Inventor: DUERIG HEINZ
IPC: E06B9/36
Filed: 1982-12-02
Abstract: The strip curtain has a plurality of glide elements which are guided by a curtain rod and connected with each other by separation-limiting devices. The free hanging curtain strips are suspended from vertical pivot axes with limited excursion. Operation of the pivot axis is by a pinion which engages a bead chain that is slidably guided by the curtain rod. The pinion is connected to the pivot axis by a worm drive, a slip coupling being provided between the pinion and the worm drive. The bead chain serves as common drive for producing pivotal movement and sliding movement of the curtain strips. The strip curtain is of simple construction and therefore reliable in operation and inexpensive and suitable for mass production.

Abstract: The present invention relates to a method for manufacturing zinc hydrometallur­gically from zinc-containing starting materials. The method comprises one or more leaching stages, one or more solution purifying stages and one or more electrowinning stages for recovering metallic zinc from the leaching solution obtained. The method is operating with a closed solution circuit. A predeter­mined part volume of the solution obtained in the electrowinning stage or stages is withdrawn and concentrated by evaporation so as to precipitate any magne­sium and manganese present in the part volume in the form of metal salt crys­tals. The precipitated crystal mass is separated from the residual liquid phase. The liquid phase in this manner purified with respect to magnesium and manga­nese can be recycled to the leaching process or utilized for some other purpose. When the process is carried out in a sulphate environment, the solution obtained in the electrowinning stage or stages is concentrated to a sulphuric acid concen­tration of at least 60% by weight.The precipitated crystal mass, which has but a small volume, may be dumped to no disadvantage. In accordance with a preferred embodiment, the crystal mass is re-dissolved in a small quantity of water, thereby enabling practically all the zinc content to be recovered in metallic form, by electrowinning.

Inventor: DIEMEER MARTINUS BERNARDUS JOH
IPC: G02F1/35
Filed: 1991-01-22
Abstract: The invention relates to an integrated optical polarisation splitter based on the mode filter principle, in which the asymmetry, necessary therefor, of the waveguides is obtained by using a polable glassy polymer as optical waveguide material, which material is polarisation-sensitive in the poled state and is not, or virtually not polarisation-sensitive in the unpoled state. A Y-shaped optical waveguide pattern 8 of polable glassy polymer comprises a continuous optical waveguide formed by the optical waveguide sections 8.1 (incoming) and 8.2 (outgoing) in which the polymer is in the unpoled state and an outgoing optical waveguide section 8.3 which connects to said optical waveguide at an acute angle and in a tapered fashion and in which the polymer is in the poled state. Since the poled material is also electro-optical, an electric field, for example generated between electrodes 2 and 10, can still correct any small deviations in the asymmetry. Advantages are simple production, with relatively high tolerances, and a short integration length of the component. <IMAGE>

Granted: 2000-08-22
Abstract: A  method and apparatus for conditioning an aluminum billet for extrusion from an extrusion press.      The billet is first heated above the solutionizing temperature fox the MgSi phases in the aluminum matrix, then the billet is cooled below the solutionizing temperature to an adequate hot working temperature.      Preferably, a temperature gradient is created along the length of the billet wherein one end of the billet is at or above the hot working temperature and the other end of the billet is cooled to a temperature below the hot working temperature. Thereafter, the billet is placed into the extrusion die, the hot end adjacent the die and the cool end adjacent the ram of the extrusion press. The billet is then extruded producing an extruded product with uniform properties along the length of the product with minimal defects such as tearing or hot shorting.

Title: Compact, high efficiency heat exchanger for a fuel-fired forced air heating furnace
Inventor: SHELLENBERGER TIMOTHY J
IPC: F28D1/06
Filed: 1990-11-09
Granted: 1994-03-29
Abstract: ABSTRACT OF THE DISCLOSURE        A  compact,  high efficiency  heat  exchanger  for a fuel-fired forced air furnace has horizontally spaced apart inlet   and   outlet   manifold   structures   which   are innerconnected by a horizontally spaced series of vertically serpentined, relatively small diameter flow transfer tubes.          Larger diameter inlet flow tubes are positioned beneath the balance  of  the  heat  exchanger,  extend  parallel  to  the transfer tubes, and have upturned discharge ends connected to the underside of the inlet manifold.  The heat exchanger is configured so that its total vertically facing peripheral surface  area  is  considerably  larger  than  its  total horizontally   facing   peripheral   surface   area,   thereby significantly reducing undesirable outward heat loss through the vertically  extending furnace housing  side walls upon burner shut off and increasing the overall efficiency rating of the furnace.   To reduce the manufacturing cost of the heat exchanger its components are assembled using a weldless fabrication process which includes swedging the tubes to the manifolds and forming each manifold from two sections which are edge rolled and crimped together.

Title: Method for handoff in a mobile radio communication system
Inventor: ISRAELSSON PER VIKTOR
IPC: H04W36/30
Filed: 1991-02-18
Granted: 2001-02-13
Abstract: The invention relates to a method in connection with handoff from a first base station (1) in a mobile radio communication system, in which method the signal strengths from a set of base stations (1) surrounding a mobile station are measured in the latter. When handoff is considered to be motivated, the signal strength vector formed by the measured signal strengths is correlated with stored characteristic signal strength vectors associated with the first base station (1).      If the correlation between measured signal strength vector and one of said stored characteristic signal strength vectors exceeds a predetermined correlation level, handoff is commanded to a predetermined second base station (2-7) in the set having acceptable but not the highest signal strength in the measured signal strength vector, or is the handoff procedure interrupted and the connection between the mobile station and the first base station (1) maintained.

Title: Stabilization and control of surface sagd production wells
Inventor: EDMUNDS NEIL
IPC: E21B34/16
Filed: 1993-05-26
Granted: 1996-11-12
Abstract: A method is provided for the stabilization and control of the two-phase flow of hot fluid containing water issuing from the top of an upwardly rising conduit or riser of a horizontal oil-production well. The fluid enters the bottom of the riser at a temperature higher than the saturation temperature of water at the conditions prevailing at the top of the riser. A first mass rate flow controller is coupled to a mass rate flow detector at the top of the well for controlling mass flow at a substantially constant rate over a short time interval. Signals indicative of the optimal flow rate for the process are input to a second controller. The second controller adjusts the mass flow rate setpoint of the first controller. The second controller has a time constant significantly longer than that of the first controller. Thus, the mass rate of hot fluid is controlled at a substantially constant mass rate over the short term, thereby stabilizing two-phase flow, and is adjusted over the longer term to control the flow of fluid at an optimal rate.
