Title: A method and means for indicating the sludge level in the sludge space of the rotor in sludge centrifuges
IPC: B04B1/14
Filed: 1966-08-17
Abstract: 1,099,256. Centrifugal separators. ALFALAVAL AKTIEBOLAG. Aug. 17, 1966 [Aug. 23, 1965], No. 36798/66. Heading B2P. In a sludge centrifuge, the sludge level in the sludge space of the rotor 1 is determined by means of two indicating pipes 10, 11 which extend inwardly from the sludge space towards the centre of the rotor, each pipe being connected to a separate duct 12, 13 leading to the exterior of the centrifuge and the outer end of the pipe 10 being positioned at a greater radial distance from the axis of the rotor than the outer end of the pipe 11, and means being provided for enabling liquid flows in the two ducts to be compared by sensing pressure or flow changes or by observing turbidity changes. The pipes 10, 11 may be connected to the ducts 12, 13 by means of a paring device, Fig. 2 (not shown), by an overflow with a collection chamber, or, as shown, through a seal arrangement 14 of the rubbing collar type. A pressure or flow sensing means, not shown, is inserted in each of the ducts 12, 13. Before an unacceptable quantity of sludge has been deposited in the rotor, liquid flows out through each of the pipes 10, 11 to the respective ducts 12, 13 and the sensing means show a constant pressure or flow difference irrespective of pressure changes occurring in the rotor. When the sludge level has grown inwards to the outer opening of the pipe 10, the pressure and flow in this pipe decreases as the opening is clogged while conditions in pipe 11 remain unchanged. This change of pressure or flow difference can be read off visually and discharge of sludge effected manually, or the change of difference can be sensed by means which automatically effects sludge discharge. Instead of discharging liquid through the pipes 10, 11 liquid may be supplied thereto by inserting a pump in each duct 12, 13 with a pressure or flow sensing means between the pump and the top of the centrifuge. Instead of sensing pressure and flow changes, turbidity in the respective ducts may be compared visually or by means of a photocell. Sludge is discharged through openings 4 in the rotor by actuation of a slide valve 3 and clarified liquid through an outlet duct 9, as shown, or by an overflow (9a), Fig. 2 (not shown).

Abstract: 999,317. Air conditioning. H. TEVES, E. A. TEVES, and M. TAUSEND. Oct. 5, 1962 No. 37771/62. Heading F4V. In an air-conditioning system in which conditioned high-pressure primary air is delivered to induction type room units, each having a filter and a heat exchanger through which a secondary, recirculated, air flow is induced, each unit is provided with a fan which acts to assist the primary air stream in causing the secondary air to pass through the unit. As shown, primary air from a supply duct 3 enters a sound-proofed chamber 2 in a room unit 1, and then passes through nozzles 5 into a mixing chamber 6, inducing a secondary air flow from the room being conditioned to pass through a filter 9 into a chamber 8, and thence through a finned tube heat exchanger 7, which may be for heating or cooling, to the mixing chamber 6. The mixed air flow enters the room through a grid 12. The fan 10, in chamber 8, serves either to increase the secondary air flow or, if the primary air supply fails, to maintain an air flow through the unit sufficient to condition the room. The fan may have a thermostatic control.

Title: Machine for slicing an elongated roll of material into axially shorter rolls
IPC: B26D3/16
Filed: 1963-09-26
Abstract: 976,696. Cutting apparatus; sawing. C. BOGERT. Sept. 26, 1963 [Oct. 25, 1962], No. 37914/63. Headings B4B and B5L. An elongated roll 23 of sheet material is supported in a machine and cut into axially shorter rolls by a pair of axially-spaced rotatable cutting blades 31, 32, between which is partially disposed a travelling sweeper 38 to remove cut material from between the blades and prevent binding as the blades move through the elongated roll. As described, the roll of material 23, which is rotatably supported on a bearing rotatable on a mandrel 21, is gripped and rotated by a chuck 19 driven by a motor 17 and an infinitely-variable speed pulley 18. The cutters 31, 32 are located on a movable carriage 24, and may be rotated on a common axle 33 by a motor 34, or by frictional engagement with the roll 23, or held stationary e.g. when cutting soft polyethylene. The cutters, the supporting axle 33 and the motor 34 are carried by a cross slide 36 which is movable perpendicular to the axis of the roll 23 by a piston and cylinder arrangement 37, which may be controlled by limit switches to interrupt forward travel of the blades when they approach the mandrel. The sweeper, in the form of a chain saw 38, fitting into the gap between the blades 31, 32, is looped around a sprocket 39 and around a bearing 47 having a P.T.F.E. layer 48, the teeth of the saw 38 extending outwards almost to the edges of the blades 31, 32, and is driven either by a motor 41, or via a belt by the blade motor 34. Its speed may differ from that of the blades and it may run in the same or opposite direction. A chip removal vacuum-hose on the carriage 24 has its end directly beneath the area of contact between the knife and the roll 23. The carriage includes a microswitch 43 connected to a carriage drive motor 26, to prevent moving the carriage longitudinally while a cut is being made. The relative speeds of the roll and the blades may be varied by a speed compensating mechanism to keep cutting friction down during an actual cutting operation, and in a modification the axis of the blade-axle 33 is at the same height as that of the mandrel 21 to prevent twisting of the blades.

The arms 1 are preferably mounted on a bearing assembly 5 of the type described in Specification 1504126 (see Division B1-2), the upper plate 13 being mounted on the stationary member 14 and the lower plate 11 on the rotatable member 4. The lower plate is provided with openings 12 aligned with the nozzle axes 9. When fluid under pressure is supplied to the inlet 8, fluid exiting from the nozzles causes the arms 1 and the lower plate 11 to rotate, and in Fig. 1 radially extending blades 10 mounted on the lower plate 11 cause a flow of air through an inlet 15 in the centre of the upper plate and radially outwardly across the chamber to a peripheral annular outlet 18 defined by the peripheries of the plates; the apparatus is thus supported above the surface 20 by the cushion of air which develops under the lower plate 11. In Fig. 4 (not shown), the blades cause air to be drawn into the chamber through inlets (30) adjacent to the centre of the lower plate and ejected through outlet apertures (31) adjacent to the periphery of the upper plate, the central inlet 15 being omitted; this arrangement creates a reduced pressure adjacent the surface 20, tending to apply the apparatus to the surface. The plates 11 and 13 may be made of powder moulded high density polythene and the margin of the upper plate may be provided with a seal 19, with a brush, or with rollers to assist movement of the apparatus along the surface 20. The apparatus can be used under water, for example for cleaning ships' hulls; in this case the blades 10 can be omitted, flow of water through the camber being caused by the action of the rotating arms 1, and if the embodiment of (Fig. 4) is used, the outlet apertures (31) are preferably in the axially extending wall portion 17 of the upper plate. The apparatus can also be used for cleaning runways or paper machine felts.
