摘要:
The present invention relates to a process and also to a service computer, a switching center, terminals, program modules and memory means with program modules for handling incoming telephone calls for a subscriber line (VA1) of a telecommunications network (PSTN) during an online data-network session blocking the subscriber line (VA1). In this process a terminal (TERA) sets up a connection (VA11, VA1, VPOP1) to an online data-network access device (POP) via the subscriber line (VA1). Thereupon the online data-network access device (POP) sends current access data to the terminal (TERA), which the terminal (TERA) signals to a service computer (SCP) of the telecommunications network. If a switching center (SW1) of the telecommunications network then detects an incoming call destined for the subscriber line (VA1), the switching center (SW1) then signals the fact that this call is waiting to the service computer (SCP) which supplies at least one predetermined service for the purpose of processing the incoming call. The service may, for example, consist in a message being sent to the terminal (TERA), in which attention is drawn to the incoming call, or in the incoming call being forwarded to an alternative destination (TELA2).
摘要:
A manually actuated self-collecting parking meter includes a single lockable coin insertion device for receiving a range of available coin diameters. A coin checking device is arranged to receive one coin at a time from the insertion device and is placed in operation by turning a rotary locking handle. A parking time period display mechanism is arranged to be set based on the coin inserted into the checking device when the handle is rotated. The rotary locking handle can be rotated in either direction up to a stop for loading a force accumulator which automatically drives an operating mechanism for effecting the operation of the coin checking device and the setting of the display mechanism. For proper phase control of the operating mechanism, a closing segment and an operating segment are provided which uncouple the operating mechanism when the rotary handle is completely rotated so that the automatic operation is carried out.

A mount for a record player with variable antivibration controls that make it possible for the user of the player to separately establish an optimum antivibration setting depending on the conditions of the specific surface that the player is resting on and on the overall acoustical conditions with respect to footstep and acoustical feedback.
摘要:
A device for testing the magnetic properties of coins in coin operated apparatus such as parking meters, used in conjunction with a coin diameter testing device. The device includes a double arm rocker lever provided on a side wall of a coin guiding duct. A first arm of the rocker lever is equipped with a permanent magnet and the latter extends through an opening of the side wall into the range of a coin which has been inserted into the coin guiding duct and which temporarily rests on a coil support. A second arm of the rocker lever includes a locking bracket which can be controlled so as to be in and out of engagement with a testing segment required for the test for determining the diameter of coins.
摘要:
Coins inserted into a parking meter are tested as to diameter, the presence of one or more holes and the content of ferromagnetic material. In the latter test, the coins are transported through a coin transport channel extending intermediate a coin-insertion location and a coin receptacle. The channel has a breadth which exceeds the thickness of the coins to be processed by an amount permitting coins passing through the channel to shift in direction transverse to the direction of their travel. A magnet arrangement attracts magnetically attractable coins into contact with a wall of the channel as such coins pass through the channel. A sensing arrangement controls the setting of a parking time in dependence upon whether coins passing through the channel are attracted into contact with the wall. The sensing arrangement includes a sensing member which extends into the coin transport channel so positioned and mounted as to be displaced to a predetermined position by a coin which during its travel is being magnetically held against the wall. The setting of a parking time is prevented unless the sensing member is caused to assume the predetermined position.

An electric motor (10) for a machine tool or the like. The electric motor (10) is provided with a shaft (12) on which an encoder disk (15) is arranged. A first bushing (17) is provided and is connected to the encoder disk (15). The encoder disk (15) is arranged with a sliding fit on the shaft (12), and rests on a stop in the axial direction. A second bushing (18) is provided, which is arranged adjacent to and at a distance from the first bushing (17) on the shaft (12), and is arranged with an interference fit on the shaft (12). A compression spring (19) is arranged between the first bushing (17) and the second bushing (18) such that the first bushing (17) is pushed against the stop.

A method for distilling ethanol from a mash includes feeding a fluid to a first distillation column. The fluid and a distillate of the first distillation column are delivered to a second distillation column. The fed fluid and/or distillate of the second distillation column is/are purified in a first and/or last step of the method by a membrane separation process.
摘要:
Disclosed is a method for distilling, e.g. ethanol from a mash or must. According to said method, a fluid (1) that is fed to a first distillation column (stripper, 13) and a distillate (4) of the first distillation column (13) are delivered to a second distillation column (rectification column, 14). The fed fluid (1) and/or a distillate (7) of the second distillation column (14) is/are purified in a first and/or last step of the inventive method by means of a membrane separation process.
