripheral embossing surfaces of two spaced rollers.  The resultant welt is essentially key-hole shaped in cross-section, with the scrim surrounding the rod within the enlarged head portion of the welt and extending into the smaller depending flange portion.  As a result of the extrusion step, the outer encasing layer of polyvinyl chloride is bonded through the scrim in the welt flange; and as a result of the sequential embos-sment, the outer surface of the welt is free of any significant longitudinal rib.

Abstract: HYDROFORMYLATION OF OLEFINIC COMPOUNDS          Abstract of the Disclosure Rhodium catalyzed hydroformylation of olefinic compounds is essentially effected in the presence of a secondary phosphine oxide of the general formula (I) below in an amount of at least one mole per gram atom of rhodium.  This precludes the thermal degradation of the rhodium catalyst in the hydroformylation stage as well as in the distillation of the reaction products.          The secondary phosphine oxide has the formula:                    (I) wherein, in the formula (I), R1 and R2 may be the same or different, and each represents a substituted or unsubstituted hydrocarbon residue containing not more than 20 carbon atoms.  The phosphine oxide of the general formula (I) maintains the catalytic activity over a prolonged period of time and prevents essentially metallic rhodium sticking to the vessel walls during distillation of the reaction products from the reaction mixture, and consequently re-cycling of the catalyst is easier and the hydroformylation pressure can be lowered.
