Abstract: L'invention concerne une couche à jeter, notamment pour adulte incontinent, constituée d'un tampon plat absorbant, de forme rectangulaire, pourvu de dispositifs d'attaches, le tampon étant recouvert sur sa face externe d'une feuille imperméable et, sur sa face interne en contact avec la peau de l'utilisateur, d'une feuille perméable en non-tissé. La couche a une zone arrière et une zone avant et des bourrelets sont présents à proximité de chacun des bords longitudinaux. La couche à jeter selon l'invention est caractérisée en ce que les dispositifs d'attaches sont formés de deux ceintures élastiques et en ce qu'avant utilisation une des deux ceintures élastiques, constituée d'une bande élastique munie à chacune de ses extrémités d'une pince, est fixée au niveau de la zone arrière sur l'un des bords longitudinaux de façon à ce que la pince utilisée enserre le bourrelet, et l'autre ceinture, similaire à la première, est fixée sur le même bord longitudinal au niveau de la zone avant de façon à ce que la pince utilisée de la seconde ceinture enserre également le bourrelet. Ce dispositif améliore l'étanchéité de la couche et facilite sa mise en place par l'utilisateur.

Abstract: ABSTRACT OF THE DISCLOSURE   A replaceable spindle locking system for a power tool enables an operator to replace a lock member without disassembling the tool.  An externally-accessible retaining member, such as a washer,, is trapped between a ledge located in a housing recess and a shoulder formed on the lock member, which is normally spring-biased out of engagement with a driven member.  The coaction of these elements simultaneously and releasably normally retains both the lock member and the retaining member connected to the housing.  When it is desired to replace the lock member, the operator depresses the lock member against the urging of the spring until the lock member is out of retaining engagement with the retaining member. Then the retaining member is slideably moved out of engagement with the lock member, thereby allowing the operator to quickly remove it.

Abstract: ABSTRACT            A process for purifying lactulose from other carbohydrates, in particular from lactose and galactose, by passing a lactulose syrup through one or more columns containing a bifunctionalised boron resin of the type:                                 (I) in which ?  is a polyacrylic or polystyrene polymer matrix and R, R1, R2, R3, X are as defined in the text.            By passing the lactulose solution containing carbohydrate impurities through a boron resin (I) of polyacrylic matrix, the lactulose is selectively retained and is subsequently released by elution with an acid solution.            The small quantity of galactose which may still be contained in the lactulose-enriched solution can be removed by passing said solution through a boron resin (I) of polystyrene matrix, which selectively retains the galactose.

Abstract: Abstract:   In an insertion machine a track moves groups of items past feed stations during respective machine cycles.  The feed stations selectively feed items onto the track for inclusion with a group of items and eventual stuffing into an envelope to which postage need be applied.  A master control item fed from station for each group has an indicia thereon which provides an indication from which of the feed stations items can be fed.  In order for data processing means to calculate the amount of postage appropriate for the stuffed envelope, an operator uses a keyboard and display to input predetermined per item weight values for items held at select stations. A data processor uses the predetermined values indicative of the per item weight of items held in the stations to obtain a calculated indication of total weight for each group of items.  Some of the feed stations contain optional items which are to be selectively included with a group of items if the data processor determines that the inclusion does not increase the postage amount for the group.

Title: Decoder for extracting a 4:3 aspect ratio signal from a high definition television signal

Abstract: ABSTRACT A DECODER FOR EXTRACTING A 4:3 ASPECT RATIO SIGNAL FROM A HIGH DEFINITION TELEVISION SIGNAL          In a television receiver, a demultiplexer (400) for a high definition multiplexed analog component tele-vision signal          has line stores (411 to 414) for storing samples of each component signal.  A selection code decoder (422) produces a code (220) selecting a group of samples for each component signal according to the aspect ratio of the television receiver display, and/or according to the aspect ratio of the picture contained in the high definition multiplexed analog signal so that the selected group is the one that provides picture information which fits the aspect ratio  of the display.  A timing unit (417) responds to the code (220) so that the selected samples for one scan line are first stored during the active scan line time and then read out sequentially during the sub-sequent scan line time.  The stored samples of each component signal are read out sequentially during substantially the same time period to provide the required Y, U, V signals. A similarly designed demultiplexer may be used to process an extended aspect ratio frequency multiplexed signal such as a high definition NTSC-formatted signal.

Abstract: CORROSION RESISTANT VACUUM BRAZING SHEET                ABSTRACT OF THE DISCLOSURE           A novel process for producing aluminum compo-site sheet products for roll forming and vacuum brazing is disclosed, which provides an unexpected improvement in the corrosion resistance of the brazed product.   According to the process, a composite sheet is annealed to a strain-free state after having been rolled to a thickness which is a critical amount greater than the thickness ultimately sought.  Following the annealing step, the sheet is cold worked to the desired thickness, the degree of reduction in this final step being within a critical range which provides the improvement in cor-rosion resistance to the final product after vacuum brazing.

Abstract: ABSTRACT      This invention describes a reagent system, including saponin in a lysing reagent and a rapidly active cross-linking agent such as glutaraldehyde as a fixing reagent, which reproducably affects whole blood to cause  the red blood cells to stromatolyze and modifies the leukocytes to generate data to define four distinct clusters for detection and classification by flow analysis instrumentation.  The clusters represent the four major leukocyte types found in blood: lymphocytes, monocytes, neutrophils and eosinophils, thus providing a method of leukocyte differential analysis.  The parameters used for the leukocyte classification include combinations of two or more of DC (Coulter) volume, high frequency (RF) size, opacity (RF size/DC volume), light scatter at various angular ranges, and fluorescence at various wavelengths of illumination.
