Title: Improvements in bearings
IPC: A47G23/10
Filed: 1934-03-02
Abstract: 434,809. Supporting and mounting bearings. AKTIEBOLAGET NOMY, Ulvsunda, Sweden. March 2, 1934, No. 6744. Convention date, March 3, 1933. [Class 12 (i)] In a radial thrust bearing in which relative axial movement between the bearing rings 2, 9 is prevented by the provision of at least one spherical bearing surface 16, the outer surface of the ring 9, which rolls on a cylindrical supporting surface 11, has a radius of curvature r<1> in an axial plane greater than such radius r<2> in a plane perpendicular to the bearing axis. The barrel shape of the ring 9 counteracts its tendency to assume an oblique position. The invention is shown applied to a bearing with tiltable blocks 6, but is also applicable to ball and roller bearings. A modified form is shown in which the tendency towards an oblique setting is also opposed by axially arranged springs in the ring 9 coacting with radial studs engaging the surface 11. The blocks 6 may be on the ring 9. Specification 387,196 is referred to.

Filed: 1969-02-07
Abstract: 1300056 Pelletizing powdered materials CITIES SERVICE CO 10 April 1970 [7 Feb 1969] 6792/69 Heading B5A [Also in Division B2] In a process for wet pelletizing of powdered materials in which a mass of powdered material is transected by a plurality of rotating agitating members 3 as it advances longitudinally in an elongated mixing zone 2, a liquid pelletizing medium is discharged longitudinally into the zone in the form of a diverging cone of liquid. This is achieved (Fig. 2) by a sprayer extending transversely into the zone in a conduit (Fig. 1) having an orifice 17 directed longitudinally with respect to the conduit. The sprayer contains a rotating helical vane 13 which imparts a radially outwardly directed component of motion to the liquid. The vane 13 can apparently be arranged coaxially with orifice 17 to achieve the same result. A plug 15 is provided for removing the vane and locking ring 17 for adjustment of the sprayer in the conduit. Liquid enters through inlet 16. The process may be used for pelletizing carbon black, metal oxides, clays or fertilizers. The same effect may be achieved by replacing the vane with a fan or grooves in the wall of the sprayer.

Title: Improvements in air-blast electric circuit breakers
IPC: H01H33/16
Filed: 1944-04-17
Abstract: 575,854. Air-break switches. GORDON, H. H. (Allmanna Svenska Elektriska Aktiebolaget). April 17, 1944, No. 7034. [Class 38 (v)] The arc-extinguishing chamber of a transverse air blast circuit breaker is divided into two parts 10, 11 by an insulating wall 5, made, for example, of polymerized derivatives of acrylic acid, or resins of aniline, to which are fixed insulated auxiliary electrodes 16, 21. Main electrodes 14, 19 are connected to contacts 12, 17 respectively and are electrically joined at the ends to the electrodes 16, 21 by webs 15, 20. The lower edge 22 of the insulating wall 5 has a notch 23 to hold the arc at the middle thereof. In operation, the arc drawn out between contacts 12, 17 is blown upwards by the air blast from pipe 9. The footpoints of the arc run up electrodes 14 and the arc is pressed against edge 22 and contacts tungsten tips of electrodes 16, 21, whereby the arc burns round the edge 22 from electrodes 16 to 21 and is extinguished by the air-blast. The main and auxiliary electrodes may alternatively be connected through a resistance which, inserted in the arc circuit, limits the current through it. An arrangement suitable for higher voltages uses a plurality of insulating walls, Fig. 3 (not shown). In Fig. 4, the auxiliary electrodes 16, 21 are connected through a resistance 38 which is thereby in parallel with the arc. The resistance of the arc increases due to the blast pressure and the current rapidly becomes too small to maintain the arc which is therefore extinguished. Instead of the main and auxiliary electrodes being connected, two extra walls 41, 42, are inserted to extinguish the remaining arcs. Fig. 5 shows an arrangement wherein two extra walls 45, 52 with auxiliary electrodes 46, 49 are fitted. Connections are made between electrodes 14 and 46, etc., as shown, electrodes 16, 21 being connected by resistance 38. Arcs form round the tips 50, 51, 22 of the walls.

Abstract: 636,585. Grab-buckets. ETABLISSEMENTS CAILLARD & CIE, and CAILLARD, J. G. March 12, 1948, Nos. 7637 and 7638. Convention dates, March 24, 1947 and Aug. 27, 1947. [Class 78 (iv)] In a grab comprising two jaws which are closed by moving two members comprising respectively a cross member on which the jaws are pivoted and the head of the grab secured to a supporting cable together, a lever is pivoted on either of the two members and has one arm connected by a tie rod to the other of the two members and a second arm 'secured to a cable for closing the jaws. The lever is disposed so that the one arm forms a small angle or a large angle with the tie rod according as the jaws are closed or open while the second arm makes a small or a large angle with the closing cable according as the jaws are open or closed, so that the closing force increases as the jaws close. As shown in Fig. 4, the jaws 1, 1<SP>1</SP> of a grab are pivoted at 21, 21<SP>1</SP> to a cross-member 20 and connected to move together by teeth 22, 22<SP>1</SP>. The jaw 1 is connected by a link 24 to a lever 25 pivoted at 231 to the jaw 1<SP>1</SP> and suspended by a cable 27. A lever 6 is pivoted at 2 to the cross member 20 and is connected at 7 to a tie rod 8 pivoted to the lever 25 and is connected at 9 to a hoisting cable 10 passing over a pulley 28 and serving to close the jaws. In the position shown the lever 6 causes a slight reduction of the mechanical advantage of the cable 10 compared with a direct connection to the cross-member 20, but in the closed position of the jaws, the lever causes considerable increase in the mechanical advantage. In an alternative construction, the pivots 21, 211 are co-incident, the teeth 22, 22<SP>1</SP> are omitted, and the lever 25 is replaced by a head to which both jaws 1, 11 are connected by links such as 24. In the construction of Fig. 6, the lever 6 is pivoted on the head and has an arm connected by a tie rod 8 to a cross-shaft 2 on which the jaws 1, 1<SP>1</SP> are pivoted, and an arm connected to the closing cable 10 which passes around a pulley 32 loose on the shaft 2 and a pulley 31, the arm being disposed as in Fig. 4 to increase the mechanical advantage in the closed position of the jaws while decreasing it slightly in the open position.
