Title: Method of preparing a modified corn steep liquor product
Inventor: WALSEM HENDRIK JOHAN VAN
IPC: B01J39/04
Filed: 2001-10-03
Abstract: A method of preparing a modified corn steep liquor product from a corn steep liquor which includes suspended solids, high molecular weight compounds, phytic acid, and metal values includes the steps of: subjecting the corn steep liquor to ultrafiltration to remove the suspended solids and high molecular weight compounds; treating the product of step (a) with a phytase enzyme to convert the phytic acid to inositol-mono-phosphate; treating the product of step (b) with an acid phosphatase enzyme to convert the inositol-mono-phosphate to myo-inositol; adjusting the pH of the product of step (c) to from 7 to 9 inclusive using a soluble base which causes most or all of the Mg values to precipitate, and removing the precipitate; and contacting the product of step (d) with a strong acid cation chromatographic resin to produce a first fraction containing most of the remaining metal values and a second fraction containing most of the myo-inositol, the second fraction being the modified corn steep liquor product.

Title: Method for preparing of positive photolithographe image
Inventor: VELEVA RADKA G
IPC: G03C1/705
Filed: 1990-03-01
Abstract: The method applies to electronics and micro-electronics. The prepared photolithography image with unlimited photoresist has a high resolution, enhanced photo sensibility and good protecting properties of the photo resist layer. On the preliminary treated wafer under high vacuum a thin layer of silver sulphide is deposited by synchronous component evaporation. After the layer is irradiated with active emission through a testing stencil, the wafer is subjected to direct etching of the irradiated spots thus avoiding the necessity for photo resist development.

Patent CA-2001818-A1 (CA)
IPC: H01H83/02
Filed: 1989-10-20
Abstract: A resettable circuit interrupter in a ground fault detector circuit utilizes a housing which slideably retains a solenoid coil wound on a bobbin.  A contact carrier is attached to the bobbin and one or more moveable contacts are provided on the carrier opposite a corresponding set of fixed contacts. A plunger slides through a central passageway in the solenoid coil.  The bobbin is spring biased so that the contacts are in a normally open position.  In a manually resettable version, when the solenoid coil conducts a predetermined current, manually activating the plunger causes the plunger to magnetically couple to a footplate attached to the bobbin.          When a plunger spring returns the plunger to its original position, the bobbin and contact carrier move with it and the contacts are closed.  When the solenoid coil conducts insufficient current to magnetically couple the plunger and footplate, the bias springs maintain the contacts in the normally open position.  In an electrically resettable version the contacts may be reset by electromagnetic energy alone, without manual activation of the plunger.

Abstract: ABSTRACT OF THE DISCLOSURE     The present  invention relates to a process and an apparatus for producing standard gas mixtures for testing or calibrating highly sensitive analytical  instruments  such  as  an  atmosperic- pressure  ionization mass spectrometer (APIMS).  According to the invention, the following steps can be carried out: introducing the gas to be analyzed in a controlled way into the analyzing device; adding to the gas to be analyzed, calibrated amounts of gaseous species in order to apply the standard addition and internal standard generation methods;  introducing a blanc or zero gas into the analyzing device;  adding to the zero gas calibrated amounts of gaseous species  in  order  to  generate  controlled  mixtures  facilitating  the calibration of the analyzing device; diluting in a  controlled way the gas to be analyzed by the zero gas before introduction of the mixture into the analyzing device.    This  last point  is particularly relevant for very polluted, or toxic and/or corrosive gases.  The above steps are completed without the addition of contaminants, which is specially important when doing ultratrace level analysis.

Title: Machine for forming cylindrical bales of crop
Inventor: VIAUD JEAN
IPC: A01F15/07
Filed: 1990-05-28
Abstract: MACHINE FOR FORMING CYLINDRICAL BALES OF CROP         Abstract of the Disclosure The baling chamber of one type of round baler is defined by belts which are trained over rolls connected to a drive. Stones can enter the nip formed between the belts and some of the rolls, e.g., a lower front belt driving roll, and thereby cause poor tracking of the belts.  To reduce the problem, a shield device is snap-fit mounted on the roll.  The device includes a nip bridging plate an upright portion of which abuts the belt run advancing to the nip and a downwardly sloping lower portion of which bridges the nip.  Thus the device covers the nip preventing access to it by the stones, and stones which fall upon it slide down the sloping portion of the plate eventually to find their way harmlessly to the ground.
