Abstract: Abstract of the Disclosure The invention is directed to a container for storing radioactive materials such as irradiated nuclear reactor fuel elements and the like.  The vessel of the container is configured to have a plurality of wall layers.  The inner wall layer of the vessel consists of a mechanically stable inexpensive metal material which is surrounded by a corrosion-protective wall layer made of high-alloy austenitic castable material with nodular graphite.  The receiving opening of the vessel is closed by a sealing cover welded to the corrosion-protective layer.  The container serves not only as a container for the final storage, it also can be utilized for a long-term storage at a surface location as well as for transport of the irradiated fuel elements.  The amount of material needed for the corrosion-protective layer is held as low as possible.  This is achieved by casting a wall layer of cast iron containing nodular graphite in surrounding relationship to the corrosion-resistant wall layer.  The thickness of this outer wall layer is selected to afford the required shielding effect.

Abstract: ABSTRACT OF THE DISCLOSURE        An animal trap wherein the housing is formed of sheet metal and the trap door is of a mesh construction wherein the animal can in no way gain access to one carrying the trap or one disposed adjacent to the trap.  At the same time, the animal may be identified through the open-mesh trap door.  The trap door is normally disposed in a recessed position under-lying the vertical wall; and, when released by a control mechanism actuated by a trap pan, the door will automatically fall by gravity to a trap-closing position. The door is then locked in this trap-closing position by means of a latch rod which has a roughened or threaded sur-face which interlocks with a spring clip.  The housing, being formed of sheet metal and being substantially imper-forate, may be utilized for the purpose of destroying the animal either by drowning or grassing.

Abstract: ABSTRACT. IMPROVEMENTS IN OR RELATING TO DECISION CIRCUITS. A decision circuit (20) is responsive to digital input signals (22) and to timing signals (21) for reshaping and retiming the input signals into reshaped and retimed output signals.  The decision circuit also is responsive to the digital input signals and absence of the timing signals for reshaping but not retiming the digital input signals into reshaped output signals which are transmitted.  Thus the circuit produces and transmits reshaped output signals even upon failure to apply the timing signals as required by previous decision circuits.

Abstract: ABSTRACT OF THE DISCLOSURE         INTEGRAL DISK BRAKE ACTUATOR AND ADJUSTER        A brake wear adjuster 30 is mounted within the bore of an actuator piston 20 having a snap ring 46 at the entrance of the bore.  The adjuster 30 includes a spring holder 42 having a uniquely configured washer 52 that is seated in a groove 50 in the outer surface of the holder.  A spring 40 is carried about the holder between the washer 52 and a flange 42c at the opposite end of the holder.  A pin 32 having a mounted swage 36 and a deformable swage tube 38 are carried within the bore of the spring holder 42, the swage tube 38 being movable with the holder 42 while the pin 32 and swage 36 are stationary.  Upon hydraulic fluid pressure being applied to the piston 20, the snap ring 46 engages the washer 52 and it in turn compresses the spring 40 as it moves through the distance established in the groove 50.  An occurrence of disk wear in the brakes causes the piston 20 and holder 42 to move further drawing the swage tube 38 over the swage 360 Upon release of the pressure, the spring 40 moves the washer 52 and snap ring 46 and thus also the piston 20 to a retracted position to disengage the brake disks.

Variations in speed and direction will result in desired combinations of "pitch" and "roll" movements.

Abstract: ABSTRACT OF THE DISCLOSURE          Closed-loop controller for altering the power level of nuclear reactors in a safe manner and without overshoot.  Apparatus is provided for moving a control element such as a control rod or for adjusting the con-centration of a soluble neutron absorber (chemical shim) for altering the nuclear reactor power level.  A computer computes at short time intervals the two functions [p-¦p¦/.lambda.e]/¦p¦ and ?iln(PF/Pi).  The direction of motion of the control element is altered when these two fun-ctions become equal thereby resulting in the attainment of a new power level without overshoot.  In a preferred embodiment, these two functions are computed at intervals of approximately one second.
