Granted: 1981-10-06
Abstract: La présente invention a pour objet une armature pliable de rigidité accrue pour bâtiment préfabriqué comprenant au moins deux poteaux verticaux métalliques de section en H sur lesquels sont fixées par l'intermédiaire de charnières et prennent respectivement appui au moins deux poutres métalliques convergentes ayant la même section en H que les poteaux verticaux, au moins deux renforts disposés diagonalement et symétriquement entre chaque couple de poteaux verticaux et poutres et au moins un autre renfort horizontal disposé transversalement entre les deux poutres convergentes.  La section en H des poutres et des poteaux adjacents délimitent deux parties creuses, lesquelles déterminent respectivement l'avant et l'arrière de l'armature.  Les extrémités des poteaux et des poutres sont taillées en angle de façon à ce que les poteaux et poutres prennent appui les uns sur les autres sur toute leur section en H.  Les charnières donnent vers l'extérieur ou l'intérieur de l'armature suivant qu'elles sont placées respectivement à la jointure des poteaux et des poutres ou sous la jointure des poutres opposées convergentes du toit.  Les renforts disposés diagonalement sont fixés par leurs extrémités sur la face interne des poteaux et sur la face interne des poutres entre lesquels ils s'étendent, les extrémités des renforts étant soudées à des plaques d'attache métalliques.  L'autre renfort horizontal disposé transversalement est fixé par ses extrémités sur la face interne des poutres convergentes entre lesquelles il s'étend, les extrémités du renfort étant soudées à des plaques d'attache métalliques.

Abstract: Case 151 VALVE CLOSURE FOR RAILWAY CAR CUSHIONING DEVICE              James R. Reinhardt Houston, Texas Mark P. Scott Houston, Texas Abstract of the Disclosure An end-of-car railway car cushioning unit has a cylinder and a cylin-drical piston mounted in the cylinder with the piston rod secured to the piston extending through an opening in the rear end of the cylinder with the piston forming a high pressure fluid chamber on the front face thereof and a low pressure fluid chamber on the rear face thereof. The piston has a plurality of openings therethrough and a metering valve is mounted in each of the openings to meter fluid flow between the low pressure chamber and the high pressure chamber. Each metering valve has a buff flow passage and a restricted draft flow passage. At least one selected metering valve has a cylindrical extension thereon projecting from the front face of the piston and adapted to engage an end wall of the high pressure chamber as the piston approaches the end of its buff stroke to block the flow of fluid from the high pressure chamber to the associated metering valve adjacent the end of the buff stroke. The extension is mounted for a limited inward movement upon contact with the end wall forming the cylinder to permit movement of the piston after such contact. The metering valves having the closure extension thereon are set to open at a lower force level than the remaining metering valves and a high force level is thus required for additional buff travel after the closure extension contacts the cylinder end wall.

Title: Process for pressure stripping of  sulfur dioxide from buffered solutions
Inventor: VASAN SRINI
IPC: C01B17/60
Filed: 1978-10-06
Granted: 1982-01-12
Abstract: Abstract It is known to strip sulphur from aqueous citrate solutions using low pressure steam. This process is disadvantageous in that is requires large volumes of steam. The present invention seeks to overcome this draw-back by providing in a process for the desulfurization of gases wherein sulfur dioxide is removed from the gases by absorption in citrate buffered aqueous solution which undergoes a regenerative process to yield sulfur-based by-products, the improvement resulting in the recovery of sulfur dioxide from the citrate buffered aqueous solution comprising heating the aqueous solution containing absorbed sulfur dioxide to a temperature above 212°F. and to strip the sulfur dioxide therefrom, maintaining the pressure substantially greater than atmospheric pressure, and recovering sulfur dioxide vapor.

Abstract: ABSTRACT OF THE DISCLOSURE        A video magnetic tape control time code reading method and apparatus enables a control time code comprising binary coded times and frame numbers to be read, independently of the direction and speed of transport of the video tape, to ascertain whether the control time code corresponds to a recorded video signal having a frame frequency of 30 or 25 frames per second. Use is made of the fact that in a 30 frame per second control time code the frame numbers always alternate regularly between odd and even, whereas in a 25 frame per second control time code the frame numbers have irregularities in the otherwise regular alternation between odd and even, such irregularities occuring at every transition from one second to the next.

Abstract: ABSTRACT     The invention is a novel method and apparatus for subterranean drilling and mining, particularly suited to alluvial deposits.  The method uses water jets from the lower end of the apparatus to loosen and remove soil.  Part of the water is bled off to raise a piston and associated weight, the water being evacuated from the cylinder in which the piston operates from time to time to give periodic impulses to the outer casing.  Air may be admitted to the system during the mining mode to increase its efficiency.

Consequently a comparatively low lubricant feed pressure is adequate.  Return of lubricant into the feed is advantageously excluded by a non-return valve arrangement (8d,15).     Preferably a non-return valve member (15) is arranged in the region of the mouth (9) from the lubricant feed, whereby low-inertia operation results with secure maintenance of pressure in the lubricant space (3b).

Abstract: INDUSTRIAL COMMUNICATIONS NETWORK                   ABSTRACT OF THE DISCLOSURE      An industrial communications network includes micro-processor-based interface circuits which each connect a controller such as a programmable controller to a high speed serial data link.  Each interface circuit connects to the data link and its associated controller, and each is operable to receive messages on the data link directed to its associated controller.  In addition, each interface circuit can assume mastership of the communications network when the existing master generates a poll command indicating it is ready to relinquish mastership.  As a result, the communications network will continue to function even though one or more controllers or their associated interface circuits become inoperable.

Abstract: Abstract of the Disclosure A coating of wear resistant tungsten carbide is applied to a photo-etched roto-gravure cylinder, the coating having a thickness in the range of from 15 to 35 microns.  Tungsten carbide powder is supplied to a plasma flame spray gun by means of a powder feeder which supplies powder particles at a uniform density and at given sizes.       The feeder comprises a hopper having air inlet and outlet passages and vertically spaced porous membranes which confine the powder and permit the passage of air.  Air flow through the hopper suspends the powder particles of a desired diameter range adjacent a spray gun feed conduit.  When copper cylinders are to be coated, the surface is allowed to oxidize to promote a chemical bonding of the coating to the surface.

Abstract: Abstract of the Disclosure Solar collectors whose absorbers are made of a conventional building material form the outer surface of the roof and wall of a building.  Air flows behind the absorbers and heat is transferred to the air by expanded metal conductors which extend from adjacent the outside surfaces of the absorbers into the flow passages.  Heat from the collectors is stored in a system including a cold tank of liquid, a heat tank of liquid at a higher temperature, and a hot water tank of liquid at an even higher temperature.  A heat pump may transfer heat from the cold tank to the heat tank and from the heat tank to the hot water tank.  Cold and heat exchangers are provided in each tank for receiving heated air from the collectors and transferring heat therefrom to the liquid in the tank, and the exchangers in the cold and heat tanks transfer heat between the liquid in the tanks and air from or to the building.  Air flows to and from the collectors, tanks, and buildings in ducts formed by the floor and roof beams and wall slabs.
