Title: Heating to detoxify solid earthen material having contaminants
Inventor: HEATH WILLIAM O
IPC: B09C1/06
Filed: 1992-11-12
Abstract: The present invention includes a method of treating solid earthen material having volatile, semi-volatile, and non-volatile contaminants. Six electrodes are inserted into a region of earthen material to be treated in a substantially equilateral hexagonal arrangement. Six phases of voltages are applied to corresponding electrodes.  The voltages are adjusted within a first range of voltages to create multiple current paths between pairs of the electrodes. The current paths are evenly distributed throughout the region defined by the electrodes and therefore uniformly heat the region. The region of earthen material is heated to a temperature sufficient to substantially remove volatile and semi-volatile contaminants by promoting microbial action. This temperature is less than a melting temperature of the earthen material.

Abstract: The appts. for amplifying an optical input signal includes an amplifier comprising a first input for receiving the optical input signal, and an output for providing an amplified optical output signal. An optical fibre is coupled between the first input and the output, and a pump device provides and couples an amplification optical signal to the optical fibre. A second input receives an amplification control signal, and an electrical output provides a signal indicative of the signal provided by the pump. The amplified optical output signal changes w.r.t. the optical input signal and the amplification control signal. Control circuitry receives the electrical signal, produces the amplification control signal, which is limited to prevent the amplification optical signal from exceeding a fixed threshold value if the electrical signal indicative of amplification optical reaches a predetermined value and regardless of a decrease in the optical input signal during the first instance.

Inventor: BAUER FRANZ
IPC: H02P21/22
Filed: 1994-07-11
Abstract: Abstract of the Invention The present invention provides a current regulating method and associated apparatus for a voltage-injecting converter, wherein a flux-producing current component and a torque-producing current component of an actual current vector are regulated to corresponding components of a required current vector, whereby a precontrol variable is superposed on each controller manipulated variable. According to the invention, the torque-producing controller manipulated variable acts on the flux-producing controller manipulated variable with delay as a fashion of a frequency variable, thereby providing a current regulating method which combines the advantages of two-component current regulation and active current regulation. This dual-action current regulation advantageously operates without requiring a structural switch between the two forms of current regulation.

Title: Optical Radiation Devices
Inventor: WOOD DAVID C
IPC: H04B10/112
Filed: 1993-07-28
Abstract: A device, particularly an antenna device, for emitting a beam of optical radiation to irradiate a remote target area. The device includes an optical source (10) having a limited wavelength band, and a hologram pattern (14) positioned in the path of a light beam originating from the source, the pattern being selected to produce a composite beam (20) having a predetermined shape or far field pattern conforming to the target area and/or a predetermined distribution of light intensity in the target area. Where the optical source is a point source, the hologram pattern (10) selectively retards the phase of respective components of the incident wavefront to produce a composite beam having a far field pattern that precludes focusing of the beam into a single small spot. The device has particular application in a telecommunication system wherein a data signal is transmitted through free space by an optical beam, at least one characteristic of the beam being controlled by the hologram pattern in the path of the beam.

Title: A floating modular system to support oil absorbent booms that provide continuous protection for enclosed or semi-enclosed water bodies from floating hydrocarbons
Inventor: DOUNAS CONSTANTINOS
IPC: E02B15/06
Filed: 1994-06-08
Abstract: A floating modular system to support oil absorbent booms that provide continuous protection for enclosed or semi-enclosed water bodies from floating hydrocarbons. The invention refers to an anchored stable modular system, consisting of floats (3) hydrodynamic in shape to which are attached, by means of joints, oil absorbent booms (2). Tie-rods (6) connect the floats (3) to each other.  The floating system allows the continuous use in the field of booms with absorbent material that selectively absorb oil from the surface of the water and may be applied in areas where surface drift current causes its perpendicular positioning and consequently that of the attached to it oil absorbent booms (2) against the direction of the current. This is due to the hydrodynamic shape of the distal floats (3). Generally, the special hydrodynamic features of the system allow it to use water circulation and finally to play the part of a stationary vacuum cleaner continuously absorbing oil from the surface of the water. The invention can be used for the continuous environmental protection of ports, lakes, marinas, etc.

IPC: H01R4/24
Filed: 1993-03-08
Abstract: An insulation displacement contact for communication and data transmission has two separated contact legs connected at one end thereof to define a contact slot therebetween, and is fittable into an existing groove extending obliquely across a channel of a housing for receiving wire extending in the channel. The contact allows proper contact with wire having a rigidity lower than 0.4 mm diameter copper wire, and fits within the groove without compromising its rigidity. This is achieved by having a contact portion of each of the contact legs angled in the area of the contact slot such that the contact portions extend outwardly in opposite directions. The contact portions may be bent to the outward positions, may be displaced parallel to each other, and may have cutout sections positioned diagonally-opposite to each other on the contact slot.

IPC: B28B7/22
Filed: 1995-08-03
Abstract: Sheet steel pan forms bent or rollformed to specific "universal" profiles allow the manufacture of concrete tread filled steel stairs or precast concrete stairs.  The profiles adjust against each other under the specific angle of 26.565° and thereby, used in series, create stairways of various rise and run relations, maintaing the same profile at all times, satisfying requirements of all building codes and follow the measure of the human step on an incline. These "universal" profiles are designed to standardize stair construction, save labor and material and produce stairs more economically than conventional methods employed in today's construction industry.

Title: Process for burning solids with a sliding firebar system
Inventor: KEMTER ANDREAS
IPC: F23G5/50
Filed: 1995-02-06
Abstract: The process is applied to a sliding firebar system consisting of separate firebar stages through each of which separately flows a coolant and half of which are individually movable. The fluid cooling makes it possible to design each single firebar stage to be individually movable and also to operate individually at determined places directly on the hearth with primary air.  This provides new control facilities. Thus the following operations are individually controlled and operated without necessarily being interdependent:  cooling the firebar, local and timed primary air supply, local and timed stoking movements of the firebar and local and timed transport movements of the firebar and timed loading movements. The guide parameters for control are at least the coolant temperatures (T1, T2) of the individual firebar stages.
