Title: Use of polyalphaolefin in downhole drilling
Inventor: FAULK MICHAEL B
IPC: E21B43/11
Filed: 1989-01-12
Granted: 1993-06-01
Abstract: ABSTRACT      The composition of matter and application thereof in the present  invention relates  to  the  application of  a synthetic hydrocarbon compound, a polyalphaolefin liquid, blended in various concentrations with chemical oil and water  emulsifiers,  thinners  and  oil  and water  surface tension  reducers,  the  concentration  of  polyalphaolefin liquid to that of the remaining portion of the blend being no less than 5%; blending the polyalphaolefin liquid and the emulsifiers in a blending tank containing water base drilling mud;  circulating  the  blend of polyalphaolefin liquid and emulsifier with the water base drilling mud down hole,  so that the blend of polyalphaolefin liquid emulsifier  and water  base  drilling mud  lubricates  the drill string or reduces the differential pressure between the wall of the borehole and the drill string so that the drill  string  is  free  to  rotate and  drilling  may be undertaken  with  less  drag  or  torque.   In  another application,   the polyalphaolefin   blended  with   the emulsifier serves as a spotting fluid in order to unstick drill pipe that has become stuck.   In this method,  the polyalphaolefin  is  blended  with  the  emulsifiers;  the polyalphaolefin emulsifier blend is introduced into the borehole as a "pill"; the pill is circulated downhole in the mud system through the annulus to the depth at which the pipe is stuck;  the polyalphaolefin emulsifier blend acts on the differential forces between the wall mud cake and the pipe to reduce the differential pressure between the pipe and the formation, so that the pipe is freed and drilling is able to resume.

Title: Process for preparing a bituminous binder modified with synthetics for construction materials
Inventor: STROMMER ERICH
IPC: E01C7/26
Filed: 1989-06-27
Granted: 1998-07-07
Abstract: Process for the production of a bituminous binder modified with synthetic thermoplastic material for building materials, especially road building materials. In this process for the formation of the binder, molten bitumen together with a thermoplast or a thermoplast mixture, preferably an olefin polymer, is subjected to a homogenization treatment. To the mix containing the bitumen and a thermoplast or a thermoplast mixture, there is fed in the form of kinetic energy an amount of energy corresponding to at least the difference between the treatment temperature and the disintegration temperature of the thermoplast or thermoplast mixture and said mix is braked abruptly on an impakt surface. So readily reacting molecule fragments of the thermoplast or thermoplast mixture are formed which enter into a reaction with the bitumen. Preferably, the mix containing bitumen and the thermoplast or a thermoplast mixture is driven through a narrow gap between two mixing tools standing opposite to one another and rotating relatively to one another.

Title: Cross-flow spray assembly
Inventor: WHITFORD DARRYL R
IPC: B05B15/04
Filed: 1989-06-29
Granted: 1995-03-28
Abstract: A cross-flow spraying method comprising creating an air stream by a fan, spraying a crop with a spray liquid injected into the air stream and passing the spray airborne by the air stream across the crop, receiving some at least of airborne overspray in a suction hood located at the lee side of the crop and recirculating the spray liquid. The air outlet from the suction hood may be redirected to the inlet side of the fan, or the suction hood may have its own exhaust fan, and surfaces which precipitate the spray liquid. By utilising suction as well as pressure, the leaves of vegetation flutter and become more fully covered with the spray liquid. Loss of liquid due to overspray is reduced.

Title: Device for generating an optical collimating beam
Inventor: STANA HANS
IPC: G01B11/27
Filed: 1989-08-31
Granted: 1992-07-07
Abstract: Abstract of the Disclosure The invention is directed to a device for generating an optical collimating beam having a defined angle with respect to a base when mounted thereon even in the presence of extreme mechanical and thermal loads.  The device can be used for testing long guideways on machine tools, for example.  The device includes a housing wherein a collimator is mounted in a form-tight manner for imaging a collimating mark out to infinity.  The collimator is configured as a mirror system and includes several components connected tightly to each other.          These components define a chamber filled with a gaseous medium and through which the imaging beam path extends.  The collimator functions without problems even in the presence of extreme mechanical and thermal loads and, most importantly, is insensitive to temperature changes.

Abstract: A machine for feeding a collapsed beverage can carrier sleeve to a flight bar conveyor and introducing the sleeve in fully open condition to the pocket of the conveyor. After leaving the feed rolls the collapsed carrier sleeve is moved through a fixed guide by lugs on a movable chain. The end flaps on the upwardly facing side panel are held in place on the guide while the end flaps on the downwardly facing side panel are moved downwardly by a fixed cam surface. The substantially opened sleeve is then either given a final kick by rotating arms or is propelled by the feed lugs to accelerate it into the pocket while at the same time fully straightening and opening the sleeve. The carton dimension corresponding to the length of the pocket is the same as the length of the pocket, resulting in more pockets per conveyor length and permitting operation at slower conveyor speeds.
