Title: Control of fuel mixture enrichment during change-down of automatic gearbox
Inventor: HEDSTROEM LARS GUNNAR
IPC: F02D45/00
Filed: 1995-03-14
Abstract: A procedure for automatic computer-controlled gear-changing for a car (with auto gearbox) that accelerates down-changes has the engine torque temporarily reduced when a gear is disengaged, followed by a temporary enriching of the fuel mixture. Before the engagement of the lower gear, the engine is brought to synchronism with the speed of this lower gear by this enrichment. The fuel enrichment would be about 20% for normal down-changes, but if a kick-down situation is called for, or a mountain-travel program is in force with a large gas pedal deflection, or if engine braking is called for, then the fuel enrichment is between 50% and 100%.

Patent DE-19516323-A1 (DE)
Title: Prodn. of magnetisable aq. dispersions
Inventor: GUENTHER DIRK DIPL CHEM
IPC: C07K1/24
Filed: 1995-04-27
Abstract: A process for producing magnetisable dispersions of finely divided particles in water, is new. The particles consist exclusively or primarily of Fe3O4 and/or  psi -Fe2O3, have a size of 5-50 nm and are coated with a monomolecular adsorption layer of an organic substance. The substance is bonded to the particle surface through a functional gp., e.g. a carboxy, sulphonate, sulphate, thiol, phosphate or phosphonate gp., and has \- 1 other functional gp. available for surface-modifying chemical reactions. The process is characterised in that the chemical reactions are performed in such a way that the sedimentation stability is reversibly adjustable by means of pH displacement. The pH is first displaced into the acidic range until no dispersion in the aq. system occurs, the water is then sepd., and the pH is reset to a sufficient value of the polarity and water-solubility of the polar hydrophilic gps.

Title: Central heating system circulating electrically heated liquid medium
Inventor: MERK KARL
IPC: F24H1/22
Filed: 1995-09-27
Abstract: The heating system consists of a pump, controlled by a room thermostat, which circulates water or oil through a series of electric heating elements and a room radiator and a mechanical switching unit, controlled by thermostats associated with the heating elements, and an electronic control unit for overall regulation. The heating elements (3a,b,c) are U-shaped tubes (25a,b,c) containing coiled electrical resistance wire (26a,b,c) separately switched by a mechanical rotary switch (15), which is so arranged that all the elements can not be in the on condition at the same time. Thermostats (14a,b,c) govern the rotary switch position. A circulation pump (6), controlled by room thermostats (20), passes the heating medium, usually water, through pipes housing the heating elements in series connection, and subsequently the room radiators (9). Water temperature and level sensors (16,17) protect the system from overheating and room thermostats (20) signal an electronic control unit (21) which switches the pump accordingly.
Patent DE-19541176-A1 (DE)
Title: Combustion engine with direct inert gas charge
Inventor: SCHMIEDER ERHARD
IPC: F02M26/41
Filed: 1995-11-04
Abstract: The engine has two cylinder cavities with pistons running the same way but with opposite working stroke sequences. These cavities are connected in the BDC zone by a transfer channel, which is only open when both pistons are at BDC. When the channel opens, high-pressure exhaust gas flows from one cylinder to the other one, which has just completed its induction stroke. The transferred exhaust gas can create an excess pressure charge, an expulsion charge or a levelling charge in laminar form, depending on the valve angle and the transfer flow channel cross section.

Title: Pressure control valve for power steering mechanism
Inventor: HAYASHI TETSUJI
IPC: B62D5/07
Filed: 1996-02-02
Abstract: The valve is made up of an aluminium body (1) with a pump port (P), an actuator part (4a) and a secondary orifice (B). A hole (2) is provided at the centre of the aluminium body. A spool part (3) made up of aluminium is inserted into the hole. The spool consists of a relief valve with a spring (13) and a steel ball (15).

Title: Actuator for torque transmission friction clutch - has shape memory metal element that is electrically heated to cause sudden change in length to operate coupling
Inventor: PFAENDLER THOMAS
IPC: F16D23/12
Filed: 1996-06-20
Abstract: A friction clutch coupling [1] is located between a flywheel [4] on the engine side and a pressure plate that is engaged by a spring plate [2]. The spring plate is subjected to an axial force to control engagement. The actuator [10] operates directly on the spring plate and is at the end of a hollow shaft [9] that locates in a carrier [7] and are coupled together by a bar of shape memory metal [16]. An electrical current applied via a slip ring raises the temperature above the limit for a metallurgical phase change to take place and the length of the bar changes. The clutch action i.e. engage and disengage, can advantageously be controlled via a central control unit, such as an electronic computer.
