Title: Improvements in and relating to the detection of defects in transparent or translucent containers
IPC: G01N21/90
Filed: 1963-12-05
Abstract: In an arrangement for detecting faults in hollow containers of transparent or translucent material and for rejecting those found to be defective, the containers (bottles) which are successively fed to a test position by a star wheel are rotated during testing, a beam of light is focused on or in the wall of the container, and a wide area sensing device is provided together with an apertured block of "micarta" (Registered Trade Mark) which provides a plurality of paths by which radiant energy reflected by a fault may pass to the sensing device. The wide area sensing device may comprise a group of parallel connected silicon cells and the lines of the paths are arranged to intersect at the focal point of the beam in the wall of the container. The test position may have two such arrangements applying light from a filament lamp at 45 degrees to a horizontal plane and 45 degrees to a vertical plane respectively, a mask being provided to prevent mutual interference.

Patent ES-335020-A1 (ES)
Title: A Method for Purifying Carbon Dioxide Gas
IPC: C01B32/50
Filed: 1966-12-28
Abstract: Carbon dioxide which is used as a coolant in a graphite-moderated nuclear reactor and to which a small proportion of methane has been added to inhibit corrosion of the graphite, is purified by converting the water content to H 2 by reaction with CO, eliminating H 2 by diffusion, and oxidizing CO to C0 2 with oxygen. The reaction between H 2 O and CO may employ a Cu-Zn catalyst, and the oxidation of CO to C0 2 a Pt, Pd, Cu, or copper oxide catalyst. Diffusion of the H 2 takes place through tubes made of Pd alloy into another circuit containing C0 2 in which the H 2 is catalytically oxidized to H 2 0 which is removed by condensation. Reference, has been directed by the Comptroller to Specification 1,108,512.
Patent ES-336618-A1 (ES)
Title: Force limiting tool
IPC: H01R43/00
Filed: 1967-02-09
Abstract: A staking tool comprises a tool body, a tool head movable relative to the tool body against a first spring to cause the tool head to apply a first force to the workpiece, a force applying member acting through a second spring to cause the tool head to move further relative to the body to apply a second force to the workpiece and sensing means responsive to the relative movement between the tool head and the tool body to render the force applying member inoperative upon the first and second forces reaching a predetermined aggregate value. The tool is used to insert stakes 84 into eyelets 82 in an insulating panel 80 to trap electrical heads (not shown) between the stakes and the eyelets. A base 10 and column 12 support a bracket 14 on which is mounted an air cylinder 16, the piston rod 22 of which is connected to a tool body 24. A plunger 54 is slidable inside the tool body 24 and is biased downwardly by a spring 58. An extension 28 of the tool body 24 guides a carrier 42 on which the staking head 52 is mounted. The staking head is downwardly biased by a spring 48 between the upper end of the carrier and a capnut 38 which screws into the extension 28. A rod 46 projecting upwardly from the carrier 42 completely fills a corresponding bore in the plunger 54 when the spring 48 is compressed as shown in Fig. 4. When there is no obstruction to its movement the carrier 42 is moved downwardly by the spring 48 until collar 44 abuts the shoulder 50. A micro-switch 64 is fixed to the tool body 24 and a switch-operating rod is carried by a lifting hook 66 attached to the carrier 42. Operation.-The hook 66 is lifted and the panel 80 moved to bring a stake 84 under the staking head 52. When the hook is released the spring moves the head 52 on to the stake with a force of up to 2 1bs. The air cylinder is then operated to move the entire tool body downwardly. If the spring 48 is not fully compressed then the carrier moves up into the extension 28, the spring 48 compressing until the rod 46 bottoms in its bore. At this point there is a gap " X " between the rod 68 and the micro-switch 64. Further movement of the piston-rod 22 causes the plunger 54 to move against the spring 58, until the rod 68 operates the micro-switch 64. The force necessary to deflect the spring 58 by the amount " X " is 10 lbs., so that the total force on the staking head 52 is 12 1bs.

Title: Device for deriving a measuring voltage induced by the rotor of an electric motor
IPC: G01P3/46
Filed: 1969-04-28
Abstract: A voltage dependent upon the speed of a motor and derived from a winding on the magnetic circuit of the motor is compensated for the effects of the armature current by means of a transformer 28. The Specification describes the use of such a transformer with several types of motor. In Fig. 1 the motor has a permanent magnet rotor 1 driving an interrupter contact 2 controlling transistors 12, 13 supplying pulsed D.C. from a source 10 to stationary armature windings 7, 8. The transistors 12, 13 are controlled by transistor 17 according to the difference between a reference voltage across Zener diode 18 and a rectified and smoothed voltage derived from an additional winding 9. A secondary winding 27 of the transformer 28 is in series with winding 9 the primary windings 25, 26 are in series with the armature windings 7, 8 so that the voltage from winding 9 is reduced by an amount dependent upon armature current. Fig.2 (not shown) illustrates a modification in which there is only one armature winding 7. In Fig. 3 (not shown) the invention is applied to a series wound commutator motor the primary of the transformer being in series with the motor and the secondary in series with the output of a bridge circuit detecting the back e. m.f. of the armature. In Fig.4, a three pole motor, which may be an induction motor or have an energized rotor 41 (not shown), has three energized windings 48, 49, 50 and three speed-detecting windings 51, 52, 53 each connected in series with the secondary of an individual transformer 58 to provide a three phase output 61 which may be rectified to provide the speed voltage. In a high speed motor Fig. 5 (not shown) windings 51-53 are replaced by single winding on the core (at 44") the transformer has two primaries in series with windings 47,49 respectively.
