Abstract: In a zoom lens system in which all or some of the lens components excluding the front fixed lens component are axially moved for taking a close-up photograph, a focusing lens group is axially moved in response to movement of a zooming lens group to maintain the resultant image position always in a stationary image plane. The interconnection between the focusing lens and the zooming lens is made through a mechanical or electrical control means which controls the movement of the focusing lens with reference to the movement of the zooming lens in accordance with a predetermined relationship therebetween.

Abstract: A gas cooking range of the smooth top type has four burners positioned under a single plate of heat-resistant glass/ceramic material; and a single igniter and safety control assembly is centrally positioned between the burners. The supply of gas to each of the burners flows through an ignition chamber where it is ignited, and it then flows through a combustion tube to a combustion chamber, where combustion is completed. Some air is mixed with the gas at the fuel supply control valve, and additional air is supplied through the ignition chamber. The burning gas mixture then flows through the combustion tube to the combustion chamber at the entrance of which an additional quantity of air is added to provide the remainder of air necessary for complete combustion.

Abstract: A tracked vehicle switch assembly is operatively connected between a single main track and a pair of diverging tracks for selectively diverting a vehicle moving along the main track to one of the diverging tracks. The switch assembly includes first and second track sections having first abutting ends, and second ends respectively connected to the main track and the pair of diverging tracks. The first track section is thus a continuation of the main track, while the second track section is a continuation of the pair of diverging tracks. The abutting ends of the first and second track sections are operatively connected to a moving device which simultaneously moves these ends in opposite directions between two extreme positions, in substantially the same plane, thereby to selectively align the first track section with the tracks of the second track section in order to selectively direct a vehicle on the main track to either of the diverging tracks.

Abstract: Air conditioning systems particularly suitable for large buildings located where water is not available for evaporative cooling to provide a heat sink. The condensate from the conditioned air is collected at the cooling and dehumidifying coils and is used as make-up water for one or more evaporative cooling towers which act as the heat sink. One of the cooling towers provides cooling solely by conduction with outside air. Air is exhausted from the conditioned space through one of the cooling towers so as to utilize the evaporation of the condensate in the low temperature and low relative humidity air. The invention also provides for improved operation and efficiency in systems without regard to utilizing condensate for evaporative cooling.
