Title: Improvements relating to feed-water supply systems of steam power plants
IPC: F22D11/06
Filed: 1930-10-30
Abstract: In a boiler feedwater supply system, the flow of water from the main feed pipe p back to a feed tank t when there is an excess of water in the condenser, and from the feed tank through a pipe r to the condenser when there is a deficiency of water is controlled by a servo-motor comprising a valve e, which controls the water inlet and outlet ports of the motor h, and which is mechanically connected to the piston rod f of the motor.  The valve e is actuated by a float a in a chamber b in communication with the bottom of the condenser. When the float falls, pressure water is admitted below the piston g of the motor through branch pipe v and port 2.  The upward movement of the valve y, m connected to the piston closes the connection between the main p and the tank and opens the connection between the tank, the pipe r opening into the condenser.  Downward movement of the <PICT:0360184/III/1> piston due to the rising of the float opens the communication between the main and the tank and closes communication between the tank and the condenser.  The float lever j is pivoted to the piston rod f and to the rod of the valve e. Movement of the piston by hydraulic pressure so moves the valve e as to bring it back towards its normal position.

Title: Improvements in or relating to the treatment of complex ores containing zinc
IPC: C22B3/46
Filed: 1923-12-31
Abstract: Complex zinc ores, which need not be roasted, are treated with hydrochloric acid containing free chlorine obtained at a later stage of the process, instead of with hydrochloric acid alone as in the parent case.  The free chlorine attacks the gold and part of the silver.  The gold chloride dissolves with the other metal compounds and the silver chloride is dissolved by magnesium chloride.  The solution is treated with carbonic acid in presence of an excess of ore to separate calcium as carbonate, and the liquor is rapidly decanted leaving the ore behind but carrying off the calcium carbonate in suspension.  The calcium carbonate is filtered off and the solution is treated with magnesium sulphate to separate lead, with copper to obtain metallic gold and silver, and then as described in the parent case to obtain zinc oxide or carbonate and a residual solution of magnesium chloride which is converted into magnesium oxychloride.  The oxychloride is calcined with the admission of the requisite quantity of air to yield a mixture of chlorine and hydrochloric acid for use again.

Title: Improvements in or relating to the production of photographic sound records
IPC: G03C5/14
Filed: 1930-10-30
Abstract: 366,505. Optical sound recording and reproduction. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Oct. 30, 1930, No. 32683. Convention date, Nov. 11, 1929. Drawings to Specification. [Class 40 (ii).] Relates to the production of sound record films of the kind in which the width of a photographic image varies in accordance with the sound recorded. According to the invention, in order to avoid distorted reproduction of high-frequency sounds, arising from the fact that the light slit necessarily has an appreciable width, and so produces overlapping images of wave form, the film is developed only to such an extent that the image has the appearance of a " core " of uniform blackness fringed by a border, the density of which gradually decreases towards the outer edge. Thus, instead of following the usual process of carrying the development so far that both the core and the border zone show a maximum blackening, the photographic treatment is such that the blackening of every part of the image is directly proportional to the intensity of exposure to which it is submitted. Diagrams are given to illustrate the principles of the invention. The Specification as open to inspection under Sect. 91 (3) (a) states also that the desired result may be obtained not only " by the duration and character of the photochemical treatment of the film " but also " by means of the degree of exposure, or by both together." This subject-matter does not appear in the Specification as accepted.

Abstract: 1414642 Liquid level indicators; pressure sensors W F CONTROLS Ltd 26 Sept 1973 [13 July 1972] 32741/72 Headings G1H and G1L To sense fluid-pressure, a pressure transmitting device is provided having a mounting block 20, a nozzle 26 and a convoluted diaphragm 22 to which the fluid-pressure is applied, and a fluid such as air under pressure is supplied via inlet 34, passages 26f and passages 20e in the block to the sealed space between the block and the diaphragm to balance the fluid-pressure applied to the diaphragm, excess air leaking away through a central bleed orifice 26b and a bore 26c in the nozzle at a rate determined by the position of an obturating member 24 mounted in a recess in the diaphragm and having a major surface in the datum surface of the diaphragm, the pressure of the air upstream of the nozzle being sensed as a measure of the position of the diaphragm and thus of the fluid-pressure applied to it. An O-ring 28 between the block 20 and nozzle 26 ensures that air is only bled through the orifice 26b, and the nozzle may be threaded into the block to be adjustable relative thereto. The diaphragm 22 may be of stainless steel and the tip 26a of the nozzle may be partly spherical and polished. If the transmitting device is placed at the bottom of a vessel (40), as in Fig.2 (not shown) it can be used in conjunction with a pressure indicator (50) to measure the level of liquid in the vessel. If the vessel is a pressure vessel a second transmitting device can be positioned above the liquid level to determine static pressure, the two transmitting devices in this case being connected to a differential pressure indicator (52) to provide a measure of liquid level.
