摘要:
The invention relates to a roller-screen arrangement having covering roller screens which are arranged axially one beside the other and can be jointly rolled up onto, and unrolled from, a winding roller, wherein the free ends of the covering roller screens are oriented in opposite directions. The covering roller screens can thus be jointly rolled up onto, and unrolled from, the winding roller, wherein furthermore, in the unrolled state, a distance A is formed between the covering roller screens. A cavity is created between the covering roller screens, and at least one intermediate roller screen is provided in this cavity in order to cover gaps between the covering roller stir screens arranged axially one beside the other. When the covering roller screens are opened and closed, the intermediate roller screens are taken up and let down and picked up again in accordance with the shortening and lengthening of the covering roller screens.

A ring-shaped network (RN) which is an offering network is inserted into a subscriber line region of a switching equipment (VE). A gate (GWE) is arranged in one (AEI) of the acceptance devices of the respectively accepting n subscriber line equipment (SLM) and signalling and message transmission procedure matching is done in the gateway means. The coupling to the ring-shaped network (RN) occurs through a ring-coupling (RCB) to which a gateway apparatus (GWE) and an external acceptance device (AEE) which contains a matching device (APE) and a plurality of subscriber line equipment (SLM) are connected. The matching device (APE) provides the signalling and information transmission procedure matching. For example, ISDN subscriber equipment (SE) are connected to the subscriber line equipment (SLM) via central office lines (ASL). The communications system is operated, administered and monitored either centrally by the switching equipment (VE) via an operating terminal arranged in the switching equipment (VE) or divided into two network regions, either subscriber line region/switching center or switching eqipment network/ring-shaped network by the switching equipment (VE) and/or by the gateway apparatus (GWE).
摘要:
A communications system with communications terminal equipment provided with prescribed functions that are defined and controlled by a communications installation by information transmission. An identical parameter-controlled program for all communications terminal equipment connectable to a communications installation is stored in the program memory of the communications terminal equipment. All functions that can be allocated to the different types of communications terminal equipment are realized by this program. The functions provided for the respective communications terminal equipment are allocated and controlled by parameter data stored in a data memory. On the basis of an initialization in the communications terminal equipment or in the communications installation, the parameter data are transmitted for the first time to or updated at the respective communications terminal equipment by the communications installation. In a communications system fashioned in this manner, the terminal-associated, flexible allocation of functions and procedures to the respective communications terminal equipment is preserved despite the displacement of switching-oriented and operations-oriented functions into the communications terminal equipment, which means a dynamic relieving of the central controller of the communications installation.
摘要:
The invention relates to a cooling goods presentation refrigerator for presenting refrigerated goods or frozen goods, with a vertical access opening to the goods chamber that is subdivided into vertically superposed compartments. The current of cooling air is conducted out of the head part directly into the shelf compartments arranged underneath it, during which the cooling air flows from the top downward through one shelf compartment after the other and from the lowest shelf compartment it is trapped in a collection chamber arranged underneath it and subsequently prepared by the cooling unit for the next circulation. The head part of the goods presentation refrigerator comprises an air-permeable separating wall against the adjacent shelf compartment. The shelf compartment bottoms are air-permeable, so that the current of cooling air can flow successively downward through the shelf compartments.

Merchandise display cabinet for showing refrigerated or frozen merchandise that features a vertical opening for accessing the merchandise space, which is subdivided into shelves arranged vertically on top of each other. The front side of the merchandise space accessible to the customer can be closed with transparent, horizontally-moving doors that in each case have a vertical marginal area through which the merchandise space is lit. The lighting installation is arranged outside of the merchandise space.
摘要:
A process for producing roller blinds includes defining a plurality of shapes for the completed roller blind in a continuous material band. The band has a uniform width and edges of the roller blind are defined between the longitudinal edges of the material band. Separating strips are defined in the material band between adjacent edges of the devices. The individual devices are removed from the continuous material band by separating the material band along the separating strips.
摘要:
The zirconium cladding of a coolant-displacement rod of a nuclear reactor is precollapsed in the zirconium oxide stack of pellets which supports the cladding. Current is conducted through the cladding in an atmosphere at reduced pressure containing residual oxygen, to heat the cladding to a temperature at which its yield strength is reduced. Then, while the rod remains at this temperature, it is subjected to isostatic pressure which collapses the cladding uniformly. The formation, by reason of exposure to neutron flux, of a long unsupported gap in the cladding which might be collapsed under the pressure of the coolant is precluded. In addition, the rod retains its symmetry. The outer surface of the cladding is oxidized, facilitating the movement of the rod into its thimbles of the core and improving the resistances of the cladding to reaction with the coolant.
