Patent ES-357259-A1 (ES)
Title: Equipment for monitoring the radioactivity of coolant in a nuclear reactor
IPC: G21C1/03
Filed: 1968-08-14
Abstract: Failed fuel assemblies in a sodium-cooled fast reactor (Fig. 6, not shown) are detected by connecting each assembly by an individual sample pipe to a detecting apparatus, the pipe supplying to the apparatus a sample of the sodium coolant which has flowed through the associated fuel assembly. The detecting apparatus (Figs. 1-5, not shown) includes a motor-driven conduit which is sequentially connected in turn to each of the sample pipes, the conduit being associated with a set of delayed neutron detectors connected via amplifiers to recording equipment. Also, a larger diameter, stationary, conduit receives the combined samples from all the sample pipes, this larger conduit being associated with a further set of delayed neutron detectors. The detecting apparatus thus provides for continuous sampling of the fuel assemblies individually simultaneously with and independently of the continuous sampling of all the fuel assemblies in bulk. As shown, the neutron detectors are of the boron trifluoride type.

Title: Liquid metering wheel
IPC: G01N1/12
Filed: 1969-06-26
Abstract: A device for continuously delivering measured quantities of liquid comprises, a vessel 2 having two compartments 5, 6 each having a weir overflow 8, 10 and a wheel 13 revolvable with a hollow spindle 14 having a cavity 16 extending around half the circumference and the other half of the wheel being reduced in volume by half the volume of the cavity to form a solid section 19. The spindle 14 is mounted in a bearing 15 in a fluid tight manner and is connected with the cavity 16 by a radial passage 17. The spindle axis and weirs are all at the same level. The spindle 14 may have a toothed wheel 21 for rotation by a motor One end of the cavity 16 is connected with the compartment 6 by an opening 18, and the other to the interior of the spindle by a passage 17. Whilst this opening 18 is above the level of the liquid in the compartment 6, Fig. 7, during rotation of the wheel (anti-clockwise as shown), the cavity 16 is filled with liquid from the compartment 5, the additional volume of the portion of the wheel containing the cavity 16 over the portion 19, serving, as it is being immersed, to displace a volume of liquid equal to the one half, of volume of the cavity over the weir 10. When the opening 18 is immersed, Fig.4, the liquid in the cavity 16 flows into the compartment 6, over-compensating for the reduced displacement of the portion 19 then being immersed by one half of the volume of the chamber 16, This half also flows over the weir 10. Thus the volume of the cavity 10 is discharged on each revolution.

Title: Steam power stations
IPC: F01K3/02
Filed: 1973-07-13
Abstract: The steam power station includes an accumulator for storing heat drawn from the operating steam cycle during slack operating periods when the power network demand on the station is low, and restoring the heat to the steam cycle at peak or high-demand periods, to adapt the station to a variable demand network. The transfer of heat between the operating installation of the station, which includes a steam turbine, and the accumulator, is made by way of a heat-transfer fluid which is in heat-transfer relation with the steam of which at least a part has done mechanical work in the turbine. The heat-transfer fluid is reversibly circulated in heat-transfer relation with the steam in such a way that the heat-transfer from the steam to said fluid occurs at substantially the same temperature as the transfer from said fluid to the steam. The installation can also heat feed water returning to the steam generator by tapping off live steam for said heating at the outlet from the generator. The installation can have apparatus for separating into liquid and dry steam partially expanded steam issuing from the turbine, the liquid from that apparatus being vaporised by heat from a heat accumulator supplied with heat from the heat source of the installation all the liquid is vaporised during high-demand periods while in slack periods all the liquid is restored to the feed water circuit to the steam generator.

Title: Apparatus for cutting open a fowl
IPC: A22C21/06
Filed: 1976-10-30
Abstract: A revolving apparatus for automatically cutting open fowl hanging by the ankle joints from an overhead conveyor, having a number of cutting units regularly spaced about the circumference of the apparatus. The cutting units work in succession as they revolve about the central shaft of the apparatus moving along with the conveyor. Each cutting unit is also vertically movable down towards a fowl carried by the conveyor and away again from the fowl. Each cutting unit carries a ball shaped protrusion consisting of two separatable ball halves, one of which carries a knife in its upper part facing away from the other ball half. During the downward movement of each cutting unit it's closed ball halves are inserted into an opening in the fowl previously made by cutting out it's vent, whereafter the ball halves are spread and the fowl is cut open by the knife. The penetration depth of the ball halves is automatically adapted to the size of the fowl by means of an abutment member carried by each cutting unit and gripping between the fowl's legs.

Title: Preparation of pizza cheese
IPC: A23C19/068
Filed: 1976-11-17
Abstract: Low-moisture mozzarrella (pizza cheese) is prepared using a standard starter culture plus an additional culture selected from Pediococcus cerevisiae, Lactobacillus plantarum, Streptococcus faecalis, Streptococcus durans, and Lactobacillus casei, or mixtures thereof. Although the cheese is made by the usual processing steps, the cheese product has a reduced lactose sugar (and/or its monosaccharide derivatives) content due to the added culture, which metabolizes residual lactose during a cold temperature holding at the end of the process. The resulting cheese has improved properties for the manufacture of pizza, being substantially nonburning and having improving melt, flavor, and color characteristics.
