Patent number: 4476899Abstract: A weaving machine is operationally connected to a shed-forming machine which includes a drive shaft and a braking mechanism. The latter includes a braking disk which is axially slidably supported on the drive shaft of the shed-forming machine. The braking disk can, during movement thereof, come into frictional engagement with a stationary counterpart. In an alternative embodiment, a modified pick-finding device is used as a brake. In the case of a halt of the weaving machine which is to be carried out quickly, for example during a thread break, the braking mechanism of the shed-forming machine is actuated to relieve the braking mechanism of the weaving machine, and thus no great braking action need be transmitted through the drive for the shed-forming machine.Type: GrantFiled: September 27, 1982Date of Patent: October 16, 1984Assignee: Staeubli Ltd.Inventors: Rudolf Schwarz, Walter Kleiner

Patent number: 4458725Abstract: In a pick finder, a gear which is driven by a motor sits on a sleeve, which has thereon a tooth of a single-tooth coupling. For tensioning the return spring which effects engagement of the coupling, the gear has on the front side an annular control cam surface with recesses and cams, and rigid rollers can be brought into contact therewith through axial movement thereof with respect to the shaft. Based on the size and the placement of the respective rollers, engagement thereof with the cam surface on the gear rotated by the drive motor of the pick finder will move the sleeve into a position for pick finding or for slow-speed run of the weaving machine with the shed-forming machine. At the same time, the return spring is tensioned by the force of the motor.Type: GrantFiled: October 20, 1981Date of Patent: July 10, 1984Assignee: Staeubli Ltd.Inventor: Rudolf Schwarz

Patent number: 4455246Abstract: Heat insulation mixtures are employed both in the form of compacts and in the form of loose ballast. Heat insulating materials which contain an opacifier and thereby are impervious to the radiation which occurs possess extraordinarily good insulating activity. By using quartz powder of a specific particle size spectrum as opacifier, there can be attained optimal insulating properties preferred at high temperatures of use. This type of heat insulating material can be produced by mixing the individual components. It can contain known filler components and binders.Type: GrantFiled: May 28, 1982Date of Patent: June 19, 1984Assignee: Degussa AktiengesellschaftInventors: Sabine Schmidt, Peter Kleinschmit, Rudolf Schwarz, Rainer Domesle

Patent number: 4371006Abstract: A reading needle is slidingly supported in a force amplifying bar which is automatically moved up and down and the reading needle reads nonperforated and perforated points of a pattern card. In the case of a perforated point, a pivotal lock member biassed by a spring remains in a first position and pushes a draw arm of a correcting element downwardly unless this draw arm is already in a downward position. When the reading needle reads a nonperforated point, it is moved within the force amplifying bar by the pattern card during forward movement of the force amplifying bar. A sloped surface of a slot in the lock member slides over the head of the reading needle and swings the two-arm lock member to a second position in which one lock member arm reaches within the active range of an offset portion of a second draw arm and tilts the correcting element, whereby a cam surface of a draw hook is supported on an arm of the correcting element.Type: GrantFiled: February 19, 1981Date of Patent: February 1, 1983Assignee: Staeubli Ltd.Inventor: Rudolf Schwarz

Patent number: 4337239Abstract: There is required titanium disulfide of high purity and stoichiometric composition as electrode material for certain types of batteries. With the known process for reacting preheated gaseous titanium tetrachloride with an excess of preheated gaseous hydrogen sulfide at 400.degree. to 600.degree. C., there is obtained a product which is not optimally usable. A titanium disulfide quality of higher purity and stoichiometry is obtained by forcing a deposition of the titanium disulfide on the inner walls of the reactor through regulating the temperature at the reactor walls and/or the residence time of the gaseous mixture. The titanium disulfide can be mechanically stripped off the walls and removed countercurrently to the waste gas stream from the reactor.Type: GrantFiled: November 10, 1980Date of Patent: June 29, 1982Assignee: Degussa AktiengesellschaftInventors: Alexander Ruhs, Rudolf Schwarz, Peter Kleinschmit

Patent number: 4154268Abstract: A method for controlling the heddle movement in a shed-forming machine and apparatus for performing the method. Reading needles are moved into and out of engagement with a pattern card having perforated and nonperforated portions therein actively cooperating with the needles which are adapted to move toward and away therefrom. Power amplifying structure is provided for converting the control operations noted by the reading needles into mechanical movements effecting selected control of the heddles dependent upon the position of the reading needle relative to the pattern card. A lock member is movably supported on a bar and its movement is controlled by whether the reading needle is received into a perforated portion of the pattern card or whether it engages a nonperforated portion of the pattern card. A shifting of the locking member will result in a selected and simultaneous control of a correcting element to either lift a draw hook or lower same into and out of engagement with a draw knife.Type: GrantFiled: January 26, 1977Date of Patent: May 15, 1979Assignee: Staeubli, Ltd.Inventor: Rudolf Schwarz
