Abstract: A method and a device for pneumatically conveying material to be conveyed in a pipe-like conveyor conduit (10), into which compressed gas is introduced from a connection conduit (12, 12a), are improved in that, when there is a rise in pressure in the conveyor conduit (10) in conveying direction (x) upstream of the connection conduit or its opening (13), the latter is opened for air supply from a secondary conduit (16) with high pressure, and in that this air supply into the conveyor conduit (10) is interrupted upon pressure compensation in the conveyor conduit (10) in the areas upstream as well as downstream of the opening (13) of the connection conduit (12). To this end, the connection conduit (12) is provided with a slide (gate) (24) as control member which blocks the conduit in a basic position and is arranged in a flow area (22) between a first and a second sensor conduit (46, 47), each of which opens into the conveyor conduit (10) on another side of the connection conduit (12) and is connected via a constriction length (40, 41) to that section (12e) of the connection conduit (12) leading to the secondary conduit (16). Specially designed valves (50, 52) are provided in the connection and sensor conduits (12 and 46, 47). <IMAGE>

Title: Laminated stator core for an electric motor, and a method for producing a stator
Inventor: FUETTERER BODO
IPC: H02K15/02
Filed: 1989-03-08
Abstract: In the case of known electric motors, in which the stator is composed of laminated cores, difficulties with the fitting of the stator windings result, particularly when the axial lengths are large. In the case of the method, stator laminates are stamped out, in which the lateral ends of the pole shoes are connected to one another via connecting webs (12). The outer edge (10) of the stator laminates is cut off during stamping. After the winding of the webs (11) which form the poles (5), the edges (10) are pushed onto the wound laminated stator core (9), in the form of a sleeve (13). The invention is used in the production of electric motors. <IMAGE>

Patent DE-3932361-A1 (DE)
Inventor: OSHITA SAIICHIRO
IPC: B62D7/15
Filed: 1989-09-28
Abstract: A steering control method for vehicles with four-wheel steering, characterized by detection of either the steering force, the lateral force or the lateral slip force of the front-wheels and the rear-wheels. The detected forces of the front-wheels and the rear-wheels are assumed to be proportional to the respective lateral slip angles. The front-wheel steering angle is then controlled by calculating and adding to the front-wheel steering angle a compensation steering angle proportional to the front-wheel lateral slip angle. The rear-wheel steering angle is then controlled to be proportional to the rear-wheel lateral slip angle. This control method allows the front and rear steering coefficients to be variably and independently controlled, e.g. to provide improved vehicle behaviour when the steering input is abrupt. <IMAGE>

A fluid P sulphide (I) melt contg. over 28.2% P is produced in a first stage in a small reactor and converted to (I) by adding S in a second stage. The novel features are that in the first stage, the reactants are introduced into the vapour phase above the liq. level, so that vapour forms at the surface of the boiling liq. and (I) contg. at least 50% P4S3 forms in the vapour phase, the (I) vapour is condensed in the condenser and introduced into the (I) melt, the second stage is in 2 separate reactors, one charged with up to 50% of the total amt. as fluid (I) melt from the condensation zone of the first stage and with S, giving (I) of high purity and a max. P content of 52% and the other reaction is charged with the rest of the (I) melt as sump prod. and reacted with S giving (IA) of technical purity. ADVANTAGE - The process is more economical than usual and gives (IA) of technical purity and pure (IB) e.g. P4S9 or P4S7. The same plant is used for making both prods. and the plant capacity is high
