Title: Torque converter and clutch
IPC: F16H45/00
Filed: 1968-03-06
Abstract: In torque transmission apparatus in which an hydraulic converter assembly 30, Fig. 1, is arranged in series with a friction, clutch coupling assembly 32 the cross-section of the converter toroidal blade system 124 is an oval having its minor axis parallel to the converter axis, the converter output shaft 94 is supported in a bearing extension 36 of a partition (34), Fig. 2 (not shown), which protrudes in the central space of the blade system 124 with at least one bearing 110 accommodated in the axial zone of the blade system and the friction clutch coupling assembly, which has a diaphragm spring 196, is released by axial movement of a bearing 210. Hydraulic converter.-An engine drives the pump wheel 40 through shaft 66 and driving shell 52, the pump wheel being mounted on the bearing extension 36 by means of a bearing box 48. The shell structure 54 carries a toothed rim 62, e.g. for engagement with a starter, and a ring 160 having cooling channels (162), Fig. 2 (not shown). The impeller wheel 72 is also mounted on the bearing extension 36 by means of a slip coupling 74, splines 78 and a bearing box 110. A sealing disc 84 on the slip coupling 74 engages via needles 86 on the hub part 44 of the pump wheel 40. The turbine wheel 116 is mounted via splines 112 on a hub 108 supported on shaft 94 within the bearing box 110. Blades 68, 90, 120 are fixed by securing lugs (158). Pressure fluid system.-Chamber 126 is filled with pressure oil via pipe 128, boring 130, pipe 132, borings 134, 136, annular channel 152, boring (142) through needles 86. The return flow is via conduits 144, axial boring 146, radial boring 148, annular channel 150 to borings (154,) (156) and thence to an external circuit (not shown) similar to the supply system. In operation the pressure oil flows in the direction of arrow "A" within the blade system. Friction clutch.-The converter output shaft 94 carries a coupling base-plate 165 which mounts a housing 188 for the diaphragm spring 196 which has radial torque (204) at its inner edge and acts on a contact pressure ring 194. Laminated tangential springs (192) prevent the pressure ring 194 from rotating relative to housing 188. Torque is transmitted through friction linings 184, 186 to a clutch disc 170 carried via splines 176 on an output shaft 174. The clutch is disengaged by rotation of pivot shaft 226 which moves the bearing 210 axially by means of interengaging hooks 222, 224.

Title: Improvements in or relating to Worm Gearings
IPC: F16H55/22
Filed: 1968-10-03
Abstract: In a worm gearing comprising a globoidal worm 3 and globoidal worm-wheel 1, the wormwheel 1 is of steel hardened and ground on the surfaces of its teeth 2 which co-operate with the worm 3 which is produced from a softer material than the wheel 1 such that any manufacturing variations in tooth pitch &c. between the worm and wheel are accommodated by the softer teeth on the worm adjusting its form (i.e. wearing away during running in) to the form of the harder teeth 2 on the wheel 1. The worm 3 may be of unhardened steel, bronze, cast iron or aluminium or may be of steel, hardened to a lesser degree than the wheel 1. The grinding of the tooth flanks of the wheel 1 may be effected by a cylindrical hobbing worm of equal size and pitch, the grinding worm being coated with an abrasive composition and trued according to the pitch and form of the worm-wheel teeth, which teeth may be of involute form or of trapezoidal cross-section. A hardened and ground globoidal worm-wheel may alternatively be used with a soft cylindrical worm, the worm in operation assuming a form approximating to that of a globoidal worm.

Title: Method and apparatus for magnetically treating eggs and animal semen
IPC: A01K45/00
Filed: 1974-10-03
Abstract: A method of treating semen from male fowl to increase the production of fertile eggs by female fowl inseminated with the treated semen by exposing the semen to a magnetic field of predetermined intensity and for a predetermined period of time. The semen so treated increases the number of fertile eggs produced by the female fowl inseminated with the treated semen. The invention also includes a method for treating fertile eggs to increase the hatch rate and the rate of growth of fowl hatched from the treated eggs. The eggs are treated by placing the eggs in a magnetic field of predetermined intensity to expose the eggs to the magnetic field and then removing the eggs from the field after a predetermined period of time. Preferably, the magnetic treatment of the eggs is done prior to incubation. The invention also includes apparatus for magnetically treating eggs, vials of animal semen, or other fragile articles, such apparatus including a magnet for producing a magnetic field and supporting means of soft resilient material extending through the magnetic field for supporting articles moving through the magnetic field. The apparatus may also include means for revolving the eggs, vials of semen, or other articles, as they move through the magnetic field to constantly change the orientation of the article with respect to the magnetic field during the time that the article is being treated in the magnetic field.

Patent ES-437653-A1 (ES)
Title: Multiple particle type interaction isotopically selective ionization
IPC: H01J49/10
Filed: 1975-05-13
Abstract: Method and apparatus for impact ionization of particles excited with isotopic selectivity, particularly for use in a system of uranium isotope separation and enrichment. Efficient impact ionization is achieved by first selectively exciting vaporized particles of the desired isotope in a beam of finely tuned laser radiant energy. The energies of the interacting photons are selected to produce a total energy shift during excitation which is slightly less than the ionization energy for the selected isotope. The excited isotope will thus be raised to an excitation level only slightly below the ionization level. This level is selected to permit efficient ionization, particle collisional ionization, between energetic particles in the uranium vapor environment and the highly excited particles of the desired isotope type.

Patent ES-477278-A1 (ES)
Title: An apparatus for forming glassware.
IPC: C03B/
Filed: 1979-01-30
Abstract: This invention concerns a timing pulse generator for a glassware forming machine which has a large number of individual sections, each of these capable of shaping glassware from gobs of molten glass. A gob distributor supplies the gobs to the individual sections at a predetermined rate proportional to the speed of a gob distributor drive motor. The speed of the drive motor is determined by the frequency of the alternating current power generated by a power source such as an inverter drive. Thus, the cycle time of each individual section and, therefore, the cycle time of the machine, are determined by the gob distribution rate.
