Patent GB-828030-A (GB)
Title: Transducer for measuring pressure or differential pressure
IPC: G01D5/20
Filed: 1957-11-12
Abstract: 828,030. Pressure transducers. SIEMENS & HALSKE A.G. Nov. 12, 1957 [Dec. 27, 1956], No. 35163/57. Class 40 (1). A pressure transducer comprises a permanent magnet moving, in accordance with variations of pressure, within a magnetic circuit having four polepieces, so that in each extreme position of the magnet two of the poles are approximately opposite the poles of the magnet ; the polepieces are joined in pairs so that the one opposite one pole of the magnet in one extreme position is joined to the one opposite the other pole of the magnet in the other extreme position; the two pairs of polepieces are connected by a yoke on which is an energized winding. Displacement of the permanent magnet then produces a linear change of flux and linear variation of current in the winding. In Fig. 1 the diaphragm 2 is deflected in accordance with the pressure difference between the two parts of the chamber 1, and the movement is communicated to the permanent magnet 6 which is normally in the position a-a. The flux passing between the polepieces 8, 9, 10, 11 is thus changed, and the flux variation in the yoke 14, 15 is sensed as altered inductance of the windings 16, 17, which are supplied with alternate half-cycles of the A.C. supply 20 via the rectifiers 18, 19. When the permanent magnet is in its central position no flux due to it passes through the cores 14, 15. The positive half-cycle of current is sufficient to saturate the core, whereas the negative half-cycle is reduced by the inductance of the core, so that the meter 22 shows a positive reading which is the difference between the mean values of the two half-cycles. Movement of the permanent magnet causes flux to pass through the cores in one direction or the other, producing unequal effects on the two halfcycles of current and altering the meter reading. In a modification (Fig. 2, not shown), the meter is replaced by an amplifier (preferably a magnetic amplifier) whose output is passed to a further winding on the limb 13 to provide a flux equal and opposite to that due to the permanent magnet. A meter registers the current through this winding. This arrangement is insensitive to changes in frequency and temperature. In either circuit the meter can be replaced by a regulating device.

A camera has a depth of field scale visible in the viewfinder, and coupling means between the indicator on the said scale and a diaphragmsetting means so that the depth of field indication is adjusted in accordance with the diaphragm aperture setting. In the embodiment shown in Fig. 1, a shutter release member (not shown) engages a plate 8 on which are mounted a rod 5, a disc 5b, and an exploring cam 6 for an exposure meter pointer 2a. Disc 5b is engaged by arms 10a of a lever 10 pivoted at 10b, the other end 10c of which is engaged by the ends of double armed levers 11, 12 spring-urged by spring 13. The other ends 11b, 12b of the levers are disposed over a depth of focus scale 14. As plate 8 is lowered by means of the shutter release, a) pointer 2a is explored by cam 6, b) disc 5b moves lever 10 and levers 11, 12 to indicate a depth of focus depending on the position of pointer 2a, c) the diaphragm aperture is set by known means to a position also depending on pointer 2a, d) the shutter is released. The scale 14 is slidably mounted, and is movable by means of lever 16 and pin 18 as the camera objective is focused so that its position relative to index 19 gives the distance setting. The exposure meter galvanometer 2 can be rotated to allow for shutter speed and film sensitivity. The scale 14 and its indices are visible in the viewfinder field. The levers 11, 12 may be replaced by a "scissor" lever construction. In another embodiment each depth of focus indicator is mounted on a rack and linked by gears and a cable to the diaphragm-adjusting means. In the embodiment shown in Fig. 4, the position of a rack 50 depends on which of various interchangeable lenses is being used. Movement of the rack rotates, through gear 51, plates 53a, 53b to bring a particular cylinder 54, 55, or 56 into engagement with gearing 60 of a diaphragm control system and adjacent scale 63b. Considering cylinder 54, index 54a indicates the distance setting, and cams 54b the depth of focus. When the lens is focused the scale 63b is adjusted by means of pin 66a.

Title: An improved process for the production of alkali orthophosphates
IPC: C01B25/30
Filed: 1934-12-10
Abstract: Alkali meta- or pyro-phosphates, which may contain orthophosphate or be dissolved in a mixture of the corresponding acids, are converted into alkali orthophosphates by being intimately mixed at ordinary pressure and while at temperatures above 250 DEG  C. with such quantities of water, aqueous phosphoric acid, or phosphate solutions, that, after the evaporation occurring during hydration, there still remains a slight excess of water.  Examples relate to the treatment of the product obtained by heating together potassium chloride and phosphoric acid, the resulting hydrated salt obtained in one instance being the acid salt KH2PO4.H3PO4.  Residual pyrophosphate may be removed from the hydrated salt by recrystallization, and the mother liquors then obtained be used for hydrating further quantities of meta- or pyro-phosphates.  The process may be applied to the hydration of ammonium meta- and pyro-phosphates.
