Patent ES-295319-A1 (ES)
Title: Method of and means for forming the bead portions of pneumatic tires
IPC: B29D30/24
Filed: 1964-01-15
Abstract: A method of forming a bead portion of a pneumatic tyre by mounting a band of parallel cord fabric plies on a tyre building drum 6 with an end portion projecting past one end of the drum and overlying an inflatable, radially expansible, elastic air bag 7 positioned at the said drum end, placing a bead ring against the portion of the ply band overlying the drum shoulder and folding the end of the ply band around the bead ring and against the ply band on the end portion of the drum by inflating the bag 7 to extend it radially and by forcing the radially extended portion of the bag axially over the end of the drum, is characterized in that the portion of the expanded bag 7 surrounding the drum is collapsed into gripping engagement with the ply band on the drum by holding that portion of the bag 7 against axially outward movement while deflating the bag. The bead ring is applied to the ply band by means of an annular support member 22 which is slidably attached, by circumferentially spaced, axially extending rods 25, to a backing plate 21 of a bag-engaging sleeve 20, the member 22 being biased towards the backing plate 21 by springs 27. When the sleeve 20 is retracted from the drum 6 the axially outer ends of the rods 25 engage the wall of the housing which supports the drum shaft so that the support 22 is held stationary and aligned with the axially inner end of the sleeve to facilitate the insertion of the bead ring. The sleeve 20 is then moved axially over the uninflated bag 7 towards the drum until the bead ring is pressed against the ply band. The sleeve is retracted and the bag 7 inflated. The annular bag 7, when uninflated, has a cylindrical radially outer wall, while its radially inner wall is radially inwardly contracted at its axially inner and outer ends to form enlargements 93, 94 such that, as the bag is inflated, a strong axially outward pull on the bag causes the ply band to be pulled axially outwards. When fully inflated the bag 7 presses the ply band against the axially outer face of the bead ring, and the sleeve 20 is advanced to force the radially extended portion of the bag together with the ply band around the bead ring and over the drum end. Slippage between the bag wall and the ply band or the interior of the sleeve 20 is prevented by means of circumferential ribs 101 formed on the exterior of the bag wall. Thus the portion of the bag wall which is collapsed over the drum is held against axially outward movement. The bag is released from gripping engagement with the drum by partially inflating the bag. The second bead portion of the tyre is formed simultaneously by an inflatable bag 8 and a second sleeve 20 which is cam-operated into a horizontal position below the drum to permit removal of the tyre. The bead ring support member 22 is fixed to the backing plate since the bead ring can be easily inserted when the sleeve 20 is swung down into its horizontal position.

Title: Method of extracting saponins
IPC: B01D11/00
Filed: 1965-02-16
Abstract: A purified mixture of saponins is obtained from the root of Ranunculus ficaria (the lesser celandine) by boiling the root with water, methanol, ethanol, or aqueous methanol or ethanol, evaporating the filtered extract to dryness, boiling the residue with an aromatic hydrocarbon, and then extracting the insoluble residue with boiling acetone, to leave a residue which is recrystallised from methanol or ethanol. The preferred initial extraction solvent is aqueous ethanol or aqueous methanol, and the aromatic hydrocarbon may be benzene. The root is suitably given a primary treatment with boiling ethanol vapour, dried, and ground before extraction. The inventive product comprises saponins, which are said to have vasoconstrictive and local anti-inflammatory properties, and may be used in pharmaceutical compositions, together with a non-toxic physiologically acceptable carrier, in forms suitable for oral, topical or parenteral application. Topically applicable forms may comprise ointments or suppositories. In an example, an ointment comprises a standardised aqueous solution of the active agent in an ointment base containing stearic esters of ethylene glycol, polyoxyethylene glycol and glycerol, paraffin oil, and preservatives.

Patent ES-352501-A1 (ES)
Title: Matrix storage
IPC: G11C11/06
Filed: 1968-04-06
Abstract: In a matrix memory in which the x, y drive lines cross each other a plurality of times to define a group of storage elements at each set of intersections of the y drive lines with the x drive lines, the y drive lines are divided into two portions each including a switch so that y drive current can be operatively or not operatively linked with a respective group of elements. In the embodiment of Fig. 2 three x drive lines X1, X2, X3 and three column y drive lines Y1, Y2, Y3 cross each other three times to form three matrices 1, 2, 3 as shown, each column line coupling three storage elements e.g. E111, E121, E131 in each matrix which elements form a group. As shown, each y drive line is divided into two parallel portions e.g. Y111 and Y1111 one of which Y111 links the storage elements and the other by-passes them so that drive currents can pass through the portion linking the cores or by-pass the elements. Each portion of the y conductor is connected as shown to primary windings U111, S111 of two transformers U, S. In operation assuming all the elements to be in the " 0 " state and element E132 is to be changed to its " 1 " state current pulses are applied to drive lines x 3 , y 2 . In addition a pulse is applied to terminal P11 of transistor T11 so that the transistor becomes conductive and one of the secondary windings U1111, U1112 is short circuited depending upon the direction of current in the driver line Y2. Since the impedance of the primary winding U112 is determined by the impedance of the load presented to the secondary winding U1111, U1112 current from the drive current source passes through drive line Y112. Transistor T12 of transformer S is not energized so that the primary winding Y112 presents a high impedance to the drive pulse on drive conductor Y2. The coincident currents on drive lines X3, Y2 thus switch the element E132 to its " 1 " state. Similarly elements E232 or E332 in matrices 2, 3 may be switched or not by controlling the conductivities of transistors T21, T22 and T31, T32 so that current flows through drive line portions Y122, Y132 or Y1122, Y1132 respectively. Any change of state of the elements is sensed by sense windings L1, L2, L3. In the arrangement of Fig. 4 the y drive lines are connected in pairs as shown each drive line of a pair having its own switches. The storage elements may be ferrite toroids or ferro-electric material.

Title: Improvements in cyclone separators
IPC: B04B5/12
Filed: 1968-10-15
Abstract: In a cyclone separator for cleaning fibre suspensions the separated light fraction, i.e. the cleaned fibre suspension, is discharged through a central outlet member 3, e.g. having a venturishaped nozzle channel 4, in which partitions 5 are arranged, e.g. radially, to divide the outgoing fraction into a number of parallel flows, the partitions being joined by a central nave part 6 which projects beyond the outer end 8 of the member 3 so as to constitute a distance piece for defining a spacing between the end 8 and a casing 7 in which the outlet member 3 is mounted. This arrangement causes the outgoing fraction to be spread radially outwards without risk of the fibres becoming twisted due to whirl formations. The cyclone may have one or more tangential inlets 2. A number of separators may be arranged with their outlet members mounted in a common casing.

Filed: 1973-02-28
Abstract: A monitor and control system for a ship's electrical power supply of the type having a standby generator. The system includes a variety of threshold detector sensing means responsive to various conditions relating to the operation of the generator. Upon the occurrence of a malfunction, the threshold detectors provide digital signals to an alarm logic circuit which actuates an audible alarm and enables a gating means so as to pass a pulse train to a lighting circuit and thereby provide a flashing visual alarm. The alarm logic circuit also contains acknowledge means operable by a member of the sbip's crew. Operation of the acknowledge means switches a flip-flop so as to silence the audible alarm and maintain the visual alarm in a constantly illuminated condition. Correction of a malfunction returns the corresponding threshold detector to its normal condition, resets the alarm logic circuit and extinguishes the visual alarm. The system further contains an automatic transfer logic circuit which responds to the threshold detectors so as to remove the operating generator from the line when a malfunction occurs, determines if the standby generator is operative, and connects the standby generator across the line when its voltage and frequency have reached acceptable levels.
