Title: Improved system for the full-flow filtration of a fluid flowing inside a closed circuit
IPC: B01D35/147
Filed: 1957-06-14
Abstract: 860,871. Filters. PRECISION MECANIQUE. June 14, 1957 [June 16, 1956 ; May 29, 1957], No. 18896/57. Class 46. [Also in Group XXVIII] Apparatus for filtering under full flow conditions a fluid flowing in a closed circuit comprises an annular filtering element 5 with comparatively large pore such as a woven nylon " horse hair " canvas of 200 mesh, and an annular clarifying element 6 such as a filter paper with very fine pores, mounted in coaxial superposition in a fluidtight casing 1 provided with an inlet 2 and outlet 3 for the fluid, two parallel streams of fluid flowing between the inlet and outlet, through the corresponding element inwards to central bores or recesses therein and that through the filtering element 5 flowing along a passageway 12 having a reduced cross-section adapted to produce across the element a predetermined loss of head. As shown in Fig. 1, the passageway 12 is bounded by a central tube 11 leading from the clarifying element ; the tube may be of frusto-conical form to reduce further the pressure at the outlet side of the clarifying element. As applied to the lubricating oil system of a motor car engine a casting 13, Fig. 4, secured to the crank case carries a casing 15 and provides an outlet 20 from the filtering and clarifying elements 22,23,leading to an outlet passage 18 housing a by-pass valve 31. A close-coiled spring 28 restricts the passage 30 from the filtering element 22, normal flow opening out the coils to permit increased flow and a reduced loss of pressure head across the element. The flow from the clarifying element 23 passes through a port 29 in the mounting of the coil spring 28. A flange 23a on the upper end of the clarifying element 23 substantially divides the casing 15 into upper and lower parts, the flow in the upper one being turbulent to dislodge the particles of carbon black, tars, resins &c. from the filtering element 22, these particles dropping into a carbon zone below the flange 23a and opposite the clarifying element 23 and being finally removable through a drain plug 26. The elements may be mounted on a perforated tube between end plates to form a replacement unit and be adhesively secured to an intermediate dividing plate which provides a flange functioning like the flange 23a. Specification 766,288 is referred to.

Title: Automatic electric can opener
IPC: B67B7/70
Filed: 1960-06-07
Abstract: 885,966. Can openers. BURGESS VIBROORAFTERS Inc. June 7, 1960 [Sept. 21, 1959], No. 19909/60. Class 66. An electric can opener comprises a supporting plate 1 to which is fixed a motor 8 for driving a knurled wheel 27 through intermediate mechanism, a cutter blade 41 capable of limited upward movement in order to close an electrical circuit by means of a contact switch 35, 36 and a bracket 12 which carries the wheel 27 and is able to pivot in the plate 1 by means of a shaft 13, between a can-cutting position, Fig. 4 and an inoperative position, Fig. 6, when the can may be removed. Drive to the wheel 27 includes a wheel 11, belt 20, pulley 15, sprocket 16, chain 19, and wheel 18 driving a shaft 21 to which the wheel 27 is fixed. The bracket 12 has welded to it an extension bracket 24 both brackets being apertured to receive a bushing for the shaft 21 which also passes through a curved slot 50 in a guideway 28 secured to the plate 1. The guideway 28 and a bracket 29 welded to it are notched at 43 to hold loosely one end of a plate 42 integral with the cutter blade 41. A leaf spring 45 Fig. 12 (not shown), is bent back to form a socket round the other end of the plate 42, and has an inclined portion 49, Fig. 6, which may be forced upwards by a member 57 on the bracket 12 so causing the spring to fulcrum against the underside of the plate 42 at the end where it is held in the notches 43 ; this causes the opposite end of the spring to urge the cutter blade 41 downwards. A similar force is applied to the blade 41 by a spring arm 37 carrying the contact 36 of the switch. A further spring 51, Fig. 6, apertured to receive the bushing 22 and shaft 21, slides in the guideway 28 and provides a frictional brake on the pivoting action of the bracket 12. The bracket 24 includes a portion 54 which extends into an operating button 56. When the rim of a can has been placed on the wheel 27, i.e. behind the cutter blade 41, the button 56 is pushed to the right, thus pivoting the bracket 12 and causing the can top to force the blade 41 upwards and so close the switch contacts 35, 36. Alternatively, the switch may be closed by levering the can rim down on the wheel 27 and up against the blade 41. Either way, initial rotation of the wheel 27 causes the bracket 12 to move to the final can-cutting position with the shaft 21 at the right-hand end of the slot 50 (as seen in Fig. 11). The switch is held closed during piercing and cutting of the can lid by the continuous upward pressure on the cutting edge of the blade 41. On severing of the lid this force ceases and the switch again opens as springs 37 and 45 urge the blade 41 down. The severed lid is held by a magnet 64.
