Patent DE-2354307-A1 (DE)
Title: Pressure measurement using cholesteric mesophase - with reversibly pressure-dependent reflection colours, for accuracy and simplicity
Inventor: STEGEMEYER HORST PROF DR
IPC: G01L9/00
Filed: 1973-10-27
Abstract: Pressure measurement is carried out by exposing a cholesteric mesophase (I), with reversibly pressure-dependent reflection colours, to the pressure to be measured and measuring the resultant spectral shift of the light reflected from this. (I) pref. consists of a mixt. of cholesteryl oleyl carbonate, cholesteryl myristate or cholesteryl nonanoate with cholesteryl chloride. The appts. used consists of a sealed housing contg. (I) with part of the walls ensuring transfer of the pressure to be measured to (I) and a window for illuminating (I) and transmission of the reflected light. No connections between the measuring cell and the display are necessary, so that measurement is possible in situation which are difficult to reach with leads. The light from the cell can be transmitted by fibre optics for analysis and display. Correlation of the pressure with colour makes the process very suitable for pressure monitoring, e.g. in autoclaves, with the possibility of automatic regulation of pressure by an optical-photoelectric system. The system is also insensitive to excessive pressures, outside the measuring range, and not damaged by these. A wide range of pressures can be accommodated by the use of a series of suitable cells. Measurement is very accurate and the cell used is small and simple.

IPC: C07C7/00
Filed: 1973-11-27
Abstract: Non-volatile aromatic and aliphatic hydrocarbons are separated from mixts. with other hydrocarbons and organic cpd. by (A) shaking or extracting with n-hexane or n-heptane, (B) adding the soln. to a column filled with silica gel, (C) eluting the aliphatics with an 1:9 by vol. mixt. of n-hexane/n-heptane until completely removed from the column while the aromatics, as visible in long-wave U.V. light are still in the middle of the column, and (D) eluting of the aromatics. The process is useful in the extraction of non-volatile aromatics and aliphatics and determination of their content in mixtures e.g. atmospheric dust, paraffins for medicinal and cosmetic purposes, etc.

Title: Power brake control system - has pistons in piping from valve to brake cylinders actuated by pedal
Inventor: LEIBER HEINZ
IPC: B60T13/18
Filed: 1973-12-03
Abstract: On actuation of the brake pedal a valve is opened between a pressure source and the wheel cylinders, which are subjected to a controlled pressure, while in the event of pressure failure the pedal actuates an auxiliary plunger after travelling its full distance. In the piping from the valve to two sets of wheel brake cylinders, cylindrical chambers are incorporated, in which pistons are held by preloading and the controlled pressure in an initial position. The passages supplying pressure to these cylindrical chambers are shut off by slight movement of the respective pistons, and one face of the second piston is subjected to the pressure from the chamber containing the first one. A force dependent on the pedal actuating force is exerted on the first piston.

Title: Control system for gear cutting machine indexing clutch - has rotating speed converter with two inputs and one input drive
Inventor: LIESBERG KLAUS
IPC: B23Q16/02
Filed: 1975-01-24
Abstract: The clutch of the gear cutting machine tool has halves which are engaged during the indexing movement and the clutch is open during the cutting process and the separated clutch halves rotate relative to each other during this period. The drive can be transmitted through either of the clutch halves will assume the same relative angular position to each other after the indexing movement. Each coupling half is connected toa drive shaft. Owing to the parallel arrangement of the speed converter it is not in the power system of the rotating drive and can be therefore small and its manufacturing tolerances need not be accurate. The driven shaft is connected to the storage unit in the diagram which actuates the signal generator whose pulses control the engagement of the clutch.

Title: Burner without air and fuel premixer - has streamlined fuel supply profiles in air flow channel to burner
Inventor: MATZKE KLAUS DIPL ING
IPC: F23D14/74
Filed: 1975-02-28
Abstract: The burner does not use premixing process and air is blown past guide profiles which have transverse outlets for fuel, this reduces pressure loss due to flow resistance in the burner and it represents a simple means for controlling flame length and temperature and generates a stable frame. The fuel oil or gas is pumped into stream-lined profiles (2) which have lateral outlets (3). The fuel stream emerges into the air stram and a turbulent mixture is formed on the flame side. The flame is stabilised by the streamlined profiles. The fuel serves also as a coolant for these profiles.
