Filed: 1988-09-02
Abstract: The invention relates to a drive device for motor vehicles with all-wheel drive and with a viscous coupling in a rear drive train. According to the invention the drive gear train for the rear wheels is designed so that the ratio of the speed of an input shaft (8) of the viscous coupling (9) to the speed of the front wheels (3) of the motor vehicle is greater than the ratio of the speed of an output shaft (10) of the viscous coupling (9) divided by the speed of the rear wheels (3).

Title: Appliance for the distribution of superheated steam of constant and controllable quality in fabric treatment
Inventor: ALBERTO PIETRO
IPC: D06B19/00
Filed: 1988-09-09
Abstract: Appliance for the distribution of superheated steam of constant and controllable quality in fabric treatment, especially in autoclaves, during continuous operation. This appliance consists essentially of a leakproof container which receives at the inlet, by means of a valve, the steam coming from a boiler and which contains electrical heating resistors, the functioning of which is controlled by a thermostat regulating the steam temperature. The value set in the thermostat will depend on the calibration pressure of this valve and, at all events, will always be above the steam-saturation temperature at this specific pressure, so that "dry steam" is assured in all cases. <IMAGE>

Title: Reciprocating piston engine
IPC: F02B75/02
Filed: 1988-09-29
Abstract: Reciprocating piston engine comprising two crankshafts doubly coupled to one another. On the one hand the crankshaft axes are connected to one another by one or more mechanisms (for example gear train), on the other the cranks are coupled to one another by two connecting rods. The connecting rod of the piston can be fixed at any point of either of the two connecting rods of the crankshafts by a joint, according to the desired parameters (also on their common bearings). The transmission ratios of the two crankshafts and their phases can also be different depending on the required parameters. The cylinder is adjustable in relation to the crankshafts and the individual cylinders may be arranged both in a V and in line. The parameters of the drive system can be combined with one another so that a reciprocating movement of the piston is achieved in the four-stroke cycle with two virtually identical top dead centres and two different bottom dead centres. The shorter reciprocating movement of the piston corresponds to the intake and compression stroke and the longer reciprocating movement to the power and exhaust stroke. By means of the differentiated stroke lengths, an additional quantity of mechanical energy is achieved compared to the conventional four-stroke engine for the same quantity of fuel.
Patent DE-3834119-A1 (DE)
Title: Brake cooling flaps and air ducting system for vehicles
Inventor: KIRSCHNER PETER
IPC: B60K11/08
Filed: 1988-10-07
Abstract: In the effort to design aerodynamically sound vehicle bodies, front spoilers and other downwardly extending moulded body parts are chosen. The brakes need a supply of cooling air, however, and front spoilers therefore have corresponding permanent air passages or are for this reason kept flat and thereby cover only a relatively small part of the total air passage cross-section below the vehicle. This places limits on achievement of the optimum aerodynamic design. The invention is intended to remove the necessity for this technical compromise and to fully achieve both these objects. The brake cooling flaps are closed in unbraked travel and at the same time an integral component of the external shape, that is of the body or the front spoiler. In the opened condition, that is when brake cooling is required, that is generally during braking, the system allows slipstream cooling air to flow to the brake systems and in some embodiments assists the braking by increasing the air resistance and/or the negative lift force. According to the invention, in connection with the brake cooling flaps additional advantageous possibilities result for air ducting below and in the vehicle and for optimisation of the internal aerodynamics. The spheres of application are vehicle construction, car body construction, racing car engineering, spoiler construction.

Filed: 1988-11-02
Abstract: Creep and rotational movement monitoring in the case of a protection device having normal or enhanced safety, of type designation EBUD-00 (...99) for monitoring various safety aspects related to specific operating conditions of a target system.   a) monitoring the stationary state (special operation without movement), with the hazard zone open (protective cover or protective grid), no rotational movement may take place. b) monitoring the stationary state (special operation with movement), with the hazard zone open (protective cover or protective grid), only a limited creeping movement may take place for setting up the target system. c) rotational movement monitoring (normal operation) with the hazard zone closed (protective cover or protective grid), only the permitted, limited rotational movement may take place on the target system. d) the monitoring of the operating states and of the rotational movements must be subject to absolute functional reliability and must always result in disconnection of the drive power in the event of danger (double monitoring in one apparatus).

Title: Diagnosis and prevention of human parvovirus B19 infection - using synthetic penta- and higher peptide(s) and antibodies
Inventor: FRENZEL BERND DR
IPC: A61K39/00
Filed: 1989-11-29
Abstract: Diagnosis of human parvovirus B19 infection is carried out using a serologically active epitope in the form of a synthetic peptide. The diagnostic method uses antibodies to regions localised in the 'left hand orf' or 'right hand orf' of the B19 virus. The synthetic peptide preferably corresponds to the 'right hand orf' epitope. It comprises at least a five amino acid sequence from a number of specified sequences, including: Phe-Ala-Lys-Ala -Val-Thy-Gln-Gln-Phe -Val-Glu-Phe-Tyr-Glu -Lys-Val-Thr-Gly -Thr-Asp-Leu -Glu-Leu-Ile-Gln -Ile-Leu-Lys-Asp -His-Tyr-Asn-Ile -Ser-Leu-Asp. A vaccine containing one or more of the peptides and a carrier is also claimed. USE/ADVANTAGE - B19 virus causes infection associated with erythema infectiosum. After developing erythema infectiosum (fifth disease), antibodies to B19 are found in the blood. B19 appears to be associated with polyarthritis, aplastic crisis, Schonlein-Henoch purpura, and embryo pathologies and non-immune hydrops foetalis. The antibodies and peptides are therefore useful for the study of the virus infection, for prevention by immunisation and for diagnosis of the disease.

IPC: H03M7/04
Filed: 1990-07-13
Abstract: A method of matching the output of an n bit analogue-to-digital convertor or ADC to the input of a computer involves converting the digital signal which appears at the ADC output in binary code into two's complement form.
