Abstract: Method and apparatus for forming three dimensional shaped webs. The apparatus controls the flow of entraining air for an air laid web by restricting passage of the air through selected zones of a condensing surface. By limiting the open area in a zone of a suction plate the amount of fibers condensed over the zone is reduced permitting control of location of and amount of deposit. The duct work defining the conduit for the entraining air may also be shaped or provided with blocks to prevent scavenging of fibers which have already been deposited.

Abstract: A device for the recombination of hydrogen and oxygen with the aid of a catalyst arrangement contains the catalyst arrangement in a housing (1), which has at least one inlet orifice and at least one outlet orifice which are closed in a gas-tight manner with first closures (7), which open in a temperature-dependent manner, as long as the temperature does not exceed the response temperature of these closures. In the housing, a gas-permeable filter arrangement is further arranged in such a manner that after the opening of the first closures, gases or gas mixtures entering the inlet orifice reach the catalyst arrangement only after passing through the filter arrangement. The filter arrangement is essentially impermeable to aerosols and fat. The housing (1) has at least one further orifice which is sealed in a gas-tight manner by a second closure (5a, 5b), which opens in a temperature-dependent manner, as long as the temperature does not exceed the response temperature of this second closure, the response temperature of this second closure being higher than that of the first closures, and the second orifice being arranged in the housing in such a manner that the catalyst arrangement, after the second closure has opened, is directly subjected to the atmosphere surrounding the housing without intermediate connection of the filter arrangement. <IMAGE>

Abstract: An enclosed motor-driven compressor includes a vertical crankshaft (25) rotatably supported by two ball bearings (26, 27) and having an eccentric portion (28) through which a motor element (21) and a compressor element (22) are operatively connected. The two ball bearings (26, 27) are disposed on opposite sides of the eccentric portion (28) so that a reaction force of a piston (35) which is exerted on the eccentric portion (28) is supported evenly by the ball bearings (26, 27). With the ball bearings (26, 27) thus arranged, the load on the crankshaft (25) is lowered and the efficiency of the motor element (21) is increased. A lubricating oil (33) held at the bottom of a container (20) is sucked through an internal groove of the crankshaft (25) and then supplied from outlets (37b, 37c) to the respective ball bearings (26, 27). The ball bearings (26, 27) thus lubricated have a prolonged service life. The compressor may have an oil sump disposed either above or below the ball bearing (26) for improving lubricating condition of the ball bearing (26).
