Abstract: APPARATUS FOR RECORDING AND/OR REPRODUCING VIDEO AND AUDIO SIGNALS                    ABSTRACT OF THE DISCLOSURE     For providing nigh-quality reproduction of audio in a video tape recorder (VTR), the video and audio signals are recorded as first and second mixed signals in successive alternately  arranged  adjacent  first  and  second  parallel record  tracks,  respectively,  extending  obliquely  on  a magnetic  record  tape,  with  the  first  and  second  mixed signals being comprised of respective carriers of different frequencies  which  are  modulated  by  an  audio  signal  to constitute respective FM audio signals mixed with a video signal.  In a normal reproducing mode of the VTR, in which the tape is advanced at a normal speed corresponding to that used for recording, magnetic heads scan substantially along the adjacent first and second record tracks in succession for  alternately  reproducing  the  first  and  second  mixed signals therefrom, the FM audio signals are separated from the reproduced mixed signals and then are demodulated for obtaining   therefrom respective   alternately   reproduced portions of the audio signal, and the alternately reproduced portions are sequentially combined to reconstitute the audio signal therefrom.  In another reproducing mode in which the tape is advanced at other than its normal speed, the heads scan imperfectly along the record tracks so that the mixed signals  are reproduced therefrom with noise particularly when the heads are situated adjacent end portions of the tracks being imperfectly scanned,  and a noise compensating circuit is operative, in that other reproducing mode, for removing the noise from the reconstituted audio signal, for example,  by  muting  the  reconstituted  signal  during  the occurrences  of noise  or  by  replacing  the  noise  with  a predetermined signal level or with the level of a previously occurring signal which has been held.

Abstract: ABSTRACT OF THE DISCLOSURE        A wet ash remover which comprises a conveyor and a hydraulic transmission means with a controllable variable speed output.  Increase of ash load on the conveyor increases pressure of working fluid in the hydraulic transmission means, which is monitored and caused to act on a setting drive to vary the transmission output speed.  An electric motor operates the hydraulic transmission means which consists of a pump and a motor.  The housing for the pump can be varied in eccentricity with respect to its rotor for altering rate of flow of fluid in the pump, and thus through the motor, and therefore to change the output speed of the transmission means.

Abstract: ABSTRACT     A composition and method for preserving hops at room temperature utilizes the inherent properties of fermentable hydroscopic powders to retain essential volatile oils and hop acids for extended periods of time.  The composition is an intimate mixture of a fermentable hydroscopic powder such as maltose and dextrose and granulated hops having a low moisture content.  This com-position is prepared by reducing the size of the hops to a granular size and mixing the hops intimately with an equal or greater weight of hydroscopic powder.

Abstract: ABSTRACT           The invention is a support structure for that type of hopper bin having a conical base member with vertical symmetry axis.  The structure comprises a pair of concentric bands positioned symmetrically around the outside of the base member, each band being connected to the base member along at least a portion of its length.  Legs are positioned to extend from between the pair of bands to the ground to support the hopper bin off the ground, each leg being connected to both bands.  The bands may be connected together by spacer members and the legs may be connected to the spacer members by brace members to increase the strength of the support structure.  The support structure of the invention has a favorable strength-to-weight ratio in comparison to other hopper bin support structures.

Abstract: A COMPRESSOR VALVE            ABSTRACT OF THE DISCLOSURE    A compressor valve with annular valve members or rings instead of the usual spring-urged engagement of the rings with the valve seat, the rings are drawn into engagement with the seat by air or other gas passing through the valve in a direction reverse to that opening the valve.  Thus, on reversal of the flow, the rings are virtually instantly brought into engagement with the seat without the need for springs bringing the valve rings into closed state.  Both faces of the valve rings are identical.  When one face is worn, the ring can be turned over to utilize the second valve face.  The advance is in simplified structure, increased reliability and in longer operation life of the valve rings.

Abstract: ABSTRACT OF THE DISCLOSURE A shear head for removing weld upset from butt-welded rail before the latter is removed from the butt-welding machine, comprises a horseshoe-shaped back plate which carries three cutting tools.  An arm, which is pivotally mounted on one of the ends of the back plate and adapted to be latched to the other end to close the bight of the back plate, carries a fourth tool.  The shear head is stored at a location remote from a weld gap of the machine during welding.  After welding the shear head is lowered into the gap until its upper central tool abuts the top of the welded rail between the weld and the movable head, which causes the arm to be raised and latched to complete a continuous frame of cutting tools around the rail.          The shear head is then driven across the weld by the movable head to remove weld upset.

Abstract: Invention Abstract The invention is all apparatus for training of the human visual   accommodation   system.    Specifically,   the apparatus  is  useful   for  training  a  person  to volitionally  control  his  focus  to  his  far  point (normally infinity)  from a position of myopia due to functional causes.  The functional causes could be due, for example, to a behavioral accommodative spasm or the effects of an empty field.  The device may also be used to  measure  accommodation,  the  accommodation  resting position and the near and far points of vision.  The device comprises a number of optical elements arranged on a single optical axis (74).  Several of the elements are arranged in order on a movable stage (20) in fixed relationship to each other: a light source 30, a lens (32), a target (36), an aperture (42), (48) or (52) and second  lens   (58).   On  base   (18)   and  in  fixed relationship to each other are eyepiece (70) and third lens  (64).   Stage  (20)  generates  an  image  (72)  of target  (36)  and the stage is movable with respect to base (18) by means of knob 22.  The device is utilized for  the  various  training  and  test  functions  by following   a   series   of   procedural   steps,   and interchanging  the  apertures  as  necessary  for  the selected procedure.

Abstract: ACTIVATED ELECTRODES PRODUCED BY CONSECUTIVE DEPOSITION OF METAL LAYERS AND CARRIER SEPARATION     ABSTRACT A process for the manufacture of thin activated electrodes including a base metal, which can be iron, cobalt or nickel, with a good adhering active surface layer. Both the bass metal and the surface layer are galvanically sequentially deposited as separate layers on a removable electrically-conductive carrier. The surface layer is deposited as an activatable alloy including the base metal and a leachable metal, particularly zinc.  The galvanizing deposited layers are subsequentially separated as a unit from the carrier.  The alloy is activated by leaching the leachable metal therefrom before, during or after separation of the carrier.  Two activatable layers of alloy can be  deposited on the carrier with a layer of the base metal deposited between the alloy layers.
