Patent FR-2560295-A1 (FR)
Title: Drilling turbine multi-staged hydraulic turbine
Inventor: BRUDNY-CHELYADINOV SERGEI JULI
IPC: F03B13/02
Filed: 1984-02-24
Abstract: The invention relates to the drilling of wells or the like. The hydraulic turbine which is the subject of the invention is of the type in which the vanes of the turbine blades of at least some of the rings 8, 9 are made so that the angle alpha of curvature of the median line of their profile is greater than the acute angle beta formed between the tangent to this line at the turbine blade outlet 16, 17 and the axis S of driving fluid flow, and is especially characterised in that, in a stage comprising at least one set of turbine blades 16, 17 having the said curvature of the median line of its profile, the ring 8, 9 comprising this set of turbine blades 16, 17 is provided with bypass channels arranged hydraulically in parallel with the flow channel 12, 13 of the ring 8, 9 and putting the space between this ring 8, 9 and the preceding ring 9, 8 in communication with the space formed between this same ring 8, 9 and the following ring 8, 9, so as to bypass part of the driving fluid of the flow channel 12, 13 of the ring 8, 9.

Patent FR-2560409-A1 (FR)
Title: Arithmetic unit for adding parallel bits
IPC: G06F7/60
Filed: 1984-02-28
Abstract: The arithmetic unit (such as 33 and D3) adds 2<N-1> parallel input bits b1 (= A3B1) to b2N-1 (=S21) so as to supply N parallel output bits SN-1 (= S32) to S0 (= S30) of a sum binary word. SN-1 and S0 are the most-significant bits and least-significant bits of the sum word. The unit comprises input means 33 for summing the incoming bits b1 to b2N-1 into a sum current where I0 is a constant, and output means D3 comparing the sum current to at least N intermediate current levels (2<N>-1)I0/2, ... (2<N-n+1>-1)I0/2, ... I0/2 so as to supply the output bits SN-1 to S0. The number of MOS-type transistors included in the unit is smaller than in those according to the prior art, which considerably reduces the installation surface of an integrated circuit using such a unit for comparable speeds of operation. Such an integrated circuit can be a multiplication circuit in which the summing of partial products Aj bk in a column of rank i = j + k - 1 is obtained by an arithmetic unit according to the invention.

Title: Dismantleable and interchangeable racquet with single handle
IPC: A63B49/02
Filed: 1985-12-04
Abstract: Dismantleable racquet, with single handle and interchangeable end. This invention relates to a device offering the possibility of changing a racquet (material, size of the stringing head, different strings) without changing the handle. Thus, problems of "hand gripping", contact and overall size of the racquet no longer exist. There is thus a proximal part "A", comprising a grip 1 and a male assembly piece 2, as well as a ring 4 intended for immobilising the assembly; and a distal part "B", comprising the stringing head and the strings, and a short handle ending in a female assembly piece 3. The whole assembly constituted by the elements "A" and "B" may thus be dismantled or assembled easily and rapidly, rendering the part "B" interchangeable and giving the racquet a small overall size.
