Abstract: A solid propellant rocket motor or gas generator of the type having retractable filaments (18) embedded in the propellant (13) for the purpose of controlling the overall thrust or mass flow output is combined with a channeled separator (14) located between the propellant (13) and its casing (10) with the channels (16) open to the combustion chamber via ports (17). This results in distribution of combustion chamber pressure and temperatures over the exterior of the propellant grain (13) so that distortion of the grain will not occur sufficiently to cause binding or sticking of the filaments (18) in their holes in the propellant nor will the holes be enlarged to cause uncontrolled burning between the filament and the hole.

Abstract: The transducer comprises an armature and a core. Both pieces are E-shaped, and their geometrical dimensions are chosen so that when their central legs come into mutual contact, air gaps still exist between both pairs of outer legs where these face each other. A coil bobbin is fixed to the core and forms a straight guide for the central leg of the armature. The frontal surfaces of the outer legs are chamfered so that the limiting surfaces of the air gaps are inclined with respect to the travel direction of the armature. In order to minimize the hum, a short-circuit ring is embedded into the central leg of the core.

Abstract: Synchronous demodulation using a lock in amplifier technique improves substantially the signal to noise ratio in a conveyor belt rip detector (11). The lock in amplifier technique uses an analog multiplier to form a product of a received AC transmitter signal, i.e. that received by the rip detector receiver (Re) from an antenna (10) carried by the conveyor belt (3), and an AC reference signal, which has the same frequency as the transmitted AC transmitter signal, i.e. that transmitted by the rip detector transmitter (Tr). A shift in the phase of the AC transmitter signal as it is coupled from the transmitter (Tr) to the receiver (Re) requires a corresponding shift in the phase of the AC reference signal so that the latter is tuned to the same phase as that of the received AC transmitter signal. 
     The invention lends itself to computer control and self- diagnosis of faults of the overall rip detector system. To effect such fault detection not only is there produced an AC transmitter signal and an AC reference signal, but there also is produced a test signal representative of proper operation of the transmitter, and this parameter is checked to learn whether a rip has occurred causing an antenna not to be sensed at an expected location on the belt (3) or a fault has occurred in the rip detector equipment (11).

Abstract: In the design of electrical switchboards or control panels or the like there are employed push buttons for the actuation of a switch for performing a desired control function or operation. There is disclosed a push button containing a solid or rigid front impact flange member and a rear impact cam or detent which is arranged at the tip of a tongue-like spring member or resilient tongue and possesses an inclined guide surface. The push button can be mounted in the cover plate of an assembled switchboard or control panel or the like, without the need for any auxiliary tools, and is positively self-retained thereat without there being required access to the rear side of the cover plate or to the interior of the switchboard panel. A spring-biased support member of a switch arranged rearwardly of the cover plate presses the push button at its near impact surface against the rear side or face of the cover plate and retains such in the desired rest position. The push button can be again dismantled, with the aid of extraordinarily simple means, out of a completely assembled together unit without there being necessitated any access to the rear side of the cover plate.

Abstract: It is desirable in a digital subtraction angiography to realize the stereoscopic X-ray image visualization of a blood vessel by means of an X-ray diagnostic apparatus, In accordance with the invention, the object (2) such as blood vessels is projected by X-rays before and after injection of the X-ray contrast medium at two different projection angles with respect to the object, i.e., right view and left view. So right-viewed X-ray "mask images'" and "subtraction images'" video signals (Ir, IIr) and left-viewed X-ray "mask images'" and "subtraction images'" video signals (II, III) are separatedly obtained. Then the right-viewed mask image's video signal is combined with the left-viewed one, resulting in one stereoscopic visual TV picture consisting of the desired portions of both the right-viewed image and the left-viewed image on the TV monitor (15,16) simultaneously. Similar combination processing is carried out in the subtraction images' video signals, so that one can observe stereoscopically the combined subtraction images of the blood vessels on the TV monitor (15, 16).
