Title: Power unit for converting heat to power
Inventor: EDWARDS THOMAS C
IPC: F01K13/00
Filed: 1986-12-02
Granted: 1991-03-05
Abstract: Abstract:      A transportable, frame mounted power unit for converting heat from a low-grade energy source to electric power.  Heat from a source is supplied to the power unit in the form of hot fluid circulated through a heat exchanger associated with a boiler. Liquid refrigerant in the boiler is vaporized and passes through the stages of an organic Rankine cycle, the expansion stage being carried out in a rotary, positive displacement expander.  The con-densing stage is carried out in a condenser asso-ciated with a cold heat exchanger which is connected to a supply of cooling fluid through cooling lines. The output shaft of the expander is connected to drive an electric power generator and individual fluid feed pumps for returning liquid refrigerant from the condenser to the boiler and for circulating hot and cold fluids through the hot and cold heat exchangers, respectively.  Driving all the fluid feed pumps from the expander output shaft permits flow matching between refrigerant circulating between the boiler and condenser and fluid circulating through the hot and cold heat exchange circuits.

Title: Boom operated demolition apparatus and method of breaking composite material
Inventor: KISTNER DAVID
IPC: B25D17/28
Filed: 1987-02-19
Granted: 1990-11-13
Abstract: Abstract of the Disclosure Boom Operated Demolition Apparatus and Method of Breaking Composite Material Demolition apparatus which is attached to a movable boom-like member of a machine.  The demolition apparatus includes support structure which carries a power plunger and an actuator plunger.  The plungers are mounted in adjacent relationship and are movable with respect to the support structure.  A compression spring urges the power plunger in a direction from the support structure.  The actuator plunger includes a latch device which engages a portion of the power plunger.  In operation, the support structure is moved toward a surface to be demolished.  The actuator member engages the surface and remains fixed as the support structure continues to move toward the surface. Therefore, as this occurs, there is relative movement between the support structure and the actuator plunger.  A latch carried by the actuator plunger engages a part of the power plunger and retains the position of the power plunger with respect to the actuator plunger.  Therefore, movement of the support structure toward the surface is opposed by the spring, and compression forces of the spring increase as such movement occurs.  As the support structure is moved toward the surface, an abutment member carried by the support structure engages the latch and releases the latch from engagement with the power plunger.  Thus, the power plunger is released for rapid movement by the spring, and the power plunger strikes the surface for demolition thereof.

Title: Water mixer tap, of the single-lever type
Inventor: STELLA PIETRO
IPC: F16K11/074
Filed: 1987-07-22
Granted: 1990-11-20
Abstract: ABSTRACT OF THE DISCLOSURE The  water  mixer  tap   comprises a  body  defining  a dispenser  chamber  connected  to  a  dispenser  conduit.  A movable shutter disc is provided  in the mixing chamber, and is  operable by means of an external lever and acts  on  two seats,  respectively  communicating  to  a hot  water  inlet conduit and to a cold water inlet conduit.  The movable disc defines at least one seat control port which leads into  the mixing  chamber. The peculiarity of the invention resides in the  fact that the control port defines useful flow sections for the water which are variable along planes  substantially perpendicular  to the plane of contact between the seats and said movable shutter disc.

Title: Air perimeter seal for opening
Inventor: FROMMELT JOHN A
IPC: E04B1/34
Filed: 1988-03-09
Granted: 1992-09-22
Abstract: Abstract of the Disclosure A seal disposed about the periphery of an opening such as a warehouse door includes an inflatable head bag and a pair of facing inflatable side bags.  The head and side bags are each comprised of a plurality of serially coupled, elongated, aligned pleated sections which are separated by apertured baffles for regulating air flow between adjacent pleated sections.  A source of air under pressure such as a blower directs air into an upper head bag which, in turn, directs the air flow into the facing side bags via respective duct arrangements coupling the head bag to the side bags.  Under pressure, the head and side bags expand toward the center of the opening to enclose in a sealed manner an object such as a loading vehicle positioned within the opening.  Disposed within and along the width of each of the side bags are a plurality of spaced horizontal ropes or straps which are coupled at a first end thereof via an alignment tube to the nose edge of the end, or distal, pleated bag section, and at a second end thereof to vertically movable weights which bias the side bags to the retracted or open position when air under pressure is no longer provided to the side bags.  A plurality of spaced vertical retraction straps in the head bag are wrapped around a spring-biased roller tube positioned in an upper portion of a support frame and extending across the opening for rolling the head bag up in a retracted position when air under pressure is no longer delivered to the perimeter seal.

Abstract: ELECTROLYTIC CELL STACK WITH MOLTEN     ELECTROLYTE MIGRATION CONTROL                       ABSTRACT    An electrolytic cell stack includes inactive electrolyte reservoirs at the upper and lower end portions thereof.  The reservoirs are separated from the stack of the complete cells by impermeable, electrically conductive separators.  Reservoirs at the negative end are intitially low in electrolyte and the reservoirs at the positive end are high in electrolyte fill.  During stack operation electrolyte migration from the positive to the negative end will be offset by the inactive reservoir capacity.  In combination with the inactive reservoirs, a sealing member of high porosity and low electrolyte retention is employed to limit the electrolyte migration rate.

Abstract: A  hydrotreating  catalyst  is  described  which comprises  at  least  one Group VI metal, metal oxide, or metal  sulfide,  and at least one Group VIII metal, metal oxide,  or  metal sulfide, supported on a carrier wherein (A)  the  catalyst  comprises from about 10% to about 35% by  weight of combined metal, and the atomic ratio of the Group  VIII  metal  to  Group VI metal is in the range of from  about 0.5:1 to about 2:1; (B) the carrier comprises from  about  0.5  to  about 10 weight percent of halogen, from  about  0.5 to about 5% by weight of silica and from about  85  to  about 99% of alumina; and (C) the catalyst is  characterized  as having a median pore radius of from about  30  to about  65 Angstroms, and a surface area of from  about  120  to  about 180 m2/g.  Also described are novel  and  improved procedures for preparing the carrier or  support  used to prepare the catalysts.  The catalyst is  useful  in  the  production  of lubricating oils from crude  hydrocarbon  oil  stocks in that the hydrotreating process  results in the formation of oils having increas-ed   viscosity  indexes,  reduced  aromatic  content  and improved  stability.  The nitrogen and sulfur contents of the  oils  also are reduced through the use of the catal-yst in the hydrogenation process.
