Patent DE-3836661-C1 (DE)
IPC: F04F5/10
Filed: 1988-10-27
Granted: 1990-04-19
Abstract: Jet pipes of this type are used in particular for processing contaminated earth. High costs for the exchangeable parts result from wear and the period of inoperation. The object is to design the jet pipe in such a way that the periods of inoperation are reduced and the wear lessened. The jet pipe (1) has an inlet (2), a section (3) adjoining the latter and having outlet openings arranged about the inside of the tube in the circumferential direction, and a conical tube section (5) adjoining the section (3). The conical tube section (5) is designed as a tube insert which can be inserted separately from the section (3). <IMAGE>

Title: Keycard switch
Inventor: BOCKHACKER REINHARD
IPC: H01H27/00
Filed: 1993-10-09
Granted: 1995-02-23
Abstract: The invention relates to a keycard switch which is designed on the basis of a conventional electrical domestic installation push button. As a result of the capability to operate it by means of a keycard, it is used as an energy saving switch (main switch). Such switches are used in hotels where a keycard which is used to operate room door locks is available. In this way, after entering the room, the keycard is pushed into the further-developed installation push button according to the invention and remains there until the room is vacated, that is to say the keycard must necessarily be removed in this event. Any loads which are switched on are thus switched off. At the same time, it is essential to the invention that the conventional push button is provided with a special insertion device (plug-in device) which, even when installed as a flush-mounted unit, takes account of any compensation for wallpaper which may be required.
Patent DE-4337642-C1 (DE)
Title: Valve actuating device for an internal combustion engine
Inventor: PAUL MICHAEL DIPL ING
IPC: F01L1/26
Filed: 1993-11-04
Granted: 1995-02-09
Abstract: A variable valve timing gear for at least one inlet or exhaust valve E has a camshaft 4 with a low-speed cam 2, 3 and a high-speed cam 7. A first rocker arm 5 interacts with the low-speed cam 2, 3 and the valve E. A further rocker arm 8, 9 interacts with the high-speed cam 7 and can be coupled to the first rocker arm 5, as a result of which the valve is actuated according to the contour of the high-speed cam 7. The second rocker arm 8 is acted upon by a pre-loaded spring 20 in the direction of its cam 7. In order to reduce the friction between the second rocker arm 8 and the cam 7 in the low-speed range, the second rocker arm 8 can be arrested in its maximum lift position, so that it then comes in contact only with the tip of its cam 7. It is arrested by means of a piston 27, displaceably guided in the second rocker arm 8, which piston is capable of engaging by means of a spring 29 in an opening 28 in the fixed rocker arm axis 6 when the second rocker arm 8 is in its maximum lift position and which is forced out of the opening 28 by a pressure medium which is fed to a longitudinal duct 14 in the axis 6. <IMAGE>

Patent NL-1013648-C1 (NL)
Inventor: WILLEMSEN JOHANNES ALBERTUS HE
IPC: F28F1/06
Filed: 1999-11-23
Granted: 2001-05-28
Abstract: A heat exchanger raises the temperature of water which is subsequently to be used especially for showers and baths. The heat exchanger has a central inner passage (2; 152; 202, 252), and an outer passage (4; 104; 154; 204;254) which extends longitudinally in the direction of, but outside the inner passage (2; 152; 202, 252). The inner (2; 152; 202, 252) and outer (4; 104; 154; 204;254) passages are separated by a first wall (3; 153: 203; 253), and a second wall (5; 155; 205; 255) which delimits the outer passage (4; 104; 154; 204;254). The second wall (4; 104; 154; 204;254) has especially a profiled form. Preferred Features: The incorporation of a profiled outer wall to the outer passage maximizes the rate of heat transfer from the outer passage to the surrounding area. Further, the profile intensifies the heat transfer between the inner and outer passages, and reduces the time taken for the heat exchange to reach its maximum rate. The heat exchanger is positioned within a hot water storage tank. Following the shut-off of supply of heated heat-supply medium, the water which is subsequently to be drawn off cools more rapidly. The temperature of the water remains for only a short time in that range at which legionella bacteria can multiply. The water temperature recovers rapidly following re-introduction of heated heat-supply medium. Water which is to be drawn for especially washing purposes is held at the ready at a temperature below the 60 degrees C which is required for the survival of legionella bacteria, and is heated rapidly upon demand.

Granted: 2008-01-15
Abstract: Sap recovery from tree leaves or pine needles involves dielectric (D) introduced between high voltage electrode (E) and tree or growing plant at earth potential. The dielectric provides access for the electric field but prevents a short circuit occurring between the high voltage source and the leaves or needles of the tree or plant. The sap is accordingly withdrawn from a tree or plant branch (T). The configuration is preferably tubular and outwardly horn-shaped at its ends in order that the electric field at the outer ends is formed gradually.
