Patent ES-339398-A1 (ES)
Title: Hydrocarbon process
IPC: C07C67/00
Filed: 1967-04-17
Abstract: Olefins, particularly ethylene, are produced by thermal cracking of a hydrocarbon feed by indirect heating in a tubular reaction zone under the following conditions: steam: hydrocarbon weight ratio: 0À1-2À0 residence time: 0À1-0À5 seconds gas effluent outlet temperature: at least 1500 F. outlet gas hydrocarbon partial pressure: 5-20 p.s.i.a. pressure drop across reaction zone: at most 30 p.s.i. and rapidly cooling the effluent gases to a temperature at which cracking ceases. The process may use a furnace comprising a convection preheat zone and a radiant cracking zone, the tubes in the cracking zone being relatively short, of small diameter and of low pressure drop design. The tubes may be connected to form a coil, and the furnace may comprise more than one coil assembly. The rapid cooling may be carried out in the apparatus of Specification 1,165,908, comprising three concentric pipes which form a central chamber and two annular chambers. Cooling fluid, e.g. water, enters the top of the central chamber, which communicates at its bottom with the first annular chamber. The hot effluent passes through the second annular chamber, the inner wall of which forms a cooling surface. The outer wall of the second chamber may also be used as a cooling surface by welding cooling pipes to the exterior of the outermost concentric pipe. The cooler may operate in conjunction with a steam generator, and can be made self-regulating by a thermo-siphon effect. The hydrocarbon feed may range from ethane to crude oil, the examples using naphtha.

Title: Nuclear Power Plant
IPC: G21D5/08
Filed: 1968-03-06
Abstract: In a fast breeder nuclear reactor power plant, a gas-turbine is driven by CO 2 gas heated in a heat exchanger in the primary circuit of which flows the reactor liquid sodium coolant. The turbine exhaust is compressed before return to the heat exchanger and a regenerative heat exchanger transfers heat from the turbine exhaust to the compressed CO 2 . Carbon monoxide or graphite may be added to the CO 2 to reduce corrosion or improve heat transfer. In a modification a two-stage gas turbine is employed with interstage heating.

Title: Hydraulic damper with one-way valved by-pass in cylinder head
IPC: F16F9/36
Filed: 1968-10-17
Abstract: A tube-within-a-tube hydropneumatic shock absorber, of the kind in which the gas is situated above liquid in the outer tube, is characterized by the nature of the means which allowliquidleakage from the inner tube past the piston-rod to the outer tube whilst preventing gas from the outer tube entering the inner tube. This means includes a valve element, as shown a simple 0-ring 19, which is located in a recess 16 within the sealing means 12, 13 of the two tubes. This recess is required to be radially spaced from the piston-rod 8 so that the valve element does not engage the moving rod. The flow path from the inner to the outer tube is by way of the annular space 20 between the piston-rod and the sealing member 12, the passages 17 and the passage 18.
Patent ES-359265-A1 (ES)
Title: Image amplification in ionography by avalanche method
IPC: G03G15/054
Filed: 1968-10-17
Abstract: In an ionographic imaging apparatus in which a stream of charged particles falls on to the surface of an insulator according to imaging radiation, the retarding electric field created by deposited charge is neutralized by simultaneously produced adjacent charges. In one embodiment the pattern of X-rays from a source 14 transmitted by an object 12 passes through a cathode 16, having a photoemissive layer 18, from which electrons are ejected towards an anode 20 in contact with a photoconductive layer 28 coated with an insulating layer 30. With a quenching gas between the electrodes avalanching occurs and the amplified electron image falls on to the insulator 30 previously charged to a positive potential. The positive surface charge is neutralized imagewise as the induced negative charge between layers 28 and 30 is conducted to electrode 20 imagewise through layer 28 thus reducing the retarding field of the deposited charge. In a second embodment Fig. 2, (not shown) the photoconductive layer 28 is omitted and a photo-emissive layer is coated on the opposite side of the anode from the insulative layer. Deposition of negative charge on the insulative layer (58) is compensated by simultaneous emission of electrons from the layer (60). In this case two electrostatic images are formed. The layer (60) may be formed of a low work function material in which case the electrons liberated by X-rays are collected by the electrode in contact with the layer, Figs.3 and 4, (not shown).

Title: Water treating device
IPC: C02F1/76
Filed: 1969-10-16
Abstract: In apparatus for diluting bromine (or other antiseptic) and adding it to water flowing in a conduit 21, water is withdrawn at 4 from the main flow by a pump 5 and supplied to constant level tanks 7, 12 and to mixing vessel 2 which comprises a jet pump. The tank 7 supplies water at a rate controlled by a valve 3 to a bromine storage vessel 1, forming brominated water which passes through conduit 10 under pressure from the tank 7 assisted by the induction of the jet pump. The induction side of the jet pump is also connected by conduit 11 to tank 12 the water level in which regulates the reduction in pressure communicated to vessel 1. The highly diluted bromine solution from the mixing vessel 2 passes through conduit 14 and surge tank 15 back to the main flow. The valve 3 may be operated manually to vary the frequency and/ or period of operation, or by an electromechanical or electronic system in response to continuous measurement of the bromine content of the water to be treated.

Patent ES-405034-A1 (ES)
Title: Electronic latch circuit
IPC: H03K5/05
Filed: 1972-07-21
Abstract: An AND gate has a signal input to which a periodic signal is applied and a control input to which a control pulse is momentarily applied. In response to the concurrent presence of the periodic signal and the control pulse at the respective inputs, a periodic signal is provided at the output of the AND gate. The periodic signal provided at the output of the AND gate is detected for charging a charge storage means to a voltage level of substantially the same level as the voltage level of the control pulse. This latter voltage level is fed back to the control input of the gate, and in response thereto, the gate continues to provide the periodic signal at its output after the control pulse terminates and until the periodic input signal to the gate is interrupted. The periodic output signal from the gate is amplified in an amplifier and provided as the output signal of the latch circuit. In response to the sensing of the AND gate no longer providing the periodic output signal, the charge storage means then rapidly discharges through the amplifier.

Title: Control rod for a nuclear reactor
IPC: G21C7/14
Filed: 1975-02-18
Abstract: A control rod assembly for a nuclear reactor is disclosed having a remotely disengageable coupling between the control rod and the control rod drive shaft. The coupling is actuated by first lowering then raising the drive shaft. The described motion causes axial repositioning of a pin in a grooved rotatable cylinder, each being attached to different parts of the drive shaft which are axially movable relative to each other. In one embodiment, the relative axial motion of the parts of the drive shaft is used either to couple or to uncouple the connection by forcing resilient members attached to the drive shaft into or out of shouldered engagement, respectively, with an indentation formed in the control rod.
Patent ES-437357-A1 (ES)
Title: Method for making structural foam profiles
IPC: B29C48/355
Filed: 1975-04-30
Abstract: The technique uses an extruder for delivering a supply of softened thermoplastic resin material containing a foaming or expanding agent, the resin material being under pressure and therefore unexpanded in the extruder, but being delivered into a unconfined zone of lower pressure for partial expansion. The partially expanded resin material is drawn by a puller mechanism through a chilled shaping or sizing die of a cross sectional dimension smaller than that of the material in the unconfined zone. The material drawn into the sizing die continues its expansion in the interior of the profile with resultant development of porosity in the core of the profile while the surface layer is cooled and hardens as a substantially unexpanded structural shell.
