Title: Probe for Foucault current detector - comprises two coils wound on two small diameter parallel magnetic cores
IPC: G01N27/90
Filed: 1974-02-15
Abstract: Faults of very small dimensions are detected using a Foucault current detector probe during non destructive testing. This is possible using a probe having two magnetic parallel cores of small diameter on which the windings are placed. A probe (5) of small dimensions comprises two windings (10, 12) each wound onto a magnetic core (14, 16) whose axes are parallel. These two windings are connected to an oscillator and analysis unit (18) in order that the oscillator can provide excitation currents for the coils connected as two arms of a bridge. Differential measurements on the bridge give the variations in impedance of these windings due to material changes or faults in the test piece (20).

Title: Auto-productive gasometer making hydrogen as energy source - wind channels in jacket creating pressure differences driving turbo-generator for electrolysis
IPC: F03D9/00
Filed: 1974-11-18
Abstract: An appts. for recovering wind energy incorporates a vessel, subjected to the wind, fitted with passage ways which are subjected to pressure or to depression, and which direct the wind to a turbine. The turbine drives a generator and the current produced is fed to an electrolysis unit where gas e.g. hydrogen is produced. The hydrogen is stored in the vessel and is used as a source of energy. The appts. is entirely automatic. The appts. exploits aerodynamics. The wind ward surfaces are subjected to a steady flow without the stream becoming detached-zones of pressure. The leeward surfaces are subjected to turbulent flow, even in parallel flow-zones of depression. These effects are harmful to the stability of structures and necessitate using resistant materials, the wind energy being annulled without being recovered. The invention exploits these effects by using the energy resulting from the upstream and downstream pressure difference.

Title: Shaving head for an electric razor - has continuous helical blade mounted on belt driven rotating shaft
IPC: B26B19/16
Filed: 1975-03-19
Abstract: The electric razor has a motor (1) with a pulley driving a belt (2) which drives the shaft (3).

There are no parts with reciprocating motion consequently there is no vibration and noise is also reduced. It is thus possible to operate the razor at relatively high speed and provide a very rapid shave.

Title: Mixer for viscous prods. incorporating double-walled compartment - with baffles mixing circulating prod. is easily dismantled for cleaning
IPC: B01F23/47
Filed: 1975-07-15
Abstract: A mixer or homogeniser for viscous prods. incorporates a double-walled compartment, formed by two cylindrical vessels one inside the other, and having an inlet and an outlet. One of the walls is provided with projections. These projections are in parallel rows around the wall and slope in opposite senses in alternate rows. In addition, the projections are staggered in alternate rows. The two walls are in contact with means of heating or cooling. The mixer is a static one, the operation being carried out by the material being pumped through the double-walled chamber. Each projection divides the stream it receives into two streams, so that the circulation takes place in many streams which rejoin and divide again. The means of heating or cooling are fluids which circulate in jackets formed by supplementary walls outside and inside the double-walled compartment. The projections which divide the stream may be replaced by a separate grid inserted between the walls of the double-walled compartment. Partic. used for mixing plastics, glues, paints, thick oils, bitumens, tars and chocolate, and for treatment at high temps. e.g. 250-500 degrees C. The appts. resists high pressures. The movement through the mixing chamber can be quite slow, e.g. 0.1 m./min., good homogeneity being achieved by long residence time.

Title: Damping of unwanted inertial movements of loudspeaker coil - uses development of compensating voltage from magnetoresistance fixed to coil
IPC: H04R3/00
Filed: 1975-08-01
Abstract: The system controls a movable coil (1) placed in a magnetic field as in a loudspeaker onto the winding is fixed a magneto resistance (6) whose ohmic resistance is a function of the ambient magnetic field. The variations of the field enables one to obtain at the resistance terminals a voltage proportion to the coil displacement for control of undesired motion, caused for example by the coils inertia. After amplification (5) the voltage is shaped corrected and then injected into the coil circuit. At rest in the absence of the modulated AC signal, no current is injected. The magneto resistance (6) is connected to a corrector amplifier (7) this amplifier being connected to the terminals of a resistance (8) inserted in the movable winding circuit (4).

Title: Solventless film wire coating process - uses vertical oven through which wires move downwards making several passes (HU281076)
Inventor: LEE JOHN DEREK
IPC: B05C3/15
Filed: 1975-08-20
Abstract: The method is intended for producing solventless and semi-solventless coatings. These coatings have to be applied hot, and the warmth rising from the vertical oven can supply most of the need, if the coating is applied the top of the oven, instead of, in the normal fashion, at the bottom. The wire (1) passes over a roller (2), down past the spray (4) where the hot coating is applied and on down through the oven (5) to a second roller. It returns to the top of th oven for a further coat. When sufficient coats have been applied, it s led away (8) to storage. The oven may well be hotter near the bottom than at the top.

Title: Fused powder coatings applied with specific particle properties - obtd. by adsorbed layers on particles produced before coating process
IPC: B05B5/08
Filed: 1976-09-16
Abstract: A method of producing powdered coatings on a substrate, in which the coating has a fine structure determined by the form of the boundary layers between particles and/or agglomerates of particles in the layer utilises a powdered material in which adsorbates are physically and chemically bonded to the surfaces of the particles before they are applied to the substrate and melted or fused onto its surface. The physical treatment of the coating material which influences the physically bound adsorption only modifies the adsorption coating on the particles to a degree at which a particular state of modification is reached; this state of the adsorption layer on the particles is then maintained until they are applied onto the substrate. Pref. in order to achieve bonding boundary coatings between particles and/or agglomerates of particles, the coating material is dried and the atomised coating material is then maintained dry until it is applied to the substrate. Sintered and similar powdered coatings of a desired fine structure are obtd. without adversely affecting the other coating properties. If necessary, the original physical adsorption coating is removed from the particles by a desorption process and then the required adsorption coating is applied to them. The method can be used for fluidised bed coating, gun coating, etc.
