Patent ES-304965-A1 (ES)
Title: Improvements in and relating to the production of shaped articles from organic thermoplastic materials
IPC: B29C41/04
Filed: 1964-10-15
Abstract: A box, crate, drum or like open-mouthed hollow article is moulded from an organic thermoplastic material by rotational casting in a mould, one surface of which has projections 4 into the mould cavity, the material being introduced into the cavity in such amounts that the walls of the moulding 6 become fused at 7 opposite the projections but are elsewhere separated by cavities. As shown, the mould is in the form of a pair of mould plates 1, 2 secured by clips 3. The articles may be formed in two or more parts which are subsequently joined together, for example by welding. For producing tubular bodies the mould is rotated about its longitudinal axis only, and for other articles the mould is rotated about two or more axes, for example two at right angles. The mould may be treated in an oven, by radiant heat or by electrical heaters in or around the mould walls, and cooled by water or cold air. A solid thermoplastic, e.g. polythene, polyproplene, unplasticized polyvinyl chloride and vinyl chloride/vinyl acetate polymer, may be introduced into the mould, heating the mould before and/or during its rotation. Alternatively a fluid polymer/plasticizer paste, e.g. polyvinyl chloride, is introduced into the mould, rotating the mould at a temperature below the paste setting temperature, and then heating the mould to gel the paste. The solid thermoplastic material is preferably powdered, granular or in other particulate form with a bulk density such as to fill the mould substantially completely. Preferably the bulk density of the material will be not exceeding 0.75 times the specific gravity of the thermoplastic material. In a preferred embodiment polythene with a melt flow index of 20 and specific gravity of 0.924 is cut into granules passing an 8-inch sieve and with a bulk density of 0.40 grams per c.c. fills a mould having a space between the plates of 0.25 and 0.5 inch. The mould is closed and then rotated about its longitudinal and transverse axes and while rotated it is heated for 10 minutes in an oven at 205 C. and then cooled in water. The finished panel had walls of 0.15 inch wide between ribs which were 0À6 inch wide at the wall joints.

Prefered arrangements have two orifices in each group, the orifices having either a Y or an X- shape, and being disposed opposite one another as mirror images. In each case the length of each arm is at least twice its width, and the distance apart of the closest point of the two orifices is at least as great as the arm leading to those points. The angles between the slot arms may be equal or unequal.

Patent ES-350072-A1 (ES)
Title: Pulse generator
IPC: H03K3/30
Filed: 1968-02-02
Abstract: In a pulse generator a capacitor 18 is periodically discharged substantially linearly by a voltage A of opposite polarity and each time the voltage across the capacitor reaches a given value an amplifier element 4 conducts and the capacitor 18 is again charged, a rectifier element 19 which is conductive for the charging but is cut off by synchronization pulses is connected between the capacitor 18 and the control electrode of the amplifier element 4. The pulse generator produces an output at 12 for the vertical or frame deflection coils of a colour television receiver. A positive pulse from winding 15 is applied via differentiating circuit 16, 17 to the base of a transistor 4 and at the beginning of the fly-back period causes the transistor 4 to conduct to discharge a capacitor 3. The base of transistor 4 becomes negative due to the charge across capacitor 17 and at the end of the fly-back and start of the stroke the voltage feed-back via the differentiating circuit 16, 17 makes the base further negative and transistor 4 turns off. The diode 19 turns on and the capacitor 18 which stabilizes the frequency together with capacitor 17 discharge and charge reversely to the voltage at A. The positive voltage now at the base of the transistor 4 causes it to conduct and the above is repeated. Synchronizing pulses are applied at 26 to cut off the diode 19. The natural frequency of the circuit remains substantially constant since the charging and discharging voltages of the capacitors are proportional to the supply voltage. The conduction of the output valve 7 is dependent on the state of charge on the capacitor 3 and is also determined by the feedback network 13. The resistor 20 may be variable as may be resistor 1.
Patent ES-351833-A1 (ES)
Title: Method and apparatus for eliminating waste heat and reaction water together from fuel cells
IPC: H01M8/06
Filed: 1968-03-21
Abstract: Electrolyte from a fuel cell (not shown) flowing in a chamber 1 releases water, by diffusing through membrane 2 in vapour form only, into a chamber bounded by a cooled surface 3 onto which water condenses. The cooling of surface 3 may be controlled by a temperature sensing member in the electrolyte. Re- -action water is released permanently from the system via valve 5 and a known pressure lock 7-10 valve 5 may be controlled by a device for measuring electrolyte level or concentration. Cooled water may, as shown, be forced directly through membrane 2 back into the chamber 1 by maintaining a superatmospheric pressure in chamber 4, or it may be returned via a threeway cock (15) in series with a pressure look (16) (Fig. 2, not shown), or the condensation surface (32) may itself be porous, so that the condensed water flows through it to join a cooling water water stream (35), part of which may be returned to the electrolyte via a pressure lock (29), Fig. 3 (not shown). The porous membrane may consitute an electrode of the cell.

Title: Device for cargo trucks for transporting and lateral loading and unloading
IPC: B60P1/64
Filed: 1968-05-24
Abstract: A truck 11 has loading/unloading devices 2, 3 at the rear and front respectively of the truck. Each device comprises an arm 16 pivoted to a support 15 which is itself pivotally mounted at 18 on a truck member 19. A piston-cylinder unit 20 controls the pivotal movement of the support 15 and a piston-cylinder unit actuates the arm 16. From this arm is suspended a loadgripping device 1, consisting of a pair of gripping plates 5, 6 pivoted to a centre member 4 and actuated by a piston-cylinder unit 10. The plates 5 and 6 have gripping members 25. In using the device 2 (or 3) a first stack of stones is loaded and deposited at a position 12 on the truck. A second stack of stones 14 is then lifted and lowered beside the stack 12 but the plates 5, 6 remain adjacent the stack 14, Fig. 2. The arm 16 is then lowered, a side 13 of the truck is raised and the truck is ready to move. Stabilizing supports 28, 29 are provided. Only one plate 5 of the plates 5, 6 needs to be pivotable.
Patent ES-356709-A1 (ES)
Title: Continuous process for simultaneously producing coke and carbon black
IPC: C09C1/50
Filed: 1968-07-31
Abstract: Coke and carbon black are produced simultaneously by continuously feeding a flat coal bed through a carbonizer for partial combustion with air to produce partial coking, reaction of the air with part of the hydrocarbons, and cracking of unreacted hydrocarbons, to form carbon black which is carried by the combustion gases via 64 to a filter 68 where it is recovered. Coking is completed in a shaft furnace. The pressure in the carbonizer must be controlled by a damper 70 so that it never falls below 0 inches of water, thus preventing the ingress of air and burning of carbon black. A pressure of 0À05 to 0À1 inch of water may be maintained. Air for combustion is preheated at 36 by gases from 32, 34 which pass to the cooler 28 via 38, 42. The heated air is delivered to separate zones in the carbonizer (see Fig. 2, not shown).

Title: Method of preparing a food batter starch
IPC: C08B31/18
Filed: 1968-10-26
Abstract: An aqueous slurry of raw granular starch is treated with a mixture of a hypohalogenous acid and a halogen, followed by treatment with different less powerful, oxidizing agent. The pH during treatment may be pH 1-6, and the final product adjusted to pH 5-7, preferably by use of an alkaline potassium compound, followed by adjustment to 15-30% solids, filtration and drying to a moisture content of less than 14% by weight. The use of hypochlorous acid with chlorine, followed by treatment with H 2 O 2 is exemplified. The acid and halogen may be derived from (i) an alkali metal hypohalite, (ii) electrolysis of an acidic halide-containing starch slurry or (iii) by addition of halogen to an acidic starch slurry. Many starches, including high amylose and starch-containing cereal flours may be so treated. The product is useful as a batter mix for foodstuffs, and exhibits increased adhesion thereto.
