Abstract: An apparatus and process of filtering fluids, such as white water is provided for use in the place of an existing save-all device or downstream of an existing save-all device at a paper-making mill. The white water having contaminants in a suspended state is introduced into the filtration vessel and is withdrawn from the interior of the filter element positioned within the filtration vessel. To clean the filter element from the cake which has built up on the exterior surface of the filter element, a backflushing shock is applied to the interior of the filter element, forcing all cake settled on the exterior to be dislodged, thereby cleaning the filter element. The backflushing shock is delivered from a backflushing reservoir wherein the backflushing fluid is contained under pressure at a level at least slightly above the level of a pressure differential which has built up across the filter element. The shock is applied for a period of 1-2 seconds, during which time the backflush reservoir is emptied.
Abstract: A small, simple device for cleaning type elements and print heads consisting of (1) a rigid, yet flexible, plastic backing, onto which is bonded (2) a soft absorbent material which has been wetted with (3) a solvent cleaning solution.
Abstract: This invention relates to a convertible step/extension ladder which allows to use one or more of extension sections with a basic A-shaped ladder frame. The extension sections are slidably mounted on legs of the frame through the use of housing/sliding rail arrangement on the legs of the frame and on the extension sections. When converted to an extension ladder, the basic frame portions are folded and locked in that position, while one extension section is moved along the frame portion to rest on the ground. If more than one extension sections are used, the second extension section is mounted on the opposite frame portion and extended upwardly, so that the basic frame portions form a middle part of the ladder.
Abstract: The invention relates to a safety chock valve having improved body top. An upper part of the valve body has a tapered wall cavity which receives in a sealed engagement a tapered lower part of the valve bonnet. An internally threaded cap member secures sealed position of the bonnet on the valve body. Even partial disengagement of the threads causes breaking of the sealed engagement and escape of pressure between the valve body and the bonnet.
Abstract: A rechargeable garden sprayer includes a container having an opening on an upper face, a lower suction tube, and an inlet formed at a side thereof. The inlet cooperates internally with the main body of the container such that liquid poured in through the inlet flows to the container. An engaging body has a base with about the same shape and size as the upper face of the container so as to be mounted on the container. The engaging body includes a number of upstanding hollow tubes along its periphery and a fixing panel to define a retaining recess. A top cover having substantially an inverted U-shaped body has two side panels with a number of downwardly extending poles at an inner side thereof for inserting into the hollow tubes and thus engaging with the engaging body. The top cover has a handle on its uppermost part.

Abstract: A toy car having a two-level cam, sound assembly, projection assembly, signal light, and a signal light activation arm. The two-level cam includes an upper and a lower cam and is driven indirectly by a battery-powered electric motor and a series of gears. The upper cam drives the projection assembly to project toy figures out of the car doors and springs cause the toy figures to return to their original position. The lower cam urges a spring-loaded signal light activation arm to urge a signal light to be intermittently rotated into position. Another cam indirectly drives a reverberation arm to move and also causes two lights to move. The sound assembly includes a sound-generation device, reverberation hole, and sound emission hole, with the sound-generation device being driven directly by the motor.
Abstract: A hydraulic shock absorber for a vehicle comprising a hydraulic cylinder with a piston which divides the cylinder into an upper compartment and a lower compartment, a damping chamber, and a return chamber. A control valve is provided in the path from the damping chamber to the upper compartment. A shock sensor is provided to detect the shock to which the vehicle is subject. When the shock exceeds a predetermined level, the shock sensor will give a signal to the control valve to close it, thus ensuring the shock to be absorbed by a spring in the damping chamber.
Abstract: An adjustable ski carrier having a flexible rope with two snap locks on each end. A handle provided on the rope has inwardly extending slots on each end of the handle. A pair of spaced apart apertures made on the opposite side of the handle are adapted to receive the rope from within a handle and extended over the top of the handle on the outside of it. A distance between the apertures is smaller than the distance between the most inward ends of the slots. The length of the rope in relation to the snap locks can be adjusted by extending the loop created by the part of the rope lying atop of the handle so that the device can be used for carrying the skis up the slope or down the slope in a balanced manner, and with the handle being fixed in a certain position by means of the slots in combination with the apertures and the loop. A knot created atop of the handle from the loop can be used to further ensure a fixed distance between the handle and the snap locks on the ends of the rope.
