Granted: 2000-02-22
Abstract: The invention at hand relates to a micro-filter disc based on kieselguhr, also known as diatomaceous earth, particularly for a complete sterilization of water. The micro-filter disc contains at least two kinds of silicately bonded kieselguhr at least one of which is pre-calcined and later burnt or sintered. The micro-filter disc has pore sizes in preferred magnitudes of 0.1 to 0.3µ whereby bacteria are mechanically and safely retained. A method is disclosed making possible the use of three kinds of kieselguhr and kaolin in connection with a careful drying and sintering thereafter. Thereby, it is possible to produce discs having diameters larger than 35cm and a thickness of 1 to 1.5cm. Such discs can be cleaned by way of rotating brushes slightly scraping off the discs. This enhances a simple construction of self-cleaning filter installations. The thus constructed filter installations require very little service and can be serviced by inexperienced operators.

Title: Method for controlling the thermal head drive
Inventor: YANAGISAWA SHIGEKAZU
IPC: B41J2/355
Filed: 1995-12-01
Granted: 1999-04-27
Abstract: The present invention provides a method and an apparatus for driving and controlling a thermal head used in a printing device, such as a tape printer, in response to the temperature variations of the environment and the thermal head. According to the present invention, in the printing operation of the tape printer, measurements are made of the initial temperature T1 immediately after the power is switched on, the temperature prior to printing T2, and the ambient temperature of the thermal head each time the thermal head prints T3 (i). If the temperaturedifference between the initial temperature T1 and the temperature prior to printing T2 is small, the duration of the current signals provided to the thermal head iscontrolled in accordance with the temperature prior to printing T2. If the difference is large, the duration is controlled in accordance with the initial temperature T1 to reduce the duration. If the rate of the increase in temperature during printing T3(i) is large, the duration is controlled in accordance with the initial temperature T2 to reduce the duration. If the temperature during printing T3(i) exceeds a temperature which indicates overheating, the printing operation is aborted. Thus, the present invention allows for controlling the thermal head drive by means of the ambient temperature which is not affected by the heat generationof the thermal head and in accordance with the thermal state of the thermal head.

Title: Process for producing granules
Inventor: STARMANS PETER J M
IPC: C05G5/30
Filed: 1997-04-14
Granted: 2005-03-08
Abstract: A process for producing granules from a liquid composition which includes the steps of applying the liquid composition onto solid particles of the same composition circulating in the granulation zone of a granulator, thereby causing particles to grow, discharging a stream of grown particles from the granulation zone, cooling this stream in a cooler, and dividing the stream exiting the cooler, in a size-sorting apparatus, into three streams of grown particles based on size. The stream of desired-sized particles is withdrawn for future use or processing, the stream of undersized particles is returned to the granulation zone and the stream of oversized particles is sent to a size-reducing apparatus for crushing, with the resulting crushed particles recycled back to the cooler located downstream of the granulator and upstream of the size-sorting apparatus.

Abstract: Insulating oil in electric power transmission devices such as a transformer is filtered for removal of accumulated water and carbon particles. The filter and circulation pump are usually located in a separate cabinet external to the transformer with circulation conduits connecting the filter, the pump and the transformer. To prevent or minimize environmental contamination by leaks or ruptures in the oil circulation conduits, oil flow within the pump suction conduit is monitored independently of oil pressure within the pump discharge conduit. A flow rate or discharge pressure below a predetermined minimum operates motor control relays to terminate the pump drive motor operation and transmit appropriate alarms.      Additionally, an accumulation of oil in the dry sump volume of a pump and filter housing also activates motor terminating relays and transmits an alarm. Simultaneous with disconnection of the pump drive source, the pump suction conduit is closed by a normally closed solenoid valve positioned in the line near the power transmission device.
Patent CA-2212569-C (CA)
Inventor: HARMATHY TIBOR ZOLTAN
IPC: A47K10/38

Granted: 2001-11-13
Abstract: This invention relates to a device, which offers a person the convenience of tearing off with one hand any length of a flexible sheet material, typically toilet paper or kitchen towel, from a roll at a line of weakness (perforation) in the sheet. The device consists of two main parts: a stable "cradle" and a movable "pallet." The cradle is made up of a back plate whereby it is fastened to a solid surface, two side plates between the roll is held, possibly a bottom plate on which (with the most practical embodiment of the invention) the roll rests, and a "lower jaw bar." The pallet is rotatably attached to the side plates of the cradle. It has two cross bars: the "upper jaw bar" and the "press bar." In preparing for use, the free end of the sheet material is passed through the gap between the upper jaw bar and the press bar of the pallet in such a way that the upper jaw bar lies above and the press bar below the sheet; then the roll is installed in the cradle. Pulling the free end of the sheet away from the roll will cause the upper jaw bar to lift away from the lower jaw bar, thus any length of the sheet material can be freely unwound from the roll. By shifting the direction of the pull toward the lower jaw bar, the pressure on the press bar will force the upper jaw bar against the lower jaw bar, and thus prevent further material from unwinding from the roll. Increasing the pull, any length of the material outside the press bar can be separated from the roll along a line of weakness in the sheet.
