Patent SE-7602206-L (SE)
Inventor: LYNCH J F
IPC: F24F11/04
Filed: 1976-02-24
Abstract: A conduit with inlet and discharge ends respectively for receiving a supply of air under pressure and for delivering the air at a lower pressure has a cylindrical configuration and an eliptical butterfly type damper is disposed diagonally therein. The damper turns about an axis intermediate its diagonally opposite ends and the oncoming air stream thus impinges on the upstream face of the damper on opposite sides of the axis and creates a differential force, the said differential force tending to close the damper and constituting a first closing force. A second closing force for the damper is provided by a small bellows supplied with air through a small conduit from the downstream side of an orifice member disposed in the main conduit upstream of the damper. A second and substantially larger bellows serves to open the damper and a small conduit connects the said bellows with a controller supplied with air from an upstream side of the orifice member in the main conduit. The controller regulates pressure in the large bellows as determined by a pressure drop signal across the orifice member and a thermostat. The thermostat vents air from the controller to reduce large bellows pressure for damper closing operation and, conversely, the large bellows is pressurized to cause the butterfly damper to move in the opening direction.

Abstract: A process and an arrangement for determining the perfusion factor of a gas in a sample, particularly of oxygen dissolved in blood flowing through biological tissue, includes measuring the amount of gas diffused from the sample by means of a polarographic cell which comprises a reference electrode having a heat conductive surface which is adapted to be placed in heat-transmitting relationship over a portion of the sample, and a sensor electrode in electrolytic contact with the reference electrode so as to generate a signal indicative of the amount of gas being diffused from the sample portion. A heating unit comprising a high frequency generator to establish a high frequency field in the sample is also provided for heating the sample diathermically to a desired temperature. The temperature of the sample is thereupon detected by a temperature sensor attached to the heat conducting surface, which is operative to generate a control signal for the heating unit which is operative to maintain the temperature of the reference electrode at a substantially constant value. The amount of heat furnished by the heating unit to the reference electrode which is equivalent to the flow of blood stream is thereupon measured so that the perfusion factor of the gas is determinable from the aforementioned measured amounts of gas diffused from the sample portion and of heat supplied to the same.

Abstract: This is a process and apparatus for continuously separating a liquid mixture comprising particulate carbon produced by the partial oxidation of a hydrocarbonaceous fuel, water, and liquid organic extractant into two separate immiscible streams i.e. a stream of particulate carbon-liquid organic extractant dispersion and a separate stream of clarified water. The subject apparatus may be referred to as a carbon decanter and comprises a closed pressure vessel whose horizontal cross-section is circular. Thus, the decanter may be shaped like a vertical cylinder or may be spherical shaped with discharge ports in the top and bottom. The liquid mixture of particulate carbon, water, and liquid organic extractant is charged into said vessel by way of a conduit which terminates at a position within the vessel along the vertical axis about 1/4 to 3/4 of the vessel height and below the interface level which is formed in said vessel when the two immiscible liquids separate by gravity with the water forming a pool at the bottom of the vessel. Alternately, the decanter may be charged through two concentric pipes. A horizontal radial nozzle terminates each pipe. By this means the aforesaid mixture of immiscible liquids may be introduced into the decanter by way of an annular passage located between said pipes. Further, simultaneously a separate stream of liquid organic extractant may be passed through the center pipe and discharged adjacent to the interface level. The dispersion of particulate carbon-liquid organic extractant separates from the water and may be removed by way of the top port as a continuous stream. Simultaneously a continuous stream of clarified water may be removed from the bottom port.

Abstract: Tyre is fitted on a wheel by means of two annular flanges spaced out axially. It has a circumferential wall of elastic material for running, a tread surface facing radially outwards and a pair of elastic side walls. These extend radially inwards from the tread wall to the assembly flanges and form a circumferential cavity. From the side walls, holding flanges extending radially inwards and join the axially inner faces of the assembly flanges. Webs able to yield under load extend across the cavity and are spaced uniformly around the circumference. The webs bind the side walls and are themselves an integral part of a circumferential support ring projecting radially inwards from the running wall. When load is applied to the rin as the tyre rolls, the webs pass one behind the other between the rim and the supporting surface working with the side walls to support and absorb the load. A non-inflatable tyre which can be assembled easily and correctly on a wheel rim, and which performs the functions of support and shock absorber is obtd. The tyre does not set up a stationary wave which resists rolling, in front of the zone of contact of the tread.

Abstract: A method of producing large objects from rapidly quenched non-equilibrium powders in which the powder is first slowly precompacted to a predetermined density without causing any substantial temperature rise. The powder is then rapidly compacted by a shock wave having a short rise time. In this way thin surface regions on the particles are rapidly brought to melting to cause interwelding of the particles. These thin surface regions are then rapidly quenched by conduction of heat to the interior of the particles. Because of the very rapid heating and quenching, in the order of a few microseconds, degradation of the material is avoided.

The pouring spout comprises a number of connected triangular wall panels which are delimited by folding lines. On opening the pouring spout is folded out and the packing container is opened in that an outer end of the pouring spout is removed. To prevent the pouring spout from reverting to its folded-in condition after the opening the folding lines which delimit the material panel of the pouring spout from the upper side of the packing container are arranged so that they run at unequal angles. In this manner the breaking open and the forming of the pouring spout are facilitated.

Abstract: The metering system and method provides an electronic power meter for simultaneously producing digital pulse trains proportional to power and to VARS or Q. In the preferred embodiment, the metering system employs delta-minus-sigma modulation of the voltage signal which produces a modulated output signal used for gating the analog current signal, multiplying voltage and current. The product of voltage and current is then supplied to another delta-minus-sigma modulator (90), which serves as a convertor outputting a pulse train. The converter (90) produces separate pulse trains for each polarity of the power being measured. VARS or Q readings are produced by delaying the output of the modulator (30) by a selected amount to produce the necessary voltage lag, after which the delayed modulated signal is supplied to another multiplying gate. A second converter (90) is used to output VARS and Q. A metering method is also disclosed, as well as an offset compensation system (70, C1) for use with metering systems.
