Abstract: A subscriber unit of a time division multiple access (TDMA) radiotelephone system is, from a power consumption standpoint, reconfigured in each time slot of a TDMA frame to a power consumption tessellation in which subscriber unit circuit components not needed for communication signal processing in that time slot are powered down, and other components are powered up.Some circuit components are powered down by switching their power supply circuits. In order to minimize the extent of circuitry that must be provided to distribute power consumption control signals, other techniques (which utilize circuitry provided for other purposes), such as clock frequency control or power down commands, also are utilized to modify controlled circuit component power consumption without actually controlling power supply circuits. Loop connection length between the subscriber unit and the subscriber's telephone set, or other terminal equipment, is limited to a length which is much less than the length of a radio link on which the subscriber unit operates. Programmable ring frequency logic controls the frequency of a ringing signal generator, and a high frequency ring control signal is switched on and off in the cadence of ringing operation. Also an expansion header is provided to enable serving plural subscriber loop circuits with the same radio equipment for reducing per line power consumption.

Abstract: 1,095,412. Making IGFET. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 4, 1965 [Aug. 26, 1964], No. 33292/65. Heading H1K. In the manufacture of an IGFET impurities are introduced into the gate insulation which is then subjected to an electric field while the transistor is heated. This process leads to a redistribution of charges in the insulation and consequent alternation of the induced charge carrier density in the channel region. The Specification describes a transistor formed on a high resistivity silicon body and having phosphorus diffused source and drain regions and having grown oxide gate insulation. Before the application of the metallic electrodes the transistor is heated in an oxygen atmosphere into which is introduced a boron or aluminium compound which decomposes to form a layer of oxide on the silicon oxide gate insulation. The layer material is diffused into the insulation, and gate, source and drain electrodes applied by vapour deposition. By applying a suitable uniform electric field between gate electrode and substrate and suitably heating the structure the characteristics of the transistor may be made of the deep enhancement type or deep depletion type or any intermediate type. These characteristics remain stable during normal operation of the transistor. If during the treatment potentials are also applied to the source and drain electrodes it is possible to produce a shaped conduction channel. An apparatus is described (Fig. 2, not shown) which is used for applying the heat-field treatment to a plurality of transistors on a single substrate so that each may have a desired type of characteristic.

Suitable naphtha feeds are straight-run, thermallycracked or catalytically cracked naphthas and can be first hydrogenated using a catalyst of cobalt oxide and molybdenum oxide on alumina to remove sulphur. A number of reforming reactors can be arranged in series so that a reactor can be by-passed whilst its catalyst is regenerated.

Abstract: 1,229,045. Semi-conductor devices. MOTOROLA Inc. 23 April, 1968 [9 May, 1967], No. 19029/68. Heading H1K. A monolithic integrated circuit structure comprises voltage distribution ground planes constituted by a substrate 25 (Fig. 20) of one conductivity type and an overlying layer 38 of opposite type graded from low resistivity at its junction with the substrate to higher resistivity where it underlies a number of mutually isolated surface regions 45 containing device structures. Portions 51, 54, 59 of the same conductivity types as the ground planes extend to the surface where they can supply operating and signal voltages to the devices via metallized tracks. The illustrated structure is made by first forming N + and P+ inclusions in the substrate by oxide masked diffusion and burying them beneath a P+ epitaxially grown layer. Further N + inclusions are diffused over the first set and buried beneath a P - epitaxial layer. N + + and P+ diffused inclusions are formed in this and buried under an N-type epitaxially grown layer 45 and N + and P + inclusions diffused into this. During epitaxial growth the P+ inclusions formed after the P - layer and all the N+ inclusions merge as at 51, 54, 59 to provide surface access to the P - layer and substrate, through which the voltages are supplied, and to isolate sections of the epitaxial N layer. In this example a bipolar transistor and P type resistor are formed in the isolated sections and are interconnected as an amplifier and supplied with voltage via metallized surface tracks.

Abstract: 1,232,827. Converters. FRIED. KRUPP G.m.b.H. 20 Sept., 1968 [21 Sept., 1967], No. 44871/68. Heading F4B. The supporting ring 1 of a tilting metallurgical vessel (not shown) is formed from two halves 2, 3, joined together in the plane containing the tilting axis 15. The halves are formed with abutting flanges 8 and radially outwardly extending projections (Fig. 2, not shown) at their ends, which when the halves are mated together define a cylindrical surface over which the annular flange 12 of pivot pin 10 is a shrink fit. Bolts are mounted through bores 14 to further secure together the pivot pin and the supporting ring halves. The end projections and the annular flange fitting around them may be tapered to improve the fit. In a modification (not shown) instead of a pivot pin, a tilting ring is fitted around the cylindrical surface defined by the abutting end extensions of the halves, to secure them together.
