Patent ES-340033-A1 (ES)
Title: Reverse osmosis membrane and method of manufacture
IPC: B32B23/20
Filed: 1967-04-29
Abstract: Cellulose acetate membranes used as desalination membranes have an acetyl content of 41À5% to 42À7% based on the weight of the cellulose. The critical acetyl range of the cellulose acetate used may be obtained by blending commercially available cellulose acetate compositions to attain the desired acetyl content, or the cellulose acetate solution may be initially prepared to have such an acetyl content.

Title: Improvements in or relating to the production of polyurethane foam
IPC: B29C44/28
Filed: 1969-12-31
Abstract: Polymeric foam is continuously cast on a conveyer and the sides of the foam are restrained by a lining which moves and rises with the foam so that the top surface of the foam, after setting, is substantially flat.

Patent ES-387824-A1 (ES)
Title: Device for replacing used gloves in a glove box
IPC: G21F7/053
Filed: 1971-01-30
Abstract: A device for replacing a used outer glove 7 by a new glove 10 in a double-walled glove box having an inner wall 1 and outer wall 2, the wall 1 having a glove ring 3 of smaller diameter than the ring 4 of wall 2, comprises a tubular body 8 which is placed in position within the ring 4 after removal of an inner glove (not shown) located in a groove 5 on the ring 4, this glove extending into the interior of the glove 7. Prior to positioning the device the new glove 10 is attached thereto as shown by turning the gauntlet inside out and placing the glove bead 14 in a groove 13 formed in a skirt 12 of the body 8. When it is required to change the glove 7 it is moved manually from the groove 5 to the groove 6 of the ring 3 and the inner glove is then removed from the ring 4. The device is then placed in position. This device comprises a sleeve 16 having a chamfered end surface 16a is slidably mounted on the body 8 but is prevented from rotation thereon by slots 20 cooperating with stops 18 on the body. Rotation of the assembly 8, 16 relatively to the rings 3, 4 is prevented by a collar 24 having arms 22 extending through the slots 20, screws 28 in the arms being clamped against the groove 6 of ring 4. Springs 26 acting between the collar 24 and the body 8 bias the latter so that the end surface 12a of the skirt 12 causes the glove 10 to abut the inner wall 1 and effect a seal therewith. Thus the used glove 7 may now be detached and drawn into the glove box without leakage of the glove box atmosphere. A ring 30 is rotatably mounted on the body 8 between guides 32 and operating arms 34 on the ring extend through a helical slot 36 in the sleeve 16. These arms 34 are moved along the slot so that the sleeve 16 moves axially towards the wall 1 causing the glove bead 14 to leave the groove 13 and abut the wall, further movement of the arms causing the assembly 8, 16 to move away from the wall against the action of springs 26 and the bead 14 slides on to the ring 3. A slight pull on the glove 10 brings the bead 14 into groove 5. The screws 28 are now loosened and the device removed and the inner glove is replaced in the ring 4.

Title: Electronic control device for intermittent operation of a windscreen wiper, particularly for motor vehicles
IPC: B60S1/08
Filed: 1971-11-04
Abstract: An adjustable electronic timing device for controlling the operating speed of windscreen wipers. A switch is provided for operating the wipers in either a continuous or an intermittent fashion.

Title: Phase difference measuring device
IPC: G01R25/00
Filed: 1972-03-11
Abstract: Device for measuring the phase difference between two alternating-voltage signals. These alternating-voltage signals are transformed into sawtooth voltages having equal peak-to-peak values. In an adder there is added to the difference between these sawtooth voltages a voltage which is derived from a direct-voltage supply source via a switching member which is switched at instants which correspond to the steep edges of the two sawtooth voltages, the arrangement being such that the adder delivers a direct voltage proportional to the phase difference between the two sawtooth voltages. The invention is of particular importance for a device for generating two triangular voltages having an adjustable phase difference.

Title: Benzomorphanes derivatives
IPC: A61K31/435
Filed: 1975-08-20
Abstract: Novel 2-tetrahydrofurfuryl-6-7-benzomorphans of the accompanying formula I, in which R<1> denotes methyl, ethyl or propyl R<2> denotes hydrogen, methyl or ethyl R<3> denotes hydrogen or methyl and R<4> denotes hydrogen, alkyl having 1 to 4 carbon atoms or acyl having 2 to 5 carbon atoms, are prepared by introducing the tetrahydrofurfuryl radical into appropriately substituted norbenzomorphans by the methods of N-alkylation. The resulting bases of the formula I can then be converted into their acid addition salts. The compounds of the formula I and their acid addition salts are distinguished by a therapeutically utilisable action on the central nervous system. Particularly to be emphasised is their analgesic action, which frequently exceeds that of morphine, without exhibiting the undesired side effects of morphine, e.g. the addictive action.

Title: Method for processing coke oven gas
IPC: C01B3/22
Filed: 1978-07-20
Abstract: Hot coke oven gas is subjected, immediately after the discharge thereof from coke ovens, and without any preliminary cooling operation, to partial oxidation and cracking with an oxygen-containing gas, thereby forming a hot cracked gas rich in carbon monoxide and hydrogen.
