Patent DE-3808945-A1 (DE)
Inventor: MAYER UWE DIPL PHYS
IPC: H04N9/16
Filed: 1988-03-17
Abstract: A colour flat display system comprises a colour flat display device and a driving device for driving said flat display device. The driving device comprises three analog shift registers for storing analog picture signals for three respective primary colours. Analog signals from said shift registers are read out in a line-at-a-time-method. The advantage of using an analog storing means (13, 14, 15) instead of a digital storing means is, that only one D/A-converting means (21) is necessary and that the signals can be read out very easily in paralell manner. In a special driving method always only each third of segment electrodes is supplied with the picture signal. A blocking potential is supplied to the other segments in between the active segments receiving the colour signals.

Patent DE-3817420-A1 (DE)
Title: Heading-face protection
IPC: E21D19/04
Filed: 1988-05-21
Abstract: Heading-face protection provided for the driving of roadways in underground mining can be effectively used while dispensing with bulky and difficult-to-handle netting and protective grids, because only two girder-shaped supporting beams are used for this which are connected at the front to the stage platform, specifically in a rotatable manner. These supporting beams are pivotable about a swivel joint arranged at right angles to their longitudinal axis and parallel to their transverse axis, as a result of which two-point contact with the rock is ensured in each case. Thus the supporting beams can in each case be put into a position which accurately secures and supports the parts of the heading face which tend to collapse into the roadway. This configuration of the heading-face protection, which is easy to work with and handle, ensures that it can also be effectively used underground. <IMAGE>

Title: Built-in steam heater for work kettle used in beer prodn. - has system for closing heat-exchange tubes so that they can be filled with cleaning fluid to intensify cleaning effect
Inventor: LENZ BERNHARD
IPC: C12C13/02
Filed: 1989-05-05
Abstract: The customary built-in heating element consists of a number of vertical tubes surrounded by a steam space and through which the wort circulates by natural convection.  It is proposed that the lower ends of these tubes should be provided with a manual or motorised closing device, so that a cleaning fluid can be held in the tubes for a required length of time. The device may take the form of a plate which can be moved vertically by a central rod and hydraulic cylinder, and may be guided by the heating-element supports. In its open position this plate may act as a vortex breaker for the wort leaving the kettle.  Alternatively, the device may take the form two plates which can be rotated relative to each other about a central vertical axis. USE/ADVANTAGE - This device is used in brewery applications, where wort is concentrated by boiling, and is used in conjunction with a built-in steam heater in the wort kettle.  The vertical wort passages in the heater require frequent cleaning, and the customary spray cleaning procedure involves lengthy shut-downs of the equipment. The proposed device allows the cleaning fluid to be held in the tubes and thereby increases the intensity of its cleaning effect and reduces the required down-time.
