Title: Closing and injection valve
Inventor: ALBRIGTSEN ROLF H
IPC: F16K31/122
Filed: 1987-12-09
Granted: 1991-12-24
Abstract: ABSTRACT            A valve for shutting off or closing a main fluid flow com-prises a valve stem (28) having a valve head (48), which may engage a valve seat (18). At the end remote from the valve head the valve stem carries a piston (36), which can be actuated by a closing fluid to shut off the main fluid flow. The valve is characterized in that the valve stem (28) is hollow and at the end at which the valve head (48) is provided, is open, and at the opposite end has openings (46) opening into the interior of the hollow valve stem (28), and that the piston (36) is mounted for axial movement on the valve stem (28) to allow further movement towards the valve seat (18) against spring action when the valve head (48) has engaged the valve seat (18) and the valve stem (28) has therefore come to a halt, said further movement relative to the valve stem (28) opening a passage (45) into the openings (46) in the valve stem (28), whereby closing fluid will be injected into the main flow passage (32) through the valve stem. The valve can be used for hot gas defrosting of an evaporator with automatic circulation in a freezing or cooling installation comprising also a compressor (3), a condenser (4) and a liquid separator (2), the valve (9) being connected into a return flow passage (8) from the evaporator (1) to the liquid separator (2). The valve (9) can then periodically close the main fluid flow through the return flow passage and inject hot gas into the evaporator (1) for defrosting purposes. Hot gas from the pressure side of the compressor (3) is used to effect the closing. A closing of the main fluid flow in the return passage (8) and an injection of hot gas in the opposite direction is thereby obtained by means of one and the same valve, merely by opening the hot gas supply.

Title: Fascia panel structures
Inventor: DEMPSEY WILLIAM F
IPC: E04F13/08
Filed: 1988-06-13
Granted: 1992-03-03
Abstract: Abstract of the Disclosure The invention provides a new fascia panel structure consisting  of  a  plurality  of  butting  panels  disposed side-by-side on a support structure fastened to the building to  which  the  fascia  is  applied.   The  support  structure consists of two vertically-spaced horizontal parallel rails having  upwardly  opening  channels.   The  panels  each  have downwardly extending horizontal top and bottom edges which engage in the channels and can slide sideways therein.  Each panel  has  a  channel-forming  member  fastened  to  its  rear surface  adjacent  one  vertical  edge,  and  a  tongue-forming member  fastened  to  the  rear  surface  adjacent  the  other vertical  edge;  these can also  act  as  stiffening members.          The panels are installed on the horizontal  rails and slid sideways until the respecitive panel  tongue is engaged in the adjacent panel channel, the tongue covering any wall gap that may be left to accomodate expansion.   The panels are held in place by an elongated horizontal hold-down cap strip that  is  fastened  to  the  building  and  engages  their  top edges.   The panels are  therefore  "free-floating" on their support  structure  to  avoid  distortion  with  changes  in ambient   temperature,    and   consequent    buckling    and "oil-canning".   The  preferred material  for  the  panels  is sheet  aluminum,  or  its  alloys,  and  preferably  the  other members are of extruded aluminum, or its alloys.  Preferably the members are fastened to the rear faces of the panels by glueing, using double-sided adhesive tape.

Granted: 1991-04-30
Abstract: IMPROVED GAS DISPERSION PROCESS AND SYSTEM               Abstract of the Invention Gas dispersion in a liquid is enhanced by combining the gas and liquid in close proximity to a venturi or other flow constriction means used to create supersonic flow velocities and subsequent deacceleration to sub-sonic velocity.  When a venturi is employed, the gas-liquid mixing occurs in the converging portion of the venturi or upstream but in close proximity to said venturi. Turbulent flow conditions upstream of the venturi or other flow constriction means adequate to disperse the gas uniformly in the liquid are not required and, surprisingly, the gas and liquid need not be uniformly dispersed prior to acceleration to supersonic velocity.
