Title: Microporous protective sheet
IPC: D06M10/00
Filed: 1979-07-11
Abstract: A flexible, microporous, non- water soluble, non-skin-toxic film or sheet for use in protective garments such as divers suits and foul weather suits is characterised by a thickness in the range of 12.5 mu  to 12.5 mm, a pore density of 100 to 1,000 pores per cm<2> and a pore diameter in the range of 2 to 100  mu .

Title: Electric traction current-collector
Inventor: FERGUSON IAN CAMPBELL
IPC: B60L5/20
Filed: 1981-10-22
Abstract: An electric traction current-collector, such as is described in United Kingdom Patent Specification No. 1 374 972, has a carbon current-collector block (1) housing a rupturable tubular container (7) for air under pressure applied through a pneumatic control system for a pantograph or other carrier so that loss of air pressure due to rupture of the container causes the current-collector block to be retracted.

Title: Electroacoustic transducers
Inventor: LERWILL WILLIAM EDWARD
IPC: G01V1/02
Filed: 1982-07-01
Abstract: Method and apparatus for the generation of low frequency acoustic energy such as may be employed in carrying out seismic surveys in marine environment. In imparting an acoustic energy pulse into a body of water, a planar electroacoustic transducer having parallel transducer plates (30, 32) is employed. The transducer plates have conforming electrical conductive paths (30a... d, 32a... d). An impulse of opposed current flow is applied to the conductive paths to produce an electromagnetic field between the conforming paths which forces the transducer plates apart, generating an acoustic impulse having a center band frequency of less than 350 hertz. The wave length of the acoustic impulse at this frequency is less than twice the major planar axis of the transducer. The conductive paths may be formed of elongated conductors which are oblong in cross section and cover most of the radiating surface of the transducer. <IMAGE>
