Abstract: RESTORE METHOD AND APPARATUS FOR DISK DRIVE      ABSTRACT OF THE DISCLOSURE           A method and apparatus for restoring the electro-magnetic read/write head of a disk drive from a position between a data-field track located closest to the axis of rotation of a disk loaded in the drive and a data-field track located furthest to such axis of rotation, to a position over the latter data-field track.  A first predetermined code is prerecorded on each data-field track and a second predetermined code is prerecorded on each of a plurality of guard-band tracks. The head is first moved in a direction away from the axis of rotation of the disk at a predetermined velocity.  The code stored on each track is read and detected as the head is moved thereover.  The head is stopped over a track when the code read and detected therefrom is the second predetermined code.  Then, the head is moved in a direction toward the axis of rotation of the disk and stopped over the data-field track located furthest from the axis of rotation of the disk.

Abstract: ABSTRACT OF THE DISCLOSURE     A valveless pump system having two moving parts consist-ing of a cylinder with a piston therein defining a pump chamber.          An inlet part communicates with a dip tube which extends into a container and permits the product in the container to pass into the pump chamber.  An outlet port allows for the product thus drawn to be dispensed from the pump chamber.  The pump is actu-ated by pressure directed axially on the piston, forcing it into the cylinder.  Fitted with a return device the piston is allowed to reciprocate in the cylinder alternating between a suction and compression stroke.  During the suction stroke product is drawn into the pump chamber by way of the inlet port while the com-pression stroke provides for the dispensing of the product thus drawn via the outlet port.  The system is equipped with passages and channels sufficient to accomplish the operation of drawing and dispensing the product in addition to providing for the vent-ing of the container.  The suction stroke provides for air to be drawn through the outlet part from the ambient into the pump cham-ber, advantageously removing any residual product from the outlet part where this is desirable.  In certain applications the air is drawn into the pump chamber to assist in the dispensing of the product during the compression stroke.  The introduction of air into the pump chamber also assures the presence of an air pocket therein, thereby maintaining a resiliency in the system thereby preventing piston "hang up".    Embodiments of the pump system are disclosed having a vertical pump axis equipped with adverti-cally reciprocal finger actuated button or having either a ver-tical or horizontal axis with a trigger actuator.  Different cylinder and piston configurations are disclosed facilitating commercial applications of the system.

Abstract: ABSTRACT OF THE DISCLOSURE:         A  readily  assembled  transducer  assembly.    The assembly includes a cup-shaped non-magnetic housing for the transducer magnetic structure.  The housing has one or more slots for receiving the pole piece tips and nesting members for  positioning  the  coil  bobbins,  the  pole  pieces  and permanent magnet within the housing.  The cup is placed on a plate of magnetic material so that the pole tips are attracted to the plate and held firmly in place.  With the pole tips held,  a potting  compound  may be  introduced  into  the  cup cavity.  As the compound is hardening,  terminals and a cap cover may be applied.  When the compound has set, the assembly is removed and is ready for  use.   The  magnetic  assembly housing has an external peripheral screw thread for mating with a threaded wall of the armature and diaphragm assembly.          During the mating process, the air gap adjustment between the magnetic assembly and armature may be set at a desirable level and maintained.

Abstract: A B S T R A C T An atomic beam tube provides a single sealed envelope structure that serves both as vacuum envelope and as structural member to which the operative components are attached.  The envelope is composed of a heavy and relatively rigid frame and a relatively thin and flexible cover sealed to the frame.  The operative elements are separately assembled in independent sub-assembly units which are secured to the frame at a minimum of locations to provide fixed alignment and thermal isolation of the operative elements, and easy disassembly of the tube.  The molecular beam tube apparatus comprises enclosure means, a source for providing a beam of molecular particles a first state selector for selecting a portion of the particles in the beam, a radio frequency transition section downstream from the first state selector for causing resonance transitions of some of the selected beam particles means for producing a weak generally homogeneous magnetic field in the radio frequency transition section, a second state selector downstream from said radio frequency transition section for selecting a further portion of the bean comprising these beam particles that have undergone resonance tran-sitions, and detecting means responsive to the particles in the further portion.  The source and first state selector together comprise a first sub-assembly, the radio frequency transition section and the means for producing a weak field together comprise a second subassembly, and the second state selector and the detecting means together comprise a third subassembly.  The enclosure means comprise a rigid base and a flexible cover, the frame and cover being sealed together to form a vacuum envelope.  The three sub-assemblies are separately and removably secured to the frame.

Abstract: ABSTRACT Power-operated apparatus is provided for applying roof-top material such as vinyl, plastic, leather or the like, directly to an automobile roof or to a rooftop form.  The ap-paratus includes a plurality of clamping brackets for respec-tively clamping a rooftop material blank at spaced-apart locations thereon while it is on the rooftop or form.  Each clamping bracket is coupled to fluid-actuated cylinders, which are in turn coupled to fluid supply and control means for applying a pulling force on the clamping brackets and tensioning the rooftop material blank for seating it into the desired shape and position on the rooftop or form.  All the clamping means are pulled simultaneously to maintain the forces on the rooftop material blank in equilibrium.        If the rooftop material blank is applied directly to the vehicle roof, cement is first applied to the rear surface of the material blank and to the vehicle roof.  If the rooftop material blank is being applied to a form, it is first coated with a thermosetting material and the form is preheated for activating the thermosetting material.  The seated and shaped blank is held on the form until the thermosetting material has set so that the blank retains the desired shape.        A system is also disclosed for mass production of preshaped rooftop material blanks, wherein several forms are mounted on a turntable-type conveyor for carrying them through several stations for heating the forms, applying and tensioning the material blanks, curing the thermosetting resin and remov-ing and trimming the shaped material blank.

Abstract: ABSTRACT         A high pressure multi-purpose seal for use with pressure vessels and other equipment requiring demountable access fittings withstands pressures thousands of times above atmospheric pressure at both cryogenic and elevated temperatures.  The cryogenic high pressure seal comprises a stack of indium, brass and fluorocarbon plastic sealing rings disposed about an access opening in the pressure vessel.  A gland nut type closure is tightened against the seal stack which compresses it and causes the indium rings to extrude and seal against the closure and pressure vessel walls.  The seal exhibits negligible leakage and provides exceptional pressurization and depressurization cycle life at both high pressures and cryogenic temperatures.          The instant invention also comprehends a high pressure seal suitable for use at elevated temperatures (370° to 400°          Celsius or 700° to 750° Farenheit).  Substitution of aluminum rings or rings of a material having similar temperature and stress characteristics for the indium rings and substitution of perfluorelastomer rubber rings for the fluorocarbon plastic rings extends the operational temperature range of the seal upward several hundreds of degrees.
