Title: Optical sighting devices
IPC: G02B27/64
Filed: 1976-09-29
Abstract: 1531289 Sighting devices FRANCE ARMED FORCES - MINISTER OF and SOC DE FABRICATION D'INSTRUMENTS DE MESURE (SFIM) 29 Sept 1976 [1 Oct 1975] 40371/76 Heading G2J In a sighting device of the kind in which a reflector is mounted for rotation about the axis of a rotatable hood so as to direct radiation transmitted through an aperture in the hood along said rotation axis, the hood is provided with two windows each transparent in a different spectral range, and the relative position of hood and reflector can be changed to select which window is used.  As shown, Fig. 1, the hood 1 is provided with windows 2, 3 and the reflector 6 directs radiation to a beam-splitter 8 which reflects I. R. to detector 9. Visible light is transmitted and then reflected by beam-splitter 10 to visible detector 11. Radiation in the overlap region of the windows 2, 3 is transmitted by splitter 10 and is passed to detector 13 (e.g. a goniometer). Detector 13 may be an axis. Normally reflector 6 and hood 1 are gauged for simultaneous rotation, but to change windows the hood may be rotated relative to the reflector. In an alternative, Fig. 2 (not shown) the first beam-splitter transmits IR to detector 9, and reflects visible to the second splitter, which in turn transmits "overlap" wavelengths and reflects visible light.

Specified complexes are (C5H5)2TiCl2AlCl2 and (C5H5)2TiCl2AlClEt.  Use of the complexes in the polymerization of ethylene is also mentioned, but not claimed.ALSO:The invention comprises compounds of formula (C5H5)2TiX1XAlXY wherein C5H5 is cyclopentadienyl, X, X1 and Y are halogen atoms, or Y is C2-C5 alkyl.  Specified compounds are (C5H5)2TiCl2AlCl2 and (C5H5)2 TiCl2AlClEt; they may be prepared by reacting a bis-cyclopentadienyl-titanium monohalide (e.g. chloride) (obtained from titanium trihalide and sodium cyclopentadiene) with either AlCl3 or AlCl2R1 (e.g. R1 = Et).

Title: Method of establishing information
IPC: G03H1/00
Filed: 1976-09-30
Abstract: 1507236 Holographic identity documents AB-ID KORT 30 Sept 1976 [1 Oct 1975] 40646/76 Heading B6A [Also in Divisions G4 and G2] The techniques of holographic interferometry as applied to secret recording and subsequent recovery. The object beam is slightly modified in coded manner between two exposures on different recording media, whereby the reconstruction of the sandwiched developed holograms yields interference fringes bearing the coded information. In the preferred embodiment the object bears an array of piezoelectric transducers whose dimensions can be selectively varied between exposures. Alternatively other mechanical object deformations may be used, or the path length between object and hologram may be modified by, e.g. Kerr cells, Pockels cells, or by changing the conditions (e.g. pressure, temperature or composition) of the contents of fluid filled cells. The invention is particularly suited to the encoding of credit cards wherein copies of the first (unmodified) hologram are held by banks, and the encoded hologram is included in the card. Only by superposition of the two in appropriate orientation allows reconstruction of the encoded information.

Filed: 1972-09-05
Abstract: 1397152 Semi-conductor data storage INTERNATIONAL BUSINESS MACHINES CORP 5 Sept 1972 [1 Oct 1971] 41079/72 Heading H3T A digit storing capacitor C s  is read by first discharging a line capacitance C L  into it and then recharging C L  from a detector capacitor Cd whose resulting charge then represents that originally stored on C s . This enables a line 26 having a relatively high capacitance C L  to be used without ill effect. The read sequence involves firstly applying # 1 , # 2  pulses (at T1 time, Fig. 4, not shown) to turn on F.E.T.'s 30, 31 and charge C L  to # 1  voltage minus the threshold voltage of F.E.T. 30. After (# 1 , # 2  have ended (T2), # 3  is applied to charge Cd to # 3  minus the threshold of F.E.T. 32, so that C d  and C L  are at approximately the same voltage. Then (T3) F.E.T. 10 is turned on by word driver 12 to discharge C L  by an amount depending upon whether a 1 or 0 was stored. Finally # 1  turns on F.E.T. 30 (T4) to apply the charge on C d  plus a further 91 voltage to C L , and thereby to recharge C L  to the # 1  voltage minus F.E.T. 30 threshold. The remaining charge on C d  is measured by a voltage sensitive amplifier 15. Writing merely involves turning on F.E.T. 10 and supplying either a 1 from bit driver 13 or a 0 from earth, through appropriate contacts of a switch 28. Bipolar transistors may be used.

Title: Purification of steam
IPC: B01D53/34
Filed: 1960-12-13
Abstract: Steam containing volatilized organic impurities, for example that obtained by the wet-air oxidation of sulphite liquor, is freed from said impurities by passing the steam together with a free-oxygen containing gas into an aqueous solution of an alkaline scrubbing agent at temperatures above 150 DEG C. and below 374 DEG C. and at superatmospheric pressure, whereby a reaction occurs between the scrubbing agent and the organic impurities, and the products of this reaction are oxidized in situ to carbon dioxide and water, with simultaneous regeneration of the alkaline scrubbing agent. The alkaline scrubbing agent may be K2CO3, KOH, Na2CO3, NaOH, Li2CO3 or LiOH.  An oxidation catalyst may be employed, e.g. a noble metal, heavy metal or iron group metal or the oxides, phosphates or acetates of such metals, a mixture of silver oxide and manganese dioxide being specifically mentioned.  The quantity of free-oxygen containing gas used is preferably such that there is a 5% excess of oxygen over the stoichiometric amount required to oxidize the organic impurities present.
