Title: Anordning for å innstille et teleskops sekundærspeil i forhold til dets primær-speil, og teleskop med slik anordning
Inventor: SAYEDE FREDERIC NOEL
IPC: G02B23/00
Filed: 1996-05-30
Abstract: Anordning for presis posisjonering av et teleskops (1) toppunkt (5A) av et sekundærspeil (5) i forhold til et sentrum (0) som er bestemt av toppunktet (3A) av teleskopets primærspeil (3). Posisjoneringen skjer ved fininnstilling av en festeinnretning (9) som forbinder sekundærspeilets (5) sentrale holder (8) med en fremre ramme (4) i teleskopet, idet det er denne ramme som holder speilet (5).Festeinnretningen (9) utgjøres av krysstående forbindelsesarmer (10) på hver side av holderen (8) og med utstrekning hhv i en første retning (X-X) og en andre retning (Y-Y) ut fra holderens sentrum (0). Ved at forbindelsesarmene (10) er utformet som flate lister kan de bøye utnoe i én retning, men er stive i de to øvrige ortogonale retninger. En aktuator (11) i enden av hvert par forbindelsesarmer (10) kan forskyve sitt respektive armpar noe i lengderetningen.

A method of treating a fluid in a housing comprising a fluid inlet, a fluid outlet, a fluid treatment zone disposed between the fluid inlet and the fluid outlet, the fluid treatment zone having at least one radiation source disposed therein is also described. The method comprises the steps of: (i) providing a flow of the fluid to the fluid inlet; (ii) feeding the flow of fluid from the fluid inlet to the fluid treatment zone in a manner substantially parallel to the at least one radiation source; (iii) irradiating the flow of fluid in the fluid treatment zone; and (iv) feeding the flow of fluid to the fluid outlet. During the method, the flow of fluid through the fluid inlet, the fluid outlet and the fluid treatment zone is substantially collinear. The fluid treatment device and method are ideally suited (but not limited) to inactivate microorganisms present in water.

Abstract: 1481850 Determining leak location electrically B BRANDES 25 July 1974 [26 July 1973] 32875/74 Heading G1N To determine the position of a leak 10 from an electrically conductive pipe-line carrying fluid, a ninevolt battery is connected to the pipe-line by a line 20 whereby if a leak occurs to short the pipe-line to a signal conductor 6, fastened to the pipe-line but insulated from it in the absence of a leak, current flows via line 20, the pipe-line, conductor 6, and resistor 26 to cause changeover of switch 27. Thereby the positive pole of a twenty volt battery is connected to one end 13 of the conductor 6 of which the other end 11 returns to the battery via diode 24 and line 23, the potential across the conductor being stabilized by a Zener diode 25. The voltmeter 12 thus lies in a measuring loop constituted by diode 31 line 32, the pipe-line, that length of the conductor 6 lying between the leak and the end 11, diode 24 and line 23. Thus the voltage indication on the voltmeter represents the distance of the leak from a datum point on the pipe-line, usually the end of a line segment disposed in a manhole. An amplifier 33 is disposed across a resistor 29 disposed in the line 28 from the twenty volt battery to the conductor 6 and acting in response to current flow in the line 28 to cause the voltmeter to retain its reading. The voltmeter may be a digital voltmeter.

Abstract: 1536048 Photo-avalanche diode bias circuit HUGHES AIRCRAFT CO 23 July 1976 [27 Aug 1975] 30832/76 Heading G1A [Also in Division H3]  A bias circuit for photo-avalanche diode 19 comprises a capacitor 22 in parallel with the diode 19, means for charging the capacitor to a voltage sufficient to cause avalanche breakdown of the diode in response to a first timing pulse and means for reducing the capacitor voltage by a predetermined amount in response to a second timing pulse. The circuit may be used in a laser rangefinder. As shown, monostable 11 generates the first timing pulse 13 (duration t 1 ) and monostable 12 generates the second timing pulse 14 (duration t 3 ). The monostables are triggered by the leading and trailing edges respectively of laser timing pulse 10 (duration t 1  + t 2 ). During the first timing pulse, transistor Q1 is switched on and current from battery 16 flows through transformer primary 15  storing energy therein. During period t2, the energy induced in transformer secondary 17 charges capacitor 22 via diode 18, resistor 23 or diode 19 and battery 24 to the avalanche breakdown voltage of diode 19, at which voltage diode 19 breaks down, holding the capacitor charge at that value. During period t 3 , transistor Q 2  is switched on, connecting one end of capacitor 22 to earth and reducing the bias voltage on diode 19 to a voltage below the avalanche breakdown voltage by an amount equal to the voltage of battery 24. The circuit will therefore function with diodes of different avalanche breakdown voltage. The circuit biases the diode in a few hundred micro-seconds.

Abstract: A method of making coreless hollow filament bundles comprises winding a hollow filament 20 around a drum 22 having a number of axially extending vanes 24. The winding is formed in layers, each layer being a helix and adjacent layers being wound in opposite directions axially of the drum so that all the turns of the helix forming one layer cross all the turns of the helices forming the adjacent layers. The winding is then slid along the drum so that it is axially collapsed and forms an annular rope around one end of the drum. The annular rope is then cut into segments, each segment being the length of rope between adjacent vanes 24. Each segment forms a filament bundle and the ends of the filament lengths in each bundle are potted in the usual way.
