Title: Ultrasonic emergency call system
Inventor: LECLERC LOUIS
IPC: H04B11/00
Filed: 1992-08-21
Abstract: ABSTRACT          An ultrasonic emergency call  anti-agression system designed to indicate in which exact  room a person requiring urgent help is located within a building.          An  ultrasonic  receiver  is  installed in  each  room  under surveillance.  A  miniature  portable  ultrasonic  transmitter  is distributed to personnel required to work in high risk areas. The miniature transmitter is equipped with a switch which, when activated, automatically transmits ultrasonic signals for a 20 second period. The signal activates only the receiver installed within the  room where  the  person  is  located.  Because  of  the transmission characteristics of the ultrasonic frequencies, the receivers  installed in adjacent  rooms are not  activated.  Each receiver is connected via a two pair cable to a control center equipped with an alarm board. Upon reception of an exact ultrasonic frequency signal tasting for a minimum of one second the receiver relay is activated and the room corresponding light is turned on at the alarm board. The system can also be interfaced with an automatic numeric/alphanumeric display  radio paging system for prompt intervention.        After every activation the transmitter emits for 20 seconds to ensure that the receiver is triggered even if the person is being molested or the transmitter has been snatched away from her during an agression.

Inventor: PANARELLA EMILIO
IPC: F24J3/00
Filed: 1994-05-26
Abstract: A process and apparatus are described for generating nuclear effects in a medium which is subject to an inwardly directed spherical compression wave. A centrally located plasma is generated by an ionizing current struck between a pair of electrodes and allowed to begin expansion. A shock wave is generated at a peripheral spherical surface centered on the plasma location. The shock wave encounters the expanding plasma which is then subject to inwardly directed pinch. By timing of the plasma generation and the shock wave generation the plasma can be heated by the pinch effect to temperatures and confinement pressures necessary for x or nuclear radiation or fusion of the medium nuclei as the case may be. Repetitive generation of x-radiation can be obtained from the plasma even in the absence of the pinch shock wave. Significant total doses from such repetition are achieved. When the energizing frequency of the plasma producing current is raised, the radiation pulses overlap and there is continuous output of radiation. Amplification of the repetitive radiation pulse from the plasma can be obtained by timing successive shock wave generation so that such successive waves encounter the plasma at times which enhance its radiation output.

Abstract: ABSTRACT OF THE DISCLOSURE Birds, especially, pigeons dislike the presence of a magnetic field because each bird has a biological instinctive ability of sensing the presence of the magnetic field.  In order to utilize this biological instinctive sensing ability for the purpose of preventing birds from crowding at the upper part of a building, a plurality of magnetic members are disposed on an arm(s) turnably held at the uppermost end of a support column.  When a bird perches on the arm, the latter is turned by the action of his own dead weight, resulting in the bird amazingly flying away from the arm.  It is effective that a rotary wind blade having two magnetic members immovably secured to the opposite sides thereof is disposed at the uppermost end of each support column so as to largely affect the magnetic field induced by the magnetic members disposed on the arm and the magnetic members disposed on the rotary wind blade,  Magnetic members may be disposed on a wire-shaped member tightly spanned between adjacent support columns, a bird threatening unit, a plurality of wires suspending from the upper end of an opening portion located above the veranda of a building or a similar member.

Filed: 1994-08-18
Abstract: AN IMPROVED OPTICAL COUPLING ARRANGEMENT BETWEEN A LAMP AND A LIGHT GUIDE                 ABSTRACT OF THE DISCLOSURE        A central lighting system for providing light to locations remote form the light source includes first and second ellipsoidally shaped reflector members joined so as to substantially surround the light source.  The reflector members collect the light output and focus it onto an input face of either a light guide or a non-imaging optical coupling member.  If the optical coupling member is utilized, an angle to area conversion occurs so as to allow light introduced at high angles to an input face of the optical coupler to exit the optical coupler at a smaller angle.  The reflector members can also be configured so that respective second optical focal points can reside at the apex of the opposing reflector member thereby allowing for a coupling efficiency of approximately 70% or greater.

Title: Batch recirculating system for highly viscous and semi-fluid lubricants
Inventor: BARRETT CHARLES D JR
IPC: F16N29/02
Filed: 1994-12-29
Abstract: A lubricating recirculation system for use with highly viscous lubricants and semi-fluid lubricants such as high viscosity base oil gels and greases.          The system includes a bulk lubricant container for storing fresh lubricant that is applied to the use points  of  the  mechanisms  as  controlled  by  a controller such as programmable logic controller.          After application to the mechanism components, the lubricant falls therefrom and accumulates on guards or channels which help to funnel the lubricant into a spent lubricant holding tank.  Sensors in both the bulk lubricant container and the spent lubricant holding tank,  in connection with the controller, monitor the level of lubricant in both tanks and activate a transfer pump when the level of lubricant in  either  tank  reaches  a  certain  level.  Upon activation of the transfer pump, the spent lubricant is drawn from the spent lubricant holding tank and forced  through  a  filtering  device  to  remove impurities and is then conveyed back to the bulk lubricant container for reapplication to the use points.
