Abstract: An automotive tire bundling machine having a support framework or base which supports a pair of vertically spaced tire support members. A stack of tires are placed between the tire support members against guide rods on one of the tire support members. The other tire support member is moveable toward and away from the one tire support member for compressing the stack of tires. A strap feeding means position a strap about the peripheral edges of the stack of tires and is cooperative with a strap clinching device to tension the strap, secure the strap and cut off the excess strap material. The stack of tires is rotatable with the tire support members to facilitate the placement of additional straps about the stack of tires.

Abstract: A reliable signaling device is provided which will allow an operator of a reactor vessel to ascertain when a leak has occurred in the reactor vessel rupture disc or diaphragm. The signaling device is actuated by pressure which escapes through a leak in the rupture disc. The signaling device makes the operator aware of when a rupture disc is leaking and thereby avoids a potential hazard of the reactor vessel exceeding its designed pressure rating. The signal device when modified may also be used in vacuum operations.

Abstract: Electrical component leads, extending through apertures of a printed circuit board, are cut and clinched by reciprocating cutter blocks moved transverse to the axis of the leads. All the leads are cut with selected ones being bent to a greater extent than the remainder of the leads.

Abstract: A dot matrix printer including a single printhead having two columns of print wires, the wires in one column being used to print only odd numbered dot columns on a record member and the wires in the other column being used to print only even numbered dot columns on the record member. In one embodiment the wire columns are spaced apart a distance equal to an even number multiple of the space between two adjacent dot columns and the wires in each column are then energized alterntely as the printhead traverses the dot column positions. In another embodiment the wire columns are spaced apart an odd number multiple of the space between two adjacent dot columns and the wires in each column are then energized simultaneously as the printhead traverses the record member.

Abstract: This invention relates to a bearing assembly and more particularly to a bearing assembly which has parts slidable with respect to each other and with roller members therebetween so the assembly functions free from unwanted contaminating elements such as lubricants, chips, flakes, or the like, thereby rendering the assembly readily adaptable for use in environments such as electroplating applications which must be maintained clean of such unwanted elements.

Abstract: A data processing system includes a control processor in communication with the various devices comprising the data processing system. Communication between the control processor and the data processing system devices occurs on a separate maintenance and diagnostic bus. The control processor initiates diagnostics stored within several of the data processing system devices. The self-diagnosing devices provide an indication to the control processor of successful completion of the diagnostic stored therein. The device being diagnosed and the control processor operate asynchronously of each other and utilize a register bit to indicate successful completion of the diagnostic test.

Abstract: A laser structure for generating white laser light when energized by a source of dc voltage. The laser tube structure comprises a gas-filled envelope having a longitudinal axis, an anode electrode forming a portion of the envelope. A hollow cathode is positioned within the envelope and coaxially disposed with respect to the anode electrode portion of the envelope. Members are coaxially aligned with the ends of the envelope such that a structure is provided for confining a gaseous medium therein, a dc voltage applied between the cathode and anode electrode creating a discharge therebetween, the discharge stimulating continuous wave laser emission along the longitudinal axis of the cathode, the laser emission comprising simultaneous multi-line emissions in the form of white light.

Abstract: Apparatus for generating a velocity command signal representing a predetermined optimum velocity of movement of a selected one of a plurality of movable elements from its actual position to a desired stopping position. The apparatus comprises means responsive to a first signal representative of the distance to be traveled by the selected movable element from its actual position to a desired stopping position for generating a second signal proportional to a predetermined optimum velocity of movement for each of the plurality of movable elements when required to be moved a distance represented by the first signal.

Abstract: During the reading of certain combinations of bits from a magnetic disk memory surface, wider than normal separations may occur between positive and negative peaks. In order to eliminate false peak readings to be decoded by the decoding circuitry, a delayed readback signal is compared with the undelayed signal in a pair of polarity discriminators. The delayed signal is also differentiated to provide a complementary output. Zero crossing detectors are connected to receive the complementary outputs and are gated by the polarity discriminators. The output of the detectors is connected to a latch circuit which sets and resets according to zero crossing detections. An output circuit develops a peak indicating pulse whenever the latch changes state, which is utilized by subsequent circuitry to generate the decoded digital signal.

Abstract: A light focus sensor having first and second grids comprised of interlaced light transmissive and light reflective portions and a rotating optical modulator comprised of a plurality of alternate light transparent and light opaque portions. The modulator portions are half the size of the reflective portions of the grids and the modulator is positioned in relation to the grids such that the phase relationship between the portions of one grid and the portions of the modulator is 180.degree. different than the phase relationship between the portions of the other grid and the portions of the modulator such that the composite signal passing through the modulator is indicative of the directional movement required to achieve focus.

Abstract: A scanning system is provided which uses directed light from a scanning element, which directed light is reflected from a curved reflective surface for scanning across a medium with a planar object surface. The scanning element includes a planar reflective facet, such as the planar mirrored surface of a galvanometer, which scans the light across the curved reflective surface in a direction normal to its axis of curvature. To provide a linear focal line, the planar surface is tilted from its optical axis by a first angle and is off-set for rotation about an axis at a second angle from an optical axis orthogonal to the optical axis of the curved surface.

Abstract: Method and apparatus for moving a plurality of transducer heads to and from an operative position adjacent the magnetic surfaces of a plurality of rotating disks in a magnetic disk storage system. The transducer heads are supported on a "T" Bar attached to a carriage. The transducer heads are loaded or urged towards their respective disk surfaces in pairs of one up (left) and one down (right) or one down (left) and one up (right) by means of a torsion bar. A like plurality of camming elements are mechanically linked with the carriage and are movable radially with the elongated supports to restrain the heads from contact with the disk surfaces until a loading position is reached substantially inward of the circumferences of the disks, after which the camming elements are moved to a withdrawn position and held there by a solenoid-operated latch, thereby allowing the transducer heads to be moved to any desired radial position.

At the receiving end the missing bits are filled in by an interpolation device according to the data in the vertically adjacent bits or the horizontally adjacent bits.

Abstract: A tire designed for operation both as a pneumatic tire under ordinary conditions, and also without inflation under emergency conditions, has thick sidewalls made of low-hysteresis high-modulus vulcanized natural rubber composition containing reinforcing carbon black and also containing an effective anti-oxidant, together with a cobalt soap to prevent reduction in modulus during service of the tire.
