Patent CH-681480-A5 (CH)
Inventor: PELET CLAUDE
IPC: F23D11/38
Filed: 1990-06-07
Abstract: In the operation of a pressurised atomising nozzle, the liquid fuel atomising cone from the nozzle (4) is mixed with a gaseous medium (7) in front of a first screen (3) which is mounted downstream of the nozzle (4) in the flow-off direction. In this connection, this atomising cone is struck radially and/or quasi-radially by the gaseous medium (7). In this connection, the original atomising angle from the nozzle, which amounts to around 40 DEG , is reduced to less than half. To this end, it is sufficient if the gaseous medium (7) has a pressure of 20 mbar. The new atomising angle is established with the first screen (3), there being provided in the flow-off direction according to requirements a second screen (2) which functions according to the same principle as the first, i.e. in the case of the second screen also, the mixture already produced is struck radially and/or quasi radially by the remaining proportion of the gaseous medium which was not used at the first screen (3). By changing the distances (D) between nozzle (4) and front wall of the first screen (3) and between rear wall of the first screen (3) and front wall of the second screen (2), the atomising cone of the mixture is varied between full cone and hollow cone. In the case of two screens (3, 2), their throughflow is to be kept roughly the same.

Title: Safety shut-off device for a pressurised circuit or pipeline
Inventor: STAEMPFLI JACKIE
IPC: F16K17/28
Filed: 1978-12-07
Abstract: The device comprises a pipe (1) intended to be interposed in the circuit or the pipeline, a piston (3) which can be moved with respect to the pipe and arranged so as to shut off, in one of its extreme positions, a passage section of the fluid through the pipe, and so as to supply, in another position, an outflow passage for the fluid, means (4, 31 to 34) for adjusting the section of the outflow passage so as to establish, under normal operation, a specific fluid pressure difference between the upstream and downstream sides of the piston, and means (4, 6) for keeping the piston in equilibrium, counter to the pressure difference exerted on its upstream and downstream sides, up to a threshold value of this difference. Exceeding this threshold value for example due to the pipeline breaking in its part located downstream of the device leads to a displacement of the piston as far as the position for shutting off the pipe. The device may be used particularly in a pipeline for distributing a compressed gas, a pressurised vapour, or a liquid such as water or crude oil. <IMAGE>

Title: Dopa optical resolution by selective crystallization from superstaura
Filed: 1971-05-10
Granted: 1972-01-14
Abstract: The optical isomers of DL-(3,4-dihydroxyphenyl)alanine (dopa) are produced by preparing a supersatd. acidic to neutral solution of dopa which contains an excess of one of the two optical isomers and, after partial crystallisation has taken place, isolating the precipitated isomer by conventional methods. The isomer which is present in excess crystallises selectively from the supersatd. soln., and if the crystallisation is interrupted at an appropriate point may be isolated in pure form. One advantageous way of carrying out the procedure is to seed a supersatd. soln. of DL-dopa with crystals of the desired isomer. After separation of the crystallised isomer there is obtained a soln. in which the other isomer predominates, and this soln. can be supersatd. and the procedure repeated for this other isomer. L-Dopa is of use in the treatment of Parkinsonism, but the D-isomer is inactive.

Title: Ammonium nitrate prodn - with automatic control of neutralisation
IPC: G05D21/02
Filed: 1971-06-09
Granted: 1973-01-19
Abstract: The mfr. of ammonium nitrate by reaction of NH3 with HNO3 is automatically controlled by an appts. which measures the input of NH3 and regulates the input of HNO3 accordingly and also measures the pH of the condensate of the steam resulting from the neutralisation process. Any variations from a predetermined figure are controlled by the adjustment of the input of HNO3. This method of control minimises losses of NH4NO3, and HNO3 and gives a product of uniform quality despite variations in the input of HNO3.

Title: Drying appts - for (in)edible granular materials
IPC: F26B17/12
Filed: 1972-01-24
Granted: 1972-09-22
Abstract: Appts. is suitable for grain, peas, beans, seeds, rice and similar substances. A simple type of dryer comprises an inclined chamber with a perforated base together with a perforated roof with unperforated walls. A large closed enclosure extends beneath the inclined drying chamber and an upper chamber, for the escape of air, extends above the roof. The grain enters the drying chamber through a vertical hopper and its flow is controlled by a flow orifice and a valve, with rotary blades, at the lower end of the chamber. An ascending current of hot air is blown through the grain in the superimposed chamber: it agitates and stirs the grain during drying by the use of static equipment in the chamber. The perforations in the base are in staggered rows and are obtd. by a stamping process. this operation produces small caps which terminate in slits. The caps cause the emerging air currents to pass above the surface of the base in the flow direction of the grains. The dryer may comprise a number of inclined drying chambers of the type described.
