Title: Material moisture content measurer using drying and weighing principle - applying HF power in frequency range to heat sample mainly dielectrically and keeping effect of phase angle low
Inventor: POLTE EVELYN
IPC: H05B6/54
Filed: 1991-01-23
Abstract: The sample (1) is placed in a narrow, rectangular cuvette-like test tube (2). The tube is located in the homogeneous portion of the e.m. h.f. field of a parallel plate type capacitor. The sample is dried out on the principle of dielectric heating. One capacitor plate (3) is at earth potential while the other (4) is connected to the h.f. generator via a cable (5) and plug (6). The loaded test tube is continuously weighed until the end of the drying process by being suspended over or placed by a post on a weighing cell without direct contact to the capacitor plates. The capacitor and test tube are placed in a Faraday cage (9) mounted on a receptor plate (10) for placing at earth potential. The upper part of the Faraday cage is in the form of an outlet cover (11) which is lifted off to change the sample and through which the water vapour can escape. During the measuring process the cover is galvanically coupled to earth. ADVANTAGE - Short drying time. Low power requirement and temp. loading of sample. Simple handling, making possible automatic series of measurements.

Title: Control for distribution of electric audio signals to connected loudspeakers - comprises electrical circuit with specific output sides for each loudspeaker connected via integral impedance correction
Inventor: RUF-KLOOS ELMAR
IPC: H04R3/12
Filed: 1991-02-11
Abstract: For each loudspeaker specific output sides (Ausgang 1-5) are connected via an integral impedance correction (L-Regler 1-5 with measurable resistance band) and corresp. relays (relais 3/4, 5/6, 7/8, 9/10, 11/12) in series connection with an impedance corrected controlling appts. on the input side. In order to operate one loudspeaker alone with full volume possibility, it is appropriate that the output side of the speaker (Ausgang a) by by-passing its impedance correction (L-Regler 1) is connectable via a relay (Relais 1/2) with the control appts. If the alternative arrangement is required, whereby only one loudspeaker is to receive the full volume via its output (Ausgang 1), then the impedance correction (L-Regler 1) is by-passed and the electrical audio signals are fed via the first relay (Relais 1/2). The circuit is so formed that each pair of loudspeakers connected to the control appts. receives its own volume adjustment. ADVANTAGE - For the distribution of audio signals to several loudspeakers, overcoming the hitherto experienced disadvantage whereby all speakers received the same volume level.
Patent DE-4105129-A1 (DE)
Inventor: KROEDEL BERND DR
IPC: C10F5/00
Filed: 1991-02-15
Abstract: The invention concerns a process for drying hydrous solid fuels, in particular raw brown coals, in a drying container of a heat-generating plant. The aim of the invention is to achieve substantial reduction of the CO2 emission per useful effect unit by reduced use of fossil energy carriers; the devices for drying raw brown coal are to be connected to the heat-generating installation in such a manner that the energy of the exhaust vapours is fully utilized. According to the invention, this is achieved by virtue of the fact that the drying container is heated directly by a saturated steam circuit of the heating boiler of the steam-generating plant, the dust-free exhaust vapours under average pressure are fed to a heat supply line and the exhaust vapour condensate is used, following chemical processing, to supply water to a heating plant and/or a heating network.

Title: Sepn. of prim. and sec. pats in dental prosthetic - comprises forming an oxide tube by contacting liq. sec. metal with a reactive oxide of the metal
Inventor: WALL GISELHER DR
IPC: A61C13/20
Filed: 1991-03-17
Abstract: Sepn. of the prim. and sec. parts in a dental prosthetic infusion technique comprises contacting the liq. sec. metal with a chemically reactive covering layer (I) (which is several times the wall thickness) in a special casting channel, spontaneously forming an oxide `tube' which leads to effective sepn. of prim. and sec. parts after cooling and demoulding. (I) can be (A) an individual oxide of the sec. metal or (B) an oxide of at least one of the sec. metals not naturally occurring as a foreign oxide, but which gives rise to the sec. metal oxide by reaction in the casting mould atmos. If (A) is used (I) is made from heavy metal oxides e.g., V, Nb, Ta, W, Mn, or Fe; a filler e.g, Cr (III) oxide, AlPO4, BPO4 or ZrSiO3, and a wetting agent. If B is used the (I) consists of stable oxides such as those of Al, La, Ti, or Zr or Hf, and a fluoride either complex (Na hexafluoaluminate or K hexafluozirconate) or simple (MgF2). ADVANTAGE - Leads to good prim./sec. item sepn. even in shapes with sharp edges and corners. Overcomes heat corrosion problems, ignition tendencies in easily oxidised metals, and neutralises the physical aggressiveness of certain (esp. Co) alloys.

Title: Compact portable vulcanising press for joining conveyor belts in situ - has upper heated platen uniformly loaded e.g. by hydraulic cylinders from crossbeams flexibly mounted on frame to allow deflection
Inventor: KERK UWE DIPL ING
IPC: B30B15/00
Filed: 1991-07-29
Abstract: Separate heater plates (5) are contained in a box-like upper platen (12), which is flexibly suspended from crossbeams (6) which are connected by an upper frame (9) allowing vertical movement at least equal to the max. theoretical deflection of the crossbeams (6). The lower platen (4) is rigidly mounted on crossbeams (3) and the pairs of crossbeams (3,6) are held together by tie-bolts (11). USE/ADVANTAGE - In-situ joining of, esp. rubber, conveyor belts, pref. forming endless belts. Vertical movement of the upper platen w.r.t the upper crossbeams permits the platen to deform, independently of the crossbeams, giving uniform moulding pressure on the belt (1) to be joined. Assembly time and labour is reduced. Loose connection of the crossbeams to the upper frame (9) avoids excessive loading of the frame, which can be made lighter for handling. Lateral positioning of the crossbeams by the frame avoids uneven loading and pressure on the belt due to manual placing.
Patent DE-4128337-A1 (DE)
Inventor: PLANTHOLT MARTIN DR
IPC: H04N9/79
Filed: 1991-08-27
Abstract: The letterbox process is considered in order to introduce a 16:9 large screen format compatible with existing television standards. The 4:3 receivers represent the 16:9 image information in a compatible manner with black stripes at the top and bottom edges of the image. In order to fill out the screen of a 16:9 receiver, additional information that allows an image with an improved quality to be obtained is transmitted in the black stripes of the compatible 4:3 transmission. In order to record PALplus signals on SVHS recorders, the additional information may be partially decoded. For that purpose, the additional information is demodulated before being recorded and is then recorded as basis band signals. Before being reproduced by a 16:9 receiver, the recorded additional information may go backwards through the decoding process carried out before recording, i.e. may be coded into an image signal containing additional information. In 16:9 television receivers, the additional information is then decoded again. Besides the disadvantage that represents the signal recoding effort in the recorder, the cascade coding/decoding worsens the signal-to-noise ratio in the signal. According to the invention, image signals containing partially decoded additional information recorded on SVHS recorders are directly supplied for further decoding to the 16:9 receiver and are not subjected to the corresponding partial decoding in the 16:9 receiver.
