Abstract: 1300615 Attenuation equalizers; travelling- wave tubes PLESSEY CO Ltd 16 Dec 1970 [9 Jan 1970] 1109/70 Headings H1D and H1W A frequency-dependent attentuation equalizer for a travelling-wave tube amplifier comprises a transmission line having two resistive elements spaced apart along, and transversely intersecting, the transmission line, the resistive elements having substantially no inductance or capacitance at the operating frequencies. The attenuator comprising a coaxial line 6 with disc resistors 10, 12 has a frequency attenuation characteristic which provides a maximum attenuation at a given frequency such that the attenuator may be used to linearize the output signal from the travelling wave tube amplifier which has a high gain near the centre frequency of the operating band. The attenuation characteristic and input voltage standing wave ratio are determined by the resistance of resistors 10, 12 and the characteristic impedance of sections 4 and 8, and of section 6, and the line dimension L determines the bandwidth obtained. In an alternative embodiment the transmission line comprises a strip-line (Figs. 3, 4, not shown) and the resistive elements may be in the form of thin film resistor inserts.

Title: Method of producing a p-n junction in a crystalline semiconductor
IPC: H01L23/051
Filed: 1957-02-25
Abstract: 855,382. Semiconductor devices. SARKES TARZIAN Inc. Feb. 25, 1957 [March 9, 1956], No. 1229/60. Divided out of 855,381. Drawings to Specification. Class 37. A method of producing a PN junction comprises applying to a surface of a mono crystalline body of one conductivity type a dot comprising an activator or the opposite conductivity type, placing a second dot consisting of pure tin on the first dot, heating to a temperature between the melting points of the semiconductor and first dot, and cooling to form the junction on recrystallisation. In one embodiment a first dot of gallium and aluminium is applied to an N type silicon wafer followed by a tin dot. After application of a thin sheet of tin to the opposite face of the wafer the assembly is fired at 950 ‹C. and subsequently cooled. During heating the tin mixes with the aluminium gallium so that the metal solidifying over the initial regrown P type region contains a high proportion of tin the ductility of which reduces the strains occurring at the junction during cooling. The resulting device may be soldered between two metal plates forming electrodes. In an alternative method the assembly is mounted during the firing on a metal electrode so that on cooling it is attached thereto via the tin sheet. In this case the other electrode is welded to the composite dot subsequently by passing a current into it via the electrode.

Abstract: 478,156. Springs. HOWARD, G. P. E. Jan. 16, 1937, No. 1351. [Class 108 (iii)] [Also in Group XXIX] A spring device for loading the diaphragm 1 or like pressure responsive member of an automatic regulating valve 8 comprises one or more thinwalled hollow truncated cones of metal or other suitable material, the stiffness of the device decreasing with increase of deflection. When the initial stress is overcome,the springhas the relatively low stiffness necessary for accurate control over the working range. As shown a single metal cone abuts a plate 5 below the diaphragm 1 and an adjustable sleeve 12 and the control pressure is admitted by a conduit 4. In a modification, two columns each comprising pairs of oppositely placed truncated cones act on a cross-bar connected to the valve spindle. An independently adjustable helical spring acting on the spindle allows the initial stress to be increased without too great a reduction in the initial stiffness of the cone springs.

Abstract: 901,857. Thermionic valves. STANDARD TELEPHONES & CABLES Ltd. Jan. 15, 1959, No. 1479/59. Class 39 (1). A miniature thermionic valve includes an indirectly-heated cathode 6, a control grid 3 and an anode 1, each mounted on a metal disc, the grid and cathode discs 5, 10 being annular while the anode disc 2 forms one end of the envelope. Ceramic collars 11, 12, sealed between adjacent pairs of discs, form the envelope wall and the other end of the envelope is closed by a ceramic rod 13, through which a cathodeheater lead is sealed. This rod is of smaller diameter than the cathode disc so that the outer portion of the latter is available for use as a valve seating, and may also be deformed slightly to adjust the grid-cathode spacing of the assembled valve. In the preferred method of assembly of the valve each electrode is welded or brazed to a metal disc which is brazed to a ceramic member. These sub-assemblies are then brazed together on a jig which includes an apertured base-plate providing a seating for the cathode disc and perpendicular rods which press against the ceramic collars, radial slots being provided in the large grid disc to accommodate these rods. In the grounded grid triode valve shown, the large grid disc acts as a screen between anode and cathode circuits, and may also be used to support the valve annular cap-shaped connectors having serrated edge portions being used for making contact with the anode and cathode. In a screen grid valve according to the invention, flexible leads are wrapped around and secured to the electrode discs so that the valve may be suspended in the apparatus wiring, the electrode discs all being of a diameter slightly less than that of the separating ceramic collars.

A ring 12 is mounted within easing 2 by upstream lugs 38 on the ring engaging radial slots 28 in a fixed disc 30 and by downstream lugs 40 engaging radial slots 34 in an inwardly projecting flange 20 on the casing 2. The ring 12, is of material such as steel or fibre-glass so that in the event of fragments breaking off the rotor the ring can move outwardly by distortion of fracture of the lugs to absorb the fragment energy and prevent penetration of the casing 2. An annular spring 14 retained by a spacer ring 16 maintains concentricity between the casing and ring 12. A shroud ring 22 is similarly mounted by lugs engaging slots 28, 34, an annular spring 24 maintaining concentricity of the shroud. Concentric fragment energy absorption rings 42, 44, similar to ring 12, extend downstream from flange 20, lugs on the rings engaging with alternate slots 34 in the flange not occupied by the lugs 40 of ring 12. At their downstream ends rings 42, 44 are located by lugs 62, 64 respectively engaging slots 60 in a fixed disc 52.

Abstract: 697,745. Separating concrete tiles from their pallets.. EASTWOODS. Ltd. Sept. 14, 1951 [Jan. 19, 1951]. No. 1535/51. Class 87 (ii). A chisel-edged tool 14 engages the joint line between a tile 12 and its pallet 13 on which it has been formed and set, and so separates the tile from the pallet. The tiles and their pallets are travelling on a conveyer in the direction of the arrow A, and the tool reciprocates across the conveyer. As shown there are two tools, one on each side of the conveyer: Each tool is clamped between a plate 15 and block 16 supported on a carriage 17 which slides on guides 25. Each carriage is reciprocated towards and from the conveyer by means of an eccentric 19 and rod 20. The rod 20 acts on the carriage in both directions of motion through springs 22, 23. Toward the end of the inward stroke of the carriage, while the carriage is still moving inwardly by its momentum, the rod 20 begins to retract outwardly, thus compressing spring 23 and giving a quick return to the carriage. The eccentric shafts are driven together, and may be coupled to adjacent shafts of other units.
