Title: A device for the wet treatment and backwash of slubbing
IPC: D06B3/02
Filed: 1962-09-07
Abstract: 999,365. Treating textiles. FLEISSNER Ltd. Sept. 7, 1962 [Sept. 8, 1961], No. 34416/62. Heading D1L. In a device for improving the backwash effect in the wet treatment part of a backwasher, in at least one liquor container, there are arranged at least two guide rollers and in between every two guide rollers there is provided at least one deflecting roller which serves as a pressure roller. In the embodiment shown material 1 is introduced between pressing rollers 7, 8; over a deflecting roller 10 into bath 4 containing liquid 3. In the bath there are a number of guide rollers 2 having pressing rollers 6 in contact therewith. A deflecting roller 9 which serves also as a squeezing roller conducts the material from the one guide roller 2 to the next. The guide rollers may have a smooth surface or the surface may be perforated, liquid being drawn into or expelled from such guide rollers. The pressing rollers may also be smooth surfaced or perforated or they may be provided with uneven portions. The material passing out of bath 4 passes through squeeze rollers 7a, 8a and the liquid squeezed from the material passes via. guide means 12 into a filter 15 and thence into container 16. A circulating pump 13 conveys the liquid through pipe 18 to pipe 18a and thence into bath 4 or alternatively the pipe 18a may be connected into one of the guide rollers 2. The material may pass into a further bath 4a and there may be further baths following that. Replenishing liquid is supplied via. float 14a from flushing tank 14 which ensures the supply of the requisite amount of liquor. In an alternative arrangement the overflow edge 11 of bath 4 may be made adjustable.

Abstract: 1491468 Radiating line telecommunication systems; diode gating circuits COAL INDUSTRY (PATENTS) Ltd 20 May 1975 [7 Aug 1974] 34806/74 Headings H4L and H3P A telecommunication system, e.g. for a mine, of the kind referred to in Specification 1,485,156, comprises a base station joined to a main radiating line C, C &c. having a plurality of repeaters D, D &c. and a mobile station E, a further length of radiating line parallel to the main line being divided into sections F, F &c. substantially equivalent in length to the lengths of the main line between repeaters, or between the base station and a repeater, and switching means G adapted to connect different sections of the further line to lengths of the main line, whereby the variation of signal strength along the line may be reduced. In the embodiment, A is a transmitter and B a receiver, the repeaters D being unidirectional. The sections F may all be connected to the output of a repeater (with the last section connected adjacent to B), and then variations of signals transmitted from A are reduced. With the switches G in the alternative position signals transmitted from E to B are similarly affected. Preferably the switches G are operated at a frequency of at least 3 kHz so that signals in either direction are affected alternately. The arrangement also reduces signal strength variations along the line due to standing-waves or multipath propagation. Each switch G may comprise a pair of diodes (H, J), Fig. 2 (not shown), connected in parallel with opposed polarity, R.F. chokes (K, L), and capacitors (M, N) connected respectively to the input and output of the repeater, the switches being controlled by an alternating current along the further line F, F &c. When line F, F goes positive (J) conducts and the further line is connected, for R.F., to the repeater output via capacitor (N); conversely when line F, F goes negative (H) conducts and the R.F. path is through (M).

A three-phase, squirrel-cage motor having pole-changing by pole-amplitude modulation is arranged to run at intermediate speeds by differentially energizing the motor windings in the pattern appropriate for both polenumbers simultaneously, i.e. varying the applied voltages in a simultaneously opposite manner to produce the speed required. The windings may be as described in Specification 926,101 or 900,600 in which, in one mode the windings are each energized between their ends 11, 12; 11<SP>1</SP>, 121; and 11<SP>11</SP>, 12<SP>11</SP> respectively, and in the other mode between these ends joined together and through an additional winding connected to a centre-tap 13, 131, 1311. The two modes of energization are provided by a differential voltage regulator 20 which may be of various types, e.g. an induction regulator as shown. The tapping-points 14, 141, 1411 are energized directly from the regulator to give parallel-star operation. The other mode of connection, which is effectively a series star or delta connection, is achieved through a transformer 40 having primary windings 41, 42, 43 and secondary windings 51, 52; 53, 54; 55, 56 connected across the motor windings.

Title: Improvements in and relating to granular fertilizers based on urea
Inventor: PARMELLA RALPH
IPC: C05C9/00
Filed: 1956-11-21
Abstract: A process for the production of urea based granular fertilizers having a nitrogen content in the range 30% to 46% by weight comprises charging a granulating device with substantially dry material comprising urea and a filler selected from calcined calcium sulphate and kieselguhr, mixtures of these or mixtures of at least one of these with ground limestone and, while continuing the granulation, simultaneously introducing into the granulator a concentrated aqueous solution of urea, and drying the granules produced at a temperature not exceeding 100 DEG C.  The expression "calcined calcium sulphate" includes calcium sulphate hemihydrate soluble anhydrite and any intermediate hydrated calcium sulphate but not insoluble anhydrite. Various granulators may be used, e.g. drum granulators and ribbon mixers but preferably paddle mixers or granulators; it is also desirable to provide the granulator with heating means e.g. a steam jacket. The dry material in the initial mixture may comprise crushed over-size and fines drained from a previous operation.  Suitable fillers for granular products of the invention having a nitrogen content of 40 to 46% are calcined calcium sulphate or kieselguhr or mixtures of these and for those with nitrogen contents of from 30 to 40% a filler comprising a major proportion of limestone. The moisture content of the granules during drying is reduced to 1% or less, and the drying is preferably carried out in a countercurrent stream of hot gasses.  Specifications 624,642 and 717,195 are referred to.
