Abstract: Burner for a suspension of fine-grained coal in a liquid, particularly water, which burner operates according to a combination of the rotary burner and toroidal burner principles. The fuel is supplied axially behind a transverse distribution baffle (12,31, 55,65) within a conical rotary body (10, 30, 50,60). At least the outer rim portion (13,62) of the inner side of the rotary body (10, 30, 50, 60) forms an angle of35-80° with the axis of the burner. At the outer edge (13, 45, 64) of the rotary body there is an annular air supply nozzle (16, 46, 70) for supplying a conically diverging outwardly directed air stream (17,47). Outside the air supply nozzle and at a radial distance from it, there is a conical guide baffle (18,48) which at its outer end may be curved inwardly (at 22, 48') and which, together with the diverging air stream, serves to produce a positive recirculation of combustion gases, non-combusted coal particles and ash particles in a direction back towards the rotary body in accordance with the toroidal burner principle.

Patent NL-67183-C (NL)
IPC: C06B45/10
Abstract: Nitropolystyrene containing from 9.4 to 14.4 per cent of nitrogen is prepared by adding one part of granular polystyrene to at least eight parts of a nitrating acid of an analytically determinable composition of 90-60 per cent nitric acid, 10-40 per cent sulphuric acid or oleum calculated as sulphuric acid and 8 to -3 per cent water (by difference), stirring and cooling the acid during the addition until the suspension is dissolved to form a viscous liquid and then precipitating, e.g. by pouring it into water or diluted refuse acid of at least 40 per cent water content or by adding concentrated sulphuric acid.  The nitrating acid is preferably at a temperature of 0 DEG  to -15 DEG  C. and the polystyrene added quickly with stirring, the nitration continuing at a temperature of between 0 DEG and 60 DEG  C.  The nitropolystyrene may be purified by washing with cold water, steaming for one hour at 90-100 DEG  C. and grinding under water.  The products are soluble in nitric acid, nitroglycerine and dinitroglycol.  Those with a nitrogen content above 11.8 per cent are also soluble in aldehydes and ketones such as cyclohexanone, cyclopentanone and furfural. They can be plasticised by most liquid aromatic and aliphatic nitro-compounds, e.g. dinitrotoluene mixture oil, nitrobenzene and nitromethane.  The nitropolystyrenes are useful as binding agents for explosive and incendiary compositions and as hard, water-repellent coatings.

Inventor: TEGLUND LARS
IPC: E03F7/00

Abstract: A liquid-plug-creating device includes a collection tank or basin into which liquid flows such as the outflow from sanitary appliances. From the outlet at the bottom of the tank a riser extends upwardly at an acute angle to the horizontal. At the opposite end from the tank outlet, the riser terminates in a bend which reverses the direction of flow through the riser into a downwardly extending vertical pipe. A U-shaped piece of pipe with a horizontal outlet is connected to the lower end of the vertical pipe and provides a special form of trap. When the tank and the riser are completely filled with liquid, any additional liquid added exceeding a minimum flow, causes a liquid seal to be formed in the piece of pipe at the lower end of the vertical pipe. The excess flow creates a vacuum in the vertical pipe which sucks the liquid through the riser out of the tank in the manner of a siphon. The liquid immerges from the device in the form of continuous plugs with high kinetic energy content. The device permits the use of small-diameter pipes in house drainage systems while assuring the required self-cleansing effect, even if water-conserving flush toilets are connected to the device. Other fields of application of the device are irrigation and the metering of liquids in batches.

Abstract: The invention concerns a method and an arrangement for generating smoke for smoke treatment of foodstuffs. The smoke is developed by means of a technique in which combustion takes place from above, the smoke being used only when there is a charcoal layer of 0.5 to 100 mm on the fuel stack, which has arisen during combustion of the fuel. The charcoal layer acts as a regulator of the combustion air flow, the combustion being allowed to take place at a temperature which is advantageous as regards the development of odours and hazardous substances. The layer of charcoal also acts as a selective filter and removes hazardous substances from the smoke. <IMAGE>

Inventor: ELY GARY W
IPC: G05B19/04

Granted: 1999-09-21
Abstract: A veneer lathe apparatus control system and method are described for automatic adjustment of lathe components which engage the log during peeling in response to reduction of the log diameter and to changes in the surface temperature of the log. The lathe components which are automatically adjusted include the lathe knife pitch angle, the knife gap spacing from the nose bar, and the radial positions of backup idler rolls and of core drive rolls. A computer control system is employed for such automatic adjustment of the lathe components in response to control signals produced by a temperature sensor which senses the surface temperature of the log and by a lathe carriage position sensor whose output indicates the diameter of the log as it is being peeled. Adjustment curves selected by the computer, such as pitch angle profiles and knife gap curves, are stored as data tables in the data memory of the computer. These adjustment curves include families of curves for many species of wood with each family having curves of different log temperatures to provide offset temperature adjustments between adjacent curves for different temperature ranges.

Filed: 1990-04-17
Granted: 1997-01-21
Abstract: A vent valve device having a pair of diaphragm-type piston members forming a pilot chamber therebetween.  The one piston controls a vent valve via which brake pipe pressure is vented locally, while the other piston controls a pilot valve to control venting of the pilot chamber.  A breather choke between the pilot chamber on one side of the other piston and a control chamber on the opposite side establishes a predetermined pressure differential thereacross only when brake pipe pressure supplied to the pilot chamber is reduced at an emergency rate to thereby actuate the other piston to a position opening the pilot valve.  In addition, this other piston operates a cut-off valve to isolate the pilot chamber from brake pipe pressure so that the pilot valve quickly exhausts pilot chamber pressure.  The one piston controlling the vent valve is in turn actuated by the exhaust of pilot chamber pressure to positively effect an unrestricted, local reduction of brake pipe pressure via the vent valve when this one piston is actuated.
