Patent EP-0050288-B1 (EP)
IPC: A01F25/13
Filed: 1981-10-12
Granted: 1985-01-16
Abstract: The water content of a material, which tends to either absorb water or to release water, is changed with the aid of a film, which at least partially separates the material from the adjacent space and is impermeable to liquid water but permeable to gaseous water. Polyvinyl alcohol with a particular degree of polymerization and degree of hydrolysis is used as the film material. The film can be mechanically or chemically after-treated. The moistening or de-moistening of the material, which is solid, liquid or gaseous, is effected, utilizing a water vapor pressure gradient, under very mild conditions.

Abstract: A rotary fluid seal, especially an oil seal for a rotary shaft, comprises a sealing ring between axially-opposed divergent frusto-conical counterfaces of relatively rotatable members, preferably casing rings in a self-contained seal unit, the sealing ring having a pair of divergent sealing lips presenting frusto-conical contact faces to the counterfaces and being substantially coaxial with but floating freely between the relatively rotatable members, the contact faces bearing frictionally on the counterfaces so that, on relative rotation of the members, the sealing ring is frictionally driven into rotation by one or other of the members and the effect of centrifugal force, tending to cause the sealing lips to flex angularly outwardly, reduces the bearing load of the contact faces on the counterfaces.

Title: Emergency transmitter and operating method thereof
IPC: H04B1/034
Filed: 1983-01-19
Granted: 1986-03-05
Abstract: The transmitter is provided with separate means for the transmission of a first frequency and a second frequency. It is contained within a floatable housing. The transmitter is connected through a switch to a battery. The transmission means are comprised of a common quartz oscillator connected with frequency multipliers which are connected to drive stages and to high frequency final stages. The latter are connected to a transmission antenna which extends from the housing, as well as to a signal generator for modulating the transmitted frequencies. A problem raises when rescuing at sea as to the size and weight of the apparatus in particular when it is permanently carried by a person. A decrease of these parameters is not possible beyond a certain limit due to the capacity of the battery and the transmission output. To solve that problem without decreasing the range and duration of transmission while reducing almost by half the size of the battery as well as the power that it should deliver, a clocked control device (for example 36) is incorporated to the first (11) and to the second (13) transmission means which alternately sets in operation both means (11, 13). Thus, the operation requirements of the battery are reduced to those necessary for a single transmission device.

Granted: 1988-06-29
Abstract: An industrial furnace for heat-treating metallic workpieces has separate heating and cooling chambers. The latter uses a circulating cooling gas, the flow of which against or past the workpieces produces cooling or gas-quenching. The furnace may have another chamber for oil-quenching lying below the gas-cooling chamber. In order to enable the gas cooling to operate quickly and efficiently, a cooling box fed with air by ventilator fans is provided in the shape of a tunnel, with internal surfaces above and at both sides of the effective cooling space constituted by interchangeable nozzle plates (or blank plates if no nozzle openings are desired at the top or at the sides). The workpieces to be cooled rest on a platform which may be raised or lowered to adjust the distance from the top nozzle plate or lowered into an oil bath. The nozzle plates provide a choice of nozzle patterns for different articles or groups of articles to be cooled after heat treatment. The nozzle plates may have setbacks or protrusions in order to vary the spacing of the nozzle openings from the median plane of the cooling tunnel.
