Patent CA-2066511-C (CA)
Title: Apparatus for the emptying of a plate press during the manufacture of laminated sheets
Inventor: GOTZ WOLFGANG
IPC: B30B7/02
Filed: 1992-04-21
Granted: 2000-11-21
Abstract: An apparatus for the emptying of a plate press during the manufacture of laminated plates, the plate press having a lower press plate and an upper press plate, includes an arrangement for the picking-up of fully pressed laminated sheets at the discharge side of the opened plate press to form an entry mouth between the lower press plate and the laminated sheet, and a conveyor tray which is insertable into the entry mouth to thereby pick-up the laminated sheet, which is removable from the opened plate press while supported on the conveyor tray.  A suction lifter arrangement is provided at the discharge side of the plate press and includes suction lifters which are movable into the opened plate press and lowerable onto a fully pressed laminated sheet in the press.  The laminated sheet is lifted by way of the suction lifters to form the entry mouth.  A laminated sheet receiving table is positioned at the discharge side of the plate press and is hoistable or lowerable.  The conveyor tray while supporting a picked-up laminated sheet is movable over the laminated sheet receiving table and the laminated sheet is positioned onto the laminated sheet receiving table or onto laminated sheets already supported thereon by a reverse movement of the conveyor tray.  The suction lifters act on the surface of a fully pressed laminated sheet, but only in a peripheral region and only for a very short time so that disturbances of the surface structure of the sheet are substantially prevented.

Title: Ceramic binder and use thereof
Inventor: MOGENSEN GURLI
IPC: C01F7/57
Filed: 1992-04-22
Granted: 1997-02-11
Abstract: A ceramic binder is provided herein.  It comprises a sol-gel of a mixture of an aluminum tridecamer and at least one  low  charged metal  hydroxy cation.    The  aluminum tridecamer and the metal hydroxy cation together, are able to form an aqueous sol.  The aluminum tridecamer and the low charged metal hydroxy cation are present in the binder in  amounts  effective  for  binding  powders,  fibres  or mixtures thereof in a ceramic material.  Thus, the binder may be combined with powders and fibres before forming and processing into ceramic ware.  This allows defects in the mouldings to be easily corrected at the green stage in the cycle.

Patent CA-2100155-C (CA)
Inventor: CLARK ALLEN V
IPC: A23L3/015
Filed: 1993-07-08
Granted: 1997-09-30
Abstract: Fresh squeezed single-strength citrus juice or other juices are homogenized under an ultra-high pressure of about 15,000 psi.  Surprisingly, the ultra-high pressure homogenized juice exhibits an increased shelf life and decreased microbiological activity compared to juice homogenized under conventional pressures.  The microbiological activity present in the juice is significantly reduced despite the fact that no pasteurization step is conducted.  Single-strength juice processed in this manner maintains good flavor and palatability for 40 days at a storage temperature of 40°F or lower compared to less than one-half this shelf life for untreated juice.

Patent CA-2102666-C (CA)
Inventor: NAKAZAWA MASAHIKO
IPC: F16K11/16
Filed: 1993-11-08
Granted: 2003-12-30
Abstract: A flow control device has a case formed in a lower portion thereof with a fluid channel and a disk seat at an intermediate portion of the channel. A spindle housed in the case has a disk at its lower end and a rollable member at its upper end and is biased by a spring to press the disk against the seat. The case is provided in an upper portion thereof with a rotary shaft having an upwardly projecting handle or sidewise projecting lever handle. The shaft has a rollable member seat which is annular or circular-arc when seen from above and which is formed with a protuberance for lifting and lowering the rollable member as placed on its seat. Rotation of the shaft moves the protuberance, which in turn raises the rollable member to lift the spindle and hold the disk away from the disk seat. The rotation of the shaft reliably opens or closes the channel, or reliably effects a change-over between fluid channels. The seal face of the disk is less prone to abrasion or damage, will not displace the handle when the disk is thereby closed and is highly durable. The fluid channel within the device can be completely sealed off, so that the device is advantageously usable as a sanitary valve.

Abstract: A splice for regenerated cellulose tubular food casing. The splice includes a splicing tape comprising a regenerated cellulose film coated on at least one surface with a polyvinylidene chloride polymer (saran) and having a film thickness of 0.002 to 0.01 inches. The splicing tape is perforated to remove from ten to thirty percent of the area of the film. The removal of material from the splicing tape provides an elongation at break of at least twenty percent at a tensile force of between 500 and 1250 psi in a direction transverse to the direction of the longitudinal axis of the casing. The break force in that direction should be at least 100 psi greater than the force required to obtain the desired elongation. To form the splice, the splicing tape is wrapped around and sealed at the coated surface to a leading end of a first regenerated cellulose tubular food casing and a trailing end of a second regenerated cellulose tubular food casing wherein the ends are proximate each other.
