Title: Apparatus for heating the air in residential and working environments
Inventor: CIOCCI LUIGI
IPC: F24H3/06
Filed: 1979-02-23
Abstract: For heating the air in residential and working environments, using solid, liquid or gaseous fuel, the combustion chamber (2) of the heating apparatus is surrounded by three walls (5, 6, 7) which enclose ducts (8') which rise and are labyrinth-shaped for conveying air. The zig-zag or broken course of these ducts (8') creates a continuous deviation of the travel of the flow of air, with consequent deceleration and acceleration of the same flow, making possible the maximum absorption of heat. The mass of hot air emerging from these ducts (8') is then collected and subsequently reheated in a flame-trap duct (10) which delimits the combustion chamber at the top. The apparatus is equipped with potentiometer (13) and thermostat (14), respectively for regulation of the number of revolutions of the electric fan (9) and control of its insertion. Thus, the apparatus can supply air only when the temperature in the combustion chamber has reached the predetermined level. <IMAGE>

Title: Silo for storing and delivering hygroscopic or heat-sensitive bulk material
Inventor: KIERSZTAN FRED
IPC: B65D90/14
Filed: 1982-03-26
Abstract: Hygroscopic or heat-sensitive bulk material, such as de-icing salt, especially calcium chloride salt or calcium ammonium nitrate, is stored in a round container made of wood which has a casing (12) which is open at the top and a steep discharging hopper (14). The casing (12) and at least the upper part of the discharging hopper (14) is lined with a water-impermeable film (34) which is folded over the upper edge of the casing (12) and held tight by a profile strip (36) which is placed over the casing (12) and is made of an elastomer. The profile strip (36) simultaneously seals the casing (12) off from a roof (44) which is supported on the upper edge of the casing (12). The lower edge of the film (34) is fastened to the discharging hopper (14) by means of a strip (46) which runs round the inside of the discharging hopper (14). At a short distance over the circumferential strip (46), condensation water channels (50) lead to the outside. As a result of this, the ability of the bulk material to slip downwards in the container and in the discharging hopper of the latter is considerably improved, as the edge layer of the bulk material is unable to absorb moisture from outside through the film. <IMAGE>

Patent CH-650164-A5 (CH)
Title: Method for eliminating local gas concentrations in stratified atmospheres
Inventor: JAHN HERMANN LEOPOLD DR
IPC: B01F23/10
Filed: 1979-08-21
Abstract: The method is used to eliminate local gas concentrations in stratified atmospheres in largely or entirely enclosed spaces such as safety vessels of reactors. According to the invention, this method is characterised in that a perturbation of the equilibrium in the stratified atmospheres is achieved by effecting a local density change in a zone of one atmospheric layer, as a result of which, owing to the density change, this atmospheric layer is locally subject to a vertically directed acceleration which produces convection. The local density change can be effected by introducing a gas into the zone and/or by changing the temperature of the atmosphere in the zone. The method according to the invention is particularly suitable for eliminating hydrogen concentrations in safety vessels of nuclear reactors.
Patent CH-656009-A5 (CH)
Inventor: GOEDE SIMON
IPC: G01S17/50
Filed: 1981-12-17
Abstract: The invention relates to a method and apparatus for measuring the velocity of a moving object. Measuring beams composed of sequences of optical pulses are directed towards the object which is to be measured and follow such object. Based upon transit time measurements of reflected pulses there are formed distance values and distance difference values. While taking into account the time interval of the pulse sequence there are computed velocity measuring values and velocity values computed from homogeneous groups of values are displayed as reliable velocity values. By means of a measuring beam deflection system there are directed measuring beams into defined solid angle sectors towards the object which is to be measured, and reliable velocity measuring values computed from homogeneous groups of measuring values from the measuring channels correlated to the individual solid angle sectors are displayed as binding or valid velocity measuring values if there is present a confirmation of the value from further solid angle sectors.

Title: Process and device for cleaning a gas
Inventor: SCHNEIDER JUERG
IPC: B01D47/06
Filed: 1976-06-30
Abstract: A scrubbing liquid is sprayed into the gas to be cleaned and the gas is then forced or sucked through a separating wall (4) with passage slits (16a, 16b). Within the wall (4) the gas stream is split into partial streams which in turn are greatly accelerated and then allowed to impinge on one another at an angle in pairs. Because of the impinging against one another, the partial streams are sharply deflected and subsequently they are slowed down again. The acceleration of the partial streams takes place in that the passage slits (16a, 16b) are designed so as to taper from the outside inwards. In each case two pairs of V-shaped converging and diverging slits (16a, 16b) are arranged opening into one another in an X-shaped manner, the narrowest points of the slits (16a, 16b) being located in their common opening region. The separating wall (4) is built up from individual profile bars (9, 10, 11) which are held at a mutual distance and form the passage slits (16a, 16b) between them. The wall (4) preferably consists of at least two wall parts (4a, 4b) which are connected to one another in a hinge-like manner. <IMAGE>
