Patent EP-0425765-A1 (EP)
Inventor: GEBHARDT WOLFGANG DR
IPC: G01N29/265
Filed: 1990-07-21
Abstract: An ultrasonic test head (2) having a transmitting ultrasonic transducer and a receiving ultrasonic transducer utilises a wave mode conversion between transverse waves (18) and longitudinal waves (10,20) at a surface crack (3). The test zone has a test-zone centre (24) which has a maximum sensitivity and is situated at a distance from the surface (4) of the test piece and down to which surface cracks are expected. There is a monotonically increasing relationship, between the defect depth of the surface cracks (3) and the echo received from the ultrasonic test head (2), so that it is possible to determine defect depth by evaluating the echo level. <IMAGE>

Abstract: The invention relates to an apparatus for the determination of the alcohol content or calorific value of a mixture containing alcohol and petrol by measuring the capacitance C and the conductance G of the measurement system and the temperature T of the mixture in an electrically conducting housing (2) through which it flows, and evaluating the measurement in a measuring circuit (3). One part of the housing (2) forms a first electrode and a sensor element (1) forms a second electrode of a capacitor. The object of the invention is to provide a vibration-proof and pressure-resistant apparatus. This is achieved by a sensor element (1) which is mounted in an intermediate plate (10) and is partly surrounded by the mixture, and which forms an electrical connection to the measuring circuit (3).

Filed: 1987-05-15
Abstract: The measuring system uses a borehole drilled in the ground up to the base of the selected soil section, within which a given liq. is filled. The loss of liq. is a function of the pressure being measured. The process is repeated with a borehole depth which corresp. to the top of the same soil section and the two characteristic curves obtained are used to evaluate the ground permeability. Pref., the loss of liq. is determined by using a pressurised reservoir coupled to the head of the borehole. @(13pp Dwg.No.1/5)@
Patent EP-0381275-A1 (EP)
Inventor: VAN DEN DOOL FRANS
IPC: H04L12/56
Filed: 1990-01-29
Abstract: The invention provides a method for transmitting, via a transmission medium with a plurality of virtual, asynchronously time-divided transmission channels, a flow of data, and in particular a method for protecting these transmission channels against an exceeding of the maximum cell frequencies, based on the "leaky bucket"-­entrance monitoring method. 
     According to the invention the state of the counter of the relevant channel will be decreased on the arrival of a data cell by a value which is a function of the length of time between the moment of arrival of that data cell and the moment of arrival of a preceding data cell with the same channel indication. The decrease of the state of the counter takes place under the same time regime as the arrival of the data cells. Also the increase of the state of the counter, the comparison of that state of the counter with a threshold value and the switching through or not, dependent on the result of the comparison, of the data cell takes place under the same time regime. Owing to this, the monitoring device can function synchronously with the successively arriving data cells in a completely time-divided way, due to which all the virtual channels can be monitored individually by means of only one such a monitoring device. The value by which the state of the counter is decreased on the arrival of the data cell is preferably the product of a first constant value and said length of time between said two moments of arrival. 
     The invention also comprises a device for carrying out said method and is for that purpose provided with read-out means (1), storage means (3, 5, 7, 9, 12, 14), time indicating means (4), computing means (6, 8, 10, 11, 15), means of comparison (13) and switching means (2).

Abstract: A number of different, efficient treatments of slurries and liquid with gas can be provided. A slurry or liquid (22) is introduced into a first end (11) of a vortex (23). A gas (24) such as a chemically reactive gas -- is introduced from exteriorly of the vortex into contact with the slurry or liquid in the vortex, so that a desired reaction between the slurry or liquid and the gas takes place. The treated slurry or liquid is removed from the second end (20) of the vortex while any residual or carrier gas is removed from the first end of the vortex (thru 14). Gas introduction is preferably accomplished through a porous surface of revolution (e.g. cylindrical or conical) wall (16 ) surrounding the vortex, the gas being in minute bubble form when it enters the slurry or liquid. This has particular applicability in the treatment of paper pulp using an ozone containing gas, or in reacting various liquids in the paper and pulp industry with gas (such as reaction of caustic solutions with chlorine or chlorine dioxide gas), the stripping of a strippable component from a liquid (e.g. stripping black liquor soap from black liquor, using air), or absorbing an absorbable component in a gas into a liquid (such as absorbing ozone, chlorine, or the like in water), or scrubbing furnace flue gases (Figure 1).
