Title: Labeling and liquid plastic coating system for bottle-like objects
Inventor: SCHMELZER STEPHAN
IPC: B65C9/22
Filed: 1991-04-17
Granted: 1995-02-07
Abstract: The invention is used in a labeling machine for applying liquid to the surface of the bottles af-ter the labels are applied for the purpose of render-ing scratches, abrasions, chipping and chafing of the bottle surfaces invisible.  To minimize the space tak-en by the combination of the labeling machine and the new liquid applicator device, the device is associated with the outfeed starwheel of the labeling machine. The liquid applicator device includes a fixed arcuate friction and applicator surface on which the bottles roll  by  reason  of  being  orbited  in  the  outfeed starwheel and,  while rolling,  the bottles receive their coating of liquid from the applicator surface. The applicator surface is spongy and maintains a coat-ing of the liquid on it which is applied to the sur-face by means of spray nozzles which are timed to spray the applicator surface by projecting a fan-shaped spray through the space between successive bot-tles as the bottles are moving orbitally by the rotat-ing outfeed starwheel.

IPC: B41F7/02
Filed: 1992-01-14
Granted: 1995-08-29
Abstract: To positively lock in position  a pair of eccentrically journalled blanket cylinders (3, 6), movable between three positions, namely in engagement with a first pair of plate cylinders (1, 4), or a second pair of plate cylinders (2, 5), or in engagement with neither plate cylinder, the blanket cylinders having a printing substrate  passed therebetween for perfecting printing, the eccentric bearings (7, 8) for the blanket cylinders are secured to operating disks(9, 10) which, each, are coupled to a scissor-link arrangement formed by two pairs of links (16, 18;17, 19), joined at a common pivot point.  Pneumatic cylinder-piston arrangements move the pivot points (1618, 1719)      to compress one of the scissor link pairs to V position,while the other  link pair is moved  to slightly over-center in-line position for a toggle or locking effect;  when both scissor link arms are in half-open V position, the blanket cylinders are disengaged from the plate cylinders. Abutment stop means, located between the blanket cylinders, receive the pivot points, when the link arms are in essentially in-line or toggle position, and adjustment bolts (42, 43, 44, 45) can control the position of the scissor link arms, when in V position for accurate adjustment of the locked position of the blanket cylinders.

Title: Direct reduction process in rotary hearth furnace
Inventor: KOTRABA NORMAN LOUIS
IPC: C22B7/04
Filed: 1992-03-03
Granted: 2001-11-20
Abstract: The invented pellet reclamation process includes forming green pellets of a mixture of steel furnace dust, a carbonaceous material such as coal, charcoal, lignite, petroleum coke, or coke, and an organic binder. The green pellets are fed over a layer of burnt pellets on a rotary hearth furnace which successively conveys the pellets first through a drying and coking zone in which the pellets are dried and any volatile matter driven out of the carbonaceous material. The pellets then travel through a reduction zone where the pellets are subjected to a higher temperature at which the contained iron oxide is reduced and remains within the pellets and the zinc, lead and cadmium oxides are reduced, volatilized, re-oxidized and carried off as oxides in the waste gases. The reduced pellets (DRI) are ultimately carried into a discharge zone where they are discharged from the rotary hearth furnace. An apparatus for performing the process is also disclosed.

Title: Image recovery mixer
Inventor: TAHIM RAGHBIR S
IPC: H03D9/06
Filed: 1992-04-02
Granted: 1997-03-25
Abstract: A microwave mixer is formed of three orthogonally oriented  waveguides,  each  having  a  rectangular cross-section defined by a pair of opposed broad walls and a pair of opposed sidewalls wherein the ratio of cross-sectional dimensions typically is 2 : 1.  The mixer includes  an input coupling probe, a mixing  region,  and an output  filter  disposed serially along a first of the waveguides.  A second of the waveguides applies a reference LO signal via the probe to the mixing region, the mixing region including at least one diode with two diodes being employed  in  the  preferred  embodiment  of  the invention.  A section of dielectric board serves to support the diodes of the mixing region, components of  the  filter,  and  the  probe  in  the  first waveguide.    The third  waveguide  applies  an  RF input signal to the mixing region via an input port in  a  side  of the  first  waveguide,  and via  an impedance matching taper and a waveguide section of reduced height which impedes egress of both an IF and an image signal produced in the mixing region by interaction of the LO and the RF signals.  The filter is located at the mixer IF output port for reflecting an image-frequency signal back to the diodes of the mixing region for further interaction with the LO signal to generate additional IF signal in phase with the originally produced IF signal for additional  power  and  a  significantly  higher signal-to-noise ratio.

Granted: 2000-09-12
Abstract: A method of detecting conditions during the operation of a transport refrigeration unit (20) which may cause shutdown, and then modifying the operation of the unit in an attempt to find an operating condition that will keep the unit operating safely. the unit includes a compressor (26) driven by an engine (30) operable at low and high speeds. Upon detecting (264) an over-temperature condition of the engine a first modification (282) is initiated, including switching the engine to low speed.      If the engine temperature dogs not drop to a safe value (288; 292), a second modification (296) is initiated. If the engine gas in low speed (280) when the over-temperature condition was detected, the second modification is initiated immediately. Upon detecting (316) a low oil pressure condition, the engine is switched (316) to high speed. If the oil pressure rises to a safe level, engine operation is continued at high speed. Appropriate alarms (326) accompany the modified operating conditions.
