Patent EP-0329173-B1 (EP)
IPC: B30B15/32
Filed: 1989-02-17
Granted: 1992-09-30
Abstract: Apparatus for compacting and advancing a mass of particulate or fibrous material to a discharge end of a conduit combines an auger (13) with a reciprocating annular piston (23). The improvement of the invention is in driving the piston by way of a flywheel (55) equipped crankshaft (54) which also drives a dynamically counter balancing member (65) to reduce vibrations transmitted to the frame of the apparatus. Special hydrostatic guide sleeves (26) are used to guide the reciprocating piston (23) at a high speed. Further improvements include gas and liquid vents (68) and a cooling jacket (72), both associated with the conduit (C) to increase efficiency of the compacting. A density sensor (79) controlled conical choke member (87) at the discharge end (78) assists in maintaining uniform density of the highly compacted plug of the material. Also, it breaks up the exiting plug to improve subsequent processing of the material. The uniformity of the compacting is assisted by a modified shape of the leading face of the piston which is flat at the outer periphery and frusto conical near the minor diameter of the piston (23). The conduit (C) preferably tapers at about 7 min  to 21 min  toward its discharge end (78).

Title: Apparatus for taking discontinuous measurements on molten metal
IPC: C21C5/46
Filed: 1989-10-05
Granted: 1993-01-07
Abstract: In metallurgical vessels, the production sequence, and especially the refining steps in crucible installations, is monitored by temperature measurement and sampling. This is done using a measuring lance (30) which carries a measuring cartridge (53) and is introduced into the melt through a passage orifice in the metallurgical vessel. In order to be able to introduce the measuring cartridge (53) without damage into the metallurgical vessel, when the passage orifice (6) is blocked by slag, it is proposed to guide the measuring lance (30) for axial displacement on the lance carriage (14) in a sheathing tube (18) and to provide the sheathing tube (18) with a cleaning tool (19) at the end which can be introduced into the metallurgical vessel. <IMAGE>

Granted: 1993-08-18
Abstract: The invention relates to a process for purification and valorisation of effluents, especially from the agri-foodstuffs or agricultural industries, using a coculture of selected yeasts, which process consists in employing under aerobic conditions two strains capable of establishing themselves in a dominant manner in a medium comprising at least the effluent in question constituting the substrate, namely a first yeast strain belonging, for example, to the species Candida kefyr, preferentially metabolising the fermentable sugar, and a second strain belonging, for example, to the species Candida valida, preferentially metabolising the by-products of residual fermentation of the first strain. This process finds its main application in the agri-foodstuffs industry, in particular in the treatment of crude whey, dairy permeates, or alternatively effluents from confectionery or vinegar manufacture or from sugar refineries.

Abstract: Le circuit de protection contre les décharges électrostatiques comprend un canal à dopage P- (11) et un canal à dopage N- (13) qui forment un chemin sériel entre un plot à signaux (20) et un transistor (21). Le canal à dopage P- subit un appauvrissement en trous suite à une décharge électrostatique positive sur le plot à signaux d'entrée (20) et le canal à dopage N- est appauvri en électrons suite à une décharge électrostatique négative sur le plot à signaux d'entrée (20), et le chemin entre le plot à signaux (20) et le transistor (21) est mis en circuit ouvert, le transistor (21) étant ainsi protégé. Inversement, lorsqu'aucune charge électrostatique n'existe sur le plot à signaux (20), le chemin traversant le canal à dopage P- (11) et le canal à dopage N- (13) est hautement conducteur, et donc des signaux passent entre le plot (20) et le transistor (21) très rapidement.

Title: Sewage regulator
IPC: F16K31/30
Filed: 1990-05-03
Granted: 1993-09-08
Abstract: The invention proposes a sewage regulator for outlets from liquid containers, in particular storm-water retention spaces, having a screen (3) which is guided so as to be vertically movable above the outlet opening (2) and is motionally connected to a float (14) via transmission elements (5, 8, 11, 13). The transmission elements comprise a two-arm lever (8) pivotably mounted about a fixed pin (7) and of variable lever-arm length, a first lever arm (8a) receiving a supporting rod (5) connected to the screen or the screen directly and a second lever arm (8b) possessing a guide element (10), and also a control element (11) with a control curve (11a), the control element being pivotably mounted about a fixed pin and being connected, so as to be fixed in terms of rotation, to a float rod (13) receiving the float (14). The guide element of the second lever arm is guided in the control curve of the control element in a tension- and pressure-transmitting manner. The sewage regulator according to the invention makes it possible, independently of the flow characteristic preset by the control curve, to influence the flow rate owing to the variable lever-arm lengths, and it is simultaneously ensured that the screen is driven in a defined manner via the control element in all operating positions. <IMAGE>

Abstract: 2.1 To create trick effects in video recordings, frame buffers or external computers are frequently used. However, these approaches are too complex for consumer electronics. It is therefore the object of the invention to specify a simple arrangement for generating a trick effect. 2.2 This object is achieved by the fact that the digitized image signal is delayed at the time when the colour synchronisation signal occurs. This changes the phase of the colour synchronisation signal by a defined value which results in defined colour changes in the image signal. 2.3 Video devices with digital image signal processing. <IMAGE>

Filed: 1990-10-31
Granted: 1993-07-28
Abstract: To make a locking device for a leaf of a window, door or the like secure against break-ins, the bolt (4), pivotable, for example on the casement, in a plane parallel to the plane of the latter and interacting with a bolt slot formed in this case on the fixed frame, is connected to the push member (2) not directly, but indirectly. The force of the push member is transmitted directly to a so-called bolt guide (6), on which a blocking piece (7) is mounted pivotably and, within a dead-travel stage (10, 11), also displaceably. This blocking piece (7) is coupled to the bolt (4) via a pivot axle (9). Located on the blocking piece (7) is a blocking tooth (19) which interacts with a blocking toothing (20) on the inside of the face plate (1). This consists of saw teeth which cause a blocking of the movement when action is taken from outside on the bolt (4), located in its locking position, with the effect of a reverse pivoting movement (5). <IMAGE>

Abstract: Resonant tubes of a pulse combustor are immersed in a bed of solid particles in a reaction zone to provide indirect heat from the pulsating combustion gases to the solid particles of the bed. The bed is maintained in an agitated state by a gas or vapor flowing through the bed. Reactant materials are introduced into the agitated bed and undergo reaction at enhanced rates resulting from heat transfer coefficients at least about twice as high as those of steady flow combustors and an intense acoustic pressure level propagated from the pulsating combustor into the reaction zone. The apparatus is useful, for example, to steam reform heavy hydrocarbons and to gasify carbonaceous material, including biomass and black liquor to produce combustible gas at relatively low temperatures, with steam being utilized as the bed fluidizing medium. Black liquor gasification, utilizing sodium carbonate as bed solids, results in liquor energy and chemical content recovery without smelt production. <IMAGE>
