Title: Electrostatic gas cleaning
Inventor: CAMERON GORDON M
IPC: B03C3/014
Filed: 1989-11-01
Granted: 1999-08-17
Abstract: In the purification of gases generated in metallurgical and similar furnace operations, the impurities include solid particles and compounds or elements which are gaseous at the furnace temperatures and only form solid or liquid at temperatures approaching ambient conditions. Proper cleaning therefore requires cooling of the gases to at least the water dew point to cause these impurities to form as particles or droplets. This invention describes a process and apparatus for collecting such particles or droplets in which a charging device and condensation equipment are combined to provide a simple, yet effective apparatus at a fraction of the cost of conventional apparatus.

Title: Transmission system for digitised television images
Inventor: VAN DER MEER JAN
IPC: H04N5/926
Filed: 1991-02-19
Granted: 2001-01-16
Abstract: A series of images of a full motion video scene is divided into a number of sub-series which, when interleaved, represent the original series. A ranking order increasing magnitude is allocated to consecutive sub-series. Each image of a sub-series is converted into an image data block, while images from one or more sub-series having a lower order of precedence are considered for this conversion. A packet header indicating the ranking order of the sub-series with which the corresponding image is associated is added to each image data block.    The display apparatus is adapted to select those image data blocks which have predetermined packet headers and to subject the image data blocks thus selected to a decoding process. The number of different packet headers which is selected determines the temporal resolution of the scene to be displayed.

Title: Method and apparatus for stretching dough
Inventor: HAYASHI TORAHIKO
IPC: A21D8/02
Filed: 1991-05-09
Granted: 1995-02-14
Abstract: A dough-stretching roller apparatus is provided to produce a continuous web of dough in a process to manufacture confectionery and bread.  The apparatus includes a pair of upper rollers and a pair of lower rollers, a sensor means that measures the width of the dough that contacts the lower rollers, and a controller that controls a motor driving the upper rollers in response to a signal from the sensor means.  The controller increases the rotational speed of the upper rollers when the sensors detect that the width of dough is less than a preset width while the controller decreases the rotational speed of the upper rollers when the sensors detect that the width of the dough is greater than the preset width.  Thus, even if the quantity of dough supplied from a hopper is unstable, the stable production of a stretched web of dough having a constant volume over its length can be continued.

Granted: 1998-09-15
Abstract: A process for the selective hydrolysis of triglycerides to mixtures of 1,2 or 2,3-diacyl glycerides and 2-acyl glycerides is disclosed.  This process uses an alkyl alcohol selected from the group consisting of 2-methyl-2-propanol, 2-butanol and the primary, secondary or tertiary branched or straight chain alkyl alcohols having from 5 to 8 carbon atoms, and mixtures thereof, an aqueous buffer system and a 1,3-lipase.
