Patent ES-2032960-T3 (ES)
IPC: B67D1/12
Filed: 1988-04-21
Granted: 1993-03-01
Abstract: A fluid pressure control valve and a fluid control system (such as for beverage dispensing) with such a valve has a beverage passage (3), pressure fluctuations in which are detected by a diaphragm (17) to displace a sensing member (15) axially against spring loading (23). Spring (23) reacts on thrust member (22) which is adjustable axially through a cam mechanism (25/26) to vary the biasing force of spring (23). A valve member (20) spring loaded at (21) relative to thrust member (15) normally closes an exhaust port (19) to an air or other gas passage (5) through which gas passes under pressure to be injected into the beverage from passage (3). An increase in beverage pressure in passage (3) displaces sensing member (15) to increase the spring biasing (21) on the closure member (20) and reduce the proportion of air which can escape to atmosphere from passage (5) through exhaust port (19) to provide an increase in air flow into the beverage. A reduction of pressure in passage (3) reduces the spring biasing (21) to permit a greater proportion of air to escape from passage (5) through exhaust port (9) and thereby reduce the proportion of air which is introduced into the beverage. The control valve can include a temperature sensitive unit responsive to temperature of beverage in passage (3) and which reacts to adjust the force of biasing spring (21) independently of pressure in the passage (3). Plunger (51) can be depressed manually to close the exhaust port (19) temporarily and thereby maintain maximum air pressure in the passage (5).

Abstract: In a method for charging rechargeable batteries, especially lead-acid accumulators, preferably in a maintenance-free, sealed design, it is intended that the permissible gassing pressure inside the battery cells should not be exceeded, irrespective of the characteristic used. After reaching an upper limit voltage (UoG) of the battery, below the gassing voltage, the charging current (I) is therefore reduced to a lower value until the falling battery voltage has reached a lower limit value (UuG). In consequence, the charging current (I) is raised again to the upper value which falls slightly with increasing charge. This pulsating charging method is continued until the charging current with the lower value reaches a specific switch-on time (tu,max). Thereafter, subsequent charging takes place with the lower value of the charging current (I) for a predetermined subsequent charging time (tN). <IMAGE>

Abstract: Methods of preparing storage stable components useful for metathesis bulk polymerization of cycloolefin monomers are provided. These components contain cycloolefins with norbornene-functional groups and cocatalysts activated with a halometal compound. In these methods, the cocatalyst is completely formed before the halometal activator is added to prevent the formation of unwanted hydrogen halides, which catalyze undesired crosslinking reactions which destabilize the cocatalyst component. Bulk polymerization systems are provided wherein these storage stable cocatalyst components are paired with catalyst components that together form the complete metathesis catalyst system. For some embodiments, storage stability is aided by the removal of water.

When the pixels are illuminated, each generates a two-dimensional optical catastrophe image diffraction pattern whereby the total image diffraction pattern of the grating is optically variable but structurally stable. The invention further provides a diffraction grating of reflective or transmissive lines, comprising a multiplicity of diffraction grating regions which are at least partly separated by multiplicity of grating free regions. Each grating free region has a dimension which is at least large enough to be resolved by the human eye, the total grating free areas not exceeding about 20 to 50% of the total area of the grating. The disclosed diffraction grating is useful as a security device for currency or credit cards.
