Title: Fungicidal compositions
IPC: A01N59/20
Filed: 1936-12-16
Abstract: Dispersible fungicidal pastes or powders containing cuprous oxide are prepared by incorporating a water-soluble dispersing agent with previously prepared cuprous oxide.  Preferred dispersing agents are the substances known under the Registered Trade Marks "Goulac" and "Dispersol"; these are used in the proportions of 2 to 35 per cent for a paste, and 30 to 60 per cent for a powder.  Adhesion promoters such as linseed oil, rosin oil, stearic acid or oleic acid may be added in amounts up to 5 per cent, and when these are added the proportion of dispersing agent may be materially reduced, for instance to 0,1 to 1,0 per cent.  The dispersing agents are stated to prevent or retard oxidation of the cuprous oxide, particularly when this is in the yellow or orange coloured form.  The cuprous oxide may be prepared by adding caustic alkali to a slightly acid solution of sodium chloride and copper chloride or sulphate which has been treated with metallic copper at raised temperature, or to a solution of euprous chloride prepared from metallic copper and chlorine.  The precipitate obtained is washed and filtered, the filter cake ground with the dispersing agent in a ball mill, and, if required, the product is dried.ALSO:Fungicidal compositions are prepared by incorporating a water-soluble dispersing agent with previously prepared cuprous oxide at ordinary or slightly elevated temperature.

Title: Apparatus for Controlling a Work Performing Device such as Flying Shear
Inventor: STUART ROBERT MALCOLM
IPC: B23D36/00
Filed: 1965-08-13
Abstract: 1,151,506. Controlling flying shears. ENGLISH ELECTRIC CO. Ltd. 12 Aug., 1966 [13 Aug., 1965], No.34862/65. Heading B3W. An apparatus for controlling a flying shear 2 comprises a detecting means 3 to detect the arrival of the leading edge of the work material 1 at position A and for initiating operation of the flying shear 2 before the material reaches the position C, the said operation activating a trigger 7 to start a calibration count by a counter 11 of the distance BC, and a second counter 16 for progressively counting the passage of predetermined lengths of material past the position A. The stock material 1 is advanced towards the shears 2 and reaches the position A where the photocell 3 detects it and applies a continuous output to the AND circuit 4 and the trigger 5. A pulse generator is associated with each mill stand S7-S10, one of which is connected through the switch 15 to the AND circuit 4. The output from the trigger 5 is fed to the gating circuit 7 and to the OR circuit 6, whereupon the shear 2 is accelerated to effect a " calibration cut." The count in a gating circuit 21, preselected by an operator by means of the knobs 22 through gear-box 23 and binary digitizer 24 is simultaneously fed to the counter 16. The limit switch 8 is momentarily closed to apply a pulse through the gate 7 to the trigger 9, and the AND circuit 13 and consequently a progressively increasing count is entered into the counter 11 from the pulse generator associated with the mill stand S8. As the material 1 is fed past the position A, the count in the counter 16 is progressively decreased and an increasing count entered into the counter 11. When the leading edge of the material reaches position C, a continuous signal is applied to the gate 10 from a photo-cell 19 resulting in a stopping of the count of the counter 11, i.e. " the calibration count " equivalent to the distance BC. The count in the counter 16 continues to decrease as the strip passes between the shear until it reaches zero, whereupon a continuous pulse is applied to the AND circuit 17, the NOT circuit 18 and the OR circuit 12 to the AND circuit 13 resulting in the count of the counter 11 being progressively decreased to zero whereupon a continuous output is applied through the AND circuit 17 to the OR circuit 6 to cause the shear 2 to accelerate and cut the material. The signal which initiates this cut is also fed through the trigger 20 to the gate 21 and the preselected count is again entered in the counter 16. The counter 11 is thereafter held at zero since both photo-cells 3, 19 are continuously activated. The cut length setting is determined by the operator on manual movement of the knob 22 and the switch 15 is ganged to the switch 26 so that the indicator 31 gives a correct reading for the various diameter rolls in the mills S7-S8.

Title: Improvements relating to electric pulse counting circuits
Inventor: SIMMONS BRIAN DESMOND
IPC: H03K21/00
Filed: 1959-10-16
Abstract: 923,327. Electronic counting - apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 29, 1960 [Oct. 16, 1959], No. 35134/59. Class 106 (1). A pulse counter for counting a series of input pulses separated by time intervals that are each an integral multiple of a basic interval greater than one, comprises one or more counting stages, each including a delay line store having a circulation time which is an integral multiple of the basic interval and a carry gate adapted when actuated to control the erasure of any pulses circulating in the store or stores and to supply a pulse to a further delay line connected back to the counter input, the delay time of the further delay line being so chosen that this pulse arrives at the counter input at a time within the basic interval of separation of the input pulses of said series being so counted. As shown, Fig. 1, a counter similar to that described in Specification 923,326 is provided with a delay line DT connected between the output of a carry gate G3 and the input to the counter. The counter is used with a hundred-channel time division multiplex system having a cycle period of 100Ás. Each channel is itself shared on a time division basis achieved under the control of nine time-staggered timing pulse trains such as PP1, each having a 9Ás period. Thus coincidence between a timing pulse of a particular train and a particular channel occurs only once every 900Ás. The counter comprises three stages, each including a delay line store DADC having a circulation time of 900Ás and input pulses in time positions defined by the train PP1 applied at I are counted in the three counter stages, as described in Specification 923,326. When the gate G3 produces a carry, however, a pulse is fed to the delay line DT which has a delay of 100Ás so that the pulse is entered at the input I<SP>1</SP> in a channel period of the same channel but in a different time position, as defined by the timing pulse train PP2. Further carries may be catered for by the remaining timing pulse trains. An embodiment employing only one delay line storage counting stage is described (Fig. 2, not shown).
