Abstract: ABSTRACT OF THE DISCLOSURE   Apparatus for determining the rotor angle of a synchronous machine relative to a fixed axis is disclosed.  A field position sensor measures the voltage induced in the stator with the stator winding current off when the rotor winding current is turned on, and provides a rotating magnetic flux vector angular position to set an integrator to a starting value for rotor angle position.  Thereafter the integrator integrates the rotary speed signal fed from a tachometer.  A function former responds to the integrator sum of the initial rotor angle and the integrated rotary speed signal to provide a rotor angle signal for control of the machine.  The disclosed apparatus provides simple, relatively inexpensive rotary angle measurement.

Abstract: ABSTRACT OF THE DISCLOSURE     A water faucet is disclosed that is automatically turned on and off in response to the proximity of the user's hand or other object to the faucet.  An ultrasonic transducer is located in the faucet near the water outlet and transmits bursts of ultrasonic waves. When a wave reflects off a user's hand and creates an echo signal, the echo is detected by the ultrasonic transducer.  Circuitry connected to the ultrasonic transducer determines when an object is within a predetermined distance of the faucet by measuring the time elapsed between the transmission of the burst and the recep-tion of the echo.  Once an object is within this predetermined distance, the circuitry causes a valve to open and water is supplied by the faucet.

Abstract: SINGLE AND MULTIPLE SECTION PIPE REPAIR           OR SERVICE CLAMPS                       ABSTRACT          A low profile pipe clamp for use in encircling a pipe such as a main or the like, the clamp being either a repair clamp or a service clamp with a side outlet.  The pipe clamp comprises a flexible band, usually of sheet metal with a gasket material on the interior thereof and having at least a pair of opposed looped ends which receive tubular or hollow trunnion loading bars.  One of the trunnion loading bars is provided with an aperture therethrough for receiving a T-bolt, whereas the other trunnion bar is provided with a slot having a widened portion capable of receiving the T-head of the T-bolt.  By use of the trunnion loading bars, the load created during drawing together of the looped ends by the T-bolt and nut assembly is uniformly spread across the width of the looped ends and this permits higher torques to be utilized when tightening the nut on the T-bolt and higher clamping loads may be applied by the band to the pipe.  The T-bolt is preassembled in the trunnion bar having the aperture therethrough with the nut being applied to the T-bolt and then the T-head of the T-bolt may be flipped or pivoted into the other trunnion loading bar through the enlarged portion of the slot in the other trunnion loading bar. The trunnion loading bar having the slot therein is temporarily held in a predetermined position prior to installation of the clamp so as to make for easier control in flipping the T-head of the T-bolt into position within the slot.  On large clamps where more than one T-bolt and nut assembly is provided in spaced parallel realtionship across the width of the clamp the trunnion loading bar which initially retains the T-bolt is made into a plurality of coaxial elements so that each of the T-bolts may be independently pivoted into position during assembly.

Abstract: ABSTRACT       Amphibian vehicle for shallow water, adapted for executing ground operations, such as dredging, removal of growth in channels, ditches and water courses. The vehicle has a hull (1) with floating capacity, comprising a pontoon under which several mechanisms for adjusting the height can be mounted, such as vertically slidable posts (32) or pivot-able two armed levers (8). These rest in their turn on ground transport mechanisms, such as drums (7), track assemblies (30;31) or such.        The invention places the mechanisms (8;32) for adjust-ing the height and the bottom transport mechanisms outwardly from the hull (1) and therefore freely movable with respect to the hull. This gives an improved stability during the operations standing on the bottom (4) and also during sailing, whereby the possible applications are enlarged. As the vehicle is self propelled also the displacement speed can be substan-tially increased.          Fig. 1.

Abstract: ABSTRACT      A suspension system for an overhead contact wire for electric traction vehicles has a carrier cable with its mid point connected to a support and having each of its ends connected to respective clamps.  The clamps comprise a jaw assembly including a generally cylindrical housing fitted with inwardly directed teeth on its inside surface, the housing receiving an angularly adjustable link member which includes an angle-determining portion provided with comple-mentary teeth and interfitting with the teeth of the housing. The link member may be moved axially into and out from the toothed housing so that it may be set in different angular positions therein, thereby changing the location of a point fastened to the end of the carrier cable relative to the contact wire.  The carrier cable tends to pull the link member against an axial abutment, thus locking it in a selected angular position,and by suitably selecting the angular position, the contact wire may be suspended vertically below the clamping means in order to avoid interfering with vehicle pantographs, even where the contact wire is following a curved path thereby causing the plane defined by the carrier cable and the contact wire to be sloping at an angle from the vertical.
