Patent EP-0068111-A2 (EP)
Inventor: PIGGIN BRUCE PAUL
IPC: H01J9/04
Filed: 1982-05-05
Abstract: ositive photoresist technology is used on a sapphire substrate (7.1) carrying a patterned metallization layer (11.1) to expose areas (41.3, 41.4) of metallization within delineated apertures in the photoresist. Into these apertures needle-shaped triple carbonate particles (50.3, 50.4) are deposited cataphoretically normal to the metallization areas to form electron emissive areas. A further layer of photoresist is deposited to cover these areas and the first layer of photoresist and exposed through oversize mask so as to leave photoresist as encapsulation material (48.13, 48.14) covering the top and sides of the electron emissive material. 
     The encapsulated planar cathode structure is inserted into a multibeam cathode ray tube and heated so as to remove the encapsulation material.

Abstract: A food extruding device consisting of a casing for attachment to a conventional food processor, the casing including a food extrusion chamber 22 containing an extruder member 27 to which food to be extruded is fed through a vertically extended open ended tube 33 for extrusion through a die 30 which defines the cross sectional shape of the extruded material. The interior of the extrusion member 22 is formed with a spiral land 32 oppositely handed to the screw extruder 27. The extrusion chamber 22 is attached to the remainder of the casing 13 by means of a bayonet joint including interengaging lugs 23 and 24. The screw extruder 27 is driven by means of a worm gear 16 that makes driving connection with the driving shaft 12 of the food processor 10; this in turn drives the pinion 19, into the bore of which a shaft 29 driving the screw extruder 27, fits.

Abstract: A stereo or two channel electronic reverberation device is disclosed comprising an analog delay device which receives audio signals and provides delayed output signals at a plurality of outputs, with the time delay period of each output being different from thedelay period of other outputs. Two summing devices each receive inputs from different combinations of the analog delay device outputs to provide two different signals having different reverb components. An additional output delay device is also provided which receives the last output from the analog delay device, delays this signal a time period substantially greater than the time period between any two adjacent analog delay device outputs, and provides this substantially greater delayed signal to only one of said summing devices. The circuit includes a synthetic doubler which provides an output cyclicly varying in pitch from its input. Two output mixers provide reverb alone, doubler signal alone or both reverb and doubling. A timed turn on gate at the input of the analog delay device substantially eliminates unwanted noise signals of short duration.

Abstract: A vehicle wheel on which can be mounted a pneumatic tire which essentially includes rubber or rubber-like synthetic material, and has a carcass with load-carrying cords which are anchored in the bead regions of the tire via inextensible core rings. The wheel has a rigid rim with laterally outwardly disposed rim flanges; disposed axially inwardly of these rim flanges on the radially outer side of the rim are seating surfaces for the tire. To minimize disrupting effects on the tire tread, while at the same time improving the emergency operating conditions, a support member is disposed axially inwardly of the seating surfaces on the rim. This support member has a diameter which is greater than the diameter formed by the rim flanges. In the region of a given rim flange, the tire wall extends laterally outwardly from a given core ring in a substantially flat manner, and in particular in an angular range of from 0 DEG  to 20 DEG  relative to the axis of rotation of the tire. The carcass neutral line passes through the same region of a given rim flange in such a way as to avoid a turning point. The core rings are eccentrically disposed in their head regions in such a way that when the tire is mounted, the inner diameter of the tire in these bead regions is less than it is during mounting of the tire.

Abstract: The longitudinally compressive and tensile proportionality limits and ultimate strengths of an elongated structural member are increased by applying to the member a longitudinally compressive load which is close to its maximum load. In order to prevent buckling of the member under such a load, the member is confined in an encasement which allows the member to yield longitudinally without bending. By applying to the member a longitudinally compressive load much greater than the member's original (i.e. untreated) ultimate compressive strength, both the ultimate strengths and the proportionality limits of the member are increased. In addition, application of a longitudinally compressive load close to or greater than the original ultimate compressive strength of the member also increases the straightness of the member and frees the member of residual stresses.

 in a further step, the remaining carbamate is removed in the form of a gas mixture containing ammonia and carbon dioxide, and this gas mixture is processed to form a solution of ammonia and carbon dioxide in water,
 and the remaining urea-containing solution is processed to form a concentrated urea solution. 
<??>The urea solution to be concentrated is introduced into the tubes of a shell and tube heat exchanger, the gas mixture from the second decomposition step is led into the shell side of heat exchanger at the end opposite the place where the urea solution to be concentrated is fed, the solution of ammonia and carbon dioxide in water is fed to the said shell side at a place located between the inlet for the gas mixture and the inlet for the urea solution to be concentrated, and the condensate is discharged from the shell side at the end where the urea solution is led into the tubes.

Abstract: A method of operation is provided for a fast comparator 10 which contains multiple series-connected, single-ended gain stages 113, 115, 117, 119). High resolution comparison is possible due to the reduction in offset by this method of operating the comparator. The offset of the first gain stage (113) is made to dissappear by placing it in an open loop mode prior to the turning on of the successive single-ended gain stages. The errors of successive single-ended gain stages are made to appear of less consequence because they are reduced by the inverse of the open loop gain of the upstream stage.

Abstract: @ An improved method of melting metal scrap in a molten melting media is disclosed. The method comprises the steps of providing a body of molten melting media (74) in a housing (36) having an upper portion (78) and a lower portion (76), the lower portion (76) having a generally cylindrical wall section. A supply of metal scrap (72) is added to the housing (36) and a supply of molten melting media (74) is introduced to the upper portion (78) of the housing (36). Melting of the metal scrap (72) is initiated by ingesting it and molten melting media (74) downwardly in the housing (36) by action of an impeller (73) positioned in the lower portion (76), the impeller (73) having a flat ring member (90) having an opening in the center thereof and having blades (94) extending from said ring member (90) to a substantially circular disc member (92). The scrap (72) and melting media (74) enter the opening in the ring member (90) in an axial direction and are propelled therefrom in a radial direction by use of the blades (94). The impeller (73) is positioned in the cylindrical wall section such that at least the ring member (90) cooperates therewith to move the scrap (72) and melting media (74) from the upper portion (78) through said impeller (73) while substantially avoiding recirculation of the molten melting media (74) within the housing (36) to the upper portion (78).
