Title: Pellet manufacture and apparatus therefor
IPC: B01J2/22
Filed: 1966-03-29
Abstract: 1,102,153. Moulding pellets. F. O. WIENERT. 29 March, 1966 [2 April, 1965], No. 13722/66. Heading B5A. Rounded pellets are produced from a mixture of particulate material e.g. hematite ore, chromite ore, magnetite ore and ore concentrates, ilmenite, alumina, silica-alumina mixtures, iron oxide-silica-carbon mixtures, limestone, and magnesia, with a liquid e.g. oils, thin tars, resins or water, which may contain a binder e.g. sodium silicate, clay, bentonite, starch, glue or cellulose derivatives, which mixture is deposited from a hopper 24 on to an endless continuously moving horizontal rubber belt 11 which is backed, under the upper span 14 thereof, by spring plates 26, 27, vibrated by electromechanical devices 33, 35, which assist compaction of the mixture in a plurality of die holes 23 provided in the belt 11 and into which the mixture is forced by mechanical fingers or pins (not shown) or a die filling means comprising a pair of blades 38 extending transversely to the belt 11 between side plates 40; the belt 11 with filled die holes 23 passes on the lower span 15 thereof, over a resiliently mounted and vibrated supporting grid 61 which is provided with longitudinally extending slots (64) (Fig. 2, not shown), over the area of the die holes so that air, steam, nitrogen or CO 2  pressure, which is independently maintained in a series of transversely extending compartments in a head 46 maintained in sealing contact on the upper side of the belt 11, forces the moulded pellets through the grid 61 on to an inclined table 67 which is longitudinally reciprocated and is provided with a series of longitudinally extending grooves 71 which register with the slots (64) and into one end of which the same or a different dry particulate material is distributed from means (83) whereby the pellets which are still in a plastic condition are rounded in passing along the table to a receptacle (73) at the other end thereof and may also pick up a coating of the particulate material. A lighter coating results if warm air is blown across the table (67) through a nozzle (75) and, where a thicker coating is desired, a liquid is sprayed on to the table through a nozzle (76) on to which finely divided material is also deposited from a vibrating screen (77). Excess liquid exuding from the material compacted in the die holes may be removed by means (not shown). The reciprocated table (86) (Fig. 3, not shown) may be disposed at 90 degrees to the belt with gas pressure hood (88) angularly disposed. The die holes may be tapered (Fig. 4, not shown) or may be lined with silicone rubber or a fluorocarbon polymer (Fig. 5, not shown) to facilitate release of the pellet. The pellets may be rounded in an inclined rotating drum or disc pelletizer instead of on the reciprocating table.

Title: Amplifier circuits
IPC: H03F1/30
Filed: 1975-04-03
Abstract: 1507525 Transistor amplifier NIPPON GAKKI SEIZO KK 3 April 1975 [3 April 1974 4 April 1974 (2) 6 April 1974 10 May 1974 11 May 1974] 13722/75 Heading H3T To bias the gate G of an FET amplifier stage Q 1 a constant current unit CC1, i.e. a high impedance circuit, feeds a resistor R1 across gate-source G-S, while drain D goes to a voltage supply +E1 and the source to an output terminal T5. Such a constant current supply may be an emitterfollower bipolar transistor Q3 or its FET equivalent. In a FET single ended push pull amplifier stage with the inverting transistor Q2 biased similarly the balance between drain currents may be varied by potentiometer VR, and their common level by variable supply E3. The emitter resistors R3, R4 may be replaced by a single emitter follower (Fig. 2, not shown) with differential signal input to the bases of Q3, Q4 also used for balancing. The level of the constant current may be stabilized against variation in supply across T3, T4 by an NPN transistor with emitter and base areas T3, T4 and collector to the - E4 line (Fig. 4, not shown) via a load , the drop across which may be compared with a zener diode reference (Figs. 3, 5, not shown); if required the NPN transistor may monitor the voltage of T4 above ground (Fig. 6, not shown). The above circuits may be used to bias two FET's in series in a first stage, with differential input, feeding an output push pull stage (Fig. 7, not shown). By modification of a source follower to reverse the sign of the D.C. drop across the source load (Fig. 10, not shown) by a constant current bleed, the two stages can be direct coupled. The constant current source required there and in the first stage may be replaced by variable resistors in conjunction with a constant current source in the gate circuit of each second stage FET. The modified source follower, with complementary first and second stage pairs of FET's in push pull provides further simplification (Fig. 11, not shown).

A gaming machine includes a winnings payout device, a counter for counting wins, and a bonus pay-out device controlled directly or indirectly by the counter so that operation of the bonus pay-out device is prevented until a predetermined number of wins have been counted. The counter comprises a rotary switch having banks of contacts 40, 42, 44 and 46. A signal 12 initiates a stepping movement of the switch each time the winnings pay-out device operates, the motor 48 being energized to complete the stepping movement through contact bank 42. On reaching the tenth contact, the switch is driven to its initial position through contacts 10, 11 of contact bank 44. Lamps 1-10 are progressively illuminated to indicate the number of wins recorded under the control of contact banks 40 and 46. The first five lamps are held on when relay 52 is energized through contact 5 of bank 40. To provide a signal 20 when the count of ten is reached, a further bank (not shown) energizes relay 64 through its tenth contact to close switch 66. Signal 20 energizes the bonus pay-out device. In a modification, the signal 20 frees a subsidiary gaming machine controlling a jackpot pay-out device. The subsidiary gaming machine gives odds in favour of the punter and may be operated a predetermined number of times under the control of a random number selector means. The capacity of the counter is set at the start of a count by second random number selector means.
