Patent EP-0024557-A1 (EP)
Inventor: ENGEL WILLIAM KARL
IPC: F03C1/30
Filed: 1980-07-29
Abstract: In a pump or fluid motor (11, 11 a, 11b) having a closed chamber (57) in which cylinders (38) orbit and reciprocate, leakage and cooling fluid which accumulates in the chamber (57) is formed into a rotating annular volume by centrifugal effects and exhibits a higher pressure in the region where the cylinders (38) move radially inward and closer together than in the opposite region where the cylinders (38) move outward and further apart. Power wastage from drag torque, turbulence and heat generation is reduced by scavenging the accumulated fluid from the chamber (57). Internal recirculation of the scavenged fluid from the high pressure portion of the annular rotating volume back to the low pressure portion is avoided by communicating the drain passages (68, 68a, 68b) with only a limited relatively high pressure sector of the rotating volume of fluid.

Abstract: A xerographic copier includes a control system to reduce the density of over-dense developed images after a period of non-use. After such a period, a signal from timer 84, in conjunction with a copy request signal, is effective to operate flip-flop 104 to cause low voltage photoconductor charging and to initiate a toner density test on a developed test patch on the photoconductor. Toner replenishment is at this time inhibited by an output from flip-flop 108. As copying continues, when a low density image is detected, as indicated by a low toner signal, the charging voltage is stepped up in stages by flip-flops 119 and 102 until the normal working voltage is reached. At that time, normal toner replenishment is started when required.

Abstract: A quick connect-disconnect electrofluidic junction assembly for simultaneously transferring fluid and electrical energy from respective sources of supply. The assembly includes a female terminal with an internal receptacle one end of which is open and surrounded by a peripheral wall. An electrical contact is positioned inside the housing and spaced apart from the open end. A fluid passage extends through the housing and communicates with the receptacle. A male terminal includes a hollow connector body which is adapted to be push-fit into the receptacle through its open end, with an electrical contact on its forward end adapted to mate with the electrical contact in the housing. A sealing element is located around the periphery of the body for providing a fluid-tight seal between the body and the interior wall of the housing when inserted therein. A fluid channel extends through the body between its forward end and the peripheral sealing element, so that fluid may be received from the receptacle, and then pass on through the body along with electrical leads whereby both an electrical and fluid connection can be made to the assembly.

IPC: C21D1/64
Filed: 1981-07-25
Abstract: When tempering metal parts in a bath which is stirred to increase the cooling effect, such a strong relative motion of the bath with respect to the parts is created during at least the formation phase of a vapor film on the part, that the evacuation of heat out of the parts is effected, in an average, with a thermal flux density of at least 0.75 MW/m<s2>s. This tempering power is maintained until the surface of the larger cross section part has reached the stable temperature of the bubble vaporization; thereafter, the stirring of the bath is slowed down. To implement said method, an installation is used having a bath tank associated to devices for introducing metal parts to be tempered into the bath and for stirring the bath. Nozzles (24) directed against the parts are connected to a pressure tank (18) filled with the bath liquid (2) under the control of valves. When the tank is filled, it is under a gas pressure and it discharges the liquid at a high speed towards the nozzles (24) during a short and controlled period of time (t).

Abstract: In a process for the separation of elements by chromatography in which a front zone and a rear zone are present in front of and in rear of an adsorption band of elements, a high column efficiency can be attained by developing the adsorption band of elements without causing the entry of a main eluent having a relatively high concentration into the front zone. According to the present invention, elements can be separated into individual species not only in a high state of purity but also in a high state of concentration, so that the productivity of elements may be extremely increased as compared with that of conventional methods. In addition, according to the present invention, the amount of eluent employed is remarkably small as compared with that in conventional methods. Therefore, the present invention is very advantageous for the separation of elements from an industrial standpoint.

Abstract: The invention relates to a device for extracting moisture from a space (1) and transferring it to a second space (2) by means of a loop circuit (5) containing a hygroscopic liquid. In the first space (1) moisture is absorbed in the hygroscopic liquid and in the second space (2) the moisture is evaporated from said liquid. Sometimes the evaporation process is so intensive that the hygroscopic liquid becomes overconcentrated, so that the flow in the circuit (5) is impeded by crystallization of the dissolved substance. According to the invention this problem is solved by the use of a concentration controller (25), which maintains the concentration below a specific desired value.

Abstract: A self standing marine riser is provided which comprises a base (4), a riser column (1), a flexible joint (7) between the base (4) and the riser column (1), and means for providing a loose coupling between the top of the riser column and a vessel, rig or platform (2) on the surface above the location of the riser. The riser column comprises an upper column section (11) which includes at least one buoyancy chamber, and a lower, relatively slender column section (6). The riser (1) includes, or is adapted to support, at least one conduit for the conveyance of a fluid (e.g. oil or gas) or a control line. The buoyancy provided by the upper section (11) of the riser column is preferably variable, and this facilitates the connection and use of the riser. The riser may be used for drilling operations or for production operations. By employing a riser in accordance with the invention, it is not necessary to use large riser tensions in order to maintain the position and structural integrity of the riser in deep water and rough weather.
