Title: An electrolytic method of drinking-water purification
Inventor: BAKHIR VITOLD MIKHAILOVICH
IPC: C02F1/467
Filed: 1991-07-24
Abstract: Water is made to flow through the anode chamber 1 of a diaphragm electrolyser having an ultra filtration diaphragm 4, then through a body 8 of carbon granules and finally through cathode chamber 3. Electricity consumption is from 100 to 1500 coulombs per litre depending on requirements. The anodal processing achieves complete decontamination, destructive oxidation of organic contaminants, viz. phenols, formaldehyde, phosphororganic, metal-organic and serous compounds. The destructive oxidation products are non-toxic. They include water, carbonic acid gas, carbonic acids and other harmless substances. The cathodal processing achieves hydrolytic disintegration of organic impurities, viz. amino compounds, nitrils, certain phosphororganic insecticides, neutralisation of heavy-metal ions - lead, mercury, selenium, chromium and others, loosening of the structure of water, and enhancement of its biological qualities. The substances produced by hydrolytic reactions of organic compounds are non-toxic. <IMAGE>

Patent GB-2259164-A (GB)
Title: Transparent system interrupts with integrated extended memory addressing
Inventor: KARDACH JAMES
IPC: G06F9/48
Filed: 1992-07-30
Abstract: A dedicated memory area is provided on a microprocessor system for storing a customizable system interrupt service routine, and processor state data at the time of interruption. The dedicated memory area is normally not mapped as part of the main memory space, thereby to keep it inaccessible to the operating system and applications. An unmaskable system supervisor interrupt having higher priority than all other maskable and unmaskable interrupts is added to the CPU interrupts. The dedicated memory area is mapped, 102, as part of the main memory space, and extended memory addressing limits are overridden, 107, when the CPU is interrupted by this added interrupt. A RESUME instruction is added to the CPU instructions to provide recovery of the CPU to the state before it was interrupted. The extended memory addressing limits are restored, 114, and the dedicated area un-mapped, 116, when the CPU is restored by the RESUME instruction. As a result, a system integrator or OEM may provide transparent system level interrupts with integrated extended memory addressing that will operate reliably in any operating environment, and be able to address the entire physical address space and have access to all system resources in a stand alone manner during the interrupt. <IMAGE>

Title: Gun launchable sensor
Inventor: HOLLIDAY JOHN HAROLD
IPC: F42B12/62
Filed: 1993-02-23
Abstract: A sensor of the sonobuoy type is packaged in a shell-like housing (7) so that it can be deployed by firing from a gun in the manner of a round of ammunition. As the shell enters the water, an input sensor (10) causes a package (8) containing the sonobuoy to be ejected from the shell. The package sinks, and at a predetermined depth, a pressure sensor causes the sonobuoy to be ejected from the package, the sonobuoy float inflating and rising to the surface. The sonobuoy may include a receiver for GPS or OMEGA transmissions which allow its point of deployment to be positively ascertained even though it is out of visual range. The hydrophone may be responsive to phenomena other than sound and may include or be replaced by an acoustic or other radiation-producing source, or may be omitted entirely.

IPC: G01N17/02
Filed: 1993-09-23
Abstract: A method for producing electrochemical impedance spectra. Spontaneously occuring coupling current noise between an array of electrodes which may be of substantially the same material is detected. A time domain record of the detected current noise is stored and the time domain record of the detected current noise is transformed to the frequency domain. Spontaneously occurring potential noise between the array of electrodes and a further electrode is detected. A time domain record of the detected potential noise is stored and the time domain record of the detected potential noise is transformed to the frequency domain. The frequency domain current noise and potential noise transformations are then transformed to the impedance domain to produce the required electrochemical impedance spectra. <IMAGE>

IPC: B65B9/02
Filed: 1992-10-09
Abstract: A travelling two-ply web of infusion packages (11) is cut transversely by rotary cutting means (50) to form individual packages (1) which are attached to a styrene cover web (70). The packages (1) and web (70) are fed at the same speed rotary attachment means (100) comprising heated welding tips (102) co-operating with an anvil roller (90).

Abstract: An apparatus and a method for attaching articles (11) to a plastic bag wall (10') and particularly for attaching flat articles (11), such as coupons, cards, packets, samples, etc., to an inside wall of a panel of the bag and at different locations thereon. The articles (11) are attached by feeding a bag-forming film sheet (22) of plastic material to an article insertion station (24) where the plastic sheet (22) passes about a nip roll (26). An article transfer mechanism (30) transfers articles (11) from a discharge end of one or more supply magazines (29) to two or more support surfaces (42) at an article insertion station (40). These support surfaces (42) are aligned with distinct sections of the bag-forming film sheet (22). An attaching film sheet (28) is fed over a support roll (27) which is in frictional rotational contact with the nip roll (26) with the attaching film sheet (28) aligned over the distinct sections of the bag-forming film sheet. The nip roll (26) is moved in the direction towards the support surface (42) to grasp a leading edge (11') of an article (11) positioned on the support surface (42) to position same between the bag-forming film sheet (22) and the attaching film sheet (28) along the distinct sections. The two sheets are then sealed together with the article captive therebetween. The composite film can then be fed to a bag-forming station. <IMAGE>
