Abstract: n a method of avoiding a drill string becoming stuck during drilling of a well over depth intervals where such equipment has become stuck in similar wells in a geological province, a multiplicity of well drilling variable quantities are measured substantially simultaneously at a known depth in each of a multiplicity of wells. Such multiplicity of wells includes those in which drilling equipment has stuck due to mechanical problems or differential pressure between the drill string and an earth formation penetrated by the well bore, or both, and a multiplicity of similar wells where the drill string did not stick. By multivariate statistical analysis of all variables in all wells of each class, together with maximum separation of said classes from each other, a plotting plane for a currently drilling well relative to said classes is established. The location of the relative position of all variables in such a drilling well with respect to the well classes is determined by summing the products of the coefficient of each variable for the complete group of wells times the current value of the variables in the drilling well. The variables are then modified within allowable values to change the plotted location of the drilling well toward the mean of the wells that did not cause the drill string to stick.

Abstract: A hydrokinetic amplifier 10 having a primary liquid input formed into a primary liquid jet surrounded by a motivating vapor that transfers vapor momentum to the primary liquid jet and accelerates the primary liquid jet through a minimum cross-sectional area 20 upstream of a diffuser is provided with a secondary inlet that admits a secondary fluid to merge with the primary liquid jet in a diffuser 16 beyond the minimum cross-sectional area. Without varying the primary inflows of liquid and vapor, the secondary flow varies inversely with the fluid flow resistance of the output load; and this can be used to vary the volume, pressure, and temperature of the output. The product of the pressure and volume of the combined flows can exceed the product of the pressure and volume of the primary flow, and change in the load resistance can be used to turn the secondary flow on and off for adding a material to the primary flow.

Abstract: A clutch (10) contains two pressure plates (12, 14) which have teeth (26, 32) on mutually facing end faces, via which teeth they engage with one another. As soon as the one pressure plate (12, 14) carries out a tangential movement with respect to the other pressure plate (14, 12), the teeth (26, 32) come to rest on one another and form an axial force which leads to engagement of the clutch (10). A stop (18) is provided on one of the two pressure plates (12, 14), which stop permits a limited, an unlimited or even no relative movement between the two pressure plates (12, 14). The stop (18) is controlled as a function of parameters such as the steering angle and the direction of travel. Two such clutches (10) are used in a differential of a wheel drive.

Abstract: A method for locating a mobile station, and a mobile radio telephone station and a fixed base station for carrying out the method. Identity signals and a precise time pulse are transmitted from fixed radio telephone stations (S1-S5) of known locations. The transmission takes place either as a response to an interrogation transmitted from the mobile station or automatically at predetermined intervals. All of the fixed stations are in highly precise chronological synchronization, and the transmission time of a precise time pulse may be only a specific one, for example, occur­ring at 1-second intervals. As this interval is great com­pared with the travel time of the time pulse, it is possi­ble, by eliminating any multiples of the fixed time inter­val, on the basis of the arrival time of the time pulses received at the mobile station, to calculate at any given time the distance difference between two fixed stations and, with the aid of at least three fixed stations, the location of the mobile station. All that the method re­quires is supplementation of an existing radio telephone network, and the signals concerning the localization can be transmitted, for example, on the auxiliary carrier waves of the system.
