Patent DE-19650405-A1 (DE)
Inventor: SCHAFFER WOLFRAM
IPC: F16D65/16
Filed: 1996-12-05
Abstract: The present invention concerns a wheel-mounted electro-mechanical brake (10), with a screw driving member (18) placed on a floating caliper (12) which can be driven by an electric motor and with which a friction brake pad (14) can be pressed against a brake disc (16), and a second friction brake pad (14) can be pressed, encounter a reaction force exerted above the floating caliper, against the other side of the brake disc (16). In order to a enable the braking system to release (10) in case of malfunction, it is suggested that the screw driving member (18) be designed anti-self-locking, that a ball screw nut (20) and a threaded nut (22) be rotatively mounted and that the threaded nut (22) be locked using a removable anti-rotation device (46). In case of malfunction, the anti-rotation device (46) is released, so that the friction brake pad (14), strongly pressed against the brake disc (16), exerts a pressure on the threaded nut (22), thereby moving the latter (22) rotatively away from the brake disc (16).

Inventor: CONSTANTIN YVES
IPC: A01J25/12
Filed: 1997-02-07
Abstract: The invention relates to a method for the preparation of cheeses and to a device implementing this method. The invention is characterized by the insertion of curdled milk under pressure into a casing 3, possibly perforated, in order to carry out the moulding and the draining, followed by the cutting up of the casing filled with curdled milk into slices, the diameter of the casing and the thickness of the slices corresponding to the individual cheeses to be ripened. It allows the industrial manufacture of cheeses by eliminating or greatly reducing the costs related to the traditional use of moulds. The device comprises a forcing tube 1, fed with curdled milk by a pump 2. A ring 6 controls the partial sealing of and the braking of the casing. Alternatively, a first ring 10 controls the braking of the casing and a second ring 6 allows the controlled expulsion of the whey. The expulsion of the whey can be through perforations 7 in the forcing tube and a pipe 8 connecting the perforations to a vacuum collecting chamber 9.

Title: Controlling fuel supply to internal combustion engine
Inventor: BERGER JOACHIM
IPC: F02B3/06
Filed: 1997-02-13
Abstract: Internal combustion engines without controlled ignition such as diesel engines may be protected from excessive pressure in any cylinder by using pressure sensors (110,112,113,114) on each cylinder which send pressure signals to a control unit (150).The control unit (150) also receives other signals such as engine speed (N) and accelerator position (FP). Signals (A1,A2) are sent from the control unit (150) to devices (142,144) which are attached to a fuel pump (140) and regulate the quantity of fuel supplied and the starting time. If cylinder pressure exceeds a threshold pressure the start of injection is retarded and/or the quantity of fuel supplied is diminished.

Title: Indicating direction of current short circuit to earth in MV 3 phase AC network
Inventor: SCHUCK HANS LUDWIG DIPL ING
IPC: G01R31/02
Filed: 1997-07-25
Abstract: The method for indicating the direction of the short circuit to earth, compares the phase angle of the earth short circuit current and voltage. A change transmitter (1) essentially consisting of a ring shaped iron yoke is provided, which transmits an angle true 50 Hz signal of the earth short circuit current. The voltages of the local low voltage network (6) are related, so that an earth shorting direction, can be established in stations, without conventional current and voltage converters. A monitoring of the phase angle of the earth short circuit current and the voltages of the local LV network is carried out. So that an electric value with a zero passage (23, 24, 25) or a maximum, opens a time window (17) of a determined duration, and the other electric values with their zero passage or maximum, produce a signal pulse (26) or (27). Which if this happens during an open time window (17), forms DC signal pulsing with 50 Hz, which indicates a positive earth short circuit current direction.

Title: Operation of lean-burn fuel-injected diesel and petrol engines
Inventor: LEPPERHOFF GERHARD DR
IPC: F02D41/14
Filed: 1997-10-23
Abstract: Following conventionally controlled, metered fuel injection into a cylinder, once the combustion phase is over, additional fuel is injected. This occurs in the region of bottom dead center, following expansion. Exhaust subsequently passes through one or more treatment stages (10,11) of mechanical (soot filter), chemical or catalytic nature, to remove pollutants. Preferred features: Additional fuel is injected, once the mean gas temperature in the cylinder is below the sooting temperature of 1300 deg K. The quantity is metered over time, such that neither gas in the cylinder, nor gas after leaving, reaches sooting temperature. Additional injection takes place at latest, 110 deg  after bottom dead center. Additional fuel is metered, to relate exhaust NOx concentration, to a C1 equivalent (further detailed in text). Metering assures that the mean exhaust fuel air ratio is 0.95. Waste gas temperature before the soot filter is kept below 850 deg C. Of pollutants present, at least the NOx content is measured before treatment, allowing the engine management system (5) to determine the required additional quantity. Additional fuel injection quantities are entered as a matrix in the engine management unit, for each revolution of the engine.
