Title: Gas filtering installation
IPC: B01D46/24
Filed: 1967-08-05
Abstract: A filter for removing radioactive solids from incinerator effluent gas comprises a set of filtering tubes 4 through which the gas is fed from inlet 1 to outlet 2, the tubes being lined with a loose layer of asbestos fibres which are periodically removed, with accumulated solids, by probes 12 which are movable vertically into tubes 4 and connected to a suction line (Fig. 1, not shown) which includes cyclone separator (18), filter (22) and fan (26). In Fig. 2, probes 12 are lowered by winch 38 and connected to separator (18) by a flexible pipe (16). During lining, the fibres enter the tubes by inlet 62 in an air stream, the air being extracted by fan (26) through line (63). The lower parts of the filter casing, connected to inlet and outlet and enclosing tubes 4, may be removable from the upper part, enclosing probes 12 when not in use, for convenient changing of tubes (Fig. 3, not shown). In Figs. 4, 5 (not shown) the probes (102) and a spraying chamber (104), used to apply the fibres to the tube interiors, are mounted on respective trolleys which move on tracks bridging the top of the filter casing. Probes 102 are arranged in a row and during cleaning are lowered into each row of filter tubes in turn, by pneumatic motor (124). The spraying chamber (104) is lowered against spring loading by winch (118). The filter casing is normally closed by removable covers. In an alternative probe assembly (Figs. 8, 9, not shown) the probes are moved vertically by handwheel (119) and extend through felt washers, in the bottom plate of the trolley, which wipe the probes clean as they are withdrawn. The fan (134) in Fig. 4 is used for the main filtering flow as well as for the cyclone

Patent ES-360498-A1 (ES)
Title: Process of preparing lysine monohydrochloride
IPC: C07C/
Filed: 1968-11-21
Abstract: Lysine mono-hydrochloride is prepared by hydrolysing [alpha]-amino-#-caprolactam with more than 2 moles HCl/mole of lactam, recovering the lysine monohydrochloride by removing the surplus of HCl from the resulting hydrolysis mixture, at least partly by use of an anionexchanger, and thereafter recovering the HCl bound to the exchanger by forming a salt with [alpha]-amino-#-caprolactam, which salt is then hydrolysed to yield a further proportion of the lysine monohydrochloride. The hydrolysis is normally carried out at reflux temperature, and the HCl concentration is then reduced by vacuum distillation (while adding water) until the solution contains from 0À05-0À3 mole of lysine monohydrochloride/mole lysine dihydrochloride before subjecting it (in toto or in part) to anion-exchange treatment to remove more HCl and yield an aqueous solution lysine monohydrochloride from which the salt may be isolated, e.g. by spray drying. The anionexchanger bearing HCl can be regenerated either with aqueous [alpha]-amino-#-caprolactam, or with aqueous ammonia, in which case the eluate is then treated with aqueous [alpha]-amino-#-caprolactam to provide material for recycling.

Title: Braking systems for vehicles
IPC: B60T8/34
Filed: 1969-05-21
Abstract: A vehicle braking system includes a master cylinder 11 and an hydraulic line 12 connecting the master cylinder to the brake mechanisms, a vacuum operated servo-mechanism 21 which can supply hydraulic fluid under pressure to the rear brake mechanisms and which includes a valve (31) connecting an inlet (23) to an outlet 24 and which closes when the pressure from the master cylinder exceeds 100 p.s.i. to close the hydraulic line, the said pressure also causing a valve 54 to open and render the vacuum servooperative, a valve 69 being opened by a spring 74, when the pressure in the vacuum supply line exceeds a predetermined value as for example when the vacuum source fails, to open a subchamber 25a to atmosphere causing a diaphragm 26 to move under a spring 29 and force the valve 31 against the pressure created by master cylinder 11, thus holding the valve 31 open so that the master cylinder is connected directly to the rear wheel brakes irrespective of the pressure generated by master cylinder 11. The servomechanism includes a diaphragm 37, both sides of which are subject to vacuum in the inoperative position of the mechanism and the control means for the servo-mechanism includes a Bourdon tube 44 which receives fluid under pressure from the master cylinder 11 and operates an air bleed valve 49 to supply air to one side of the diaphragm, the Bourdon tube being straightened as the pressure increases, thereby progressively opening the bleed valve to increase the pressure applied by the servo-mechanism. Each rear wheel drives a generator 63, the outputs of which are applied across a pair of capacitors which differentiate the outputs to provide signals representing deceleration of the wheels which signals are supplied through a control amplifier 64 to the coil of a solenoid 46 having a plunger 45 connected to the end of the Bourdon tube so that resistance to straightening of the tube can be applied to reduce braking force and preventing wheel-lock and skidding.
