A forage crop is fed by belt 20, being precompressed by drum 4 and guided in conjunction with frusto-conical section 46 and flange 44 of wheel 32, to nip 40 of wheels 32 and 34 rotated from chain 70 and sprockets 64 and 66. Wheel 32 consists of hub 54 carrying inner and outer parallel annular plates 72 and 74 and having bevelled edges between which uniform radial die passages 78 alternate with uniform spacer blocks 80; corresponding to plates 88 and 90, passages 94 and blocks 92 of wheel 34. Fodder is continuously fed into the die openings of each wheel alternatively, by rotating in timed relationship with the die blocks of one wheel registering with the openings of the other, and forced radially therethrough to discharge within the annuli at 102 and 104 past shield rings 106 and 108. Plates 74 and 90 are each slit as at 116 to leave tongues 118 and 124 respectively inwardly deflectable to restrict the die passages by means of piston-rod 134 operating from piston 136 of fluid motors 138 (wheel 32) or 150a (wheel 34), one provided for each die opening and, on each wheel, being interconnected in parallel by passages 160 or 162. The motors 138 or 150a are supplied from pumps 168 and 170 respectively; each in turn supplied from reservoirs to inlets 182. Each pump is charged once per rotation by operative engagement of levers 172 or 174, carried on the other wheel, with spring-loaded driving head 194 which operates piston 192 within bore 190. Fluid entering from 182 past check valve 204, upon spring recovery of piston 192, is subsequently delivered, at excess capacity, past check valve 206 into chamber 208 thence via passage 210 to fluid motors 150a. Excess pressure above a predetermined level within motor 150a, either from outward movement of tongue 118 or normally from the excess capacity due to driving head 194, is prevented by connection of the passage 210 to pre-set relief value 214 to return excess volume to the reservoir. In a further embodiment two rows of die openings and blocks are formed by insertion of a splitter plate mid-way between plates 72 and 74 provided with deflectable portions operated from tongues 118 by pressure transmitted through material passing through the die passages.

Tobacco supply apparatus has a rotating circular tobacco conveyer plate 35 arranged for vertical movement between two sets of suction take-off pipes, 9 and 10. The plate, which is of W-cross-section, is mounted in a container 3 on a shaft 38, driven from a motor 43, by belts and pulleys 44-46 at high speed in a clockwise direction. The casing 3 is provided with a funnel 6, for tobacco of one or other sort T1, T2, fed by conveyers 52 and 56 respectively, and has two cylindical casing rings 7 and 8, the ring 7 having the take-off pipes 9 and the ring 8 the take-off pipes 10. The casing rings are held in spaced relationship by webs 13 fixed on a base plate 14. Angle rings 15 and 23 and the rollers 17 and 24 which engage in grooves in rings 20 and 25 which carry supply rings 22 and 27. The rings 22 and 27 are driven in an anti-clockwise direction by the motor 43 via pulley 47, belt 48, pulleys 31 and 34 and friction wheels 28 and 32 which engage the rings. Vertical movement of the shaft 38, and of the plate 35 is effected by an air cylinder 49. Assuming the plate 35 is in its lower position and tobacco of sort T1 has been exhausted on the ring 21, photoelectric cells 59 in the take-off pipe 9 operate a time-switch 61 which controls a valve 51, through a lead 63, to feed an air pipe 54. The cylinder 59 is thus operated to raise the plate 35 to its upper position. Through lead 62 the switch 61 operates a driving motor for the conveyer 55 and tobacco of sort T1 is fed into the funnel 6, the plate 35 then delivering the tobacco to the ring 22. The time-switch 61 is adjusted so that supply is cut off after a suitable amount of tobacco has been delivered. When tobacco of sort T2 has been exhausted on the ring 27, photoelectric cells 64 in the take-off pipes 10 operate a time-switch 65 to lower the plate 35 and start the conveyer 56 for feeding tobacco of sort T2 to the funnel 6.

Title: Velocity xervo system
IPC: G01P3/46
Filed: 1970-08-20
Abstract: 1329991 Automatic speed control INFORMATION STORAGE SYSTEMS Inc 20 Aug 1970 [20 Aug 1969] 40253/70 Heading G3R The access mechanism of a disc storage drive is retracted under energency conditions such as power supply or component failure by an electric motor having a movable coil 16 which develops a velocity proportional voltage across lines 17, 18, the IR drop being corrected by a signal from resistor 23 and the effect of inductive switching spikes being nullified by filter networks 19, 25. The occurrence of an emergency condition causes device 26 to generate a signal which activates transistors 27, 31, to apply a voltage to line 18 and to provide an emitter biasing voltage for transistors 35, 36. An output from summing amplifier 15 activates transistor 36 producing a reverse signal on line 39. Transistor 41 conducts to emit a reverse - acceleration signal on lead 42 and to block any forward signal over lead 37 to the motor control circuit. The motor thus drives the access mechanism at a controlled speed in the reverse direction. Transistor 32 is driven by the amplifier 15 to activate transistor 35 and produce a forward signal on line 37, turn off transistors 36 and 41, and activate transistor 38. The latter produces a forward-accelerating signal on lead 43 and prevents reverse signals being supplied to the motor control circuit. The motor slows down the motion of the access mechanism in the reverse direction until balance is restored between the velocity command input and the velocity feedback to the summing amplifier. When the difference signal drops, transistor 32 is cut off thus interrupting the signals from transistors 35, 38.
