Patent EP-0327574-B1 (EP)
Title: Echangeur de chaleur a plaques, ayant une structure a double paroi
Inventor: DAHLGREN ARTHUR
IPC: F28D9/02
Filed: 1987-10-19
Granted: 1994-04-13
Abstract: Dans une série de plaques (5, 6) d'échange de chaleur, chacune étant rectangulaire avec des orifices (7, 8, 9, 10) dans ses parties d'angle, des plaques alternées (6) sont entièrement obturées et coopèrent avec des plaques intermédiaires (5) pour définir deux groupes de passages allongés à travers lesquels s'écoulent les fluides d'échange de chaleur respectifs (A, B). Chaque plaque intermédiaire (5) n'est que partiellement obturée et définit avec une des deux plaques (6) adjacentes entièrement obturées une région communiquant directement avec l'atmosphère, l'obturation partielle consistant en des moyens d'obturation (7a, 8a, 9a, 10a) des orifices, interconnectant les paires respectives d'orifices en regard afin de former des canaux à travers lesquels les deux fluides (A, B) s'écoulent sans pénétrer dans ladite région. Les régions forment des chemins à travers lesquels toute fuite de l'un ou de l'autre fluide (A, B) peut s'échapper vers l'atmosphère, empêchant ainsi la contamination d'un fluide par l'autre.

Abstract: The method has optimised energy supply and energy switch-off and uses a heating characteristic line for controlling predetermined room air temperatures and support temperatures for room air and wall surfaces, as well as a rapid heating-up characteristic line for calculating the latest possible switch-on point for rapid heating up. The heating characteristic line and the rapid heating-up characteristic line are adapted automatically and both in the short term and in the long term to the heating installation, to the building and to the climatic conditions affecting the building. Control and adaptation are carried out using periodic measurements of the heating forward run temperature at the inlet and the heating return run temperature at the outlet of the heating circuit, as well as of the outside temperature. For buildings which consist of only one room, or for heating circuits which have at least one room, the static and dynamic thermal properties of which also apply for all other rooms, the additional use of a sensor for the room air temperature has the advantage of shorter running times of the heating circuit pump during the time when the energy is switched off and the parameters are adapted for the heating characteristic line during control of the fixed room air temperature.

Abstract: Aromatic compounds are alkylated with C20-C1300 olefinic oligomers by contacting the oligomers and aromatic compounds with an acidic catalyst to produce novel alkylated aromatic hydrocarbon compositions useful as lubricant basestock and additives. The olefinic oligomers used as alkylating agents are prepared from 1-alkene oligomerization in contact with a reduced chromium oxide catalyst on silica support. In one embodiment, the aromatic compounds are alkylated with a mono-olefinic HVI-PAO dimer which is prepared as a product or by-product from 1-alkene oligomerization using reduced chromium oxide on solid support. The alkylated aromatic hydrocarbons retain the unique features of the alkylating olefinic oligomer and exhibit high viscosity index and low pour point. The novel alkylaromatic compositions show improved thermal stability; also, the compositions are useful as lubricant additives for improved antiwear properties, antioxidant and other properties.

Said threshold value switch (34, 36) is of high resistance when the voltage applied thereto is smaller than its threshold value and of low resistance when the voltage applied thereto is greater than its threshold value. The threshold value of the threshold value switch (34, 36) is so set that it is greater than the voltage applied thereto in the receiving operating phase but smaller than the voltage applied thereto in the transmitting operating phase.

Abstract: A high voltage power supply comprises a transformer T1 having primary and secondary windings, a power generator TR1 for resonating with the primary winding to generate a sinusoidal waveform VC and a voltage multiplier (30) coupled to the secondary winding for developing a derived voltage VHV for driving a load. A switch is coupled to the primary winding for periodically supplying the primary winding with energy pulses to replenish load losses. An oscillator (40) generates a timing signal synchronized with the sinusoidal waveform VC. A regulator (20) synchronized with the timing signal controls the switch TR1 responsive to a signal indicative of variations of the derived voltage source. The oscillator comprises a capacitor C3 and a diode junction coupled in series with the primary winding. The diode junction DJ1 forms part of a transistor in a multivibrator. The timing signal comprises pulses substantially coincident with minimum amplitude peaks of the sinusoidal waveform VC. The pulses correspond to conduction of the diode junction. <IMAGE>

Abstract: A composting method and apparatus is disclosed for accelerated decomposition of organic matter. The organic matter is deposited into a chamber of a vessel. A ram moves through a relatively short stroke within one end of the vessel so that organic matter deposited in the vessel at one end may be moved through the chamber and discharged at the other end as a result of each successive charge of material pushing the preceding charge forward through the vessel by the action of the ram. The vessel includes a set of orifices in a floor of the chamber for introducing pressurized air into the vessel. During the normal composting operation, pressurized air passes through these orifices at a relatively low intensity to aerate the organic matter. At certain times during operation of the ram, a surge of pressurized air will be introduced into the chamber of the vessel through the orifices at such an intensity as to effect movement of the organic matter through the chamber with a ram force which is substantially less than the ram force required to move the organic matter absent the surge of air. This provides a substantially less dense mass of organic matter moving through the chamber of the vessel than would be produced without the delivery of the surge of pressurized air.
