Title: Improvements in and relating to eye-pieces for rifle aperture sights
IPC: F41G1/18
Filed: 1937-10-11
Abstract: 505,491. Rifle - sights. DUNN, W. Oct. 11, 1937, No. 27600. [Class 119] An aperture sight for a rifle comprises a plate 11 having parallel edges 11a and a number of apertures 11b of graded diameters, this plate being slidable in a member 7 and being retained in the adjusted position by a ball 12a which is adapted to engage one of a number of grooves 12 in the plate 11, in vertical alignment with the apertures. The plate is held in position by an apertured disc 16 subjected to the pressure of a spring 18 which is compressed by a cap 19 screwed on the member 7. If desired, an apertured disc 14 and lens 15 may be interposed between the plate 11 and the disc 16. The discs and lens have a notch at the periphery to engage a fixed pin in the member 7 to prevent rotation of the discs &c. during adjustment of the cap 19. Indications are marked on the plate 11, whereby the size of the aperture in use may be determined, e.g. either of the ti!,'11I't's 4 or 6 being visible shows that the aperture in use has a diameter of four or six hundredths of an inch, whilst no figure being visible shows that the middle aperture, having a diameter of five hundredths of an inch is in use. The member 7 has a tubular stem 8 which is screwed into a block 9 adjustable along a bar 10 for wind correction, the stem being locked in its longitudinally adjusted position by a lock-nut 21 or by an axially aligned tubular screw. Fig. 2 the parts disassembled.

Title: Purification and/or concentration of fluosilicic acid
IPC: G03C1/49
Filed: 1966-06-21
Abstract: Aqueous fluosilicic acid is purified and/or concentrated by continuously distilling it in the presence of 60-65 weight per cent orthophosphoric acid in an evaporator at a temperature maintained at at least 120 DEG  C., under atmospheric pressure, by controlling the addition of fresh fluosilicic acid solution.  The vapour from the evaporator may be passed into a rectification column from the bottom of which the concentrated fluosilicic acid is withdrawn, part of the latter being recirculated to the top of the column.  The vapour leaving the rectification column may be washed, before condensation, with a fluoride solution, e.g. ammonium, sodium, potassium, or aluminium fluoride solution, and the resulting silicofluoride solution isolated or charged into the rectification column.

Title: Improvements in or relating to the manufacture of diaphragms, filters and other porous bodies
IPC: C08L21/00
Filed: 1932-10-06
Abstract: Porous rubber compositions suitable for diaphragms, filters, &c. are prepared by mixing fibres with rubber, subjecting to a light preliminary vulcanization, grinding into flocks, mixing, and then completing the vulcanization in moulds, either without the application of pressure or with only light pressure.  Suitable fibres are asbestos, wood, hemp, &c.  These fibres are mixed with rubber either in solution, or on the mixing rolls, in the former case the solvent is removed by evaporation.  In an example 58,5 per cent rubber, 21,5 per cent sulphur, and 20,5 per cent wood flour are treated as above and when subjected to a moulding pressure of 1 gram per square centimetre yield filter plates of considerable porosity and medium breaking strength.  The amount of rubber may be varied between 65 per cent and 48 per cent, and the amount of fibre between 10 per cent and 33 per cent.  The more fibre present the greater the porosity but the less the breaking strength.  The preliminary vulcanization is carried to just such an extent that the rubber adheres firmly to the fibre.  In general, a dry vulcanization up to a temperature of about 100 DEG  C. for two hours is sufficient.ALSO:Porous rubber compositions suitable for flexible diaphragms, filters, &c. are prepared by mixing fibres with rubber, subjecting to a light preliminary vulcanization, grinding into flocks, mixing, and then completing the vulcanization in moulds either without the application of pressure, or with only light pressure.

Abstract: 944,846. Ventilators; lamps combined with ventilating means. EMERSON ELECTRIC MANUFACTURING CO. Aug. 11, 1960, No. 27892/60. Headings F4R and F4V. In a combined ventilating and lighting unit a member having a plurality of removable panels formed therein divides an upper air enclosure from a lower space in which lights are mounted so that the unit may be used as a light fixture alone or may in addition be used to provide a number of differing nodes of air flow depending on which of said panels are removed. As shown in Fig. 2, the apparatus comprises a body 12 open at its lower portion and having its upper edges bent over to define channels 19 for electrical wiring, and an air space 32 which is surmounted by a member 25 having an aperture connecting said air space with a conduit 26 or with the plenum space above a ceiling. A V-shaped member 45 having perforations 52 is mounted beneath the space 32 and is separated therefrom by a member 33. As shown in Fig. 7, this member has " knockout " panels 39, 39a in its centre panel 37 and further such panels 42 in its divergent side panels 36. The walls of the body 12 and those of the V-shaped member 45 define two parabolic reflecting compartments in which are mounted lights L, the compartments being provided with transverse partitions. In the embodiment of Fig. 2 only the panels 39 and 39a have been removed to provide communication between the air space 32 and the V-shaped member 45. This type of unit may be used to supply cold air to a room, flow of cold air over the lights L being avoided, and may be used in combination with a unit having all of the panels removed and having a hot air supply. In the modification of Fig. 9, all of the panels are removed and pivoted flap valves 71, 72 are provided, the valves being arranged for movement between one limiting position in which they close the apertures formed by the removal of the panels 42 and a second limiting position in which they isolate the member 45 from the air space 32. A perforated curved baffle 58 within the member 45 is provided to distribute the air entering the latter along its length. The unit may be used as an air extractor when its air supply is cut-off.

Convention date, Nov. 19, 1930. [Class 137.] In a ventilator intended more particularly for vehicles, in which a vane is pivotally connected with a member adapted to be moved towards or away from an opening with which the vane co-operates, said member is hingedly connected to one side of the opening and is connected to the opposite side by resilient means adapted to hold the member in adjusted position. Secured to the inner edge of a rectangular opening in the vehicle body is a frame 12 having an outwardly opening channel 13. A pair of ears 15 formed at one side of the frame 12 serve as a pivotal mounting for a hinge wing 16 provided with an adjusting lever 18 and a pair of arms 17 extending from each end of the wing to a position adjacent the centre of the opening. To the ends of a rod 21 rotatably mounted between the ends of the arms 17 are riveted brackets 19 carrying a vane 20 consisting of a flat rectangular plate slightly larger than the opening and having inturned edges adapted to coact with a gasket 14 in the channel 13 and form a watertight joint. One of the brackets 19 is extended inwardly to form an operating handle 32. By means of the handle 18 the arms may be moved to such a position that the vane closes the opening in the frame, or as shown by the broken lines in Fig. 4, the vane may be moved bodily away from the opening so that by an adjustment of the handle 32 one or other of the edges of the vane coacts with the frame 12 so that air may be injected into or withdrawn from the vehicle. The arms 17 are resiliently maintained in the closed or open positions by means of bowed springs 24 attached at one end to the side of the frame remote from the ears 15 and at the other end formed as compression springs 22 on the ends of the spindle 21 and serving to hold the vane in adjusted position relatively to the arms 17. A ventilator of this form may be provided at each side of a car behind the dashboard 33 and so adjusted that a continual stream of air passes through the car from one side to the other.
