Patent number: 4624351Abstract: 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.Type: GrantFiled: December 11, 1984Date of Patent: November 25, 1986Assignee: Sachs-Systemtechnik GmbHInventors: Dieter Lutz, Wolfgang Thieler

Patent number: 4624440Abstract: 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.Type: GrantFiled: March 14, 1985Date of Patent: November 25, 1986Assignee: Dyckerhoff & Widmann AktiengesellschaftInventor: Wilhelm Buchler

Patent number: 4624504Abstract: 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.Type: GrantFiled: February 27, 1984Date of Patent: November 25, 1986Assignee: Mannesmann AktiengesellschaftInventors: Rudiger Franke, Aby Weiss, Hans Goergen, Christian Niemann-Delius, Frank Kay

Patent number: 4624401Abstract: A device for driving fastening elements, such as nails, staples and the like, includes a magazine extending transversely from a driving unit. A follower is located within the magazine for supplying fastening elements to the driving unit. For filling the magazine with fastening elements, the follower can be secured in a loading position. The follower is secured by a stop pivotally attached to the follower which engages an abutment on the magazine. The follower is released from the loading position by an actuating member movably mounted on the magazine so that it can contact an engagement part on the follower and pivot the stop out of engagement with the abutment.Type: GrantFiled: July 16, 1985Date of Patent: November 25, 1986Assignee: Hilti AktiengesellschaftInventors: Theo Gassner, Rolf Fehr

Patent number: 4625151Abstract: 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.Type: GrantFiled: October 26, 1983Date of Patent: November 25, 1986Assignee: Canon Kabushiki KaishaInventor: Hiroyuki Kataoka

Patent number: 4624747Abstract: 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.Type: GrantFiled: October 9, 1985Date of Patent: November 25, 1986Assignee: D.V.T. Buro fur Anwendung Deutscher Verfahrenstechnik H. MorsyInventor: Gamal el Din Nasser
