Patent DE-4022543-C1 (DE)
IPC: F16L55/18
Filed: 1990-07-16
Granted: 1992-01-30
Abstract: When replacing parts in a piping system, it is sometimes necessary to cut off a pipe (2) from the inside by mechanical cutting, using a device inserted into the pipe (2). The invention calls for a device with a manipulator (6) which can be inserted into the pipe (2) and displaced inside the pipe (2), the manipulator having amilling head (15) which can be adjusted at right angles to the pipe axis (4) and can be rotated about the pipe axis (4). The use of a milling head as the cutting tool for removal of the pipe (2) ensures that it is virtually impossible for the cutting tool to get jammed.

Title: Gripper rail locking slider -  is used on rotary transfer presses and spans tolerance gaps between rail ends
IPC: B21D43/05
Filed: 1991-06-13
Granted: 1992-03-19
Abstract: The gripper rail lock slider spans the gap between the rails and rides into one end out of the other and is fitted with clamps which are moved into their clamping position when the slider trips an axial pushrod and subordinated wedges, thus axially clamping the two rails. The nontwisting slider (7) should have an endstop (5, 6, 8, 9) and there is an axially operating compressive spring coupling (13) between the slider and the axially guided pushrod (12) within the slider. The rod only acts on the wedges (20, 21) when the slider is at end point and thus forces the wedges out so as to engage cylindrical pins in the end (10) of the other rail (3). USE/ADVANTAGE - Rotary transfer presses. Locking slider spans all tolerances gaps and axially locates rail ends without axial load during clamping.

Title: Current meter

Granted: 1995-12-20
Abstract: FIELD: measuring equipment. SUBSTANCE: meter is comprised of four inclined posts whose ends carry four hydroacoustic converters. Some of these converters are installed parallel to the axis of the outer ring of the outer gimbal suspension of a ferrum-probe converter while the other ones, parallel to the axis of its inner ring. Each hydroacoustic converter is made as a pair of piezoelements whose planes are set at an angle of 120 deg. Arrangement of measurement axes over the perimeter of the meter working volume dispenses with various posts in its center. Elimination of structural members in the meter internal volume and a considerable reduction of the number of posts diminish the level of disturbances of natural flow which promotes reliability of measurement data. The hydroacoustic converters are installed on posts which are inclined to the flow and whose hydrodynamic resistance is smaller than that of the posts arranged square to the flow. The design of the meter is simplified by making all angles between the measuring axes of the three-dimensional quadrangle equal to 60 deg which provides for identical design of all the four hydroacoustic converters wherein the piezoelements are set at an angle of 120 deg. The provision of four inclined posts supporting the hydroacoustic converters also simplifies the design of the current meter. EFFECT: improved design. 3 dwg
