Title: A method of printing or otherwise mechanically producing composite characters, such as Chinese characters
Inventor: GRIESE EJGIL OTTO KAJ
IPC: G06F3/01
Filed: 1982-10-20
Abstract: A method of printing or otherwise producing a text of composite characters, such as Chinese, Japanese, or Korean characters, is based on determining a number of basic elements from which all of the characters can be composed and giving each of the basic elements a name which can be written using the Roman alphabet so that each character can be identified by keying the names of its composite basic elements in a predetermined order on a conventional keyboard having twenty- six Roman letter keys and a number of punctuation and function keys. The method comprises using such a keyboard as the input to a computer which is arranged to control the operation of a typecase or its equivalent (for example a photo-composing machine, electronic typewriter or word processor, etc.) containing all of the different characters so that the desired character is printed or otherwise produced following selection of the character by the computer in response to the appropriate sequence of basic element names entered on the keyboard. The specification describes the method in relation to the Chinese language which contains about twenty thousand characters, the characters being resolved into about three hundred named basic elements as illustrated in either Figures 2a to 2c or Figures 3a and 3b.

Title: Magnetic collection of particles from a fluid
Inventor: WATSON JAMES HENRY PETER
IPC: B03C1/00
Filed: 1984-01-30
Abstract: A conduit along which a stream of fluid flows has a collector for collecting magnetic or magnetizable particles from the fluid. The collector comprises means 16 for applying a magnetic field M transversely to a magnetic collector strip or preferably an array of transversely spaced strips 18, preferably of paramagnetic material. The strips lie in a plane which is transverse to the streamflow direction A. The magnetic field converges on the strips and the magnetic field gradients around the strips are high. Magnetized particles in the fluid are strongly attracted to the strips. A region of stagnant or quiescent fluid forms downstream of each strip and particles can accumulate in these regions with a reduced likelihood of being removed by the fluid stream. The collector may be incorporated in a removable plug. For indicating the amount of particles collected, electromagnetic radiation is applied to the collector to excite the particles, which emit an odd harmonic of the exciting frequency. <IMAGE>

Title: Cam lock assembly
Inventor: ALSUP JAMES DOUGLAS
IPC: A47C9/02
Filed: 1984-02-14
Abstract: A cam lock assembly. e.g. for interconnecting a support arm with a seat of an operatory stool. A shaft has a first end 40 and a second end 52, each adapted for independent attachment to the support arm. The shaft comprises a portion 41 intermediate said ends the longitudinal axis of said intermediate portion being offset from the longitudinal axis of said ends. A cam 38 is mounted on said intermediate portion 41 and is biased by a spring 37 in a predetermined direction about the shaft towards engagement with the inside surface of a vertical tube fast with the seat. The cam co-operates with that surface of the second member to resist clockwise rotational movement of the support arm relative to the seat when said first end 40 of the shaft is attached to the support arm and counterclockwise rotational movement of the support arm relative to the seat when said second end 52 of the shaft is attached to the support arm. <IMAGE>

Title: Exhaust mixer for bypass gas turbine aeroengines
Inventor: MAGUIRE ADDISON CHARLES
IPC: F02K1/38
Filed: 1984-04-03
Abstract: The exhaust mixer 11 is of the lobed type in which the trailing edges of the confronting sides 23,25 of each lobe 21 are cut back to form notches or scallops 35,37 in the lobe sides 23,25 respectively. To reduce aerodynamic losses and engine length and weight, the final turbine stage within the engine core 3 is without outlet guide vanes so that the turbine exhaust gas stream has a substantial swirl component of velocity. Correction back to an axial direction of mean flow at the downstream end 31 of the exhaust mixer 11 is achieved by making the area of the scallop 37 in one of the sides 25 of each lobe greater than the area of the scallop 35 in the other side 23, the arrangement being such that sufficient of the turbine exhaust stream effuses from the larger scallops 37 in directions contrary to the swirl component of velocity to produce the desired correction. <IMAGE>
