Title: Dicarbonyl treatment
IPC: B01J13/10
Filed: 1959-11-18
Abstract: Membranes formed by the coacervation of material comprising at least one gelable hydrophilic colloid having amino groups and peptide linkages (e.g. proteins and polyamines) are treated with a solution of a dicarbonyl compound of general formula R1-CO-CO-R2, wherein R1 and R2 are hydrogen atoms or methyl or ethyl radicals.  The membranes may be formed by simple or complex coacervation of one or more of the above colloids by any process on to particles which may be solid, oil, hydrophilic liquid-in-oil or oil-in-hydrophilic liquid emulsions and which may comprise "active" ingredients which render the preparations suitable for use as fertilizers, plant growth hormone preparations, bactericides, pesticides, vitamin preparations, medicines and food additives.  Treatment is preferably carried out after gelling (e.g. by cooling) of the coacervate by addition of a solution of the dicarbonyl compound in water or some other solvent, e.g. ethanol, acetone, dioxane or chloroform, to the coacervate in the spent coacervating medium. Specified colloids are gelatine, fibrinogen, polylysine and polyornithine.  Specific examples relate to (a) the treatment of aqueous urea solution-in-corn oil emulsion (in gelatine) with glyoxal; (b) aqueous sulphanilamide-in-lanolin emulsion (in fibrinogen) with 2,3-butanedione (these capsules being stated to be suitable for incorporation into an ointment); (c) ethanolic "chlordan" (insecticide)-in-peanut oil emulsion (in gelatine) with 3,4-hexanedione; (d) aqueous chloral hydrate-in-mineral oil emulsion (in gelatine/styrene maleic anhydride copolymer complex-coacervate) with glyoxal; (e) glyceryl monostearate coated calcium carbonate (in gelatine) with glyoxal, 2-oxopropionaldehyde, 2,3 - butanedione, 2,3 - pentanedione, and 3,4-hexanedione.  Specifications 444,389, 751,600, 911,483, 929,401, 929,402, 929,403, 929,408 and 929,409 are referred to.

Title: Apparatus for washing casks
Inventor: HARGREAVES GEORGE
IPC: B08B9/08
Filed: 1961-11-09
Abstract: 1,030,692. Washing casks. WRIGHT HARGREAVES ENGINEERING CO. Ltd. Jan. 17, 1963 [Nov. 9, 1961], No. 40124/61. Heading B8T. Apparatus for washing casks comprises a nozzle 20 mounted for upward movement to project into the bung hole of a cask 12 and for subsequent downward retraction, there being centralizing means for correctly locating the cask over the nozzle, the centralizing means comprising two pairs of arms 16, each pair being set in V-formation so as tangentially to contact the cylindrical wall of the cask, and control means for projecting and retracting the nozzle and for automatically causing a valve 32 controlling flow of washing liquid to the nozzle to open when the nozzle is fully projected and to close when the nozzle is retracted. In the embodiment shown a cask 12 is carried to a position above the nozzle 20 by an intermittently driven conveyer, and is centralized by the arms 16 being swung inwards by bell-cranks 14. The nozzle 20 is mounted on a telescopic pipe 21, 22 and is projected into the cask by the swinging of an arm 23 about a pivot 30 under the action of a ram 29. As the arm swings to fully project the nozzle its other end 27 depresses a plunger 33, thus opening the valve 32 in a supply pipe and hence allowing water or other washing liquid to reach the nozzle, where it is distributed by a rose 34 having obliquely inclined holes. The nozzle 20 is rotatably mounted on the pipe 22 and as water is forced from the rose it rotates to direct water against the entire inner surface of the cask. The nozzle may also be adapted to reciprocate vertically during the washing period. After a predetermined time the nozzle is withdrawn and the valve 32 closes under spring action to cut off the water supply. A device is included between the arms 16, which cuts off the air supply to the ram 29 if no cask is present, and so prevents projection of the nozzle. A single washing station or a number of washing stations may be arranged to operate.

Title: Electronic three-phase four-wire system watt-hour meter
IPC: G01R21/133
Filed: 1975-10-07
Abstract: 1491290 Energy measuring OSAKI ELECTRIC CO Ltd 7 Oct 1975 40953/75 Heading G1U [Also in Division G4] In a poly-phase watt-hour meter, voltage and current measurements for the individual phases are made cyclically, each pair of voltage and current measurements are multiplied, and the resulting products are summed to provide a measure of the instantaneous power, which is then integrated, with respect to time, over the period for which measurement of the total energy is required. Cyclical sampling of the individual phases can either be at a frequency asynchronous with, and considerably higher than, the supply frequency - as in a first embodiment Fig. 2 which employs amplitude and duration modulation of pulses to effect multiplication - or the sampling can be synchronized with, and at, the supply frequency - as in a second embodiment Fig. 6 which employs sums of quarter-squares to effect multiplication. In the first embodiment each negative-going edge of a sampling pulse Q, Fig. 2, causes a sequencer B cyclically to mark one of three leads bl, b2, b3 to open a corresponding pair of voltage and current switches S1, S1'; S2, S2'; S3, S3'; for the three phases of a supply 123N. Each lead b1, b2, b3, when marked, for example lead bl, which closes switches S1, S1' as shown, remains marked for a duration linearly proportional to the phase voltage e at that instant, this being achieved by comparing D the phase voltage e with a linearly rising voltage produced by charging a capacitor Co at a constant rate from a constant current source Tr2. When the voltage across the capacitor Co has risen to the phase voltage e (plus a small bias Ea), the PUT comparator D fires to raise the input to the sequencer B which then terminates the marking on lead b1 and the switches S1 and S1' open. Thus, the current sensing switch S1' will have been open for a duration linearly dependent upon the corresponding phase voltage, so that the pulse that passes to a summing capacitor C4 represents, by its area, the instantaneous power in the phase being sensed. Successive power representing pulses are summed, and the result is converted to a corresponding frequency, the cycles of which are counted F. A modified duration modulation circuit Fig. 5 (not shown), is described. In the second embodiment Fig. 6 the sequencer B is advanced by pulses Q derived from one of the supply phases. When one of the leads b1, b2, b3 is marked, for example bl, in the first half-cycle a voltage e + iR, where e is the phase-voltage, i is the phase-current, and R is the resistance of each of the resistors rl, r2, is applied to the base of a squaring circuit Tr7, and during the second halfcycle the voltage e - iR is applied to the squaring circuit. The result is that currents proportional to + (e + iR)<SP>2</SP> and to - (e - iR)<SP>2</SP> are applied successively to a summing capacitor C5, to produce frequency significant pulses as before.
