摘要： A fuel injection system having a reciprocating control member driven in synchronism with the injection pump for opening a fuel bypass and interrupting the injection process. The control member, during its return stroke, drives the fluid through a controllable throttle channel to create a ''''fluid abutment,'''' i.e., it does not return to the initial position. A second bypass is provided subject to control by the control member as well as by a slide valve; also synchronous with the main pump, the characteristic feature being the coordination of the control member with the slide valve in dependence on the variable position of the fluid abutment and a throttling restriction provided in the second bypass.

摘要： In a centrifugal governor for setting the fuel quantity control member of a fuel injection pump, there is provided an abutment for limiting the displacement of said member. Said abutment is adjustable both linearly along said member and angularly to vary the orientation of a curved abutment edge cooperating with a follower nose connected to said fuel quantity control member.

摘要： In the preparation of Raney alloy fuel cell electrodes using polytetrafluoroethylene as a binder, harmful reaction of the binder with the aluminum or other reactive metal of the Raney alloy is prevented by the presence of finely powdered silver salts which envelop and protect the Raney alloy particles and develop a protecting gas at the sintering temperature of the polytetrafluoroethylene.

摘要： A FUEL INJECTION ARRANGEMENT IN WHICH A MONOSTABLE MULTIVIBRATOR APPLIES CONTROL PULSES TO ELECTROMAGNETICALLY ACTUATED FUEL INJECTION VALVES OF THE ENGINES. A SWITCHING CIRCUIT IS LINKED TO THE THROTTLE OF THE ENGINE FOR THE PURPOSE OF APPLYING AUXILIARY INJECTION BETWEEN EACH TWO SUCCESSIVELY OCCURRING PULSES FROM THE MULTIVIBRATOR WHICH IS ACTUATED SYNCHRONOUSLY WITH THE ROTATIONAL SPEED OF THE ENGINE. THE SWITCHING CIRCUIT INCLUDES A CAM MEMBER WHICH IS COUPLED TO THE THROTTLE THROUGH AN OVERRUNNING SLIP CLUTCH. THE CAM MEMBER IS ROTATED WITH THE THROTTLE ONLY DURING THE OPENING MOTIRON THEREOF, WHEREAS THE CLUTCH DISENGAGES THE CAM MEMBER FROM THE THROTTLE WHEN THE LATTER EXECUTES CLOSING MOTIONS.

摘要： A fuel injection valve which includes a valve needle urged against a valve seat by a closing spring which is disposed between a fixed part of the valve and a spring seat disc supported by a nut threadedly secured to the stem of the valve needle. For varying the preload of the spring, the valve needle is rotated, whereby said nut is axially displaced changing the extent to which said spring is compressed.

摘要： An electrical manicuring apparatus comprises a housing and a cover detachably connectable to the housing for closing an open end of the latter. A motor is arranged in the housing and receives its energy from a self-contained source of electrical energy. A plurality of manicuring tools are removably received in the cover and can be selectively connected with the output shaft of the motor when the cover is removed so that the device can then be used as a manicuring apparatus. In addition to this, the apparatus is provided with an electrically operated device on the cover which is operatively associated with the source of electrical energy when the cover is connected with the housing so that, in this connected state, the apparatus is usable for purposes other than manicuring, for instance as a flashlight or the like.

摘要： In the suction tube of an internal combustion engine there is disposed a regulator member which is displaceable by air pressure against the force of a return spring tensioned as a function of engine temperatures. Said regulator member is associated with a fuel metering device to vary the proportion of fuel in the fuelair mixture. The fuel quantities are also varied as a function of an arbitrarily set butterfly valve disposed in the suction tube.

摘要： A method of and apparatus for treating elements of circular outline. A vessel is provided with guide grooves which are either straight and parallel to one another or are torus-shaped and concentric with one another. The vessel is mounted for tilting movement about a ball and socket joint and accommodates a bath of etching fluid. Disc-shaped elements to be treated are supported on edge in the respective guide grooves. A motor is mounted below the vessel and its output shaft drives a cam follower having at least one ascending and at least one descending surface portion, and in the case of straight parallel guide grooves two rod-shaped follower members are mounted for sliding movement in axial direction of the motor shaft with their ends resting on the cam disc surface and their upper ends engaging the bottom wall of the vessel so that, when they are shifted in axial direction of the motor output shaft, the vessel is tilted alternately to one side and the opposite side about the ball and socket joint. If the guide grooves are torus-shaped, then three such follower members are used which are circumferentially spaced about the axis at equiangular locations.

摘要： A control assembly which can adjust a regulator, gage, switch, potentiometer or another output device as a function of changes in fluid pressure comprises a housing whose chamber accommodates a row of coaxial plungers defining with the housing a series of compartments each communicating with a fluid-operated cylinder and piston unit wherein the pressure of fluid varies. The positions of plungers with reference to each other and with reference to the housing are indicative of fluid pressure in that compartment wherein the pressure is highest whereby a diaphragm, a lever or a like element directly or indirectly detects such positions of the plungers and adjusts the output device as a function of the highest fluid pressure.
