[A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 2, 1938.] [Class 46] For the process for purifying used lubricating oils by passage without pressure or suction through a film of the impurities deposited on the surface of a porous medium, as described in the parent Specification, elements of the leaf filter type are used, which elements are provided with reciprocating scrapers held in contact with the filter elements to remove excess of impurities therefrom as they nose downward, but withdrawn from the elements during upward movement. Filter elements 6, Figs. 1 and 2, are supported by their outlet fittings 15 on conical seatings on a cross-beam 19 in a heat-insulated tank 1 and held in position by cross-beams 25 which are hinged at one end to the wall of the tank. The oil to be purified is poured into the tank through a strainer 5 in a depressed part of the, cases. The tank has a thermo-statically controlled heater 29. Scrapers 42, Figs. 6 and 7, are arranged on either side of each filter leaf and supported at the ends by rods 37, 38 attached to endless chains 35 passing round pulleys 32 on shafts 31. The lower shafts are connected by another endless chain 50 and one of the upper shafts can be turned to drive the chains and thus give the scrapers a reciprocatory up-and-down movement. The scrapers during their downward movement are held against the faces of the filter elements by springs 41 on the rods 37, 38. At the bottom of their downward movement spacing cams 44 abut against stops 46 and are moved to force the scrapers apart and away from the faces of the filter elements. They are left apart during the upward movement until the cams abut against stops 45 and are moved to allow the scrapers to again come in contact with the faces of the elements. The scrapers bear on wires 51 arranged over the filter surfaces at an angle to the perpendicular. The wires determine the thickness of the film of deposited impurities left on the surfaces of the elements. Electrical heaters may be provided inside the filter leaves.

Abstract: 1,079,483. Automatic voltage control. SIEMENS SCHUCKERTWERKE A.G. Feb.16, 1966 [Feb. 16, 1965], No.6888/66. Headings G3R and G3X. A D.C. supply arrangement comprises a first transformer m2 connected to an A.C. supply UW and having its secondary winding connected to rectifiers n3, n4 to produce a voltage UG2, and a second transformer m1 which has a higher transformation ratio than transformer m1 and which is connected to the supply UW over a p.t.c. resistor K, the secondary winding of m2 being associated with rectifiers n1 n2 to produce a voltage UG1 and the voltages UG1 and UG2 being connected in parallel to provide the direct voltage output UG of the arrangement. In operation, with low values of UW, voltage UG2 is negligible with respect to UG1 which thus substantially constitutes the output voltage; as the value of UW increases, the resistance of K increases and UG1 falls with respect to UG2 until, at high values of UW, the output voltage UG corresponds with UG2. Thus the arrangement produces a D.C. output voltage which rises rapidly with increasing values of UW for relatively small values of UW, but which rises slowly, or remains constant, with increasing values of UW for relatively large values of UW. The A.C. supply voltage may be three-phase, and the D.C. output circuit may include a Zener diode stabilizer Fig. 2 (not shown). The voltage UW may be derived from the output of a variablespeed generator, the arrangement then being used to control, over thyristor circuitry, the excitation of the generator from an auxiliary source when the generator output voltage is low, and acting to switch off the supply from the auxiliary excitation source when the generator output voltage reaches a sufficiently high value Fig. 3 (not shown).

Abstract: 476,011. Turning. CESKOSLOVENSKA ZBROJOVKA ACKIOVA SPOLECNOST, BRNO. March 9, 1937, No. 6950. Convention date, March 9, 1936. [Class 83 (iii)] [Also in Group XXIV] In an automatic stop arrangement for a lathe saddle, a clutch S having a disengageable part 17 which is adapted, when prevented from rotation by the contact of the saddle with a fixed stop, to undergo an initial displacement relative to the other part 16 of the clutch, moves a connected member 23 to release the same from a securing device 26 and thus permit a source of energy 36 to complete the disengagement of the clutch parts. The pinion 7 for the rack feed movement of the saddle is keyed to a sleeve 19 which has a splined connection with an extension 18 of the driven half 17 of the clutch, normally in engagement with the other driving part of the clutch which is integral with a worm wheel 6. A neck on the end of the extension 18 is engaged by a sleeve 23, the exterior of which is in screwthreaded engagement with a nut 31 secured to the saddle. A torsion spring 36, loaded when the clutch is engaged, is secured at one end to the sleeve 23 and at its other end 38 to the saddle, the sleeve being maintained against rotation by a spring-pressed latch 26. On overloading of the clutch, the teeth tend to come out of engagement and the member 17 moves to the left drawing with it the sleeve 23, disengaging the latch 26, and thus permitting the torsion spring to complete the disengagement of the clutch.
