Patent CA-2268402-A1 (CA)
Inventor: ARRAITZ ANNE MARIE
IPC: F01D25/24
Filed: 1999-04-07
Abstract: The method allows one to improve the seal on the inside of the rectifiers (3) of the high pressure turbine at the lower platform (6). It mainly consists of applying to the lower part of the external surface of the liner (8), a protective deposit before carrying out a filling by diffusion brazing between this liner (8) and the rectifier (3). Such a deposit, particularly of anti-adherent ceramic, makes it possible for the braze to avoid fixing the lining (8) onto the rectifier (3) at the lower platform level (6). Application to turbojet engines

Abstract: Small particles suspended in the air are becoming increasingly widely known as causes of ill health and death. Several government reports place the death toll in the thousands every year.   These small particles come from a large range of sources, and occur both inside and outside buildings. In large, modern office buildings, exterior pollutants are largely removed by efficient air filtration mechanisms. Thus, the particles in this venue come from interior sources. Experience has shown that one of the major interior sources is office machines - specifically copiers and printers using the xerographic process.1 These machines use fine particles as an integral part of their process. Once this powder escapes the machine, it is so fine that it stays suspended in the air for hours. From that suspended state, it affects the health of office workers in the general area.      While it is a fact that the majority of xerographic machines do not release significant amounts of particles, testing over several years has demonstrated that the release of particles does happen with almost all types of xerographic equipment. It is not limited to one make or model. There is no current way to predict which xerographic machine will release particles and which will not.   Current xerographic machines do contain filters. However, these filters are for ozone control, and are ineffective against particulates.   The objective of this invention is to provide a device to capture escaping particles before they can affect nearby staff.     While office and home air cleaners are common, we are not aware of any other inventions that aim to filter out escaping dust before it can escape the xerographic machine.   This invention aims to filter one particles originating from xerographic machines before they can enter the general room air.     1 The term "xerographic" is used here to refer to the general process whereby a powdered toner is fixed to a piece of paper through the applications of electrical charges and heat. It is not meant to refer to the specific brand name of photocopiers.  Examples of machines that may use xerographic processes are photocopiers, laser printers and fax machines.

Patent CA-2278260-A1 (CA)
Inventor: STEELE RICHARD L
IPC: B65B31/02
Filed: 1999-07-20
Abstract: A platen machine for filling and sealing packages is provided having an upper platen and a lower platen journalled and independently moveable on a common alignment shaft to provide a close tolerance sealing mechanism with an independently operated heat seal element. The novel platen machine relocates clamping forces from the support frame to the alignment shaft so that the common alignment shafts bears the clamping forces and the carrier merely relies upon the frame to support the weight of the machine and not clamping forces. The upper platen moves toward the lower platen and the lower platen moves toward the upper platen to clamp a package between the two platens before an independently operated heat seal element is activated to advance to the clamped package and provide a heating and sealing cycle independent of the clamping cycle. Optional filling, gassing and evacuation can be provided during the clamping of the package without involving the separate heating and sealing operation.

IPC: H04L29/06
Filed: 1999-07-29
Abstract: The present invention concerns a method, a terminal device, a node, a program module, and a user interface for determining features required for a communication relation. An input device (IN) determines initial features as input values (INPUT) which are necessary for classification of the communication relation and transmits them to a sort device (SORT) which sorts the initial features into feature groups, with the first feature group (INKP) comprising the [features] of the initial features which concern at least two communications partners to participate in the communication relation; a second feature group (INDT) is comprised of those [features] of the initial features which concern at least one data type to be transmitted in the framework of the communication relation; and a third feature group (INCT) which comprises the [features] of the first features which concerning at least one connection type for the communication relation. The features sorted in this manner are transmitted to a processing device (MAT) which input them into a decision matrix and determine as output variables (OUTPUT) from this matrix the features required for the communication relation as second features.

Title: Method to control a switching unit and an arrangement working according to the method
Inventor: KARLSSON CARL MICHAEL
IPC: H04L1/24
Filed: 1998-01-27
Abstract: The present invention relates to a method to control an established wideband connection through a switching unit regarding frame integrity of the time slots. The invention also relates to an arrangement adapted to work according to the method. The invention is suitable to be used in a switching unit of TST-structure. A first counter (41), related to respective input selector stage (1), counts incoming data frames. This first counter (41) cycles through a predetermined number of states, where one state is a control-state. Each time slot belonging to the wideband connection to be tested is given a control mark during one of the control-states. A second counter (42), related to respective output selector stage (2), counts outgoing data frames. The second counter (42) cycles through the same number of states as the first counter (41).  Marked time slots are detectable by respective output selector stage (2). The state of the second counter and the output channel number of the control marked time slot is stored as a marked time slot is detected. The wideband connection to be tested is regarded correctly established through the switching unit if the time slots belonging to the wideband connection are all detected during a mutually same state of the second counter (42).

Abstract: A soil opener system is described which is capable of providing multiple ranges of downpressure so as to accommodate the varying field conditions likely to be encountered. The downpressure assembly includes plural springs having different spring constants in series to bias a planting tool toward the ground. Dual or multiple ranges of downpressure are selectable by setting the amount of precompression of the spring assembly.
