Abstract: A selection mechanism is disclosed which greatly simplifies the selection controls for a single element typewriter and thereby adapts it for inexpensive manufacture and reliable operation. A single continuous groove in the cylindrical periphery of a rotating shaft provides a universal surface similar to a cam surface to translate a follower member in a coaxial direction with respect to the rotating shaft and thus provide a linear movement which may be controlled in displacement and thus provide a defined or controlled input which in turn may be converted to a rotary motion for the typehead. The follower block is prevented from traversing any further than that distance which is desired and the follower is relieved by a spring bias member to allow it to ride out of the groove and thus allow the follower block to only traverse as far as permitted for a particular character selection.

Abstract: A gyro which has a fluidic bearing with two radially spaced circles of orces and two circumferentially and radially spaced exhausts and jet means for producing low pressures in the circumferential exhausts. By using a jet nozzle exhaust control with radial exhaust outlets between two circles of orifices, fluid from one circle of orifices is allowed to exhaust before it can interfere with the other circle of orifices. The fluidic bearing also has exhaust channels between each of the orifices to reduce turbulence and torques present in this area.

Abstract: An improved spooling device is provided having a drive shaft defining a track including conventional douple helices which are connected at their ends by parts of the track having any suitable curved or straight contour. An assembly on the drive shaft is made to reciprocate by engagement with the track for guiding a rope to and from a drum. The assembly includes two pivotal followers and a fixed center follower. When the assembly is moving axially in one direction, the pivotal followers are engaged in one helix and are in respective first positions. Then, when the assembly is returning in the opposite axial direction the followers are guided by the other helix and the pivotal followers are in respective second positions. Consequently the fixed follower and one of the pivotal followers take the load when the assembly is being moved in one direction whereas the fixed follower and the other of the pivotal followers take the load when moving the assembly in the opposite direction.

Abstract: A continuous run, single axis, single degree of freedom gas operated flui inertial gyro comprising a housing, a gimbal assembly supported in the housing on gas thrust and journal bearings, a turbine type spin rotor with axle mounting the rotor in the gimbal assembly, and shaft means forming part of the gimbal assembly and providing passageways to channel input flow to and vent flow from the gas turbine type spin rotor along and parallel to the gimbal axis to minimize drift error. The gyro is also provided with a pneumatic torquer to provide gimbal adjustment and fluidic pickoff to provide analog gas pressure readouts of pounds per square inch convertible to angular deflection in degrees.

Abstract: Noise and vibration are reduced in an axial cam drive mechanism by spring loading the rotary cam assembly to one end of its limit of axial travel. The spring load is applied through an antifriction axial thrust bearing, and is reacted by a second antifriction axial thrust bearing. The spring load applied exceeds the axial component of the maximum reaction load applied by the cam driven mechanism during operation so that there is no tendency of the rotary cam assembly to shift axially upon reversal of the reaction load.

Abstract: The motion converting device includes a double-threaded power shaft having two right-hand channels, two left-hand channels, and which is driven by a piston connected thereto. A power gear positioned in the path of movement of the rod has a central bore through which the shaft is received. The power gear is mounted in a guide block which holds the gear against movement axially of the shaft and which permits the gear to rotate. The guide block also has a bore through which the shaft extends. A spline connection operatively connects the shaft to the gear and permits the shaft to move axially of the power gear. First and second directional sleeves are mounted in the guide block at positions spaced axially from the power gear and are adapted to receive the rod therethrough. Each of the directional sleeves has at least one cam therein adapted to engage in one of the channels. The guide block holds the sleeves against axial movement while permitting them to rotate.

Abstract: A portable bracket assembly capable of being attached to the spindle carriage of a milling machine. A self-contained indexing table and indexing means is located on the assembly together with a transfer arm having three degrees of freedom and articulated fingers for selecting a tool holder from the indexing table and inserting the selected tool holder into the spindle of the milling machine when operated in a first direction and reversing the sequence when operated in the opposite direction. The assembly attachment allows a numerical controlled milling machine to perform sequential operations on a work piece that requires the use of a plurality of different individual tools.

Abstract: An automatic casting machine for automatically die casting and die trimming of zinc, aluminum, magnesium, lead or injection molding of parts and delivering the finished parts die trimmed free of flash and separated from the runners, gates and overflows into a finished parts receiver. The machine can be fabricated as a modification of a conventional die casting or injection molding machine, primarily by the addition of a centrally located indexing finger which becomes fastened to the sprew or bung upon casting or molding of the parts.

Abstract: Noise generation by machines having cam driven reciprocating elements is reduced in a machine wherein the cam-follower linkage comprises a double walled cam slot, a follower roller within the slot and spring means for moving the follower from the trailing wall to the leading wall of the cam slot.

Abstract: An improved traverse device of a winding apparatus for simultaneously taking-up a plurality of threads so as to simultaneously form a plurality of thread packages, the traverse device provided with a common traverse cam for creating traverse guide motion of a plurality of thread guides which are slidably mounted on a guide rail means disposed in parallel condition to a longitudinal axis of the traverse cam. The common traverse cam is provided with at least a pair of helical endless guide grooves formed on the cylindrical surface thereof and a ring shaped guide groove formed between the above-mentioned endless guide grooves. An axially inside portion of each of said endless guide grooves is connected to said ring shaped guide groove by way of an auxiliary guide groove formed on the cylindrical surface of said traverse cam. The guide rail means is provided with a cut-out portion at a position facing the ring shaped guide groove.

Abstract: A gyroscope rotor is rotated to a very high speed when a pawl is moved to release a ratchet coupled to a coil spring drive and keyed to a drive shaft. The coil spring drive then drives the rotor at a multiplied rate of speed through an arbor, planetary pinions revolved by the arbor and meshing with a fixed ring gear, a sun gear keyed to a drive shaft, the drive shaft, and hooking claw clutch teeth on the drive shaft and the rotor. When the spring reaches an unwound condition, the rotor overruns the drive shaft, the clutch teeth on the rotor cam the drive shaft axially away from the rotor, and a compression spring moves the drive shaft and a pilot pin thereon to retracted positions completely out of engagement with the rotor. A keeper bar on the pawl normally overhangs the ratchet to hold the drive shaft in clutching engagement with the rotor, and, when the pawl is released, it moves the keeper bar to a retracted position permitting axial movement of the drive shaft.
