Title: Downhole tool
Inventor: INNES FRANK A S
IPC: E21B47/18
Filed: 1993-10-14
Abstract: A downhole tool (100) for generating pressure pulses in a drilling fluid comprising an elongate body (107, 127) and a plurality of blades (116) spaced around the body.      The blades are each divided into an independent front section (116a) and rear section (116b), forming a set of front sections and a set of rear sections, at least one of the set of front sections and the set of rear sections being mounted for rotation and being angularly displaceable relative to each other between a first position in which the sections are aligned and a second position in which the rear sections obstruct fluid flow between the front sections to generate a pressure pulse. The tool includes a first set of driving blades in front of the blades (116) for generating a torque on the blade sections, the driving blades being curved in a first direction, and an escapement means (129) which is radially movable to permit stepwise rotation of the blade sections, and thus to move the blade sections between the first and second positions. The tool additionally comprises a set of stator blades (162) positioned in front of the set of front sections. The stator blades are curved in a second direction opposite to the first direction.

Title: Vertical accumulator/stacker
Inventor: ELLIS ROBERT A
IPC: B41L43/16
Filed: 1993-10-21
Abstract: ABSTRACT OF THE DISCLOSURE     An accumulator for business forms is easily inserted into, or removed from, a path of continuous format, zig-zag business forms being fed from one business form handling machine (such as a folder) to another (such as a mailing machine like an inserter).  A barrier having drive belts on one face is movable from a position allowing forms to pass under it, to a barrier position in which the forms engage the barrier and are slowly driven up the barrier until they bend over by their own weight onto a shelf.  The forms are also driven along a shelf into contact with a stop, and a stack of forms is formed on the shelf.  By handling the forms in this way the forms are creased along the perforations between the continuous forms (making subsequent separation easier) and prevented from developing a curl.

Title: Cycloolefin polymer molding composition of improved stability to chemical degradation
Inventor: EPPLE ULRICH
IPC: C08K5/5377
Filed: 1993-11-26
Abstract: Abstract Cycloolefin  polymer  molding  composition of  improved stability to chemical degradation.            A cycloolefin polymer molding composition which comprises organophosphorus compounds of the formula IX                   R13-[P(OR14)2]u   (IX) of the formula X                    (X) or of the formula XI                               (XI) if appropriate in addition to other additives, shows an improved  stability  to  chemical  degradation.     The organophosphorus  compounds  used  according  to  the invention maintain the melt viscosity of the molding composition at the highest level (very small deviation from the starting value). They furthermore lead to the best initial colors of test specimens and to a relatively low change in color after kneading experiments.
Patent CA-2111119-A1 (CA)
Title: Solution pumping system with compressible pump cassette
Inventor: WECKER SHELDON M
IPC: F04B43/02
Filed: 1991-12-27
Abstract: A solution pumping system includes a compressible pump cassette (14) having front (16) and rear (18) body members, and an elastomeric diaphragm (20) positioned therebetween. The front and rear body members are joined to each other for limited, relative movement, which movement effects compression of diaphragm. The pump cassette is removably positionable in a pump driver of the system, which can be configured to effect compression of the cassette for use. In this way, the desired compression of the diaphragm during use can be achieved, while avoiding problems associated with compression set or load decay during storage of the cassette prior to use.

Abstract: PAPER SHEETS WITH PRESSURE SENSITIVE ADHESIVE FORMING AN EASEL PAD                      ABSTRACT      Discrete overlying sheets form a pad or chart with the sheets secured one to another along an upper margin. Strips of repositional adhesive are coated along the back side of each sheet adjacent the upper margin between weak and strong lines of perforations.  The top sheet may be removed from the pad or chart by tearing along the weak line of perforations and adhered to a support surface using the repositional adhesive.  The sheet may subsequently be removed from the support surface by tearing along the strong line of perforations.  The ends of the lines of adhesive may be formed in various patterns to provide additional coated areas or additional uncoated areas.
Patent CA-2116178-A1 (CA)
Title: Speaker System
Inventor: TAKAYAMA SATOSHI
IPC: H04R1/28
Filed: 1994-02-22
Abstract: A speaker system comprises an acoustic tube with one end coupled to the back side of the speaker unit and the other end released to a sound field space through an opening window, and at least one air chamber disposed along the acoustic tube. The cross sectional area of the air chamber is larger than the cross sectional area of the acoustic tube, and the cross sectional area of the opening window is smaller than the cross sectional area of the acoustic tube. Therefore, the air chamber forms an acoustic filter so that the higher resonance frequency components in medium and high frequency region caused in the acoustic tube may not be radiated from the opening window, and formation of peaks arid bottoms of frequency characteristic due to interference with the sound radiated from the front side of the speaker is prevented.      The opening window of a small cross sectional area lowers the resonance frequency of the acoustic tube.      Alternatively, the speaker system comprises an acoustic tube with one end coupled to the back side of the speaker unit and the other end released to a sound field space through an opening window, and at least one air chamber disposed along the acoustic tube. The cross sectional area of the air chamber is larger than the cross sectional area of the acoustic tube, and the cross sectional area of the opening window is smaller than the cross sectional area of the acoustic tube. The branch chamber possessing different route lengths causes a phase difference in the acoustic tube to cancel the resonance in the acoustic tube, so that formation of peaks and bottoms in the frequency characteristic may be prevented.      An acoustic tube with one end closed and other end coupled to the front side of the speaker, suppresses the amplitude of the diagram of the speaker under low frequency region and the generation of abnormal sound such as speaker bottom beat phenomenon.

Title: Method and apparatus for calibrating a gas detector sensor
Inventor: HUNG PATRICK
IPC: G01N27/12
Filed: 1994-10-28
Abstract: An improved method and apparatus for calibrating a gas sensor which exhibits a change in electrical characteristics in response to exposure to a gas. The apparatus comprises a resistor array and a chart. The chart comprises a list of predetermined resistor combinations corresponding to a range of output levels for the sensor. The resistor array is coupled to the output of the sensor. When exposed to a gas, the sensor exhibits a change in conductivity producing an output which generates an output signal with the resistor array. The level of the output signal is measured. The measured level is then compared to predetermined values on the chart which also lists the appropriate resistor combination for each value or range of values. The resistor combination is then set as indicated by the chart.
