Abstract: ABSTRACT OF THE DISCLOSURE           The disclosed windshield wiper assembly includes a squeegee, a backing element operatively connected to the squeegee, and a superstructure which is removably connected to the backing element and adapted to be connected to a wind-shield wiper arm for urging the squeegee towards the wind-shield.  The superstructure consists of an elongated primary yoke having a pair of spaced free ends; a pair of secondary yokes are respectively pivotally mounted on the free ends of the primary yoke and have pairs of opposed cooperating claws formed thereon for releasably engaging the backing element.          In a presently preferred embodiment, the primary and secondary yokes each have a generally triangularly shaped transverse cross section, through substantially their entire length, defined by a pair of inclined longitudinally extending side surfaces and a substantially flat base which extends parallel to and in spaced relation from the backing element.  The side surfaces of the primary and secondary yokes present inclined pressure surfaces to an air stream moving over the surface to be wiped whereby downward components of force are produced on the yokes to increase the downward pressure on the squeegee.          The backing element includes specially formed embossments located outwardly Or the superstructure to provide stops for engagement with generally complementary shaped portions of the claws on the secondary yokes to prevent inadvertent removal of the backing member and squeegee from the super-structure.

Abstract: L'invention concerne un briquet à gaz liquéfié sous pression, du type comprenant dans un boitier, un réservoir muni d'une valve aboutissant à un brûleur, et un mécanisme d'allumage comportant une molette, une pierre repoussée contre la molette et des moyens de commande de valve actionnés par le mouvement d'un chapeau de fermeture du boitier grâce à un ressort dont une première partie est reliée au chapeau pour le maintenir d'une part en position ouverte, d'autre part en position fermée, et une seconde partie, susceptible d'être déplacée par le déplacement de cette partie reliée au chapeau, coopère avec la valve pour couvrir la valve lors du mouvement d'ouverture du chapeau. Ce briquet est caractérisé en ce que le ressort comporte, outre les première et seconde parties, une troisième partie de préférence centrale, coopérant avec la pierre pour la repousser contre la molette. Cette disposition est particulièrement avantageuse puisqu'elle permet de diminuer ou même annuler la pression du ressort sur la pierre lorsque le chapeau est en position fermée, ce qui augmente sa longévité.

Abstract: ABSTRACT OF THE DISCLOSURE           Acoustic signals emitted by systems under pressure or stress are detected by acoustic sensors placed on the structure and the detected acoustic emissions are processed and analyzed to determine the presence of any defects in the structure, their location and significance.  The sensor comprises a relatively small diameter transducer which can be bonded at appropriate locations on the surface of the system being tested. After being used, the transducers can be removed and reused again.  Each transducer comprises a machined metal casing which includes a combined lens wearplate which is unitary, that is integral, with the casing and a detecting element such as a piezoelectric crystal bonded to the inner surface of the lens wearplate.

Abstract: ABSTRACT OF THE DISCLOSURE                A radiation sensitive plate comprises a metallic substrate having a surface coated with a radiation sensitive layer comprising a quaternary ammonium salt. The quaternary ammonium salt is of the type which will accept at least one electron on exposure to radiation to form a substance capable of causing metal to be deposited onto said substance from an electroless plating solution in contact with said substance and comprising a salt of said metal and a reducing agent.  The layer may include a chemical sensitiser, a spectral sensitiser, a polymeric binder, a surface active agent and/or a development accelerator.           The preferred chemical sensitisers are aryl substituted glycollic acids or salts or ethers of such acids, A lithographic printing plate is produced by image-wise exposing the plate, contacting the plate with an electroless plating solution and, if necessary, rendering the resultant image areas more oleophilic and the resultant non-image areas more hydrophilic.

Abstract: ABSTRACT OF THE DISCLOSURE     Solid and/or dissolved contaminants are separated from a polar liquid such as water by providing in the contaminated, acidic liquid medium a galvanically charged particulate dispersion of defined size, concentration, density and free surface energy, and then flowing such loaded medium through successive oxidation and treatment zones of an electrically insulated apparatus at a rate defined by dimensionless parameters such as Reynolds numbers, etc., so as to prevent phase separation. Gaseous oxygen adheres to particle surfaces and oxidation is further promoted by bringing medium to pH 2.0 to 2.5 as with sulfur dioxide gas, plus exposure to action of heavy-metal ions such as ferrous/ferric.  After air blowing, medium is neutralized and brought to pH 10-11 with continuous aeration of suspended flocculant, then treated with soda ash and optionally additional particulate (recycled sludge), and the contaminant matter then allowed to precipitate with concurrent galvanic grounding of the medium. The dispersed particulate matter may be inert and deliberatly added (e.g., shredded cellulose) or it may be produced In situ by fractionation of component debris as in sewage-refuse; when possible, as in the latter case, the particle itself is subse-quently oxidized.  In either event, dual end products are potable water and sterile sludge. Dissolved salts such as sodium chloride are simultaneously removed from, medium as component of sludge; applicable to remove toxic components from cooling water systems, recover traces of precious metals, etc., from slurry or run-off liquid, brackish water, industrial waste, etc.     Suitable treating apparatus is also provided.

The slurry is separated into a solid sediment containing the minerals and a part of the organic components of the liquid and a concentrated mother liquid, at least a portion of which is combusted as the concentrate.  By drying the sediment with agitation, a granulate which can be used as a fertilizer can be produced.          The polluting effects of discharge of the waste liquid are eliminated and a useful product formed.  Apparatus for effecting the process also is disclosed.
