Abstract: A suspension system for a vehicle such as a trailer or tractor wherein ground-engaging wheels on an axle are mounted on a pair of control arms, which in turn are pivotably mounted for vertical swinging motion at one end to frame brackets laterally disposed at opposite sides of the vehicle frame. Spring means are disposed in a load-transmitting relation between another end of the control arm and the vehicle frame. The pivotal connection between the frame bracket and the control arm includes a bolt which passes through an aperture in the control arm and slotted apertures in the frame bracket to provide fore and aft adjustment of the control arm at the pivotal connection. This slotted connection facilitates alignment of the axle relative to the vehicle frame. The bolt is carried in the slotted adjustment apertures by special mounting plates which have means for pivotably supporting the plate on the frame bracket and means for gripping the mounting plates for movement with respect to the frame brackets.

Abstract: A shaving cutter having a circular array of teeth of the same number and approximate size as that of a gear to be shaved, and having cutting edges at one end of the teeth of identical profile as that to be formed on the gear teeth, the teeth of the cutter being backed off to provide cutting clearance and dimensioned to be received simultaneously in all of the tooth spaces of the gear with circumferential clearance. Relative reciprocation is provided with timed relative circumferential depth feed to shave first one side and then the other of the gear teeth. The teeth are provided with cutting edges occupying different planes to avoid having all teeth initiate cutting action at the same time.

Abstract: A latch mechanism for a vehicle seat whose seat back and seat cushion components are fixedly mounted on a seat base that is suspended on a sub-base for oscillating forward and rearward movement with respect to the vehicle so as to isolate the seat occupant from longitudinal vehicle vibrations. The latch mechanism includes a keeper fixedly mounted on the sub-base and having forwardly and rearwardly facing latch surfaces. A latch member of the latch mechanism is pivotally mounted on the seat base and is movable between latching and nonlatching positions with respect to the keeper. The latch member has forwardly and rearwardly facing latch surfaces in the latching position that respectively engage the rearwardly and forwardly facing latch surfaces of the keeper to hold the seat against the oscillating movement in a rattle-free manner when a seat occupant desires a fixed seating position such as when vehicle controls must be manipulated during parking and backing operations.

Abstract: Machine tool structure designed to reduce the noise incident to operation. The invention is illustrated and described as applied to a vertical broaching machine in which the frame structure is modified by supporting the operating components on a vertical slab or thick plate reinforced with longitudinally extending ribs and including an open truss type support rather than the conventional hollow or enclosed columnar frame in common use.

Abstract: A gear shaped tool formed of a relatively soft elastically deformable material provided with a multiplicity of pores provided in the sides of its teeth by elimination of solid particles exposed at the surface thereof is rotated in mesh under light pressure contact with a work gear, while a very fine abrasive fluid polishing compound is provided. The operation improves the surface finish of the teeth of the work pieces without appreciably affecting the tooth form. The operation may be carried out with the axes of the gear and polishing tool parallel or crossed at a small angle and a relative traverse may be provided between the gear and tool in a direction which occupies a plane parallel to the axes of both the gear and tool, such direction preferably being parallel to the axis of the gear.

Abstract: A vehicle seat support assembly including a fluid spring that supports an upper seat base on a lower floor base at a vertical height corresponding to the adjusted position of an adjustable control linkage which extends between the seat base and a time delay valve whose operation controls the amount of pressurized fluid within the fluid spring. The control linkage includes an adjustment link pivotally mounted on the seat base for adjusting movement and connected to one end of a connecting link whose other end is connected to an actuating link that controls the valve. The control linkage actuates the valve so that the seat base is positioned at the same vertical height for any adjusted position of the linkage regardless of the seat occupant's weight. The control linkage is adjustable to vary the height at which the seat base is positioned and is prevented from transiently actuating the valve during dynamic vertical movement of the seat base by the time delay operation of the valve.

Abstract: Disclosed is data storage and transfer apparatus forming a sub-system of a data display terminal of the type in which a page of characters arranged in rows and columns are displayed on a television monitor by means of converting a plurality of character-representing data words into a pattern of pulses that control the intensity of the television beam during the course of its raster scan. An advantageous composition of text on the display screen is obtained in that the number of characters per row is not arbitrarily limited to being a power of two. There is provided a multi-location random access memory (RAM) having sufficient storage capacity to store all the data words for a full page. Circuitry is provided for addressing the RAM by address pointers that are represented in matrix notation. The circuitry includes address converter circuitry for converting the address pointers to absolute addresses for selecting locations of the RAM in connection with the transfer of data words into and out of the RAM.

Abstract: A reciprocating pump fabricated from an assembly including a body having a cylinder bore formed therein for receiving a reciprocating plunger, and with a transverse bore extending radially outwardly from the cylinder bore at a certain axial position, and passing through the wall of the pump body. A counterbore is formed along the cylinder bore and is arranged to receive a stacked assembly of guide means, packing means, and lantern ring means. The guides are operative to control the radial thrust on the plunger, while the lantern ring is arranged to provide communication from the interior of the cylinder bore to the atmosphere. The packing means includes a pair of axially displaced ring seals, one each being disposed on opposite sides of the lantern ring, and providing for mutual isolation between the pumping chamber of the pump and the crankcase.

Abstract: The device is arranged to receive a plurality of separate groups of signals, each group including a given number of redundant digital signals and is to select one of the digital signals from each group for subsequent processing. Memory sections are provided for storing at specific locations in each of the sections the digital signals of the various groups. A clock and counter are used to control an addressing circuit for cycling the addressing of the respective sections and locations such that the digital signals in each group may be successively stored in suitable buffer registers on a time share basis. The redundant signals in each group are then successively released for independent analysis, a preferred or favored digital signal among the redundant signals being selected and stored in a high speed memory section. These stored preferred signals from each of the groups are then available for subsequent processing.

Abstract: A control mechanism to dampen gimbal tumbling and to orient the axes of rotation of the rotor and the gimbals of a gyroscope when in an inoperative state. The control mechanism serves as an overriding stop to gimbal lock, dampens the gimbal rotation leading to tumbling and restores the gimbals to a given orientation upon the cessation of gimbal rotation. The overriding stop and dampening force in one embodiment are the plurality of cams and cam followers rotatably mounted and operatively connecting the inner and outer gimbals with the gyroscope frame, and in another embodiment a cam and cam follower arrangement rotatably mounted and operatively connecting the inner and outer gimbal in combination with a bearing surface operatively connecting the inner and outer gimbal with the gyroscope frame.

Abstract: A method and apparatus for establishing the azimuth position of a remote object is provided utilizing a north seeking gyro and a rotating transfer arm. Alignment devices such as an autocollimating telescope is provided at one end of the transfer arm for determining the relative position and alignment of the remote object to the transfer arm. A balance weight is provided at the other end of the arm to provide appropriate compensation for free rotation. The output of the north seeking gyro is connected to the transfer arm through an encoder while the telescope is rotatably connected to the transfer arm also through an encoder. The sum of the two angles measured by the encoders will provide the azimuth position angle for the remote object.

Abstract: A vehicle guidance mechanism for guiding a vehicle along a surface by means of an invisible guide line containing fluorescent material comprises an ultraviolet lamp that causes the guide line to fluoresce and emit visible light; photocell sensors mounted in the vehicle and adapted to sense the visible radiation and produce an error output signal proportional to the variation of vehicle position from a predetermined lateral position with respect to the guide line; and a control device in the vehicle adapted to steer the vehicle in response to the error signal so as to cause the vehicle to follow the guide line. An automatic contrast control circuit eliminates the effect of background illumination in the output signal and produces a constant closed loop gain with respect to the signal received from the guide line. Modulation circuitry and appropriate filters further reduce the effects of background illumination and improve the reliability and line detecting ability of the guide system.
