Title: Prorennin c dna containing rrecombinant plasmid and microorganism containing same
Inventor: BEPPU TERUHIKO
IPC: C12N1/20
Filed: 1982-08-23
Granted: 1998-12-15
Abstract: Messenger RNA of prorennin is extracted from the fourth stomach of calf and the double-stranded prorennin cDNA is prepared therefrom.  The prorennin cDNA is cloned into a host microorganism, E. coli C600r~m~, to give clones containing the cDNA insert with variable size as confirmed by the base sequence determination in addition to the colony hybridization and hybrid-arrested translation technique.  In vitro recombination of two plasmids obtainable from these clones, pTACR102B6 and pTACR103C2, affords plasmid pCR1001 containing the whole coding sequence for prorennin.  On addition of the lac operon of E. coli to pCR1001, plasmid pCR2001 is prepared, which plasmid contains the prorennin cDNA sequence and the promoter requisite for the expression of the prorennin gene in a host cell.  Transformation of E. coli C600r~m~ by inserting pCR2001 produces a new E. coli strain, E. coli CR1 fully designated as E. coli CR1(r~m~, thr-, leu-, thi-, pCR2001).  This genetically engineered new strain of E. coli, when propagated in aqueous nutrient media, produces prorennin.  Thus production by bacteria of prorennin which is a proenzyme and a precursor of the milk coagulating enzyme, calf rennin, has now been accomplished.

Abstract: ABSTRACT         In a rail fastening for use with concrete ties a two piece self-retaining shoulder block is employed.   Shoulder blocks of varying types are well-known in the art, but those generally employed for use with concrete ties are one piece shoulder blocks embedded within the tie.  The problem with the presently used shoulder blocks is that when a concrete tie becomes worn and must be changed it is necessary to dig out the crib bed to allow the tie to be lowered such that it may clear the shoulder block in order to be removed out from under the rails.          The present invention overcomes this difficulty by providing a two piece shoulder block whereby the top portion is removed so that the tie may be pushed out directly without disturbing the crib bed.

Abstract: DISTRIBUTED CONTROL OF ALIAS NAME USAGE IN NETWORKS Abstract of the Disclosure Computer systems linked to nodes in a com-munication network communicate directly with each other to establish name associations for entities (e.g. programs, storage files, etc.) susceptible of being shared across the network, and thereafter communicate further by names (rather than addres-ses) to establish sessions (i.e. logical connec-tions over the network) between entities. Each system maintains a table of names assigned to locally accessible entities. The name and session establishment processes are architected to avoid dependence on any "central" or "master" system, and to allow for extension of communications relating to these processes across devices linking portions of the network associated with different communica-tion media or channels.

Abstract: STANDING SEAM STRUCTURE COVERING SYSTEM             ABSTRACT OF THE DISCLOSURE A standing seam system includes parallel, elongate panels having first and second upstanding, interconnected edges forming a standing seam.  The edges include spaced-apart upstanding portions and outer end portions.  The outer end portions are folded together to form a lockseam.  The outer surfaces of the lockseam and upstanding portions are generally coplanar to pro-vide a uniform appearance and effectively conceal the lockseam.  A portion of the panel between the pan sec-tion and the second edge is formed to create an upwardly extending bi-fold interior hem in the space between the first and second edges.  This interior hem is engaged by brackets secured to the structure at appropriate positions to anchor the panel to the structure.  Since the brackets only extend part way up the edges and do not extend into the lockseam, the lockseam is smoother and much more water tight than it would be otherwise.

Granted: 1992-05-19
Abstract: ABSTRACT OF THE DISCLOSURE:             There are disclosed a process and a plant for gasifying biomass. The plant has a pressure vessel containing a hot fluidized sand bed. The bio-mass is pre-dried to a moisture content of from 10% to 35% by weight. A stream-free oxygen-containing gas is fed and distributed, through a grid system at the bottom of the  hot sand bed, to hold the bed in a fluidized state and to form, in its lower portion, an oxygen-rich heat-forming combustion zone and, in its upper portion, a hydrogen-rich gas-forming pyrolysis zone. The pre-dried biomass is uninter-ruptedly fed in the pyrolysis zone at essentially the center of the hot fluidized bed, this center being deter-mined when the sand bed stands at rest. The fluidized bed is held at an operating temperature of 750 to 860° C under an operating pressure of 400kPa to 1750kPa by control-ling the feeding rate of the fluidized gas aswell as the feeding rate of the biomass. The gases and biomass residue-released from the hot fluidized bed are removed in a gas stream from the head space above the bed and sent to a primary cyclone which separates the useful gases from most of the biomass residue  the latter being returned to the combustion zone of the bed. The gases and the biomass residue that have remained in the first cyclone are then moved into a second cyclone where the useful gases are collected and the biomass residue dis-carded.

Abstract: ABSTRACT OF THE DISCLOSURE An improved conveyor drive unit (150) with a method of operation thereof, which can be rapidly and easily mounted on a roller-type conveyor system and which, when arranged in  series,  can  be  sequentially  stopped  and  restarted relative to predetermined parameters in the article flow along a conveyor path (56). In one embodiment, each drive unit  (150)  has an arm  (52)  which extends at a desired distance over an article conveyor path (56) which can be tripped at the occurrence  of accumulation.  A pneumatic valve  (68)  is  operably  coupled  to  the  arm  (52)  for releasing  air  into  an  actuating  cylinder  (78)  having operably coupled thereto a shifter rod (92). The shifter rod  (92)  is axially displaced by the actuating cylinder (78) which in turn releases a drive collar  (102) from a keyed sprocket of the pinion gears  (18)  of a transfer mechanism or "module" (1) of the conveyor system. When the drive  collar  (102)  is  disengaged,  the  operation  of transport mechanism or module  (1)  is thus halted.  When normal article   flow is to be resumed,  the drive collar (102)  is  engaged  to  the  sprocket  and  the transport mechanism or module  (1)  is restarted. Instead of an arm (52) operable coupled to the pneumatic valve (68), article sensing (180), counting and timing (218) devices operably coupled to solenoid valves (192) are used in other embodiments.

Abstract: ABSTRACT     Poly(diethylene glycol-4,7-dinitrazadecane-dioate), (P-DEND), is synthesized by the Michael addition of ethylene dinitramine to methyl acrylate to yield the intermediate compound dimethyl-4,7-dinitrazadecane-dioate (DMDND).  DMDND is reacted for a period of about 18 hours with diethylene glycol (DEG) at about 85°C in presence of a p-toluenesulfonic acid catalyst to yield P-DEND.  The product (P-DEND) is purified by passing it through a silica gel column using methylene chloride as solvent.  The average molecular weight of P-DEND ranges from about 1500-2000.          P-DEND is shown to be compatible with stabilized nitroglycerin for use as an energetic polymer binder for high performance propellants.
