Abstract: A roofing shingle is provided for shingling a roof with overlapped shingles, wherein the exposed portion of the shingle is selected to be of a height in the installed condition relative to the overall height of the shingle that enhances material utilization, to be at least approximately 44.4% efficient. This is accomplished by using an exposure height of 8 inches relative to an overall shingle height of 18 inches. The shingles are preferably constructed to have either 3 or 4 tabs, thereby having a ratio of exposure height to tab width of either 0.667 or 0.889, respectively. A larger exposure allows one to obtain 200 shingles for each 300 lineal feet of sheet shingle material, when the shingles have 18 inch overall height, and further allows an overall saving in the number of nails required to install a roof. The invention also contemplates variations in tab width within a given shingle and variations in number of tabs from about one to nine tabs in a given shingle.

Abstract: Parameters which are related to the rate at which particulate matter accumulates and is reburnt, are monitored and the time at which a regeneration is required and/or the length of time a regeneration should be induced, are derived based on the same. The temperature at the inlet and outlet of a trap in which particulate matter is accumulated are monitored and measures such as throttling the induction and exhaust are implemented in addition to energizing a heater disposed immediately upstream of the trap as required in order to elevate the trap temperature and to induce and maintain the reburning during a trap regeneration.The pressure differential across the trap can be used to determine the amount of incombustible matter (ash) which has a accumulated in the trap and to modify the regeneration timing.When the temperature of the exhaust gases cannot be raised sufficiently, a by-pass is opened to attenuate cooling of the trap by the low temperature gases.

Abstract: In a hydraulic drilling machine with a boom, arm and bucket as working parts, one or more of the working parts can be vibrated automatically to perform effective drilling with reduced resistance in various types of operations when the soil changes. Adequate vibration can be automatically generated by setting the working mode (Bo, A, Bu, Sk) and vibration mode (L, M, S) according to the soil or operation form beforehand and by setting the automatic vibration mode. Furthermore, since the control input of the working part lever can be added to the automatic vibration, simple and minute repeated operations, such as pressure-shifting, sifting or drilling conducted while the bucket is vibrated, can be performed readily and uniformly without exhausting the operator, and workability can thus be greatly improved.
