The vehicle has a self-clamping mechanism to securely anchor itself at a work site in the main pipe and a tool actuating mechanism for angularly positioning and actuating the lining equipment. The lining equipment includes a lining material anchoring hydraulic press for pressingly hold an end flange of a tubular lining material, which is made of a fabric impregnated with a thermosetting synthetic resin, by an arcuate pressing plate. A counter hydraulic press counteracts the pressing force of the lining material anchoring press. A sealing tube having an electric heater element imbedded therein is sealedly bonded to an end of the tubular lining material with a bonding agent having a low melting temperature.

Abstract: A sterilizing apparatus has a vertical ultrasonic horn with an output tip at the low end thereof and an antiseptic solution holding receptacle that is disposed in a manner that a part of the horn is inside the holding receptacle and the output tip is below a bottom wall of the holding receptacle. An antiseptic solution is first supplied into the holding receptacle that temporarily holds the solution. The solution gradually and continuously flows out from the holding receptacle through outlet holes, which are located in the bottom wall of the holding receptacle and contiguous with the horn, onto the surface of the output tip of the horn so that the horn, while vibrating at the ultrasonic frequency, causes the antiseptic solution to be atomized on the output tip and changed into a state of mist with which the sterilization is performed.

Abstract: A surge absorber has an insulating body having a flat surface on which a pair of electrically conductive thin-film terminal electrodes and, therebetween, one or more electrically conductive thin-film discharge electrodes of a predetermined shape or shapes are formed. Micro discharging gaps are present between each of the terminal electrodes and any of the discharging electrodes adjacent thereto and between any of the discharging electrodes adjacent to each other. The discharging electrodes are typically arranged in a row and column pattern. A thermostatic fuse may be provided on the opposite side of the insulating body from the side of the flat surface on which the terminal and discharge electrodes are present. The substantial part of the surge absorber is hermetically sealed in an enclosure. The enclosure is filled with a gas such as an inert gas.

Abstract: A dc brushless vibrator motor employs a cylindrical coreless stator winding unit having at least three stator coils arranged at about an even pitch angle and a rotor that includes an axially extended eccentrically-weighted permanent field magnet that is magnetized so as to have alternate north and south poles about the rotational axis of the rotor. A cross-section of the field magnet in a plane perpendicular to the rotational axis has generally an arcuate or sectorial shape which is within an angular range of 180.degree. to 270.degree. about the rotational axis. The center of mass of the rotor, therefore, is off the rotational axis, thereby causing vibrations.

Abstract: A cooling apparatus has a cooling vessel, containing a liquid as a thermal medium which absorbs latent heat by evaporation, and an absorber which absorbs the vapor of the liquid. The cooling vessel further contains one or more units of encapsulated gel refrigerant submerged in the liquid, which impede temperature increase of the liquid when an operation of the cooling apparatus is temporarily suspended. An alternative cooling vessel has one or more upwardly extending members partially submerged in the liquid and covered with liquid soaking material, so that the liquid soaks up in the material by capillary action and accelerates its evaporation. Another alternative cooling vessel has plural liquid tanks, one arranged on another, so that the total area for the evaporation of the liquid is multiplied. An additional alternative cooling vessel has a plurality of rotatable fins, partially submerged in the liquid, for accelerating the evaporation of the liquid.

Abstract: An adsorption cooling apparatus includes a hermetically sealed cylindrical capsule that contains a first thermal medium, a moisture absorber on its first side and an adsorbent on its second side. The capsule reciprocatively moves and slidably contacts with a cooling vessel containing a low temperature thermal medium on the first side and with a heating vessel containing a high temperature thermal medium on the second side. The capsule is cooled by an external airflow when it is moved to the cooling vessel, so that the first thermal medium absorbed in the moisture absorber evaporates and the low temperature thermal medium in the cooling vessel is cooled because of the latent heat of evaporation of the first thermal medium. The so cooled low temperature thermal medium is utilized for cooling the object to be cooled. The first thermal medium having evaporated from the moisture absorber is adsorbed by the adsorbent.

Abstract: A dc vibrator motor has a generally cylindrically-shaped magnetically conductive case, a ring-shaped permanent field magnet, and an armature rotor including a shaft. The field magnet has at least four and at most eight alternate north and south pole sections arranged at an even angular pitch coaxially with the shaft. The armature rotor has at least three armature poles having an angular interval of 60.degree. between adjacent poles and at most six armature poles having an angular interval of 30.degree. between any pair of adjacent poles and at least six and at most twelve commutator segments arranged at an even angular pitch coaxially with the shaft. A pair of commutator brushes have an angular interval of at least 45.degree. and at most 90.degree. . Since all of the armature poles are situated within an angular range of 180.degree. about the shaft, the center of mass of the rotor is radially off the shaft, thereby causing vibrations.

Abstract: A dual-adsorber cooling system for an automobile has a pair of adsorbers, a cooling vessel, a pair of absorbate outgoing passages extending from the cooling vessel to each of the adsorbers individually, a common adsorbate return passage, a condenser, and a condensation passage. A bypass passage enables the two adsorbers to directly communicate each other to exchange heat. The adsorbers are opposingly disposed with an intervening plenum therebetween. The engine exhaust gas is introduced to the central plenum, and the external air is guided to the central plenum through the adsorbing adsorber so that a blend of the exhaust gas and the air is directed to the desorbing adsorber in the plenum, whereby the adsorbing adsorber is cooled and the desorbing adsorber is heated up. The amount of the external air taken can be controlled according to the amount of the exhaust gas. A process switchover controller can adjust the process cycle period according to the temperature of the exhaust gas.

Abstract: A vibrator motor has an armature rotor whose center of mass is off the axis of the shaft thereof. The rotor includes at least three poles each having an winding arm and an arcuate pole blade. All of the blades have an equal length and are disposed angularly evenly about the axis of the shaft so that all of the blade-to-blade spacings are equal. At least one winding arm is angularly out of alignment with the dimensional center of the arcuate blade of the corresponding pole, or, the size and the mass of at least one arm is different from those of any other arms, or, the mass of at least one of armature windings is different from the mass of any other armature winding, or, a weight is fixedly attached to the rotor in an eccentric manner either between two armature poles or on the shaft.

Abstract: A serpentine-type merchandise storing and dispensing column used for an automatic vending machine has a pair of opposing, generally vertically disposed wave-formed walls forming a serpentine merchandise storing space therebetween. Each wall includes a plurality of arcuate boards pivotally coupled to a frame and are disposed generally vertically in succession. The arcuate boards of one wall are disposed in a staggered arrangement with respect to the levels of the arcuate boards of the opposing wall. Each arcuate board is urged by a tension-spring so as to pivotally swing into the serpentine merchandise storing space. Thus, the board cushions descending merchandise in the serpentine merchandise storing space. Each arcuate board has a plurality of vibration absorbing slots and a plurality of beads between, and in parallel with, the slots.
