Title: Structural-shape steel rolling mill and method of operating same
Inventor: ENGEL GEORG
IPC: B21B1/14
Filed: 1987-08-14
Granted: 1992-08-11
Abstract: ABSTRACT OF THE DISCLOSURE         The structural steel rolling mill comprises a reversing two high rough rolling mill, at least one universal working rolling mill and at least one flanging edging rolling mill included in a reversing tandem rolling mill group, and a universal finishing rolling mill at the outlet end of the structural steel rolling mill.  Without substantial lowering of the throughput of the mill considerable savings of both space and operating expenses are attained.  These savings are attained because the reversing tandem group following the rough rolling mill has a universal working rolling mill, a flanging edging rolling mill and the universal finishing rolling mill.  By including the universal finishing rolling mill in the reversing tandem rolling mill group the uni-versal finishing rolling mill also participates in the reversing action and because of that is more effective in shaping than the standard finishing rolling mill so that in practice the special universal finishing rolling mill following the reversing tandem group is omitted as well as the edging rolling mill commonly pro-vided with it and the roller bed located between them.  The dimensional accuracy and the surface properties of the rolled pro-duct as well as the service life of the rolls of the universal finishing rolling mill are not impaired when the reduction of the universal finishing rolling mill is set smaller than that of the universal working rolling mill.

Title: Nondestructive readout of a latent electrostatic image formed on an insulating material
Inventor: KAMIENIECKI EMIL
IPC: G01R29/14
Filed: 1988-05-04
Granted: 1992-02-11
Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus are described for the nondestructive readout of a latent electrostatic image formed on a sheet or layer of insulating material.  A sheet or layer of semiconductor material is disposed in relatively close proximity to the  insulating material.  A latent electrostatic image formed on the insulating material (by any known means) causes a surface depletion layer to be produced by induction at the surface of the semiconductor material.  The location and distribution of the accumulated charges on the semiconductor material are read out as analog electrical signals corresponding to the AC surface photovoltage induced on the semiconductor material as the semiconductor material is scanned with a low intensity modulated light beam of appropriate wavelength, the magnitude of the analog signals depending on the local charge density.  The analog electrical signals so obtained are then digitized, processed and stored and/or displayed.

Title: Short-wire bed-of-nails test fixture
Inventor: IERARDI JOSEPH A
IPC: G01R1/073
Filed: 1988-08-04
Granted: 1992-02-04
Abstract: ABSTRACT OF THE DISCLOSURE        A test fixture for automatic testing equipment wherein a short wire interface assembly permits the interface assembly to be hard wired to a test head assembly with relatively short interconnect  wires.   The  interface  assembly  includes  a  base cover plate having a plurality of cavities  formed therein,  a plurality of individual interface strips having flexible vacuum seals   affixed   thereto   and   interface   contacts   disposed therethrough,  and  a  plurality  of  floating  captive  contacts disposed in the base cover plate to provide a mechanical  and electrical  interface  between  the  interface  contacts  and spring-loaded probes electrically connected to  the ATE.   The individual interface strips  are readily positionable adjacent the test head assembly to facilitate hard wiring therebetween.          Further,  the  individual  interface  strips  are  rotatable  to provide easy access to the interface contacts for hard wiring.          The  hard wired  interface  strips  are  suspended in respective cavities of the base cover plate with the flexible vacuum seals in contact with a surface of the base cover plate.  During ATE testing a vacuum pressure is applied to the other surface of the  base  cover  plate  and  the  high  initial  loading  of  the spring-loaded probes is exerted against  the  floating  captive contacts.   Limiting  the  translation  of  the  floating  captive contacts   correspondingly   limits   the   deflection   of   the individual interface  strips.   The  flexible  vacuum  seals  are designed to be load-insensitive, that is, the deflection of the interface  strips  causes  a  limited  flexure  in  the  flexible vacuum seals which is insufficient to disrupt the atmospheric pressure induced sealing contact between the outer edges of the flexible vacuum seals and the base cover plate.
