Title: Peroxygen breaker systems for well completion fluids
IPC: E21B43/26
Filed: 1986-07-08

Subsequently, the viscosity of the medium decreases to facilitate the removal of the medium.
Patent EP-0232874-A3 (EP)
Title: Configuration of standard colours configuration of standard colours
IPC: G09B23/22
Filed: 1987-02-07
Abstract: In order to overcome difficulties which arise when making conventional color charts and color spaces, a torus-shaped spacial structure is used as base body for the arrangement of color tones. The gray tones are located at the outermost jacket area thereof and the clearest colors are located at the inner jacket area thereof. In the inside of the body, the colors extend through all color tone steps from the clearest up to the gray tones. By means of an iterative method for the arranging of color tones in the torus, it is possible not only to discriminate the color tones for the human eye equidistantly, but also to represent the brown colors reliably.

Patent EP-0256738-A3 (EP)
IPC: A61B3/02
Filed: 1987-08-03
Abstract: An automated visual testing system is disclosed 
which presents an alternating steady state visual stimulus 
to a patient through an optical system that modifies the 
stimulus image. As the image changes, the patient produces 
evoked potentials that change. The evoked potentials are 
detected (14 + 54 - 58) by a product 
detector which produces the amplitude 
of the evoked potentials. A control processor (12) controls a 
stimulus generator (20) to produce the image and an optical 
system transmits the image to the patient (22). A supervisor 
computer (10) produces patient response curves resulting from 
the evoked potential signals; diagnoses malfunctions in the 
patient's vision and prescribes correction.

Abstract: A wheel chair is made up of a wheeled chassis (11) and a seat 
(12) wherein the seat (12) and the chassis (11) are discrete, 
self supporting members and a demountable coupling (26, 27, 46) 
is provided linking the seat (12) to the chassis (11). The 
coupling (26, 27, 46) is operable between a first position 
where the coupling (36, 27, 46) secures the seat (12) to the 
chassis (11) and a second position where the coupling (26, 27, 
46) releases the seat (12) from engagement with the chassis 
(11). A control linkage (39, 29, 37, 32) provides for 
regulating the operation of the coupling (26, 27, 46) at least 
from the first to the second position. A lifting point (44) is 
incorporated in the seat structure (40) to enable at least the 
seat (12) (with or without an occupant) to be lifted alone or

Title: A digital-to-digital code converter
IPC: H03M7/38
Filed: 1988-07-14
Abstract: The present invention relates to a digital-to-digital code converter (10), or 
decimator, which implements sinc³ processing. The input signal (X) to the code 
converter comprises a series of groups, each group including a series of N digital 
sample values occurring at high rate ( 
) which are converted within the 
converter, using sinc³ processing, into a single digital value occurring at, for 
example, a  1 / Nτ rate for delivery to the converter output (Y). The code 
converter comprises three processing stages (11-13) in cascade, where each stage 
includes separate accumulation means (20-22), each accumulation means 
arranged to add, during each series of N input sample values, the signal value 
received by that stage from the next preceding stage. Each of the three stages 
further includes a separate subprocessing means (23-26) for processing the 
resultant accumulated digital value from the associated accumulation means at 
the end of each group period to produce a separate processed digital value 
which, when combined with the processed digital values from the other stages at 
the end of a group period, provides a single sinc³ processed digital value for the 
N input signal samples of each input group.

Title: Particle classifier
IPC: B07B11/04
Filed: 1985-02-07
Abstract: A particle classifier includes a generally cylindrical, air and fine particles permeable cage having a closed top and open bottom mounted to a central drive shaft. A casing surrounds the cage and defines a volute air passage about the cage with an air separation zone between the volute and the cage. A generally tangential air inlet is provided in casing volute and a material inlet is provided in the the upper end of the casing. A stationary chamber is positioned below the cage for the air and fine material which enter the cage. From the chamber, the air and fine material is directed to cyclone separators in which the air is separated from the particles. A hopper is positioned below the chamber for collecting coarser material which fails to enter the cage. The size of the volute can be adjusted by a vertical partition within the casing. The partition allows flexibility in setting the air velocity. Means are provided for stream-ling the air flow from the air inlet to the cage and retaining particles in the separation zone. In one case. louvers are provided for these two purposes, and in another case a screen is provided between the volute and particle separation zone.

Title: Sealing head
IPC: B29C65/02
Filed: 1989-05-23
Abstract: This relates to a sealing head for sealing 
lids to cartons. The sealing head (10) is provided with 
suction heads (26) or cups for receiving a lid from a lid 
supply and depositing such lid in position on a carton 
which is mounted in a nest. The sealing head is 
provided with a seal member (56) which forms the seal with a 
nest carrying a carton so that a vacuum may be drawn 
within the nest both within and around the carton. 
Thereafter, the sealing head provides an inert gas, 
such as nitrogen, to fill the carton with the inert 
gas, after which a support further sealing head moves 
the sealing head down further so that a lower edge of a 
projecting induction heating coil (24) will clamp a lid 
against a carton and effect a heat bonding of the lid 
to the carton. The sealing head is self contained and 
has a fitting including a plurality of electrical prongs (136,138) 
and fluid line sockets (140,142,144) for coupling the sealing 
head to a receptacle. Finally, the induction heating 
coil of the sealing head is of a special configuration 
so as to compensate for a pull tab carried by the lid, 
which lid is generally oval to match the oval carton. 
The outline of the coil deviates slightly from the oval 
shape so as to provide a seal which has a starting 
point to initiate peeling of the lid from the carton. 
Further, this starting point is aligned with the pull 
tab and there are current compensating pins (186,188) carried by 
the coil to compensate for the metal within the pull 
tab.

securing of the half-shells. A single lock element (40) is 
furthermore provided, which is supported by the lever (20) 
and is adapted to interact with the button element (17) and 
with the lever to prevent their actuation when the lock 
element is in closed position.

Title: Method of multicast message distribution
IPC: H04L12/18
Filed: 1989-07-05
Abstract: A method for multicast communication wherein a multicast message is distributed to all the nodes (101-118) in a multicast range. If a multicast message has a multicast range which is larger than one link in the network then the message is forwarded along a unique set of pathways through the range. The unique set of pathways is called a multicast spanning tree and is unique to all nodes which can communicate directly by virtue of a list of known nodes. The network is divided into areas (130-133) each of which contains a group of directly communicating nodes (123, 125, 127). A group of nodes (121-127) designated as level two nodes facilitates communication between the nodes in different areas.

Title: Methods and apparatus for efficient allocation of resources by optimizing nonlinear, convex functions with linear constraints
IPC: G06Q10/00
Filed: 1989-08-21
Abstract: A method and apparatus is described for optimally allocating 
resources. The optimal allocation is done by minimizing a cost (which is a 
convex non-linear function of various allocation variables) subject to different 
constraints (which are linear functions of the allocation variables). The method 
initially picks a state of the above variables  (x₀)  in the interior of the solution 
polytope (where the constraints are satisfied) and computes successive states 
 x₁,x₂ ,···, which progressively reduces the cost of allocation. The above iteration 
stops when suitable stopping rules are met.  
     The method employs (i) an affine scaling transformation (a variant of 
Karmarkar's projective transformation) of the linear constraints, (ii) an ellipsoid to 
sphere transformation of the curved cost surfaces, (iii) a potential search scheme 
on the curved constant cost surfaces, (iv) an affine scale adjustment mechanism, 
and (v) a line-search scheme.
