Title: Improvements relating to the production of iron oxide pigments
Inventor: HOLST TORSTEN GUSTAF HENRIK
IPC: C01G49/08
Filed: 1950-02-01
Abstract: Black to black-green iron oxide pigments are produced by reacting ferrous hydroxide with preformed yellow iron oxide, substantially consisting of \s1 -ferric-hydroxide, in aqueous suspension at the boiling-point.  The   -ferric-hydroxide may be suspended in ferrous chloride or sulphate solution, and ferrous hydroxide precipitated by hydroxides or carbonates of alkali or alkaline earth metals.  The precipitate is dried at 100 DEG C, and may be converted to red magnon-magnetic  -ferric oxide at higher temperature not exceeding 500 DEG C, or to red netic \yB-ferric oxide by ozidation at a temperatures.  A black pigment is produced on drying when the Fe2O3/FeO molecular ratio in the starting mixture varies from 0.5 to 1; at higher ratios, dark-green to yellowish green pigments are obtained.  The   -ferric hydroxide employed may be produced by the corrosion of scrap iron in iron sulphate solution by air and steam. Specifications 19190/05, 25859/05, [both in Class 34], 1050/06, 13848/09, [both in Class 1], and 433,333, and other previous publications, are referred to.

Title: Improvements in the production of emulsions or compositions of or containing organicpolysulphides and articles produced therefrom
IPC: C08G75/16
Filed: 1942-03-02
Abstract: Organic polysulphide plastics are obtained in emulsion form by reacting an aqueous emulsion of one or more aliphatic dihalides with a solution of a soluble inorganic polysulphide.  The product may be modified by subjecting the emulsion of the polymer, preferably under mildly alkaline conditions, to increased temperature.  Emulsification of the dihalides and purification of the polymer are effected in known ways.  The polymer emulsions may be applied in the manner of rubber latex, e.g. by spreading, dipping and extrusion, the polymer being converted to massive form by coagulation, e.g. by an acid.  In an example, ethylene chloride, emulsified in water with the aid of potassium oleate, was added gradually to an aqueous solution of sodium tetrasulphide maintained at 50 DEG  C.; after flocculation of the ethylene polysulphide, the polysulphide solution was decanted and the suspension stirred with water containing potassium oleate and the process of decantation and dilution repeated, further purification being effected by centrifuging and, after removing supernatant liquid the product was removed as a thick, white paste, which could be readily diluted with water.  In a second example, purification was effected with water containing sodium alginate and ammonia in addition to potassium oleate; a third example employed the sodium salt of sulphonated lauryl alcohol, together with glue as a protective colloid.

IPC: G11B25/04
Filed: 1952-02-01
Abstract: 714,621. Magnetic recording and reproducing apparatus. ARMOUR RESEARCH FOUNDATION OF ILLINOIS INSTITUTE OF TECHNOLOGY. Feb. 1, 1952, No. 2730/52. Class 40 (2). In a magnetic transducing apparatus for disc records the transducer 108 is carried by a hinged cover 11 and is brought into contact with record on a turntable 14 when the cover 11 is in the closed position. The transducer 108 is made to traverse the surface of the record by means of a leadscrew 96 which moves the transducer carriage 106 when a mechanical coupling between the leadscrew 96 and the turntable 14 is established upon the closing of the cover 14. The coupling takes the form of a one-to-one ratio worm gearing 99, a shaft 101 which enters a circular recess 105 in the central hub 15 of the turntable 14, and a pin 16 on the hub 15 which engages a radial pin 104 on the shaft 101. The carriage 106 is coupled to the leadscrew 96 by means of a spring-loaded tongue 114, Fig. 7, mounted on the carriage 106. When is it desired to traverse'the carriage manually, the tongue 114 may be disengaged from the leadscrew 96 by means of a lever 112, Fig. 6, whose end is terminated by an indicator 36, Fig. 3, on the outside of the cover 11. To carry out the operation the indicator 36 is merely pressed and then moved along an indexing card 34. As the leadscrews performs exactly one revolution to each revolution of the turntable, the transducer will always register correctly with a turn of the recorder track on the record disc which is itself accurately angularly located on the turntable 14 by means of a pin 18 thereon which engages a perforation in the record disc. The record disc comprises a base of paper, plastic or metal liaving a central aperture for engaging the hub 15 of the turntable 14, and has a magnetisable coating on each side. A clip at the centre or at the outer edge provides a convenient means for fastening the index card 34 associated with a particular record.

Title: Intruder detection systems
Inventor: FRISK LILIAN ROSE
IPC: G08B13/196
Filed: 1966-01-21
Abstract: 1,147,321. Intruder detection systems. L. R. FRISK, and C. GUNN-RUSSELL. 19 Jan., 1967 [21 Jan., 1966], No. 2881/66. Heading G4H. In an intruder detection system for a number of sites, e.g. strong rooms or the like, a television camera is provided in each site, giving a low definition output for transmission over an audio-type communication link to a television receiver at a central station. The central station OC is linked to some of the sites S by private telephone lines PL and to a telephone exchange E by telephone line T<SP>1</SP>. Other telephone lines T<SP>2</SP> connect the exchange to other sites S. Other links may use a micro-wave link MWL and a carrier wave link CWT. Communication between the central station and a selected site may be established by manual or automatic dialling or by operator. The camera at each site may be of the vidicon tube type having a wide aperture lens so that it is less easy to defeat the purpose of the system by placing a picture in front of the camera showing the details of the site as they should be. The camera may have a linear raster of 100 lines, interlaced, and may produce one picture in two seconds. The output signal, comprising frequencies of from 0À5 to 2500 cycles per second, is changed in a mains stabilized frequency changer to 300-2800 c/s. At the central station the signal is changed back to its original frequency by another frequency changer and fed to a display tube having long persistence. The operator compares the picture received with a photograph showing the site in its normal condition. If the operator suspects a deviation he may cause the signals to pass to a synchronized facsimile equipment to test whether a deviation from the normal picture is constant or variable, or if he wishes to give the deviation closer study or retain it for record purposes. In a modification the camera may be provided with an image splitting device of the kind which causes a stereo pair of images to be produced side by side. This may be done by an arrangement of mirrors or prisms. Each camera may have a tape recorder to transmit speech signals while the camera signals are not being received to avoid the possibility that a telephone operator may disconnect the line thinking it to be faulty. There may be a device at the central station which stores picture information at the site in its normal state and compares this with the signal from the camera, giving an alarm when a difference is detected. The store may consist of a photograph which is scanned by a synchronized camera, or it may be a record on tape or in a computer store.
