Abstract: The system allows to control the operation of one or more apparatus or plants, each one having at least a telephone set coupled to the telephone system. 
     The system comprises:
     one or more peripheral control units, each one coupled to a relevant apparatus or plant to be controlled, and coupled to one or more electrical sensors, in turn coupled to the controlled apparatus or plant, each one of the sensors providing at its output electrical data signals indicative of controlled parameters, and which may be coupled to the telephone line  ;  connected to a the telephone set located in the same building where the apparatus or plant to be controlled is located;   a central control unit, which may be coupled to the telephone line, and apt to send signals to and receive signals from each peripheral control unit.   Each peripheral control unit includes switching means coupled to the telephone set and to the telephone line and apt to:
   a) ascertain whether by means of said telephone line calling pulses are received at least during two subsequent time periods (T,, T 2 ) starting from the start of the first calling pulse received;   b) decouple for a predetermined period of time starting from the start of the first calling pulse the telephone set from the telephone line;   c) in the case that during the second of said time periods T 2  no calling pulses are received, decouple said telephone set from the line and allow that the signals from the peripheral control unit are sent in the line, and   d) restore the initial situation of wiring between said telephone line, said telephone set and said peripheral unit when the transmission of information between peripheral and central unit by means of the telephone line is over.

Abstract: In the case of a spindle nut (108) with its ball return means for a ball screw, the return channels are in each case designed in separate inserts which are inserted in a cut-out formed on the inner side of the spindle nut (108). In one exemplary embodiment of the invention, the cut-outs are designed as somewhat trough-shaped depressions, parallel to the spindle nut axis and passing through the spindle nut (108) preferably over its entire length, the return inserts having a cross-sectional shape corresponding to this depression. This depression can be produced in a very simple manner by a drilling and rotating operation. In another exemplary embodiment, a return insert (66, 72) is arranged at the outlet end and at the inlet end of a ball channel, the return insert being designed as a stopper passing radially through the spindle nut wall (50). The transfer channel sections (78, 80) are formed on the radially inner side of this stopper. The stoppers are seated in holes (82, 84) passing radially through the spindle nut wall. <IMAGE>

Abstract: A centralizer for well casing (16) functions in an annular space between the casing (16) and a wellbore (20). It comprises a pair of axially spaced-apart and aligned collars (12) adapted to encircle the well casing and a plurality of spring bows (14) extending between and secured to the collars. Each spring bow (14, 280) has two ends and an outwardly convex curved mid-portion. In a first form of the invention starting force is reduced by providing spring bows having outwardly projecting contact angle reduction members (282) that engage the upper edge of the wellbore (20) as the casing (16) is moved into the wellbore (20) to reduce the effective contact angle of the spring bows (14, 280) with respect to the wellbore (20) and thereby reduce the force required to insert the centralizer (10) into the wellbore (20). In a second form of the invention the spring bows are provided with casing abutment members (283) extending inwardly towards the centralizer's longitudinal axis. The casing abutment members (283) contact the casing (16) as the spring bows (14, 280) are moved towards the casing (16) during insertion of the centralizer (10) into the wellbore (20) to increase the restoring force of the spring bows. The spring bows may have both contact angle reduction members (282) and casing abutment members (283) to give a centralizer having a desirable combination of low starting force with high restoring force.

Abstract: A latch (53′) on the window frame moves between a locked position, in which it engages a strike on the swingable seal and holds the sash in the closed position, and an unlocked position, in which it releases the strike and frees the sash for movement away from the closed position. A reversible rotary actuator (41′) mounted on the frame, is rotated in a first direction to first move the latch (53′) from the locked position to the unlocked position and to then move the sash away from the closed position, and it rotated in a second direction to first move the sash the closed position and then to move the latch (53′) toward the locked position at about the same time as the sash reaches the closed position. Two nuts (104,105) move along a screw (101) rotated by the actuator (41′). A first linkage (115-117) connected between the sash and the first nut (104) is operable to move the sash towards and away from the closed position when first nut (104) is moved in opposite direction along the screw (101). A second linkage (72′,77′) connected between the latch (53′) and the second nut (105) is operable to move the latch (53′) toward and away from the locked position when the second nut (105) is moved in opposite directions along the screw (101). When the sash is closed and the latch (53′) is locked, movement of the first nut (104) along the screw (101) is delayed until the screw has been rotated sufficiently far to advance the second nut (105) along the screw a predetermined distance. When the sahd is closed and the latch (53′) is unlocked, movement of the first nut (104) along the screw (101) in the said   closing direction is prevented during rotation of the screw while permitting the second nut (105) to move along the screw in the latch-locking direction.
