Title: Method for the continuous in-line contour edge molding of extruded plastic products and pattern roll for practicing such method
IPC: B29C48/07
Filed: 1988-02-24
Abstract: A method of forming a plastic product having 
contoured peripheral edges molded in a continuous 
in-line manner is described. A bounded recessed 
region is defined on at least a portion of a pattern 
roll's cylindrical surface. The pattern roll is then 
rotated in opposition to a platen roll so as to 
define a nip therebetween. Discrete volumetric 
portions of the recessed region are thus sequentially 
continuously presented at the nip upon rotation of 
the pattern roll. A molten thermoplastic is 
simultaneously extruded into the presented volumetric 
portions. Thus, this extrusion/rotation causes the 
thermoplastic material to fill the presented 
volumetric portions of the defined region, which 
filled portions will eventually form an outline of 
the plastic product and will, moreover, cause the 
thermoplastic material to be flowably compressed in 
the defined nip. This compression, in turn, allows 
the contoured edges to, in effect, be molded for each 
sequential volumetric presentation of the bounded 
region. Pattern rolls for practicing this method and 
a method of forming the same are also disclosed.

turning shaft (4) extending to outside the housing. The 
shape of the forward edge (8) of the closing face (7) of 
the closing member differs from the shape of the rearward 
edge (9). The characteristic curve is affected by the 
shape of the edge (8) of the closing face of the closing 
member at whose side the flow opening starts being formed 
when the valve is rotated from the closed position to the 
opened position. To change the characteristic curve 
and/or the maximum capacity, either one of the directions 
of rotation is chosen as the direction of opening of the 
valve.

Title: Method of manufacturing semiconductor device having elements isolated by trench
IPC: H01L21/32
Filed: 1990-06-13
Abstract: This invention relates to a method of manufacturing 
a semiconductor device having elements isolated by a 
trench. A trench (34) is formed to surround an element 
region (45) of a silicon substrate (32) by anisotropic 
etching. A nonoxide film (40) such as a silicon nitride 
(SiN x ) film is selectively formed on the upper surface 
of the element region (35). Thermal oxidation is per­
formed using the nonoxide film (40) as a mask to form an 
oxide film (43) on the inner face of the trench (34) and 
the upper surface of a field region (42). Thereafter, a 
polysilicon layer (44) is buried in the trench (34), and 
after the surface of the polysilicon layer (44) is 
flattened, a capping oxide film (45) is formed on the 
upper surface of the trench (34). In addition, a 
nonoxide film (40) is formed to have an interval between 
the end of the nonoxide film (40) and the trench (34) of 
2 µm or more.

Title: Clock regeneration circuit for a clocked information processing system
IPC: H03K5/01
Filed: 1990-10-23
Abstract: Line trunk groups exist in duplicate for dependability reasons. The through connection of the input lines to the switching network can thus run via different signal paths. To avoid interference during the switch-over, the interfaces concerned are provided with compensating buffers. The data contained therein are read in and out phase- and frame-synchronously with a uniform clock. This uniform clock is obtained from the basic digital TDM switching system clock. Due to transit time distortions and component tolerances, this basic clock must be regenerated by the circuit arrangement according to the invention before it is applied to the compensating buffer.

Title: Apparatus and method for producing weighed charges of loosely aggregated filamentary material from compacted bales of the material
IPC: D01G29/00
Filed: 1985-08-12
Abstract: @ Bales of filamentary material are separated into weighed charges of the material by disintegrating the bales in a rotating drum to produce tufts that are passed to a picking chamber wherein a toothed roll strips individual filaments from a supply roll formed from the tufts and passing the filaments to scales upon which the charges are accumulated. Each time a charge is accumulated on a scale, air is blown across the scale to discharge the scale. The charges are delivered to a magazine having a plurality of vertically stacked chambers, each chamber underlain by a movable gate, through which the charges are passed sequentially to be discharged at a fixed schedule from the lowermost chamber. Spikes mounted on the interior of the drum are shaped to loosen portions of bales entering the drum, tear tufts from such portions, and finally deposit the tufts into an air stream passing through the drum to expel the tufts. Between the drum and the picking chamber, the tufts are treated with an anti-static compound in a chamber through which the tufts fall while a mist of the compound is injected into the chamber. Above the picking chamber, the tufts enter a deflection tower and are deflected to one side or the other of the picking chamber to concentrate the supply roll at one side of the picking chamber and filaments to each of two scales are drawn from opposite sides of the picking chamber.

complementary to the targeted nucleic acid, which 
fragment is attached to nonporous, nonmagnetic 
particles. An insoluble hybrid is thus formed which 
is then separated from the specimen. After 
dehybridization, the purified targeted nucleic acid 
is available for further use, such as amplification 
by polymerase chain reaction and detection.
Patent EP-0402120-A3 (EP)
Title: Countercurrent separation process and apparatus
IPC: C08J9/00
Filed: 1990-06-06
Abstract: A multistage countercurrent separation apparatus and 
method is described. Each stage includes a mixer zone (M) 
and a settler zone (S), both of which have temperature 
control means to achieve a first temperature in the mixer 
zone and a seoond temperature in the settler zone. 
Solvents used in the process are selected so that they have 
at least one immiscibility transition temperature such that 
they form a single homogeneous phase at said first 
temperature and two heterogeneous phases at said second 
temperature. By carrying out the process, a solute or 
solutes introduced into the system may appropriately be 
efficiently concentrated or separated with minimal 
agitation. Furthermore, because emulsification by rapid 
agitation is avoided, the homogeneous phase quickly 
coalesces upon passing into the heterogeous phase, thereby 
increasing the throughput which may be achieved by the 
extraction process.
