Title: Lightweight building block prodn. - uses shredded softened used paper with cement
IPC: C04B18/24
Filed: 1990-02-23
Abstract: To produce building blocks and components, to develop walls and other construction parts, untreated used paper is softened for 24 hrs. in water, and the wet material is reduced in a shredding type appts. The damp and reduced material is mixed with cement in a ratio of about 6:1 in a cement mixer with water feed. The mixt. is placed in a mould and compressed. After moulding, the block is dried in air for two to four weeks. The mould, filled with the mixt. is subjected to a given pressure. Increased cement content increases the compression strength of the building block. A reinforcement can also be introduced into the mixt. in the mould. ADVANTAGE - Gives lightweight building blocks, with an unlimited supply of free raw material for the additives.

Abstract: Detection of danger or damage to catalysts (IA) or catalytic coatings (IB) and detection of misfiring, esp. detection of oxidisable mixts. contg. O2 and/or ageing and/or signas or poisoning of (I) in i.e. engines involves evaluating at least two measurements, each subject to different catalytic effects.

Pref. one depends on the temp. and the change in temp. when the hydrocarbon/air mixts. reacts on the catalyst, esp. the change in temp. of an O2 sensor, is determined. The temp. sensor pref. consists (partly) of catalytic material. The difference between the temp. at points strongly and not or only slightly affected by (I) may be used, pref. with an O2 sensor at the second point. USE - The technique is esp. used for monitoring the catalyst function, misfiring and/or variable injection.
Patent DE-4022495-A1 (DE)

IPC: G01P9/04
Filed: 1990-07-14
Abstract: Proposed is a rotational-speed sensor produced from a mono-crystalline silicon wafer and having at least a pair of oscillators which are connected by one or more strips to a fixed frame. The osciallators can oscillate in two mutually perpendicular directions. The sensor element is fitted with means for exciting the oscillators to oscillate in a first direction and means for detecting deviations in the oscillations of the oscillators in a second direction perpendicular to the first. In addition, the sensor element has at least one resist on which a fixed electrode designed as a plate-condensor electrode is mounted. Each oscillator forms an opposite electrode of this plate condensor. The connection strips also act as electrical lines for the oscillator exciter current and for leading the oscillator signals in and out.

Abstract: The control system to establish irregular steam feed to an autoclave, for decatising woven piecegoods, has a second thermometer (T2) parallel to the main thermometer (T1), set to a lower temp. than the main unit. Should the set temp. be reached in a shorter time span than set in the timer (3), an autoclave (A) fault is indicated. Pref. the second thermometer (T2) is inserted into a separate channel (2) from the main thermometer, leading to a separate outlet which can be opened as an alternative to the main outlet. The timer (3) closes the second outlet, after a given time, simultaneously with the opening of the main outlet (1). The main channel (1) for the air outlet is connected to the exit (7) through the main outlet (8) and valve (9). The second outlet channel (2) is linked to the exit (7) through an additional outlet (10) behind the main outlet (8) in relation to the flow direction from the autoclave (A). At the start of each decating cycle, the valve (9) is closed and the other valve (11) is opened. A timer (3) controls the closing of one valve (11) synchronised with the opening of the other valve (9). A vacuum pump evacuates the autoclave (A), and steam is passed in (4) after or at the same time as the evacuation. At the start of the steam feed, the second outlet channel (11) and the valve (9) to the main outlet is closed. ADVANTAGE - The appts. gives a simple indication that the operating conditions are not correct, to prevent faulty treatment.

Title: Extinguishing oil well or natural gas fires without use of water or foam supplies - uses a remote controlled vehicle to position a flame snuffing tube
Inventor: STEINBACH WOLFGANG DR ING
IPC: A62C3/02
Filed: 1991-03-30
Abstract: A flame proof collector pipe is positioned over the escaping gas or liquid by a frame, which ensures that the collector pipe maintains a sealed fit over the escape. The flame is thereby trapped in the collector pipe. The length and cross sectional area of the collector pipe is such that the nominal amt. of air in the pipe is insufficient to support combustion of the gases. The length of the pipe is selected, typically 10 to 20m, so that the temp. of the gas at the end of the pipe is below its flash point. The frame and collector pipe assembly is carried by a remote controlled tracked vehicle, equipped with television and infra-red cameras. ADVANTAGE - Used for extinguishing oil well or natural gas fires. Enables fires to be extinguished in situations where water or foam resources are limited. Effective even where the surroundings have been heated due to the length of time of burning, and where the possibility of self ignition is high.
