  • Patent number: 4626146
    Abstract: A tool holder for securing a drilling or chiseling tool in a device includes a guide tube for receiving the cylindrically shaped shank of the tool. An adjusting sleeve laterally encloses the guide tube and the sleeve is axially and rotatably displaceable relative to the guide tube. When the adjusting sleeve is axially displaced a cam projecting from one of the adjusting sleeves and the guide tube contacts a cam surface on the other for effecting the rotational displacement. The cam surface is inclined relative to the axial direction of the guide tube. Openings extend through the guide tube between its inner and outer surfaces and recesses in the inside surface of the sleeve register with the openings when the sleeve is rotatably displaced. Locking elements are radially displaceably mounted in the openings in the guide tube and secure the tool shank in the holder.

  • Patent number: 4626182
    Abstract: An external shaft rotary piston machine wherein pistons of a piston rotor run in engagement with a cavity of a circular cylindrical sealing rotor during a particular relative rotational position of the rotors, the cavity being substantially larger than necessary for passage of the pistons in order to avoid flow losses due to seal wedging flow and compression. In order to avoid overflow from the high pressure side to the low pressure side of the machine through the sealing rotor while the pistons move in the sealing rotor through the space defined by the cavity, a sealing effect is created by a leading edge and a trailing edge portion of the opening of the cavity of the sealing rotor moving along a leading and a trailing side surface of the pistons. This is effected kinematically due to the fact that the trailing edge of the cavity opening is displaced radially inwardly and that an edge portion extends from the trailing edge convexly relative to the peripheral surface of the sealing rotor.

  • Patent number: 4627043
    Abstract: Disclosed is a head shifting apparatus for shifting a head relative to a recording medium, which includes a shifting mechanism for shifting the head stepwise, and detecting apparatus for detecting when the head reaches a predetermined reference position. Control apparatus controls the shifting mechanism in such a manner that the head is shifted in a first shifting mode where the head is shifted on the basis of a predetermined first shifting step unit increment until the head reaches the reference position. Then it performs normal recording or reproducing. The head is shifted in a second shifting mode where it is shifted on the basis of a predetermined second shifting step unit increment larger than the first shifting step unit increment.

  • Patent number: 4624747
    Abstract: In the distillation of fresh water from sea water, the sea water is passed ownwardly in a falling film evaporator through a multiplicity of vertical tube evaporator (VTE) stages and multiple stage flash (MSF) evaporators. After the sea water passes through the first VTE stage where it forms a liquid component and a steam component, the liquid component is distributed evenly into the next VTE stage while the steam component enters an adjoining MSF stage. Condensed fresh water flows downwardly from one MSF stage to the next and experiences flash evaporation. The sea water or brine component and the fresh water distillate flow downwardly through the VTE and MSF stages so that the brine component can be removed from the final VTE stage and the fresh water distillate from the final MSF stage.

  • Patent number: 4625151
    Abstract: The disclosed flash device is of the kind that incorporates an integrated processing circuit requiring a stable voltage, but one and the same battery supplies both a booster circuit and the processing circuit. The device avoids the drop in voltage to the processing circuit when the booster circuit draws current after a flash by means of a detector circuit that detects the flash or the operation of the booster circuit. A switching circuit responds to the output of the detector circuit and supplies the charge on a back-up capacitor to the integrated processing circuit. Thus, in the event of a flash, the processing circuit which is normally operated by power from the battery is protected from a supply voltage drop by the supply of a voltage from the back-up capacitor.

  • Patent number: 4624440
    Abstract: An adjustable formwork for forming the corner surfaces of concrete structural members includes a first and a second formwork unit. Each formwork unit extends transversely of the other and has a surface which forms one of the concrete surfaces of the concrete structural members and these surfaces define a corner junction line about which the formwork units can be pivotally adjusted relative to one another. One of the formwork units is provided with a circular-arc shaped guide slot and the other has a pair of spaced guide pins secured to it with the pins being movably guided in the slot. The center point of the arc of the slot is located on the corner junction line. The interengagement of the pins with the slot affords a link type guidance between the formwork units. As a result, forces are transmitted at the corner junction line only in the assembly state so that the line lies practically in the plane of the formwork surface which define the concrete surfaces.

  • Patent number: 4624215
    Abstract: In determine and ascertain the physical state of birds and animals in a livestock raising establishment, the batches of such creatures are weighed at certain time intervals, the information on the weight of a bird or an animal is signalled to a computer and is stored in the memory of the latter, the average weight of a number of birds or animals is calculated which gives an indication of the physical state of the respective creatures. To practice the method a weighing apparatus is used including a weighing platform, a load cell attached to the said platform and being capable of converting the pressure of the load on the platform into an electric signal, and an electronic interface adapted to receive the signal and transmit it to a computer with wiring connecting the constituents of the system.

  • Patent number: 4624351
    Abstract: The friction disc clutch for a motor vehicle driven by an internal combustion engine comprises a flywheel which is driven through a rotationally elastic element by the crankshaft of the internal combustion engine. The mass-spring system of the drive path of the clutch is so dimensioned that natural vibrations occur in or below the idling rotation rate range of the internal combustion engine. The rotationally elastic element can be bridged over for rotation rates in the range of and below the idling rotation rate in order to prevent resonance effects in idling and in the starting of the internal combustion engine. The bridge-over clutch can be formed by a pinion of the starter motor. Alternatively, centrifugal clutches can be used.

  • Patent number: 4624504
    Abstract: In the removal of the overburden prior to surface mining of minerals in an elongated pit, one or more first excavating machines remove the overburden along one elongated part of the pit and direct the removed material via a cross-pit transporter across the pit where it is deposited outwardly from and along the opposite side, called the dump side. At least one other excavating machine travels along the remaining elongated part of the pit at a level not higher than the level of the cross-pit transporter and removes the overburden to the same dump side of the pit. The excavating machines moving along the elongated part of the pit operate independently of one another. When the cross-pit transporter and the second excavating machine operating in the remaining elongated part of the pit on the same level, meet while moving in opposite directions, the second excavating machine moves across the pit out of the path of the cross-pit transporter and the transporter is moved past the second excavating machine.

  • Patent number: 4623385
    Abstract: For introducing additives, such as inoculating agents, into a metal bath, the additive is held in a supply container. A slide device carries measured amounts of the additive from the supply container to an immersion pipe extending downwardly into a metal bath located in a vessel. A flow of gas is provided into the immersion pipe adjacent the point where the additive is introduced into the pipe. The gas carries the additive downwardly through the immersion pipe for mixture into the metal bath. The additive can be supplied continuously or in intermittent portions to the immersion pipe. The additive is introduced below the surface of the metal bath in accurately measured amounts in a safe reproducible manner.
