Patent EP-0416673-A1 (EP)
Inventor: NOVOA PEREZ LIDIA INES
IPC: C07K19/00
Filed: 1990-08-02
Abstract: The present invention relates to the field of biotechnology and in particular the use of recombinant DNA technology for the production of heterologous proteins. 
     The technical object thereof is to develop a highly efficient method for the expression of heterologous genes in fused form in  E .  coli , which code for proteins which can easily be purified owing to the fact that they are synthesized in insoluble form in the cellular cytoplasm. 
     To achieve this, an expression vector is used which contains a stabiliser sequence which codes only for the first 58 amino acids belonging to the N-terminal end of the human protein interleukine-2, which is under the tryptophan promoter of the actual  E .  coli . This vector further contains the gene for resistance to ampicillin as a selection marker and the terminator of transcript ion of bacteriophage T4. In particular the genes which code for the antigenic proteins of the human immunodeficiency virus (HIV 1 and 2) were cloned therein, high levels of expression of said proteins being obtained from transformed strains of the bacteria  Escherichia coli . 
     The method which is the subject of the present invention can be employed for the expression at high levels of recombinant heterologous proteins synthesized in fused and insoluble form in  E .  coli , which can be used in the pharmaceutical industry to obtain vaccine preparations or in the development of diagnostic systems, in the food industry, in agriculture, etc.

Abstract: The present invention relates to a process for manufacturing in gas phase copolymers of propylene with 20 to 80% by weight of ethylene and/or 1-butene and optionally one or more C5 to C12 alpha-olefins. The catalyst used in the process is obtained by contacting a spherical MgCl₂ support containing an organic electron-donor D1 free from labile hydrogen with an internal electron-donor D3 chosen from aromatic carboxylic acid esters, and then with TiCl₄, the support having a well-defined diameter and a narrow particle size distribution. The process comprises in a first stage a prepolymerisation performed by contacting propylene with the catalyst and a cocatalyst consisting of a trialkylaluminium and/or of an alkylaluminium halide not complexed with an external electron-donor. In a second stage, the copolymer is obtained by contacting the prepolymer with an alpha-olef in mixture containing 20 to 80% by volume of propylene.

Abstract: Image scanning apparatus comprises a radiation source to generate a radiation beam, a support (1) on which an original image (2) is mounted in use so that the radiation beam is incident, in use, on the original image, the support and the beam being continuously movable relative to one another in a cyclic manner to expose successive scan lines on the original image. A detector (4) is provided for detecting the radiation beam after exposure to the original image. A buffer (6) receives image signals corresponding to a valid scan line of the original image at a first rate from the detector (4) during exposure of the scan line and outputs all the image signals corresponding to a valid scan line at a second slower rate to a processor (7) within one cycle of the relative motion between the support and the radiation beam. The buffer (6) is prevented from storing signals from the detector when a valid scan line of the original image is not being exposed.

Inventor: EISENLOHR GERALD
IPC: B65B69/00
Filed: 1990-04-03
Abstract: Apparatus for cutting cigarette packs transversely in preparation for recovery of the tobacco from the cigarettes therein comprises a first belt conveyor driven at a first velocity, a device for delivering the cigarette packs in collated relation onto the first conveyor with all packs resting on one of their larger sides and oriented lengthwise of the conveyor, and a second belt conveyor arranged coaxially with and adjacent to the downstream end of first conveyor to receive the packs from the first conveyor and driven at a second velocity, the second velocity being higher than the first velocity such that the packs become spaced apart end-to-end on the second conveyor. An indexing conveyor arranged orthogonally to and adjacent to the downstream end of the second conveyor receives each pack from the second conveyor at a receiving station. A photodetector detects the arrival of each pack at the receiving station and produces a signal indicative thereof. A stepper drive advances the indexing conveyor one step to move all packs thereon a selected distance greater than the width of the largest size pack in response to each such signal and then stops the indexing conveyor until the next pack arrives and is detected at the receiving station. A water jet cutter cuts each pack and the cigarettes therein transversely as they move along the indexing conveyor.

Abstract: An instrument for and method of effectively treating the prostatic urethra so as to relieve the symptoms associated with an enlarged urethra is disclosed. The tissue of at least selected portions of the prostate are compressed (preferably with a balloon inserted into the prostatic urethra so as to enhance hemostasis) and at least selected portions of the compressed tissue are directly irradiated (preferably with a laser beam transmitted from within the passageway in selected radial directions and moved along the prostatic urethra while exposing the tissue) so as to cause coagulation necrosis of selected portions of the compressed tissue so that as the tissue heals, the necrosed tissue slowly sloughs off during normal urination through the urinary tract so as to effectively remove the constricted portions of the prostatic urethra. Ultrasonic transducers are used from within the prostatic urethra to image the tissue as it is irradiated so as to monitor the procedure to insure proper exposure to the laser beam.
