Abstract: 1. Four-way stop slide valve, more particularly but not exclusively intended to control the diversion of a liquid such as water circulating in a main circuit towards a secondary circuit (10), comprising : - on the one hand one body (1), along which four connection ports (2, 3, 4, 5) with definite widths (D2, D3, D4 and D5) and definite distances between themselves (La, Lb and Lc) are spaced out. The two intermediate ports (2, 3), called "central ports", are intended to be connected one (2) to the inlet of the main circuit liquid (6), the other (3) to the outlet of the liquid towards the continuation of the main circuit, whereas the two extreme ports (4, 5) are intended to be connected to the secondary circuit (10), the one (4) contiguous to the inlet (2) of the main circuit being connected to the outlet (8) towards the secondary circuit, whereas the one (5) contiguous to the outlet port (3) towards the continuation of the main circuit is connected to the return of the aforesaid secondary circuit (10) ; - on the other hand one slide (12) axially sliding in the body (1) and made of one control rod (15), on which two valves (16, 17) are locked with such a definite space (Ld) that, when the slide has been pushed on one side, these valves (16, 17) are situated in the body (1) respectively between, on the one hand, one of the two central ports (2, 3) and, on the other hand, one of the extreme ports (4, 5), whereas, where the slide has been pushed on the other side, position it achieves after one (17) of the valves has passed over a port (2) leading to the main circuit and the other (16) has passed over a port (5) leading to the secondary circuit, in order that one (17) of these valves should place itself between the two central ports (2, 3), while the other valve (16) moves beyond the four ports and becomes inoperative, this valve being characterized in the fact that : - on the one hand, the distance (La ) measured between the center lines of the return (9) port (5) of the secondary circuit (10) and the outlet port (3) towards the continuation of the main circuit is higher than the distance (Lc) measured between the center lines of the outlet (8) port (4) towards the secondary circuit (10) and the inlet port (2) of the main circuit, and, - on the other hand, the distance (Ld) between the center lines of the two valve (16, 17) gaskets is both higher than the sum of the distance (La) measured between the center lines of the return (9) port (5) of the secondary circuit and the outlet (3) port towards the main circuit, increased by the half of the widths (D3, D5) of the same ports, and also lower than the sum (La plus Lb) of the distances measured the first one (La) between the return port (5) of the secondary circuit (10) and the outlet port (3) towards the main circuit and the second one (Lb) between the inlet and outlet ports (2, 3) of the main circuit.

Abstract: The hook lock is particularly adapted for sliding gates where it may be fixed on the surface or within the gate itself. 
<??>The lock comprises an electromagnetic solenoid (19) with related magnetic shell (17), a cylinder lock (38) with key, a device in the form of a hook (4) and a system of five rocker levers (13, 16, 23, 26, 33) activated by a spring compressed plunger (3), said elements arranged in a rectangular metal box (1). 
<??>The whole is assembled in such a way that every time the solenoid (19) receives an electrical impulse, the magnetic shell (17) is attracted and releases the system of rocker levers (13, 16, 23, 26, 33). The combined action of the latter automatically releases and raises the hook (4); the inverse blocking action occurs automatically when the gate closes. 
<??>The lock is mechanically opened manually by using the appropriate key.

Abstract: The present invention relates to latices of sulfonated thermoplastic polymers which function as viscosification agents when added to oil-based drilling muds which are the fluids used to maintain pressure, cool drill bits and lift cuttings from the holes in the drilling operation for oil and gas wells. The sulfonated thermoplastic polymer of the latex has 5 to 100 meq. of sulfonate groups per 100 grams of the sulfonated thermoplastic polymer, wherein the sulfonated groups may be neutralised with a metallic cation or an amine or ammonium counterion. A polar cosolvent can optionally be added to the mixture of oil drilling mud and sulfonated polymer, wherein the polar cosolvent increases the solubility of the sulfonated polymer in the oil drilling mud by decreasing the strong ionic interactions between the sulfonate groups of the sulfonated polymer.
