摘要： A net ball game employs a target comprising a partitioned net which provides three upper compartments for receiving an aerial projectile, e.g., a ball, and a lower compartment for receiving surface and/or aerial projectiles. The game is played on a flat arcuate playing surface having an enclosed area thereon for defensive play while the remainder of the field is used for offensive play.

摘要： A generator for generating a number of selected frequencies, comprising a pulse oscillator and a number of dividers which are connected thereto, a second number of dividers which also coupled to the former dividers via a switching network in order to adjust, under the control of the switching network, dividends which produce desired combinations of frequencies derived from the oscillator frequencies, in particular tone frequencies for tone pushbutton selection signalling, the dividers of the second group also being binary-to-digital signal converters to which first-order RC-networks are connected in order to suppress higher harmonics.

摘要： The present invention is a semi-rigid polymeric foam toy suitable for use as a toy building block. Its softness and larger size make it suitable for constructing wrestling mats and floatable rafts. Its lightness make lifting and throwing relatively easy for a child. The block has sockets and one integral projection for connecting to other blocks and the projection serves as a handle when the block is used as a throwing toy in various games.
