Abstract: A multi-package carrier device having a strip of a relatively high coefficient of friction material along an inner portion of the carrier. A high coefficient of friction, "tactile," material is applied to an encircling aperture style multi-package carrier device made from a relatively low coefficient of friction thermoplastic base material sheet. A strip of the tactile material is applied along one side of the base material of the multi-package carrier. The base material containing the tactile material is then cut into multi-package carriers such that the tactile material traverses a center portion of a container contacting surface of the multi-package carrier. The multi-package carrier is applied to a plurality of containers. After the multi-package carrier is applied to the containers, the tactile material between the rows of containers is in close contact with an upper portion of the container sidewall.

Abstract: A formwork constructed of prefabricated elements, preferably for building a concrete wall. The formwork has two parallel walls that define a space that is filled with concrete laden with water, sand and large aggregates. An inner wall of the formwork has a lattice or perforated structure to filter and pass water and small aggregates from the space that is filled with concrete. An outer wall also has a lattice or perforated structure to filter additional water and smaller aggregates from the space that is filled with concrete. This invention also includes a concrete heating wall that may be constructed from formwork.

Abstract: A device for detecting soil compaction density comprising at least one shell material forming an enclosure, a failure plane disposed within the shell material which causes the shell material to fail at a preset static or dynamic pressure, and a detector, such as an odoriferous chemical enclosed within the enclosure which is released upon failure of the shell material, thereby indicating that the preset static or dynamic pressure has been achieved.

Abstract: A cylindrical cutting element for a cutting machine which includes base ps arranged at a uniform distance from each other. A chisel holder which receives an exchangeable chisel is secured with respect to each base element. The chisel holder has a plug connector which allows the chisel holder to be inserted into a plug receiver of the base element, where it is held by a pressure screw on the base part that grips the plug connector. To relieve the plug connector from the forces acting on the chisel, the base part has a projection which extends in an approximately parallel direction to the running direction of the cutting element and a stop that follows the projection in the running direction and forms an angle therewith. The stop limits the insertion of the chisel holder into the base element and absorbs forces transmitted through the chisel to the chisel holder.

Abstract: A plug-in safety coupling for pressure lines including a coupling socket (1) having a blocking member (3) pivotally mounted therein and a plug (2) insertable therein for pressureless coupling and uncoupling.

The bolt or cam (67) is displaceably guided at the coupling socket (1), and in the blocking position engages into a bore or a recess in the blocking member (3). The blocking member (3) has a through bore extending perpendicularly to its pivotal axis into which an adapter (4) having a through bore, is insertable and fits tightly and sealingly and where an internal surface of the adapter (4) is shaped to receive the plug (2) to be inserted.

Abstract: A process for burning solids on a sliding fire grate system where each of the combustion control criteria are measured and controlled individually for each grate plate comprising the grate system.

Abstract: A process and apparatus for combustion of fuel which results in reduction of nitrogen oxides and carbon monoxides emissions. Fuel and primary air are preferably premixed and introduced into a combustion chamber. Secondary air is introduced through a plurality of secondary air ports which are positioned about a venturi nozzle or flame holder disk mounted with respect to a combustion chamber wall. The secondary air flowing through the secondary air ports forms relatively high velocity and momentum secondary air jets that promote rapid mixing of the fuel and primary air mixture into the secondary air flow, such that a combustion flame is established at a periphery of the secondary air jets.

Abstract: A method and apparatus for introducing a liquid or gaseous treatment medium into a flue gas stream wherein a total adjustment value for controlling the amount of active substance in the treatment medium is generated by an actual value measurement of a flue gas component and a comparison with a set value, and the treatment medium is injected through a plurality of nozzles into the flue gas stream flowing through a flow chamber. The flow chamber is divided into a three-dimensional matrix of partial flow chambers, each of which comprises a nozzle and measuring devices for detecting the temperature and flow speed of the flue gas stream in the partial flow chambers. The active substance is injected with a constant volume flow of treatment medium in an amount determined by calculation of an individual adjustment value of active substance for each nozzle. The total of the individual partial adjustment values does not exceed the total adjustment value of the active substance.
