Title: Removal of forces in pre-tensioned or cost tensioned tendons in concrete prior to demolition
Inventor: TOLLAST ROBIN JOHN
IPC: E04G23/08
Filed: 1987-08-11
Abstract: When demolishing prestressed concrete structures consideration must be given to the large forces that exist in the steel tendons. Where the demolition is taking place remote from other buildings explosives may be used to destroy the structure. Where demolition is taking place within an urban environment explosives cannot be used. In the proposed method relaxation of the tensile forces is undertaken with the application of a voltage across the ends of the tendons. The heating of the tendons produces strain in the tendons which is of opposite sign to that caused by the original applied stressing. The demolition can than take place without the risk of dangerous release of prestressed forces. <IMAGE>

Title: Surge arrester
Inventor: DOONE RODNEY MEREDITH
IPC: H01C7/12
Filed: 1990-05-03
Abstract: A distribution class surge arrester comprises a core formed of distributed zinc oxide varistor blocks 2 aluminium blocks 3 acting as heat sinks and as spacers providing voltage grading and required arcing distances, and terminal blocks 4 held in face to face contact by means of a glass reinforced epoxy shell 5 which may be formed by winding a pre-preg onto the assembled blocks, (Figures 5-1 to 5-3, 6-1 to 6-5) and thermally curing under mould pressure within an evacuated mould (Figures 7-1.7-2). The core is housed within a polymeric shedded housing 6 which is formed by shrinking a heat-shrink shedded sleeve onto the core with a sealant provided in the interface of the core and the sleeve, and end caps 8 are sealed 9 to the ends of the structure thus formed. The all solid-state arrester is formed so as to avoid gaseous entrapments and voids within the core and between the core and outer housing 6. The physical strength of the arrester enables it to serve additionally as a stand-off support insulator in situations where conventionally separate arrester and support insulators were required. The outer housing 6 may alternatively be formed by stretching an elastomeric housing, introducing it onto the core and then releasing it, or by moulding a synthetic polymer housing directly onto the core. <IMAGE>
