Title: Improvements in or relating to methods of filtering and filtering apparatus
IPC: B01D37/02
Filed: 1961-05-17
Abstract: 908,879. Feeding filter aid. ETABLISSEMENTS G. PEPIN FILS AINE ET SOC. DU FILTRE GASQUET, and BERRY, G. May 17, 1961 [Nov. 7, 1960], No. 18035/61. Class 46. To form a bed on a filter (not shown)- beyond a point 25 in a flow line 30, diatomaceous earth is deposited in a reservoir I and made into a suspension by pre-filt admitted at 2, 34. Then a valve 1 is partly or wholly closed and a valve 3 is opened, valve 2 remaining open, to feed the suspension to the filter. Meanwhile a suspension of diatomaceous earth is being formed in a reservoir II, and after formation is continuously circulated through a pump 21 by withdrawal at 37 and re-introduction at 39. When the bed formed on the filter is complete, cocks 2 and 3 are closed and cock 1 opened appropriately. A valve 9 is provided to permit the pump 21 (which has'a constant output) to feed intermittently a proportion of diatomaceous earth slurry into the flow line at b. The valve 9 is operated electrically by a circuit 9a including a contact breaker 26. 'The contact breaker is operated in turn by an adjustable rotary cam 15, and the cam is adjusted to provide the desired ratio of valve-open period to valve-closed period. The cam motor is then switched on so that some suspension is fed intermittently from reservoir II to the flow line, the remaining portion of the pump output being returned to reservoir II via pipe 39 and valve 8 to keep the suspension stirred. When reservoir II is empty it is replaced by reservoir I which has meanwhile been replenished. Downstream of the filter is a pump (not shown). The pressure in the reservoirs is constrained to vary directly with the liquid pressure in the flow line by a valve 23 which feeds gas from a cylinder 22 to either reservoir as appropriate (through 42 or 43) and which is controlled by pipe 44 connected to the flow line.

Abstract: 546,052. Treating textiles with liquids. COURTAULDS, Ltd., and McFARLANE, R. A. Dec. 24, 1940, No. 18095. [Class 15 (ii)] Woven material suitable for use as bolting cloth, grit gauze or the like is obtained by weaving, in a plain weave, artificial thread containing one or more continuous filaments, and treating the material with a solution of an artificial resin which has no appreciable swelling effect on the filaments, is not sticky or tacky at or below 50C., and is free from volatile plasticizer, so as to cause the warp and weft threads to adhere at their crossings, whereby they are prevented from slipping over one another. Regenerated cellulose, cellulose derivative, and artificial resin threads may be used. In order to avoid any closing of the interstices of the fabric by a film of lacquer, the fabric while still wet with the lacquer may be passed over a rod or series of rods. In an example, a viscose rayon fabric, woven with a plain weave is padded with a solution in ethylene glycol mono ethyl ether, benzol and alcohol of a phthalic anhydride-castor oilglycerol resin. The fabric is dried at 70C. on a stenter frame, padded again with the same solution, dried and heated on a stenter frame for a few minutes at 110C. The fabric has a smooth stiff handle and may be used as a sieve. Specifications 280,989, [Class 15 (ii)], 366,718, 388,157, 397,711, 450,764, and 466,178, are referred to.

Title: Improvements in or relating to automatic telephone exchange equipment
IPC: H04Q11/04
Filed: 1946-06-20
Abstract: 613,617. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., and RANSOM, D. H. June 20, 1946, No. 18558. [Class 40 (iv)] [Also in Group XL (c)] In a system in which subscribers' lines terminate on the electrodes of a cathode beam distributer which provides a number of communication channels in the form of interleaved pulses, upon a call being made a "pulse line finder " is appropriated by the call and serves to open a communication " gate " for the pulses of the calling line. The distributer 2 feeds an amplifier 3 which delivers positive calling pulses, preferably clipped to uniform amplitude, over 21 to a common inverter 4, and communication pulses over 20 to a number of gates 11. The common inverter normally passes the calling pulses unchanged to the line finders in parallel. Each of these comprises an inverter 6 which normally inverts by virtue of the input transformer 36 and delivers negative pulses to a gate circuit 9 which receives also positive pulses from a generator 8 at a frequency differing slightly from the scanning frequency of the distributer 2. When two incoming pulses coincide, gating pulses are emitted through the output transformer 48 to lock the generator in synchronism with the calling pulses. The line finder is thus appropriated by the call, and the gating pulses are fed also over 49 to open the corresponding communication gate 11 and to cause the common inverter 4 and finder inverter 6 to reverse their normal operations, so that the finders now receive negative pulses which are effective only in the seized finder where the gate circuit 9 receives negative pulses as before. The communication pulses, which are modulated first with dialling signals and then with speech and may be clipped to give the effect of 100 per cent modulation, pass through a demodulator 12, e.g. a low-pass filter, to selection circuits which serve to impose an appropriate timedelay on the modulated pulses and apply them to the control grid of the distributer to modulate the beam at the instants when it is scanning the electrode of the called line. The called party is given a calling signal, and when he replies pulses at the time-position of his line are applied over 14 to cause the common inverter 4 to invert the pulses arising from his line in order to nullify their effect on the finders. The apparatus is restored when the calling pulses cease. Valve circuits. The inverting and gating circuits 4, 6, 9, 11 each comprise a pentode 23 normally biassed to cut-off and having connected across its suppressor grid and cathode a diode 26 which becomes a short-circuit when it is rendered conducting by a positive pulse over 29. If at the same time an incoming positive pulse over 21 appears on the control grid, a negative pulse is produced at the anode. In the case of the inverters 4, 6, incoming positive pulses pass directly to the anode through a network 24, 25, and the negative pulses produced when the suppressor grid is opened up are of sufficient amplitude to overcome the direct positive pulses.
