Title: A procedure for measuring the throughput volume or mass or the grain size of divided products, and apparatus for putting this procedure into effect
Inventor: LAVANCHY GERARD
IPC: G01F1/64
Filed: 1983-04-13
Abstract: The present invention relates to a procedure and apparatus for measuring the throughput or the grain size of divided products. The apparatus comprises essentially a hopper (11), a detection electrode (13) held at a potential which is different from that of the hopper, an amplifier (18) and a measuring circuit comprising, for example, three branches (7, 8 and 9). At the time of their passage over the electrode (13) the particles discharged via the hopper (11) are charged. The current coming from the electrode (13) is amplified, and its continuous and pulsating components are measured by measuring instruments (20 and 24), or are used by a counter (26). This apparatus may be used for determining the grain size of a product when its throughput is known, or the throughput of a divided product when its grain size is known. <IMAGE>

Title: Pressure relief plugs
Inventor: ROBINSON GEOFFREY
IPC: A47J27/09
Filed: 1983-06-30
Abstract: A pressure relief plug for a pressure vessel includes a resilient member 5 which can be mounted in an aperture 9 in the vessel cover or top wall. A closure member incorporating a valve portion 18 is movable axially through an aperture 12 in resilient member 5 to close the aperture at a predetermined pressure (Fig. 6). A further rise in pressure will force the valve portion 18 up through the aperture 12 to vent the vessel. The resilient member 5 is forcibly expelled from the cover or top wall if the pressure within the vessel reaches an unacceptable level but the plug is retained attached to the cover or top wall by means of a retaining member 16 within the vessel (Fig. 8). The retaining member 16 has a length greater than a diameter of the aperture 9 in the vessel cover or top wall. The valve portion 18 is of fusible material which melts in the event of excessive temperature, thus venting the vessel. <IMAGE>

Title: Modifying artwork masters for printed circuit boards
Inventor: CHANDLER NICHOLAS
IPC: G03F1/00
Filed: 1984-08-22
Abstract: Printed circuit board artwork masters may need modifying - for example, in order to make minute changes to track or gap dimensions. This can be done in a number of ways using the original master as an object to form a modified image on a fresh photographic emulsion, but all the known ways suffer from slight but significant disadvantages. The invention proposes a new approach to the known method in which a copy of the mask is prepared photographically by light irradiation through the mask onto a spaced photosensitive emulsion, in which new approach the source of irradiating light is a ring source, preferably one composed of a multiplicity of individual specular "point" sources. <IMAGE>

Abstract: An anti-reflection coating provides simultaneous anti- reflection properties at each of two separate waveband regions. The coating is a multi-layer stack having N number of first layers and N + 1 number of second layers, respective ones of the first and second layers being arranged alternately in the stack. Each first layer has a thickness of 0.25 lambda L and each second layer has a thickness of 0.25 lambda S where  lambda S and  lambda L are wavelengths which respectively lie in the two separate wavelength regions,  lambda L being greater than  lambda S. The N number of first layers have refractive indices which conform to a first relationship with the refractive index component such as would provide anti-reflection properties in the waveband region containing  lambda L in the absence of said second layers. The said N + 1 number of second layers have refractive indices conforming to a second relationship with the refractive index of the component such as would provide anti- reflection properties in the waveband region containing  lambda S in the absence of said first layers. Additionally, each second layer has a refractive index which provides optical matching with respect to the refractive indices of the media adjoining that second layer. <IMAGE>

Title: Two dimensional seismic modeling
Inventor: JOHNSON JAMES H
IPC: G01V1/32
Filed: 1986-08-28
Abstract: A method for producing a cross sectional plot e.g. on paper 26 having a synthetic time response compatible with real seismic data is accomplished by establishing a field for distance as one axis (x) and time/depth on the remaining axis (z) a computer 10 then displays a seismic section on a monitor (12) having corresponding dimensions from stored seismic data. Velocity information is then entered for the velocity between the surface of the earth and the first event desired to be plotted. A digitizing cursor (21) is placed on the field and a first point selected. The computer instantly calculates the location of the point and through ray tracing and Snell's law plots a visible line or point on the monitor. If the line or point does not fall on the event selected, then a new point is selected and viewed on the screen. The process continues until the line or point falls exactly on the event selected and then the process is repeated continuously along the event until the length of the monitor screen has been completed or until the interpreter is satisfied with the distance that he has covered. Additional events can be plotted using the same process. <IMAGE>
