Abstract: A B S T R A C T           Disclosed is a device for indicating a change in the status of a matter to be checked, upon the occurrence of a specified event.  The device comprises a first plate adapted to be attached proximate a matter to be checked and having an outer surface and a second plate having an inner and outer surface, the outer surface bearing prominantly visible predetermined first indicia.  At least one of the first plate outer surface and the second plate inner surface has prede-termined second indicia.  The second plate is selectively movable relative to the first plate, so as to expose and make prominantly visible the second indicia and obscure the first indicia.  A particular embodiment provides a device for indicating that an adjoining room to the checker device has been checked in an emergency.  In the normal mode the second plate obscures the visibility of the first indicia.          After a room has been checked, the second plate is moved so as to expose the first indicia.  In the normal mode the second indicia is used to designate the nature of the dis-abilities of the occupants of a particular room.

Granted: 1985-10-01
Abstract: ABSTRACT     A fluid sampler is disclosed which operates so as to trap a liquid sample and then eject to. To achieve this, a piston (18) and sleeve (14) are displaced together downwardly to move a pair of port-holes (10, 11) in the piston out of register with a pair of ports (2, 3) in the sleeve wall to as to trap the liquid sample in an internal space in the piston interconnecting the two portholes (10, 11).  In this position the sleeve (14) is restrained against further downward movement.          On continuing downward advancement of the piston, the trapped liquid sample is ejected out of the internal space through a passageway (21) in the piston for analysis.         The sampler is ideally suited for taking oil sample from a pipeline and can be designed for isokinetic sampling.

Abstract: Abstract: Valve  converter/positioner  with  remote  feedback  and memory A  valve  positioning  mechanism,  configurable  as either a positioner or a converter, acts in response to a control signal supplied over a two-wire transmis-sion line by a remotely-located controller, and  pro-vides a feedback signal over the same two-wire line to the controller.  Depending on the configuration used, this feedback signal verifies either that the valve has assumed the position directed by the controller or that the actuating pressure to the valve is as directed by the controller.  The control signal triggers an elec-tropneumatic switch which initiates the flow of air to operate a pneumatic mechanism driving the valve stem. A variable inductor, its inductance value being depen-dent upon the valve position/actuating pressure, forms part  of an oscillator whose output  frequency varies with  the  inductance  value.   The  oscillator in  turn provides a measurement signal to the controller over the two-wire transmission line, the frequency of the signal  being  proportional  to  the  valve position/ actuating pressure.  The controller terminates adjust-ment of the valve when the measurement signal equals the controller setpoint.  Upon loss of power, the valve can be maintained at a pre-existing position, or,  in an optional  arrangement,  be returned to a  fail-safe condition, with or without a predetermined delay.

Abstract: IMPROVED SYSTEM FOR SENSING    SPATIAL COORDINATES          ABSTRACT OF THE DISCLOSURE         A system for sensing the spatial position of a moveable object with respect to an energized conductive surface whereby the spatial coordinates of the object are determined.  The system provides a means of accurately measuring the coordinates of the object with respect to a two-dimensional coordinate system independent of the third orthogonal dimension, thereby avoiding significant measurement errors due to variations of the object's position in the third orthogonal dimension.  The system also ascertains the coordinate position of the object in this third dimension, which can then be utilized as an indepen-dent control variable in the system.  Further, the system can accomodate a number of energized conductive surfaces over which the object may be positioned and can determine the spatial coordinates of the object with respect to any such surface.  In general, the system of the present invention can ascertain the generalized n-tuple position vector of the object with respect to each of a plurality of generalized, energized conductive surfaces.  In any of the foregoing forms, the energized conduc-tive surfaces can be transparent.

Abstract: ABSTRACT OF THE DISCLOSURE    An  improvement  in  a press  section  for a paper machine which includes at least four successive nips between which the web runs as a closed draw supported on a fabric or roll face.  A first fabric functions as a pick-up felt and to carry the web into the first dewatering press nip formed between a first pair of press rolls.  A second fabric carries the web from the first nip into the second nip whereupon  the web is detached from the second fabric to follow along with an upper roll of the second nip into the third nip formed between  the  upper  roll  of  the  second  nip  and  a smooth-faced roll.  A fourth nip is formed between the smooth-faced  roll  and  a  dewatering  press  roll.          Dewatering takes place through both faces of the web in the first nip, through only one face of the web in the second nip and in the fourth nip through the other face of the web in a direction opposite from the dewatering direction  in  the  second  nip.   The  third  nip  is  a substantially  non-dewatering  smoothing  and  transfer nip.  According to the invention, a belt felt runs over a sector of the upper roll of the second nip between and through the second and third nips.  The belt felt is  substantially  water  non-receiving  and  has  a smooth-faced outer  surface.   The web adheres to the belt felt after detachment from the second fabric and is carried into the third nip while supported on the belt felt.  After passing through the third nip, the web is detached from the belt felt at least in part due to  its  surface properties   and  adheres  to  the smooth-faced press roll on which it is carried into the next dewatering nip.

A hollow tubular carrier is disposed between and in abutment with these tubular extremities and the three members are secured, as by a bolt through them in the upper area where they are in abutment, and by an integral encircling element at their lower extremities, encircling element being pinned at externally diametri-cally opposite points of abutment of such element with the extremities of the tubular members.  The tubular carrier is orificed at selective intervals and receives an orificed tele-scoping foot member provided with at least one radially outwardly spring biased detent.  This detent serves to lock the foot member in any disposition relative to the carrier when the detent is passed through any registering orifices of the carrier and foot member.  The disposition of the foot member relative to this carrier may be changed by pressing the detent radially inwardly to where the foot member may then be slid upwardly or downwardly in relation to the carrier for redisposition and locking by the detent."

Abstract: CENTRIFUGAL PRESSURE COMPENSATOR FOR A                 VARIABLE DRIVE PULLEY            Abstract of the Disclosure A pressure compensating mechanism for a dual control piston variable drive pulley has a central chamber disposed between the control pistons.  The central chamber is filled with fluid from one of the control passages and is open to exhaust through a controlled restriction.  The fluid in the central chamber increases in pressure with increased rotational speed of the pulley to compensate for the centrifugal pressure buildup on one of the control pistons.  The controlled restriction establishes the base pressure in the central chamber so that the resultant pressure in the central chamber compensates for centrifugal forces in excess of the centrifugal effect on one of the control pistons thereby compensating, at least partially, for the centrifugal pressure effect on the other of the control piston.
