Patent EP-0222076-A3 (EP)
Title: Method for transmitting speech and data
IPC: H04B7/26
Filed: 1986-08-14
Abstract: The method is intended to avoid the disadvantages of the known FDMA (frequency division multiple access) methods and TDMA (time division multiple access) methods. According to the invention, a narrow-band time division multiple access method (FD/TDMA) is used, that is to say a combined frequency division multiple access/time division multiple access method. Transmission preferably occurs in n radio channels with a transmission rate of m kilobit/s, in such a manner that the total transmission rate is r = m . n </= 100 ... 200 kbit/s. A multi-layered modulation is preferably used in such a manner that the transmission bandwidth is below the coherence bandwidth of about 250 kHz.

Abstract: A multi-dimensional comb filter system for processing 
e.g. a quadrature modulated color television signal includ­
es an input for receiving the signal; a first comb filter oper­
ating at the first period (such as the picture frame rate); and, 
a second comb filter operating at the second period (such 
as the picture line rate) connected in tandem with the first 
comb filter. A delay matching network is connected to the 
input and provides a delay to the original signal corre­
sponding to the sum of the first period and the second pe­
riod. A linear adder circuit is connected to the second comb 
filter ans to the delay matching network for combining in 
phase the delayed signal passing through the delay match­
ing network and the signal put out by the second comb filter. 
The adder circuit includes an output for putting out the sig­
nal which has been separated by multi-dimensional comb 
filtering of the original signal without any process adaptivity 
or switching in response to the content of the original signal.

Patent EP-0200355-A3 (EP)
IPC: H01L23/52
Filed: 1986-03-26
Abstract: In wafer-scale-integrated assemblies, microminiature 
transmission lines (40, 44, 46, 48) are utilized as interconnects on the wafer (42). The 
extremely small cross-sectional area of a typical such line results 
in its total line resistance being relatively large. Such a line 
exhibites signal reflections and resonances. In practice, it is not 
feasible to eliminate these effects by conventional load termination 
techniques. As a result, the frequency at which digital signals can 
be transmitted over such a line is typically limited to well below 
its so-called resonance limit. The invention enables the structural 
parameters of each line to be selected to meet specified design 
criteria that ensure optimal high-frequency performance of the 
line.

Abstract: A printhead (10) of a resistive ribbon printer has a column 
(15,16) of electrodes formed on each of at least two edge 
surfaces (17,18). When the column (15, 16) of electrodes at one edge 
surface (17, 18) is worn out after being used for printing, the 
printhead (10) is rotated so that the column (15, 16) of electrodes at 
the other edge surface (17, 18) is used for printing. Instead of the 
column (15, 16) of electrodes at each edge surface (17, 18) being the 
same size, the column (15, 16) of electrodes at one edge surface (17, 18) 
could be smaller than at the other edge surface (17, 18) so as to have a 
higher resolution for graphics whereby the position of the 
printhead is changed each time that higher resolution is 
desired and then returned to its initial position when 
alphanumeric printing is to occur. The printhead could have more than 
two edge surfaces (17, 18) with each having a column (15, 16) of 
electrodes for printing when at the printing position.

Filed: 1987-06-15
Abstract: In a process for the production of a 'water-in-fuel' or 
'melt-in-fuel' emulsion explosive a density-reducing 
agent is introduced and dispersed in the emulsion at an 
elevated temperature whereat the emulsion is essentially 
liquid, the explosive is cartridged and then subsequently 
cooled by means of a refrigerated fluid so that the 
continuous phase solidifies and stabilises the dispersion 
of the density-reducing agent in the explosive. Preferably, 
when the density-reducing agent comprises gas bubbles the 
explosive is subjected to an elevated pressure before it 
is cartridged in order to ensure that the sensitivity of 
the explosive will not be impaired by disturbance of gas 
bubbles by any pressure drop which might occur during 
cartridging.  
     The invention also extends to a cartridging machine for 
cartridging emulsion explosive, the machine comprising 
a container defining a sealed pressurizable explosives 
chamber which has an explosives inlet and at least one 
explosives outlet provided with a positive displacement 
pump for pumping explosive from the chamber into a 
cartridge.

Abstract: A relational database (159) is created and queried through the 
use of an outliner-style text editor (141) which permits automatic 
generation (161) of data entry forms (151) for the creation of records 
(149b). Data entry (157) and editing are simplified and errors are 
minimized because changes (142) in the outline (141) are automatically 
reflected in the data entry forms (151) and thus the automatically 
updated records (149b). Data retrieval is driven through the 
manipulation (142) of the outline (141) to allow simple and complex 
queries without utilizing a database programming language. 
The query mode features a continually displayed 
outline (440) in an Outline Window (437). Criteria are specified in a 
Criteria Window (430) in which one or more fields are assigned 
specific search values. Records matching the criteria are 
displayed in a Response Window (438). For an outline-wide word 
occurrence search, areas of the outline which include an 
occurrence of the word are highlighted.

Title: Intramedullary anchorage nail
IPC: A61B17/58
Filed: 1988-08-05
Abstract: An intramedullary anchorage nail for the treatment of fractures in long tubular bones consists of a hollow body (1) of histocompatible metal and a similarly histocompatible non-metallic inner body (2a, 2b) whose material has a lower resistance to deformation than has that of the hollow body (1). The inner body (2a, 2b) lies secure against twisting in the hollow body (1). The hollow body (1) and the inner body (2a, 2b) have mutually complementary holes (12 to 15, 17, 18). So that reductions in the cross-section of the hollow body (1), which may occur when driving the hollow body (1) into the medullary cavity of a bone, do not too greatly impede the insertion of the inner body (2a, 2b), it is proposed that the inner body (2a, 2b) consist of two partial bodies (2a, 2b) whose longitudinal extent is as great as is necessary for the retention of screws introduced into their holes (14, 15, 18). <IMAGE>

Abstract: A level shift circuit is made up of a capacitor 
(19), a MOS inverter (20), and a bias circuit (R5) for 
applying a bias voltage to an input node of the MOS 
inverter (20). A first electrode of the capacitor (19) 
is connected to an output stage of an ECL circuit (13), 
while a second electrode to the input node of the MOS 
inverter (20). The output node of the MOS inverter (20) 
is coupled with an input stage of a CMOS circuit (16). 
An output signal of the ECL circuit (13) is capacitively 
coupled with the input node of the MOS inverter (20) so 
that it is superposed onto a bias voltage being supplied 
from the bias circuit (R5). A level of this signal is 
shifted to a CMOS logic level by the MOS inverter (20), 
and then applied to the input stage of the CMOS circuit 
(16).

IPC: F16F9/49
Filed: 1985-08-19
Abstract: Landing gear mechanism includes a built-in hydraulic actuator 
(30) which may be actuated to provide a heavy load range, soft spring rate 
during take-off with a heavy take-off weight and a lower load range, softer 
spring rate after take-off and prior to landing with a lighter landing weight 
to yield more shock strut stroke for a given range of vertical load during 
landing. A special taxi valve (45) allows for some fluid to bypass the main 
orifice (15) more freely to and from the lower piston damping chamber (54) 
to the shock strut air-oil chamber (20) as soon as the landing energy stroke 
is complete to greatly reduce or eliminate high damping loads that might 
otherwise take place as the gear negotiates bumps. Such a valve may 
automatically be set to close for landing by the action of the gear extension 
during a subsequent take-off, thus reactivating the main orifice. For normal 
bounce, air in the primary chamber (20) drives oil through an orifice (69) in a 
rebound damper valve (65) to the lower piston chamber (54) in order to lift 
the supported weight of the aircraft as part of the return stroke. However, 
when riding over a hole, the air acts freely on the differential or net piston 
area of the gear which is too small to lift the supported weight of the 
aircraft, but is large enough to accelerate the unsprung mass of the gear 
quickly into the hole. An anti-cavitation bypass valve (62) assures oil refill 
in the lower portion of the piston chamber as the gear extends. Also, a 
pressure actuated valve (71) may be provided in the metering pin (10) which, 
upon sensing cavitation in the lower piston chamber (54) during extension, 
will open a series of holes (72, 73) both above and below the main orifice 
(15), providing a flow path for oil around the main orifice, to eliminate the 
aforementioned cavitation. The metering pin is part of this flow path. A 
check valve (95) may be provided at the top of the metering pin to keep the 
metering pin full of oil by allowing free flow of oil upward but not allowing 
downward flow, thus preventing the intake and down flow of shock strut air 
during the anti-cavitation re-fill of the lower piston chamber. An extension 
snubber valve (116) may also be provided to develop piston rebound damping 
during the last portion of stroke of the landing gear before full extension 
thereof during take-off.

Abstract: A television receiver has equipment to provide a normal aspect-ratio display from a wide aspect-ratio format signal as broadcast. With the pan vector A set to the start of the store, the signal is read into line stores RA, GA, BA using clock 1 while line stores RG, GB, BB are being read using pan vector B as start address and clock 3 as the output clock. Clock 2 is selected as an output clock if the aspect-ratio information does not indicate a wide aspect-ratio transmission. The line stores are switched at half line rate so that stores RA, GA, BA are now read out, while RB, GB, BB are rewritten. Pan vector is now set to the start of the RAM/FIFO of the line start and pan vector A is set for the start of the expansion period. The sequence is again switched back on following alternate lines.
Patent EP-0299807-A3 (EP)
IPC: H02P9/14
Filed: 1988-07-18
Abstract: The improved engine load management system of the present 
invention includes an apparatus that will de-excite the field 
coils of an alternator that is driven by an internal 
combustion engine when the battery that the alternator charges 
is above a required minimum voltage and when the engine is 
operating under high load conditions such as acceleration or 
climbing. When the battery charge falls below the required 
minimum, the apparatus excites the alternator field coils and 
permits the alternator to charge the battery despite a high 
engine load condition. When the battery charge is above the 
minimum required voltage, but below the voltage at which 
charging is discontinued, and the engine is under high load, 
the alternator field coils are energized and de-energized in a 
cycle that reduces alternator drag on the engine, but permits 
 
 
limited battery charging to occur. The limited charging rate 
is greater as the battery voltage is lower, and the change 
from lesser battery charging to greater battery charging is 
linear and inversely related to the charge of the battery. 
When the engine is operating at normal load conditions, such 
as cruise, battery charging is accomplished on demand under 
normal circumstances. Deferring battery charging by limiting 
alternator field coil excitation, reducing alternator drag on 
the engine during heavy load conditions (an inherently 
inefficient operating regime for internal combustion engines) 
increases fuel economy and decreases atmospheric pollutants 
from automobiles equipped with the apparatus of the current 
invention.
