Patent ES-454401-A1 (ES)
Title: Headlamp cleaning assembly
IPC: B60S1/48
Filed: 1976-12-18
Abstract: A headlamp cleaning assembly of the type for cleaning vehicle headlamps and including first and second nozzles for jetting an air/liquid mixture against a headlight surface. A regulator means is included for mixing air and liquid and for sequentially supplying the resultant air/liquid mixture to the first nozzle for a first period of time and then to the second nozzle for a second period of time to complete one cycle. The regulator includes a piston slidably disposed in a cavity to define an air/liquid mixing chamber which is opposed by a liquid charging chamber. The piston also defines an air actuation chamber which, when supplied air, moves the piston from a start position to a charged position to charge by filling the charging chamber with liquid. A stem is connected to and extends upwardly from the piston and is slidably disposed in a stem chamber for actuating an air valve which, in turn, allows pressurized air to flow into the stem chamber. A selector valve is in fluid communication with the stem chamber for selectively controlling the flow of the air/liquid mixture between the first and second nozzles. A porting valve is in fluid communication with the stem chamber through an accumulator chamber and is responsive to air pressure in the stem chamber for moving to an open position to allow air pressure to flow to the mixing chamber to drive the piston against the liquid charged chamber so that liquid will flow through a check valve and a timing and atomizing nozzle into the mixing chamber. Also included is a manually actuated control valve which is actuatable to allow air pressure to flow to the air actuating chamber to initiate a cycle.

Title: Process for the manufacture of propylene oxide
IPC: C07C11/09
Filed: 1977-04-12
Abstract: In the epoxidation of propylene with tertiary butyl hydroperoxide to form propylene oxide, a by-product, tertiary butyl alcohol is formed. This alcohol can be dehydrated to form isobutylene which can be sold as a product or hydrogenated, followed by oxidation, and the resulting hydroperoxide reacted with propylene to produce propylene oxide and tertiary butyl alcohol for recycle. In this process, the operation of the tertiary butyl alcohol vaporizer is substantially improved by increasing the quantity of liquid purge to at least 15 weight percent of the input. Under such operating conditions, the organic content of the waste water effluent from the entire plant is reduced, fouling of the vaporizer heat transfer surfaces is minimized thereby increasing the on-stream time between cleanings by as much as 2-3 times the normal, and deposits are more easily removed from the vaporizer when it is shut down for cleaning.

Title: Dry release transfers
IPC: B44C1/17
Filed: 1978-07-20
Abstract: A dry release transfer is disclosed in which the design layer is formed by printing one or more inks onto a carrier sheet, at least one of the inks being a photopolymerizable composition, and subjecting the design layer to ultra-violet radiation or an electron beam discharge in order to polymerize the photopolymerizable ink.

Patent ES-479383-A1 (ES)
Title: Device for protecting pressure vessel of nuclear reactor from rupture
IPC: F16B31/02
Filed: 1979-04-06
Abstract: The pressure vessel closure head (3) is clamped in a sealing fashion with its closure head flange (3.1) by means of prestressed expansion bolts (4) having nuts (4.2) and washers (U1) against the counter-flange (2.1) of a pressure vessel opening. In this arrangement, the washers (U1) are constructed as deformation members and are dimensioned to match the expansion bolts (4) in such a way that upon overshooting of a limiting internal pressure they give way to the closure head forces, under plastic deformation, by the distance DELTA lü in the pressing-on direction. The reduction in the overpressure takes place via the closure head sealing gap (5) which gapes correspondingly by an axial gap of DELTA lü, as far as a value at which the prestressing force of the bolts (4) remaining in the elastic range is sufficient to reseal the pressure vessel (1).

The ram cylinders have inlets 24, 26 connected to a source 34 of the material under low positive pressure with a ball check valve 36, 38 located between the source and each inlet. Outlets 44, 46 of these cylinders are connected to a common outlet 62 with a ball check valve 54, 56 also located between the common outlet and each cylinder outlet. The valves are arranged so that the inlet check valves and the outlet check valves operate in opposing relationship to provide positive opening and closing action and a precise flow of material. An adjustable back-pressure valve 62 places back pressure on the material at the outlet with the pressure exceeding the pressure of the material at the source. Two materials, e.g. resins, may be pumped in a predetermined ratio to a mixing head.

Title: Apparatus for making and stacking plastics bags
IPC: B31B50/98
Filed: 1979-07-27
Abstract: In a bag-making machine, a flattened tubular plastics web is intermittently fed by rollers and the leading end is held taut by air jets from tubes above and below the web. Welding jaws apply base seams for bag sections successively severed from the leading web end by knives. Between the knives and a stacking conveyor for the bag sections there is a supporting plate for the bag sections co-operating with a depressor. Two rows of needles pass alternately through slots in the supporting plate into a raised spiking position. Upon completion of a stack, the needles of one row are moved by a carrier to push the stack closer to the conveyor while the latter is moving and are eventually retracted from the stack while the needles of the other row take their place by moving into the spiking position for the next stack of bag sections.

Title: Electrical connector for flat cable.
IPC: H01R4/24
Filed: 1980-01-14
Abstract: An electrical connector for use in establishing electrical connections to the conductors of a flat cable comprises a first housing member carrying a plurality of terminals each having arms having opposed edges defining a conductor-receiving slot and having pointed extremities for piercing the insulating material of the cable, and a second housing member having a plurality of holes to receive the arms of a respective one of the terminals. The arms of the conductor-receiving portion of each terminal are formed adjacent their free ends with outwardly directed projections which are an interference fit in the associated hole in the second housing member, each arm of each terminal in use engaging the second housing member not only at the projection on the arm but also at a second position adjacent the engagement between the arm and a conductor of the cable received in the slot partially defined by the arm. The second position of engagement between each arm of each terminal and the second housing member serves to relieve the stresses induced in the arms by the engagement between the projections on the arms and the second housing member, this enhancing the contact between the arms and the conductors and ensuring reliable electrical connections.

Patent ES-8100630-A1 (ES)
Title: Method and apparatus for introducing a cable into a vulcanization chamber
IPC: B29C48/06
Filed: 1980-02-26
Abstract: The cable is introduced into a sealing tube containing elastic sealing elements before entering the vulcanization chamber which is separated from the extruder. The elements have closed chambers which can be individually pressurized by, in each case, one line, while pressure regulation takes place by means of pressure reducing valves. Gaps can be provided between the individual chambers and they are filled by the heat transfer medium which brings about the crosslinking of the layer extruded onto cable and which passes out of the intake opening of vulcanization chamber. A leakage flow forms along the entire sealing tube and this passes through the openings of sealing elements and completely fills the annular clearance between the boundary of the opening and the cable, so that any contact between the cable and the sealing elements is at least substantially prevented. The gaps can be filled with a sealing liquid, which then forms the leakage flow instead of or together with the heat transfer medium.
