Title: Mixer for rubber or plastics material
Inventor: ELLWOOD HENRY
IPC: B29B7/18
Filed: 1985-04-09
Abstract: The mixer comprises a mixing chamber (12) consisting of two intersecting parallel cylindrical portions (14, 16) in which two rotors (18, 20) are mounted for rotation about an axis A coaxial with the cylindrical portion (14, 16) in which the rotor is mounted. The rotors (18, 20) rotate in opposite directions in synchronism, at the same speed. Each rotor (18, 20) is of substantially circular cross-section at any section along its length, with its centre of cross-section C eccentric relative to the axis A of rotation, and may be cylindrical or helical (see Fig. 2) in configuration. The construction and arrangement of the rotors (10, 20) is such that the gap between them fluctuates to draw in material. The dimensions of the mixer are selected to obtain satisfactory performance: preferably the gap (X) between the rotors (18, 20) is at least twice the minimum distance (Y) between each rotor (18, 20) and the adjacent surface of the chamber 12. This construction may be applied to either batch mixers or continuous mixers and affords a more efficient mixing action than many heretofore known mixers. <IMAGE>

Filed: 1985-11-26
Abstract: Particles in a fluid sample are passed into a flow chamber 12, which has an inlet 20 and an outlet 22 and a passageway 24 having a cross-sectional area which may decrease substantially as the passageway extends from the inlet to a constriction 21, the cross-sectional area thereafter increasing from the constriction 21 to an imaging area 14. The thickness of the passage 24 in a direction which is parallel to the direction in which a microscope 16 is directed, may decrease substantially from the inlet 20 to the constriction 21. From the constriction 21, however, the thickness remains a constant T. The fluid sample is introduced into the flow chamber 12 at a distance L sufficiently far away from the imaging area 14 to be flowing in a laminar stream having a constant velocity profile at the imaging area 14. The working distance Wd of the microscope lens 30 is greater than one-half the outer thickness D of the flow chamber 12 at the imaging area 14. The focal depth Fd of the lens 30 is much less than the thickness D. The flow rates of the fluid sample and the sheath fluid are such that the fluid sample has a thickness t at the imaging area 14 which is less than or comparable to the focal depth Fd of the lens 30. <IMAGE>

Title: Minefield clearing systems
Inventor: PEARCE JOHN ROBERT
IPC: F41H11/14
Filed: 1986-12-30
Abstract: A minefield breaching system is provided in which flexible tubing that is initially reeled on a reel or bobbin 12 is inflated by means of gases that form an explosive mixture and thereby is unreeled and extended to deploy it across a minefield. The reel or bobbin can also be inflatable, for example by means of air, enabling the tubing and bobbin to be stored, when uninflated, as a flat pack. If the bobbin of the pack is inflated and the end of the tubing is connected by separate supply pipes to, for example, separate gas cylinders 15 containing two gases that together form an explosive mixture, admitting the gases to the tubing will inflate the tubing and thereby propel the bobbin away across a minefield, more or less directionally in a straight line, after which the explosive hose so deployed can be detonated. A flash back trap 17 between the gas supply pipes and the inflatable tubing will protect the inflating apparatus and personnel in the event of inadvertent pre-detonation. <IMAGE>
