Title: Protection method for a pressurised water nuclear reactor.
IPC: G21C17/108
Filed: 1979-12-18
Abstract: The invention relates to a method of protection of a pressurized-water nuclear reactor, which enables the crisis of boiling and the melting of fuel to be avoided. An emergency shutdown is triggered when a parameter representative of the crisis of boiling or the power released per unit length of the fuel elements exceeds a limiting value. For the determination of these parameters, the most exact representation possible of the distribution of the power in the core of the reactor is employed. This distribution is obtained by measurement of the axial power by ionization chambers, and determination of the radial power by measurement of the positions of the control rods.

Title: High speed fruit feeding apparatus
IPC: A23N1/00
Filed: 1981-02-12
Abstract: A sequential feeder for rapidly feeding fruit to a sequential citrus fruit extractor includes a plurality of chain conveyors, each conveyor being mounted in a vertical plane extending between a lane of a fruit hopper and a lower extractor cup of the extractor. Each chain conveyor includes a plurality of fingers mounted in uniform intervals thereon.

The guide plate assembly has a sharply curved upper end which causes the fingers of the chain conveyor to pivot rapidly forward after a fruit has been elevated to a height above the associated lower extractor cup such rapid pivoting causes the fruit to be propelled at a high speed into the associated cup. An arched bridge is provided above each conveyor for slidably guiding a fruit as it is elevated from the fruit support to said height above the lower cup and for thereafter guiding the fruit as it is propelled toward the lower cup.
Patent ES-8301752-A1 (ES)
Title: Oriented plastic container
IPC: B29C55/30
Filed: 1981-05-27
Abstract: A container (21), and a method and apparatus for producing the container from a tubular blank of polyethylene terephthalate or similar material, according to which a polyethylene terephthalate blank is stretched at least about 3-fold to produce a preform (20). In an axial section through the preform, the contour length substantially corresponds to the contour length in an axial section through the final container. The preform (20) is heated to a temperature above the glass transition temperature (TG) and is converted to the container (21) in a blow mould (12). In doing so, the contour length of the material is maintained through successive reduction of the axial length of the body (23) which the preform constitutes during the conversion to the container. In order to achieve this, the base portion of the blow mould (11) is moved towards the orifice (22) of the final container. The container acquires a neck portion (23) and a container body (26) which are axially oriented, in the case of polyethylene terephthalate to an extent corresponding to about a 3-fold monoaxial stretching, while the container body (26) is also transversely oriented, in the case of polyethylene terephthalate to an extent corresponding to about a 3-fold stretching as a maximum. The wall thickness of the container is inversely proportional to the radius of the container. The container is dimensionally very stable and has excellent strength characteristics.

Title: Fuse for a secondary projectile.
IPC: F42C15/20
Filed: 1984-08-02
Abstract: The invention relates to a fuse for a satellite projectile that is expelled from a carrier projectile. In order to maintain a defined ignition time within narrow tolerances, despite initial blind position of the fuse immediately after the expulsion of the satellite projectile, the firing pin 7 is centrally arranged in the interior of a key-shaped cover 12 which is movably disposed in the interior of a housing 1. The wall 12' of the cover 12 has a plurality of recesses 5' into which there engage a corresponding number of locking pins 5 mounted on sheet metal springs 4. These springs 4 are radially outwardly swingable and are secured to the housing 1.
