Abstract: 1298815 Multiple-effect evaporators; removing droplets from steam UNITED KINGDOM ATOMIC ENERGY AUTHORITY 11 Dec 1970 [12 Dec 1969] 60874/69 Headings B1B and B1T In a modular multi-effect evaporator, suitable for the production of fresh water from saline water, a number of horizontal sheets 6a, 6b, . . of wire mesh remove liquid droplets from the vapour flowing through passage 8 from the chamber 5 of one effect to the heating compartment 3 of the next effect. The sheets of wire mesh are arranged in tiers and, together with vertically - inclined baffles 7, present parallel flowpaths to the vapour stream. The disentrained liquid droplets, which drip from the undersides of sheets 6, are collected in channels 10 along the lower edges of baffles 7. The channels 10 are horizontally inclined to allow the collected liquid to run off into a sump (not shown). Extending through the heating compartment 3 of each effect are a number of long, vertical tubes 2 which are supplied with liquid from header 1, and flows in filmform down the interior surface of the tubes. The saline water-to-be-treated is fed to the header of effect A. Hot brine from chamber 5 of effect A is introduced into the header of effect B. The steam condensate collected in the compartments 3 is the required fresh water.

Patent GB-2024068-A (GB)
Title: Improvements relating to casting machines
IPC: B22D29/00
Filed: 1979-06-28
Abstract: To enable castings to be removed from a semi-permanent or sand mould or gravity die casting machine without the necessity for handling them manually or using lifting gear, the machine has a mould base supported for pivotal movement about a horizontal axis so that it can be inverted to eject castings downwards out of the mould base. The castings may be ejected by gravity alone, or ejector means may be provided in the die base to assist ejection. As shown, the mould base 8 is mounted on a carrier plate 15 supported by stub axles journalled on a body structure 1 of the machine. One stub axle 19 is driven by a hydraulic motor to pivot the carrier plate and thereby the mould base. A pneumatically-operated bolt, 27 on the body structure retractably engages with the carrier plate to lock the plate against rotation when the mould base is in the operative position. <IMAGE>

Title: Improvements in or relating to self-adaptive linear prediction filters
IPC: G10L19/08
Filed: 1979-07-11
Abstract: A form of self-adaptive linear prediction filter for use in speech communications, based on the PARCOR (partial autocorrelation) lattice structure of Itakura and Saito which conventionally employs a division process, in the correlation 2 Fig. 2, to update the PARCOR coefficient estimates for each stage. The performance of these division processes presents great difficulty where the PARCOR coefficient estimates are to be updated at frequent intervals particularly in an analogue implementation. In filters according to the present invention successive PARCOR coefficient estimates (Kp) in each stage of the lattice Fig. 3 are derived using a recursive relationship which requires no division processes in its implementation. <IMAGE>
Patent GB-2032244-A (GB)
Title: Non-combustible cigarette
IPC: A24F42/60
Filed: 1979-10-01
Abstract: A non-combustible cigarette includes a container shaped to simulate a combustible cigarette and defining a passageway therethrough. An absorbent member containing a nicotine mixture is disposed within the container and communicates with the passageway via a constriction, the device thereby being adapted to release vapors from the nicotine mixture into an airstream which is drawn through the cigarette and into a user's lungs by inhalation. The cigarette may have resilient flaps at each end of the container to seal the passageway and prevent evaporation of the nicotine mixture when the cigarette is not in use, and to open when air is drawn through the cigarette. The ends of the container may also be provided with moisture seals fashioned of porous plugs, which permit air flow through the cigarette, but expand upon contact with liquids and thereby prevent moisture from permeating the absorbent member. The shape of the absorbent member and the area of communication between the absorbent member and the passageway may be arranged so as to provide a release of vapors in a predetermined sequence of concentrations. The device may further be equipped with multiple absorbent members, thereby providing for the inclusion within the cigarette of two mixtures having incompatible characteristics. <IMAGE>

Title: Process for the extraction of tritium from heavy water
IPC: C01B4/00
Filed: 1980-01-10
Abstract: A process for the extraction of tritium from a liquid heavy water stream comprising contacting the liquid heavy water with a countercurrent gaseous deuterium in a column packed with a water-repellent catalyst, preferably a Group VIII metal having a water- repellent gas and water-permeable coating of an organic polymer or resin, such that tritium is transferred by isotopic exchange from the liquid heavy water stream to the gaseous deuterium stream, passing the gas enriched in tritium from the column through for example a cryogenic distillation column for removing tritium therefrom, returning the gas lean in tritium to the column and obtaining a liquid heavy water output from the column, said heavy water being reduced in tritium content. Feed water is preferably purified before passing through the column, and the gas stream from the column is purified prior to separation of the tritium.

Title: Converter circuit employing pulse-width modulation
IPC: H02M3/28
Filed: 1980-08-28
Abstract: A voltage conversion and regulation system uses pulse-width modulation to vary the periodic energization of a tuned circuit 21 employed to drive a transformer and an associated rectifier. The tuned resonant circuit is periodically energized from a DC source at a fixed rate but for alterable periods of time during each cycle so as to produce in the tuned circuit an alternating current of fixed frequency for subsequent transformation and rectification into a DC voltage of predetermined, regulated level. A pulse-width modulator 42 is connected in feedback-loop fashion between the system output terminals and switch means 26, 28 employed to effect the periodic energization. Varying the length of time during which the switch means are activated in response to changes in the level of output voltage produces the desired regulating control. <IMAGE>
