Patent CA-2021479-A1 (CA)
Title: Doctor bar
Inventor: HENSELER KLAUS
IPC: D21H23/58
Filed: 1990-07-18
Abstract: ABSTRACT           A doctor bar consists of two different circular disks 1,2 that are clamped or fixed in some other way on a cylindrical carrier bar 3.  Circular disks 2 with a smaller diameter and from elastic material alternate with circular disks that have a larger diameter and are made of a very wear-resistant material, specifically ceramic.  The difference in the outside diameter makes for twice the groove depth of peripheral grooves of the doctor bar that are formed between the various circular disks.

Title: Bearing apparatus and method for preloading bearings for rotary - vibratory drills
Inventor: ROUSSY RAYMOND J
IPC: E21B7/24
Filed: 1990-09-19
Abstract: A vibratory apparatus includes an outer member with a central opening. An inner member is within the opening of the outer member.  There are two sets of bearings between the outer member and the inner member for permitting relative rotation therebetween about an axis. The two sets of bearings are spaced apart along the axis, each having an inner race and an outer race.  The inner races are slidably mounted on the inner member.  A portion of the outer member is disposed between the outer races so as to hold the outer races a first distance apart and so the inner races are held a second distance apart when the inner member and outer member are unloaded.  Each of the sets of bearings transfers from the inner member to the outer member those forces acting along the axis which are directed towards the other set of bearings only.  There is a spacer disposed between the inner races.  A nut connected to the inner member biases the inner races towards each other along the axis with a force which has a first component transmitted from the inner member to the portion of the outer member by the sets of bearings and a second component which is borne by the spacer.

Inventor: BAUMHAUER JOHN C
IPC: H04R3/02
Filed: 1990-10-09
Abstract: A loudspeaking telephone station (speakerphone) includes a loudspeaker and one or more microphones within the same housing. The microphones are directional, each having a polar response characteristic that includes a major lobe, one or more side lobes, and nulls between pairs of lobes. The loudspeaker is positioned in the null of the polar response characteristic that resides between the major lobe and an adjacent side lobe. The microphone apparatus is positioned so that its major lobe is aimed in a direction that is generally perpendicular to the direction that the loudspeaker is aimed. Means are provided for increasing the distance between input sound ports of a first-order-gradient (FOG) microphone and thereby improving its sensitivity. A pair of such improved FOG microphones are used in assembling a second-order-gradient microphone. Full duplex operation is achieved when a pair of echo cancelers are added to further reduce the coupling between the transmit and receive directions of the speakerphone.

Title: Stator coil water system early alert hydrogen leakage monitor
Inventor: SNUTTJER OWEN R
IPC: G08B21/00
Filed: 1990-11-21
Abstract: 55,560 ABSTRACT OF THE DISCLOSURE      An apparatus for monitoring hydrogen leakage from a generator frame into the stator coil water cooling system.  The monitor is designed to alert the operator should leakage exceed a rate of twenty cubic feet per day (20 cfd).  A pressure relief valve set at four (4) psig and orifice are provided, along with a second relief valve having a higher setpoint than the first, such that pressure will increase in the holding tank if leakage exceeds 20 cfd setpoint of the orifice.  A high pressure alarm, set at a level higher than the first relief valve but less than that of the second, will then sound to alert the operator if such a condition exists.  A bypass valve is also added to protect the system from an overly large or gross failure of the system.  by continuously monitoring a relatively small steady state leakage rate, the operator can be aware of a minor problem which can be corrected at a scheduled maintenance outage, before a gross failure of the system, requiring a costly shutdown of the turbine-generator, would otherwise occur.

Title: Method of maintaining an established connection in a mobile radio system comprising both analog and digital radio channels
Inventor: DAHLIN JAN E A S
IPC: H04L25/02
Filed: 1990-03-28
Abstract: The invention relates to a method in a mobile radio system having both digital and analog radio channels. An object of the invention is that a connection established on a digital radio channel often shall be possible to maintain even when the time dispersion on available digital radio channels exceeds the designed maximum time dispersion of equalizers in receiving stations. According the invention equalizers in the receivers of the system may be designed for a smaller maximum time dispersion than the total time dispersion the whole system shall be capable to handle. Instead handover is made to an other channel when the time dispersion of a used digital channel tends to become too big. When an other digital radio channel with low time dispersion is available handover is preferably done to this channel. Alternatively or in the absence of such a digital radio channel handover is performed to an analog radio channel.

Title: Producing a polyethylene terephthalate based polmer from a lower dialkyl ester of a dicarboxylic acid and a glycol
Inventor: ENGEL-BADER MONIKA
IPC: C08G63/82
Filed: 1990-12-14
Abstract: PRODUCING A POLYETHYLENE TEREPHTHALATE BASED POLYMER FROM A LOWER DIALKYL ESTER    OF A DICARBOXYLIC ACID AND A GLYCOL                     ABSTRACT OF THE INVENTION     A process for producing PET based polyester polymers from a lower dialkyl ester of a dicarboxylic acid and a glycol selected from the class of ethylene glycol, diethylene glycol, polyethylene glycol, blends of ethylene glycol and propane and/or butane diol, or mixtures of two or more of these, using the novel catalyst system and a small amount of dicarboxylic acid is described.  The novel catalyst composition includes from about 10 ppm to about 150 ppm manganese; from about 50 ppm to about 250 ppm lithium; preferably from about 10 ppm to about 40 ppm cobalt; and from about 200 ppm to about 400 ppm antimony, all amounts being based upon the expected yield of the polyester based polymer.  The process for using the novel catalyst composition to make polyester includes the step of employing an effective catalytic amount of manganese and lithium in an ester interchange reaction where the lower dialkyl ester and glycol produce monomer; and using an effective catalytic amount of cobalt and antimony in the polycondensation reaction and a small effective amount of dicarboxylic acid to convert the monomer to polyester.  Using the novel catalyst composition and effective amount of dicarboxylic acid to produce a polyester based polymer drastically increases both the ester interchange rate and the polymerization rate, such that the ester interchange time and the polycondensation time are drastically reduced as compared to more conventional systems for producing polyester.
