Abstract: Abstract A continuous water flow from selected ones of a plurality of reservoirs passes through turbines or the like within an hydroelectric power station to produce electrical power.  The reservoirs are cyclically filled and evacuated through the power station by operation of a plurality of gates interconnecting reservoirs having different water height levels and an adjacent source of tidal waters.  By programmed operation of the gates a continuous water pressure head can be maintained at the power station to assure continuous electrical power generation.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention relates to a method for regulating the phase position of a controlled signal in relation to the phase position of a reference signal in a telecommunication system and an arrangement for carrying out the method.  The reference sig-nal is delayed in a delay circuit and the delayed reference sig-nal is compared with a controlled signal in a first comparison circuit which produces a first comparison signal at a high or a low level in dependence on the phase difference between the de-layed reference signal and the controlled signal.  The controlled signal is delayed in a delay circuit and the delayed controlled signal is compared in a second comparison circuit with the refer-ence signal.  The second comparison circuit produces a second comparison signal which is at a high or a low level in dependence on the phase difference between the signal and the reference sig-nal.   The outputs from the comparison circuits are connected to a logic circuit. In dependence on the signal combination received at its inputs the logic circuit produces a binary control signal which is used to correct the phase position of the controlled signal in relation to the phase position of the reference signal.

Abstract: THIN FILM INDUCTIVE TRANSDUCER                      Abstract This thin film inductive transducer comprises a yoke structure consisting of a pole tip region which joins a back region.  To maximize resolution during reading of magnetic transitions from a moving magnetic recording medium, the pole tip region is of preselected constant relatively narrow width, and composed of magnetic layers having edges which extend in a direction normal to the medium for a distance D from an air bearing surface ABS to the back region and having a small thickness at least adjacent the ABS.  To minimize the effects of spurious signals from adjacent tracks on the medium, distance D is at least 5/d, where d is the recording density on the medium; however, to maximize transducer efficiency, distance n is not increased significantly above 5/d.  To oppose saturation of the yoke structure with applied current and enhance the efficiency of the transducer during recording, the cross-sectional area of the yoke structure is increased in the back region by progressively increasing its width rearward of the pole tip region and concurrently increasing the thickness of said magnetic layers at least about 60%.

Abstract: Abstract Of The Disclosure The engine of a mobile power crane-excavator is utilized as a source of heat to soften grease so that it may be applied to the open gears on the machine, even at low ambient temperatures. Heated water from the vehicle engine is caused to flow in heat transfer relationship with cold grease through a multi-conductor hose to provide a pre-heat of the grease.  The heated water is caused to heat a metallic nozzle through which the pre-heated grease flows, thus creating a final heating of the grease up to the desired temperature. Air supplied through the nozzle causes the grease to be sprayed onto the gear.  The remote supply tank for the grease may also be pre-heated with hot water from the vehicle engine.

Abstract: ABSTRACT OF THE DISCLOSURE     A wok having a bowl-shaped configuration including a relatively shallow curving bottom portion and curving sides which increase in slope upwardly is described.  The wok differs from customary woks in that the exterior sur-face of the bottom portion is flat so that the thickness of the bottom portion increases from the center generally radially outwardly and this thickened material forms a heat sink.  The flat exterior bottom permits the wok to be seated on electrical heating surfaces for maximum heat transfer.  The wok is also provided with a handle construc-tion which includes a pair of oppositely directed handles integrally formed with the bowl-like utensil portion and extending outwardly and terminating in grip members formed of insulating material.

Abstract: ABSTRACT In producing a polyacetal homopolymer or copolymer a liquid starting mixture containing molten trioxane and a catalyst and optionally a comonomer is continuously fed through a feed opening of a reactor.  The reactor is a continuously stirring-type mixer comprising a hollow barrel having the feed opening for the starting materials spaced-apart from discharge opening for the reaction product.  The barrel has a cross-sectional surface corresponding to two overlapping eccentric circles having the same diameter.  A jacket is pro-vided on the periphery of the barrel for temperature control.  Stirring shafts disposed within the hollow barrel parallel to each other extend longitudinally of the barrel through the central parts of the circles.  The stirring shafts having a plurality of plate-like paddles fixed thereto in such a manner that the paddles fixed to one stirring shaft are kept in contact with each other.  The cross-section of each of the paddles taken perpendicularly of the axial direction of the stirring shaft has the shape of a convex lens, an ellipse or a quasipoly-gon inscribing a phantom circle at each vertex.  One of the paddles and another facing paddle fixed to the other stirring shaft are positioned such that the one rotates while the edges thereof keep a slight clearance from the inner surface of the barrel and the other paddle.  The starting mixture is polymerized while being moved towards the discharge opening by the rotation of the paddles.  The reaction product is withdrawn in the form of a finely divided solid from the discharge opening.  The improvement lies in that the profiles of the paddles are charged or the arrangement of the paddles is changed continuously or step-wise, so that the transportability of the reaction mixture becomes progressively smaller from the feed opening toward the discharge opening of the reactor.  On the same stirring shaft, the paddles are arranged such that with respect to one paddle, a paddle adjacent thereto on the discharge opening side of the reactor deviates by an angle of less than 180° in the direction opposite to the rotating direction of the stirring shaft.
