Abstract: Elastic substantially linear olefin polymers are disclosed which have processability similar to highly branched low density polyethylene(LDPE), but the strength and toughness of linear low density polyethylene (LLDPE). The polymers have processing indices (PI's) less than or equal to 70 percent of those of a comparative linear olefin polymer and a critical shear rate at onset of surface melt fracture of at least 50 percent greater than the critical shear rate at the onset of surface melt fracture of a traditional linear olefin polymer at about the same I2 and M w M n. The novel polymers can also have from 0.01 to 3 long chain branches/ 1000 carbons along the polymer backbone and have higher low/zero shear viscosity and lower high shear viscosity than comparative linear olefin polymers. The novel polymers can also be characterized as having a melt flow ratio, I10/I2 >= 5.63, a molecular weight distribution, M w/M n defined by the equation: M w/M n <= (I10/I2) - 4.63, and a critical shear stress at onset of gross melt fracture greater than 4 x 10 6 dyne/cm2.

Abstract: A method is described for processing waste materials in the form of filter rods, filter cigarettes and the like comprising filter material with inner hollow volumes accessible from the outside  and  at  least  one  other  material  component,  in particular paper and tobacco, wherein the following process steps are carried out: the waste material is distributed in a liquid in a pressure vessel. By increasing the pressure or decreasing the temperature an inert gas is dissolved in the liquid.  Subsequently the temperature is increased or the pressure deceased so that fine gas bubbles develop within the filter material which permits the latter to float whereby a separation  from  the  further  material  components  to  be separated is possible. With this method a separation of the waste material into its individual component parts is possible so that for example valuable filter material in the form of cellulose acetate is obtained in highly pure form and can be used again for the production of filter materials.

Abstract: When a ring with an exposed dental X-ray film mounted thereon is thrown into a first tank filled with a processing solution, the ring is scooped into a space of a ring-holding portion of a rotating arm through a first opening.  As the ring-holding portion is moving in the tank, the ring is pushed by a tilted bottom portion while being held within the space by a release preventing wall and a door so that the ring is also moving together with the ring-holding portion.  When the ring-holding portion has fully moved out of the tank, the door is opened and the ring is released from the space into an adjacent tank through a second opening.           As the door is kept closed until the ring-holding portion fully moves out of the tank, the automated development processor according to this invention is free of the conventional problem that the ring could fall and sink to a bottom of the tank during its movement through the tank.

Title: Steerable rotary drilling systems
Inventor: BARR JOHN D
IPC: E21B47/18
Filed: 1996-02-23
Granted: 2006-05-09
Abstract: A steerable rotary drilling system has a bottom hole assembly which includes, in addition to the drill bit, a modulated bias unit and a control unit, the bias unit comprising a number of hydraulic actuators around the periphery of the unit, each having a movable thrust member which is hydraulically displaceable outwardly for engagement with the formation of the borehole being drilled. Each actuator may be connected, through a control valve, to a source of drilling fluid under pressure and the operation of the valve is controlled by the control unit so as to modulate the fluid pressure supplied to the actuators as the bias unit rotates. If the control valve is operated in synchronism with rotation of the bias unit the thrust members impart a lateral bias to the bias unit, and hence to the drill bit, to control the direction of drilling. Pulses transmitted through the drilling fluid as a result of operation of the bias unit are detected and interpreted at the surface, or at a different location downhole, to obtain information regarding the operation of the bias unit or other parts of the bottom hole assembly. Data signals from downhole sensors may be arranged to modify the control and operation of the bias unit in such manner that the data is encoded as pulses generated in the drilling fluid by the bias unit.
