Title: Method and system for detecting polynitro compounds
IPC: G01N27/64
Filed: 1973-09-14
Abstract: 1400333 Detecting explosives STANFORD RESEARCH INSTITUTE 14 Sept 1973 [14 Sept 1972] 43287/73 Heading G1N A method/system for detecting concentrations of polynitro molecules such as TNT or N-G in air comprises passing a sample through a chamber and mixing it with an ionized gas such as SF 6  so that the TNT or N-G particles become charged and are coarsely sifted with the SF6 into chamber 21 by an electrostatic drift field (from electrodes 17). This provides an amplification (increased concentration) of about 10<SP>8</SP>. A sampling "skimmer" 23 is used conventionally to separate the negative SF6, TNT and N-G ions from the neutral molecules. A low resolution mass spectrometer 24 (Wein or quadrapole filter) separates the lower molecular weight SF 6  ions from the TNT or N-G ions which are deflected on to a target 28 such as an electron multiplier to generate an alarm signal. As an ionizing gas SF 6  is preferred since its electron affinity is greater than most normal atmospheric constituents, but less than TNT or N-G which are easily charged from it. SF6 also has a considerably lower molecular weight than TNT or N-G for final "mass separation".

Abstract: 1363442 Yarn coiling apparatus DEERING MILLIKEN RESEARCH CORP 17 June 1971 [22 June 1970 23 Nov 1970] 43323/73 Divided out of 1363441 Heading D1F A yarn coiling apparatus has a turntable 34 on which is mounted a package base 71 having an upstanding central spring core 72, there being means for advancing the turntable 34 towards yarn delivery means 22, 28 said yarn delivery means having a reference surface 29 against which the top of the core 72 bears at the beginning of a working cycle, and means for moving the turntable 34 away from said yarn delivery means 22, 28 at a rate sufficient to maintain the spacing between the yarn on the base 71 and said delivery means. The reference surface 29 is journalled in the plate 28. The turntable 34 rests on a bracket 39 carried by a double acting cylinder 42 movable along a piston rod 43. The movement of the cylinder 42 is controlled by a chain 45 connected to the cylinder and driving a brake 49. Limit switches 51, 52 control the travel of the cylinder. When the coiling operation is completed an arm 54 is swung through 180 degrees to remove the completed package and replace it with a further turntable 34' on which is an empty package base with an upstanding central spring core. The turntable 34' is then raised by the bracket 39 until the spring core is compressed against the reference surface 29 and a fresh winding operation is commenced. If a yarn breakage occurs the brake 49 is actuated by suitable controls (not shown). This stops the lowering of the turntable until the yarn delivery is resumed. The yarn 11 is fed to the whorl tube 22 by feed rolls 15, 16. The motors that drive (a) the feed rolls 15, 16; (b) the whorl tube 22; and (c) the turntables 34, 34' are connected to a common source of power which generates power of a variable frequency.

Abstract: 976,851. Manipulators. PYE Ltd. (P. H. Stephenson). Nov. 27, 1963 [Nov. 27, 1962; April 24, 1963], Nos. 44744/62 and 16079/63. Heading B4Q. In a master slave manipulator in which the gripper on the slave arm is held open by a spring and is closed by a tension force applied to a tape actuated by a handle on the master arm, the force applied manually may be replaced or supplemented by a force derived from a manually controlled power means, e.g. a pneumatic actuator, whereby a greater force can be exerted by the gripper. The magnitude of the force derived from the power means is independent of the manual force. As shown in Fig. 2 a master arm 2 connected at its upper end (not shown) to a through tube extending through a shielding wall supports a tape 6 on pulleys 7, the lower end of the tape being connected to a handle and the upper end extending over further pulleys along the through tube to the gripper on the slave arm. A pneumatic actuator 8 is connected by a tape 9 to the tape 6 and is controlled by a manually operated switch 12 actuating a solenoid-operated valve 13. The force exerted by the tape 9 on the tape 6 may be adjusted by a regulating valve 11. In a modification the handle control may be arranged so that when more than a predetermined manual pressure is exerted the force derived from the lower means is automatically applied. Further, the force derived from the power means may continue to be applied until the manual pressure is reduced below a predetermined pressure. In a modification (Figs. 4, 5, not shown) the pneumatic actuator 8 is connected to the tape 6 via a Bowden cable.

A free rotor gyro comprises a casing 12 with a support shaft 14 having a longitudinal axis 26, a rotor 16 mounted on a spherical ball bearing for rotation relative to the shaft 14 about a spin axis 28 normally coincident with the axis 26 at a null condition of the gyro, the rotor being electrically driven by a drive 24 having a coil assembly with two separate stacks 92, 94 of core laminations spaced in the direction of the axis 26, this arrangement serving to counteract error torques about axes in quadrature with the axis 26. Each stack of laminations is provided with separate coils 96, 98 and these are connected in parallel to the electrical supply. The arrangement is such that when the rotor is in the null position both core laminations overlap the gyro rotor periphery by the same amount. The supply to the drive 24 is preferably a three phase, variable frequency, variable-voltage supply and the drive 24 provides a corrective torque counteracting any error torques due to windage, rotor suspension and the like, and this will be effective even when the rotor is displaced from its null position. The corrective torque can be varied by adjusting either the voltage or the frequency of the supply. An optical pick-off 20 with a lightsource 80, reflector 76 and receiver 78 is provided as also are torquer coils 86, 88 and others (not shown) disposed on an axis at 90 degrees to the plane of Fig. 1.
