Abstract: U A compressor air bleed override control system (24) is provided to bleed interstage air from the compressor of an aircraft turbine engine under the conditions during which a compressor instability, such as surge, is likely to occur. The override system includes an override valve control (30,36) that is in communication with an altitude sensor (26) to make the system operative above a preselected pressure altitude, but inoperative below the selected pressure attitude. The altitude sensor (26) is in communication with the engine fuel control power lever (38), which is an indirect sensor of compressor speed, such that at speeds corresponding to a slow deceleration from a sufficiently high attitude, the compressor bleed valve (32) will rapidly open. Another system (50) measures the rate of movement of the power lever (38) so that small but sufficiently rapid movements of the power lever (38), which are sustained for a selected period of time, will also cause the compressor bleed valve (32) to open quickly. The period of time during which the bleed valve (32) remains open is a function of the rate of movement of the power lever (38). Sensor (50) is connected to rate detector/time delay device (54) which controls the opening and closing of bleed valve (32), altitude sensor (26) making or breaking the control circuit at a particular altitude.

Abstract: @ A rotation sensor includes circuitry for sensing both small units of rotation of a rotating body relative to a stationary body and a predetermined angular orientation of the former to the latter, and is designed to prevent electromagnetic interference between the rotation sensor circuitry (FG) and angular position sensor circuitry (PG). The FG circuit defines a full annular ring about the axis of the rotating body whereas the PG circuit covers a relatively narrow annular sector. The FG and PG circuits lie at different radial positions and do not overlap radially. Corresponding PG and FG magnetic rings fixed to the stationary body opposite the PG and FG circuits consist of annular sectors magnetized to alternating polarities. The symmetrical spacing of the FG magnetic sectors matches the angular spacing of FG circuit elements oriented perpendicular to the magnetic flux generated by adjoining magnetic sectors. The PG magnetic sectors match both the spacing and the total angular extent of the PG circuit. As the PG and FG circuits rotate, the corresponding magnetic sectors induce electric fields, resulting in the desired sensor signals. The PG and FG circuits are connected in parallel to a common electrical terminal. Connections from opposite ends of the FG circuit to the common terminal and to the FG output terminal may be curved so as to maximize their length in the magnetic flux region while minimizing their obliquity to the magnetic flux lines.

Filed: 1985-02-21
Abstract: Peroxide-curable fluorocarbon elastomers having interpolymerized units derived from a cure site monomer containing bromine or iodine. The fluorocarbon elastomer gums are prepared by copolymerizing with the principal monomers normally used in preparing fluorocarbon elastomers, e.g. vinylidene fluoride, hexafluoropropene, and (optionally) tetrafluoroethylene, a small amount of a novel cure site monomer which is a vinyl ether in which at least one of the two vinylic (or double-bonded) carbon atoms thereof is bonded to at least one bromine or iodine atom, e.g. CF a CH 2 0CF=CFBr. The cured fluorocarbon elastomers of this invention have useful properties normally associated with fluorocarbon elastomers, such as acid resistance, thermal stability, and high tensile strength. These properties of shaped articles made from these fluorocarbon elastomers are not adversely affected upon exposure to high temperatures for extended periods.

Abstract: @ Clamp member 52 shown in the clamping position can be lifted by piston 47 and swung by cooperation of pin 55 with a helical upper portion of groove 54 when rod 37 is moved downwards by piston 40. The workpiece to be clamped is then placed in position and when the piston 40 rises under the pressure of spring 43 the clamp member 52 is swung over the workpiece and then lowered into clamping position by resilient sleeve 48 acting as a clamping spring. 
     Operating pressure is applied to port 59 and its flow to the cylinders 23 and 25 is controlled by one-way check valves allowing flow into cylinder 23 and out of cylinder 25 and a sequence valve which opens to admit pressure to cylinder 25 after the piston 47 has engaged stop 29. Escape of pressure from cylinder 23 is allowed when piston 40 lifts both check valves.

Abstract: An adjustable shoulder anchorage assembly for a vehicle safety belt. compnses a vertically extending track (10) mounted on the interior of a vehicle body above the level of the shoulders of an occupant of an adjacent seat, and a traveler (22) mounted on the track (10). A guide member (2 4 ) is secured to the traveller (22) and has a slot for receiving the strap of a safety belt. A latch member (28) is movable transversely of the track (10) between an engaged position in which a latching formation thereon is in engagement with one of a series of complementary formations (12) on the track (10) so as to inhibit movement of the traveller (22) along the track (10) and a release position in which the latching formation is disengaged from the track (10). A cam follower (34). on manual release means (38). is operative to engage in a slot (36) on the latch member (28) so as to move the latch member (28) between its engaged and its release positions in response to movement of the manual release means (38), and resilient means (42) are operative to bias the first cam formation (34) into a position in which the latch member (28) is in its engaged position. The part of slot (36) in which the cam follower (34) engages when the latch member (28) is in its engaged position is onented perpendicular to the direction of movement of the latch member (28) between its engaged position and its release position. Thus, application of a force to the latch member (28) in a direction tending to move it towards its release position does not cause the movement of the cam follower (34) necessary to permit such movement of the latch member (28).

Abstract: A method and apparatus for noise suppression for speech recognition systems which employs the principle of a least mean square estimation which is implemented with conditional expected values. Essentially, according to this method, one computes a series of optimal estimators which estimators and their variances are then employed to implement a noise immune metric. This noise immune metric enables the system to substitute a noisy distance with an expected value which value is calculated according to combined speech and noise data which occurs in the bandpass filter domain. Thus the system can be used with any set of speech parameters and is relatively independent of a specific speech recognition apparatus structure.

Abstract: A process for preparing pyromellitic dianhydride by dehydration of pyromellitic acid is disclosed. The dehydration is conducted in solid state by indirect heating. The characteristic feature of the process is that when most of the pyromellitic acid was converted to the dianhydride, the remaining pyromellitic acid is dehydrated while regulating the temperature of the heating medium between 200 °C and 235 °C. By this process, pyromellitic dianhydride with excellent quality, good color and free flowing property can be obtained easily, smoothly, and rapidly. A very simple apparatus can be used in the process and the apparatus can be constructed from cheap materials.

Abstract: A drawing instrument incorporates two substantially planar members (1, 2) each formed with a straight guide edge (3, 4) and means connecting the members to permit them to rotate relatively to one another in parallel planes to define a particular angle between the guide edges with no part of each member projecting beyond any part of the guide edge presented by that member. The two planar members (1, 2) are formed with curved channels (17,18) and a curved connecting piece (14) is in permanent sliding and interlocking engagement with the channels (17,18) in said two members (1, 2). The construction provides that there is no obstruction between the guide edges (3,4) along their entire length irrespective of their immediate relative angular positions thus making it possible to draw angles without interruption from the origin to the ends of the guide edges.
