Title: Apparatus and method for selectively forming a thickened edge on a plate of formable material
Inventor: BLUNIER DENNIS L
IPC: B21B1/22
Filed: 1990-05-09
Abstract: Abstract of the Disclosure Apparatus And Method For Selectively Forming A Thickened Edge On A Plate Of Formable Material In conventional fabrication manufacture the thickness of the steel plates are often determined by the metal section required at the weld joints.  The subject apparatus and method overcomes this problem by selectively forming a thickened edge along the edge of a thinner steel plate which can now be limited to the thickness required to withstand the stresses on the fabrication.  The thickened edge is produced by forcing a plate supported by a table, by passing the plate through a forming apparatus comprised of a combination of rollers.  The forming apparatus and table are automatically controlled to produce a thickened edge of constant shape along a non-linear edge of the plate.   t:\srb\88-302us.doc

Abstract: ABSTRACT    A least recently used associative map is described for translating  virtual  memory  addresses  to  real  memory addresses.  The map includes a stack of storage devices each with a comparator.  The storage devices are arranged in a push down stack with an input storage device to receive the incoming virtual address and store the corresponding real address and the other storage devices coupled to the output of the previous higher  storage devices and with storage devices storing the translation of virtual address and real address in order of recent use with the  last or bottom storage  device  storing the  least  recently used  address. When the comparator detects a compare that real address is provided out and that translation is applied to the input storage device as the most recently used translation and the other translations are shifted down the stack to replace in the storage device that had the compare with the translation from the previous storage device.  If there is not a compare a new translation is entered at the input storage device and the  other translations  are  shifted down with the  least recently used being shifted out if the storage devices are full.

Title: Method and apparatus for detecting changes in the liquid level of a storage tank
Inventor: JENSEN JAY E

Filed: 1990-07-19
Abstract: A METHOD AND APPARATUS FOR DETECTING CHANGES IN THE         LIQUID LEVEL OF A STORAGE TANK                        ABSTRACT    An apparatus for detecting a change in the amount of liquid in a storage tank 12 comprises a vertical upright standpipe 14 for filling with a liquid to a level that generates a hydrostatic head pressure substantially equivalent to that exerted by the liquid in the storage tank. A sensor 18 senses the hydrostatic head pressure differential between the liquid in the storage tank 12 and the liquid in the standpipe 14. A horizontally disposed pipe 16 connects the tank 12 to the pressure sensor 18 and a further horizontally disposed pipe 20 connects the pressure sensor 18 to the standpipe 14, with the pipes 16, 20 being in substantial axial alignment with each other.  Any change in the liquid pressure in the tank 12 as a result of leakage from the tank will change the differential pressure measured by the pressure sensor 18.  The apparatus is particularly useful in the detection of leaks from storage tanks containing highly volatile liquids, such as gasoline.

Title: Magnetic antenna system having independently controllable electrical field shielding and magnetic field balance
Inventor: CORDERY ROBERT A
IPC: H01Q7/04
Filed: 1990-08-14
Abstract: A magnetic antenna system particularly useable in electronic article surveillance systems for detecting the presence of a resonant tag utilizes multiple loop shielded transmitting and receiving antennas. The antennas employ shield structures that are designed to minimize the electric field response and to provide a balanced magnetic field response. The magnetic field responses of different ones of the loops in each of the antennas are different and the loops are oriented so that more responsive loops of the transmitting antenna are positioned opposite less responsive loops of the receiving antenna and vice versa in order to reduce the coupling between antennas without reducing the sensitivity of the receiving antenna to a tag signal.
