Title: Acoustical deflection apparatus for electromagnetic waves
IPC: G02F1/335
Filed: 1972-06-14
Abstract: 1389258 Deflecting light; acoustic-optic devices INTERNATIONAL BUSINESS MACHINES CORP 14 June 1972 [30 June 1971] 27709/72 Headings H4F and H3U In an optical deflector of the type wherein a light beam undergoes Bragg or Raman-Nath diffraction in a medium traversed by a acoustic wave, and as a function of the acoustic frequency f a , the medium exhibits dispersion for the particular type of acoustic wave employed, i.e. the acoustic phase velocity V a  is a function of f a . In particular if #V a /#f a  is negative, the deflector has increased resolution. Dispersion may arise from the properties of the medium itself, e.g. if the lattice period # the acoustic wavelength # a , or, as in the preferred embodiments, from boundary conditions, e.g. if the medium is a film having a thickness ## a . In a first case, a thin film is provided with an electroacoustic tranducer and an acoustic termination of black wax or mercury, and light is transmitted through the film. In a second case the film is sputtered, evaporated or otherwise grown on a substrate to a thickness of 1-10Á and is preferably piezoelectric. An interdigital transducer, or a prism plus acoustic transducer, introduce bulk shear, Rayleigh, Love or Seyawa (M-Z) waves into the film (depending on the relative phase velocities of the various waves in the film and substrate). The light beam passes through the film and is specularly reflected at the film/substrate interface. In a variant, the film is a liquid (water held by surface tension), or solid (SiO 2 ) between two substrates (LiNbO 3 , glass, quartz and the acoustic waves are initiated in one of the substrates. A particular acoustic mode for which the phase velocity is the film is less than that in the substrate will selectively move to the film. In a further embodiment, a transducer produces Lamb (guided bulk), waves in a film on a substrate. In a final embodiment, the film on a substrate also acts as an optical waveguide, and an optical grating coupler is provided, diffraction occurring in the film plane. The acoustic termination may be omitted, whereupon reflected acoustic pulses may be used to deflect the light beam, or it may be replaced by a further electro-acoustic (receiving) transducer. It is also noted that both guided acoustic bulk waves (dispersive) and surface waves (non- dispersive) may be simultaneously generated by an interdigital transducer on a LiNbO 3  YZ slab, both being effective to diffract a light beam, with the former waves giving a threefold improvement in resolution.

Title: Programme branching and register addressing procedures and apparatus

Filed: 1972-06-14
Abstract: 1391507 Program branching for interrupt handling; indirect addressing SANDERS ASSOCIATES Inc 14 June 1972 [21 June 1971] 27864/72 Heading G4A A computer includes an instruction address register and means for modifying the contents of the register to cause a program branch by comparing two N bit operands to determine the lowest ordered bit position in which both operands contain a binary bit of a particular significance and incrementing the contents of the instruction address register by Y + 1 where Y is N minus. The order of the determined bit position, the bit positions ranging from 0 to N-1. The computer includes a processing unit, a program store which may be read only, and a plurality of registers including an instruction address register and an interrupt request register which are selectively connectable to the processing unit via A, B, and D serial buses. The registers may be connected in parallel to a group of peripherals, e.g. a keyboard, CRT, &c. which may be the source of interrupt requests. When an interupt occurs a respective bit position in the interrupt request register is set and an "interrupt" signal generated. The signal causes the contents of the instruction address register to be loaded into a push down stack for a subsequent return and the, zero, contents of the instruction address register used to access an interrupt request processing routine. This routine includes a so-called "mask and branch" instruction which has two fields causing two selected registers to be connected to the A and B buses. One of the registers is the interrupt register and the other a register containing a previously loaded mask, which may be all zeroes, The A and B buses are connected through an AND gate with the all zero mask being complemented. The contents of the registers are clocked on to the buses so that the AND gate produces an output at the lowest order bit position at which both bits are one. A bistable is set to enable a further AND gate receiving the clocking pulses so that the further gate produces a number of pulses dependent on the bit position at which the bi-stable was set. These pulses are used to increment the instruction address register which is normally incremented once per cycle to access successive program instructions. The number of registers may be greater than the limit imposed by the A and B register selection fields within an instruction, which, as described, is sixteen. One of the sixteen registers is used for indirect addressing. The register is eight bits long and is divided into two halves which may be directly addressed. The contents of the register or the selected half thereof are fed to A and B decoders which each select one of sixteen registers. The extra registers may be shared by identical peripherals so that the peripherals may share common program routines.

Title: Improvements in or relating to the preparation of rubidium compounds
Inventor: SYKES PETER WILLERTON
IPC: C01D17/00
Filed: 1956-09-12
Abstract: Rubidium is recovered from a dilute aqueous solution containing rubidium and caesium, with or without other alkali metal salts, by fractionally precipitating caesium as caesium chlorostannate, by addition of an aqueous solution of stannic chloride containing hydrochloric acid, and thereafter adding further amounts of stannic chloride solution to precipitate the rubidium as chlorostannate.  The initial stannic chloride solution is preferably in stoichiometric excess relative to the caesium.  The invention is particularly applicable to the treatment of chloride solutions obtained by the extraction of lepidolite after removal of lithium followed by concentration and crystallization of sodium and potassium values as chlorides.  According to examples, a filtrate from the lepidolite extraction process above outlined and still containing lithium, sodium, potassium and caesium chlorides as well as rubidium chlorides, was treated with soda ash to precipitate lithium as carbonate, cooled, treated with concentrated hydrochloric acid to precipitate sodium and potassium chlorides and then treated with stannic chloride and concentrated hydrochloric acid until a filtered test portion gave no precipitate with iodobismuthic acid.  Caesium chlorostannate was removed and further stannic chloride was added with agitation and the rubidium chlorostannate was recovered.  This was treated with barium carbonate at about 90 DEG C. to form alpha-stannic acid, which was filtered off, and a solution of rubidium and barium chlorides from which the barium was precipitated as sulphate with sulphuric acid.  The rubidium chloride may be purified by dissolving in water, adding concentrated hydrochloric acid and then treated with stannic chloride to precipitate further caesium chlorostannate as impurity, after which the rubidium chlorostannate was treated as before.  Alternatively the crude barium chloride/rubidium chloride solution obtained by barium carbonate decomposition of the rubidium chlorostannate may be treated with concentrated hydrochloric acid to precipitate most of the barium and then treated with stannic chloride to precipitate rubidium as chlorostannate as before.  The alpha-stannic acid can be reconverted to stannic chloride by boiling in hydrochloric acid and the solution recycled for precipitation of the chlorostannates.
