Title: Method of lining a pipe
Inventor: MAINE LESLIE
IPC: B29L23/00
Filed: 1993-01-27
Abstract: A method of lining a pipeline (24) intended to carry gas, oil, water, sewage or chemicals in which a cross-linked polymeric liner pipe (10), which has been reduced from its original diameter to a lesser diameter or to a shape of reduced maximum dimension, is pulled through the pipeline (24). The lesser diameter is less than the least inner diameter of the pipeline (24). After the liner pipe (10) has been fully pulled through, the pipe liner (10) is heated by means of a source (60) of visible or infrared radiation forming part of a pig assembly (50) to cause it to revert to the pipeline.  The pig assembly or assemblies are stationary at zones (70) where service connections are to be made.  Subsequently, the remaining liner pipe (10) is reverted by pulling the source (60) through the liner pipe (10).

Abstract: The invention relates to a tamper-evident closure cap for a container having a neck and an opening defined in the  neck.  The  closure  cap of  the  invention  comprises  an annular skirt member adapted to be secured to the neck of the container to prevent removal of the  closure  cap  from the container,  and a closure member hingedly connected to the skirt member for pivotal movement between a closed position whereat  the  closure  member  closes  the  opening  of  the container and an open position whereat the closure member provides access to the opening, the closure member having a top planar portion extending in a first plane. A manually graspable tab is fixedly connected to the closure member for moving same from the closed position to the open position.  The closure cap further includes a tamper-indicating member removably connected to the skirt member in overlying relation with  respect  to  the  tab  and  adapted  to  prohibit  initial opening of the closure member prior to removal of the tamper-indicating member.  The tamper-indicating member comprises a manually graspable tongue portion and at least one elongated attachment portion extending between the closure member and the  skirt  member  and  detachably  connected to  the  skirt member,  the tongue portion and the at least one attachment portion being co-planar and extending generally in the first plane.  Thus,  unauthorized removal of the  tamper-indicating member provides  evidence  of tampering or  initial  opening. since,  according  to  the  invention,  the  tamper-indicating member is disposed in overlying relation with respect to the opening means, it is impossible for an unauthorized user to move the closure member from the closed position to the open position without first removing the tamper-indicating member and thus without providing evidence of tampering or initial opening.

Title: Engine misfire, knock or roughness detection method and apparatus
Inventor: KLAUBER ROBERT D
IPC: B60G17/019
Filed: 1991-12-10
Abstract: A method and apparatus for comparing torsional stress/strain states of a power transmitting member of an internal combustion engine to detect an abnormal combustion condition, including misfire, knock or roughness. Statistical processing steps may be used to detect an abnormal combustion event including: calculating a mean and standard deviation for a set of signals related to the torsional stress induced in the power transmitting member, calculating a difference between a later signal and the mean, calculating a ratio of the difference to the standard deviation, and comparing the ratio to a threshold. The ratio so obtained from a given cylinder may further be compared with one or more other such ratios from other cylinders. In other words, the autocorrelation and/or cross-correlation techniques may be used. A magnetostrictive sensor may preferably be used to obtain the signals relating to the torsional stress in the power transmitting member, such as the engine crankshaft. In addition, the magnetostrictive sensor may include windings to cancel induced electromagnetic interference signals. The magnetostrictive sensor may also generate signals relating to the position of the power transmitting member in addition to the torsional stress in the power transmitting member. Spatial integration techniques may be used to obtain torsional stress/strain signals which are independent of the rotational speed of the power transmitting member. Spatial interaction may be performed using variable amplifiers, variable attenuators, switched capacitors or other techniques.

Title: Process for the removal of species containing metallic ions from effluents
Inventor: YANNAI SHMUEL
IPC: C12R1/85
Filed: 1993-12-01
Abstract: ABSTRACT OF THE INVENTION            A process for the removal of species containing  metallic ions from effluents by yeast cell walls is described. The yeasts used are selected  from  Saccharomyces  cerevisae, Saccharomyces   uvarum   and   Saccharomyces  lipolytica. According to the process, the washed yeast cell walls are first  treated  by  a  water  soluble  aldehyde and after sorbing the metallic ions, the yeast cell  walls  may  be, regenerated by a mineral acid or a chelate solution such as ethylene-diamine tetraacetic acid, releasing the  sor-bed metal ions. Acccrding to a preferred embodiment,water containing acetone or alcohol is  used  for  washing  the yeast cell walls. The sorption by the yeast cell walls is carried out at a pH in the range of 1 to 13 and preferab-ly in the range of 4 to 7. The most preferred aldehyde is selected from formaldehyde and glutaraldehyde or any mix-ture  thereof.  The metal sorption process may be carried out batchwise or continuously. In the continuous process, the  yeast  cell walls are immobilized on a porous glass, purified sand or polymers.

Title: Endochitinase gene induced by osmotic stress and abscisic acid isolated from the wild tomato lycopersicon chilense dun
Inventor: TABAEIZADEH ZOHREH
IPC: C12N15/56
Filed: 1993-12-06
Abstract: Two osmotic stress- and ABA-responsive members of the endochitinase  (EC  3.2.1.14)  gene  family  has  been isolated and identified from leaves of drought-stressed Lycopersicon chilense plants. The 966-base-pair insert of pcht28 encodes an acidic chitinase precursor with an amino-terminal signal peptide. The mature protein is predicted  to have  229  amino  acid  residues  with  a relative molecular weight of 24,943 and pI value of 6.2. The same number in amino acids, molecular and PI value are predicted for the protein encoded by pchtI, despite of  a  slight  variation  in  the  DNA  and  amino  acid sequences.  Sequence analysis revealed that pcht28 and pchtI have a high degree of homology with class II chitinases (EC 3.2.1.14)  from tobacco. Northern blot analysis indicated that these genes have evolved a completely different pattern of expression from others reported thus far.  They are highly induced by both osmotic stress and the plant hormone abscisic acid. Southern blot analysis of genomic DNA suggested that the pcht28- and pchtI-related chitinase is encoded by a small multigene family in this species. Knowing the role of plant chitinase  in plant defense against fungal pathogens,  it is assumed that, besides their general defensive  function,  the  pcht28-  and  pchtI-encoded chitinases may play a particular role in protecting plants from pathogen attack during water stress.
