Title: Protected facility for amending stored data at exchange - requires code number and call made from authorised number before use
Inventor: BARTHOLOMAE HENRIK ING GRAD
IPC: H04Q3/62
Filed: 1979-09-27
Abstract: Customer data stored by the central controller of a telephone exchange can be amended by dialling the exchange, dialling a code number, and then entering the new data by further dialling. Since this facility is liable to misuse if the code number becomes known, it use is limited to calls from authorised numbers, e.g. in central administration. The procedure is that the caller rings the exchange, gives the code number and then hangs up. The exchange central controller checks the code number, reads out the associated stored telephone number, finds a line and causes that number to be dialled. When the caller answers, he can then enter the amendment. The facility is protected by the fact that the central controller only accepts amendments on calls it has originated. The function of the code number is merely to initiate the procedure.

Patent DE-3102330-A1 (DE)
Title: Measuring instrument for quantitative measurement of a reactive gas, especially ozone
IPC: G01N27/16
Filed: 1981-01-24
Abstract: During the reaction of a reactive gas on a catalyst, heat is produced or heat is consumed. A heat measurement provides information concerning the amount of reactive gas present. This measurement is as instantaneous as possible if the temperature sensor has a low thermal mass. This, however, makes it more susceptible to environmental influences, and its output becomes smaller. It is proposed according to the invention to arrange in a measuring chamber two thermally separated temperature sensors having as similar a design as possible. Only one of these two temperature sensors carries a catalyst and thus serves as the measuring sensor, while the other temperature sensor acts as a reference sensor.

Patent DE-3115418-A1 (DE)
Inventor: DETTELBACH ALFRED
IPC: B27G11/00
Filed: 1981-04-16
Abstract: The applicator for applying adhesive to a work piece, for example in an edge glueing machine for work pieces moving continuously through the machine, has adhesive discharge holes (6). The adhesive is supplied through these holes (6) under pressure to the edge of work pieces. Any contaminating particles, which may be present in the adhesive prior to its application to the work piece, tend to travel upwardly with the adhesive in the adhesive supply conduit (2, 4), due to their lower specific weight, whereby the contaminations may clog the discharge holes (6) and prevent the proper application of adhesive to a work piece. For avoiding such clogging the nozzle body (1) is provided with a scavenging duct (5) which is connectable to the adhesive supply conduit (2, 4) for repeatedly passing a portion of adhesive out of the supply conduit (4), whereby the application of adhesive may be performed without any trouble. The discharge holes (6) are closed during the scavenging of a small portion of adhesive. Preferably the scavenging duct portion (5') is connected to the supply conduit at a location above the adhesive discharge holes (6).

Title: Printing unit for a typewriter or similar office machine having a daisywheel
Inventor: CHVATLINSKY KURT
IPC: B41J25/24
Filed: 1981-12-21
Abstract: The frequent changeover to foreign languages with other characters or other types of lettering requires easy exchangeability of the daisywheel (1) in printing units in typewriters or similar office machines. In known printing units, the daisywheel (1) is fitted onto the free end of a drive shaft (31), it being possible for the daisywheel (1) to be coupled to the wheel receiving device (2) via a carrier pin (22). In this case, it is necessary for the carrier pin (22) and an engagement opening (26) corresponding thereto to lie in precise alignment. This exchange of the daisywheel (1) is to be simplified by the invention. For this purpose, the carrier pin (22) can be displaced in the wheel receiving device (2) into the range of action of a switch (12) in such a way that the rotary search movement between the daisywheel (1) and the wheel receiving device (2) is only completed when the carrier pin (22) has engaged securely in the engagement opening (26) of the daisywheel (1). After this automatic engagement, the switch (12) transmits a switch-off pulse to the drive motor (29) for the wheel receiving device (2). The exchange of the daisywheel (1) is thus very simple. <IMAGE>

Title: Method for fault diagnosis of motor vehicles and device to carry out the method
Inventor: GOERRES BRUNO DIPL ING
IPC: G01H3/00
Filed: 1982-01-22
Abstract: For the purposes of reliable acoustic fault diagnosis of a motor vehicle, the latter's operating noises are compared with reference noises which are generated through reproduction of fault-specific noise patterns stored on a suitable sound medium. These noise patterns are recorded in a head-based stereophonic recording method and are evaluated in a direct listening comparison with the operating noises of the vehicle under investigation using stereo headphones. The recording device and the reproduction device are adapted to one another in such a way that their overall transmission response is linear. For this purpose, the recording device, which enables recordings of sound studio quality, is fitted with an equaliser whose frequency response is complementary to that of the reproduction device. The reproduction device is designed as a compact unit which can be connected to the electrical power supply on board the vehicle and can be transported in the vehicle, thus enabling fault diagnosis even when the vehicle is in motion.
