Abstract: PAPER ROLL WEB SPLICING           Abstract An elongated transverse paper preparation head is provided which has multiple sides. One side is exposed to the operator and the other two back sides form, with suitable guide members, a guide path for threading alternate leading edges of fresh web to the splicing nip area.  A spring bar holds the fresh web to an idler roll upstream of the nip.          The fresh web end section is laid across the exposed head side to which a vacuum is applied, and a double faced adhesive tape is applied along the edge portion's exposed face.  The edge is then cut off via a knife slot.  The fresh web end section is peeled from the exposed vacuumized side of the head and is manually fed along the guide path.  Positive air pressure is applied between the said head back side and the web to cause the web and the adhesive portion to be forced away from the head to eliminate interference therebetween.          The splicer nip roll axes are disposed in a common plane which has a bridging portion at the nip.  The nip roll for the fresh web is adapted to be driven and to have vacuum applied to its surface during said preparation.  The con-struction is such that the fresh web path from the holding spring, across the idler roll and the exposed head face to the knife cut-off slot is equal to the fresh web path from the holding spring, around the idler roll and through the guides to the nip.  During manual threading toward the nip, a loose loop is formed in the web.  When the leading edge of the fresh web approaches the driven nip roll, it is pulled thereonto by the vacuum and up to the said plane.  Braking stop bars are replaced by the said spring on one side and the adjacent idler roller on the other side.  The idler roller has a high friction surface thereon and has a high inertia due to its mass.  A high torque constant braking force is applied to the idler roller which causes the traveling expir-ing web to decelerate at a constant rate in a minimum controlled time interval.

Abstract: ABSTRACT   A door closure apparatus is provided for automatically closing a bifold door of a storage cabinet for combustible materials in the event of elevated temperatures.  A guide assembly hingedly mounted on the free end of the folding door includes guide fingers which ride along a guide path in a channel guide track at the top of the cabinet.  At one end of the track there is mounted a bracket slidably carrying a latch member movable between a latching condition in the guide path and a release condition out of the guide path.  The latch member is normally held in its latching condition by a spring and fusible link combination which override a smaller spring urging the latch member toward its release condition.  Upon melting of the fusible link the latch member is moved to its release condition by the smaller spring.  The latch member is shaped to permit the guide member to cam past it as the door moves to its open position but prevents return movement of the guide member to hold the door in its open position.  The latch member may be manually operated.

Abstract: ABSTRACT      Two check valves in series with a zone between them are mounted between the supply pipe and discharge pipe, and a relief valve vents the zone to atmosphere under predetermined pressure conditions in the pipes.  A valve poppet in the upstream check valve has a pressure affected piston chamber and contains an ejector nozzle which dis-charges fluid when the valve is open.  The discharge passes through the zone and the velocity head is directed against a valve poppet in the downstream check valve. The action of the ejector nozzle aspirates the pressure affected chamber in the upstream check valve to reduce the pressure drop when the valve is open.  A valve poppet in the downstream check valve also includes a pressure affected piston area.  In each check valve the flow restriction across the valve seat decreases more rapidly than the downstream flow restriction.  Also, the outer surface of the valve poppet in the upstream check valve defines, with its stationamy barrel enclosure, a series of ribs and cavities which direct flow of fluid from the check valve through the ejector nozzle while minimizing flow into the aspirated chamber.  A relief valve device connected to vent the zone to atmosphere has a valve stem subjected to a pressume differential between the inlet pressure to the upstream check valve and the reduced pressure in its aspirated chamber.

Abstract: ABSTRACT OF THE DISCLOSURE           A combined chair and bed which can be utilized selectively as a chair and a bed comprises a frame assembly, a seat assembly including a back rest, a leg support and a seat hinged at one side edge to the back rest and at the oppo-site side edge to the leg support, and at least one link mechanism operable to set the combined chair and bed in selec-tive one of chair and bed modes.  While the seat assembly is mounted on the frame assembly through the link mechanism the link mechanism comprises a fulcrum about which the back rest pivots accompanied by an angular movement of the hinge between the back rest and the seat about the same fulcrum, thereby shifting the seat selectively upwardly and downwardly depending upon the direction of the pivotal movement of the back rest and a pair of links which, when the back rest is moved to the laid-down position, are erected to support the seat in flush with any one of the back rest and the leg sup-port.  A transmission system for transmitting the movement of the back rest to the leg support is also included.

Abstract: ABSTRACT          The invention relates to an optical terminating set for time-modulated optical transmission signals.  The problem of crosswalk attenuation of the ter-minating set specific for these signals is solved by concentrically coupling a first glass fibre to a second glass fibre with a cross section of the first light guide smaller than a cross section of the second light guide in the coupling area.  The signal emerging in the difference area from the glass fibre with larger core diameter is supplied to a detector either via a mirror or directly.

Abstract: FAIL-SAFE STOP ARRANGEMENT FOR   CRANE BOOM EXTENSION CABLE     Abstract of the Disclosure -A pair of safety stop blocks are welded to opposite sides of the fly section of a construction crane boom.  The stop blocks have slide passages to receive the branches of a boom extension or load cable which is looped around an arcuate saddle near the base of the fly section.  A pair of stop buttons are swaged to the extension cable branches between the saddle and the two stop blocks and are normally spaced somewhat from the stop blocks to allow the cable to seek an equal loading position around the saddle.  The stop blocks carry cable retainer elements near the tops of the slide passages to prevent the escape of the cable therefrom.  Should the extension cable fail in any region thereof under load, at least one swaged stop button will be en-gaged by a stop block of the boom fly section to positively arrest its retractive movement before any damage can occur.

Abstract: BRAKE SYSTEM WARNING CIRCUIT ABSTRACT OF THE DISCLOSURE           A warning circuit which generates signals in response to selected conditions of a vehicle hydraulic brake system.  The brake system includes an engine-driven main source of hydraulic pressure, a relay-actuated auxiliary source of hydraulic pressure, a flow sensor for sensing the operation of the main source and a brake switch for coupling the auxiliary source with the battery in response to an operator brake application.  The warning circuit includes a first transistor switch coupled with a warning lamp, with the ignition switch and with the auxiliary source.  A second transistor switch is coupled to the ignition switch, to the auxiliary relay, to the flow sensor and to the first transistor switch.  A third transistor switch is coupled to the ignition switch, to the flow sensor and to the first transistor switch.  The system actuates the auxiliary source upon fail-ure of the main source during an operator brake application.  The warn-ing circuit generates a warning signal when the ignition switch is on during failure of the primary source independent of the application of the brakes and independent of the existence of an open circuit con-dition in the auxiliary source.  A warning signal is also generated in response to electrical open circuit conditions indicating failures of the various sensing components of the brake system.
