Abstract: Abstract An internally generated raster scanning circuit includes self correction for pincushion distortion by multiplying the horizontal parabolic wave form by the vertical saw-tooth wave form.  The multiplier is biased to provide the required 180° phase shift at the midpoint of the waveform.  The multiplied signals are coupled back to an input of the existing power amplifier and a corrected current is then supplied to the vertical yoke coil, requiring no added reactor transformer.  The balance or ratio of the top and bottom correction currents can be adjusted as required by a simple control in the multiplier circuit.

Abstract: ABSTRACT The invention provides an electronic drainage system for draining of liquid and gases from a cavity such as the pleural cavity, while providing means for making any of a number of measurements and for generating accurate and easily comprehendable readings without the need to resort to manometer tubes or other fluid gauges.  The invention contemplates both a comprehensive system for controlling the flow of fluids from the pleural cavity or the like, through a simple hook-up between the patient and a suction system, while monitoring any of various physical characteristics and indicating such measurements on readily readable displays, such characteristics including: effluent temperature, effluent volume, effluent weight, patient negativity pressure, maximum negativity, patient air flow rate, suction, suction air flow and the like.  A preferred circuit for performing the foregoing functions includes various transducers which can further be used to regulate the desired suction setting and to measure various air flow rates while providing automatic and precise control of the regulated parameters, and circuitry connected to an effluent collection chamber for repeatedly measuring and emptying the chamber to provide the drainage function as well as the measurement functions of the fluids associated therewith.  Multiplex circuitry is preferably provided for automatically reading the various measuring devices and for displaying relevant information in an easily understandable form.  The invention on a less comprehensive scale comprehends a combination of electronic and mechanical components for measuring and displaying values for air flow, suction, patient negativity and maximum negativity.  The invention in its preferred form includes fluid contaminatable portions which are disposable after use.

Abstract: Abstract of the Disclosure An apparatus for detecting a ground fault occurring in a power system which furnishes an AC power from a variable-voltage variable-frequency power supply to a load via a voltage transformer.  The apparatus compares a zero phase sequence current with a reference value and, upon detection of occurrence of a ground fault, produces an output signal representing the ground fault.  Prior to such comparison, the zero phase sequence current is so processed as to be independent of the frequency of the power system or the reference value is so processed as to be dependent on the said frequency.

Abstract: ABSTRACT OF THE DISCLOSURE A relatively short broad band monopole coaxial antenna is provided with a center conductor and an outer radiator.  The antenna is mounted above a ground plane and comprises a bare outer radiator portion adjacent the ground plane and a portion remote from the ground plane which is covered with a variable thickness microwave absorbent material,  The signal to be transmitted is applied to the base of the monopole antenna adjacent the ground plane.  Non-radiated signals propagate up the antenna.  The high frequency components are absorbed by the microwave absorbing material.  A tip matching network and a base matching network are coupled between the outer conductor and the ground plane for attenuating and matching the low frequency components of the non-radiated signals.  The resulting monopole coaxial antenna has no undesirable reflec-tions and has the appearance of infinite effective length antenna.

Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus and method for airplane deployment over water  of  survival  kit  apparatus  is  provided.   A  pair  of deflated,  inflatable rafts are contained in a rigid container shell having a removable tail cone.  A stabilizer drogue may be used to longitudinally stabilize the container prior  to tail cone  release  and  assist  with  the  tail  cone  removal  after release.   The tail cone is mechanically released and removed from  the  container  shell  at  a  predetermined  time  after deployment from an aircraft,  thereby permitting the container shell contents to be removed.  The life rafts are contained in the  container  shell  so that  one  life raft having associated with it aerodynamic braking means is released after the tail cone has been removed, with the container and second life raft continuing their  trajectory downwards.   The rope  joining the two life rafts is continuously paid out as the first life raft falls to the water and the container with the second life raft therein  continues  its  trajectory.   The  second  life  raft  is removed  from  the  container  shell  mechanically  after  the container  shell  contacts  the  surface  of  the  water.   The apparatus and method of the invention results in the pair of inflated  rope-joined  life  rafts  being deployed on the water surface at spaced locations.

Abstract: ABSTRACT       In order to rapidly load tights on a stocking finishing machine specially equipped with a pneumatic inverter, a carousel is used that has several horizontal arms which in their loading position are coplanar to the tubes of the inverter and which are intermittently turnable with a stop in abutted and aligned position to said tubes of the inverter.         Each arm of the carousel is equipped with two flat forms to support the body of the tights which are slipped over them manually.  Two spacer elements stretch the elastic waistband of the body into a rectangular shape and, in this position, transfer and invert the body of the tights onto the tubes of the inverter, while the legs of the tights are aspirated into the tubes.  A horizontal rail, extending to above the tubes of the inverter in their loading position, allows the travel of said spacer elements.

Abstract: Abstract of the Disclosure An improved easy opening container and is disclosed of the type wherein an opening tab is attached to a wall of a can end closures at a fulcrum adjacent a primary score line. The primary score line circumscribes a pour opening panel except at a hinge area. The forward portion of the opening tab is adapted to depress the pour opening panel into the container to expose a pour opening when the opening tab is pivoted about the fulcrum. The opening tab is attached to the wall by means of a rivet. One secondary score line intersects with the primary score line and projects away from the pour opening panel on one side of the rivet and another secondary score line, also intersects with the primary score line, and projects away from the pour opening panel on the other side of the rivet. In this manner, after the primary score line is severed and the pour opening panel is depressed, the opening tab may be retracted from the vicinity of the pour opening panel by severing the secondary score line so as to provide easy removal of the contents of the container and to expose an underportion of the wall for the reading of promotional indicia. In the present embodiment, a region of the wall contiguous with the pour opening panel and further defined by a secondary score line may be provided such that after depression of the pour opening panel, the pour opening panel, and the region attached thereto by means of a hinge area by be severed from the container end along with the opening tab.
