Abstract: AN IMPROVED POWER TAKE-OFF LEVER ARRANGEMENT FOR A TRACTOR       Abstract of the Disclosure An improved power take-off lever arrangement for a tractor is disclosed which prevents the inadvertent shifting of the PTO lever from a first to a second position.  The lever arrangement includes a support plate secured to the tractor and has a pin extending outward therefrom which engages an oval aperture formed in a manually operated lever.  The lever is connected to a control valve for hydraulically engaging a power take-off drive.  The control valve is responsive to move to a second position with corresponding movement of the lever and is spring biased to move to a first position with corresponding movement of the lever when the hydraulic pressure falls below a predetermined value.  The lever is also spring biased to the first position such that an attachment mechanism formed on both the lever and the pin engages.  The improvement includes a keyway formed in the periphery of the pin which is aligned with and engages the keyway when the lever is in the first position and is out of alignment with the keyway but is in contact with the periphery of the pin when the lever is in the second position.

Abstract: PATENT                  ETUDES ET FABRICATIONS FLOPETROL                  PIEZOELECTRIC TRANSDUCER, NOTABLY FOR PRESSURE MEASUREMENT                      ABSTRACT OF THE DISCLOSURE    In a pressure transducer of the piezoelectric type, a resonator (10) is made up of a pellet (16) mounted inside an element designed to be subjected to the action of a pressure on its exterior face (18).  The pellet  (16)  and the  element  (12)  are  cut  in the same quartz block, using a cut which provides two vibration modes. The forces resulting from the external pressure are transmitted to the edge of the pellet (16) by connecting bridges (22, 23) whose orien-tation is  chosen so that  one  of the vibration modes has maximum sensitivity to the forces while the  other mode has a practically zero sensitivity.

Abstract: Méthode de fabrication de cette dalle par coulée de béton dans un moule ou l'on a introduit une armature. Selon la méthode on se munit d'abord de moules rectangulaires dont au moins deux côtés opposés sont évasés. On coule ensuite du béton dans un moule tout en y introduisant l'armature et l'on poursuit cette opération jusqu'à ce que le moule soit complètement rempli. D'autre part, on prépare des poutrelles d'acier munies de patins d'assise à chacune de leurs extrémités, chacune des poutrelles étant formée d'une base et d'une tête reliée à la base par un système de tiges métalliques en zigzag. On place ensuite les deux poutrelles parallèles entre elles ainsi qu'avec les deux côtés évasés et à distance l'une de l'autre, au-dessus de la surface du béton fraîchement coulé dans le moule et on y fait pénétrer la tête à l'aide de deux tire-forts d'acier en forme de U jusqu'à ce que les patins d'assise des poutrelles affleurent la surface du béton. On laisse ensuite prendre le béton dans lequel la tête des poutrelles est encastrée. On démoule ensuite la dalle de béton armé, de préférence en la saisissant par les poutrelles et on lui fait alors subir une rotation de 180.degree. selon son axe longitudinal de façon à ce qu'elle soit prête à être disposée sur une charpente pour constituer une dalle de plancher.

Abstract: Abstract of the Disclosure A chopper has a housing centered on an axis and having a radially open input and a radially open output spaced angularly therefrom as well as a pair of axially oppositely open intakes, and a cutter drum rotatable in the housing about the axis and having a pair of end plates transverse of the axis and having axially oppositely directed faces confronting the respective intakes and a plurality of blades secured to and between the end plates and having cutting edges defining on rotation of the drum an orbit centered on the axis;  Respective pluralities of vanes at the end plates can be secured either to the respective end plates in in-service positions extending generally radially thereon so that rotation of the drum moves the vanes to draw air in the axial intakes and expel it through the radial output or in an out-of-service position in which they do not move appreciable air.  The vanes can be secured in the out-of-service position also to the respective end plates but extending generally only angularly.  In particular the vanes form a radially closed cylindrical annulus in the out-of-service position.  This annulus generally blocks flow from the intake to the output in the out-of-service position.       The vanes can also be secured in the out-of-service position so as not to rotate with the drum.

Abstract: ABSTRACT            A method of reconstructing, at the receiving end, digital data defining an encoded voice signal segment lost in transmission between the transmitter and the receiver in a transmission system wherein a low-frequency signal such as a residual baseband signal is derived at the transmitting end from the signal to be encoded and is then distributed among several sub-bands whose sampled contents are quantized separately. The reconstruction method includes a step of analyzing the received signal to detect any missing segment thereof and, as the case may be, to initiate an analysis, within each sub-band, of the segment(s) adjacent to the lost segment, so as to generate a term relating to the period T(k) of the signal so analyzed and to reconstruct a segment of signal of period T(k) intended to be substituted for the lost segment.

Abstract: PROTEIN ASSAY BY SILVER BINDING                ABSTRACT  OF THE DISCLOSURE           A novel, inexpensive, highly sensitive and quantitative assay for measuring protein in solution based on the capacity of protein to bind silver is des-cribed.  In this procedure, protein samples are first treated with glutaraldehyde and then exposed to ammonia-cal silver.  After a specified time, the reaction is terminated by the addition of sodium thiosulfate and the optical density measured at 420 nm.  The useful range of the assay for the majority of standard proteins tested lies between 15 and 2000 ng.  This represents a 100-fold increase in sensitivity over the coomassie Brilliant Blue dye binding procedure.  There is little or no interference from carbohydrates, non-ionic detergents or ethanol.  Pretreatment of protein samples with Bio-Gel P-2 to remove salts, thiol agents, EDTA and SDS, makes this procedure compatible with most commonly used buf-fers.

Abstract: Method and Apparatus for Adding Electrolyte to a Fuel Cell Stack Abstract Electrolyte is replenished in a fully assembled stack of fuel cells by depositing dilute electrolyte on tabs extending outwardly from an external vertical face of the stack..  The electrolyte is absorbed into the cell components as it cascades off the tabs and down the face of the stack.  When the electrodes and matrix layers of the stack are fully saturated the stack is heated and water is evaporated until the stack has an operable electrolyte volume and electrolyte concentration therein.  In a preferred embodiment the tabs are extensions of the nonporous plates separating adjacent cells in the stack.
