Title: Folding display frame
IPC: G09F15/00
Filed: 1987-12-09
Abstract: A collapsible framework constructed of rods pivotally joined at their ends to hubs to form a self-standing unit when expanded and to fold into a small set of nearly parallel rods when folded. The hubs are designed to pivotally join the ends of four rods, with the plane defined by the pivot axes of one pair of opposing rods being offset from the plane defined by the pivot axes of the other pair of opposed rods attached to the same hub. A stab-connection latch locks two hubs together and secures the framework in the expanded position. Folding channel bars are attached to knobs on vertically aligned hubs by key-slots, the key-slots of one channel bar being of progressively shorter length going from the top-most to the bottom-most of the vertically aligned hubs to which the bar is attached. <IMAGE>

Title: Oligomer flame-retarding additive, process for its preparation and its use for endowing a linear polyester with self-extinguishing characteristics
IPC: C07F9/40
Filed: 1987-07-14
Abstract: An oligomer flame-retarding additive can be defined by the general formula <CHEM> wherein: R is the hydrogen atom, or a linear or branched alkyl radical, containing from 1 to 6 carbon atoms;  m takes the value 1, 2 or 3; n takes a value, or an average value, comprised within the range of from 2 to 50. Such an additive is obtained by means of the oligomerization of a hydroxyalkylenephenylphosphinic acid or of a related alkyl ester thereof. According to another form of practical embodiment, the flame-retarding additive is the product of co-oligomerization of a hydroxyalkylenephenylphosphinic acid, or of a related alkyl ester thereof, with a phenylphosphonic acid or a related alkyl ester thereof. Such oligomer additives are used for endowing a linear polyester with self-extinguishing characteristics.
Patent EP-0231116-A3 (EP)
IPC: F25B9/00
Filed: 1987-01-26
Abstract: This publication describes a method and apparatus for the 
utilization of heat energy released in a cooling process. 
In accordance with the method, air used as the heat transfer 
medium is routed to a compressor (2) in which compressor (2) 
the air is compressed to a higher pressure, the compressed 
air is cooled to a lower temperature, the cooled air is routed 
to a turbine (8), where it expands to a lower pressure and 
cools down, and air expansion work released in the turbine 
(8) is used for rotating the compressor (2). In accordance 
with the invention, air is compressed in the compressor (2) 
to such a high pressure that its temperature exceeds a minimum 
temperature of water boiling point in normal atmospheric pres­
sure, the high-pressure compressed air is cooled to a suffi­
ciently low temperature, e.g., below 15 °C, by means of at 
least one heat exchanger (4, 6) in order to prevent freezing 
in the turbine (8); the heated medium from the secondary cir­
cuit of the heat exchanger (4, 6) is utilized as such, e.g. as 
hot water, and air is routed from the turbine (8) as such, 
to the object to be cooled. The method allows the use of 
the heating medium as such for cooling purposes.

IPC: C08L65/00
Filed: 1987-07-16
Abstract: A polymer composition containing a major proportion of 
polyarylketone, balance polyimide is used as an insulating coating 
for an electrical conductor or as the polymer constituent of a filled 
polymer composition. The polyarylketone preferably contains one or 
more of the units  
I - Ph - O - Ph - CO;  
II - Ph - O - Ph - O - Ph - CO;  
III - Ph - O - Ph - Ph - O - Ph - CO  
The coated electrical conductors show advantageous pliability and 
resistance to environmental cracking. The filled compositions can 
have a higher glass transition temperature than corresponding 
composition containing no polyimide, while retaining high resistance 
to organic solvents.
Patent EP-0257816-A3 (EP)
IPC: H04L12/56
Filed: 1987-07-29
Abstract: The present invention relates to an N-input, N-output "Knockout" 
packet switch (11) which uses decentralized control and distributed routing for 
routing high-speed, time-multiplexed, variable-length packets of information 
from the N inputs to the N outputs. More particularly, within the switch, the 
N input signals are separately synchronized such that the start of each 
arbitrarily arriving variable-length packet is synchronized to the start of a next 
mini time period of a sequence of mini time periods common to all inputs. The 
synchronized N input signals then propagate along separate broadcast buses 
(14) to each of N bus interface units (15) which include N packet filters (20), a 
concentrator (21) and a shared buffer (22) capable of processing variable-length 
packets. Each bus interface unit is associated with a separate one of the N 
outputs (12) of the switch, and the N packet filters therein are each associated 
with a separate one of the N broadcast buses for detecting if a packet on the 
associated bus is destined for the associated switch output. The concentrator is 
used to (a) reduce the number of separate buffers needed to receive packets 
which may arrive simultaneously and are destined for the associated output, 
and (b) only directs a maximum of L concurrently arriving packets to the shared 
buffer while discarding, or "knocking" out, the remainder. Contending packets 
at the output of the concentrator are stored in the shared buffer before 
placement on the output line on a first-in, first-out basis. The discarded packet 
rate of the "Knockout" switch can be made as small as desired and latency of 
packets in the switch is the smallest achievable by any comparable switch.

Title: Suspended filing system
IPC: B42F15/00
Filed: 1988-08-11
Abstract: The suspended filing system consists of document bearers having in each case at least one suspension fitting and of at least one suspension bearer for suspending the document bearers. Each suspension fitting, attached to the upper edge of the document bearer, has a recess with a slot-shaped region formed by a tongue. Said slot-shaped region is composed of a partial region of greater width and an adjoining partial region of reduced width. The suspension element has at least two profile portions, a first one of which corresponds in its length and width to the partial region of the suspension fitting of reduced width and a second profile portion corresponds in its length and width to the partial region of the suspension fitting of greater width, with the result that a simplified pushing-on of the respective suspension fitting onto the suspension element is possible, but, at the same time, a form-fit is produced between the suspension fitting and the suspension element. <IMAGE>

Abstract: A wafer scale integrated circuit wherein at 
least one of a plurality of functional blocks (2) 
formed on a semiconductor wafer (1) has its internal 
defects repaired and has an area which is at 
least 2.3 cm². The integrated circuit permits the

much greater than that of the conventional blocks. 
Therefore, the total length of wirings among the 
blocks can be shortened to simplify the complex 
wiring process, the total number of wiring layers 
can be reduced, and the signal propagation delay 
time can be shortened, too, making it possible to 
realize a high packaging density with low redundancy.

Patent EP-0366847-A3 (EP)
Title: Graphics display using biomorphs
IPC: G02B6/35
Filed: 1988-12-20
Abstract: A bimorph using ultraviolet setting glue to 
laminate a piezoelectric film structure, having 
etched-back metalization patterns on the surfaces of the 
piezoelectric film. The bimorph is used in a bimorph 
light modulator including a substrate on which fiber 
optic input and output light guides are mounted. A gap 
between the light guides serve as an optical coupling. 
A bimorph is affixed to the substrate with a shutter 
attached to one end thereof and positioned within the 
gap for blocking the light coupling when the bimorph is 
in the unenergized state. When the bimorph is 
energized, it pulls the shutter out of the gap, thereby 
allowing light coupling. Top and bottom stops are used 
to limit the bimorph movement to damp resonant 
vibrations and improve on and off times. Viscous air 
damping is used to eliminate or minimize bounce of the 
top and bottom stops and to help damp resonant 
vibration.  
     An array of the bimorphs may be utilized for 
providing a video or other display, with electrode 
connections being made to the bimorphs by means of 
conductors which contact the bimorph electrodes at small 
surface areas, with the conductors being attached to 
circuit boards carrying signals for operating the 
bimorph array. The optical fibers may be coupled to 
different light sources and filters to provide color 
images, and groups of optical fibers may be arranged to 
form pixels for providing a broad range of intensities.
