Granted: 1993-07-20
Abstract: A B S T R A C T     A packaging and a method of packaging are disclosed.  The method involves providing a base (1), providing goods (3) over the base (1), providing a skin web (5) over the goods (3), skin packaging the goods between said skin web  (5) and the base (1), sealing a lid (7) over the skin web (5) with a desired gas between the lid (7) and said skin web (5) which will enhance the keeping qualities of the goods (3) by being able to permeate the skin web (5) and contact the goods (3), and following discolouration of the goods (3), such as red meats, with time, allowing a gas which will improve the colour of the goods (3) to contact the surface of the goods (3) without removal of the skin web (5).         The gas is able to contact the surface of the goods (3) by either peeling off the lid only and allowing the gas to permeate through skin web (5) or by providing aperture means through the lid (7) and the web (5) and allowing the gas to directly contact the surface of the goods (3).  In the latter alternative, the aperture means can be resealed.

Title: Method in an adjustable-crown roll as well as a roll device making use of the method
Inventor: NIKULAINEN OSMO
IPC: B30B3/00

Granted: 1991-04-09
Abstract: METHOD AND DEVICE IN AN ADJUSTABLE-CROWN ROLL       ABSTRACT OF THE DISCLOSURE           Method in a variable-crown roll in which hydraulic loading elements or a series of hydraulic loading elements are used . Such series of elements acts along a plane of n nip that can be formed between the variable-crown roll and a counter-roll thereof, with such elemencts or series being situated between central axle of the roll and a cylindrical mantle which is rotatble about the central axle through radial bearing. The central axle is supported by axle journals thereof on deflection bearings. In the method, the central axle is pivoted about the deflection bearings thereof over an angle which is within a range of about 30° to 180°. By the effect of such pivoting, the variable-crown roll and the mantle thereof are shifted away from the nip, so that the nip is opened. This shifting is produced by the axis of pivotion of the deflection bearings being situated by a certain eccentricity distance further away from a nip line of the closed nip, than the axis of rotation of the roll mantle.

Title: Apparatus and method for controlling the shears of a glassware forming machine
Inventor: GARDNER EDWARD B
IPC: G05B19/02
Filed: 1988-05-09
Granted: 1992-05-05
Abstract: ABSTRACT OF THE DISCLOSURE           A control system for controlling the operation of the shears of a glassware forming machine.  The control system incorporates sensors which produce signals representative of predetermined shear positions in each shear cycle, and in particular, makes use of the correlation between the duration of a Zero Crossover Signal and the point of maximum overlap of the shears.  The system adjusts the time of deactuation of a fluidic drive assembly, and therefore, the overlap displacement, if the termination of the Zero Crossover pulse falls outside a defined "deadband". The Zero Crossover signal may also be monitored to provide alarm signals or shut the system  down.

Patent CA-1290456-C (CA)
Title: Fast direct output during sort merge
Inventor: CHANG PHILIP Y
IPC: G06F12/00
Filed: 1989-01-25
Granted: 1991-10-08
Abstract: ABSTRACT OF THE DISCLOSURE      In a relational database system, a method is utilized that increases the performance of the sort operation.  An optimizer routine in the relational database manager analyzes a user's complete query to determine whether the final sorted results can be used directly by the user as sorting occurs.  If the sort results can be used, the sort results are sent to Relational Data Services in the relational database manager for output to the user.     Depending upon the determination made by the optimizer routine, one of two output modes for the final sorted sequence string of data are selected by the relational database manager.  In disk output mode, the last pass of the final sorted sequence string is written to disk.  In fast direct output mode, the records of data are sent to the user as the final sorted sequence string is being merged during the last pass.     The system and method of this invention reduces the total sort time by eliminating the overhead of writing to disk during the fast direct output mode. Also, the response time, or availability for each record is reduced since each record is retrieved or sent to the Relational Data Services immediately after it has been sorted into the final sort order instead of completing the entire sort first, and then writing to disk.

Title: Apparatus and method for photoetching of polyimides, and polycarbonates and polyetherimides
Inventor: LIU YUNG SHENG
IPC: C08J3/28
Filed: 1989-05-11
Granted: 1995-10-31
Abstract: Polyimides, polycarbonates, polyetherimides and other highly stable organic polymers are photoetched through the use of deep ultraviolet light produced by a broad area, non-coherent, continuous light source.  This method is effective in an oxygen-free environment, but provides slightly higher etch rates in an air ambient as a result of the oxygen in the air ambient.  The apparatus in which this photoetching occurs may employ a single light source or a plurality of side-by-side lamps and may include ports which allow continuous transport of samples therethrough.
