Title: Method for optoelectronic control of metal oxygen cutting and device thereof
Inventor: KADOCHKIN EVGENY L
IPC: B23K7/00
Filed: 1990-02-06
Abstract: METHOD FOR OPTOELECTRONIC CONTROL OF METAL    OXYGEN CUTTING AND DEVICE THEREOF                      ABSTRACT      The method for optoelectronic control of the metal oxygen  cutting process comprises the successive opera-tions of detecting the torch flame luminance prior to cutting and evaluating this luminance, detecting the metal surface luminance during its heating at the initial cutting site and evaluating this luminance, detecting the luminance of   the metal cut frontal surface and evaluating this luminance, and generating discrete control signals. In accordance with these control signals commands are issued to cut off fuel gas and heating oxygen supply, to enable or disable cutting oxygen supply to the cutting torch and torch displacement.     The device embodying this method for optoelectro-nic control of the metal oxygen cutting process com-prises at least one  cutting torch with channels to feed the fuel gas and heating oxygen and a channel for feeding cutting oxygen. Each cutting torch is linked to torch displacement dirves. The channel for feeding cutting oxygen houses a first optical sensor generating electric signals indicative of torch flame luminosity prior to cutting, a second optical sensor generating electric signals indicative of the metal surface lu-minosity during its heating at the initial cutting site, and a third optical sensor generating electric signals indicative of the luminosity of the metal cut frontal surface. The first, second and third optical sensors are electrically connected via a first, second and third network of connected in series amplifier and generator and via a control system to fuel gas and heating oxygen supply and cutting oxygen supply sys-tems and to torch displacement dirves.

Abstract: A wave soldering apparatus and process occurs in an atmosphere which substantially excludes oxygen.  By providing a pressurized effect on an element to be soldered while passing through a solder wave, fluxless soldering is accomplished avoiding the necessity to remove flux residues.          The element is preheated in a shield gas atmosphere substantially excluding oxygen, moved in a predetermined path so that at least a portion of the element passes through the solder wave which is oscillated while the element is in the solder wave and maintained in the shield gas until solder on the element has solidified.

Abstract: ABSTRACT           There are disclosed foot rest devices having a flat rectangular side forming a chord with an opposed curved side which, in turn, has two partial cylindrical sections. In one embodiment, the two partial cylindrical sections have an equal radius with respect to one another.  In another embodiment, one of the two partial cylindrical sections has a greater radius than the other.  This gives the foot rest device different modes of use, namely, a flat side down where the user can rest a foot on one or the other cylindrical portion, or both; or curved side down, where, in the first embodiment, the user can rest his foot on one of the two slopes, or, in another embodiment, the user can rest his foot on a steeper slope or alternately, on a flatter slope, depending on which cylindrical portion rests on a substrate.

Title: Manually operated appliance, in particular for a double dispensing cartridge for two-component substances
Inventor: KELLER WILHELM A
IPC: B05C17/005
Filed: 1990-07-12
Abstract: Abstract of the disclosure A  manually  operated  appliance,  particularly adapted for a two-component substance double dispens-ing cartridge,  features two rams between which a thrust member is disposed in cylindrical sliding guides.  Pivotably attached to the thrust member are ratchets, the pawls of which engage with an indent-ation extending on either side of each ram in order to move the rams including thrust pieces in the direction of the cartridges.      A thus guided thrust member, which is essentially movable only in parallel to the rams,  provides for perfect  force  transmission  and  exact  proportioning even when relatively great pressures occur and differ-ent diameters of the individual component cartridges are used.

Abstract: ABSTRACT OF THE DISCLOSURE          An ultrasonic humidifier has a base having a removable water reservoir connected to it. The water reservoir feeds water to an atomizing reservoir having an ultrasonic transducer connected to it.  A fan generates an air stream which sweeps past the atomizing reservoir and mixes with the atomized water produced by the ultrasonic transducer to form a humidified air stream carried into a humidified air vent.  A humidified air nozzle connected to the humidified air vent delivers the humidified air to the environment.  A drip chute positioned partially within the humidified air vent delivers condensate noiselessly back to the atomizing reservoir into which it extends.

Title: Multi-nodal communication network with coordinated responsibility for global functions by the nodes
Inventor: AGGERS JOHN R
IPC: H04L12/417
Filed: 1991-01-17
Abstract: ABSTRACT OF THE DISCLOSURE             An electronic network of communication and processing nodes particularly suitable for control of environmental systems has pluralities of the nodes which are sources for certain types of status messages each of which comprise communication of a particular kind of information on the network.  To resolve the question of which of the nodes shall furnish each type of status message, one node is designated the coordinator node, and it stores a status message source list which associates the node assigned for each type or status message with the status message type itself and transmits all or a part of the list on the network to allow each of the status message source nodes to determine therefrom their responsibility with respect to each status message type.  These status message source nodes can also transmit request messages on the network by which they request responsibility for furnishing a particular type of status message.  Upon acceptance of the request in a request message, the coordinator node enters the node transmitting the request request into the status message source list in association with the status message type.  In one embodiment, the coordinator node monitors the transmission of status messages on the network and if an instance arises where a status message is supplied by other than the one specified in the status message source list, takes remedial action.  In another embodiment each node is given a priority for a particular type of status message, allowing the coordinator node to replace a node assigned to a particular type of status message with a node having higher priority for that type of status message and which requests in a request message, responsibility for supplying that status message type.

Abstract: A cylindrical filter is formed from a sheet of filter material which includes two connected layers of filter media. Opposed edges of the sheet are joined to form the cylinder by separating the media adjacent the edges and then sealing together the first of the separated layers followed by sealing the second of the separated layers. The two seals are spaced inwardly of the edges and are spaced from one another. In this way, failure of one seal does not result in failure of the cylindrical filter.
