Title: Cleaning hot gas filters by water injection - causing pressure wave on clean gas side to release filter cake
Inventor: DAVID ALFRED DIPL ING DR ING
IPC: B01D46/04
Filed: 1975-09-09
Abstract: Process involves creating a pressure surge on the clean gas side. This is done by releasing a charge into the clean gas space which causes a sudden and considerable increase in volume. The pressure pulse thereby created acts on the clean side of the filter medium and causes the cake to drop off. A suitable charge is a small volume of liquid which will flash off under the conditions in the filter. It is heated to its b.pt. and released under pressure. Water is esp. suitable for hot gases over 100 degrees C. Other suitable materials are propellents, gum powder, self igniting materials, detonators etc. Conventional techniques having compressed air are unsuitable because they tend to cause thermal shock on the filter. The system described avoids this. It does not require large vols. of air to be heated up and needs no additional complicated equipment.

Title: Blown plastic automobile fuel tank with stilling chamber - formed by blow moulding main tank onto preformed chamber
Inventor: RAEDLER HELMUT
IPC: B29C49/48
Filed: 1975-09-19
Abstract: Mfr. of a blown plastics article, comprising two compartments sepd. by a partition, comprises placing a preformed object (to constitute one compartment) in a recess in one inner face of the blow mould, then blowing the main blow moulding in the mould (to form the outer compartment). During the blow moulding stage, the preformed object is subjected to an internal pressure which counter-balances the blow moulding pressure. Pref. a pressurised line connecting the two compartments together ensures the same pressure in both. Alternatively, a pressure line leads only into the main blow moulding, but the preformed moulding is fitted with a projecting hollow needle, which pierces the blow moulding as the latter fills the mould, and thus forms a communicating duct between the two compartments.

Title: Meal compacting equipment for sack packing - uses auger rotating in porous sintered pipe subjected to external vacuum
IPC: B65B39/04
Filed: 1975-12-09
Abstract: The equipment aerates then compacts powdery and fine granular materials, e.g. meal, which is then packed in sacks of paper or plastic. It incorporates a sintered metal pipe whose porosity is selected to give the desired degree of permeability, and which can be of any desired length. The metal pipe is subjected to a vacuum from an exhauster PIPE, so as to draw the air out of the material. The powder is blown free by compressed air delivered via the exhauster pipe. The material is forced into the sack by a helical auger rotating in a round tube. The auger pitch becomes finer at the sintered pipe, tending to compact the aerated material and press it against the pipe by centrifugal force.

Title: Controlling carbonisation time in coke ovens - by regulating the length of the regenerator half cycle times
Inventor: PRIES ERICH DIPL ING
IPC: C10B21/20
Filed: 1975-12-11
Abstract: In a coke oven battery the heating walls are subdivided into rows of heating flues alternating with oven chambers, the contents of which are heated uniformly in respect of height by controlling the combustion in the flues. Using baffles, bricks, sliders etc. which act on the various heating flues of each heating wall. The amt. of heating gas supplied in unit time is adjusted to provide a carbonisation time corresp. to a high prodn rate for the battery. The method of application of the flames in the heating flues as well as the position of the various control element as maintained above are kep unaltered when the carbonisation time is increased, but the lesser heat requirements are taken into account by introducing an interruption into each half cycle of regeneration. System provides a much simpler and more rapid method of altering the carbonisation time while maintaining complete uniformity of heating throughout the oven chamber, than the usual method of altering the rate of feed of heating gas and the position of the control elements for air, combustion gases etc, which can take several weeks.
