Abstract:
A power drill has a rotatable spindle extending from a power-unit housing, a chuck body rotationally fixed to the spindle, a jaw guide carried on the chuck body and rotatable relative thereto about the axis, jaws carried in the chuck body, and a pusher element rotatable about the axis in the chuck body and fixed to and bearing axially on the jaws. Screwthreads between the pusher element and the spindle is effective to move the jaws radially on rotation of the spindle about the axis relative to the guide. A coupling sleeve rotationally fixed to the jaw guide is movable between a tightening position rotationally fixed to the housing for movement of the jaws by the pusher element on rotation of the spindle and a drilling position rotationally fixed to the spindle and rotatable relative to the guide for joint rotation of the guide, jaws, and spindle.
Abstract:
A drill chuck has a chuck body having a plurality of angularly spaced and axially extending but angled guide grooves each holding a jaw that is axially displaceable between an axially front closed position and an axially rear open position. Each jaw has an outer edge formed with external teeth, and also has an axially rearwardly directed rear face extending at an acute angle to a plane perpendicular to the axis. A ring rotatable on the body about the axis has an internal screwthread meshing with the teeth, and an adjustment sleeve rotationally coupled to the ring is rotatable to move the jaws between the open and closed positions. A cover disk on the rear end of the body is formed with respective throughgoing chip-discharge holes each having an inner end aligned with a respective one of the grooves and an outwardly open outer end.
Abstract:
A typical power drill has a housing, a drive spindle that can be driven by a motor, and a chuck including a chuck body in which jaws are guided that are adjustable by a threaded connection provided between a driver and a threaded sleeve. A drill spindle and an axially displaceable drive stem can be driven by a motor from its end facing the drive spindle by planetary gearing gearing composed of a sun gear, a planet carrier supporting planet gears, and a ring gear, and comprising a control element. A locking element and a gripping element are provided parallel to the force transmission chain of the drive stem, which elements are rotationally fixed to the housing and can be moved axially by adjusting the control element between the operating modes of the power drill so as to vary the torque acting on the drive stem.
Abstract:
A method for starting an internal combustion engine that is operated with a fuel mixture made of at least two types of fuel. An injection of the fuel into combustion chambers of the internal combustion engine occurs starting at a predefined pressure threshold of the fuel in a fuel supply according to a high-pressure starting mode, and also according to a low-pressure starting mode if the predefined pressure threshold is no longer met. The pressure threshold is selected as a function of the mixture ratio of the fuel types in the fuel mixture. In this way it can be achieved that differences can be taken into consideration in the optimal mixture formation of the fuel types.

Abstract:
Suggested is a procedure for heating up a catalyst in the exhaust gas system of a charged combustion engine by adding air to the exhaust gas system, whereby the added air is taken from a suction system of the combustion engine in the direction of the air current behind a compressor of an exhaust gas turbo charger that is arranged in the suction system. The procedure distinguishes itself thereby that the combustion engine is driven with a direct injection of fuel in its combustion chambers, whereby it is driven after a start-up with an apportionment of a fuel amount, which has to be injected before the beginning of a combustion, into at least two partial injections per ignition, and with a suboptimal ignition angle efficiency. A second independent claim concerns a control unit, which is customized for controlling the course of the procedure.
Abstract:
An apparatus and method for improving flexibility in a user. The apparatus may include: a base frame having forward lateral, medial, and rear lateral supports; a post having a flexible joint and an upper extremity support; and a user support assembly having forward, rear, foot supports. If desired, the post may provide a plurality of non-fixed, upper extremity positions and recoiling from same. The user support assembly may provide a plurality of non-fixed pivot points for conducting compounded progressive stretching of at least one muscle group.
Abstract:
In order to provide a high temperature resistant adhesive based on water glass which is particularly suited for sticking metal substrates and which remains gas-tight and does not lose its electrical insulating properties even at high operational temperatures, it is proposed that the adhesive should comprise an additive in the form of boron nitride.
Abstract:
A new variety of Asiatic hybrid lily plant, particularly distinguished by its very large flowers unusual color and long persistence, both on the plant and as cut flowers.It is also characterized by its regular and attractive inflorescence, the greenish/orange color of its buds, the very large flowers, its characteristic tepal spotting and the brilliant orange color of its flowers.
Abstract:
A front insert receptacle for fastening two members together. The receptacle includes a housing formed with a base and a pair of opposing spaced legs adapted to receive a stud therebetween. A stop surface is on the housing to engage with the upper surface of one member when the receptacle is partially extended through an opening therein. A rotational stop is on the housing to prevent rotation of the housing with respect to the one member when extended therein. A cam surface is located on the housing in the form of an inwardly extending tang on at least one of the legs. A shiftable cam follower in the form of a disc is in the housing initially positioned so that each tang initially engages with the portion of the cam member when the housing is inserted in the opening in the one member. A biasing spring in the housing engages with the cam member and initially biases the cam member against the tangs. When the disc shaped cam member is rotated with respect to the tangs, the portions in engagement with the tangs will disengage therewith whereupon the spring will direct the disengaged portions of the cam follower into engagement with the undersurface of the member in which the receptacle is positioned to lock the receptacle in position on the one member. Stud locking surfaces are located on the housing so that when a stud is engaged with the other member to be fastened and passed into the housing it will lock with the receptacle and hold the two members together.
