Patent EP-0250832-A3 (EP)
Title: Cavity-backed  slot antenna
IPC: H01Q13/18
Filed: 1987-05-20
Abstract: An electrically-small, cavity-backed slot antenna includes an 
electrically conductive sheet (44) having 
an elongated slot (20) contained 
within the perimeter of the sheet backed by a cavity (32) formed in an 
electrically conductive housing connected to the sheet. A dielec­
tric layer (16) composed of material having a dielectric constant of 
ten or greater is coupled to the conductive sheet and overlies 
the slot so as to effect a reduction of the resonant frequency of 
the antenna which permits the antenna to be characterized as 
electrically small. Transmission conductors (24) are electrically 
coupled to the conductive sheet across the slot and adapted to 
carry r.f. energy either to or from the sheet depending upon 
whether the antenna is being used in a transmit or receive mode. 
For fine tuning the resonant frequency of the antenna, a pair of 
capacitive elements (22) are mounted across the slot and electrically 
coupled to the conductive sheet on opposite sides of the slot and 
at symmetrical locations therealong. The elongated slot con­
tained within the perimeter of the conductive sheet can have a 
configuration in the shape of either a straight line or an uncon­
nected square, circle or triangle.
Patent EP-0248437-A3 (EP)
IPC: C08J3/24
Filed: 1987-06-04
Abstract: A process for improving a water absorbent polyacrylic 
acid polymer in which the polymer is contacted with an 
aqueous solution containing a water soluble peroxide 
radical initiator, followed by heating, thereby causing 
substantially only the surface portion of the polymer to 
undergo crosslinking with the radical initiator while 
leaving the remaining core portion of the polymer substan­
tially intact. The improved water absorbent polyacrylic 
acid polymer is excellent in both water absorbency and 
water absorption rate, and the hydrogel resulting from 
absorption of water has a pleasant, non-sticky feel. The 
improved water absorbent polyacrylic acid polymer can be 
advantageously utilized to produce a desirable disposable 
diaper, sanitary napkin, surgical pad, surgical sheet, 
paper towel or the like.

Title: On-chip on-line ac and dc clock tree error detection system
IPC: G06F11/22
Filed: 1988-01-15
Abstract: A test circuit for producing a "fail" signal if a clock path driver circuit develops an AC or DC defect. In the simplest embodiment, this test circuit comprises a time delay block for providing a delayed clock signal and its complement, with a delay that exceeds the signal propagation time through the clock receiver and driver; a latch which, in one embodiment, is clocked by the complement of the delayed clock signal to receive the drive signal and to generate pulses which do not overlap in time with the pulses of the delayed clock signal during normal circuit operation; and a gate for detecting such a pulse overlap and for generating an error signal to indicate an AC or DC fault. This circuit effectively detects AC faults at one edge of the clock pulse and one type of DC fault. In a further embodiment of the present invention, this circuit can be combined with a complementary circuit to detect AC faults at both edges of the clock pulse. In a preferred embodiment, the present test circuit is used with a plurality clock trees on a chip, and all of the error signals from these test circuits are combined to form a single chip error signal.

Title: Method for continuous preparation of highly pure monoglyceride
IPC: C12P7/64
Filed: 1988-05-27
Abstract: A method for continuous preparation of highly pure monoglyceride comprises the steps of esterifying fatty acid dissolved in a nonpolar solvent at the interface between the nonpolar solvent phase and a polar solvent phase containing glycerol, water and dispersed lipase, the polar phase being located below the nonpolar phase, continuously taking out the nonpolar solvent phase, cooling the taken out phase to isolate the resulting monoglyceride by precipitation, and bringing back the remaining solution to the esterification system. By this method, monoglycerides having high purity can be produced continuously and at low cost, and further monoglycerides of straight-chained fatty acids can preferentially obtained even though the fatty acids used contain branched fatty acids.
Patent EP-0294757-A3 (EP)
Title: Process of preparing higher order cuprate complexes
IPC: C07F1/08
Filed: 1988-06-07
Abstract: This invention encompasses a process for preparing higher order cuprate complexes which contain a carbanion for the formation of carbon to carbon bonds in reactions such as 1,4-conjugate addition. The complex is formed by reacting a first cuprate complex with a stannane such that the carbanion to be used to form carbon to carbon bonds is transferred from the stannane to the first cuprate complex to form a different higher order cuprate complex. This process permits the in situ preparation of a higher order cuprate complex having the carbanion desired to be used in a synthetic reaction. Higher order cuprate complexes prepared by this process are particularly useful for the efficient preparation of pharmacologically active prostaglandins.

Patent EP-0304194-A3 (EP)
Title: Data carriers
IPC: G06K19/06
Filed: 1988-08-03
Abstract: A carrier (1,101) bears data in the form of one or more 
holographic optical elements (HOEs) (4,104) representing 
e.g. identification data on an access-control card or 
authentication data for documents or goods. In Fig 1, 
each HOE (4) is adapted to couple into the structure of 
the carrier light directed at a selected angle from an 
emitter (9) in a reading apparatus and to direct that 
light within the carrier at an angle such that it is 
transmitted through the carrier by a process involving 
total internal reflection at an exposed surface thereof. 
The light can therefore be coupled out of the carrier at a 
location spaced from the HOE (4) through an element (11) 
of selected refractive index placed into contact with the 
surface of the carrier, and sensed by an associated 
detector (12). Alternatively in Fig 7 there is a light 
path from an emitter (110) coupling light into the carrier 
through an element (111) of selected refractive index, 
with the light being transmitted by total internal 
reflection to a HOE (104) which couples it out to a 
detector (112). In either case, detection of light from 
one location on the carrier when it is illuminated at 
another location therefore signals the presence of the HOE 
(4,104) which otherwise remains completely invisible. 
The presence or absence of HOEs at specified positions 
along a track or in other forms of array can therefore be 
used to represent data bits, to be detected along parallel 
tracks or at different array positions by virtue of the 
light transmission through the carrier, making fraudulent 
reproduction or imitation of the data very difficult.
