Title: Storage and transport of microorganisms - by storing microorganisms as air dried cultures on solid nutrient medium to retain viability for long periods
Inventor: RUDAT AXEL DR
IPC: C12N1/04
Filed: 1991-07-09
Abstract: Microorganisms are stored and/or transported in the form of a film produced by culturing the microorganisms under sterile conditions (without access to foreign microorganisms) on a thin film of a gelled or swellable solid nutrient medium initially satd. with water, and air drying the film for a time that is a multiple of the cell division cycle time of the microorganisms. The dried films are removed from the culture vessel under sterile conditions and packaged in polymer film containers. ADVANTAGE - The microorganisms remain viable for long periods, e.g., 12-36 months. The process is applicable to a wide range of microorganisms, including non-sporogenic bacteria and fungi and the mycelia of higher fungi. In an example, microorganisms were grown on nutrient agar in Petri dishes under ambient conditions for several weeks while allowing the agar to dry. On storage, Anabaena variabilis and Nostoc muscorum remained viable for 36 months and Saccharomyces cerevisiae and Pleurotus ostreatus remained viable for 12 months.

The parts are connected to each other by soldering or adhesion. USE/ADVANTAGE - Used for the prodn. of several door panels with different coordinated designs.
Patent DE-4136338-A1 (DE)
IPC: G06F11/16
Filed: 1991-11-05
Abstract: The proposal is for a process for dealing with errors in electronic control devices. It also comprises a device for controlling the steering angle of the rear wheels of a motor vehicle. The control device controls a setting device to which the safety device is attached. In the control device's main function transmitter signals are detected, settings calculated and the setting device controlled in accordance with the calculated values. The consistency of the calculated settings and the transmitter signals detected is tested. The testing of the values includes a decision whether the main function is further processed or one of two emergency measures is taken. In the first emergency measure the safety device is actuated and the control of the setting device switched off. In the second, the signals from transmitters are detected further and settings calculated therefrom. Before the adjustment of the setting device, the calculated settings are multiplied by a factor becoming smaller with time in order to attain a slow decay in the setting amplitude of the setting device.

Title: Mill for grinding brittle material such as slag or clinker - has sensor to measure amplitude of vibration and vary gap between rollers and pan to minimise vibration
Inventor: BRUNDIEK HORST
IPC: B02C15/00
Filed: 1992-01-31
Abstract: An air-swept grinding mill for grinding brittle material, such as slag or cement clinker, has a rotating pan (3) which rotates about a vertical axis (28). The pan cooperates with a pair of grinding rollers (1a) and a pair of pre-compression rollers (2a). These rollers are mounted on swinging arms actuated by hydraulic cylinders which enable the gap between each roller and the surface of the pan to be adjusted. A sensing device measures the amplitude of vibration of the mill and generates a signal which is used to adjust the gap between rollers and pan and consequently vary the speed of the rollers in order to minimise the vibration. USE/ADVANTAGE - Reduction of mill vibration to maintain continuity of mill output.

Title: Visual inspection method and device for carrying it out
Inventor: TUTSCH ELLI
IPC: G01N21/88
Filed: 1993-03-10
Abstract: Manual visual inspection methods are disclosed, the common inventive concept of which is to carry out inputting of the fault location simultaneously with observation of the test-piece, which saves a working step and makes carrying out the inspection method even more user-friendly since the checker does not continuously need to look back and forth between the test-piece and screen or file card, which experience shows to lead to faster tiring of the eyes.
Patent DE-4308758-A1 (DE)
Title: Control aid for hang-gliders and ultralight aircraft (trikes)
Inventor: ERB PETER
IPC: B64C31/028
Filed: 1993-03-19
Abstract: The lateral control of present-day hang-gliders having a floating keel tube is based, in addition to the lateral displacement of the pilot's weight, on the use of so-called sail control. However, this control is lost as the sail stress increases. The capability to realise a greater sail stress is desirable for flight performance reasons. The invention has the object of ensuring sail control even when the sail stress is increased in the case of conventionally constructed or cantilever construction hang-gliders and ultralight aircraft (trikes). To this end, the lateral lower bracing means are not firmly connected at their outer ends to the transverse tubes, as is normal, but are guided back via deflection means into the keel tube region and are fastened there in such a manner that the difference between their cable forces (left/right lower bracing means) is introduced into the sail. Using this design, in the case of a lateral control movement by the pilot, the force which displaces the keel tube (sail) is more than doubled. A quite considerable sail control effect is thus obtained even in the case of relatively high sail stresses. The structural concept of the present-day gliders is in this case essentially maintained.
