Abstract: The invention provides a process for the production of a fermentable wort from cereal grains, comprising the steps of: (a) liquefaction of cereal material, with the aid of .alpha.-amylase and/or endoprotease activity, to obtain a liquefied mash; (b) saccharification of the said liquefied mash in the presence of .alpha.-amylase; (c) filtration of the liquefied and saccharified mash to obtain a fermentable wort, wherein at least one of the steps (a) and (b) above is carried out in the presence of an enzyme having exo-peptidase activity. Useful as enzymes having exo-peptidase activity are exopeptidases, preferably thermostable exopeptidases, such as the fungal amino-peptidases, but also thermostable carboxy-peptidases are useful. Particularly preferred according to the invention are amino-peptidases endogenous to Aspergillus fungi, more in particular A. niger, A. oryzae or A. sojae.
Patent CA-2246776-A1 (CA)
Inventor: GERBER TOBIAS MANFRIED
IPC: G05B11/28
Filed: 1998-09-08
Abstract: Method and circuit configuration for power control with low switching surges for electric loads which are divided electrically into at least two partial loads, whereby to achieve the required individual power, it is distributed largely uniformly among the partial loads in a certain power range. According to this method, three separate pulse pattern sequences A, B and C corresponding to the respective system half wave are formed from three successive system half waves (pattern period), with the negative half waves being rectified. Each pulse pattern sequence A, B and C switches at least one partial load over a predefined period (PWM period), with each pulse pattern A, B or C switching a maximum of 1/3 of the nominal power of a partial load (pulse pattern power) according to the maximum number of pulses per PWM period. By means of pulse width modulation (PWM) of at least one pulse pattern sequence in accordance with the total power demand, the respective load is switched over a preselectable PWM period by the number of pulses of the respective pulse pattern sequence A, B and/or C during this PWM period. The invention makes it possible to calculate in advance the current surge load of the system due to the loads and the adaptation of the loads to prevent interfering voltage changes in the power system.

Title: Method and apparatus for introducing glass gobs into a glass container forming machine
Inventor: GREENAWALT ROBERT J
IPC: C03B9/14
Filed: 1998-10-09
Abstract: A gob of molten glass from a gob delivery system is introduced into a blank mold of a glass container forming machine of the individual section type by way loading funnel immediately upstream of an opening into the blank mold. The loading funnel has an upper annular gathering portion in the shape of an inverted frustum of a cone and a cylindrical lower shaping and orienting section. The internal diameter of the shaping and orienting section is somewhat less than the outer diameter of a gob passing therethrough, to thereby contact the gob in a substantially circumferential pattern, and the shaping and orienting section has a length that is sufficient to precisely align the longitudinal central axis of the gob with a longitudinal central axis of the blank mold, to thereby eliminate or substantially eliminate the need to swab the interior of the, blank mold with a mold dopant composition.

Title: Method of explosives detection
Inventor: HILEY ROBIN WALTER
IPC: G01N33/22
Filed: 1997-06-10
Abstract: A method for detecting energetic materials, particularly explosives materials, in samples involves heating a mixture of a sample under a reduced pressure of not more than 100 mbar and detecting the chemiluminescent emission therefrom with a suitable light detector, for example a photomultiplier or photodiode. The sample is heated to a temperature in the region of from 300 °C to 500 °C. The mixture is conveniently heated in a quartz tube fumace placed within a vacuum chamber and the inlet to the tube furnace may be connected directly into the outlet from a gas chromatography apparatus such that individual compounds from a mixture may be detected as they pass sequentially through the chromatography apparatus and into the tube furnace. Where a carrier gas is used this may be an inert gas such as nitrogen, argon or helium or a specific gas to enhance the responsiveness of the method for a particular sample material. Apparatus for carrying out the method is also provided.

IPC: G01S17/875
Filed: 1998-09-28
Abstract: A system for determining the spatial position of a target having an active target adapted to emit energy in response to an active signal and a passive target adapted to reflect energy impinging upon such passive target from an active energy source. A common energy detector is provided for detecting both the energy emitted by the active target and the energy reflected by the passive target. A common processor is provided for determining the spatial positions of both the passive and active targets in response to the energy detected by the common detector. During a sensor cycle the spatial position of the active target is determined and during a sensor cycle the position of the passive target is determined. The sensor cycles may be interspersed or may be the same cycle to enable simultaneous determination of both the active target and the passive target during a single sensor cycle. The system also enables the determination of the spatial position and angular orientation of both a rigid object having affixed thereto active targets and/or another rigid object having affixed thereto passive targets and/or an object having affixed thereto both an active and passive targets.

Abstract: A stop and control box houses the standard phone pager (a COTS APPLICATION-meaning commercial off the shelf) as a stimulating and communication device in either a secured and/or concealed mechanical lockup or in any protected area that employs any means to limit access. This protected area would also house control circuitry and could house monitoring circuitry to interface with and record the host machine's functions and finally record the operator and occupant's activities. The stop and control box accomplishes its remote capabilities in a number of ways from actually being wired directly to the pagers circuitry to merely sensing or reading the pager functions and numerical pages.

Title: Methods for the detoxification of nitrile and/or amide compounds
Inventor: PIERCE GEORGE E
IPC: C12M1/00
Filed: 1997-12-18
Abstract: The present invention describes methods for the detoxification of a mixture of nitrile compounds, or a mixture of nitrile and amide compounds by conversion of the nitrile compound(s) to the corresponding amide or acid compounds using a pure culture of an induced microoranism strain capable of converting a nitrile moiety to an amide or acid moiety. If an amide is formed or is present in the mixture, the amide can be further converted, using the present methods for detoxification, to the corresponding acid. The acid can then, if desired, be further degraded to CO2, H2O and biomass. The induced pure cultures are able to detoxify a mixture of nitriles or a mixture of nitriles and amides which are typically present, in high concentration(s), in nitrile production waste streams. The present invention further discloses methods for removing a nitrile compound from an amide preparation, such as an acetamide or acrylamide preparation containing an unwanted nitrile compound, using an induced pure culture of an induced microorganism strain capable of converting a nitrile moiety to an amide or acid moiety. This invention also discloses kits, biofilters and methods for use of the kits and biofilters for detoxification containing the useful microorganism strains.
