Title: Shutter
IPC: E06B9/56
Filed: 1986-12-02
Abstract: A roller shutter is described which has a roller (l3) arranged with its axis vertical, so that the shutter curtain (l0) is extended laterally in use. The weight of the curtain (l0) is supported in the extended condition from a top track (l4) having internal running surfaces (35) co-operating with roller wheels (34) of a top chain (29), to which the articulated laths (ll) of the curtain are, in turn, attached. Constant tensioning means (l8-­25) are provided for the curtain, which can follow a straight, angled or curving path. The bottom chain (9) of the curtain may have depending skirts (42), interfitt­ing (at 43, 45) to reduce fire penetration. A lead-in guide (50) of the roller housing (l2) has a lifting ramp (53) co-operating with ball glides (38) of the bottom chain to lift the curtain (l0) gently onto, and off, the top track (l4) running surfaces (35) on leaving and re-­entering the housing (l2).

Patent EP-0245747-A3 (EP)
IPC: H05K1/18
Filed: 1987-05-05
Abstract: Diese Anordnung dient zur exakt symmetrischen Ansteue­
rung einer Vielzahl von parallelgeschalteten, im Schalt­
betrieb arbeitenden Leistungs-Feldeffekttranssistoren 
(T1...T30). Hierzu sind die Transistoren auf einer Auf­
bauplatine (6) von länglicher Form derart angeordnet, 
daß zwei sich gegenüberliegende Reihen gebildet werden. 
Räumlich benachbarte Transistoren sind jeweils zu einer 
Gruppe zusammengefaßt. Zu jeder Gruppe führen zwei Sam­
mel-Ansteuerleitungen (4a-e und 5a-e), die über zentrale 
Sammel-Anschlüsse (22a-e, 23a-e) auf der Aufbauplatine 
(6) und jeweils gleichlange Leiterbahnen (24,25) mit den 
einzelnen Transistoren verbunden sind. Auf diese Weise 
ergibt sich eine "sternförmige" Ansteuerung der einzel­
nen Transistoren jeder Gruppe, d.h. eine Ansteuerung mit 
gleichlangen Ansteuerwegen. Die Sammel-Ansteuerleitungen 
(4a, 5a-e) sind ebenfalls von gleicher Länge, und je­
weils zentral miteinander verbunden. Die Aufbauplatine 
(6) kann mit Bauteilen (7) zur Einzelbeschaltung der 
Transistoren bestückt sein. Die Lastanschlüsse erfolgen 
über eine mit der Aufbauplatine (6) verlötete U-förmige 
Stromschiene (1) und über einen mit den Transistoren 
kontaktierten Kühlkörper (9). Anwendungsgebiete liegen 
in der Leistungselektronik, z.B. bei Gleichstromstellern 
für Maschinen mit hohem Strombedarf.

Patent EP-0271857-A3 (EP)
IPC: H01K1/18
Filed: 1987-12-14
Abstract: This invention provides an improved compact fine 
wire incandescent lamp filament and method for making 
the same. The filament has a primary mandrel ratio in 
the range of about 1.40 to about 4.00 and a secondary 
mandrel ratio which is greater than or equal to the 
primary mandrel ratio. The length between supports is 
kept less than or equal to 20 times the secondary 
diameter.  
     The improved filament design exhibits an increase 
in compactness and retains or increases structural 
rigidity while exhibiting minimal sag when the filament 
is incorporated into an incandescent lamp of the 
tungsten halogen type variety.  
     The compact coiling method is particularly useful 
in designing compact filaments for high voltage 
applications where it is desirable to eliminate the use 
of rectifying means to lower the effective voltage 
across the filament.
Patent EP-0240102-A3 (EP)
IPC: G01R21/133
Filed: 1987-01-20
Abstract: An electronic metering system having self-test 
capabilities. First and second analog signals are 
produced which are indicative of the voltage and 
current, respectively, carried on a line. The first 
analog signal is modulated to provide a digital signal 
changeable between two levels at predetermined clock 
times. The ratio of duration of the signal at one 
level to that of the second level is proportional to 
the line voltage. The modulated signal and second 
analog signal are multiplied together to produce a 
product signal which represents power carried on the 
line in either direction. The product signal is 
converted to a train of pulses, with each pulse 
representing a predetermined amount of power. Self-­
test capability is provided wherein a test signal is 
momentarily substituted for the first analog signal, 
with the test signal corresponding to a line voltage of 
zero magnitude. A comparator is provided for 
confirming that the converted product signal 
corresponds to zero power carried on the line in either 
direction when the test signal is applied. If the 
converted signal differs from zero power more than a 
predetermined amount, an error signal is produced 
indicating a meter system malfunction.

Title: Valve
IPC: F16K1/34
Filed: 1987-05-15
Abstract: A diaphragm-type valve uses a multiple annular metal diaphragm (36) welded about its inner periphery to a valve operating stem (34). The diaphragm is sealingly clamped about its outer periphery to the valve body and is also clamped about its inner periphery at a location spaced outwardly of the weld to prevent the weld from being subjected to flexure stresses during valve actuation. The outer periphery of the diaphragm (36 min ) may be welded to the valve body (10 min ) outwardly of the outer clamp. The actuating assembly (20) is arranged to produce non-rotary, reciprocatory movement of the operating stem (34) through a bonnet mounted rotary actuator (116). A stem tip seal (16) comprises a metallic seal ring (152) backed by a PTFE ring (158) and surrounded by a harder plastics ring (160) held captive by a sleeve (166).

Title: Apparatus for continuous casting of fused materials, particularly metal oxides
IPC: B22D11/06
Filed: 1988-02-18
Abstract: If a liquid metal oxide is fed to the nip of an inwardly cooled pair of rolls to cool and solidify, the rolls are subjected to a great material fatigue because of the constantly changing high heat stresses. A configuration of the rolls with few notches can be achieved by an approximation of the contour of a spherical hood. This is achieved in that each of the rolls (1,2) is designed as a truncated conical section, in that adjacent to the base (9,10), exhibiting the greater diameter of each truncated conical section a cylindrical section (5,6) with the diameter of the base (9,10) and a substantially open front surface (23) is provided. Each truncated conical section is closed, by a plane wall, on the front surface (7,8) with the smaller diameter.

Abstract: A device is provided for increasing the distance 
between the power head (12) and bit (20) of a power 
screwdriver, particularly one intended for driving 
drywall screws. The device includes a polygonal 
drive rod (26) which replaces the original drive rod in

Abstract: A database system in a data processing system has an index tree structure 
with a root node having reference keys to nodes in the next lower level 
and so on until bottom nodes having keys referencing the database 
records. Multiple users may access the database concurrently. 
Transactions in which the tree structure is to be modified (for example 
removal of a record) are performed by traversing the tree to the 
appropriate bottom node and setting an indication of pendency of the 
modification. At the same time other accesses to the database, through 
nodes at which no tree structure modifications are to take place, can 
continue. When the structure modification has been performed, a log 
record of it is made to prevent undoing the modification in the event of 
a system failure, and database access through all the bottom nodes then 
continues.
