Patent ES-219776-A1 (ES)
Title: Improvements in and relating to the production of film
IPC: B29C48/10
Filed: 1955-01-27
Abstract: Tubular film of a synthetic organic thermoplastic material is extruded through the peripheral orifice of an annular extrusion channel formed between the plane horizontal surface of an annular die and an opposed parallel die plate, which plate has no projections beyond the plane of its extrusion surface. The die plate is preferably detachably mounted on a core positioned within the annular die. As shown, the peripheral orifice 7 is defined by the horizontal end surface 2 of the annular die 1, and the horizontal surface 5 of die plate 4 which is secured to the core 3 with the interposition of a resilient ring 12. Material to be extruded is fed through the connection 13 into the annular space between the die 1 and core 3. The construction facilitates maintenance of a specified gap round the whole of the peripheral orifice, particularly after re-grinding or re-polishing the extrusion surfaces, since the surfaces concerned are plane. Any slight variations in the gap may be compensated by providing a slightly flexible lip 21 round the die 1, whose position may be varied by adjusting a series of bolts 22 extending round the periphery. Inflating air may be introduced through the axial bore 14. The tubular film is preferably cooled by flowing a cooling liquid over its exterior as it passes downwardly through a suitable passageway. Examples describe the production of tubular film from polyethylene terephthalate and polythene. Specification 741,963 is referred to.

Title: Fuel control for combustion engine
IPC: F02K3/00
Filed: 1963-10-16
Abstract: Fuel supplied to the burners 38 of a gas turbine engine is controlled during acceleration, deceleration and steady running by apparatus comprising an engine driven pump 40, manually adjustable throttle 48 and a passage 46 from which opens a bypass 70 controlled by a valve 72. The pressure difference across the throttle 48, which is proportional to the square of the engine speed, acts on a spring-loaded diaphragm 56 actuating a valve 106 which controls the pressure difference across an orificed diaphragm 78 actuating the bypass valve 72 in opposition to a spring loading determined by a diaphragm 88 responsive to the difference between compressor discharge and atmospheric pressures. Interposed between the passage 46 and the burners 38 are a valve 50, which provides a fixed restriction but can be moved by the throttle control to a shut-off position, and a tapered valve 124 actuated by atmospheric pressure and/or temperature responsive means 130. Spring-loaded ball valves 66, 118 limit the pressure differences across the diaphragms 56, 78. In a modification the speed responsive assembly 40, 48, 56, 106 is replaced by a mechanical governor operating a lever-mounted valve in opposition to a manually adjustable spring.

Title: Apparatus for withdrawing successive samples of a circulating liquid having a constant flow rate in piping
IPC: G01N1/20
Filed: 1964-08-01
Abstract: A device for taking successive samples of a liquid circulating at a constant flow rate comprises an accumulator chamber 1 connected by a pipe 4 to a measuring chamber 2 which communicates, via a pipe 7, with a mixing chamber 3, and a siphon pipe 13 connected to the mixing and accumulator chambers and with atmosphere via a pipe 14 and valve 15, the mixing chamber being connected via a pipe 8, restriction 9, two-way valve 10 and a pipe 11 with a source of vacuum 12 or with atmosphere the measuring chamber 2 is connected with atmosphere via a pipe 5 and valve 6. In operation, both valves 6 and 15 are closed and the valve 10 operated to connect the system to the vacuum source 12 thereby raising liquid into the measuring chamber and part-way up the pipe 7 the valves 6, 10, 15 are then opened to atmosphere as shown thereby allowing excess liquid in the measuring chamber to flow back to the accumulator 1, the measured quantity left in chamber 2 being determined by the entry position of the pipe 4 into the latter chamber. Valve 15 is then closed and the valve 10 operated to connect the pipes 7, 8 with the vacuum source thereby raising the liquid in the measuring chamber into the mixing chamber 3 the above procedure may be repeated several times in order to fill the chamber 3 with a number of measured quantities. A sample of the liquid in the chamber 3 is then removed from the chamber 3 by means e.g. of a sample withdrawing needle. In order to return the liquid in the chamber 3 back into the accumulator chamber 1, the valves 6, 10 and 15 are actuated in such a way as to produce a pressure differential between the interiors of pipes 8 and 14 thereby causing the liquid to be siphoned, via the pipe 13, back into the chamber 1. The liquid in the chamber 3 may be agitated by compressed air of mechanical means and the valves 6, 10, 15 actuated by a programmed control device.
Patent ES-319904-A1 (ES)
Title: Cap crimping tool
IPC: B67B3/14
Filed: 1965-11-23
Abstract: A tool for crimping a cap 2 on a bottle 1 has a pusher 300 and a number of resilient blades 220 which crimp the cap to the bottle as it moves upwards, its neck engaging the pusher 300 and moving it so that a spring 230 between the pusher head 310 and a support ring 210 of the resilient blades is compressed. The cap 2 on the bottle 1 is engaged by a ring spring 222, which may be of helical form. As the bottle neck advances further upwards, it forces projections 221 on the resilient blades 220 to press against a frusto-conical lip 131 on the end of a fixed sleeve 100. This causes the ring 210 to be pulled downwards as the blades 220 are forced further apart. The upward movement of the bottle 1 causes the spring 222 to contact a lip 24 on the cap 2. A stop 322 on the pusher 300 then engages the support ring 210 of the resilient blades and causes the blades 220 to move up with it. The projections 221 slide inside the frusto-conical lip 131 and press the lip 24 of the cap under the rim of the bottle 1. The bottle 1 is moved downwards and pulls the resilient blades with it, until they reach the edge of the lip 131, Fig. 4 (not shown). The bottle 1 can now be disengaged from the tool, which returns to its original position. In a modification, Fig. 5 (not shown), a frusto-conical lip (130) on a fixed housing, is engaged by slidable projections (221) arranged mid-way along instead of at the end of the resilient blades (220). A device for receiving and positioning the caps before the bottle is introduced to the tool is provided. It comprises three fingers (142) which are urged by springs (144) towards the axis of the tool. Alternatively, the caps 2 may be held in position by other means, e.g. magnetic means. Instead of the bottle 1 moving up with the tool, the tool may move downwards on to the bottle.
