Filed: 1925-04-04
Abstract: 246,186. Universal Rubber Paviors (Manchester 1923). Ltd., and Brown, A. E. April 4, 1925. Compositions containing bituminous materials and clay.-Clay is ground to a state of fineness that 95-98 per cent will pass through a sieve having 200 meshes to the linear inch, hygroscopic water is removed from the clay by heat, and the product is mixed in proportions up to 55 per cent or upwards with bitumen &c. at a moderate temperature, to produce a composition suitable for use in road making and for other purposes. Preferably the clay is dried prior to or during grinding, by heating to 300-400‹ C., although temperatures of 105‹ C upwards are sufficient, to facilitate grinding, and this is mixed with bitumen &c. in a slow-running mixer at a temperature of 80-100‹ C. The clay ground to the necessary fineness may be dried during mixing with the bitumen, by employing a temperature of 'at least 105‹ C., preferably 175‹-180‹ C. The consistency of the product may be varied by the addition of oil flux.

Abstract: 686,676. Glazing. BYRON HORTICULTURAL ENGINEERING, Ltd. Sept. 20, 1950 [June 21, 1949], No. 16481/49. Class 20(iii) In a glazing means comprising spaced glazing bars 1, usually of T-section, with panes 14, 15 attached thereto by glazing clips 9 so that the side marginal edges ot the glass overlaps parts 8 of the bars and the panes are disposed end to end, with the respective upper and lower edges overlapped, and connected together by the clips, each glazing bar has a longitudinal slideway 6, 7, which captively engages a slide part 10 of a clip to attach the clip to the bar, and each clip has one or more lateral parts 12 to engage the outer face of a pair of overlapping panes and another part 13 extending therefrom for engaging the underside edge of an outer pane. Projecting from each side of the outer edge of the web 2 of the glazing bar is a rib 3 of substantially semi-circular cross section with the curved face 5 outermost and the underface 4 grooved at 6 and chamfered. The slide part 10 of the clip 9 is substantially rigid but slightly springy with the forward part preferably of arcuate form, the concave side being nearest the web 2. The clip is applied by inserting the near edge of the part 10 in the groove 7 and springing the front edge over the chamfer into the groove 6, and then sliding the clip to the required position and tightening it, if desired, by partly flattening the arcuate part of slide 10. The clip may be removed to repair or replace the glass by forcing the slide part 10 away from the web 2, e.g. with a screw-driver. The clips shown in Fig. 4 have extensions 16 which cover the marginal edges of the glass and are of such length that the ends of consecutive clips abut to give added support. When the glass on opposite sides of the bar is to be in different planes the bar is designed with its cross webs in the desired planes, or angle section bars are connected together in the desired relation to form the bar.

Title: Improvements in and relating to refining or alloying of metals
IPC: C22C1/02
Filed: 1936-06-19
Abstract: In a method of introducing alkali or alkaline earth metals into a bath of molten metal for alloying or purifying, the alkali &c. metal is formed into an elongated core which is surrounded by a closely fitting tube consisting of the metal of the bath or of fluxes or alloying ingredients for the metal of the bath; a piece of the required length is cut from the filled tube and added to the molten metal.  The ends of the tube may be closed by crimping, and the tube may be flexible and coiled.  The cores and sheaths may be made by extrusion.  For example calcium may be heated in an inert or reducing atmosphere and extruded into a tube of copper, which may be heated, or of an iron or steel alloy such as one containing chromium or vanadium; or an extruded rod of calcium may be drawn through molten lead at such a temperature that lead congeals on its surface.  In some cases the alkali &c. metal may be extruded into a tube of a slagforming material such as silica or alumina.  The sheathed metal may be held beneath the surface of molten metal such as iron &c. by means of a heavy iron rod; or a long length may be gradually introduced as consumed; or short pieces may be propelled into the bath by means of an air gun or the like.
