Title: Inflatable flood water barrage - has articulated plate raised by partition ed inflatable rubber membrane
IPC: E02B7/00
Filed: 1976-04-15
Granted: 1985-04-20
Abstract: The water barrage consists of a rectangular steel plate (8) hinged longitudinally at the base (6) of a recessed foundation plinth (4) by a bracket (7). The free moving end of the plate is folded back (11) and tied by a cable (16) to the plinth, to limit the travel of the plate. A convoluted rubber membrane (12) is sealed between the free end of the plate and the lip (32) of the plinth. The membrane is divided into two portions which have separate valves (27, 28) located in the plinth. The plate is raised by inflation of the chambers with the object of restraining flood waters from reaching the upper parts of the river or estuary.

Title: Erecting method of cast-in-ground reinforced pile
Inventor: HAGINS SAULS
IPC: E02D5/42
Filed: 2001-01-10
Abstract: An invention refers to the area of building of the bases and foundations and can be applied when erecting cast-in-place piles of the monolithic concrete, which are made using strengthening tubes or other housings. The purpose of an invention is to simplify operations when passing a well in water-saturated grounds and to raise the carrying capacity of the piles. The making of a reinforced cast-in-pile (fig.3) in the ground comprises passing a well (2) in the ground (1) and strengthening the walls of the well (2) by a casing tube (3). According to the first version of an invention, the casing tube (3) is driven into ground (1) by means of a pneumopunch (4) connected to a flange (5) at the upper end of the mentioned tube (3), after which the well (2) is conditioned to remove the ground core (6), then the well is filled with a plastic hardening material (7) which is then compacted. According to the second version, the pneumopunch (4) is sunk into the well (2) by help of a cable (8), then the bottom of the well (2) is deepened below the end face of the casing tube (3) up to the design depth H, after which the pneumopunch (4) is extracted from the well (2) and the recess (9) is filled in its bottom part with a working material (10). After that the pneumopunch (4) is repeatedly immersed in the well (2) up to the design depth H, besides the number N of cycles of filling with the working material (10) and passing for the design depth H is determined from equation N=(D22-d2)/(1-Q)d2, where D2 is the design diameter of the expansion (11) of the pile, d is the diameter of the pneumopunch (4) and Q is volumetric compression ratio of the working material. After that the well is filled with the plastic hardening material (7) with its following compacting. The pile is made with the expansion (11) in the bottom part of the well (2), the expansion diameter D2 being greater than the diameter D1 of the casing tube (3). The offered versions of the technical solutions allow everyone to make a reinforced cast-in-piles with guaranteed strength characteristics practically in any soil with sufficiently high output. The piles can be made using one pneumopunch only, which allows one to make piles even in basements of old houses for underpinning their foundations.

Title: Mobile table with additional plates and heightened hardiness
Inventor: KLAVINS VILIS ARNOLDS
IPC: A47B11/00
Filed: 1994-05-20
Abstract: This invention relates to furniture for tea serving, cards playing, etc. The proposed table is easy to move on the floor. The objective of this invention is to create a movable table of increased stability, which also has additional boards. It is also compact in the dismantled state, easy to mount, and convenient to use. It is suggested to use the built-in screw, which is in the table surface, for mounting table boards, legs, and stand. The screw is safely fixed (to prevent rotation) to the vertical holed tube with thread in the upper end, which is fastened to the upper screw. It also prevents rotation of the hole with thread in the lower end, and a hole in the base with a lower screw, which is fastened to the tube's lower end. The upper screw has an angular head, which is fixed into the table board, in which the matching shape screw socket is fixed as to protect the screw from rotating. The screw end has holed flanges for the fixation of the table legs to the base and table surface board. In Fig.1 a table with four additional boards is shown, the two of those are in the working state, while the other two are in a storage state.<IMAGE>

Filed: 1986-11-28
Abstract: In a method for manufacturing a sealing ring with a sealing lip, the material forming the sealing lip is fabricated in plastically deformable condition into the shape of a column-like hollow body. Prior to solidification, the column-like hollow body is twisted between axially spaced cross-sectional planes. This forms return elements with hydrodynamic action. Subsequently, the hollow body is solidfied and its diameter is enlarged axially outside the region of the sealing lip and it is then secured in a sealing ring housing.

Abstract: Catalyst solution contaminated during the carbonylation of methyl acetate and/or dimethylether. To this end, the contaminated catalyst solution is subjected in a first processing stage to extraction with a dialkylether and alkanol, each of which has from 1-4 carbon atoms per alkyl group, and thereby freed from its organic contaminants, from acetic acid, acetic anhydride and ethylidene diacetate, and the ether phase is separated from the purified promoter-containing catalyst solution; next, the ether phase is treated in a second processing stage with iodine and/or methyl iodide; the precipitated promoter containing catalyst complex is separated and dissolved in the purified catalyst solution coming from the first processing stage; the ether phase is separated into its constituents by distilling it; recovered dialkylether and alkanol are used again in the extraction stage; fresh catalyst solution is prepared from the recovered mixture of acetic acid, acetic anhydride and ethylidene diacetate and from the united purified catalyst solution while residual dialkylether and alkanol are distilled off, and the organic contaminants retained in the residue of the ether phase distillation are expelled.

Abstract: In a container (1) of flexible material and including a tube-shaped blank divided into two opposite side walls (5) and two intermediate pairs of gusset walls (6) by means of gussets (2, 3), and having at least one block bottom (8, 9), a tightly sealed, outwardly folding discharge valve (11) is provided in the block bottom (8), said discharge valve being resealable and provided with a gripping means (16). The opening of the valve is formed by shortening a part of the folded end area to predominantly the same length as the depth (19) of the gusset (2). When manufacturing the container (1) from tubing, it is gusseted and divided into blanks corresponding to the container. Then a part of the end area of the blank is cut along a first intersection parallel and adjacent to the middle fold (7) in one of the gussets (2) when the blank is folded up, and along a second, transverse intersection (23) one gusset depth (19) apart from the fold lines (25) around which the final folding of the side walls is performed, whereupon the block bottom (8) is folded, while optionally mutually glueing or welding the folded side walls. Only the parts of the block bottom (8) not in touch with the gusset walls (6) with the cutout are optionally glued or welded. The resulting container with block bottom has a well functioning resealable discharge valve and is suitable for manufacture in a continuous process from an endless material without use of extra material.
