Title: Cup seal member for the pistons of hydraulic master cylinders
IPC: F16J15/32
Filed: 1969-05-03
Abstract: The piston 14 of an hydraulic master cylinder 10 having circumferentially spaced fluid compensating passages 34 therein is packed by a resilient cup seal 22 formed in its face abutting the piston with an annular recess 40 aligned with the passages 34.

Title: Automatic mechanical device for doffing and loading spun yarns in spinning frames,doubling frames and the like
IPC: D01H9/04
Filed: 1969-07-07
Abstract: Each spindle of a spinning frame is associated with a plate 22 vertically slidable on a member 11 and connected to a chain 19 so that rotation of a pinion 17 causes plate 22 to move vertically. Mounted to rotate about a shaft 35 supported by plate 22 is a box member 24 which has pivoted to it a polygonal full package gripper 28. Also mounted in box member 24 is a horizontally slidable tube 31 carrying a vertical tube 32 in which an empty package tube 39 can be carried. During spinning, member 24 and holder 28 are in the position shown in Fig. 6. To commence the doffing operation plate 24 is raised to the top of member 11 and is stopped. Box member 24 is rotated through 180 anticlockwise, see Fig. 7 not shown, so that holder 28 is positioned vertically above the full package 36. Plate 22 is then lowered until holder 28 encircles package 46. Tube 31 is then moved through a short distance to allow holder 28 is pivot into contact with the full package and to move tube 32 so that the package is clamped between a resilient portion 29 on holder 28 and a similar portion on tube 32. The package is then raised, pivoted over the top of member 11, lowered and released into a receptacle. To don the empty bobbin in tube 32 the operation is repeated but horizontal tube 31 is moved through a distance such that the empty bobbin tube is aligned directly over the spindle.
Patent ES-370929-A1 (ES)
Title: Improvements in or relating to supply and ignition circuits for electric discharge lamps
IPC: H05B41/04
Filed: 1969-07-30
Abstract: A discharge lamp starting circuit includes a bi-directional semi-conductor element which is triggered so as to discharge a capacitor. The pulse produced is amplified by a ballast inductance connected to the lamp. In the circuit shown in Fig. 1, the starter circuit 8 is connected across A.C. supply terminals 6, 7 and is also connected to three tapping points on the ballast inductance 4. A capacitive voltage divider 9, 11 is also connected across the supply. When the main switch 5 is closed, a further capacitor 16 charges until its potential is sufficient to break down a diac 14b which triggers a triac 14a into conduction. The capacitor 9 now discharges through the section 4a-4b of the inductance 4 which then applies an amplified voltage to the lamp 1 resulting in ignition. The components are chosen so that the triac is gated at a peak of the supply voltage and maximum voltage is available. After ignition, resistors 12, 13 are arranged to maintain the voltage on the capacitor 16 below the value necessary to break down the diac 14b. In a modification, Fig. 2 (not shown), two triacs connected through an isolating transformer are used. Breakdown of the first triac generates a control signal for the second, through which the capacitor 9 then discharges as before.

Patent ES-442435-A1 (ES)
Title: Servo-power-assisted hydraulic brake-actuating arrangement
IPC: B60T13/14
Filed: 1975-11-07
Abstract: The arrangement comprises a brake valve for controlling servo pressure which is proportional to the actuating force at a brake pedal and first and second displacement pistons each actuating a different brake circuit. The second displacement piston is actuated on its rear surface under control of the brake valve by the servo pressure introduced into a chamber behind the second displacement piston. The chamber is defined by the second displacement piston and an ancillary piston in a common housing bore. The ancillary piston has connected to its surface remote from the second displacement piston a tappet which in its end position rests against a housing stop. The first displacement piston is actuated by a balance arm, which is pivotably supported by the first displacement piston and the tappet, and a force transmitting member which is displaced by servo pressure when the servo pressure is present. The force transmitting member, in the event of failure of servo pressure, is actuated by the driver's pedal effort directly to actuate the balance arm and, hence, the first and second displacement pistons.

Title: Vibration transmission mechanism for a phonograph
IPC: G11B3/085
Filed: 1977-06-08
Abstract: A phonograph of the type wherein a plastics-made tone arm having an upstanding stylus mounted thereon is pivoted eccentrically on a turntable or rotor, under which a speaker is mounted concentrically for simultaneous rotation therewith relative to a record immovably supported above the turntable. Also mounted on the turntable is a metal-made vibration transmitter rod which is substantially pivotally supported at one end and which rests, at a point intermediate both ends thereof, on the armature of the speaker partly exposed through an aperture in the turntable. The tone arm has its free end resting on the vibration transmitter rod for sliding movement, during playback, from the other end of the rod toward its point of contact with the speaker armature. In order to preclude unnecessary changes in the volume of sound generated by the speaker during playback, the distance between the stylus and the variable point of contact of the tone arm with the vibration transmitter rod is made to decrease, with the progress of playback, in as exact proportion as feasible to the distance between the mentioned variable point and the fixed point of contact of the rod with the speaker armature.

Patent ES-465677-A1 (ES)
Title: Household refrigerator with air circulation and cooling arrangement
IPC: F25D17/04
Filed: 1978-01-02
Abstract: A refrigerator including two compartments, one of which is maintained at a temperature above freezing for the storage of fresh foods and the other of which is maintained at a temperature below freezing for storage of frozen foods is cooled by air circulated over an evaporator disposed outside the compartments. The evaporator comprises a metal plate having a cooling element mounted thereon in heat exchange relationship. The evaporator is positioned in the cabinet in such a manner that the cooling element is disposed in a first passage and air is circulated over the cooling element and then in proportioned amounts to the aforementioned compartments. To reduce the amount of frost collecting on the cooling element a second passage is provided in the refrigerator cabinet adjacent the opposite side of the plate from that on which the cooling element is mounted. Moist air returning from the fresh food compartment is caused to circulate through this second passage in contact with the aforementioned plate so that a substantial amount of the moisture in this air deposits on the plate as frost before the air reaches the first passage and the cooling element. The plate is spaced from the rear inner wall of the refrigerator to form the second passage between the plate and the inner wall of the refrigerator. The warm air circulating through the second passage, which is disposed adjacent a substantial portion of the rear inner wall of the refrigerator, reduces heat leakage from the exterior of the refrigerator to the interior of the refrigerator.

Title: Moulding stretch-deformable film material
IPC: B29D/
Filed: 1978-06-13
Abstract: The method for forming a film (p) of flexible and deformable material, by drawing, into an open container intended for packaging a food product, consists in moulding the film in a mould cavity in order to form therein a recess having a surface whose area and perimeter (10, 15, 16, 13) are essentially equal to those of the internal surface (10, 11, 12, 13) of the desired container. That part of the mould cavity corresponding to a join between a side wall and the base of the container has a radius of curvature greater than that of this join. In each corner of the cavity, the surface of the cavity has a protrusion (18) extending into the cavity. During moulding, the film is moulded around these protrusions (18) in order to form folds (pleats) having opposed sides. After having withdrawn the moulded film from the cavity, the opposed sides are opened out in order to obtain the desired container. This method enables a moulded container to be obtained from a plastic film having approximately equal wall thicknesses.
