IPC: C10G5/04
Filed: 1990-07-13
Abstract: The gas mixture to be treated (1) is washed (5) between 0 DEG C and -45 DEG C by means of a solvent (6) for CO2 and C3 and higher hydrocarbons to produce a methane stream (8) containing not more than 2 mol% of CO2 and a CO2-rich liquid phase (11) containing at least 80 mol% of C3 and higher hydrocarbons from the gas mixture (1). The liquid phase (11) is subjected to a demethanization (12, 17) producing a demethanized rich solvent (27) and a methane-rich gas phase (22), and then the rich solvent (27) is subjected to a regeneration producing a regenerated solvent (34) which is recycled into the washing zone (5), and a gas mixture (42) containing the CO2 and the C2 and higher hydrocarbons which are present in the methanized rich solvent, the said gas mixture being separated by regenerative washing with a C5 and higher hydrocarbon solvent, into a CO2-rich acidic gas stream containing, expressed as methane equivalent, less than 10 mol% of hydrocarbons, and into a C2 and higher hydrocarbon cut (48) containing at least 80 mol% of the C3 and higher hydrocarbons present in the gas to be treated (1).

Inventor: SCHIEFER ERWIN
IPC: F16B1/00
Filed: 1992-05-15
Abstract: On the contact surfaces formed by the inner contour of the expanding sleeve (7) and the outer contour of the expansion of the shank (2), an expanding dowel has a friction-reducing coating (10). Said coating (10) produces a friction level between the expanding sleeve (7) and the expansion (3) of the shank (2) which is less than the friction level between the expanding sleeve (7) and the wall of the drilled hole. The friction difference thus produced causes a reliable subsequent expansion behaviour of the expanding dowel in the cracked tension zone. In addition to the coating (10), projections (11, 12) are arranged on the outside of the expanding sleeve (7), which projections (11, 12) are located one behind the other and maintain the contact with the wall of the drilled hole in the event of relatively large displacements of the expanding dowel, primarily in the cracked tension zone.

Title: System for monitoring roll density
Inventor: BAUM SCOTT A
IPC: B65H18/10
Filed: 1990-04-09
Granted: 1993-10-05
Abstract: ABSTRACT OF THE DISCLOSURE     Separate density profiles are obtained for each station of a multi-station winder. The technique requires a single processor for simultaneously monitoring the density of any number of rolls being wound.  The density may also be monitored for the unwind roll for determination of roll structuring changes by a winder.  A simple system is provided in which each of the rolls is provided with an encoder.          The encoder of a center roll of fixed diameter produces a fixed number of pulses per revolution representing paper length and the pulses produced by the encoders of each of the winding stations are counted along with the pulses produced by the winder of the center fixed diameter roll for computing density from roll and angular parameters and basis weight.

Filed: 1991-04-26
Granted: 1995-09-12
Abstract: A precision resistor is formed in an integrated circuit by a diffused region created at the same time as transistor source/drain regions.  In a CMOS process, this N-type resistor region is formed in an N-well,  as is used for P-channel transistors.   The resistor formed using a deposited oxide layer as a mask, and this oxide layer is also used to create sidewall spacers for the transistor gates.   The sidewall spacers are used in creating self-aligned silicided areas over the source/drain regions, self-aligned with the gates, and the silicide is also used for contact areas for the resistor.  The value of the resistor is defined by the width of the deposited oxide layer left as a mask, but this does not require any critical alignment steps.

Granted: 2001-04-24
Abstract: The present invention concerns a method and assembly for wrapping paper rolls in a wrapping material (12). The method employs such wrapping material that incorporates a heat-meltable laminate layer (26). According to the method the paper roll (23) is rotated on support rolls (13), the wrapper (12) is guided about the roll (23) so that the laminate layer (26) comes against the roll, the wrapper (12) is adhered to the roll by applying energy onto the wrapper in order to attain the melting of the plastic film laminate, whereby the wrapper (12) adheres to the roll (23), and the roll (23) being rotated is wrapped into at least one turn of the wrapper. According to the invention the wrapper laminate layer is melted from the laminate side to adhere the wrapper to the roll being wrapped, and when necessary, the area and/or energy density of melting energy application onto the wrapper material is varied in the direction of the center axis of the roll in order to achieve a desired pattern of adherence. The assembly according to the invention comprises a melting unit, which is divided in at least two melting zones, and said melting zones can be controlled partially or entirely independently from each other and can be directed against the surface of the wrapper material (12) in order to produce the thermal effect necessary for at least a partial melting of said laminate layer (26).
