Abstract: Abstract Separation of Oil Fraction from Oil-in-Water Emulsions A method is provided for separating dispersed, fine oil droplets from crude oil produced water which method comprises adding very small amounts of an aluminum  or iron cation emulsion breaker to the dispersion followed by agitation of the dispersion by a rotating paddle stirrer at a paddle tip speed of 0.15 to 0.40 meters per second for 10-30 minutes.          The method provides for a substantial reduction over previous methods in the amount of emulsion breaking chemical used and, as well, reduces the amount of oil retained in the water to levels as low as 0.5 ppm.

Abstract: INVENTOR:  JACQUES MEIER INVENTION: APPARATUS FOR COLLECTING FOLDED PRINTED SHEETS                 ABSTRACT OF THE DISCLOSURE            Along a collecting conveyor serving to take-up the folded printed sheets in a straddling fashion there is arranged a number of infeed members serving to feed the printed sheets.          The infeed members have a delivery region which merges with the collecting conveyor.  To increase the efficiency or output of the apparatus without increasing the conveying velocity of the collecting conveyor and to additionally spare the printed sheets from undergoing a sudden change in their direction of movement during the transition from the infeed members to the collecting conveyor,  each of the  infeed members contain controlled gripper units attached to an endless revolving traction element and serve to grip the fold of the printed sheets.  At least the delivery region of the infeed members extends in the same direction as the conveying direction of the collecting conveyor which,  in turn contains a number of receiving saddles for receiving the printed sheets,  these saddles being arranged at a distance from each other and extending transversely with respect to the conveying direction.

Abstract: ABSTRACT OF THE DISCLOSURE     EXPANSION JOINT     An expansion joint for sealing the channel between two sections of roadway has a plug and a fluid-polymer poured into the joint and allowed to set in situ in the channel.  Enclosed within the fluid is a core of a mastic material which is more plastic and less elastic than the fluid-polymer.  The elasticity of the fluid-polymer allows the joint to accommodate changes in the size of the joint due to e.g. thermal expansion and contraction.  Plastic flow of the core permits changes of shape of the joint to be absorbed without causing excessive stressing of the sides of the channel to which the fluid-polymer adheres.

Abstract: Abstract of the Disclosure Methods and systems for effecting a variety of elec-tronic funds transfer transactions are based upon the use of unit records containing preprinted non-machine readable data, preprinted machine readable data, and manually entered data, and conversion of such records from negotiable instruments to documentary evidence of the satisfactory completion of the transaction.  By first automatically reading the encoded data on the unit record and incorporating transaction data and security information in messages transmitted from a terminal, a financial institution can verify the validity of the trans-action, effect the transaction and return an authorization message containing both reference and transaction information for imprinting on the unit record.  The record then evidences the satisfactory completion of the transaction, and no further document generation or handling are needed at the merchant and financial institutions involved.  The record is capable of usage as a conventional negotiable instrument if terminal facilities are inoperable or not available.

Abstract: ABSTRACT OF THE DISCLOSURE     A universal joint seal is provided for a universal joint, which seal is more effective in retaining lubricant and in pre-venting the ingress of water and contaminants, particularly when engaging surfaces which tend to be rough.  In a specific form, the universal joint includes a cross having a body and trunnions extending therefrom with an annular shoulder and an adjacent surface of circular cross section at the juncture of said body and each of said trunnions.  The bearing cup has an open end which receives the trunnion and can have an annular groove adjacent the open end. The universal joint seal comprises a resilient sealing member having at least two circular lips which engage the annular shoulder of the cross and at least one addi-tional lip which engages the adjacent surface of the cross.  The sealing member also has at least one lip which engages the open end of the cup and additional lips which engage the groove portion of the cup.  Thus, at least three seals are provided between the seal and the cross and between the seal and the cup to contain lubricant in the cup and to prevent the ingress of water and con-taminants.

A diode (30) is connected in series with the fila-ment (6).  This reduces the voltage across the filament and increases the current passing through it, so that shorter and greater diameter filament wire is used.  This makes a stronger filament than is used in a conventional incandescent lamp with no diode, and makes the filament more resistant to displacement by mechanical forces.      _

Abstract: ABSTRACT An inverter, which supplies A.C. power to a motor for driving the cage of an elevator, is feedback-controlled by detecting the A.C. power by means of a detector. The detector provides an output (offset voltage) even when the operation of the inverter is at a stop. The output value fluctuates in accordance with the changes of circumstances such as temperature changes, and the inverter is affected by the fluctuations, so that the inverter generates power with which the motor produces a torque ripple. In order to solve this problem and to perform an operation of reduced torque ripple, the offset voltage of the detector is sensed, and a drive control signal for the inverter is properly changed on the basis of the sensed offset voltage.

Abstract: METHOD AND APPARATUS FOR GENERATING CURSORS     FOR A RASTER GRAPHIC SYSTEM                         A B S T R A C T    Method and apparatus for generating cursors for display by a color raster graphic system.   The cursors displayed can assume any one of a plurality of forms.   Each cursor has predetermined boundaries and includes all pixel positions of the raster within its boundaries.  One pixel position is designated as the origin of the cursor and selected ones of the pixel positions for each form of the cursor will display the CORSOR color and intensity.          The address of the origin of a cursor and its form are designated by the graphic controller of the system. The address of  the origin is compared with the addresses of the pixel produced by the raster scan logic, and, when the same,  the form number and the x and y coordinates, the addresses of the pixel positions of the  cursor  relative  to  the  origin  thereof,  are  produced  and applied  to  a  read-only  memory  which  produces  cursor  control signals stored at the addressed locations of the cursor memory.          The cursor control signals are produced in synchronization with the  scanning of  pixels,  the positions  of which  correspond  to selected pixel positions of the cursor and are applied to the color look-up memory of the system. Such pixel control signals cause the color look-up memory to produce color control signals which cause pixels corresponding to a designated pixel position of the given pixel and form of cursor, to be displayed in the cursor color and intensity.

Abstract: A b s t r a c t The invention relates to a method and a device for reducing the rewetting of a web after a press nip. The web to be dried is passed together with a press felt through a press nip formed by a first and a second press roll. The web and the felt are separated from each other after the press nip. For reducing the compressive pressure as quickly as possible after the center line of the nip, a mat made of a water-impermeable and resilient material is arranged to pass through the nip, said mat being in contact with the surface of either press roll and one of the surfaces of the web. After the press nip, the mat is subjected to a tensile stress, preferably by means of a second pair of rolls for preventing the returning of the mat to its original thickness starting immediately after the center line of the press nip.
