Abstract: 660,367. Magnetrons. PATELHOLD PATENTVERWERTUNGS- & ELEKTROHOLDING AKT.-GES. Aug. 16, 1948 [Aug. 16, 1947], No. 21565/48. Class 39 (i). A magnetron for ultra-short waves comprises concentrically enclosing the cathode_at least two annular hollow cavity resonators whose inner walls consist of interdigitating segments; the cavity resonators are mutually coupled so that the sum of the oscillatory magnetic fluxes surrounding the cathode is zero. The loss of high - frequency power through the cathode is thereby minimized. As shown, two cavity resonators 2, 3 are separated by a common wall 12. The anode segments 4 surrounding the cathode 1 are connected alternately to the common wall 12 and to the end walls 13, 14. The segments connected to the end walls are as shown connected together, or they may be separate. The leads 5, 7 of the output leads 5, 5, 7 are connected directly together. They may be connected together inside the envelope and the two leads emerging from the envelope arranged cross-wise with the cathode heating leads. Alternatively the cavity resonators may be coupled together by a wire 50, Fig. 5, passing from one resonator to the other through the common wall 12 and forming a loop in each. In an embodiment with three adjoining cavity resonators each with an output coupling loop connected to a concentric line, the resonators are coupled to oscillate with a mutual phase displacement of 120 degrees by means of capacitative couplings between the inner conductors of the concentric lines.

Abstract: 1,196,672. Reducing unsaturation in polyols. DOW CORNING CORP. 31 May, 1967 [31 May, 1966], No. 21738/67. Heading C3R. A process for reducing the amount of unsaturation in poly-(oxyalkylene) polyols comprises reacting the polyol with a siloxane containing at least two silicon bonded hydrogen atoms per molecule in the presence of a platinum catalyst. The reaction ties together the two unsaturated ends of the polyol to form a silicon - containing polyhydroxy compound. Suitable polyols include diols and triols such as poly-(oxypropylene) diols and triols having a M.Wt. of 3-4000 and poly-(oxybutylene) diols. The siloxane may be a homopolymer, copolymer, linear, branched or cyclic ; those specified are tetramethyldisiloxane, 1,1,1,3,5,7,7,7-octamethyltetrasiloxane, 1,1,1,3,5,7,9,9,9-nonamethylpentasiloxane and methyl hydrogen cyclotetrasiloxane. The siloxanes are generally added in stoichiometric amounts w.r.t. the amount of unsaturation. The platinum catalyst may be in the form of platinum black, platinized silica gel, platinized asbestos, platinized charcoal, platinized gamma alumina, complexed platinum or chloroplatinic acid, the latter being preferred. The catalyst is employed in concentrations of 1 x 10-<SP>6</SP> moles of Pt per unsaturated molecule in the polyol. Polyurethanes are prepared from the upgraded diols by the addition of the following: commercial poly - (oxypropylene) triol, ditertiarybutylphenol, P-33 carbon black, methyl tin trichloride, xylene and toluene diisocyanate.

Abstract: 1,086,607. Semi-conductor devices; resistors. NATIONAL CASH REGISTER CO. May 19, 1966 [June 3, 1965], No. 22230/66. Headings H1K and H1S. The separate components of an integrated circuit formed in a semi-conducting layer 11 on a semi-conducting substrate 10 are isolated from each other by insulating material 21 vapour deposited in channels extending completely through the layer 11. In the preferred form the layer 11 is of silicon epitaxially deposited on a monocrystalline silicon substrate 10 of opposite conductivity type. Separate devices are formed by diffusion into the layer 11, e.g. to comprise a transistor 15, 14, 11 and a resistor layer 16 of opposite conductivity type to the layer 11, and the channels are then etched using an oxide masking technique, the mask being shaped by etching with HF using a photo-resist masking method. A layer 21 of silicon dioxide is then vapour deposited, e.g. by pyrolytic hydrolysis of silicon tetrabromide, over the entire surface, and is subsequently lapped or etched down to the upper surface of the layer 11, leaving the channels filled. A new silicon dioxide layer is then applied to the device surfaces, and openings 22 are provided therein by masking and etching to enable metal contacts to be made, interconnections being applied to complete the circuit. In an alternative embodiment a silicon dioxide layer (27), Fig. 6 (not shown), is provided between a monocrystalline silicon layer (25) and a polycrystalline layer (26) vapour deposited thereon. The method of the previous embodiment is then applied to the layer (25), the channels being etched down to the oxide layer (27).

Abstract: 1368929 Developing surfaces INTERNATIONAL BUSINESS MACHINES CORP 10 May 1973 [30 June 1972] 22279/73 Heading G4A Data processing apparatus for developing a three dimensional object represented by a vertex list and topological map stored in a memory performs the following steps: (1) calculation from the stored data of the equations of planar surfaces on the object; (2) calculation, from these equations, of the orthographic projection of each surface in the direction of its surface normal and storage of each projection as the image of the associated surface on a development plane;  (3) formation of a table of surfaces in which each edge of the object lies; (4) development of a first surface, a label associated with the surface which is initially set to "-1" representing non-development being set to "1"; (5) location of all surfaces adjacent to that surface and setting their label to "0"; (6) a scan of the labels to find a surface with the label "0", the orthographic projection of this surface then being shifted and rotated to bring it into a position tangential to the already developed first surface;  (7) location of all surfaces adjacent to this second surface, their labels being set to "0", the value of the label associated with the second surface being set to "1"; and (8) continuation of the scan of the surface labels until all the labels are at "1" when a development in the development plane is complete. As described alignment is effected by finding an edge on the surface having the label "0" which belongs to an already developed surface. A point on this edge common to both surfaces is then chosen, the orthographic projection of the undeveloped surface being first shifted so that the points coincide and then rotated by the angle between the orthographic projections of the common edge to bring the two projections into the required position on the development plane. If there is an overlap between two surfaces after the projection of the second has been aligned with the first the scanning proceeds to a further surface leaving the label of the surface overlapped at "0". When all the images have been formed in the required manner in the development plane the development of object may be drawn by a digital plotter controlled by the data relating to the images. A program is described for performing the necessary operations.

[Class 3 (ii)] [Also in Group XX] An announcement slide is made by applying to a glass plate a transparent or translucent patterned' coating or background in which the display matter is to be cut, the cutting being effected through a protective medium which prevents chipping and which is removed after the cutting operation. A transparent glass plate A is coated on one side with a covering B of a translucent paint or varnish, e.g. by means of an air-gun or air-brush. Stencils may be used to give appropriate geometric designs and shaded effects. A second layer C of a composition containing size powder, gelatine, whiting, zinc white; water and dye is then applied. This layer is allowed to dry and parallel lines D or other patterned lines are marked thereon with a composition of indigo, glycerine, plumbago and water. The announcement is subsequently inscribed by means of a stylus knife &c., and the outer covering C removed by washing with water. The patterned backing may-be tinted or coloured and the slide is of heat resisting material and may have rounded corners. Continuity in the patterned background during projection is obtained by providing glass plates which overlap the adjoining edges of the slides, the outer edges being secured together by adhesive strips. Specifications 216,349, [Class 98 (ii)], and 421,132 are referred to.
