Patent EP-0004058-A1 (EP)
Inventor: VAN DER MAAS ROBERT E
IPC: F28D20/00
Filed: 1979-03-05
Abstract: A heat storing fireplace including a fire-box (14) surrounded by a heat storage medium which is either an enclosure (18) containing a material (20) having a high specific heat such as sand or gravel or a large number of heat conducting bags containing a high specific heat material. Exhaust gases are conveyed from the fire-box (14) to an exhaust outlet (24) by several conduits (22) extending through the heat storage medium in a circuitous path in order to transfer heat from the exhaust gases to the heat storage medium. Heat is further distributed through the storage material by a heat conducting lattice (26) fastened to the conduits (22) and extending through the storage medium in a circuitous path. Combustion air enters the bottom of the fire box (14) through a combustion air inlet jacket (28) surrounding the exhaust outlet (24) in order to simultaneously prewarm the combustion air while thermally insulating the exhaust outlet (24) from its support structure. A draft is created through the fire-box (14) by an exhaust fan (32) mounted in the exhaust outlet (24). Although the heat storage medium is primarily heated by burning fuel in the fire- box (14), it may also be heated by either an electric grill or solar heat exchanger embedded in the heat storage medium. The upper portion of the storage medium is covered by a ventilating plenum (38) which allows heat to escape from the enclosure (18). The plenum (38) has a pair of ventilated I sidewalls (40,42) separated from each other by a baffle (44). A fan (48), which may be thermostatically controlled, is positioned in an opening in the baffle in order to selectively produce air flow through the plenum (38). Heat in the storage medium may also be utilized by placing a hot water heating heat exchanger in the storage medium.

Abstract: A tuned viscous torsional vibration damper comprises an annular hub member (10) adapted for attachment to a shaft which, in use, is subject to torsional vibration. An annular inertia member (24) is wholly located within a closed annular chamber carried by the hub member and is journalled for rotation relative to the hub member (10) with its radial side and circumferential surfaces disposed in close spaced, face to face relation with opposing surfaces of the chamber. A viscous fluid is contained between the opposing surfaces in shear relation. The hub (10) has a plurality of teeth (42) which project radially inwardly into the annular chamber (20) and into respective circumferential gaps between adjacent, radially outwardly projecting teeth on the inertia member. In order to provide the damper with a plurality of discrete gas springs effective between the hub and inertia members, the circumferential spaces on the two sides of each hub tooth (42) communicate directly with respective angularly spaced, radially inwardly extending bores (46,48) in the hub member which contain respective volumes of gas forming said gas springs

Abstract: Aminosäurenfraktionen unterschiedlicher Zusammensetzungen werden durch fraktionerte Filtration zu verschiedenen Zeiten nach Neutralisieren der Hydrolysate gewonnen. Bei der Neutralisation eines Proteinhydrolysates kristallisieren die schwer löslichen Aminosäuren mit unterschiedlichen Geschwindigkeiten aus. Die erste Fraktion, die unmittelbar nach der Neutralisation ausfällt, ist an Leucin angereichert, und die späteren Fraktionen nach Kristallisationszeiten von mindestens 3 Tagen sind an Tyrosin und Cystin angereichert. Zur Gewinnung von L-Tyrosin wird die tyrosinreiche Fraktion bei einem pH-Wert von 10-11 gelöst, filtriert und das Tyrosin bei einem pH-Wert von 8,5 - 10, ausgefällt. Diese Lösung wird auf einen pH-Wert von 3,0 - 6,0 eingestellt und das ausgefällte Cystin abgetrennt. Die leucinreiche Fraktion wird in Säure gelöst, durch Zusatz von Oxydationsmitteln das Methionin oxydiert und ein Rohleucin bei einem pH-Wert von 1,0 - 2,0 ausgefällt wobei der Gehalt an Isoleucin in der Lösung vorzugsweise auf 1,0 - 1,5 % eingestellt wird. Zur Extraktion von Leucin, Isoleucin, Phenylalanin und Tyrosin wird eine mit Kochsalz gesättigte Lösung der Hydrochloride dieser Aminosäuren mit einem mit Wasser nicht mischbaren Alkohol, extrahiert. Durch Waschen des Alkoholextraktes mit Wasser kann der Anteil an Valin und Tyrosin weiter reduziert werden. Zur Abtrennung von Phenylalanin und Tyrosin wird eine neutrale Lösung, die Hydrochloride dieser Aminosäuren enthalt über einen schwach basischen und über einen stark basischen Anionenaustauscher geleitet. Durch Eluieren des stark basischen Anionenaustauschers mit einer Salzsäurelösung können das Phenylalanin und das Tyrosin vom Ionenaustauscher entfernt werden. Das Eluat wird konzentriert, dessen Salzsäuregehalt auf 20 - 25 % eingestellt, Natriumchlorid bei 70 - 90°C abgetrennt, und das Phenylalaninhydrochlorid durch Kühlung auskristallisiert.

Inventor: MILZ ARTHUR
IPC: F04D29/42
Filed: 1980-03-28
Abstract: The disclosure relates to a rotary pump especially for corrosive liquids including an impeller rotating in a working chamber. A spirally wound duct leads from one surface of the working chamber to the outlet pipe of the pump. The upstream end of the duct obliquely enters the working chamber, whereby the end portion of the duct is laterally open towards the chamber and forms a channel in the wall of the chamber. The duct winds helically around the rotation axis of the impeller, having an inside wall at a progressively decreasing radial distance from said rotation axis and a progressively increasing pitch when viewed in the direction of the flow. A feature is the provision of the wound duct in the form of a helix as an open groove formed on the outer surface of a solid stator body and closed by an encompassing casing. A further feature is the provision of a relatively loose, elongated drive shaft from a motor to the pump impeller disposed within a guide tube and a circumferential clearance between the shaft and the tube for leakage flow of liquid being pumped to lubricate the shaft wherein a bypass port is provided in the guide tube for return of the leakage flow upstream of a restriction in the clearance. The restriction increases pressure in the clearance to dampen lateral oscillation of the shaft in the tube. No seals are used for the shaft thereby precluding the tendency of seals to stick during prolonged rest periods.

Abstract: A scanning arrangement for an infra-red imaging device in which a column of I.R. detectors, and similarly a column of L.E.D.'s, scans a field broadside to produce a band of parallel line scans, a number of such band scans being provided to cover the field. Each band scan is performed by a respective mirror facet of a rotating polygonal drum, the facets being tilted at slightly different angles to provide the band displacement. Non-uniformity of the column of I.R. detectors or the L.E.D.'s or the interconnecting channels tends to produce the same pattern of non-uniformity within each band. This is overcome according to the invention by periodically tilting the drum by a random fraction of a bandwidth so that on successive occasions a particular element of the field is processed by different detector / L.E.D. channels.
