Patent ES-356650-A1 (ES)
Title: Improvements in or relating to the Removal of Residual Gas from Gas Tanks
IPC: B63B57/04
Filed: 1968-07-30
Abstract: Removal of residual gas e.g., ammonia from a storage tank 1 is effected by introducing a carrier gas e.g., propane into the tank withdrawing the gaseous mixture so formed by means of a compressor 9 into a scrubber tower 3 where the mixture is contacted with a liquid e.g., water which dissolves the ammonia but not the propane and returning the ammonia-free propane by means of the compressor 9 to the tank 1. In operation the water is supplied by a pump 4, water particles entrained by the ammonia-free propane are separated at 8 after which the propane is heated at 10 prior to compression and the compressed propane is then freed of water vapour by passage through a water cooled condenser 12 or through chemical driers 16 and passed through a line 11 and expansion valve 14 into the tank 1. After complete removal of residual ammonia the tank is charged with propane for storage.

Title: Heating inserts
IPC: A47L15/42
Filed: 1968-12-21
Abstract: In an electric immersion heater comprising a heating element 2 whose cold ends 1 pass in sealing relationship through an elastomeric sealing element 3 mounted in an opening in a tank wall 6, the element 3 has a flange 5 resting on one side of the tank wall 6 and at least one blind aperture 4 which is open on the said one side of the tank wall and whose bottom is located on the other side of the tank wall, the aperture or apertures 4 accommodating a fixing element 7 which presses the side walls of the sealing element 3 into sealing relationship with the opening in the tank wall. The fixing element comprises two angled plates 8 joined by a deformable strip 12. The plates 8 have lugs not shown which co-operate with the ends 1 of the heating element 2 to force them into engagement with the rounded ends of aperture 4 and deform elements 3 when the fixing element is secured in position. The fixing element 7 is placed in aperture 4 and plates 8 are pivoted towards one another about edges 9 to form a bead 15 on the sealing element 3 which seals the rim of the tank opening. At the same time strip 12 is permanently deformed. An earth terminal 13 is provided on the fixing element 7 which makes good electrical contact with the metal sheathed heating element 2. The fixing element 7 and sealing member 3 may be inverted so that they are accessible from within the tank (Fig. 3, not shown). In Fig. 7 (not shown) the plates 8 are pivoted to cause sealing element 3 to make a fluid-tight seal with the edges of the tank opening by screwing a bolt, which passes through a clip with wedge-like surfaces, into a nut held captive between the plates 8. The heater may be used in dish washers, washing machines or hot-water dispensers. A temperature sensitive device (e.g. a thermocouple) may pass through the sealing element.

Patent ES-392760-A1 (ES)
Title: Mechanism for radial adjustment of tools in rotary tubular tool holders of shaving machines or the like
IPC: B23B29/00
Filed: 1971-06-30
Abstract: A shaving machine for tubular or rod-like workpieces has a tubular tool holder which is rotatable in two axially spaced main antifriction bearings installed in the machine frame. An auxiliary antifriction bearing surrounds the tool holder between the two main bearings and its inner race is coupled by rods with a sleeve which is movable axially of the tool holder in the region of one main bearing. The sleeve has a conical internal surface abutting against complementary conical surfaces of several equidistant supports for shaving tools which are caused to move radially in response to axial movement of the sleeve. The outer race of the auxiliary bearing carries several nuts which mesh with axially parallel feed screws mounted in the machine frame and coupled to each other for simultaneous angular movement by means of pinions provided on the feed screws and meshing with an internal gear which is rotatable in the frame. A reversible electric motor can be drivingly connected with a gear on one of the feed screws by way of either one of two gear trains which can rotate the one feed screw at different speeds. As the one feed screw rotates in the frame, it causes the other feed screws to rotate to the same extent and in the same direction to thereby move the outer race of the auxiliary bearing axially of the tool holder. The outer race shifts the inner race which changes the axial position of the supports for shaving tools so that the tools move radially outwardly or inwardly.

Patent ES-468144-A1 (ES)
Title: Textile machine having hydraulically controlled drafting rollers
IPC: D01H5/52
Filed: 1978-03-22
Abstract: Pressure between rollers in each set thereof in a drawing frame is maintained by oil pressure in a main pipe circuit connected to piston and cylinder assemblies allocated to the sets of rollers. A motor driven pump feeds oil from a tank through a feed pipe to the main circuit except when a first solenoid-controlled valve directs the oil through a first return-flow pipe branched from the feed pipe. So long as a pressure gauge connected to the main circuit is indicating the pressure to be below a minimum, it excites the first solenoid-controlled valve to close the first return-flow pipe. When, as a result of lapping on a drafting roller the gauge indicates a maximum pressure, it causes the machine to stop. A second solenoid-controlled valve has its excitation periodically suppressed to open a passage through a second return-flow pipe to prevent the temperature of the drawing frame from overheating the main pipe circuit.

Patent ES-483409-A1 (ES)
Title: Method of making a ribbon cable
IPC: H01B13/00
Filed: 1979-08-14
Abstract: In multi-core electric cable in which the cores extend in side-by-side spaced and parallel relationship, instead of producing the cable with the cores continuously interconnected by surrounding insulation so that when cut into lengths the insulation has to be pulled or cut apart in order to separate the cores for connecting, the cable is made at the outset at intervals along its length with the cores separate, never having been interconnected. This is applicable to most known methods of manufacturing flat multi-core electric cable including those in which each core has an individual insulating sheath interconnected to form the multi-core cable by the bonding of the sheaths together or to backing strip material or to both. In application to multi-core cables made from bare conductors sandwiched between strips of insulating material separation of the cores at intervals is achieved either by omitting at intervals the bonding of the insulating material or by omitting the insulating material at intervals or by a combination of both.
