Patent ES-275341-A1 (ES)
Title: Load responsive valve
IPC: B60T8/26
Filed: 1962-03-09
Abstract: A valve for a fluid pressure, load-regulated braking system for a vehicle comprises a spring- loaded valve member 1 interposed between a fluid inlet 3 and outlet 5, the spring 6 acting through an end-plate 8 and plunger 10 to urge valve member 1 away from its seat. Valve member 1 is closed at a braking pressure predetermined by the spring loading which is varied by the action of a rod 11. In the construction shown in Fig. 1, the valve is mounted on a bracket 18 of the vehicle loading platform 27. A member 16 pivoted on the bracket at 17 engages at its end a bracket plate 28 of the vehicle axle. The member 16 also carries a spring-loaded pressure plate 13 which, when relative movement takes place between the axle and platform 27 due to loading, varies the pressure exerted on the rod 11 and thus the spring 6. A dashpot device 23, 24 and the spring 14 of the pressure plate 13 damp oscillations due to the vehicle moving over uneven ground. In a further embodiment (Figs. 5 to 9, not shown), the valve is secured to the chassis of the vehicle which has independent suspension. A spring-loaded telescopic member surrounding and secured to the compression tube of the suspension engages a stirrup member 54 (not shown) pivoted about the chassis, a tappet screw 52 (not shown) of the stirrup member 54 (not shown) engaging and actuating rod 11.

Abstract: Large hollow articles i.e. articles having at least two dimensions greater than 10 inches are rotationally cast in a process which involves: (a) Providing in a metal mould a liquid charge comprising epsilon caprolactam and an anionic catalyst and catalyst promoter for its polymerization, the charge being heated to 140-180 C. and kept under a dry inert atmosphere while in the mould, the charge being a mixture which when polymerized at 140-180 C. increases in viscosity from 10 to 100 centipoises in 1 to 3 minutes and from 1,000 to 10,000 centipoises in 1 to 6 minutes, from 100 to 400 centipoises in not more than 2 minutes at 150-180 C., the charge being sufficient to form a layer of average thickness between 10 and 100 mils. (b) Closing the mould and rotating it at a rate of between 1 and 20 r.p.m., until the liquid charge has been distributed over all the surface this being accomplished while its viscosity is less than 10,000 centipoises. (c) Heating the mould at 150 to 175 C. after the completion of step (b) until the polymer has crystallized to at least 20% crystallinity, this step taking 3 to 30 minutes and its end being marked by contraction of the hollow object away from the walls. (d) Providing within the hollow article another liquid charge of the same composition of the first under a dry inert atmosphere, rotating the hollow article either alone or in the mould under the same conditions as in (b) to form a second layer in the hollow article and heating the mould as in (c) to crystallize this layer. The successive layers preferably have an average thickness of not more than 70 mils and the whole process lasts not more than 20 minutes. The mould may be rotated about two intersecting axes, the angular rotation rates about these axes being in the ratio between 2 and 5:1. The anionic catalyst may be a reaction product of lithium hydride and epsilon-caprolactam and the promoter a polyfunctional (trifunctional or higher) compound, preferably a trifunctional triazine.

Title: Record player
IPC: G11B19/12
Filed: 1967-09-20
Abstract: In a record-player including a turntable (42), an electric motor (24), a tone arm (7) pivoting about a vertical spindle, and a control disc (17) driven by the motor (24) to control the movements of the tone arm (7) in accordance with the diameter of the record to be played, this diameter being determined by means of a feeler (43) integral with the tone arm (7), the turntable starts rotating only after the diameter of the record has been determined and when the feeler is no longer in contact with the record. This is effected by virtue of the control disc's provision of a peripheral cam track (29) which controls the movements of an idler wheel (35) for transmitting the motor drive to the turntable.

Title: Hermetically sealed dynamoelectric machine
IPC: H02K9/20
Filed: 1971-12-30
Abstract: Effective spray cooling of the stator of a hermetically sealed motor is achieved without a reduction in stator flux carrying capacity by passing fluid refrigerant through triangularly shaped axial channels situated entirely within the stator teeth. Desirably, the edges of the channels are disposed parallel to the tapered faces of their associated teeth and the flux carrying area of each tooth is equal to the flux carrying area of the tooth face confronting the motor air gap. In one embodiment of the invention, entry of fluid refrigerant to the axial channels within the teeth is accomplished utilizing a diversely apertured annular manifold centrally positioned along the stator core and the refrigerant is withdrawn at both ends of the motor. Other refrigerant flow configurations, e.g., admitting the refrigerant at both ends of the motor and exhausting the refrigerant at the center or both ends of the motor, also are described.
