Title: Photoelectric ice accumulation monitor using dual detectors
Inventor: REIN ROBERT G JR
IPC: G08B19/02
Filed: 1988-06-30
Granted: 1990-10-16
Abstract: ABSTRACT      Apparatus and method using internal reflection of electromagnetic radiation to detect ice or water on pavements or other surfaces and to continuously measure the thickness of the accumulation.  A prism which is transparent to pulses of electromagnetic radiation from an emitter is mounted in the pavement with an exposed prism surface flush with, and in the plane of the surface being monitored for the accumulation.          Radiation from an emitter is directed at the exposed prism surface at an angle so that the radiation is totally reflected when the exposed surface is bare, but only partially reflected when there is an accumulation. Radiation detectors are positioned  so that changes in the intensity of internally-reflected radiation are measured and interpreted to detect the onset of an accumulation, measure the thickness of the accumulation, distinguish accumulations of ice from accumulations of water, and distinguish accumulations of mud or dirt from accumulate ions of ice or water.

Granted: 1992-03-03
Abstract: Method of Controlling Fluid Influxes in Hydrocarbon Wells Abstract The invention relates to a method of real time control of fluid influxes into an oil well from an underground formation during drilling.  The injection pressure Pi and return pressure Pr and the flow rate Q of the drilling mud circulating in the well are measured.  From the pressure and flow rate values, the value of the mass of gas Mg in the annulus is determined, and the changes in this value monitored in order to determine either a fresh gas entry into the annulus or a drilling mud loss into the formation being drilled.

Abstract: A METHOD OF PREPARING A PULP  ABSTRACT OF THE DISCLOSURE            A method of preparing a pulp for digestion in a continuous process from a fiber-containing cellulose material is described. It com-prises the following sequential steps: a) preimpregnating said fiber material by mixing it with cooking liquor so as to form a fiber suspension having a fiber concentra-tion of about 5-15 percent by weight, b) impregnating and fluidizing said fiber suspension under a pres-sure above atmospheric pressure by feeding the fiber suspension into a centrifugal pump comprising fluidization means exerting shearing forces on the fiber suspension so as to separate and at least partially disintegrate fiber bundles from each other, c) feeding said fiber suspension to a press by means of said centrifugal pump while continuing said pressure impregnation of the fiber material with cooking liquor from the fiber suspension, d) thickening said fiber suspension by dewatering it in said press while subjecting the fiber suspension to a final impregnation under a pressure above atmospheric pressure so as to form a substantially completely impregnated pulp having a fiber concentration of about 20 to 40, preferably 20 to 30, percent by weight, and e) feeding the resultant pulp into a digester by means of the pressure created mainly or completely by the centrifugal pump.

Title: High rate, bidirectional drive for a bipole stepping motor watch
Inventor: KAMENS BRUCE H
IPC: G04C3/14
Filed: 1989-06-09
Granted: 1992-06-09
Abstract: ABSTRACT In a quartz analog wristwatch it is known to use a bipole stepping motor driven in discrete steps for timekeeping and setting. It is also known to drive the motor in discrete steps at a normal timekeeping rate or at a higher rate for setting the time, however the higher rate is limited by the need for the rotor of the motor to stabilize after each step. In this invention an improved high rate, bidirectional drive circuit for a bipole stepping motor is achieved through the use of drive pulse generation and modulation circuitry and a low impedance drive coil. Stabilization after each step is eliminated and the rotating system rotates at a substantially constant angular velocity during the setting mode.

Title: Method and system for managing an electronic memory representing predetermined homogeneous units
Inventor: HAZARD MICHEL
IPC: G06Q40/00
Filed: 1989-07-18
Granted: 1993-10-12
Abstract: The invention relates to a method for management of an electronic memory representing predetermined homogenous units, of the generic type comprising inscribing in memory a stop indicating the balance at the end of a transaction. In this method, the memory is divided into elements including a non-specific number of cells, and at the time of a transaction, the search for the stop is performed by determining at the outset the element in which it is located, and then the precise position that it occupies in this element. A new stop is then inscribed starting at the position of this previous stop, and then this previous stop is neutralized so that it will be ignored in later transactions. The invention is applicable to electronic payment devices.

Abstract: ABSTRACT OF THE DISCLOSURE    A single tier dryer section apparatus is disclosed for drying a web extending through a paper machine.  The apparatus includes a first dryer and a dryer felt extending around the first dryer such that the web is disposed between the felt and the first dryer for drying the web. A vacuum transfer roll is disposed downstream relative to the first dryer  such that the web and felt extend contiguously from the first dryer to and around the transfer roll so that the felt is disposed between the web and the roll during transit of the web and felt around the roll.  A second dryer is disposed downstream relative to the transfer roll such that the web and the felt extend contiguously from the transfer roll to and around the second dryer so that the web is disposed between the felt and the second dryer during transit of the web and the felt around the second dryer.  The transfer roll includes a perforate shell such that when the roll is connected to a source of partial vacuum, a partial vacuum is generated within the shell for urging the web into close conformity with the felt and towards the perforate shell.  The transfer roll is also movable from a first location to a second location.  The first location is closely adjacent to the dryers so that the partial vacuum urges the web into conformity with the felt for inhibiting fluttering of the web. The second location is farther away from the dryers than the first location so that damage to the first dryer and the roll in the event of the web wrapping around the first dryer is inhibited.

Abstract: A method of cutting panels or stacks of panels comprises the use of only a circular cutting saw to effect extremely neat cuts at rapid rates and with no splintering. The saw will cut a panel in two steps, first by acting thereon through a portion of its thickness during a horizontal stroke, and then through the remaining portion of its thickness during the reverse stroke, while the direction of rotation of the saw remains unchanged and is such that the teeth thereof act successively on the two faces of the panel and press them inwardly of said panel. The saw can be adjusted with precision either horizontally and vertically. Before being positioned for the former of said two working steps, the saw is displaced both vertically and horizontally with precision, to effect in the side of the panel whereon the cutting stroke is initiated and terminated, one or more incisions submitting the material of said panel to inward compression, which helps avoiding the formation of splintering during the subsequent cutting operations.
