Title: Semiconductor devices
IPC: H01L27/22
Filed: 1973-04-13
Abstract: 1447989 Semi-conductor devices FERRANTI Ltd 11 April 1974 [13 April 1973] 17882/73 Heading H1K A semi-conductor device, e.g. the JUGFET 11 shown in Fig. 1, within a semi-conductor body comprises a shallow epitaxial layer 12 on a substrate 13 of the same one conductivity type, the device including a region 18 of the epitaxial layer defined by a heavily-doped opposite conductivity type boundary layer 20 and a buried layer 19 of opposite conductivity type at the interface between the defined region 18 and the substrate 13, wherein a further region 21 of opposite conductivity type is provided in a surface portion of the defined region 18, the remaining surface portions of region 18 being heavily doped as at 36 with the one conductivity type impurities so as to be contiguous with the region 21 on the surface but not to underlie the region 21 within the body of the semi-conductor. The construction of the JUGFET 11 is similar to that of a collector-diffusion-isolation bipolar transistor 10 shown in Fig. 1 in an integrated circuit combination with the JUGFET 11, the basic difference being that the emitter 17 of the bipolar transistor 10 is completely surrounded within the epitaxial base region 16 by the heavily doped layer 37, whereas the JUGFET gate 21 is only encircled by the heavily doped layer 36 on the surface. An alternative device of basically similar construction is shown in Fig. 2 and comprises a Hall-effect generator having a plate within the defined region 41 of the epitaxial layer 42, in the surface region of which selected parts 41 are doped with opposite conductivity type impurities and the remaining parts 47, 48 selectively being heavily doped with the one conductivity type impurities to form contact regions for the device. The effective thickness of the plate is defined between the depletion layers 57 and can thus be advantageously controlled depending on the potential differences across the P-N junctions.

Title: Improvements in or relating to Level Indicators
Inventor: FIELDEN JOHN ERNEST
IPC: G01F25/00
Filed: 1966-04-25
Abstract: 1,174,395. Electro-physical measurement - fluid level. FIELDEN ELECTRONICS Ltd. April 24, 1967 [April 25, 1966], No. 17970/66. Heading G1N. A capacitance level gauge output is rendered independent of the di-electric constant of the material being measured by having, in addition to the measuring electrode 3, Fig. 1, which extends over the range of levels to be measured, a second electrode 6 which is below the minimum level and therefore always immersed, and arranging converters 7, 8, to produce D.C. signals proportional to the respective capacitance variations and supply them to a self-balancing bridge. The converter 8 produces a direct current dependent upon the variation of capacitance 6 due only to variations in di-electric constant, and energizes the bridge, which consists of two series resistors 26, 27 in parallel with two parallel resistors 28, 29, the resistor 28 being adjustable for calibration, and the resistors 27, 29 having sliding taps 30, 31 between which the bridge output is taken. This output is compared with the D.C. voltage output of converter 7 which depends upon capacitance changes due largely to level changes, but also to di-electric changes. The difference signal drives a motor 33 to rebalance the bridge (at 31) and to operate a pointer 34, the converters 7, 8 once the resistors 27, 28 being adjusted so that di-electric dependent changes in voltage cancel. The converters are basically similar, and each comprises Figs.2, 3 (not shown) a periodically operated switch (13) which connects the appropriate electrodes (3, 6) alternately to a D.C. source (11) and then to a capacitor (12) into which it discharges. The mean voltage on the capacitor (12) is compared with a second D.C. source (15) and after smoothing (16, 17, 19) passes to an amplifier (18). A feedback resistor (21) is connected to one input of the amplifier from the output of the amplifier (Fig. 2) where a capacitance dependent voltage E out  is required, and from a potential dropping resistor (25, Fig. 3) in the return path of the amplifier output, where a capacitance dependent current I out  is required.

Title: Burglar and like alarms employing thermionic oscillations
IPC: G08B13/26
Filed: 1930-06-11
Abstract: 353,627. Burglar alarms. FROMY, E. M. F., 96, Boulevard du Montparnasse, Paris. June 11, 1930, No. 17976. Addition to 349,496. [Class 118 (i).] The parent Specification describes a burglaralarm in which the earth - capacity of the burglar releases an oscillatory circuit so as to give an alarm. According to the present invention the valve V tends to oscillate in consequence of the reaction coupling L, L2, but is normally prevented from doing so by the closelycoupled control-circuit L1, C1, which is in tune with the grid circuit L, C. When, however, the circuit L1, C1 is thrown out of tune by the proximity to the protected object P of an earthed burglar, who increases the effective capacity of that circuit, oscillations take place, the anode current falls off, and the relay r releases so as to close the alarm circuit. The system may be energized from the mains A, B through a resistance R1 which adjusts both plate- and filament-voltage; and a hydrogeniron or other regulating-resistance may be employed, Fig. 3 (not shown). Alternating-current mains may be used, Fig. 4 (not shown), and the condenser C1 may be omitted in suitable circumstances. To prevent the burglar from disabling the alarm-circuit, the leads 4, 5 may be extended so that the relay r is close to the alarm device. If then the leads be cut or short-circuited the alarm is operated, Fig. 5 (not shown). The burglar could prevent this by connecting one of the leads to one of the mains, but is frustrated, Fig. 6 (not shown), by a metal sheath enclosing that lead and connected to the other main. In a further modification, Fig. 7 (not shown), several apparatus of the kind described may control a single alarm circuit through an intermediate circuit, protected by metallic sheathing as described above, and passing in series through the armatures of several relays r of the control apparatus.

In a method of hotworking metals a rough product is first formed by extruding or piercing, using a vitreous lubricant such as glass which remains as a coating during further hot deformation operations such as rolling to form the final product. In making a turbine blade section a bar 11, Fig. 3, is extruded to a section with a rounded trailing edge 12 using a vitreous lubricant and the section while still hot and coated with a layer of the lubricant is rolled to the final section, Fig. 1, having a sharp trailing edge. In another example, tubes extruded with the lubricant are fed over a mandrel and immediately rolled to the required final size without an intermediate heating operation.

Abstract: 1521401 Installing marine structures SOC NATIONALE ELF AQUITAINE. (PRODUCTION) 4 May 1976 [7 May 1975] 18228/76 Heading E1H An offshore structure is installed onto an underwater bed by towing the base to the site and then submerging the base onto the seabed whilst successively attaching columns end to end pivotally as the base is sunk. The columns have floats at each end which are differentially ballasted when rotating them from the horizontal to a vertical position after connection. As described the base is a tank 32 for the storage of hydrocarbons and is firstly submerged to a depth where one end of a first column 2a may be pivotally connected to it. Initially the column 2a is floating in a horizontal position (not shown) and after connection, as the base is sunk, it pivots to a vertical position. The column 2a has annular ballastable floats 10, 12 and its pivotal movement to the vertical position is facilitated by transferring ballast from float 12 to float 10. Similar steps are performed to successively connect similar columns 2b and 2c. The column 2c has a platform 52 carrying a loading arm for loading ships and each of the columns 2a 2b 2c has a duct which when interconnected provide a conduit between the tank 32 and the platform.
