Title: Improvements relating to oil filters
IPC: B01D29/21
Filed: 1955-12-20
Abstract: 774,968. Oil filters. FRAM CORPORATION. Dec. 20, 1955 [Aug. 5, 1955], No. 36457/55. Class 46.  In oil filter apparatus comprising a full-flow and a part-flow cartridge subjected to the same oil inlet stream the two streams of filtered oil are combined and fed directly to the engine bearings, the greater pressure drop in the part-flow cartridge being compensated for by passing the delivery flow from the full-flow cartridge through a venturi connected at its throat with the outlet from part-flow cartridge. A shell 10 is clamped to the side of a crank case 17 by a hollow central bolt 13 surrounded by apertured tubes 32 which support pleated paper elements 25, 26 constituting the full- and partflow filters. Oil from the crank case 17 enters an annular channel 20 in the wall thereof, rises to an outlet port 22 and flows into the shell 10 whence it advances radially inwards mostly through the full-flow paper element 25, the adjacent tube 32 and apertures 38 into the central tube 13. The tube leads it into a venturi 44 where, through apertures 47 in the venturi throat, it draws oil through the partflow filter 26, the two united flows being delivered through a passage 50 to the bearings to be lubricated. A byepass valve 41 in the tube 13 ahead of the venturi 44 provides an oil passage when the filter 25 becomes clogged. In a modification the two cartridges are not in alignment and the byepass valve is beyond the venturi.

Title: Method and device for the formation and transport of blanks, formed of particles such as wood shavings, fibres and the like destined to be compressed to boards
IPC: D21J1/00
Filed: 1961-10-12
Abstract: Wood shavings, fibres and the like are scattered on to a support made of flexible material, the supports are moved forward, the formed blanks are taken over by a press feeding device and the support freed of the blanks is returned in a closed circuit to the spot where the formation of the blanks takes place. The flexible supports 3 are carried by an endless conveyer 6 under a particle-scattering device 16 and are then transferred to a second conveyer 9, travelling at increased speed, by which they are carried into a preliminary pressing device 17, 18, the conveyer being stopped during the pressing operation. The support is then stripped from the blank which is fed on to a plate 22 by which it is raised into a heated press. Side and transverse confining walls, the latter attached to the conveyer 6, may be provided. Specification 874,938 is referred to.
