Patent EP-0094671-A3 (EP)
Title: Method for data transmission
IPC: G06F11/10
Filed: 1983-05-16
Abstract: In the recording/reproducing of digital audio signals, errors are detected and corrected by using two parity words, one arranged at the center of the block formed of data words and the arranged at one end of the block. The probability that uncorrectable error will be present in the center of the block is relatively high, so placing the parity word there prevents loss of the more valuable data. Maximum correctable burst errors are determined by the length of the block, so placing the other parity word on the end of the block lengthens it and improves burst error correction. The parity words are arranged as indicated before adding a cyclic redundancy check (CRC) code to the data signal and then modulation coding the signal before recording. During playback, the reproduced signal is demodulated and the CRC code used to detect errors for which error pointers are generated. The reproduced data is read into memories (3,4) in accordance with generated addresses and the pointers prevent the writing in of words found to be in error, which error words are subsequently corrected if possible using parity codes originally encoded into the signals prior to recording.

Title: Process for making a glass object, especially a preforn for drawing optical glass fibres
IPC: C03C13/00
Filed: 1983-09-22
Abstract: Preforms for drawing into glass fibers are relatively quickly produced by extruding filaments or tapes from polysiloxanes and/or heteropolysiloxanes and curing such filaments. A cylindrical wound body is produced from such cured filaments by winding such filaments onto an arbor. The wound body is converted, by heating in an oxidizing atmosphere, into an oxide body composed of SiO2 and, under certain conditions, containing doping amounts of select heteroelements present in the heteropolysiloxane. After removal of the arbor, a gas stream containing chlorine gas is flushed at a temperature of about 1000 DEG  to 12,000 DEG  C. through the oxide body to remove any traces of water and the dry oxide body is sintered into glass at a temperature of about 1200 DEG -1500 DEG  C. The tubular preform thereby attained is collapsed and a glass fiber is drawn therefrom. This process is particularly suitable for the fabrication of gradient optical fibers. A desired refractive index profile can already be taken into consideration in the production of the wound body.

Title: Non spill liquid fuel tanks
IPC: B60K15/00
Filed: 1983-03-14
Abstract: A liquid fuel tank for a vehicle is provided with a fuel outlet duct in a circuit about the base of the tank and fuel outlet duct vents connected to the outlet duct and extending above the highest part of the tank. During normal operation of the tank, a non-return air vent allows the flow of fuel from the outlet duct. In the event of an accident, or some other occurrence which results in the tank being tilted, further fuel flow from the outlet duct is cut off by air drawn into the fuel outlet duct from the outlet duct vents. The angle through which the tank must be tilted to allow air from the outlet duct vents to be drawn into the outlet duct may be predetermined by the extent of the circuit about the base of the tank of the outlet duct. Such a non-spill fuel tank, which is self contained in operation, is suitable for use in on-road and off-road wheeled and tracked vehicles, hovercraft, and aircraft which are in danger of being blown over when on the ground.

Title: Thermochemical energy storage
IPC: C09K5/06
Filed: 1983-08-04
Abstract: A thermal energy storage medium comprising a hydrophilic polysaccharide supporting an inorganic salt that is capable of transforming from one phase to a less hydrated phase absorbing latent heat, and releasing this latent heat upon the reverse transformation. The polysaccharide, preferably Xanthan Gum, may be incorporated in concentrations of 0.05% to 3% together with a nucleating agent in order to form a material that transforms when cooled back to the transformation temperature, or in greater concentrations of 1% to 5% without a nucleating agent to form a material that may be cooled below the transformation temperature without transformation taking place, and stored at ambient temperature whilst still storing the latent heat until activated.The medium is gelled in the less hydrated phase and in some embodiments the gel is pseudoplastic thus enabling it to be poured into chambers of an energy storage device, and then regain its original viscosity at rest.

Title: Microprogramme sequence controller
IPC: G06F13/24
Filed: 1985-05-07
Abstract: The instructions are in a set of which each instruction includes a word with bits arranged in fields. The controller communicates with external devices over an input data bus, an instruction word bus and the output data bus. The comparator register (128) connects with an internal bidirectional data bus (110) for receiving and storing temporarily the instruction address. The comparator (129) is connected with the comparator register to receive the stored instruction address and with the lines (174) of the output data bus to receive the instruction address generated by the microprogram sequence controller on the output data bus. When these two instructions are equal the comparator signals the equality.

Abstract: A method and apparatus for validating a moving coin by detecting an oscillating signal generated in coils connected in a tuned oscillating circuit. A property of the signal which varies linearly with coin displacement in one direction for a first period and varies linearly in an opposite direction with coin displacement for a second period is measured. From measurements made during the first and second periods a signal characteristic of the coin, and substantially independent of the coin's velocity is derived. The coin is validated by comparing this signal with stored reference values.

Patent EP-0235625-A3 (EP)
IPC: H05K1/02
Filed: 1987-02-11
Abstract: Repair of defects in a printed circuit board (10), the defects including a 
break (22) in a strip conductor (14B) and a short (24) between two strip 
conductors, is accomplished by use of a milling machine cutter (26) which 
is operated in a direction normal to a surface of the board to bring the 
cutter to a repair site (30) at the defective conductor. The cutter is 
then advanced partway into the conductor and translated along the 
conductor in preparation for soldering or braze repairing a break or, 
alternatively, the cutter is advanced beyond the depth of shorting 
material after which translation along the surface serves to rout out 
shorting material. Transverse movement of the cutter also removes any 
coating which may be present on the circuit board, which coating need be 
removed prior to soldering or braze repair, and may be replaced after 
soldering or braze repair. A microscope (32) and pellicule (34) are 
positioned for aligning the cutter with the repair site. Repair is 
accomplished by a method including the establishment (60, 20) of an 
electric potential (56) between a portion of the faulty conductor (14B) 
and the cutter (26), there being a change in voltage upon a contact of the 
cutter with the conductor, which change in voltage signals (58) such 
contacting, thereby to allow for precise positioning of the cutter.
