Title: Process for the production of a liquid crystalline extended chain polymer composition
Inventor: SYBERT JOANNE R
IPC: C08G73/06
Filed: 1987-08-05
Granted: 1995-05-30
Abstract: Novel liquid crystalline extended chain polymer compositions comprising a high concentration of one or more extended chain homopolymers, copolymers or block polymers and certain strong acids are prepared by admixing a high concentration of one or more selected monomers with or without oxidation protecting moieties and one or more of a substantially non-oxidizing strong acid(s) containing P2O5.  Such compositions, which are prepared by polymerization in a reaction vessel maximizing surface-to-volume ratio , are capable of exhibiting high cohesive strength, and are especially suited to the production of high molecular weight ordered polymer fibers.  Fibers, films and other articles formed from these liquid crystalline compositions exhibit exceptionally high physical and heat resistant properties.

Title: Pressure transducer
Inventor: FRIEDRICH JAROMIR
IPC: G01L9/00
Filed: 1988-04-06
Granted: 1993-07-06
Abstract: ABSTRACT OF THE DISCLOSURE     A pressure transducer is provided, in a preferred embodiment, with a pair of diaphragms (29, 28), each with a strain gauge, and with a rubber-like intermediate layer (33) therebetween.  The layer (33) supports the first diaphragm (29) without interfering with its flexing up to a point where the layer (33) becomes non-resilient and transmits further flexing of the first diaphragm to the second diaphragm(28).  The diameter of each diaphragm has to be about 2.75 - 3.75 times greater than that of its central flexing portion forming the bottom of a cavity (30) which, in the shown embodiment, is conical.  The overall thickness of the diaphragm is preferably about 5 times greater than the thickness of the flexing portion to eliminate or at least substantially reduce the influence of parasitic stresses introduced by clamping forces holding the diaphragm in place.  This, in turn, will improve the accuracy of the transduced values which will stay generally linear as long as the deflection of the flexing portion is within about 25% of the thickness thereof.  The invention presents the advance of simple structure affording a wide measuring range and an improved accuracy of measurement.

Title: Round baler having anti-plugging means
Inventor: WHITE BRUCE L
IPC: A01F15/07
Filed: 1988-04-18
Granted: 1992-10-27
Abstract: ROUND BALER HAVING ANTI-PLUGGING MEANS            Abstract of the Invention The baler has an internal chamber within which crap materials are coiled up into a cylindri-cal bale by fore-and-aft spaced-apart,  oppositely moving web stretches, the forwardmost stretch of which is looped around a forward drive roll.  A special bale supporting roller adjacent the bottom of  the chamber keeps the bale from riding against the web wrapped around the forward roll.  The sup-port roll includes a cylindrical shaft and a plural-ity of resilient flaps extending tangentially out-ward from the periphery of the shaft.  During baler operation, crop material tends to be carried down-wardly  by  the  forwardmost  stretch  into  a  zone located between the forward roll and the support roller, but is immediately ejected from the zone by the roller flaps and into the baling chamber, there-by preventing crop materials from wedging between the forward roll and the support roller.  When the flaps are brought into contact with the bale,  they yield to its weight, conforming to the periphery of the shaft,  thereby forming a relatively smooth, circular roller surface for supporting the bale without tearing up the exterior thereof.

Title: Roll coupled vehicle stabilizer system

IPC: B62D53/00
Filed: 1988-06-10
Granted: 1990-10-23
Abstract: ROLL COUPLED VEHICLE STABILIZER SYSTEM          ABSTRACT  Following trailers such as pup trailers have a tendency to whip and/or roll relative to the lead trailer, particularly during evasive manoeuvres such as rapid lane  changing  or  travelling  too  fast  around  a curve.   This invention transfers this tendency to the lead trailer by the provision of a stabilizing assembly between the two.   It consists of a V-shaped connection with a combination vertical and horizontal pivot assembly between the assembly and the following trailer with the frame diverging outwardly and forwardly towards the lead trailer and connecting thereto by means of horizontal pivots.  This assembly is situated above the conventional hitch which normally has a horizontal and vertical pivot at the connection to the lead trailer with the frame diverging  outwardly  and rearwardly  to  the  following trailer to which it is attached by means of a pair of horizontal pivots.   The stabilizer assembly includes a central tube between the diverging frame members with the hitch  attached  to  the  pup  trailer  being  on  a  beam slideable  lengthwise within the  tube in a telescopic manner to allow pivotal action between the two trailers and to maintain the correct geometry during the steering or turning action.

Title: Etch back detection
Inventor: RILEY PAUL E
IPC: H01L21/3065
Filed: 1988-08-12
Granted: 1991-07-23
Abstract: ETCH BACK DETECTION Abstract of the Disclosure An improved method for the etch-back planarization of interlevel dielectric layers provides for cessation of the etch-back upon exposure of an indicator layer.  The indicator layer, usually a metal, metal nitride, or silicon nitride is formed either within the dielectric or over an underlying metallization layer prior to patterning by conventional photolithographic techniques.  A sacrificial layer, typically an organic photoresist, is then formed over the dielectric layer.  Because of the presence of both relatively narrow and relatively broad features in the metallization, the thickness of the sacrificial layer will vary over features having different widths.  As etch back planarization proceeds, the indicator layer which is first encountered releases detectable species into the planarization reactor.  Detection of these species indicates that removal of the overlying dielectric layers to a predetermined depth is achieved. By placing the detectable layer over only those regions which are expected to be exposed last, the method can be utilized to indicate the end point of etch back planarization of the interlevel dielectric.

Abstract: ABSTRACT A process for preparing 15-oxygenated sterols, such as 3.beta.-hydroxy-5.alpha.-cholest-8(14)-ene-15 one, comprising coverting 7-dehydrocholesterol to 3.beta.-benzoyloxycholesta-5,7-diene, converting the 3.beta.-benzoyloxycholesta-5,7-diene to a 3.beta.-benzoyloxy-5-cholesta-7,14-dience, converting the 3.beta.-benzoyloxy-5-cholesta-7,14-diene to a 3.beta.-benzoyloxy-14.alpha.,15.alpha.-epoxy-5-cholest-7-ene and converting the 3.beta.-benzoyloxy-14.alpha.,15.alpha.-epoxy-5-cholest-7-ene to a 15-oxygenated sterol.  Preferably, the 3.beta.-benzoyloxy-cholesta-5,7-diene is converted to a 3.beta.-benzoyloxy-5-cholesta-7,14-diene by (i) contacting 3.beta.-benzoyloxy-cholesta-5,7-diene, in a solvent at a temperature of at most about -55°C, with HCl at a concentration of at least about 2.0 M for a time sufficient to convert the 3.beta.-benzoyl-oxycholesta-5,7-diene to a 3.beta.-benzoyloxy-5-cholesta-7,14-diene; (ii) neutralizing the resultant reaction mixture with a base to prevent formation of a significant amount of 3.beta.-benzoyloxy-5-cholesta-8,14-diene; and (iii) recovering the 3.beta.-benzoyloxy-5-cholesta-7,14-diene.  The 15-oxygenated sterols are useful for inhibiting the biosynthesis of mevalonic acid, which in turn results in the reduction of serum cholesterol levels in animals, amongst other effects.

Inventor: MILLER LUITPOLD
IPC: B60L3/00
Filed: 1989-03-09
Granted: 1994-12-27
Abstract: The invention concerns a method and an apparatus for the automatic control of a guided vehicle and proposes a new safety concept which, if breakdowns and/or emergencies arise, prevents the vehicle from being stopped in tunnels, on bridges or on pathless terrain.  The invention lies in that between preselected stopping regions provided with means for evacuation of passengers and for intervention by rescue services, the vehicle is always operated at such a high speed that even if the driving force fails, travel can still continue from every point of the line on account of its instantaneous momentum at least as far as a preselected subsequent slopping region in the direction of travel, and if a breakdown and/or emergency situation arises the vehicle is brought to a standstill by initiation of automatic train stop or target automatic train stop in this preselected stopping region.
