Inventor: DUFRANE RONALD M
IPC: C06C5/06
Filed: 1991-01-28
Abstract: A delay train ignition buffer (45) is positioned between a transmission tube (11) and a delay train (25) in a detonator housing (15) or a signal transmission tube housing.  The buffer controls the rate at which the transmission tube temperature/pressure pulse is applied to the delay train pyrotechnic surface, attenuating the effects of the pulse with a resulting improvement in delay timing precision.  The buffer also attenuates the effects of sudden depressurization within the detonator resulting from the rupture of the transmission tube or ejection of the tube from the housing, thereby preventing separation of the reacting pyrotechnic which could otherwise cause the reaction to cease at the point of separation, thus causing failure of the delay train to continue combustion of the pyrotechnic through its length.

Abstract: ABSTRACT OF THE DISCLOSURE           There is disclosed a method for the detection of HIV-l envelope sequences by the polymerase chain reaction using inosine-substituted "consensus" primers.  The primers, modifications of SK68 and SK69, are highly specific and sensitive and they prevent false-negative results due to variation in the HIV-1 genome.  Consensus primers are needed to ensure the detection of most, if not all, variants of HIV-l including American, African and newly emerging strains.  The primers are of particular value for HIV polymerase chain reaction testing of dry blood samples providing similar specificity and sensitivity.

Title: Multi-level error correction system
Inventor: WENG LIH-JYH
IPC: G06F11/10
Filed: 1991-04-25
Abstract: ABSTRACT       A system separates data into "i" interleaved sections of "k" symbols each and encodes each section using a relatively weak (n,k) ECC.  It generates for each k symbols an n symbol code word containing "n-k" or "r" redundancy symbols, or a total of "ri" redundancy symbols.  The system segments the ri redundancy symbols into "m" multi-symbol sections, namely, R(1), R(2), ... , R(m), which contain corresponding symbols from each of the i code words.  The system then encodes each of these sections using various ECC's and generates Q(2), ..., Q(m) redundancy symbols, respectively.  The system then records just the data, the section R(1) redundancy symbols and the Q(2), ...,Q(m) redundancy symbols.  When the system later retrieves the data, it decodes it code word-by-code word using the level-1 ECC and fills in the R(2), ..., R(m) redundancy symbols in each code word.  It also corrects, if possible, any errors in the data.  If the level-1 decoding does not correct all the errors, the system uses the Q(2) redundancy symbols and the level-2 ECC to fill in missing section R(2) coda word symbols and tries to correct the corresponding code words using the level-1 ECC.  If necessary, the system fills in redundancy symbols in the next section, i.e., section R(3), using the Q(3) symbols and the level-3 ECC.  It then uses the level-1 ECC to correct more errors in the data, and so on.

Abstract: An adapter for connecting an electrical load which is mobile, such as the electrical system of a pleasure craft, to a stationary power source, such as the electrical pedestal at a marina. In its preferred embodiment, the adapter serves to connect a higher voltage load (such as a 240 volt electrical load of a pleasure craft) to a pair of conventional 120 volt sources, Input cables include a pair of connectors for independent connection to sources on the pedestal. Isolation means within the adapter serves to isolate the input connectors from each other during the connection operation such that a user holding one connector while connecting the other will not receive an electrical shock. Sensing means within the adapter determines that the sources are in the proper relationship to sum to the level required by the mobile load. When the sensing means determines that the sources are connected and in the proper relationship, contacts are closed connecting the summed inputs to the output for driving the load.
Patent CA-2042975-A1 (CA)
Inventor: TERAUCHI KIYOSHI
IPC: F04C29/00
Filed: 1991-05-21
Abstract: A scroll type fluid displacement apparatus is disclosed. A driving mechanism includes a drive shaft which is rotatably supported by the compressor housing. A crank pin eccentrically extends from an inner end of the drive shaft and is drivingly coupled to a bushing. The bushing has a central axis which is offset from the central axes of the drive shaft and the crank pin. The bushing transmits orbital motion to the orbiting scroll thereby developing line contacts between the spiral elements. A first line can be defined passing through the central axis of the drive shaft and the central axis of the bushing, a second line can be defined passing through the central axis of the bushing and perpendicular to the first line, and a third line can be defined between the central axis of the bushing and the central axis of the crank pin. As the bushing rotates about the crank pin, a reaction force due to the compressed gas is exerted on the central axis of the blushing. When abnormal reaction forces due to the compressed gas are exerted on the central axis of the bushing, a control mechanism reduces the angle between the second line and the third line. Thus, the sealing forces between the fluid respond to changes in compressor output and anti-wearing of the surfaces of the spiral elements can be assured.
