Title: Process for the continuous extraction of peat and apparatus for carrying out the process
Inventor: TOLPA STANISLAW
IPC: C10F7/00
Filed: 1996-09-05
Abstract: An extracting agent, preferably sodium hydroxide solution containing 0.2 to 0.7% of NaOH, is allowed to flow from bottom to top through a bed of the comminuted peat and is removed above the bed, at a rate such that the flow remains laminar and the extract obtained remains essentially free of entrained particles of the peat to be extracted. If appropriate, fresh extracting agent is added and the extracting agent is allowed to flow once more through the bed, preferably is recirculated several times. An apparatus for carrying out the process has at least one storage tank for the extracting agent (NaOH), at least one extraction tank (E) and at least one circulation tank (Z) for the extracting agent enriched with extract, feed pipes in which pumps (P) are arranged leading both from the storage tank and from the circulation tank (Z) into the lower pipe from each extraction tank (E), while the discharge pipe from each extraction tank (E) leads from its upper part and enters the associated circulation tank (Z).

Inventor: BAKER SAMUEL M
IPC: D21F7/08
Filed: 1999-03-16
Abstract: A multilayer porous fabric which comprises a porous core fabric (10) provided with hook means (11), and at least one layer of pre-needled nonwoven fibrous batt (12A,12B) attached by entanglement onto the hook means (11) by pressing the core fabric and batt together. The entanglement is sufficient to anchor the batt reliably to the core fabric, so that the multilayer fabric is ready for use without further processing. The porous core fabric may be formed by weaving or as an extruded sheet, with a plurality of suitably located hook means structures on at least one of its surfaces. The hook structures engage with and entangle sufficient fibers from the pre-needled nonwoven batt to provide adequate attachment preventing the batt from separating from the core fabric enabling the multilayer fabric to be handled before use, for example for installation in a papermaking machine press section. The batt is pre-needled to a desired density before attachment to the core fabric. In many circumstances, compressive loads applied to the porous fabric serve to enhance and improve the level of entanglement of the batt onto the hook means. <IMAGE>

Filed: 1995-01-09
Abstract: PURPOSE: To improve the detection accuracy of a motion vector by comparing the correlation of image signals of 1st and 2nd motion vectors and selecting an interpolation vector with higher correlation. CONSTITUTION: When an interpolation image 12 is inserted between two preceding and succeeding images, motion vector detection circuits 20, 21 provide a preceding vector 13 representing the movement from a preceding image 10 to a succeeding image 11 and a succeeding vector 17 representing the movement from the succeeding image 11 to the preceding image 10 respectively. Preceding and succeeding DFD arithmetic circuits 22, 23 obtain a preceding DFD value 26 and a succeeding DFD value 27 representing the correlation of image signals before and after the movement of a block Bi as to the preceding and succeeding vectors 13, 17.  Preceding and succeeding allocation circuits 30, 31 respectively convert the preceding and succeeding vectors 13, 17 into a before-interpolation vector 32 representing the movement of the block Bi from the preceding image 10 to the interpolation image 12 and an after- insertion vector 33 representing the movement of the block Bi from the succeeding image 11 to the interpolation image 12 based on an insertion ratio L and outputting the before- interpolation vector 32, the preceding DFD value 26 and the after-insertion vector 33, the succeeding DFD value 27 respectively in pairs. A comparator circuit 50 compares the correlation of the preceding DFD value 26 with that of the succeeding value 27 and outputs a selection signal 51. A vector selection circuit 60 outputs the vector 32 or 33 with higher correlation in DFD based on the selection signal 51.

Abstract: PURPOSE:To reduce standby time when double side transfer or superimposed transfer is carried out by setting standby positions of paper sheet guides in the middle of positions corresponding to the largest and the smallest paper sheets. CONSTITUTION:When an automatic double side device is used when superimposed transfer or double side transfer is indicated, a stop guide 38 and a side guide 37 are moved according to the size of a paper sheet being carried, and the end part of the paper sheet being stacked is arranged properly in a stack part 6.

A sensor 375 to regulate an initializing position of the side guide 37 is situated in the middle of a length in a direction orthogonal to a carrying direction of the largest size and the smallest size paper sheets. Thereby, when superimposed transfer or double side transfer is indicated, time necessary to move the paper sheet guides to a position corresponding to the paper sheet can be reduced.

Filed: 1981-01-08
Abstract: PURPOSE:To eliminate essentially the image interference in a UHF-VHF tuner device, by setting an intermediate frequency between 325MHz and 340MHz. CONSTITUTION:A television signal of the VHF or UHF band received by an antenna 1 is amplified by an RF amplifier 2 or 8, and the signal of the VHF band is supplied to a mixer circuit 3 and has the frequency converted into a prescribed IF signal in a range of 325-340MHz by the local oscillation signal from a local oscillator 4. Meanwhile, the signal of the UHF band amplified by the RF amplifier 8 is supplied to a mixer 9 and is converted to the same frequency as the VIF frequency by the local oscillation signal from a VCO10. This converted UHF signal is supplied to the mixer circuit 4 which is operated as a mere VIF amplifier at a UHF receiving time. Thus, the VIF frequency is set to a frequency higher than the conventional that to eliminate essentially the image interference.

Abstract: PURPOSE:To achieve a better flocculation with a simple control system overcoming any sharp change in the quality of raw water due to rainfall or the like by injecting a flocculant after the control of quantity of an alkali agent injected based on two  indicators of water quality that is the alkalinity of the raw water and the pH of a floculated water following the injection of the flocculant. CONSTITUTION:The alkalinity of a raw water 31 in a waterwell 4 is measured with an  alkalinity meter 35 and a corrected alkalinity Al1 is determined with an arithmetic  unit 37 from a chlorine injection rate DCl and an alkali agent injection rate DAl. An  alkali agent injection rate DAl1 is determined with an arithmetic unit 43 from the turbidity Tu measured with a turbidimeter 34 and the corrected alkalinity Al1. On the  other hand, the pH of a flocculated water is measured at the inlet of a floc formation  pond 6 with a pH meter 41 and an alkali injection rate DAl2 is determined from the  turbidity Tu with an arithmetic unit 42. The alkali injection rates DAl1 and DAl2 are  compared with a comparator and after the larger value is choosed as the alkali injection rate DAl, an alkali injection rate Al is obtained from the value and the flow rate  F of the raw water. The quantity CO of the flocculant injected is found from the  flocculant injection rate DCO determined from the turbidity Tu and the corrected alkalinity Al1 and the flow rate F of the raw water.

Title: Air mixing chamber for transporting powdered-coal of powdered-coal transporting facilities
Inventor: OHARA SEIJI
IPC: B65G53/22
Filed: 1985-01-09
Abstract: PURPOSE:To improve the precision in weighing the powdered coal by installing an ejector for the transport air into a mixing chamber and installing a valve and a pressure adjustor into a vacuum break pipe arranged onto the outer periphery of the mixing chamber, thus eliminating the pressure applied into a rotary feeder and a bellows pipe. CONSTITUTION:In the transport of powdered coal, the inside of a mixing chamber 10 is made vacuum by the jetting-out of the transport air supplied from an ejector 11, and the degree of vacuum is detected by a pressure adjustor 14, and then a valve 13 is opened to a prescribed opening degree, and the atmosphere is a little absorbed through a vacuum break pipe 12, and the degree of vacuum can be lowered to a prescribed value. Since the pressure in the mixing chamber 10 becomes a little vacuum during the transport of powdered coal, a rotary feeder 6 is not applied with pressure, and also a bellows pipe 5 is not applied with pressure, and the necessity of making the inside of the bellows pipe 5 airtight is obviated. Therefore, the resistance for the tilt of a disc in a coal weighing machine 4 is reduced, and the correct tilt of the disc can be measured by a load cell, and the precision in weighing the powdered coal can be improved.
