Abstract: To excavate drifts, tunnels, stopes, caverns or the like, tools operating in an undercutting manner are mounted on radially pivotable tool arms, which are located on a rotary working head. With at least one tool (54) on a tool arm (51), a central region (Z) of the rock face is cut radially from the outside inwards by pivoting of the tool arm (32), an outer region (A) surrounding the central region (Z) of the rock face is cut radially from the inside outwards by pivoting of the tool arm (32). Pivot drives (30) for at least some tool arms (31, 32, 33) can be controlled in such a manner that cross-sections with contours deviating from a full circular shape can be cut. Muck removing devices (27, 28) are used for collecting and transporting away the muck produced by the cutting operation.

Abstract: A machine for accumulating folded sheets into brochures wherein the sheets are stapled to each other along fold lines has a rotary transporting device with several axially parallel saddle-like carriers for opened sheets and pushers which advance the sheets along their carriers into the range of a stapling device. The sheets are fed to the carriers at two or more stations which are spaced apart from one another in the axial direction of the transporting device and open the sheets shortly before the sheets reach the respective carriers so that each sheet which is deposited at the first station directly straddles its carrier and each sheet which is deposited at a next station directly straddles the previously deposited sheet. the stapling device has several stapling units which perform a pendulum movement about the axis of the transporting device and are operated to simultaneously apply staples to two or more brochures.

Abstract: A frame for a headlight of a motor vehicle includes a connecting element of thermoplastics secured to a transparent pane of the headlight, and a screening element of rubber which is non-releasably connected to the connecting element. The frame engages the housing of the headlight and is supported on the transparent pane. The frame has a ring-shaped bead abutting against the pane and a ring-shaped lip lying on the body of the motor vehicle.

Abstract: Signatures, newspaper sections or like printed products are temporarily stored between two successive processing machines of a production line by convoluting them onto a rotor with a flexible band so that the products are stored between neighboring convolutions of the band. The products are stored when the output of the preceding machine exceeds the requirements of the next-following machine, and the rotor is caused to pay out stored products when the requirements of the next-following machine exceed the output of the preceding machine. The rotor can store printed products in the form of a stream of spaced-apart products or in the form of a scalloped stream wherein the trailing portion of each preceding product overlaps the leader of the next-following product. A stream of spaced-apart products can be converted into a scalloped stream on its way to the reservoir from a conveyor which connects the preceding machine with the next-following machine.

Abstract: In a bulb assembly of a vehicle headlight the bulb has a socket formed with an outer annular groove which conically converges towards a filament positioned in a lower portion of the bulb. An O-ring inserted into the groove seals the bulb against a headlight reflector in assembly. The width of the groove in the axial direction of the bulb is selected so that upon pulling the bulb out from the reflector the O-ring performs a rolling motion so that a required pulling force is substantially reduced and a danger for a user injury is prevented.

Abstract: The reflector of a headlight is tiltably mounted to a housing by means of an articulated fixed support and by two articulated adjustable supports. Each support includes a first interlocking part step engaging a recess in the housing and a second interlocking part snap engaging a stud at the rear wall of the reflector. The first and second interlocking parts are joined together by a ball and socket joint and all these parts are linked together in the same direction which is parallel to the optical axis of the reflector.

Abstract: Crash or shock absorbing structural components made of fiber reinforced shetic materials and having portions of different diameters including at least one portion of a larger diameter than another portion, are produced by winding synthetic fibers onto a winding arbor (6) in a desired winding pattern. For this purpose a winding support cage (14) is arranged on the winding arbor (6). The winding support cage (14) has circumferential end edges provided with cut-outs (18, 18') for receiving fiber strands. Arresting pins (25, 26) reach into pairs of these cut-outs for temporarily holding the winding support cage (14) against rotation with the winding arbor when a fiber guide (12) moves into a respective starting position for the next winding operation.

Abstract: The present invention is directed to a dental spray hand piece which has a valve for controlling the flow of an agent through an agent line that extends through the hand piece to a spray nozzle and an arrangement for preventing dripping of the agent from an end of the nozzle when the valve stops flow of the agent through the line, characterized by the arrangement for preventing dripping including a hose section of elastic material being positioned between the valve and the nozzle, a thrust piece for acting on the hose section in an arrangement for moving the thrust piece from a position engaging the hose section and a second position partially deforming the hose section from an enlarged cross-section to a cross-section of the flow through the valve. Thus, when the valve stops flow the hose section resumes its enlarged cross-section which causes a suction to draw fluid in the line between the valve and the end of the nozzle inward from the end of the nozzle.
