Patent BR-8101851-A (BR)
Inventor: WEISS H
IPC: B23K1/16
Filed: 1981-03-27
Abstract: Tubing is made by continuously pulling steel strip at a predetermined feed speed from a supply, shaping the strip into a multilayer tube of a predetermined mass per unit length, and advancing the tube at the feed speed through a soldering station. The strip is coated with a solder-type material and an electric current is passed through the tube between a contact engaging the tube in the station and a contact engaging the tube downstream of the station to fuse the solder and tube together. The contact outside the soldering station is displaced so that the spacing between the contact is varied substantially proportionately with the product of the feed speed and the predetermined mass per unit of length of the tube. Downstream of the soldering station the tube and solder are cooled to bond the tube together.

Abstract: An improvement in known processes for preparing substituted carboxylic acids useful as acylating agents which comprise reacting (A) at least one aliphatic polymer of one or more lower olefins with (B) an acid reactant selected from the group consisting of fumaric acid, itaconic acid, maleic acid, and the corresponding anhydrides, lower alkyl esters, acyl chlorides and acyl bromides, in the presence of chlorine can be improved by the steps of (i) reacting at a temperature of about 100<o>-200<o>C, a mixture of (A) and (B) in the presence of about 0.05 to 0.15 equivalent of chlorine per equivalent of (A) until of the chlorine has reacted to provide a first intermediate product, (ii) continuing the reaction in the absence of chlorine at a temperature of from about 180<o>-250<o>C until a conversion of 0.4 to 1.1 equivalents of (B) per equivalent of (A) is attained to provide a second intermediate product, and (iii) reacting said second intermediate with about 0.2 to 1.5 equivalents of chlorine per equivalent of (A) used in step (i) at a temperature of about 180<o>-225<o>C. The carboxylic acids produced by this improved process can be used, per se, in lubricants and fuels and as acylating agents in reactions with amines, alcohols, reactive metals or reactive metal compounds to form derivative products which are useful, for example, as additives for lubricants and normally liquid fuels.

Abstract: In the representative embodiments of an ink jet array described in the specification, a linear array of ink jet orifices (31-34) is supplied with ink from pressure chambers (35-38) alternately disposed on opposite sides of the array to permit close spacing of the ink jet orifices. At the end opposite from the ink jet orifice, each pressure chamber (35-38) communicates with a low acoustic impedance chamber (43-46) to reflect negative pressure pulses from the pressure chamber back through the chamber as positive pulses and to prevent pressure pulses from being transmitted to the ink supply. In addition, a high-impedance passage (47-50) between the low acoustic impedance chamber associated with one pressure chamber and the pressure chamber for the adjacent ink jet provides a continuous flow-through passage from the ink supply port for one ink jet to the ink supply port for an adjacent ink jet. This permits continuous circulation by thermal convection of the ink when the ink jets are not in use to prevent settling of pigment in a pigmented ink and to transport ink containing dissolved air from the region of the ink jet orifice to a deaeration passage.

Abstract: A continuous motion cylindrical can decorator is provided with mandrels that receive undecorated cans and a deco chain that carries decorated cans through a curing oven. The mandrels are mounted along the periphery of a continuously rotating carrier. Chain speed is much slower than linear mandrel speed and spacing between pins on the chain is much less than spacing between mandrels. Interposed between the chain and the mandrel carrier is a continuously rotating transfer carrier having a plurality of suction holding devices thereto. As the holding devices move through a transfer region they are in single file and receive cans that are blown from the mandrels. In the transfer region mandrel linear speed is substantially greater than linear speed of the holding devices, and spacing between the latter is much less than spacing between mandrels As the loaded suction holding devices move downstream through a pickup region cans thereon are loaded on two rows of pins carried by the deco chain. Linear speed of the holding devices while moving through the transfer region exceeds chain speed, and in this region the holding devices are spaced apart by a distance that exceeds pin spacing. By the time the holding devices reach the pickup region they are arranged in two rows, are spaced apart and are moving at a speed such that they essentially track the moving pins while the latter are being loaded.

Abstract: The invention proposes a testing method and associated arrangement for electronic circuitry that combines functional components that are interconnected by handshake channels. Various of such channels are now provided with an inbreaking junction and an outbreaking switch as a test component pair. The junction has two passive ports and one active port. The switch has one passive port and two active ports that are selected through a passive control port. In this way inbreaking into an outbreaking from the channel is rendered feasible. Now inbreaking is done on a first channel, and outbreaking on a second channel, so that thereby all components are tested that lie between the first channel's junction and the second channel's switch.
