Title: Process and apparatus for initiating and/or promoting chemical processes
IPC: B01J19/12
Filed: 1990-10-11
Abstract: The invention relates to a method of initiating and/or promoting chemical processes by irradiation of starting materials present in a gas atmosphere with electromagnetic waves to form reaction products. In order to combine the advantages of the hitherto known irradiation with long-wave electromagnetic waves such as, for example, microwaves, and with short-wave electromagnetic waves such as, for example, UV light, without the disadvantages thereof in one method, it is proposed according to the invention to generate, by means of irradiation of a gas under a vacuum with long-wave electromagnetic waves (10), a shorter-wave radiation (12) with which the starting materials (5) are irradiated, or to put the starting materials themselves under a vacuum and to irradiate them directly with the long-wave electromagnetic waves. The invention also relates to an apparatus for carrying out the method according to the invention. <IMAGE>

Title: Interrupt handling for a computing system
IPC: G06F9/48
Filed: 1990-05-31
Abstract: A computing system including a host processor and at 
least one intelligent subsystem having attached devices, has two 
interrupt ports. The one intelligent subsystem and the attached 
devices are each viewed as a logical device by the host processor, and 
each is assigned a device identification number. The host processor 
provides direct and indirect commands to the logical devices. For 
direct commands, first physical interrupts are provided to the host 
processor serially from the logical devices through an Interrupt 
Status Port. For indirect commands, logical interrupts are stored in 
predetermined bit positions in a Device Interrupt Identifier Port 
(DIIP) in accordance with the device identification numbers. A second 
single physical interrupt is provided to the host processor as long as 
there is at least one logical interrupt pending from at least one 
logical device as the result of an indirect command. The host 
processor reads the DIIP to determine which logical devices have at 
least one logical interrupt pending for an indirect command. A 
plurality of logical interrupts for a single logical device may be 
cleared with a single reset interrupt command from the host processor.

Title: Assembly for the unwinder end of an off-machine paper web handling line.
Inventor: RAUTIAINEN PENTTI
IPC: D21F7/00
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. <IMAGE>
