Title: Differential gear
IPC: F16H48/08
Filed: 1976-08-17
Abstract: An annular intermediate part (4) and side parts (2, 3) fixed to it form the housing (1) of the differential. The housing is pivotably mounted on hollow journals (2a, 3a) and driven by a pinion meshing with an annular gear (22) fixed on the intermediate part (4). Differential bevel gears (17) rotate about journals (16) fixed in a sleeve (15) and mesh with bevel gears (10, 12) rotating with axle shafts (8, 11). Thrust bearings (18) for the differential gears (17) are guided in slots (4a) parallel to the axle (20) so that they are displaceable but cannot rotate. In this way, increased wear caused by positional changes of the axle shaft bevel gears due to abrasion processes or manufacturing inaccuracies can be reduced. When designed as limited-slip differential the bevel gear (10) can be connected by way of toothing (7a, 10a) disengaging the gear (10) and a coupling gear (7) at high torques. In light trucks, friction rings (23-26) are sufficient, of which some (24, 25) are rotationally fixed to the intermediate part (4) and the others (23, 26) to the assigned gear (7 and 12). In passenger vehicles the friction rings (23-26) can be replaced by thrust bearings.

Title: Method and arrangement for determining alcohol content in the breath
IPC: G01N21/35
Filed: 1976-10-14
Abstract: A method for determining the alcohol content in the exhaling respiratory air using an alcohol measuring instrument and measuring the alcohol content when the exhaling air transmits the determined value of the alcohol concentration. This determined value of alcohol concentration occurs when the time variation related to the height of the alcohol signal is below a predetermined threshold value and the velocity of flow of the exhaling air is above a given value and is maintained without interruption for a given time. The apparatus includes an infrared measuring instrument which is connected into the respiratory air current and measures the alcohol concentration of the exhaling air. This value is applied to an indicator through a linear gate when an AND-gate is triggered by threshold comparators and a timing element activated by a threshold comparator.

Patent ES-465234-A1 (ES)
Title: Process and plant for the continuous unloading of the heavy-duty containers in a pneumatic transport system
IPC: B65G51/06
Filed: 1977-12-20
Abstract: A system for the continuous unloading of the containers of pneumatic transport vehicles to which an initial velocity is imparted by pneumatic displacement within a transport tube section, while the movement of the vehicles beyond the transport tube section is caused by inertia, the vehicle being suspended from an overhead rail. The unloading of the vehicle container is performed by operating a latch which engages an uncoupling cam provided on the rail, thus causing the release of the container at its rear end and the pivoting of the container around its axis in the vertical plane while the container remains suspended at its front end. The emptied container is brought back to the initial position by allowing the vehicle to descend along a downward slope of the overhead rail by gravity, while the lower part of the container is lifted by riding on an upwardly inclined plane, so that the latches on the vehicle are coupled with pins provided at the tip of the container in order to hold the container in the initial load-carrying position.
Patent ES-465983-A1 (ES)
Title: Device for use in connection with heat exchangers for the transfer of sensible and/or latent heat
IPC: F24F7/08
Filed: 1978-01-13
Abstract: A device for use with heat exchangers for the transfer of sensible and latent heat between a gaseous and liquid medium is provided. The device includes a first set of narrower passageways defined between at least two corrugated foils to receive the liquid medium, and a second set of wider passageways to receive the gaseous medium. The surfaces of the foils defining the narrow liquid passageways have closely spaced fine ridges which cross the corrugations. These fine ridges cause flow resistance and result in the liquid medium in the liquid passageways being distributed over the entire surface area of the foils defining the liquid passageways, thus enhancing heat transfer. Furthermore, because the ridges tend to rigidify the foils defining the liquid passageways, these foils can be formed from a relatively thin material, thus further enhancing heat transfer between the liquid and the gas mediums.

Title: Purification of exhaust gases from industrial furnaces and sludge separator for use therein
IPC: B01D53/81
Filed: 1978-11-16
Abstract: A process for purifying the exhaust gases from industrial furnaces and especially from waste incineration plants is described in which process the exhaust gases which contain acid, neutral and/or basic pollutants in the gaseous or solid form or in the form of a mist, are treated in an evaporative cooler 1 and then in a dry purifier 2, in which they are freed from at least a substantial portion of the solid pollutants, are finally in a scrubber 3 by means of a wash liquid. The temperature of the exhaust gases in the evaporative cooler is kept above the dew point, and the wash liquid in the scrubber is cycled through a sludge separator 4, from which the suspension or solution of pollutants is withdrawn and fed into the evaporative cooler and mixed in a mixing space in the latter with the hot exhaust gases. Those walls of the evaporative cooler which come into contact with the mixture of exhaust gases and recycled suspension or solution of pollutants and which consist of a material that can be corroded by the said mixture at room temperature are heated to a temperature above the dew point. There is also described a sludge separator for use in such a process.
