Title: Soil anti-redeposition agents
Inventor: KRINSKI THOMAS L
IPC: C11D3/00
Filed: 1991-08-30
Abstract: SOIL ANTI-REDEPOSITION AGENTS            ABSTRACT     A detergent  composition  and  method  may have the soil anti-redeposition   properties   significantly  and  unexpectedly improved  by  incorporating  into  the  detergent  composition an effective   amount   of   an   anti-redeposition   agent.     The anti-redeposition  agent is a modified vegetable protein material such  as  a  soy  protein isolate which has been modified with an ionic  monomer.    Ionic  monomers  which  have  been found to be especially   effective   at  improving   the   anti-redeposition properties   of   washing  detergent  compositions  are  cationic epoxide   monomers,   cationic  acrylate  monomers  and cationic chlorohydrin  monomers.    Anionic  or  carboxylated  soy protein derivatives    have    also    been   shown   to   be   effective anti-redeposition agents.

Title: Device for the slicing production of boards
Inventor: GOENNER SIEGMAR
IPC: B27L5/06
Filed: 1991-12-02
Abstract: A machine is described for the slicing removal of a board from a cant advanced longitudinally past a blade and pressed, from the side opposite from the blade, by means of a pressing device against the blade and a counterpressure rail mounted in front of the blade.  In contrast to conventional constructions, in which driven feed rollers for the cant are located before and beyond the actual slicing device, driven roller pairs are provided directly in the region over which the blade, which forms a very acute angle with the feed direction, extends.  The feed roller pairs are moreover floatingly journalled so that they do not affect the position of the cant.  By the novel arrangement, an overly lengthy force transmission path through the cant itself from the feed rollers to the blade is avoided.

Title: Method of substituting fonts and displaying characters
Inventor: WARNOCK JOHN E
IPC: G06K15/02
Filed: 1992-05-27
Abstract: ABSTRACT OF THE INVENTION The invention describes a method for reconstructing charac-ters in a document, which are expressed in one or more fonts, to convert the characters to a different font designed to closely match characters from a plurality of fonts in an aesthetically pleasing manner.  This is accomplished by first selecting a first character from the document and thereafter substituting for the first character the same character constructed from the different font and having the same width as the first character, the char-acters of varying widths within the different font being designed to have aesthetically pleasing relationships between their parts irrespective of width.  The construction and substitution of characters of the different font for each of the characters in said document needing reconstruction is continued in the same manner until all the characters in the document needing recon-struction have been substituted, thereby creating a reconstructed document having an aesthetically pleasing relationship among the characters in the document.  Thereafter the reconstructed docu-ment is stored, printed or displayed.

Patent CA-2070448-A1 (CA)
Inventor: SACKS RICHARD D
IPC: G01N1/22
Filed: 1992-06-04
Abstract: A gas chromatography system which incorporates a simplified sample injection system in which replaces conventional mechanical injection systems with one based strictly upon thermal trapping of a continuously supplied carrier gas and sample stream.  The carrier gas and sample stream pass continuously through the device which  incorporates a thermal  focusing chamber which communicates  with  the  inlet  end  of  a  gas  chromatography separation column.  By causing the focusing chamber temperature of a sample tube passing through the focusing chamber to be dropped, incoming components comprising the sample stream are condensed and trapped.  Injection into the column occurs rapidly heating the sample in the thermal focusing chamber causing a narrow sample plug to be introduced into the column.  Various embodiments of this invention are intended for operation for evaluating carrier gas and sample stream provided at a above atmospheric pressure, or which are drawn through the system by vacuum source at the outlet end of the column.   In addition, vacuum backflushing features are also described.

Title: Method for controlling a pipe bending machine
Inventor: SCHWARZE RIGOBERT
IPC: B21D7/14
Filed: 1992-08-18
Abstract: A pipe bending machine has a bending template (10) around which a pipe (13) is bent. The bending template (10) is provided with a position sensor (32) that detects the bending path in dependence on the rotational position. A pushing device (17) engages the unbent portion (13a) of the pipe and urges the same towards said bending template (10). The pushing device (17) is provided with a position sensor (30). The position signals (PS1, PS2) of the two position sensors (32, 30) are compared in a control circuit (41) and an actuation signal (SS) is generated for controlling a pressure controller (42) to adjust the pressure of the drive (22) of the pushing device (17). The actuation signal (SS) is generated such that, in the case of equal position signals (PS1, PS2;), the drive (22) of the pushing device (17) is supplied with a pressure that determines the upsetting force exerted on the pipe.

Title: Method for controlling the conversion of iron-containing reactor feed into iron carbide
Inventor: STEPHENS FRANK M JR
IPC: B01J8/24
Filed: 1991-07-23
Abstract: A process for controlling the conversion of reactor feed to iron carbide is disclosed. The reactor feed is subjected to a pro-cess gas in a fluidized bed reactor (10), and measurements (56) are taken of individual gases in the off-gas from this reaction and the temperature (64) and pressure (66). A stability phase diagram is generated based on the temperature. Different regions of the stability phase diagram are representative of different products being formed by the conversion of the reactor feed. Based on con-centrations of the individual gases in the off-gas and the total pressure, a point is plotted on the stability phase diagram indicative of the favored reaction product. The process parameters can then be adjusted to insure that iron carbide can be produced from the reactor feed based on the stability phase diagram.
