Title: Flight simulators
IPC: G09B9/20
Filed: 1971-08-26
Abstract: 1366358 Flight simulator computer SINGER CO 26 Aug 1971 [27 Aug 1970] 40026/71 Heading B7W A flight simulator computer capable of simulating each aircraft of a class having common aerodynamic and physical characteristics comprises circuits implementing electronically the flight and engine equations of one aircraft of the class, the equations being arranged so that those terms which differ substantially between aircraft are expressed as the product of a term and a conversion constant, and selection means to introduce into the circuits one of a plurality of sets of conversion constants, each set comprising the appropriate constants for a further aircraft of the class. Thus for example the acceleration of an aircraft is given by where W g  is the aircraft weight, T n  the total thrust, F x  the total force on the aircraft other than gravity and thrust, i.e. mainly drag, and γ is the flight path elevation angle. For a different aircraft this becomes where K 1  and K 2  are constants. Thus that part of a computer 17 calculating V p  from values of F x , T n , l/Wg and sin γ may be caused to calculate the acceleration of any aircraft for which voltages corresponding to l/K 1  and K 2  can be supplied by means of switch 55 to act as multiplicands in field effect transistors Q71 and Q73. Digital computation may also be used. In this way, using further constants, rotational equations, and equations of angle of attack, side slip, fuel flow rate, turbine exhaust temperature, engine pressure ratio, &c., may be transformed for simulation of different aircraft. Precalculated constants may be used in order to allow an existing simulator designed to represent one aircraft to simulate other aircraft of that class. (For Figure see next page.)

In a thrust reverser for jet propelled aircraft which can alternatively be used as an air brake, each of two double doors arranged symmetrically about the horizontal plane of symmetry of the jet pipe rear fairing has forward parts and rear parts hinged to one another about an axis transverse of the said centre plane, said axes describing circular arcs about fixed pivot points arranged adjacent to and symmetrical of said plane, while the leading edges of the forward parts are pivotally guided on slide booms in straight or slightly curved longitudinal guide tracks, whereby the said double doors can be moved from a fully retracted position flush with the said rear fairing into an intermediate position forming an air brake, and into an end position forming a so-called W-type thrust reverser. the wedge of the W-profile being formed by the trailing edges of the rear parts of the double-doors contacting one another in said centre plane, and the edges at the free ends of the W-profile being spaced apart from the trailing edge of the said rear fairing. A pair of jet pipes are arranged side-by-side in a rear fuselage fairing 33 which terminates in a pair of opposed double folding doors 1, 2 and 1<SP>1</SP>, 2<SP>1</SP> which are arranged symmetrically about the normally horizontal plane containing the axes of the jet pipes. The mechanism, described in detail for the upper doors only, comprises a sliding boom 21 attached to the leading edge of door 1 and provided with rollers 19 to engage a trackway 121 along which it is moved by a jack 16, the boom being locked in its forward full-line position by a locking bolt 14. The doors 1 and 2 are connected by a transverse pivot 3 and the rear end of door 2 is connected to a fixed pivot 22. In operation the jacks 16 are extended to move the doors to the intermediate dotted-line position in which doors 1 project beyond the profile of fairing 33 to act as an air brake, doors 2 being positioned so that their rear edges 12 do not impede the flow of propulsive gases from the jet pipes. The air-braking effect may be supplemented by a flap 24, which may be perforated, fixed to the leading edge of each door 2 and normally housed within the outer profile of door 1. Further extension of jacks 6 moves the doors to the rearmost chain-dotted position in which the edges 12 abut and the doors wholly contain and deflect forwardly the propulsive gases.

Title: Pneumatic tensioning and discharging device for circular knitting machines
IPC: D04B15/92
Filed: 1964-10-07
Abstract: In a circular machine having two co-axial tubes within the needle cylinder, fabric is tensioned during knitting by offlying air suction down the outer tube, and is turned inside-out after press off by suction through the inner tube.  The fabric is received in a displaceable chamber from where it is discharged by a stream of air. The take-up mechanism comprises coaxial tubes (10, 11 Fig. 8, not shown) which may be selectively connected, via a valve (40) Fig. 2 (not shown) to the intake (31) of an air supply means (30).  The fabric is tensioned during knitting by air flow down the outer tube (10), and after pressing off is drawn down the inner tube (11) by the re-directed air flow, and is thus turned inside-out.  The fabric is received in a chamber (45), which may constitute in an alternative embodiment (Fig. 10) the valve (40), and is discharged when the chamber is moved into registry with the air supply outlet (32). Items may be discharged to an inspection station at predetermined intervals. The fabric may be inspected through a port in the outer tube (10), and fabric prematurely pressed off may be ejected from the tube by compressed air.  Severed yarn ends are removed and caught in a trap (103), Fig. 1 (not shown), through a tube (100) connected to the air supply means.

Title: Improvements relating to position detection and control
Inventor: BUTTERFIELD MICHAEL HUGHES
IPC: B65H23/188
Filed: 1959-12-02
Abstract: 976,982. Electric correspondence control systems. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Feb. 28,1961 [Dec. 2, 1959; March 23, 1960], Nos. 40949/59 and 10330/60. Heading G1N. A driven member is speed controlled by a differential device which has two inputs, each proportional to the speed of the member, the arrangement being that when it is desired to apply the control one of the inputs is braked so that the differential device produces a signal increasing or decreasing as the input falls so as to effect the desired control. The invention is described with reference to stopping a piece of strip material 10 passing to an electrolytic bath 15 so that its waste end may be sheared off at 16 and another strip welded on at 17. Each strip has previously been provided with two pairs of marks spaced along the strip, one pair behind the waste edge and the other a further 200 feet beyond that. The roll is then coiled up so that the second pair of marks passes first in the direction of the electrolytic bath. Driven in step with the strip movement are a pair of transmitters 26 of synchro devices 21, 22. These devices are fed from a generator G which also feeds the rotors of synchro-receivers 23, 24,which thus rotate in synchronism with the transmitter rotors. The rotor of synchro 22 rotates ten times as fast as that of synchro 21. In operation, the first pair of marks is detected photo-electrically to operate a relay ER which disconnects the rotor of receiver 23 from the generator G and connects it to output terminals CC which control a Ward-Leonard or amplidyne device to slow the strip feed. At the same time a brake is applied to the rotor 23 so that the degree of slowing varies. When the second pair of marks is detected by a different photo-electric arrangement to energize a relay BR, the rotor of synchro 23 is disconnected from the control terminals and replaced by that of synchro 24 acting as a fine control to stop the strip. Modifications are described in which the receiver rotor is driven by a servo which may be de-energized to brake the receiver rotor. A phase changing synchro may also be inserted to produce a rising or falling control characteristic.
