Title: Pilger rolling of hollow billets
IPC: B21B21/04
Filed: 1981-01-27
Abstract: In the initial rolling of a hollow billet 16 the billet (16) is held against axial movement in the feed direction.

Title: Dynamoelectric machine stator wedges and method.
IPC: H02K3/487
Filed: 1982-09-29
Abstract: In a dynamoelectric machine having a rotating field and a stationary stator core, electrical conductors are contained within axially-extending radial slots which are part of the stator core construction. The electrical conductors for stator bars are subject to electromagnetic forces and thermal cycling effects which, over a period of time, tend to cause the stator bars to become loose within their slots. The invention is an improved wedging system which provides both an immediate and residual force on the stator bars which holds the bars in place even after certain settlements have taken place. Further, it is possible to determine the amount of force applied initially to the stator bars by the wedging system and any residual force after a period of operation.

Said detector means comprise two detectors which are disposed in line along a vehicle return path at said entrance and which are so spaced relative to each other as to be capable of being triggered simultaneously by a single member of a vehicle as said vehicle is moved along said path past said detector means, whereby the direction of vehicle movement past the detector means can be determined by the control means.
Patent ES-8405657-A1 (ES)
Title: Boring toolholder for manufacturing mechanical work pieces.
IPC: B23B29/034
Filed: 1983-08-05
Abstract: The invention covers the control of the horizontal position of a reamer cutting tool in relation to a tool-holder pin. A support is surmounted by a core which slides sideways in the pin.

A locking screw locks the support into position once an angle has been fixed. The invention has the following features: reduction in the overall diameter of the tool and increase in precision by the suppression of action which would interfere with the precision adjustment and throw it out of tolerance at the moment the device is finally locked into position.
Patent ES-8500717-A1 (ES)
Title: Freezer.
IPC: F25D3/11
Filed: 1983-10-28
Abstract: A freezer for individually quick freezing foodstuffs such as shrimps, diced chicken and peas, comprises a cooling tunnel (2) for precooling the foodstuff, and a freezing tunnel (3) for freezing the precooled foodstuff.

The frozen foodstuff leaves the freezing tunnel (3) through outlet (14). The ribbon auger (20) is designed to remove the foodstuff rapidly out of the liquid nitrogen and carry it slowly through the remainder of the freezing tunnel (3)-the equalization section.
Patent ES-8503138-A1 (ES)
Title: Signal receptor-reradiator and surveillance tag using the same
IPC: G01S13/75
Filed: 1984-04-24
Abstract: An improved receptor-reradiator, for use in a surveillance system employing a carrier frequency of UHF or higher in combination with a low frequency electrostatic field signal to be modulated on the carrier signal by the reradiator, is provided by an antenna frame wherein the metallic foil of which it is made is divided into three parts. The first part is U-shape of substantially one width and joins to a central portion of substantially reduced width which is predominantly inductive at the carrier frequency. A semiconductor diode, preferably a Schottky barrier diode or PIN switching diode, is connected in said central portion in series therewith. The opposite end of the central portion joins to an enlarged rectangular portion. At the low frequency the component has effectively two capacitive arms, one on each side of the diode, of different surface area to ensure bias signal for the diode. However, at the carrier frequency, the central portion has a high inductive reactance which, in conjunction with the inductive reactance of the U-shape portion, tunes to resonance the total capacitance of the component including that of the diode. The parts are proportioned such that the diode sees at the carrier frequency an inductance on one side and a capacitance on the other side.
