Abstract: 1,137,369. Sieves. E. J. TAYLOR-SMITH. 31 Aug., 1966, No. 38799/66. Heading B2H. A screening apparatus comprising inclined vibratory screen(s) 35, 36, arranged Fig. 2 to receive the material at its upper end, the screen(s) having uniform apertures, ejectors 37, 38 having spaced engaging surfaces below and parallel with the screen(s) so that at least part of each of the surfaces lies directly below a corresponding aperture and spaced below the screen(s) by a distance equal to the aperture dimension. The ejector surfaces are sufficiently spaced apart to permit passage of uniformlyshaped particles passing through the screen(s) and means viz. an eccentric shaft arrangement 27 moves the ejectors in a direction normal to the plane of the screen to eject the elongate pieces of material upwards out of the apertures. If an elongate piece or "shard" becomes jammed a bar 72, fig. 4, of an ejector together with a plate 40 and rib 44 break the shard into small enough pieces to pass the screen. As described, tandem screens 35, 36 overlap and have tandem ejectors 37, 38, and below them is a screen 39. The screens 35, 36 are secured in side panels 46 which rest upon springs 54. the arrangement being vibrated by rotation of a shaft 19, Fig. 3 having an eccentric central portion 21. A further frame 60 similarly vibrated on springs 54 by a shaft 27 supports the ejectors 37, 38, which are composed of parallel spaced bars 72. The shafts 19, 27 are disposed so that the screens 35, 36 and ejectors 37, 38 and also the screen 39 vibrate in opposition.

Title: Process for rendering niobium and niobium base alloys resistant to oxidation
Inventor: POKORNY ERNST ADALBERT
IPC: C23C16/30
Filed: 1961-11-01
Abstract: Niobium and niobium base alloys are protected against oxidation at elevated temperatures by forming a coating on the surface of the Nb or Nb base alloy consisting of one or more stable compounds chosen from one or more of the groups of nitrides, e.g. of Si, W, Mo, V, Ti, Al and rare earth metals; borides, e.g. of Cu, Mo, Ti, W, V, Al and Zr; arsenides, e.g. of Fe, Co, Ni and Cu; and oxides, e.g. of rare earth metals, Pb, Bi, Sn and Sb.  For nitrides, the Nb or Nb base alloy may be first treated with a halide or carbonyl of the above elements at a temperature of 900-1200  DEG C. to deposit these elements, then nitrided using nitrogen or a compound thereof e.g. NH3. For borides, the Nb or alloy, first provided with a layer of the above metals, may be treated with a boron halide or solid B may be diffused into the layer. Nitriding and boriding are preferably effected at between 1000 and 1500  DEG C.  The above elements for arsenides and oxides may be first incorporated into the Nb surface by merging the green compact of Nb powder into the above fused element, then the coated surface treated with As or B, or O by controlled oxidation.  Alternatively, any of the above stable compounds may be pressed mechanically on to the Nb surface, then heat treated or sintered.ALSO:Niobium and niobium base alloys are protected against oxidation at elevated temperatures by forming a coating on the surface of the Nb or Nb base alloy consisting of one or more stable compounds chosen from one or more of the groups of nitrides, e.g. of Si, W, Mo, V, Ti, A1 and rare earth metals; borides, e.g. of Cu, Mo, Ti, W, V, A1 and Zr; arsenides, e.g. of Fe, Co, Ni and Cu; and oxides, e.g. of rare earth metals, Pb, Bi, Sn and Sb.

Class 34(2) On energisation of a spin-drier motor 4, Fig. 2 the drier drum 2, due to its inertia and a slidable and rotatable connection between the motor shaft 9 and a drum mounting sleeve 16, rides vertically up the shaft so disengaging friction braking surfaces 12 between the drum and the motor. Such movement is effected through ball mounting complementary spirally grooved surfaces 20 formed in the sleeve 16 and a member 13 fast with the motor shaft which. allows the initially accelerating shaft to rotate faster that the drum until the sleeve 16 rises and abuts a plate 14 fixed to the shaft. When the motor is switchedoff the spinning inertia of the drum effects a downward spiral movement of the sleeve 16 along the grooves 20 to ensure brake re-engagement. In a modified drier the grooves 20 are replaced by interengaging square threads formed in both the sleeve 16 and the member 13. In yet another drier cam rollers 22, Fig. 4, fixed to the shaft 9 engage surfaces 21 formed at the lower edge of the sleeve 16 whilst on a fourth embodiment the axial movement between the motor and the drum is effected by links 23, Fig. 6, pivotally connected to the sleeve 16 and the member 13.

In servo-mechanisms for operating loads with high inertia, e.g. gun laying gear 10, and comprising a variable-speed gear 8 through which the load is driven by a motor 9 and means for adjusting the gear ratio comprising an hydraulic piston 5 controlled by a valve which is operated by a relay 4 under the control of an amplifier 3 responsive to the error between synchros 2, 11 driven by a fire control instrument 1 and the output shaft of the variable-speed gear respectively, oscillations of the operated element are minimized by providing the variable-speed gear with means for causing a loss of energy when the gear is transmitting high torques, which means are inoperative when the gear is transmitting lesser torques. When the variable speed gear is an hydraulic pump and motor combination the said means may comprise a spring-loaded valve which opens to allow escape of fluid when the pressure is high in the gear. In the case of an electrical variable-speed gear the means may act to short-circuit a generator and motor through a resistance.
