A guide 4 is formed within tube 1 and has an opening 7 within which tube 6 is slidable and openings 5 providing communication between the parts of tube 1 on -either side of the guide. The tube 6 has a portion 14 of enlarged diameter fitted with a socket 16 closable by a plug 17. The portion 14 extends through a guide tube 13 at the rear of tube 1 and, when the catheter is not in use, exits therefrom through a slanted opening 15. A slot 19 extends from opening 15 to the end of guide tube 13 and portion 14 is positioned therein when the catheter is in use, socket 16 abutting the end of guide tube 13 to retain the catheter in its buckled position. Irrigation fluid can be introduced into the body cavity through tube 6 which opens at 8 in tip 2. Longitudinal passages 9 are provided in tip 2 for passage of fluid from the body cavity into tube 1 prior to buckling of tube 1, this initial fluid flow indicating correct positioning of the catheter wthin the cavity.

[Also in Division F3] In order to align discontinuous elongated metallic heat conductors 6 within a viscous propellent matrix 5, the matrix is passed through a passageway 1 in which transverse alignment means 2, 3, 4 are arranged. Such means may comprise groups of parallel members 2a, 3a, 4a, each group being displaced with relation to the others. The members 2a &c. may be of wire or of bands arranged edge-on to the flow. Alignment means in the form of a spiral band and a screen may also be used, or a number of screens of decreasing mesh size. The heat conductors are aligned in the direction of flame propagation and increase the burning rate in this direction. Alternatively the alignment means may be moved relatively to a stationary container holding the matrix. The metallic heat conductors may be in the form of short wires or flat strips, preferably ¢-inch or less in length, and may be of Al, Mg, Be, Zr, Ti, Ag, Cu, or alloys thereof. A coating of a self-oxidant or non- oxidant composition may be applied to the metal conductors. In examples the viscous propellent mixture comprises a polybutadiene binder, ammonium perchlorate, aluminium powder, a burning rate catalyst, and elongated aluminium heat conductors; the polybutadiene may be carboxy-terminated. An inhibitor casing may be applied to the matrix without disturbing the orientation of the heat conductors by various procedures which prevent relative movement between the matrix and the casing (see Division F3). The propellent grain may be cured by heating under pressure.

Abstract: <PICT:0965294/C1/1> Raw refractory material, e.g. magnesite or dolomite, is sintered or dead-burned, together with not more than 2.5% by weight of a sintering agent by means of the combustion of a fuel, the air-supply for which is oxygen-enriched. Preferably the proportion of oxygen in the air is at least 22% by volume.  The combustion air may be enriched in situ by supplying oxygen to the combustion zone.  Specified raw refractory materials are a slurry of magnesium hydroxide precipitated from sea-water, pressed briquettes of magnesite concentrates from froth-flotation of magnesite ores, or crushed granules of high-purity dolomitic limestone. The sintering agent may be, e.g., silica, alumina, or iron oxide.  Sintering may be carried out in any conventional kiln.  In one embodiment (Fig. 1), a fuel such as powdered coal, fuel oil or natural gas is carried, with air, via non-rotating pipe 11 into rotating kiln 10, containing raw refractory material, and sintering agent and ignited, forming flame 13.  Oxygen is fed in through water-cooled lance 14, or alternatively, may be mixed with the primary air supply. The relative supply rates of fuel and oxygen-enriched air are such that the fuel is just sufficient to utilize all the available oxygen.  The sintered refractories produced have low porosity, high melting point and less than 2.5% by weight of impurities such as Fe2O3, Al2O3 and SiO2.

A braking system for railway vehicles comprises two fluid pressure actuators 10 each of which is arranged to act through a separate pivoted lever 12 on braking means 29, each lever 12 being adapted to pivot alternatively about two points 15, 30 in its length, and independent handbrake means 13 adapted to act on the brakes through the pivoted levers, selector means common to both levers being provided whereby the pivot points of the levers 12 may be selected. The common selector means comprise an operating lever 26, a cam 23 and a vertical shaft 21 on which is a transverse strip 20. The pivot point 30 for each lever 12 is a pin engaging slots in a fixed part of the frame and the pivot point 15 is a pin carried in a fulcrum strut 16, one end 17 of which can be engaged with an abutment 18 on the vehicle frame and the other end 19 of which is engaged by the transverse strip 20. When the fulcrum struts 16 have their ends 17 on the abutments 18, as shown, and either the actuators 10 or hand wheels 14 (Fig. 2, not shown) are operated, the levers 12 pivot about the pins 15 and transmit a force through the links 29 to operate the brakes. The lever ratio is increased by transferring the pivot points of the levers 12 from 15 to 30. This is done by moving the operating lever 26 from the tare position 27, where it is shown, to the laden position 28, so rotating a cross shaft 24 which carries the cam 23 whereby to cause the cam to depress the vertical shaft 21, raising the ends 17 of the fulcrum struts 16 clear of their abutments 18 so that the pins 15 can no longer function as pivots for the levers 12.
