Title: Improvements in belt feed mechanism for automatic firearms
IPC: F41A9/30
Filed: 1952-03-26
Abstract: 712,890. Ammunition belts; belt-feed mechanism. BREVETS AERO-MECANIQUES SOC.-ANON. March 26, 1952 [March 27, 1951], No. 27423/53. Divided out of 712,867. Class 92(2) An ammunition belt of the disintegrating link type is fed towards the breech of the gun by a driven rotor and the links are stripped from the cartridges by means comprising a radial abutment 62 for those cartridges still engaging the rotor and held by at least one link of the belt, and a pulling hook 51 carried by a part, such as a lever 50, capable of being pushed back by the cartridge about to be disengaged. The pulling hook is returned to its initial position, as by a spring plunger 54, to engage the next link, at the end of every feed step. In the construction shown the abutment 62 is in the form of part circular ramps, and the hook 51 has an upper inclined surface which, in conjunction with a sloping surface 56, directs the separated links towards a discharge shoot 59. The surface 56 also acts as an abutment for limiting the movement of the lever towards the rotor. Two levers 50 with inwardly directed hooks may be provided, and as the belt is advanced by the rotor the hook or hooks engage the links while the horizontal branch of the lever, or each lever, are engaged by the cartridges which swing the lever, or levers, to the position shown in Fig. 3. The links may be constructed as shown in Fig. 7, having forward elements 58a, 58b, and a rear element having flanges 57a, 57b, adapted to overlap the inner edges of the front elements of the following link. By this means, the action of the hook 51 on the front edges r of a link assists in pulling off the rear element of the preceeding link. A spring- controlled cam device 60 may be mounted on the shaft 32 of the rotor and comprises two fingers which are first deflected, against the action of a spring 61, by a downwardly moving cartridge and are subsequently urged by the spring to so push the cartridge towards the firearm. The arrangement is such that the cartridge c, Fig. 3, which is in the waiting position is not subjected to any downward pressure. Specifications 681,971 and 712,867 are referred to.

Title: Improvements in or relating to spent pickling acids
Inventor: HONEYMANN ALLAN JAMES KNOX
IPC: C01G49/14
Filed: 1952-11-01
Abstract: Sulphuric acid is recovered from waste pickle liquor by adding concentrated sulphuric acid, e.g. B.O.V., so as to precipitate ferrous sulphate, withdrawing the precipitated ferrous sulphate together with an amount of acid substantially equal to that contained in the waste pickle liquor treated, evaporating the remaining mother liquor by the application of heat utilizing the steam thereby generated for heating the pickling liquor in the pickling stages and the concentrated acid for further precipitation of ferrous sulphate, separating the acid from the withdrawn ferrous sulphate, and using said acid in the pickling stage.  The waste liquor may have a concentration of 12 per cent and its concentration may be raised to 55 per cent.  The waste liquor may be added batchwise so that concentrated sulphuric acid, and the mother liquor remaining after the separation of ferrous sulphate evaporated in situ, e.g. by means of a steam coil. Alternatively the mother liquor may be concentrated in a separate vessel, and the reconcentrated acid returned to the precipitating vessel, enabling the waste liquor to be added continuously.

Title: Printing mechanisms for calculating and like machines
IPC: G06C11/06
Filed: 1950-11-10
Abstract: 707,645. Typewriters &c. OLYMPIA WERKE WEST GES. Nov. 10, 1950 [Nov. 10, 1949], No. 27575/50. Class 100 (4) A printing mechanism for calculating and like machines adapted to operate at high speed comprises a circular sector-formed type carrier 6 mounted at its lower end on a radial arm 7 for rotation about a pin 8, the type sector being provided with a concentric slot 12 within which a printing lug or hammer 13 is received. As shown the type on the type-sector 6 is selectively swung into position for printing by a pivotally connected push-rod 5 attached to the machine selecting rod 1. A stop 29 on the rod 5 thus releases a lever 27 which turns clockwise to latch the end 21 of a lever 20 pivoted at 19. Rotation of an operating cam 31 by a machine operation causes a stop 35 thereon to engage the arm 26b of a bell crank lever 26 so that a knee joint formed by an arm 26a of the lever 26 pivot 24 and arm 23a of angle lever 23 is straightened. Arm 22 of lever 23 is bent over to engage a further lever 20. The straightening of the joint thus effects an anti-clockwise movement of the lever 20 whose end 17 releases an impression effecting lever 15 which has the hammer 13 engaging in the slot 12 in the type-sector 6 and which is rapidly operated by a long spring 16. The levers 15 for the various columns are guided laterally by a comb 34 mounted on a lever so that after impression, when the cam 31 is making a return movement, link 32 pivots the comb 34 anti-clockwise restoring levers 15 to normal. Stop 35 releases lever 26 and knee joint 26a, 24, 23 takes up its bent position whereon end 17 relatches the lever 15. Link 5 restores lever 27 to normal. The type-sector 6 pivots on the pin 8 slidably mounted in a guide 10 arranged so that at the moment of printing the centre line of the mouth of the U-shaped slot is substantially in line with the centre of the platen and the position at which the type strikes the platen for printing. In an alternative form the pivot 8 may be mounted on the end of a short lever.

Title: Directive aerial
Inventor: STAADEN CORNELIS AUGUSTINUS VA
IPC: H03K23/00
Filed: 1955-10-03
Abstract: 842,351. Directive aerial systems. HOLLANDSE SIGNAALAPPARATER N. V. Sept. 19, 1956 [Oct. 3, 1955], No. 28109/55. Class 40(7). A directive aerial system capable of producing beams of two different shapes and of performing two different types of scanning motions comprises two electromagnetic wave radiators 105 and 107 producing respectively, beams of the required shape polarized at right angles to one another the radiators being positioned with respect to an auxiliary reflector 106 (situated at the focus of a beam concentrating device such as a reflector 101) which transmits waves having the polarization produced by the radiator 107, and reflects waves having the polarization produced by radiator 105 by producing a visual image of the latter also situated at the focus, so that with either radiator in use a narrow beam is produced by the system without the need for changing radiators such that each is physiccally situated at the focus. To reduce energy losses caused by the radiator 105 (and its waveguide feed 104) being in the field of radiator 107 and in its own reflected field, the arrangement shown in Fig. 3, in which the auxiliary reflector 306 is inclined to the axis of the reflector 301 and the radiator 305 positioned outside the produced beam, may be employed. The scanning motions produced by the system are (1) a conical "pencil beam" scan produced by eccentrically rotating radiator 107 (307) about the axis of reflector 101 (301) and (2) a linear scan with a "beaver tail" beam produced by causing the waveguide feed 104 (304) and radiator 105 (305) to swing about an axis parallel to the broad side of the beam by supplying guide 104 (304) from a fixed waveguide 302 via a hinged waveguide joint 303 (Fig. 3) which, in the construction of Fig. 1, is situated on the side of reflector 101 which is remote from radiator 105 (Fig. 2 not shown). Such scanning results in a variation of the terminating impedance of the waveguide and to avoid this the auxiliary reflector 406 (506) may be supported and carried by the swinging waveguide 404 (504) as shown in Figs. 4 and 5, or as shown in Fig. 6 in which the portions of the radiators 605 and 607 are received, the polarization effect of the auxiliary reflector 606 being also received. Instead of employing movement of the radiators to produce the scans, the latter may be fixed and the required scans produced by suitable movement of the auxiliary reflector. A constructional form of beam concentrating device consisting of two sets of mutually perpendicular conductors having an overlapping common area is described with reference to Fig. 7 (not shown). Specifications 753,038 and 753,039 are referred to.
