Patent DE-3334408-A1 (DE)
Title: Process and apparatus for better heat utilisation and lower SO2 emissions in heating plants
Inventor: LURZ KLEMENS DIPL ING
IPC: F23L15/04
Filed: 1983-09-23
Abstract: By the connection in series, according to the invention, of diverse heat exchangers for heating the combustion air, the return water of the heating plant and the use water, and also finally for reheating the cooled flue gases, the latter are cooled to the greatest extent. Not only an optimum heat utilisation, but also a minimum SO2 emission is aimed at. By the special construction and arrangement of the heat exchangers, very good heat transfer values and a low space requirement are attained, so that the overall plant becomes relatively cheap and can be built in without difficulties into existing heating plants - even those without acid-resistant chimneys. The good heat transfer according to the invention is achieved by high gas speeds and precise flow guidance of the gases; the usability of chimneys which are not acid-resistant by slight reheating of the flue gases after the separation of acid.

Filed: 1983-12-27
Abstract: A manually operable protection circuit breaker having a latching mechanism 6 for unlocking by means of a magnetic and/or bimetallic trip device, which latching mechanism 6 consists essentially of a pivoting lever, which is supported in the switch housing 2 such that it can rotate, and of an unlatching lever which interacts therewith, the pivoting lever 17 transmitting the pivoting movement of the handle 4 to a contact arm 13, the unlatching lever 18 being acted on by the magnetic and/or bimetallic trip device 7, 8, and having a latching point for a transmission bracket 26 which acts like a knee joint between the handle 4 and the latching mechanism 6, is characterised in order to improve the latching properties in that the unlatching lever 18 is constructed as a lever which is located parallel close to the pivoting lever 17, is supported on a separate rotation axis 19 which is arranged on the pivoting lever 17 at a distance from its axis 16, and is supported by means of its central region on a contact projection 22 which is fixed to the housing and is arranged at a distance from the axis 16 of the pivoting lever. The transmission bracket 26 is guided, by means of its end on the latching mechanism side, in a longitudinal groove 29 in the pivoting lever 17, and the latching point is constructed as a latching tab which, during the switching-on pivoting movement of the pivoting lever 17, projects with a reducing level of superimposition into the movement path of the transmission slide 26 and releases said movement path during the tripping pivoting movement of the unlatching lever 18. <IMAGE>
Patent DE-3407011-A1 (DE)
Title: Spark plug for internal-combustion engines
Inventor: BENEDIKT WALTER
IPC: H01T13/52
Filed: 1984-02-27
Abstract: A spark plug is proposed for internal-combustion engines, which is used for the reliable ignition of fuel-vapour/air mixtures, especially also for the ignition of weak fuel-vapour/air mixtures and at the same time is supplied with voltage pulses from a conventional ignition system. The spark plug contains an insulator in a sealed manner in a tubular metal housing, which insulator surrounds the centre electrode and a capacitor which can be discharged via the ignition spark gap; a preliminary spark gap is additionally preferably accommodated inside the insulator, which preliminary spark gap makes it possible to charge the capacitor to high voltage and to release the stored energy to the ignition spark gap in the event of electrical breakdown. According to the invention, at least two opposing electrodes are arranged at the same distance from the end section of the centre electrode on the ignition side; as a result of the high-energy starting phase of the ignition spark of such a spark plug, ignition sparks simultaneously jump across between the centre electrode and all the opposing electrodes, which ignition sparks together form a relatively large hot surface. Spark plugs according to the invention are particularly suitable for modern internal-combustion engines having precise fuel-vapour/air preparation and suchlike exhaust gas preparation. <IMAGE>
Patent DE-3408272-A1 (DE)
Title: Valve timing gear in an internal combustion engine
Inventor: PIESBERGEN H MICHAEL
IPC: F01L1/44
Filed: 1984-03-07
Abstract: The invention relates to the charge cycle control in internal combustion engines. The problem of accommodating control elements and/or valves in the combustion chamber is essentially solved in that only one valve is arranged in the working or combustion chamber, whilst the exhaust and refilling of the gases is performed upstream of this one valve, that is outside this heat-affected zone. The possible uses of the invention are in the internal combustion engine sector and include the internal exhaust gas recirculation in the control of the charge cycle. The one valve, arranged in the combustion chamber, functions as inlet and exhaust valve, around which exhaust gas and fresh gas flow alternately so that thermally it is not as highly stressed as existing exhaust valves. The valve B (dual-valve) shown in Fig. 1 assumes the control function without high pressure and thermal stressing; at the same time it must not form a hermetic seal like the single valve H in the combustion chamber. The control function of the dual valve B may also be assumed, for example, by an "Aspin" rotary slide valve system. <IMAGE>

Patent DE-3416744-A1 (DE)
Title: Method for the operation of a pressure regulator of a vehicle brake system with brake pressure sensors
Inventor: MAURER FRANZ PROF DR ING
IPC: B60T13/66
Filed: 1984-05-07
Abstract: A reference value element (23), actuatable by means of a brake pedal (24) and at least two pressure sensors (17, 18) serving as actual value elements are to be assigned to the pressure regulator (25) of the vehicle brake system (2). These measure brake pressures which prevail in individual wheel brake cylinders (5, 6) which can be acted upon by way of brake pressure control valves (7, 8). The wheel brake cylinders are divided between the lefthand and righthand wheels of the vehicle. So that the brake pressures and hence the brake forces are identical both left and right, display errors of the pressure sensors (17, 18) are automatically corrected. For this purpose a control and correction device (21, 22) is inserted between the pressure sensors (17, 18) and the pressure regulator (25). This device controls the brake pressure control valves (7, 8) in such a way that at least one and the same pressure acts simultaneously on all pressure sensors (17, 18), determines correction values on the basis of pressure-dependent signals from the pressure sensors and a calibration variable and in normal operation of the vehicle brake system performs signal corrections and feeds corrected signals as actual values to the pressure regulator (25). Brake forces of precisely the same magnitude both left and right have the advantage that the vehicle, for all pressure inputs, can be kept in a desired traffic lane with manageable steering wheel movements. <IMAGE>

Title: Device for the removal of a detonator cap from a cartridge case
Inventor: WOLFF DIETER DIPL ING
IPC: F42B33/04
Filed: 1984-08-01
Abstract: Particularly for those who shoot for sport, it is advantageous if they can determine the power charge of their ammunition themselves in order to be able to match its intensity to their type of weapon and to their own individual wishes. Cartridge cases which have been fired are therefore refilled with firing powder by the user, and are made reusable. However, the detonator cap (21) of a cartridge case (15) must be renewed for this purpose. A device is provided for this purpose which has a retaining chamber (14) of the shape and size of the cartridge case (15), in a housing (11). The retaining chamber (14) can be closed by means of a detachable guide bush (26) in which an impact bolt (28) can be moved in a sliding manner and which projects into the cartridge case (15). If the cartridge case (15) is filled with a fluid, such a high pressure can be built up in the interior of the cartridge case (15) by striking against the impact bolt (28) that said pressure is transmitted via openings (18) in the base of the cartridge case (15) to the detonator cap (21) and releases said detonator cap (21) from its anchorage in the cartridge case (15). The detonator cap (21) and the fluid then pass into a trough (25) which is arranged under the housing (11). <IMAGE>
