Title: Modern pooling system
Inventor: MORI HIDEYASU
IPC: H04M11/06
Filed: 1991-06-18
Abstract: In a key telephone system with data terminals 371... 37n, e.g. computers, connected to a key service unit 1 connected to a plurality of telephone lines 251... 25m, a modem 43 is pooled for common use by the terminals 371... 37n. When called from a telephone line (e.g. 251), the key service unit 1 selects a single data terminal 371 ... 37n now being in standby status, and closes a communication channel between the selected data terminal (e.g. 371) and the modem 43, so that a status equivalent to that where the selected data terminal 371 and the modem 43 are directly connected is established. Thereafter, the key service unit 1 indicates a called party number signal reception to the modem 43, and the modem 43 transmits a call to the selected data terminal 371. When the selected data terminal 371 responds to the call from this modem 43, the key service unit 1 closes a communication channel so that a communication link between the selected data terminal 371 and the telephone line 251 can be established via the modem 43. Until this link is established, since the selected data terminal 371 and the modem 43 are in the status equivalent to direct coupling, the key service unit 1 is not concerned in the communications between the selected data terminal 371 and modem 43, thus reducing the operational load applied to the key service unit 1. <IMAGE>

Title: Diagnosis of malignant tumours by mRNA detection
Inventor: SELBY PETER
IPC: C12Q1/686
Filed: 1991-10-23
Abstract: A method for the diagnosis or monitoring of cancer or a malignant tumour associated with a particular body tissue of which the normal cells have at least one specific active gene that expresses a particular mRNA and protein characteristic of that tissue is disclosed which comprises taking a sample of peripheral blood or other body fluid in which cells of said particular tissue are not normally present and testing said sample for the presence of such tissue cells using a detection technique that relies upon detecting the activity of a selected said tissue specific active gene as manifested through expression or transcription producing said particular mRNA. The detection technique described involves extracting the total cellular mRNA present from the sample. using reverse transcriptase to prepare complementary DNA (cDNA) from the mRNA extracted, and then carrying out a polymerase chain reaction (PCR) process with appropriate primers so as selectively to amplify the cDNA corresponding to the mRNA transcribed from the selected tissue specific active gene, followed by analysis of the PGR products using, for example, gel electrophoresis or other conventional means.

Title: Downhole stabilizer
Inventor: ANDERSON CHARLES ABERNETHY
IPC: E21B17/10
Filed: 1994-05-12
Abstract: There is described a downhole stabiliser (10) for use in a drill string adjacent the drill bit. The stabiliser (10) includes a hollow and generally cylindrical casing (12) the outer surface of which defines three angularly spaced protrusions (24, 26, 28), the radially outer surfaces of which define a diameter which is marginally less than the diameter of the bore to be drilled. Two of the protrusions (24, 26) carry radially extensible and retractable spacer members (42 - 52) which are interconnected so that radially outward movement of one member (42 - 46) results in radially inward movement of the other member (48 - 52) and vice versa, effectively to vary the radial length of the respective protrusions. A control mandrel (56) is mounted within the casing (12) and is selectively movable between first and second positions. The control mandrel (56) further defines abutments (58, 60) for limiting the inward movement of the space members (42 - 52) and in the first position the mandrel permitting a greater degree of travel of one spacer member (42 - 46) than the other (48 - 52), and in a second position providing the opposite. The arrangement is such that, in use, the stabiliser (10) with the mandrel (56) in its first position causes the drill bit to veer laterally about a generally vertical axis in a first direction and with the mandrel in its second position the drill bit is caused to veer laterally in the opposite direction. <IMAGE>

Title: Spring cassette for latch mechanism
Inventor: COLLINS CALVIN N
IPC: E05B3/06
Filed: 1994-06-08
Abstract: A spring cassette comprises a housing in which a rotor 10 is adapted to co-operate and rotate with a shaft associated with a latch mechanism of a door or window, and a torsion spring 12 is disposed around the rotor 10 which interconnects the rotor and housing, biasing the rotor 10 towards a neutral, inoperative position relative to the housing.

Abstract: A photoelectric sensor includes a light emitting device LED2 and a light receiving device PD for detecting scattered light due to smoke, a light emitting confirming device LED1 which lights up when a quantity of light received by the light receiving device is greater than or equal to a threshold and a test light emitting device LED3 for emitting light to the light receiving device PD during the test, wherein a blinking of the light emitting confirming device LED1 is started at a time of a test start when reed switch 13 is closed, and a quantity of light received by the light receiving device PD is increased in steps so that the blinking is stopped when the quantity is greater than or equal to the threshold. Accordingly, the sensitivity test can be performed by visually counting the number of blinkings of the light emitting device LED1. Alternatively the elapsed time, or quantity of light, for the test period may be measured. <IMAGE>
