Title: Improvements in and relating to the biological water-retting of flax and other fibrous plants
Inventor: RHODES LEOFRIC JOHN
IPC: D01C1/04
Filed: 1955-06-02
Abstract: Retting liquor, which has been used for retting flax or other fibrous plants, is rendered suitable for use in a further retting operation by subjecting it to aeration whilst in admixture with activated sludge.  During retting, volatile fatty acids (e.g. acetic acid) are formed in the liquor and these act as inhibitors of the retting process.  However, these acids are destroyed during the aeration. The activated sludge may be produced by the aeration of used retting liquor, provided the volatile fatty acid content thereof is sufficiently low and, if necessary, the used liquor may be diluted, or subjected to a preliminary aeration, to bring the volatile fatty acid content to the desired low level. But the bacteria which produce the sludge become progressively tolerant of greater amounts of the acid, so that the volatile fatty acid content of the liquor may be gradually increased to the maximum concentration in which the bacteria can remain active.  Diffused aeration may be employed in the preliminary aeration step, while the aeration in the presence of activated sludge may be effected with brush aerators which may be carried by rafts floating on the liquor.  The sludge in the reconditioned liquor may be allowed to settle before the liquor is used in a further retting operation, but the settling period may be limited so that a predetermined quantity of sludge remains in suspension and thus passes to the retting tanks.

Title: Improvements in or relating to gas discharge tube counting arrangements
Inventor: MULLARKEY ALFRED JOHN
IPC: H03K23/82
Filed: 1948-06-11
Abstract: 696,543. Counting-apparatus. STANDARD TELEPHONES & CABLES, , Ltd. June 11, 1948, No. 15812/48. Class 106 (i). [Also in Groups XXX and XL (c)] A pulse counting circuit comprises a train of gas discharge tubes which discharge in sequence in response to applied pulses, the firing of a given tube extinguishing the discharge in a preceding tube and means whereby a discharge can be caused to travel along the train of tubes in either direction. Fig. 1 shows a pulse counting circuit in which if tube 1a is initially discharging tube 2a is primed via circuit 11 so that the next pulse applied at lead 5 fires tube 2a and thus primes tube 3a. Subsequent pulses on lead 5 cause the a tubes to fire in a clockwise sequence. When, however, tube 1a is discharging tube 3b is also primed so that a pulse applied to lead 7 causes this tube to fire and subsequent pulses cause the b tubes to fire in anticlockwise sequence. The firing of any given tube causes a voltage drop in the common anode load resistor 10 and thus extinguishes the preceding tube in the chain. Thus, by inspection the difference between the number of pulses applied to leads 5 and 7 can be determined and the equality of these numbers which is evidenced by the home position tube 1a firing can be indicated. In a modification, Fig. 2 (not shown), four electrode cold cathode tubes are used, thus combining each pair of the associated 1a and b tubes in a single envelope. The handling capacity of the system may be increased by connecting a number of counting rings in parallel so that they are simultaneously actuated by the two pulse trains, Fig. 3 (not shown). The circuit may be used as an axle counter in a railway signalling system a pulse is then applied to one lead each time an axle enters a signalling section and a pulse is applied to the other lead each time an axle leaves a section (see Group XXX). Specifications 567,863, 613,137, [Group XL (b)], 691,901 and 696,642, [Group XXX], are referred to.

Title: Improvements in means for central lubrication
IPC: F16N29/00
Filed: 1937-06-08
Abstract: 495,975. Lubricating. LAINGLEY, T. W., and TECALEMIT, Ltd. June 8, 1937, No. 15815. [Class 12 (iii)] A lubricant fitting, tc enable lubricant from an existing lubricant system, in which the pressure may vary, to be used for auxiliary bearings, is provided with a variable resistance leakage to a delivery port or ports, the leakage means being responsive to variation of the lubricant supply pressure such that the resistance increases as the lubricant pressure increases and vice versa. As shown, the device 1 has an inlet 5, an outlet 4, and bores 8, 9, of different sizes. A hollow plunger 12 has a clearance fit in the bore 8 and carries a washer 14 and sealing ring 16, fitting the larger bore 9. Below the sealing ring 16 is a hollow tube 15, gauze disc 17, and felt pad 18. A spring 21 presses against the plunger 12 and a duct 11 makes connection between the outlet 4 and the annular space 20 between the plunger 12 and the bore 9. Oil entering at 5 passes through the plunger 12 and then between the latter and the bore 8 to the space 20 and so to the outlet. As the oil pressure increases the spring contracts and increases the length of the leakage path. At the same time the space 20 diminishes and increases the delivery pressure. The plunger 12 may be made of a material having a coefficient of expansion higher than that of the body 1 so that the leakage clearance is reduced as the lubricant temperature increases.

Title: Improvements in or relating to etherified resins
Inventor: HOWE BRIAN RUSSELL
IPC: C08G8/28
Filed: 1954-06-09
Abstract: Novolak resins modified by reaction with unsaturated hydrocarbons, e.g. styrene, as described in Specification 750,286, are etherified in known manner, e.g. by reaction with an organic derivative of a strong acid used in an alkaline medium, e.g. methyl and ethyl sulphates, benzyl chloride, allyl chloride and methallyl chloride, in an inert solvent, e.g. methyl isobutyl ketone.  Other methods for etherifying the resin are by reaction with diazoalkane, and by treatment with an alkali metal alkoxide dissolved in the appropriate alcohol.  In examples: (1) 100 parts phenol, 60 parts 40 per cent formalin and 0.6 parts oxalic acid are reacted under reflux; 500 parts of the novolak resin thus obtained are mixed with 500 parts styrene and the mixture distilled azeotropically to remove traces of water; 0.5 parts of a boron trifluoride/acetic acid complex are added and the temperature allowed to rise to 200 DEG  C. and maintained for an hour; 200 parts of this styrenated resin were dissolved in methyl isobutyl ketone at 60 DEG  C., and 231 parts diethyl sulphate, 3 parts water and 8 parts NaOH pellets added; four further additions of pellets are made at intervals of 20 minutes.  The product was refluxed, xylol added and the suspended salts removed by filtration; the filtrate was then distilled to yield a brown resin soluble in butanol, xylol and raw wood oil.  Example (2) is similar benzyl chloride being used as etherifying agent.  In Example (3) the novolak resin is modified with cyclopentadiene. Other unsaturated compounds which may be used for modifying the novolak resin are propene, isobutene, methyl cyclopentadiene and their dimers and trimers. British Specification 615,488, and German Specifications 668,952 and 673,828 also are referred to.

Title: Improved arrangement of valves for use in controlling pipes or conduits in cyclical operations such as those of adsorption apparatus for the separation of gases
IPC: B01D53/04
Filed: 1937-06-10
Abstract: The number of valves required in an installation comprising three or four adsorbers is reduced by means of the scheme shown from the customary five per adsorber to six for the complete plant.  Rotary plug valves are used, each having as many ports as there are adsorbers, and an axial passage.  The full lines <PICT:0481350/III/1> represent pipes for gaseous mixture before or after treatment; the dotted lines, pipes for desorption steam, or mixture of steam and recovered product; and the chain lines pipes for drying-fluid; fine lines indicate closed pipes, heavy lines indicate open pipes. The cycle of operations is carried out by rotating the valves H1-H3, B1-B3 intermittently through 120 DEG , as shown by the arrows; if there were four adsorbers the angle would be 90 DEG .  The gaseous mixture to be treated enters by the axial passage of one of the valves and passes thence by one of the lateral passages to the adsorber in use.  The valves may be driven by an explosion engine supplied by a constant fraction of the mixture to be treated so that the duration of the cycles is automatically adapted to the nature or quantity of the gas; or a disc having electrical contacts and actuated by a gas meter may be used.  The cocks are coupled in pairs, H1, B1, &c., each of which controls the inlet and outlet of one and the same fluid.  A single heat-exchanger or thermic battery common to all the adsorbers may be used.  After treatment the gas from the adsorber enters laterally the valve coupled to the previously-mentioned valve and passes out by the axial passage.
