Inventor: NEFF JAMES A
IPC: F16K31/06
Filed: 1992-01-24
Abstract: A direct solenoid operated poppet valve having an adjustable valve seat that provides a selectively variable flow orifice for supplying a preset air flow requirement.

Patent CA-2063235-A1 (CA)
Inventor: STAUBER HANS-ULRICH
IPC: B65H75/00
Filed: 1992-03-17
Abstract: The method described, printed products, which are received from a processing stage (10) in an overlapping arrangement, to be temporarily stored and rearranged in such a way that they can in turn be fed into a processing stage (20) for further processing in an overlapping arrangement which may have a different number of imbricated streams, different speeds and a different sequence of various printed products. The method is carried out in three method zones: in the first method zone (1) which is connected to the processing stages (10) and (20) and in which imbricated streams (S) are wound onto winding cores (WK) or rolls (W) are unwound to make imbricated streams (S); in the second method zone (2), in which rolls (W) and cores (WK) are transported between the buffer zone and the winding station and in which storage units (horizontal pairs of rolls (WP) and core collars (R)) are made and unmade; and in the third method zone (3) in which storage units (WP, R) are placed in and taken out of store. Printed products, and storage aids which solely consist of winding cores with tapes, are manipulated in all method zones. One advantageous feature of the method according to the invention is that the devices used in the individual method zones are specific to those method zones and not to products or storage aids.

Filed: 1991-06-07
Abstract: A method and apparatus are provided for monitoring the performance of fuel cells arranged in series. More particularly, the method and apparatus involve the measurement and comparison of fuel cell performance indicators, such as voltage, in groups of cells connected in series. In a first embodiment, the voltage across each fuel cell group is compared to a reference vol-tage equal to a predetermined minimum voltage. In a second embodiment, the voltage across each group is compared to a refer-ence voltage equal to the average across all fuel cell groups. In a third embodiment, a reference voltage equal to the voltage across one group is compared to the voltage across each of the other fuel cell groups. In a fourth embodiment, the voltage across each group is compared as a reference voltage to the voltage across an adjacent fuel cell group. Other embodiments comprising various combinations of the first, second, third and fourth embodiments are also provided. An alarm is activated, and supply of fuel to the cells discontinued, when the measured voltage for a fuel cell group varies from the reference voltage by more than a predeter-mined voltage differential.

Filed: 1991-10-03
Abstract: Method for obtaining acetic acid derivatives, such as glycin, IDA and NTA by dehydrogenation of mono-, di- and triethanolamine, respectively, in the presence of a Copper-Raney catalyst. Such method includes a step consisting in regenerating the catalyst spent in order to reuse it in successive reaction cycles. The regeneration method is comprised of the treatment of the spent catalyst with backflowing formic acid, filtering and repulping it with demineralized water and NaOH till the washing waters reach a sligthly alkaline value. The regenerated catalyst may be reused in successvie reaction cycles maintaining an average efficency of 87 %, that is to say of the same order of magnitude as when using a new catalyst.
Patent CA-2071275-A1 (CA)
Inventor: HALLEY DAVID
IPC: A23B9/20
Filed: 1992-06-15
Abstract: A storage vessel for storing grain or other natural products comprises a gas-impermeable enclosure having a water-vapour-permeable membrane to allow the grain to breath and dry, and to prevent condensation and mould growth. The membrane is impermeable to oxygen gas to allow a reduced oxygen atmosphere (e.g. 3 to 7%) to be established as oxygen is used up by insect pests within the grain.  The insects are unable to survive at such low levels of oxygen.  Thus the grain is protected against pests without the use of chemical pesticides.

Title: Method and apparatus for reducing wafer contamination
Inventor: HURWITT STEVEN D
IPC: B01J3/02
Filed: 1991-08-22
Abstract: A pressure sealed chamber (15) such as load lock or processing chamber of an apparatus for processing substrates is operated with a guide plate (30) spaced from a substrate (20) supported in the chamber to form a gap (31) that covers the substrate surface (28) to be protected from contamination by moisture (27a) condensing in the chamber during the rapid evacuation thereof or particulates (27) picked up by the gaz during turbulent flow into or out of the chamber. During the evacuation of the chamber, by either pumping or venting, clean dry gas is introduced through an orifice (35) in the center of the plate so as to flow outwardly from the edge of the gap at a pressure sufficient to displace or otherwise prevent gas borne moisture condensate and particulates in the chamber from entering the gap and contaminating the surface to be protected of the substrate. During evacuation of the chamber, gas is introduced through the gap at a flow rate less that of the evacuating gas. During filling of the chamber, at least some of the filling clean gas is introduced through the orifice in the plate at a sufficient rate to prevent gas borne particulates from entering the gap.
