Patent DE-4342133-A1 (DE)
Inventor: GEISENBERGES STEFAN
IPC: F01N1/06
Filed: 1993-12-10
Abstract: According to the prior art, it is known to damp noise emissions by means of "antisound". In exhaust gas systems of internal combustion engines this is mostly implemented by subjecting the exhaust gas stream flowing past in the exhaust gas system with "antisound" emitted by loudspeakers (12). However, arrangements of this type have the disadvantage that the hot exhaust gases flowing past reduce the lifetime of the loudspeakers, or measures of this type for active silencing operate only inadequately. According to the invention, an arrangement is therefore described which avoids the disadvantages arising from the prior art. According to the invention, this is realised in that the exhaust gas pipe (10) opens into one of the two chambers of a double-chamber box (17) and a bass reflex pipe (21) projects into this chamber of the double-chamber box (17). The outstanding cancellation of sound at low loudspeaker power is effected by the cancellation of sound being carried out in the chamber of the box (17) into which the ends of the bass reflex pipe (21) and of the exhaust gas pipe (10) open, and by the beam axis S intersecting the centre line M at a distance A between the two pipes (10, 21) or in the pipe (21), and the length of separation L between partition (18) and centre line M being a maximum of 75% of the greatest diametral extent of the loudspeaker (12). <IMAGE>

The anode is insoluble and dimensionally stable. Both anode and cathode are immersed in a plating solution contained in an electrolytic container. The solution includes (a) ions of the metal to be deposited on the workpiece, (b) an additive substance for controlling physical-mechanical properties of the metal to be deposited, such as brightness, and (c) an electro-chemically reversible redox couple forming oxidizing compounds when contacting the anode. A metal-ion generator is provided, supplying metal parts of the metal to be deposited onto the workpiece; The plating solution is circulated between the container and the ion generator for maintaining a reaction between the oxidizing compounds and the metal parts for forming metal ions. The plating solution is controllably re-circulated into the container so that a low concentration of the oxidizing compounds is present in the plating solution adjacent to the workpiece.

Title: Rake adjustment for vehicle seat with seat depth adjustment
Inventor: BAUER HEINZ
IPC: B60N2/02
Filed: 1994-01-14
Abstract: The seat back is pivoted about a first axis (30) driven by an eccentric adjustment (34) and positioned at the upper end of the linking arm (28). The bottom end of the linking arm is pivotted about a second, parallel axis (32) comprising the second eccentric adjustment.

Filed: 1994-02-08
Abstract: The filter/ppte. contains filters in gps., within a compartment (7). For each filter there is a high tension electrode (13), fed by a high tension constant current source (15), which sets up an electric field in the interspace between it and the filter. Each cylindrical filter (10,11,12) has an earthed carrier electrode on its surface, or within. It is important to place the unit early in the flue gas ductwork, where temps. of 500 deg C. and higher exist. The high tension electrodes are so constructed, located and configured relative to the filters, that an electrostatic field, without corona discharge, is established.

Title: Vehicle with torque distribution system
Inventor: SHIBAHATA YASUJI
IPC: B60K23/04
Filed: 1994-07-07
Abstract: In a vehicle with a torque distribution system a hydraulic motor (24) is connected to a hydraulic pump (20) and drives a planetary transmission (P), which is added to a main differential (D) in order to distribute the torque of an engine (E) to left-hand and right-hand wheels (WL, WR) in a predetermined ratio. A torque corresponding to a cornering state of the vehicle is distributed to the left-hand and right-hand wheels (WL, WR), the speed of the hydraulic motor (24) being controlled by an electronic control unit (U). Should the left-hand or right-hand wheels (WL, WR), to which the torque has been distributed, slip excessively, a torque reduction means reduces the torque of the engine (E) by a command from the electronic control unit (U), in order to suppress the excessive slip. It is thereby possible to prevent a sudden change of the steering characteristics due to excessive slip of the driving wheels (WL, WR). <IMAGE>

IPC: E04B1/19
Filed: 1987-08-22
Abstract: The system described is intended for flat and curved supporting structures comprising hollow-section bars (12, 13) and nodal elements (18, 20) composed of hollow elements which can be assembled in a releasable manner with the hollow-section bars (12, 13) by means of screw fasteners (22, 24, 26) and by which an interconnectable and at least partly closed-off pipe network can be produced, whereby said network can be filled with a fluid or gaseous medium by means of a feed and discharge line. The nodal elements (18, 20) have a cup- or ring-shaped configuration and have, on their external surfaces, working and assembly surfaces (30, 32) intended for sealed assembly with the working and connection parts (34, 36) of the hollow sections (12, 13) or the adjacent nodal elements (18, 20). These surfaces (30, 32) each have at least one through-hole (40, 42) for securing screws which have a through-hole (60, 62), preferably axial, connecting the internal nodal space (50, 52) with the inside (54, 56) of the hollow-section bars (12, 13) assembled with the nodal elements (18, 20). The nodal elements (18, 20) are each provided at least with one aperture (64, 66, 68) which can be closed hermetically by means of a cover (70, 72, 74) which is fixed in a removable manner on the nodal body (18, 20).

Abstract: Une soupape de limitation de pression présentant des coefficients de débit de 3000 litres par minute et plus est caractérisée par un piston à soupape (10) en forme de douille, disposé de manière coulissante dans le sens longitudinal du corps de soupape (2), contre l'effort d'un ressort de soupape (11). La soupape (1) est subidivisée en deux chambres (46, 47). Le piston à soupape (10) constitue avec le piston pilote rapporté (60) une unité de construction, le piston pilote dont le diamètre est inférieur étant chargé par la cuvette de ressort (26) et le ressort de soupape (11). Le ressort de soupape (11) est réglable de sorte que la valeur d'ouverture de la soupape de limitation de pression (1) peut être déterminée d'avance. La configuration particulière du piston à soupape à gradins (10) avec piston pilote (60) permet d'utiliser des cuvettes de ressort (11) ayant des effets de ressort et des dimensions relativement faibles, de façon que la soupape tout entière présente elle aussi des dimensions relativement avantageuses. La réponse de la soupape de limitation de pression est assurée grâce à la conception à gradins du piston à soupape (10)/piston pilote (60) et des bagues d'étanchéité (19, 51) mises en ÷uvre qui se trouvent à l'extérieur sur le piston à soupape (10) à diamètre important, sans entraver sensiblement son mouvement par l'effet de la friction. Malgré cela, l'étanchéité est assurée, car les bagues d'étanchéité (19, 51 et également 75) présentent une grande résistance et une faible friction.

Title: Procede de depot en phase vapeur par bombardement d'electrons a l'aide d'un materiau a plusieurs constituants
Inventor: SCHILLER NICOLAS
IPC: H01J37/304
Filed: 1994-10-11
Abstract: Les procédés de dépôt en phase vapeur de type connu, par application d'un matériau de pulvérisation composé de plusieurs constituants (alliages, mélanges, composés) ne permettent pas d'obtenir des résultats satisfaisants de qualité des couches. Il est très difficile d'obtenir des couches de composition et d'épaisseur constantes. Selon l'invention, le rayonnement X qu'émet le matériau de dépôt au point de rencontre avec le faisceau d'électrons est mesuré in situ. Le signal qui en résulte fait office de grandeur de référence pour réguler la vitesse d'application et la composition de la couche. Le procédé s'utilise dans la production de couches anticorrosion, de couches à haute résistance thermique, de couches anti-usure ou de couches optiques, par ex. sur des feuillards ou sur des films plastiques.
