Patent DE-3809807-A1 (DE)
Title: Propellent charge powder and process for producing propellent charge powder
Inventor: KNOBLOCH JUERGEN DR
IPC: F42B5/16
Filed: 1988-03-23
Abstract: For controlling the combustion behaviour of mouldings for propellent charge powder, it is known to exert an influence on the combustion conditions by varying the geometry and/or by varying the surface coating. This requires additional working steps on the one hand and, on the other hand, is limited in its effect. According to the invention, a propellent charge powder with extruded cut mouldings is provided, which is characterised in that the moulding has, over the cross-section, at least one essentially annular layer surrounding a core region of different material properties. The propellant, according to the invention, can be used for diverse applications and with the use of the most diverse, widely different material compositions. <IMAGE>

Abstract: The invention relates to a method for the specification-consistent programming of a transmitter apparatus for mass or individual communication. When the apparatus is taken into operation or its specification-consistent use is changed, it is provided that, for the purpose of apparatus identification, a videotext page is transmitted covered or uncovered to a connected program source, e.g. external computer, which indicates information on storage capacity of the program memory, internal and external interfaces and the functionality of the apparatus. Program packets prepared for the apparatus are offered and scheduled for recall by the program source, likewise via a selected videotext page. After checking the available capacity against the total capacity of the selected program packets, the latter are accepted by the program memories.

Title: Method and device for monitoring and securing large surface areas having materials stored distributed on the surface
Inventor: JAEGER GERNOT
IPC: G08B17/00
Filed: 1988-06-07
Abstract: For the detection of danger and the defence against danger on storage surfaces and in storage spaces, especially in regard to the danger of fire, there is a desire to configure an automatic monitoring system in such a way that it is simple to install, that its indication and reporting of the place of danger and the entry time of the danger are detected as accurately as possible and that its functioning is largely insensitive with respect to disturbances. According to the invention, it is proposed to install a sensor responding to characteristic physical phenomena in a fixed position and above the storage surface in such a way that the storage surface is periodically repeatedly scanned in a scanner-like method and that the local measured values are respectively coupled with a location value and a time value so that, in the event of danger, an unequivocal identification of the location of the danger and of the entry time of the danger can take place and consequent corresponding reports and/or the initiation of specific measures of defence against the danger can be carried out. <IMAGE>

Title: Device for continuously performed, separate recording and measurement of head and trunk movements during standing and locomotion
Inventor: CLAUSSEN CLAUS-FRENZ PROF DR M
IPC: G01S5/16
Filed: 1988-09-02
Abstract: The invention relates to a device for continuously performed, separate recording and measurement of head and trunk movements during standing and locomotion, which consists of a head and trunk marking which is arranged on the subject and formed from optical markers, as well as a device which is fixed at a distance from the subject and continuously receives and records the optical signals of the markers. The device is intended to be easy to operate, to have a high measurement accuracy, to permit time-critical spectral movement analysis, and to prevent superimpositions and overlaps when recording the optical signals. This is achieved according to the invention by having the device consist of at least three sensors which adopt a polygonal arrangement and whose measured values can be matched with one another in a temporal sequence and can be continuously interrogated by a central unit in the form of data series. In addition to the field of medicine, the device can also be used to monitor movements of personnel in dangerous work areas, or in conveyor technology for the purpose of exactly locating and guiding moving machines or workpieces, or for assembly. <IMAGE>

Patent DE-3907464-A1 (DE)
Title: Nozzle for a fluidised-bed firing
Inventor: MUELLER HORST
IPC: B01J8/24
Filed: 1989-03-08
Abstract: The invention relates to a low-backflow nozzle for a fluidised bed which is designed in a simple way. When the nozzle flow is interrupted, the bed material which penetrates rearwards into the widened cross-section of the nozzle constructed like a syphon is continuously compressed along the way, until eventually, with the simultaneous action of frictional forces, self-blocking occurs, and the nozzle is closed on the side of the fluidised bed. If the nozzle flow now resumes, the cross-sectional widening with increasing flow path permits a loosening of the bed material and thus removes the self-blocking. The nozzle can be blown free again in the direction of the fluidised bed. <IMAGE>

Title: Utilisation of wave power - involves pump actuated by rising and falling floats to generate electricity
Inventor: JANOWICZ MIROSLAW
IPC: F03B13/18
Filed: 1989-04-21
Abstract: The generator derives its power from the energy in sea waves.  It is driven by a turbine which is supplied with high pressure water from a pump. The pump is mounted on the seabed and the pump piston rod is attached by cables (17) to a first float (11) which floats on the sea surface.  As the waves rise this float pulls the piston upwards. Two other floats (13), which are completely submerged, are attached by cables (14) to the piston rod.  These cables pass around pulleys so that as the waves fall the second floats (13) pull the piston downwards. Water is pumped out through the pipe (3) to the turbine. USE - Utilisation of wave power.
