Title: High deflector
IPC: G02B26/02
Filed: 1968-10-08
Abstract: 1,215,209. Light deflector. INTERNATIONAL BUSINESS MACHINES CORP. Oct. 8, 1968 [Nov. 6, 1967], No.47601/68. Heading G2J. A light deflector which can alter the position of a light beam in response to an electrical signal, comprises a right angled prism 10 and a light reflecting plate 18, As shown in Fig. 1, a Piezoelectric element 22 is fixed to the plate 18. By applying a potential difference across the terminals 24 the resulting differential expansion will cause plate 18 to bow (not shown) from the surface 13; therefore when a light beam 14 is sent through the prism it is totally internally reflected at the surface 13 and is eventually focussed at 16 (dotted lines). However when there is no potential difference across the terminals, as shown in Fig. 1, the light beam will pass through the side 13 into the plate 18, and be reflected by reflecting surface 20 to be focussed at 16a, (bold lines). Switching from one state to another can be speeded up by reversing the potential and evacuating the space between the prism and the plate 18. Another embodiment is shown in Fig.4, this can deflect the beam to a number of digitally spaced positions on the line 60-59 depending on which Piezo-electric elements 55 are actuated. The reflecting plates 46, 47, 48, 49, 50, 51, 52, and 54 are paired in equal thickness as shown. Each suceeding pair increases in thickness by multiples of two to ensure equal digital spacing. The energization of each plate is effected alternately, so that as one is actuated to increase the path length the other is actuated to decrease the path length by an equal amount. This makes all the possible paths the same length, and so they all come to focus on the same plane and not in separate planes as in Fig. 1. Fig. 5 shows a further embodiment which is a beam focussing mechanism. The beam can be brought to focus at the point f1 or the point f2 on the same path by actuating both Piezo-electric elements 67b, 68b simultaneously thereby changing the beam path length.

Abstract: 1,204,769. Pipes; pipe couplings. J. H. ANDERSON. 15 Oct., 1968 [16 Oct., 1967], No. 48703/68. Headings F2G and F2P. A submersible pipe 10 adapted to extend vertically in a body of water is constructed of a plurality of pipe sections 12 joined at 14, each pipe section being formed of a plurality of parallel discrete tubes 32, each of said tubes being sealed at its ends against the entry of liquid and to the exterior of adjacent tubes along the length thereof to render the pipe section wall substantially leakproof. The tubes are sealed to each other along their lengths by gaskets 34 of resilient material, e.g. rubber, which are cemented, moulded or clamped between the tubes. In a modification, Fig. 9 (not shown), the gaskets are integrally merged into a liner which protects the tubes from through-flow particles. The ends of adjacent pipe sections are joined by a flanged ring 38 to which double-ended plugs 36 sealing the ends of aligned tube ends are bolted. A gasket is disposed between plugs and rings 14 to give the pipe sections flexibility. In a modification, Figs. 6 and 7 (not shown), the adjacent ends of tubes of adjacent pipe sections are each sealed by a respective plug 41 or 43, the plugs 41 and 43 being joined by a snap ring 47 and the plug 43 having bosses 54 which are bolted to the flanged ring 38. In a further modification, Figs. 8 and 9 (not shown), plugs 56 and 58 of sealing aligned tube ends of adjacent sections are screwed together. The pipe 10 may be about 24 feet in diameter and constructed of 8-inch steel tubes, said pipe being of hundreds or thousands of feet long. The construction of pipe sections gives the pipe 10 when submerged a buoyancy which reduces the tensile stresses in the pipe due to the weight of the pipe.

Abstract: 1441421 Optical weapon sights for aircraft SAAB-SCANTIA 26 Oct 1973 [13 Nov 1972] 50010/73 Heading F3C [Also in Division G3] A cardan suspended mirror 14, for projecting an optical sighting symbol in a semi-reflecting glass 15, is universally movably controlled by four reversible linear electro-dynamic motors 35 acting between a central member connected to the cardan suspension and a bearing frame 8 and situated at points of intersection between axes of the suspension and a circle whose centre is the point of intersection of the axes; an inductive position transducer 46 between the member and the frame detects the deflected position of the mirror to feed a feedback circuit 48, connected to the motors, which receives symbol position information from a computer and gyro circuit 16, 17, 18 to compare the desired and actual mirror positions in order to hold it at the desired position. Opposed pairs of motors 35, each comprising an outer sleeve and a core fixed to the frame 8 and an intermediate sleeve with a winding fixed to the suspension, are fed by information from each gyro 17, 18 respectively to control mirror movement in each of two mutually perpendicular planes, motors 35V, 35M being fed from gyro 17 via the computer 16, a comparator 49, and an amplifier 51. The inductive position transducer 46 comprises a central core and four outer cores all fixed to the frame 8 and having coils 44, 45; a closed alternating magnetic field is produced between these cores and a spherical bottom of the cardan suspension, movement of which for a central position causing flux differences between opposed cores of the movement occurs in that plane therethrough. An oscillator 52 supplies the alternating signal, which emanates from opposed coils in a given plane in signals mutually out of phase, the voltage amplitude between them differing if the mirror is deflected thus producing a summated alternating signal whose phase determines the direction of the deflection. This signal is rectified by a demodulator 53 to produce a positive or negative signal (according to the deflection direction) which is filtered and fed to the comparator 49 for positional error removal. For bomb aiming, the computer 16 and gyros 17, 18 are switched out and static signals are manually applied to the comparator 49 by rheostats 50 for each plane of movement of the mirror.

Abstract: 1,201,428. Electroluminescence. GENERAL ELECTRIC CO. 22 Oct., 1968 [24 Nov., 1967], No. 50128/68. Heading C4S. [Also in Divisions H1 and H5] A SiC electroluminescent PN junction diode comprises a SiC crystal the bulk of which is N-type containing a donor; the crystal has a diffused region next to one surface in which the donor concentration decreases towards the surface and an acceptor concentration which is greater than the donor concentration at the surface decreases inwardly from the surface, the concentrations being such that at the junction the donor and acceptor concentrations have substantial gradients in opposite directions. The diodes are grown by diffusing B and Al into N-doped α-SiC crystals. Concentrations and gradients are specified. Polished crystals 1b separated by porous graphite spacers 15 are placed in a graphite crucible 7 having dense and porous outer and inner walls 12, 13. The space between the walls is filled with a protective charge 14 of Si and C powder mixed with Al and B dopants, the B dopant may be boric acid. The crucible is heated in a graphite resistance furnace (see Division H5) in an argon stream at 1300, 1450 and 1600 C., each for 1 hour, then at the diffusion temperature, preferably 2200 C. At 1300 C. N diffuses out of the crystals, at 1450 C. the protective charge reacts to form SiC containing uniformly distributed B and Al. At 1600 C. further outgassing of the furnace and charge occurs. At 2200 C. the protective charge maintains a vapour pressure in the inner chamber which prevents dissociation of the SiC crytals whilst allowing B and Al to diffuse in and N to diffuse out, the surface concentrations of N, B and Al becoming equal to that in the charge. The charge may be reused and be of SiC initially. The crystals have a P-type layer on both sides, one of which is removed by grinding, then they are cut into square elements. A dispersion of Al in an organic solution containing Si is applied to the P-layer and heated to form a layer of Al-Si eutectic whilst a Au-Ta alloy contact is fused to the N-layer. The P-layer of the element is soldered or cemented using a Au-epoxy resin to a Au-plated metal base-plate of a transistor type header. A gold wire is bonded to the Au-Ta contact, alternatively Fe or NiCr alloy wire is fused to the N-layer. The header is enclosed by a metal cover with a lens or an all glass cap.
