Patent EP-0280525-A2 (EP)
Inventor: ROBBINS EDWARD S III
IPC: B29C48/00
Filed: 1988-02-24
Abstract: A method of forming a plastic product having contoured peripheral edges molded in a continuous in-line manner is described. A bounded recessed region is defined on at least a portion of a pattern roll's cylindrical surface. The pattern roll is then rotated in opposition to a platen roll so as to define a nip therebetween. Discrete volumetric portions of the recessed region are thus sequentially continuously presented at the nip upon rotation of the pattern roll. A molten thermoplastic is simultaneously extruded into the presented volumetric portions. Thus, this extrusion/rotation causes the thermoplastic material to fill the presented volumetric portions of the defined region, which filled portions will eventually form an outline of the plastic product and will, moreover, cause the thermoplastic material to be flowably compressed in the defined nip. This compression, in turn, allows the contoured edges to, in effect, be molded for each sequential volumetric presentation of the bounded region. Pattern rolls for practicing this method and a method of forming the same are also disclosed.

Abstract: In order to make a superconductive electric wire the hollow space within a sheath is filled with green materials of a superconductive material of e.g. A - B - Ca - O (where A and B are at least one element from groups IIIa and IIa respectively of the periodic table). The diameter of the sheath and green material is then reduced, and the result heat treated in an oxygenous atmosphere at a temperature of 800 to 1100°C for between 1 and 300 hours. This gives a supercondition wire with a high critical temperature and a high critical electric current density.

Abstract: The present invention relates to synthesis of HBsAg in yeast. Yeast expression vectors comprising a yeast promoter, ADHl, have been constructed. The region of the HBV genome coding for the S-protein, excluding a possible 163 amino acid presequence, has been transferred to the yeast expression vector. 
     Using the described yeast vector, the successful synthesis of HBsAg by yeast has been achieved. The product is antigenic (reactive with anti-HBsAg) , and a substantial portion is found associated with particles identical in electron microscopic appearance to those found in the serum of HBV-infected patients and in Alexander cells but having a smaller particle size diameter. The HBsAg   synthesized by yeast has identical sedimentation behavior to purified, naturally-occurring HBsAg particles purified from Alexander cells as measured by sucrose gradient sedimentation. The present invention demonstrates synthesis and assembly of a higher ordered multi-component structure resulting from expression of a heterologous DNA coding segment in a microorganism.

Abstract: Die Erfindung beschreibt einen Hochfrequenz-Leistungsoszillator mit einem als Komplementär- oder Quasikomplementärstufe aufgebauten Leistungsverstärker (1), der im Schaltbetrieb arbeitet, und der eine Lastimpedanz (Zlast) über ein aus einem Serienresonanzkreis (Rs,Ls,Cs) und einem Parallelresonanzkreis (Cp,Lp) gebildeten Ausgangsfilter speist. Die Steuerspannung für den Leistungsverstärker (1) wird aus dem Ausgangsfilter gewonnen. Dabei wird ein erster Teil (Uu) der Steuerspannung aus der am Parallelresonanzkreis anliegenden Spannung (U2) abgegriffen, wobei dieser erste Teil (Uu) Spannungsrückkopplung verursacht, und ein zweiter Teil (Ui) der Steuerspannung wird aus dem im Serienresonanzkreis fließenden Strom (I1) gewonnen, wobei dieser zweite Teil (Ui) der Steuerspannung Stromgegenkopplung verursacht. Diese beiden Teile der Steuerspannung werden in einem Additionsglied (5) zusammengefaßt und über Impulsformerstufen (6) dem Eingang des Leistungsverstärkers (1) zugeführt. Dadurch entsteht eine gemischte Spannungsrückkopplung und Stromgegenkopplung. Der Vorteil gegenüber einfach spannungsrückgekoppelten Leistungs-Oszillatoren ist eine deutliche Erhöhung der Betriebssicherheit.

Abstract: A flat panel type display comprising control electrodes each divided in the horizontal direction of the screen thereof and arranged in a vacuum casing, fluorescent material provided on each control electrode, mesh-like electrodes facing the fluorescent material, vertical scanning electrodes each facing the mesh-like electrodes and divided in the vertical direction of the screen thereof and an electron source for generating a plurality of electron beams continuously or discretely in the extension of space between a light emitting portion composed of the fluorescent material and a group of the vertical scanning electrodes in the horizontal direction of the screen thereof. Further, a partition made of insulating material is provided in the divided portion of each control electrode to increase the withstand voltage between each pair of the adjacent control electrodes, and a modulation signal is supplied to each control electrode. Alternatively, every n pieces of the control electrodes are connected to a bus to which a pulse voltage for causing the fluorescent material to emit light is applied. Furthermore,   to a first vertical scanning electrode in the side, where an electron beam going straight on is incident, is applied a voltage, of which the magnitude (V D ) is equal to a voltage applied to the fluorescent screen or the mesh-like electrodes. Then, to a predetermined number of the vertical scanning electrodes subsequent to the first vertical scanning electrode in the direction in which the electron beam goes straight on, is applied a voltage of which the magnitude (V D  -V CC ) is less than the voltage applied to the fluorescent screen. Thereafter, to a vertical scanning electrode subsequent to the predetermined number of the vertical scanning electrodes in the direction in which the electron beam goes straight on, is applied a voltage of which the magnitude (V D  - V M ) is equal to or more than the voltage applied to the fluorescent screen or the mesh-like electrodes. Thus, the vertical scanning is performed.

Abstract: The method consists in using three pictures (1, 2, 3) on transparent supports representing dissociated elements of the set of elements constituting an advertising message, which are arranged on these pictures in order that the message should be reconstructed by superposition thereof and in projecting them onto a screen by means of a projection system in which they are displaced along different paths overlapping within a superposition zone (4), and in order to cause them to pass periodically within this zone. An apparatus devised to carry out this method comprises three picture-carrying panels which are displaceable by translation to and fro continuously by means of a transmission of the connecting rod type which is continuously driven by a motor. The advertising message is thus shown alternately and progressively from a dissociated conformation of its elements to a reconstructed conformation and/or vice versa. <IMAGE>
