Patent EP-0248386-A3 (EP)
IPC: H01M4/96
Filed: 1987-06-01
Abstract: Discontinuities, edge sites and grain boundaries in carbons, 
the primary locations of instabilities for oxidative corrosion 
and degradation, are prepared by preoxidation to form carbon-­
oxides followed by highly selective and relatively mild 
fluorination to specifically substitute carbon - oxygen 
functionality with stable carbon-fluorine groups. The novel 
fluorinated carbons have enhanced chemical and/or electrochemical 
stabilities to corrosion, improved hydrophobicity, lubricating 
properties, etc.

Patent EP-0263472-A3 (EP)
Title: Apparatus for converting digital values to analog values
IPC: H03M1/00
Filed: 1987-10-05
Abstract: A plurality of members, each constructed to produce a 
sunstantially constant current when energized, are disposed 
electrically in a matrix defined by a plurality of rows and a 
plurality of columns. A plurality of signals cumulatively 
represent a digital value. Each of the signals has logic levels 
respectively coding for a binary "1" and a binary "0" and each 
has an individual binary significance. The binary signals of 
intermediate binary significance are decoded to activate an 
individual one of the rows. The binary signals of high binary 
significance are decoded to activate an individual one of the 
columns. The member common to the activated row and the 
activated column then receives a substantially constant current, 
as do all of the members of lower binary significance than such 
common member. The signals of lowest binary significance are 
also decoded to produce a current having a magnitude indicative 
of the binary value coded by such signals. This magnitude 
corresponds to that obtained by multiplying a particular portion 
of the substantially constant current by a ratio having a 
numerator the value represented by the binary signals of least 
binary significance and having as its denominator the maximum 
value capable of being coded by such binary signals. The 
current coding for the binary signals of least binary 
significance passes through a member otherwise superfluous in 
the matrix and preferably having an extreme position 
electrically in the matrix. The currents flowing through all of 
the members in the matrix are added in an output line to 
indicate an analog of the digital value.

Title: Commodity metering systems
IPC: G07F7/08
Filed: 1987-06-16
Abstract: A multi-rate commodity metering system comprises an electronic key containing an EEPROM, and a meter for metering the commodity and having a receptacle for receiving the key. The meter also contains a real-time clock. The key can operate as a programming device and a meter-reading device. When the key is initially inserted into the meter, it starts a billing period, eg a quarter, and if necessary programs the meter with the times for switching between rates and the prices per unit of the commodity for each rate. Towards the end of the billing period, the meter reading is entered into the key with the time and date to which it relates and a visible and/or audible warning is produced to remind the customer to remove the key and take it to the commodity supplier's premises so that the supplier can read out the meter reading from the key. If the customer fails to do this within a certain time, the supply of the commodity is cut off, although an emergency supply can be obtained for a further predetermined time if necessary.

Patent EP-0322207-A3 (EP)
Title: Recovery of non-ferrous metals from dross
IPC: C22B7/04
Filed: 1988-12-21
Abstract: The invention relates to a method and apparatus for treating non-ferrous metal drosses in order to recover the free metal contained therein. The dross is heated by a plasma torch (40) in a rotary furnace (10), preferably to a temperature above 800 DEG C. The plasma heating and rotary motion make it possible to recover metal from the dross without employing the conventional salt bath. This means that the gases exiting the furnace can be treated more easily to remove pollutants and the solid residues can be discarded without risk of causing environmental pollution. By controlling the speed of rotation of the furnace (10), large dross lumps can be accommodated and so the conventional grinding and screening procedure of the dross can advantageously be eliminated.

Title: Charge trapping correction in photon detector systems
IPC: G01T1/24
Filed: 1989-11-03
Abstract: In an energy spectroscopy system in which the photon 
detector (1) such as a germanium detector provides pulses 
indicative of incident gamma or x-ray radiation, 
compensation circuitry corrects the amplified pulse output 
for charge trapping effects in the detector. The 
compensated output is provided to a prior art multichannel 
analyzer (2). The compensation circuit (4) adds to the detected 
pulse a correction factor proportional to a polynomial 
function of charge collection time of the carrier being 
trapped multiplied by the amplitude of the pulse. In this 
manner, the output pulse is increased to compensate for 
impediments to charged carrier migration within the 
structure of the detector, and resolution is improved.

Title: Digital printers
IPC: H04N1/23
Filed: 1989-12-21
Abstract: An arithmetic frequency synthesizer (24) for generating a bit clock frequency for the flying 
spot scanner of a digital printer includes means for loading a pseudo-random offset value, 
accm i , into its accumulator at the start of each scan. The offset values for successive scans 
pseudo-randomly vary within a range 0 ≦ accm i  < N for all bit clock frequencies required 
for normal operation of the printer. Thus, the offsets psuedo-randomly phase shift the 
phase transitions of the bit clock sufficiently to prevent periodic variations in the bit clock 
duty cycle from spatially aligning with each other in the process direction during the 
printing of adjacent scan lines.  
     In a printer having a prismatic scanner, a different predetermined pseudo-random offset 
value is advantageously provided for each facet of the prism (12), whereby the offset value 
for any given facet can be retrieved from a table look-up memory under the control of a 
scan counter or the like to be applied to the frequency synthesizer alone or as an initial 
offset for a polygon signature correction value for the given facet.

capable of displaying a television image and the like. 
In the display apparatus, after data included in an 
effective segment of an input signal have been

transmitted within a time period corresponding to the 
horizontal blanking period and also the vertical 
blanking period, to the read digital data. The 
resultant digital data are transferred to a display 
unit.
