Abstract: ABSTRACT A shade assembly for a skylight of the type adapted to be mounted in an opening in a roof structure and including a supporting base mounted in the opening in the roof structure and a dome assembly positioned in the supporting base to overlie the opening.  The shade assembly includes a support bracket adapted to be affixed to the skylight and a shade support having a shade rolled thereabout.  The shade support is rotatably mounted on the support bracket in a manner that permits the shade support to rotate so that the shade can be rolled and unrolled.  A shade actuator is attached to the shade and is adapted to be grasped and activated to actuate rolling and unrolling of the shade.  Guide surfaces are mountable on the skylight in position to engage and guide the actuator out of alignment with the visual passageway through the opening in the roof and the skylight while facilitating the uniform rolling and unrolling of the shade.  An anchor cleat is provided to retain the shade in the unrolled condition, store the shade cord, and provide a safety catch to prevent the shade from re-rolling too fast.

Abstract: "Process and device for the swivelling of a flexible printing plate on the plate cylinder of a printing press"                      A B S T R A C T          A process and a device for register correction by the swivelling of a flexible printing plate on the plate cylinder of a printing press are proposed, in which the printing plate is disposed on the plate cylinder such as to be swivellable about a plate centre of rotation, apparatuses being provided in the press for adjustments to the circumferential and side registers.  The process is characterized in that a final register correction to the printed image by turning the plate after one specimen print is effected such that, first of all, the data of the register deviation of a defined register point are established in circumferential and/or side and/or angular position.  Subsequently, the necessary adjusting operations for the turning of the plate as well as for the correction of the circumferential and side registers are initiated, the adjusting commands -in addition to the previously established data - taking account also of the position of the plate centre of rotation of the associated device.

Abstract: ABSTRACT OF THE DISCLOSURE       A  golf  cart  system  which  can  be  installed  on  the fairway of  a  golf  course  and which  is  excellent  in power economy  and  anti-rolling  and  anti-pitching  motions  of  the cart.   The golf cart system includes a track embedded in the ground and a cart adapted to run on the track.  According to the golf cart system, since the track exposed at the ground is very  narrow,  there  is  less  chance  of  a  golf  ball  hitting against  the  track.   Even  if a golf  ball  should happen  to accidentally  hit  the  exposed  track  portion,  the  ball  will bound  similarly  as  when  striking  on  natural  grass  if  the exposed track portion is covered by elastic members such as artificial turf.   This makes it possible to install the golf cart system on the fairway of a golf course.   In addition, the rolling motion of the cart is effectively prevented by the first  and  second  anti-rolling  rollers.    Especially,  the provision  of  the  second  anti-rolling  rollers  enables  to effectively prevent the rolling motion of the cart, since they are positioned most away from the center of gravity of the cart  and  can  generate  a  large  anti-rolling  moment.    The pitching motion of the cart is also effectively prevented by the anti-pitching rollers.   Thus the provision of the anti-pitching rollers makes it possible to install the golf cart system in a golf course abundant in ups and downs.

Abstract: ABSTRACT         A process for producing a semi-interpenetrating polymer network of polytetrafluoroethylene and silicone elastomers is described which comprises the steps of (1) intimately blending a mixture of a major amount of unsintered and unfibrillated parti-culate polytetrafluoroethylene dispersion resin and minor amounts of (A) a hydrocarbon liquid and (B) an addition curable silicone composition consisting essentially of a polydiorganosiloxane having alkenyl unsaturation,  an organohydrogenpolysiloxane cross-linking agent  a catalyst for promoting crosslinking of said polysiloxane,  and an inhibitor for the catalytic reaction; (2) forming said blend into an extrudable shape; (3) biaxially extru-ding said blend through a die into a shaped extrudate product having a randomly fibrillated structure; (4) evaporating said hydrocarbon liquid, and activating said catalyst so as to generate a cured silicone elastomer and polytetrafluoroethylene semi-inter-penetrating polymer network comprising said fibrillated extrudate structure.  Products produced by this process have improved physi-cal properties as compared to extruded fibrillated polytetra-fluoroethylene dispersion resin alone.

Abstract: ABSTRACT      Extended delignification of kraft pulp in a pressure diffuser allows a pulp mill with a digester (e.g. continuous digester) to increase its production capacity without building a new line, or to decrease its demand in its bleach plant, or to increase the strength of softwood pulp it produces.  Comminuted cellulosic fibrous material is kraft cooked to produce kraft pulp having a blow temperature over about 300°F.  The pulp is diffusion treated in the first stage of a pressure diffuser to replace the water around the pulp with delignifying liquor.  The liquor has a dissolved lignin concentration of less than 12% (optimally less than about 4%), has an effective alkali concentration of at least 2 gm/l (preferably 8-55 gm/l), and a temperature of at least about 300°F.  Treating the pulp with the delignifying liquor significantly reduces the K-number (e.g. on the order of about 5).  After extended delignification, the pulp is washed in subsequent stages of the pressure diffuser.  The components of the delignifying area of the pressure diffuser are of stainless steel to avoid corrosion from the alkaline liquor.

Granted: 1994-03-01
Abstract: ABSTRACT OF THE DISCLOSURE:           Disclosed is a waste water and sewage treatment system for use in an aeration-sedimentation basin or lagoon. The system comprises a summerged water pump mounted in a well in water communication with the basin.  This pump supplies water under pressure to a water header on which a plurality of water jets are mounted in such a manner as to create the forced water circulation inside the basin.  Each water jet incorporates an air-sucking venturi to oxygenate the waste water or sewage.  Valves are provided in the well for disconnecting the water pump from the water header and then connecting it to a sludge collecting duct extending from the well over a given distance into the basin in such a manner as to drain off the accumulated sludge at the bottom of the basin through the sludge collecting duct and drain-out through a sludge disposal pipe.   The system is particularly interesting in that it makes use of the same pump to aerate the waste water or sewage and drain-off the accumulated sludge.

Title: Integrated poly-phase power meter
Inventor: LEYDIER ROBERT A
IPC: G01R21/06
Filed: 1988-06-24
Granted: 1992-05-19
Abstract: INTEGRATED POLY-PHASE POWER METER    ABSTRACT OF THE DISCLOSURE A high accuracy power meter capable of measuring power supplied or consumed in multiple phases of a distribution system is fabricated as an integrated circuit. Voltage and current sensing transducers coupled to the power meter provide input signals having a potential proportional to the voltage and current in the distribution system.  A low charge injection pulse width amplitude multiplier using a digitally-synthesized triangular wave is provided for each phase.  Each multiplier receives the input signals and provides an output signal having a current proportional to the product of voltage and current in that phase of the distribution system.          Charge from the multiplier output currents for all phases is accumulated in a capacitor connected across an autozeroing amplifier, which corrects for its own offset voltage.  The amplifier output controls a switch connected between a reference potential and the capacitor.  When the switch is closed, a reference current is supplied to the accumulating capacitor to balance the charge from the multiplier for each phase.  The frequency of the switch control signal provides a highly accurate measure of the power consumed or supplied by the distribution system.
