Title: Improvements in or relating to the purification of palm oil
IPC: C11B3/00
Filed: 1962-08-29
Abstract: Palm oil is purified by countercurrent washing with water in the liquid phase.  The oil may be clarifed before countercurrent washing by heating e.g. to 70 DEG  to 90 DEG  C. and allowing non-oily extraneous matter to settle in a settling tank the clarified oil being drawn off from the liquid surface.  The countercurrent washing step is carried out by feeding oil droplets into the base of a column supplied with water preferably at the same temperature as the oil from an inlet near the top of the column, the column being provided with a grid e.g. a grating or perforated disc intermediate the oil and water inlets.  The grid has apertures totalling at least 40% of the cross-sectional area of the column and the water flow-rate may be adjusted to the free settling rate of the impurities contained in the oil.  The oil passes from the column to a separator in which any entrained water may settle out.

Filed: 1968-07-12
Abstract: 1,268,627. Digital transmission systems. PLESSEY TELECOMMUNICATIONS RESEARCH Ltd. 14 July, 1969 [12 July, 1968], No. 33466/68. Heading H4P. Binary data M to be transmitted in differential phase duobinary form is applied to modulo- 2 adder 2 whose other input B is the 2-bit delayed output C of the adder. The adder output C is also fed via a filter 7, having a response defined in the Specification and giving a duobinary output, to a mixer 9 and is also fed to a second modulo-2 adder 6 whose other input is a half bit-rate square-wave clock signal D. The output of adder 6 is fed to a second mixer 10 via a second filter 8. The mixers are fed by carriers 90 degrees apart and the sum S of their outputs is the signal applied to the transmission channel. Various demodulators are described as indicated below. Fig. 5: the received signal 5 is mixed at 16 with a carrier from oscillator 17. After band pass filtering the mixer output passes to mixers 19, 22. It is also fed through a 1-bit delay direct and with 90 degrees displacement to the mixers which feed low pass filters 21, 24. The modulus of the output J of filter 24 is subtracted from the output I of filter 21, the resulting signal K being gated by bit-rate clock pulses A. The gate's output controls a bi-stable 28 to develop a binary output M identical to the input of the transmitter. The clock pulses A are derived from signal K by the units 29-33 shown. Oscillator 17 is synchronized by the filtered signal J. Fig. 7 (not shown): the received signal is fed to two channels each consisting of a mixer (36, 37) fed by carriers 90 degrees apart and feeding a low pass filter (40, 41). Each filter feeds direct and via a 1-bit delay (42, 43) an arrangement of four mixers feeding adding and subtracting units (46, 49) which give respective outputs I, J. The remainder of the circuit is identical to that shown in Fig. 5 consisting of units 25-28. Fig. 8: the received signal passes to mixers fed by carriers 90 degrees apart. After filtering the mixers' outputs P(t), Q(t) are fed to a first circuit comprising differentiators 52, 53, mixers 54, 55 and subtractor 56 to develop a signal R. The outputs are also fed to a second circuit comprising squaring units 58, 59 and adder 60. The difference U of the output of the adder and the modulus of R is formed at 61 and sampled at 62 with clock pulses V. The samples control bi-stable 63 which delivers the binary output M. Fig. 10 (not shown): the received signal passes to mixers fed with 90-degree carriers as before, the filtered outputs (W, X) passing to gates where they are sampled by 90-degree displaced half bit-rate clock pulses from an oscillator controlled by the difference of the moduli of the outputs W, X. The samples control a monostable which delivers a binary signal direct and via 2-bit delay to a modulo-2 adder whose output is the demodulated binary signal. The carriers are generated by a phase-lock loop fed by outputs W and X and including, subtracters, gates, and adders.

Title: Improvements in and relating to the treatment of hides
IPC: C12N9/30
Filed: 1928-11-15
Abstract: 300,615. Le Petit, C. J. M. M. Nov. 16, 1927, [Convention date]. Enzymes.-A mould culture product for the preliminary treatment of hides and obtained by the cultivation of fungi such as aspergillus niger and penicillium glaucum according to the process of Specification 250,907. is treated with a plasmolyzing salt such as anhydrous sodium sulphate, sodium bicarbonate and magnesium sulphate capable of promoting the excretion of the enzymes from the mycelium spores or cells. The product to be treated with plasmolyzing substances consists of a damp somewhat viscous mass which is brought to the condition of a dry powder in addition to the freeing of the enzymes from its constituent cells. The dehydration effect is specially marked when mixture of anhydrous sodium sulphate, sodium bicarbonate and boric acid is employed. Dehydration may also be assisted by low temperature evaporation, preferably in vacuo. According to an example, a culture obtained by the development of aspergillus orizae is mixed with 40 to 50 per cent of anhydrous sodium sulphate and a small quantity of sodium bicarbonate and boric acid. Specification 16198/14 also is referred to. The Specification, as open to inspection -under Sect. 91 (3) (a) comprises also the use of magnesium and ammonium chlorides as plasmolyzing agents and states that the treatment with plasmolyzing; substances is applicable to the product of fermentation, in the presence of a lipase activator such as manganese sulphate, of a grain such as castor oil seed, e.g. the product of the process described in Specification 216,546, [Class 76, Leather], the fermentation liquor being evaporated and the solid matter treated with the plasmolyzing salt. This subject-matter does not appear in the Specification as accepted.

The invention comprises a method of converting a supersaturated solution of a gas in an aqueous liquid to a saturated solution wherein the liquid a sufficient amount of water is electrolytically decomposed to produce a plurality of gas bubbles rising through the liquid to liberate excess gas, and a method of determining the total amount of gas dissolved in supersaturated solution in the liquid by rendering the solution saturated as described above and measuring the temperature of the saturated solution and the pressure of free gas in equilibrium with the saturated solution in a closed vessel. In the apparatus of the Figure, which may be used for the treatment and measurement of carbon dioxide in beer, beer flows into container 3 from conduit 1 via pipe 2, and is returned to the conduit via pipe 4. Container 3 communicates via tube 8 with gas space 10, which opens to the atmosphere through outlet 11. Electrodes 14 and 15 are connected to battery 19 and switch 20. With valve 9 closed and valves 6, 7 and 12 open, beer flows continuously through container 3. Valves 6, 7 and 12 are then closed and switch 20 is closed for some seconds, whereupon gas bubbles from the electrodes rise to the surface, forming nuclei for carbon dioxide separation. The equilibrium gas pressure may be read on gauge 13 and the temperature of the saturated solution read on thermometer 21.
