Filed: 1948-06-29
Abstract: 648,484. Photo-electric turbidity detectors. PERMUTIT CO., Ltd. (Permutit Co.). June 29, 1948, No. 17468. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 22, 1949.] [Class 40 (iii)] In a photo-electric turbidity detector the liquid is caused to form a sheet, the flat sides of which are unconfined and through which the beam of light to the photo-cell passes. In this way deposition on the sides of the container, with consequent falsifying of the turbidity values is avoided. As shown, liquid enters the cruciform pipe 13 through a narrower pipe 25. This latter pipe is circular in section at its top but is flattened at its lower end. A section of the lower end of the pipe viewed in the direction of the arrows 2-2 is shown in Fig. 2. The flat sides of the pipe are cut away at 29, and through this gap the beam of light passes from the source 37 to photo-cell 39, lenses 20 being mounted at each end of the arms of the cross. Filler pieces 27 mounted in the rectangular outlet assist in shaping the water flow.

Title: Vitreous enamel-coated ferrous article and method of making the same
IPC: C03C3/089
Filed: 1962-05-09
Abstract: To improve the adherence of a vitreous enamel to a ferrous base, the base is coated with nickel-alkali metal oxide crystalline particles in an amount greater than 0.05 grams of dry particles per square foot of base, the enamel being applied to either the coated or uncoated side. The particles may be crystallized on a nucleus of nickelous oxide. Preferably, a nickel-lithium oxide is used, the particles containing lithium oxide in an amount from 0.5 to 12.0% by weight. The nickelous oxide nucleus may comprise 5 to 80% by weight of the particles. The sand-blasted base of steel is coated with an aqueous slurry of the particles in the following mixture, in weight per cent; the particles 5-30; silica (as diluting material) 0-40; bentonite 0-10; sodium carbonate 0-1%; sodium nitrite 0-1%; water, balance. The water is evaporated and the enamel sprayed on and fired. Examples of enamels used are (1) silica 50.8; sodium oxide 19.8; calcium oxide 5.9; aluminium oxide 5.5; boron oxide 18.8; cobalt oxide 0.5; and (2) silica 56.0; feldspar 15.0; borax 12.0; soda ash 7.0; sodium nitrite 5.0; fluorspar 5.0. Both were fired at 1580 DEG  F. for 8 minutes. Nickel-alkali metal oxide crystals are prepared as follows: sodium or potassium compounds being possible alternatives to the preferred lithium compounds.  A nickel compound such as nickelous nitrate is heated to about 280 DEG  F. to melt the same and lithium carbonate dissolved therein.  The mixture is heated to 400 DEG  to 600 DEG  F. for a period of 1 to 10 hours to decompose the nitrates and carbonates and to nucleate the precipitation of fine nickel-lithium oxide crystals, containing, based on the nickel oxide, 0.5 to 12% alkali metal oxide.  Heating is then at 1030 DEG  to 1080 DEG  F. for a period of 1 to 10 hours to obtain crystal growth to the required particle size.  Alternatively, the nucleation may be on nickelous oxide particles, about 5 to 80% of finely divided particles being added to the nickelous nitrate and lithium carbonate molten mixture and the same heating cycle used. In a further method, a mixture of nickelous oxide and lithium carbonate is heated to 1200 DEG  to 1600 DEG  F., preferably about 1480 DEG  F., the lithium carbonate melting at a lower temperature so that part of the lithium oxide will be volatized, but part diffuses into the nickelous oxide to form the nickel-lithium oxide crystal structure.  Particular examples are given in which 4 parts of the lithium compound are used to 96 of the nickel compound and 2 to 97.5, the rest impurities.

Title: Process and arrangement of apparatus for the purification of coke
IPC: C10L9/02
Filed: 1935-06-21
Abstract: Coke lumps produced from coal without additional materials are treated with dry gaseous chlorine or hydrochloric acid or a mixture of the two immediately after the coke has left the oven and before it has lost its heat.  At the end of this treatment hydrofluoric acid may be used as an additional gaseous reagent whereby residual silica may be removed at e.g. 200 DEG  C. and fluosilicic acid or its salts obtained.  Volatile compounds of iron, aluminium and silicon are expelled at the higher temperatures of 900--1000 DEG  C. and condensed.  Sulphur in the form of sulphur chloride is also obtained, a more thorough expulsion of the sulphur occurring at a lower range of temperatures.  In an example from 1000 kg. of washed coke containing 10 per cent of ash (consisting of about 5 per cent SiO2, 2,5 per cent Al2O3 and 2,5 per cent Fe2O3), and ,9 per cent of sulphur, the treatment with 213 kg. of chlorine produces 50 kg. FeCl3, 65 kg. AlCl3, 142 kg SiCl4, and 6,3 kg. S2Cl2.

Title: Electromagnetic interrupters for the intermittent illumination of electric lamps
IPC: H01H51/32
Filed: 1924-07-26
Abstract: 238,358. British Thomson-Houston Co., Ltd., (General Electric Co.). July 26, 1924. Electromagnetic interrupters.- A continuous slowacting interrupter for flashing lamps on buoys, the operation of which is unaffected by wave-motion, comprises a rocking armature 20, the ends of which are attracted by the poles of a U-shaped electromagnet, carried on a central pivot 19 so as to be mechanically balanced on a non-magnetic lever 17 itself carried on a fixed pivot 16 and mechanically balanced by the weight 31 and the screw adjustment 32. The armature is normally drawn away from the poles by a spring 22, so that the lever 17 rests against an adjustable stop 25, and a contact blade 27 bears against the contact 26. To provide for a slow time-period of interruption the magnetic circuit of the electromagnet is made of low permeability and a thick conducting sleeve or thick closed coil is arranged round each core. This gives a long time constant to the electromagnet, and further to slow down the rate of interruption one of the poles has secured to it a channel-shaped pole-piece 35 constituting a double pole. The stop 25 is adjusted so that the end of the armature lies midway between the poles of the double pole-piece, and, with this adjustment, the armature is not attracted at that end until the maximum flux has been built up in the electromagnet. The circuit arrangements are shown in Fig. 4, the lamp 41 and the electromagnet being supplied separately from the battery 39 each through the make-and-break contact 27.

A packaging machine has at three separate stations, means for making block bottomed bags in expanded form, means for filling the bags and means for evacuating the bags; the stations being connected by conveying means which conveys the bags in expanded form and also means for closing the evacuated bags. A bag formed from material from a roll 18 folded about a mandrel 1, has a carton blank from a stack 19 folded about it. The apparatus for doing this may be as described in Specification 258,564. The bags and cartons are removed from the mandrels at 3 and stood upright in holders 4 of a wheel 5 which conveys them below a filling unit 6 and then to a position 7. During this latter motion the bags are agitated to settle the contents. At 7 each bag is transferred to a closing wheel 9 which seals the mouth of the bag, except for an air exit opening, during its rotation to convey the bag to a device 10 which transfers it to an evacuating chamber 11 on a rotary drum 12 which may be of the form described in Specification 884,239. The bag, after having been evacuated and sealed, is transferred by means 13 back to the closing wheel 9 where the top of the bag is folded over and the carton closed and sealed and transferred to a delivery table 16 by a conveyer 15. In a modified form of apparatus the chambers 11 are replaced by evacuating tubes which pass through the mouth of the bags. The stations may be arranged along a single conveyer. 916,886.

Title: Improvements in cyclic polymers of dimethyl silanone and in methods of preparing the same
IPC: C07F7/21
Filed: 1943-10-29
Abstract: Polymers of dimethyl silanone having the formula [(CH3)2SiO]x, where x is at least 3 and is not more than 10 are prepared by hydrolysing a dimethyl silicon dihalide, separating the hydrolysis products from the hydrolysis medium and separating from the hydrolysis products any products which distil over at temperatures below 160 DEG  C. at 20 mms. pressure.  The remaining high boiling fraction which is substantially non-volatile at 200 DEG  C. at 1 mm. pressure is subjected to a temperature of between 350-450 DEG  C. at 760 mms. pressure to convert the high boiling polymers to low boiling polymers of the formula given above.  The material so obtained is specially suitable for use as a high temperature lubricant as is described in Specification 586,189.  In an example, dimethyldichlorosilane is slowly added to water at a low temperature, the oily product separated and fractionally distilled.  A series of polymers from the trimer to the hexamer are separated.  The residue from the fractional distillation which was substantially non-volatile at 200 DEG  C. and 1 mm. pressure was heated up to 350 DEG  C. at ordinary pressure and an inert gas passed through the apparatus.  The products thus obtained were again fractionally distilled to separate the low-boiling distillation products which had been formed. Specification 542,655 also is referred to.

Title: Handheld photoelectric appliance for testing liquids
IPC: G01N33/49
Filed: 1975-05-01
Abstract: 1486505 Photo-electric testing of liquids COMPUR-WERK GmbH & CO 1 May 1975 [4 June 1974] 18125/75 Heading G1A The invention provides a hand-held photo-electric analyzer for making absorption measurements on liquids. In Fig. I the liquid, in a square section cuvette, is placed in aperture 50 and light is transmitted through it from a lamp 16, Fig. 4, to a detector 32. The measuring circuitry is initially zeroed without the cuvette so that the needle 38a of a meter lies opposite a calibration mark 46, and after inserting the cuvette the needle is returned to this mark by thumb-wheel 20 which operates a wedge filter; the absorption is then read off a scale on the thumb-wheel. The scale may be calibrated in terms of a particular measurement, e.g. the amount of haemoglobin in blood. To zero the analyzer, switch 18 of Fig. 1 is pressed to connect up batteries 14, and the thumbwheel is turned to an extreme position where the thickest portions of the arcuate wedge filter 22, Fig. 4, it carries lies between the lamp and detector 32. By pressing a switch 44, circuits 40 and 42 equalize the signals produced by detector 32 and a reference detector 34, and the meter needle moves to the central position. During this zeroing the cuvette is absent, and aperture 50 is closed by a spring loaded flap. Insertion of the cuvette reduces the light falling on detector 32, and balance is restored by turning the thumb-wheel. A filter 30 determines the wavelengths at which the measurement is made.
