Title: Oil seal
IPC: F02C6/12
Filed: 1962-04-02
Abstract: 929,456. Stuffing-box substitutes. SCHWITZER CORPORATION. April 2, 1962 [April 26, 1961], No. 12540/62. Class 122 (5). An oil seal for a turbo-charger shaft 12, extending through a wall 31 of a housing 30 in which it is supported by a bearing 51, comprises a hood 67, 68 embracing the bearing so that oil escaping from the latter is collected in the hood and directed through an outlet in the hood away from the wall 31. The wall 31 forms also part of the compressor housing which is intermittently subjected to a vacuum. The bearing 51 acts as a thrust bearing. A flange 80 rotating with the shaft adjacent the compressor housing serves to fling radially outwards any oil passing to the exterior of the hood; a passage 65 connected through a breather element to atmosphere serves to relieve, within the space 62 around the thrust bearing, any pressure drop caused by vacuum in the compressor housing, thereby preventing oil droplets from being carried into the housing. The oil is fed under pressure through passages 52, 25 in a housing 17 to shaft bearings 26, 27 and through passages 53, 71, 72 to the thrust bearing 51. Oil escaping from the bearing 26 and directed downwardly together with that from the thrust bearing by the hood 67, 68 fall on a deflector 75 and is directed towards an opening 55 in the space 62. The breather element connected to the passage 65 is screwed into the exterior of the housing 17. The flange 80 is formed on a bearing sleeve 60 secured on the shaft 12 and sealingly engaging an aperture 61 in the compressor housing by means of piston ring seals 77.

Patent GB-878210-A (GB)
Title: A coin-box telephone instrument for telephone systems
Inventor: SEIZOV DIMITAR GEORGIEV
IPC: H04M17/02
Filed: 1960-04-12
Abstract: 878,210. Automatic exchange systems. INSTITUT ZA RATSIONALISATSIA. April 12, 1960, No. 13045/60. Class 40 (4). In a coin-box sub-station the induction coil of the telephone set is provided with an extra coil and an armature, and when line current passes through all the windings of the induction coil it attracts its armature, thus releasing a coin for cashing-in, and disconnecting the extra winding; the line current still flowing in the normal windings maintaining the armature attracted throughout the call. The sub-station apparatus (Fig. 1) is shown in the off-hook condition after insertion of a coin in the shoot. In the normal condition with the hand-set on the hook 6, the pad 13 operates the spring set 14 to disconnect the set from the line and connect the 1ÁF condenser (Fig. 2) thereacross, while the lower end 9 of the forked arm 8 opens the contacts of set 16, and the upper tongue 10 moves the flap 2 anti-clockwise about the pin 3. A coin inserted in the shoot then slides down until held between the top of the armature 18 and the lower spring of set 16. The hand-set is then taken down, whereupon the arm 8 rotates clockwise under the action of the spring 12, thus allowing the contacts of set 14 to change over and those of set 16 to close, a helical spring (not shown) pressing the latter against the coin 15. The loop to the exchange is completed from terminal B (Fig. 2) over contact set 14, 300-ohm choke, rectifier 21, contact set 16 and the dial contacts NS1 to terminal A, and the call is set up in the normal way. On the reply of the called party the usual reversal of polarity takes place and line current flows from terminal A over the dial contacts NS1, contact set 16, rectifier 22, the extra 400-ohm winding on the induction coil, the contacts 23, 24 of the induction coil spring set, the normal 35-ohm, 95-ohm and 245-ohm windings, and the contact set 14 to terminal B. The induction coil attracts its armature, thus releasing the coin 15 for cashing- in, opening the contacts of set 16, and changing- over its own make-before-break spring set 23, 24, 25. The extra winding is thus disconnected, the loop being completed via contacts 25, 24, the normal windings of the induction coil, and contact set 14, and the flux thus produced is sufficient to hold the armature 18 against the coil core.

Abstract: 895,730. Sintering machines. KOPPERS CO. Inc. April 17, 1959 [June 18, 1958], No. 13167/59. Class 82(1). Apparatus for continuous sintering and cooling of the sinter (Figs. 2 and 3) has a strand 12 below a strand 10, pallets-11 movable in abutting relation across the top of the strand 10 and the strand 12 in the opposite direction to that in the strand 10, a feeder 24 for layering the material for sintering on the pallets to be ignited by a furnace 25, exhausting means for hot gases, means for transferring the pallets 11 from the strand 10 to the entrance of the strand 12, with inward tilting of the pallets 11 in so doing for discharge of sinter, and for restoring the pallets to the upright position, a crusher 18 for receiving the sinter and discharging it to the restored pallets 11 on entry, to be cooled by introduced air, and means for transferring the pallets 11 from the strand 12 to the strand 10 in advance of the feeder 24, the pallets being tilted in so doing to discharge the crushed sinter therefrom, and for restoring them to the upright position. Each strand comprises pairs of tracks 30, 31 along which the pallets 11 are moved by means of sets of wheels 27, 28, the wheels 27 being eccentric to the centre of gravity of the pallets 11. Sprockets 13 have grooves 37 each engaging rotatably a collar 39 on the shafts 38 (Figs. 4 and 5) of the wheels 27 to tilt the pallets in discharging the sinter and to control the movement of the tilted pallets between the strands 10 and 12, a guideway 36 from the sprockets 13 to the tracks 30, 31 on the strand 12, on which they slide, acting to restore them to the upright position. In so doing a hold-back pinion 61, on the drive shaft 53 for each sprocket 13, rotatably engages the pallets 11 to prevent them jarring. The strand 10 has a hump 68 over which each pallet 11 rides for shearing the sinter cake in a pallet from that in the next pallet. Each groove 37 also rotatably engages a collar 39 on each shaft 38 to tilt the cooled sinter-containing pallets 11 outwardly of strands 10, 12 as they leave the strand 12, to discharge the sinter and to control their upward movement, another guideway 36 restoring them to the upright position. Driving pinions 43 push each pallet 11 from the sprockets 13 on to each strand against the preceding pallets, after sliding pushers 44 have pushed each pallet 11 so that the driving pinions 43 engage with racks 41 on the pallets 11, the sprockets 13, pinions 43, and pushers 44 being rotatably driven in synchronism. The sinter passes from the crusher 18 through a screen 19 driven by an eccentric-rod 66 powered by a motor 67 before discharge into the lower pallets 11. Exhausters draw the hot gases from the strand 10 through wind boxes 14, cooling air being introduced to the crushed sinter in the strand 12 through wind boxes 17. Other means may be used to transfer, tilt and push the pallets and to screen and crush the hot sinter.

Filed: 1929-04-29
Abstract: 330,088. Bunting, R. S., and British Radio Corporation, Ltd. April 29, 1929. Thermionic amplifiers; receiving-sets, control of.-The volume from a receiver or radio-gramophone is controlled bv a variable resistance or potentiometer combined with a condenser as one unit with a single knob, the resistance and condenser being independently adjustable. The resistance d, is wound over part of the circular former a and is varied by the slider n fixed to the operating shaft g. The condenser comprises two vanes, the fixed vane e, being secured to the face of an insulating disc b while the moving vane f is mounted on the shaft g. While the slider n is moving over the resistance, the moving vane f is retained in the position shown in Fig. 3, by a spring controlled detent i which is held down by a pressure plate m fixed to the slider n. When the arm n reaches the end of the resistance d, the pressure plate releases the detent i and the moving vane rotates with the shaft into the capacity field of the fixed vane e, until the notch k meets the fixed stop o. One application of the device is shown in Fig. 4 in which the resistance R acts as a volume control across the aerial inductance and is combined with the reaction condenser C; the volume thus varies as the resistance in circuit is adjusted the reaction commencing at the point where the resistance control becomes ineffective. In a modification (Fig. 5, not shown) the resistance R forms a potentiometer across the filament battery for supplying variable grid bias to the first valve V<1>.
