[Also in Division F4] In a self-cleaning cooking device with walls exposed to products resulting from heated foods, the walls are coated with a base enamel layer and a porous matrix layer, overlying the base enamel, having a finely divided oxidizing catalyst distributed throughout the matrix, the porous matrix comprising a particulate aggregate component defining the porous structure and a binder component bonding the aggregate component particles to each other and to the base enamel where in contact therewith, the binder component being of fritted vitreous particles. The aggregate component may also be vitreous and is then of larger particles having a softening temperature higher than that of the binder particles. Otherwise, alumina or silica particles may be used as the aggregate. An intermediate layer of vitreous particles, with or without alumina and/or colloidal silica particles, may be provided having a lower softening temperature than the base enamel. Oxidation catalysts given are rare earths, particularly cerium; catalytically active compounds of Cu, Sn, V, Nb, Bi, Cr, Mn, Co, Ni, Mo, W, Re, Fe and precious metals; the precious metals themselves such as Rh, Ru, Pd, Pt. Rare earth carbonates and metal oxides (of the above metals), cerates, manganates, manganites, chromates, chromites or vanadates can be used. The surface of the wall must be porous and, if necessary, part of the glass may be etched away to re-expose the catalyst. Additional catalyst may be added either before or after firing.

In a winch dyeing process, tubular or open width fabric is passed in folded sinuous form together with dye liquor through a restricted arcuate passageway C, the liquor outlet level being maintained lower than the liquor inlet level and the level at which the fabric is unfolded. The liquor passes through perforations c<SP>1</SP> and c<SP>2</SP> in the passageway and (by means of a pump) through ports v<SP>1</SP> and/or v<SP>2</SP> to spray means at the inlet side of the passage. The liquor may be heated by a heat exchanger before or after passing through port v<SP>1</SP>. A single spray means (on the back of carpet material) or two spray means acting alternately may effect the folding. Wide low energy sprays may be used. As shown, tubular fabric is sprayed by alternate means B<SP>1</SP> and B<SP>2</SP> and means TS above the winch W, liquor passing into an inner space a<SP>1</SP> is heated by exchanger d, and the material is ballooned and simultaneously twisted before passage over the winch by valved inflating means AP and roller peg RP.

Abstract: 1,230,776. Coating pipes. FEB (GREAT BRITAIN) Ltd. 7 June, 1968 [7 June, 1967], No. 26183/67. Heading B2E. [Also in Division F2] Protective coatings or linings are applied to the inside of hollow vessels or pipes made of concrete during or after the casting or moulding of the concrete by 1) either applying a release agent to a partially inflated core and applying a curing protective composition over the release agent or coating the release agent on to the partially inflated core with the curing resin, 2) inserting the core into the mould or into the existing pipe or hollow vessel, pouring concrete around the core if in the mould 3) fully inflating the core to a predetermined pressure, 4) allowing the concrete and/or the coating composition to cure, 5) deflating the core and withdrawing the core from the mould or the hollow vessel or pipe. The release agent may be a sleeve of polyethylene or a silicone, wax or oil. An example of a protective resin coating composition comprises 100 parts liquid epoxy resin, 60 parts aromatic amine liquid hardener, 300 parts filler and consistency control agent, e.g. fine silica flour, 20 parts colouring pigment, e.g. iron oxide. The coating composition may be applied by brush, trowel, roller or spray. The core may be of rubber, synthetic rubber or a resilient plastics material. Where a reinforced lining is required, the core coated with the resinous composition is wrapped round with glass fibre or similar reinforced materials in the form or loose fibre, matt or woven cloth and further resinous composition applied. In Figure 1 the core A having outer sleeve B of polyethylene coated with a curing resinous composition C is placed in position in a mould whilst the composition is still in the partially cured state and the concrete poured around the core. The core projects from the end of the mould into which the concrete is poured and is provided with an inflating valve a. When the concrete C' and the resinous composition C have both cured, the core A is deflated and removed together with the outer sleeve B of polyethylene leaving a smooth coated pipe bore in the concrete C'. Where a polyethylene sleeve B is not employed, the core may be treated with a release agent or the release agent may be coated with the curing resinous composition.

A transformer or inductor includes a core 10, Fig. 1, comprising a number of superposed layers 14a-14d, 16a-16d, of anisotropic magnetic material, so magnetized that a field H applied to the core by means of winding 42, Fig. 4, causes the magnetization vectors M 1  of alternate layers 14a-14d to rotate in one direction, and the magnetization vectors M 2  of the intervening layers to rotate in the opposite direction. In use the field H is an alternating field applied along the bisector of the angle between M 1  and M 2 , so that M 1  and M 2  oscillate through angles # 1 , # 2 . For a transformer there are two windings 42, 44, the field  H being established by means of the primary winding 42. For an inductor, winding 44 is omitted. In the embodiment of Fig. 4 rectangular core layers 14a-14d, 16a-16d are deposited on a glass or metal substrate 12 with intervening insulation 18. In alternative embodiments, Figs. 7, 8, not shown, the layers may be either superposed annuli, initially magnetized alternately radially outwards and inwards, or concentric cylinders alternately magnetized in opposite directions parallel to their axis. Pulse storage element, Figs. 1,5.-The element includes the core 10 of Fig. 1 so magnetized that a field H applied to the core by means of a winding 52, Fig. 5, causes the magnetization vectors M 1  of alternate layers 14a-14d to rotate in one direction, and the magnetization vectors M 2  of the intervening layers to rotate in the opposite direction. To achieve this successive layers of the core have their easy axes in different directions. The rotation of the magnetizations is detected by sense coil 54.
