IPC: G06F19/00
Filed: 1981-06-16
Abstract: An appliance including a digital programming device for forming a sequence of control signals. When the device is switched on by way of the power supply plug, an unpredictable switch-on phenomenon occurs and the program memory is liable to be addressed in a variety of locations. Therefore, during a preparation routine the start conditions are realized. Furthermore, a multi-bit code is generated and stored in a volatile section of the memory. The operative routine comprises a sub-routine which tests this code. If the code is not correct, the preparation routine has not been followed when the appliance was switched-on. The operative routine is then interrupted and first the preparation routine is executed. All further locations in the non-volatile memory section preferably refer to the preparation routine.

Abstract: The device (20) comprises a threaded rod (21) which can be screwed in a block integral to a fixed portion of the trailer or semitrailer (1) and has one end thereof idly engaged in a body integral to a linkage (24, 29, 30, 35) leading to the levers which actuate the brakes (3) of an axle of the trailer or semitrailer (1). By screwing or unscrewing the threaded rod (21) in said block it is possible to achieve the locking or the releasing of brakes (3). When brakes (3) are in their locking position, acting on a latch control member operable by means of a key it is possible to engage one end of the latch within an annular groove formed in the threaded rod, so that the latter is prevented from moving axially. During this stage the other end of the latch acts on a non-return valve (49) connected to the service brake circuit in order to allow the brake fluid to flow in one direction only.

Abstract: Water is enriched with hydrogen and, in a ground-water catchment area (2), passed into the soil (1). Under the anaerobic conditions in the soil (1), microorganisms decompose the nitrate content of the ground-water directly in the soil (1) by an autotrophic denitrification process. If the hydrogen is replaced by organic carbon, the same decomposition process takes place in the heterotrophic process. Expenditure for investments and space requirements for denitrification plants are considerably reduced by the novel process.   <IMAGE>

Abstract: Process for the removal of urea, ammonia and carbon dioxide from dilute aqueous solutions, obtained as process condensates in coupled ammonia and urea syntheses, by hydrolysis of urea and desorption of ammonia and carbon dioxide. Process condensate poor in ammonia is treated with steam in a reaction column at a pressure of 15-42 bar and a temperature of 200-320°C, a gas mixture containing ammonia, carbon dioxide and water is carried off from the top of the reaction column and an aqueous liquid virtually free of urea, ammonia and carbon dioxide is carried off from the bottom of the reaction column. Prior to the treatment in the reaction column, ammonia and carbon dioxide are removed, at a pressure of 1-5 bar, from the process condensate of the urea synthesis. Preferably the quantity of ammonia in the process condensate to be treated is reduced to less than 0.3% by weight.

Abstract: The problem of inaccuracy in known techniques of detecting ethylene oxide in practice are overcome by an indicator which comprises a substrate (1) impregnated with a solution of 4-(4-nitro-benzyl)pyridine and an envelope (2) completely enclosing said impregnated substrate (1), at least a part of which envelope (2) is transparent to enable observation of the colour of the substrate (1) and which envelope (2) has low permeability to gaseous ethylene oxide. With this indicator, the amount of ethylene oxide remaining in, for example, medical instruments after their sterilisation with ethylene oxide may be estimated by the naked eye since the colour of the indicator changes step by step with the release of residual ethylene oxide.

Abstract: In this pump system a pump (1) is attached to the axle (4) or wheel hub of the wheel. At the upper end, a crossbar (2) is located. In addition eccentric running rails (3) are attached to the frame (5) of the vehicle. If the wheel is rotated and the crossbar (2) engages on the eccentrically formed running rail (3), the upper part (6) of the pump begins to press into the lower part (7) of the pump and the pumping process begins. The curvature of the running rail (3) is matched to the travel path of the pump in such a way that the maximum travel is achieved at the end of the eccentric curvature. A compression spring (19) returns the pump part into which initial position. The air is forced by the pump (1) through a tube or hose connection (16) via a valve (17) into the hose or tyre (18). The overpressure is controlled by an overpressure valve (20) which alerts the user by means of a whistle tone. The pumping process is switched off by moving the crossbar (2) through 90 degrees. <IMAGE>

Abstract: ardiac ventricular fibrillation and other tachyarrhythmias are controlled by delivery of two current pulses to separate pairs of electrodes orthogonally placed around the heart, preferably in the epicardial-pericardial space. The technique produces a temporal and spatial summation of the delivered current, which results in a dramatic reduction in the voltage, current, and energy required for defibrillation, or cardioversion, and allows the use of a smaller implantable pulse generator. The new system achieves a more uniform distribution of current within the ventricular myocardium, thereby reducing the risk of tissue damage and increasing the margin of safety between effective shocks and myocardial depressing or damaging shocks.
