Patent DE-2045472-A1 (DE)
Title: Calculation of width of rolled sections
IPC: B21B1/18
Filed: 1970-09-15
Abstract: The increase in width of the workpiece material on rolling through roll grooves is calculated by converting the pass through a groove of any shape into an equivalent pass of a flat material using the theory of plasticity. When this is done, the width of the specific profile beta K is then calculated employing the formula beta K = beta-alpha/c in which beta is the width of the theoretical flat pass, and a and c are constants, which depend only on the sequence of the passes concerned and the geometrical shape of the groove. It is thus possible to draw a straight line graph for a given profile.

Title: Constant dia. and capacity of insulated cable - is attained by control of dielectric constant in response to dia. and capacity measuring
Inventor: OESTREICH ULRICH DIPL ING
IPC: B29C48/92
Filed: 1974-02-04
Abstract: The constant diameter and capacity in a cable wire, extrusion insulated by means of a worm press, is attained by measuring the wire capacity, the wire diameter, and the derivation of the dielectric constant of the wire insulation which depends on the insulation cellular structure. For this purpose the cooling of the wire insulation and/or the temperature of the extruded plastic and/or the preheating of the bare conductor is varied. The actual value of the extruded quantity of the worm press taking account of the dielectrical constant is compared with the required value and, in case of a difference, the extrusion speed and/or the worm press revolutions are altered. Due to the unambiguous relation between the chosen measured quantities a cable with improved characteristic can be obtained.

Title: Aneroid cell pressure change indicator - centrally pivoted contact moved frictionally
IPC: G01L19/00
Filed: 1974-02-27
Abstract: The direction in which a variable is moving, up or down, particularly barometric pressure as indicated by the movement of an arm attached to an aneroid cell, is indicated electrically by signals derived from a two position contact assembly. This assembly has a central contact freely pivoted and with no restoring springs. The arm of the barometer carries a needle like projection (19) which passes through a hole in the central contact. The needle being split exerts frictional forces on the sides of the hole, so that any movement of the arm causes the contact to follow, subsequent movement having no further action on the contact until a reversal of motion occurs. Various battery and bulb circuits are possible.

Title: Welded construction valve housing - has tubular ends blanked off by valve-seat carrying plates with axial welds
Inventor: HOYER ERNST
IPC: F16K27/10
Filed: 1974-06-08
Abstract: For larger heavy duty welded valve housings the problem of manufacturing to close tolerances is aggravated by hard to control post-welding stresses and deformations. By arranging the essential welds in axial direction this problem is partly overcome. A further feature to improve on the problem of uncontrolled stresses is tod esign the blanking plate considerably thicker than the tubular housing. A further arrangement provides a chamfer on the protruding part of the much thicker blanking plate. An alternative provides the weld between the tubular housing and the blanking plates in shape of a "V" opening up to the outside. Alternatively the edge of the tubular housing can be chamfered.
