Abstract: A method for determining spatial service performance of urban public welfare service facilities is provided, in which basic data of the public welfare service facilities in a research area is collected to determine the spatial service basic performance; and a location factor of each of the urban public welfare service facilities is determined according to distances between the urban public welfare service facility and various urban centers, and finally the spatial service performance of the urban public welfare service facilities of the whole research area is determined. The method is simple in process, amount of the data is small and the data is convenient to collect. The data is collected from core business data of a natural resources and planning department, and thus the spatial data of various types of public welfare service facilities can be determined stably.

Abstract: A lockset is actuable by pivoting a handle about a longitudinal axis of the lockset by rotating the handle and by pivoting the handle about an axis transverse to the lockset axis, such as by pushing or pulling. The lockset includes an inside handle and an outside handle, each associated with an independent mechanism, each of which can independently actuate the lockset. A locking mechanism prevents actuation of a first one of the independent handle mechanisms without affecting operation of the other handle mechanism. Upon actuation of the other handle mechanism, a retractor engages a surface of the locking mechanism and removes it from engagement with the first locking mechanism. An adjustment ring has a first configuration that centers the lockset in a door having a first standard thickness and a second configuration that centers the lockset in a door having a second standard thickness.
