Abstract: The pneumatic impact tool comprises a body of a pneumatic motor which body is separated from a body-casing (4) of the impact tool by means of a vibro-isolating system, an air feeder system, a noise suppressor having a double-­chamber, and a working tool (1) slidably connected with a tool sleeve (3). According to the invention the working tool (1) has a flange protecting it from falling down during operation and resting, when said impact tool is being pressed down, on a thrust ring (2) which is mounted on a barrel seat. One of the chambers of the noise suppressor consists of a conic sleeve (34) pushed on the body-casing (4) such that it can rotate around its axis, and is connected with the other chamber defined by a space between the body-casing (4) and the body of the pneumatic motor, by means of orifices (35) forming an acute angle with the main symmetry axis of the impact tool and extending tangentially to the plane of the ca­sing of the pneumatic motor. The body of the pneumatic motor is connected with a vibro-isolator having a con­stant interaction force by means of vibro-isolating spa­cers (14) and releasable fasteners (16). Between the body-­casing (4) and a grip (23) an additional vibro-isolation is provided consisting of a sleeve (25) mounted between a pipe (24) of the feeder and a barrel head (31) and of an elastic layer (38). A space in front of the pipe (24) of the feeder in the sleeve (25) is connected with the first chamber (33) of an air decompressor by means of air passages (32).

Abstract: A gas power burner having a burner tube (16) closed at one end and a venturi tube (100) disposed within the burner tube with the mouth portion of the venturi tube disposed toward the closed end of the burner tube. The burner tube is provided with an air aperture (118) in a side thereof at a position along the burner tube intermediate the mouth portion and the burner head portion of the venturi tube. A blower (86) blows air into the air aperture of the burner tube where the air divides into a first pathway traveling toward the closed end of the burner tube and into the mouth of the venturi tube and also traveling in a second pathway toward the open end of the burner tube. The air traveling in the primary and secondary pathways provides combustion air for a flame burning at a burner head portion of the venturi located within the outer burner tube. A gas orifice (116) communicates combustible gas with the mouth portion of the venturi tube and meters and directs gas to the mouth portion for mixing with combustion air from the primary pathway.

Abstract: An operation frame (26) with two flanges (29, 30) and a drive frame (27) with a single flange (33) disposed between the two flanges (29, 30) are provided for forth and back movement, relative to a base frame (20), guided by a guide bar (24). Two coil spring elements (36, 37) are passed through by the guide bar (24) and are interposed between adjacent two of the flanges (29, 33; 30, 33). When the drive frame (27) is transferred to be deviated relative to the operation frame (26) held at a first operation point, one of the spring elements (36, 37) is compressed and the other (37, 36) tensioned. When the drive frame (27) is transferred to a prescribed position, the holding action on the operation frame (26) is released by a release piece (49) secured on the drive frame (27) and the operation frame (26) is swiftly transferred to a second position by the biasing forces stored in the spring elements (36, 37), operating a switch (5) in an on-load tap changer. If the drive frame (27) is actuated in the reverse direction on the next occasion, the operation frame (26) is transferred from the second to the first operation point similarly by the biasing forces stored in the spring elements (36, 37).

Abstract: An apparatus bushing (26) is fixed to a support wall or the wall of the apparatus housing and is electric­ally coupled to the apparatus within. A high voltage cable is fixed to the single leg of a 600-Amp "T" connector (50) and is supported only by a bracket (74) extending from said apparatus bushing (26) to one (56) of the "T" legs. A removable pin-and-socket applied link member (150) selectively couples the remaining "T" leg (54) to the apparatus bushing (26) whereby power passes between the apparatus and high voltage cable only when said link (150) is present and isolates said cable and apparatus when it is absent. 
     A novel operating assembly (134) assures proper contact between the link sockets and the pins of the apparatus bushing extender and the 600-Amp "T" connector (50) and can be arranged to positively separate the link assembly. The operating assembly (134) can also be used to install and remove a cap assembly when the electrical link (150) is not in place.

Abstract: A clock jitter suppressing circuit includes a control circuit, a delay circuit, and a selection circuit. The delay circuit sequentially delays a clock signal at time intervals sufficiently shorter than the period of the clock signal. The selection circuit selects and outputs one of delay outputs from the delay circuit which is determined in accordance with a selection signal. The control circuit generates a selection signal for selecting a predetermined delay output when no jitter is caused in the clock signal. Every time jitter is caused in the clock signal, the control circuit generates a selection signal for selecting a delay output which is shifted by an amount corresponding to the phase amount of the jitter in a direction to cancel a polarity of the jitter.
