Patent DE-19700141-A1 (DE)
Inventor: BARTUSCH WOLFGANG DIPL ING
IPC: H05B6/80
Filed: 1997-01-04
Abstract: In a baking oven (10) for the high-temperature treatment of materials with a relatively low dielectric loss factor (tan  delta ) by heating the material by absorption of microwave energy in a resonant chamber (16), a uniform energy intensity of the microwave field is to be achieved for example by irradiating the microwave energy over a broad band and/or by varying in time the frequency of the irradiated microwave energy. The resonant chamber (16) and the radiation source (13) are tuned to each other such that the relation: (V/ lambda <3>) .B>/= 20 is satisfied. V stands for the volume of the resonant chamber (16),  lambda  for the wavelength of the microwave radiation and B its band width. V/ lambda <3> equals at least 300 and the clear dimensions lx, ly and lz of the resonant cavity (16) in the direction of the co-ordinates x, y and z are approximately equal to the cubic root of V. The wall (161 to 166) of the resonant cavity is made of graphite and can be heated by a heating device (28) up to the temperature of the material to be treated. The heating device is arranged outside the resonant chamber, and a heat insulating envelope (38) encloses the unit of resonant cavity (16) and heating device.

Title: Boiler for low temperature heating
Inventor: NOHREN HARTMUT DIPL ING
IPC: F24H1/28
Filed: 1997-01-10
Abstract: The boiler has a combustion chamber (1) with a flue (2), in order to heat a secondary circuit water jacket (3), and has forward (5) and return (4) flow connections. The primary circuit is arranged in an annular space (6) around the perimeter of the combustion chamber, and is connected to the jacket. The annular space is much smaller than the jacket, and the wall (7) between them has two apertures (8,9). One of the apertures (9) is always open. The second aperture (8) is also always open, and in order to prevent returning cold water from flowing directly into the annular space, the return flow runs into the jacket in a region which is distant from the second aperture.

Patent DE-19720958-A1 (DE)
Title: Cooled combustion engine piston with walled piston ring grooves
Inventor: ULLRICH MICHAEL
IPC: F02F3/22
Filed: 1997-05-17
Abstract: The annular wall (3) and annular rib (4) facing this are both threaded (8,9) to accept the sheet metal ring part of the ring-containing wall. The cooled and slotted ring fits into grooves designed into the annular wall and the opposing rib, the slotted part of the ring being eased in with the aid of an entry ramp piece. Both the threads and the specified groove come in rectangular profile and the ring is held in place by a clamping effect, notably provided by punched tongue. Otherwise the ring itself is corrugated or undulated to the same effect. The height and depth of the rectangular profile of the respective threads lies between 0.5 and 2 mm, with a thread pitch of between 1 and 2 mm. The cooled and slotted ring has openings for the coolant, to be engaged by conventional hand tools. The ring is twisted into the threads so the sheet and points meet to close off the cavity (6) from below. The proposed grooves cancel out the slight axial play produced by the thread pitch, although an absolute seal is optional.

Title: Method for conveying water from vertical water borehole system
Inventor: TALLEY ROBERT R
IPC: E21B43/30
Filed: 1997-06-19
Abstract: The method for conveying water from vertical borehole system involves the vertical borehole (10) extending from the upper surface (11) to below in undersoil ground-water leads (12) along which a horizontal borehole of considerable length (30) is arranged passing by the vertical borehole. Water is pumped out of the vertical borehole which is, in the main, removed from the ground-water leads via the horizontal borehole. The horizontal borehole may have an outer end remote from the vertical borehole, and an inner end (36). The horizontal borehole may also have sections (31,33) and extend itself from the upwards to the upper surface, whilst the upper sections (31,33) may be sealed off at one position (35).

Patent DE-19729578-A1 (DE)
Title: Wire saw
Inventor: EGGLHUBER KARL DIPL ING
IPC: H01L21/304
Filed: 1997-07-10
Abstract: The wire saw has rotatably mounted wire guide rolls with a saw wire (37) wound around them so that two adjacent wire guide rolls bound a wire grid (39) with a definite width (B). One of the wire guide rolls is supported on an elongate carrier structure (7) with one end free and the other rigidly attached to the machine frame (6). One of the wire guide rolls is designed as a sleeve (2) which is mounted on a carrier roll (3) and has at least one axial bearing (16). This bearing ensures that the axial centre of the wire guide roll is not, or is only slightly displaced through axial expansion of the roll caused by heat. Also claimed is a method for axial adjustment of a wire guide roll bounding the wire grid. This is achieved with use of two axial bearings in the form of hydrostatic or aerostatic axial bearings which are supplied with the pressure medium at different rates.

Title: Ultrasonic printing head cleaning unit
Inventor: HUNCK WOLFGANG HEINRICH
IPC: B08B3/12
Filed: 1997-07-12
Abstract: The ultrasonic printing head cleaning unit carries out cleaning via the cavitation cleaning effect using sonic pressure built-up by a longitudinal wave field.
