Abstract: Abstract A dispenser cathode is fabricated by covering a reservoir of electron emitting material with a perforated metal foil having an appropriate pattern of pore-sized apertures thereon for providing uniform electron emission from the cathode surface. The electron emitting material is in the form of a pellet of barium oxide impregnated with a wax or resinous material to minimize chemical reduction of the barium  oxide in air. The impregnated barium oxide pellet is sandwiched between the apertured foil and a support structure to which the foil is welded. During tube bake-out or subsequently during cathode activation, the wax or resinous material evaporates and barium oxide migrates through the apertures to cover the surface of the foil in a uniform manner.  The barium oxide pellet is obtained from the carbonate and is wax impregnated prior to assembly into the cathode.  Thus no carbonate is present at the tube bake out or cathode activa-tion stages, thereby avoiding the carburization of electron emitting metal surfaces.

Abstract: ABSTRACT OF THE DISCLOSURE A moving vehicle power distribution apparatus includes power  signal  and ground signal rails provided along a roadway track including a track switch.  As the track switch is moved to pass the vehicle to selected roadway tracks,  the  signal  and power  rails  can become misaligned and damage current collectors carried by the vehicle that travel along these rails.  Coupling members having  interdigitated members  extend between  the  rail sections to control the movement of the current collectors as the vehicle travels through the track switch.

Abstract: ABSTRACT OF THE DISCLOSURE           A high resolution light pen is disclosed for use with graphic displays.  More particularly, a light pen is disclosed having a collimation tube slidably mounted within a housing.  The collimation tube includes an axially extending channel having a non-reflective surface.  A photodetector is fixably mounted within the housing aligned with the channel.          A lens is mounted adjacent the front end of the channel and has a focal length equal to the spacing between the lens and an aligned pixel of the video screen.  By this arrangement, all light rays emanating from an aligned pixel and passing through the lens are refracted axially along the channel and directed to the photodetector thereby maximizing the input thereto.          The subject invention further includes a new and improved discrimination circuit for determining valid input signals from the light pen and producing an interrupt signal at a time substantially independent of the amplitude and slope of the input signals.  In accordance with the subject invention, each input signal is compared with an upper threshold level to determine if a valid signal has been detected.  In addition, each input pulse is compared to a lower threshold level for timing purposes.  The result of the comparison with the lower threshold level is delayed and supplied to a gate means with the output of the first comparison.  The gate functions to produce an output signal when the results of both comparisons received are simultaneously positive thereby indicating the validity of the input pulse at a time independent of the amplitude of the pulse whereby the effects of jitter are reduced.

Abstract: ABSTRACT OF THE DISCLOSURE          A substructure for an oil derrick comprising a base frame, a top frame and an intermediate bifurcated support frame consisting of a pair of horizontally extending traveling frames. A linkage network of swingable leg members intercouples the base, traveling and top frames for movement in parallelism between collapsed and elevated conditions of the substructure.  In the collapsed mode the frame members are positioned in an adjacent relationship for presenting a low profile to a flatbed truck which allows a portable oil rig to be easily shifted onto the top frame and into alignment with the oil wellhead therebelow.  A block and tackle assembly operably engages the traveling frames and is coupled to the derrick hook carried by the traveling block of the oil derrick.  Upon operation of the latter the swingably mounted traveling frames move towards each other causing an elevation of the top frame so as to present a working space between the ele-vated oil derrick and oil wellhead.  The traveling frames are locked one to the other to maintain the top frame at its elevated position with collapsible end sway braces precluding lateral shifting of the top frame and oil rig thereon.  To relocate the rig at another site, the traveling frames are unlocked causing a load induced, downward movement of the swingable leg members and associated frames toward their collapsed position with a hydraulic buffer assembly regulating the speed of movement of the traveling frames and thus the collapsing speed of the entire substructure.

Abstract: A b s t r a c t Static power converter Static power converters are devices for convert-ing electrical power, and comprise one or more sets of diodes, or sees of thyristors, and, as appropriate, a power-converter transformer, reactors, switching units, and further auxiliary devices.  They are designed, inter alia, as rectifiers, inverters, and converters, and are used for operating electrical machines.  During operation, static power converters are subject to current harmonics, which lead to undesirable feedback perturbations affecting the current-supply system.  If no protective measures are adopted, dangerous overvoltages can occur in the process of switching off inductive loads, and both these loads and the semiconductor components of the power converters are particularly endangered by such overvoltages.  In order to reduce these undesirable effects, a power-converter bridge (20) of a converter (21) possessing a direct-current intermediate circuit, intended for connection to a machine representing an inductive load, on the machine side, via machine phase-conductors (U,V,W), e.g. for connection to an asynchronous machine possessing a slipring-rotor (23), is designed with thyristors in the bridge arms, with facilities for turning these thyristors off. The thyristors are operated at a comparatively high switching frequency, so that the power-converter bridge (20) supplies an alternating current which is comparatively near-sinusoidal, and which exhibits a low harmonics con-tent.  Following the turning off of the thyristors, the energy stored in the rotor windings of the a synchronous machine (23) is temporarily stored in the capacitors (5) of an overvoltage protection unit (22), these capacitors (5) being connected to the alternating-voltage terminals of the bridge circuit (20), so that no imper-missible over-voltages occur.

Abstract: Abstract of the Disclosures The present invention discloses a maximum pressure control device for the brake cylinder pressure that is to be supplied to a brake cylinder and this device can consist of two separate pressure control devices or be constructed as a unified, reversible pressure control device.  The selection of one of the active pressure control devices or changeover of the switchable maximum pressure control device results from a main brake line pressure acting against a spring loaded control piston which, depending on the main brake line pressure, can switch off the pressure control function of the maximum pressure control device for the low (service) or high (emergency) brake cylinder pressure.  The control piston when functioning as an actuated cut off device can be mechanically coupled with a pressure control device by means of a stop coupling or pneumatic coupling. As a result, the control piston is not able to exert any negative effect on the control precision of the max-imum pressure control device.
