Title: Method and apparatus for adjusting the filling level in filling machines for vessels
Inventor: HARING FRANZ
IPC: B67C3/26
Filed: 1993-06-18
Abstract: Method and Apparatus for Adjusting the Filling Level in Filling Machines for Vessels Abstract The present invention relates to a method and an apparatus for adjusting the filling level in filling machines for vessels, wherein the filling level is measured with the aid of a probe immersed in the filling vessel and is adjusted in response to a signal from the probe.            To obtain information about the instantaneous filling level at any time, a continuous measuring signal which is substantially proportional to the filling level is produced by a probe. An elongated probe body is here immersed into the liquid of the vessel to be filled, with a plurality of measuring points being connected to an electronic evaluation means via a plurality of switching elements, and a ground contact projects into the vessel to be filled to the farthest degree.            A quasi-continuous signal curve can be implemented with this method through a plurality of measuring points, resulting in a time-dependent signal function S (t) from the gradient of which the filling speed can be derived at any time t.

Abstract: TITLE        CELL CULTURE PLATE WITH A SYSTEM FOR LATERAL DIFFUSION OF             MOLECULES THROUGH A BARRIER MEMBRANE                                ABSTRACT A cell culture plate with a system for lateral diffusion of molecules across a barrier membrane (Figure 1), comprising a base consisting of two or more flat-bottomed open-topped w?lls, denominated the reservoir wells, each containing one or more wells of smaller ??? (dif???? w?lls), likewise open-topped and sharing the same flat base, characterized in that each of the the diffusion w?lls communicates with the larger homologu? which houses it via one or several slits located in the lateral wall(s) of the diffusion well(s), and in that each slit is covered by a semipermeable membrane that permits the passage of soluble substances while retaining insoluble particles and cells; and a removable lid. The cells deposited in the diffusion well(s) may interchange their metabolic products with the corresponding reservoir well containing culture medium or other cells. The problem caused by other devices wherein the diffusion of substances occurs between a higher compartment (which usually contains the cells) and a lower compartment, separated by a barrier membrane, making difficult the microscopic observation of the cells and the manipulation thereof, is thus solved.  The field of application include various branches of biology, such as immunology, pha???ology, toxicology, microbiology and parasitology
Patent CA-2124621-A1 (CA)
Inventor: PARTRIDGE B WARING III
IPC: H04M11/00
Filed: 1994-05-30
Abstract: A method and apparatus for concurrent communication of analog information and digital information. In general terms, when the communication channel is viewed as a multi-dimensional space, the digital information signal is divided into symbols, and the symbols are mapped onto the signal space with a preset distance between them.  The analog signal, generally limited in magnitude to less than the distance separating the symbols, is converted to component signals and added (i.e., vector addition) to the symbols. The sum signal is then transmitted to the receiver where the symbols are detected and subtracted from the received signal to yield the analog signal components. The transmitted analog signal is recreated from those components. Both half duplex and full-duplex operation is available in accordance with this invention.
Patent CA-2127914-A1 (CA)
Inventor: FELDMANN FRITZ K
IPC: F42B12/06
Filed: 1994-07-13
Abstract: ABSTRACT   A fin stabilized subcaliber projectile is subject to aerodynamic drag during night along the trajectory to its target. Under this influence its velocity decays accordingly. For kinetic energy armor piercing projectiles its effectiveness depends primarily on the impact velocity at the target. The reduction of the aerodynamic drag and induced decay of the projectile velocity is the subject of this invention. The aerodynamic drag in supersonic flight is the sum of pressure and wave drag and skin friction drag of the various projectile components such as the slender projectile nose, the high fineness ratio cylindrical body and the fin assembly needed for projectile stabilization. An additive aerodynamic drag is induced by a section of threads or a group of annular grooves arranged on the cylindrical body of the subcaliber projectile engaging a mating configuration provided on the interior of the metallic base of the discarding sabot. To minimize the drag of the acceleration-transmitting interface, whether annular grooves or threads, its length has to be as short as possible and be determined by the force to be transmitted and the dynamic strength properties of the mating sabot. The latter are less than those of the high density, high strength projectile material such as sintered tungsten alloy or depleted uranium alloy and therefore are the basis for the structural design. Limiting the length of the structural interface will reduce its pressure and wave drag, in addition, proper placement of the structural interface on the cylindrical body of the projectile can reduce the skin friction drag. Locating the structural interface aft of the point where natural transition of the laminar boundary layer to turbulent boundary layer occurs and/or at a station immediately ahead of the fin assembly will provide maximum benefit from the low friction coefficient of laminar boundary layer. Projectile velocity measurements over a range of 2000 meters have demonstrated the effectiveness of the inventions by a substantial reduction of the velocity decay.

Abstract: A growth medium for a plant having roots comprises an upper compression resistant layer and a lower root development layer. The upper compression resistant layer comprises a compression resistant mixture of discrete inorganic particles and solid rubber particles.      The thickness and the amount of the solid rubber particles is sufficient to substantially absorb compressive loads which are applied to the top surface of the compression resistant layer. The compression resistant mixture has sufficient porosity to permit water to drain therethrough.      The lower root development layer comprises a mixture of discrete. inorganic particles and organic material. The size of the discrete inorganic materials and the amount of organic matter are selected to allow the capillary flow of water in the mixture of discrete inorganic particles and organic material. The organic material has a size sufficiently large to remain in the mixture against the leaching action of water passing through the root development layer. The distance between the top surface of the growth medium and the lower root development layer is sufficiently small to enable the roots of a plant to reach the lower root development layer.
