Patent DE-4136553-A1 (DE)
Inventor: BRAHMBHATT HIMANSHU N
IPC: A61K39/00
Filed: 1991-11-06
Abstract: Lipopolysaccharide (LPS) and outer-membrane protein (OMP) preparations of Bordetella pertussis were incorporated into multilamellar liposomes composed of soya bean derived phospholipids. After oral or intranasal vaccination of mice with the coated liposomes, specific antibody responses were detected in lung washes. However, a specific IgA response to LPS could be detected after immunisation with only the OMP-coated liposomes and not with the LPS-coated liposomes suggesting adjuvant activity bestowed by the proteins. The OMP-coated liposomes were significantly more effective in inducing an immune response than the OMP preparation alone. Responses were highest when mice were given a booster 30 days after primary immunisation. The maximum response occurred 20 days after the booster but specific antibody could still be detected 75 days after secondary immunisation. These results suggest that this liposome antigen delivery system has potential in stimulating secretory antibody responses which may be necessary to effectively protect against infection from B. pertussis.

Title: Energy converter, for optionally converting thermal energy into mechanical or electrical energy, or vice versa
Inventor: SPANGENBERG KURT DIPL ING
IPC: H02K7/18
Filed: 1993-03-10
Abstract: Reversible gas working processes can generate mechanical energy from heat, or vice versa. Electric prime movers either convert mechanical energy into electrical, or vice versa. Combinations of the two can optionally be employed when it is possible without mechanical alteration of the elements of the gas working process to reverse the latter and yet to work economically. For this purpose, the invention employs valves under the control of an electronic computer which is programmed with all the gas working processes possible by means of the available elements, and with the data relating to the elements. Measuring sensors inform the computer of the instantaneous state of all moving parts and of the process gas, with the result that it can assign the optimum working process to the problem posed, and can control the elements accordingly. Reversibility and optimum thermal efficiency are achieved in this way. The mechanical efficiency is optimised by a low-friction design.   The device heats and cools and supplies current or mechanical motive (drive, driving) power. Use may be made of solar energy and all fuels.

Title: Method and apparatus for reducing the speed of a load which is dropping on a parachute
Inventor: EWALD JOCHEN DR ING
IPC: B64D17/78
Filed: 1993-08-05
Abstract: A method and an apparatus for reducing the rate of fall of a load which is dropping on a parachute, shortly before the load touches the ground. For sensitive payloads which fall to the ground at high speed on a parachute, the landing shock on touching the ground or else the rate of fall shortly before touching the ground must be greatly reduced in order to prevent damage to the payload resulting from excessively high deceleration forces. In order to reduce the rate of fall, a double flywheel is installed between the parachute and the payload, part of the supporting rope (cable) to the parachute being wound up on the shaft of the double flywheel and the payload being suspended under the double flywheel in the form of a gondola, such that it can rotate. On approaching the ground, an additional connecting rope between the parachute and the double flywheel is cut, so that the supporting rope can be unwound and the double flywheel thus caused to rotate. When the supporting rope has completely unwound, a translational movement reversal occurs during which the double flywheel, with the payload, is moved relatively towards the parachute. If the parameters of the apparatus (moment of inertia, wound-up rope length before cutting, etc.) are selected in such a manner that the relative speed between the double flywheel and the payload with respect to the parachute is approximately equal to the rate of fall of the parachute after the translational movement reversal, the resultant rate of fall of the ...

Title: Rinsing and cleansing device for sewer
Inventor: WILLEMS GILBERT DIPL ING
IPC: E03F9/00
Filed: 1993-12-14
Abstract: The pipe (17) is pivoted, and its intake opening is in fluid connection with the rinsing tank. In a first end position of the pipe, during initial filling of tank and pipe, the centre of gravity of pipe and fluid moves across the pipe pivot axis (25), into a second end position. Further filling of tank and pipe causes the centre of gravity to move back across the pivot axis. It returns the pipe into the first end position. The pipe is retained in the second position by fixing elements, which are released when the pipe moves back.
