Patent ES-477170-A1 (ES)
Title: Methods of reactor power determination in nuclear reactors
IPC: G21C17/10
Filed: 1979-01-25
Abstract: A method for rapidly and accurately generating an output signal (8) corresponding to the power of a nuclear reactor comprises generating out-of- core neutron flux reactor power signals (2) at different time intervals and utilising predetermined relationships therebetween to adjust a more accurate thermal power signal (1) which has a slow response to transient power conditions. By means of a feedback loop (9), a delayed power signal (3) is fed back to a difference unit (5) to generate a signal in proportion to the difference between the neutron power signal (2) and the delayed power signal (3), which signal is combined with the thermal power signal (1) in a summing unit (4) to obtain a value equal to the instantaneous core power then being perceived by thermal sensors but not immediately available due to the time lag of the thermal response. The output signal (8) is used for reactor control, power limitation or safety shut-down.

Title: Self priming passive dosing dispenser.
IPC: G05D11/03
Filed: 1979-08-13
Abstract: A self-priming passive dosing dispenser for issuing, beginning with the first flush, a quantity of a toilet tank additive solution into a toilet tank as the water is draining therefrom while the toilet is flushing. A preferred dispenser comprises a reservoir for containing a quantity of a toilet tank additive type product and in which reservoir a solid type product can be dissolved to form a product solution. Structure is provided for flooding the reservoir through the discharge standpipe upon initial immersion of the dispenser into the toilet tank water to ensure first flush dispensing of product solution. In steady state operation, while the water in the toilet tank is receding from about the dispenser, a predetermined dose-volume of toilet tank water is vacuum-transferred from a measuring cavity located within said dispenser into said reservoir through an inlet conduit, and a substantially equal dose-volume of the product solution is dispensed through a discharge standpipe. The dispenser may further comprise an internal baffle to precipitate mixing and agitation inside the dispenser which promote dissolution. Upon reaching steady state operation, the dispenser provides an air-lock when immersed in a full toilet tank which air-lock isolates the product and product solution from toilet tank water which surrounds the dispenser during quiescent periods. Plural product co-dispensers which embody the present invention are also disclosed.

Title: Device and a method for withdrawing articles in the form of sheets from a stack of articles
IPC: B65H3/06
Filed: 1981-04-23
Abstract: A device and a method for dispensing articles in the form of sheets from a supply. In order to dispense the articles, for example banknotes, from a supply in the form of a stack of banknotes, the outermost banknote of the stack is first displaced in one direction so that the banknote is made to form a bulge after its resistance to buckling has been overcome, whereupon the banknote is displaced in the opposite direction for being fed out from the dispensing device. The banknote is displaced by means of a withdrawal roller of appropriate shape, wherein the peripheral surface of said roller for example may be concave or convex and/or may be provided with helical projections for affecting the resistance of the banknote to buckling. In consequence of said bulge being formed in the banknote the latter will be effectively separated from the immediately following banknote of the stack, said separation being facilitated additionally by the design of the withdrawal roller.
