Patent ES-359799-A1 (ES)
Title: Tape winding machine
IPC: B65H23/02
Filed: 1968-10-31
Abstract: To prevent a tape from being crushed by the trailing edge of a traversing device 10 of a package winding apparatus, the tape is fed over at least one guide member 8 that alters its setting relative to the take-up spindle 4 so as to bias the tape 2 to move readily from the centre of the package towards its ends but adapts a fresh setting when the tape is moving from the ends of the package towards the centre of the package, said fresh setting causing a lesser degree of bias or even negative bias to retard movement of the tape sideways. In Fig. 1 the guide member is a round bar 8 in the form of a shallow V pivoted at 14. The tape 2 engages the underface of the bar 8. The bar 8 is rocked by a piston and cylinder unit 56 controlled by co-operating means 52, 54 and 53, 55 on the traverse mechanism. When the tape is returning from the left-hand end of the package the bar 8 is in the full line position with its arm 18 horizontal or slightly sloped downwardly towards the pivot 14. The other arm 181 of the bar slopes upwardly. When the tape is returning from the right-hand end of the package the unit 56 operates to rock the bar to the broken line setting in which the arm 181 is horizontal or slightly sloped downwardly towards the pivot 14 and the other arm 18 slopes upwardly. Stops 62 define the desired settings of the bar 8. The guide member may be between the traverse member and the package. In a modified construction the guide member comprises two wings mounted on an axis parallel to the spindle 4, the guide member pivoting back and forth in a radial direction to substitute one wing for the other at the ends of the traverse movement, the wings being shaped to give a different degree of bias to the tape during traverse from and to the ends of the package. Traverse mechanism.-The traverse device 10 is coupled to a nut 22 on a traverse screw 24. The screw 24 is driven from a shaft 30, see also Fig. 3 (not shown), through gearing controlled by a piston 42. When the components 52, 54 co-operate the piston 42 rocks a bracket 38 to a setting in which the gear 44 is driven by gear 32 via gear 34. When the components 53, 55 co-operate the piston 42 rocks the bracket 38 to a setting in which the gear 34 moves away from the gear 44 and a further gear (40) driven by the gear 34, engages gear 44.

Title: Unscrambler
IPC: B67B1/00
Filed: 1972-01-14
Abstract: A sorting device or unscrambler comprising a pair of elongate parallel rod members positioned and held at a slope downward from the input station thereof to a delivery station.

Title: Rack and pinion assemblies
IPC: F16H57/022
Filed: 1975-11-14
Abstract: Rack and pinion assemblies employ a bearing assembly which is provided for rotatably mounting the pinion member in a housing member, the bearing assembly comprising three generally annular bearing elements which substantially encircle the pinion member. A first of the bearing elements is carried by one of the pinion or housing members and the second and third of the bearing elements are carried in an axially disposed relationship by the other of these members. The first element has a first bearing surface which engages axially between and slidably abuts substantially complementary second and third bearing surfaces of the second and third elements, respectively. The area of abutment between the respective surfaces extends both radially and axially so that the abutment restrains both radial and axial displacement of the first bearing element relative to the other two. The bearing assembly may be mounted in the rack and pinion assembly on a piecemeal basis, or may advantageously be provided as a pre-formed, pre-loaded unit whereby loading adjustments do not depend upon the skill of an operator during assembly of the rack and pinion.

Title: Anti-burglar mini-radar
IPC: G01S13/56
Filed: 1976-03-25
Abstract: An anti-interference Doppler effect mini-radar includes a generator of pure microwaves, and a receiver for receiving reflected microwaves and coupled to the generator for detecting and demodulating the transmitted and reflected microwave signals. The demodulated signals are applied to a gain controlled preamplifier, and thence to an adjustable gain amplifier. The output of the adjustable gain amplifier is applied to an alarm control circuit. In order to adjust the gain of the preamplifier a servo-circuit is responsive to the input of the alarm control circuit for applying a gain control voltage to the gain control terminal of the preamplifier. A timing circuit responsive to the output of the adjustable gain amplifier blocks the servo-circuit and inhibits the operation of the alarm control circuit for a determined time following the sudden increase in the output of the adjustable gain amplifier.

Title: Monitoring chemical reaction photoelectrically
IPC: G01N35/02
Filed: 1978-06-19
Abstract: Portions of a plurality of different samples are inserted automatically into an array of cuvettes which is advanced continuously or preferably intermittently along a circular path. Photometer means, preferably having several photometric detectors, are mounted in fixed orientation on a common support that advances rapidly compared with the movement of the cuvettes along a concentric circular path, such that radiation passing through each of the cuvettes is monitored many times by a specific photometric detector by the time that cuvette completes one circuit of its path. The photometric detectors can operate at several different wavelengths. Many different chemical reactions can be monitored at the same time. Detector signals are converted into digital signals proportional to absorbance and transmitted from the moving assemblage to a stationary receiver, e.g. as a pulsed train of light signals or by slip rings.
