Title: Vacuum evaporation and deposition
Inventor: LOVIS GORDON DAVID
IPC: C23C14/30
Filed: 1988-08-26
Abstract: A method of evaporating a source material, and a vapor source assembly (2) for carrying out said method, comprising heating and evaporating said source material (48) and providing a hearth (21) having a downwardly tapering supporting surface (61), preferably concave and substantially conical, with the source material spaced apart from the bottom of the hearth. The method and source assembly are suitable for the processing of materials which melt and form a preferably substantially spherical molten droplet, and also for materials which sublime and are provided in a substantially spherical form. Prior need for sweeping a charged particle flux across source material is avoided, focusing is less critical than for prior sources, and contamination of source materials is reduced.

The first filter, having a first input terminal (103, 153) and a first output terminal (105, 155), is coupled to a first input signal including the first frequency signal at the first input terminal and attenuates first frequency compornent of the first input signal below the first frequency range at a first attenuation rate and second frequency compornents of the first input signal above the first frequency range at a second attenuation rate. One of the first input and output terminals of the first filter is coupled to the antenna terminal. The first filter further has a first setting terminal setting the first attenuation rate and second attenuation rate so that the second attenuation rate is greater than the first attenuation rate. While the second filter, having second input (109, 159) and output terminals (111, 161), is coupled to a second input signal including the second frequency signal at the second input terminal and attenuates third frequency compornents of the second input signal below the second frequency range at a third attenuation rate and fourth frequency compornents of the second input signal above the second frequency range at a fourth attenuation rate. One of the second input and output terminals of the second filter is coupled to the antenna terminal. The second filter further has a second setting terminal setting the third attenuation rate and fourth attenuation rate so that the third attenuation rate is greater than the fourth attenuation rate.

IPC: B09B3/00

Abstract: A method is described for utilizing metal containing by-products or waste products of metallurgical processes. The metal containing particles, or dust originating in metallurgical processes are agglomerated with a combustible agglomerating agent, and are usually charged to smelters, converters, or similar high temperature installations for the recovery valuable metals present in such dust particles. The agglomerates are obtained by mixing the dust particles with an amount of combustible agglomerating agent. The amount of agglomerating agent used for producing the agglomerates is related to the bulk specific gravity and the particle size range of the dust particles. The combustible agglomerating agent of this method, such as hydrocarbon wax, tar, bitumen, distillation, residue and similar combustible material, is solid at ambient temperatures. 
     In the preferred embodiement the combustible agglomerating agent is mixed with the dust particles at a temperature above the melting point of the agglomerating agent, the hot mixture is subsequently allowed to cool in a   mould and compacted. The cooled compacts are removed from the mould before utilization. In a particular form of application of this invention the mixture is allowed to cool in combustible containers and may subsequently be utilized as compacts bonded to their containers. 
     The agglomerated particles may be used for non-combusted purposes as well, such as support structures or filling in cavities, or merely for protecting the environment from loose dust particles of metallurgical origin.

Abstract: A powered respirator comprises a motor-driven fan unit (11) drawing air through an upstream filter (16) for delivery to a facepiece (1). Operation of the fan motor (13) is controlled in response to a differential pressure sensor (17) tapped in across the fan unit (11) so as to reduce the fan throughput in response to an increase in the pressure differential and to increase the fan throughput in response to a decrease in the pressure differential, and thereby match the delivery of air to the breathing demand of the wearer. The diaphragm (20) or other pressure-­responsive member of the sensor (17) is isolated from unfiltered air and can therefore provide no leakage path for contaminants to the facepiece (1). In an alternative embodiment (Fig. 4, not shown) the positions of the fan (12) and filter (16) are reversed so that the fan (12) is upstream of the filter (16), and similarly controlled in response to the differential pressure across the fan (12). In the latter arrangement any contaminant which could pass through the pressure sensor is removed by the downstream filter (16) before delivery to the facepiece (1).
