Patent EP-0247749-A3 (EP)
IPC: H03B5/18
Filed: 1987-05-07
Abstract: A push-push broadband dielectric resonator 
oscillator circuit 10 that operates in the K and Ka band 
frequency range has two oscillator circuits 1 and 
3 that oscillate at the same fundamental frequency. An 
antiphasel relationship is maintained between the two 
oscillators through the use of a dielectric resonator 5 
and the desired frequency is obtained by vectorially 
combining the output signals of the two oscillators 
1 and 3 that have the antiphase relationship to obtain an 
output frequency that is twice the fundamental frequency 
of operation of each of the individual dielectric 
resonator oscillator circuits.
Patent EP-0247812-A3 (EP)
IPC: B29D23/00
Filed: 1987-05-22
Abstract: There is disclosed a method of making a hose 
comprising the steps of extruding a tube (10) having 
inner (13) and outer (12) covering of rubber on a woven 
jacket (11), inserting the tube (10) into a sheath (15) 
having a larger diameter than the tube, curing the tube 
(10) which expands radially during said curing so that 
the outer covering (12) is urged into tight engagement 
with the sheath. The sheath prevents further radial 
expansion of the tube and the outer covering (12) is thus 
embossed with the surface topography of the inner 
surface of the sheath upon removal of the sheath. The 
hose thus formed has good diametral swell properties.  
     The hose may also be formed with perforations in 
the inner covering (13) and offset perforations in the 
outer covering (12) which perforations terminate at the 
jacket (11) and allow water in the hose to percolate.

Title: Part program generating system
IPC: G05B19/4097
Filed: 1989-03-10
Abstract: The present invention is a system that takes a 
drawing definition produced by a CAD/CAM system 10 and 
produces a debugged program to machine apart by numerical 
control. The drawing definition is a list of the surfaces 
which create the part. A list of surface features from a 
drawing is scanned by a process planner 14 and a list of 
primitive shapes and transition points in each shape is 
created to produce a process tree which controls regions 
for machining. The process also specifies tools, feeds 
and speeds necessary for rough machining the part. An 
appropriate machine is selected based first on the rough 
stock dimensions of the stock to be used to make the part 
and then on the number of tools that can be held by the 
machine and possible feed speeds of the machine. A code 
generator 16 completes macrocalls corresponding to 
processes required to make the part. The resulting part 
program is transferred to a code processor 18 which 
produces the machine tool code for the particular machine 
20 selected.

Title: Parameter value communication system
IPC: H04Q9/00
Filed: 1989-11-29
Abstract: A multipoint communications system for transmitting the 
values of a multiplicity of analog parameters from one point 
digitally to another point and reconverting then into analog 
parameters. The system includes a plurality of input modules 
which communicate with respective output modules over a 
communications link. The input and output modules are configured 
similarly with a control processor connected to either 
multiplexing circuitry, in the case of an input module, or 
demultiplexing circuitry in the case of an output module. The 
multiplexing circuitry is connected to a plurality of 
configurable input circuits which receive the values of the 
various measured conditions or parameters. The demultiplexing 
circuitry is connected to a plurality of configurable output 
circuits which output the values of the various measured 
conditions or parameters. In a preferred protocol, a link master 
is chosen from among the input modules to generate a polling 
sequence for the input-output module pairs. A poll of a 
particular module is taken by generating a wake-up message, which 
the module responds to with a ready message. When a ready 
message is received, the link master generates a go-ahead signal 
and becomes dormant for a time period before continuing. 
 
 
Otherwise, if a ready message is not received, the poll will 
continue. When a module has authority to communicate, it wakes-­
up its corresponding output module, which responds with a ready 
message. When the selected input module receives a ready 
message, it transmits a plurality of stored digital values 
corresponding to the analog parameters which were input. The 
system includes a communications mode where the values are 
transmitted, a calibration mode where the range of input and 
output values are set for each module, a configuration mode where 
each module is assigned an address and each input and output 
matched and configured. An input can be configured for voltage, 
current, TTL, or contact closure inputs and an output configured 
to output voltage, current, TTL, or contact closure.

Title: Furniture lock system with interchangeable cylinder locks
IPC: E05B9/08
Filed: 1989-08-08
Abstract: The lock system has a guide bush (3) which can receive a lock cylinder (4) with a cylinder housing (5) and cylinder core (7). Arranged in a recess (10) of the cylinder housing (5) is a blocking element (11) which can snap into a recess (12) of the guide sleeve (3). To exchange the lock cylinder (4), a passage (18) in the cylinder core (7) and a passage (19) in the cylinder housing (5) are brought into coincidence, and the blocking element (11) is deflected towards the cylinder core (7) by means of a pin (15) inserted through these passages (18, 19). An actuating part (14) thereby penetrates into a recess (17) of the cylinder core (7). This recess (17) extends only over a small part of the circumference of the cylinder core (7), so that outside the exchange position the blocking element (11) cannot be deflected even when the collar (9) is drilled through. <IMAGE>

Title: Method and combustion installation for the reduction of nitrogen oxide formation during the combustion of fossil fuels
IPC: F23C9/08
Filed: 1990-02-14
Abstract: In the method for reducing the nitrogen oxide formation in the combustion of fossil fuels in a combustion chamber, flue gases are, after preceding removal of heat, recycled to the burner side of the combustion chamber and, due to the injector action of the flame, introduced around the burner into the combustion space in a part quantity reducing the combustion temperature to a temperature level which is at most equal to the limiting temperature for the formation of nitrogen oxides. As a result, the flame is surrounded by  - cool - flue gases and cooled. In a firing installation, a combustion chamber arranged within a housing carrying a flow of a heat carrier medium has a "hot" combustion space which is surrounded by a shell accommodated at a distance from the combustion chamber walls. Flue gas flow paths extend between the shell and the combustion chamber, and at least one inflow path branches off from these for recycling a part stream of the - cooled - flue gas into the combustion space, this path leading into the latter in the vicinity of a burner or flame tube and cooling the combustion flame. <IMAGE>

Title: Echo canceller having fir and iir filters for cancelling long tail echoes
IPC: H04B3/23
Filed: 1990-02-23
Abstract: An echo canceller comprises a finite impulse response filter (6) 
connected to the incoming port of a hybrid (1), and a tail canceller (7) 
which includes an infinite impulse response filter (24; 40) having a 
multiplier (14; 33) for recursively multiplying an output digital symbol 
from the tapped-delay line (8) of the FIR filter with an attenuation 
coefficient R. A digital symbol from the IIR filter or one from the tapped-­
delay line (8) is multiplied with a tap-weight coefficient C i  and summed 
with the outputs of tap-weight multipliers of the FIR filter to produce a 
replica of an echo symbol, which is subtracted from a digital symbol y n  
from the outgoing port of the hybrid (1), producing a residual echo 
symbol e n . The coefficient C i  is derived from correlation between 
residual echo e n  and a symbol from the tapped-delay line. In one 
embodiment, symbol from the tapped-delay line is further delayed (17) 
for a unit interval on the one hand, and multiplied (18) with coefficient R 
on the other, the difference between them being detected (19) and 
multiplied (20) with a coefficient K, which is either sgn(C i ) or 1/C i , to 
generate a multiplied difference. Correlation is detected (22) between the 
difference and residual echo e n  to derive the coefficient R. In a second 
embodiment, symbol from the tapped-delay line is further delayed (36) 
for a unit interval and multiplied (37) with K to produce a delayed-­
multiplied symbol. Correlation is detected (35) between it and residual 
echo e n  to derive the coefficient R.
