Abstract: In one of the methods, connecting elements made by using concrete are produced by first pouring a fluid mortar, on the inside of a wall (1), into openings (5) of a template (2), with the addition of an adhesion promoter. A bell- or disc-shaped casting mould, which is filled with earth-moist concrete and is centred by the openings, is then placed upon this fluid mortar. The form elements thus produced can be stacked for hardening, with the interposition of thin plates, and subsequently joined to form form-element halves, for example by adhesive bonding. Modified methods produce the form elements by using dumbbell-shaped connecting elements made with the aid of axially separated mould halves. Form elements produced according to the method permit numerous modifications. <IMAGE>

Title: Frekvenslinearisert, mikrobölgeopererende spenningsstyrt oscillatorkrets
Inventor: POELKER JAMES
IPC: H03B5/18
Filed: 1991-02-07
Abstract: En spenningsstyrt oscillator (10) har forbedrete frekvensllnearlserlngskarakterlstlka. En radiallinje,. (flosshatt) skivegeometri (32,44) i forbindelse med en varaktordiode (31) er anbragt 1 en bredbånds kambølge-lederoscillatorkrets (11) for å frembringe en frekvenslinearisert spenningsstyrt oscillator. En anordning med negativ resistans er anbragt fordypet i kambølgelederen og er koaksialt koplet med en impedans-omformer (33) til kambølgelederhulrommet. Den foreliggende oppfinnelse anvender en skiveresonator (32) i en kambølgeleder til å omforme mlkrobølge-impedansen for et ikke-RF genererende element, en varktordiode (31) til verdier som gir forbedret spenningsstyrt oscillator avstemningsllnearitet.Skiveresonatoren eller radiallinjen er plassert over varaktordioden. Radiallinjen omformer mikrobølge-impedansen av varaktordioden til en ny verdi som så koples inn i kambølgelederkretsen og deretter til den RF genererende dioden (24). Kretsimpedansen, som er en funksjon av varaktorspenningen, virker til å linearisere frekvens i forhold til spenning karakteristikken for dioden. En sammenligning av operasjonen av kretsen med og uten radiallinjen/avstemningsskiven viser en 13:1 forbedring i frekvenslineariteten. Eksperimentelle resultater viser at kretskonfigurasjonen ifølge den foreliggende oppfinnelse er ideell for bruk i mikrobølge og millimeterbølge spenningsstyrte oscillatorer som krever en naturlig linearitet mellom frekvens og spenning ettersom den spenningsstyrte oscillatorens frekvenslinearitet er den kritiske faktor ved faselåst sløyfeopptreden, er den særlig egnet for bruk i mikrobølge og millimeterbølge-radar eller kommunikasjonssystemer som er frekvensvekslende.

Abstract: 1,059,410. Drying cylinders. WARTSILA-YHTYMA OY WARTSILA-KONGERNEN AB. March 18, 1964 [March 19, 1963], No. 11373/64. Heading F2U. In a rotating steam-heated drying cylinder for drying paper and pulp webs, wherein steam is introduced through an inlet pipe 15 and condensate is removed by syphon pipes 23 connected to an outlet pipe 10, the inlet pipe 15 feeds a single longitudinal or, as shown, several equally spaced adjustable nozzles 21 which extend over substantially the entire cylinder drying width and discharge steam in a direction opposite to that of the cylinder rotation at high velocity so as to obtain an effective heat transmission to the cylinder shell 2 and loosen the rimming condensate. The cylinder is mounted by trunnions 5, 6 integral with the cylinder ends 3, 4. The internal surface of the shell is machined rough or grooved to increase internal surface area. To regulate the drying effect across the cylinder the nozzles 21 are adjustable or closable by pneumatic or hydraulic membrane or plunger servomotors controlled outside the cylinder when the machine is running, or, as shown, by needles 22 when the machine is stopped. When the nozzles are closed at some part the condensate forms an unbroken ring locally preventing effective heat transmission. The nozzles are arranged on a longitudinal duct 20 connected to branch pipes 19. The branch pipes 19 and the syphon pipes 23 are respectively connected to compartments 13, 14 of a divided chest 7 which is stationarily supported by a pipe 8 and the outlet pipe 10 in bearing housings 9, 11. Alternatively, the chest 7 may be supported from outside the cylinder at one end only, its other end being supported by a bearing inside the cylinder, thereby providing for steam inlet and condensate outlet through the same trunnion. The inlet pipe 15 is connected to the compartment 13 through an injector 16, 17  by which remaining uncondensed steam may be re-circulated, to reduce pressure, through holes 18 in the pipe 8. Alternatively, the remaining steam may be led away with the condensate for use with reduced pressure parts of the system.

Filed: 1984-09-12
Abstract: There is disclosed a new process for the conversion of the organic components of sludge, particularly sewage sludge, to produce useful, storable, energy-containing oil products, apparatus for carrying out the process and a control process for optimisation of the process temperature. The sludge preferably is mechanically dewatered to about 20-25% solids by weight and thermally dried to about 90% solids by weight. The resultant material is comminuted and heated in the apparatus of the invention to at least 250°C in a heating zone in the absence of oxygen to generate a gaseous atmosphere containing volatiles; this atmosphere is then removed, scrubbed of H<sub>2</sub>S and NH<sub>3</sub> if required, and passed preferably in countercurrent flow in a heated reaction zone in intimate contact with the «devolatilized» sludge solids from the heating zone, again in the absence of oxygen, at a temperature of at least 280°C, resulting in catalysed vapour phase oii-producing reactions. The oil vapours are carried out by the gas flow and condensed. The preferred apparatus moves the sludge solids cocurrent with the heating zone atmosphere and countercurrent with the reaction zone atmosphere. In the reaction zone the conveyor not only moves the comminuted sludge along but lifts it and drops it through the gaseous atmosphere for the preferred intimate contact. Preferably the sludge is examined repeatedly by differential scanning calorimetry to generate a thermogram which has been found to reveal immediately the optimum temperature for operation of the reaction zone, and also the anticipated oil yield from the sludge.
