Title: Creation of micro-bubbles from the flotation sepn. of a suspension - with gas saturation chamber, cavitation zone and flotation chamber in which supersaturation occurs
IPC: B03D1/24
Filed: 1978-07-19
Abstract: Particles or droplets of an immiscible fluid suspended in a liq. are removed by a flotation process in which microbubbles formed in the liq. adhere to the suspended particles and float them to the surface of a flotation chamber. The micro-bubbles are created by saturating the suspension with a gas and then passing it through a channel contg. a flap valve leading to the flotation chambers. The flap valve is periodically and suddenly closed and opened causing low pressure waves to be created and consequent cavitation in the flowing fluid. The micro-bubbles are formed when the cavities implode further down the channel. The flow is so arranged, that the micro-bubbles are formed in a zone in which the fluid is super-saturated with gas so that, as the bubbles collect particles, they also grow.

Title: Integrated cct. incorporating printed wiring - has multilayer current injection forming rectifier bridge with interzonal diode junctions
IPC: H01L27/02
Filed: 1982-12-17
Abstract: The integrated circuit has several transistors arranged near one another on a surface (11) of a semiconductor body (12) and there is an intermediate layer (21) of the first conducting type forming a common zone for several transistors and for each of these there is a second zone (1 to 10), an adjusting zone of the second type bordering the first layer as a rectifying junction (19). These second zones each have a terminal for electrical signals (14), forming part of a pattern of conducting paths, and each acts as the last layer of a three-layered structure (20,21,6) for a current injector or current adjusting source. The structure includes an injecting layer (20) and the intermediate layer (21), separated from the injecting layer by a first rectifying junction (18) and from the last layer by the second rectifying junction (19). The first junction is polarised, to supply the charge carriers to the last layer, in the direction of transmission.

Abstract: A valve for regulating a fluid flow through a pipe conduit, comprising a housing, a generally annular valve seat mounted fixedly in the housing and a valve element which interacts with the said valve seat and can be moved towards and away from the valve seat, one of these interacting components being provided with an O ring of a resilient material accommodated in a groove and the other component having an encircling, relatively sharp sealing edge so that, in the closed position of the valve element, the contact between the sealing edge and O ring takes place essentially along a circular line, and the O ring being accommodated in a groove of a design such that, when considered in every axial cross-section, only a part of the surface of the O ring over an arc of 20@-75@ is exposed to the outside for interaction with the sealing edge, the surface into which one of the sides of the opening of the groove merges being configured in such a way that, in each opened position of the valve element, the narrowest passage for the fluid between the valve element and the seat is always bounded by the sealing edge on one side and this narrowest passage lies downstream of the circular line on the O ring.
Patent NL-8600617-A (NL)
IPC: B21D26/02
Filed: 1986-03-10
Abstract: A method of forming a ridge in a cylindrical tube member comprises placing the ends of the tube member into spaced-apart dies so that each die is a close fit around the respective end of the tube member, and the tube member has a free portion between the ends. Liquid is supplied to the interior of the tube member and the liquid pressure within the tube is increased so that its free portion bulges radially outwardly. While the radial bulge of the free portion of the tube member is continuously measured on the outside, the liquid pressure is gradually increased depending on the radial bulge measured until a pre-determined radial bulge is measured. Thereafter, while the liquid pressure is maintained in the tube member, the dies are axially moved towards each other until they are spaced a pre-determined axial distance apart. During this displacement the dies deform the bulge until the desired ridge form is reached. Thereafter, the liquid pressure within the tube member is released, the dies are axially moved apart, and the tube member is removed.

Patent NL-9302124-A (NL)
Title: Method for processing waste and/or compost
IPC: C05F9/00
Filed: 1993-12-07
Abstract: This method firstly involves removing coarse material from the initial waste mixture. Then, the waste mixture obtained is mixed with water, and preliminary separation of heavy inert constituents from the mixture takes place. Next, the mixture is separated into a coarse organic fraction and a finer fraction, and inert material is taken out of the finer fraction. Finally, the finer organic fraction is subjected to a final treatment, ultimately producing a sludge cake and a fine organic fraction. The latter fraction can be added to the coarse organic fraction. The sludge cake may contain undesired contaminants and can be landfilled.

Date Mar. 7, 1991.In manufacture of a glass architectural panel (FIG. 1) an aluminium foil is bonded to a glass sheet via a layer of thermosetting polyester powder-coating material. The powder is deposited on the foil as the foil unrolls and is melted to provide a fused layer which is then cooled to solidify the layer and arrest progress of curing. The solidified layer is sprayed with a silane adhesion promoter, before being heated momentarily to enable the foil with its adhering and solidified, but uncured, layer, to be rolled up for storage. The rolled foil is transferred nearer to a float-glass production line, where, after being heated to allow it to be unrolled, it is fed onto a hot glass sheet emerging from the line. The fused layer melts as it is brought down with the backing foil to contact the glass sheet and fulfil the cure of the powder material so as to establish the bond. Instead of a single foil, several may be provided overlapping one another (FIG. 3). Decorative effects can be obtained using different pigmentations of powder and partial metallization of the glass (FIG. 4). The technique of interrupting the cure is applicable to provision of a glass window (FIG. 5) and a glass laminate (FIG. 6).

Date Oct. 31, 1991A measuring method for vehicles equipped with an internal combustion engine, the engine including a starter battery and a driven staffer motor used when an attempt is made to start the engine, is disclosed. According to the method, a voltage across a measuring shunt inserted in a current circuit between the battery and the starter motor is repeatedly measured, at a sampling rate, during each revolution of a crankshaft of the engine during activation of the starter motor. Corresponding values of a current delivered from the starter battery to the starter motor are derived from voltage measuring results. Values of the current are registered in a memory of a measuring computer. The registered values are used to establish a status of the combustion engine and its starting system. A value of a derivative of a rotational speed of the combustion engine crankshaft is obtained from the registered values. The sampling rate is sufficiently high to permit obtaining the value of the derivative of the rotational speed of the combustion engine crankshaft.
