The invention relates to sliding windows of the kind having a catch bar 14 which extends across the window transverse to the direction of sliding movement, is pivotally attached to a frame or to an edge-rail forming part of the window for movement about an axis extending lengthwise of the bar and has at one or each end a catch member which makes holding engagement with an abutment 4 on a fixed outer frame member, the bar also having a radial projection providing means by which such pivotal movement may be effected by manual operation. According to the invention, the catch bar has a section of V-form comprising two radially extending limbs and a rounded base, the latter either being received within and held by a bearing surface on the frame or rail or fitting over and bearing on a rounded head on the frame or tail and the limbs being at such an angle one to the other than one limb 16 which constitutes the projection projects outwardly from the face of the window, and the other limb 17 which provides or carries the catch member extends in the general direction of sliding movement of the window and is 'movable by pivoting of the bar. In the arrangement according to Fig. 1, in which a window pane 1 is slidable in a fixed frame 3, the pane is provided with a top bar 2 having a longitudinally extending groove 8 bounded on one side by a wall 9 having a beaded edge 10 which latter serves to pivot the catch bar 14, the limb 16 of which serves as a finger grip and the other limb 17 of which makes latching engagement at its ends with the abutment 4 attached to the fixed frame. A step 12 formed on the top bar 2 provides a second fixed finger grip. The catch bar is biased to latching position by a coil spring located in a cut away portion of the bead 10. In another arrangement, Fig. 5, the bead 10 is replaced by a retaining wall 11 a of the top bar. The catch bar which is provided with springs 20 is also provided in the region of its centre portion with a finger grip of hard plastics. The invention is applicable to rising windows and to horizontally slidable windows. Specification 530,258 is referred to.

Title: Treatment of pyrochlore
Inventor: BURKIN ALFRED RICHARD
IPC: C22B34/24
Filed: 1960-10-17
Abstract: Niobium and tantalum values are extracted from pyrochlore by thoroughly mixing and roasting the ore with a limited amount of sodium or potassium hydroxide so that the ore forms a soft friable mass and leaves no separate molten alkali phase when the roasting is terminated, the metal values then are extracted with hydrochloric acid.  The roasting may be carried out in a single stage at a temperature above 350 DEG  C., or in two stages, the first at 350-500 DEG  C., the second at above 500 DEG  C.  A little water is preferably present at the beginning of the roasting stage. The roasted product may be added to boiling hydrochloric acid when virtually all the niobate and tantalate dissolves. Any precipitate forming from this solution is redissolved by the addition of water. Calcium salts or oxide or alkali metal chlorides, may be added to the roast.

Abstract: 468,885. Spray-carburetters ; vaporizers. KANE, F. A. Dec. 5, 1935, No. 35768/36. Convention date, Dec. 12, 1934. Divided out of 467,089. [Class 7 (iii)] [Also in Group XI] A method of forming a combustible mixture for use in internal-combustion engines or burners consists in passing liquid or semi-liquid fuel through a conduit formed by overlapping Venturi tubes, one or more of which has serrated terminal edges, and introducing air or air mixed with products of combustion, through the gaps between the tubes. As shown in Fig. 1, fuel is sprayed from a nozzle 50 into a series of overlapping Venturi tubes 32 . . 38 some or all of which have serrated ends. Air, which may be heated, enters from an inlet 30 through the gaps 39, 40 between the Venturi tubes at one end, whereas cold air enters the remaining gaps 41 . . . 44 from an inlet 47 separated from the inlet 30 by a partition 45. The air inlets are controlled by interconnected valves 48, 49. As shown, the nozzle comprises a serrated or slotted funnel but its edge may be plain or the fuel may be sprayed through the space 65, Fig. 14 between concentric funnels 63, 64, an air passage 68 being provided in the inner funnel. Air may be supplied to the Venturi tubes through a single inlet and the partition omitted. Opposed fuel nozzles may discharge into opposed Venturi tubes set at right angles to the main Venturi tubes, an air port between the opposed tubes serving to assist the deflection of the fuel into the main tube. The largest Venturi tube may open into a bulbous chamber arranged to create eddies to mix the fuel and air further. Heated air may be drawn from a jacket surrounding the exhaust pipe of an internal-combustion engine. In the form shown in Fig. 17, air and fuel are drawn through the tubes by a fan 94 and part of the mixture is led by a pipe 97 to be mixed with air in a chamber 101 and burnt in a chamber 103, the hot products passing through apertures 107 in a partition 108 behind the fuel nozzle. Further air is admitted through a pipe 105. In another form, a blower 115, Fig. 19, supplies cold air through a conduit 118, and air to be heated through a conduit 117 and tangential ports into a chamber 121 where it mixes with the products of combustion formed by igniting a mixture of fuel supplied through a nozzle 125 and air drawn through a space 128. The fuel.and air burn in a funnel 124 and then mix with air drawn through ports 130. Specification 467,089 is referred to.
