Abstract: The line trunk groups, which are connected to the doubled switching network via two time-division multiplex lines each and exhibit, among other things, one group switch each and one local group processor each are associated with one another in pairs. In preparation for a switching to standby of the central switching network and associated central processor, the subscriber lines and/or junction lines of the two line trunk groups in each case associated with one another in pairs which are connected to a first one of these two line trunk groups can be switched from the group switch of the first line trunk group to that of the partner line trunk group, that is to say of a second line trunk group - and conversely, in which arrangement their local group processor also takes over all control functions (for the local group processor of the first line trunk group). The local group processors of all first ones of the two line trunk groups in each case associated with one another in pairs are connected via the switching network taking up operation for the impending switching to standby to their corresponding central processor and loaded by the latter with all the required software. In the meantime, the switching operation is continued with the second local group processors in each case until the loading procedures have been concluded and switching to standby takes place from the central switching network and central processor and the temporary switching-over of the subscriber lines and/or junction lines within each of the pairs of line trunk groups is cancelled again.

Abstract: 1453037 Door raising mechanism CRAWFORD DOOR EUROPEAN CO AB 20 Dec 1973 [3 Oct 1973] 59131/73 Heading E2M [Also in Division H2] A door raising mechanism comprises a motor 3 which operates, via drive band 7, clutch disc 10, a chain 18 and a door drive chain 31, and includes a device 15 which acts in response to the revolutions of a shaft 9 to actuate a magnetic brake 16 when the revolutions go outside a predetermined range. A belt pulley 8 rotatable on shaft 9 is pressed by spring 11 against clutch disc 10 and acts as a safety mechanism to prevent damage to the motor. A mechanism comprising an operating arm 39, a spring biassed rod 23 and a coupling 22 can isolate drive gear 19 from shaft 20 to allow manual operation of the door. When the manual position is selected a switch 38 operates to isolate the motor. In addition to door drive chain 31, shaft 20 drives chain 33 which rotates a threaded spindle on which dogs 36 move to actuate a limit switch 37 in the upper and lower positions of the door. The magnetic brake is operated by device 15 should the shaft 9 increase in speed above a predetermined level due to a fault in the mechanism, or decrease in speed by reason of the door striking an obstacle. The brake can be operated manually.

Title: Visual display device with fluorescent dye-doped edge-illuminating emitter panel
Inventor: WU WEI-YU
IPC: G02F1/13357

Granted: 1994-07-12
Abstract: VISUAL DISPLAY DEVICE WITH FLUORESCENT DYE-DOPED EDGE-ILLUMINATING EMITTER PANEL            ABSTRACT OF THE INVENTION     A light emitting panel is formed of a transparent plastic substrate doped with fluorescent dye which absorbs incident light through a relatively large surface area and emits light of a longer wavelength out through one edge. The  incident  light  may  be  ambient or  produced  by  a fluorescent  light  source.    The  edge  emitted  light  is optically coupled into an edge of a display panel, which may be a polymer dispersed liquid crystal display or a plastic panel having a display  surface  formed with an etched  or printed  pattern,  grating  or hologram.    The substrate materials of the emitting and display panels, as well as an optical adhesive which joins the edges thereof, preferably have an essentially similar index of refraction which is larger than that of air causing light propagating through the panels to be internally reflected and exit the structure only through the pattern on the display surface. The display panel is preferably transparent in the absence of light incident on the emitting panel, and produces a display visible from only one direction upon application of incident light. The display panel may be constituted as a center-high-mounted stop light for an automotive vehicle.

Title: Modular expandable digital single-stage switching network in atm (asynchronous transfer mode) technology for a fast packet-switched transmission of information
Inventor: LOBJINSKI MANFRED
IPC: H04L12/54
Filed: 1989-12-21
Granted: 2000-11-14
Abstract: A modular expandable digital single-stage switching network in ATM (Asynchronous Transfer Mode) technology for a fast packet-switched transmission of information, having a pre-switching module, a pre-switching being carried out only with respect to the matrix column, but not with respect to the matrix output, and the number of expansion inputs and the number of first outputs of the pre-switching module being 1/L, namely N, of that of the expansion module. The module contains a single FIFO which can read in 2N packets simultaneously and read out N packets simultaneously and, to avoid so-called packet overtaking, the chronological sequence of packets arriving in each case on one of the n first input lines of a pre-switching module is replaced from case to case by a spatial ordering on the N first output lines of the pre-switching module. A header information filter processes only a part of the header information of the data packets for switching the packets to the respective switching module column. In addition, there are provided for each matrix column a further pre-switching module and a final switching module, which carries out a final switching to the matrix output, the first outputs of said pre-switching modules being connected to the respective inputs of the final switching modules. The final switching modules have no expansion inputs and no expansion outputs. The header information filter of the final switching module processes another part of the header information for the final switching to a matrix output.

Title: Hot water supplying system
Inventor: SHIMIZU TOMOYUKI
IPC: F24D19/10
Filed: 1989-12-22
Granted: 1992-05-19
Abstract: ABSTRACT    A hot water supplying system is adapted to be connected to hot and cold water sources to mix the hot and cold water for discharging the mixed water.  The system comprises a mixing chamber having a mixing valve movable therein to vary the mixing ratio of the hot water to the cold water, and a controller at which an intended water temperature is selected in accordance with a temperature scale provided thereat.  The controller is operatively connected to the mixing valve so as to move the same into a proper position of discharging the water at the selected temperature.  The mixing valve is given a temperature-responsive characteristic to be capable of self-adjusting its position independently of the controller in such a way as to adjust the water temperature in an open loop control manner at the start of discharging  the water.  An initial compensation mode is provided in the system to monitor the water temperature and determine a deviation between the monitored temperature and the selected temperature.  When the deviation exceeds an acceptable level, the controller responds to reassign the temperature scale with the mixing valve position in order to reduce the deviation to the acceptable level and therefore to provide a consistent relation between the water temperature and the selected temperature, whereby compensating for variations in temperature and pressures of the hot and cold water sources available at differing installation sites.
