Title: Method of production of plastic lenses with aspherical surfaces
IPC: B29D11/00
Filed: 1967-02-14
Abstract: A method of production of plastic lenses with aspherical surfaces, such as contact lenses, comprises heating an essentially unswollen, mechanically workable polymer with a plastic memory which is then deformed and cooled in its deformed state, in which state it is mechanically worked by rotationally symmetrical, preferably spherical, cylindrical or conical, surfaces, and then is relaxed by further heating to a free state of internal stress. The material of the lens is a cross-linked polymer and may be deformed mechanically or by gas or liquid pressure. The lens may be deformed and ground so as to be spherical and after reheating relaxes to have an aspherical shape. If the lens is a hydrophilic contact lens, the relaxation may be effected by swelling in water or alcohol. The lens may be for cameras, spectacles and the like.

Abstract: In a method for separating mercury amalgam from contaminants and liquid lying on its surface, in apparatus for the electrolysis of brine using a mercury cathode, the mercury or mercury amalgam, contaminants, and liquid are caused to flow together through a first narrow duct means 6, the mercury or mercury amalgam being caused to pass under and past a 'baffle 7 into a further duct means 8 which is parallel and in side-by-side disposition with the first duct means, the baffle forming a common, partial side wall between the ducts and having an opening thereunder and below the upper surface level of the mercury or mercury amalgam so as to permit passage only of the mercury or mercury amalgam through the opening and blocking passage of the contaminants and the liquid. Fig. 1 shows apparatus where Hg flows into and across an electrolytic cell 1 from an inlet space 2 and amalgam, contaminants and electrolyte flow from the cell through a passageway 4. A baffle 7 separates the contaminants and electrolyte from the amalgam which then passes through a denuder 9. The resultant Hg is pumped at 10 through a duct 11 where it is washed with water supplied at 14. A baffle 12 separates the Hg, which returns to the electrolytic cell 1, whilst the water is passed to the denuder 9 by a pipe 16. Fig. 12 shows apparatus comprising an electrolytic cell 52 with a mercury inlet passage 51 and an outlet passage 53, a chlorine gas barrier baffle 54, a baffle 56 for separating contaminants and electrolyte from amalgam, an amalgam duct 57, denuding tower 58, a mercury path 59 fed with wash water at 60, a pump 61 pumping the Hg and water through a duct 62 to the head of the electrolytic cell, a baffle 63 separating water from the Hg which is supplied to the cell inlet passageway 51, and a weir 64 separating contaminants and a small quantity of Hg from the water which is returned by path 65 to the amalgam duct 57. Figs. 9 and 10 (not shown) illustrate parallel ducts (31, 33) with a baffle (32) therebetween. Downstream of the baffle (32) within the duct (31), there is a weir (34) and baffle (40) whereby contaminants (39) can be separated from electrolyte or wash water (38).

Title: Method of carbiding tantalum or tantalum alloy and filament
IPC: H01K1/26
Filed: 1968-12-13
Abstract: Thin members of tantalum metal or alloy principally comprising tantalum are joined together and simultaneously carbided by heating to at least 1800 C. in an atmosphere of carbon, nitrogen and inert gas until the members display the gold colour of substantially stoichiometric tantalum carbide. The volume ratio of nitrogen to inert gas in the heating atmosphere is 10/90 to 60/40. The temperature should be maintained at less than that required to melt the material, about 2500 C. Members up to 50 mils thick may be carbided and joined by this method. The invention also provides a process whereby previously carbided relatively massive members of refractory metals may be joined. A sheet or powder of tantalum is placed between the members and they are heated as above until the tantalum sheet or powder displays the gold colour of stoichiometric TaC indicating that the massive carbided members are joined.
Patent ES-382216-A1 (ES)
Title: Telecommunication system
IPC: H04M13/00
Filed: 1970-07-27
Abstract: A timing station provides time division multiplex channel signals on a first closed loop unidirectional transmission line interconnective in tandem subscriber stations, each of which may gain access to an unused channel signal for communication with an idle subscriber station. To protect against failure of the entire system due to a break in the line or failure in one of the subscriber stations, a second closed loop unidirectional transmission line is connected to all stations transmitting signals in a direction opposite to that on the first line. Each subscriber station can detect an error and transfer the communication signals on the first line to the second line. The subscriber station before the break transfers the communication signal to the second line and the subscriber station after the break transfers the communication signals back to the first line to form a new, but continuous closed loop. When communication signals are on the second line and a fault occurs, the transfer of communication signals will be similarly performed to provide still another new, but continuous closed loop by passing the fault. Two embodiments to detect a fault and control the transfer of communication between the two lines are disclosed.

Title: Modular in-core flow filter for a nuclear reactor
IPC: G21C3/32
Filed: 1975-04-30
Abstract: A modular in-core flow filter for capturing potentially harmful debris during cold hydrostatic and hot functional testing of a nuclear reactor. Since testing is carried out before fuel assemblies are placed in the reactor, multiple filters, each being of the same size and configuration, are temporarily installed on the reactor lower core plate. They fill the space which later is occupied by fuel assemblies when the assemblies are installed in an operating position. Each filter includes a square metal base having a single axial opening which desirably covers four holes in the core plate. Fine mesh and coarse mesh screens are secured in the axial opening and the unit is removably attached to the core plate by brackets which extend through the metal base and engage the underside of the core plate but are actuated into position from the upper side of the core plate. When functional flow testing of the primary coolant system has been completed, the filters are removed for subsequent use in other reactors. Any debris caught by the screens and in the bottom of the presssure vessel is removed and the fuel assemblies are then loaded into the reactor.
