Patent EP-0202110-A3 (EP)
IPC: E04B9/02
Filed: 1986-05-13
Abstract: A clean room having provision for supplying filtered 
air vertically therethrough under substantially laminar 
flow conditions includes a filter bank (16) comprising 
a supporting latticework (30) composed of a plurality 
of interconnected members which define rectangular 
open areas, and a plurality of high efficiency air 
filters (74) positioned on the supporting latticework. 
Each of the members (34,36) of the latticework has 
a generally V-shaped outline in cross section with 
the angular extent of the V-shaped outline being adapted 
to provide a substantially laminar flow therealong, 
and so as eliminate any substantial turbulence below 
the members (34,36) of the latticework. Such turbulence 
has been found to entrain dust or dirt particles and 
move the same laterally through the room, and the 
elimination of such turbulence effectively eliminates 
lateral migration of dust or dirt particles.

Abstract: An apparatus (10) for refining fibrous materials such as 
stock suspensions for papermaking which includes a hous­
ing (11), an inlet and outlet in said housing for receiving and 
discharging the treated materials, a shaft (12) rotatable in 
said housing, a plurality of rotating refiner disks (30 to 35) 
spaced along the shaft (12) and an additional plurality of re­
finer disks (41, 42, 51, 52) interspersed with the rotor disks (30 
to 35) and providing therewith refining gaps (43, 44, 55, 56) 
through which the stock suspension passes. The other re­
finer disks (41, 42, 51, 52) can be either stationary or counter-­
rotating with respect to the rotor disks. The two sets of refiner 
disks are supported by means of axially flexible membranes

disks (30 to 35, 41, 42, 51, 52) which have undercut portions 
in the surfaces adjacent to the flexible annular membranes 
(24, 25, 26, 46, 54) to increase the axial flexibility of the mem­
branes.

Title: Solid block chemical dispenser for cleaning systems
IPC: B65D77/20
Filed: 1986-10-31
Abstract: A substantially horizontal support screen (40) within a housing (20) retainably supports a solid block of wash chemical (80) thereabove. The support screen divides the housing into an upper cylindrical storage portion (21) and a lower funnel shaped collector portion (25). A spray forming nozzle (38) is mounted within the collector portion below the generally horizontal screen (40) for directing a spray of water at substantially the entire downwardly facing surface (81) of the wash chemical block supportably retained above the support screen. The dissolved wash chemical passes through the support screen, is collected by the collector portion of the housing, and directed to its utilization point. Spray control means (43), either manual or electronic, control the spray of water through the nozzle in response to a control signal. The dispenser is configured for mounting to a vertical surface and is loaded through an upper access port (24) normally closed by a door (34). A safety switch (50) prevents the spray of water from the nozzle whenever the door is open.

IPC: G11B20/12
Filed: 1987-02-19
Abstract: A method of decoding digital synchronizing signals each of 
which consists of a plurality of bits in a predetermined pattern, 
the intervals between the starts of succesive synchronizing 
signals in an input digital signal being variable over a range, 
comprises ascertaining the bit period distance between the 
starts of two successive synchronizing signals, subsequently 
searching the input digital signal for the pattern using a window 
comprising the bit period distance, which window is varied in 
position if the bit period distance changes, and supplying an 
output synchronizing pulse in synchronism with subsequent 
synchronizing signals found in the window.
Patent EP-0243063-A3 (EP)
IPC: H03C3/02
Filed: 1987-04-13
Abstract: An angle modulator operated intermittently for the reduction of the 
power consumption of radio 
equipment, and so on, receives a frequency control voltage and an input 
modulating signal at different terminals of a variable 
capacitance diode (D) so that the 
frequency control voltage is applied directly to 
the variable capacitance diode 
without being affected by the coupling capacitor 
for the modulating signal. 
This allows a quick response to the frequency control signal 
and a rapid tuning after the start-up of the modulator.

Patent EP-0290097-A3 (EP)
Title: Support leg joint construction with bracing
IPC: F21V21/02
Filed: 1988-05-03
Abstract: A support leg (16) includes an insert (20) within a tubular upper portion (18). Threaded engagement is made between the threaded opening (22) in the insert (20) and a stud (14) which is welded at its upper end to an overhead structure (10). The tubular portion (18) extends through an opening in the small end (34) of a conical brace member (32). The small end (34) of member (32) is welded (38) to the member (16). A large diameter upper end (36) of brace member (32) extends axially outwardly beyond the end (42) of member (16). Rotation of member (16) relative to the stud (14) tightens the screw joint (14, 22) and forces the upper end (36) of brace member (32) into tight contact with the overhead member (10). The weld (42) is harder than the member (16), resulting in a galling of the upper end (42) of member (16), during the rotation. This galling makes a tight contact fit between end (42) and weld bead (44). This type of fit braces the member (16) against upper end sideways movement in response to a sideways load on member (16).

Title: Method and apparatus for monitoring analytes in fluids
IPC: G01N33/52
Filed: 1988-03-17
Abstract: The invention includes a photometer (10) and 
a photometric test strip (31) for use with the photo­
meter for monitoring the presence and amount of an 
analyte in a liquid sample. The photometer (10) 
includes a light source (25) and a photodetector (26) 
which form an optical path for detecting light trans­
mitted through a test strip (31). The latter has a 
dry support and an indicator portion, both of which 
allow light of predetermined frequencies to be trans­
mitted therethrough. The photometer (10) includes 
an electrical circuit (21) for generating a signal 
proportional to detected light and for generating an 
output signal representative of the presence and amount 
of the analyte in the sample of blood being monitored. 
In a preferred embodiment, the invention includes the 
use of a nonbibulous test strip (31) having a nonbibulous 
indicator portion thereon through which light is trans­
mitted and detected following deposition of a blood 
sample thereon. The photometer may be calibrated to 
produce an output reading and resonse to the trans­
mitted light which is representative of the milligram 
percentage of glucose in the blood being monitored.

Title: Method of forming a metal article from powdered metal
IPC: B22F3/12
Filed: 1988-12-21
Abstract: A container (42) for holding powdered metal (44) is formed by 
electroplating a layer of metal over a pattern having a 
configuration which corresponds to the configuration of an 
article to be formed. A rigid core (32) is surrounded by the pattern 
material and the layer of metal. The pattern material is removed 
from the layer of metal to form a container in which the core is 
disposed. The core and container may be held against relative 
movement by gripping the core with the layer of metal or by pin 
elements extending between the core and layer of metal. The 
container is filled with metal powder. The metal powder is cold 
compacted to plastically deform the particles of metal powder 
without significant bonding between the particles of metal 
powder. The metal powder is cold compacted by exposing the 
container to fluid at a relatively low temperature and high 
pressure. Metal powder particles are pressed against each other 
and against the core by the fluid pressure (50) applied against the 
container to plastically deform the metal powder particles. 
After being cold compacted, the metal powder is hot compacted to 
bond the particles of metal powder together and form a unitary 
body which surrounds the core. The core is subsequently removed 
from the unitary body to form a recess in the body.
