Title: Electric contact device used with push-button activation
IPC: H01H13/02
Filed: 1968-06-28
Abstract: A pushbutton switch comprises a fixed contact 9 and a movable contact 7 on the end of bent strip 3 the free end of which is gripped between extensions 8a or arm 8 of intermediate element 1 pivoted at 2 and having a second arm 14 actuated by dog 11 on extension 12 of the pushbutton. Spring 17 urges the free end of strip 3 towards the fixed contact but movement is prevented by dog 11 engaging surface 15 of arm 14. When the pushbutton is depressed, extension 12 and dog 11 move downwards and arm 14 is freed and the contacts are closed. When the pushbutton is released a retractive spring urges it upwards so that dog 11 engages cam surface 16 of arm 14 and cams it back to its original position breaking the contacts. Surfaces 15 and 16 on the end of arm 14 may be arranged, Figs. 4, 7, 8 (not shown), so that the contacts are normally closed and when dog 11 moves downwards it engages cam surface 16 and opens the contacts. There may be two sets of contacts each with its element 1 on each side of centrally disposed extension 12. A number of pushbutton units may be mounted in control panel, Fig. 10 (not shown), each secured by a ratchet spring 22, Fig. 1 (not shown). A signal lamp is provided within the pushbutton.

Patent ES-367255-A1 (ES)
Title: Electric motor propulsion system
IPC: B60M/
Filed: 1969-05-14
Abstract: In a propulsion system for a number of independent vehicles, e.g. trucks of a conveyer, each having an armature 14, Fig. 4, co-operating with the stator 10 of a linear induction motor carrying a polyphase winding, the winding is divided into a number of electrically separate reactors 16, 161, 1611 which are cyclically connected to the supply 24, e.g. by sets of diodes such as 18, 181, 1811 so as to produce a travelling field having zones in each of which the field is of varying strength so as to retain an armature 14 within a zone. In this way, an armature tends to travel in the portion of a zone appropriate to the load in its associated truck. If the truck tends to slow down, the armature enters a portion of the zone of greater field strength and vice versa. Collisions are thus avoided. The varying field may be produced by varying the pole pitch of each winding section or varying the supply frequency or voltage. Fig. 5 shows a waveform produced by varying the supply voltage in which each zone comprises three steps. Alternatively, two steps only may be provided or a sawtooth waveform, Fig. 7 (not shown). Control of the rectifiers in Fig. 4 may be governed by selective switching means and a proximity detector for the armatures so that only the winding sections adjacent the armatures are energized.

Title: Fluid control system for liquid storage apparatus
IPC: F17C13/12
Filed: 1969-10-30
Abstract: L.N.G. is stored under pressure and near its boiling point in a heat-insulated vessel 20a having no ullage space and vapour evolved due to heat leak together with expanded liquid is vented through a duct 34 leading to a drum 38 of sufficient capacity to accommodate said vented vapour and liquid and having sufficient ullage space to provide for expansion and vaporization due to normal heat leak in the drum itself which latter has a pressure relief vent valve 61 in a discharge stack 62. A plurality of vessels 20a to 20n are vertically mounted in a ship's hold and have access ducts 21a to 21n connected by relief valve 36a to 36n to the vent duct 34 and by liquid block valves 27a to 27n to an insulated liquid header 26 having one end leading to the drum 38 and the opposite end connectable to a shore liquidfill and emptying line 11 and a pump 12 to a tank 10. The storage vessels have further access ducts 22a connected by relief valves 35a to 35n to vent duct 34 and by block valves 31a to a main uninsulated vapour header 30 connected at one end to drum 38 and connectable at the other end to a shore line 13 and a compressor 14 to the vapour space of tank 10. Vapour block valves 31a-31n are each controlled by a liquid sensor 32a to 32n whilst the liquid block valves 27a to 27n are controlled by vapour sensors 28a to 28n. The liquid level in drum 38 is maintained below a predetermined height by means 49 which withdraws excess liquid, vaporizes it and discharges either through valve 61 and stack 62 or through a line 55 to the ship's engines or to a burner 59. To fill the vessels 20a-20n and with shore lines 11, 13 connected to headers 26, 30 a valve 48 in header 26 is closed, valves 23a to 23n and open as are valves 15, 16, 29, 33 and pump 12 is operated and liquid flows through open liquid block valves 27a to 27n to the vessels 20a to 20n whilst vapour is forced through open valves 31a to 31n, header 30 and line 13 to tank 10. When a given vessel, say 20a, is filled with liquid, the level reaches a sensor 32a which then closes the liquid block valve 27a, which it controls, and filling is completed when sensor 32n closes valve 27n. During the voyage valves 23a to 23n and 27a to 27n are closed but valve 48 and vapour block valves 31a to 31n remain open whereby expansion liquid in access ducts 22a to 22n gains access to the uninsulated header 30 where it is vaporized and carried through the vent header to the drum 38.

Patent ES-420920-A1 (ES)
Title: Distillation drying process
IPC: C10G33/00
Filed: 1973-11-28
Abstract: A process for drying, or simultaneously fractionationing and partially drying hydrocarbons having a dew point above that of water at the process conditions is performed in a single distillation column having two condensing stages and two receiving vessels on the reflux system, with the first receiving vessel containing no liquid water phase. Condensation in the first stage is purposely incomplete to avoid the formation of a liquid water phase, and to thereby form a reflux liquid that is drier than that in the prior art because it is in equilibrium with water vapor rather than with a liquid water phase. The remaining water and hydrocarbon vapors are removed, condensed and transferred to the second receiving vessel for decantation.
