Title: Contra flow belt dryer esp. for grass and similar crops
Inventor: EYERLE ANTON
IPC: F26B1/00
Filed: 1993-01-26
Abstract: In a new appts. for drying crops, two endless perforated zigzag belts (1,2) convey the crop (8) in the form a continuous layer through a number of superimposed levels from an inlet (9) to an outlet (11). Axial fans (13) located in the central region of the apparatus supply the drying air to different air inlet zones (14,15,16). Heated air is supplied to the inlet side of at least one of these fans. The air is delivered in contraflow perpendicularly through the crop material. At the inlet to the dryer, the crop material passes between a stationary piercing plate and a guide plate which moves up and down on rails and is fitted with a lance carrier. The lances attached to this lance carrier extend through openings in the piercing plate and penetrate the crop material. During the upstroke, the lances are withdrawn fully into the guide plate, and the stroke of the guide plate is less than that of the lances.

Title: Brick grouping - has assembly of three conveyors with barrier and separator, to form gps. of different lengths for jigging machine
Inventor: KAMPHUES HERMANN DIPL ING
IPC: B65G47/29
Filed: 1993-02-25
Abstract: To form groups of blank bricks for a jigging machine in the brick finishing assembly, with groups of different lengths, the blanks are carried in a continuous stream by a conveyor (2) for transfer to a second conveyor (3) which operates at a speed to match the first conveyor (3) and a following conveyor (4). The bricks travel at the same speed as to first conveyor towards a barrier (7) which is shifted between a block and a release setting, for the bricks to be arranged together in rows without gaps. As soon as the first brick in the row reaches the build-up point, the following bricks form a group to be separated for removal. During sepn., or at the end, the barrier (7) is withdrawn for the separated group of bricks to be carried off by the third conveyor (4) at a faster speed than the first conveyor (2). At the same time as the gp. is carried off, the second conveyor (3) speed is set to the speed of the third conveyor (3) to take over the sepn. function, while the separator moves the brick blanks towards the barrier (7) at the same speed as the first conveyor (2). As soon as the sepd. gps. have left the second conveyor (3), its speed is altered to the speed of the first conveyor (2) and the line of bricks is advanced toward the barrier (7), with simultaneous movement of the separator to the point where the next group is to be separated. Also claimed is an assembly with three conveyors (2, 3, 4) to carry the bricks through the selections. The separator pref. has height adjustment to act on the end of a group of bricks, esp. the end towards the build-up point at the barrier. Each sepd. gp. of bricks is carried to a jigging machine by a conveyor (6) at right angles to the separating conveyors (2, 3, 4). The group half-lengths are aligned to cover the symmetrical plane/axis (S) of the conveyor (6) to the jigging machine. USE/ADVANTAGE - The operation is for the provision of groups of bricks of different lengths for a jigging machine with a continuous action to give high capacity.

Title: Window wiper arrangement with wiper arm which is linearly driven by means of a cable drum
Inventor: EGNER-WALTER BRUNO
IPC: B60S1/20
Filed: 1993-03-13
Abstract: The invention relates to a window wiper arrangement with linearly guided wiper arm which is driven via a boden cable. In order to guide the wiper lever (3) in a simpler way, the latter is driven by means of boden cable (8). In order to increase the drive force and to simplify the guidance of the wiper lever (3), the boden cable is driven by means of a looped boden cable which engages on a cable drum. The cable drum can create an oscillating rotational movement in that an oscillating articulated rod engages on the drum by means of a toothed gearing or in that a second looped cable acts on the cable drum. The second looped cable can be formed by a cable (25) whose ends are attached to the articulated rod (16). <IMAGE>

Title: Hydraulic control valve
Inventor: STRIEKER NORBERT
IPC: F15B13/04
Filed: 1993-03-13
Abstract: The present invention relates to a hydraulic control valve for lifting, for example, the cutting mechanism of a self-propelled combine harvester, in which the full pressure-oil volume does not act abruptly but smoothly on the lifting cylinder. For this purpose, the control valve is provided with two annular spaces for the discharge of the pressure oil and with a control spool provided with two control edges, the annular inflow space lying centrally between the annular spaces. At the start of the lifting action and if need be at the end, the lifting magnet is loaded with only 6 volts, as a result of which the pressure oil flows with a small volume through choke pockets. In the process, the axial components of the impulse forces assist the action of the closing spring. As soon as the lifting magnet is loaded with 12 volts, the pressure oil flows with a large volume through the second annular space. In this case, the axial force components of the impulse forces act in such a way that they assist the force of the lifting magnet, since the peripheral surface adjoining the corresponding control edge is of curved design.

Title: Process for purifying glycerol water
Inventor: BLUM STEPHAN
IPC: C02F1/44
Filed: 1993-07-31
Abstract: The glycerol water (sweet water) arising in the high-pressure splitting of natural fats and oils into fatty acid and glycerol using steam is continuously purified. Solids having diameters above 100  mu m are separated off from the aqueous phase by means of a plate phase separator and these are returned to the high-pressure splitting. The aqueous phase thus prepurified is passed in transverse flow across a filtration membrane, in particular a microfiltration membrane, and the concentrate is returned to the inlet of the plate phase separator. The permeate flows through a fixed bed packed with an adsorber resin. In a particularly economical manner, large product volume streams of glycerol water with frequent change of origin can be continuously and effectively purified.

Patent DE-4424775-A1 (DE)
Inventor: SOBOTTKA RICHARD
IPC: C08J3/22
Filed: 1994-07-05
Abstract: An anti-blocking agent comprising silica or mixtures of silica and zeolite is described, which is characterized in that it has a bimodal pore size distribution, the first maximum of the bidomal pore size distribution being in the pore size range < 5 nm and the second maximum of the bimodal pore size distribution in the pore size range > 6 nm. The anti-blocking agent is obtainable by micronizing a mixture comprising silica of a certain pore size and silica and/or zeolite having a different pore size. It can be produced together with slip agent as a combined anti-blocking and slip agent. Incorporation of the anti-blocking agent or of the combined anti-blocking and slip agent into a polymer in the form of a master batch is preferable. In addition to a better dispersion and distribution of the anti-blocking agent particles in films and the improved optical properties associated therewith, the particular advantage of the anti-blocking agent according to the invention is that the adsorption of slip agent is avoided or greatly reduced, so that less slip agent can be used than in the prior art.

Title: Pressure registering device
Inventor: TSUDA HIROSHI
IPC: B60C23/04
Filed: 1994-07-19
Abstract: A pressure registering device is disclosed for registering the air pressure in a vehicle tyre. In a cylindrical housing, which is fastened axially in parallel alignment with a wheel tyre, provision is made for a setting magnet, a rotor magnet and a reversed magnet in coaxial arrangement, the rotor magnet being rotatable by means of a shaft and being supported so as to be axially displaceable in response to a tyre air pressure which is fed to a bellows located in the housing. If the air pressure is normal, the rotor magnet is attracted by the setting magnet. If the air pressure falls, the rotor magnet is released as a result of the movement of the bellows, is rotated by the repulsion force of the reversed magnet and is finally attracted by the reversed magnet. As a result of this process, the position of the magnetic poles of the rotor magnet is reversed, this reversal being registered electrically by means of a magnetic field registering unit.
