Title: Method of creating a registered pattern on a metal coil and associated apparatus
Inventor: LAMANTIA PHILIP J
IPC: B65H23/188
Filed: 1991-03-05
Granted: 1995-09-26
Abstract: A method for creating a registered pattern on a metal coil includes providing a pattern applicator roll and a drive motor for rotating the roll, moving the coil into contact with the applicator roll to permit it to create a pattern sequentially on the moving strip from the coil, measuring the pattern length and comparing the same with the desired pattern length, and adjusting the speed of rotation of the pattern applicator roll if the measured pattern length departs from the desired pattern length by a predetermined amount.  Preferably, coil line speed is also monitored.  A microprocessor may be used to effect the comparison between the desired pattern length and the actual pattern length.      Apparatus for creating a registered pattern on a metal coil includes a pattern applicator roll which has the strip from the coil moved into contacting relationship therewith, an appropriate drive motor to drive the roll, and apparatus for monitoring coil line speed, pattern length and motor speed.  A microprocessor stores the desired pattern length and receives information regarding line speed, pattern length, and motor speed, and where an adjustment is desired, either speeds up the applicator roll where the pattern length is longer than the desired pattern length, or reduces the applicator roll speed, if the pattern length is less than the desired pattern length.

Abstract: In an optical recording medium on which the main information is recorded on a pre-formed recording track along the track direction and in which the recorded data are read out by optical means, frame sync signals based on the same format as the format for the main information are pre-recorded by offsetting the recording track itself along its width for each frame as an information recording unit, for facilitating frame synchronization and simplifying the construction through the of a sole common synchronizing circuit. The information pre-recorded by offsetting the track itself along its width includes not only the frame sync signals but also any reproduce-only information for increasing the disc recording capacity. The reproducing circuit for reproducing the frame sync signals of the main information recorded along the track direction of the recording track, and the reproducing circuit for reproducing the frame sync signals having the same format as the main information among the information recorded by offsetting the track along its width, are formed as a common circuit for simplifying the circuit construction.

Granted: 1999-01-12
Abstract: A filter device with a filter container (1) closed on all sides, into the bottom of which a cartridge-shaped filter insert (2) has been inserted, under which a filtrate catch reservoir (6) is disposed.  An air supply tube (40) is inserted into the filter container (1), which terminates on the inside in an air compensation hole (3) at an adjustable height (A) above the inlet of the filter insert (2), so that the corresponding hydrostatic pressure of the liquid (F) determines the flow-through speed of the filtrate.  The air supply tube (40) terminates at the bottom above the filtrate outlet of the filter insert (2), so that a filtrate build-up terminates on the corresponding level (MN) and the filter insert (2) is closed airtight in this way.

Title: Automatic drilling system
Inventor: BOWDEN BOBBIE JOE
IPC: E21B44/02
Filed: 1993-04-19
Granted: 1999-08-24
Abstract: An automatic drilling system regulates the drill string of a drilling rig in response to any one of, any combination of, or all of drilling fluid pressure, bit weight, drill string torque, and drill string RPM to achieve an optimal rate of bit penetration. The automatic drilling system includes a drilling fluid pressure sensor, a bit weight sensor, a drill string torque sensor, and a drill string RPM sensor which deliver a drilling fluid pressure signal, a bit weight signal, a drill string torque signal, and a drill string RPM signal to a drilling fluid pressure regulator, a bit weight regulator, a drill string torque regulator, and a drill string RPM regulator. The regulators control a drill string controller in response to the above signals so that it manipulates the drilling rig to release the drill string at a rate which maintains the maximum rate of bit penetration.

Granted: 2003-06-10
Abstract: The invention is directed to the sorting of particles according to the thermal properties of the particles. The method comprises, as a first step, subjecting the particles to one ox more thermal treatment steps so that particles with different intrinsic thermal properties are brought to different temperatures. In the next step, conducted either during or after the thermal treatment steps, the particles are subjected to a further, non-thermal treatment. This treatment is chosen to give selected particles that are distinguished from other particles by a difference in temperature a certain feature which is not an intrinsic feature of the particles prior to the thermal treatment step. The particles can then be sorted into a fraction having the certain feature after a predetermined time period has elapsed since the further treatment step and a fraction not having the certain feature after that time lapse.

Abstract: A passive exercise unit for manipulating legs and/or arms of a patient to achieve improved circulation, development of muscles and achieve full extension of otherwise crippled limbs.  A motor-driven crankshaft member carries leg cradles on opposite sides of a housing that is supported on a base.  This base can be, if desired, releasable fastened to a bed supporting the patient.  These cradles are pivotally supported, and their position relative to the crankshaft permits a selected degree of motion for the patient's legs.  An upwardly-extending frame carries arm exercising components that include cables to hand grips. Motion for these cables is achieved by connections to the crankshaft used for the leg cradles.  This frame can be folded against, or stored in, the housing when not in use.  In a preferred embodiment there are glove units to assist in the holding of hand grips by the patient.

Granted: 1999-12-28
Abstract: A method and an apparatus for determining the interfacial or surface tension, static or dynamic conditions, between two liquids or between a gas and a liquid under conditions of varying temperature and pressure; and a method for adjusting the interfacial or surface tension in a petroleum reservoir for enhanced oil recovery. A tensiometer is provided which is capable of measuring interfacial or surface tension under pressure and temperature conditions which simulate those present in an actual petroleum reservoir. Measuring the interfacial and surface tension values under actual reservoir conditions then enables the selection of surfactants and other materials for adjusting the interfacial and surface tension to desired values for optimizing the enhanced oil recovery from that reservoir. A tensiometer is provided which includes a calibration body which is imaged along with the image of the test droplet in the tensiometer chamber.   This imaging of both the calibration body and the test droplet provides the capability of correction of distortions in the image due to the nature of the chamber window for high pressure and/or high temperature measurements. The tensiometer is also provided with a surface against which the test droplet is imaged and measured, which is an annealed ionomer polymer coating on a polymer surface.

Abstract: A method and system for parametrically generating characters and fonts. A font generation system (10) allows a user to create a Terafont binary file (34). The user can create a new font, or replicate an existing font. The parametric data are distributed as files or embedded in documents.

The parametric data provided to the font engine at least include a minimal set of font measurement data, such as a PANOSE .TM. number, which are used to compute global variables representing typographic characteristics common to many-if not all-of the glyphs in the font. Additional global and local variables needed to capture nuances of individual characters are computed or assigned default values by the font engine (30).
