Patent GB-2280573-A (GB)
Title: Half duplex circuit for a local area network
Inventor: HUNG FRANCIS YUN-TAI
IPC: H04L12/433
Filed: 1993-07-31
Abstract: In a local area network, a half duplex circuit controls transmission over a two-wire link to a user terminal. Line drivers (20L, 20R) are selectively enabled via line circuit monitors (24L, 24R) whose outputs reset free-running counters (36L, 36R) during a signal burst in the one or the other direction. At the end of a signal burst, resetting of the corresponding counter is discontinued. This condition is detected by an RS flip-flop (28L, 28R) which generates a signal to disable the active line driver to ensure that only one line driver can be enabled at any one time. <IMAGE>

Title: Electrochemical separation of contaminant metal from scrap graphite
Inventor: HOLDERNESS STEWART GARFIELD
IPC: C25C5/00
Filed: 1993-08-13
Abstract: The contaminated scrap graphite is subjected to electrolytic treatment in an aqueous oxidising electrolyte. The electric current may be a directional electric current. The metal may be uranium and the scrap graphite may be that used in the casting of uranium fuel rods. The graphite body disintegrates in the electrolyte and the metal dissolves at an accelerated rate under the influence of the electric current. The metal can also break off from the graphite and may dissolve over a longer time period in the electrolyte. The scrap graphite may be placed in a basket 9, 11 having a base comprising a grille or perforations to allow particles to fall therethrough. The graphite so treated may therefore be separated from the electrolyte eg by filtering and washing. The graphite can be disposed of in a conventional manner rather than special means required for hazardous, radioactive materials. <IMAGE>

Title: Re-sealable mailer.
Inventor: PARKER JOHN EDWARD
IPC: B42D5/02
Filed: 1994-02-07
Abstract: An envelope and enclosure assembly comprises a document enclosure (2) sandwiched between a back panel (9) and a front panel (10) and assembled in continuous form. The continuous assembly is separable to form individual envelopes with associated enclosures; lines of separation, which may be in the form of perforations (19), may be provided for this purpose. The front and back panels (9, 10) of each envelope are joined together along all but one margin by lines of adhesive (15, 16). Along the remaining margin, the enclosure (2) is attached at one surface to one of the adjacent panels (9) by adhesive line (14) and its opposite surface is both attached to the other panel by adhesive line (17) and provided with adhesive means (7), which may be provided by double-sided adhesive tape, to reseal this side when desired. The adhesive means (7) does not extend the entire length of this side but stops short of the adjacent margins. In this way, adhesive from the adhesive means cannot seep out through the margins or through any perforation provided. Thus, the problem of seepage of adhesive causing envelope and enclosure assemblies to stick together, for example when stacked, or to stick to other articles or objects is avoided. <IMAGE>

Patent GB-2282523-A (GB)
Title: An electric kettle equipped with a filter
Inventor: BOIS BERNARD MARCEL
IPC: A47J31/14
Filed: 1994-10-06
Abstract: The invention relates to an electric kettle comprising a receptacle (3) for liquid, a spout (15) located in the upper part of the receptacle (3), a filter (25) located inside the receptacle (3) through which the liquid can pass when it is poured out of the receptacle (3) through the pouring spout (15). The filter (25) is located above the recommended maximum liquid level N in the receptacle (3) when the kettle is in its normal heating position. It is formed by a thin rigid plate comprising perforations and disposed in the pouring spout (15) transversally to the flow of the liquid. The perforated plate is mounted without being water-tight on the inner wall of the pouring spout thanks to the presence of outlet perforations (31). This reduces the flow of liquid across the filter and thus encourages the deposition of scale which reduces the active surface of the filter and therefore the outlet flow rate. <IMAGE>
