IPC: F41G1/01
Filed: 1951-09-18
Abstract: 693,474. Smallarm sights. SARVIS, H. C. Sept. 18, 1951, No.-21844/51. Class 119 Both the front and rear sights of a gunsight combination present to the vision, from the sighting position, two opaque straight branches forming a V, the V-shape of one sight being turned through 180 degrees relatively to the other, the two sights being so mounted on a gun that, by means cf visual and vernier actuity, their branches can be aligned to produce an X-shaped sighting picture, the centre of the X providing the point of aim on the target. In Fig. 1 the foresight consists of a base plate 11 and two legs 13 of thin material placed edgewise to the line of sight so that all that can be seen are two converging lines. The rear sight presents two legs 17 carried by a frame 18 and so constructed that it and the foresight have the appearance shown in Fig. 11 when not aligned and that shown in Fig. 12 when aligned. A screw 22, Fig. 4, projecting from the frame 18 receives a plate 23 and nut 24, the plate having an edge 25 which combines with an edge 21 on the base 19 of the frame to clamp the structure to a carrier 20. The carrier has reference markings 31 and is secured to the barrel 12 by screws 34. In a modification, sight lines are drawn, engraved or otherwise marked on sheets of transparent material constituting the front and rear sights, or fine wire is incased between two connected sheets of transparent material. In another modification, Fig. 7, the sight 17 is mounted on an inclined platform 41 having ends 42, 43 which engage the barrel, and holes for the heads of screws which screw into a plate 46 and serve (a) to tighten a clamping strap 44 to the barrel and (b) to. draw the ends 42, 43 into firm contact with the barrel.

Title: Process for the preparation of derivatives of phosphorous acid
IPC: C02F5/14
Filed: 1962-06-07
Abstract: A process for the preparation of a phosphonic acid containing at least two phosphorus atoms comprises treating an acylation product of phosphorous acid, subsequent to its formation, with water at an elevated temperature, preferably above 60 DEG C. and expediently below 160 DEG C., steam being used above 100 DEG C. Volatile products may be distilled off; steam used in the process may also be used to effect this. The products are believed to be of the type <FORM:0978297/C1/1> R being the residue of the carboxylic acid RCOOH. The products may be converted into alkali metal or ammonium salts. The acylation products may be prepared by the reaction of phosphorous acid with a carboxylic acid halide or anhydride or mixtures thereof or from PCl3 and the carboxylic acid. Examples describe the preparation of products from phosphorous acid and acetyl chloride, acetic anhydride, mixtures of acetyl chloride and acetic anhydride, propionic anhydride, butyric anhydride, caproic acid chloride and acrylic acid chloride.  Salts are prepared in some cases.

Abstract: 1428258 Domestic refuse compactor MAXON INDUSTRIES Inc 15 May 1973 [17 May 1972] 23011/73 Heading B8C A refuse compactor, for use as a domestic garbage can, comprises a rigid container 1, a pressure plate 6 within the container that is movable in opposition to a wall of the container for compacting refuse between said pressure plate 6 and said wall, means 11 for sealing that portion of the interior volume of the container that is covered by the pressure plate 6 against atmospheric pressure comprising a member of an air-impervious flexible sheet material carried by said pressure plate to extend beyond the periphery of said pressure plate to bear on wall surfaces of said container that are external to that portion of the internal volume of the container that is covered by said pressure plate, and a power means 13, 14 connected to evacuate air from the container between said pressure plate and said wall to bias said member into air-sealing engagement with said wall surfaces and to effect movement of said pressure plate for compacting refuse. As shown, a removable lid 3, having a skirt 5 to engage the upper rim of the container, accommodates the plate 6 when the latter is retracted, by three reel tapes 7 and associated constant-tension spring rolls 8, into the lid, and also an electric motor 12 and vacuum pump 13 the input of which is connected to a sprial of flexible tubing 14 having its other end connected to an opening 15 in a disc component 9 of the plate 6. The pump 13 discharges, at 16, directly into the space between the lid 3 and the plate 6 the said space communicating with atmosphere through openings 17 in the lid. The L-shaped sealing member 11 has one limb clamped between the disc 9 and an associated corrugated face plate 10, the other limb resiliently engaging the container wall. The face plate 10 has a series of openings 21, a relief opening 18, controlled by a solenoid valve 19 being provided in the disc 9. To operate the compactor a timer switch (22) in a control circuit, Fig. 4, not shown, is switched on by a key (23) to energize the motor (12) so that the pump (13) draws a vacuum in the container space below the pressure plate 6 which consequently is urged downwardly, by atmospheric pressure, acting upon its upper face, the relief opening 18 being closed by the solenoid valve 19 which is connected in the circuit of the motor 12. The control circuit includes microswitches (25) which switch off the motor (12) if the plate 6 tilts excessively and microswitches (27) which prohibit the energizing of the motor 12 when the lid 3 is not properly fitted to the container. In a modification, Fig. 5, the pressure plate 29 is connected to the lid 31 by a flexible bellows 30 to form an expansible chamber which is open to the atmosphere through an opening 32, vacuum being suppliable to the whole interior of the container 1 by the vacuum pump 13 connected to an opening 34 in the cover 31 which sealingly engages the container 1.
