Abstract: 1,270,878. Die-casting machines. R. E. CROSS. 21 Oct., 1969 [22 Oct., 1968; 10 Oct., 1969], No. 51547/69. Heading B3F. A die-casting apparatus comprises a plurality of relatively movable die elements 111, 112, Fig. 3, which when abutting at a parting surface P define a metal feed system which includes a sprue 121, an injection cylinder 135, and a runner 126 leading to a mould cavity 115, means 142 movable to isolate the cylinder 135 from the sprue inlet 122, and a piston 138 for forcing molten metal into the mould cavity 115. The arrangement is such that any solidified metal in the feed system can be extracted at the parting surface when the die is open. Molten metal is poured into the sprue 121 until the injection cylinder is filled, plunger 145 operated to close off the cylinder from the sprue inlet, and the metal forced into the cavity 115 by movement of piston 138. In an embodiment, Fig. 6, three die elements 411, 412 and 413 are provided, the element 412 being movable; element 413 is slidably mounted on the fixed element 411 by pins 425, but is normally locked to the element 411 by means 426. The two elements 413 and 411 are only moved apart when it is necessary to remove solidified metal from the sprue 435. The plunger 450 acts both as the injection piston and as the means for isolating the sprue inlet 436 from the injection cylinder 441. In another embodiment, Fig. 5, one die element 312 is provided with a frustoconical projection 350 and the other die element 311 is provided with a recess 325 to mate with the projection. Molten metal is poured into the sprue 321, flows through an extension 341 of the sprue formed in the upper surface of the recess 325 into a notch 340 in a face 326 and thus into the injection cylinder 330 and shot well 355. Operation of the plunger 338 closes off the pouring sprue connection and forces the molten metal through a notch 357 and runner segments 360 and 361 into the mould cavity 315. An ejector pin 365 communicates with the base of the shot well 355.

Abstract: 1331642 Filtering of cleaning liquid DOW CHEMICAL CO 5 Nov 1970 [5 Nov 1969] 52752/70 Heading B1D [Also in Division C1] An aqueous alkaline metal salt solution containing up to 5% soluble oil and used to clean machined metal parts while leaving a thin oil layer thereon is continuously cleaned by filtering through a filter aid layer which removes particles of 0.1 to 10 microns major diameter upwards, the filtering cycles between successive backwashes being considerably extended by adding an aminopolyacetic acid or an amine, ammonium or alkali metal salt or soap thereof to the solution. Enough is added to reduce the unchelated hardness of the solution to between 0 and 400 ppm, expressed as Ca CO 3 , or to neutralise the hardness leaving up to 2% of free additive in the solution. Additive is added periodically to maintain these conditions, the solution being held at from 70F to boiling point. Preferred additives are ethylenediaminetetracetic acid, N- - hydroxyethylenediaminetetracetic acid, N - hydroxyethylene - acetic acid, nitrilotriacetic acid, N-2-hydroxyethyliminodiacetic acid, cyctohexanediaminetetracetic acid and their salts, typically sodium salts. The filter acid is diatomaceous earth and is applied to a multi-tube filter connected in series between tanks for clean and dirty solution. Further filter aid may be added to the liquid being filtered periodically without cleaning the filter.

Abstract: 1448525 Schottky barrier diode INTERNATIONAL BUSINESS MACHINES CORP 16 Dec 1974 [28 Jan 1974] 54169/74 Heading H1K A schottky barrier diode comprises a metal electrode 8 in rectifying contact with a semiconductor substrate 1 producing a depletion region 9 when it is reverse biased, a first dielectric layer 2, 3 over the edge of the depletion region 9 and surrounding the electrode, and a conductive layer or portion 4 also surrounding the electrode and insulated therefrom by a second dielectric layer 6. The electrode 8 is of aluminium and the first dielectric layer comprises thermally grown silicon oxide 2 and pyrolytic silicon nitride 3. The substrate 1 is of silicon and the conductive layer 4 is of N+  doped polycrystalline silicon with a thermally grown oxide second dielectric layer 6. A further layer 7 of pyrolytic silicon oxide is also deposited prior to the electrode deposition. The conductive layer 4 acts as a floating gate, and is permanently charged. This is achieved, e.g. as a manufacturing step, by successive avalanche breakdowns at increasing reverse bias potentials applied to the electrode 8. Electrons at the edge of the depletion region 9 are injected through dielectric layers 2, 3 and on to the conductive layer 4. This depletes the underlying substrate thus widening the depletion edge 10. Successive breakdowns result in a final equilibrium state representing an increased reverse breakdown potential.
