Patent ES-342777-A1 (ES)
Title: Ball cock
IPC: E03D1/32
Filed: 1967-06-22
Abstract: A float valve, for maintaining the level of liquid in a container 24 such as a toilet flush tank comprises an inlet member secured to the tank and having parts 42, 48, 50 and 52, a easing member 54 surrounding the inlet member and having mounted at its top end the lower part 58 of a valve housing, this part having removably attached to it the valve housing upper part 80 which carries a guide 34 along which is movable a float (32) all parts except the inlet member which is metallic, being of plastics material, and all parts being held by the inlet member whose portion 52 is contained within a similar portion 56 of the lower housing part 58. Between the two housing portions there is held a resilient sealing member 82 comprising an outer stationary part 100, an intermediate movable part 96, and a central stationary part 92, the parts being interconnected by narrow flexible portions 98 and 94 with the intermediate portion 96 being movable towards and away from a seat 86 formed on the housing 58. A pin 84, formed with bands of varying diameters, some of which carry grooves, is movable within a bore formed in the central part 92, which bore communicates via radial openings (114) with a chamber 108. With the pin in the position shown, to which it is moved, via links 38, 36, by the float when in its uppermost position, fluid from the inlet member 42 passes, through the bore and radial openings, into chamber 108 thereby forcing part 96 on to its seating 86. With the float lowered, i.e. with the pin raised from the position shown, fluid flow to the chamber is stopped and fluid within this chamber is forced, by inlet fluid pressure acting on member 82, to the container 24 via opening 128 thereby permitting part 96 to rise from its seating. This then allows fluid from the inlet to flow across the seating 86, through apertures 60 and into chamber 70 from where it enters chamber 72, via axial passages (74), and hence, via circumferential passages 78, passes into the container 24. The disposition of the pin when in either of its two positions, together with the grooves formed on the pin, serve to substantially eliminate the ingress of solid material into the interior of chamber 108, any solid material contained in the liquid flowing from the inlet member, through apertures 60 and finally passage 78, being deposited in the casing member 54 from which it can be readily removed.

Title: Anti-slip or anti-skid devices for rail vehicles, in combination with rail cleaners or rail brakes and switch means
IPC: B60T8/00
Filed: 1969-08-14
Abstract: An anti-slip or anti-skid device, which device in use acts on slipping or skidding of a wheel set, on associated braking or driving means to decelerate or accelerate the wheel set, is combined with switch means in the form of an electromagnetic valve 15 which is controlled by the anti-slip or anti-skid device and by which valve 15 a head section 3 of a rail cleaner 2 is moved from a rest position and temporarily held in an operating position to clean a rail surface 12. As shown, the valve 15 is connected to the anti-slip or anti-skid device (not shown), by an electric line 16 and the valve 15 is situated between a pressure medium pipe 14 and a pipe section 141, which pipe section 141 connects with the rail cleaner 2 which is pressure-operable and comprises the head section 3, e.g. a rubber plate at the lower end of a piston-rod 4 which has at its upper end a piston 5 situated in a cylinder 6. The piston-rod 4 has fixably attached thereto within the cylinder 6 a plate 8 and between the plate 8 and the bottom 7 of the cylinder 6 is situated a spring 9 and a quantity of damping liquid 10, the distance h corresponding approximately to the spacing of the head section 3 from the surface of rail 12 in its rest position. Opening of the valve 15 by the anti-slip or anti-skid device results in the flow of pressure medium from the pipe 14 to the pipe section 141 via a by-pass pipe 20 containing an open check valve 21 to thereby move down the piston 5 and bring the rail cleaner 2 into its operative position: on the valve 15 closing the pipe section 14 becomes connected to an outlet 17 but the return movement of the piston 5 is slowed down by a timing means comprising a pressure medium reservoir 18, the check valve 21 in the by-pass pipe 20, which valve 21 now closes, and a throttling device 19 in the pipe section 141 which throttling device 19 slows down the return flow of pressure medium.

Title: Electrical drive systems for sewing machines
IPC: D05B69/18
Filed: 1969-12-02
Abstract: A sewing machine is driven by a motor having a low-inertia armature and a constant field, means being provided for selectively, controlling the armature. A treadle 23 is depressed to adjust tap 45 of potentiometer 44, capacitors 58, 59, 60 being charged in sequence until the respective silicon unilateral switch 64, 65, 66, becomes conductive to trigger the associated silicon controlled rectifier 53. The armature 12 is then energized whereby the motor rotates and produces a back E.M.F. on lines 54, 57, which is in opposition to the voltage on the capacitors with respect to the anode-cathode voltage on the switches 64, 65, 66. The conduction angle of the rectifiers is thus adjusted for operation of the motor at a stable speed. The potentiometer 44 may be replaced by a set of switchable resistors. The firing angles for the three supply phases may be matched by adjusting resistors 61, 62, 63. When the treadle is heeled, switch 51 closes to transmit a pulse through capacitor 72 to the gate of rectifier 74, the tap 45 being at the zero position. A braking resistance 76 is then connected across the armature until the motor approaches standstill and the rectifier 74 is turned-off.

Title: Preparation of zearalanone or of racemic mixtures of zearalanol diamers
IPC: C07D313/00
Filed: 1973-01-12
Abstract: Substantially colorless zearalanone is produced from zearalanol, for example from the low melting diamer of zearalanol, by (1) blocking the phenolic hydroxyl groups of the zearalanol, e.g., by converting them to acetate groups, (2) oxidizing the blocked zearalanol to blocked zearalanone, and (3) removing the blocking groups from the blocked zearalanone to obtain substantially colorless, unblocked zearalanone. Alternativly, the blocked zearalanone can be directly reduced to a high purity mixture of high and low melting diamers of zearalanol.
