Abstract: The invention concerns a ventilation means (10) comprising at least one fresh air intake duct (11, 110), and said ventilation means (10) comprising a means producing air flow circulation, fresh air being introduced through the intake duct into a room space. The ventilation means comprises a blower means (22, 220a) and/or (220b) or equivalent producing air circulation and disposed in the space defined within themselves by a first heat transfer and/or filtering circle (19, 190) and a second heat transfer and/or filtering circle (19, 190) and a second heat transfer and/or filtering circle (20, 200). The blower (22, 220a and/or 220b) or equivalent is disposed to move and transport part of the air from the area (A2 and/or A2', or A20' and/or A20'') on the intake side of the blower (22, 220a and/or 220b) to the area (A1; A10' and/or A10'') on its delivery side and thence through the ribbed surfaces of the heat transfer circle on the delivery side of the blower (22, 220a and/or 220b) to an area (A3) in the ventilation means (10) and further into the room space, and from the area (A1; A10' and/or A10'') by an induction duct (30a and/or 30b; 300a and/or 300b) to a point adjacent to, and advantageously above, the fresh air duct (11 and/or 12; 110 and/or 120), whereby the air flow coming through said induction duct that has been produced by the blower induces and attracts fresh outdoor air coming through the fresh air duct (11 and/or 12; 110 and/or 120). The invention also concerns a ventilation procedure.

Abstract: The invention relates to screens for limiting heat losses from heated material, e.g. bars and slabs in rolling mills. Screens (20) are provided in the form of strings of heat insulating bodies composed of metal shells (32) containing insulating material (40). These screens may form curtains and/or covers (24) for the hot material. Containing chambers for the hot material may be provided with such strings of elements and the chambers may also comprise means for limiting heat conduction losses through the material supports therein. The screens may be collapsed over the hot material thereby completely surrounding and insulating the material from loss of heat. A displaceable chamber installation is also described for limiting heat loss when holding and transferring hot material between processing stages.

Abstract: Lofted non-woven materials are formed by bonding fibres and used for, e.g. furniture filing and heat insulation. The flammability of these materials is an important characteristic. The use of copolymer emulsions having defined Tg, molecular weight and solution viscosity as binders allows the material to melt away from an open flame. Thus the flammability of the non-woven material is reduced.

Abstract: The clipping circuit has a voltage reference (3) and a transconductance (5) connected to a voltage input (Vin). The input is connected through the transconductance (5) to an output resistor (Rout). The voltage output is taken between the output resistor and the transconductance (5). The voltage reference (3) has a third current source (I3) feeding a diode connected transistor (Q1) and a resistor (R1). A second current source (I2) feeds into the resistor after the transistor. The base of the diode connected transistor (Q1) is connected to the voltage input. The transconductance (5) has a second transistor (Q2) whose base is connected to the voltage input, collector sinks current from a fourth current source and emitter feeds current to a resistor (R2). A first current source (I1) feeds. current to a third transistor (Q3) and to a current mirror. The base of the third transistor (Q3) is connected between the fourth current source (I4) and the collector of the second transistor (Q2). The current mirror draws current from the output resistor (Rout) and feeds current to between the emitter of the second transistor (Q2) and its associated resistor (R2). The transconductance creates a feed back loop such that a change in the first and second current sources creates a steady-state current drawn through the resistor (R2) that is one-half of the first current source current. The circuit produces symmetrical clipping of an input voltage signal at the voltage output.

Abstract: An electrical rear view vehicle mirror is attached with a mirror carrier (18) to a spherical shell (12) of a shell bearing which has bearing elements (6-16) which have permanent magnets (14, 16) and are attached to a housing (2). As a result, the spherical shell can be held in the bearing elements with a defined degree of holding and sliding friction. Adjustment of the mirror carrier (18) about a centre of rotation (M) is made with the aid of coupling pins (22) on the piston (24), which pins engage on the mirror carrier (18), and by means of two linear motors (20) which are fed with current pulses which are sufficient in each case for the force of the linear motors to overcome the holding friction force of the shell bearing in order to adjust the mirror carrier by a small amount at each pulse. <IMAGE>

Abstract: Caustic dezincing galvanized steel scrap. A dezincing plant includes a plurality of tanks (14, 16, 18) interconnected in series with steel scrap sequentially being moved through each of the tanks. The tanks (14, 16, 18) contain a caustic leaching solution including an oxidant with the leaching solution being circulated through each of the tanks (14, 16, 18) in a direction opposite to the movement of the scrap. Fresh scrap initially is exposed to a partially depleted leaching solution with the oxidant concentration of the leaching solution increasing as the scrap moves through the series of tanks (14, 16, 18). Leaching solution depleted of its oxidant is transferred to an electrolytic cell (22) where zinc is removed and plated as metallic zinc powder onto a cathode. The leaching solution is recycled by removing zinc. The chemistry of the leaching solution is controlled so that sufficient free caustic is present to prevent passivating zinc coating on the scrap. Oxidant is added to the recycled solution and the caustic concentration is adjusted, if necessary, to have a total caustic concentration of at least 5 M and the recycled solution is returned to the last tank (18). Compressed scrap bales are dezinced and ready for use as a melting furnace charge material. <IMAGE>

Abstract: A digital virtual earth active cancellation system which receives a phenomena input signal representing residual phenomena to be cancelled and has an adaptive filter which generates a cancellation signal. A system impulse response is convolved with the cancellation signal and is subtracted from the input signal to produce an estimate of noise. This substantially eliminates the problems associated with destructive feedback due to phase shifts. The residual signal is used to control an adaptive filter that receives the estimated noise as an input. The adaptive filter produces the cancellation signal by filtering the estimated noise with filter weights that are adapted using the residual signal and the estimated noise convolved with the system impulse response.
