Patent EP-0365085-A3 (EP)
IPC: H03G1/00
Filed: 1989-10-13
Abstract: Eine Schaltungsanordnung zum Einstellen der Amplitude eines Signals 
(2) benutzt einen Multipilizierer (11) mit Zwei kreuzgekoppelten 
Differenzverstärkern (18, 19), die durch eine Steuerspannung (28) 
kontrolliert werden. Das Signal (2) liegt am Eingang eines Stromspiegels 
(8), dessen Ausgang den Differenzverstärker (18) speist. Der zweite 
Differenzverstärker (19) wird von einem weiteren Stromspiegel (14) 
gespeist, der mit einer Spannungsquelle (17) verbunden ist. Der Ausgang 
des zweiten Differenzverstärkers ist mit einer Stromsummenschaltung (34) 
über einen weiteren Stromspiegel (31) verbunden, so dass das 
Gleichspannungspotential am Ausgang unabhängig von der Signalamplitude 
bleibt. Die Schaltungsanordnung ist für niedrige Speisespannungen 
geeignet.

Patent EP-0426046-A3 (EP)
Title: Insectprotection-roller grill
IPC: E06B9/17
Filed: 1990-10-27
Abstract: The insect-protection roller grill includes a grating type insect protection grill, which is wound onto a winding shaft which can be arranged in a conventional roller shutter box. Fixed at the lower end of the insect-protection grill is a guide strip which is taken up in a lead weight strip. The guide strip extends beyond the weight strip at both axial ends and engages in side guide rails in which it is guided when the insect-protection grill is wound up and down. The weight of the lead strip causes smooth winding down of the insect-protection grill from the winding shaft when the latter is released. The weight strip is permanently tensioned in the wound-down state, so that it cannot be torn out of the side guide rails even by gusts of wind. The roller grill is economical to obtain and assemble, so simple to handle that it can be operated both by children and adults, and prevents the penetration of insects virtually completely, so that the use of "insecticides" in living areas can be avoided. <IMAGE>

Title: A surgically implantable device and stepping motor apparatus which may be used therein
Inventor: HAKIM SALOMON DR MED
IPC: A61B17/00
Filed: 1984-07-23
Abstract: The described surgically-implantable device has a stepping motor that can be isolated physically from electrical power sources and powered by the influence of a magnetic field applied from outside the body. The stepping motor includes a rotor and one or more stator elements, the stator elements being composed of magnetically soft and permeable material shaped and positioned with respect to the rotor so that when magnetized under the influence of the external field the stator elements strengthen and orient the magnetic field in their vicinities so as to cause movement of the rotor. The stepping motor may be used in a surgically-implantable shunt valve in which the popping pressure is adjusted in finite increments by application of the external magnetic field.

Patent EP-0402010-A3 (EP)
Title: Polarization retaining fiber optic coupler and method
IPC: G02B6/04
Filed: 1990-05-24
Abstract: To fabricate polarization retaining couplers, the fibers must be 
kept untwisted and must be maintained parallel to one another, and the 
major axes of the polavitation-retaining single mode (PRSM) (115,116) 
fibers must be maintained substantially parallel to one 
another. It is noted that this orientation includes that 
orientation wherein the major axes are substantially 
coaxial. The method of the present invention is 
characterized in that the fiber coating material is 
utilized to facilitate the alignment of the major axes of 
the fibers. In a first described embodiment, each fiber is 
provided with a rectangularly shaped coating (117,118), and the two 
larger flattened sides of the coating are specifically 
oriented with respect to the major and minor axes of the 
PRSM fiber therein. Cores (141) and (143) of 
optical fibers (115) and (116), respectively, are 
elliptically-shaped, and the minor axis of each core is 
parallel to the long flat sides of the rectangularly-shaped 
coating.  
     In one embodiment, tube (110) is heated and collapsed 
onto fibers (115) and (116) in a step that is separate from the 
step of stretching the midregion of tube (110). 
The flame from burner (129) is directed onto 
midregion (128) to heat glass tube (110) to its softening 
point. Burner (129) may remain stationary, or it may 
traverse midregion (128) in the direction toward vacuum 
source (126) as shown by arrow (130). It is an optional 
feature of the tube collapse step to apply a vacuum source 
to both hollow filaments (121) and (122), in which case the 
direction of burner traverse is immaterial. Midregion (128) 
becomes a solid region that is preferably free of air 
lines, bubbles, or the like.

Title: X-ray tube for ct apparatus
IPC: H01J35/24
Filed: 1991-04-30
Abstract: An X-ray tube for a CT apparatus comprises a ring-shaped 
vacuum tube (12) containing a fixed cathode (13) having a 
thermion emitting surface, a ring-shaped fixed anode, (15) 
and a ring-shaped rotatable cathode (14) interposed between 
the fixed cathode and fixed anode. The rotatable 
cathode defines a thermion receiving surface (49) opposed to 
the thermion emitting surface, and a thermion emitting 
portion (41) opposed to the fixed anode. Thermions are 
emitted from the thermion emitting portion toward the 
fixed anode while the rotatable cathode is suspended to 
non-contact state and rotated at high speed. With the 
thermions being accelerated and colliding on the fixed 
anode, an X-ray is generated toward the center of the 
vacuum tube. The X-ray generating position moves at 
high speed along a circumferential surface of the fixed 
anode with rotation of the rotatable cathode.

Title: Packet-at-a-time reporting in a data link controller.
Inventor: GULICK DALE E
IPC: G06F13/00
Filed: 1988-03-25
Abstract: A data link controller (DLC) 52 is disclosed which employs buffers (100,106) on both receive and transmit sides. These last-in, first-out buffers contain a position indicating that a character is the last one of a packet. In this way, a user need not monitor reception or transmission on a character-by-character basis, but need only concern themselves with packets. The receive and transmit FIFO's generate requests for more characters by monitoring the number of characters stored and thereby automatically receive and transmit characters without processor intervention. A four-stage mechanism (600,602,604,606,608,610,612,614) permits monitoring of multiple contiguous frames (back-to-back frames) received. Control of the DLC is provided by status and control registers (112,212) which are accessible to the user via a microprocessor interface (50). Particular registers have bit positions monitoring status conditons in such a manner that the most-probable one of a set of conditions compries the least-significant bit position, while the least-probable condition occupies the most-significant bit position. This affords simple shift and test technique for monitoring status conditions.
