Title: Housing for a pressure sensor indicator device, especially for measuring air-bottle pressure in diving gear
Inventor: KELLER HANS W
IPC: G01L9/00
Filed: 1988-02-24
Abstract: Housing for a pressure sensor indicator device, especially for measuring air-bottle pressure in diving gear. Traditional housings for a pressure sensor indicator device require a considerable constructional cost in order to ensure corresponding sealing to the exterior. The housings are also sensitive to shock under certain conditions. In the event of penetration by oxygen overpressure, they can burst, in particular in diving technology. These disadvantages are overcome by the fact that the housing (1) comprises a housing body and housing jacket (7), which can be closed with a cover and bottom (5), preferably by using sealing elements (13), the housing (1) thus formed being jacketed or surrounded by means of a flexible body (35). This flexible body (35) moreover also holds the cover and/or bottom (5) on the remaining housing body or housing jacket (7). The housing is suitable for all applications, including measuring air-bottle pressure in diving technology. <IMAGE>

IPC: B21B37/16
Filed: 1988-03-07
Abstract: A method for controlling the gap width between the work rolls of a cold-rolling stand for the production of strip from metal and a device for carrying out the method. Strip sections of predetermined length are scanned continuously at the inlet and outlet and gating times are formed, these being inversely proportional to the strip speed. The gating times are counted by means of counting pulses, the frequency of which is proportional to the strip speed at the outlet. The count values are combined in a manner correct in terms of time in a digital computer with a value measured at the inlet for the thickness deviation of the strip from the desired thickness and, together with input desired values for the strip thickness at the inlet and outlet, a correction value is calculated, this being fed in analogue form to a controller which controls the hydraulic positioning device for the work rolls.
