Patent EP-0393881-A2 (EP)
Inventor: THOMAS KEITH MARCUS
IPC: G01V1/135
Filed: 1990-04-05
Abstract: An acoustic wave energy generator comprises a body having an internal gas-pressurisable first chamber 1 adjoining a second chamber 2 into which a liquid is introduced to cover a vibratable means 4 which may be a flexible diaphragm and is mounted on the second chamber so as to close an associated opening 5 in the second chamber. After the first chamber 1 is pressurised with a first gas a common closed opening between the chambers is opened to cause communication between the chambers 1,2 to permit a shock wave emanating from the first chamber to impinge on the liquid. As a result, the vibratable means 4 is caused to vibrate so as to produce acoustic wave energy in response to the impingement of the shock wave on the liquid. By using different liquids and/or different heights of liquids in the second chamber the generator may be tuned to provide acoustic wave energy with a relatively narrow chosen frequency range or within a chosen substantially single frequency.

Abstract: The present invention provides a heat generating agent for medical waste sterilization. The agent consisting essentially of at least one compound selected from calcium oxide, calcined dolomite, and magnesium oxide, and at least one compound selected from sulfamic acid, sodium bisulfate, and anhydrous phosphoric acid. The present invention also provides a method for sterilizing medical wastes. The method consists of the steps of subjecting medical waste to exothermic reaction between water and a heat generating agent selected from the group consisting of calcium oxide and calcined dolomite or exothermic reaction between iron powder and oxygen to generate reaction heat and/or alkalinity by the exothermic reaction. The present invention provides an aparatus to be used according to the method mentioned above. The apparatus is constructed essentially of a partition for partitioning the container into the housing for housing medical waste and the exothermic reaction means, contact for contacting the first exothermic material to the second exothermic material to react the first exothermic material with the second exothermic material, and a passage passing through the partition when the first exothermic material reacts with the second exothermic material.

Abstract: Process for treating hydrophobic polymer surfaces to form hydroxyl moieties thereon comprises ozonating the surface of said hydrophobic polymer to form hydroperoxy groups thereon, and then irradiating said ozonated surface with ultraviolet light or exposing to heat to convert the hydroperoxy groups to hydroxyl moieties in the presence of a hydrogen donor. Such hydroxylated surfaces possess hydrophilic properties and can undergo the chemical reactions characteristic for hydroxyl groups.

The joint variation of v₁ and v₂ is also displayed by provision of two univariate graphs that exhibit v₁ and v₂ separately as functions of the third variable v₃, with a suitable cursor or other movable indicator associated with each graph. The joint variation of v₁ and v₂ is also displayed as a numerical table of the values of v₁, v₂ and v₃, with a cursor indicating the current choice of value of the variable v₃. The graph of v₁(v₃) versus v₂(v₃) may be provided with an overlay showing normal and/or abnormal ranges of the coordinate pair (v₁, v₂).

Abstract: A film-pulling apparatus for a packaging machine includes guide plates (21) with arcuate inner surfaces. A cylindrically formed bag-making film material(S) is pullled down inside these guide plates while being adsorbed to their inner surfaces by the negative pressure inside suction vacuum chambers (25) flanking the path of the film material. A pair of pull-down belts (30) is vertically stretched between pulleys adjacent to the path and over the suction vacuum chambers. The belts (30) have many holes such that the negative pressure from the suction vacuum chambers is communicated to the film material through the pull-down belts as the pulleys rotate to pull down the film material. An auxiliary vacuum chamber (38) is connected to the suction vacuum chamber (25) through a normally closed valve such that the vacuum condition in the suction chamber can be quickly restored by opening this valve when an abnormal pressure condition in the suction vacuum chamber is detected. The axes of the pulleys are supported by axle bearings engaging with right-hand and left-hand screw parts of a turnbuckle (46) such that the separation between the belts can be accurately adjusted by rotating the turnbuckle.

Abstract: A process of treating argentiferous alloy variously called "zinc crust" or "silver crust", obtained in the separation of silver from lead, removes sufficient zinc in one apparatus and process step to ensure the product is suitable as feed to cupellation. Suitable feed is defined as material, when partially oxidised in a cupel to remove impurities from silver, results in a litharge that is liquid at typical cupellation temperatures. The process requires that care be taken to avoid excessive oxidation of the crust during its formation. No preliminary step to upgrade the crust is necessary, avoiding the associated expense and effort.

Abstract: An optoelectronic switch device is provided which comprises a first semiconductor layer of a first electroconductive type, a second semiconductor layer of a second electroconductive type having a polarity inverse to that of said first electroconductive type, a semiconductor active layer, a third semiconductor layer of the first electroconductive type, and a fourth semiconductor layer of the second electroconductive type, which are formed on a semiconductor sabstrate in this order. Said second and third layers are larger in forbidden band width than said active layer, said second layer is smaller in forbidden band width than the junction part of said first and second layers, and said third layer is smaller in forbidden band width than the junction part of said third and fourth layers. A high resistance range is formed vertically passing through said active layer so as to surround its luminous range and to have resistance higher than that of the luminous range. By providing the high resistance range as shown above, an ineffective current to be flowed out of the luminous range can be outstandingly reduced, and by setting the forbidden band widths as shown above, carriers and light can be easily confined thereinto. It is preferable that said first and fourth layers include layers serving to act as a reflecting mirror and said active layer is sandwiched by these layers. Laser emission can be made under the turn-on condition.

Abstract: Disclosed is an image processing apparatus in which, when the apparatus has not been not used for a prescribed period of time, control is performed so as to halt feed of current not only to a display unit and fixing heater (3a) but also to other components (3,4) not required to operate when the apparatus is not in use, and in which on/off control of the power supply also can be performed through a more compact and less expensive arrangement. When a manually operated switch (13) is being pressed by an operator, a transistor (10) is turned on via the contacts of the switch (13) so that power from a smoothing unit (9) is applied to a regulator (15). The regulator (15) supplies operating power to a microcomputer (50), which subsequently controls the status of the apparatus power supply depending upon the on/off state of an output port (OP3) of the microcomputer. Supply of driving power to other components of the apparatus is achieved by opening and closing contacts through control of a relay (2-A,2-B) in response to an put from another output port (OP2) of the microcomputer (50).
