Title: Temperature-controlled pH-dependant formation of ionic polysaccharide gels
Inventor: CHENITE ABDELLATIF
IPC: C08L5/08
Filed: 1998-04-06
Granted: 2000-10-05
Abstract: The present invention relates a temperature-controlled pH-dependant formation of ionic polysaccharide gels, such as chitosan/organo-phosphate aqueous systems, and methods of preparation thereof. While chitosan aqueous solutions are pH-dependant gelating systems, the addition of a mono-phosphate dibasic salt of polyol or sugar to a chitosan aqueous solutions leads to further temperature-controlled pH-dependant gelation. Solid organo-phosphate salts (1-20% w/v) are added and dissolved at low temperature (10° C.) within 0.5 to 4.0% w/v chitosan in aqueous acidic solutions. Aqueous chitosan/organo-phosphate solutions are initially stored at low temperatures (4° C.), then endothermally gelated within the temperature range of 30 to 60° C. Chitosan/organo-phosphate solutions rapidly turn into gels at the desired gelation temperature. Gelation can be ex vivo within any receivers or molds, or in situ in animals or humans (in vivo) so as to fill a tissue defect or cavity.

Title: Header device
Inventor: NARITA HIROSHI
IPC: G06K13/08
Filed: 1987-11-04
Granted: 1990-08-30
Abstract: A header device (10) for receiving an IC card or pack (30), comprises a housing (11), which includes an IC-pack holder (12) having an opening (121) through which the IC pack (30) is inserted into and removed from the housing, and a pair of first levers (21) projecting into the IC-pack holder (12) so as to abut an end portion (31) of the IC pack (30), and a pair of second levers (22) located outside the holder. The first and second levers (22, 23) are coupled to each other at their respective proximal ends (211, 221), so that they are immovable relative to each other. The coupled levers (21, 22) are rotatably mounted on the housing (11). If the IC pack (30) is inserted into the housing (11) through the opening (12), the end portion (31) of the IC pack pushes the respective first levers (21), thereby rotating both the first and second levers (21, 22) in a first rotation direction. Then, if the second levers (22) are rotated in a second rotation direction reverse to the first rotation direction, the first levers (21) push the IC pack out of the housing.

Title: Control valve with sliding piston - has flexible sealing joints which prevent distortion of bore and possible binding of piston
IPC: F16K27/04
Filed: 1969-03-28
Abstract: The valve body consists of three parts, the base (1) the piston housing (2) and the cover (4). The piston housing has a central bore (7) which is a close sliding fit for the piston (3). This central bore (7) is intersected by transverse slots(6) which match similar slots in the base (1) and which communicate with inlet and outlet holes (22). The joints between the cover (4) and housing (2), and housing (2) and base (1) are sealed with flexible '0' rings (24). This method of construction prevents the housing (2) from being distorted by the loads imposed during tightening. Consequently the bore (7) and piston (3) can be made to work with a very fine clearance resulting in a very low lead rate.

Abstract: There is disclosed a coil structure which can be rapidly energized or excited, and which reduces the generation of heat in a coil container by an eddy current due to a dynamic disturbance such as vibration and a magnetic field fluctuation, thereby suppressing the occurrence a quench. The coil container is constituted by a low-resistivity material, and a high-resistivity portion is provided at at least one portion of the coil container in the direction of the periphery of the coil container. The high-resistivity portion is provided at a position where a vibration displacement is small or a magnetic field fluctuation is small. When the coil structure is to be energized or excited, the eddy current produced in the direction of the periphery of the superconducting-coil container can be reduced at the high-resistivity portion, and when the dynamic disturbance develops, the generation of heat by the eddy current is suppressed by the low-resistivity material.
