Abstract: A time totaling meter and an unit thereof for internal combustion engines comprising a part of an ignition device to lead ignition pulses toward outside of the ignition device, pulse induction means to electromagnetically induce said ignition pulses, waveform shaping means to shape this electro-magnetically induced pulses, and judging means to determine whether this waveform shaped output pulses are derived from operation of the internal combustion engine or not, and capable of counting and storing total operation time of the internal combustion engine from initial operation thereof to said count memory means based on said output pulses selected by said judging means and displaying this counted operation time on display means.

Abstract: An adsorber comprising zeolite retained on structure of substantially inorganic fibers disposed in the exhaust gas stream of an engine. The invention has particular application to purification of exhaust gas streams of methanol fueled engines in combination with catalytic means for decomposing undesired organic matter from the exhaust gas stream. The adsorber adsorbs organic matter from the exhaust gas at relatively low exhaust gas temperatures at which the catalyst is of reduced effectiveness, and desorbs organic matter at elevated temperatures at which the catalyst is of heightened effectiveness.

Abstract: A receiving part is provided externally of the body of a power tool, having an internal combustion engine provided with an ignition system. A plug is insertable in the receiving and has a portion of the ignition system incorporated in it. The receiving socket and the removable plug are provided respectively with connecting parts whereby, when fitted together, they will be electrically connected with each other, completing the ignition system.

Abstract: The revolutions of a diesel engine are counted by providing vibration detector converting the vibration propagating through the fuel injection pipe into an electric signal; an amplitude sorter for receiving the electric output signal of the detector and providing an output signal when the amplitude becomes larger than a predetermined level; a waveform shaper for receiving the output signal of the sorter and converting respective pulse groups to single pulse outputs. The respective pulses from the sharper are judged to determine whether signal pulse in the present period is within a predetermined allowable range or not, and thereby determining whether respective pulses are "normal" pulses or not. The number of normal pulses per unit time are counted and displayed on a monitor.

Abstract: An engine exhaust gas purifying device, and process, wherein the device provides a catalyst device for treating the exhaust gas, an adsorbing device for adsorbing materials from the exhaust gas and a heat exchanger. The device is configured so that high temperature exhaust gas from the engine passes through a high temperature side of the heat exchanger prior to passing through the adsorbing device. After passing through the adsorbing device, the gas passes through the low temperature side of the heat exchanger and then passes to the catalyst device. In an alternate embodiment of the present invention, the catalyst can be disposed in the low temperature side of the heat exchanger.

Abstract: Disclosed are a heat exchange element obtained by forming a sheet material or honeycomb structure having a shape required for a heat exchange element from an organic filler-filled sheet made from an acid-resistant glass fiber, dipping the formed sheet material or honeycomb structure in a suspension of an inorganic filler, at least a part of which is composed of scaly particles, and fixing the inorganic filler applied by the dipping treatment to the sheet material or honeycomb structure by a binder, and a process for the preparation of this heat exchange element and a heat exchange apparatus comprising this heat exchange element. A high acid resistance and a high gas-intercepting property can be maintained even by using a thin and light sheet material.

Abstract: Confirmation of the existance of the proper operating conditions of a power tool is obtained by providing confirmation sensing means for sensing and confirming inspection and verification of the appropriate condition of each one of a plurality of preset operating conditions by the user, a confirmed state judging means for receiving the output of the completed confirmation sensing means and judging what operating conditions have been completely inspected and verified; a confirmation instructing means for informing the user of those operating conditions yet to be inspected and verified in response to the output of the confirmed state judging means; and, switching means for receiving the output of the confirmed state judging means and thereby allowing energization of the igniting circuit of the engine only after confirmation of all the preset operating conditions are completed and met.

Abstract: Disclosed is a highly heat-resistant disc roll comprising laminated discs, each disc comprising 20 to 90% by weight, based on the total solids of mica particles, 1 to 35% by weight, based on the total solids, of a binder, 5 to 40% weight, based on the total solids, of an inorganic filler and 1 to 30% by weight, based on the total solids, of a reinforcing fiber.

Abstract: This invention relates to a disk roll characterized in that the flaky vermiculite particles obtained by pulverizing the expanded vermiculite, which may be optionally mixed with a fiber material, are dispersed in water and filtered to form a thin sheet as a starting material for disk roll.

Abstract: A neutron protection thermal insulating material is obtained by adding a boron compound and, if necessary, a hydrous compound, to chrysotile asbestos fibers. To form the material, the asbestos is opened with the use of a surface active agent in the presence of water. The boron compound is added and air bubbles are incorporated into the mixture which is then dried, molded and compressed. The resulting product is characterized by a construction wherein the opened asbestos fibers are oriented in substantially parallel relation to each other and in the direction perpendicular to the compression direction and air pockets are flatly arranged between the fibers and substantially parallel thereto to reduce thermal conduction through the material in the direction parallel to the direction of compression.
