Abstract: ABSTRACT OF THE DISCLOSURE A pulse arc welding machine in which, when any one of the material and diameter of a consumable wire electrode or the shielding gas used is varied, a peak current value and pulse width of a pulse current applied between a consumable wire electrode and a base material being welded as well as a wire feeding speed required for optimum welding conditions are automatically adjusted.  The welding machine includes a consumable wire electrode, a wire feeding unit for the wire electrode, a base current source, and a pulse current source for supplying a pulse current superposed on the base current. A   sensor detects the arc discharge voltage between the consumable electrode and the base material being welded. The quantity of heat applied to the electrode is corrected by comparing an output detection signal produced by the sensor with a preset arc voltage and then producing a pulse width instruction signal in response to the difference signal for setting the pulse width of the pulse current.  When the detected arc voltage is large, the quantity of heat applied to the electrode by the welding  current is decreased and the wire feeding speed is increased, while when the arc voltage is small, the quantity of heat applied to the wire electrode is increased and the wire feeding speed decreased.

Abstract: ABSTRACT       An unsaturated halogenated or non-halogenated polyester resin composition for open lay-up moulding and containing styrene as an agent for cross-linking during curing additionally contains 0.1 to 5 by weight, based on the total weight of the composition, of at least one C18-40.alpha. - olefinecompound which is theoretically capable of taking part in the cross-linking reaction.     When the composition contains a non-halogenated polyester resin, then the .alpha.-olefine compound itself serves to restrict styrene evaporation from the composition.     For halogenated polyester resin compositions the .alpha.-olefine, although not usually by  itself providing such a marked restriction of styrene evaporation, does allow in corporation into the composition of a waxy compound in an amount sufficiently large to achieve the desired styrene evaporation restriction without deterioration of the adhesion properties of the composition during lay-up.

Abstract: Abstract The present invention provides a novel appara-tus and process for generating a vapor spray from a vol-atile fluid.  In the invention, the volatile fluid is heated to a temperature just below its boiling point prior to being discharged from heat exchanger (18, 46). In one embodiment of the apparatus, heat exchanger (46) contains a diffusion plate (48) to ensure that the vola-tile fluid is at the selected temperature when discharged from the heat exchanger.  In this embodiment, the appara-tus further includes a pressure-responsive valve (40) and a bypass line (42) so that a selected pressure is main-tained downstream from pump (34).          The novel process of the present invention in-cludes the step of heating the volatile fluid within heat exchanger (18, 46) to a selected temperature just below its boiling point prior to discharge from the heat exchanger.  In one embodiment, the process further in-cludes the step of impinging the volatile fluid stream as it enters heat exchanger (46) onto diffusion plate (48) so that it is ensured that the volatile fluid is at the selected temperature upon discharge.  In this embodi-ment, passing of the fluid drawn from reservoir (32) is accompanied by modulating the flow of the drawn fluid through bypass line (42) connecting pump (34) and reser-voir (32), whereby a selected pressure is maintained downstream from pump (34).

Abstract: ABSTRACT OF THE DISCLOSURE A loudspeaker telephone system is comprised of a voice switching circuit, hybrid, and power supply circuit.  The voice switching circuit is provided with the comparators for comparing the speech through the main paths with the side tone through the auxiliary paths, the time constant circuit for controlling exponentially a pair of the variable gain amplifiers for making or breaking the sending and receiving signals, and four band pass filters arranged in each input of the comparators for rejecting the indoor noise as well as the line noise coming into the loudspeaker telephone system through the lines. Accordingly, the howling effect between the microphone and the loudspeaker is inappreciable, the transfer from the sending mode to the receiving mode is easily made while maintaining a naturality of the voice. Also, with the con-struction of the impedence matching elements in the conventional hybrid, the hybrid can be used in common either in the present loudspeaker telephone system or in the conventional telephone system.  In the loudspeaker telephone system, the line current is used as a bias voltage by the construction of the power supply circuit, therefore there is no need for providing an additional power supply source.
