Patent ES-335737-A1 (ES)
Title: Flow-regulating device, especially for granular products
IPC: G05D7/01
Filed: 1967-01-17
Abstract: A flow control system for granular material comprises a perforated container 1 which receives the material from a store 17 via valve 15 and shoot 19, the container being supported on knifeedges 27 suspended via universal coupling 25 from a diaphragm 22 forming part of a weighing unit 6. A pneumatic transducer 8 supplies an electric signal to a recorder 11, the latter being coupled to a relay 12 which controls valve 15 via regulator 13. By maintaining a constant level (i.e. weight) in container 1, the flow through the helical array of holes in the latter is kept constant. In a modification, Fig. 2 (not shown), the weighing unit is omitted and the level in the container is controlled by a detector (33) slidable vertically in the container. This detector may be optical (photo-electric or a gammagraphy unit), ultrasonic or a capacitance unit. An electromagnetic vibrator (31, 32) supports the container.

Patent ES-351347-A1 (ES)
Title: Improvements in or relating to Motor Pump Assemblies
IPC: F04D15/00
Filed: 1968-03-07
Abstract: An electric motor pump unit used in a central heating system has a sealed stator assembly co-operating with a rotor 10 mounted at one end of a hollow shaft 9 supported in a bearing 8 in a support plate 7 and carrying at its other end pump impeller 12, wherein a check valve 20 is provided within the hollow shaft so that the stator can be removed without draining the system. The stator assembly includes a wound core 1 secured between end plates 2, 3 and secured to the pump body by screws 19. A jacket 5 encloses the rotor and is sealed to end plate 2 and support plate 7 by seal 6. Hollow shaft 9 is supported in bearing 8 housed in support plate 7 and a thrust bearing 11 is provided between rotor 10 and bearing 8. Pump impeller 12 is mounted on end 9a of the hollow shaft and the pump chamber is closed by casing 13 which is secured by screws 17 to plate 7 and sealed by resilient ring 14. When the stator assembly is removed water pressure causes impeller 12 to be pressed against bearing 8 and valve 20 to close so leakage is minimized and rotor 10 is made accessible. In operation, the provision of back blades 12a on impeller 12 relieves the pressure on thrust bearing 11. The pump delivery is regulated by inserting shims 15 between casing 13 and support plate 7 thereby altering the volume of the pumping chamber.

Patent ES-355356-A1 (ES)
Title: Apparatus and method for producing a doupion thread
IPC: D02G1/16
Filed: 1968-06-22
Abstract: A process for the production of a knop yarn comprises introducing a core yarn and a cover yarn into a zone of turbulence, said core yarn being fed at a higher tension than the cover yarn, intermittently introducing a fluid into said zone to cause turbulence which simultaneously exerts suction on said cover yarn so that the knop effect is produced by overfeeding the cover yarn and looping it on the core yarn, and withdrawing the knop yarn from said zone. Apparatus for carrying out the process comprises a substantially rectilinear duct 12 for passage therethrough of the core yarn, and including the zone of turbulence, a second duct 13 for introducing the covering yarn and forming an acute angle with the duct 12 downstream of the zone of turbulence, and means for intermittently introducing fluid into the zone to apply suction to and cause looping of the covering yarn to produce the desired knop effect. The fluid is introduced through a duct 11 into an annular chamber having angularly directed openings 14 into the turbulent zone 15. The fluid is preferably a gas e.g. compressed air. A further yarn may also be introduced into the zone with the cover and core yarns, which cover and core yarns are preferably multifilament yarns. The fluid introduction is preferably effected at regular time intervals. The knop yarn produced may be twisted.

Title: Solid non-caking food compositions
IPC: A23L1/00
Filed: 1969-07-23
Abstract: A normally hygroscopic food is rendered less hygroscopic by intimately admixing therewith a starch hydrolysate having dextrose equivalent of 5-25 and a descriptive ratio of at least 2. The descriptive ratio is the quotient obtained by dividing the sum of the percentages of saccharides, dry basis, having a degree of polymerisation of 1-6 by the dextrose equivalent. The food may may be an acid hydrolysed protein (e.g. casein or protein derived from wheat, soya or corn), dried tomato pastes, dried honey, dried fruit purees or dried beef bouillon. The starch hydrolysate may be prepared by hydrolysing a starch (e.g. waxy, corn, potato, tapioca or grain sorghum starch) with acid or enzyme (e.g. [alpha]-amylase). The food and starch hydrolysate may be formed into an aqueous solution, suspension or paste and then dried (e.g. spray drying or drum drying).

Title: Surgical drainage system
IPC: A61M39/24
Filed: 1972-09-08
Abstract: A surgical drainage system including a container for collecting fluid drained from a cavity, such as a pleural cavity, and a drainage tube for placing the container in fluid communication with a cavity to be drained, is provided with a check valve in the drainage tube. The check valve permits the flow of fluid from the cavity to the container and prevents the flow of fluid in the opposite direction thus permitting the development of a high negative pressure in the cavity. The check valve comprises an elongate tapered tube which can be positioned inside the drainage tube with its wide end towards the cavity. The tapered tube is provided with an elongate slot lengthwise of the tube to form a liquid flow passage, the edges defined by the slot being sufficiently flexible to permit fluid to pass outwardly therethrough and to close on being subjected to a negative pressure within said tapered tube to permit the development of a high negative pressure therein.

Patent ES-433444-A1 (ES)
Title: Dot printing apparatus
IPC: B41J2/265
Filed: 1974-12-30
Abstract: Wire matrix dot printing apparatus is disclosed in which a plurality of wire impact members are driven by electromagnetic means arranged in a circular pattern at the rear of a wire matrix print head. The wires are caused to converge following the arc of free bending in the wire from the circular array at the driver end to a parallel and colinear alignment at the printing or output end of the print head. The individual wires are continuously guided from the end where the drivers are located to a point where they are nearly parallel and colinear by utilizing an improved two-piece wire guide consisting of an inner cone with grooves on its surface and an outer shell which confines the wires to the grooves in the inner cone. The shape of the inner cone is such that the paths of the wires converge from a circular array at the driver end of the print head to a nearly colinear and parallel array at the output end of the print head.
