Granted: 1991-07-16
Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to a fixed munition for a grenade launcher with a plastic case, a projectile having a tracer and/or delay element, as well as a primer charge and a propellant charge, both of which are accommodated in a cup at the base of the case.  In order to provide reproducible results during shooting, care has been taken to ensure that, despite very varied environ-mental conditions, it is always possible to keep to an almost constant muzzle velocity.  While retaining ease of assembly of the munition, this has been achieved in that the cup that accommodates the primer charge and the propellant charge consists of two con-centric cases, the inner case being supported in the outer case such that it can slide and telescope therewithin.  The outer case has an external thread at its free end, with an annular break point that is contiguous to this thread.  The base of the projec-tile incorporates a case that has an internal threaded portion, and this can be screwed onto the outer case of the cup.  An advantage is that dependable ignition of the tracer and/or delay element is achieved in that a flame channel that leads to the tracer and/or delay element is incorporated in the base of the cup-shaped inner case.

Abstract: METERING VALVE Abstract of the Disclosure A valve for delivering a metered flow of liquid for flushing of a plumbing fixture or the like includes inlet and outlet ports and a main valve con-trolling flow from the inlet to the outlet port.  A control chamber is in pressure communication with the main valve and a restricted flow path from the inlet port to the control chamber increases the control pressure to hold the main valve closed in a standby condition.  A pilot valve is opened by an actuator to reduce control pressure and initiate a cycle of opera-tion of the main valve.  A snap acting mechanism is movable between two stable positions for opening and closing the pilot valve.  The actuator is capable of operating the snap acting mechanism for opening the pilot valve but not for closing the pilot valve.  The main valve in its fully opened position closes the pilot valve regardless of the position of the actuator.

Title: Dryer differential pressure controller
Inventor: FOSLER ROBERT C
IPC: F26B13/18
Filed: 1987-01-07
Granted: 1991-01-15
Abstract: DRYER DIFFERENTIAL PRESSURE CONTROLLER      ABSTRACT OF THE DISCLOSURE      A control apparatus for controlling the differential pressure between steam inlet and outlet lines of a web dryer and includes a selectively controllable outlet valve disposed in the outlet line for selectively controlling the flow of blow-through steam, condensate and non-condensible gases out of the dryer.  A dryer speed sensor generates a first control sig-nal and a condensing rate sensor senses the rate at which a layer of condensate builds up within the dryer.  The condensate rate sensor generates a second control signal.  A control device is operably connected to an outlet valve actuator for selectively energizing the actuator in response to the first and second control signals.  The control device compares the signals to determine the optimum relative setting of the outlet valve so that flooding of the dryer with condensate is inhib-ited while the differential pressure between the inlet and outlet lines is maintained as low as possible.

Title: Pressure signal instrumentation having removable flanges and mounting method therefor
Inventor: NIMBERGER SPENCER M
IPC: B21D53/00
Filed: 1987-01-23
Granted: 1991-09-03
Abstract: PRESSURE SIGNAL INSTRUMENTATION HAVING REMOVABLE FLANGES AND MOUNTING METHOD THEREFOR     ABSTRACT OF THE DISCLOSURE  An instrument manifold and pressure transducer are provided for detecting a pressure differential across an orifice fitting.  Removable flanges are utilized on the output side of the orifice fitting, and on the input and the output ends of the manifold.  Each flange may be structurally secured to its respective piece of equipment by special nipples, and is provided with apertures for receiving bolts to interconnect the flanges and the equipment.  The versatility of the equipment is substantially increased, the response time and signal reliability is increased, and the installation costs are reduced.

Title: Hydrogenation catalyst shapes
Inventor: POPPELSDORF FEDOR
IPC: C07C27/00
Filed: 1987-03-05
Granted: 1991-05-28
Abstract: ABSTRACT OF THE DISCLOSURE      An  improved  calcined  hydrogenation  catalyst shape  which  is  useful  for  the  catalysis  of hydrogenation  reactions  in  a  tubular  reactor  is provided.  The  catalyst  shape has  an  annular configuration with an open center core, and wherein the  shape  contains,  as  a  reinforcing  matrix distributed therein,  up to about 50 per cent  by weight  of  milled  glass  fibers  having  specific dimensions  and  wherein  the  crush  strength  of  the shape  is vastly  improved  with  little  change  in catalytic activity over the non-reinforced shape of comparable size. Additionally, when the shapes of the  present  invention  are  employed  pressure-drop and diffusion problems are reduced.  The catalyst shapes   are    particularly    useful    for    the hydrogenation of alkyl oxalates to ethylene glycol whereby  the  reaction  can  be  conducted  at  lower temperatures  and  hence by-product  formation  is minimized.
