Patent ES-316250-A1 (ES)
Title: Production of chlorine dioxide
IPC: C01B7/03
Filed: 1965-08-07
Abstract: ClO2 and Cl2 are produced by continuously adding an alkali metal chlorate and chloride and a strong acid to a reaction vessel, maintaining a partial pressure of water such as to ensure crystallization of the alkali metal salt of the acid within the vessel, and continuously withdrawing the product gases and solid. The acid may be H2SO4 or H5PO4 and the alkali metal may be Na, K or Li. The chlorate and chloride may be added dry or as solution, separately or together, in a ratio of 1 : 1 to 1 : 6 respectively. H2SO4 used may be above 100%. The reaction mixture produced may be 0.005-3 M in chlorate, 0.001-2 M in chloride, and less than 6 M in H2SO4, and may be at a temperature of - 25 DEG to + 100 DEG C. The partial pressure of water may be maintained by means of a water jet eductor (which produces a partial vacuum and also dissolves the ClO2 and Cl2), or by using a stream of inert gas, e.g. air or N2. Liquid effluent withdrawn from the vessel and wash water may be recycled. The crystals produced may be, for example, NaHSO4, NaHSO4.H2O, <FORM:1056790/C1/1>

Patent ES-358538-A1 (ES)
Title: Address examination mechanism for use in a system operating with dynamic storage relocation
IPC: G06F13/34
Filed: 1968-09-26
Abstract: A data processing system comprises a dynamic address translation device, co-operating with a stored table of relocated addresses corresponding to logical addresses, to gate for addressing a store the relocated address corresponding to an interrogating logical address in response to an " equal " comparison of the latter with a stored logical address. A multi-processor or multi-programme timesharing system can transfer pages of information between a disc backing store and a main core (or transistor) store as necessary. An " active " store (transistor type) includes respective predetermined locations holding the main store addresses of the latest instruction (viz. an instruction counter), first operand and second operand. When the main store is to be addressed using any of these addresses the address is supplied on a bus to a dynamic storage relocate unit which passes the low order portion to a main store address register and compares the high order portion to the contents of one of three " high " registers (according as the address relates to an instruction, first operand or second operand respectively, as indicated by which location of the active store was read out to get the address). If equal, the contents of the appropriate one of three " low " registers is gated to the main store address register to form the rest of the address. If unequal, machine status is saved in the active store, the high order four bits of the address are added to the middle of the highest order (8-bit) byte of the base address of a segment table in main store to address one entry of this table. This entry gives the base address of a page table in main store. Part of the appropriate " high " register is added to this base address near its low order end to address one entry of the page table, the contents of which are passed to the appropriate " low " register. The machine status is reloaded and the programme resumes. The appropriate " high " register has since been loaded from the bus mentioned so the comparison now gives equality and the appropriate " low " register (now contaming the relocated address) is gated to the main store address register. The active store also holds the last accessed segment table entry for each of the cases: instruction, first operand, second operand, in respective predetermined addresses.

Patent ES-430771-A1 (ES)
Title: Starter motors
IPC: F02N15/06
Filed: 1974-10-08
Abstract: A starter motor for an internal combustion engine including a pinion gear wheel assembly movable between a rest position and an operative position. The pinion gear wheel assembly is movable by a solenoid the armature of the solenoid being coupled to the pinion gear wheel assembly by way of a lever pivoted on the starter motor casing. The lever is in the form of a pair of resilient elements. The first resilient element is weaker than the resilient means which urges the armature towards its rest position, so that should the pinion gear wheel assembly be held in its operative position when the electromagnet is de-energised then the armature can be returned to its rest position flexing the first element. The second element supports the first element during movement of the lever assembly to push the pinion gear wheel assembly to its operative position. The combined strength of the first and second elements is such that if the pinion gear wheel assembly is held against movement to its operative position then both elements can be flexed by movement of the armature to its operative position. However, the flexed elements together provide sufficient force to move the pinion gear wheel assembly rapidly to its operative position when the impediment to movement of the assembly is removed.

Title: Parenteral liquid administration set with non-air blocking filter
IPC: A61M5/36
Filed: 1976-06-12
Abstract: A parenteral liquid administration set is provided which comprises flexible tubing, connection means with a parenteral liquid source at one end of the tubing, and means for connection to a blood vessel-penetrating member, such as a needle, at the other end of the tubing. In accordance with this invention, a filter, positioned in fluid communication with the bore of the tubing, comprises a housing, which carries first and second filter members in parallel flow position so that each increment of fluid flow through the tubing passes through one or the other of the filter members. The first filter member is hydrophilic, to permit the passage of solution under normal administration conditions. The second filter member is hydrophobic, to permit the passage of gas after wetting of the filter members. Accordingly, the filter members, which are closed from the exterior by the administration set, cannot airblock by the accumulation of air bubbles immediately upstream of the filter members.
