IPC: H01L29/00
Abstract: 1,047,378. Transistors. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Sept. 17, 1965 [Sept. 18, 1964], No. 39736/65. Heading H1K. The collector zone of a transistor is commonly heavily doped adjacent the collector electrode and more lightly doped adjacent the collector junction. The higher resistivity adjacent the junction improves the breakdown voltage but detracts from the amplification factor, particularly at high currents. This latter disadvantage is obviated by the invention which provides a further heavily doped region within the lightly doped region and immediately adjacent the junction. Such further region is thin and follows the course of the junction. Fig. 1 (not shown) depicts an NPN planar transistor in which on an N+ substrate an N- layer has been laid, e.g. epitaxially, and part of the surface of this layer has been converted into N+ type by diffusion of further N-type dopant through an oxide mask. Into the diffused N+ region, through the same mask, a P-type base region has been diffused and finally an N-type emitter has been diffused into this through a second and smaller mask. Both masks are left in position to protect the surface junctions. By suitable etching of a similarly produced structure, an alternative mesa-type embodiment may be obtained.

Abstract: 1,053,373. Random storage of record tapes. ASSOCIATED TELEVISION Ltd. March 13, 1963 [Dec. 14, 1961], No. 35496/63. Divided out of 1,053,372. Heading G5R. The disc 105 carries skein-rollers 107 and support rollers 108 and is driven by a motor 104 controlled by a switch S11. Tape tension is sensed by a roller 115 and when this is relieved, particularly by activation of a capstan 113 tape is wound about the turns already wound until the tape tension is restored to a preferred value. Where the store receives tape on which dictation has been recorded by head 112 for later transcription in conjunction with a playback head 118 and a capstan 119 in the manner of the parent Specification (the open ends of the tape go to a second random store to form a continuous loop), the tape, lubricated by graphite if required, is withdrawn firstly from the few turns stored about a fixed drum 111 and then over one of the rollers 107 from the inside of the stored skein, the disc 105 being pulled backwards. Tension sensed by a roller 117 actuates a limit switch S12 controlling capstan 119 when all the available tape has been withdrawn, In an alternative embodiment (Figs. 3, 4, not shown) the outer turns of tape are stored, not about skein rollers 107, but about a ring similar to 111 but driven by a motor sensitive to both over- and under-tension. A long dancer-arm provides for limited backspacing of the tape.

Abstract: 1,228,949. Gas turbine engines; jet nozzles. ROLLS-ROYCE Ltd. Oct.10, 1969 [Oct.16, 1968], No.49129/68. Headings F1G and F1J. A gas turbine engine comprises sensor means for sensing engine rotational speed or an engine variable which varies in sympathy with that speed, and control means which are brought into operation by the sensor means only when the speed is at or below idling speed, and which brings about an increase in the gas temperature in or downstream of the engine combustion equipment to an extent sufficient substantially to eliminate the presence of free carbon in the exhaust gases discharging from the engine. In Fig. 1 a device 21 is provided to sense the rotational speed of the engine or the compressor discharge pressure, this pressure being proportional to engine speed, and the device 21 acts to control a valve 20 in a blow-off line 16 connected to the outlet of the compressor 12. The arrangement is such that when the speed is below idling speed, the blow-off valve is open so that the mass flow through the combustion equipment is reduced and the temperature therein will rise so as to eliminate the presence of free carbon in the engine exhaust gases. In Fig.2 a gas turbine jet engine is shown having a device 21 as in Fig. 1 but the device is connected to an actuator 23 which controls the position of an orificed plate 24 with respect to the propulsion nozzle 15. At normal speeds the plate 24 would be in the position indicated in full lines in which it is clear of the nozzle outlet, but when the speed is at or below idling speed, the plate 24 will be moved to the position shown in broken lines adjacent the nozzle outlet so that the nozzle area is effectively reduced and thus also the mass flow through the combustion equipment whereby the temperature is increased to a value sufficient to eliminate the presence of free carbon in the exhaust gases. The engine may alternatively be a gas turbine propeller engine having a propulsion nozzle.

Abstract: 1,229,274. Transistor amplifying circuits. R.C.A. CORPORATION. 1 Nov., 1968 [3 Nov., 1967], No. 51958/68. Heading H3T. [Also in Division G3] A transistor circuit comprises transistor 12, Fig. 1, in common-emitter circuit with its collector direct-coupled to the base of transistor 14 which is in common-collector connection: its emitter circuit comprises resistors 22, 24 in series, the base of transistor 12 being D.C. connected to their common point. The arrangement is such that if resistors 22, 24 are in a resistance ratio of n: 1 the voltages at the points 26, 28 are independent of the supply voltage at terminal 16 and of values (n + 1)e and (n + 2)e respectively, where e is the baseemitter voltage of transistor 12. The collector circuit of this transistor may include a Zener diode (Fig. 4, not shown) to stabilize the circuit. As shown, the arrangement comprises a constant voltage source, but by applying an A.C. signal to the base of transistor 12 via a capacitor, from a low-impedance source (Fig. 3, not shown) an amplified output may be obtained from terminal 28, 26 having a stabilized D.C. level. In a second embodiment the emitter-collector path of a further transistor 42, Fig. 2, is connected in the collector circuit of transistor 12, the base of which is earthed for A.C. signals by means of a capacitor 46. This arrangement will transmit the A.C. component of signals applied via terminal 44 to the base of transistor 44, to output terminal 26 the output having the D.C. level (n + 1)e. The arrangement may be used for driving a pair of transistors in long-tailed pair connection, which may function as a limiter.

Abstract: 1,230,657. Rocket type combustion chambers. MESSERSCHMITT-BOLKOW-BLOHM G. m. b. H. Nov.18, 1968, [Nov.20, 1967], No.54610/68. Headings F1J and F1L. The invention relates to a combustion chamber for a rocket or combustion gas generator, there being means for introducing two combustion components tangentially through the peripheral wall of the chamber in the same direction so that they form a combustion vortex. The combustion components are introduced at axially spaced locations so that one component forms a protective film on the peripheral wall at one end of the chamber and the adjacent end wall, while the other component forms a protective film on the peripheral wall at the other end of the chamber and the adjacent end wall, the components re-acting in the central plane of the chamber to form a combustion gas vortex. The rocket unit shown comprises a forward wall 5 integral with a peripheral flange portions 1a, and a rearward wall 6 integral with a peripheral flange portion 1b and with a propulsion nozzle 4, the two parts being secured together to form a flat disc-shaped combustion chamber. Tangential openings 2c, 2a, 2b and 3, 3a, 3b are formed in the peripheral walls 1a and 1b for the supply of fuel and oxidizer respectively into the combustion chamber, the arrangement being such that in operation films of liquid fuel and liquid oxidizer B 1  and S 1  and vaporized fuel and vaporized oxidizer B 2  and S 2  are formed along the peripheral and end walls of the combustion chamber as shown so providing a cooling film between the combustion gas vortex and the combustion chamber walls. In place of single orifices such as 2 and 3, pairs of orifices 2a and 3a may be provided. A ring member formed with an inwardly-projecting flange may be disposed between the peripheral walls 1a, 1b, the flange separating the films of fuel and oxidizer B 1 , S 1 . In Fig.4 in place of separate orifices shown in Fig.1 annular recesses 9 and 10 are formed in the walls 1a, 1b, fuel and oxidizer being injected tangentially into the recesses and discharging tangentially therefrom into the combustion chamber. In Fig. 5 an arcuate baffle 11 is secured to the peripheral wall of the combustion chamber adjacent the fuel and oxidizer injection orifices 2 and 3, the combustion gases discharging from the wedge-shaped space 12 formed by the baffle, in a peripheral direction.

Abstract: 1,230,945. Brakes for roller conveyers. INTERLAKE STEEL CORP. 19 May, 1969, No. 25517/69. Heading B8A. [Also in Division F2] In a braking device for a gravity roller conveyer, a rubber-rimmed roller 7 engageable by a load 2 is connected by cranks 24, 29 to pistoncylinder units 38, 43. These cylinders are sealed at each end, are pivotally mounted at 38b, 43b and contain a liquid such as oil. Each piston, e.g. 36, has a bleed orifice 39. Side plates 8, 9 of the device are pivoted about a shaft 12 and are vertically adjustable to vary the height of the roller 7 relative to main frame members 4. At the other end of the side plates, a spring 22 urges the plates upwardly but the normal position of the plates is such that a shaft 13 is clear of both ends of slots 8b, 9b in the plates. Auxiliary rollers 25 are also supported by the side plates 8, 9. In operation, movement of the piston 36 to the left in Fig. 3 initially causes air to flow, through the orifice 39, to the right. As the piston-cylinder movement continues, the oil level rises and oil flows through the orifice with the air, thus causing increased braking relative to that when the air flows alone. As rotation of the roller continues, the resistance becomes more constant due to churning of the oil and air. To ensure that there is always some resistance to rotation of the roller, the crank arms 24, 29 are out of phase, preferably 90 degrees. Pistoncylinders having different sizes of orifice 39 may be used for varying the braking action.

Abstract: 1,231,985. Cathode - ray display tubes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 6 Feb., 1970 [8 Feb., 1969], No. 5807/70. Heading H1D. In a cathode-ray display tube using at least two beams which pass through two cylindrical electrodes, forming a common focusing lens, at different distances from the axis of the electrodes, the effective boundary between the electrodes lies at axial positions which vary round the circumference of the lens to compensate for the otherwise unequal effect the lens would have on the beams. The tube may be a colour television tube of the shadow mask type using three co-planar beams which are focused and converged by the lens; the electron gun may comprise three cathodes aligned with respective apertures in the first three grids (Fig. 2, not shown) which are followed by the fourth and fifth grids 80 and 81 shown in Fig. 8. The opposed edges of these grids have the same diameter and follow a sinusoidal pattern which prevents astigmatism in the outside beams 84 and 86. In this case the four axial indentations are equal, but the two indentations lying along the vertical axis may be greater than the two lying along the horizontal axis 87, and this will distort all three beams into a line focus which may be desirable to avoid MoirÚ effects; alternatively they may be smaller in order to distort initially elliptical beams into spot foci. It is not necessary for the edges of both electrodes to be curved, and when the electrodes are of unequal diameters the effective boundary is the radial projection of the inner one on to the outer one, or an imaginary extension of the outer one. The outer electrode may be a wall coating.
