Title: Method of spatially thresholding a discrete color image
Inventor: STELZENMULLER WILLIAM K
IPC: H04N1/41
Filed: 1986-03-27
Granted: 1992-04-28
Abstract: Abstract A method is disclosed for thresholding the luminance component of color picture elements (pels) prior to compression.  The method is most effective when use dwith discrete color images, such as documents having areas of nominally constant color.  The method uses spatial information rather than histogram information to threshold the image data.  Each scan line is defined as having a series of pel runs.  A pel is considered to be in a run if it's luminance is within a certain range of an average luminance based on preceding pels.  Each run may end in a transition region wherein the luminance of each pel differs from the luminance of the preceding pel by more than a predetermined amount.  Where a transition region is found, a local threshold is set based on the average luminance of the preceding run and of the following pel.  All pels in the transition region are assigned a luminance value equal either to the average luminance of the preceding run or the actual luminance of the following pel.

Abstract: ABSTRACT OF THE DISCLOSURE     The disclosure relates to a projectile which is intended for penetration into targets of both slight and great resistance to pen-etration. The projectile is also operative for exploding the payload of the projectile after penetration. The projectile includes a for-ward barrier of high strength material and a fuse adapted to be de-tonated on impact with targets of each respective type. This fuse operates with high sensitivity on impact with targets of slight re-sistance to penetration and by delayed action which permits  ex-plosion of the payload (39) of the projectile after penetration. A delayed action charge (44) included in the fuse is placed behind the barrier (5) and is allocated a protected position where shock waves which occur in the forward material portions of the projectile are prevented from triggering or actuating the delayed action charge. The delayed action charge is exposed to a unit (31) placed between the barrier (5) and the delayed action charge, the unit, when the fuse is detonated, effectuating a reliable ignition of the delayed action charge.

Title: Apparatus for producing separable fastener member
Inventor: FISCHER JAMES R
IPC: B29L5/00
Filed: 1986-06-11
Granted: 1990-10-09
Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus for continuously producing an elongated strip-like fastener member is disclosed which facilitates highly efficient of resiliently flexible hook-like projections. The method comprises the formation of an extrusion of plastic material which is shaped between a pair of coacting first and second rollers of the apparatus. Notably, one of the rollers is formed of a series of plates and defines a plurality of hook-forming cavities about its periphery within which the hook projections of the fastener member are formed. The forming roller is suitably cooled so as to effect substantial reduction in the temperature of the molten plastic extrusion form which the fastener member is formed. In this manner, the fastener member may be removed or stripped from the forming roller without opening of the hook-forming cavities, thus promoting highly efficient formation of the fastener member without resort to unduly complex equipment or processes. The fastener is uniquely configured and includes upstanding hook-like engaging elements having stem portions of at least partially arcuate configuration to produce a combination of properties previously unknown in such fasteners.

Title: Floating negative automatic grounding switch

Filed: 1986-10-01
Granted: 1992-09-22
Abstract: FLOATING NEGATIVE AUTOMATIC GROUNDING SWITCH          ABSTRACT OF THE DISCLOSURE:          In  certain  DC  powered systems,  particularly   traction  power systems such as electrified railways, it is becoming the practise to  isolate both the positive and negative busses  -- from  which the  system load derives its power -- from ground.  However,  the rolling stock (streetcars or train cars) maintains the chassis of the car at the potential of the negative bus;  and  under certain conditions its potential may float away from ground potential, to the  extent  that  any person standing at  ground  potential  and touching the chassis might receive an electric shock. The present invention   provides  a  circuit  having  sensing   means   which determines  whether the potential of the negative bus relative to ground  has exceeded a predetermined  limit,  either  positive  or negative with respect to ground, or whether the rate of change of potential  of  the negative bus with respect to ground exceeds  a predetermined rate;  and in either event,  the sensing means acts to  cause  a  switch means which  is  usually  a  normally  open silicon  controlled rectifier arranged to face in the appropriate direction,  to close and thereby to cause a short circuit between the  negative bus and ground.  The switch is retained  in  closed condition  until  the current through it reduces to substantially zero. In certain circumstances, it may be that it is the positive bus which is monitored.  In any event, the circuit acts to ground the monitored bus under abnormal conditions,  rather than to lift the  monitored  bus away from ground potential as  would  be  the usual case.

Abstract: METHODS AND COMPOSITIONS             USING LIPOSOME-ENCAPSULTED NON-STEROIDAL                        ANTI-INFLAMMATORY DRUGS     ABSTRACT     Methods and compositions are described for the treatment of inflammatory diseases including the use of liposomes to deliver nonsteroidal anti-inflammatory drugs.  Drugs may be encapsulated in the liposomes during their preparation, or alternatively, are combined with the liposomes following their formation.  The composition may include glycolipids such as galactolipids including digalactosyl diglyceride, and the liposomes may be made by a number of procedures and rendered free of exogenous nonsteroidal anti-inflammatory drugs.  The compositions may be administered to mammals including humans.

Title: Ladder support for eavestrough or gutter
Inventor: MORIN FERNAND R
IPC: E06C7/48
Filed: 1987-07-16
Granted: 1991-01-08
Abstract: A B S T R A C T    A ladder support is provided for use with an eavestrough or gutter.  The support is mounted in the eavestrough without the necessity of using fasteners.  It is also mostly concealed by the eavestrough and yet supports the ladder in spaced rela-tionship thereto so that the ladder does not contact the eavestrough and cause damage to it.  The ladder support in-cludes two main legs having members at first ends adapted to engage the eavestrough at the juncture of a back wall and a bottom thereof with the legs being of  sufficient length to extend above and beyond a front rim of the eavestrough.  Sec-ond ends of the main legs have brackets for engaging the rails of the ladder to support it spaced from the eavestrough and to resist sideways movement.  Outwardly-extending leg braces are affixed to intermediate portions of the main legs and have feet for engaging the interior of the rim for resisting movement of the main legs when a ladder is supported thereby.
