A control device for an automobile has at least one sensor (8) for detecting an operational state of the automobile. An output from the sensor is applied to a sample and hold circuit (11) which is adapted to provide a time displaced output to a hierarchical group of neural elements (13). The neural elements operate upon said time displaced signals by varying the weighting of the signals and/or thr...

In a process for smelting steel from scrap and/or metal-containing, waste-like materials, the continuously or discontinuously introduced metal carriers are preheated and melted in a fixed bed, and oxygen-containing gases are injected via at least one secondary nozzle level in the region of the fixed bed and/or above the fixed bed. The waste gas from the fixed-bed reactor (1) is fed to a thermal re...

Method and composition for vaccination of a pig against swine dysentery caused by T. hyodysenteriae infection characterised by parenteral, preferably intramuscular, administration to the pigs of a live strain or of an oxygen-treated, non-viable strain of T. hyodysenteriae.

The invention relates to a mammographic apparatus (1) making it possible to produce negatives of breasts of medium to large size and/or medium to high density with the aid of a receiver (86) of the intensifying screen/film pair type, without increasing the dose absorbed by the patient or degrading the quality of the negatives compared to the negatives produced for such breasts with the aid of X- r...

The invention relates to a process for the production of substantially non-alcoholic beer by a continuous yeast treatment at a low temperature. In the process, wort which has been clarified and possibly treated by evaporating and/or with an absorbing agent is passed through a packed column reactor containing immobilized yeast at a temperature ranging between the freezing point of wort and +10 DEG ...

A non-contact row crop sensor comprises one or more transmitter/receptor pairs (24, 26; 34, 36) mounted on two row separators (10, 12) of a harvesting machine. Each transmitter (24, 26) transmits an energy beam (40, 42) to one of the receptors (34, 36) and the energy beams (40, 42) cross at a point which defines a position of the harvesting machine relative to a row of crop stalks (18). A circuit...

Date Jun. 28, 1990.A method of photometric in vitro determination of at least one blood gas parameter in a sample of whole blood. The whole blood sample is obtained by connecting an at least partially transparent sample container to an in vivo locality and tran...

Apparatus (10) for checking a bead (1) of adhesive forming a joint (seal), the adhesive being supplied at the end of a nozzle (2), which apparatus comprises a light-emitting source (27), a detection zone (C) located in the vicinity of the nozzle outlet, a light-receiving cell (31) and transmission means (28, 29, 30, 31) connecting the emitting source to the detection zone and the detection zone to...

In order to prevent the risk of the formation of an explosive mixture of escaping blowing gas being liberated with atmospheric oxygen in the production of CFC-free polyurethane foams on use of, for example, pentane, butane or hexane as blowing agent, an inert gas in an amount which prevents an explosive blowing agent/oxygen concentration is added to the chemical system.

A multifunctional method for optical determination of numerous quality-determining parameters of textile surfaces with the aid of an identical arrangement of an imaging sensor and an especially designed illumination device is described. The illumination device consists of a multiplicity of point-like light elements, especially semiconductor light-emitting diodes, which are fixed on a spatially cur...

The invention relates to a pneumatic vehicle tyre consisting of a carcass which is provided with layers made of different rubber compounds, the carcass having in the region of the tread a profile arrangement under which all-round steel and/or textile arrangements, or plastic panels in a sandwich design are arranged in order to reinforce the tread. The carcass also has a bead foot which adjoins the...

A vehicle navigation control system has primary prediction error width calculating means for calculating a primary near-distance error width between a forward extending line of the vehicle and a target path at a predetermined near-distance observing location and for calculating a primary far-distance error width between the forward extending line and the target path at a predetermined far-distance...

The invention relates to a process for producing a hard-metal or ceramic bar which has at least one helical internal hole (16) and a smooth outer surface. The plasticised extrusion compound is forced through a die (2) with a smooth bore (4). Arranged within the die (2) is a twisting device (8). This twisting device (8) imposes a twisting motion on the extrusion compound or, alternatively, a rotati...

A safety ski binding releasably holding a boot on a ski. The binding includes a jaw adapted to hold the boot and to pivot laterally, and an elastic mechanism biasing the jaw against lateral pivoting. When vertical stress acts on the binding, friction is generated which further biases the jaw against lateral pivoting, thereby preventing lateral release of the boot when dangerous lateral stress acts...

Circuit for monitoring a pulse train (P) comprising an input stage (K1) to which are fed the pulses to be monitored, and circuit means in order to determine the presence of a pulse of said train. If in a predeterminable time interval no pulse is observed in the circuit input stage, an output stage of said circuit is activated which provides an output pulse train (BR) and an error signal (ER).
