Patent number: 10259532Abstract: The control device is for controlling a transmission ratio between a traction means and a wheel set rotatable about a wheel axle and including at least two wheel blades alternatively wrapped around by the traction means. At least one of the wheel blades is composed of several independently adjustable wheel rim segments. The adjustment of the wheel rim segments in relation to a fixed plane (“plane of alignment”) in which the traction means wraps around the wheel set is effected by the control device in a direction substantially transverse to the plane of alignment. The control device includes at least one electrically actuatable control element, in particular a servomotor, provided that the at least one control element is arranged to rotate with the at least two wheel blades.Type: GrantFiled: September 1, 2015Date of Patent: April 16, 2019Assignee: Praxis Works LLCInventor: Gregor Schuster

Patent number: 9499233Abstract: A control mechanism (800) for setting a transmission ratio between a traction means (812), in particular chain, and a wheel set that is rotatable about a wheel axle and includes two or more wheel blades (810, 820, 830), in particular sprocket blades, adjusts the wheel rim sectors relative to a fixed plane of the traction means in a direction transverse to the plane of alignment. At least one of the wheel blades is composed of a plurality of independently adjustable wheel rim sectors (802, 803). By means of a control component (807) mounted decoupled from a rotary movement of the wheel set, a plurality of co-rotating thrust elements (804, 805) are each displaced via rotation-free couplings between a first and a second position at least in the axial direction, wherein each of the wheel rim sectors is connected in a rotationally fixed manner to a respectively associated thrust element.Type: GrantFiled: July 18, 2012Date of Patent: November 22, 2016Assignee: VYRO COMPONENTS GMBHInventor: Gregor Schuster

Patent number: 4377255Abstract: A housed valve which serves to control the flow therethrough of a medium is disclosed. The valve comprises a control member which projects into a flow-through aperture and is supported flexibly and elastically on a guide wire attached to the housing. The guide wire may be made of steel wire, and the support in a fixed relationship with the housing may be such that the axial position of the control member with respect to the flow-through aperture can be influenced in accordance with temperature.Type: GrantFiled: July 11, 1980Date of Patent: March 22, 1983Assignee: Robert Bosch GmbHInventors: Siegfried Holzbaur, Gregor Schuster

Patent number: 4279232Abstract: The invention pertains to a fuel system for internal combustion engines in which the unburned, heated fuel which is permitted to flow back to the tank from the fuel metering assembly is deaerated via an apparatus in order to prevent gases from re-entering the fuel supply pump when the fuel is reinduced thereto. By the inclusion of a jet pump between the fuel return line and the induction line, the degree of efficiency of the fuel supply pump is substantially increased.Type: GrantFiled: December 4, 1978Date of Patent: July 21, 1981Assignee: Robert Bosch GmbHInventors: Gregor Schuster, Johann Schmid, Erwin Schmuck, Klaus Rose

Patent number: 3942493Abstract: What follows is a description of a fuel metering system for internal combustion engines having a measuring probe. The probe monitors the composition of the exhaust gas and produces an output signal which is used to govern the motions of a magnetic valve which in turn regulates the amount of air mixed in with fuel prior to the admission of this mixture to the veturi in the suction tube of the carburator.Type: GrantFiled: September 24, 1973Date of Patent: March 9, 1976Assignee: Robert Bosch GmbHInventors: Ernst Linder, Gregor Schuster
