Title: Heat exchanger for a condensation water heater
Inventor: UCKELMANN WINFRIED
IPC: F24H8/00
Filed: 1988-12-06
Abstract: A water heater has a heat exchanger which is arranged in the waste-gas duct of a burner (3) within a common housing (1) and consists of a tube bundle (4). Arranged at the outlet of this tube bundle (4), which is connected to the combustion chamber (2) and through which waste gases flow, is, at a distance, a distributing plate (5) penetrated by openings (6), the distributing plate forming the top boundary of a condensate collector (7), to which a waste-gas pipe (9) and a condensate discharge (8) are connected. The openings (6) of this distributing plate (5) extend over an annular peripheral region and are designed with greater density and/or size in the region further from the waste-gas pipe (9) and closer to the condensate discharge (8) than in the diametrically opposite region closer to the waste-gas pipe (9). The overall cross-section of these openings (6) is smaller than the clear overall cross-section of the tubes of the tube bundle (4), so that the flow resistance is increased by the distributing plate (5) and the temperature of the waste gases is reduced. <IMAGE>
Patent DE-3843742-A1 (DE)
Title: Heat magnet in the form of a machine for generating, transporting and using heat from water vapour
Inventor: SCHOLZ BRUNO P O DIPL ING
IPC: F25B1/04
Filed: 1988-12-24
Abstract: The patent, which is designated as a heat magnet using the method of cold water vapour, employs a flow turbine for transporting vapour and heat, and for the purpose of liquefying the vapour and of releasing the heat utilises the centrifugal force and the impulsive (impact) force of the vapour, which is bound up therewith, owing to the steep curvature of the condensing pipes. All the processes in the machine take place in a vacuum, so that the energy expended for the turbine is very low. Since water requires a high heat of evaporation (vaporisation) for purposes of evaporation, it also dissipates a large quantity of heat when being liquefied, with the result that relatively high temperatures can be reached.

Patent DE-3918471-A1 (DE)
Title: Method and device for storing and controlling the movement sequence of a camera
Inventor: KUS HELMUT ING GRAD
IPC: G05B19/35
Filed: 1989-06-06
Abstract: In controlling the movement sequence of a camera there is the difficulty that the cameraman must specify a specific movement curve between a start position and a finish position by hand. A method and a device are demonstrated for storing and controlling the movement sequence of a camera, which can carry out movements by means of a motor-adjustable mounting device, especially a camera trolley or the like, at least one start point and finish point being able to be stored and the camera being movable from the start point to the finish point in an automatic travel. In this case it is proposed to store the position values between start point and finish point during a learning or sample travel together with associated time intervals from the beginning of the movement from the start point, and to repeat the stored location/time curve during the automatic travel, at least in sections.

Title: Coffin made of recycled waste paper - using paper machine with lacquer coating
Inventor: KIONTKE DORIS
IPC: A61G17/007
Filed: 1989-07-14
Abstract: It is suggested to make coffins not of precious wood but of recycled waste paper. If papermache is used, a thickness of 1.5 cm is believed to be adequate. After pressing to shape, the coffin would be coated with an environment-friendly lacquer. The outside of the coffin could be left plain or carry ornamental patterns for better effect. ADVANTAGE - This would save the forests and also lessen the burial costs, since the National Health Service of many countries has stopped the contribution to the burial costs.
Patent DE-3925399-A1 (DE)
Inventor: RITTER GUENTER DR ING
IPC: B01D53/02
Filed: 1989-08-01
Abstract: The invention relates to a process for working up coke which is loaded with heavy metal and has been doped with sulphuric acid before loading. It is the object to permit large amounts of flue gas of a waste incineration plant to be freed from heavy metal in such a way that only a small amount of coke loaded with the heavy metals is obtained and can be disposed of simply and in an economical manner. To achieve this object, the invention envisages a procedure in which the coke loaded with the heavy metal from the flue gas of the waste incineration plant is passed through a reactor (1) which has at least one desorption zone (7) and is heated within the desorption zone (7) to temperatures of about 500 DEG C. For desorption of heavy metals, the coke is heated in the reaction zone (7) for a period between 10 and 15 minutes and is treated during this time with an entrainment gas (10). The entrainment gas takes up the heavy metals released during heating of the coke. The loaded entrainment gas (16) is passed, with the supply of air (23), through a stationary bed of coke (24), which is likewise doped with sulphuric acid. This coke (24) adsorbs the heavy metal from the loaded entrainment gas (16) until a high adsorption rate of the order of between 15 and 35% is reached. After reaching the adsorptivity, the coke (40) considerably loaded with heavy metals is disposed of separately. Only relatively small amounts of this coke (40) have to be disposed of and may be placed in a landfill without particular expense. <IMAGE>

Title: Fuel injection valve for compression ignition engine - can be used either with self-lubricating or non self-lubricating fuel
IPC: F02M47/04

When the fuel is self-lubricating the valve has a single flexible diaphragm (3) with the outer edge of the diaphragm (3) attached to the valve body (4), and the inner edge attached to the valve needle (5). The valve needle is held in the valve seat (7) by the combined effect of the spring (8) and the control pressure in the control chamber (11). The valve is opened by the pressure in the fuel chamber (6) from fuel delivered by the pump. When the fuel is not self-lubricating the valve has two flexible diaphragms (3) with high pressure oil delivered to the chamber (10) between the diaphragms. USE - Fuel injection valve for compression ignition engine.

Inventor: SCHILLER JOERG DR
IPC: G01N3/40
Filed: 1989-10-17
Abstract: In the process for testing the hardness of mass-produced parts (32) with low mechanical reactance, a hardness testing device is used having a rod-shaped resonator (22), which has a Vickers penetration body (24) at its free end and a device for optically measuring the impressions, and thus permits hardness measurement by the ultrasonic contact impedance method (UCI) and also the optical measurement of the same impressions. In the process: an impression (38) is made on each of two or more hardness comparison plates for calibrating purposes and subjected to both UCI and optical measurement; the factors for a high-grade correction function for the UCI measurement and an at least linear correction function of at least the first grade for the optical measurement are found from the values obtained for the frequency shift and from the geometrical measurement of the impression and the known hardness of the comparison plate concerned; impressions (38) are made on a reference mass-produced part and UCI and optically measured and, from the ratio of the optical and UCI measurements obtained per impression, a correction factor is obtained; finally, the other mass-produced parts (32) are measured on as far as possible the same co-ordinates on the surface.
