  • Patent number: 4856551
    Abstract: A double seat valve includes a housing with a pair of valve disks independently movable within the housing between a closed position and an open position. Further, the valve disks can also be moved as a unit. A hollow leakage space is located between the valve disks. Leakage can be conveyed from the space to the exterior of the housing. Each valve disk has a separate valve seat and a cylindrically shaped wall surface extends between the valve seats and defines the radially outer boundary of the leakage space. A seal mounted in the first valve disk contacts the first valve seat in the closed position and moves in sealing contact with the cylindrically shaped wall surface as the first valve disk moves from the closed position toward the open position so that leakage losses from the valve are avoided.

  • Patent number: 4842113
    Abstract: A clutch (3) which can be engaged and released by a controllable clutch drive (11) is arranged in the torque transmission path between an engine (1) and a gear transmission (5) of a motor vehicle. By means of a control switch (15) the clutch (3) is released whereby the vehicle can coast free-wheeling, saving fuel, with the engine (1) working in idling rate. On actuation of a brake pedal (15) a control circuit (13) engages the clutch (3) and at the same time shuts off the fuel supply to the engine (1) by means of a fuel valve (23). The engine (1) thus brakes the vehicle without additional fuel consumption. Alternatively the control circuit (13) can have constantly shut off the fuel supply of the engine (1) in free-wheeling operation. Under control of a pressure detector (45) detecting the suction in a servo-brake unit (41) the control circuit (13) engages the clutch (3) when the pressure rises to values which no longer guarantee operation of the brake unit.

  • Patent number: 4671703
    Abstract: Apparatus for driving an open-ended pipe 7, which has a driving shoe 6 at its leading end, through the ground comprises a driving member 2, 3 to which percussive driving forces are applied by a driving mechanism. Instead of fitting the part 3 of the driving member directly into the rear end of the pipe 7 as is usual an intermediate component 8 is interposed between the pipe and the part 3. The component 8 has soil outlet openings 10 and a deflector 16 to allow soil which enters the pipe 7 through the shoe 6 as driving proceeds to pass through and out of the pipe without stopping the driving. The passage of the soil through the pipe 7 is assisted by water supplied under pressure through a pipe 11 to an annular duct 12 in the shoe 6, when the water flows inwards through nozzles 13 and then rearwards through the pipe 7 carrying the soil with it.

  • Patent number: 4667299
    Abstract: In the disclosed portable computer, a keyboard with keys for entering at least a full alphabet and ten digits is coupled to a computer system that includes a central processing unit which is in turn coupled to a display arrangement with a liquid crystal display. The entire computer is mounted in a case composed of a base and a cover hinged to the base. The base houses the computer system and the keyboard, and exposes the keyboard for operation by a user when the cover is open, while the cover houses the display arrangement and exposes the liquid crystal display on its inner surface. The cover is hinged at the edge of the base and, when closed, covers substantially the entire upper surface of the base.

  • Patent number: 4647174
    Abstract: Disclosed is a method of detecting the focusing condition of an image forming optical system to an object, in which two images of the object are formed with respective light beams from the prescribed exit pupil areas lying in almost symmetry to each other with respect to the optical axis of the optical system and are sensed to obtain an equal number of picture element data for each of the images, and based on the thus-obtained picture element data, while sequential shifting for the first image is carried out from its one end to its opposite end, and a sequential shifting for the second image from its symmetric one end thereto to its opposite end, each by a predetermined number of picture elements, a correlation betweeen the first and second images in every predetermined equal number of picture elements is sought, whereby an optimum correlation is obtained, the corresponding mutual positional relationship between the above-described predetermined numbers of picture elements is detected to discriminate whether

  • Patent number: 4641990
    Abstract: A coupling assembly including a lock latchable in the unlocked position particularly for connecting a universal shaft with a power takeoff shaft in agricultural implements, wherein a coupling sleeve on the universal shaft may be slipped into torque transmitting engagement onto a power takeoff shaft and held in the locked position by locking members engaging within an annular groove of the power takeoff shaft. A lock ring holds the locking members in the locked position and when it is desired to release the coupling, a gripping sleeve is moved so as to disengage the lock ring from the locking members to enable disengagement of the locking members from the annular groove in the power takeoff shaft.

  • Patent number: 4641988
    Abstract: For releasably joining two structural components (1,2), particularly plate-shaped structural components which extend at a right angle relative to one another, a fitting has a preferably cylindrical locking element which can be inserted either directly in a bore (4) in the first structural component (1) or it can be inserted indirectly in a housing, and a holding piece (5) with a holding projection (7) anchored in the second structural component (2). In the assembled position, the holding projection 7 abuts against one or two gripping surfaces (8) of the locking element (3) which gripping surfaces (8) are of, for example, eccentric shape, and the holding projection (7) is pulled toward the locking element when the locking element (3) is turned. The holding piece (5) is constructed plate-shaped and is insertable in a slot (6) in the second structural component (2).

  • Patent number: 4640452
    Abstract: A device for driving nails, staples and similar fastening elements includes an electromotor for rotating a driving member. The rotation of the driving member is transferred to a driven member which, in turn, converts the rotational movement into translational movement. The rotational movement from the driving member to the driven member is effected for a limited time period by a clutch so that a drive stroke and a return stroke are carried out. A releasing device actuates the clutch.

  • Patent number: 4636053
    Abstract: A distance detecting device comprising radiation projecting means for projecting a radiation beam; radiation sensing means which is disposed away from the radiation projecting means with a given length and is arranged to receive a reflected radiation beam coming from an object whose distance is to be detected as the radiation beam is projected from the projecting means; and movable means for relatively varying the incident condition of the projected radiation beam onto the sensing means. The distance to the object is found either by the position of the movable means or by the amount of displacement thereof which occurs at a time point at which the sensing means optimally receive the reflected radiation beam coming from the object in the process of relatively varying the incident condition of the projected radiation beam onto the sensing means.

  • Patent number: 4635572
    Abstract: A process and devices with which the fused sulphur is removed from fossil fuels, preferably coke and petrocoke, ahead of the furnace or the like and is fused with an additive. In the combustion chamber, the additive with the fused sulphur is then sintered. The fuel is desulphurized at a temperature management controllable by an electronic process computer, at controllable residence times and pressure conditions in leading zones so that practically completely desulphurized fuel is burned in the combustion chamber. The sulphur components are removed with the additive via an ash removal plant. A combustion of the sulphur components of the fuel to SO.sub.2 within the combustion chamber does not occur.
