Filed: 1996-05-03
Abstract: In the process for the continuous firing of ceramic pipes (30), the pipes (30) lie on two support bars (34, 35) running in the longitudinal direction (28) of the furnace (26). Said support bars (34, 35) form a plurality of descending sections (36, 37) down which the pipes (30) can roll. To each descending section (36, 37) is allocated a stop (40) which is provided at the end of a descending section and is fitted across the length (28) of the furnace (26). On rolling down the descending section (36, 37), the pipes (30) acquire sufficient kinetic energy, for them to be redirected across the longitudinal direction (28) on striking the stop (40).

Title: Ice beer production by ice growth with controlled recirculation
Inventor: WIESNER MAREN
IPC: C12C11/00
Filed: 1996-09-13
Abstract: Production of ice beer involves fermenting wort, yeast being added to the new or green beer, and terminating the fermentation is arrested on reaching the desired degree. The yeast is removed and the beer is cooled to a temperature in the boundary region between solid and liquid phases. Ice crystals resulting from cooling are removed and the ice-free beer is stored at the same temperature, checking the alcohol content and maintaining uniform storage conditions. The novel feature is that cooling and ice separation are carried out in a common stage, preceding maturation, in which the ice crystals are grown on a separator. Also claimed is equipment to carry out the process, employing a liquid cooler (1) in the path between a fermentation vat and a storage tank. This has heat exchanger plates, constructed as ice separators.

Title: Measuring process for paint penetration of paper
Inventor: GRUENER GIESELHER
IPC: G01N13/00
Filed: 1996-11-15
Abstract: The process uses sensors (2,3) placed on opposite sides of the vessel (1) holding the liquid (8). The paper sample (7) is held on a support bar (6) mounted on a slide (5) running on a slideway (4) above this, so that the end of the support bar is in the liquid.  To avoid distortion of the measurement, caused by the effects of air space between paint and paper following rapid insertion of the sample, or by changes in the rheology of the liquid during a prolonged measuring process, the support bar is dipped very quickly in and out of the liquid, using a motor or pneumatic drive, immediately before insertion of the paper sample. This movement, over a fixed time period, ensures greater accuracy.

Patent DE-19701642-A1 (DE)
IPC: F16H47/04
Filed: 1997-01-18
Abstract: The invention concerns a continuously variable transmission comprising: a mechanical power branch and an electronically controlled hydraulic power branch which can be adjusted by means of a swash plate (7); a summarizing transmission; and a multi-stage gearbox with hydraulically operated, force-locking shift elements (11 - 14). The shift signals of the shift elements (11 - 14) are generally triggered when a shift or synchronizer speed is attained. This is followed by a response or reaction time and an adjusting time, until the shift elements (11 - 14) are engaged, which results in long clutch shift processes. According to the invention, the response and engagement times of the shift elements (11 - 14) are compensated by a control unit.

Patent DE-19705524-A1 (DE)
Title: Pressure injection moulding maintaining planar front in melt flow
Inventor: HETTINGA SIEBOLT
IPC: B29C45/00
Filed: 1997-02-13
Abstract: In this novel method, plastic is conducted into the moulding cavity forming  the plastic object, in a controlled manner. After forcing and sealing the dies together,  plastic is injected at given rate and pressure. Its leading edge forms a planar surface. A sensing system detects a magnitude, providing a sign of departure from planar front progression into the cavity. A sensor detecting this magnitude, signals the injection device that plastic shall now be injected in accordance with a control algorithm for injection pressure. The cavity is then completely filled and the moulding is hardened. Preferably the rate of injection is raised, preferably in proportion to the flat area of the melt front. This may occur after a given portion of the plastic has been injected into the cavity. The injection unit is not signalled as described, until a given portion of the plastic has been injected into the cavity. The injection unit has a linear transducer monitoring the quantity of injected plastic. The injection and its acceleration is controlled by a  central processing unit, connected to the transducer. These may provide a signal to initiate a pressure based injection algorithm, determined from the injection rate. The pressure in the cavity is used as a sign of departure from a planar front. A pressure sensor is used. A variety of developments on this theme are described, based on the above principles, in which various other physical measurements are used to indicate the departure from the planar front condition.

Title: Manufacturing method of semiconductor memory device with capacitor
Inventor: CHAO FANG-CHING
IPC: H01L27/108
Filed: 1997-05-14
Abstract: The manufacturing method involves forming on the substrate a first insulator, overlaying the transfer transistor and forming a first conductive layer. At least the first insulator is electrically coupled with one of the drain and source of the transfer transistor. A stack layer is formed on a second insulator and a third insulator is formed on the stack layer sidewall. A fourth insulator is formed on the second and third insulator surface. The third and fourth insulator and insulator located below the third insulator until the first conductive layer surface are removed to form an opening. On the stack layer and first conductive layer surface is formed a second conductive layer, which fills the opening approximately.  The second conductive layer is patterned, to separate the portion located above the stack layer. The stack layer is then removed and insulator located below the stack layer until the first conductive layer surface is removed. The first and second conductive layers are patterned, to make one end of the second conductive layer connect to the upper surface of the first conductive layer. The first conductive layer constitutes a trunk-type like conductive , and the second conductive layer constitutes a branch-type like conductive layer, and the first and second conductive layer constitute a storage electrode of the storage capacitor. The second insulator is then removed and a dielectric is formed on exposed surface of the first and second conductive layer, forming one dielectric. On one surface of the dielectric a  third conductive layer is formed to constitute an opposed electrode of the storage capacitor.
