Title: Method and apparatus for tracking a helicopter rotor or other rotating mass
Inventor: TRIGG NOEL E
IPC: B64C27/00
Filed: 1984-05-22
Abstract: A helicopter has means for giving a prominent display or graphical representation of the rate of revolution of the rotor or of the value of m/R where m is the number of rotor blades and R is the rotor cyclic time, while it is also possible to display measurements of the vibration amplitude at the frequency  l /R, or m/R against %RRPM. This kind of display has not previously been thought necessary for helicopter operation but has been discovered to be most useful in correcting instrument readings in adjusting helicopter rotors for any lack of balance, and in adjusting balancing weights so that there will be a minimum vibration at the rotor speed at which it is intended to fly the helicopter.

Title: Capacitor-carrying plug for line verification testing
Inventor: GREENLEAF JOHN LIONEL
IPC: H01R13/66
Filed: 1984-09-12
Abstract: A plug (23) for use in line verification testing for cut-over of telecommunications switching apparatus is in the form of a small double-sided printed circuit board (24) having two pairs of opposed lands (25,27 and 26,28) for insertion into the test jack of a main distribution frame. Two capacitors (29,30) are mounted on the board, connected to respective opposed lands. Thus with the plug in use there is no DC connection to the new apparatus but AC line verification testing can be performed, When the new apparatus is ready for cut-over the plugs are connected together in groups by threading respective wires (or cords) through a respective aperture (36) in the board and the groups withdrawn in rapid succession by manually pulling on the wires. <IMAGE>

Title: System for interrogating a passive transponder carrying phase-encoded information
Inventor: NYSEN PAUL ANTON
IPC: H04B1/59
Filed: 1984-10-09
Abstract: A "passive interrogator label system" (PILS) comprises an interrogator for transmitting an interrogation signal, one or more "labels" or passive transponders 20 which produce a reply signal containing coded information in response to the interrogation signal, and a receiver and decoder 26, 28, 32 for receiving the reply signal and decoding the information contained in it. The frequency of the interrogation signal assumes a plurality of frequency values within a prescribed frequency range. The decoder includes a mixer 32 (4 quadrant multiplexer) for mixing together the interrogation and reply signals (or signals derived therefrom) to produce a further signal containing frequencies which are the sum and difference of the interrogation and reply signals. A signal processor 34, 36, 38 responsive to this further signal produced by the mixer, detects at least some of the frequencies contained in this further signal thereby to determine the informational code transmitted by the transponder. <IMAGE>

Title: Metering devices and magnetic cards for use with such devices
Inventor: COMBEN PETER ALAN PAUL
IPC: G06K7/08
Filed: 1985-04-12
Abstract: A metering device, for example a parking meter, is battery (17) operable with a processing and control circuit (16) which switches between a high power and a low power mode in cooperation with a card (C) having two separated magnetic strips (M4, M5) to one side of its magnetic data strip (M1, N1, M2, N2, M3). A magnetic sensor (HS) in front of a shutter (SH) is continuously enabled in the low power mode. When a card (C) is manually inserted and the first magnetic strip (M4) passes the sensor (HS) the circuit (16) temporarily switches to the high power mode to operate the shutter (SH). Only if and when the card (C) is further manually inserted to where the second magnetic strip (M5) passes the sensor (HS), the circuit (16) again switches to the high power mode for the duration of an operation in which the device moves the card and processes its magnetic data.

Inventor: NOWLIN THOMAS E
IPC: C08F10/00
Filed: 1986-11-13
Abstract: A catalyst composition for polymerizing alpha-olefins is prepared by treating a porous carrier (e.g. silica) with a mixture of (a) at least one organo- magnesium composition of the formula n(OR')Mg(OR)m (I> where R and R' are the same or different C1-C12 hydrocarbyl groups, m and n are each 0, 1 or 2, m + n = valence of Mg, and (b) a compound of the formula MXp (II> where M is Si, C, Ge or Sn, X is Cl or Br, and p is the valence of M, in a solvent capable of dissolving the mixture. The product of this step may or may not be dried. Subsequently, it is contacted with a transition metal compound (e.g. TiCl4).
