Patent EP-0266484-A3 (EP)
IPC: F21S8/00
Filed: 1987-05-19
Abstract: The present invention provides a light display system 
for projecting a double-pattern light display. A luminaire 
holding the lamp and light control devices is fixed to a 
first housing (12) that in turn is nonrotatably mounted mounted 
to a control bar (24). A second housing (14) containing a fixed 
reflector apparatus (70-72) adapted to receive the light beam from 
the luminaire is connected to and rotatable relative to the 
first housing (12) about a first axis (16). The second housing (14) 
contains a reflector (76) rotatable about a second axis. The 
rotatable reflector (76) receives the light beam from the fixed 
reflector apparatus (70-72) and projects the beam in a geometric 
configuration, preferably a vertical plane that contains the 
first axis (16). A pan driver attached to the first housing 
rotates the second housing (14) about the first axis (16) by way of a 
gear and belt mechanism that is connected to a cylindrical 
mounting member attached to the second housing (14). The 
stationary luminaire (18) directs the light beam through a 
cylindrical passage in the cylindrical mounting member. A 
tilt driver attached to the second housing (14) rotates the 
rotatable mirror (76) about the second axis, which is 
perpendicular to the first axis (16). A slip-ring connector 
connected to the cylindrical mounting member transmits 
electrical power from the power source to tilt driver. The 
light beam is thus moved simultaneously about two axes so as 
to cast a double patterned light on the environment.

due to temperature changes. An extension rod (8) is 
secured to the piston (6) which slides together with the 
piston (6). Spring means (10) between relative slide 
members within the barrel (2) act to cancel the starting 
frictional force created on the sliding faces.
Patent EP-0261049-A3 (EP)
IPC: D04B15/90
Filed: 1987-09-17
Abstract: The invention refers to the stretching means (4, 5) used in 
rectilineal knitting machines, and is centered in the 
fact that such means adopt a modular configuration along 
the machine, in a way that each of said modules has an 
independent actuation.  
     In this way, by means of the active participation of 
a variable number of such modules, the adequate stret­
ching level at each moment is attained, that is, a chan­
ging or variable stretching, especially ideal for the 
modern structures of the knitting and for the new types 
of fibers used to that purpose.  
     Specifically, the invention sets forth the use of a 
fixed axle, on which it is established a plurality of 
stators corresponding to respective electromotors, in 
each of which the rotor houses said stator and is rec­
overed at the same time by a layer of rubber or synthe­
tic rubber, through which said rotor actuates on the fa­
bric to attain the expected stretching.

The storage racks (1) have an interlocking design and can in each case be moved along two pairs of rails (11) of different gauge by means of geared motors (12) on their running wheels (9, 10), so that each container (2) can be made available for access by a hoist without restacking. <IMAGE>
Patent EP-0291761-A3 (EP)
IPC: C08G63/08
Filed: 1988-05-04
Abstract: Preparation of a macromolecular monomer of a lactone 
allows the preparation of copolymers of lactones with 
commonly available olefinically unsaturated monomers. 
There is no known method for the preparation of such 
copolymers. A cationic ring-opening polymerization of a 
lactone in conjunction with an unsaturated alcohol (propa­
gator) having an acryloyl, allyl or styryl double bond, 
produces a polylactone macromer having an ethylenic double 
bond at one end and a hydroxyl group at the other. The 
polymerization proceeds by polyaddition of the lactone to 
the OH group which is the propagating species. The poly­
lactone may include a polymeric or non-polymeric spacer. 
The propagator is a primary or secondary alcohol which, if 
cyclic may have a single internal double bond in one ring. 
The catalyst is an oxonium salt, or etherate of boron 
trifluoride. The macromer may be copolymerized with a wide 
variety of olefinically unsaturated monomers to form a 
macromer copolymer with pendant polylactone chains. In 
particular, block copolymers of terminally unsaturated 
macromers of ether-ester, or ester-ether structure may be 
tailored for specific applications.

Title: Animal derived cell with antigenic protein introduced therein
IPC: A61P43/00
Filed: 1988-06-14
Abstract: Animal derived cells, especially erythrocytes, have been artificially modified (and referred to as engineered erythrocytes or RBCs) so as to incorporate in their plasma membranes an antigen, CD4 protein derived from lymphocytes, which will cause them to selectively seek out and fuse with other cells that are infected with a virus, especially the AIDS virus. These modified cells can be further altered so as to contain in their cytoplasm a cytotoxic agent which, after the cell has fused with a target cell, will result in the pooling of their respective cytoplasms and the death of both cells, with subsequent removal by the reticuloendothelial system. The invention also includes the production and use of similarly modified liposomes. The present invention can be used as a treatment of Acquired Immune Deficiency Syndrome (AIDS).

Title: Method for fetching potentially dirty data in multiprocessor systems
IPC: G06F12/08
Filed: 1989-10-16
Abstract: A Fetch-Then-Confirm (FTC) policy is used for the 
handling of data fetch upon XIEX'S in a tightly 
coupled multiprocessor environment. The fetch and use 
of a requested data line upon XIEX is allowed before 
the SCE receives the confirmation of validity (or 
invalidity) of the requested line through the clearing 
procedure. Whenever a line having uncertain validity 
is used by a CP the results of execution of 
instructions depending on the validity of the line 
should not be committed to the cache until a 
confirmation is received from the SCE. When the 
confirmation from the SCE indicates that a line 
 L  is known to be valid, all results depending on the 
validity of  L  can be processed as usual. If, however, 
the SCE indicates that a previously fetched line 
 L  having uncertain validity is in fact invalid, all 
operations performed based on  L 's contents should be 
aborted and restarted properly when a valid copy of 
 L  is received.

Title: Improved screwdriver bit for phillips-head fasteners
IPC: B25B15/00
Filed: 1989-11-03
Abstract: A modified Phillips-type screwdriver bit is disclosed that 
is fully compatible with a standard Phillips-head fastener, and is 
designed to significantly increase the level of torque that can be 
applied to the fastener while at the same time substantially reducing 
the cam-out forces normally produced by a standard Phillips 
screwdriver bit. These results are accomplished by forming generated 
surfaces along the side walls of the bit wings so that the included 
angle defined by the converging side walls of adjoining bit wings 
gradually increases from the Phillips standard 92 degrees at the base 
of the bit wings to approximately 105 degrees at the wing tips. This 
configuration serves to confine the application of torque to the side 
surfaces of the bit wings initially along contact lines adjacent and 
parallel to the roots of the bit wings with the contact area gradually 
progressing radially outwardly as torque levels increase and the 
opposing side surfaces of the recess wings in the head of the fastener 
begin to deform.
