Title: Magnetic tape device
Inventor: MAACK WERNER
IPC: G11B15/06
Filed: 1995-05-20
Abstract: The magnetic tape device comprises a magnetic tape, having a lacing position, and an arrangement for recognising the lacing position. Such magnetic tape can be laced only over this lacing position. As soon as such tape is inserted into a tape device, a backwards or forwards winding is performed, up to a marked and determined lacing position.  Two guide pins grasp behind the magnet tape and pull it out against a scanning arrangement. The magnetic tape is retained in this position by the mechanical influence of the pins.

Title: Communication network with monitoring device for checking connection capacity
Inventor: NAGEL PETER DR ING
IPC: H04L12/54
Filed: 1995-08-22
Abstract: The network transmits cells according to the asynchronous transfer mode. It has a number of stations and at least one monitoring device to check the connection capacity of virtual connections. The monitoring device includes at least one detector circuit (7) to detect at least one virtual connection of received cells. It also has a control circuit (5) to calculate the connection capacity of the virtual connection. When the value DAT minus SAAT is greater than SL the control circuit deletes the received cell. Otherwise, it conveys the cell.  The scaled earliest possible theoretical future time of the cell of the virtual connection is given by the equation DAT=max(X,STAT(Tn-1)-TS*TI*DT) where Tn is the future time and Tn-1 is the previous future time of a cell of this virtual connection. TS and TI are selectable constants. DT=Tn/TI-UT. UT equals the value SLUT(Tn-1) calculated at time Tn-1. SAAT =TS*Tn(modTI). STAT(Tn)=max(DAT,SAAT)+SI and X is less than or equal to SAAT. The control circuit (5) acts during a time cycle of a timer (8) to calculate the values SLUT(Ta)=Ta/TI and STAT(Ta=max(0,AT-TS*TI*DT). DT=(Ta/TI)-UT where Ta is the current time. The control circuit (5) stores the respective values SLUT and STAT as UT and AT in a memory arrangement (6). The counter (8) is provided to provide the times Tn-1,Tn and Ta.

IPC: H02J3/14
Filed: 1995-08-22
Abstract: A procedure for energy optimising in a distribution system has the actual power consumption of individual loads measured and if a least one load has to be disconnected, the selection is done one the basis of the measured powers. At least one load is thermostat-controlled and one or more switch-on and switch-off times are found in a further step. The actual power and/or thermostat time is measured, stored and compared on interrogation with a later measured power value and/or thermostat time. The change is documented. The interrogation occurs automatically after a given time and if a threshold for the documented change is exceeded, an alarm is raised.

The conical section of the inner disc can extend over the inner part of the ring-shaped disc or over the whole of its radial width.
Patent DE-19534616-A1 (DE)
IPC: B60C23/04
Filed: 1995-09-18
Abstract: The arrangement includes a signal generation arrangement on each wheel which detects the air pressure in the tyre and if necessary the tyre temperature and which provides corresponding electric pressure and/or temperature signals. A reception antenna (A, B, C,. .. N) is provided at each wheel and fastened stationary to the vehicle, adjacent to the respective wheel. A transmitting arrangement at each wheel produces a radio message which contains signals corresponding to the pressure and/or temperature signals, and transmits it to the receiving antennae. A central evaluation arrangement at the vehicle evaluates the radio message and provides a driver with information about the condition of the different tyres. Only one receiver is provided for all reception antennae, which is connected on one hand with the evaluation arrangement and on the other hand with the antennae over individual conductors. A multiplexer circuit connects a selected antenna or simultaneously several antennae to the receiver. The receiver detects the radio message and determines its field strength. The antenna with the largest field strength is selected, and the radio message is associated to the wheel which is adjacent to the selected antenna.

Title: Control of quantity and preheat of air supply to regenerative, e.g. glass making furnace
Inventor: PIEPER HELMUT DIPL ING
IPC: C03B5/237
Filed: 1995-11-24
Abstract: Controlling quantity and preheat of combustion air supplied to side-heated, regenerative tanks for glassmaking uses  furnace including charging and refining zones. Between these, along the tank sides, are burner ports (15). Burners have regenerative, chequer-work (11) chamber (10) heat exchangers (1) with vertical flow channels. Chambers (10) on each side of the furnace connect to a common gas chamber supplying combustion air and removing furnace gases, in alternation. The combustion air supply to each port is controlled by a special system of air counterflow. In this new system, beneath the chequer-work, the main upward flow of combustion air is opposed by downwardly-directed nozzles (8). The counterflow of air from these is independently adjustable for the respective burner port, following standardisation of its nominal air demand.  Also claimed is the corresponding plant to carry out the process. Preferably the counter flows of air in each chamber (10) are produced by a matrix of nozzles (8) under group control. The counter flow rate is set to increase from the charging zone towards the refining zone. In the extraction phase, air may be admixed into the furnace off-gases, by means of the nozzles (8), for post combustion.

Title: Contactless relative velocity measuring arrangement for object on conveyor belt
Inventor: KORNEFFEL BURGHARD DR RER NAT
IPC: G01P3/36
Filed: 1996-12-04
Abstract: The arrangement includes a detector arranged over the surface of a measured item with arbitrarily patterned or structured surface, and measures the velocity between the detector and the item. A coherent beam is directed onto the surface of the item, and a spatial radiation structure, moving synchronously with the measured item, is produced through a micro-structure of the surface of the item in a hemispheric space above its surface. The spatial radiation structure is picked up by the detector which is positioned in this hemispheric space sufficiently far away from the point of impact of the coherent beam, as interference patterns, without any focusing or imaging elements between surface and detector. The displacement of the interference pattern is recorded by the detector as a function of the time, and the relative velocity is determined from it.
