Granted: 1992-09-22
Abstract: RADIO TELEPHONE APPARATUS          ABSTRACT OF THE DISCLOSURE       Radio telephone apparatus for use in a cellular mobile tele-phone system comprises means for alarming at least a user operating the apparatus in response to a drop in signal strength of radio fre-quency signals received over an established communication channel when the apparatus approaches a boundary of service area in a cellu-lar mobile telephone system. The signal strength is repetitively checked to determine if it has fallen below a first predetermined sig-nal strength value. When the signal strength falls to or below a sec-ond predetermined signal strength value, the radio telephone appara-tus causes a disconnection of the telephone link and returns the appa-ratus to a standby mode.

Granted: 1993-01-12
Abstract: Sheath for use in the drying of skins.            ABSTRACT      The sheath for use in the drying of skins or furs (1)  is designed as an elongated bag and is pro-duced  from  a  fat  absorbing  air-permeable  material having a certain natural  resiliency,  e.g.  non-woven fibres of polypropylene.     This provides for obtaining that the sheath (3) contrary to prior sheaths is now capable of covering the  total  actual  length  of  the  board  (2),  thereby obtaining an improved protection of the board against getting smudged by remains from the inside of the skin (1). Moreover, a more homogeneous air dispersion during the drying process is obtained and thereby also a more uniform drying of the skins.

Abstract: Abstract of the Disclosure Repair of transparent errors in masks utilized for lithographic processes in the manufacture of devices is accomplished by a particularly expedient procedure. In this procedure a metal ion beam such as a gallium ion beam is directed to the region that is to be repaired. An organic gas, including a material having an aromatic ring with an unsaturated substituent, is introduced into this region. The interaction of the gas with the ion beam produces an opaque adherent deposit. The resolution for this deposition is extremely good and is suitable for extremely fine design rules, e.g., 1 µm and below.

Granted: 1992-08-25
Abstract: SURGICAL STAPLER SAFETY AND SEQUENCING MECHANISMS            Abstract of the Disclosure:     A surgical stapling instrument is provided having safety and sequencing features to mandate proper operation of the instrument during surgical clamping and stapling of tissue.  The instrument is powered by pressurized gas, and includes a manual control for supplying gas to a clamping mechanism in the stapler head and a trigger for actuating a stapling mechanism therein.  The instrument prevents actuation of the trigger until the tissue has been clamped.  The trigger may not be actuated to implant staples until a trigger safety has been actuated. Following actuation of the stapling mechanism, the instrument is either automatically reset to its initial condition, or may require manual control by the user to restore the clamping and stapling mechanisms to their initial conditions.  The instrument affords correct sequencing of operation and prevents inadvertent stapling.

Abstract: A new dot enzyme immunoassay (EIA) with a conserved portion of the envelope protein of the human immunodeficiency virus (HIV) as antigen has been designed for use in areas with few laboratory facilities and by personnel with little laboratory experience. Sera were tested in 263 subjects who had AIDS or AIDS-related complex or were at -risk or not-at-risk of AIDS from the USA, Africa, and Asia/Oceania.  The dot EIA was 100% sensitive in the American subjects, and there were only 2 false negatives in the others, both of which were negative by commercial EIA.  The test is simple to perform, economical, rapid (30 min), and stable.

Accessing the row corresponding to a particular object returns a description of all of the attributes of the object's  component  objects,  as  well  as  information describing the object itself.   The packed description information is redundantly stored conventionally in other system  catalogs  for  use  IN  at  IN  querying  physical definitions of objects in a manner consistent with other database  products.   The  database  state  information comprising  the  packed  descriptions  is  retained  in internal  format  whereas  the  correlative  redundant information is in a user-readable external format.  By denormalizing  the  schema  for  schema  data  whereby identifying relationships between objects is simplified, time required for compilation of statements referencing objects  is  substantially,   reduced.  All  information concerning attributes of an object specified in statement and  its  component  objects  necessary,  to  compile  the statement  may  thereby  be  fetched  from  the  packed description field corresponding to the object in one I/O operation.   Objects  descriptions  must  otherwise  be retrieved from numerous I/Os to separate system catalogs and rows collectively containing the descriptions.

The tag includes a frequency-dividing transponder including an active strip of magnetic material that when magnetically biased to be within a predetermined magnetic field intensity range responds to excitation by electromagnetic radiation of a first predetermined frequency by radiating electromagnetic radiation of a second predetermined frequency that is a frequency-divided quotient of the first predetermined frequency; a first bias strip of magnetic material disposed in relation to the active strip of magnetic material for biasing the active strip of magnetic material to be within the predeterminedmagnetic field intensity range only when the first bias strip of magnetic material is magnetized; and a second bias strip of magnetic material disposed in relation tothe active strip of magnetic material for further biasing the active strip to beoutside of the predetermined magnetic field intensity range to thereby prevent the active strip of magnetic material from radiating electromagnetic radiation of the second predetermined frequency in response to excitation by electromagnetic radiation of the first predetermined frequency when the first and second bias strips of magnetic material are both magnetized. A coded tag includes two such active strips having different magnetomechanical resonant frequencies. Either tag may be detected In a presence detection system that includes means for transmitting an electromagnetic radiation signal of a first predetermined frequency into a surveillance zone; and means for detecting electromagnetic radiation of the second predetermined frequency within the surveillance zone.

Abstract: Resonant tubes of a pulse combustor are immersed in a bed of solid particles in a reaction zone to provide indirect heat from the pulsating combustion gases to the solid particles of the bed.  The bed is maintained in an agitated state by a gas or vapor flowing through the bed.  Reactant materials are introduced into the agitated bed and undergo reaction at enhanced rates resulting from heat transfer coefficients at least about twice as high as those of steady flow combustors and an intense acoustic pressure level propagated from the pulsating combustor into the reaction zone.  The apparatus is useful, for example, to steam reform heavy hydrocarbons and to gasify carbonaceous material, including biomass and black liquor to produce combustible gas at relatively low temperatures, with steam being utilized as the bed fluidizing medium.  Black liquor gasification, utilizing sodium carbonate as bed solids, results in liquor energy and chemical content recovery without smelt production.
