The present invention provides a process for the preparation of an antacid material based upon magnesium aluminium hydroxide, wherein magnesium hydroxide and/or magnesium oxide is reacted in an atomic ratio of magnesium to aluminium of 1:1 to 3:1 with an aqueous solution of aluminium sulphate until the pH of the reaction mixture is from 4.0 to 8.0, whereafter water-soluble components are removed from the mixture in a known manner and the mixture is isolated and, if desired, dried or preferably the mixture obtained after centrifuging or filtering off is used without further purification and optionally dried.The present invention also provides pharmaceutical compositions containing an antacid material prepared by these processes, in admixture with a conventional pharmaceutical adjuvant.Furthermore, the present invention provides a method of combating hyperacidity and gastrointestinal diseases, which comprises administering an antacid material prepared by the above processes.

A process for the production of olefins from synthesis gas comprises a first synthesis stage in which a mixture of methanol and higher alcohols are formed from a synthesis gas comprising hydrogen and carbon monoxide. The catalyst for the first synthesis stage comprises the oxides of copper and zinc in intimate association with each other and a promoting compound selected from the group consisting of chromium, cerium, lanthanum, manganese, thorium, and an alkali metal. The materials from the first synthesis stage are separated into a gas phase and a liquid phase. Thereafter the methanol is separated from the higher alcohol fractions. The higher alcohols are then subjected to dehydration in a dehydration stage which comprises passing the higher alcohol fraction over an alkalized dehydration catalyst at a pressure in the range of 0.5-1 bar and a temperature in the range of 350.degree.-500.degree. C. Thereafter the olefins produced by the dehydration of the higher alcohols are separated into the olefinic and non-olefinic materials. Preferred dehydration catalysts include alkalized aluminum oxide and alkalized calcium phosphate.

The present invention teaches a method for applying an anti-reflection coating to solar cells whereby the coating is interdispersed among the cell's electrodes on the cell's junction surface. The method includes coating the solar cell's surface with an anti-reflection layer, selectively etching a pattern through the anti-reflection layer, which corresponds to the desired electrode pattern and electrolessly plating a layer of nickel onto the cell's surface.

A bonus award system for an automatic phonograph offers bonus pricing during bonus time intervals. Optionally operable means are provided for initiating bonus intervals in the absence or presence of record plays during random time intervals, which are determined in part by phonograph customer activity.
摘要:
A boring device is disclosed wherein a boring bit is rotated as it is advanced and supplied with water through a hollow interior to facilitate the boring operation. A rotary connection introduces water into the hollow boring bit and its support means from one side thereof through an apertured sphere secured to and revolving with the support means.

A diplexer for a reflector antenna includes a common circular signal waveguide to transmit and receive signals. The signal waveguide includes first and second ends with a common port provided at the first end. A waveguide arrangement is disposed coaxially relative to the signal waveguide in the region of the second end of the signal waveguide. A cylindrical coupler section is disposed between the first and second ends of the signal waveguide, and connects the waveguide arrangement to the common signal waveguide. In order to create a first and second coaxial waveguide port, the waveguide arrangement includes a first circular waveguide, an inner conductor is disposed inside, in which a first signal can propagate when the diplexer is operating, and a second circular waveguide, surrounding the first waveguide, in which a second signal can propagate at a lower frequency than the first signal when the diplexer is operating.

Unique context-based code enhancement of the core functionality of standard source code objects is performed at any position in the code. Desired insertion/replacement position(s) input by a user trigger the generation of a unique context for an enhancement. The unique context is based on characteristics of the code in the standard source code objects, such as the statements proximate to the insertion/replacement position(s). The unique context is associated with one or more extension source code objects that, when integrated into the existing source code at the insertion/replacement position(s), will provide the enhancement. At compile-time, the unique context used to unambiguously locate the insertion/replacement position(s). The extension source code objects can include industry or customer extensions, add-ons, plug-ins, and the like.
摘要:
A method, system, and computer program product for managing a plurality of antennas on user equipment. A connection status module is configured to monitor the plurality of antennas for a data packet of a plurality of data. A control module is configured to power more than one of the plurality of antennas to measure signal quality in response to receiving the data packet. The signal quality comprises a power level of each of the plurality of antennas and a correlation of the plurality of antennas. An antenna quality module is configured to determine whether the correlation of the plurality of antennas is greater than a threshold in response to the connection status being active.

Plastic parts are held by a holding device in a position for transfer to a receiver. Each part has a wall with a pierceable wall region that is accessible from one side, and the holding device is provided with a needle. With the part in the transfer position, the pierceable wall region is pressed against the needle, so that the needle penetrates the pierceable wall region and the wall is secured to the needle. The holding device may be a magazine type with multiple sockets for holding corresponding parts on needles.
摘要:
A rotary encoder device for scanning a rotatable shaft includes a microgenerator circuit, which converts the kinetic energy of the shaft into an electrical voltage, and a monitoring circuit, which is designed to output an error signal that indicates a malfunction of the microgenerator circuit. The error signal is issued when the electrical voltage meets a predetermined criterion with respect to a reference threshold.
