Abstract: A binding (5) for a snow shoe (1) includes a front binding portion (9). The front binding portion (9) includes a base plate (11) from which a pair of side walls (9a, 9b) extend upward. The side walls have upward extensions (13a, 13b) which have transverse slots (14) defined therein. Upper wall portions or straps (10a, 10b) have detents (16) which are slidably received in the slots. A heel engaging loop (21) is connected with cables (18a, 18b) which engage the top wall portions or the detents. As the loop is pulled over the heel of the boots, the cables pull the detents downward through the slots, drawing the side walls together, contracting a cavity (15) which they define tightly around the toe of the boot.

Abstract: A snow shoe (1) has a peripheral frame (2) which defines an interior zone. A central part (14) is disposed centrally in the open zone to receive a binding (5). A plurality of support walls (40) extend transversely between the central part and the peripheral frame. The support walls are downwardly concave, having a central portion (40c) disposed between front portions (40a) and rear portions (40b). Forward downward extending edges (42a) extend downward from the front wall portion and rearward downward extending edges (42b) extend downward from the rear wall portions.

Abstract: Snow-shoe consisting of a boot retaining device of the type including a retainer device in front (9) in which is retained the front extremity of said boot, which is there acted upon by at least one pulling device toward the front (11) characterized in that the front retainer device is an elastic envelope made up by a set of walls (15a, 15b, 15c, 15d) of pliable material forming a retainer cavity open toward the rear, characterized in that the retainer cavity consists of two lateral retainer walls (15b, 15c) converging toward the front, and the convergence of which and their distance from each other is such that the front extremity of the boot is maintained laterally by these walls at two lateral points separated from each other.

Abstract: Snowshoe (1) consisting of a perforated plate formed by a peripheral frame (2) including a vertical wall (3) and a screen (4) supporting the attachment designed to hold the user's shoe, the central part (20) being extended toward the front by a front part (21) and toward the rear by a back part (22), wherein at least one of the lateral rims of the frame (2) and/or the screen (4) is concave in the central part (20).

Abstract: In accordance with the present invention, there are provided novel assays which allow the identification of compounds which block the ability of lentiviruses to infect non-dividing cells. Compounds discovered employing the invention methods can be employed to block the ability of HIV to infect non-dividing cells. In accordance with another aspect of the present invention, novel antibodies have been developed which are specifically immunoreactive with the phosphorylated form of HIV-1 MA. In accordance with yet another aspect of the present invention, novel kinases which phosphorylate HIV-1 MA have been discovered.

Abstract: A multiplier for two binary values, X and Y, comprising a very high number (q) of bits, wherein memories storing the numbers X and Y and a result register MR are provided, X being expressed as the sequence of bits (x.sub.q-1 . . . x.sub.j . . . x.sub.0), uses the algorithm consisting in sequentially carrying out from j=q-1 to j=0 the additions 2R+x.sub.j Y and each time entering the result in the result memory (MR). In this multiplier the adders are grouped into n blocks of m bits (with n.times.m=q), m being chosen so that the carry transfer time into a block is lower than a clock period. Each block comprises a first and a second line of elementary adders forming the cells (C.sub.1 to C.sub.m+1) associated with each pair of bits to be added. This multiplier is more particularly adapted for carrying out the operations XYmodN and X.sup.S modN.
