Abstract: 1,086,891. Injection moulding capacitor casings. DUBILIER CONDENSER CO. (1925) Ltd. Oct. 1, 1964, No. 39910/64. Heading B5A. [Also in Division H1] A rolled capacitor A (see Division H1) is impregnated with e.g. partially polymerized styrene and located in an injection mould, Fig. 5, by a partial sleeve C of preformed plastic material placed in the lower half of the mould, which defines a cylindrical cavity B<SP>2</SP> accommodating the capacitor, smaller shaped cavities at the ends of the main cavity, and outer narrow apertures B<SP>4</SP> gripping the terminal wires A<SP>2</SP>. A thermoplastic material, e.g. polyethylene or polypropylene is injected at B<SP>5</SP> to enclose the capacitor and form beaded bosses (D<SP>1</SP>) projecting from the ends of the casing. Alternatively the capacitor may be moulded with a casing extending as a flexible sleeve of small diameter along the terminal wires; the unit being located in the mould by a pre-formed plastic insert grooved at the ends to locate the terminal wires (Figs. 7, 8, not shown). Alternatively the beaded bosses or flexible sleeves may be preformed of similar plastic to the casing and inserted in the mould over the terminal wires so as to bond with the casing during injection moulding (Figs. 9, 10, not shown). A suppressor capacitor H, Fig. 11 (not shown), has a terminal wire (H 1 ) soldered to one end and a flexible insulating coating of non-bonding material is threaded over wire (H 1 ). A plastic casing (J) of e.g. propylene with a boss (J 1 ) surrounding the wire is injection moulded over the capacitor, shrinkage of the boss on cooling, gripping and sealing the coating of the wire.

Abstract: 1516887 Magnetic storage devices INTERNATIONAL BUSINESS MACHINES CORP 3 Oct 1975 [31 Dec 1974] 40520/75 Heading H3B A magnetic bubble chip, Fig. 1, is formed by applying a patterned magnetic layer of mainly contiguous NiFe or permalloy discs 18, 28, 32, 38 over a bubble-supporting magnetic medium 10 such as a garnet of the general composition Gd 0À6  Y 1À7  Yb 0À7  Ga 1  Fe 4  O 12 , using the magnetic layer portion which defines a propagation area P as a mask for ion implantation 16 of the magnetic medium adjacent the contiguous discs, and using a critically positioned mask to form a patterned layer 20, 24, 34, 46 of electrically conductive material. e.g. gold, over the magnetic layer and the bubble supporting magnetic medium. The propagation area P comprises a major loop and two minor loops, each loop being formed by a row of contiguous magnetic discs along the periphery of which magnetic bubbles B are moved by an inplane rotating magnetic field H. Bubble transfer between the loops is effected by energizing a conductor 46. In addition the chip supports a bubble generating area G comprising a magnetic disc 18 and a conductor 20, a sensing area 5 comprising bubble stretching magnetic disc rows 28, 30, 32 and a divided conductor 24, and a bubble annihilation area formed by spaced magnetic discs 38. Magnetoresistive readout is effected by passing a current through disc row 32, electrical insulation between the row and the conductor 24 being provided by a SiO layer 40. In the constructional process an SiO layer may be deposited immediately on the magnetic material 10, while the disc patterned magnetic layer 18 is defined by evaporation or sputtering deposition, followed by the deposition of a plating base and photoresist masking. An ion implantation masking layer is then deposited in the areas not coated by the photoresist. Removal of the photoresist is next effected, followed by the splutter clearance of the underlying plating base and magnetic layer portions. Ion implantation is effected at this stage by impinging H+, B<SP>+</SP> or Ne<SP>+</SP> ions upon the structure, following which the ion implantation masking layer and plating base are removed to expose the required pattern of magnetic discs. After providing an insulating layer 40 over the sensing area an overall conductive layer is deposited on a critically positioned photoresist pattern. To form the required conductor pattern the photoresist and overlying conductive material is lifted off.

In a hot or cold-extrusion press having a cylindrical chamber 1, a fixed die 2 at one end and a movable ram 9 at the other end, there is provided between the ram and billet 6 a spherical or part spherical member 7, the maximum cross-sectional area of which is greater than the maximum cross-section of the mouth of the die, and which transmits the ram pressure to the billet. The pressure member 7 is preferably of a softer material than that of the chamber wall, In a modification, a shoulder (not shown) is provided in the conical portion 10 of the ram which seats a sealing ring. It is stated that the use of a spherical or part spherical member distributes the ram pressure so that the maximum force is applied along the billet axis, which creates a new flow pattern in the material which prevents the inclusion of oxides beneath the surface of the extruded rod ; it also results in a residue which is easier to clear from the chamber.

Chamber 35 has inlets for both light and heavy phase liquids and an outlet for only one phase liquid, the other phase liquid being transferred to the second chamber 34 through a passage 36 in the partition for further contacting with a different phase liquid which is introduced into the second chamber. Chamber 34 has outlets for both the liquids. The liquids are introduced and removed from the chambers via passages in the rotating shaft 11. The chambers and their functions may be converted so that a heavy phase liquid may be contacted twice by a lighter phase liquid, as well as a lighter phase liquid being contacted twice by a heavier phase liquid. Figs. 3-7 not shown, show convertible means in the form of an apertured device which fits within the partition 133 and is movable so that in different positions the apertures are aligned with different outlet and inlet ports in the partition. In Fig. 8 not shown the apparatus is adapted for reclarification of the light liquid in chamber 234 (the second chamber) after it has been extracted in the first chamber. Heavy liquid passes out of chamber 235 through a by-pass opening 204 into the outer portion of chamber 234 and then into the heavy phase outlet 231 of chamber 235.
