Title: Enzyme composition for retarding staling of baked goods
Inventor: BOWLES LINDA K
IPC: A21D8/04
Filed: 1991-08-26
Abstract: ABSTRACT     An enzyme composition comprised of an acid stable microbial alpha-amylase enzyme and a bacterial alpha-amylase enzyme retards the staling of baked goods at low dosage levels without adversely affecting the organoleptic characteristics of the baked goods and without significant gumminess.  The composition can be added to the dough or sponge in a process for making bakery products.  The acid-stable microbial alpha-amylase enzyme has an optimum activity at a pH of about 3.0 to about 5.0 at a temperature of about 60 to about 75°C and the bacterial alpha-amylase enzyme has an optimum activity at a pH of about 5.0 to about 7.0 at a temperature of about 100 to about 110°C.  The ratio of acid-stable enzyme to bacterial enzyme in terms of units per gram of flour is from about 0.05:0.005 to about 1.0:0.1.

Title: Variable gate flow analyzing method and apparatus
Inventor: CARSON DOUGLAS T
IPC: G05D16/20
Filed: 1991-10-02
Abstract: ABSTRACT OF THE DISCLOSURE    To measure flow rates,  the cross-sectional shape of the flow path is changed by inserting a multiple position gate into the flow path and altering the position of the gate to maintain the head of liquid constant with a reduced flow cross section.  To maintain the head at a desirable range, the depth is measured and controls the position of the gate as a feedback signal.  The position of the multiple position gate is correlated with the depth to provide an indication of flow rate.  For this purpose, a flow path housing is clamped to a pipe and a multiple position gate is moved by pneumatic pressure into the flow stream to change the flow cross section.   The depth of the head upstream of the gate is measured and the position of the gate is measured.   Flow rate is determined  from these two measurements.   Sampling may be performed at an increased depth caused by the gate.

Title: Column analyzer system and improved chromatograph column for use in the system
Inventor: SANFORD JAMES R M
IPC: G01N30/82
Filed: 1992-07-20
Abstract: ABSTRACT OF THE DISCLOSURE     An analyzer system for automatic column chromatography includes chromatographic columns which are mounted in a rack.          A drop removal mechanism system shakes the rack to transfer the last drop of eluate from the tip of a chromatographic column to a receptacle below the tip before the column is repositioned over another receptacle and another fluid or operation is introduced into the column.  This prevents one eluate from contaminating another.  The chromatographic column may have an upper end which is sealed by a foil member.  During use, the foil member is ruptured by lowering a pressure cylinder with a seal-punching head against it.          The pressure cylinder, which is part of the pressure tip unit, is then withdrawn so that fluid can be introduced into the column via the ruptured foil member.  The pressure tip unit is then lowered into sealing engagement with the column so that pressure can be applied via a bore in the pressure cylinder.  The column may also have a tip portion which is originally sealed by a removable cap.  The rack has a plate with aperture that is configured to receive the tip portion of the column and to provide a bearing surface for a spring member which removes the cap.  This spring member is lowered through the aperture, and the bearing surface forces it toward the tip portion so that the cap can be pushed off.

Abstract: The optical sensing device and the method thereof are for measuring a physical parameter. The device is to be connected to a light source which generates a multiple frequency light signal having predetermined spectral characteristics. The device comprises a Fabry-Perot interferometer through which the light signal is passed, an optical focusing device for focusing at least a portion of the light signal outgoing from the Fabry-Perot interferometer, and a Fizeau interferometer through which the focused light signal is passed. The Fabry-Perot interferometer includes two semi-reflecting mirrors substantially parallel to one another and spaced by a given distance so as to define a Fabry-Perot cavity having transmittance or reflectance properties which are affected by the physical parameter and which cause the spectral properties of the light signal to vary in response to the physical parameter. The Fabry-Perot interferometer is provided with at least one optical fiber for transmitting the light signal into the Fabry-Perot cavity and for collecting the portion of the light signal outgoing thereof.      The Fizeau interferometer includes an optical wedge forming a wedge-profiled Fizeau cavity from which exits a spatially-spread light signal indicative of the transmittance or reflectance properties of the Fabry-Perot interferometer.      The physical parameter can be determined by means of the spatially-spread light signal.

Abstract: The cushioning element is formed of two plastics film webs (1, 2) superimposed on one another and connected together by means of first weld seams (3) and second weld seams (4). Two mutually adjacent first weld seams (3) and second weld seams (4) form in each case a chamber which, during the production process of the cushioning element, can be filled partly or fully with air or left unfilled, as required. In this manner, cushioning elements of which the shape can be individually adapted to an article (6) to be packaged can be produced. Preferably the cushioning element is provided for surrounding an article (6) to be packaged on at least three sides and, similar to a book cover, comprises a top side (7), a spine (9) and a bottom side (8). The cushioning element has the advantages that the advantages of moulded packaging parts can be obtained for a very small amount of material, the disposal being possible in an extremely small space by cutting open the air-filled chambers. Since it is provided to produce the cushioning elements, preferably at the frequency at which they are used, using an apparatus installed near to the place of use, the space requirement for the packaging material is practically negligible. <IMAGE>
