Title: Processing of material by fluidisation - using fluidised bed equipped with stirrer
Inventor: MAJER JAROSLAV PROF DR
IPC: C05G5/12
Filed: 1979-06-18
Abstract: Processing of solid, dissolved, dispersed or semi-solid materials with gases and/or liqs. is carried out in an expanded (esp. fluidised) bed, witb the improvement that the particles of the material are set in motion not only by the gaseous and/or liq. expansion (fluidising) medium but also by stirring. The process is useful in the mfr. of pharmaceuticals, foodstuffs, fertilisers, cement, plastics, etc., and is esp. applicable to materials which are normally difficult to fluidise (as in the case of chloramphenicol dehydration). Auxiliary stirring provides greater flexibility w.r.t. materials, fluidising media and process conditions.

Title: Liquid level monitoring system - indicates unacceptable level changes by measuring level at periodic intervals and using resulting pulses to operate triggers
Inventor: NICOLAI WALTER
IPC: G01M3/32
Filed: 1979-07-18
Abstract: The monitoring system, either analogue or digital, automatically measures liquid level as a function of time by making measurements at periodic intervals. Any changes in the level (up or down) that exceed an expected value are regarded as cause for alarm. A memory (8) stores signals describing the measured liquid level and its contents are read out at intervals as dc signals. The dc signals are converted into pulses whose leading edges are passed to a first trigger and whose trailing edges are passed separately to a second trigger. The triggers control optical or acoustic alarms when the level changes by an unacceptable amount.

Title: Air conditioning system for public hall - collects cooler dirty air from low level and lighter air from upper level for recirculation
Inventor: KANNE LUDWIG
IPC: F24F8/108
Filed: 1980-05-16
Abstract: The air conditioning system for a public room or hall uses a filtering and air circulating assembly above a false ceiling. Collector ducts extending from the floor level to the chamber housing the equipment, collect used and dirty air from floor level. Clean air is then returned from this chamber through upper side discharge ducts. Warmer lighter air with a high carbon dioxide content is extracted through grids at ceiling level and collected in a space between the ceiling and the chamber at the top. An alternative design does not include this intermediate space, but uses collector ducts at the same level. A further system uses a separate collector chamber underneath the floor, connected by the vertical ducts to the chamber at the top. These systems require little additional fresh air from outside.

Patent DE-3026660-A1 (DE)
Inventor: DOERING ERICH
IPC: E05F11/54
Filed: 1980-07-14
Abstract: A garage door with a lifting linkage, which has lateral lever arms (3), to the force arm (5) of which are connected tension springs which are fastened to the frame of the door and which are relaxed during the opening of the door and can keep the door wing in the approximately horizontal opening position, incurs the risk that, if the tension springs break, the door can slam shut and spring parts fly away laterally and thereby cause personal and material damage. To prevent this, there is provided on the side of each tension spring facing away from the door wing, and approximately parallel to the said tension spring, a protective cover (10) articulated in the region of the fastening point of the latter. The protective cover is drawn towards the door frame by means of a clamping spring, is supported on the tension spring (10) at a distance from the latter via a sliding part and has, at the free end, a locking component (17) which comes into engagement with a locking counter-component (18) on the force arm (5) of the lever arm (3) when the support of the protective cover (10) on the tension spring is cancelled. If a tension spring breaks, the catch device is drawn abruptly in the direction of the frame by the upper clamping spring, since the broken tension spring cannot oppose any resistance to the sliding part of the catching arm. <IMAGE>
