Title: Chopper system for continuous beams of charged particles - eg. protons, electrons or ions
IPC: G21K1/08
Filed: 1973-10-19
Abstract: In a system for chopping a continuous beam of charged particles e.g. ions, protons or electrons of the known type having a source of charged particles, a first particle speed modulator, means for deflecting trajectories of the particles a chopper diaphragm for the continuous beam, consisting of a plate with an orifice therein, (a) the deflecting means comprise an achromatic magnetic deflection system deflecting the trajectory of particles through an angle more esp. 360 degrees, along an arc of a circle and having a plane of symmetry to the plane of the trajectories; (b) the particle trajectories of the same energy intersect at a point in the plane of symmetry but only those of predetermined energy traverse the orifice in the diaphragm; (c) a second particle speed modulator for modulating the speed of particles leaving the deflection system is provided at the outlet of this system on the trajectory of the chopped beam so as to obtain a constant current density in the body of each section of the chopped beam. The transverse emission of the beam is preserved, the density in the chopped sections is substantially constant and since the repetitive frequency of these sections is twice the frequency of the electromagnetic field of the first and second modulators, distortions due to the sinusoidal character of the first particle speed modulated signal are very considerably reduced.

Title: Mineral ore grading system - measures eelectrical resistance of each particles as it falls freely
IPC: B03B13/04
Filed: 1973-11-22
Abstract: The system is for use with ore which is conductive to electricity and whose grain size is between two known limits, and separates the particles with insufficient metal content. The value of the individual resistance of each particle is measured as it falls, and the particle trajectory is varied dependent on whether or not the value corresponds to requirements.

Title: Precision-controlled hot drinks maker with infusion means - has weight loaded piston in heating chamber to transfer hot water in infuser
IPC: A47J31/057
Filed: 1974-04-12
Abstract: The hot drink maker which is designed to prepare coffee, tea or cocoa etc. comprises a heat chamber in which the water is heated and an infusion chamber in which the coffee etc. is placed.

Title: Vortex mixer for flowing media - having similar densities with a swirl being imparted to one or both of the flows
IPC: B01F5/00
Filed: 1975-08-08
Abstract: Process for mixing >=2 media in the same phase and of similar density imparts a vortaxial motion to >=1 of the media and mixes in the second, with or without similar swirl. The mixing occurs by using velocity sectors in approx. the same plane. A drop in potential similar to a vortex occurs. It can take place in a cyclone or vessel with approx. tangential entry and without any inserts, esp. mixing baffles. The chamber can be a rotational body with rectangular, trapezium shaped, elliptical or circular vortex generators. The process is of use for mixing two flowing media in the approx. the same density and of the same phase. The use of static mixers is known and generally these employ either changes in cross section to include mixing or have baffles or other inserts to induce the mixing. The first type have long residence times while the second type suffer from fouling problems. The device claimed improves on these, giving also moderate energy consumption and simplicity of cleaning. There is very little variation across the outlet in the quality of mixing.
