Patent ES-420662-A1 (ES)
Title: Pressure regulator valve
IPC: F16K17/10
Filed: 1973-11-19
Abstract: The interior of the bellows is sealed at atmospheric pressure so the pressure on the outside of the bellows is resisted by the atmospheric pressure within the bellows as well as by the spring. When the pressure on the outside of the bellows (which is evaporator pressure in a refrigeration system) exceeds a predetermined amount, the bellows tends to collapse and the head of the bellows pulls away from the actuating pin and allows the spring acting on the pilot valve to open the pilot valve whereupon the pressure to the right of the head of the piston is reduced, allowing the piston to move to the right against the return spring force and thus open the outlet by moving the end of the piston wall past the slot in the stationary sleeve. When the pressure falls below the desired amount, the bellows expands and moves the head of the bellows against the actuating pin to close the pilot valve. Flow through the bleed hole in the end of the piston to the pilot valve chamber rapidly raises the pressure therein so that the return spring can move the piston to close the outlet. Even with the outlet closed, the small port in the piston sleeve allows enough refrigerant flow to insure adequate flow to the compressor to keep the compressor lubricated. The bleed hole in the piston head is sized to require substantial opening of the pilot valve which, therefore, minimizes false opening of the main valve. Controlled leakage to the groove at the pilot end of the piston blocks flow from the pilot valve chamber to the main outlet and stabilizes valve operation.

Abstract: A brake control device for railway vehicles has a remote indicator for indicating the state of connection of a plurality of control lines for controlling a plurality of valves connected to a source of control energy in order to introduce a predetermined level of brake pressure into a brake cylinder in response to particular connections of the control lines. A plurality of control paths corresponding to the plurality of control lines are provided and the paths are equal in length or subtend equal angles. The sequence of these paths is designated by position m beginning at 0, 1, 2 . . . . Each path comprises an alternating series of 2m/2 sensing and non-sensing zones which are sensed by a plurality of sensing elements. One of the sensing elements is located opposite the path of the highest position and two additional sensing elements which are spaced longitudinally along a path are located opposite each of any additional paths. One of the pair of sensing elements is positioned before and the other after the sensing element of the highest position path or with respect to the corresponding elements of the next highest path. Monitor means are connected to the sensing elements for selecting in each state of connection of the control lines only one of the two sensing elements of the second highest position path over a sensing or non-sensing zone and for selecting one of the two sensing elements of the next lower position path with respect to the sensing element of the highest position path.

Title: Process for dissolving radioactive corrosion products from internal surfaces of a nuclear reactor
IPC: G21F9/28
Filed: 1976-05-05
Abstract: A process for dissolving radioactive corrosion products from the internal surfaces of a nuclear reactor. In preparation for reactor refueling, the reactor coolant is depressurized and the temperature reduced to DIFFERENCE 140 DEG F. Hydrogen is purged from the system and the coolant repressurized to about 400 psi to permit operation of a reactor coolant circulating pump. A solution containing oxygen, preferably hydrogen peroxide, is injected into the reactor coolant which is then circulated through the reactor. The thus oxygenated coolant effects prompt and nearly complete release, at least 95% complete, of radioactive corrosion products, especially cobalt 58, from the reactor internal surfaces. The coolant is then circulated through a demineralizer which removes such products by ion exchange processes, at the completion of which, the reactor is opened to commence replacing fuel assemblies in the reactor.

Title: Apparatus for coating glassware
IPC: B05B13/00
Filed: 1978-05-11
Abstract: This invention relates to the art of coating glassware while the ware is moving through an annealing lehr which is provided with a cooling section near the exit end of the lehr. The cooling section is of the continuous recirculation type providing an arrangement for generally cooling the ware to a relatively even temperature even though the ware is moving through the lehr in multiple rows and columns.

A lubricious material in the form of a vapor or mist of an organic, nonmetallic coating material selected from the group consisting of polyolefins, fatty acids and their derivatives is injected into the recirculating cooling air in the cooling section of the lehr to thereby form a durable lubricious coating on the exterior surfaces of the glass article. The articles, at the time they are passed through the cooling section, will be at a temperature between 200 DEG F. and 400 DEG F. The vapor generator used to form the vapor or mist has an outlet tube of at least one foot in length extending vertically from the generating chamber to avoid injection of any condensate into the cooling section of the lehr.
