Abstract: 259,732. Pollak, J. E., (Owens Bottle Co ). Sept. 8, 1925. Delivering molten metal.- A feeder of the kind described in Specification 175,949 has the plunger reciprocated by a lever, and means are provided for shifting the fulcrum of the lever in order to vary the length of the stroke of the plunger, the adjustment being made while the feeder is in operation. The apparatus comprises a , forehearth 21, Figs. 1 and 2, having a discharge orifice 23 at its outer end, a plunger 24 reciprocated vertically over the orifice, and shears 25 which are operated in timed relation to the movements of the plunger by an air cylinder. The shearing- mechanism is carried by a bracket which is pivoted at 119 to the frame of the forehearth and can be swung downwards for adjustment and repairs. The plunger is actuated by a cam 28 on a driving- shaft 29 operating through a lever 30 which swings about a fulcrum 31. The plunger is connected with the forward end of the lever 30 by a screw 39 which may be turned by means of a handwheel 42 to raise or lower the plunger with respect to the orifice 23. The fulcrum 31 may be adjusted lengthways of the lever by means of a handwheel 62. By turning the handwheel, the length of stroke of the plunger can be increased or decreased to vary the shape of the charges extruded through the orifice 23. The plunger is also rotated continuously by means of a chain 69, driven from the shaft 29, to keep the glass surrounding the plunger in suitable condition. The feeder is driven from the forming-machine by means of chains 65, 68, Fig. 2, through the intermediary of a timing-device 66. This device consists of two differential gears which also operate the valve controlling the supply of air for actuating the shearing-mechanism. By turning the idler pinions of the gears, by means of hand wheels 96, 97, the movements of the plunger and of the shears can be advanced or retarded in respect to one another and to the movements of the forming-machine.

Title: Improvements in or relating to the preparation of ceramic pastes
Filed: 1950-09-15
Abstract: Clay is disintegrated in the presence of water in a disc mill comprising a rotating disc mounted in a housing, the disc carrying at its centre blades or scoops between which the clay is fed from a hopper outside the housing.  The blades force the clay into an active zone comprised of ribs or teeth on the periphery of the disc which co-operate with stationary ribs on the inside of the housing or on another disc attached thereto.  Both sets of ribs extend radially with respect to the disc or discs.  The disintegrated clay is finally discharged at the periphery of the disc, passing to a mixing machine where fillers are added to the clay slip.ALSO:Binding clay is mechanically disintegrated in an amount of water not exceeding that required to give the desired consistency to a paste resulting from the addition of a filler thereto, to form a clay slip, and the filler added.  A preferred apparatus comprises a high speed disc mill having a zone of substantially radial teeth.  The amount of clay is determined by an automatic weighing machine and the water adjusted correspondingly and both are fed to the disintegrator.  From thence the slip may pass to a storage tank in which it is agitated, and drawn off when required for addition of the filler in a mixer.  The disintegrator can supply several storage tanks or mixers.  A preferred mixer comprises a rotating bowl with rake like tools eccentrically mounted therein and rotating counter to the bowl itself. Specified fillers are fireclay, silicon carbide, corundum or grog, whilst feldspar may also be present.

Abstract: 461,503. Separating coal. APPLEYARD, K. C., POLLITT, S. D., and BIRTLEY CO., Ltd. Aug. 13, 1935, No. 22834. [Class 72] In the separating of coal as described in Specification 421,401, a plurality of coal separating paths in one or more machines operate through the agency of a single electric discharge tube. The discriminating fingers 5-9 in the form of resilient contacts, one pair of fingers for each path, are connected at one side to earth and at the other side to one set of slip rings 33 mounted on a shaft 32 on which is also mounted to two five-part commutators and a second set of slip rings 33, the rings 33 being connected to the commutator 10, and the rings 34 to the commutator 11. The commutators 10, 11 are provided with co-operating brushes 22-26 and 27-31 respectively, the brushes 27-31 being con. nected to the anode 2 of the valve 1, and the brushes 22-26 to the grid 3 of the valve. The brushes 27-31 are also connected to relay switches 35-39 which when actuated energize solenoids 40-44 which operate doors 45-49 for the passage of one of the separated materials, e.g. stone. The relays also control hold-on circuits by means of switches 60- 64 mechanically connected to the switches 35-39 so that the circuits remain closed for a longer period than is provided by the action of the valve. The power for operating the solenoids is a source of alternating current 50 of high voltage and the power for the relays from a battery 51 or a motor generator of suitable voltage by 100-800 volts. The relay coils 53-57, which may have resistancecapacity circuits 52 connected in parallel are connected at one end to the positive end of the battery through door limit switches 65 69, and at the other end to the slip rings 34 and also via auxiliary switches 60-64 and a rheostat 58 to the battery 51. In place of the switches 65-69 which open and break the circuits when the doors 45-49 are fully open, switches may be mounted inside the doors so that the passage of the pieces of the separated material breaks the circuits. The cathode 4 of the valve 1 is heated by a step-down transformer winding 59 for the current source 50. Specification 461,504, [Group XXXVIII], is referred to.

IPC: C25D5/00
Filed: 1921-08-29
Abstract: 193,881. Hybinette, N. V. Aug. 29, 1921. Nickel, depositing; diaphragms; electrolytes, circulating, purifying, and regenerating.-In a process for depositing nickel in which there is a flow of electrolyte from the cathode chamber to the anode chamber through a filtering diaphragm, electrolyte containing free sulphuric acid is supplied to the cathode chamber, the current density, rate of flow and the nature of the diaphragm being such that the electrolyte is rendered nearly neutral in the neighbourhood of the cathode. In an example the electrolyte of nickel sulphate containing 50 gms. of nickel and 2 gms. of free sulphuric acid per litre is supplied at a temperature of 50‹ u; the excess pressure in the cathode chamber is ¢ inch to 1 inch producing a flow of about 1 litre' per sq. ft. per hour. With a current density of 10 amps. per sq. ft., the acidity of the electrolyte near the cathode is reduced to about 0.2 gms. per litre. Electrolyte is supplied to the cathode chamber B of the plating cell from a receptacle C and flows through the diaphragm d cf heavy cotton cloth to the anode chamber A. The anolyte may be removed from the top of the chamber by a pipe g and also from the bottom by a syphon h. The latter part contains more copper and may be treated separately or both may be passed to a tank D where copper is cemented out on nickel. The solution passes next to a tank E where iron is precipitated by nickel oxide the solution being thereby neutralized, after which dt is acidified by electrolysis with insoluble anodes in a tank F and returned to the receptacle C. The circulation is effected by a pump H. The process may be. used for depositing nickel from an electrolyte in which nickel carbonate is continuously dissolved using insoluble anodes. Copper nickel anodes are preferably prepared in the following way. Copper nickel matte is roasted and leached to reduce the copper content to 1 part to 3 or 4 parts of nickel; it is then mixed with 10 per cent of powdered coke and heated in an electric furnace with a flux which removes part of the iron. Specification 25122/05 is referred to.

Abstract: 1362156 Recording apparatus FURUNO ELECTRIC CO Ltd 16 May 1973 [12 July 1972 30 Dec 1972] 23408/73 Heading G1J A digitally controlled recorder comprises a clock pulse generator 1 which supplies a train of pulses to drive a pulse motor 2 for moving at least one recording pen 3, a counting circuit 4 for counting the pulses, at least one coincidence circuit 6 which, when the count output of the counting circuit 4 coincides in value with a digital input from a measuring apparatus 7, supplies an output to the pen 3 to effect a record, and means 5 for detecting a predetermined reference position of the pen 3 which defines a start point of the recording range, and producing an output which resets the counting circuit 4 when the pen reaches the reference position. The pen 3, which is resiliently supported on a nut 25, forms an electrode for use with a discharge destruction or electrolytic type of recording paper. The paper 24 is drawn steadily from a roll 21. The motor 2 drives the nut 25 via gears 29, 28 and a lead screw 27, contact switches 5, 17 sensing the presence of the nut at the start and end limits of its travel. The pen 3 makes a plotting sweep from right to left (Fig. 3) across the paper 24, friction between the nut 25 and lead screw 27 pressing the pen on the paper. On the return sweep, this friction lifts the pen clear of the paper. Bars 30, 31 limit the pivotal movement of the nut 25.  As the pen reaches its start position, the switch 5 is closed to send a reset signal to the counter circuit 4 and a signal to turn the Q side of a flipflop 15 to HIGH level to close a gate 12, stopping the motor 2. Atrigger pulse from a trigger pulse generator 13 turns the Q side of a flip-flop 14 to HIGH level to open a gate 11, starting the motor 2 in the opposite direction. The counter circuit 4 registers the travel of the pen 3 on its plotting sweep. At the appropriate point, the coincidence circuit 6 causes the pen 3 to record a spot on the paper 21. There may be several inputs 7' and coincidence circuits 6' so that several points are plotted per sweep. At the end of the sweep, the switch 17 is closed, providing a signal to change over the flip-flops 14, 15, closing gate 11 and opening gate 12 to reverse the motor 2 for the return sweep. Alternatively, reversal may be initiated by a signal from the counter circuit 4. In a modification Fig. 6 (not shown) the motor drives two pens, each traversing half the chart, and each having its own measuring input and coincidence circuit. In Fig. 7 (not shown) a  single motor drives respective pens over separate charts.
