Abstract: COMBINED FAILSAFE AND SERVICE BRAKE          Abstract of the Disclosure A hydraulic or fluid-power brake is disclosed,  The brake comprises a stationary housing, and a rotor shaft jour-naled in the housing.  A number of rotor discs are carried on the shaft for rotation therewith, but they are adapted for axial sliding motion on the shaft, as by a spline arrangement.  A num-ber of stator discs are interleaved with the rotor discs and are carried on torque pins mounted in the housing for sliding motion in the direction of the rotor shaft axis, but are secured against rotational movement with the rotor shaft and rotor discs.  Bias-ing means such as springs urge the stator discs into braking engagement with the rotor discs.  To relieve this braking action and permit free shaft rotation, a primary piston, having an annular skirt surrounding the rotor discs, engages one stator disc to apply a force urging that stator disc in a direction opposite to the force applied by the biasing means so as to re-lease the braking action.  A secondary device is included for opposing the primary piston action so as to permit the biasing means to urge the stator discs into braking engagement with the rotor discs.  This secondary means can be independently energized, by fluid pressure or mechanical means as by a service brake.  In one embodiment, this secondary means includes a piston carried in an annular cylinder chamber; the piston is located to apply an annular force against the stator disc in opposition to the force applied by the primary piston.

Abstract: A B S T R A C T            A belting with a single-layer central portion and two tubular edge portions is made on a needle ribbon weav-ing machine. One of the tubular edge portions is woven as single layer and then closed to form the tubular edge portion by pull on the weft thread. A knitting course which keeps this tubular edge portion closed is made by means of a tuck and/or interlocking thread in such a way that it disappears in the fabric and does not project therefrom. This is achieved either by feeding more tuck thread as usual so that tuck thread loops are drawn by the weft thread from the knitting course into the fabric or by utilizing no tuck thread but only an interlocking thread in making this tubular edge but lay-ing it into the head of the knitting needle from above.

Abstract: OXYGEN SENSOR CONTROL SYSTEM     Abstract of the Disclosure An air-to-fuel ratio control mechanism in an internal combustion engine operates in partial response to the output of a control circuit, which circuit in turn is responsive to the out-put of an oxygen sensor mounted in the exhaust of the engine.          The control circuit biases the control mechanism toward a pre-determined desired air-to-fuel ratio, normally at or near stoichiometric.  When the sensor output deviates above a first predetermined value or below a second predetermined value for longer than a predetermined time period, a comparator circuit provides a disabling signal which disconnects the control circuit from the air-to-fuel ratio control mechanism.  At the same time, the disabling signal connects a predetermined signal to the air-to-fuel ratio control mechanism.  This predetermined signal simulates a nominal control circuit output to maintain the air-to-fuel ratio close to stoichiometric or some other preferred setting such as a air/fuel ratio which is lean.  An indicator is turned on by the disabling signal to alert the operator to pos-sible malfunction.

Abstract: MECHANICAL SEAL ASSEMBLY            Abstract:    A balanced mechanical seal between two zones having different fluids, at least one of which may be corrosive, abrasive, of different lubricity, of elevated temperature and with other undesirable properties or char-acteristics.  A buffer fluid is introduced into one zone at a constant rate so as to flow to a location (68) radially inwardly of contacting seal faces (34,70) and then radially outwardly of said seal faces. The flow serves to cool and lubricate the seal faces and substantially prevent the flow of fluid from the other of the zones radially inwardly across the seal faces.  The ratio of areas which determines the seal balance is such that in the direction of buffer fluid flow it is of relatively low value. However, in the opposite direction of fluid flow, the balance is a much higher value.  Thus in the event of buffer fluid failure, flow of the undesirable fluid across the seal faces is substantially prevented, thus preserving the faces from substantial damage from m that undesirable fluid.

Abstract: ABSTRACT OF THE DISCLOSURE     An improved filmstrip-carrying cassette, the film-strip carrying thereon microimages arranged in rows and col-umns, and a viewer for illuminating, projecting, enlarging and reading on a display screen a selected one of the micro-images is provided, using a pair of transparent plates to engage a selected portion of the filmstrip on opposite sides to hold same in a precise focal plane for properly illuminating and projecting the selected microimage.  The filmstrip has great width to accommodate multiple rows of microimages, and motor means operate to transport the filmstrip selectively in oppo-site directions to quickly locate the column in which the de-sired microimage is located.  The cassette is carried by a viewer-mounted carriage that is manually reciprocable along a track, so as to traverse the column in seeking the desired microimage.  The transparent plates are separated simultane-ously with the energizing of the motor means to permit unfet-tered movement of the filmstrip.  In one form of construction, the transparent plates are carried by the cassette.  In a pre-ferred form, the cassette carries one transparent plate, and the other plate is carried by the viewer's carriage; the motor means provides selectively fast or slow transport, and the trans-parent  plates  are  caused to separate only during fast trans-port, to provide visual coordination for locating the selected microimage with the slow transport of the filmstrip.  A modular construction for the light projecting portion of the viewer provides for simplicity of adjustment and servicing.

Abstract: ABSTRACT OF THE DISCLOSURE        The clock generator, which is shown as being a part of a data processor, includes a recirculating shift register and gate combination for deriving a set of four clock phase signals from a master clock signal. The generator also includes two gates and a D flop which form sequential circuitry. The latter controls the shift register to im-part a desired non symmetry to the clock signals, and to vary that symmetry, as necessary to minimize the clock cycle time and to maximize the processor operating speed. To this end, the circuitry normally makes the clock pulse widths a minimum, consistent with the processor require-ments, and, on demand, doubles the widths of only those clock pulses which are actually timing the slowest processor portion, thereby lengthening only those specific clock cycles which contain the demanded widened clock pulses.
