Patent CA-2032348-A1 (CA)
Inventor: KROLOPP ROBERT K
IPC: H04W88/06
Filed: 1990-12-14
Abstract: A process for use in a radiotelephone that has multiple telephone numbers for use in different cellular radiotelephone systems. The numbers are stored in number assignment modules (NAM's) with its corresponding system identification code. The process compares a received system identification code with the ones in memory (103). If a match is found, the radiotelephone user is prompted to select the new telephone number (104). If the new number is not selected or the identification code is not found in memory, the radiotelephone becomes a roaming unit and enters an idle state (107) waiting for an incoming call.

Abstract: The invention relates to a method for determining and regulating the liquid metal level in a metallurgical vessel, especially an open-ended die of a casting plant. In order to provide a method in which the liquid level can be determined and regulated in a simple and reproducible manner, it is proposed that inert gas be introduced into the molten metal at a certain freely selectable point within the vessel, that the flow rate and absolute pressure of the inert gas introduced be measured, that the absolute pressure measured when the zero value of the flow rate is exceeded be recorded and the actual value of the distance of the surface of the liquid from the point at which the inert gas is introduced be determined from the difference between the absolute pressure and the pressure acting on the surface of the liquid, that the difference from a predetermined setpoint value be determined from the said distance ascertained and fed as an electric actuating signal to an actuator for regulating the liquid metal level and/or the quantity flowing out or withdrawn from the vessel.

Title: Spiral filtration module with improved cleanability and operating efficiency
Inventor: CHANG JIKUO
IPC: B01D63/00
Filed: 1991-05-15
Abstract: Abstract A cleanable ultrafiltration device (10) and method of making same is the subject of the present invention.  The device (10) comprises a housing (12) for receiving a feed stream of a liquid to be filtered and a membrane cartridge (14) disposed in the housing (12) for separating the feed stream into con-centrate and permeate.  The cartridge (14) is disposed within that housing (12) in spaced relationship to accommodate the flow of the feed stream around the periphery of the cartridge (14) along its length.  A plastic netting (26) is typically used for the cartridge/housing spacer (25).  A potted end seal (28) blocks the flow of the by-pass feed stream at the outlet end (18) of the cartridge/housing assembly and forces all of the feed stream through the cartridge (14).  This approach improves operating efficiency by elimination of the wasted by-pass flow associated with the prior art design, while main-taining module cleanability.

Inventor: EDEN RICHARD C
IPC: H01L25/10
Filed: 1991-08-28
Abstract: The disclosure is directed to an improved circuit and method which utilizes a plurality of generally planar diamond substrate layers.  Electronic circuit elements are mounted on each of the substrate layers, and the substrate layers are disposed in a stack.  Heat exchange means can be coupled generally at the edges of the substrate layers.  In a disclosed embodiment, a multiplicity of generally planar diamond substrate layers and a multiplicity of generally planar spacer boards are provided.  Each of the substrate layers has mounted thereon a multiplicity of electronic elements and conductive means for coupling between electronic elements.  In general, at least some of the electronic elements on the substrate layers comprise integrated circuit chips.  The substrate layers and spacer boards are stacked in alternating fashion so that spacer boards are interleaved between adjacent substrate layers.          Each of the spacer boards has a multiplicity of electrical conductors extending through its planar thickness to effect coupling between electronic components on the substrate layers on its opposing sides.  The extremely high thermal conductivity of diamond permits adequate heat removal from the defined three-dimensional circuit structure by heat exchange means that do not substantially interfere with electronic element density, with vertical interconnect density, or with the desire for small physical size.

Title: Integrated optical head structure
Inventor: GELLER FRITZ
IPC: G11B7/12
Filed: 1991-09-17
Abstract: ABSTRACT     Semiconductor optical head structure for accessing storage locations on an optical storage medium, such as an optical disk, for writing, erasing, and reading of information, including tracking-error detection and focusing-error detection systems. Both error detection systems are optical and electrical separated to avoid any mutual interferences of the error signals, and all optical elements of the optical head are integrated on one chip. The focusing-error signal is generated by deflecting a separate beam (20A) out of the optical head (15) and focusing it onto the surface (12) of an optical disk (11) and detecting the reflected portion (20B) thereof. The separate readout and tracking-error signal is generated employing light beam (21A) which is focused to the center of the pits (10) of a track and detecting the diffracted portion (21B) thereof. Focusing-errors can be reduced by actuating the head perpendicular to the disk (11) using coil (22). If a tracking-error is measured the head can be moved using actuator (17), until the error is minimized. The required optical head can be grown on a compound semiconductor material, such as GaAs, using planar fabrication technology.

Abstract: ABSTRACT       A centrifugal film bioreactor useful for processing both shear sensitive and shear requiring or tolerant cells. A liquid phase is directed upward in a guide tube to rotating truncated conical surfaces which transport the liquid phase across their surfaces. After leaving the conical surfaces, the liquid passes through a gaseous phase and may contact the wall of the fermentation vessel and then combine with the downward moving liquid phase in the lower part of the fermentation vessel, where it circulates. The maximum entrainment of the gaseous phase into the liquid phase occurs while the liquid phase is passing through the gaseous phase. Different configurations of guide tube propellers and fermentation vessel, allow for processing of different shear tolerant cells .

IPC: F25B25/02
Filed: 1992-02-19
Abstract: HIGH EFFICIENCY ABSORPTION CYCLE OF THE GAX TYPE                ABSTRACT OF THE DISCLOSURE         A high-efficiency, enhanced, generator-absorber heat exchange (EnGAX) cycle, particularly useful in gas-fired, air-cooled absorption heat pumps, increases the heat output of the absorber in the temperature overlap range with the generator to equal the heat usable by the generator.  This is accomplished by establishing a solution pathway from a portion of the absorber in the temperature overlap region to a portion of the generator in order to increase solution flow in the high temperature regions of the absorber and generator.  Further improvements in cycle efficiency are obtainable by increasing the operating pressure of the absorber.

Title: Float valve for container-filling systems, in particular systems for filling electric drive batteries
Inventor: ROVER DANIEL
IPC: H01M50/609
Filed: 1991-05-02
Abstract: The invention relates to a float valve (3) for container filling systems, especially for electrical traction battery filling systems, comprising a valve housing (10) that accommodates a valve chamber (11) and a valve head (31), the valve chamber being provided with a filling medium supply inlet (16) and an outlet (17) leading to a container, the valve head (31) being connected to the float via a stem and a float rod (35, 36, 37) and being movably disposed in a valve chamber (11) to open the inlet and the outlet (16, 17) and shut off the outlet (17).      To guarantee quick closing action also with low liquid pressures and to prevent dripping in the closed position it is proposed according to the invention that the filling medium be introduced first in a distribution chamber from where it flows into the valve chamber in a manner that it enters the valve chamber in the bottom area of the latter along the entire surface of the side walls and flows uniformly through the valve chamber. The valve head (31) rests in a recess (13) in the bottom of the valve chamber (11) and is for the most part outside the flow during the filling process. Only when it is lifted out of the recess (13) by the float, the valve head (31) is pushed into the closing position by the flow forces.
