Abstract: The invention relates to a device for welding tile-shaped or web-shaped floor coverings of plastic laid adjacent to one another with a joint clearance with the introduction of a welding rod (36), softened by hot air, into a joint (47). Said device consists of a portable, motor-driven carriage (11) on the housing (12) of which two drive wheels (14, 15) mounted on a common axle (13) and a supporting wheel (16) are mounted, and of a hot-air fan (50) and a nozzle (19) connected to said fan and a feed wheel (35) for the welding rod. The nozzle (19) in this device is arranged fixedly on the housing (12) and lies jointly with the feed wheel (35) in a plane in front of the outer end face (37) of a drive wheel (15). By means of a device of this kind, the feeding of hot air can be directed selectively onto the interior of the joint and onto the strand-shaped welding rod. <IMAGE>

Abstract: Improved process for preparing cyclic acetals of 3-formyl-2-butenyltriphenylphosphonium chloride by acetalisation of 3-formyl-2-butenyl acetate with an aliphatic 1,3-diol, conversion of the 4-acetoxyacetal obtained into the corresponding 4-hydroxyacetal, Vilmeier chlorination to give the corresponding 4-chloroacetal and subsequent reaction with triphenylphosphine, which is characterised in that the first 3 reaction steps are carried out in an aliphatic or cycloaliphatic hydrocarbon or hydrocarbon mixture having 6 to 8 C atoms and the reaction with triphenylphosphine is carried out in an alkanol having 1 to 3 C atoms and/or in an aliphatic or cycloaliphatic hydrocarbon having 6 to 8 C atoms or an appropriate hydrocarbon mixture. The process becomes particularly advantageous if the conversion of the 4-acetoxyacetal into the 4-hydroxyacetal is carried out with an aqueous alkali solution and in the presence of phase-transfer catalysts and the first three or all four reaction steps are carried out in the same C6-to C8-hydrocarbon.

Abstract: Apparatus for growing cells or tissue  in vitro , which permits a concentration gradient of nutrients to develop through a permeable membrane to which a sample of tissue is attached. The permeable membrane is attached to the bottom end of a cell culture insert that in turn is supported by a flange connected to its upper end on the top of a well containing the nutrients. Restricted movement of the cell culture insert in the well may be facilitated by projections extending off the outer wall surface of the insert so as to avoid capillary action in the space between the well and the insert.

Inventor: ABRAMS STEVEN RICHARD
IPC: G06F17/50
Filed: 1993-12-21
Abstract: Beginning with a CAD specification of an object, the method and apparatus of the invention reduces the overall time to produce a shell of the object with a rapid prototyping machine. The reduction in time is achieved by interleaving the computation and the building tasks and by not requiring an explicit evaluation of a shell of the solid at the outset. The method is shown to operate with STL data, or with other CAD data, directly, and can also be employed to create non-planar objects, such as models of sheet metal parts that are represented only as surfaces. Furthermore, the method can be employed to produce a smooth outer surface even when employing polyhedral approximations to the surfaces of the object.

Abstract: Combustion facilities includes a combustion apparatus (1, 61) having a burner (5), a fuel control valve (16) disposed along a fuel feeding pipe (6), a air control valve (19) disposed along an air feeding pipe (9). An optical sensor (28) detects radiated light originated in combustion flame of the burner (5), and converts it into a first electric signal. The first electric signal is a composite signal consisting essentially of an intensity signal element reflective of the intensity of the detected light and an oscillation signal element reflective of fluctuation of the turbulent combustion flame caused by the air feeding to the burner. A sensor amplifier (27), which is connected to the optical sensor (28), extracts both the oscillation signal element and an intensity factor representative of a real intensity of the radiated light originated in only the combustion flame, from the first electric signal, and generates a second electric signal by dividing the oscillation signal element by the intensity factor. A combustion controller (36), which is connected to the sensor amplifier (27), applies frequency analysis to the second signal, and calculates "Oscillation Power" based on the result of the frequency analysis. The oscillation power is closely related to the excess air ratio to be controlled. The combustion controller (36) controls the air control valve (19) based on the oscillation power, separated from the fuel control valve (16).

Abstract: This invention aims to prevent an obstacle from being trapped between a vehicle window and a window frame. A supersonic wave f is emitted into a vehicle window W. A reflection wave i of the supersonic wave is received to decide whether the reflection wave i is one reflected from peripheral faces of a target to be detected or not. If the received reflection wave i is one reflected from the peripheral faces from the target, a driving motor M for the vehicle window W is stopped. Thus, when an obstacle contacts with the peripheral faces of the vehicle window, it is possible to previously prevent the obstacle from being caught by the window since a driving source for the vehicle window is stopped.

Title: Metal-air power supply and air-manager system, and metal-air cell for use therein.
Inventor: BENTZ R DENNIS
IPC: H01M12/06
Filed: 1993-03-12
Abstract: A metal-air power supply which provides improved control over air flow is provided. The reactant air and cooling air inlets are separate from one another and isolated from the exhausted reactant and cooling portions of the air flow. The reactant air flow is limited to a volumetric flow rate sufficient to provide from about 3 to about 10 times the stoichiometric amount of oxygen necessary to produce a predetermined level of current from the cell, and a total volumetric flow rate of air sufficient so that the cooling portion of the air flow has a volumetric flow rate from about 10 to about 1000 times the volumetric flow rate of the reactant portion of the air flow is provided. This limits the flow rate of the reactant air over the cathode, isolates the cooling air flow from the reactant air flow, and maintains the temperature of the metal-air cell at a low level without exposing the air cathode to an excessive air flow rate to reduce the likelihood of drying out the metal-air cells, reduce the exposure of the battery cell to contaminants, and minimize the effects of temperature on the vaporization of water within the cell. In a preferred embodiment, the power supply housing and the metal-air cell case form part of the air plenums. A substantially leak-proof metal-air cell is also disclosed.
