Abstract: An air escape for ventilation systems in vehicles comprises manual adjusting means for as outflow direction and for an outflow volume. The manual adjusting means have a single operating element that is movable in translation and in rotation about an axis, translational movement of the operating element causing a change the outflow direction and rotational movement causing a chang of the volume flow. The operating element is connected by a cardan shaft (24) to an actuating drive that converts rotational movement of the cardan shaft into an adjustment movement of an air flap.

Abstract: A ventilation apparatus for arranging in a wall-surface region of a building. Such ventilation apparatuses are customary for so-called unheated sheds (stables, cowsheds, pigsties, etc.). In this case, an outer side of a shed building is closed against the entry of wind only with one or more tarpaulin-like wall elements, which are arranged one above the other and can be opened for more extensive ventilation of the shed by virtue of the fact that the wall element is wound toward the top like a roller blind. The object of the invention is therefore to provide a ventilation apparatus in which the wall element is opened by defined or controlled lowering of the top margin of the wall element while simultaneously winding the wall element and only by means of a single drive.

Abstract: An apparatus and related method for selectively dispensing oxygen into an enclosed space is provided. The apparatus includes a pressurized container comprising oxygen and an actuator which can be moved between discharging and non-discharging positions, a means for mounting the pressurized container such that upon discharge the container will dispense oxygen into the enclosed space, an electrically-operable actuating means which effects movement of the pressurized container actuator between the discharging and non-discharging positions, and a sensor disposed in the enclosed space and in electrical connection with the actuating means for detecting a preselected property of the atmosphere in the enclosed space, wherein when the sensor detects the certain preselected property, the actuating means moves the aerosol container actuator into the discharging position, thereby providing for oxygen to be discharged into the enclosed space.

Abstract: The invention relates to a method for regulating the atmosphere in a substantially closed sports/exercise space (1) or an animal shelter (11), especially in terms of partial oxygen pressure. In the method, the normal atmosphere of said space (1; 11) is admixed with nitrogen for the creation of a desired low-oxygen (oxygen content <appr. 21%) atmosphere, said low-oxygen atmosphere corresponding to partial oxygen pressure in the air at a certain altitude above sea level. Alternatively, said normal atmosphere is admixed with oxygen for the creation of a desired high-oxygen (oxygen content>appr. 21%) atmosphere. Said mixing of nitrogen or oxygen with air is carried out at normal air pressure.

Abstract: A process and system is provided for treating the air being taken into a building so as to remove moisture, especially snow, from the intake air. The system includes a series of air passages through the building; generating a flow of air through the series of air passages, wherein air is taken from outside the building; and, advantageously, reducing the content of snow in the intake air by passing the intake air through a mesh pad having a heating means disposed at its intake surface.

Abstract: An adjustable roof jack interconnects a roof-mounted air handler with a duct opening through the roof of a building in a full range from flat to a 6-in-12 pitch; so that a single roof jack is capable of use in substantially all standard construction. To accomplish this, the roof jack includes a lower rectangular box-like member, which is attached to the roof. An upper rectangular box-like member is made for attachment to a roof-mounted air handler; and the front and sides of the upper box-like member extend downwardly over the corresponding side and front of the lower roof-mounted member. The upper member is pivotally connected to the lower member at pivot points located through the sides intermediate the front and back of the two members.

Abstract: An apparatus for ventilating the passenger space of a rapidly moving elevator car generates an air flow through the car during the travel of the car in an elevator shaft. A plurality of ventilation slots are provided one above the other and open to the passenger space of the elevator car and to a ventilation channel extending vertically in one wall of the elevator car. The total cross-sectional area of the ventilation slots is approximately twice as great as the cross-sectional area of the ventilation channel. The ventilation slots are formed by carrier slots in a sheet metal carrier on which a plurality of strips of a laminated material plate are attached on a passenger space side thereof and on which a perforated metal reinforcing plate is spot-welded on a rear side thereof. The reinforcing plate has rows of apertures formed in generally V-shaped grooves aligned with the ventilation slots. The grooves space the apertures from the carrier.

Abstract: A construction element for a noise-suppression shed of the type used for ground-testing jet engine aircraft. These sheds usually have transversely extending continuous apertures for the admission of fresh air, the inner face of the shed's roof being provided with spaced liners of a sound-absorbing material defining flowpaths for fresh air entering the interior of the shed. The element comprises a cover panel element carried by a mounting structure and having a stepped profile configuration in the longitudinal direction of the shed, and mutually spaced first and second elements of a sound-absorbing material. The arrangement of a plurality of construction elements in rows extending in the longitudinal and transverse directions and interconnection of the respective mounting structures results in the formation of continuous air inlet gaps extending over the full width of the roof and passing between the sound-absorbing liners.

Abstract: A method for making seamless tilted vent comprises the spinning of a mold and a metal sheet to form a tubular member and a flat angular shackle continuously extending from and around the tubular member. The mold is made of a cylindrical member and a flat collar surrounding the cylindrical member at one end. The collar is agularly disposed relative to the cylindrical member and the metal sheet is tightened in abutting relationship against the other end of the cylindrical member. The spinning takes place about an axis corresponding to the longitudinal axis of the cylindrical member. The chasing operation of the metal against the cylindrical member is made until the metal sheet reaches the intersection of the cylindrical member with the collar to form a tubular member. The speed of the mold and of the tubular member is then set between a maximum speed not exceeding 400 RPM and short intervals of speed substantially reduced from said maximum speed.
