Title: Improvements in or relating to filtering the oil in lubricating systems of internal combustion engines
IPC: B01D29/00
Filed: 1922-01-03
Abstract: 199,752. Sweetland, E. J. Jan. 3, 1922. Filters having sheet filtering - materials. - The oil in an internalcombustion engine for motor vehicles is circulated by a pump through a filter of such filtering capacity as to clarify the oil and remove all cloudiness, and of much greater effective area than the cross-section of the casing in which the filter elements are contained. Dirty oil enters the filter casing 1 by a pipe 50 and sight-glass 28<a>, and the clarified oil which collects in a central tube 18, passes through a second sight-glass 39 to a pipe 44. On the tube 18 are mounted a number of filter elements 15 consisting of coarse wire mesh 60, Fig. 7, covered on both sides with cloth or wire fabric 61. From the interior of each element the oil passes through holes 23 to the tube 18. An alkaline filter dressing containing kieselguhr or like material is introduced into the casing through an opening 8 and adheres to the elements 15. A number of rods 28 suspended from spacing-washers 27 on the central tube can swing to a limited extent in the lower part of the casing and serve to scrape the dressing from the elements 15 when the central tube is rotated by means of an external handle. The dressing can then be removed through a plugged opening 9 by means of a scraping disc 11. A cock 45 is provided to enable samples of the filtered oil to be taken. For the purpose of heating the oil, a jacket 12 is connected with the exhaust-gas or with the hot water system of the engine.

Title: Improvements in or relating to electric circuit breakers and trip devices therefor
IPC: H01H71/10
Filed: 1944-01-06
Abstract: 574,116. Automatic circuit-breakers. SHEPHERD, G. R. (Westinghouse Electric International Co.). Jan. 6, 1944, No. 280. [Class 38 (v)] A multipole circuit breaker thermally operative on prolonged overloads and electromagnetically on high momentary overloads, comprises a partitioned insulating housing 11 and cover 12 through which projects the operating lever 63. Three-switch arms 27 each have the movable contacts 21 pivotally mounted at their ends by pins 26. A doubletoggle arrangement comprising a rod 79 and spring 77, and links 49, 51 and overcentre springs 53, holds the movable contact 21 against the fixed contact 17 to and from which it can be moved by the hand lever 63, provided the cradle 55 is held in the latched position. The tripping mechanism comprises a trip shaft 87 with latch 111 engaging the end 113 of the cradle 55. The trip shaft is rotated counter-clockwise on overload either electromagnetically by an armature 139 for each pole striking the cam 141 on the trip shaft 87 and simultaneously closing the contacts 144 and 148, thus protectively shunting the bimetal strip 39. Alternatively the bimetal strip 39 unlatches at 109 the spring-controlled lever 93, which is pivoted at 97, thus allowing its end to strike the cam 115. After tripping, the latch-system is reset by first rotating the lever 63 anti-clockwise from the half-way position (to which it is moved by the tripping), during which the trip shaft is rotated clockwise by the action of the cradle 55 on the cam 155 and engagement of the latches 109, 111 ensues. The contacts are re-closed by restoring the handle to the Fig. 2 position. The bar 29 carrying the switch arms 27 and the trip bar 87 are common to all poles and pass through the dividing partitions where they have flanges to seal the apertures against flash-over between the poles. A spring 143 in a recess in a partition bears against a flat surface on the trip bar 87 to bias the bar in both directions towards its normal position.

Jan. 9, 1933, No. 732. Convention date, Nov. 30, 1932. [Class 100 (iii).] Assembling matrices.-In order to prevent twisting or displacement of the matrices in the first elevator in the case of short lines, which involve the use of centralizing or quadding devices, a pressure-bar mounted in the front wall of the elevator is adapted to act upon the last matrix only of the line. The bar is retracted before the elevator reaches its upper position, to allow the matrices to fall, or be depressed, into the lower position. The matrix-line is, as heretofore, supported at its leading end by a U-shaped yielding resistant, and pawls D<2>, Fig. 4, engage behind the last matrix. The pressure-bar J is pivoted at its leading end J<1>, and its rear end is pressed into the elevator channel by a spring J<3> acting on a lug J<2>. The bar is disposed at an angle to the matrix-line, and is slightly concave, so as to engage only the last matrix. A short line, the rear end of which is out of contact with the pawls D<2>, is thus adequately supported. The bar J is retracted, when the elevator rises, by a plunger K, Fig. 7, the stem K<1> of which engages a fixed bar on the machine frame. The bar J is wide enough to engage the upper ears of the matrices in either their upper or lower position. Specification 387,279 is referred to.
