Title: Quenching process
IPC: C21D1/56
Filed: 1964-02-17
Abstract: A process for quenching hot metal which comprises subjecting the metal in rapid succession first to treatment with an aqueous medium to effect a partial quenching and then to treatment with an organic medium comprising a chlorinated biphenyl compound or a mixture of such compounds. The two media may be successively sprayed on to the metal, or preferably, are employed together in a vessel wherein they exist as separate phases, the aqueous phase which may be brine being the supernatent phase; and the object to be quenched being held therein for perhaps 16-32 secs, prior to being submerged in the lower,organic phase. The latter phase comprises at least50% of chlorinated biphenyl which may contain 20-60%, or preferably 40-50% by weight of combined chlorine and may also comprise a wide variety of other organic substances: e.g. mineral oil, trichlorobenzene-up to 15% by weight of the chlorinated biphenyl present, viscosity modifiers, organic sulphonates, &c.

Title: Superimposition gear
Inventor: MULLER HELMUT
IPC: F16H47/08

Abstract: 1,208,831. Hydro-mechanical variable-ratio epicyclic gear; variable-ratio gear and clutch combination. VOITH GETRIEBE K.G. 9 Feb., 1968 [25 Feb., 1967], No. 6618/68. Heading F2D. An hydromechanical variable-ratio epicyolic gear, particularly for a power station boiler feed pump drive, comprises a sun-ring train, two elements of which are connected to input and output respectively, and a third of which is connected to input via an hydrodynamic torque converter, the output speed of which is variable by adjustment of variable angle reactor blades. As shown, a driving engine shaft is connected to a ring 7 through a scoop-controlled fluid coupling 4, bridgable by a friction clutch 3, and a shaft 5. The latter also is connected to drive a carrier 10 through a gear train 12-14, a torque converter 16, and a gear train 21, 22. The torque converter is flange-mounted on a gear casing 25. The torque converter turbine 18 and hence the carrier 10 are one-way detained at 24 to provide a basic speed at which, to improve efficiency, the reactor blades are closed or the converter is emptied. Overdrive, above the basic speed, is by operation of the torque converter, the clutch 3 being advantageously engaged to bridge the fluid coupling 4. Speeds below basic are obtained by regulation of the fluid coupling scoop pipe 26. In Fig. 3 (not shown), the carrier 10 is driven through one of two selectively fillable torque converters to provide two ranges. The torque converters may be designed for differing output speed or power ranges, and/or followed by differing gear trains. In Fig. 4 (not shown), wherein the fluid coupling is dispensed with and speed regulation is obtained for overdrive above basic speed only, the carrier and sun are respectively input and output connected and the ring is connected to input via a variable output speed torque converter. A friction band-brake on the ring is applied for basic speed.

The cathode has endplates 38 closing the discharge space, and the heater leads 30 are brought out along the midplane of a resonator, as shown in Fig. 1, to minimize coupling with the field; these may also incorporate tuned coaxial-line rejector circuits. The cathode may be self-heated in operation by bombardment of returned electrons. The cross-section of the resonators may be varied from the circular in order to increase or reduce the mutual " coupling " between them ; forms are illustrated with oval, horseshoe or slotted shape. When more than one coupling loop is employed, they are brought into the same phase by interposing coaxial lines of adjustable length, Fig. 6 (not shown).

Title: Diode structure in semiconductor integrated circuit and method of making same
IPC: H01L21/761
Filed: 1965-02-17
Abstract: 1,046,152 Semi-conductor devices. WESTINGHOUSE ELECTRIC CORPORATION. Feb. 17, 1965 [March 6, 1964], No. 6837/65 Heading HIK. In a semi-conductor integrated circuit structure comprising transistor and diode portions in a layer with isolated portions, the thickness of the " base " region of the diode is made greater than a diffusion length to reduce the tendency for transistor action to occur in the diode. The structure may be made by masking a P-type substrate 110 (Fig. 5, not shown) with oxide, depositing P-type impurity 214 in selected areas, removing the mask, epitaxially depositing N-type layer 212, masking, depositing P-type impurity on regions 314, 216, removing mask, epitaxially depositing N-type layer 312 and again masking and depositing P- type impurity on regions 414, 316a, 316b. The structure is then heated to diffuse the P-type impurity into regions which merge together to form the structure shown in Fig. 2 which comprises a diode formed by regions 118a and 116a, and a transistor having emitter zone 118b, base zone 116b and collector zone 112b. The diode and transistor are separated from each other by PN junctions formed by isolating P-type zones 114 which extend to the P-type substrate 110. The thickness of P-region 116a in the diode is greater than a diffusion length to prevent transistor action which might occur particularly if under circuit conditions a bias is applied to N-region 112a to ensure isolation by PN junction 112a/114, 110. The resistivity of region 112 may be varied such as by first using arsenic (10<SP>16</SP> atom/cc. concentration) for layer 212 and then phosphorus (10<SP>15</SP> atoms/cc. concentration) for layer 312; the semi-conductor material may be silicon. The diode region 118a is of relatively high resistivity to improve breakdown voltage. Surface impurity concentrations for the various zones are quoted. A circuit suitable for the input circuit of a logic circuit as described in Specification 1,023,565 utilizing the device is described.
