Abstract: Case 256 Abstract of the Disclosure A "fire-safe" packing arrangement (104) for a valve stem (72) which extends through a packing chamber in a valve bonnet bore (42) to a valve chamber (50) in a valve body (12). The packing arrangement (104) comprises a low temperature packing assembly (112) positioned within the packing chamber between the stem ((72) and the wall of the bonnet bore (42) for sealing therebetween at normal temperatures and resting on an inner an-nular shoulder (62) provided in the bonnet bore (42). A metal spacer ring (116) is positioned within the packing chamber axially outward of the low temperature packing assembly (112) with respect to the flow passage (18, 20) through the valve. The spacer ring 116 has a lower side or inner end (140) thereof resting on the low temperature packing assembly (112). The packing arrangement includes a high temperature packing assembly (114) positioned within the 'packing chamber between the stem (72) and the wall of the bonnet bore (42) and axially outward of the spacer ring (116) with respect to the flow passage (18, 20), The high temperature packing assembly 114 is sand-wiched between the outer end portion (138) of the spacer ring (116) and a retainer (106) seated on an annular shoulder (58) provided in the bonnet bore (42). The high temperature packing seals between the stem (72) and the valve body (12) at above normal temperature conditions of the valve body (12) which are destructive of the low temperature packing assembly (112). The packing arrangement (104) effectively seals throughout the range of low and above normal temperatures without imposing frictional drag on the valve stem,

Abstract: SEEDLING PROPAGATING CONTAINER AND METHOD                ABSTRACT OF THE DISCLOSURE           A seedling growing container is illustrated wherein a number of removable partitions or barriers are positioned together in a block.  Each of the partitions has interconnected diverging walls forming a series of troughs therebetween open at the top and the bottom so that the partitions may be placed in opposing relation as in a tray forming growing compartments from each of the opposing troughs which are in register with each other, suitable for growing a single seedling.  Positioning of the plugs is contemplated such that alternate rows of plugs of growing material, each of which is capable of growing a single seedling, are utilized so that each plug will be surrounded for the most part by a partition with the remainder being surrounded by an air space for preventing roots from growing from one plug to the other through the process of air pruning.          The tray is partially open at the bottom, at least to an extent sufficient to provide an opening for heated air to be passed upwardly through the voids formed by the omitted plugs for further encouraging growth of the seedlings.  Any suitable means may be utilized for positioning the partition together to form a block.

Abstract: DRAINAGE DEVICE WITH      FLOW METER       ABSTRACT     A drainage device is provided with a collection chamber, an underwater seal chamber, and a separate flow chamber.  The underwater seal chamber which prevents the flow of atmospheric air from the device into the pleural cavity of the patient is formed by a recessed portion in a partition separating the un-derwater seal chamber from the collection chamber.  A passage-way from the underwater seal chamber into the collection chamber is located in the partition separating the chambers and a baffle is formed around the opening to prevent excessive loss of fluid from the underwater seal chamber into the collection chamber when the device is inadvertently tilted.  The flow chamber is closed off from the collection chamber and is connected with the underwater seal chamber by means of a tubular passageway adjacent the upper wall of the drainage apparatus so as to prevent fluid from passing from the underwater seal chamber into the outlet passageway. An air flow meter is provided in the flow chamber to measure the rate of air flowthrough the flow chamber.

Abstract: ABSTRACT OF THE DISCLOSURE         A DEH (digital electrohydraulic) control system for a steam turbine generator having a steam bypass system.          The turbine system includes a high pressure turbine having throttle and governor steam admission valves as well as an intermediate pressure turbine having stop and interceptor steam admission valves.  The turbine is brought on line by initially controlling steam admission into the intermedi-ate pressure turbine by modulating the interceptor valve in response to a speed error signal generated as a result of  the  difference  between  actual  and  a  predetermined reference speed.  During this initial control the throttle valve  remains  in a  closed position.  When the  turbine speed has attained a preset value such as half of synchron-ous speed, the interceptor valve is held at the same posi-tion it was in when the preset speed was attained and the throttle valve is controllably open in response to the same speed error signal.  After a preset transfer speed has been attained, control of steam admission to the high pressure turbine is transferred to the governor valve and after synchronous speed has been reached the DEH system switches to a load control mode wherein the signal which controls the positioning of the governor valve is also utilized to control the interceptor valve position.  The interceptor valve thereafter will reach a wide open posi-tion at a predetermined load.         During the speed control mode of operation the control  signal  which  controls  the  positioning  of  the interceptor valve is modified by certain pressure condi-tions  at  the  input of the interceptor valve after the preset speed is attained.

Abstract: ABSTRACT                     CALL INTERCEPTOR   Automatic telephone answering equipment is disclosed which is associated with a telephone set connected to a switching system along with other telephone sets, and the answering equipment functions with central message recording equipment which is also connected to the switching system.  Unanswered incoming calls originating from within or without the switching system are answered by the automatic answering equipment which then transfers the call to either another of the telephone sets or to the message recording equipment, as selected by the user of the answering equipment.  When the call is transferred to the central message recording equipment the identity of the telephone set to which the call was directed is forwarded to the recording equipment.  Only upon the calling party recording a message in the central message recording equipment, the recording equipment uses the called telephone set identity to call the originally called telephone set.  Upon the telephone answering equipment answering the call from the message recording equipment the recording equipment sends a signal which causes a message waiting visual indication to be provided at the answering equipment.  Thereafter, in response to the visual message waiting signal the message recording equipment may be called by the user of the telephone set and the recorded message is played back.

Abstract: ELECTRIC VACUUM CLEANER            ABSTRACT OF THE DICLOSURE           The electric vacuum cleaner here disclosed includes a main motor housing supporting a bypass type motor within it.  The motor housing is separably connected to and swingable about the materials collecting tank beneath it.  A tube projecting above the cover of the tank and extending laterally over the cover defines the air flow communication between the tank and depending side sections of the motor housing which meet and are releasably attached to the ends of the tube.  The tube also defines the swing axis of the motor housing.  Detents control this swinging.  A resilient cuff over the motor in the housing separates the fan motor bypass cooling air inlet and outlet from each other and from the main suction fan inlet, while also defining respective flow paths communicating with inlets and outlets from the motor housing.  A series of baffles between the main suction fan outlet and the outlet for this air from the motor housing elongates the path of this air, redirects it and damps its vibration for reducing noise.  An inlet airflow regulator selectively recirculates some of the air from the main fan outlet back to the main fan inlet which correspondingly adjusts inlet suction in the tank.  The bearings for the wheels under the tank at the air inlet support the wheels eccentrically on the bearings, whereby rotation of the orientations of the bearings adjusts the height of the air inlet.
