Title: Discouraging theft and unauthorised smelting of metal containers
Inventor: STANLEY ROBIN GEORGE
IPC: B65D25/00
Filed: 1986-11-14
Abstract: Theft of metal containers, especially aluminium beer kegs, is discouraged by incorporating a foreign substance into the structure of the container (44), e.g. in a cavity 46, which substance will contaminate the container material if the container is illegally smelted or will disrupt, e.g. by generating noxious gases, or otherwise adversely affect the smelting operation. The foreign substance may be another metal, water, exothermic powders such as manganese oxide or ferric oxide, rubber or plastics compounds or cementitious compounds. The foreign substance may be in a form where it can be secured by rivets to one end of the container (Figure 1) or accommodated in an annular cavity in a chine (Figure 2) or beneath a rolling ring (Figure 4). The foreign material may be embodied in an encapsulated preform, e.g. a cored aluminium wire 40. The presence of the foreign substance is not readily ascertainable by a container user. <IMAGE>

Title: Direction finding system
Inventor: ALCOCK ROBERT NICHOLAS
IPC: G01S3/30
Filed: 1990-04-11
Abstract: A direction finding system comprising a circular array of directional antennas (11 to 18) arranged equally about a common axis (19). To avoid having to provide a separate omni-directional antenna to derive a signal for analysis eg frequency determination, a signal is derived from at least that one of the directional antennas receiving the strongest signal. In order to do this the r.f. signals obtained from receiver sector units (21 to 28) are examined to see which contains the strongest signal and a single-pole multiple way switch (50) is controlled to select the output of the receiver sector unit providing the strongest signal and pass the signal to an Instantaneous Frequency Measuring unit (60) for analysis. Optionally alternate directional antennas (11 to 18) are grouped together and the switch (50) is controlled to select that group containing the stronger of the combined signals for analysis. <IMAGE>

Title: Improved hydrolytic stability in adhesive joints
Inventor: BOWDITCH MALCOLM RAY
IPC: C09K3/10
Filed: 1990-06-27
Abstract: Adhesive joint stability in the presence of water can be understood by adoption of a theory based on a partition coefficient where water partitions itself between the adhesive and an adherend to which it is attached. The stability of adhesive joints can be improved by adopting an adhesive or an adhesive matrix which possesses hydrophilic centres and low water absorption characteristics such that any water is preferentially attracted to the hydrophilic centres which are positioned away from the adhesive joint interface. The hydrophilic centres can in the case of a filled adhesive be supplied by using a filler with a higher surface free energy than the adherend. The adhesive may be epoxy resin-based and hydrolytic stability may be achieved by incorporating therein a component selected from a polyoxypropylene diamine hardener, a molecular sieve such as a zeolite, and a filler having a higher free energy than the adherend.
