Patent EP-0089626-A2 (EP)
Inventor: BREWER STEPHEN JAMES
IPC: C12P21/02
Filed: 1983-03-17
Abstract: method for the production of polypeptides utilizing a polymer of charged amino acids and an exopeptidase. A DNA sequence coding for the charged amino acid polymer is inserted adjacent to one end of the polypeptide gene. The polypeptide-charged amino acid polymer fusion product is removed from most contaminents by selecting for the charged amino acid polymer during a first isolation step. Next the charged amino acid polymer is hydrolyzed using an exopeptidase which leaves the polypeptide active. A second isolation step removes the polypeptide from any remaining contaminents. An example using polyarginine and carboxypeptidase B to produce urogastrone is included.

Abstract: A punch is pressed on a blankpiece into a die. The die is filled with liquid therein, whereby hydraulic counterpressure is generated by said pressing. The pressed blankpiece is forcibly followed in shape around the punch by hydraulic counterpressure, while part of the hydraulic counterpressure is automatically supplied to an outer circumference of the blankpiece via bypath passage. In case, the blankpiece is a plate, said supplied hydraulic pressure serves as compression force from the outer circumference of the flange to the radius direction. In case, the blankpiece is a product formed by a first drawing, said pressure serves as pressing force toward axial direction of a side wall of the product. When the supplied hydraulic pressure flows out from a space between the punch and a blank holder, the liquid serves as lubrication on an upper and lower surfaces of the blankpiece.

Abstract: A method and means for drying a thin aqueous-based coating on heat sensitive materials without boiling and without distortion or damage to the heat sensitive material or delicate surface thereof. Solvent-based adhesives are used in the production of articles of manufacture because of the ability to assemble the separate pieces immediately after the spray adhesive is applied. However, certain solvent-based adhesives attack the surface of the item to be covered, and in the case of videodiscs, the solvent in the adhesive may well contaminate the plastic surfaces or even the aluminum reflective layer of a laser disc. According to the present invention, a water based coating applied to a sensitive material is subjected to alternate sources of radiant heat energy and relatively cool air. The time of exposure to each source and the amounts of heating and cooling of the respective sources are maintained at levels sufficient to significantly decrease the time needed to dry the coating while limiting the temperature increase of the material to a level insufficient to deform or distort the material or surfaces thereof.

Abstract: An apparatus is disclosed for feeding a continuous supply of carbonaceous material into a pressurized reactor for producing a product gas from the material and which contains toxic and flammable gases. The apparatus comprises a first rotary gas lock (13) for receiving the material from ambient atmospheric condition. The first lock (13) is supplied with a flow of nitrogen as a sealing gas to prevent air from entering the lock and the apparatus. The first lock (13) transfers the material to a second rotary gas lock (14) which in turn transfers the material to a screw conveyor (42) for delivery to the interior of the reactor. The second lock (14) is supplied with a flow of a clean product gas as a buffer gas. The clean product gas supplied to the second lock (14) is at a pressure greater than the pressure in the reactor and prevents flow of gases from the reactor to the apparatus. An exhaust (51) is maintained between the first and second locks which draws off nitrogen and clean product gas with the nitrogen and product gas constituting a noncombustible mixture of gases in the exhaust. Means are provided for preventing entrainment of particulate material between the first and second gas locks.

Abstract: A pressure regulating valve for controlling pressure in high pressure hydraulic circuits includes a closure member 36 with an integral control piston 33 and a conical seating surface 38 cooperable with a complementary surface on a seat member 39. The valve closure member is biased in the closed position by an actuating mechanism including a pressure gas piston 88 and cylinder 72 arrangement utilizing a flexible diaphragm 90 for sealing the actuator pressure chamber 96. The effective cross-sectional area A3 of the control piston is large enough to minimize the differences in cross-sectional areas on the closure member exposed to pressure fluid between the valve closed and valve open positions whereby a minimum variation between the valve opening pressure and the control pressure is experienced. The increase in pressure in the actuator pressure chamber 96 resulting from movement of the valve from the closed to open positions substantially offsets the change in effective face areas of the closure member to further minimize the difference between the valve opening pressure and the steady state regulated pressure.

Abstract: A tamper evident closure and package having a container (10), a resealable, substantially rigid closure (12) for closing, opening and reclosing the container (10),. color changing means (32a in Figures 1-6) which effect a color change upon stretching, and coacting mechanical means (24, 36,44 and 46 in Figures 1-6) for uncapping and recapping the closure 10 and for stretching the color changing means (32a) which clearly and unequivocally indicate the condition of the package, e.g., open or closed. 
     Where legends, or other well defined indicia, indicating opening is desired, the color changes can be localized in the skirt by providing thin sections (32a) which stretch preferentially and adjacent thicker sections (38) which remain substantially unstretched. The thin sections (32a) for example can be a legend, or alternatively the thick sections (38) can be the legend while the thin sections (32a) provide a suitable background. 
     The colour changes employed by the invention can be accomplished by such phenomena as stress whitening inherent in various plastic materials. Alternatively, the color changes can be accomplished by mechanisms such as the use of encapsulated staining or coloring agents incorporated in a suitable matrix.

Abstract: @ In an optical fibre receiver, the modulated light falls on a p-i-n diode (PD) connected to the input of an operational amplifier (A). This amplifier is shunted by a load resistor (R), which in turn is shunted by a non-linear Schottky diode (SD). This prevents a large pulse from spoiling the sensitivity of the receiver to a following smaller pulse. 
     This also provides the receiver with a low pass response having a relatively long time constant. In addition to this, the a.c. coupling response for the connection to the next stage of the system has a relatively short time constant. These two time constants combine to give an overall characteristic with a relatively narrow bandwidth, which enhances the above effect. 
     Finally, when the line muting function is needed, as between messages, the bit stream as detected includes a double amplitude pulse whose detection initiates the line muting function. This can be implemented by a double length pulse included in the bus bit stream which is so detected as to give a double amplitude pulse.

Abstract: An X-ray tube has a cathode, a grid, a perforated anode and a target, arranged behind the perforated anode, with an exit window on the side for the X-ray radiation. In addition, two deflection coils, in each case connected to an AC voltage source, are provided for lateral deflection of the electron beam in two planes. The response and frequency of the output voltages or output currents of the AC voltage source are dimensioned such that the impact point of the electron beam on the target flows through closely adjacent tracks, like the electron beam of a television tube, and thus sweeps over an area on the target which is turned towards the exit window as a macro-focus spot. By forming such a macro-focus spot by deflection of a micro-focus spot, an even intensity distribution is achieved over the complete extent of the macro-focus spot. <IMAGE>
