Patent DE-19640404-A1 (DE)
Inventor: KRAENERT JUERGEN DR
IPC: H04N5/74
Filed: 1996-09-30
Abstract: The invention relates to a device to display images on a projection screen (2). Said device has a laser (4, 42, 44, 46) emitting a laser beam (5), a deflecting device (8, 9; 47) to deviate the laser beam (5) and an image-producing device (1), which is connected to a control device (48) to control the laser and the deflecting device (8, 9; 47). The image-producing device (1) can be operated in two modes. The first mode is used for normal projection while the second is an operational mode, in which the laser beam is harmless for a person (16) that finds his or herself in the area giving access (14) to the laser (4; 42, 44, 46). The device also comprises a safety circuit having at least one sensor (22, 24, 26; 60; 72, 74, 76, 78; 84; 90), which is placed between the image-producing device (1) and the projection screen (2) to detect the presence of objects within a surveillance area (17) larger than that giving access to the laser (14). The safety circuit changes the image-producing device (1) to the second operational mode when the presence of an object is detected.

Title: Indicating system indicating dust amount in vacuum cleaner dust container
Inventor: SUK-GU KIM
IPC: A47L9/19
Filed: 1996-10-30
Abstract: The system (200) includes a transparent first cylinder (210), which has a first adjusting cap unit (212), which is inserted at one end, for adjusting the operating time of the indicating system. A flow section of a first air flow at atmospheric pressure is controlled. An indicating medium is elastically carried by a first carrying medium. The indicating medium primarily lowers the vacuum in the dust collection chamber, and indicates continuously the amount of dust contained in the dust container. A second cylinder (310) is provided, which has a second adjusting cap unit (312) inserted in one end of the cylinder, to adjust the operating time of the indicating system. The flow section of a second air flow at atmospheric pressure is controlled. A pressure control medium is provided for the secondary lowering of the vacuum in the dust collection container and a second carrying medium flexibly carries the pressure control medium. A connecting line produces a conducting connection between the two cylinders, also a pneumatic connection of the two cylinders to the dust collection chamber.

Abstract: Hitherto, glazing defects have arisen during glazing of ceramic substrates with an electrostatically applicable coating powder. This problem is solved by the inventive coating powder CPAB and the coating method. The electrostatically applicable coating powder CPAB contains 1 to 50 wt. % of a glass-forming composition A which begins softening at 400 to 750  DEG C and 99 to 50 wt. % of a glass-forming composition B which begins to soften above 750-1,100  DEG C. Preferably, the coating powder consists of 2.5 to 25 wt. % A, 75 to 97.5 wt. % B and 0 to 20 wt. %, specially 2 to 10 wt. % of thermally or chemically activatable adhesive agents. The coating powder CPAB is electrostatically applied as a single powder. Alternately, coating can be applied in two layers, wherein the CPU powder contains at least 5 wt. % of glass-forming composition A as a lower layer and the powder CPO contains at least 50 wt. % of glass-forming composition B as an upper layer.

Title: Active alarm list handling in subordinate management level
Inventor: HIRSCH LUCIAN
IPC: H04M3/10
Filed: 1997-09-16
Abstract: The method involves rearranging a list of active alarms in a subordinate management level of a communications network by storing the alarms appearing in this level, in the sequence of their appearance, and through transmitting the stored alarms to a next higher management level, after a disturbed communication is reinstalled between the subordinate and the next higher management level, to enable the rearrangement of the list of active alarms of the subordinate management level in the next higher management level. The appearing alarms are respectively stored, dependent on the meaning (Critical, Major, Minor, Warning) of the individual alarm on the function of the affected object in memories (QueueCr, QueueMa, QueueMi, QueueWa) of different priority. An appearing alarm of higher meaning (Major), is stored in the memory with the lowest priority (Queuewa), if the memory (QueueMa) associated with the priority of the meaning (Major) of this alarm is full.

Title: Control of energy flow of hybrid electric car
Inventor: BUDIG PETER-KLAUS PROF DR SC T
IPC: B60L50/15
Filed: 1997-10-11
Abstract: The control system regulates the energy flow in a hybrid electric car. The internal combustion engine (1) is regulated by a speed controller to run at constant speed independently of its load. Consequently its control system is decoupled from the remaining components of the drive system.  The internal combustion engine (1) drives a synchronous generator (2). The 3-phase AC produced is fed to a rectifier (3) via a switch (6). A capacitor and an accumulator battery (5) are connected across the output from the rectifier. The rectifier and battery DC output are connected to an inverter (4) which supplies variable frequency 3-phase AC to a motor-generator (M/G) driving the front or rear wheels of the car. The accelerator pedal is connected to the inverter to control the frequency. The brake pedal may also be connected to the inverter to control regenerative braking.

Title: Turning tool with seating piece e.g. hexagonal wrench for fasteners
Inventor: VASUDEVA KAILASH C
IPC: B25B23/10
Filed: 1997-10-28
Abstract: The tool (1) has an end (3) which has an annular recess (2) near the end and fits into a recess in the fastener head. The tool has a reduced cross section which is not symmetrical with the tool axes at the annular recess. A spring steel locking piece (6) fits around the reduced section into the annular recess. When the tool is operated and slipping takes place, because of its non-symmetrical support and zero applied torsional moment the locking piece expands or skews in response to relative movement of the tool head and the locking piece and keeps the tool head from slipping out of its correct seating.

Inventor: SCHUELER ROLF
IPC: B60N2/07
Filed: 1998-02-05
Abstract: The seat part of a motor vehicle seat is fixed on sliding rails and each sliding rail can be displaced longitudinally in a guide rail (10) fastened to the vehicle floor. At least one sliding rail can be fixed on the guide rail (10) in a variety of longitudinal positions by means of a locking device, whereby a stop element is provided for between the sliding rail and the guide rail (10). To provide an energy-absorbing elastic stop element and at the same time avoid production steps for the retaining element which holds the stop element, said stop element is embodied by an impact absorbing body which with a snap-in head (15) reaches through a through-hole in the guide rail (10) and by a locking hook which reaches through said impact absorbing body and latches into the guide rail.
Patent DE-19808371-A1 (DE)
Inventor: DILLINGER MARKUS
IPC: H04B7/26
Filed: 1998-02-27
Abstract: According to the inventive method for transmitting information between a base station and other stations in a radiocommunications system, a common frequency channel is used in the down- and uplink directions. At least one switching time is fixed between the down- and uplink directions. These bursts can be configured for maximum spectral efficiency in accordance with mobile radiotelephony requirements. However, a burst of reduced duration is transmitted before and/or after the switching time. In TDD transmission systems, this therefore prevents the receiving and sending operations from overlapping for the switching time as a result of disadvantageous relative signal propagation times.
