Title: Face visor for low temperature environments
IPC: A62B17/04
Filed: 1979-10-24
Abstract: A face mask, to be worn by a wearer in dry cold weather, in which mask condensation and fogging are prevented, has a transparent visor overlying the eye and nasal areas of the wearer, and support means including a support harness. To inhibit condensation of moisture on the internal surface of the visor, a nasal cup is provided, being spaced from said visor and supported in a manner so as to form with the visor an air conducting channel. The nasal cup encloses a space in the nasal area. An inhalation valve in said nasal cup permits unidirectional air flow through the same upon inhalation by the wearer. Inhalation creates a pumping action to momentarily evacuate the enclosed space, such evacuation inducing a flow of dry cold air through the conducting channel and inhalation valve means. This flow of dry cold air inhibits the condensation of moisture on surfaces of the visor internally of the face mask. A supporting base member may also be provided, connected to both the visor and nasal cup so as to support the nasal cup. In a preferred configuration, the visor, supporting base member and nasal cup are integrally connected, being formed as a moulded, unitary structure. An exhalation valve means may also be provided, being operative upon exhalation by the wearer to permit the unidirectional flow of warm moist air from the enclosed space to the ambient environment. <IMAGE>

Title: Process for milling grist and other materials to be milled
IPC: B02C1/08
Filed: 1979-03-27
Abstract: In the milling of wheat and other delicate materials to be milled, an improvement of the quality of the finished product is achieved by increasing and decreasing rapidly and alternately the milling space formed between at least two rollers of a roller type mill, said space being adjusted to a minimum value, by means of periodic oscillations of one of the rollers with respect to the other. A highly pronounced differentiation can be achieved, in other words an improvement of the quality of the finished product, if at least one grinding body (3), forming with another grinding body (2) a grinding space, has a convex or cylindrical cross-sectional profile, whereas the other grinding body (2) has, preferably, a concave section and does not rotate about its proper axis. The surface of the concave grinding body, of which the radius of curvature is generally bigger than the sum of the radius of curvature of the co-operating grinding body plus the minimum grinding space, can be structured in a different way by sections in the feed direction of the material to be ground. Adjustments (101) of one of the grinding bodies (2) with respect to the other (3) allow to adapt the grinding, to a large extent, to the material to be ground. <IMAGE>

Title: Corrosion monitoring system
IPC: G01N17/00
Filed: 1979-11-24
Abstract: The invention relates to a method and apparatus for monitoring the corrosion of a vessel or pipe which is exposed to a corrosive medium. A current is passed through two series resistive elements (14, 16) one of which (14) is a sample element exposed to the corrosive medium and the other of which (16) is a reference element. The two voltages generated across the respective elements are sampled and then integrated and subtracted from one another by an integrator (20). The reference element voltage is periodically sampled at a fixed sample rate and pulse width while the sample element voltage is sampled at a fixed pulse width but at a rate which varies in a manner such that the result of the subtraction of the two integrated voltages tends to zero. The frequencies of the two sampling rates are then compared to provide an indication of the degree of corrosion. The sampling frequency of the sample element voltage decreases relative to the sampling frequency of the reference element voltage as the resistance of the sample element increases with corrosion. <IMAGE>
