Title: Improvements in or relating to circulator devices for steam boilers
IPC: F22D7/02
Filed: 1924-02-20
Abstract: 219,608. Owen, L. E. Feb. 20 1924. Partitions and baffles in water space. - Circulator devices for Lancashire and like boilers of the kind comprising tapering casings resting on segmental bearer strips on the furnace flue are constructed with a central gap in the front and rear bearers. The outlet end of the saddle is situated above the water line and has a downwardly-projecting hood. The casing c, Figs. 2 and 3, is secured to segmental strips d<1>, d<2> by bolts riveted at h<2> to the strips. A space e is left between the strips at the rear end, and a corresponding space exists at the larger front end the segments adjacent the space being connected by bolts. The casings are formed of longitudinal sections c<1> and are held in position on the flues by chains g. When the boiler has two flues, the two casings may be connected by turning the bottom edge of one over the corresponding edge of the other. The casing extends above the water-line at the discharge end and has a deflecting hood i.

Title: Improvements in or relating to a method of mounting and assembling tooth wheels on metallic hubs
IPC: B22D19/00
Filed: 1929-05-17
Abstract: 327,376. Durand, P. May 17, 1929. Divided on 329,170. Casting processes. - A bronze toothed crown is assembled on a steel or other metallic hub by fitting or shrinking the crown onto the hub and casting additional metal of softer or the same composition as the bronze, into a slight chamfer or peripheral notches on each face of the hub and alternating on its two faces, until fusion of the crown takes place, which on solidification ensures intimate connection of the parts. In Fig. 1, a conical fitting of say 1.5‹ is first formed and a funnel of moulding sand s, provided with an overflow t, placed over each notch k, in the hub a<1>. Molten bronze is added according to the trajectory # until the part u becomes fused. When the hub is itself made of bronze, which may be of a softer quality, the notches are replaced by a slight chamfer formed here and there by milling on each face of the hub. The method is applied to assembling the crown on a differential gear casing. Specification 329,170 is referred to.

Title: Improvements in semiconductor devices
IPC: H01L29/00
Filed: 1970-01-30
Abstract: 1,263,042. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 30 Jan., 1970 [10 April, 1969], No. 4505/70. Heading H1K. A semi-conductor layer 1 comprises area 2 containing a conventional monolithic circuit including PN junctions covered by a layer 3 of insulation, e.g. a thermic oxide superimposed on which is a phosphosilicate layer 4, carrying conductive lands 5, 6, 7 conventionally connected to the semi-conductor. The assembly is encapsulated by layer 8 of glass or silicon nitride carrying terminals 9, 10, 11 formed by photolithography and etching to supply operating voltages to lands 5, 6, 7 through layer 8. Further layers similar to 3 may be superimposed. A conductive electrode 12 on the surface of layer 8 is connected to negative terminal 9 over lead 13 (which may be a high resistor) and overlays area 2, whereby mobile positive charge centres derived from the encapsulation layer 8 and the thermal layer 3 are attracted, and thus prevented from reaching and contaminating the semi-conductor, where they would otherwise cause inversion of the P-type areas and increase of leakage current. The electrodes and terminals may be Cr-Cu-Au or Mo or Al.  An FET (Fig. 2) may comprise a P substrate 1, N areas 2a, 2b as source and drain, and passivation layer 31 incorporating an active gate oxide region, covered by encapsulation layer 8<SP>1</SP> of glass or silicon nitride and phosphosilicate layer 4<SP>1</SP>; an electrode 12<SP>1</SP> attracting positive mobile charges which may be energized from a separate negative source. Alternatively (Fig. 3, not shown) the negative electrode may be deposited on passivation layers and covered by the encapsulation layer. In fabrication, the mobility of contaminants is increased by applying a negative voltage to the electrode and heating to 100-300 C. for 1-2 hours.  A mathematical analysis is given.

Abstract: 111,039. Bendix, V. March 29, 1917. Turning-gear.-In power turning-gear of the type described in Specification 20,811/14, comprising a pinion 6 mounted on a motor-driven shaft 5 for longitudinal movement into engagement with a member of the engine to be started and rotary movement with the shaft, the pinion 6 and the driving-connexion between the shaft 5 and the motor are at opposite ends of the motor. In the form shown, the screw shaft 5 passes through the hollow armature shaft 2 of the motor 1, and the driving-connexion between the shafts 2, 5 is a spring 8. The pinion 6 is prevented from rotating, except when in mesh with the fly-wheel 13, by a yoke 16 fitting in a groove 6<a> in the pinion. The yoke 16 has arms 16<a>, which slide along a fixed plate 17 and are adapted to bridge contacts 19 when the pinion is in engagement with the flywheel 13. The contacts 19 are in an alternative circuit including the motor, so that the hand switch may be released without stopping the motor. The screw shaft 5 may be mounted in bearings beneath the motor 1, from which it is driven through reduction gearing, and the pinion 6 may be arranged to travel away from the motor in the meshing operation.

Initially to store an m byte word held in register 7 in one line of one column of units 2, the associated digit line 5 is enabled and the combined information in register 11 and in each group 9 of bistables is decoded to a signal on one line 4 for each unit 2 in the selected column, a binary signal being stored at the intersection of the lines 4, 5. Further words may be stored in the same line by changing the information in register 11. To read out data, if the interrogation code for register 11 is known a single access to the associative memory will result in an output signal from one of the detectors 10 associated with the line in which the data is stored which together with the complementary code determines the storage location of the required data. If the interrogation code for the secondary register 11 is not known, by cycling the register through its 2<SP>1</SP> positions until an output is obtained from a detector 10, the location may be determined.

Granular materials are separated according to their density by use of a liquid of intermediate specific gravity in a rotating cylindrical vessel, a series of members being provided which rotate with the vessel so as to move the lighter floating particles to a point within the vessel and lift them circumferentially from that point to a position from which they can be discharged. The material to be separated is fed by a shoot E disposed through an open end C of the vessel which contains the separating liquid to the level D. The sinks are lifted by pockets to a position where they discharge down a shoot G, the pockets being formed by perforated radial members F which are provided with helically-disposed portions for facilitating the collection and discharge of the sinks. As the vessel rotates, the floating materials are transported to the opposite end of the vessel from where they enter by the action. of partly helical members H which constitute pockets arranged to extract and lift the floats and discharge them down a shoot L ; the members H are supported by perforated radial and cylindrical members K and J, the latter being spaced from the shell of the vessel by helical members M which serve to circulate the liquid back towards the other end of the vessel. Both the members F and H may be inclined in a radial direction and, if desired, of curved construction. Fig. 4 shows a vessel divided into two parts for separating material into three fractions. The sinks from the first part are transferred by shoots G, N to the second part which contains a liquid of greater specific gravity than the first and is arranged to discharge the floats down a shoot LX and sinks down a shoot GX.
