5000 H z , an dem Beschichtungsmaterial oder an dem zu be­
schichtenden Körper über die gewünschte Beschichtungszeit

Title: Semiconductor memory system
IPC: G11C11/401
Filed: 1988-11-02
Abstract: In a semiconductor memory system of the serial 
column access type, a redundant column (55) is used for 
replacing a defective column. Redundant data lines (SD, 
 SD ) are connected to the redundant column (55) through a 
redundant column selection gate (15). A defective 
address detection circuit (43) detects the address of a 
defective column to enable the redundant column selec­
tion gate. An address counter (42) is provided for a 
defective address detection circuit (43). A redundant 
column selection circuit (25) selects the redundant 
column in response to a detection signal from the defec­
tive address detection circuit (43). A data line 
switching circuit (41) switches, in redundant column 
select mode, the data lines connecting to a data 
input/output drive circuit from said regular data lines 
(D,  D ) to the redundant data lines (SD,  SD ). With this 
circuit arrangement, in a redundant column select mode, 
the regular data lines are separated from the data 
input/output drive circuit. Therefore, even if a shift 
register constituting a regular column selection circuit 
(21₁ to 21n) operates and the defective column selection 
gate is enabled to set up a connection of the defective 
column to the regular data lines, the error data from 
the defective column is never output. Further, the 
shift register is operable irrespective of the defective 
column detection.

Abstract: A sign (10, 40, 50, 60, 70) is made by a pultrusion 
process by printing separate sign panels (36, 46, 53, 66) 
and attaching them to a fibrous component (32, 43, 54, 62) 
of the sign (10, 40, 50, 60, 70) to make a longitudinally 
continuous sign panel subassembly (32/36, 43/46, 54/53, 
62/66) which is beneath the surface of the sign (10, 40, 
50, 60, 70). The sign panels (36, 46, 53, 66) are spaced 
apart in the subassembly (32/36, 43/46, 54/53, 62/66) by 
about the length of the sign (10, 40, 50, 60, 70) and are 
fixed to the fibrous component (32, 43, 54, 62) prior to 
being pulled through a forming die (17). In the forming 
die, the subassembly (32/36, 43/46, 54/53, 62/66) is formed 
together with rovings (31, 41), scrim (30), resin and any 
other components of the sign (10, 40, 50, 60, 70) into the 
cross-section of the sign (10, 40, 50, 60, 70). The sign 
panel subassembly (32/36, 43/46, 54/53, 62/66) saturates 
with the resin so that it blends in with the rest of the 
sign (10, 40, 50, 60, 70) except for identification matter 
(12) printed on it and is permeable to allow gases to 
escape as the resin cures in the die (17). The sign (10, 
40, 50, 60, 70) takes on its desired cross-sectional shape 
in the die (17) and is cut off at its desired length after 
it exits the die (17). The sign panel (36, 46, 53, 66) may 
be on either side of the subassembly (32/36, 43/46, 54/53, 
62/66), and the subassembly (32/36, 43/46, 54/53, 62/66) 
may be beneath a surface layer (42). The fibrous component 
 
 
(32, 43, 54, 62) of the subassembly (32/36, 43/46, 54/53, 
62/66) may be continuous, or may be in sections spaced 
apart and affixed to the sign panels (36, 46, 53, 66). A 
double sided sign (50) may be made by attaching pairs of 
sign panels (53) side by side to a fibrous component (54) 
which can be folded to display the sign panels (53) on both 
sides of the sign (50).

chemically reacting a particulate kaolin with a metal chloride, 
such as silicon tetrachloride, and with urea or an organic amine. 
The process is conducted under conditions such that the kaolinite 
structure is not altered.

Title: Drum screen
IPC: B07B1/22
Filed: 1989-01-19
Abstract: The subject of the invention is a drum screen for conditioning and classifying granular material with an input device at the one end of the drum which rotates about its lying longitudinal axis and an output device for the conditioned material at the other drum end. The output device connects to an annular space which is formed between the drum and annular screen sections which are located one after the other in the longitudinal direction of the drum and concentrically surround the drum. The mesh width of the annular screen sections changes in such a way that the section with the smallest mesh width is the annular screen section nearest to the output device and the section with the largest mesh width is the annular screen section at the greatest distance from the output device, preferably located in the region of the input device. Between every two successive annular screen sections (7a, 7b), a channel-shaped profile (29), with the open side directed outwards, concentrically surrounds the drum (2) at a distance of the width of the annular space. The profile engages with a number of hook- shaped mounting elements (28), distributed over the circumference, over the respective profile flange of the annular screen sections ending at it, the annular screen sections being located with initially still extended hook parts (28b) essentially free of play between two channel profiles spaced in the longitudinal direction of the drum and being held after installation in the installation position with the hooks bent about the free flange ends during installation. <IMAGE>

Title: Fluorocarbon elastomers crosslinked by ionizing radiation
IPC: C08L27/16
Filed: 1989-08-23
Abstract: A fluorocarbon elastomer having remarkably high 
tensile strength, high modulus in tension, and excellent 
retention of tensile strength at elevated temperatures, 
made from a copolymer of vinylidene fluoride and at least 
one copolymerizable fluorine-containing monomer blended 
with a polyfunctional acrylate and exposed to high-energy 
ionizing radiation to crosslink the copolymer. No thermal 
curing agent needs to be used unless the elastomer is being 
molded to form a shaped body such as an O-ring or a gasket. 
Even then, the preferred amount of thermal curing agent is 
only about one-fourth the amount used in the prior art for 
crosslinking such fluorocarbon elastomer copolymers. The 
fluorocarbon elastomer is especially useful as fuel line 
tubing and can be so used without a jacket.

Title: Atm switch with copy capability
IPC: H04L12/56
Filed: 1991-01-29
Abstract: Starting point: The sequence is known of a copying switching matrix, a distribution switching matrix and a destination switching matrix on the one hand, and on the other hand a switching matrix in which copying can be carried out in every stage. 
<??>Technical problem: Real operation is a mixture of point-to-point connections, point-to-multipoint connections with few branches and point-to-multipoint connections with many branches. The overall traffic and its individual constituent parts are constantly changing. The known structures are optimised in each case for one specific traffic type in one direction only. 
<??>Fundamental concept: The switching elements of a switching matrix which is optimised for point-to-point connections contain the additional facility for copying a small number of input signals for any number of outputs, whereby a very large number of copies can be achieved overall for a very small number of input signals. This switching matrix is supplemented by a copying switching matrix, which serves solely to produce in each case a limited number of copies for a large number of input signals, which are then switched in the (main) switching matrix as point-to-point connections. 
<??>Solution: Point-to-point connections are operated as "connectionless connections" by means of automatic switching element control. It is ensured that these connections act outwardly as virtual connections. Point-to-multipoint connections are also operated in the main switching matrix as virtual connections (connection-oriented) by means of connection tables. 
<??>Advantage:Interference-free rearrangement of existing virtual connections possible. Very even utilisation of the (main) switching matrix as a whole. 
<??>Disadvantage: Switching elements with two different addressing facilities required.
