Title: Sensitizers for the photolysis of organic halogen compounds
IPC: C09B23/01
Filed: 1970-09-11
Abstract: 1318408 Photo-sensitive materials MINNESOTA MINING & MFG CO 11 Sept 1970 [12 Sept 1969] 43619/70 Heading G2C [Also in Divisions C3 and C4]  A photo-sensitive composition comprises a photolysable organic halogen, a dye of formula as sensitizer wherein R 1  and R 2  are either aryl radicals or together complete a 5-or 6-membered ring, n is 1 or 2, R is aryl or heterocyclic radical and Ar is arylene; the dye being free of groups more basic than diphenylamine and being unreactive with the organic halogen in the dark under ambient conditions. The composition may also contain materials which react with the halogen free radical or acid produced on photolyses e.g. photo-polymerisable monomers, leuco dyes and tetrahydropyranyl derivatives of aromatic hydroxy and amino compounds. The sensitizers extend the sensitivity of the composition into the visible wavelength. In the examples the composition was admixed (1) with 1-(2-tetrahydropyranyloxy)- 4-methoxy naphthalene and a binder, in agewise exposed, contacted with a sheet containing silver behenate and heated to give a black image, (ii) with an acrylic monomer and a binder, coated on a support, laminated to a polyester over sheet, imagewise exposed, cover sheet removed and developed with toner powder to give a positive image (iii) with a binder and leuco methylene blue, imagewise exposed to give a green negative  image which is fixed by heating. The composition may also be based in other processes e.g. those of Specification 1261938.

Abstract: 1373096 Laminates BRITISH STEEL CORP 22 Sept 1971 [22 Sept 1970] 45154/70 Heading B5N [Also in Division B2] Ferromagnetic material for use in a magnetic circuit comprises ferromagnetic sheet material having bonded to it a layer of material effective to restrain magnetostrictive movement of the sheet or of components produced from the sheet when excited by an applied magnetic field. The bonded layer reduces the noise level in magnetic cores made of the ferromagnetic material. The material of the bonded layer may be a natural or synthetic polymer resin or an electrically insulating glass. The bonded layer is generally itself electrically insulating but the ferromagnetic sheet may also have a layer of oxide insulation. Moreover, two or more isotropic or anisotropic ferromagnetic sheets may be bonded together by intermediate layers of the above material to restrain magnetostrictive movement and to further restrain the generation of noise, the bonding layer may have a filler of mica flour, mica platelets, ferric or ferrous oxide or a ferrite material in finely divided form. When isotropic sheet is used, the sheet may be subjected to mechanical strain while the bonded or bonding layer is hardened, the layer then maintaining the strain when hardened so as to give the isotropic sheet magnetic properties similar to those of anisotropic sheet. The bonding layer may be applied to the sheet or sheets in particulate or viscous form or in the form of an extruded solid sheet.
