Title: Fuel pressure intensifying device for an internal combustion engine
Inventor: HOFMANN KARL
IPC: F02M55/02
Filed: 1998-08-18
Abstract: A fuel supply system for an internal combustion engine has a low pressure source 5, a high pressure pump 1, a fuel injection nozzle valve 7 and a hydraulic intensification device 13 positioned between the high pressure pump 1 and the nozzle valve 7. The intensification device comprises a stepped pistol, 19 whose end faces each define a pressure chamber 23, 27 and a supply duct, which contains a non return pressure valve 45 and preferably a rod filter 57, and allows chamber 27 to be filled with fuel from chamber 23. Pressure intensification results from the different surface areas D1, D2 of the end faces of the piston 19 and is proportional to their ratio. In this embodiment the supply duct is provided by a through-going bore 43 in the piston 19. In other embodiments (figure 2A, 3A, 3B) the supply duct may be provided in the housing of the device. A restoring force may be exerted on the stepped piston 19 by a spring 37 which abuts against an annular collar 29 on the piston 19.

Title: Encoding a binary shape signal using context based techniques
Inventor: CHO SUNG-RYUL
IPC: H04N19/00
Filed: 1998-12-18
Abstract: An apparatus encodes a binary shape signal by using an adaptive context-based arithmetic encoding technique. To this purpose, the apparatus includes a first encoding block for encoding the binary shape signal by using a first context-based arithmetic encoding technique 130 for processing the binary shape signal on a pixel-by-pixel basis to thereby generate first encoded data, a second encoding block for encoding the binary shape signal 150 by using a second context-based arithmetic encoding technique for processing the binary shape signal on a subblock-by-subblock basis to thereby produce second encoded data, wherein the binary shape signal is partitioned into a multiplicity of subblocks and the number of pixels in each subblock is smaller than the number of pixels in the binary shape signal and larger than 1. A bit calculation block ciphers the numbers of bits of the first and the second encoded data and compares the calculated numbers with each other. A selection block choses either the first or the second encoded data whose bit number is smaller than that of the other based on the comparison result and providing the selected data as the encoded binary shape signal.

Title: Self-locking threaded connection
Inventor: WU MARK
IPC: F16B39/30
Filed: 1999-10-29
Abstract: A fastener includes a threaded male and female elements (22, 21) having thread forms defined by a leading flank and a trailing flank. Each of the flanks of one of the elements (21) has a root-connecting oblique surface (216) and a crown-connecting oblique surface (215) that intersect to form an obtuse angle therebetween. The crown-connecting oblique surface (215) is parallel respectively to the flank faces, and forms a large angle (24) with the thread axis (23), while the root-connecting oblique surface (216) forms a small angle (25, 45) with the thread axis (23, 43). When the crown of the one of the elements is brought into contact with either of the root-connecting oblique surfaces of the other one of the elements (21) the elements (21 and 22) are locked effectively together. The oblique surfaces may alternatively be formed on the flanks of the male element (Fig. 7)

Title: Protecting high voltage power distribution transformers from lightning strikes
Inventor: DOONE RODNEY MEREDITH
IPC: H02H7/04
Filed: 1997-06-03
Abstract: Even when the terminations of the high voltage winding or windings 2 of a power distribution transformer 1 are protected by surge arresters or diverters 7, 8 connected to ground via the transformer casing 5 and casing earth connection, a lightning strike may cause transformer failure due to the surge current (typically 10KA) passing through the surge diverter 7 or 8 and the casing ground resistance Rc-e (typically 10 ohms) giving rise to a transient voltage (typically 100KV) on the casing 5. This transient voltage appears between the casing 5 and the grounded neutral termination of the low voltage winding 3 of the transformer and exceeds the withstand voltage of the low voltage winding. To overcome this problem, a high voltage surge arrester 10 is connected between the casing 5 and the neutral termination of the low voltage winding 3. The surge arrester 10 is chosen to clamp the transformer casing 5 to a voltage (eg. no greater than 20KV) which is below the withstand voltage (eg. 25KV) of the low voltage winding 3. When used in a distribution system having auto-reclosing type circuit breakers on the high voltage side, the arrester 10 must also be able to withstand, for the remake period of the circuit breaker, a fault voltage to which it will be subjected when a ground fault exists on the high voltage side. In an 11KV distribution system, arrester 10 must withstand 7KV for 10 seconds under such ground fault conditions. The transformer 1 may be pole-mounted, and additional protection may be provided by connecting the low voltage lines to ground by means of low voltage surge arresters located at the next pole downstream of the low voltage side of the transformer.

Title: Method and reagent for determining specific nucleotide variations
IPC: C12Q1/68
Filed: 1991-02-12
Abstract: Detection of variable nucleotide(s) is based on primer extension and incorporation of detectable nucleoside triphosphates. By selecting the detection step primers from the region immediately adjacent to the variable nucleotide, this variation can be detected after incorporation of as few as one nucleoside triphosphate. Labelled nucleoside triphosphates matching the variable nucleotide are added and the incorporation of a label into the detection step primer is measured. The selection of the detection step primer is important to the method according to this invention and is dependent on the nucleotide sequence of interest. The detection step primers are preferably selected so to span the region immediately toward the 3' end from the variable nucleotide to be detected. The method is useful in identifying specific point mutations and genetic variations.

Title: Combustion apparatus
Inventor: FUJIWARA NOBUHIKO
IPC: F23D11/44
Filed: 1998-01-22
Abstract: PROBLEM TO BE SOLVED: To shorten preheating time of a vaporizer at ignition in a combustion apparatus which burns a liquid fuel such as kerosene by vaporizing it. SOLUTION: A heater 12 (heating means) is provided to heat and vaporize a liquid fuel and a secondary battery cell 24 (storage/discharge means) to store or discharge electric energy and at ignition, the heater 12 generates heat by discharging of the secondary battery cell 24. As a result, the secondary battery cell 24 can discharge a large power exceeding the capacity of a commercial power source in a short time to make the heater 12 generate heat. This enables shortening of preheating time and hence, quick ignition. In addition, the shortened preheating time can significantly restrict the scattering of heat energy thereby yielding an effect in the saving of energy.
