Abstract: 433,284. Guiding webs. JAGENBERG-WERKE AKT.-GES., 107, Himmelgeisterstrasse, D³sseldorf, Germany. Nov. 7, 1933, No. 30981. Void [Abridged as open to inspection under Sect. 91 of the Acts, May 8, 1934]. [Class 100 (i)] Webs of paper coated on one side with glue, varnish, &c. are guided and conveyed through drying or other apparatus by conveyers parallel to and laterally displaced from one another, turning-bars arranged at an angle of 45‹ with the paths of the web being provided to guide the web from one conveyer to another. In one form the conveyers comprise a pair of endless bands. In another form, Fig. 3, the web is conveyed by co-axial drying-cylinders z<1>, z<2>, z<3>, z<4> the turning-bars u<3>, v<2> between the cylinders z<2>, z<3> being in a plane at right angles to that of the bars u<1>, v<1> and u<3>, v<3> between the pairs of cylinders z<1>, z<2> and z<3>, z<4> respectively. The web passes from a reel 7 through a coating apparatus 8 and is rewound on a reel 9. In further forms, drying-cylinders are arranged in pairs on a pair of parallel shafts, the web passing from a roll to a cylinder on one shaft and over the turning - bars to an adjacent cylinder on the same shaft and thence to a cylinder on the second shaft, round turning- bars to an adjacent cylinder on that shaft and finally to a rewinding-reel.

Title: Checking variations in the diameter of a fibre
IPC: B65H63/06
Filed: 1969-06-20
Abstract: 1,254,958. Monitoring the diameter of fibres. PHILIPS ELECTRONIC AND ASSOCIATED INDUSTRIES Ltd. June 20, 1969 [June 21, 1968], No. 31246/69. Heading G1A. In a method of checking variations in the diameter of a fibre being drawn, the radiation from a source 2 is divided into two parts of which the first part intercepted by the fibre is subsequently incident on a photo-electric cell 4 connected in a circuit whose output is related to the said variations, the second part of the flux from the source bing used to derive a reference signal. As shown, radiation from a tungsten filament lamp 2 is collimated by a lens 3 and split by a halfsilvered mirror 8. The fibre 1 is passed continuously through the first beam part which is focused by an objective lens 5 on to a silicon photo-cell 4. Located in front of the photo-cell are a diaphragm 6 and a diffusing screen 11. A diaphragm 10 ensures that a constant length of the fibre is monitored. The second part of the divided beam is stopped down by an adjustable slit diaphragm 9 and falls on a second silicon photo-cell 7. The difference current i 4 -i 7  from the two photo-cells is fed to a meter M, which records the variations in this difference current. A control arrangement may be provided to stop, or modify the conditions of the fibre drawing operation. In a further embodiment, Fig. 4 (not shown) the second or reference beams, after reflection from the beam-splitter 8, is reflected parallel to the measuring beam by a plane mirror and passes through a reference fibre parallel to the first. This reference beam is focused on to a second photo-cell, and the two photo-cell signals are subtracted as before. In the embodiment shown in Fig. 5, light from a source 2 is focused on to a diaphragm 16 through an opal glass 15 and is then collinated by a lens 17. Two resultant beams are produced by a diaphragm 18 having two adjustable apertures. These beams pass through the transparent tubular fibres 1 and 1a and are focused on to a photo-cell 14. A rotating sectored disc 9 with staggered slots or a polarizing disc associated with two crossed polarizers in each of the beams is utilized so that the two radiation paths are alternately incident on the photo-cell, the AC component of whose output is amplified by an amplifier 12 and rectified by a synchronous detector 13 whose output indicates the variations in diameter of the test fibre. The DC component of the photocell output may be used to regulate the source intensity. In all the above embodiments the fibres may be contained in a liquid whose refractive index is substantially equal to that of the fibres.

As shown, the heat exchanger 2 (comprising, e.g. finned tubes 3) is disposed in known manner around the base of a cooling tower 1. The upper section of the heat exchanger may be "dry" in order to provide that only an air stream of relatively low moisture content is in contact with the internal surface of the tower so to minimize corrosion. Alternatively (Fig. 2) the water sprays 6 may extend also into this section of the heat exchanger. A thermostat 20 in the return line 5 for the cooled fluid may control closure of valves 15, 16, 17 supplying water to the spray nozzles 6, such closure taking place in downward sequence beginning with valve 15. Alternatively (Fig. 5) a plurality of the water pumps 9 are provided the arrangement being that only when all the pumps are operating are the sprays operative at the higher levels. Switching off the pumps in sequence, again preferably by a thermostat in the line 5, progressively reduces the number of sprays.

Title: Chlorine residual controlling system
IPC: G05D21/02
Filed: 1969-06-23
Abstract: 1,222,484. Automatic control of chlorination. GENERAL SIGNAL CORP. June 23, 1969 [Aug.23, 1968], No.31591/69. Heading G3R. Chlorination of water is controlled by . periodically adjusting the rate at which chlorine is added in response to measurements of the residual chlorine in the treated water. The measurement, made at 24, is compared at 27 with a reference 26 and the resulting error signal is periodically connected through a first timer 34 for a fixed time determined by a second timer 35. The error signal proportionally controls the speed of a valve motor 29 in the chlorine supply 15 by means of a controller 32 with feedback from a tachogenerator 31. Since the motor runs for a finite time the valve is opened or closed by an amount proportional to the magnitude of the error. The off time of timer 34 is set to correspond to the time required for the chlorine added at 13 to kill bacteria so that the residual measurement made at 24 relates to the previous adjustment. The apparatus includes a device 18 which maintains a constant pressure differential across chlorine valve 16 and also adjusts a further valve 19 which regulates the chlorine flow proportionately to the water flow measured at 23, but this is not described in detail. The motor control system is as described in Specification 1,182,399 (Division H2).
