Abstract: There is disclosed a power supply system for a washing machine which has an automatic door opening/closing apparatus designed for automatically opening or closing a door, a washing machine driving unit for enabling the washing machine to perform the washing operation, and a control component for controlling the operation of the washing machine driving unit.

Abstract: A safety control system and method for a boiling clothes washing machine has a number of paired washing water temperature detecting devices and heater temperature detecting devices, for accurately detecting the actual temperature of wash water so it will have a sufficient boiling effect on clothes to be washed and for preventing a heater from over-heating.

Abstract: An apparatus for cleaning internal combustion engines in which a cleaning fluid is cyclically drawn from a reservoir by a pump, flushed through the block of the internal combustion engine, and returned to the reservoir by the pump, is improved by providing it with a pair of cleaning fluid reservoir tanks. Also, tank selection valves alternatively couple one or the other of the reservoir tanks to the pump, to the exclusion of the other tank. In one application of the improved apparatus one tank can be dedicated for use to clean gasoline powered internal combustion engines to preserve the characteristic color of the cleaning fluid, while the other tank can be utilized to clean diesel powered internal combustion engines. In another application the system is operated through first flushing and soaking periods and through second flushing and soaking periods. A first tank in the pair is used to initially pump and recover cleaning fluid during the first flushing and soaking periods.

Abstract: A pallet cleaner especially suitable for use in cleaning plastic pallets. The cleaner includes a vertically oriented horizontally extending chamber having a vertically oriented entry opening at one end of the chamber and a vertically oriented exit opening at the other end of the chamber. The pallets are loaded on edge into the chamber through the vertically oriented entry opening, moved through the chamber on edge while a heated pressurized fluid is directed against the upper and lower sides of the pallet, and thereafter are moved on edge out of the chamber through the exit opening. The cleaner further includes wheels so that the cleaner is portable and may be rolled to the site of pallets to be cleaned rather than requiring the pallets to be cleaned to be brought to the site of the cleaner.

Abstract: An improved surgical scrub brush for providing an aseptic skin condition for surgeons and other hospital personnel who participate in surgery. The scrub brush provides for the simultaneous and expeditious aseptic cleansing of the digital, inter-digital, and web areas of the hand as well as the forearm, while at the same time reducing or eliminating skin abrasion and trauma brought about by numerous scrubbings. The scrub brush includes a soft cleansing pad having channels that allow for simultaneous use so that the user can select either bristles or the soft cleansing pad to reduce skin trauma. Additionally, the brush includes an attached fingernail cleaner and reservoir for dispensing antiseptic soap or skin conditioners.

Abstract: A brush constructed to minimize hair loss and removal. The brush has flexible bristles tapering from a base diameter of about 0.003 mm to about 0.007 mm. to a working diameter of about 0.001 mm to about 0.004 mm, and to a length of approximately 1.75 inches to 2.25 inches.

Abstract: An apparatus for treating silicon wafers in an acid bath, comprising at least one advantageously quartz tank (1) for containing an acid in which the wafers are immersed and with which electrical resistors (14) are associated for heating the acid, the tank (1) being positioned during use in a usual process bench or wet hood (3). The tank (1) comprises tubular ducts (5), advantageously of quartz, which are closed at one end (6) and positioned transversely in the tank (1), and which open at (7) into one of its sides (8), the tubular ducts (5) being arranged to removably receive the electrical resistors (14), which are removably connected to the process bench.

Abstract: An adjustable agitation system for an automatic washing machine, a drive shaft oscillatable about a first axis and an agitator oscillatable about a second axis. First and second drive members are mounted for oscillation with the drive shaft and agitator and form a plurality of selectively engageable finger and slot arrangements for oscillating the agitator through a selected one of a plurality of arcs in response to oscillation of the drive shaft through a predetermined arc.

Abstract: In washing apparatus for continuously running webs of material which includes at least two drums arranged in a housing one above the other, around which the web of material is looped; at least one slit nozzle arranged beside the upper drum aimed toward the upper drum from the outside and extending over the width of the web of material, by means of which a flat water jet can be directed toward the web of material looped around the drum; and baffles arranged in the housing for conducting away the mass of water flowing down on the web of material after impingement, the web of material covers the upper portion of the lower drum in one looping zone and a baffle is disposed at the height of this zone beside the lower drum in such a manner that the water wave falling down from the point of impingement at the upper drum and impacting on the baffle is conducted toward the web of material in the looping region of the lower drum.

Abstract: A doffing jet for use in jet dyeing machines to plait fabrics being dyed therein. The doffing jet is placed adjacent the area where the fabric discharged from the jet enters the kier of the jet dyeing machine and is operated by having a supply of dyestuff supplied to the jet in an oscillating or pulsating fashion with the periods of liquid flow being with a force sufficient to move the cloth toward the outer wall of the kier.

Abstract: The dyeing apparatus effects a programmed dyeing pattern on the travelling strip. This apparatus includes a housing provided with a through channel for passage of the travelling strip through a treatment station in the housing. Treatment medium such as a dye is delivered to the treatment station via a channel perpendicular to the strip. In addition, compressed air is delivered to the treatment station via a funnel-shaped channel downstream of the station to remove excess dye from the yarn and to obtain a clean well-defined dyed area on the strip. A similar funnel-shaped channel upstream of the treatment station serves to seal the elongated channel against the treatment medium. Also, an exhaust channel is provided to remove excess treatment medium and air.
