Patent DE-2966039-D1 (DE)
Title: Retractable gripper device for gripping hollow bodies within the mouth thereof
Inventor: MAUPATE JACQUES
IPC: B65B21/12
Filed: 1979-12-21
Granted: 1983-09-08
Abstract: Apparatus is described for grasping hollow bodies, such as bottles, from the inside. It is particularly useful in protecting grasping equipment used in conjunction with bottle coating equipment. On a movable rod inside a housing are mounted a structure adapted to engage the rim of the bottle and grasping arms which can be inserted into the neck of the bottle. The rod is spring-biased toward a position in which the structure and the grasping arms are retained within the housing. To grasp a bottle, a force is applied to the rod against this spring-bias so as to urge the rod, the structure and the grasping arms toward the bottle. At an intermediate point on the outward stroke, the structure is released from the rod. If the structure engages the rim of the bottle after its release and before the outward stroke ends, the structure is prevented by a slider from moving back into the housing and relative movement between the rod and the structure causes the grasping arms to engage the inside of the bottle. If, however, no bottle is present, the structure is resecured to the rod toward the end of its outward stroke and on the return stroke of the rod the structure is returned to within the housing. As a result, the grasping arms and rim engaging structure do not remain outside the housing and are not coated with the coating when a bottle is not present.

Title: Spectral shift controlled nuclear reactor
Inventor: CARLSON WILLIAM RALPH
IPC: G21C7/32
Filed: 1981-12-04
Granted: 1984-12-13
Abstract: A spectral shift pressurized water reactor comprising apparatus (38) for inserting and withdrawing water displacer elements (40, 82) having differing neutron absorbing capabilities for selectively changing the watermoderator volume in the core (34) thereby changing the reactivity of the core. The displacer elements (40, 82) comprise substantially hollow cylindrical low neutron absorbing rods (40) and substantially hollow cylindrical- thick walled stainless rods (82). Since the stainless steel displacer rods have greater neutron absorbing capability, they can effect greater reactivity change per rod. However, by arranging fewer stainless steel displacer rods (82) in a cluster, the reactivity worth of the stainless steel displacer rod cluster can be less than a low neutron absorbing displacer rod cluster.

Date Feb. 12, 1987.A method of identifying and detecting remote objects by transmitting wave energy and receiving wave energy reflected from the object. Separate signal parameters pertaining to the wave energy received are processed forming a measured signature of the object. The measured signature is compared with a number of prestored signatures having the same signal parameters relating to known objects of interest. A recording is made of which prestored signatures correspond to the measured signature within predetermined tolerances. Subsequent transmission and reception of wave energy is used for updating the separate parameters and the measured signature. The updated measured signature is compared with the recorded prestored signatures for updated recording of a smaller number of prestored signatures corresponding to the updated measured signature within the predetermined tolerances.

Abstract: A coupling sleeve (3) pushed onto the plastic pipe (1) and provided with barbs (3a) is drawn over a driving shoulder against the connecting piece (2) by a union nut (4). The opened-out pipe end (1a) is clamped between a curved end face of the connecting piece (2) and the coupling sleeve (3). Possible leakages caused by the flow of the pipe material are prevented by a spring (6), and the pipe (1) is prevented from turning during assembly by a sliding ring (5). The device used for assembling the pipe connection has grips (13) for fixing the pipe in position with a toggle lock (16) and a press ring (26), which can be displaced in sliding manner on a stop (25) acting as a centering arbor, and can be actuated by a hand lever (31). With only a few manipulations, the coupling sleeve (3) can be pushed onto the centrally held plastic pipe (1). Owing to the omission of the supporting sleeve required hitherto, the through-flow cross-section of the plastic pipe (1) is not reduced by the installation of this pipe connection. Heating up the end of the plastic pipe is no longer necessary during assembly. The pipe connection, which can be made cost effectively, is uncomplicated in its construction and absolutely liquid-tight.
