Title: Jib crane with tailweight - moves to position improving stability when unloaded
Inventor: BEILFUSS EGON DIPL ING
IPC: B66C23/76
Filed: 1974-10-09
Abstract: The tailweight or an auxiliary tailweight is movable from a working position where a load is suspended from the jib into one improving the backward stability when there is no load on the jib. Movement of the tailweight can be effected by an adjusting mechanism controlled by a load moment indicator. The latter can typically react to the distortion in components of the crane (8, 10, 21, 24, 27) when a load is lifted. This distortion can itself be used as the source of impulses used to control the drive to the motor for a carriage running horizontally along a lower arm.

Title: Continuous sludge filter - with trays on endless conveyor covered by supported filter cloth running over central suction channel
Inventor: OOTANI TOSHIHIRO
IPC: B01D33/00
Filed: 1975-03-04
Abstract: A suction filter for dewatering of sludge includes an endless conveyor with linked trays, open at the top and with a central hole in the bottom. The conveyor trays have raised side walls and on top a perforated plate which carries a filter-cloth with 0.25-0.3 mm mesh size. The central holes slide over a U-shaped channel which is connected to a suction plant. The sludge is applied through a nozzle at one end, passes through dewatering rollers, and the filter cake is lifted to a roller table at the other end. This prevents deformations of the filter cloth which requires frequent rectification. There is no risk of the filter cloth being damaged and the plant functions reliably. It is very suitable for insertion into a continuous process flow line such as for viscose intermediate prods.

Title: Group delay monitor for four terminal networks - displays frequency shift of modulated input signal against time axis
Inventor: SCHLOSSER KARL
IPC: H04B3/462
Filed: 1975-12-08
Abstract: The measuring circuit for determining the group delay of four-terminal networks consists of a swept-frequency generator (1) connected to one leg of the network (A) and to one input of a mixer (2). The generator is driven by a linear time function such as a saw-tooth voltage (3). The return leg of the network under test (K)(E) is connected to the second input of the mixer. The mixer output passes through a low-pass filter (4) where the difference frequency is selected (fD) and passed to a limiter (5). The square wave pulses from the limiter drive a monostable circuit (7). The monostable output pulses (11) pass through a low-pass filter (15) whose DC output amplitude (Ut) is proportional to the frequency difference. This signal is used to drive one side of a twin-coordinate indicator such as an oscilloscope or X-Y plotter. The other coordinate is driven from the sweep voltage (Uw).

Filed: 1976-03-17
Abstract: The fluidised-bed dryer has vessel parts (6, 7) which are arranged one above the other and are releasibly held together by vertical pressure which is generated by means of a hydraulic lifting mechanism. At the point of connection, the vessel parts (6, 7) have metal rings (21, 22) with radial annular surfaces (21a, 22a) resting one on the other. An elastomeric, annular seal (23) is arranged inside those portions of the annular surfaces (21a, 22a) resting one on the other. This seal is cylindrical in the non-deformed state and is rectangular in vertical cross-section.
