Patent GB-1254667-A (GB)
Title: Holographic data storage system
IPC: G11C13/04
Filed: 1970-07-29
Abstract: 1,254,667. Uses of photochromism. INTERNATIONAL BUSINESS MACHINES CORP. 29 July, 1970 [7 Aug., 1969], No. 36666/70. Heading C4S. [Also in Divisions G2 and H3] In an optically accessible data store, information is holographically recorded by two beams of light incident on opposite sides of a reversible photochromic or magnetic medium. In Fig. 6, a beam from a write laser 10 is split into a reference beam 10b and a component beam 10c. The former beam is incident on one side of a holoarray 14, and the component beam is directed on to a pattern formation structure 13 which modulates the beam with the data to be stored. The component beam passes from the pattern structure 13 on to the other side of the holoarray, and the data is recorded as a hologram. To read the data out of the holoarray a second laser 11 is used, and in practice this laser has a frequency differing from that of the write laser. The reconstructed hologram activates a photodetector array 12. The beam deflection apparatus necessary to select a given hologram in the holoarray is not shown. The spatial disposition of the various parts of the apparatus is described, Fig. 10 (not shown). Pattern formation structure.-Fig. 1 shows a reflector 1b on which is mounted an electro- or magneto-optic polarization rotating material 1a and a polarizer 1c. By controlling the material la with a pattern of electrodes or solenoids, the reflection of selected areas of the structure may be varied according to the data to be stored. The reflector 1b may be replaced by a second polarizer, in which case the structure is used in transmission rather than reflection. An alternative patterning structure uses a silver halide in a glass plate; such a plate may be rendered reflective by light of a first wavelength from an array of light emitting diodes, whilst light of a second wavelength makes the plate transmissive, i.e. erases the pattern. The light from the write laser is at a third frequency which does not alter the pattern in the plate. A further form of patterning structure uses a magnetic medium whose magnetization is controlled by Curie point optical writing. The magnetization pattern in the medium affects the polarization of the write laser's component beam. Such a patterning device is shown in Fig. 5a, and ferrite rings 51 mounted on the magnetic medium are used to erase any selected part of the pattern. Each ring is associated with a coil connected to a matrix of wires 6 and 7, so that by pulsing an appropriate pair of wires any selected part of the magnetic medium may be saturated, i.e. erased. Data storage medium.-The holograms are recorded in the above described photochromic material, or by using a magnetic material and the Curie point optical writing technique. In the photochromic case, the holograms may be erased by a separate laser, Fig. 9 (not shown). When a magnetic recording material is used it may be as shown in Fig. 5a, each ferrite ring covering one hologram and being used to erase it.

Title: Improvements in artificial dispersions of rubber
IPC: C08J3/03
Filed: 1938-12-22
Abstract: 503,399. Making rubber dispersions. DISPERSIONS PROCESS, Inc. Dec. 22, 1938, No. 37281. Convention date, Jan. 13. [Class 1 (i)] Artificial aqueous dispersions of rubber, which are compatible with latex even at high concentrations of solids, are made by dispersion in water with the aid of a soap, the acid radicle of which is saponified by means of an alkali silicate. Dispersion is effected by breaking down crude or reclaim rubber and masticating it with the dispersion medium and dispersing agent, or materials reacting to form such agent, in a mixer, e.g. of the Werner and Pfleiderer type. The soaps may be formed from oleic, stearic, palmitic and abietic acids and rosin and the alkali silicates may vary from 2R2O.SiO2 to R2O.4SiO2 where R is an alkali metal. Alkali hydroxides may be added to silicates having a low ratio of alkali to silica, and the alkali content of the dispersion is preferably not more than 2 parts. of sodium hydroxide per 100 parts of rubber. The products may have a solids content of 30-50 per cent, and possess a lower viscosity than dispersions made with alkali-hydroxide saponified soaps, although dispersions made with stearic or palmitic acids possess higher viscosities than those made with the other soap-forming acids. Any excess of soapforming material not saponified is dispersed with the rubber and may act as a compounding ingredient. The dispersions form stable mixtures with latices and may be vulcanized or used as coatings for waterproofing or non-slip purposes or as a base for pile fabrics.
