Abstract: A drum type washing apparatus and a method of processing the wash using the drum type washing apparatus wherein they have a characterizing feature which consists in that the peripheral wall of a rotary drum made of a perforated plate is configured in the form of a wall having a single corrugated portion or a plurality of corrugated portions which do not intersect the direction of centrifugal force generated by rotation of the rotary drum at right angles. Further, they have other characterizing features which consist in that the apparatus is provided with a liquid injecting nozzle and/or a gas blowing nozzle and/or a hot air blowing nozzle for allowing liquid and/or gas and/or hot air to be injected and/or blown into the interior of the rotary drum whereby a period of time required for performing steps of washing, dewatering and drying the wash in the rotary drum can be shortened.

Abstract: A method for spreading thin soft rectangular articles such as cloths, unwoven cloths, paper sheets, plastic sheets, etc. (generally called "rectangular sheets") is disclosed. A part of a first side of a rectangular sheet including one corner of a rectangular sheet is suspended in the air as held nearly horizontally by gripping the corner and another point on the side by grippers which are slidable on a horizontal rail. Accordingly, a second side of the rectangular sheet including the one corner is made to hang down nearly vertically. Then the lowermost end of the second side is gripped by another gripper that is movable vertically along a vertical rail. Except for the one corner, the initially held part of the one side is released, and the rectangular sheet is held with the two adjacent corners at the opposite ends of the second side gripped by two grippers which are movable on the rail.

Abstract: The present invention provides a cylinder head cover for an internal combustion engine having excellent vibration-damping properties which is prepared by molding a composition comprising 75 to 30% by weight, based on the composition, of resin components comprising 50 to 80% by weight of a polyamide resin and 50 to 20% by weight of a modified polyolefin resin modified with an unsaturated acid or its derivative, the total of both the resins being 100% by weight, 15 to 30% by weight of glass fibers based on the composition, and 10 to 40% by weight of mica based on the composition.

Abstract: In a drum type washing and dehydrating machine which is elastically supported, the drum type washing and dehydrating machine according to the present invention comprises a vibration fixing device having a clamping part for fixing or releasing a base on which is installed a treatment drum system, and means for releasing the vibration fixing device from its preceding fixed state, in the washing and dehydrating processes, after the vibrations of the machine passed the vibration resonance point of the system.

Abstract: A method of gripping corners of a strip of cloth, which may be applied to, for example, systems for spreading strips of cloth, including a first step of suspending a rectangular strip of cloth by gripping one corner thereof, a second step of gripping the lowermost corner portion of the strip suspended in the first step, a third step of raising substantially vertically either one of the gripped points of the strip gripped in the first and second steps, a fourth step of applying braking force to the other gripping point in order to apply tension to the strip, and a fifth step of holding substantially horizontally one side of the strip having a corner portion which is adjacent to the gripped points and gripping the corner portion of the strip which is adjacent to the gripped points of the strip gripped in the first and second steps, respectively.

Abstract: A method of gripping corner of a strip of cloth, which may be applied to, for example, systems for spreading strips of cloth, including a first step of suspending a rectangular strip of cloth by gripping one corner thereof, a second step of gripping the lowermost corner portion of the strip suspended in the frist step, a third step of raising substantially vertically either one of the gripped points of the strip gripped in the first and second steps, a fourth step of applying braking force to the other gripped point in order to apply tension to the strip, and a fifth step of holding substantially horizontally one side of the strip having a corner portion which is adjacent to the gripped points, and gripping the corner portion of the strip which is adjacent to the gripped points of the strip gripped in the first and second steps, respectively.

Abstract: An apparatus for automatic identification and couting of a large number of returned or collected used linens at once by recognizing the shapes of markers that are opaque to X-rays and attached thereto. By numerically processing the shadow images of the markers projected onto an X-ray detector, a many kinds of linens can be identified and counted according to classification instantaneously.

Abstract: The invention resides in a compression membrane for wringing liquid out of an object to be compressed, characterized in that its marginal portion whose width is of the order of 15%-35% of the width in the radial direction of the membrane body is made smaller in stretchability than the other portion, whereby no tear of the object to be compressed does not tear during the dehydration thereof.

Abstract: In a conveyor for continuously conveying linens or like materials one by one as gripped at a plurality of points by chucks moving along a rail, a first sensor for detecting passage of the chuck is disposed at a predetermined position along the rail, and two or more second sensors for detecting existence of a linen are disposed at two or more predetermined positions. Means is provided for expanding a distance between adjacent chucks being moved continuously in the proximity of the first sensor. In response to detection signals issued from the sensors, the condition of the chucks gripping the linens can be recognized whether a given chuck is gripping a front corner, a rear corner or a middle point on an upper edge of a linen, it is gripping only one point of a linen, or it is gripping nothing (that is, idle).

Abstract: A device for extracting water from a load of articles which have been washed uses fluid pressure to exert a force on the load. A system controls the fluid pressure such that only low pressure is applied to the load for a predetermined period of time at the beginning of the water extracting operation. Subsequently, the load is subjected to a high pressure exerted by the fluid.
