Patent number: 4595134Abstract: In an explosive charge operated device for driving fastening elements into a receiving material, a throttling device is arranged for conveying explosive gases from a barrel out of the device housing. The throttling device is a tubular member containing a displaceable nozzle needle. The position of the nozzle needle controls the flow of gas out of the tubular member. When an explosive charge is fired, the barrel is axially displaceable opposite to the direction for driving a fastening element from the device. As the barrel is displaced the throttling cross-section through the throttling member is increased as the throttling member is displaced so that the outflow of the explosive gases and the peak values of the sound level is considerably reduced as compared to similar previously known devices.Type: GrantFiled: July 25, 1985Date of Patent: June 17, 1986Assignee: Hilti AktiengesellschaftInventor: Peter Jochum

Patent number: 4594841Abstract: In a forage cutter, a cutting wheel is rotatably mounted within a housing. For an angular portion of the wheel relative to the housing, its outer circumferential periphery is positioned adjacent to a backing wall of the housing. Alternating knives and blades are attached to the cutting wheel about its circumferential periphery with the knives coacting with a stationary cutting plate to cut forage material introduced into the housing. After the material is cut it is carried downwardly to a space where it is crushed and the crushed material is moved upwardly by the blades on the cutting wheel to an outlet passageway. The crushing space is provided by diverging the backing wall outwardly from the outer circumferential periphery of the cutting wheel. Following the crushing space, the backing wall converges inwardly toward the outer circumferential periphery of the cutting wheel. The outlet passageway follows the inwardly converging backing wall in the direction of rotation of the cutting wheel.Type: GrantFiled: February 21, 1985Date of Patent: June 17, 1986Assignee: Karl Mengele & Sohne GmbH & Co.Inventors: Eberhard Wistuba, Xaver Lenzer

Patent number: 4594827Abstract: A tension member is secured at each end to a separate anchoring system for transferring the tensile force from the member to a support structure. The tension member is made up of individual elements disposed in parallel over an axial length located between the ends. After the individual elements are tensioned, open spaces around the elements within the tubular casing are filled with cement grout. Between the tubular casing and each anchoring disc the individual elements extend through and are guided within an anchoring pipe. One end of each anchoring pipe bears against the associated anchoring disc and supports the anchoring disc. A radially outwardly and inwardly projecting annular collar is formed in the anchoring pipe and the collar forms an outwardly extending annular shoulder for transferring the load from the anchoring disc to the support structure.Type: GrantFiled: September 24, 1985Date of Patent: June 17, 1986Assignee: Dyckerhoff & Widmann AktiengesellschaftInventor: Klemens Finsterwalder

Patent number: 4595877Abstract: An eddy-current loop detector operates to sense the presence of an electrically conductive object by applying D.C. onto a conducting loop so that a permanent magnetic field is induced, which field partly penetrates into the object; ensuring the quick cessation of self-inductive transient operation of the loop when the D.C. is switched off; and measuring the change in the part of the flux passing through the measuring loop arising from eddy-currents induced in the conductive object, and evaluating such change while the relatively slowly decreasing flux is maintained. By repeating these operations with the desired frequency, the eddy-current detector is well suited for continuous measuring of the position of the object.Type: GrantFiled: October 18, 1984Date of Patent: June 17, 1986Assignee: Vilati Villamos Automatika Fovallalkozo es Gyarto VallalatInventor: Karoly Dulk

Patent number: 4595270Abstract: The disclosed finder system includes, from front to rear, a first objective lens of negative power, an optical member having a half-mirror, an eyepiece of positive power and a viewfinder frame arranged near the eyepiece to be observed by the eyepiece with the aid of a reflection from the half-mirror. The finder system satisfies the condition 0.2<d/D<0.6 where D is the air separation between the first objective lens and the eyepiece lens and d is the air separation between the optical member and the eyepiece lens. Thus the first objective lens is exchangeable for a second objective lens of different power from that of the first objective lens to change the magnification of the finder system.Type: GrantFiled: April 23, 1984Date of Patent: June 17, 1986Assignee: Canon Kabushiki KaishaInventors: Yasuyuki Yamada, Kazuo Fujibayashi, Yasuhisa Sato, Hideo Yokota

Patent number: 4594729Abstract: In providing stereophonic reproduction of sound in the passenger space of a motor vehicle, a pair of speakers are located at the opposite ends of the dashboard ahead of the driver, one for reproducing the left signal of a sound recording and the other for reproducing the right signal. In addition, at least one of a summation signal made up of the left signal and the right signal is provided from a speaker located at the dashboard between the pair of speakers, and a differential signal, made up of the left signal and the right signal, is directed forwardly from the rear of the passenger space. Further, the differential signal can be made up only of middle and lower frequencies supplied to one rear speaker with another rear speaker turned 90.degree. relative to the one rear speaker and radiating the differential signal to opposite sides of the passenger space. An electronic delay can be incorporated into the rear speakers.Type: GrantFiled: April 20, 1983Date of Patent: June 10, 1986Assignee: Neutrik AktiengesellschaftInventor: Bernhard Weingartner

Patent number: 4592560Abstract: A hand-held device for use in drilling or the like includes a tool holder mounted on a rotating spindle. The tool holder is secured to the spindle so that there is no relative rotation between them. The tool holder has a support ring for securing locking elements in locking engagement within recesses in the spindle. A blocking element secures the support ring against rotation so that the locking engagement is maintained. By releasing the blocking element, the support ring can be rotated releasing the locking elements so that the tool holder can be removed from the spindle.Type: GrantFiled: March 20, 1984Date of Patent: June 3, 1986Assignee: Hilti AktiengesellschaftInventors: Anton Neumaier, Werner Theissig

Patent number: 4592456Abstract: The viscous coupling for a cooling air fan, especially of an internal combustion engine, comprises a drive shaft rotatable about a rotation axis, on which a housing is rotatably mounted. A partition divides the housing into a reservoir for a viscous shear fluid and a working chamber. In the working chamber there is arranged a rotor non-rotatably held on the drive shaft. The rotor together with the housing or its partition defines at least one shear gap. A controllable valve device connecting the reservoir with the working chamber controls the inflow of the shear fluid from the reservoir into the working chamber, especially in dependence upon temperature. Adjoining the partition the working chamber possesses in the region of the external circumference of the rotor an annular space formed at least partly by the rotor. The partition contains at least one over-flow opening for the shear fluid, opening into the annular space.Type: GrantFiled: August 8, 1984Date of Patent: June 3, 1986Assignee: Fichtel & Sachs AGInventor: Dieter Neugebauer
