Title: Measurement of noise in a communication channel
IPC: H04J1/16
Filed: 1974-05-30
Abstract: 1460513 Measuring noise in a multi-channel FDM link POST OFFICE 16 May 1975 [30 May 1974] 24013/74 Heading G1U The noise performance of a multi-channel frequency division multiplex communications link is assessed by measuring the noise present in a quiet channel whilst the other channels are carrying traffic, this being effected by tapping the link 10a, Fig. 2, so as to extract a small fraction of the total signal over all the channels carried by the link, standardizing the resulting signal by passing it through an automatic gain and attenuator stage 12, 13, 14, where it is brought to such a level that the average power in the signal equals a pre-set reference level (either -29dBm for 1800 channel links or -32dBm for 960 channel links) and then measuring 16 the noise present in the quiet channel of this standardized signal. The result may be indicated or printed 51, and a logic circuit 21 can cause a plurality of links 10a, 10b,..., to be examined automatically successively. The automatic attenuator 13, Fig. 2, is shown in more detail in Fig. 3 and operates by comparing 26 the signal emerging from a switched attenuator 22 after detection 25 with a reference level 27, and adjusting the attenuator by a counter 29 until equality is attained. A similar arrangement is also employed to measure  the noise in the quiet channel. The standardized wide band signal is passed via a second switched attenuator 31, Fig. 4, the signal present in the quiet channel is extracted by an appropriate filter 33a, 33b,..., the signal is demodulated 34, 52, 53, 37, to extract the noise per se, and then the attenuator 31 is adjusted by a counter 48 until the noise signal - which is detected 41 - is equal to a pre-set level 45, whereupon the count in the counter 48 is a measure of the ratio of the noise in the quiet channel to the total power being passed by the link.

Title: Improvements in or relating to methods and devices for mixing fluids
IPC: B01F3/08
Filed: 1957-07-29
Abstract: 872,426. Mixing liquids. KODAK Ltd. July 29, 1957 [Aug. 3, 1956; Oct. 11, 1956], No.24035/57. Class 86 A fluid is introduced into a liquid by being passed between a pair of spaced, rotating cones. The fluid is passed down a rotating hollow tube 1, at the bottom of which it is thrown outwards through ducts 4 to the space between the bases of two cones 2, 3, one of which is hollow. It is thus thrown radically outwards from between the colsely spaced periphiral edges of the cones, into the surrounding liquid. In other forms of the hollow cone the inner surface has concentric annular grooves to provide more even distribution of the fluid, or the fluid is fed into a cylindrical recess at the apex of the cone. Several distributing cones may be provided on a common axis in which case each may be fed from a separate tube, the tubes 'being either concentric or parallel within a common outer tube. Conical guide plates may be fitted outside the mixing cones so as to direct the flow of the main liquid.

Title: Improved injection moulding press
IPC: B29C45/70
Filed: 1947-09-04
Abstract: 655,558. Injection - moulding machines. DALTON & CO. PTY., Ltd., H. Sept. 4,1947, No. 24387. Convention date, Nov. 7, 1946. [Class 87 (ii)] [Also in Group XXII] An injection-moulding press for moulding plastic materials comprises a base 3, an upper cross-head 4 secured to the base by standards 5, an upper die section 6, and a lower die section 7 which is vertically reciprocable under hydraulic power from the open position shown in Fig. 1, to the closed position shown in Fig. 2. The die section 7 is secured on a base 10 which is mounted upon two spaced-apart blocks 11 which are in turn seated upon a platen 12 secured to a main ram 13 working in a pressure cylinder 14. An injection plunger 16 mounted on an injection bar 17 is received in a bore 15. The bar 17 is secured to an injection ram 18 which enters a pressure cylinder 19 within the ram 13, the cylinder 19 being open to the pressure in the cylinder 14 through an aperture 20. Packing material 18a serves to load the ram 18 frictionally so that it will not move until the pressure on ram 13 is sufficient to create an adequate seal between the die halves and retain them in closed relation during injection of the charge. Auxiliary double-acting ramrods 21 working in cylinders 23, 25, and having shoulders 27, 28, are employed for bringing the lower die-section to a position in which the dies are nearly closed, and for opening the dies on completion of moulding. In operation a powder charge 29 is placed in the bore 15 and pressure is applied to cylinders 25 causing rods 21 to rise and carry upwardly the ram 13, the platen 12, and the injection assembly. Pressure is then applied to cylinder 14 to cause the ram 13 to lift and tightly close the die-sections. On the instant that this is accomplished the pressure in the cylinder 19 overcomes the greater load per unit area on the ram 18 and moves the ram within the cylinder 19 relatively to the ram 13. The bar 17 and the plunger 16 are thus moved upwardly and the material injected into the die cavities 81, 8<SP>2</SP>. On completion of moulding, the dies are opened by release of pressure from cylinders 14, 19 and 25, and pressure is applied to the upper cylinders 23. The resultant downward movement of the rods 21 causes the shoulders 27 to engage and foce downwardly the bar 17 until it contacts platent 12, thereby retracting plunger 16, after which movement the press is returned to the position shown in Fig. 1.

Title: Method of separating solid substances or colloids from liquids

Filed: 1950-10-10
Abstract: 676,854. Purifying liquids electrolytically. METALLGES. AKT.-GES. Oct. 10, 1950 [Oct. 28, 1949; June 9, 1950], No. 24771/50. Class 41. A method of separating from liquids solid substances dispersed therein comprises causing these substances to flocculate in a clarifying vessel provided with electrodes connected to a source of electric current, the cathode being disposed substantially horizontally at the lower end of the vessel and being supplied with current at a density of about 1 to 20 amps. per square dcm., and the solid substances being transported to the surface of the liquid simultaneously or subsequently by gas bubbles produced in or introduced into the liquid. The bubbles may be produced by electrical decomposition at the cathode. The anode may be disposed at a small distance, for example 2 to 0.5 cm. above the cathode. The method may be carried out in two stages in the first of which the floes are formed by using a high current density, and in the second of which the current is reduced to form fine gas bubbles which transport the floes to the surface of the liquid. The electrodes may be perforated to allow escape of the gas bubbles. The metals which are most electropositive, for example aluminium, are more suitable as electrodes than metals, for example copper or iron, which are more electronegative. It is also advantageous to use metals which yield to the liquid to be clarified constituents similar to those which are to be separated. The method of separating, particularly where aluminium electrodes are employed, may be carried out with alternating current, in one or both stages. Air or other gases may be introduced into the clarifying vessel through a dividing device, for example a clay cell, to form very fine gas bubbles. Gases produced at the anode such as chlorine, which are not desired in the clarified liquid, may be removed from the space between the anode and surrounding diaphragm. A magnetic field may be applied to the clarifying vessel to accelerate clarification.
