Patent number: 4388973Abstract: A direct drive for a drill bit in a drill string has a fluid-operated motor within a drive section connected by a gear section to a bearing section whose inner tube is coupled to the drill bit to accommodate axial displacement of the drill bit within the outer tube, spring elements are braced against a radial bearing for the inner tube which has at least one axially defined race. The coupling between the inner tube and the gearing also accommodates such axial displacement and a reservoir for oil is located between the drive and gear sections so that oil can be fed to the gearing, the bearings and to an axial bearing in an annular oil-filled space between the drive and gear sections.Type: GrantFiled: March 31, 1981Date of Patent: June 21, 1983Assignee: Zahnradfabrik Friedrichshafen AktiengesellschaftInventors: Siegfried Winkelmann, Horst Schulz

Patent number: 4351237Abstract: A pressure control arrangement for controlling pressure between a printing roller and an offset roller by measuring a force exerted in a bearing of the printing roller when the latter rotates with an angle .psi.. The arrangement includes a piezoelectric pickup positioned on the internal surface of the bearing of the printing roller, a measured pressure value processor for receiving a signal from the piezoelectric pickup, an indicator generating a signal corresponding to a desired pressure value and means to compare the first abovementioned signal with the second mentioned signal. The arrangement also includes a positioner circuit which receives the compared signal and applies the same to a drive member which adjusts the position of the bearing of the offset roller thereby adjusting printing pressure between two contacting rollers for printing on sheets of paper.Type: GrantFiled: June 5, 1980Date of Patent: September 28, 1982Assignee: Veb Kombinat Polygraph "Werner Lamberz" LeipzigInventors: Hans-Jurgen Tappert, Horst Schulz, Hans Johne, Albrecht Johne

Patent number: 4312137Abstract: A printing press includes an impression cylinder formed with axially directed channels for sheet-clamping means, a radiant dryer arranged above the impression cylinder to radiate heat on the printed sheet, a screening hood mechanism tiltably mounted for movement between an inactive position in which the sheet is exposed to heat rays from the dryer and a screening position; the driving motor is connected to the power source by two parallel power supply circuits each including a separate switch, one of the switches being actuated by a relay which in turn is actuated by series-connected contacts closed respectively when the dryer is in operation, when the driving motor is disconnected, when the printing machine stops, and when the channel for the clamping means on the impression cylinder is not facing the dryer.Type: GrantFiled: January 25, 1980Date of Patent: January 26, 1982Assignee: Veb Kombinat Polygraph "Werner Lamberz" LeipzigInventors: Hans Johne, Christian Lucas, Karl-Heinz Foerster, Klaus Schanze, Arndt Jentsch, Wolfgang Mueller, Horst Schulz

Patent number: 4254669Abstract: A shaft transmission has coaxial tubular input and output shafts extending forwardly and backwardly from the transmission. Front and rear planet assemblies in the transmission include respective sun gears, planet carriers, and ring gears. The front planet carrier is fixed on an outer shaft enclosing the entire transmission. The rear sun gear is fixed rotationally to the input shaft. The rear planet carrier is fixed rotationally both to the front sun gear and to the output shaft. The rear ring gear is fixed rotationally to the front ring gear. Such a transmission divides the load between the front and rear planet assemblies while giving a substantial stepdown in the neighborhood of 4:1. In addition the input and output shafts form a throughgoing passage through which a fluid medium, such as drilling mud, can be passed.Type: GrantFiled: June 29, 1979Date of Patent: March 10, 1981Assignee: Zahnradfabrik Friedrichshafen AktiengesellschaftInventor: Horst Schulz

Patent number: 4188883Abstract: A rotary printing machine has at least two successive printing stations. A self-contained aggregate is located between these printing stations and can be inserted and removed from between them as a unit. The aggregate has a transfer roller which receives sheets from one of the printing stations, one or more heaters for heating the sheets on the transfer roller, and a reversing roller which receives sheets from the transfer roller, selectively reverses them and furnishes them to the other of the printing stations.Type: GrantFiled: May 18, 1978Date of Patent: February 19, 1980Assignee: VEB Polygraph Leipzig Kombinat fur Polygraphische Maschinen und AusrustungenInventors: Helmut Schone, Hans Johne, Alfred Schott, Horst Schulz, Otfried Rudolh

Patent number: 4059028Abstract: In a multiple speed hub with coaster brake for a bicycle, unintentional jamming of the brake is prevented by the provision of novel pawl clutches interposed between a planetary transmission and the hub shell. The recesses of pawl carriers pivotally receiving the clutch pawls are circumferentially oversized to permit limited circumferential movement of each pawl between a driving position and an idling position.Type: GrantFiled: March 25, 1976Date of Patent: November 22, 1977Assignee: Fichtel & Sachs AGInventors: Horst Schulz, Josef Flosser, Reinhard Kessler, Karl-Heinz Schmidt, Ewald Eisend, Erich Hild, Karl-Heinz Loffler, Werner Steuer

Patent number: 3995503Abstract: The transmission ratio of a multiple-speed hub for a bicycle or like vehicle may be changed by axially shifting the ring gear of a planetary gear transmission in the hub shell against the restraint of a return spring. A pawl on the ring gear and/or ratchet teeth on the hub shell have cooperating engagement faces which are obliquely inclined relative to the hub axis in such a manner that the driving force transmitted by the pawl to the ring gear has an axial component in the direction of the return spring action, thereby further axially securing the ring gear in at least one speed position of the hub, minimizing avoidable clearances, and reducing wear of the gear elements.Type: GrantFiled: May 15, 1975Date of Patent: December 7, 1976Assignee: Fichtel & Sachs A.G.Inventor: Horst Schulz
-
Patent number: 3951293Abstract: A gas-permeable liquid closure for containers of liquids or solids which emit or absorb gas is provided by a film of an unsintered tetrafluoroethylene having a thickness of from about 0.1 to 3 mm., a fibrillated structure and a density of less than about 1.4. The film is supported across an opening of the container by a perforated cap or perforated sealing diaphragm which is disposed on either one or both sides of the film.Type: GrantFiled: January 21, 1975Date of Patent: April 20, 1976Assignee: Riedel-De Haen AktiengesellschaftInventor: Horst Schulz

Patent number: 3937309Abstract: The driver in a three-speed bicycle hub may be coupled alternatively with the planet carrier or the ring gear of the planetary gear transmission in the hub shell by means of radial arms on a coupling sleeve which is shifted axially between terminal positions of engagement with the carrier and the ring gear respectively for highest and intermediate transmission ratio. The engaged ring gear may further be shifted axially by the coupling sleeve from its normal position against the restraint of a spring to establish a third, lower transmission ratio. The coupling elements of the planet carrier and ring gear are normally closer to each other than the axial length of the coupling sleeve arms. The radial arms cammingly cooperate with coupling elements on the planet carrier and/or the ring gear to shift the arms automatically into a terminal position from any intermediate position in response to relative rotation of the associated transmission members.Type: GrantFiled: July 10, 1974Date of Patent: February 10, 1976Assignee: Fichtel & Sachs AGInventors: Horst Schulz, Erich Hild, Werner Steuer, Karl-Heinz Schmidt, Ewald Eisend, Karlheinz Loffler, Josef Flosser, Reinhard Kessler
