Patent DE-2350967-A1 (DE)
Title: Cleaning envelope type gas filters - with travelling back flush nozzle providing pulsed air on one pass and direct air on return
Inventor: MARGRAF ADOLF DIPL ING
IPC: B01D46/00
Filed: 1973-10-11
Abstract: Envelope type air filter has self cleaning action incorporating a moving nozzle which travels over the outlet faces of the filter bags and provides a back flush of clean gas to remove dust deposits from the cloth. As the traveller moves in one direction, the clean air is pulsed by rotation of a vane over the mouth of a nozzle. while on reverse direction the rotation is removed, and a counterbalance ensures that the nozzle is not blocked. This gives a direct impulsed gas purge to the bags. Used for all gas cleaning operations. The pulsing action imparts a shaking action to the bags and encourages the cake of dust to slide off the bag surface. The direct purge on the reverse movements tends to push out dust particles embeded in the bag fabric and thus complete the cleaning action. The distribution means allows for a relatively small back flush fan.
Patent DE-2359248-A1 (DE)
Title: Fusion reactor with whole number of helical windings - in which plasma is stabilised by means of a single phase transformer
IPC: H05H1/12
Filed: 1973-11-28
Abstract: A torus-shaped fusion reactor has the field generation coil mounted exclusively on the outer wall of the vessel. The winding is constituted of a number of helically wound layers each comprising a whole number of turns; this generates the enclosing field. A single-phase transformer is used for stabilising the plasma in the field and for heating it. The transformer is supplied with alternating voltage with a steep zero passge flank, such as sinusoidal H.T. voltage or a L.T. square wave voltage. A number of layers of winding each comprising a whole number of helical terms may esp. be used for generating a constant magnetic pressure; these generate a non-whole number of turns of the field; the number of turns of the winding are decreased from layer to layer by >=1, to obtain a field with an outwardly-increasing twist of the force lines to promote stability. Effective stability of the plasma within the field is thus achieved.

Title: Precision differential pressure gauge - esp for aircraft fuel storage, has two-stage spring giving high accuracy at low pressure
Inventor: RUNGE HANS-JUERGEN
IPC: G01L13/02
Filed: 1974-02-07
Abstract: A precision differential pressure gauge, for pressure and flow measurements of all types esp. for filter plants, water separators (for aircraft fuel) and/or pressure resistance measurements, comprises a glass piston suspended in a glass cylinder by a "duo" tension spring constituted of a weak and a strong spring in series with an abutment to limit the travel of the weak spring. The glasses of the piston and cylinder possess the same coefficient of thermal expansion. The graduation marks of the scale are 25 mm long and 0.5 mm wide to give no-parallelex reading along an imaginary line to the axis of the piston. The whole unit can be pivoted upside down, to permit removal of air from the bottom chamber. Each element of the filtration and water separation plant is connected through a pipe to a coordinator and the precision pressure gauge. Readings to plus-or-minus 0.05% of the differential pressure at 20 degrees C are obtained. The weak spring provides the high accuracy in the low-pressure range.

Title: Improved sail for dinghy - with horizontal plates along boom to separate high and low pressure areas
IPC: B63H9/06
Filed: 1974-10-08
Abstract: The boom (18) of the main sail of the dinghy is fitted with horizontal flanges (22) on either side to limit any airflow down the sail and over the edge of the boom. When tacking into the wind the drive on the sail is generated by the aerodynamic pressure differences between the front and rear of the sail, and the flanges enhance this pressure difference right down to the boom level for improved drive. The flanges can be constructed to fold down if running before the wind, to minimise any injury risk. They can also be held in their operating position by sprung hinges for safety.
