Abstract: PRESSURE RELIEF VALVE                     (Abstract of the Disclosure) A pressure relief valve includes a valve body having an axial inlet port and a lateral outlet port, with an enlarged bore extending between such ports.  A valve bonnet attached to the valve body slidably guides a poppet for movement between closed and open positions for closing and opening the inlet port.  A seal ring positioned in the bore adjacent the inlet port sealingly surrounds the poppet in its closed position. The seal ring is axially compressed between a retainer ring and a backup surface, and a ring nut threaded in the bore compressively engages the retainer ring.  The ring nut is located entirely on the inlet port side of the outlet port so it does not inhibit flow to the outlet port when the poppet is open.  A poppet guide bore in the bonnet extends inwardly from a bonnet end surface, and a pair of concentric recesses of different diameters also extend into the bonnet from the end surface.  One recess receives a seal ring positioned in surrounding sealing relationship with the poppet, and the other recess receives a push-in retainer for retaining the seal ring in its recess.  A small diameter stem on the poppet extends into a bonnet spring receiving bore and has a rounded end received by a conical recess in a guide disc.  Close fitting cylindrical locating surfaces are used for providing accurate concentricity between the bonnet and body, and between the retainer ring and the bore.

Abstract: APPLICATION OF JOSEPH P. CARMODY        CONTROL SYSTEM FOR A SELECTIVELY CONFIGURABLE             MACHINE CONTROL PANEL               ABSTRACT A machine control panel includes a matrix of pressure sensitive switches and a matrix of light emitting indicators, e.g., light emitting diodes (LED's) in a substantially coplanar array.  An aperture array formed by a flexible cover sheet having an opaque coating surrounding a matrix of transparent apertures is positioned on top of the LED and switch array with corresponding ones of the LED's and apertures in alignment.  Unused apertures in the aperture matrix corresponding to unused LED's are selectively closed by opaque aperture covers.  Switch identifying covers in the form of labels are positioned on top of the aperture array to visually indicate selected ones of the switches. Switches with associated LED's have switch identifiers with transparent apertures aligned with selected ones of the LED's and open apertures in the aperture array. Additional opaque display elements and system interconnections are appropriately placed on the aperture array to form a desired machine control panel layout.  A flexible transparent overlay located on top of the aperture array may be used to protect the labels and aperture covers while enabling a switch operating pressure to be transferred to the switches. Additionally, an enclosure can be provided as a protective housing for the machine control panel and as a means for enabling the panel to be mounted in an operative orientation on a suitable support associated with a machine to be controlled.  A selectively configurable control system is connected to the LED and switch array to recognize only switch actuation inputs from preselected valid switches, e.g., those identified by labels, and, in turn, to energize only desired LED's e.g., those associated with actuated valid switches.  Thus, the configurable control system is used to transfer the valid switch operation to the controlled machine while providing an LED indication on the machine control panel of valid switch actuation and associated machine system operation.

Abstract: Abstract of the Disclosure A phased-overmoded, tapered waveguide transition has a central section which is tapered linearly in the longitudinal direction and two end sections which are tapered curvilinearly in the longitudinal direction. One of the end sections and at least a portion of the other end section are overmoded and, therefore, give rise to higher order modes of the desired microwave signals propagated therethrough.  The linearly tapered central section shifts the phase of higher order modes generated at one end of the transition so that at least a major portion of such higher order modes is cancelled by higher order modes generated at the other end of the transition.

When a cage other than the cage for which the destination call is automatically registered, has arrived at the floor where said destination buttons are manipulated, the destination call is also registered even for this non-allotted cage.          Therefore, whichever cage the passengers are on board, they are brought to their desired floors without the need of registering again the calls in the cage.

Abstract: ABSTRACT     A cast, low density metal disk for anti-skid devices which has a periphery of sufficiently small width that when it contacts the wet side wall of a tire on a vehicle it spreads the film of water to each side and leaves an es-sentially dry area of contact between the disk and the tire instead of hydroplaning on it.  The periphery preferably is covered with an anti skid material, e.g., rubber.  Chains are pre-turned or twisted in the same direction a tire tends to turn them when rolling over them to avoid further twisting with consequent shortening in use and they are given a non-circular, e.g., square cross section to increase their anti-skid properties.  The chains are welded at one end to a steel ring which is removably fastened to the under surface of a disk by bolts.

Abstract: TITLE          Bearing Fail-Safe Device ABSTRACT OF THE DISCLOSURE   A fail-safe device for preventing undesired rotation of the output as the result of bearing failure and seizure is shown according to the teachings of the pre-sent invention in its most preferred form for use with a clutch engagable in a single driving position.  In its most preferred form, the output includes a hub portion which is rotatably mounted to the input of the clutch by a bearing.  The output of the clutch further includes a collar portion for receipt upon the hub portion and forming a break away connection therebetween.  The driven portion of selectively rotationally interrelating members of the clutch, i.e., teeth in the preferred embodiment shown, is located on the collar portion of the output.          Under normal operation and without bearing failure, the collar and hub portions of the output have the same rela-tive rotational position and rotate as a single unit.          However, in the event of bearing failure and seizure and assuming the output is not clutched in with the input, relative rotation is allowed between the hub portion and the collar portion of the output to prevent undesired rotation of the machinery or other apparatus connected to the output of the clutch.
