Title: Method and apparatus for disseminating standard time information
Inventor: WESTPHAL ROBERT
IPC: G04R20/06
Filed: 1994-04-18
Abstract: A method and apparatuses for disseminating an item of terrestrial standard time information (12) to radio clocks (18) which can be operated world-wide and which directly display the correct local time (16) rely for information transmission purposes on a network of satellites (13) with low orbits (14), referred to as LEOS, for example as are planned for world-wide person-related direct telecommunication connections. Each satellite (13) receives an item of terrestrial standard time information (12) from a control transmitter (11) directly or by way of a reference satellite (13.0) which is in a better reception position, and possibly from the control transmitter also an item of synchronous information (17) for the instantaneous, positiondependent time zone shift of the local time (16) which is to be sent back from the satellite (13) to a limited region of the earth. The local time may additionally contain information about the association thereof with a given time zone (15) so that, for a radio clock (18) which is operated in a given time zone (15), it is possible to ascertain from that item of additional information relating to the received local time (16) - or from the Doppler change in the local time (16) - where the orbit (14) is in relation to the reception time zone (15). If the received local time (16) is not directly associated with said time zone (15), then in addition to the decoded local time (16) a corresponding time zone shift is also to be taken into consideration in the display. The time zone shift can be derived in an association means (23) within the radio clock (18) in order to monitor the display means (20) which is operated by the autonomous time-keeping circuit (19) and if necessary correct the instantaneous time display in proper relationship with the respective time zone.

IPC: F16C19/38
Filed: 1992-11-27
Abstract: The present invention relates to a cutter of a boring head, and also to a hub constituting a part of the cutter, and a method of manufacturing a hub. The cutter (10; 10') is rotatably mounted in a saddle in the boring head. A roller bearing means is located between the shaft (11; 11') and the hub (18; 18') of the cutter. In order to improve the bearing capacity of the cutters, the outer races (17; 17'a, 17'b) for the rollers (15; 15'a, 15'b) of the roller bearing means, are integral with the hub. In the method of manufacturing of a hub (18; 18'), those portions of the hub which are not to be hardened are left unfinished or covered by a layer that prevents carburization. The hub can then have different properties in different portions in order to comply with tolerances and specifications.

Abstract: An electrostatographic single-pass multiple station multi-colour printer for forming an image onto a web (12), eg of paper, is described. The printer comprises a plurality of toner image-producing electrostatographic printing stations (A, B, C, D, E) each having rotatable endless surface means (26) such as the photoconductive surface of a cylindrical drum (24) onto which a toner image can be formed. The paper web (12) is conveyed in succession past the printing stations (A, B, C, D, E).    The speed and tension of the web (12) is controlled while it is running past the printing stations (A, B, C, D, E).    Guiding rollers (36) which determine for the web (12) wrapping angles (.omega.) of about 15° about the drum surface.    A corona device transfers the toner image on each drum onto the web (12). The corona device, the wrapping angles .omega. and the web tension are such that adherent contact of the web (12) with the drum surface (26) is such that the moving paper web (12) controls the peripheral speed of the drum in synchronism with the movement of said web. Slippage between the drum surface (26) and the paper web (12) is thereby eliminated, enabling accurate registration of superimposed images on the paper web (12).
