Title: Method and circuit for partial correction of the drawing during the colour image reproduction
Inventor: KLIE JURGEN
IPC: G03F3/08
Filed: 1980-09-10
Granted: 1984-12-20
Abstract: PCT No. PCT/DE80/00133 Sec. 371 Date May 4, 1982 Sec. 102(e) Date May 4, 1982 PCT Filed Sep. 10, 1980 PCT Pub. No. WO82/00902 PCT Pub. Date Mar. 18, 1982.The invention relates to a method for improving the delineation in color image reproduction by means of a partial, electronic retouch. The color values of the individual color separations gained by means of image point-wise, trichromatic color image scanning and digitization are deposited in a storage medium (1). In order to improve the delineation, the color values of a color separation are altered image point-wise by means of selectable quotas of the image point-wise allocated color values of at least one other color separation. The quotas of the color values respectively represent the smallest amount of change for the color values of the color separation to be partially retouched. A retouch factor is determined for each color value of an image point to be retouched which is marked by the retoucher by means of the coordinate pen (51) of a coordinate identifier device (50; 51; 52), said retouch factor specifying the degree of retouch as a plurality of the change amounts to be added per image point. Locus-dependent correction values for the color values of the color separation to be retouched are calculated from the change amounts and from the retouch factors. For the purpose of visual control, the unretouched or retouched image is displayed on a monitor (2).

Title: Method of producing multiple coil, multiple tube heat exchanger
Inventor: MOLITOR VICTOR
IPC: F28F9/00
Filed: 1980-05-16
Granted: 1987-04-09
Abstract: A method of producing a multiple coil, multiple tube heat exchanger from circular tubes, in which alternating turns in each coil have a warmer liquid and other turns a cooler liquid, by coating the outside of each coil (C<u1>u) with a heat conductive mastic and winding the next coil (C<u2>u) against the mastic to force the mastic into spaces between adjoining tubes of the first coil, into spaces of adjoining tubes of the second coil, and into spaces between opposed tubes of the first and second coils. Mastic (34) is applied to the outside of each coil or into grooves between turns as the next coil is wound. Double tubes of each coil are preferably wound into grooves between turns of preceding coil, with the second tube of each coil started across coil from the first tube and continued at end of the coil past the first tube. Succeeding coils are wound against the mastic in same manner. Turns of the first coil (C<u1>u) are attached together, as by soldering, while the first and last turns of succeeding coils are similarily attached to adjacent turns of the coil beneath. Succeeding coils (C<u2>u) may be terminated between second and third turns of coil beneath, or with appropriate inner diameter of the first coil (C<u1>u), terminated between the last two turns of coil beneath. Several coils may be formed of tubing of the same diameter, with additional coils of tubing of greater diameter, all coils of tubing of same diameter, or all coils of tubing of successively increasing diameter. Length of the coils proportioned with respect to diameter of tubing so that the liquid will take the same amount of time to flow from one end of each coil to the other.

Title: Aroma-generating unit
Inventor: SPECTOR DONALD
IPC: A61L9/03
Filed: 1983-08-22
Granted: 1987-12-10
Abstract: An aroma-generating unit adapted to periodically discharge into the atmosphere bursts of aromatic vapor, the non-aromatic intervals between the bursts having a duration sufficient to avoid desensitizing the olfactory response of those exposed to the unit. The unit includes a hollow case whose upper wall has a vent therein and whose side wall has a slot to receive a replaceable cartridge provided with a porous mat impregnated with an aromatic liquid. When fully inserted the cartridge is disposed below the vent and serves to define an air-confined chamber within the case. Disposed in this chamber is an electrical heater that is periodically energized by power pulses to heat and expand the confined air and to produce a positive pressure in the chamber forcing the heated air through the impregnated mat to rapidly volatilize the liquid and to produce bursts of aroma which are discharged into the atmosphere through the vent, which bursts are separated by relatively long, non-aromatic intervals.

Abstract: In a centrifugal pump containing a sealing shroud the pump impeller is mounted only radially for rotation on a stationary axle or shaft. The stationary axle or shaft is fixed in the suction connection by means of wing rib supports or ribs and possesses an equalizing channel which connects the pump chamber portion at the rear of the pump impeller with the suction connection. This pump chamber portion at the rear of the pump impeller is connected with the delivery or pressure connection, whereas the pump chamber portion at the front side of the pump impeller is also connected with the suction connection as well as with the delivery or pressure connection. Advantageously, throttling rings are provided for self-metering throughflow throttling, depending on the axial position of the pump impeller. Additionally, the throughflow can be regulated by a throttling screw which is provided for the equalizing channel.

Abstract: A gel-forming composition comprising a first substance selected from the group consisting of a polyvinyl alcohol, a polyvinyl alcohol copolymer, and mixtures thereof, aldehyde operable for cross-linking with the first substance, and water. The gel-forming composition is useful for filling voids in porous substances and for retarding the flow of fluids in subterranean formations. For example, a method is provided for retarding the flow of fluids in high permeability channels in an oil reservoir. Such method is particularly useful in waterflood operations to increase the sweep efficiency of the oil recovery process. Since these gels have very good stability at elevated temperature they can be used in reservoirs having an average in situ temperature of 80<o>C or higher.
