Abstract: An apparatus for exposing the fibrous reinforcements of a fiber reinforced resin body comprises at least one stage in which a portion of the resin body is brought into contact with a heated resin removing liquid while the resin body is vibrated. According to this apparatus subsequent processing of the resin body, e.g., connecting to another similarly treated resin body, can be advantageously conducted by utilizing the exposed fibrous reinforcement.
Abstract: A process for separating ceramic nuclear fuels out of metallic support mers or support member parts in which there adhere the nuclear fuels, especially subsequent to the burning down of the nuclear fuels in nuclear reactors. The ceramic nuclear fuels are washed off from the support member or carrier member part by means of a liquid jet which stands under a high pressure. The liquid jet is directed against the nuclear fuel, and the pressure of the liquid is set so high, that the nuclear fuel which adheres to the support member is completely removed. The liquid jet finds the transition from the ceramic nuclear fuel to the metallic support member material such that, even at a swelling of the fuel rod, and deformation of the support member part, there is achieved an efficient detaching of the nuclear fuel. The metallic support members or support member parts hereby remain intact and are segregated after the washing off of the nuclear fuel. Only the nuclear fuel fragments are introduced into the chemical solvent.

Abstract: An assembly which is used with an undergravel aquarium filter in order to keep the passage between the bottom cavity under the filter and the uptake tube free from blockage due to gravel. The assembly is in the form of a collar which extends from the bottom plate of the undergravel filter at the point of insertion of the uptake tube. A ring, with a structure to prevent the passage of gravel through the central portion thereof is fitted within the collar. The ring may be removed from the collar to clear gravel out from the collar before insertion of the uptake tube.
Abstract: Method and apparatus for removing extraneous matters from cooling water used in a tubular heat exchanger such as a condensor is disclosed. When a pressure difference between the portions upstream and downstream of a filter element exceeds a predetermined threshold value set in advance in accordance with the flow rate of the cooling water, a blow-down operation is started to remove the extraneous matters scraped off of the outer peripheral surface of the filter element by a turning flow. The extraneous matters are removed at a rate of clogging of the filter element of 50%, irrespective of the flow rate of the cooling water. The clogging rate can be sensed accurately, and the blow-down operation is effected with necessary and sufficient frequency.
Abstract: A method for washing an inner surface of a tubular permeable membrane which comprises:a friction piece having a hardness of from about 10.degree. to 30.degree. measured according to JIS K6301, 5-2 attached to an end of an elastic rod-like support, andoperating the support to reciprocate the friction piece within the tubular permeable membrane to thereby act a rub-washing force of from about 0.1 to 1.0 kg/cm.sup.2 between the inner surface of the tubular permeable membrane and the friction piece so as to remove contaminants adhered to the inner surface of the tubular permeable membrane.
Abstract: A fat recirculating system with an external, gas-heated heat exchanger for a deep fat fryer is disclosed. The use of such a system necessitates recirculation also of cleaning solution and rinse water through inaccessible plumbing of the recirculation system whenever fat is to be replaced. To remove residual water droplets from the plumbing after rinsing, a "dry cycle" is utilized. The dry cycle includes intermittent application of heating and cooling of the empty heat exchanger, resulting in a substantial reduction in start-up time when the fryer is refilled and operation again commenced.
Abstract: A unitary disposable chamber and filter unit including a method for making same in which a support surface on the chamber has energy directors such that when ultrasonic energy is applied thereto the energy directors will become molten and bond a filter card to the support surface at spaced locations away from the point of discharge of the fluid through the filter card onto a microscopic slide or other surface for analysis.
Abstract: Disclosed is an apparatus for recovering solid particulates in liquid, typically water containing precious metal particles, such as is produced as a by-product of jewelry manufacture. The apparatus has a settling tank, which contains a fabric trap for entrapping very fine particles. Water in the tank is moved through the trap by a syphon producing a very small pressure gradient across the trap, which, because the pressure is so small, enables one to use a trapping fabric of much larger mesh than has been possible heretofore.
Abstract: An electrically powered automated golf club grip cleaning unit for sequentially cleaning a full set of golf clubs essentially as fast as the operator can insert and withdraw the clubs from the unit. The automated unit comprises a closed, water tight housing that is divided into an upper and a lower compartment having a rotating (carousel-like) lid that accepts a plurality of inverted golf club shafts and grips through openings into the top compartment and spins the clubs while advancing them through a wash and rinse zone while making abrasive contact with spinning brushes within the upper compartment and simultaneously recycling wash water as well as rinse water accumulating in partitioned reservoirs in the lower compartment back to the upper compartment for cleaning the grips of the golf clubs. The apparatus further provides continuous bleed-off of some of the recirculating rinse water and make-up of fresh water.
Abstract: A cleaning and scrubbing apparatus is described which consists of a vacuum head to which is coupled small hollow fibers. Each of the fibers has a diameter of approximately the size of the record groove so that it may fit within the record groove to scrub away debris formed within the groove. A cleaning fluid is be placed over the record to partially dissolve the debris so that the fibers can loosen it as the record is rotated across the fibers. The vacuum causes the cleaning fluid including the debris to be sucked through the hollow opening of the fibers. The side walls of the fibers may be a membrane material so that additional fluid flows through the side walls. In order to clean the cleaning head, the fluid is forced in the reverse direction while the head and fibers are facing upright, thereby washing away the debris which has become affixed to the fibers.
Abstract: Methods of an apparatus for cleaning an electro-mechanical transducer such as a "mouse" used for moving cursors on a computer display terminal comprise a scrubbing ball having a "hook" VELCRO surface and a pad having a "loop" VELCRO surface. The VELCRO covered ball is lightly coated with solvent, inserted into the recess of the "mouse" and rolled over the "loop" VELCRO surface. This rolling action scrubbs the interior of the "mouse" and transfers dust, debris and suspended oil from the recess of the mouse to the pad.
Abstract: A process and for improving the automatic emptying and cleaning of hygienic vessels or receptacle under conditions providing for the optimum infeed of rinsing water and for a minimal water usage.
Abstract: Apparatus for controlling an infinitesimal flow rate of fluid comprises at least one filter means (3, 3A, 3B, 3C, 3D, . . . ) provided in a fluid passage and capable of setting to a predetermined filtration amount, thereby regulating the flow rate of the fluid by controlling fluid supply to said filter means. The present apparatus may be used in a vacuum processing system.
Abstract: Disclosed is a high efficiency deep fat fryer from whose fry tank fat is continuously withdrawn for heating and filtration. A pump circulates part of this fat through a helical- or serpentine-shaped finned-tube heat exchanger positioned between a gas-fired burner and the bottom of the fry tank. The remaining portion of fat is directed through a filter located in the bottom zone of the fry tank. The fryer includes a control system with sensors such as pressure switches for preventing damage to the fat at low flow rates and devices for expelling moisture trapped in the pump. The filter has an element of material such as carbon-impregnated cloth which may be quickly replaced without draining fat from the tank.
