Title: Improved method of treating the residual gases of superphosphate manufacture
IPC: C01B33/10
Filed: 1935-08-17
Abstract: The residual gases from superphosphate manufacture are passed over lead or material containing lead, water being initially sprayed over the lead with circulation of the solution obtained over the plumbiferous material.  Lead silicofluoride solution and a residue of silica are produced.  The gases and solution may flow in counter-current in a tower in which metallic lead is contained in a series of vessels provided with perforated bottoms, and standing in a bath of solution in which the silica is deposited. Old accumulator plates, preferably in alternate piles of positive and negative plates, may replace the metallic lead. Specification 440,629 is referred to.

Title: Regulation of the current supplied to a field winding of an electrical machine
IPC: H02P7/282
Filed: 1978-05-26
Abstract: The excitation current (iE) which flows through the excitation winding (14) of an electrical machine, especially of a DC machine (16), is supplied from a reversible converter (2) having two converter elements (4, 6) whose drive units (34, 36) are connected to in each case one controller (28, 32). In order to ensure stable control operation and free parameter adjustment on the controllers (28, 32),   a) a resistor (20) is connected parallel with the excitation winding (14) and b) the magnitude (iE) of the excitation current is connected to both controllers (28, 32) as a single, common actual value.   The latter measure always results in a loop current with gaps, as a result of which the loop circuit has a small path gain. The resistor (20) is used for stabilising the control operation. The two measures enable continuous field control. <IMAGE>

Title: Improvements in or relating to the measurement of the flow of particulate material
Inventor: BECK MAURICE SIDNEY
IPC: G01F1/66
Filed: 1968-05-17
Abstract: 1,270,112. Electro-physical measurementflow. NATIONAL RESEARCH DEVELOPMENT CORP. May 14, 1969 [May 17, 1968], No. 23585/68. Heading G1N. In a method of measuring the mass flow rate of hydrodynamically conveyed particulate material a signal related to the flow noise of the material is produced and measured. The mass flow is shown to be proportional to the R.M.S. flow noise signal, and the noise may be detected by changes of effective dielectric constant, density or conductivity. In the former case, a part 2' of a conveyor pipe 2 is insulated from the remainder of the pipe to act as a capacitor, and is connected to a capacitance bridge 21, Fig. 2, so as to amplitude modulate an oscillator 22. The modultion is detected at 23, D. C. amplified at 24 and A. C. amplified at 26. A feedback network 25 controls the capacitance of a varactor diode in the input bridge, and produces a very small low frequency gain so that slow charges of input capacitance due to particle build up in the pipe is not registered. The A. C. output from the transducer of Fig. 2 is fed to an amplifier A1, Fig. 3, whose gain is controlled by a thermistor TH1 in a feedback network, the thermistor temperature being variable by amplifier 31 in response to changes in the bulk dielectric constant e of the material sensed by a probe (not shown) in the pipe feed or outlet. The thermal capacity of TH1 is such that only slow changes of bulk dielectric constant, due for example to moisture, affect the gain of A1. Resistors R7 and R8 are used to provide a linear gain control, and resistors R9, R10 and thermistor TH2 cancel effects of ambient temperature on TH1. The output from Fig. 3 may be squared, smoothed and displayed, as in Fig. 1, to provide a linear display on meter 9, or the squaring may be omitted to expand the lower regions of the meter readings. In Fig. 4 (not shown) the sensed bulk dielectric constant e is squared and smoothed prior to mixing with the squared and smoothed Fig. 2 signal. The mass flow is proportional to the R.M.S. noise signal only if the signal spectrum extends well above the transducer cut-off. If large particles or low fluid velocities are used, the cut-off should be correspondingly low. When the noise signal is to be derived from density changes, variations in attenuation of ultra sonic radiation are said to be usable. For Figs see next page

Abstract: 1,001,899. Warping. SCHUR UND SPULMASCHINENBAU BURGSTADT, V.E.B. June 22,1962, No. 24200/62. Heading D1M. In a yarn accumulator for warping machines, the vertically-movable rollers 15, 16 are interconnected in pairs by endless chains 12. The rollers normally occupy the mid-position as shown for the righthand pair but, when the warping machine is reversed, the yarn let back (from the right of the drawing) is formed into bights by successive displacement of the pairs of rollers. The first bight is formed by the left hand.pair, which are released by disengaging a latch 58 from a nose 57 on the bearing of the roller 15, whereupon the rollers move under the weight of the roller 16, which is heavier than the roller 15. To prevent yarn from being drawn off the creel (to the left of the drawing), a yarn brake 66, consisting of bars 64, 65, drops between fixed bars 60-62. When the rollers reach the end of their travel, a striker (not shown) on the chain 12 releases the next pair of rollers, and so on. On resumption of warping, the pairs of rollers are successively returned (starting from the right) to their mid-position, to pay out the accumulated yarn, by a motor 30 driving the chain wheels 11, one at a time, through clutches which are controlled by strikers on the chains 12; when the left-hand pair reaches its mid-position, a striker 59 depresses a nose 68 to lift the yarn brake 61 clear of the yarns.

Abstract: 425,047. Controlling air supply to stoves. BELL'S HEAT APPLIANCES, Ltd., and SCOTT, C. L., 157, Queen Victoria Street, London. Sept. 5, 1933, No. 24594. [Class 126] [See also Group XIII] In a stove, one or more thermostatic elements shielded from the direct action of the flue-gases are arranged to be responsive to variations in temperature of one or more of the cooking or other heat-consumption points and, independently, to the temperature of the firebox or barrel, solely or mainly through the medium of heat radiated therefrom, and to actuate valve means for controlling the supply of combustion air to the fire. In the form shown in the Figure, the end of a mercury-filled capillary tube 12 is located in the flue 11 in close proximity to the hot-plate 3, and is protected by a sleeve 13. The tube 12 is carried down close to the Bourdon tube 9, and then in spiral form to a point near the firebarrel 4, where it is formed into a small coil 14. Thence it is looped back on itself and is connected to the Bourdon tube, which actuates an air-valve 7 through the arm 8. A sleeve 15 shields the spiral and coil 14. In another form, a single thermostatic element has two or more capillary branch tubes, one of which is associated with the fire-barrel and the other or others with the heat-consumption point or points. Alternatively, one thermostatic element may be responsive to the temperature variations of one or more heat-consumption points, and another to firebox temperatures. The second element is so placed as to become operative at the same temperature as the first.
