Title: Continuously transmitting and receiving radar
IPC: G01S13/32
Filed: 1989-12-01
Abstract: A CW radar comprises a substantially continously operable 
transmitter (10) and receiver (16,18,20), signal operating means 
(12,14) for radiating the transmitter signal and for receiving at 
least the return signal and a reflected power canceller (RPC) 
circuit (26, 28 and 30) for cancelling leakage signals in a 
signal path from the signal operating means to the receiver. The 
receiver front end comprises quadrature related mixers (18,20) 
which supply intermediate frequency signals (I₁ and Q₁) to a low 
frequency control loop (32, 34, 36) which supplies at least a 
pair of control signals (I c ,Q c ) to a four quadrant vector 
modulator (28) in the RPC circuit. In order to be able to 
optimise the cancellation of phase as well as amplitude, the 
control circuit loop includes means for synthesising control 
vectors (I₁, -I₁, Q₁ and -Q₁) from the outputs of the quadrature 
related mixers (18,20). Selecting means selects a pair of 
quadrature related control vectors from those control 
vectors synthesised on the basis of minimising leakage in the 
outputs of the quadrature related mixers (18,20). The selected 
control vectors (I c ,Q c ) are applied to the four quadrant vector 
modulator (28) which preferably comprises a pair of analogue 
driven biphase modulators (56,58 - Figure 4 (not shown)). In an 
alternative embodiment (Figure 7) the four quadrant vector 
modulator comprises four voltage controlled attenuators to which 
respective control vectors (I c , -I c , Q c  and -Q c ).

Title: Method and device for engaging the yarn with and joining it to the silver in a ring spinning machine
IPC: D01H15/013
Filed: 1989-12-07
Abstract: The present invention relates to a method for automatically 
bringing yarn which has broken in a spindle of a ring spinning 
machine into engagement with and rejoining it to the textile fibre 
sliver passing through the last pair of drafting rollers (2,3), and a 
device for implementing the method.  
     With the method of the present invention the yarn end from the 
package is made to engage the textile fibre and passing through 
the last pair of drafting rollers, by the action of a mobile arm (1) 
the terminal part of which comprises a scissor element overlying a 
gripper element (9), said mobile arm guiding the yarn end into a 
position resting against the side of the presser roller, which 
then drags said yarn end round until it is trapped below the line 
of contact between the presser roller (2) and the drafting roller (3), to 
enable the yarn to be engaged with the textile fibre sliver (10) and 
thus effect the rejoining of the yarn to the sliver.

Title: Method of strengthening metal material and apparatus therefor
IPC: C22F1/00
Filed: 1989-03-22
Abstract: A method of strengthening a metal material of a cast 
product consisting of a unidirectionally solidified structure 
of crystals extending long in a direction of casting, and an 
apparatus for realizing this method. The cast product (12) is 
passed through a zigzag path formed by contact with circumfer­
ential surfaces of rotatable rolls (16, 18, 22, 26, 28, 31), 
so that repeatedly bending deformation is applied to the cast 
product to thereby harden the cast product. The repeatedly 
bending deformation grows dislocation in crystals of the cast 
product competitively, so that free movement in dislocation of 
crystals cannot be made any more. As a result of the growth 
competition of crystals, a strengthened metal material is 
obtained.

Title: Non-crosslinked crystallized polymer coatings
IPC: A61L31/10
Filed: 1989-11-08
Abstract: A non-crosslinked crystallized polymer or polymer 
blend coating is disclosed for articles that come into 
contact with bodily fluids. The polymer or polymer blend 
to be used is crystallizable and is stable in the presence 
of water at temperatures of up to about 60°C. when in the 
crystalline state. The polymer or polymer blend is 
dissolved in a solvent, such as water or dimethyl sulfoxide

is then crystallized, generally by heat treatment, 
providing both toughness and increased adherence of the 
coating to the article without ready dissolution when the 
article comes into contact with fluids.

Title: Kernel testing interface and method for automating diagnostics of microprocessor-based systems
IPC: G06F13/38
Filed: 1989-11-22
Abstract: An improved testing apparatus and method for 
testing the kernel of a microprocessor based unit under 
test (UUT) where connection to the UUT is made at both 
the memory connection socket and at the microprocessor 
with the microprocessor being in place and active in 
the UUT. The apparatus and method permits subtantially 
full diagnostics of the kernel to be carried out in a 
systematic and automated manner in which the 
requirement of manual probing of the UUT is minimized. 
Connections at the microprocessor permit the 
development of high resolution sync signals for 
verification and evaluation of test results and permit 
testing without latching of signals on the data bus. 
The testing protocol implemented in the methodincludes 
the use of testing primitives which permit the 
development of a signature for each address and data 
bus line for the identification of the type as well as 
the location of any faults discovered by the apparatus. 
The method of testing exploits bootstrapping techniques 
including three primitives for bus test, data stimulus 
and address stimulus to optimize simultaneous testing 
and circuit fault diagnosis.

Title: Absorbent mixture, method of making same, and absorbent article including same
IPC: D06M101/34
Filed: 1990-05-17
Abstract: An absorbent mixture, as made from fibers 
formed into a fibrous web and a polymerizable, 
cross-linkable material, in a liquid carrier. The 
material, when polymerized and cross-linked, results 
in a superabsorbent polymer. The material, in the 
liquid carrier, is dispersed within the fibrous web,

cross-linked in situ, within the fibrous web, so as 
to form a composite web comprising the fibrous web 
and the superabsorbent polymer, as dispersed 
particles, at least some of which are bound to fibers 
from the fibrous web. The composite web is ground, 
so as to cause some of the superabsorbent polymers to 
become particulate while fragments of the 
superabsorbent polymer remain bound to fibers from 
the fibrous web. Before the composite web is ground, 
it may be provided with a fibrous layer or fibrous 
layers in intimate contact therewith, and also 
compressed.

Title: Circuit for analogic terminal telephone sets connected to a digital line
IPC: H04M19/02
Filed: 1991-05-03
Abstract: 2.1 The power required for the operation of telephone terminal sets fed remotely via the digital connection line is to be adjusted in such a way that power distribution is implemented in operational instances of high power demand. The feed range of the digital connection line is to be increased as a result. 2.2 An energy store provided for ringing current generation is charged via a constant current source in such a way that the power required to call a plurality of subscriber terminals is available. The constant current source is switched to a lower current value if the occupancy state is identified on at least one of the subscriber terminals, so that fewer subscriber terminals can switch to the ringing state. When ringing states occur simultaneously, the ringing transmission is performed in a plurality of phases. 2.3 The circuit arrangement enables load distribution, by means of which the current flowing via the digital connection line is reduced so that the feed range is substantially increased. <IMAGE>
