    Abstract: 11,375. Cross, A. J. May 15. Spectacle lenses.-A bifocal lens is made from two members of the same contour, the shortdistance-member 11 being complete and the longdistance component 12 being cut away so that the member 11 is used by itself for reading &c. The two parts are cemented together and further held by straps 14, 15.

    Abstract: 17,820. Cross, A. J. July 28. Spectacle lenses. - In multi-focal spectacle lenses, the optical axes 5, 6 of the minor segments 2, 3 pass through the middle points of the inner edges of such segments and are decentred with respect to the axis 4 of the principal lens 1. The principal lens may have two or more minor lenses superposed upon it in this way.

    Abstract: A compressor comprising a cylinder (1) with an axially reciprocating piston (5) which compresses gas in the cylinder. At least two circumferential rows of flat fan spray nozzles (10) spray water into the cylinder during compression. Each nozzle is arranged such that the spray is in a plane substantially parallel to the axis (4) of the cylinder and is directed towards a central region of the cylinder.
