Patent FI-972018-A (FI)
Inventor: BAGNATO LUIGI J
IPC: B65H18/26
Filed: 1997-05-13
Abstract: A winder in a papermaking machine has a frame with horizontal rails which are positioned above a rotatable reel support drum, which is fixedly mounted. As a relatively large diameter wound paper web reel, or jumbo, is formed on a spool riding on the rails, the surface of the jumbo remains tangent to the top of the support drum as the spool moves from an initial position vertically over the reel drum to a position laterally displaced horizontally along the rail. Centerwind drive(s) control spool torque. As the jumbo increases in size, it is moved linearly away from the initial position, while maintaining the paper web reel rotatively supported and in a nipping engagement with the support drum. Nip pressure between the support drum and the jumbo is controlled by the force of gravity and the horizontal positioning of the jumbo along the rails. The positioning of the jumbo along the rail may be controlled by a conventional pneumatic or hydraulic cylinder, or a screw mechanism. An alternative embodiment winder utilizes primary and secondary arms to position the jumbo and its spool along the reel rails.

Title: Improvements in or relating to engine oil filtration
IPC: B01D35/12
Filed: 1942-01-24
Abstract: 556,304. Filters; lubricating systems. LE CLAIR, C. C. S., and TECALEMIT, Ltd. Jan. 24, 1942, No. 1021. [Class 46] [Also in Group XXXIV] In an oil filtration system, particularly a force-feed lubricating system for I.C. engines, oil is fed by a pump 25, Fig. 1, from an intake 24 in a sump &c. through a pipe 26 to a filter 1 and passes through the filter element 4 and an outlet 12 to a pipe 36 leading to the bearings until the designed pressure is reached and a spring-pressed piston valve 15 operating in accordance with the pressure connects a pipe 23 in the filter 1 with a pipe 27 for recirculating surplus unfiltered oil. The pressure exerted by a spring-pressed valve 32 in the pipe 27 causes some of the relieved oil to flow through an orifice 34 and a pipe 35 to a part of the sump remote from the intake 24. At starting, oil is repeatedly circulated and quickly heated by the heat produced in the pump, only a small amount passing through the pipe 35. As the temperature of the oil rises, more or all of the excess oil passes through the pipe 35 and heats the oil in the sump. An auxiliary filter 47, Fig. 2, may be associated with a main filter 38. Oil is fed by a pump 56 from an intake 57 through pipes 58, 63 and a three-way valve 59 to the filter 38 and passes through the filter element 39, outlet 43 and pipes 81, 82 to the bearings until a spring-pressed piston valve 73 operates to connect a secondary outlet 45 with a pipe 67 for recirculating surplus oil. Oil supplied to pipes 83, 93, being, when cold, at a greater pressure than that in a pipe 95 opertes a spring-pressed piston valve 88 to connect the pipe 83 with the inlet 52 of the filter 47, the filtered oil passing through a pipe 94 to the bearings and the surplus oil through a pipe 97 to the inlet of the valve 77. The pressure difference decreases as the oil is heated and the valve 88 operates to cut off the supply to the filter 47 and the non-return valves 53, 55 close. When the resistance of the main filter rises to a predetermined value, the auxiliary filter automatically comes into operation. By turning the valve 59 through 90 degrees clockwise, or anti-clockwise, the filter 47, of the filter 38, may be isolated for cleaning. The filter 38 may be used alone, the filter 47 with the pipes 94, 97 being removed and the pipe 63 connected by a pipe 58a to the pump. Two or more main and auxiliary filters may be provided in a single casing. The Provisional Specification comprises also slightly modified forms of the control valves 73, 88. In the valve for the main filter the piston rod passes through a hole in a perforation diaphragm, on which the spring bears, and in the valve for the auxiliary filter, the diaphragm is imperforate and the space above it is connected to the pipe leading to the bearings.

[Also in Division E2] A lighting fixture comprises a housing having a front face with an opening to receive a frame member having a light-transmitting panel which closes the opening in one position and is provided with axially aligned trunnions extending from opposite sides of the frame, means for engaging the trunnions consisting of rearwardly facing vertical surfaces and horizontal surfaces spaced therefrom on the side walls of the housing, the vertical surfaces engaging the trunnions in the closed position and the horizontal surfaces engaging the trunnions in the open position and complementary fastening means on the housing and the frame member to secure this in the open or the closed positions. In one form, the door 12, Fig. 3, of an illuminated sign which may be designed for flush fitting in a wall 16, has a flange 38 which rests against a projection 36 on the side wall of the fixture and may be secured in closed position by a spring catch 50 on the inside of the bottom of the housing. A pair of trunnions 44 rest against the top of a trackway 22 on the side walls. Pressure on the upper part of the door 12 causes this to swing inwards on the projections 36, releasing the catch 50. The door then drops to the position shown in broken lines with the trunnions resting in the angle 26 of the trackways 22. The lower edge of the door is then lifted and the door slid until the top edge engages under a projection 20 on the inside of the top of the housing, the trunnions sliding on the horizontal parts of the trackways, the door being thus held in open position. In a modification, the trackways are replaced by contoured recesses 58, Fig. 12, consisting of an inlet slot 60 for the trunnions, a rear portion 62 in which the trunnions rest in closed position and a front portion provided with an elongated vertical slot 66. The lower edge of the door has a rib engaging a truncated pyramid portion on the bottom wall of the housing. The door is lifted in an arcuate path from the closed position to transfer the trunnions 44 from the portion 62 to the front portion, the trunnions which are oval in shape entering the slots 66 when the door is in horizontal position, engagement between the trunnions and the slots retaining the door in this position.

Abstract: 1489461 Thermal regenerators; ventilators MILJATOR AB 15 Jan 1975 [21 Jan 1974] 1664/75 Headings F4K and F4V Regenerative apparatus for ventilating a space and at the same time reducing the loss of heat or cold from the space via the ventilating air, comprises a housing 1 with ports 5 and 6 therein for the admittance and discharge of air to and from the housing, the housing containing a reversible fan 8, air-temperature sensing detectors 10, 11 and a matrix 2 of spaced-apart heat-transfer plates 3 providing air flow passages 4 between adjacent plates; the apparatus including also means 12, 13 responsive to the detectors 10, 11 for reversing the fan at predetermined temperatures of air passing out of the passages 4 to the housing outlet. In one example of use described the port 6 communicates with the external air, the port 5 with a room to be ventilated, and the plates 3 are at room temperature. With the fan operating to draw-in external air (direction 15 and assumed to be colder than the room air) via the port 6, the plates 3 are thereby gradually cooled until the air temperature at the air exit from passages 4 (i.e. adjacent port 5) falls sufficiently to act on sensor 10 thereby reversing the fan 8. The room air now circulates (direction 16) through the passages 4 gradually warming the heat-transfer plates 3 until the temperature of the air discharging from passages 4 is sufficiently high to actuate sensor 11 and again reverse the fan 8. In use, fan reversals will take place frequently, e.g. every six to nine minutes depending upon the temperature difference between the external air and the room air.
