Title: An improved injection laser
IPC: H01S5/30
Filed: 1966-11-09
Abstract: 1,142,516. Semi-conductor lasers. INTERNATIONAL BUSINESS MACHINES CORP. 9 Nov., 1966 [10 Dec., 1965], No. 50091/66. Headings H1C and H1K. In a semi-conductor injection laser in which the length of the junction is greater than its breadth the resonant cavity is formed along the breadth of the junction and the junction is made non-planar. The inclusion of a non-planar junction allows unwanted modes which are established along the length of the junction even though the surfaces 26, 28 along the breadth of the laser are non-reflective to be suppressed. A gallium arsenide PN junction diode has its longer front 22 and rear surfaces made optically flat and parallel to each other and provided with silver reflecting coatings insulated from the diode. End surfaces 26, 28 are made rough so as to absorb light. In the arrangement of Fig. 3 grooves are sawn or etched in the doped gallium arsenide wafer deep enough to interrupt the junction 16 which grooves are filled with absorbing material so that there is no continuous path along the length of the junction for unwanted modes. Alternatively the junction 16 may be prepared in a meandering fashion, Fig. 4, which is accomplished by placing two masking strips of silicon oxide on the top surface of the crystal prior to diffusion of the P-type impurity zinc. These strips tend to impede the diffusion so that the junction is not as deep in the portions of the crystal below the masking strips and has the form shown. The arrangement of Fig. 5 (not shown) has essentially the same junction configuration of Fig. 4 but is prepared by etching the original body of N-type gallium arsenide to provide two depressions before the diffusion operation. In Fig. 6 the irregular junction 16 shown is obtained by orienting the crystal body prior to diffusion so that it has grain boundaries extending perpendicular to the front and rear surfaces of the crystal. In the embodiment of Fig. 7 (not shown) the junction is arcuate in form and is formed by a solution growing technique. The junction may be cylindrical, Fig. 8, and is formed by a solution growth technique.

IPC: H01Q19/30
Filed: 1969-10-14
Abstract: 1,268,121. Aerials. H. W. EHRENSPECK. 14 Oct., 1969, No. 50301/69. Heading H4A. A directional aerial comprises a cavity resonator having two reflectors with an interposed feed element, and one or more wave-guiding structures disposed outside the resonator in the radiation direction. The axis of the resonator coincides with the axis of the guiding structure, or with the axis of symmetry of the structures if there is more than one. As described, a dipole primary element F, Fig. 6, is positioned between a full reflector M 3  and a partial reflector M 4  formed by a combination of three rods R, S, T, and a slow wave endfire structure D, formed by seven directors D 2  to D 8 , is positioned adjacently outside said partial reflector. The space between the two reflectors constitutes a resonant cavity, which may be tuned for optimum performance over a wide band of frequencies by mechanically adjusting the relative positions of said reflectors. The aerial impedance may be matched to that of the feed by varying the spacing of the dipole F from the reflector M 3 . Said reflector is circular, and is provided with a forward-facing rim B. The partial reflector M 4  may also be in the form of a circular plate, but of smaller diameter than the reflector M 3 . The free edge of the rim B may carry a dielectric plate which encloses either the dipole and the partial reflector, or the dipole only (Figs. 3, 4, 5, not shown). In the former case, the partial reflector may be mounted on the dielectric plate, and in the latter case the partial reflector may be carried by rods extending from the rim. A second partial reflector may be provided between the first mentioned partial reflector and the wave guiding structure, in order to increase the bandwidth of the structure (Fig. 2, not shown). In another embodiment, a primary element F, Fig. 7, is a broadband " bow-tie " dipole, a main reflector M 3  is square-shaped with a rim B extending only along the two edges parallel to the dipole F, and a partial reflector M 4  is a small circular disc. Two slow-wave endfire structures D are disposed one above the other, and each comprises a set of directors D 2  ... D 4 , .... Alternatively, the two slowwave endfire structures may be disposed side-by-side (Fig. 9, not shown) or four such structures may be arranged with two side-by-side and the other two one above the other (Fig. 10, not shown). If circularly or elliptically polarized waves are to be received or transmitted a crossed dipole feed means may be provided and four slow wave endfire structures may be symmetrically disposed in relation to the axis of the aerial (Figs. 11, 12, not shown).

Abstract: 1,072,420. Rocket motors. AEROJETGENERAL CORPORATION. Dec. 21, 1964 No. 51814/64. Heading F3A. A rocket motor casing (10) Figs. 1 to 4 (not shown) is made by winding resin-impregnated glass fibres on a mandrel with the fibres lying substantially in the meridional direction, the casing including at least one head portion which is a surface of revolution such that at any point on the surface the radius of curvature in the meridian plane is half the radius of curvature in a plane perpendicular to that plane. This head contour subjects the meridionally wound fibres to little or no hoop stress so that the thickness of the fibre layers can be reduced. The casing (10) comprises two head portions (12) separated by a cylindrical portion (14), one head portion being provided with an apertured boss (25). To construct the casing a mandrel (26) of the required shape is first made, preferably from a liquid soluble material, e.g. salt. Sections of uncured neoprene or other suitable materials are then laid on the mandrel and cured to form a gas-tight liner. The mandrel is then rotated slowly as the resinimpregnated fibres (24) are wound on to it in a substantially meridional direction until the required thickness is obtained. The fibres are then cured before dissolving out the mandrel. Additional hoop wound fibres (28) may be wound on the cylindrical portion.

Abstract: 1311719 Protective arrangements SIEMENS AG 11 Nov 1970 [11 Nov 1969] 53733/70 Heading H2K A fault-detection circuit for use in the protection of an electrical system comprises a threshold device UG1 responsive to undervoltage, a threshold device IG1 responsive to a lower overcurrent, a threshold device IG2 responsive to a higher overcurrent and a logic circuit arranged to provide an output signal when the devices UG1, IG1 respond to a lower overcurrent accompanied by undervoltage and when the means IG2 responds to a higher overcurrent irrespective of the voltage. The devices UG1, IG1, IG2 provide outputs which cease when the specified conditions arise so that a NOR gate N1 or a signal inverter N2 then provides a signal to an "order transmitter" B. The resulting output signal may control either directly or through one or more protective devices, signalling devices and/or circuitbreakers. A relay U with changeover contacts increases the voltage value at which the means UG1 ceases to provide an output when zerosequence currents arise and an overcurrent relay UA disconnects the NOR gate N1 should a short-circuit fault occur in the circuit supplying the undervoltage means UG1. A polyphase system would be protected by a plurality of such fault-detection circuits with a single selecting circuit to select for operation the relay U associated with the phase having the smallest phase voltage and/or the largest phase current. This selecting circuit may operate in response to a quotient or difference measurement. It may comprise a plurality of polarized relays each having a winding carrying a D.C. current proportional to a phase current and a winding carrying a D.C. current proportional to the sum of the phase currents.
