Title: Electro-hydraulic control device
Inventor: HONIG ERNST-AUGUST DIPL ING
IPC: F16H61/06
Filed: 1986-05-28
Abstract: An electro-hydraulic control device for the automatic shifting of the gears of a hydrodynamic-mechanical motor-vehicle transmission, containing a multigear planetary gear train, has shift members, actuable by pressure medium and assigned to the individual transmission gears, of which members at least one can be disengaged and another engaged when shifting up from a lower into a higher gear. In order to achieve an optimum, smooth gear shift when changing gears, it is proposed that a control valve (1) be provided in an actuating line (23) leading to the shift member (24) to be disengaged in the respective gear change, which valve connects the actuating line either to a pressure medium line (21) delivering the actuating pressure or to an outlet line (27), as a function of a pressure building up upstream of the shift member to be engaged and of a pressure which can be controlled by a solenoid valve (15) as a function of the operating state. <IMAGE>

Title: Hydraulic dual-circuit brake system for motor vehicles
Inventor: REINARTZ HANS-DIETER
IPC: B60T13/14
Filed: 1986-11-25
Abstract: For monitoring the failure of a brake circuit of a dual-circuit brake system for motor vehicles, in which a tandem brake master cylinder (1) can be actuated by a brake booster (2) fed from a hydraulic energy supply system (3) and control valves (32 to 35) of a brake slip control device are provided in the brake lines (28, 30) of both brake circuits, a differential pressure switch (49) is connected between the two brake lines (28, 30), which in the event of a fall of the pressure in one brake line (28 or 30) is switched by the pressure in the other brake line (30 or 28) and thereby produces a closure of the control valves (32, 33 or 34, 35), which connect the brake line (28 or 30) in which the pressure has fallen to a group of wheel brake cylinders (Fig. 1). <IMAGE>
Patent DE-3643279-A1 (DE)
Title: Jigsaw with push-rod stroke movement generated by a Scotch-yoke mechanism
Inventor: FUCHS MICHAEL ING GRAD
IPC: B23D51/02
Filed: 1986-12-18
Abstract: To change the push-rod stroke in jigsaws by changing the direction of rotation, it has already been proposed to arrange a plate pivotably on the driving toothed wheel, the axis of which plate lies eccentrically with respect to the axis of the driving toothed wheel and which contains an eccentric pin engaging in a connecting link attached to the push-rod. In this arrangement, the plate has two stop faces, one of which comes to bear on a stop attached to the driving toothed wheel on dextrorotation of the driving toothed wheel and the other of which comes to bear on a stop attached to the driving toothed wheel on laevorotation of said toothed wheel. To impart to the push-rod in a simple way a movement transversely to its longitudinal movement (pendulum-stroke movement), the plate (11) serves at the same time as drive for a stroke element (21), the stroke movement of which can be converted by means of a deflecting device (24, 25) into a periodic transverse movement of the push-rod (14) (Fig. 1). A jigsaw of this type makes possible pendulum-stroke operation both in the case of a short length of stroke of the push-rod and in the case of a long length of stroke thereof, since the pendulum stroke changes automatically and in the same direction with the changeover of the push-rod to the one or other length of stroke. <IMAGE>

Title: Terry fabric, process for producing it and weaving machine for carrying out the process
Inventor: RITTER FRITZ
IPC: D03D27/08
Filed: 1987-03-06
Abstract: In a terry fabric, especially for blankets and cloths, with pile threads (3, 4) forming loops on only one side of the fabric, between any two loops succeeding one another in the warp direction the pile thread (3, 4) forming these loops bears stretched on the basic fabric in a floating manner over at least two weft threads (2). In order to achieve this bearing contact, during the beating-up of each weft group the tension of those pile threads which have to form a portion bearing in a floating manner against the basic fabric is increased to a value which prevents loop formation. For this purpose, the weaving machine has a warp beam for each group of pile threads and a separate tension device for each of these groups. <IMAGE>

Title: Hydraulic facility
Inventor: OGAWA KENJI
IPC: F04B7/04
Filed: 1987-03-26
Abstract: The invention concerns hydraulic facilities, in particular continuously operating hydraulic facilities which are intended to deliver a constant amount of fluid continuously as a hydraulic pump, or in which precise drive control for pumping very small amounts of fluid is desired. The invention is intended to improve such hydraulic facilities, in particular by achieving a precise relationship between the fluid pumping behaviour of a hydraulic set and an associated rotary drive unit; the hydraulic facility is to operate both in a pumping mode and in a motor mode. In the invention, the hydraulic facility is provided with one or more hydraulic devices (95) containing a pair of pistons that can be operated by way of a rotating cam control device (60), or which drive the latter by means of a pump drive. To maintain an output volume constant when the hydraulic facility is operated in the pumping mode, preferably four pumping devices (95) are provided in the framework of an attachment block (20) of the hydraulic facility; these can be driven out-of-phase by the rotating cam device (60). The invention can be used in the construction of fluid-controlled machinery, in particular for precision fluid-pumping devices (Fig. 1). <IMAGE>

Title: Process for carrying out ion exchange reactions on micas
Inventor: KEPPLER HANS
IPC: C09C1/40
Filed: 1987-08-22
Abstract: Technical problem: ion exchange reactions on micas could hitherto not be carried out on an industrial scale; the known methods require either very long reaction times of several weeks or lead to partial decomposition of the mica. The new process allows an ion exchange on micas within short reaction times and avoids the formation of decomposition products. Solution: to carry out the ion exchange, micas are treated with salt melts at temperatures of up to 950@C over a time period of several hours. The formation of decomposition products is prevented by exclusion of air, moisture and alkaline substances. Fields of application: recovery of rubidium and caesium from natural micas, incorporation of highly radioactive and toxic elements in mica for the purpose of ultimate storage, incorporation of <137>Cs in mica for safe handling as gamma-ray source, production of new types of mica in particular as components of corrosion protection paints.

Title: Apparatus for conditioning room air
Inventor: VAHLBRAUK KARL HEINZ
IPC: E04C2/52
Filed: 1987-08-28
Abstract: Many forms of panel-type heating elements, in the case of which a material suitable for storing heat is heated by a heat-transfer medium, are known. However, by means of these heating elements, which can also be used, in principle, as cooling elements, it is only possible to control the temperature, and not the humidity, of the respective room air. In order to condition room air, namely to control the temperature and humidity, the invention proposes an apparatus which comprises two panel-type structural parts (1, 6), of which one (1) serves to receive steel pipes (2), in which a heat-transfer medium flows, and bores (8) are arranged in the other in order to receive evaporated water. The basic material of the two structural parts (1) and (6) comprises the components loam and cement, which is fired at temperatures of approximately 500@C, with the result that a high-capillary material which can store heat is obtained. A heat exchange and mass transfer with the surrounding room air takes place via the outer surface of the apparatus, formed by the structural parts (1) and (6), as well as the cited capillary system. <IMAGE>

Title: Screw-connection for connecting two components which are located at a distance from one another
Inventor: DIETZE ROLAND DIPL ING
IPC: F16B5/02
Filed: 1988-07-25
Abstract: The invention relates to a screw-connection (1) for connecting two components (2, 3) which are located at a distance (4) from one another. In a series of application cases, bracing between the components (2, 3) is not to occur when fitting the screw-connection (1). For this purpose, the invention makes provision for threads (7, 8) of different diameters to be provided on the two components. Correspondingly, the screw-bolt (9) also has a front thread region (11) of a smaller diameter and a rear thread region (12) of a greater diameter. All the threads have the same pitch. The front thread region (11) is configured to be so long that, when set and partially screwed into its corresponding threaded bore (8), the screw-bolt (9) still does not come into contact with one component (2). A necessary compressive force for a screwing device is absorbed by the component (3), and the component (2) is not, as in the case of other screw-connections, forced in the direction of the component (3) here. When the screw-bolt (9) is screwed further in, the rear thread region (12) grips in the component (2), as a result of which the latter is held in a stress-free manner. <IMAGE>

Filed: 1988-08-11
Abstract: A support vehicle in the form of a tractor (16) carries a main fixed frame (8) on which is arranged an intermediate frame (7) the height of which can be adjusted by means of a cylinder (10). The intermediate frame supports, by means of two hydraulic cylinders (121) symmetrical about their common articulation (13), a support beam (5) on which are arranged, near each end, sensing devices (26) each with two staggered sensing contacts (21-24). Also arranged on the support beam (5) is a spraying device (6) with a row of spray nozzles (9) which spray a treatment fluid. Each pair of sensing contacts, (e.g. 23, 24, 211, 212), detects the height (c) of the support beam (5), and hence of the spray nozzles (9), above the ground (1) or envelope surface (4) of the crops (3). The measurement current, which flows through the plants and enters the ground, is drawn from the battery (18) of the vehicle, the negative terminal of which is earthed and the positive terminal of which is connected via the control unit (32) to the sensing contacts, which are connected by earth current circuits to the tyres (19). The more accurately the distance (b) above the crops (3) is maintained, the more uniform and hence the more efficient are the spraying operations.

Patent DE-3833830-A1 (DE)
Inventor: BOCHMANN KLAUS
IPC: B02C19/06
Filed: 1988-10-05
Abstract: Fluidized-bed counter-jet mills are gas-jet mills with which extremely fine milling results can be produced with very little wear and tear. An improvement in the milling results can be achieved by cooling the gas jets with a refrigerant, but the improvement that can be achieved is not substantial and the consumption of refrigerant is very high. In order to lower the consumption of refrigerant while considerably improving the fineness of the milled material, the coarse material which is separated by the grader of the mill is cooled by the refrigerant within the fluidized-bed counter-jet mill and fed back into the milling chamber. Liquid nitrogen is the preferred refrigerant with which the sump of the mill is cooled.
