Title: Stabilisation of two bubble types in crystal lattice bubble memory - using magnetic film with easy axis at angle to crystal substrate axis
IPC: H01F10/24
Filed: 1976-10-22
Abstract: Different types of bubbles are produced by implantation of ions in a magnetic bubble film placed or deposited on a nonmagnetic substrate. An artificial crystal is formed on an oriented nonmagnetic crystalline seed, so that the crystal produced has a 111 longitudinal axis and a (111) plane normal to this. The crystal, with oriented axis, is cut at an angle of 90 degrees to the 111 axis and then a substrate is produced with its vertical axis inclined at a small angle to the 111 axis. The magnetic bubble film is produced on this substrate, so that a film with a number of bubble types is produced, with its magnetic main axis (easy axis) at an angle which is a small multiple of the small angle of inclination to the 111 axis. Ions are implanted in the surface of this film in order to stabilise 2 different types of bubbles. Two stable types of bubbles are produced, instead of only one type. The crystal consists of a Gd-Ga garnet and the film of Gd-Ga garnet with S=1 and S=0 or S=1/2 bubbles or Y2.38La0.09Eu0.53Fe3.9Ga1.1O12 with S=0 and S=1 stabilised bubbles. The cut is made at 1 1/2-10 degrees, esp. 4 degrees to the axis, so that the easy axis is at >6 degrees, esp. 22 degrees and a considerable component of the easy axis is in the plane of the film.

Title: Treatment of water based fluids with an adsorbent powder - with chemical flocculation of the adsorbent and controlled agitation in the adsorption column to prevent channelling
IPC: C02F9/00
Filed: 1977-03-28
Abstract: An adsorption process is described in which water based liquids are contacted with a flocculated adsorbent powder. The liquid rises through the treatment zone, the lowr part of which is equipped with an agitator. The speed of rotation, frequency and duration of the agitation can be varied. To ensure that adequate and stable flocculation takes place, a chemical flocculant is pref. added to the fluid in the lower treating zone. The max. concn. of flocculant in the fluid is 0.05 mg/l. To minimise the vertical movement of the flocculated grains, the vertical treating zone is pref. divided into smaller zones by horizontal filter plates. The process is partic. suitable with the use of activated carbon powder. The carbon can either by periodically regenerated or continuously removed from teh bottom of the treating column whilst fresh carbon is fed into the top of the column. Process is esp. useful for the removal of organic impurities from water.
