Patent EP-0052908-A3 (EP)
Title: Feeding device for a jet mill
IPC: B02C23/02
Filed: 1981-11-23
Abstract: The present invention is concerned with a device for preliminary crushing of a possibly clogged, material to be ground and for feeding of the said material into a jet mill containing a compressed flow of circulating grinding gas and material, so as to produce ultra-fineground admixtures to be used in industry. In prior art, exclusively ejector-type or injector-type feeder devices were used as feeder devices of jet mills of the said type, in which feeders the shifting of material into the pressurized mill takes place by means of the grinding gas. Besides their high energy consumption, another drawback of these prior-art feeder devices consists thereof that the grinding gas jet of the ejector, consisting of water vapour, sucks considerable quantities of air into the jet mill, along with the material, which causes a heterogeneous grinding result and makes the recovery of heat after the grinding difficult. In order to eliminate these drawbacks, a device in accordance with the above invention has been developed, which comprises a substantially vertical so-called plug pipe, which is at its upper end provided with a feeder funnel and which is at its bottom end, either directly or via an additional pipe, connected to the jet mill above the zone of the grinding gas nozzle. At the upper end of the plug pipe, preferably in its feeder funnel, at least one pushing means is provided which moves back and forth and which both crushes any clogged material and forces the crushed material as a tight plug through the pipe into the jet mill.

Patent EP-0140310-A3 (EP)
Title: Method and device for separating emulsions and/or solids from a suspension of solids and a liquid by means of mechanical flotation
IPC: B01D17/035
Filed: 1984-10-19
Abstract: A process and an apparatus are specified by which emulsions or suspensions of both different and changing composition can be separated in a particularly reliable manner. Proceeding on the principle of turbo-flotation, which is known per se, according to one embodiment, the gas is dispersed in the lower region of the vessel so that it is finely dispersed directly at the point where the emulsion is broken up or the suspension is separated, respectively, mechanically. Furthermore, the emulsion or suspension to be separated is supplied to the vessel close to the surface of the emulsion and the residue is removed at the bottom of the vessel. In this way, in continuous operation, a counter-flow between gas or gas/liquid suspension and emulsion can be achieved, thereby avoiding recontamination and re-emulsification. A strictly separated turbulence zone and a superposed flotation zone are formed. Foam carrying the flotate is formed on the surface. When the vessel is contructed so that it is closed, according to a second embodiment the foam can be forced without any mechanical means to a separating device through the effect of the rising gas, in which reliable separation is possible into solids and waste gases, and also into residual water which may be recycled. Flocculation and/or flotation chemicals can advantageously be supplied to the emulsion or suspension in the vessel in the region of the turbulence zone. In addition to a continuous process, in which several vessels are arranged in series and have a continuous flow running through them, a batch or cyclic process is also possible, in which the emulsion or suspension is left in the vessel until complete separation has taken place, and the separation of other substances may be carried out with the aid of other chemicals and/or of other gases in further vessels or a further separation stage.

Title: Soil cultivating implements
IPC: A01B49/02
Filed: 1985-06-26
Abstract: A soil cultivating implement intended primarily for the production of seed beds comprises a row of power-driven rotary soil working members (3) which row extends substantially horizontally perpendicular to the intended direction of operative travel (A) of the implement and a ground roller (15) which is located to the rear of said row of members 3) with respect to the same direction A, the ground roller (15) being upwardly and downwardly displaceable in bodily level relative to the soil working members (3) by moving supporting arms (14), which carry it, about horizontally aligned pivot pins (23). In order to be able to use inexpensive parts to accomplish a change in the level of the ground roller (15) whilst rendering that operation simple and without requiring any great manual effort, supports (18) project rigidly upwardly and rearwardly from side plates (12) of a hollow frame portion which rotatably supports the soil working members (3) and each support (18) is embraced by the limbs of a narrow forked guide (16) that extends upwardly from a pivotal connection (17) to the corresponding supporting arm (14). Each guide (16) is formed with staggered rows of holes (20) and retaining pins can be entered through appropriate holes (20) beneath the lower edges of the supports (18) to determine the maximum upward pivotal movement of the supporting arms (14) about the aligned pivot pins (13) which is possible. If desired, further retaining pins may be entered through appropriate holes (20) immediately above the upper edges of the support (18). A screen (25) extends throughout the working width of the implement immediately in advance of horizontal carriers (4) of the soil working members (3) at the horizontal level of those carriers and has strip-shaped track-disruption means (26) adjustably secured to it to break up the wheel tracks of a tractor or other vehicle which moves the implement in the direction (A) when it is in use.

Abstract: Self contained radio transmitting state estimator modules are mounted on power conductors on both sides of power transformers in electrical substations and on power conductors at various places along electrical transmission lines. They are electrically isolated from ground and all other conductors. These modules are capable of measuring current, voltage, frequency and power factor (or the fourier components thereof) the temperature of the conductor, and the temperature of the ambient air. The modules transmit these parameters to local receivers. The receivers are connected by an appropriate data transmission link, to a power control center which allows determination of the state of the power system. Appropriate control signals are transmitted back to the electrical switchgear of the system to bring it to the appropriate optimum state. Direct local control may also be effected, for example, the prevention of overloading a transformer. A <<donut>> state estimator module comprises a novel hot stick operated hinge clamp and a novel voltage sensor which measures the current between an isolated capacitor plate and ground. The donut measures the fourier components of voltage and current over a number of cycles and transmites the components to the local receiver. The local receiver derives the desired electrical measurements such as voltage, current, power factor, power, and reactive power and transmits them to local or remote control stations. Up to 15 donut modules may transmit on a single channel to a single local receiver. Each transmits at intervals which are an integral number. The intervals between transmissions of all donuts do not have a common factor and the average interval is the desired transmission rate. Each donut uses the zero crossover of current of its conductor to establish its transmission interval. The system is self-calibrating using known reference signals within the donut module.
