Title: Variable weight playball
Inventor: SPECTOR DONALD
IPC: A63B43/04
Filed: 1994-08-08
Abstract: A variable-weight playball whose outer casing is formed of liquid-impervious, flexible material, having a closable port therein.  Confined within the casing is a compressible body having the same configuration which depends on whether the ball is spherical or in some other shape.  The body is formed of low-density, open-cell, flexible foam plastic material having sponge-like properties.  To impart heft to the ball, water is introduced through the port into the body and absorbed thereby, the port then being closed to retain the water. To thereafter lighten the ball, the port is opened and the ball is squeezed to discharge water through the port until the ball has the desired reduced weight, after which the port is closed.  The casing may be contoured, printed or otherwise arranged so that the ball simulates the head of a humanoid or animal-like character having a mouth.  The port of the casing is integrated with the mouth of the character so that when water is added to the ball, it is seemingly introduced through the mouth.

Title: Optically non-linear active waveguiding material comprising donor and acceptor groups-containing triphenylcarbinols
Inventor: ENGBERSEN JOHANNES F J
IPC: G02F1/361
Filed: 1994-08-17
Abstract: ABSTRACT            The invention relates to an optically non-linear active waveguiding material comprising an optically transparent polymer and a donor group and acceptor group-containing triphenylcarbinol as a dopant. Said  dopants  have  a  high  hyperpolarisability  and  have a  charge-transfer absorption band which is about the same as that of their corresponding compounds  having  only one donor-?-acceptor unit.  The triphenylcarbinols were found to display good solubility in polymers. Nitro-functionalised triphenylcarbinols are preferred because of their charge-transfer absorption band at a low wavelength (Amax at about 290 nm). Aldehyde-functionalised calix(4)arenes were also found to have this low wavelength charge-transfer absorption band (Amax at about 270 nm).  Triphenyls  comprising  stilbene  donor-?-acceptor  units  are preferred because of their high hyperpolarisability.

Patent CA-2133489-A1 (CA)
Title: Apparatus and method for continuous high-volume steam cooking
Inventor: LEDET BRENT A
IPC: A23L5/10
Filed: 1994-10-03
Abstract: An improved apparatus and method for uniformly cooking thick layers of food product in a saturated steam environment. A foraminous conveyor belt transports a thick layer of food product into a walled cooking chamber open at its ends. The walls trap pure saturated steam to the exclusion of air in the upper region of the chamber. A  pressurized source of cooking energy supplies steam through a network of steam pipes situated just below the level of the belt along its carryway through the upper region of the cooking chamber. The pipes, which span the width of the conveyor belt, include small, restricted openings uniformly distributed along the pipes. The openings form steam outlets. The pipes are oriented with the steam outlets facing the conveyor belt. Saturated steam is emitted through the outlets directed through the foraminous conveyor belt at a velocity great enough to penetrate the thick product layer to cook even the innermost product within the thick layer, thereby improving the uniformity of the cook. The thick product layer slows the steam as it penetrates the layer to prevent the formation of turbulent flow paths that could draw unwanted air into the 212°F (100°C) saturated steam cooking region. An S-shaped back-flip in the conveying path repositions the product on the belt to further improve cooking uniformity.

Title: Apparatus and method for biological treatment of organic substances
Inventor: SONNEN KLAUS
IPC: B09C1/08
Filed: 1994-10-04
Abstract: The invention relates to an apparatus for and a method of bio-logically treating organic matter. The invention provides a variable-volume containment system suitable for transportation by conventional carrier vehicles. That makes the system suit-able for use as a stationary installation (off-site) as well as a mobile one (on-site).  The apparatus comprises at least two end segments which are adapted to be linked so as to form a closed unit to be sealed upon loading with the material to be treated so that the biological process may take place in a closed, sealed system.  In this manner, power consumption is distinctly reduced since the gas volume to be transported and/or handled can be lowered considerably as compared to con-ventional installations. The sealed containment of the system makes it possible either to actively conduct in a circuit all the gases which escape from the material or are released dur-ing the biological process or to scrub them by means of ade-quate filters before releasing them into the environment. Monitoring of the gas composition, at the same time, may be utilized for process control.  Moreover, the system poses no problem in terms of approval regulations because the treatment of the material as well as monitoring and control of process relevant parameters all take place inside the closed system so that there will be no contact between people and the matter to be treated or the resulting gases during treatment.  Further-more, the instant invention is especially well suited for fully automated process operations.  The invention also relates to a method by which the biological process in the closed system can be given optimum enhancement by the handling and specific aeration of the material. The kind of ventilation ap-plied clearly improves the circulation of air throughout the material and, as a consequence, the supply of oxygen to the microorganisms. At the same time, it serves as a safety means of the integrity of the system because vacuum applied to the system prevents any undesired escape of gas into the surround-ings even if leakage should occur in the system.
