Title: Improvements in and relating to single crystal ferrimagnetic films
IPC: C30B29/28
Filed: 1970-08-06
Abstract: 1,268,029. Coated products. INTERNATIONAL BUSINESS MACHINES CORP. 6 Aug., 1970 [29 Sept., 1969], No. 37908/70. Heading B2E. [Also in Divisions C7 and H1] A single crystal ferromagnetic film is made by depositing on a R 3 Al 5 O 12  garnet substrate (R is Y or a rare-earth metal of atomic number 58-71 inclusive) having a [111] or [100] orientation, a film of bd 3-x  M x  Fe 12  O 12  (M is Tb or Dy) and crystallising the deposited film. When the substrate orientation is [111], X is 0.1 to 0.6 when M is Tb, and 0.1 to 1.7 when M is Dy. When the substrate orientation is [100], X is 1 to 2.7 when M is Tb and 0.27 to 1.7 when M is Dy. The film may be made by sputtering, using the composition to be deposited as the cathode of the sputtering system. A two-cathode technique may be used. Alternatively, the film may be made by "spinning". In this embodiment, a concentrated solution of metal salts, e.g. nitrates, is diluted with ethanol and dripped onto a horizontally rotating substrate. The nitrate film, which is dry after 15-20 secs. spinning, is heated at 300-500C to decompose it to a glassy oxide film about 1000 thick. After repeating the process to obtain a film of desired thickness, e.g. 1Á  0.2Á, the oxide film is heated at 650-800C to cause crystallisation to a garnet structure. The product has a square hysteresis loop and a compensation temperature above 250F.

Abstract: 1,254,623. Solid state oscillators. NIPPON ELECTRIC CO. Ltd. 30 July, 1969 [30 July, 1968], No. 38295/69. Heading H3T. [Also in Division H1] An oscillator has a solid state element 5 in a main cavity 16 and a resonant frequency adjusting member 23 in an auxiliary cavity 18, the main and auxiliary cavities are coupled electromagnetically by elongated aperture 20 in a coupling member 17, the narrower dimension of the aperture 20 is not greater than the corresponding dimension of the end of the main cavity adjacent the coupling member and at least one metal piece 21 is mounted so as to protrude from a wall of the aperture into the aperture 20. The element 5 which may be a bulk effect device such as a Gunn or a IMPATT diode is hermetically sealed in the main cavity 16 by a mica plate 4, epoxy resin 8 and an 0-ring 11 and the cavity 16 may be filled with an inert gas such as argon. The shape of a U piece of metal 21 within the aperture 20 may be changed to adjust the load on the element 5 and compensate for the characteristic of the element 5. The capacitive coupling member 17 with its aperture 20 separate undesirable oscillation modes from the desired mode. Metal foils 36, 37 improve the contact between the block 1 and member 17. A groove 33 is filled with resistive material 34 which suppresses undesired oscillations. A return line of a quarter wavelength within a hole 24 forms a H.F. choke 25. The bias for the element 5 is supplied via a H.F. choke 9 having a PTFE coating 10 and the block 1 and a stud 6 may be of copper. The output is taken from a window 19 and may be increased by adjusting the shape of the metal piece 21 or the length of screw 35. Also the output may be taken through a coaxial cable. In a modification (Fig. 5, not shown), the piece 21 is replaced by an adjustable screw (38).

Title: Patterned sheet material
IPC: B44F9/04
Filed: 1971-08-09
Abstract: 1365066 Coloured porous plastics materials PORVAIR Ltd 9 Aug 1971 [10 Aug 1970] 38520/70 Heading C3C A polymer sheet material of which at least one surface has a colour variation integral with the said surface the colour variation being localized at or adjacent the said surface, consists of an integral porous sheet of particles bonded to each other exhibiting a pore size 10-150 microns as determined by the method of British Standard Specification 1,081,612. The term "coloured" indicates translucent, transparent, black and white. The polymer sheet may be 0À5-10 mm. thick and the colour variation extend inwards from the surface not more than 30% of the thickness of the sheet. The sheet material may be produced in a number of ways. In one embodiment particles of at least two differently coloured bondable polymer compositions are disposed as a layer on or close to the surface of a support the particles being disposed as a thin layer on the support and having diameters of less than 300 microns so as to provide colour variations on the face of the said layer adjacent the support and in which the particles are treated so as to bond them in to an integral self supporting porous sheet, the support being one from which the porous sheet can be removed without damage. The particles are preferably thermoplastic and the bonding may be achieved by sintering. Several modifications of this preferred embodiment are discussed. In one embodiment the different coloured polymer particles may be applied simultaneously or sequentially as thin layers in separate areas and then further different coloured polymer particles are applied at a greater thickness than the desired final thickness and then spread to the desired trial thickness, e.g. by being passed under a die or by a bar passed over the support at the desired spacing of mixing occurring between the various layers. This produces a degree of partial blending of the colours. Suitable supports are glass plates. Example 1 describes a porous product obtained using polyethylene powder and prepared by applying black-pigmented powder, then violet powder and then unpigmented powder. Example 2 repeats Example 1 using a polyvinyl chloride powder. In the examples the final assembly of layers is levelled off with a spreader bar thus causing some slippage of the layers giving rise after sintering to a mottled or marbled appearance.
