Title: Improvements in or relating to flight simulators
IPC: G09B9/20
Filed: 1959-06-18
Abstract: 928,223. Grounded aircraft trainers. GENERAL PRECISION Inc. June 18, 1959 [June 19, 1958], No. 20991/59. Class 4. A flight simulator computing simulated ambient air temperature, comprises means adjustable to select simulated temperature at a reference altitude to derive a first electrical potential, means adjustable to select simulated temperature lapse rate to derive a second potential which is modified in accordance with simulated altitude to provide a third potential, and means responsive to the first and third potentials to provide an output representing simulated ambient air temperature. In the Figure, the dynamic pressure is computed from q = f(h) V p <SP>2</SP>/2R(T 0  + 273À18 + a h) where f(h) represents variations in ambient pressure with altitude h, V p  is the true airspeed, R is the gas constant, To sea level temperature, a is the lapse rate of temperature with altitude, and the term 273À18 converts degrees centigrade to degrees absolute (Kelvin). Plus and minus V p  signals derived conventionally are applied at terminals 2 and 4, and added over sealed resistors R-2, R-4 in an amplifier U-2, the output energizing a potentiometer R-8 driven by a V p  servo M-2. The resultant signal V p <SP>2</SP>/2 is reversed in polarity by amplifier U-10 and energizes a potentiometer R-14 driven by a pressure altitude servo M-34, and padded so that its wiper derives an output f(h)V p <SP>2</SP>/2, applied over resistor R-48 to amplifier U-42. Ambient temperature is computed by a servo M-20. An instructor's control 16 operates a constantly energized potentiometer R-16 to derive a signal representing sea level temperature To and fed over resistor R-18 to servo M-20. A constant signal fed over resistor R-20 represents the term 273À18. An instructor's control 32 operates a constantly energized potentiometer R-24 to derive a signal representing the temperature lapse rate a, which energizes a potentiometer R-32 driven by the pressure altitude servo M-34 to derive the term a, h, fed over resistor R-22 to servo M-20. The latter also has a balancing feed back input from potentiometer R-38. The servo shaft position thus represents absolute ambient temperature. The shaft drives a feed back potentiometer R-42 of amplifier U-42 to effect division, and the amplifier output is thus f(h) Vp<SP>2</SP>/2 R(T 0  + 273À18 + a, h), the factor R being introduced by sealing. The output energizes a q servo M-54. The pressure altitude may be derived by a conventional altitude computer driving a constantly energized suitably contoured potentiometer providing a pressure altitude (ratio of ambient pressure to sea level pressure) signal.

Patent GB-1013137-A (GB)
Title: Method and apparatus for bending and supporting glass sheets
IPC: C03B23/031
Filed: 1963-05-30
Abstract: In a method of bending glass sheets the sheet is supported along its lower edge, and is engaged along its upper edge by balancing means to maintain the sheet in a substantially vertical position while the sheet is heated to its deformation temperature, the opposite major faces of the sheet are then engaged in pressurized contact between a pair of glass shaping members to bond the sheet, the upper edges of the sheet disengaging from the balancing means when the sheet is in contact with the shaping members, the shaping members are then removed and the upper edge of the glass re-engaged with the balancing means, and the bent sheet is finally cooled.  A glass sheet is supported along its lower edge by a vertically movable expanded mesh support means 178, and is engaged along its upper edge by balancing <PICT:1013137/C1/1> <PICT:1013137/C1/2> means 158, the latter maintaining the sheet in a vertical plane. Pivotal box-like members 190 containing a wheel 196 are vertically aligned below the lower horizontal member 170 thus locating the bottom edge glass support means 178 in its uppermost position. The glass sheet is then engaged along its upper edge by relatively short downwardly extending walls 159 of the balancing means, this latter suspended from a vertically movable bar 156 resting upon stops 152 is in its lowest position.  A pair of glass shaping members 200, 202, Fig. 10, mounted on pistons are brought into pressurized contact with the glass sheet, and simultaneously cams 242 mounted on racks are brought together under a horizontal bar 156 to lift the top edge balancing means out of contact with the sheet, whereupon fingers 244, 246 attached to the shaping members move into contact with face 198 of the box-like members 190 and move them out of vertical alignment thus lowering the bottom support member 176 out of contact with the sheet.  When the shaping is complete (after about 4 seconds) the glass sheet lowers on to the bottom edge support member 178, and the upper vertically movable horizontally disposed member 156 moves downward until it is supported by hooks 162.  In this position only relatively long hairpin balancing members 160 engage the upper surface of the bent sheet. After bending the glass sheet is quenched by blasts of air jets.  It is preferable if when the glass shaping members are in contact with the sheet they have a margin of up to 1 cm. exposed along each edge.  The shaping members also have a greater thermal capacity per unit area than that of air, thus increasing the rate of cooling of the surface in contact with them compared to that of the exposed margin.  The shaping members are usually made of a heavy metal such as cast iron and have their shaping surfaces faced with a thin material, such as fibre glass cloth. Specification 1,013,138 and U.S.A. Specifications 2,263,005 and 2,537,803 are referred to.
