Abstract: ABSTRACT OF THE DISCLOSURE An improved method of producing a compressible layer to be utilized for a blanket for printing operation is disclosed, wherein the improvement con-sists in that the method comprises the steps of adding to elastomer compound of oil resistant polymer pulverized material which is dissolvable in effluent  plac-ing the elastomer compound over a base fabric in the form of a layered structure and subjecting to vulcanization and then immersing it in the effluent at a pre-determined temperature for a certain period of time.  To improve compressibility one or more another compressible layers are preferably placed over the early pre-pared compressible layer with adhesive agent interposed therebetween so as to form an integrated structure.  A method of producing a compressible blanket for printing operation is also disclosed according to another aspect to the inven-tion  wherein after completion of producing of the compressible layer the latter is coated with adhesive agent at a predetermined rate of coverage in such a manner as to allow it to penetrate into a number of voids in the compressible layer and a reinforcing material is then placed over the compressible layer so as to adhesively integrate the former with the latter.

Abstract: ABSTRACT           A roller guide for use in a continuous casting installation for steel is divided into segments.  Each segment includes a fixed guide member which rests on a base and a movable guide member which is supported by the fixed guide member.  The guide members carry rollers which cooperate to define a path for a continuously cast steel strand.  The fixed guide member has a series of hollow columns which are aligned with respective tubular elements provided on the movable guide member.  Spacers for adjusting the distance between the rollers are disposed between the columns and tubular elements. A tie rod extends through each column and has a first end located externally of but adjacent to the respective column.  The first end of each tie rod has a passage which registers with a corresponding passage in the base.  Each pair of registering passages receives a locking pin.  The locking pins connect the tie rods to the base and indirectly connect the fixed guide member to the base via the tie rods.  Each tie rod has a second end located in one of the tubular elements of the movable guide member.  A compression spring in each tubular element reacts against the associated tie rod and against the movable guide member thereby urging the movable guide member towards the fixed guide member.  The action of the compression springs also causes the locking pins, and hence the fixed guide member, to be braced against the base.  A piston-and-cylinder unit mounted inside each tubular element is arranged to act against the adjacent end face of the associated tie rod counter to the respective compression spring.  When pressure fluid is supplied to these units, the locking pins are released and the movable guide member is displaced away from the fixed guide member.

Abstract: Abstract of the Disclosure According to image-forming processes of a method and apparatus of electrophotography used for a printer or a copying machine, a toner having no photocon-ductivity is applied on a surface of a photoconductive layer of a photoreceptor consisting of a transparent conductive layer and the photoconductive layer which are sequentially formed on a transparent substrate.  The photoconductive layer is exposed from a side of the transparent substrate.  Toner particles on an exposed region of the photoconductive layer are transferred to toner-receiving paper opposite the photoconductive layer so as to form a toner image.  A process for developing a latent image can be omitted.  In addition, a special toner such as a photoconductive toner having low sensitivity is not used, thereby forming a high-quality image.  The apparatus of electrophotography becomes simple and compact.

Abstract: ABSTRACT The invention comprises a process for stripping disks coated by a process in which the disks are rotated at high speed during a media application step, then immersed in an orienting magnetic field, and finally dried at low speed.  If a flaw is detected after drying, according to the stripping and recoating process of the present invention, the disk is simply stripped and recoated by merely repeating the high speed coating step.  During stripping and recoating, the nozzle starts at the outside diameter and moves toward the inside diameter.  As the nozzle moves from outside diameter to inside diameter, the new media which is discharged from the nozzle onto the disk strips away the old media layer.          Once the nozzle reaches the inside diameter, it moves back toward the outside diameter and applies a new layer of media to the disk.

Abstract: MACHINE FOR CLEANING SURFACES SUCH AS    CARPETS, FLOORS AND THE LIKE                           ABSTRACT          A machine for cleaning surfaces such as carpets, floors, and the like, has a frame (30) on which is mounted an upper housing (56) containing an air pump (62).  An assembly of a fresh liquid container (48) stacked on a waste liquid container (50) is removably mounted on the frame with the aide of a cam latch (54).  The air pump communicates with a housing (160) which provides pressurized air to outlets (158, 166, and 168) and suction to a suction nozzle (46) through a conduit (173) which carries waste liquid and air picked up from the carpet to a separator (58) in the housing (56).  A cleaning fluid container (64) is removably mounted in a docking port (68) in the housing (56) and aligned and locked in communication with couplings (254) in the docking port (68) by a rotatable collar (66) having a camming recess (220).  The clean liquid container (48) and the cleaning fluid container are pressurized by connections thereto from the air pump outlets (166 and 168) to provide for the delivery of fresh liquid or fresh liquid and cleaning solution mixtures of selected concentration to a spray nozzle (42) to which pressurized air is also applied from one of the pressurized air outlets (164) via a conduit (158).          The delivery and concentration of the fresh liquid and/or cleaning fluid is controlled by a actuator (40) which operates a rocker arm (102) for constricting tubing associated with a coupling (90, 126) in which the pressurized cleaning fluid and fresh liquid are combined.  The suction nozzle has a passage (274, 276) for facilitating flow of air and waste water and making such flow visible,  The separator (58) includes a conical shroud (172) which facilitates separation of waste liquid from the air picked up from the surface being cleaned.  The assembly of fresh water and waste water tanks (48, 50) has a conduit (181) leading from the bottom of the separator housing (160) through the fresh liquid tank into the waste liquid tank.  A keyway (184) on the tanks facilitates their alignment with a member on the frame (30) containing the conduits (158 and 173) for the pressurized air to the spray nozzle and the air and waste liquid from the suction nozzle and which provides a key for alignment of the assembly of containers (48 and 50) on the frame (30).  The cleaner may be rolled on wheels (32) by a handle (36) connected to the frame (30).

The total concentrations of the isoelectronic impurities should be larger than 10   atoms/cm and the difference between " a " and "ao " should be less than plus or minus 2%.  The size effects of the under- and over-impurities compensate each other in the double-impurity-doped crystal of the present invention.

Abstract: ANTI CLOSURE DEVICE FOR FLEXIBLE CONTAINERS               Abstract of the Disclosure Flexible plastic container bags used for the bulk storage and dispensing of fluids are often blocked from dispensing all the contents and/or entrap part of the contents in folds of the plastic as they shrink during dispensing.  A tongue or dip tube is attached to the inner wall of the plastic bag near the location of the dispensing aperture.  The tongue is formed of a laminate of two dissimilar materials, one non-hygroscopic and the other hygroscopic, so that upon introduction of moisture into the bag, the hygroscopic layer will expand and the normally flat tongue will curl to form a thick tube that both prevents collapse of the bag and prevents closure of the dispensing aperture by the opposite wall of the bag.
