Title: Agricultural appliance for the metered discharge of liquids
Inventor: OBERHEIDE FRIEDRICH
IPC: B05B12/00
Filed: 1983-09-07
Granted: 1984-02-16
Abstract: Agricultural appliance for the metered discharge of liquids, especially of liquid plant treatment agents and fertilisers or the like, consisting of a feed line connected to a pump driven by the take-off shaft of a traction vehicle, of a discharge line following the feed line and of a return line which likewise follows the feed line and is connected to the supply container and in which is arranged a pressure-control valve having a valve tappet which is displaceable and which can be fixed by means of an adjusting element in a position opening any desired throughflow cross-section, the valve tappet being held in position in the state of rest by a prestressed spring. To simplify the pressure-control valve substantially in terms of constructive design, the valve tappet (8) has a guide pin (10) which is mounted so as to be displaceable relative to the adjusting element (11) as a result of the compression of the spring (17), and the guide pin (10) has a bearing element (19) cooperating with the adjusting element (11). <IMAGE>
Patent DE-3347517-C1 (DE)
Title: Device for controlling the quantity of fuel to be fed by injection pumps to the cylinders of a supercharged internal combustion engine
Inventor: HAEFNER REINHARD DIPL-ING
IPC: F02D1/14
Filed: 1983-12-30
Granted: 1984-11-08
Abstract: As part of a device for controlling the quantity of fuel to be fed by injection pumps to the cylinders of a supercharged internal combustion engine, especially one installed in a ship, a governor is provided, which processes the pneumatic reference values and acts on a charging linkage, to which the control rods of the injection pumps are connected for rotation of the pump pistons provided with bevelled control edges. The governor functions on the basis of an engine speed reference value fed into it and a charging-reference-value control variable. The latter is produced in a charging-reference-value transducer, which comprises means for a charging-reference-value default, as a function of the charge air pressure, and a charging-reference-value limit device. The latter serves to limit the charge to a level lower than the maximum charge in those instances in which operation of the engine with a higher charge would be harmful due to exceeding of or failure to attain admissible engine operating values. In addition, a starting pressure simulator is provided which from starting of the engine up to idling speed delivers compressed air to the governor at a pressure for a corresponding charge default simulating the presence of a certain charge air pressure, with the aim of preventing the governor from being able to operate the charging linkage from starting of the engine up to the position corresponding to the maximum charge.
Patent DE-3523760-C1 (DE)
Inventor: SCHMITT ROLF DIPL-ING
IPC: G01P5/01
Filed: 1985-07-03
Granted: 1990-06-21
Abstract: An apparatus for measuring the flow rate of fluid media has a rod-like interfering body rigidly arranged in the flow and which has a cylindrical flow-against surface on which periodically separating eddies form, as well as a device with a sensor for recording the eddy separating frequency which is dependent on the flow rate. In order to obtain a proportional dependence between the flow and separating frequency over a wide Reynolds number range in the case of a low inherent flow resistance, the interfering body is symmetrically bent downstream and to either side from its top. To avoid interactions between the two vortex paths which form, a diverting surface is positioned behind the interfering body in the plane thereof.

Title: Method and device for monitoring and for reworking the cable groove lining of a friction pulley for a cable car
Inventor: LUBOS WALTER DIPL-ING
IPC: B61B12/02
Filed: 1985-08-03
Granted: 1986-12-11
Abstract: In order to process friction pulley cable grooves it is known to use groove cutters which can be swivelled in manually from a stand-by position into the cable grooves. The depth of the engagement can be limited by limit stops. However, measures are necessary for monitoring the wear and personnel are necessary to carry out the recutting. The automatic recutting device 6 according to the invention engages with a sensing element 13 in the incoming cable groove 3 so that the adjacent cable grooves 4, 5 are correspondingly recut as a function of the position of the sensing element 13. An independent further sensing element also engages in the outgoing cable groove 5 which has already been recut and influences the cutter engaging in the incoming cable groove 3. The sensing elements 13 and cutters 15, 16 are permanently loaded in a resilient and elastic fashion in the direction of the axis 2 of the friction pulley. The sensing element 13 can be spring-loaded in relation to the cutters 15, 16 in order to permit the engagement of the cutters 15, 16 independently of the position of the sensing element 13 for the purpose of correcting eccentricities. Electronic sensors with cutters which are at least indirectly influenced thereby are also conceivable. <IMAGE>

Abstract: A process is disclosed for generating a sharp output correcting variable at the output of a fuzzy control circuit constituted by a processor (1), measurement value sensors (2), an inference machine (3), a defuzzer (4) for generating sharp correcting variables and a controlling element (5). According to this process, the fuzzy inference machine (3) supplies a fuzzy amount of possible correcting variables for each control, the correcting variables being delimited upwards by the degree of conformity with the corresponding control. In order to generate a sharp output correcting variable in the defuzzer with as little as possible calculations and hardware, the degree of conformity for each possible correcting variable in the various fuzzy amounts is determined step by step over the whole range of correcting variable, beginning with the minimum or maximum correcting variable. The correcting variable of which the degree of conformity in the control-relevant fuzzy amount reaches for the first time its maximum is selected and transmitted as sharp correcting variable.

Title: Hydraulic cylinder powered drive position indicator
Inventor: MARIAN ALFRED DIETER
IPC: F15B11/12
Filed: 1994-08-16
Granted: 1995-12-21
Abstract: A bypass line (13) between feed and return lines (2,3) contains a valve (14) to free the line when the swivel drive etc. (1) reaches end points. The valve (14) is triggered by the drive piston with the valve arranged in the drive cylinder cover which also contains a screw to adjust the end settings of the drive piston. Details includes a nonreturn valve (4) in lines (2,3) controlled by the pressure in the respective other line and the control valve (7) impresses supply line (8) pressure on one or other line (2,3), assisted by hydraulic valve (10) linked to the metering device and the position indicator. The bypass line is thus freed by valve (14) so as to break down the line pressure (1) and pass this over to line (3). This relieves the feed line (2) of pressure on approaching end point. The nonreturn valve (19) and choke (2) in the bypass smooth out volume transfer when freeing the line (2).

Filed: 1996-06-21
Granted: 1997-12-23
Abstract: The driving and driven members of the press are coupled by a rod in two parts hinging together. A holder keeps the hinge point between the halves at a minimum distance from the line along which the driving force acts. The force exerted by the holder is adjustable, there being typically a ram coupled between the rod halves. The pressure in the ram provides the force, being adjustable by a reducing valve. There can be a detector for the kinking movement, this being coupled to a control unit for the valve on the ram. The latter can be operated by compressed-air, the valve being a quick air-discharge valve.

Title: Windmill for electrical generation has control system which maintains rotation speed approximately constant over wide range of wind speeds
Inventor: TIMMERMANS CORNELIS MARIA
IPC: F03D3/00
Filed: 1998-07-20
Granted: 2000-01-24
Abstract: The rotor is mounted on the top of a vertical drive shaft (A). Each turbine blade (B) on the rotor has a number of channels which slope upwards from the hub. The channels contain a heavy liquid. As the rotation speed increases the liquid is forced outward by centrifugal force and acts to slow the rotation. If the wind speed drops, the liquid flows back, making the rotor easier to turn. At very high wind speeds, a cylindrical shield (D) rises to cover part of the rotor.
