Title: Process for the production of refractory cased bricks
IPC: B28B23/00
Filed: 1966-06-29
Abstract: 1,144,027. Moulding refractory bricks. VEITSCHER MAGNESITWERKE-A.G. 29 June, 1966 [8 July, 1965], No. 29250/66. Heading B5A. [Also in Division F4] A method of making a metal-encased refractory brick having in addition a superposed layer of cardboard or like expansion material on at least one side comprises placing a metal coversheet 4 with a superimposed layer of cardboard 5 stuck thereto on a lower ram 2 in a mould 1, filling the mould with a predetermined quantity of loose refractory material 9, covering the material with a U-shaped metal cover 6, to one limb of which is stuck a layer 7 of cardboard, such that this composite limb seats in a recess 3 in the mould wall, covering the top of the mould with a plate 8 and raising the ram 2 to compress the material to form a brick. The passage of the ram upwardly does not crumple the layer 7 residing in the recess 3, a lip 13 thereof being undercut at 45 degrees. Various embodiments of bricks formed in this way are shown (Figs. 5-14). Thus the layer 7 may be inside or outside the limb 6, or may be encased in a U-shaped limb 6, while a limb (22) of casing 6 may be seated inside a U-shaped layer (20) of the material 7 which itself may be inside a U-shaped extra casing 21. The expansion material 7 may be formed only in ribs (31) in the side sheet at spaced points along the length of the brick. In all the embodiments, the layer 7 burns away when the brick is first used, thereby facilitating expansion of the brick itself when used.

Title: Improvements in or relating to the manufacture of flat glass
IPC: C03B17/00
Filed: 1959-08-28
Abstract: A tank contains a molten bath chemically inert to glass and means are provided for delivering a ribbon of glass to, and advancing it along the bath, local tubular control elements being arranged in spaced relation with a side of the bath, each of said control elements consisting of arms passing through and being axially adjustable in, the side wall of the tank containing the bath and an intermediate part lying lengthwise of the bath and connecting the arms, a fluid medium being passed through each element to vary the local temperature in the bath. The control elements permit the production of local temperature variations in the bath to control the direction of movement of the ribbon. In the form shown the ribbon 1c is fed between casting rolls on to the surface of an elongated metal bath maintained at a progressively decreasing temperature towards its exit end. The tank has a roof and the headspace is filled with an inert atmosphere. The control elements each comprise a U-shaped tube with parallel limbs 24 joined by a connecting portion 23 dipping in the bath. The limbs 24 are spaced by bridge members 46, 47. Flexible bellows 31 seal the apertures where they pass through the side walls of the tank. These limbs are individually adjustable vertically by screws 44 in elongated holes 43 in supporting plates 42 carried from a single plate 40 also vertically adjustable and secured in position by a clamping screw 39. The vertical adjustment varies the depth of immersion of the portion 23 in the bath 5. <PICT:0954974/C1/1> Adjustment in the direction of the arrow 25 is limited by collars 45 abutting the plates 42. Cold water is passed to tubular elements the adjustment of which determines the steering effect on the ribbon 1c. A gaseous heating medium may be passed through instead if required. Specifications 769,692 and 954,975 are referred to.

Abstract: 322,843. Avery, Ltd., W. & T., and Bradley, L. C. Oct. 16, 1928. Testing coins. - To prevent the insertion of cardboard discs or of undersized coins or discs, the slot is obstructed by a slide or slides 12 which are withdrawn bv the insertion of a correct coin 10. Iron discs of correct size passing the slides 12 are stopped by a magnet 17 which is pivoted at 18 and is provided with lugs 17<a> which swing into the path of the inserted disc. The apparatus is shown in sectional plan and elevation in Figs. 1 and 2 with the parts in their normal positions. Levers 11 pivoted at 11<a> pass through slots 12<a> in the slides 12 which are held in the obstructing position as shown by springs 13. Levers 15 pivoted at 16 have hooked ends 15b which normally lie in the path of the slides 12 and limit their opening movement. A coin of correct diameter passing between the levers 11 brings the ends 11<b> of the levers against set-pins 14 on short arms of the levers 15, so as to turn the levers 15 about their pivots and permit the coin to pass the slides 12. A cardboard disc will not exert sufficient pressure on the levers 11 to overcome the resistance of the springs 13.

Title: Improvements in or relating to the production of alkali metal silicates
IPC: C01B33/32
Filed: 1954-10-19
Abstract: Anhydrous alkali metal silicates having a Na2O : SiO2 ratio of above 1.8 : 1 but not exceeding 2.25 : 1 are formed by mixing an alkali metal silicate solution having a M2O : SiO2 ratio of 1 : 1 to 1 : 3.4 with an alkali metal hydroxide solution of 10-73 per cent strength in quantities calculated to produce a mixture having an M2O : SiO2 ratio of at least 3 : 1 and a total solids content, calculated as alkali metal oxide and silicon dioxide of less than 50 per cent, and evaporating the resultant mixture at 150-193 DEG  C., to provide a solids content more than 50 and less than 60 per cent and thereafter cooling to a temperature between 65 DEG  and 90 DEG  C., allowing the mass to set until crystallization is complete, separating the crystals, which may have a M2O : SiO2 ratio from 1.6 : 1 to 1.8 : 1, contacting them with alkali metal hydroxide solution of more than 25 per cent strength to increase the M2O : SiO2 ratio to above 1.8 : 1 but not over 2.25 : 1, agitating and finally drying, at 100 to 175 DEG  C. for example.  A product consisting mainly of sodium sesquisilicate with cocrystallized sodium hydroxide, in the form of small spheroidals of 2 to 5 mm. diameter may be obtained.  According to an example an aqueous solution of sodium silicate having an M2O : SiO2 ratio of 1 : 3.22 by weight and solids content of 38.8 per cent was mixed with 50 per cent strength caustic soda to provide a liquor having a Na2O : SiO2 ratio of 4.21 : 1.  The liquor was evaporated until the temperature is 156 DEG  to 158 DEG  C. and then cooled rapidly to 65 DEG  to 70 DEG  C. in 10 minutes with gentle stirring. Crystallization was allowed to occur and the mixture of crystals and mother liquor was thoroughly mixed to form a slurry which was delivered to a centrifuge and the crystals separated from the mother liquor.  The Na2O : SiO2 ratio of the so-formed crystals was 1.68 : 1 and this crystal mass is treated with 49.6 per cent NaOH in quantity sufficient to provide a 2 : 1 Na2O : SiO2 ratio after which the mass was heated to 110 DEG  C. to dry.  The invention is applicable to silicates of Li, Na, K, Cs and Rb.

The receptacle is constituted by a glass cylinder 5 clamped between a ring 7 and a base 2 by means of screws 7b and suitable gaskets 6, 8 to secure tightness. The bottom of the receptacle is formed by a diaphragm 4 clamped between the base 2 and a frame 3. The diaphragm passes between discs 9, 10, the disc 9 carrying an annular rim 11 guided in the base 2 while a connecting rod 12 through slots 14 in which passes a shaft 15 is secured to the discs. To the shaft is keyed an eccentric 17 co-operating with rollers 18 mounted in the rod 12.

In use, the cover is removed and the article placed on the hook 21, the receptacle being filled with water when the parts are reassembled. The shaft 15 is now turned so that the diaphragm takes up the position shown in dotted lines, when if the case leaks, bubbles of air will rise through the liquid to the vacuum above. To prevent the diaphragm being inadvertently returned and water getting inside the case, the shaft 15 is locked by a locking pin 27 on a lever 26 being urged by a spring 28 against an eccentric 29 on the shaft.
