Title: Process and apparatus for the surface treatment of glass and like vitreous materials
IPC: C03B27/03
Filed: 1966-03-28
Abstract: <PICT:1118656/C1/1> <PICT:1118656/C1/2> The surface of a glass article is treated by electrically connecting at least one part of the article to one pole of a D.C. supply; placing at least one other part in contact with a medium containing ions or ionizable atoms; connecting the medium to the other D.C. pole; causing the zone(s) of contact between medium and article to move across the surface of the article.  The article is maintained at a temperature to render it electrically conductive. The polarities of the article and the medium are such that the ions enter the article from the medium.  In this way, ions in the glass may be displaced by different ions.  Thus, the surface of the article may be brought into a state of compression. One or both sides of a glass sheet, or the whole article, including edges, may be treated.  The process may be performed continuously. The temperature of the glass may be controlled by contacting with a hot gas or liquid.  The medium may be, e.g. a molten metal, an amalgam, an electrolyte solution or a liquid salt.  For example, for soda-lime glass treatment, an anode compartment may contain a molten potassium salt.  Apparatus comprises two compartments, each containing a polarized bath, and means for moving the article through each of the compartments in turn.  Several embodiments are described. A compartment may take the form of a shallow pan with a slot through which one sheet passes (Fig. 4), pads of fibrous materials in a bath (Fig. 7), rollers patly immersed in a bath (Fig. 7), or perforated rollers filled with fibrous material with means for feeding bath material to the interior of a roller (Fig. 9, not shown).

Patent GB-717277-A (GB)
Title: Improvements in methods of separating phosphate ions from iron ions
IPC: C01B25/234
Filed: 1952-05-30
Abstract: An aqueous solution of phosphate ions free from iron ions is prepared from a solution containing phosphate ions and iron ions by the following steps: precipitation of iron hydroxide in alkaline solution; precipitation of phosphate ions in the filtrate free from halogen ions in an acid solution by adding bismuth salts; separating the precipitated bismuth phosphate; dissolving this precipitate in aqueous hydrogen halogen acid; precipitation of bismuth ions either as the sulphide by the addition of hydrogen sulphide or as bismuthyl salt by hydrolysis, separation of the precipitate and, if necessary, evaporation of the filtrate to free the phosphoric acid solution from unwanted volatile acids.  The process is particularly applicable to the production of a radioactive P32 preparation from phosphorus iron which has been bombarded by deuterons.  This iron is decomposed, for example by an alkaline oxidation mixture of solid sodium hydroxide and sodium nitrate, whereafter it is lixiviated and filtered thereby removing the iron as hydroxide together with radioactive cobalt and manganese.

In a thermopile consisting of a plurality of thermocouples each comprising a pair of legs of different conductivity types joined by heat - conducting members, all the heatconducting members of the individual couples are combined to form a coherent block while being electrically insulated one from another. The conducting members are so joined that electrically adjacent legs of adjacent couples extend from the block in parallel pairs in order that they may be connected by further heat-conducting members. Fig. 2 shows an assembly of two couples n 1 , P 1  and n 2 , p 2 , the heat-conducting blocks 1 and 2 at e.g. their cold junctions being joined by a thin layer of insulating material 6, and the couples being serially connected by a further conducting block 4. This construction may be extended to four couples, Fig. 3 (not shown), or in a modification in which P 1  and n 2  are mounted on the ends of the conducting blocks rather than the sides, the pairs of couples may be stacked to any desired extent, Fig. 5 (not shown). The insulating material between the conducting blocks may be restricted to small areas of the blocks so as to leave passages for the flow of fluid to conduct heat to or from the blocks.

Title: Improvements relating to gyroscopic turn indicators
IPC: G01C19/44
Filed: 1929-05-03
Abstract: 331,627. Brown, S. G. May 3, 1929. Gyroscopic apparatus.-A turn indicator for aircraft, &c. comprises a gyrowheel having its axis normally horizontal and suspended with three degrees of freedom, in combination with resilient mea.ns for restraining tilting of the gyro-wheel axis in either direction about a horizontal axis and yielding means opposing movement of the gyro-wheel axis about a vertical axis. In one form, Fig. 2, the gyrowheel 10 is carried in a frame 12 supported in neutral equilibrium on horizontal pivots 14 within a frame 16 which is mounted on vertical pivots 18 in a fixed frame 26. Tilting of the frame 12 about the pivots 14 is restrained by a spring 20 having one end attached to the frame 12 and the other end connected by a cord 29 to a winch 32 which can be turned by a finger-piece 34 to vary the tension of the spring 20. Movement of the frame 16 about the axis 18 is restrained by the friction between a pad 22 carried bv the frame 16 and the surface 24 of the frame 16. The surface 24 is preferably part of a cylinder having a radius greater than the distance 18-24, so that the frictional resistance increases with increasing amplitude of movement. The pad 22 is urged against the surface 24 by an adjustable spring 46. An index plate 50 carried by one of the pivots 14 co-operates with a dial 52 fixed to the frame 16. In another form, Figs. 6 and 7, the pivot axis 18 is at one end of the frame 16 and springs 66 are provided to centralize this frame, the friction between the members 22, 24 being in this case the same in all positions of the frame. The dial 52 is mounted on the fixed frame 26 and the index plate 50 is fixed to a spindle 70 journaled in the fixed frame. This spindle carries a gear wheel 72 gearing with a wheel 74 on the pivot 14, and the axis 18 passes through the point at which these wheels mesh.

Abstract: 404,854. Hinges. SHATTOCK, J. R., 25, Theobald's Road, London. May 12, 1933, No. 13922. [Class 65 (ii).] Pivoting adjustments.-A door pivot comprises a pin held against rotation in one member and bearing in a socket in the other, the pin having one or more depressions or longitudinal grooves and being engaged by an adjustable spring- pressed detent, sliding in a housing transverse to the axis of the socket, to hold the door against light pressure in one or more predetermined positions, one of which may be the closed position in the case of a swing door to prevent the door from being slightly opened by wind without the necessity of using a strong closing spring. Means may be provided to retract the pin axially from the socket when it is required to remove the door. In the form shown, for a swing door opening in both directions, the pin 1 is held against rotation in a socket 9 on the lintel and bears in a socket 2 in the top of the door, which is shown closed ; the pin is longitudinally slidable in the socket 9, to facilitate mounting of the door in its frame, by a lever 11 pivoted at 12 in the frame and having one end engaging the pin 1 and the other actuated by a screw 14 accessible when the door is open. A horizontal cylindrical housing 17 communicates with the bore of the socket 2 in the door by a hole in the wall of the socket, and a spring- pressed plunger 19 in the housing 17 carries a roller 21, or has a hardened nose, which projects through the hole into the socket to engage either of two diametrically-opposed grooves 15 in the pivot pin 1 to hold the door open when opened in either direction. The outer end of the spring bears against an adjustable bush 23 screw-threaded into the end of the housing 17 and serving as a guide for the plunger stem. The pin may be prevented from rotating in the socket 9 by ribs in the socket engaging the grooves 15 in the pin. A groove similar to 15 may be provided to retain the door closed, either in addition to or in place of the grooves shown ; for a door opening in one direction only one of the grooves 15 is dispensed with ; additional grooves may be provided to hold a door open at other angles. When applied to a door opening only in one direction, the housing 17 may be arranged at an angle to the plane of the door and may project from the socket 2 in a direction away from the door-post, so that the bush 23 is accessible at one side of the door.

A plate fixed across the bottom of the casing has a central bevelled portion i<1> forming an indicator to facilitate positioning the device. To avoid damage to the numbers, the wheels b are arranged to project slightly less than the depth of their numbers below the lower face of the plunger a. A pin 6, resting in opposite apertures in the casing and secured in position by a spring band g, passes through an elongated hole a<3> in the plunger, thus limiting the depth of the impression. The lower part of the plunger is cut away to clear the indicator plate.
Patent GB-168037-A (GB)
Title: Improvements in door latches
IPC: E05B63/20
Filed: 1921-05-18
Abstract: 168,037. Beauchamp, H. Aug. 18, 1920, [Convention date]. Turn-bolt door fastenings; striking- plates for latches.-In a latch for carriage doors &c., the latchbolt is pivoted and holds the trigger that releases it when the door is slammed out of contact with the striking- plate to avoid undue wear. The latch-bolt 5 is provided with bosses 6 fitting into circular holes in the casing 4 and cover-plate 8, and can be manually operated to open the door by handles secured to a square spindle fitting in the hole 9. A trigger 22, sliding in guides 18 and pressed outwards by a spring 20, has a pawl 24 engaging a notch 25 in the tail of the latch-bolt, to hold this in the half-lock position shown in Fig. III. When the door is closed, the bevelled end of the latch-bolt 5 contacts with the bevelled advanced part 30 of the striking-plate, disengaging the undercut faces of the pawl 24 and notch 25. As the door moves further, the trigger 22, now free to move, is pressed inwards by the bevelled part 23 of the striking-plate, enabling the spring- pressed follower 12 to move forward by turning the latch-bolt on its pivot to its operative position. The shoulder 15 on the follower engages the shoulder 16 on the latch-bolt, and the camshaped faces 27, 28 on the tail of the bolt hold the trigger out of contact with the striking-plate when the bolt is shot. The end of the tail of the bolt rides over the end of the pawl 24, forming additional means for holding the latch-bolt in its operative position in the slot 31 of the striking- plate. The lock can be fitted to right or lefthanded doors and the striking-plate made to correspond by inverting it. Fig. V shows a curved striking-plate for use when the latch is used for swinging doors, the upper part of the slot 31 being widened to allow the bolt to fall when the door is still moving. Fig. VI shows the latch modified for use with a sliding door, the latchbolt being L-shaped or T-shaped. In this case the latch-bolt is not held in the half-back position, but in the completely withdrawn position, as shown by the broken lines, and the engaging faces of the pawl 24 and notch 25 are not undercut, there being no necessity to hold the trigger out of contact with the striking-plate when the door is closed since no swinging movement would occur to wear out the end of the trigger.
