Title: Assembly for the unwinder end of an off-machine paper web handling line
Inventor: RAUTIAINEN PENTTI
IPC: B65H19/18
Filed: 1994-02-17
Abstract: When a new roll is changed in an off-machine coating line into the unwinder (1), problems are encountered in matching the tension of the web (16) received from the expiring roll (13) to that to be paid off from the new roll (12). Differences in web tension cause web breaks during roll change. According to the invention, the web is supported at the unwinder (1), and subsequently, at the following dryer cylinder group (2) by means of a support felt (3) serving to the end of equalizing differences in web tension. The web received from the first roll (13) is spliced to the tail of a second, full roll (12) by pressing the web (16) received from the first roll against the web of the second roll via a support felt (3) by means of a splicing roll. Next, the web is fed supported by the felt (3) to a dryer cylinder group (2) comprising VAC and steam cylinders (20, 21) where the damp web is dried for subsequent coating.

Patent CA-2118259-A1 (CA)
Inventor: JEFFERY ANDREW B
IPC: B01D39/08
Filed: 1994-10-17
Abstract: A self-supporting filter element is produced from a precursor fiber web according to one of several methods. The precursor fiber web contains heat-shrinkable fibers or binder fibers or both. The web is exposed to temperatures sufficiently elevated to cause shrinkage of the fibers or melting of the binder. After cooling the web, the filter elements produced are self-supporting, and may have densities up to 500 kg/m3 to improve filtration while retaining good functional characteristics for operating pressure drop and air permeability. The self-supporting filter elements can be constructed of one material, and thus may be suitable for recycling.

Inventor: LIEBL RONALD J
IPC: F24F11/02
Filed: 1994-05-17
Abstract: Disclosed herein is a temperature control system for multi-zone temperature control with setback control.  The system includes a thermostat (10) associated with each zone of a building, and a central control unit (12) which communicates with each thermostat (10) to send temperature setpoint values to each thermostat (10) for the purpose of conserving energy and reducing energy consumption during certain times of the day.  Each thermostat (10) is associated with either a heating or cooling device (14), where setup temperature values are sent from the central control unit (12) to the thermostats (10) where cooling devices are used in place of heating devices.  The thermostats (10) are designed to operate as stand-alone units which control the temperature within a zone based upon a temperature setpoint stored at the unit.  The temperature setpoint values are replaced by the higher or lower temperature setpoint values transmitted to the thermostats by the control units during setback or setup time periods.  To avoid the requirement of installing communication wires between the central control unit (12) and thermostat (10), each thermostat (10) and the central control unit (12) includes communications circuitry (30, 46) which allows the thermostats (10) and control unit (12) to communicate over the power conductors (36, 38) within the building.

Abstract: Abstract of the Disclosure:     A railroad freight car includes a loading platform and two wheelsets, two double-axle running gears or two bogies, and cushioning is effected by leaf suspension springs suspended by links from spring brackets.  The object of the invention is to provide a railroad freight car by using simple, econom-ic devices, in which a facility is provided for driving the railroad freight car beneath cargoes, especially swap bodies or interchangeable containers,  for raising the loading platform and,  following the reception of the cargo,  for lowering the loading platform back into a travel position so as to enable the railroad freight car to be loaded and unloaded independently from loading appliances extraneous to the car.  This object is achieved by providing a lifting element interposed between each suspension ring and an associated spring bracket of the loading platform or of the bogie frame.  The lifting element can raise the loading platform relative to the wheelsets or to the double-axle running gear or with the bogie frame,  relative to its wheelsets.

Title: Ceria-alumina oxidation catalyst and method of use
Inventor: FARRAUTO ROBERT J
IPC: B01J23/10
Filed: 1992-11-20
Abstract: Oxidation catalyst compositions include a catalytic material containing ceria and alumina each having a surface area of at least about 10 m2/g, for example, ceria and activated alumina in a weight ratio of from about 1.5:1 to 1:1.5. Optionally, platinum may be included in the catalytic material in amounts which are sufficient to promote gas phase oxidation of CO and HC but which are limited to preclude excessive oxidation of SO2 to SO3.  Alternatively, palladium in any desired amount may be included in the catalytic material. The catalyst compositions have utility as oxidation catalysts for pollution abatement of exhausts containing unburned fuel or oil. For example, the catalyst compositions may be used in a method to treat diesel engine exhaust by contacting the hot exhaust with the catalyst composition to promote the oxidation of the volatile organic fraction component of particulates in the exhaust.
