Patent DE-4400114-A1 (DE)
Title: Electrical connector for pneumatic control valve
Inventor: HAUSLER RICK
IPC: F16K27/00
Filed: 1994-01-04
Abstract: The electrical contact construction includes an electrically insulated valve body for a stacked-composite arrangement for a fluid control valve. The valve body has rod-type standard contact pins (11, 12) which pass through the arrangement.The contact pins are inserted in correspondingly formed inputs, which form a single unit with the valve body. This arrangement separates the contact pins both mechanically and electrically from the pneumatic fluid.

Title: Cooling gas ducting mechanism in a piston compressor
Inventor: FUJII TOSHIRO
IPC: F04B27/08
Filed: 1994-02-09
Abstract: The present invention discloses a cooling gas suction valve mechanism for a compressor with reciprocating pistons. The mechanism has a drive shaft which is mounted rotatably in a gas holding chamber which is fed with uncompressed gas, twin-head pistons which are provided in cylindrical bores and compress the gas when the pistons move from bottom dead-centre (outer dead-centre) to top dead-centre (inner dead-centre). An intake connection permits or interrupts, as required, a connection between the intake port and the compression chambers. An elastic (resilient) component keeps a turning valve in contact with an inner wall of a recessed chamber, with a predetermined force. The intake connection is held at a predetermined distance from a point where the pistons reach the top dead-centre, so that the intake connection has already been closed by the pistons before the pistons reach top dead-centre.

Patent DE-4420088-A1 (DE)
Inventor: HOUBEN JOCHEN DR
IPC: A01G31/00
Filed: 1994-06-09
Abstract: The invention concerns a process for producing water-absorbing flat articles made from a water-absorbing polymer and a prefabricated fibre wool. The prefabricated fibre wool is impregnated with a solution containing partially neutralised acrylic acid and at least one cross-linking agent before being pressed to a specified coating volume, the monomer solution which has thus been applied to the fibre wool carrier then being polymerised. The proposed process is characterised by the fact that the polymerisation is carried out in the presence of radical initiators which can be non-heat activated as well as at least one heat-activated radical forming agent. By using a heat-activated radical forming agent as well in the polymerisation process, products can be obtained with a low residual monomer content, better water absorbtion under pressure and higher retention, while at the same time making it possible to use a technically simple and economic manufacturing method. The heat-activated initiator component can be added to the monomer solution or applied to the carrier in quantities of between 0.01 and 0.5 mol % in relation to the monomer which is to be polymerised.

Patent DE-4427222-A1 (DE)
Inventor: SCHMID ACHIM
IPC: F23R3/28
Filed: 1994-08-01
Abstract: A thermal shield (6) for the head area of a combustion chamber has as usual a through-hole (5) for the burner. A continuous collar (14) with air passage holes (16) projects from the back side of the thermal shield at the edge of said through-hole. Cooling air can flow through said holes into a ring-shaped channel (15) arranged between the thermal shield and the burner, then into the combustion chamber. This cool air flow lies as a cool air film on the surface of the thermal shield. For that purpose, the cool air flow or cool air film whirls in the same direction as the combustion air supplied through the burner. To generate this whirling motion, the air passage holes in the collar are inclined in the radial direction. The thermal shield is further provided with appropriate inclined effusion holes (19).

Patent DE-4430906-A1 (DE)
Title: Built=up camshaft e.g. for IC engine
Inventor: REIPERT PETER DR
IPC: B21K1/12
Filed: 1994-08-31
Abstract: The joins between shaft (1) and cams (2) form single-shell rotation hyperboloids. Thus until joined, the join surfaces (3) of the cam holes (4) in the centre plane at right angles to the hole axis are over-dimensioned by 0.020-0.050 mm and are over-dimensioned by 0.015-0.040 mm at the edges, assuming that the joining pressure necessarily increases with the excessive dimension of the cam hole diameter. The shaft is made from seamless cold-drawn or cold-rolled precision steel tube and the outermost radial casing of the strip or spheroidal-graphite (SG) cast-iron cams has a ledeburite matrix. Thus when pressed from steel St52-3 cold-drawn tube and SG cast-iron cams with their ledeburite casing matrix, the diameter of the cam hole join face (3, 4) is slightly less than the cylinder join face of the shaft (1), involving elastic deformation only in the shaft during the joining operation.

Title: Stepper drive for 3-position electric switch
Inventor: WERNER PETER
IPC: H01H3/30
Filed: 1994-09-02
Abstract: The stepper drive uses a spiral wound flexure spring (6) with radial end sections (7,8) acted on by a manually operated tensioning lever (10). The stored spring energy is transferred to a drive lever (11) mounted on a stepping shaft (2), with a cooperating ratchet defining the switch positions. The tensioning lever is blocked during the spring tensioning by an automatic latch mechanism (40,41) when the fully tensioned spring position is reached. Respective latches and counter-bearings (54,55) are  provided for tensioning the spring for each rotation direction of the stepping shaft. The latches are spring-biased into a rest position, and one or the other is released via the manual operating lever (35) for the tensioning lever.

Title: Starting method for electronically commutated DC motor e.g. for driving high speed fan
Inventor: BAUMANN ROLF
IPC: H02P6/22
Filed: 1994-10-28
Abstract: The method involves switching a switching transistor (31,32) associated with a winding (1,2) on and off to start current flowing in the winding of the motor (3), which has electromagnetic asymmetry. To start the motor turning in a defined direction, a first switching transistor (31) is subjected to a first starting pulse tapped from the voltages induced in the windings. Switching pulses subsequent to the starting pulse are generated if the voltages induced in the windings exceed a threshold. If the threshold is not reached, no subsequent pulses are generated and a certain pause is maintained, following which a second switching transistor (32) associated with the second winding (2) is subjected to a second start pulse.

Une partie des micro-organismes qui quittent la trajectoire de mise en contact (1) après s'être développés au mieux dans l'eau chargée sont ramenés dans cette trajectoire de mise en contact (6), ce qui permet d'avoir toujours à disposition les micro-organismes qui sont le mieux adaptés à l'eau à purifier et de disposer également de quantités suffisantes de ces micro-organismes sains. On prélève en outre, loin de la trajectoire de mise en contact (1), une petite quantité d'eaux usées servant d'indicateur, que l'on introduit dans la région où les micro-organismes sont cultivés (17); on constitue ainsi un système de prédétection qui permet de préparer à temps le développement des micro-organismes. Grâce à ce procédé et au dispositif pour sa mise en oeuvre, on obtient un degré de purification uniforme. On peut en outre faire varier plusieurs facteurs de modification, séparément ou collectivement, en fonction des conditions changeantes: l'apport en éléments nutritionnels peut en effet être modulé, les micro-organismes sont adaptés au mieux aux conditions et très variés, et l'apport d'oxygène, autrement dit l'efficacité de l'aération, est réglable.
