Patent EP-0148618-A3 (EP)
IPC: H04N11/08
Filed: 1984-12-18
Abstract: A method and system for reconstruction of chroma com­
ponent segments in a line sequential chroma format television 
system. Filtering of a received line sequential chroma signal is 
employed to reconstruct missing chroma components and to 
attenuate phantom frequency components greater than one 
half the spatial sampling rate. Digital and analog filters are dis­
closed for implementation of such post filtering. The luminance 
component of the line sequential signal is delayed at the trans­
mitter to synchronize the reconstructed chroma segment with 
its corresponding luminance segment with the use of minimal 
hardware at the receiver. Horizontal offset chroma sampling is 
used along with such post filtering to decrease transmission 
bandwidth requirements without sacrificing horizontal resolu­
tion at the receiver.
Patent EP-0168643-A3 (EP)
Title: Device for the inspection of wafers
IPC: G01N21/88
Filed: 1985-06-14
Abstract: This invention enables examination of semi-conductor chips either on a planar basis or on a three-dimensional basis to determine the characteristics of the chips. Laser light is passed through a first pinhole and is focussed on a wafer. The light reflected from the wafer is passed through a second pinhole and is focussed on a photomultiplier. The focal length between the first pinhole and the wafer is the same as the focal length between the second pinhole and the multiplier. This arrangement provides for a high signal-to-noise ratio to be produced and image information data to be provided within minimal time lags such as a small fraction of a second. An electrically controllable active mirror operable within the beam-shaping optics of the scanning field may be included to displace the plane of the examination field. This active mirror may be controlled to assume the shape of different types of mirrors including a planar mirror. By controlling the operation of the active mirror, the etchings of first materials on the wafer and the depositions of other materials on the wafer may be examined at different depths. The control of the active mirror may be provided at a different frequency than the frequency of the light providing for the examination of the wafer. The visual portion of the light spectrum from the laser may be further processed to determine such parameters in the wafer as the distribution of photoresist residues on the wafer.

Patent EP-0154520-A3 (EP)
IPC: E21B31/20
Filed: 1985-02-28
Abstract: A releasable spear for retrieving tubular members from 
a well bore has a top member (1) connencted to a mandrel (2) 
which in turn is connected to a lower member (3), the remote 
end of the member (3) from the mandrel (2) being adapted to 
secure a cutter (not shown). Rotatably and longitudinally 
slidably disposed about the mandrel (2) is a sleeve (4) having 
a tapered portion (45) which is arranged to mate with and 
slidably cooperate with a corresponding taper (51) on the 
inside diameter of a grapple carrier (5) having grapples (50). 
In a non-expanded position of the grapples (50) the grapple 
carrier (5) is located on wedges (7) but upon rotation of the 
sleeve (4) by a dog clutch (60, 61) so the wedges (7) locate 
within a longitudinal keyway (8) of the grapple carrier and 
the grapple carrier (5) slides downwardly over the keys 
thereby radially expanding the grapples. By increasing the 
tension on the drilling string so the radially outward pressure 
of the grapples (50) upon the internal surfaces of the tubular 
member to be machined is increased. Whilst maintaining the 
drilling string in tension fluid is pumped through internal 
passages (10, 22, 36) of the members (1, 3) and mandrel (2) to 
radially extend the cutter and the spear may then be rotated 
to sever the tubular member whilst the drilling string is in 
tension.  
     In another embodiment, instead of grapples an external 
screw thread (401) is provided on a sleeve (400) to suit a 
thread on the well head to be cut. In a further embodiment, 
again instead of using grapples a two part sleeve (421, 422) is 
provided with a cam (440) and radially expandable pins (430) 
which are driven outwardly by rotation of the cam to engage 
with the internal surface of a tubular member to be cut.

Patent EP-0162722-A3 (EP)
IPC: A46B3/18
Filed: 1985-05-23
Abstract: The invention concerns an applicator for pasty, liquid or 
semi-liquid cosmetics materials such as mascara. Known ap­
plicators, in which an elongate applicator member formed 
integrally with a closure for a contained of the material, may 
comprise a twisted wire brush carried at the end of a support 
shaft, have the disadvantage that the geometry of the brush 
is fixed. Thus a brush ideal for one type of application will 
be generally unsuitable for another. Other known applicators 
having fine end bristles suffer the problem that the bristles 
become damaged upon insertion through a narrow wiper 
opening of the material container. The arrangement of the 
invention avoids these problems by providing a cover (4) for 
the material retaining part (3) of the elongate member, rel­
ative movement between this cover and elongate member 
being permitted to provide selective and/or adjustable cov­
ering of the material retaining part. Thus the amount of this 
part (3) which is exposed for use can be varied. The config­
uration of the exposed part may also change.

Abstract: A multiple solution IV administration system 
(10) includes a plurality of IV fluid sources which 
are connected by flexible tubing (30,40,22) to the 
inlet of an IV pump (12). A sequence valve (18) 
suspended from the tubing (22,24) selectively pinches 
off all but one tube so that one source at a time is 
connected to the inlet. The sequence valve (18) is 
controlled as a function of the accumulated volume 
pumped by the pump (12) for each fluid and a stored 
volume limit for that fluid. When the accumulated 
volume of one IV fluid reaches its volume limit, the 
sequence valve (18) is changed to connect a different 
source to the inlet of the IV pump (12). The desired 
volume limits and rates are entered manually and are 
checked automatically to protect against setup errors.

Title: Pressure barrier liner, method of construction thereof and method of testing for leakage
IPC: E02D31/00
Filed: 1987-06-16
Abstract: A pressure barrier liner (38) has a plurality of low permeability membranes (42, 44) disposed one above the other. A region of relatively high permeability is encapsulated between each adjacent pair of membranes. Pressurizing means may be used to introduce (58) pressurized fluid such as air or water into a selected group of the high permeability regions (46) to pressurize them to a selected pressure or pressures, thereby ensuring that any flow through the membranes (42, 44) or through disruptions in the membranes will be from within the pressurized regions to the regions outside the membranes (42, 44) which encapsulate the pressurized regions, rather than from the fluid storage region above the membranes, through the membranes and into the region beneath the membranes which is to be protected by the liner. Alternatively, depressurizing means may be used to depressurize a selected group of the high permeability regions to a selected pressure or pressures thereby ensuring that any fluid flow through disruptions in the membranes (42, 44) is directed to and withdrawn by the depressurizing means, thus again preventing fluid escapement from the fluid containment region above the membranes, through the membranes and into the region beneath the membranes which is to be protected by the liner.

Title: Low melting urethane linked toluenediisocyanates
IPC: C07C269/02
Filed: 1987-07-01
Abstract: This invention relates to urethane linked mixtures of 2,4-and 2,6- toluenediisocyanates (ULTDI dimers) having low melting points and to a method of forming these systems. The urethane linked toluenediisocyanates containing from 45-90% of the 2,4-and 10-55% of the 2,6- isomer by weight are formed by reacting two moles of an appropriate isomer mix of toluenediisocyanate, with one mole of a specific alkylene glycol, e.g., 1,2-butanediol, diethylene glycol or dipropylene glycol under conditions such that essentially only one of the isocyanate groups on a toluenediisocyanate molecule reacts with a hydroxyl group of the glycol. Conditions are controlled such that the urethane linked toluenediisocyanates are formed. The resulting product, which has two unreacted isocyanate groups, is suited for producing a variety of elastomers including polyurethane polyurethane/urea or polyurea elastomers.

Patent EP-0275472-A3 (EP)
Title: Method for removing impurities from waste gas
IPC: B01D53/00
Filed: 1987-12-12
Abstract: The removal of impurities from exhaust gases takes place by cooling the exhaust gas by means of a circulation gas and condensing out of the impurities in two groups of reversible heat exchangers. Each group consists of two precoolers and one low temperature cooler. While the impurities condense out in one group, they are thawed in the other group. In order to simplify the control, only one precooler is used in each group, which is charged with two inside gases, namely, the exhaust gas and the circulation gas. Only two simple control systems which can be easily program-controlled are then required for the purification process. In addition, the temperature increase of the circulation gas in the circulation gas blower can be utilized for heating up purposes in the group to be thawed.
