Abstract: Abstract of the Disclosure A novel flush hasp for use in conjunction with a boat hatch, door or the like, the hasp having a base portion (20, 50, 80) adapted to be mounted on a boat deck or door jamb adjacent the hatch or door.  This base portion is utilized in conjunction with a movable hasp member (12, 42, 72) adapted to be mounted on the hatch or door and movable therewith toward or away from engagement with the base portion.  The base por-tion is provided with a locking means (30, 60, 90) rotatable between locking and release positions, whereas the movable hasp member is provided with an aperture (32, 62, 92) designed when adjacent the base member to receive the locking means and closely interact therewith.  In accordance with the first two embodiments of this invention, the base portion has locking means in the form of a closed loop (30, 60) that may be rotat-ed while extending through the aperture of the movable hasp member so as to tightly engage the movable portion of the hasp and thus achieve a latching of the hatch or door in the closed position.  At such time the closed loop may either be in a folded down position wherein the likelihood of a passen-ger on the boat tripping is minimized, or it may be utilized in an upstanding position so that the shackle of a padlock may be passed through the loop in order to achieve a locking o the hatch.  Another embodiment of this invention involves the use of a rotatable member (90) having at least one lug (91) on its upper surface, which lug on occasion may enter the aperture (92) in the movable hasp portion.  Locking means (98), preferably key (95) operated, is provided so that movement of the lug to the release position can be prevented except when it is desired to open the hatch.

Abstract: ABSTRACT OF THE DISCLOSURE        Apparatus and method for removing and cutting tubes which have become damaged in a nuclear reactor.  The apparatus for accomplishing this object includes a base secured to the header of the heat exchanger by expanded mandrel mechanisms. A carriage is suspended from the base on screws which are driven by a motor to move the carriage away from and towards the base.  An OD gripper assembly is suspended from the carriage and is movable by rods away from and towards the carriage.  An ID gripper assembly extends through the OD gripper assembly. The gripper of the ID assembly is actuable to engage the internal surface of the tube portion.  With its gripper so engaged, the ID assembly is engaged by the gripper of the OD assembly and the engaged tube portion is pulled out of the header by the OD assembly.  The ID gripper is then disengaged and the OD gripper is engaged with the tube portion in the same was that it engages the ID assembly and the tube portion is pulled out further.  A tube cutter having an abrasive wheel then cuts lengths of the tube at an angle so that for examina-tion and testing the tube lengths can be matched and oriented with respect to each other and the defect evaluates.

Abstract: DISPLACEMENT CONTROL FOR A HYDRAULIC PUMP      OR MOTOR WITH FAILURE OVERRIDE                       Abstract A displacement control for a pump or motor having a swash plate for setting displacement includes a control device operatively connected to the swash plate and a control valve having connections to a source of pressure and drain for operating said control cylinder.  The control valve has a neutral position wherein the swash plate is at or near a minimum displacement position.  The control valve is operable to other positions for setting the displacement of the pump or motor and, additionally, is movable to a control position other than the neutral position or normal displacement-setting positions in response to an operative failure of the control valve positioning system which enables the swash plate to move to a position which minimizes any adverse effects from the occurrence of said operative failure.  In a pump, the swash plate moves to a zero displacement position upon the occurrence of a failure while, in a motor, the swash plate moves to a maximum displacement position.

Abstract: ABSTRACT OF THE DISCLOSURE       There is disclosed herein an electric heater plate which is formed on a ceramic substrate such as a glass sheet.  A nonconductive coating overlies at least a portion of a surface of the ceramic substrate.  This nonconductive coating has at least one open area therein in which the surface of the ceramic substrate is exposed.  A conductive coating overlies at least a portion of the nonconductive coating and at least a portion of the surface of the ceramic substrate exposed by the open area formed in the nonconductive coating.  A conductor is bonded to the conductive coating at the location where the conductive coating overlies the surface of the ceramic substrate exposed by the open area formed in the nonconductive coating.

Abstract: ABSTRACT Semiconductive photoanodes formed of titanium dioxide (TiO2) are known for use in photoelectrochemical cells.  They have been made by various techniques, including chemical vapour deposition, thermal oxidation or anodic oxidation of thin titanium foils, hot pressing of TiO2 powder, and plasma spraying.          The present invention provides a method for the fabrication of TiO2 thick film photoanodes, which method is simple, inexpensive and suitable for mass production of large area plates.  The method comprises screen printing a film of conductive material on a clean alumina substrate which is then heated to fuse the conductive material into a conductive layer.  A first layer of TiO2 particles in an organic carrier is then screen-printed over the conductive layer, at least 10% of the TiO2 being of anatase form.  The structure is then heated to burn off the organic carrier and to transform at least part of the TiO2 from anatase form to rutile form, this resulting in good adhesion of the TiO2 layer to the conductive layer.  A second layer of TiO2 is then screen-printed over the first layer and heated, the second layer being provided in case there should be pinholes in the first layer which would adversely affect the anode structure when submersed in an electrolyte.  The resulting structure is then heated in a reducing atmosphere, e.g. anhydrous ammonia or hydrogen, to transform the TiO2 to TiO2-x  where x is between 0 and 1, to reduce the electrical resistivity of the films.

Abstract: ABSTRACT OF THE DISCLOSURE            A fluid pressurizing device 10 having a master cylinder 12 with a cylindrical projection 52 that extends through the housing of a brake booster 14.  The housing of the brake booster 14 has a front shell 56 located on a shoulder 54 of the cylindrical projection 52 and a rear shell 140 located against a shoulder 150.  A nut carried by the cylindrical projection 52 engages the rear shell 140 to compress a bead 111 of a diaphragm 110 against a shoulder 57 on the front shall 56.  A sleeve 80 connected to a hub member 70 retains a bead 108 of diaphragm 110 and bead 90 of a diaphragm 92 connected to the cylindrical projection 52. In response to an input force, a valve assembly 136 controls the development of a pressure differential across the diaphragms 92 and 110.  The pressure differential acts on and moves the diaphragms 92 and 110 toward the first shell 56.  Movement of the diaphragms 92 and 110 is carried through the hub member 70 which moves in slots 62 and 64 in the cylindrical projection 52 to provide a piston assembly 30 in the master cylinder 12 with a force to pressurize fluid therein and develop an output fluid pressure to effect a brake application.
