Patent CA-1309246-C (CA)
Title: Apparatus for coating a web of material
Inventor: KNOP REINHARD
IPC: D21H23/36
Filed: 1988-03-23
Granted: 1992-10-27
Abstract: ABSTRACT             In known nozzle applicators the application chamber with the metering system following on the side where the paper leaves the chamber forms a structural unit.  Therefore, changing the coating angle by pivoting the metering system inevitably results in a change in the geometry of the application chamber with negative effects on the flow pattern in the chamber.          According to the invention the metering system is pivotable independent of the application chamber about an axis parallel to the axis of the backing roller and is sealed by a sealing element against the restriction of the chamber.  The invention allows for adjustment of the coating weight during coating of paper webs by changing the coating angle within a large range without negatively influencing the flow conditions in the application chamber.

Title: Anactinic hopping materials and method of preparation

Granted: 1992-12-22
Abstract: ANACTINIC HOPPING MATERIALS AND METHOD OF PREPARATION                           ABSTRACT    A hopping material useful as a kettle additive in preparing anactinic malt beverages is prepared by a method which includes first forming an aqueous suspension of crude hops, containing alpha acid  and cellulosic material and alkali hydroxide and an alkali boro-hydride.  The suspension, which has a pH above about 10.5, is heated to isomerize and reduce the alpha acids initially present in the hops.  The pH is lowered to about 2 to convert the reduced iso-alpha acids to their free acid forms so that they are adsorbed on cellulosic hop material in the reaction mixture.  The cellulosic material which now contains the free isomerized and reduced alpha acids is isolated and is useful as an anactinic kettle additive which can be stored for pro-longed periods with no decomposition.  If desired, the cellulosic material thus obtained can be further treated by adjusting the pH with an alkaline solution to obtain an aqueous solution containing only reduced iso-alpha acids, which is useful as an anactinic post-kettle additive, and a cellulosic material, which is useful as an anactinic kettle additive.

Abstract: ABSTRACT            A method  for conveying and depositing  an adhesive,  flexible material (28) by means of a flexible base (10) in right side up position and essentially maintaining its shape on a depositing station  (27).  The base  (10)  is supported by a   displaceable supporting device  (12)  equipped with a guiding  member  (18), which imparts a direction change to the base.  The supporting device at the deposition moves away the base below the material thus that this is deposited by means of free fall. The material (28) is positioned on the base (10) a distance from the delivery end of the supporting device (12) corresponding to the accele-ration distance of the base (10). One,  the rear end of the base (10)  is  fixedly attached against  displacement.  The base is teared away from the contact surface in that it is urged to make an abrupt direction change over a guiding member (18) having a very  small  curvature  radius  (r)  at  the  front  end  of  the supporting device. The supporting device (12) and the base (10 are simultaneously accelerated rearwardly at an acceleration, which shall be at least 1 g  (g = acceleration of gravity), preferably considerably bigger than 1 g.

Abstract: @ in a data transmission system where a computer side and a terminal side are connected with the aid of an optical fiber cable (FK), unauthorized tapping of light energy from some fiber in the cable can be detected. The transmitted signals are assumed to be shot-noise limited, i.e. the transmitted light is heavily superposed, whereby a large part of the transmitted light must be tapped off for listening. The computer side and terminal side contain level-sensing circuits (NVK1, NVK2) connected to respective receiver units (MD, MT) which send an alarm when tapping takes place. An optical fiber relay (RK) is connected between the fiber cable (FK) and the terminal side for short-circuiting this side in the case where a power failure can occur.
