Abstract: A calculator is defined by a user-interface centered around a last in first out stack of mathematical or logical objects, that is both visible and accessible to a user. Objects may be any of a number of different types, each type characterized by specific logical or mathematical rules. Calculator operations are provided that may be applied in a uniform manner to the objects, affecting either or both the internal composition of the objects or the external positions and number of the objects on the stack. Objects of different types are distinguished upon entry and in visible types by characteristic prefix and postfix symbols, and can be entered from a keyboard or created dynamically as the result of calculator operations.

Abstract: To transfer a call, the ringing signal is first of all supplied successively by the central control device (ZSt) to the individual terminals within a group of specially selected subscriber terminals according to the sequence defined in a list (L) in the customer data store (KD) until the call is set up. Following unsuccessful call attempts within this group, the ringing signal is supplied in a defined sequence to all the other terminals, with the exception of one or more which are correspondingly stored. This may be carried out in ascending order, starting with the lowest telephone number. This type of call transfer is normally implemented for external incoming call requests only. Each exchange line (L3) may be allocated its own individual group of terminals. <IMAGE>

Abstract: In order to produce a matt surface with high-solids coating systems, in particular in the case of ultraviolet cross-linking coating systems, in which case a high degree of anti-scratch resistance is to be ensured, a two-layer process is used with two coating application stations connected one behind the other. In the first coating application station a first coating occurs which serves essentially for achieving a desired anti-scratch resistance. In the second coating application station, the cover coating for obtaining the desired degree of matt is carried out, the layer thickness of the coating layer applied in the second coating application station being selected to be so thin that the means which produce the matt finish project out of the surface and give the desired degree of matt. <IMAGE>

Abstract: An electrically heated tubular body (10) fabricated of pyrolytic graphite in coaxial layers (12) serves to atomize samples for analysis by atomic absorption spectrophotometry. Radially extending graphite rods (14, 16) engage the medial portion of tubular body (10) at diametrically opposed locations and constitute electrodes for passing an electric heating current transversely through the body. Owing to the characteristic anisotropy of electrical and thermal conductivity of the graphite layers, a relatively high electrical resistance to the current and an even temperature distribution along the length of the tubular body result.

Abstract: To improve high speed durability or prevent tire ribs and/or blocks from being peeled off at high speed travel, a tread rubber member (80) whose outer surface is formed into a corrugation shape along the tire axial direction, when seen in cross section, is prepared to form a green tire so that radially convex portions (81) thereof may be located under tire circumferential grooves to be formed after vulcanization and radially concave portions (82) thereof may be located under tire ribs and/or blocks also to be formed after vulcanization. Since the rubber flow rate of the tread rubber member under the circumferential grooves is relatively large, when the green tire is vulcanized, the belt layers are conversely deformed into radially concave shape under the circumferential grooves. When the vulcanized tire is inflated with air or rotated at high speed, since the belt layers are returned to a flat shape and further the ribs and/or blocks are deformed into radially concave shape, it is possible to reduce a rise in temperature at the central portion of each of ribs and/or blocks.

Abstract: An interface adapter for use in combination with a commercial installation having a central refrigeration system with multiple compressors and refrigerated units and also having environmental apparatus for regulating the heating, ventilating and air conditioning of such installation. The refrigeration system has a local control apparatus for operating the system in response to local status signals and has remote control input ports for remote control of the system. A remote electronic controller adapted to receive the local status signals and to override at least part of said local control means operates the refrigeration system by generating an electrical control signal and a switchback signal indicating that the electrical control signal should be recognized. The interface adapter electronically isolates and interfaces the refrigeration system and the remote controller. The interface adapter includes a circuit responsive to the switchback signal for providing the electrical control signal of the remote controller with the remote input ports of the refrigeration system. The interface adapter may also include a circuit for providing at least one of the local status signals to the remote controller. As a result, the interface adapter permits a corresponding control signal to be provided to the remote control input port of the system even though the electrical characteristics of the remote control input port may be incompatible with one of the corresponding electrical characteristics of the control signal.
