Abstract: 768,825 Centrifugal strainer separators. ESCHER WYSS AKT.-GES. April 29, 1955 [May 15, 1954], No. 12499/55. Class 46. In a push type centrifugal strainer separator in which the thrust plate 6 rotates with the basket 1, to lessen the shock of discharge the plate directs the solid material on to a coaxial ring 11 rotating at a slower speed than and disposed at the discharge end of the basket in a stationary casing or catcher 3. An independent motor 13 drives the ring which widens in the direction of delivery, through a belt 12. The thrust plate 6 carries a feed hopper 5. In a modification, several rings, each rotating independently of and slower than its antecedent ring are provided and hot air may be blown through the gaps between them.

Abstract: 579,155. Electron oscillators. STANDARD TELEPHONES & CABLES, Ltd., FREMLIN, J. H., and HALL, R. N. Aug. 2, 1940, No. 12518. [Class 39 (i)] In a velocity modulated electron oscillator such as described in Specifications 541,664 and 573,490, [Group XX], polepieces 8, 9 for the focusing magnet are arranged within the envelope ; one, 9, may act as the collector electrode, its sides being covered with a conductive layer and its face shaped or coated to suppress secondary emission. The polepiece 8 is insulated from the metal envelope 6 by a lining 10 ; this polepiece may be connected to the cathode. A permanent or electromagnet may be used. An elongated cathode 4 with focusing electrode 5 directs a long beam through the fins 2, 3 within the resonator.

Title: Improvements in or relating to telescopic pit props
IPC: E21D15/28
Filed: 1946-04-25
Abstract: 611,261. Pit props. HELLEGERS. A. C. April 25, 1946, No. 12532. [Class 20(ii)] Relates to telescopic pit props and consists in clamping the upper member 1 between the wedge 4 and a pressure plate 6. Fig. 1, or between the wedge 4 and another wedge 15, Fig. 4, with friction insets 8 on their working surfaces, held in a clamping band 3 rigidly connected to the top of the lower member 2 and arranged so that the wedge 4. whose angle is smaller than the angle of friction, is drawn with the member 1 as it slides under the roof pressure into the member 2 to an extent limited by the contact of the nose N With the clamping band 3. The back surface of the wedge 4 and its bearing surface in the clamping band 3 are smooth, and it rests on a spring 9 supported bv the lower member 2. A member T having a cam C and a lever 7 is carried by trunnions t in slots B in the parallel arms of the clamping band 3. In Fig. 1 a transverse horizontal wedge 5 is interoosed between the pressure plate 6 and the member T. In Fig. 4 a pressure plate 16 is interposed between the wedge 15 and the member T. and the wedge 15 may have another friction inset 18. The wedge 5, or the, wedge 15, is first placed loosely in the clamp, the wedge 4 then being held up by the spring 9 and the member T being in the position for the cam C to exert horizontal pressure, i.e. with the leyer 7 downwards. By the alternate use of wedges 19 inserted through slots S in the lower member 2 and engaged either beneath the member 1 or under the upper margin of a slot s therein, and hammered in, the upper member is adjusted hard against the roof. The wedge 5, or the wedge 15, is then driven in tightly and the wedges 19 withdrawn. When the roof pressure increases the member 1 slides into the member 2 and takes with it the wedge 4, so increasing the clamping pressure which, if the working surfaces of the member 1 are parallel, reaches its maximum when the nose N meets the clamping band 3. The wedge 15 is not drawn down with the wedge 4, since its angle is greater than the angle of friction. The working surface of the member 1 may be at a slight angle, small enough for the clamping pressure, though increasing on further sinking of the member 1. to remain below the limit of destruction of the prop by splitting. To release the prop the member T is rotated through 90 degrees. by a cable connected to the lever 7 or by hammering lateral projections 17 thereon. In the arrangement of Fig. 1 the prop may also be released bv hammering the thin end of the wedge 5, and in this case a bar mav replace the member T. The pressure plate 6 may be symmetrical, so that the wedge 5 can be inserted from either side. The friction insets may consist of base members of soft iron in which aluminium or aluminium alloy is inset.

In a bladed rotor or stator of an hydraulic, steam or gas turbine or an axial-flow compressor, the spacers of a set of spacers between adjacent blades of a circumferential row of blades are of different circumferential dimensions one from another. In the axial-flow compressor shown, the stator blades 11 of a circumferential row are mounted in grooves in the two halves of the stator casing 25 and the blade roots are spaced apart by means of spacers 28, 29 ... 37, the circumferential widths of the spacers increasing in arithmetic progression from 28 to 37. The spacers in the two stator halves may be similarly bladed whereby the lower half is a mirror image of the upper half. Alternatively, the spacers of the two halves may be arranged as shown so that spacers at diametrically-opposed points are of equal circumferential dimension. Again the spacers may be disposed at random around the circumferential assembly of blades. The object of the invention is to reduce or avoid the harmful effects of resonance.
