Abstract: ABSTRACT OF THE DISCLOSURE:          A device for detecting the flowing of a fluid in a pipe, comprising a tubular element vertically mounted on the pipe for serially interconnecting two portions of this pipe.  One of these portions is connected to the upper end of the tubular element while the other portion is connected to its lower end.  A piston made of a magnetic material is slidably mounted within the tubular element and is there-fore free to move along it.  A by pass conduit interconnects a part of the tubular element adjacent to its lower end with the portion of the pipe which is connected to the upper end of the tubular element to allow the fluid to flow from the portion of the pipe connected at the lower end of the tubular element to the portion of the pipe connected at its upper end.  In operation, the piston moves upwardly in the tubular element as soon as the fluid starts to flow to allow this fluid to flow from the portion of the pipe connected at the lower end of the tubular element to the one connected at its upper end through the by-pass conduit.  The piston moves downwardly by gravity to the lower end of the tubular element as soon as the fluid stops flowing.  A coil wound around a portion of the tubular element produces an electrical signal every time the piston moves in the tubular element. This detecting device can be mounted on a hot water supply pipe and used in combination with an electronic circuit for saving energy in operating a hot water system comprising a tank for stocking hot water, an apparatus for heating the water within the tank, and a thermostat for controlling the operation of the water heating apparatus in accordance with the temperature of the water in the tank.  In this case, the electronic circuit allows or prevents the thermostat to control the water heating apparatus.

Abstract: ABSTRACT     A screening apparatus includes a conveyor (10) pivotally mounted at its rear end on a wheeled chassis (2). The conveyor (10) includes a rear section (12) and a forward section (14) telescopically connected to the rear section (12).  An endless belt (16) is guided and powered by spaced rollers (18) mounted on the conveyor rear and forward sections (12) and (14).  The conveyor (10) is moved between its operational and transporting positions by a jacking cylinder (20).  A screen device (30) is pivotally coupled to the output stage of the forward section (14), and is controlled by a ram (36).  A hopper (8) for receiving the material to be separated is mounted on the chassis (2).  To convert the apparatus from its operational position to its transporting position, the jacking cylinder (20) lowers the conveyor (10), two sets of troughing rollers (38) are removed from the forward section (14), and the ram (36) is disconnected from the forward section (14).     This forward section (14) is partially telescoped into the rear section (12), and the screen device (30) is pivoted clockwise and bolted to the rear section (12).

Abstract: A FIRE SIMULATION DEVICE FOR         TRAINING IN THE OPERATION OF         SHOULDER WEAPONS AND THE LIKE            Abstract of the Disclosure The simulation device provides training in the firing of rockets or guided missiles by means of a shoulder weapon.  As soon as a shot is fired, the firer's field of view is occulted by a shutter.  The aim at the instant of firing and the point of impact with respect to the target are displayed on an instructor's video screen.  The target can be of a fictitious type generated by a computer and produced within the field of view of both the instructor and the firer at the same time.  In the case of a real target, an index can be controlled by the instructor in order to locate the target and follow its progress up to the instant of firing.  The result of the firing operation is judged according to the position of the point of impact with respect to the fictitious target or with respect to the index.  The choice of the mode of operation is made on a control desk.

Abstract: ABSTRACT            A "passive interrogator label system"  (PILS)  comprises an interrogator for transmitting an interrogation signal, one or more "labels" or passive transponders which produce a reply signal containing coded information in response to the interrogation signal, and a receiver and decoder for receiving the reply signal and decoding the information contained in it.  The frequency of the interrogation signal assumes a plurality of frequency values within a prescribed frequency range.  The decoder includes a mixer (4 quadrant multiplexer)  for  mixing  together  the  interrogation  and reply signals  (or signals derived therefrom) to produce a further signal containing frequencies which are the sum and difference  of  the  interrogation  and  reply  signals.   A signal processor,  responsive to this further signal pro-duced by the mixer,  detects at least some of the  fre-quencies contained in this further signal and determines the informational code associated with the transponder.
