Title: Apparatus for determining the fraction or percent moisture removed from a traveling material
Inventor: CHOPE HENRY ROY
IPC: G01N5/04
Filed: 1969-08-13
Abstract: 1280666 Determination of moisture content and removal INDUSTRIAL NUCLEONICS CORP 13 Aug 1969 [13 Aug 1968] 40555/69 Heading G1A In the investigation of moisture removal from a travelling web, the mass per unit area of the web is measured at a first point before drying and at a second point downstream of the drying station, at which point the moisture content of the web is also measured. Signals representing these three quantities are operated on by arithmetical processing means to develop signals representing the actual moisture content at the first point, and the percentage, and the actual moisture weight per unit area removed between the two points. The invention is described with reference to a conventional Fourdrinier paper making process comprising elements 10 which include dryer sections 26-30. A conventional moisture gauge cannot accurately be used at the "wet end", I, and so only a beta-ray gauge 47 measuring mass per unit area of the paper web is used at this first point. At the "dry end", II, a similar beta-ray gauge 45 measuring mass per unit area is associated with a moisture gauge developing e.g. the percentage moisture content. The gauges scan across the web in synchronism. The dry end measurements, BW 2  and m 2  are multiplied at 53 to obtain the dry end moisture weight per unit area M 2 . This is fed with the wet end measurement BW 1  and the inverted BW 2  to adder 54 to develop M 1 , the weight per unit area of moisture at wet end I. This is indicated at 58 and also used to obtain the percentage wet end moisture, indicated at 66, by means of a divider, which also receives BW 1  -BW 2  (from adder 62) which is also indicated as the weight per unit area of moisture removed at 64. Modifications of the Fig.1 arrangement include the use of a two input adder, instead of 54, which receives M 2  and the difference output from 62. Fig.2 (not shown) details a circuit arrangement using a two-input adder instead of 54. The gauges 45 and 47 for this arrangement provide mechanical outputs controlling the settings of potentiometers in bridge circuits in accordance with the mass per unit area variations. The bridges are adjustable so that their output voltages have an equal proportionality relationship to the web variations. The voltage representing BW 2  is fed to a multiplier comprising an operational amplifier having a feedback resistor arrangement variable in steps of 10 kilohms or continuously in dependence on the percentage moisture measured by gauge 49. The output is fed to an adder with a further input representing BW 1  which takes the form of a second operational amplifier. The signal M 1  obtained is then used as in Fig.1 to obtain the percentage moisture removed.

Title: Investigation of phenomena represented by repetitive features in a transduced signal and the suppression of noise in such a signal

Filed: 1974-09-23
Abstract: 1485966 Extracting signals from noise SNAMPROGETTI SpA 23 Sept 1974 [24 Sept 1973] 41407/74 Heading G1U Data that occurs periodically at known times in a composite signal, such as D, Fig. 3, together with noise, is extracted from the noise by a process which effectively samples the noise between the occurrences of the data so as to provide a level generally indicative of the noise, and then subtracts the general noise level from the composite signal to leave the data, or rather an estimate thereof, free of noise. In more detail, the composite signal D, Fig. 3, from a transducer 1, Fig. 1, and an amplifier 2, is processed by rectifier 23 and a gate 21 to give a signal E, Fig. 3, the gate being controlled by appropriate timing pulses A' and C synchronized with the data and occurring just before the data, and the signal E is peak followed 22, G, and inte-  grated and inverted 24, H. Finally, the signal H which is indictive of the general noise level and is of negative polarity, is added 25 to the original composite signal D to give the signal L which is clipped below zero M and gated 8 by a clock signal C to reveal the data signal N, rectified, free of noise. This signal N is passed via an integrator 10 and a peak follower 11 to give the signal R, which is further integrated 12 to give the final signal T.

Filed: 1962-11-07
Abstract: 1,057,486. Making wheels; stamping; rolling metal. DUNLOP CO. Ltd. Oct. 30, 1963 [Nov. 7, 1962], No. 42017/62. Headings B3A, B3M and B3Q. [Also in Division B7] A method of making a wheel having a disc 12, Figs. 1-23 (not shown), and at least a part 18 of the rim formed as a seamless unitary structure from a sheet-metal disc-shaped blank 30, comprises subjecting the blank to at least one pressing operation to shape the outer peripheral portion of the blank to form the part 18. The apertured blank 30 (Fig. 2) is cupped in a twostage operation between dies 32-34 (Fig. 3), the flange of the blank then being hot-shaped between a roll 37 (Fig. 4) and an expansible supporting roll 35 on which the blank is held by a disc 36. A hot-pressing operation follows (Fig. 5) to steepen the outer wall 21 of a circumferentially extending gutter-groove 20 to be formed in the rim. This is followed by flaring of the rim between dies 38, 40 (Fig. 6), and then by a final hot-shaping operation between an expansible carrier roll 41 (Fig. 7), and a roll 42. Alternatively, the last rolling operation may be replaced by mounting the cupped blank on an expansible roll 43 (Fig. 8) movable horizontally to carry the blank against forming rolls 44, 45 coupled by a chain and driven by an electromotor. Instead, the gutter groove 20 may be formed by an outer roll 49 (Fig. 9) and an inner roll 48 of smaller radius A-A than that B-B of the blank. In a modification, the only rolling operation thins the flat blank towards its circumference (Fig. 10). This is followed by a cold cupping operation (Fig. 11), and a pressing operation (Fig. 12) to reduce the free edge of the rim. Hot pressing follows, forming the undercut edge of the groove (Fig. 13), then a final hot pressing with a divided die 62 (Fig. 14) which forms a rebate 64 for lapping on a similar rebate of the other sector 22 (Fig. 1) of the rim, the sections being joined by welding 24 at the lap joint. The other section 22 is produced from a cylindrical blank 70 (Fig. 15) of thickness equal to the maximum thickness of the finished section and reduced at the edges by rolls 71, 72. Two pressing stages follow (Figs. 16 and 17), after which edge 81 of the blank is rebated. If the section 22 is made from a blank of thickness equal to the thinnest section of the finished section, the thickness of the blank is increased locally by hot pressing (Fig. 18). Alternatively, a pressing operation (similar to that in Fig. 16) may be followed by further pressing operations turning out the free edge of the rim (Figs. 19 and 20), the final form being produced by rolling and/or pressing operations. In a further form (Fig. 23) the whole rim is formed in one piece integrally with the wheel disc, and the wheel is formed in several pressing operations and a flow-turning operation.
