Title: Injector for fuel-gas mixture - uses base plate of gas jacket body to adjust gas volume before installation of body
Inventor: LINSSEN MATHIAS
IPC: F02M43/04
Filed: 1992-10-29
Abstract: The injector has a gas jacket body (1) consisting of a gas intake channel (7), jacket (8), cover (9), and base (11). Gas passes through the channel into an intermediate chamber (60) between the  jacket and fuel injection valve (5). This permits the gas to flow between base plate and downstream end of the injection valve in radial direction to the passage aperture (13). The proportioner profile for the gas is formed by a gas ring gap (79). The gap is formed by the height of the knobs (77), which extend from the base plate in an axial direction towards the injection valve. USE/ADVANTAGE  - IC engine. Simple and economical gas jacket body.

Title: Method for cleaning a filter device, and filter device for applying the method
IPC: B01D37/02
Filed: 1993-02-19
Abstract: The invention relates to a method for cleaning a filter device for liquids, in particular swimming pool water, in which the liquid to be filtered is drawn off from a container via filter elements having an alluvial filter aid layer and which involves, in the cleaning operation, the filter aid layer being washed off into a transverse channel which has a discharge orifice and is disposed at the lowest point of the container. So as to be able to reliably dispose of the contaminated filter aids it is proposed that, during the cleaning operation, the container first be emptied via the filter elements, applying filtration, apart from a residual amount of liquid and that the filter aid washed off be mechanically discharged from the transverse channel and be delivered to a receptacle.

IPC: B60R21/045
Filed: 1994-07-28
Abstract: A safety device for a vehicle occupant on a vehicle seat contains a knee bar (1) arranged in a fixed position in front of the seat. To prevent the occupant from diving downwards if he/she does not have his/her seat belt on, by slipping off the front edge of the seat cushion (5) as a consequence of having the seat pushed far back, the seat cushion (5) can be moved in the event of a crash forwards counter to spring force (7) by virtue of the kinetic energy of the vehicle occupant and in turn onto the knee bar (1). The spring force is of restricted configuration such that it merely ensures a predetermined longitudinal position of the seat cushion (5) in normal operation but does not achieve the object of non-critical deceleration of the vehicle occupant (Figure 1). <IMAGE>

Inventor: CERVISI RICHARD T
IPC: B64G1/40
Filed: 1994-09-19
Abstract: A reusable satellite system which returns has a return-flight device as well as an acceleration and positioning device. The return-flight device provides the acceleration and orbit insertion and, furthermore, functional services in orbit for carrying the payload, leaving the orbit, reentry (into the earth's atmosphere) and landing on a runway. The acceleration and positioning device is mounted on a carrier aircraft and is fitted with the return-flight device. The carrier aircraft positions the acceleration and positioning device in a desired first position, where the acceleration and positioning device is removed from the carrier aircraft. After this, the acceleration and position device positions the return-flight device in a second position, where the return-flight device can be separated from the acceleration and positioning device. The second position is such that the return-flight device can achieve a desired orbital trajectory.

Title: Systeme de controle fiable de la tension
Inventor: SCHWENKEL HANS DIETER
IPC: G01R19/165
Filed: 1995-12-06
Abstract: Un dispositif de comparaison entre deux tensions continues (U1, U2) comprend un comparateur de tension (3) avec deux entrées (9, 11). Une des deux tensions (U1, U2) à comparer est directement fournie à une des entrées (9, 11). L'autre tension parvient à un convertisseur de tension (2) dans lequel une tension alternative (8) est superposée à la tension à comparer, de sorte que la tension continue générée à la sortie (7) du convertisseur de tension (2) oscille périodiquement à la cadence du signal rectangulaire (8) entre une valeur d'amplitude supérieure et une valeur inférieure. L'écart entre les deux valeurs d'amplitude correspond à la bande de tolérance dans laquelle les deux tensions (U1, U2) à comparer doivent être identiques. Le signal de tension généré par le circuit convertisseur de tension (2) parvient à l'autre entrée (9) du comparateur de tension (3). Celui ne génère un signal alternatif à sa sortie (15) que lorsque la valeur d'amplitude supérieure est supérieure et la valeur d'amplitude inférieure est inférieure au signal continu fourni à l'autre entrée (11) du comparateur (3). Le signal alternatif généré par le comparateur (3) parvient à un transformateur de tension (4) qui le transforme en une tension étrangère au système.
