Abstract: FLAT ELECTRON BEAM ADDRESSED DEVICE           .            Abstract An evacuated envelope has a rectangular addressing section and a gun section at one edge of the addressing section.  The addressing section includes front and back walls in closely spaced, parallel relation, and a plurality of spaced, parallel support walls between the front and back walls forming a plurality of parallel channels.  The gun section extends across one end of the channels and includes gun structure which will selectively direct electrons along each of the channels.  In each of the channels are electrostatic guides to confine the electrons in a beam which is spaced from the walls of the channel and also guide the beam along the length of the channel. Electrostatic deflection permits selective deflection of the electron beams toward a target, e.g., a phosphor screen, which is disposed along the inner surface of the front wall.

Abstract: Application of Horst F. W. Arfert (Docket No. 6343-GB) For UNITED STATES LETTERS PATENT           On CONTAINER           ABSTRACT OF THE DISCLOSURE A container is provided and comprises a deformable metallic container body adapted to contain a product there-in and having a bottom wall and a side wall which has an upper portion terminating in an open end and a deformable metallic closure for said container body.  The closure has a main body portion adjoined at its outer edge by an annular flange with the flange having a roughly U-shaped cross-sectional configuration defined by a bight with an inner leg portion and an outer leg portion extending from opposite ends of the bight; and, the inner leg portion adjoins the main body portion and the outer leg portion is disposed radially out-wardly of the open end and terminates therebeneath.  One of the tubular upper portion and the inner leg portion is made of a relatively weak metal and the other of a relatively strong metal; and, at least one protrusion is provided in the strong metal portion and is convex into the weak metal portion with the weak metal portion having a corresponding cap disposed around the protrusion.  The closure is adapted to be removed by applying a rotational and lifting force against the outer leg portion causing the protrusion to de-form the weaker metal portion by defining a thread-like groove therein due to the rotational and lifting action en-abling easy removal of the closure.

Abstract: IMPROVED TWO-SPEED GEAR TRANSMISSION                     ABSTRACT OF THE DISCLOSURE            A two-speed planetary gear transmission including direct drive connectable by a clutch wherein the input and output shafts rotate together and a second gear drive namely overdrive or underdrive wherein one of the sun or ring gears are held stationary by a brake relative to the casing. A spring which causes engage-ment of the direct drive clutch exerts its greatest force when the clutch is engaged, it exerts a relatively high biasing force upon initial disengagement of the clutch under the action of an actuating device such as a servo-motor, to thereby assure initially a signif-icantly reduced level of torque transfer at the brake, to thereby provide a smooth gear transition.  The spring force then becomes significantly less when the brake is engaged.  The forces exerted by the spring in direct drive and by the actuating device in second gear drive bypass rotary bearings which are in motion at such times.

Abstract: DEVICE FOR MEASURING FILTERING PROPERTIES OF PAPER   PULP                 ABSTRACT OF THE DISCLOSURE    Filtering property of paper pulp is measured by the height of the filtrate column by periodically immersing a vessel having a gauge bottom into the pulp. The device for measuring filtering properties of paper pulp with the aid of the vessel having the gauze bottom, has a pneumatic system that immerses the vessel with the gauze bottom into or removes it from the pulp at a certain time interval, and also a follow up system for recording the result of each measurement of the filtrate level in the vessel by the mag-nitude of the hydrostatic pressure as measured by a bubbler. The device for measuring the filtering property of paper pulp is characterized in that the vessel with the gauze bottom consists of two communicating compartments having unequal cross section areas, the bubbler being installed in the smaller compartment. The device ensures high accura-cy of measurment of the filtering property of paper pulp in the course of time, that makes it possible to utilize the proposed device in a system for automatic control of the pulp grinding process.

Abstract: AUTOMATIC NUMBER IDENTIFICATION DEVICE                 Abstract of the Disclosure An automatic number identification device is used in a telephone system to enable a telephone central office to identify from which of two parties on a two party telephone service a call is originating and is coupled to a pair of telephone lines extended from the telephone central office to one of the parties being served by the two party telephone service.  A loop current sensor is connected in series relation with one line of the pair of the telephone lines forming a subscriber loop and detects when a specified loop current is present on the one line.  When the loop current sensor detects such a loop current, a control circuit, energized by power derived from the telephone lines  and coupled to the loop current sensor by a photo coupler, couples a resistive ground to both of the lines in the given subscriber's loop.  The control circuit has an on-time delay so that ringing signals on the subscriber's lines do not effect the operation of the control circuit and an off-time delay so that dialing pulses are not distorted.

Abstract: ABSTRACT      Granular solid material is dried in vertically extending annular chamber  formed between inner and outer cylindrical walls by a current of high temperature inert drying gas of high humidity passed downward through the material.   Material enters the chamber under gravity through a slot in the inner wall, which slot extends round the full periphery of the inner wall, and is removed from the bottom of the chamber by a variable speed discharge means, the rate of entry through the slot being governed by the rate of discharge from the bottom of the chamber so that the top of the column of material is of frusto-conical form.   The spent drying gas stream, less a quantity which is discharged, is used to dilute the products of a fuel in air, the high temperature mixture thus formed constituting the drying gas.   The said quantity discharged has a mass equal to that of the fuel and air forming said products of combustion.  An upward currrent of cooling air may be passed through the lower portions of the column of material.

Abstract: DIRECTIONAL COUPLER     Abstract of the Disclosure The invention is an improvement over the conventional branch guide directional coupler and gives better performance by provid-ing flatter coupling over a broader band.   A branch guide (line) directional coupler fundamentally is a four port electrical network. The invention improves the performance of the convention-al branch guide coupler by employing matching devices at the ports of the fundamental network. In most embodiments of the invention, it is contemplates that matching devices will be used at each of the ports and that all those matching devices will be of like construction.  However, it is not essential that a matching device be employed at every port nor is it  essential that all the match-ing devices be of like construction.  For example, in some embodiments of the invention, matching structures need be employed only at the output ports.  In the stripline and microstrip embodi-ments of the invention the matching device can be formed by a half wavelength open-circuited stub in combination with A quarter wavelength  transformer or by a short-circuited quarter wavelength stub in combination with a quarter wavelength transformer.  Although the  invention is described principally in stripline or microstrip form, the invention can also be embodied in waveguide or coaxial form.   1.
