Title: Cleaner for filter elements screening dusty exhaust gases - has mobile reverse flow feeders blowing cleaning pulses intermittently
Inventor: SINGER HANS DIPL ING
IPC: B01D46/00
Filed: 1977-02-04
Abstract: A cleaning mechanism for filter elements, esp. for filter cells arranged inside a dust-laden air chamber, is designed for use where the contaminated air flows from outside through the filter material into the cell and out through a slot into the clean air chamber. A source of compressed air is provided so that by means of a nozzle connection to at least one channel in the clean air chamber, air can be blown briefly through a slot and through the filter material from the inside to the outside. The air nozzle and the channels form a unit which can be moved stepwise. A Laval nozzle is used and this has a long slot through which the compressed air blows into a venturi constriction in the channels. The compressed air nozzle is arranged in the lower zone of the channels with the venturi, and the channels also have a constriction in the zone of the slot leading into the filter cell. This constriction is smaller than the width of the slot and the edges of the channels are flanged. The channels diminish in cross-section upwards and their pitch is such that as they move only one channel is aligned to a filter cell slot. The compressed air supply is from a vessel mounted on the conveyor between the channels, and valves feeding the corresp. nozzles are changed over alternately by servo valves. The filters are cleaned by pulses of compressed air by a device having a low investment cost and a high degree of efficiency which in no way affects the operation of the dust separators.

Title: Anodising aluminium for bonding with polymer adhesives - is carried out in phosphoric acid bath at 10-30 degrees C
Inventor: MARCEAU J
IPC: C25D11/08
Filed: 1977-02-10
Abstract: Porous aluminium oxide layers are formed by anodising the article in a bath contg. 1.5-50 wt.% (10-12) wt.% H3PO4 at 10-30 (21-24) degrees C, and using an anodising voltage of 1.50-50 (10-15) volts. Pref. the anodising process is carried out for 10-30 (20-25) mins., and the article is rinsed within 0.3-2.3 mins. after anodising is completed. The process is useful for pretreating aluminium articles which are to be bonded with polymeric adhesives such as epoxy adhesives, e.g. in aircraft manufacture. The porous aluminium oxide layer formed is compatible with polymeric adhesives and gives high bond strengths. The resulting adhesive bonds have high resistance to hydrolysis and failure of the bond is generally by cohesive failure in the glue line rather than adhesive failure in the oxide layer or at the glue/oxide interface.
