Title: Production of phosphorus-containing esters
IPC: C07F9/40
Filed: 1976-04-13
Abstract: Phosphorus-containing esters of the formula <IMAGE>  in which   X is an alkyl group having 1 to 3 carbon atoms, an aryl group or an alkoxy group having 3 to 6 carbon atoms,   Y is an alkoxy group having 3 to 6 carbon atoms and Z is a hydrogen atom, an alkyl group having 1 to 3 carbon atoms or an aryl group, are prepared by reacting corresponding phosphorus halogen compounds with aliphatic alcohols having 3-6 carbon atoms. The phosphorus-containing esters containing P-H bonds are valuable starting materials for flameproofing agents for polyesters, polyurethanes and polyacrylonitrile. As a consequence of their high purity, they are particularly suitable as reaction components for reactions catalysed by free-radical formers.
Patent GB-893164-A (GB)
Title: Improvements in a process for the continuous production of aluminium nitride
IPC: C01B21/072
Filed: 1958-05-12
Abstract: <PICT:0893164/III/1> Aluminium nitride is continuously produced by passing aggregates of a mixture of aluminium oxide and carbon with a calcium aluminate binder under gravity down an upright heat-treatment zone maintained at 1750 DEG  C. or below, countercurrent to nitrogen, and collecting alumina condensates containing calcium and carbon outside the zone in an adjoining, communicating condensation region maintained at 1200 DEG -1400 DEG C.  The N2 flow is sufficient to prevent local melting or sintering of the aggregates, and continuously sweeps gases from the heat-treatment zone.  The pellets entering the furnace at 1, pass through preheating section 2, to graphite columns 13, down which they pass against N2 entering at 7 and leaving at 9.  Columns 13, insulated by aluminium nitride sheaths 12, are provided at their heads with condensation chambers 3.  The nitriding section 4 of the columns is heated externally, out of contact with the pellets, by electric resistors 11 arranged in sets, each set being electrically independent from the others, allowing temperature control down the columns.  Pellets leaving the nitriding section pass down through cooling section 5 and are removed from the base of the columns by a continuous extraction device 6 enclosed in a gas-tight chamber.

[Class 114.] Variable-pitch air-screws of the kind wherein the pitch is varied in accordance with the longitudinal displacement of the boss on the driving shaft are provided with an additional driving connection between the boss and the shaft which takes part of the driving torque. The hub 11 has a fixed splined connection with the driving shaft 7 and externally has a sliding ball-race connection 16 with the grooved hub 8. The hub has sockets 9 carrying the roots of the blades 10 and the whole complete propeller is adapted to be movable longitudinally under the restraint of springs 31 up to limit stops 33. In addition to taking the torque through the ball-races 16, an external drive is obtained by means of arms 25 attached to a boss 24 secured to the shaft, which arms have connection at 40 with rings 41 on the outer parts of the hub sockets. Complete connection is made by a coupling pivoted at 40 and at 27 through two members 36, 38 which are longitudinally free but under spring restraint 44 and also are relatively free rotationally. The same levers 25 are also connected by other pivotal members 27, 28 with rings 18 attached to the blade roots so that on relative movement of the hub to the shaft, these levers effect a change of pitch. The ring members 18 are provided with enlargements 35 the centrifugal forces on which are designed to balance the torsion of the air forces acting on the blades. In a modification the ball-races 16, include tongues which project into the boss and take part of the drive.

Abstract: 1415522 Hot pressing silicon nitride LUCAS INDUSTRIES Ltd 27 March 1973 [6 April 1972] 15883/72 Heading C7D Hot pressing of Si 3 N 4  based ceramics is effected in a graphite die with a barrier material between the ceramic and the die walls which forms a barrier layer on the ceramic to prevent reaction between the ceramic and graphite die. The barrier material is preferably Al 2 O 3  or a compound such as the hydroxide which generates Al 2 O 3  on heating. The barrier material may be applied as a spray coating on the graphite die surfaces or as a spray or immersion coating on a preformed compact of the ceramic. The Al 2 O 3  is preferably applied as a slurry in collodion and acetone. The Al 2 O 3  forms a barrier layer of silicon aluminium oxynitride on the Si 3 N 4 .

Abstract: 830,410. Carrying vehicles on vehicles. ACF INDUSTRIES Inc. May 20, 1957 [May 23, 1956], No. 15901/57. Class 78 (4). The front end of a semi-trailer carried on a rail or other vehicle is supported by a member P (Fig. 2) carried by restracting legs N, O from the carrier vehicle. Preferably one of the legs, O, is in two telescoping parts connected by springs which oppose changes in length in either direction to provide a resilient support for the semi-trailer. In the construction illustrated the lower end of the leg N is connected by a yoke 6 to a nut 12 moved by a screw 14 adapted at its end 20 for engagement with a power wrench. A cam 64 engaging the lower end of the leg N modifies the velocity ratio of the linkage and a spring 62 assists in raising the device. In an alternative construction the lower end of the leg N is pivoted directly to the nut 12 and moves towards the pivot 26 of the leg O, in retracting, instead away from that pivot as shown. The member P supporting the trailer may be pivoted about the axle 32 jointing the legs N and O, or about a separate pivot on the leg N, and is held roughly horizontal by springs 63. The member P includes a fixed jaw R (Fig. 9) and a jaw F which can be slid by a screw 48 to co-operate with the jaw R to embrace a king-pin projecting from the trailer. A yoke 54 pivoted at 52 to the moving jaw S is automatically raised to embrace the king-pin, as the jaw F is moved towards the jaw R, by a ramp 56. A locking bar 58 prevents accidental displacement of the jaw F. Alternatively the jaw R may move and the jaw F be fixed; the yoke 54, which serves to pull the king-pin away from the fixed jaw R is then omitted.

In the form shown, the plug is split diametrically at 21 and tightened in its seating by rotation of the expander bar 45 in either direction so that the ridge thereon engages the parts of the plug beside the groove in which it is shown. The pin 43 on the lever 44 may be moved by a slotted lever on the end of a small spindle passing through the centre of the main spindle 8, and the latter may engage the plug by a dog coupling, or as shown the spindle 8 may terminate in a plate 33 having a slot 42 for the pin 43 and projections 34 engaging pawls 36 pivotally mounted on the valve plug. The recesses 39 allow the pawls to fall away from the projections 34 in the fully open or closed positions of the plug, so that rotation of the spindle may be continued to actuate the expander bar. According to the Provisional Specification the locking bar 45 and the hole in which it rests may be of oval or parabolic section or may be screwed and tapered, while an embodiment is also described in which the projections 34 and the pawls 36 are interchanged.
