A pressure-sensitive lock for sliding windows and doors has rotatable eccentric cam means adapted to be mounted on the sash of a sliding window or door so as to engage the adjacent window frame when the cam means is rotated into the locking position. The lock also has a pressure block for mounting on the opposite side of the window adjacent the frame, such that when the cam means is placed in locking position against the frame, the sliding window is forced toward the opposite frame and the press...

A low reflection coating for windows. A coating of silicone rubber is applied on one surface of the window and preferably also on the other surface. Each coating preferably has a thickness of several wavelengths of light and has a minimum thickness of two microns. The coating is low cost and is suitable for large areas, for instance solar heat collectors. Reflectivity is reduced by approximately one-third. The coating has no relation to a quarter wavelength or any multiple thereof of incident li...

The present invention teaches an improved balance shoe. The improved balance shoe of the present invention comprises a balance shoe housing for retaining a sash in a channel of a window. The housing can have a base section and at least one side section. A pivot member can be employed by the housing.
