Patent EP-0184271-A3 (EP)
IPC: F01D17/14
Filed: 1983-10-12
Abstract: An aerodynamically tapered spike (60) is positioned for 
controlled axial movement in the conical portion (34) of a 
composite gas turbine engine diffuser (16) controlling engine 
air mass flow rate by adjusting diffuser area ratio at the 
entrance (38) to the conical portion (34). Also, a straight pipe 
transition diffuser portion (44) connects the conical portion 
(34) and a flat plate-type diffuser portion (50) and changes 
the velocity profile from an axially skewed profile (42) into a 
flat profile (48) at the entrance (52) to the plate-type portion 
(50). The spike (60) is fixed to an axially moveable rod (62) 
extending through an aperture (58) in the flat impaction wall 
(56) of the plate-type diffuser portion (50).

IPC: F16K5/20
Filed: 1985-09-09
Abstract: An inflatable sealing element comprises:  
(a) a body of elastomeric material having an internal chamber 
and being adapted when inflated to bear against a non-com­
pressible surface to effect a seal,  
(b) a feed spigot for supplying fluid to the internal chamber of 
(a) to cause the latter to inflate, and  
(c) a rigid reinforcing member substantially filling the internal 
chamber of (a) when the latter is in the deflated condition.  
     The presence of the reinforcing member ensures more ac­
curate positioning of the internal chamber and greater uniform­
ity of expansion of the body, thereby improving the seal.  
     The seal is suitable for use in ball valves.

Title: Process for treating a liquid involving cation exchange and selective removal of nitrate ions from the liquid, and ion exchange resin mixtures suitable for use therein
IPC: B01J47/04
Filed: 1986-12-05
Abstract: A process is disclosed for exchanging hardness ions and selectively removing nitrate ions from a liquid, e.g. water, comprising passing the liquid through a cation/anion exchange resin mixture, whereby (i) hardness ions are exchanged, (ii) cations and nitrate ions, present in the liquid before its passage through the resin mixture, are each independently removed or reduced to a desired level, and (iii) the anion exchange resin is loaded with nitrate ions to at least 80% of its nitrate removal capacity, and wherein the resin mixture is at least initially regenerated with chloride salt. If the process is used to soften and selectively remove nitrate ions from water, the disadvantageous precipitation of calcium carbonate and/or calcium sulfate during subsequent regeneration of the resin mixture can be avoided.

Abstract: The present invention provides latex grains hav­
ing latex particles which compose each coagulated grain 
compacted therein the state of not being mutually fused; 
said grains are obtained by the following steps of (A)-(E):  
(A) into a polymer latex manufactured by emulsion 
polymerization or suspension polymerization, a coagulant is 
added at a temperature lower than the temperature (soften­
ing temperature) at which latex particles are adhered by fu­
sion, to be dispersed and scattered in said polymer latex as 
minute volumes of said coagulant, before said coagulant has 
been dissolved and diffused into said polymer latex;  
(B) by letting said coagulant dissolve and diffuse into 
said latex from the scattered minute volumes of said coagu­
lant, the latex particles are coagulated on the outer surface of 
the minute volumes of said coagulant as the centers, to have 
coagulated grains grow from inside out, thereby forming 
spherical grains of an arbitrary range of sizes regularly filled 
with the latex particles;  
(C) said coagulated grains are separated from said 
polymer latex:  
(D) then, said coagulated grains are immersed in water 
in the state of holding their temperature lower than the 
softening temperature of the latex particles; and  
(E) they are dried at a temperature lower than the 
softening temperature of the latex particles. 
The polymer latex grains of this invention have small 
contents of foreign matters and residual monomers and 
permit their interior to be homogeneously impregnated with 
liquid substances; the dried grains may be homogeneously 
and rapidly dispersed or dissolved in liquid; and further, they 
are excellent in physical properties like shape holding 
property, bulk sp. gr., etc.

Title: Commutation circuit for a collectorless d.c. motor
IPC: H02P6/182
Filed: 1987-01-19
Abstract: A control circuit for a collectorless d.c. motor, without a commutation sensor, and comprising a stator with a multiphase system and a permanent-magnet rotor. The commutation state of the motor depends on the voltages induced in the stator windings. A comparison signal is generated which indicates whether the sign of that winding voltage which is not connected to a direct current source by means of the circuit electronic switching elements is in conformity with a predetermined sign which depends on the instantaneous commutation state. This comparison signal is inhibited during those time intervals in which transient effects which may cause spurious zero crossings occur in the windings as a result of the electronic switching elements being turned off. The switching elements are always switched one commutation step further if the comparison signal does not have the appropriate sign.

Abstract: Novel amino acid derivatives of the formula 
  
wherein R¹ is a protecting group removable under reducing or acid 
conditions, and R² and R⁵ are hydrogen or carboxylic protecting groups, 
are useful as intermediates in preparing stereospecific carbapenam/­
carbapenem derivatives. R¹ is removed under reducing conditions to form 
a pyrrolidine derivative, which is further cyclised from the R⁵=H 
compound to form a β-lactam ring. Stereospecificity at the 6-position 
is achieved by treatment with lithium di-isopropylamide (LDA) and 
quenching at different temperatures. Compound (I) can be prepared by 
treating R¹-protected R³-pyrrolidone carboxylic acid R²-ester with a 
lithium enolate of the formula R⁴CHLiCO₂R⁵. The lithium enolate can be 
formed from R⁴CH₂CO₂R⁵ by treatment with LDA.

Title: Process to increase the recrystillization temperature of aluminium and its alloys
IPC: C22C21/00
Filed: 1987-12-01
Abstract: The invention relates to a method for the deformational transformation of aluminum and its alloys comprising the steps of deforming the aluminum in the solid state and annealing the deformed aluminum at a temperature at which recrystallization occurs. The recrystallization temperature of the aluminum is raised and the grain size is minimized by adding to the aluminim 5 to 1000 ppm uranium prior to the deformation. The method is particularly applicable to the production of aluminum based sheets intended to be subjected to heating at a relatively high temperature, for example the heating which accompanies enamelling or brazing operations, where the heating operation could change the mechanical properties of the sheets.

Title: Improvements in or relating to data communication systems
IPC: H04L13/08
Filed: 1988-03-25
Abstract: Incoming data which is required to be passed to a desired storage location under the control of a processor is received by a store prior to being passed to a serial communications controller. The store is preferably a FIFO store and stores the data at an incoming data rate determined by the incoming transmission line data rate and feeds the data to the serial communications controller at a higher data rate under the control of a clock generator which is energised by control circuitry only when the data may be accepted by the serial communications controller. The processor can therefore control the serial communications controller to cease to process incoming data, which data is then stored until the processor can spare the time to recommence processing the incoming data.
