Patent ES-337228-A1 (ES)
Title: Blind fastener
IPC: F16B13/06
Filed: 1967-02-24
Abstract: Masonry anchor comprising a bolt 12, an expander wedge 14a, and a shell comprising two tubular parts 18 and 28 connected to each other by a plurality of skewed struts 21. The wedge is drawn into the shell by rotation of the bolt. As the bolt is tensioned and longitudinal compression is thereby applied between the ends of the shell, the struts initially resist deformation and the wedge expands the adjacent tubular part to lock the anchor in a borehole. With increasing compression, as the bolt is tensioned further, the struts collapse longitudinally by increasing the degree of skew of the struts and decreasing the axial length of the shell without expanding radially. The shell thereby no longer supports any substantial longitudinal thrust. The struts are arranged tangentially to the bolt so as to engage the wall of a borehole and prevent rotation of the anchor as the bolt is initially rotated. The wedge is held against rotation by a projection 14b engageable in a slot 16. In a modification, the end of the bolt member remote from the wedge is threaded to receive a nut for tensioning the bolt member. In another modification (Figs. 12-14, not shown), the bolt member is provided with an extension (41) which is engageable by a pull-gun for tensioning the bolt member, but which breaks off with increasing tension once a tension retaining collar (13c) has been swaged into annular grooves (30) provided on the bolt.
Patent ES-339463-A1 (ES)
Title: Processing of Starch-Containing Foodstuffs.
IPC: A23L7/109
Filed: 1967-04-18
Abstract: A process of preparing a sterilised food product having a hydrated starchy product in the form of separate grains or strands as the only or main ingredient comprising filling containers with the starchy product in a substantially non-hydrated state with other ingredients, if used, and with a quantity of water just sufficient to substantially completely hydrate the starchy product when cooked, thereby leaving a head space in each container permitting substantial mixing of its contents, sealing the containers, agitating the filled and sealed containers under heating conditions until the sterilisation temperature has been substantially reached so that adequate mixing is effected in the containers and the desired sterilisation temperature is reached throughout the containers before the liquidity of the contents of the containers is lost by the complete hydration of the starchy product. The container is preferably agitated during all steps (e.g. cooling) subsequent to the contents reaching the sterilisation temperature. The container may be agitated by rolling it, rotating it end over end, or causing it to move in a circular path while confined within a rotating enclosure. The starch-containing material may be immersed in hot oil (e.g. groundnut oil) prior to being introduced into the containers. The starch-containing material may be rice, barley or wheat grains, macaroni, spaghetti or noodles. The food product introduced into the container may comprise in addition to the starch-containing material, pieces of meat or fish, onion, spices, fat and tomato sauce.

Title: Improvements in Fastening Means
IPC: F16B13/00
Filed: 1967-10-05
Abstract: A fastening means for use in masonry comprises a fixing element 1 in the form of a masonry drill the stem of which is provided at one end with two opposite flat surfaces 4 shaped to form a drill tip 3 and is tapered inwardly from said one end, and an expanding sleeve 10 intended to surround the element 1 when the latter is in place in a bore drilled in masonry, the sleeve having an internal taper so that by forcing the sleeve over the tapered portion of the element 1 the sleeve is spread outwardly into engagement with the wall of the drill bore to secure the element therein. The drill end of the element 1 has part conical surfaces extending between said flat surfaces. The sleeve may have longitudinal slots 12 and may be provided with a collar at its outer end. The outer end of the element may be shaped to form a shank to fit a drill chuck and it may have a point 9 of weakness between the shank and stem.
Patent ES-347926-A1 (ES)
Title: Vehicle-lifting jacks
IPC: B66F3/00
Filed: 1967-12-04
Abstract: A lifting jack comprises an upright column 1 mounting a sliding carriage 2 with two oppositely placed walls having openings 2a with oblique running surfaces 3 sloping towards the column 1 in an upward direction. In the openings 2a is a drive roller 4 with guide collars 4a, 4b and smooth end journals 6, 6a which run against the surfaces 3. The central section of the roller 4 has helical teeth 9 which bite into the column 1 when the roller 4 is turned under load by a bar or crank in an eye 5. Instead of having teeth 9 the roller 4 may be knurled. The toothed surface of the roller 4 is harder than the part of the column 1 it engages. The carriage 2 has an abutment 8 to lift the load. The first time the jack is used the teeth 9 bite corresponding recesses in the column 1, a positive engagement being obtained which prevents sliding. The angle of the surfaces 3 is so chosen that the jack is self-locking. A spring 7 continuously presses the roller 4 upwards.

Title: Ultrasonic delay line and method of manufacturing an ultrasonic delay line
IPC: H03H9/36
Filed: 1967-12-26
Abstract: A delay line, Fig. 3a, comprises a glass body having plane parallel end surfaces to which are attached transducers t 1 , t 2 , a further plane surface 5 being perpendicular to the end surfaces. The transducers t 1 , t 2 are polarized in directions P which are parallel to their respective end surfaces and are also parallel to the surface 5. The dimension of the glass body measured in the direction perpendicular to the surface 5 is less than any dimension of that surface. In manufacture, two such delay lines are produced simultaneously by sawing in half the glass body shown in Fig. 3b having the transducers attached thereto, the saw cut forming the surfaces 5 of the delay lines. The glass body may have fluted surfaces, as shown, to absorb divergent vibrations. In another embodiment, Fig. 4b, two delay lines of polygonal shape are produced by sawing the glass body along plane 5.

Patent ES-411915-A1 (ES)
Title: Drilling apparatus and adaptor assembly for such apparatus
IPC: E21B21/02
Filed: 1973-02-22
Abstract: The invention relates to drilling apparatus having an inner drill string and a surrounding outer drill string, which strings can be advanced simultaneously.

Conveniently, such zones are formed by stiffening rings permanently connected to the main bulk of the sealing ring.
Patent ES-443705-A1 (ES)
Title: Methods and apparatus for constructing tunnels
IPC: E21D11/10
Filed: 1975-12-19
Abstract: In a tunnel driving apparatus which employs hydraulic rams for advancing a shield in the direction of tunnel advancement, a thrust ring is used as a support for the rams. Lining sections are installed at the rear side of the thrust ring as the latter is shifted up. These lining sections are each spaced from the exposed tunnel wall when installed to receive fluid concrete used to form a tunnel lining. The thrust ring defines chambers, one of which has filter means which faces the concrete reception space and contacts the concrete therein. Water is withdrawn from the concrete by suction created by reducing the pressure in the chambers and the other of the chambers is used to collect the water. Inflatable packings are used to seal off the concrete reception space and can be deflated when the thrust ring is shifted up.
