Abstract: An imide having the structural units of the formulae (I) 
and (II), or (I), (II) and (IV), 
  
is soluble excellently in a low-boiling sol­
vent and can give alone or together with one or more amides, 
epoxy compounds, unsaturated polyesters, diallyl phthalates, 
or the like, heat resistant polymers. The imide can be pro­
duced by, e.g., reacting tetrahydrophthalic anhydride with 
aniline resin with or without followed by dehydration and ring 
closure, reacting the resulting reaction product with an ethy­
lenically unsaturated carboxylic acid anhydride such as 
maleic anhydride, followed by dehydration and ring closure.

Patent EP-0068678-A3 (EP)
IPC: G06F7/02
Filed: 1982-06-09
Abstract: A magnitude comparator circuit is provided for de­
termining the largest binary number, out of a plurality 
of binary numbers received bit-serially, in parallel. A 
latch is used to store the results of the comparison 
and is initialized to an all logic 0 state. The latch has a 
unique one-bit location corresponding to each number 
being compared, and a logic 0 stored in the latch in­
dicates that the number corresponding thereto is still in 
contention (i.e remains a candidate) for being the lar­
gest, and a logic 1 indicates it has been eliminated 
from contention. As the numbers are received bit by bit 
(most significant bits first) the bits are applied to gating 
circuits, one for each number, which invert the bits and 
store the inverted result in the latch. The exceptions 
to this are twofold; a) when a number has already been 
eliminated from contention, as indicated by a logic 1 
stored in the latch corresponding to that number, it 
remains a logic 1; and b) when the remaining candidates 
all have a binary 0 in an equal significant bit location 
no choice is of course possible and the aforestated in­
version does not take place and the contents of the latch 
are simply recycled.

Abstract: An improved vapor phase process for chlorosulfonation 
of polyethylene, particularly in a fluidized bed, is accom­
plished by treating a mixture of powdered polyethylene, and 
finely divided inorganic compounds having a dielectric 
constant of greater than about 40 and specific conductivity 
greater than 10⁻¹³ to less than 10⁻¹ (Ω⁻¹ cm⁻¹), such as 
titanium dioxide, with chlorine and sulfur dioxide, optionally 
under actinic light, at an initial temperature from about 20°C 
to about 70°C and raising the temperature of the reaction to 
at least about the crystalline melting point of the 
polyethylene and continuing the reaction until the 
polyethylene contains about 25 to 45 weight percent bound 
chlorine and 0.5 to 3 weight percent sulfur to provide 
improved vulcanizable elastomers. In the fluidized bed 
process, improvement is obtained in bed mixing and heat 
transfer, with minimum polymer deposition on reactor walls 
and polymer agglomeration, essentially eliminating channel­
ing and bed breakdown.

IPC: G11B5/09
Filed: 1984-04-24
Abstract: A thermo-magnetic method for recording of a bit of 
information in each domain of an amorphous alloy thin-film 
layer supporting small stable domains. Each domain in the 
recording layer is first magnetized in a first direction, corres­
ponding to a first binary state, by exposure to a saturation 
magnetic field. The remaining binary state is temporarily or 
permanently recorded in a particular domain by heating (to a 
lower or higher temperature) that domain volume of the 
recording layer and thereafter cooling the heated domain in 
the presence of a bias magnetic field of direction opposite to, 
and magnitude less than, the saturation field. The binary 
state of each domain is read by interrogation with a beam of 
energy and utilization of differential effects between the 
interrogation beam and the direction of the magnetic field in 
the interrogated domain.

Title: Ready-to-assemble staircase system featuring modular components
IPC: E04F11/035
Filed: 1984-04-06
Abstract: The invention relates to a staircase system featuring modular construction components, wherein the framework of the staircase itself is produced by assembly of such modular components (1) & (2) paired one with the next in sequence so as to form a bearing structure for the single stair treads.Components (1) and (2) are prismatic in shape and slot together reciprocally in a number of positions one with respect to the other so as to give a variation in relative distance - at least, in the vertical plane.Each modular component consists of a length of moulding whose cross section exhibits an elongated profile which remains constant throughout; the moulding disposed with its main longitudinal axis horizontal following assembly.The reciprocal type of join between one component and the next is brought about by joining means incorporated into the vertical side faces of one component (1) and into the mutually-opposed inwardly-set vertical faces of the next component (2), between which the first component (1) is part-inserted. Once interlocked thus, the joining means inhibit any reciprocal movement whatever of either component (1) or (2) other than parallel to the horizontal axes of the individual mouldings used for their embodiment.

Abstract: A radio position determination and message transfer 
system is implemented using a number of satellites in 
geostationary orbit for relaying interrogation and reply 
signals between a ground station and a user-carried trans­
ceiver. Message information can be exchanged between a 
given user transceiver and the ground station, as well as 
between different user transceivers. The user transceiver is 
provided with means for monitoring the quality of the radio 
communication link between the transceiver and one or 
more of the satellites, based on errors detected in the 
received interrogation signals. The transmission of a reply 
signal by the transceiver is enabled only when the link 
quality is found to be acceptable. The reply signal may 
contain message information or may constitute a request for 
a position fix. In the latter case, the transceiver may be 
configured to await favourable link quality to more than one 
satellite before the reply signal is transmitted.

Title: Combing-roller for an open-end spinning device
IPC: D01H4/32
Filed: 1986-07-03
Abstract: The opening cylinder comprising a cylindrical ring serving as a needle support and being provided with needle-housing bores extending from the inner ring surface to the outer one is designed to carry needles comprising a point section of gen- eratlh tapered shape and a shaft section, the latter being pressed Into and seated with force fit in a radially inner section of a corresponding one of said bores. A radially outer section of the bore surrounds a portion of said needle point section so as to form an annular groove therearound at the orifice of the bore in the outer ring surface. The radially inner section of the bore or at least part thereof has a diameter which is at least as great as the diameter of the outer section of the bore in the range of its orifice in the outer ring surface. This ensures having a simple and inexpensive needle mounting with a precise positioning of the needle tips protruding above the outer ring surface and with a secure holding of the needle shaft sections not only by press fit, but also by form fit connection due to the expansion of the inner bore section receiving the needle shaft section and the correspondingly lesser diameter of the outer bore section. The latter thus forms a bead or shoulder in front of the radially outer end edge of the needle shaft section establishing said form fit connection.
