Abstract: A portable movable discharge processing system by short electric arc, including a power supply cooling water tank, a short electric arc cutting power supply, a ring current device a feeding mechanism, a hanging bracket and a pneumatic ring current tool mounted on the hanging bracket, which are successively and cooperatively mounted on a horizontal plane; an air compressor and a sewage pump, which are successively connected to the feeding mechanism; a self-priming pump and a movable short-electric arc cutting device control cabinet, which are successively connected to the air compressor; an anode device which is connected to the movable short-electric arc cutting device control cabinet through an anode cable; a cathode device which is connected to the movable short-electric arc cutting device control cabinet through a cathode cable; and a water pump which is connected to the anode device through a pipeline.

Abstract: A composite casting special-shaped roll is compounded of two parts: an inner layer and an outer layer. The shape of body of the roll is curved surface, and a center hole is arranged for mount the shaft in that central axis of roll. The casting mold is designed into two parts, namely inner cast mold and outer cast mold through the curved surface design and mold design of the roll body. The composite casting special-shaped roll with the wear-proof working layer of the roll body that is resistant to impact, rapid cooling and heating resistance and the high-strength and high-toughness core is prepared by separate casting. It meets the requirements of the service conditions of rolls used by the steel pipe and cold forming sectional steel rolling mill and other equipment, improves the service life of the roll, saves the alloy material and reduces the manufacturing cost.

Abstract: A motorized and manual clutch of curtain track, set on a curtain track, the curtain track is provided with a belt which is driven by motor and carrier hook parts which are used to hang curtain. The motorized and manual clutch is composed of a clutch body module and a clutch bar module, the clutch body module and said clutch bar module are detachably connected. A gap is provided on the belt, the clutch body module is set in the gap, connected with the belt and moved with the belt. The clutch bar module is set under the clutch body module connected with the carrier hook parts and moves the carrier hook parts. The application of the new practical motorized and manual clutch of curtain track solves the operation problem when power cut or breakdown motor or electrical circuit. It further improves the practical value of motorized curtain track.

Abstract: An electromagnetic system is provided to monitor the activity of a ferrous debris detector of the type which uses electric discharges to automatically disintegrate magnetically concentrated accumulations of micron sized wear particles in hydraulic systems. The data provided are used to detect instances of abnormal wear as shown by either an unusually large number of such discharges or an excessive rate of discharge. Where such abnormality occurs the monitor will provide an audiovisual alarm to warn of the problem in time to prevent catastrophic failure of the system.

Abstract: An apparatus for removing entrapped gas and selectively removing and detecting particles above a predetermined size in an oil lubrication system is described. The oil enters tangentially at the top of an outer cylinder and is caused to cyclonically work its way down to the bottom of the cylinder. The oil is then forced to reverse its flow and travel up along an inner cylinder. The centrifugal force fields created by such flow cause entrapped gas to coalesce in the center of the flow pattern from which point it can be vented from the system. It also causes heavier particles, which are used by the apparatus to detect impending failure, to be thrown out of the flow pattern into a detection cavity positioned at the bottom of the outer cylinder at its periphery while lighter particles remain suspended in the fluid. A conventional magnetic sensor is contained within the cavity to capture the separated particles for subsequent removal from the system and signal their presence to the operator of the system.

Abstract: For clamping a hose or flexible pipe on an insert of corresponding cross-sectional shape, there is disclosed a hose clip which is of generally coil spring configuration and which has two mutually engageable hooked end portions each projecting generally outwardly of the coil, the hose clip having, in its relaxed condition, a non-integral number of turns of a characteristic diameter and being constructed such that, on elastically deforming the hose clip (without plastically deforming it) to bring the hooks of the hooked end portions thereof into mutual engagement, the hose clip assumes its clamping position and the configuration of a coil spring having an integral number of turns the diameter of which is smaller than the said characteristic diameter. Preferably, the hose clip is formed of spring steel wire and comprises one complete and one incomplete turn of the wire when the hose clip is in its relaxed condition.
