Title: Anhydrous crystalline borate and process for producing same
Inventor: NIES NELSON PERRY
IPC: C01B35/10
Filed: 1955-08-31
Abstract: An anhydrous, crystalline sodium borate composition (B2O3:Na2O equals 3.7 to below 4 : 1) and comprising mainly sodum 1.4 borate (Na20.4B2O3) is prepared by moving a feed composition (preferably continuously) of B2O3, Na2O and H2O with a B2O3/Na2O molar ratio of 3.7 to below 4 through a heating zone to produce a fused anhydrous melt and cooling.  The mixture which preferably contains not more than 30 per cent by weight of water is preferably calcined before moving through the heating zone to remove the water of hydration. The cooling should cause complete solidification during a cooling time of an hour and the melt is removed from the heating zone in a form that the volume/surface ratio allows this cooling time. Suitable feed materials described are (a) sodium borate (B2O3/Na2O ratio less than 4) with boric acid or sodium 1.5 borate; (b) granular calcined borax containing not more than 2 mols. of water and granular boric acid; (c) crystalline sodium 1,2-borate pentahydrate and crystalline boric acid; (d) calcined sodium 1.5 borate and calcined 1.2 borate in a 1.3 to 1.9 to 1 ratio, with a water content of less than 30 per cent by weight; (e) the 1.5 borate may be produced in situ.  Sodium 1.5 borate is produced by (a) reacting sodium 1.2 borate with boric acid in a current of hot air; (b) tumbling granular borax and boric acid in molar proportions 1:6 in a calciner in a stream of air at 85-100 DEG  F.; increasing the temperature to evaporate water as fast as it is released and when reaction is complete evaporating to produce dry 1.5 borate; (c) dissolving boric acid and sodium 1.2 borate (e.g. calcined borax) in water and crystallizing 1.5 borate.

Title: Improvements in rotary heat-exchangers
IPC: F28D19/04
Filed: 1946-08-22
Abstract: 620,602. Regenerators &c. CORBITT, R. W., and POTTINGER, S. F. Aug. 22, 1946, No. 25147. [Class 64(i)] A rotary-drum heat exchanger includes a drum constructed in two concentric parts with poor thermal conductivity between them, the parts being maintained substantially at the temperatures of the adjacent stationary parts so that sealing between rotary and stationary parts is facilitated. The device comprises an outer casing 10 within which an inner casing 14 is mounted by flanges 14a engaging splines 17 on the outer casing, relative thermal expansion of the casings being thus possible. The flanges 14a are doubled and of such a shape that the outer flange is substantially at the temperature of the outer casing while the inner flange is at a higher temperature. The inner casing has axial openings 15, 16 at its ends and is divided into two spaces by a partition 18. The outer casing has radial openings 11, 12. Hot gas enters the opening 15, passes through apertures 19 in the inner casing, and leaves the outer casing through the opening 12, while the air to be heated enters at 11 and leaves the inner casing at 16. A rotatable drum structure surrounds the inner casing and comprises an inner drum 24 and an outer drum 23 secured to end rings 21, 22 and spaced apart radially so that they are thermally insulated from one another, the inner drum always being traversed by hot gas or heated air, and the outer drum by cooled gas or cold air. The sealing means between the rotary and stationary parts comprise piston rings 28, 29 and sealing strips 32, 33. On account of the twopart drum construction, the temperature differences at the seals are small and clearances may therefore be reduced. The drums contain rolls of wire gauze, (not shown), and rotate on rollers 25 mounted on the outer casing, one of the rings 21 being formed with rack teeth which are engaged by a pinion 27 to drive the drum assembly.

Title: Improvements in method and apparatus for forming hollow glass articles
IPC: C03B9/20
Filed: 1934-08-31
Abstract: 427,272. Glass manufacture. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Libbey Glass Manufacturing Co. ; Ashland Street, Toledo, Ohio, U.S.A.) Aug. 31, 1934, No. 25169. [Class 56] A method of making a hollow glass article consists in immersing a cooled gathering- plunger in a mass of molten glass until it becomes coated with a layer of chilled glass of predetermined thickness, and then withdrawing the blank so formed and blowing it to the desired shape. Apparatus for carrying out the method comprises a plunger c, Fig. 1, forming part of a head B which is movable vertically into and out of a furnace A. The head is carried at the lower end of a spindle E, suitable means being provided for lowering and raising the spindle and for rotating it during the blowing operation. A cut-off device F is provided to sever the trailing glass from the blank after it is withdrawn from the pool 1 of molten glass, and an air jet G is provided to blow the trailing glass to one side after it has been severed from the blank. A sectional finishing mould H, and a take-out device K, are also provided. In use, the glassworking head B is lowered to the position shown in Fig. 10 so that the plunger C is immersed in the molten glass 1 and the lower edge of a ring mould D, which forms part of the head, is brought close to the surface of the glass. Suction is applied to the interior of the ring mould D to draw glass into the mould to form the neck of a glass article, the mould cavity being suitably shaped to form a screw thread on the neck of the article if desired. Water is circulated through the interior of the plunger C in order to maintain it at the required temperature. The chilling of the glass causes a blank to form about the plunger C, and this blank is withdrawn from the pool of glass 1 as the head B is lifted, as shown in Fig. 11. The thickness of the wall of the blank is controlled by regulating the temperature of the plunger, the time it remains immersed in the glass, and the rate at which it is withdrawn from the glass. Soon after the blank has been raised, the plunger C is elevated in the head B, as shown in Fig. 13, to separate it from the blank, a puff of air is admitted to the blank to expand it slightly, and the trailing glass 4 is cut off by the severing device F and blown to one side. Next the head and the blank are set in rotation and the blank is enclosed by the finishing mould H, Fig. 14. After the blank has been blown to its finished shape, the ring mould is opened to release the neck of the finished article, and the plunger C is raised out of the mould.

Abstract: 821,556. Measuring rotor unbalance electrically. LOSENHAUSENWERK DUSSELDORFER MASCHINENBAU A.G. Aug. 25, 1956, No. 26053/56. Class 40 (1). [Also in Group XIX] In order to ensure that the compensation required by an unbalanced rotor should be effectable within a predetermined angle in two predetermined balancing planes, the unbalance is augmented by an additional amount in one or more compensating planes, all the unbalance quantities being measured electrically, the compensating unbalances being initially introduced as a voltage of variable phase and magnitude which is adjusted until the resultant out-ofbalance is shown on a C.R.O. as being within the predetermined angle in each balancing plane. As shown (Fig. 1), a crank-shaft 5 to be balanced by drilling the counterweights 11, 2<SP>1</SP>, 3<SP>1</SP>, 4<SP>1</SP>, is supported in spring bearings 6, 7 so that lateral vibrations are sensed by piezo-crystal pick-ups 12, 13. The signals from the pick-ups are fed across series potentiometers 14, 15 and combined in a ratio defined mathematically so that the voltage between the sliders 14<SP>1</SP>, 15<SP>1</SP> is indicative of the unbalance in plane 2 only. Auxiliary . voltages of the same frequency are obtained from generators 16, 17, rotating synchronously with the crank-shaft 5, the phase of these voltages being adjusted by rotating the field windings and indicated by pointers 19. These voltages are operated on in potentiometers 21-24 in ratios defined mathematically so that they represent additional unbalances in planes 1 and 4, and are then algebraically added to the previous signal representing the unbalance in plane 2, the resultant signal being fed through an amplifier 25, and phase-sensitive rectifiers 26, 27 to a C.R.O. 31 where the position of the spot on a radially calibrated screen indicates the magnitude and angular position of the required compensation in plane 2. The magnitude and phase of the auxiliary voltages from the generators 16, 17 are adjusted until the spot on the C.R.O. screen appears within the angle in plane 2 wherein drilling is allowable. The process is repeated for plane 3, so that the amount and position of the compensation in all four planes 1, 2, 3, 4 is known. An apparatus is described which enables the mathematical ratios to be obtained mechanically.
