Abstract: ABSTRACT OF THE DISCLOSURE           A bearing bushing for the journal bearings of rail vehicles, is formed of a part-circular segmental bearing mem-ber and arranged in a journal bearing box above an axle, the journal bearing box retaining underneath the axle a lubricating pad which receives lubricant from an oil sump and serves to lubricate a rotating axle journal extending into the journal bearing box.  The bearing bushing comprises a tinned support body having a plurality of dovetail-shaped grooves transverse to the axle journal and a bearing bushing segment of white metal having an external surface cast into the dovetail-shaped grooves and an internal surface bearing on the axle journal, groove-shaped depressions being formed in the internal surface of the bearing bushing segment generally below the dovetail-shaped grooves.  Additional grooves are provided in the inter-nal surface between each two neighboring groove-shaped depres-sions and parallel to the groove-shaped depressions, the ad-ditional grooves having dimensions substantially corresponding to the groove-shaped depressions.  The groove-shaped depres-sions and the additional grooves act to collect lubricant, thereby enhancing formation of a lubricating film between the bearing bushing segment and the axle journal.

Abstract: METHODS AND APPARATUS FOR HEATING METAL PARTS WITH MAGNETICALLY DRIVEN TRAVELLING ELECTRIC ARC            ABSTRACT OF THE DISCLOSURE:  Methods and apparatus for the welding and heat treating of metal parts in which an electric arc extends between a pair of adjacent metal parts or between an electrode and one or more metal parts with the arc tra-versing the metal part or parts a plurality of times during the heating cycle.  For finite length metal parts, i.e. when the surface or surfaces to be heated do not provide closed paths to be followed by the arc, the arc is initiated, caused to follow the surface, extinguished and then reinitiated, or is caused to traverse the surfaces in alternately opposite directions after initiation.  With finite length metal parts, run-off tabs are provided at the ends of the surfaces to prevent overheating at such ends.  A magnetic field causes the arc to traverse the surfaces and may be modified in strength or distribution to vary traverse rate.  Also, by varying the magnetic field path, by superimposing another magnetic field or by gas pressure, the arc may be caused to follow paths which traverse entire surfaces even though arc cross-section is less than the width of surfaces.  The arc may be direct or alternating current and the magnetic field may be constant or variable in both magnitude and polarity.          Sensors responsive to arc position may be used to control reversal of direction of arc movement, arc speed, magnetic field, etc.

Abstract: Abstract of the Disclosure A circuit for interpolating discrete data points or horizontal line segments of a single valued function in one direc-tion into a continuous line display. So that only one value need be produced from a memory for each display position along one axis of an x,y coordinate system display, the circuit generates lines parallel to the other axis which connect the display at ad-jacent positions along the first axis. The circuit receives and displays a line of data; delays the line of data by one clock pulse and displays the delayed line; compares the line and delayed line to determine the ends of data in the line; stores the posi-tion of the ends of data in a shift register; displays the output of the shift register; and returns the output of the shift regis-ter to the input of the shift register for each end position until data is received in a position adjacent the end position.

Title: Shaving apparatus
Inventor: HOEKSTRA ALBERT
IPC: B26B19/42
Filed: 1978-10-31
Granted: 1981-01-27
Abstract: ABSTRACT  :                     The invention relates to a shaving apparatus having a shear plate with hair-entrance aper-tures and a cutting member with cutters, which is drivable relative to the shear plate. The cutters are provided with lead cutters which are movable relative to the cutters, which lead cutters are positioned against the shear plate with a sliding surface in the assembled condition.  As a result of this the lead cutter, which will generally have a substantially smaller thickness than the cutter, may get into the hair entrance aperture with great risk of damage to the apparatus.  In order to eliminate this drawback, the sliding surface of the lead cutter is given such a shape and dimension s that in each position relative to a hair-entrance aperture the sliding surface is in contact with the part of the shear-plate wall which adjoins the hair-entrance aperture.

Abstract: Abstract of the Disclosure This control serves to optimize thrust during steady state and transient operation modes of a turbofan engine of the mixed flow type by adjusting or trimming the exhaust nozzle area as a function of fan pressure ratio and fan rotor speed and by adjusting or trimming the core engine fuel flow as a function of fan rotor speed and/or turbine inlet temperature.  The control serves to enhance stability by assuring airflow in the engine and its inlet is with a given value avoiding inlet buzz and high distortion to the engine and avoiding even transient operation in conditions that might cause compressor flow instability or stall.  Fuel flow is adjusted or trimmed as a function of fan rotor speed or turbine inlet temperature limits depending on which is calling for the least amount of fuel.

Abstract: PROCESS FOR THE SEPARATION OF AMMONIA AND CARBON DIOXIDE FROM MIXTURES CONTAINING   AMMONIA, CARBON DIOXIDE AND WATER              ABSTRACT OF THE DISCLOSURE      An improved process for the separate recovery of substantially pure ammonia and substantially pure carbon dioxide from mixtures containing ammonia and carbon dioxide, and possibly water, such as are obtained as by-products in the manufacture of melamine from urea or the synthesis of urea from ammonia and carbon dioxide.  The by-product mixture is introduced into a process loup having an ammonia separation zone, a car-bon dioxide separation zone and a desorption zone, the zone to which the mixture is initially fed being dependent upon its composition.  The separation is effected by maintaining a system pressure differential between the ammonia and carbon dioxide separation zones, or adding diluting water to the carbon dioxide separation zone.  The efficiency of the separation is enhanced by introducing an ammonia containing gaseous phase into the bottom of the carbon dioxide separation zone.

Abstract: ABSTRACT A device for use in vacuum suction systems for with-drawing fluids from a patient's body cavity, such as the stomach, wherein the device includes a chamber that is located in the flow stream of such fluids between the patient and the source of vacuum.  At predetermined intervals, the device forces a quan-tity of the withdrawn fluid from the chamber, back into the suc-tion tubing leading to the patient such that some of the fluid previously removed from the body cavity is forced backward toward such cavity under a positive pressure to dislodge any ob-structions that may have occurred in the tubing or at the end of such tubing. In the preferred embodiment, the device is effect-ively self-contained and needs no source of positive pressure or electricity for its operation and is readily and fully oper-able from present commercial intermittent suction systems with-out revamping or otherwise modifying existing systems.
