Patent ES-364344-A1 (ES)
Title: Apparatus for heat-shaping thin-walled containers of plastics material
IPC: B29C51/02
Filed: 1969-03-03
Abstract: In a process for heat-shaping thin-walled containers of plastics material, the latter in mouldable form is fed through an upper piston 4, Fig. 3, into the space defined between it, a piston 3 and a ring 1 the piston 3 is then raised, Fig. 4, to compress the material into a diaphragm which flows into a slot in the inner periphery of the ring whereby the diaphragm is supported for subsequent shaping by a die 10 and plunger 9, Fig. 7. Final shaping to the die cavity is effected by inflation or vacuum. During the final shaping, the container so formed is severed from the diaphragm, thereby providing an annular waste portion 8, Fig. 13, which may form part of a freshly moulded diaphragm or may be cut from the ring by a vertically reciprocal cutter 29. The ring 1 is forced upwardly against a cavitied member 27 by its engagement with a vertically slidable spring-loaded sleeve 32, and the severed portion 8 may be removed from the member 27 pneumatically. The ring 1 may comprise a pair of superposed ring members with a slot formed therebetween, or it may be a single ring member, Fig. 15, not shown, with its inner periphery suitably slotted to co-operate with an upper annulus (40) slidable about the upper piston (16). In the latter construction an upwardlydriven cutter removes all the waste from the ring member. The lower piston of Fig. 15 includes a vertically adjustable central portion (25) which may provide a diaphragm with a thicker or thinner central area such portion may be heated to a different temperature than the remainder of the piston. A number of rings 1 may be located in apertures spaced around a rotary plate 2 driven intermittently to convey the rings in turn from a diaphragm forming station, a container shaping station and a waste ejection station. Alternatively, the rings 1 may be fed linearly from one station to the next.

As shown, the spindle 7 is screwed into a baseplate 5 which is secured by screws 6 to the rear wall 2 of an air duct, the closure 3, in the form of a circular plate 12 with an annular sealing gasket 15 made e.g. of foam rubber, being secured to an annular plate 16a which carries a cylindrical sleeve 16 having an internal diameter slightly larger than the external diameter of a cam head 9 secured adjacent the outer end of the spindle 7. When the closure 3 is moved towards its closing position by pulling on a pair of rods 18 secured to the sleeve 16, inwardly projecting ends 20 of the rods 18 pass through an aligned pair of axially extending-slots 27 in the cam head 9 and when the closure element is rotated clockwise, ride up oppositely inclined semicircular cam surfaces 25, 26. The rod ends 20 engage in the appropriate pair of notches 28, in the cam surfaces, when the closure 3 tightly seals the opening 4. Apertures 17 in the sleeve 16 register with diametral passages 20 at the end of the spindle 7 for fitment of a customs seal.

Title: Means for guarding needle latches of circular knitting machines
IPC: D04B9/00
Filed: 1970-04-23
Abstract: In a circular knitting machine there is provided a latch guard devoid of feeder receiving slots but formed instead at a knitting station or each of a plurality of knitting stations with a slot just wide enough to receive a yarn and permit two yarns to pass during a yarn change. Thereby the risk of the latches of latch needles becoming damaged by swinging into latch guard slots during operation of the machine is avoided.

Title: Apparatus for producing tones of a musical scale
IPC: H03K23/68
Filed: 1972-06-30
Abstract: A digital generator for producing from a single oscillator all the tones of a musical scale uses a number of serially connected tone converters, each producing an output tone one-half tone lower than the input tone applied to a particular converter. The converters are made up of a number of serially connected digital frequency dividers arranged in groups. Each group is connected to a logic gate. The logic gates are serially connected to an additional logic gate having an input connected to the input of the converter. At the output of the additional logic gate a tone will be produced that is either one-half tone or a whole tone lower than the frequency of the input tone to the converter.

Patent ES-441130-A1 (ES)
Title: Fuel rod leak detector
IPC: G01T1/167
Filed: 1975-09-19
Abstract: A typical embodiment of the invention detects leaking fuel rods by means of a radiation detector that measures the concentration of xenon-133 (Xe133) within each individual rod. A collimated detector that provides signals related to the energy of incident radiation is aligned with one of the ends of a fuel rod. A statistically significant sample of the gamma radiation ( gamma -rays) that characterize Xe133 is accumulated through the detector. The data so accumulated indicates the presence of a concentration of Xe133 appropriate to a sound fuel rod, or a significantly different concentration that reflects a leaking fuel rod.

Title: Use of ozone treated chemithermomechanical pulp in a high bulk tissue papermaking process
IPC: D21H11/00
Filed: 1976-03-03
Abstract: Soft, absorbent, bulky paper web useful in tissue, towel, sanitary, and like products. The web is formed by supplying an aqueous furnish which includes thermomechanically defibrated pulp in admixture with chemically defibrated pulp to a foraminous surface such as a Fourdrinier wire, transferring the moist web to an imprinting fabric, thermally drying the web without mechanical compression to a consistency of from about 30 percent to about 98 percent, imprinting the pattern of the fabric into the thermally predried web, and finally drying the web. The resulting web has relatively high tensile strength at relatively low density. Also, the strength properties of the web are significantly improved if the thermomechanically defibrated pulp is made from wood chips which have been soaked in chemical solutions prior to defibrating and then treated with ozone after defibrating.
Patent ES-448169-A1 (ES)
Title: Weight and pressure operated well testing apparatus and its method of operation
IPC: E21B34/10
Filed: 1976-05-21
Abstract: A method and apparatus are presented which are particularly useful in testing the production capabilities of offshore oil wells. The apparatus includes a normally closed, weight operated valve which opens a preset delay after the weight operated valve is subjected to sufficient weight such as when a test string is set down upon, and supported by, a packer isolating an underground formation and a normally open, weight and pressure operated valve which closes immediately when the test string is set down upon the packer. The weight and pressure operated valve expands a sealed chamber when subjected to sufficient weight to close its associated valve. The weight and pressure operated valve also includes a pressure responsive piston which opens and closes the valve, and which is responsive to the pressure in the sealed chamber, and to fluid pressure in the well annulus. Thus, when the pressure in the annulus acting on the piston, aided by the low pressure in the sealed chamber, is sufficient to overcome the weight of the test string acting on the closed weight and pressure operated valve, the valve will move from its closed to its open position, thereby allowing a testing program to be conducted by increasing and decreasing the pressure in the annulus. Also included in the test string is a collapsing slip joint which allows movement in the test string in order that the pressure responsive piston may move to operate the weight and pressure operated valve in response to pressure changes in the annulus.

Title: Bread bakery proving chamber for dough pieces before baking - intermittently advances loaded trays through all zones of chamber
IPC: A21C13/02
Filed: 1978-05-05
Abstract: The chamber is of the type in which trays loaded with dough pieces are carried through the chamber by an intermittently advancing conveyor. The loaded trays are introduced at a loading module and are conveyed alternately up and down by vertical chains in each of successive processing modules. Transfer between modules is by means of horizontal chain conveyors synchronised with the vertical conveyors. Trays are transferred from the last of the processing modules to a discharge module. The discharge module has a drive unit quite independent of the drive to the loading and processing modules and provision is made for an operator to have access to the trays during their vertical transit in the discharge module. All loaded trays progress through all parts of the proving chamber, so all dough pieces receive identical treatment. Intermittent progression allows more compact construction than provers with continuous conveyors.
