Title: Method and device for storing energy
Inventor: DAIMLER BERTHOLD H DR
IPC: B60G11/30
Filed: 1981-03-16
Abstract: Pressurised storage of gases, liquids or powders in containers which become elastically deformed depending on the pressure whilst maintaining the shape without external friction. The container wall consists of elastomer, corrugated or folded membranes, whose restoring force can be increased by prestress, additional springs and ballast weights. Gas filling offers an additional pneumatic energy store, liquid filling a thermal store. An axially elastic circular cylinder as a preferred embodiment with an elastomer membrane, reinforced unidirectionally transversely to the direction of extension, achieves a high density of stored energy with optimum stress distribution. The materials and pressure media required are adequately available in plentiful quantities and are non-harmful to the environment. The container size can be in cubic centimetres, litres or cubic metres and change in volume, for example, 50 to 150% under maximum pressures of, for example, 1 to 20 bar. The filling speed, removal speed and duration of storage are virtually unlimited.

Title: Pneumatically resilient mixing-arm mount in a positive-mixer rotor consisting of tube sockets with vertical and horizontal mixing-arm adjustment device for positive mixers
Inventor: DICK WERNER
IPC: B01F7/16
Filed: 1981-05-12
Abstract: The invention relates to a positive-mixer rotor consisting of a plurality of tube sockets into which the mixing arms are inserted, in the evacuated state, with the mixing-arm mounts, fashioned from pneumatic-tyre wheels prepared for high pressures, and are retained and cushioned therein by a high air pressure. In this arrangement it is possible, by means of a horizontal and vertical pneumatic mixing-arm adjustment device which is attached to the mixing-arm sections, to adjust, fully automatically or manually, a lateral and vertical mixing-arm positioning mechanism, the vertical adjustment involving regulation of the wear on the mixing blade. The unproblematic manner of mounting and cushioning reduces wear, simplifies handling and extends the field of application of the positive mixer for various materials to be mixed and improves the mixing effect by simple plugging in of special mixing arms, the insulating effect of the pneumatic-tyre hoops also making it possible to use the mixing arms as electrodes (probes) for moisture metres.

Title: >>Method for digital correction of the relationship between a digital input signal and a digital output signal and circuit arrangement to carry out this method<<
Inventor: KOEHLER EBERHARD DIPL ING
IPC: G06F17/17
Filed: 1981-07-16
Abstract: To correct the relationship between a digital input signal and a digital output signal, the digital input signal is combined with a digital correction value to form the digital output signal. For this purpose, the value range of the digital input signal is divided into segments of equal size. The correction values for the limits of the segments are stored in a read-only memory. The correction values for the digital input signal values which lie between two limits are determined by linear interpolation between the correction values of the adjacent limits. If the number of segments is selected as equal to 2<n>, n being a positive integer, the respective segment which is to be taken into consideration is obtained from the n most significant bits of the digital input signal.

Patent DE-3135455-A1 (DE)
Title: Gas-mixing appliance
Inventor: SCHWANBOM ERIC DR
IPC: B01F23/10
Filed: 1981-09-08
Abstract: The invention relates to a gas-mixing appliance, in which the proportions in the mixture of the gases supplied via component feed lines are adjustable and in which the proportion of a gas component is determined according to the duration of the gas flow through a restrictor with a constant inlet pressure (admission pressure) and backpressure. The gas-mixing appliance is improved in terms of mixing accuracy by there being arranged in the feed line (4) to the buffer vessel (7) a restrictor (6) shared by the components, which restrictor (6) can alternately be connected, via a controllable multi-way valve (3), to the individual component feed lines (1, 2). By means of a controller (I), the multi-way valve (3) can be driven at fixed cycle times. The degree of mixing is then defined by the ratio of the cycle times, if the switch-over time between the component feed lines (1, 2) is small compared to the cycle times. <IMAGE>

Title: Process and device for producing naturally cured, raw meat products
Inventor: LIESENFELD EMIL
IPC: A23B4/26
Filed: 1982-03-31
Abstract: The process and the device for producing naturally-cured, raw meat products are to make avoidable the hitherto conventional highly time- consuming dry salting of individual raw meat pieces with the frequent result of nonuniform salt distribution, oversalting and major expenditure of time. This object is achieved by the simultaneous treatment of a plurality of only lightly salted meat pieces located in layers one above the other in a pressure tank, which meat pieces are subjected to different pressure conditions by the pulsating pressure of a mechanically vertically moved lid with maintenance of certain time intervals, which pressure conditions after a short time cause an autogenous brine to emerge from the overall meat piece assembly, which brine dehydrates the meat and, after further time, reduces its initially relatively high salt content by losing salt to the meat.

Title: Method and system for measuring the oxygen concentration
Inventor: SAKURAI SHIGENORI
IPC: G01N27/407
Filed: 1982-07-16
Abstract: A method and a system for measuring the oxygen partial pressure in the exhaust gas of an internal combustion engine is described. A solid-electrolyte sensor tube is used which gives an electrical signal representing the oxygen partial pressure. The internal surface and the external surface of the sensor tube are each exposed to the atmospheric air and to the exhaust gas. If the exhaust gas comes from a gas mixture with an air/fuel ratio in the vicinity of the theoretical value, the electromotive force generated in the sensor tube is detected for emitting a signal and, if the gas mixture has an air/fuel ratio above the theoretical value, a constant voltage is applied between the internal and external surfaces of the sensor tube, and the limiting current flowing in the tube is detected for generating the electrical signal. In this way, a satisfactory measurement can be carried out within a wide range.
