Title: Improvements in ligno-cellulosic fibre-board
IPC: B27N3/06
Filed: 1955-07-01
Abstract: <PICT:0809332/IV (a)/1> <PICT:0809332/IV (a)/2> <PICT:0809332/IV (a)/3> In making low-density fibreboards, fibrous lignocellulosic particles of various sizes coated with a liquid binder are fed, from a hopper 4, through vibrating screens 4a, 4b and 4c of increasing coarseness to form a loose airfelted mat B on a series of smooth metal, e.g. stainless steel, plates 2 coated with a liquid binder moving along a conveyer 1.  A sheet of absorbent paper may be applied to the coated plates.  The binder may be applied to the plates by a spray 3 or by placing on the plates a sheet of absorbent paper saturated with the binder.  The upper surface of the mat may be smoothed by a brush 5a.  The mat may be compressed and made thinner by a moving endless belt 6. Upper plates 9 are applied to the mat and a part 10 of the conveyer is speeded up to form separate assemblies comprising portions of the mat sandwiched between individual plates 2 and 9. These assemblies are arranged in a loader 11 from which they are passed into a press 12 where they are heated and pressed to dry and set the binder and form fibreboards having fine particles on their front or under surfaces and coarse particles on their upper surfaces or backs.  Two fibreboards may be bonded together back-to-back.  Before the mat is heated and pressed, a layer 8 of the binder may be applied to its upper surface by a spray 7 or by coating the plates 9 with the binder.  A layer of fine particles treated or untreated with binder may be deposited on the mat before it is heated and pressed.  The ligno-cellulosic particles may be particles of wood, bamboo, straw or bagasse.  The binder may be a synthetic resin or a protein, e.g. soyabean protein. Powdered nut shells and inorganic fillers and pigments may be incorporated in the binder.

Abstract: 516,594. Jet pulverizers. ALLEN SHERMAN HOFF CO. June 30, 1938, No. 19433. Convention date, April 1. [Class 59] A method of disintegrating and removing solid material, such as petroleum coke, from a vessel comprises subjecting the material to the breaking action of a high-pressure stream of water, discharging the water and broken solids from the vessel, separating the discharged solids from the discharged water and forcing the separated water back into the vessel in the high-pressure stream. As shown, material in a container 1 is broken up by water jets from a pipe 4 which may be revolved by a handle 9 or mechanically. The material falls into a hopper 11 which may feed the material to sizing and crushing rolls 12, 13, the crushed material falling through a sieve 14 to a sump 15. A centrifugal pump 16 draws material and water from the sump and discharges it to a collecting and settling tank 18, the solids being discharged through outlet 22 and the liquid passing through louvres 19 and pipe 20 to a reservoir 24. A pump 27 withdraws water from the reservoir and discharges it through pipe 28 to tube 6 which may also be supplied with water under pressure through pipe 29. The pipe 4 is connected to a pipe 5 slidable in the tube 6. The material from pipe 17 may be discharged into a pile, the water draining back to the reservoir 24.

When the accumulator ram rises, it first closes the port i, and subsequently acts through connections o, p to open a valve j controlling communication between the ends of the cylinder l, so that the valve n is closed by spring action. A recuperative arrangement comprises a cylinder y receiving steam bled from the engine g, this steam being subsequently compressed and returned to the supply main by a piston x, when liquid is supplied from the pump to a ram w, through a valve s. The valve s is connected to the main pump outlet valve rand is open when the liquid pressure is insufficient to open the latter valve. When the valve r is open, a valve u is also open so that liquid which has previously acted on the ram w returns to a liquid supply tank.

Apparatus for controlling the speed of D.C. motors comprises a plate 6, e.g. of insulating material or insulated aluminium, on one side of which is a metallic foil, e.g. of cupro-nickel, a portion of the foil being removed to provide a resistive track 15 and a further area or areas 25 being provided to directly contact an electrode of each of two rectifying elements of a bridge rectifier circuit, the further elements of the rectifier circuit being mounted on the reverse side of the plate. If an aluminium plate is used the foil is mounted on and insulated from it by an epoxy-glass film. The resistive track is contacted by a wiper 7 (Fig. 4) connected to another wiper 17 which upon rotation of spindle 16 contacts either one of foil areas 21 or 22, (Fig. 3) and a separate wiper is provided which completes the circuit through the resistance track and aluminium plate to output terminals 23, 24, so that rotation of the spindle in either direction from a neutral position gives a controlled output the polarity of which depends on the direction of rotation. If an insulating plate is used it may have a metal foil on its reverse side also. The plate and foil make connections to the rectifiers the elements of which remote from the plate are connected by eyelets 30, 31, so forming the bridge rectifier circuit for rectifying the low voltage output from a transformer included in a casing for the device. The resistive track provides a variable resistance when wiped which follows a non-uniform law.
