Title: Solution for peritoneal dialysis or infusion comprising heat sterilized solutions one containing calcium and glucose and the other bicarbonate
Inventor: KNERR THOMAS DR
IPC: A61K33/06
Filed: 1997-10-31
Abstract: A solution for peritoneal dialysis or infusion comprises two separate solutions in a double-chambered pouch, one of which (containing calcium ions and glucose) is acidified to a pH of less than 3.2, while the other contains bicarbonate.  A solution for peritoneal dialysis or infusion comprises two separate solutions, which are mixed together after heat sterilization.  One solution contains calcium ions, other electrolyte salts and glucose in an osmotically active concentration, while the other solution contains bicarbonate and the salt of a weak acid with a pKa of less than 5.  The first solution is acidified with a physiologically acceptable acid to give a pH of less than 3.2, and the bicarbonate content of the second solution is fixed so that the concentration of bicarbonate does not exceed 10 mmol/l.   An Independent claim is also included for a double-chambered pouch for the two solutions, which is made of plastic.  The wall separating the two solutions may be broken by applying pressure to either of the chambers.

Title: Press-fit hose coupling
Inventor: THOMAS UDO DIPL ING
IPC: F16L47/24
Filed: 1997-11-07
Abstract: A press-fit hose coupling has a nozzle (20) onto which the female coupling is clipped.

Patent DE-19755140-A1 (DE)
Title: Circuit for use with e.g. motor vehicle IC engine ignition coil
Inventor: MIWA TETSUYA
IPC: F02P1/00
Filed: 1997-12-11
Abstract: The ignition coil 1 has a primary 11 and a secondary 12 coil that are coupled by a zener diode 13 to the voltage terminal Va. The primary current is controlled by a switch 20.

This ensures a switching voltage of less than 1.18kV results during ignition and that the induced voltage in the secondary is reduced.
Patent DE-19758030-A1 (DE)
Title: Electric brake system
Inventor: SUZUKI YOSHIHIKO
IPC: B60T17/22
Filed: 1997-12-29
Abstract: A piston (1a) moving in the main electric brake body (10) applies pressure to the friction shoe and an ignition switch detector (7) checks for key on or off settings. A brake command director element (5) checks the pedal state (3) as well as an element (6) checking the position of the parking etc brake. Sensor (1d) detects when the piston is in the main brake body (10) and an electric adjuster (1c) is used to actuate the piston when in the main body. A brake controller automatically sets the brake shoe clearance. The controller ensures smooth electrical braking by placing the piston in its initial position whenever the ignition switch is placed in its switched-on position. The piston setting is obtained by moving this back to the required shoe clearance. The piston is returned to the adjusted position when the pedal issues a braking command and then retracts it.

Patent DE-19804677-A1 (DE)
Title: Control of inlet valve open time for an internal combustion engine
Inventor: NITSCHE HANSJOERG
IPC: F02D41/34
Filed: 1998-02-06
Abstract: For a fixed induction manifold air flow rate and an injection nozzle size, the opening time required by a cylinder inlet valve (40) is computed as a function of the pressure differential between the nozzle upstream fuel pressure, P1 and the induction manifold back-pressure, P2. An air flow controlled by a butterfly damper (30) in an induction manifold (18) is dosed with petrol via an injection nozzle (14), from a fuel pump (11) maintained at a set point pressure P1 =4 bar by pressure regulator (20). The back pressure , P2 then varies with the butterfly opening,  alpha  and the engine rotation speed ; its value can be computed from the air mass flow rate but is preferably measured directly by a sensor (34).

Title: Obstruction recognition and signalling method especially for vehicles
Inventor: NAOYA AZUMA
IPC: G01S15/931
Filed: 1998-05-15
Abstract: The method involves using several transducers which transmit ultrasound wave impulse signals and which receive ultra sound waves reflected by an obstruction. A control unit is connected to the transducers for receiving the output signals of the transducers and determining the position and the distance of the obstruction using the output signals. An allocated alarm unit is activated according to the determined result.  The transducer transmits the ultra sound waves impulse signals with different frequencies. At least one frequency is higher (f1) and one is lower (f2). The control unit causes the alarm unit to output at least one alarm sound with a frequency corresponding to one of the frequencies f1 or f2 which is allocated to the transducer with the shortest distance to the obstruction. The output frequency has a cycle T which corresponds to the distance of the transducer to the obstruction.

Patent DE-19835916-A1 (DE)
Inventor: LIEBERMANN JOHANNES
IPC: H01B19/04
Filed: 1998-08-07
Abstract: The present invention relates to an isolator (1) that comprises a moulded body (2) made of ceramic (K) as well as a hydrophobic coating applied on the surface of said moulded body (2). The hydrophobic coating consists of a plasma polymer (P) and is applied directly on the ceramic (K). The traditional glaze at the surface of the ceramic (K) is replaced with the plasma polymer (P). An isolator of this type exhibits a high long-run stability in terms of electric isolation capacities. This system eliminates any need for a complex design of the moulded body (2) with a view to increase the travelling distance at the surface of the ceramic (K) and also eliminates any need for a glaze application, thus substantially reducing the production costs.
