Abstract: An improved Bernoulli end effector for holding, handling, and transporting ultra-thin substrates includes edge guides to aid in the positioning of the substrate and may include friction pads that impede motion of the substrate lifted by the end effector. The Bernoulli end effector may be incorporated into an apparatus and method for supinating a substrate so that both surfaces of the substrate can be processed. In addition, the Bernoulli end effector may be used to place ultra-thin substrates on and retrieve substrates from a substrate handling structure that includes weights that prevent the substrates from bowing or flexing during processing and includes guides that prevent the ultra-thin substrates from moving or translating on the surface of the substrate handling structure.

Abstract: In a unilateral NMR probe for the analysis of a material comprising at least one magnet for generating a constant time-invariant polarization field B0 in the material to be analyzed and current conductors forming a radio frequency oscillation circuit for generating a pulsed radio frequency magnetic excitation field B1 which is superimposed on the polarization field N0 in the material, the circuit conductors are so designed as to provide several adjacent excitation fields B0 with alternatingly oppositely oriented magnetic fields, whereby the current conductors generating each one of the excitation fields have a distance from each other which causes a certain penetration depth in the material to be analyzed and echoes received therefrom provide measurement values which are characteristic for the material being analyzed.

Abstract: The invention relates to a detector for detecting electrically neutral particles. The detector has a housing (10) filled with a counting gas. A converter (22) in the housing (10) generates conversion products as a result of the absorption of the neutral particles. The conversion products generate electrically charged particles in the counting gas, and a readout device (19) detects the electrically charged particles. A device (18) generates an electrical drift field for the electrically charged particles in a region of the volume of the counting gas so that at least some of the electrically charged particles drift toward the readout device (19). The converter device (22) is of charge-transparent design and being arranged in the detector housing (10) so that the drift field passes through at least part of this device.

Abstract: In a process and apparatus for producing elongate curved hollow bodies at least partially comprising thermoplastic material a preform is extruded from an extrusion system head and engaged by a gripping means. The preform is moved by the gripping means into the region of a guide stencil disposed above the mold cavity of a mold portion of a divided blow molding mold and introduced into the mold cavity by a simultaneous downward movement of the gripping means and a movement following the configuration of the guide stencil. The guide stencil has two mutually opposite walls, the spacing of which increases in an upward direction and the spacing of which at the bottom of the guide stencil approximately corresponds to the maximum width of the mold cavity. The preform is thus guided towards the mold cavity by the walls, acquiring its definitive orientation with respect thereto by virtue of such guidance, passing through a lower opening in the guide stencil into the mold cavity.

Abstract: The subject invention relates to electrode structures that are adaptable for primary and electrically rechargeable electrochemical wafer cells. A flat wafer cell is disclosed that includes conductive, carbon-filled polymeric outer layers that serve as electrode contacts and as a means of containment of the cell. Multi-cell, higher voltage batteries may be constructed by stacking individual cells. Specially formulated electrodes and processing techniques that are compatible with the wafer cell construction are disclosed for a nickel-metal hydride battery system. This invention is further directed to fabrication of electrodes from electrochemically active material prepared by coating non- to low-conductive particles of a metal hydroxide or metal oxide powder with nickel using a electroless nickel coating process. The cell design and electrode formulations provide for individual operation of a vented or low pressure sealed cell and/or for operation of these cells in a stacked array in an outer battery housing.

Abstract: A casing for holding a key in one of two pivoted positions. The key pivots about an axis extending along one edge thereof when a lock is turned by the user of the key. An indicator may be attached to the key for extension through a small opening in the casing or housing when the key is in one position and for retraction below the level of the casing periphery when the key is in the opposite position. In a second embodiment, a portion of the casing may be pierced along three edges and arranged so that, when the key is in one position, the pierced portion is pushed above the casing periphery and, when the key is pivoted to the second position, the pierced portion is coextensive with or below the casing periphery. In a third embodiment, an indicator may be pivotally fastened in position between halves of the casing for movement (a) above and (b) even with or below the periphery of the casing when the key is pivoted.

Abstract: The output of an auxiliary sensor, such as a magnetometer or metal detector, is recorded along side a sonar trace record, such as from a side scan sonar or sonar sub-bottom profiler, using the same recorder mechanism. In one embodiment, the added information permits correlation on the same chart between sonar generated impressions and local magnetic field disturbances such as produced by magnetically susceptible objects located on or below the seabed. The sonar record is typically provided as a series of adjacent scan lines, intensity modulated in accordance with the intensity of a received sonar echo. A conversion circuit transforms the output of the auxiliary sensor into a format consistent with the sonar scan trace whereby the sensor output is directly reproduced as a part of the sonar trace record, typically at a peripheral edge portion where the sonar image is absent.
