Abstract: 570,593. Agricultural implen.ents. OLIVER, J H. June 26, 1943, No. 10382. [Class 6(i)] Potato-covering ridging implements are mounted on a frame propelled in front of a tractor. The sides 5 of the frame are pivoted to the tractor rear axle. Clamped to the sides 5 is a square tool-bar 7 supporting ridgesplitting shares 2 and triangular plates 11 which carry the shafts 10 of two rollers in advance of and in alignment with the outermost shares. Scrapers 17 are fastened to metal strips 16 mounted between the end plates. The shares, rollers and scrapers are all laterally adjustable to suit the pitch of the ridges. They may be raised from operative position by a lever 26 acting through a link 25, bell-crank 22 and chain 21, the bell-crank being pivoted to a frame 24 upstanding from the frame of the tractor.

Title: Improvements in and relating to hydraulic speed governing mechanism for prime movers
Inventor: EMERSON REGINALD STANLEY
IPC: G05D13/00
Filed: 1956-04-05
Abstract: 812,164. Fluid-pressure servomotor control systems. BERGER Ltd., B. March 22, 1957 [April 5, 1956], No. 10409/56. Class 135. An hydraulic control unit for a prime mover comprises a pump 1 driven by the prime mover and displacing fluid through a system having a control orifice 5 for building up a pressure to balance a spring-biased slidable member 6 which has porting for controlling an actuating member 16, a spring-loaded accumulator piston 9 for controlling the pressure downstream of the orifice 5 which pressure is used for operating the member 16, and means for varying the force of the biasing spring 13 of the member 6 in relation to the displacement of the member 16. As shown, the member 16 is a differential piston acting on torque-controlling means of the prime mover, e.g. fuel control means, and varying the force of the spring 13 through a lever 23 which engages a spring abutment 25 and has an adjustable fulcrum 24. Any variation of speed of the prime mover causes movement of the member 6 to cause the right-hand side of the member 16 to be connected either to pressure at the outlet of the orifice 5 or to exhaust through a passage 21, the consequent movement of the member 16 adjusting the spring 13 in a sense to assist in restoring the member 6 to its neutral position. The piston 9 maintains a substantial volume of fluid under pressure in a chamber 8 so that the instantaneous power available for operating the member 16 is greater than that being absorbed by the pump thereby enabling rapid adjustment of the member 16 to take place in the event of sudden load-shedding. Since, in the above embodiment, adjustment of the fulcrum 24 to reduce the feedback to zero would result in instability, a modification is described in which the spring 13 is divided by an orificed piston so that displacement of fluid from a chamber 15 due to movement of the member 16 causes a temporary feedback signal to be applied to the member 6. In this embodiment, therefore, the " speed droop " which is inherent in the first embodiment can be eliminated. The orifice in the piston dividing the spring 13 and the orifice 5 may be adjustable by needle valves simultaneously or separately.

Title: Apparatus for converting continuous into intermittent motion
IPC: F16H31/00
Filed: 1959-03-25
Abstract: 884,602. Converting reciprocating into rotary motion; conveying rotary motion. GOLDRING, W. F. March 24, 1960 [March 25, 1959], No. 10440/59. Class 80 (1). Gearing for converting continuous rotation of a shaft 10, Fig. 1, into intermittent rotation of a sprocket 22 particularly for driving a sheet feed conveyer for a cutting and creasing press, comprises a crank 11 reciprocating a slide 13 carrying spaced sprockets 16, 17 engaged by a continuous chain 19 trained in two loops over sprockets 22, 23 and 27, 28 mounted in a fixed frame 15, detents 34, 36 being provided on the sprockets 22, 27 to permit only anticlockwise rotation of the sprockets. As the slide 13 rises and falls the sprockets 27, 22 are alternately stepped round anticlockwise so that an intermittent output may be taken from either or both of these sprockets. In order to prevent overrun the sprocket 22 may carry an abutment 40 engageable at the end of a downstroke with an extension 37 of the slide 13. Similar abutments may be provided for the sprocket 27. In a modification providing positive locking means additional to the one-way detents the crank-shaft 10, Fig. 5, carries a member 50 having on its face an arcuate lug 51 alternately engaging arcuate grooves in the faces of discs 52, 53 rotatable with the sprockets 23, 28. The discs 52, 53 are timed to have their arcuate grooves concentric with the shaft 10 at the ends of the stroke of slide 13 so that they are alternately locked respectively during the up or down stroke of the slide. The one-way detents (not shown) on the upper sprockets serve to relieve the forces on the lug 51. In this construction, the detent, Fig. 6 (not shown) for sprocket 27 is carried by a sleeve frictionally clamped to the frame 15. On release of the frictional clamp the sleeve and detent may rotate to allow the crank-shaft 10 to be moved backwards if required. To prevent overrun the sprocket 22 carries a member 64 having an arcuate recess coacting with rollers on a half-round member 66 rotated by a chain 69 from the crank-shaft 10. The Provisional Specification describes a modification of the Fig. 1 construction wherein the detents 34, 36 and the members 37, 40 are omitted, the upper sprockets 22, 27 being alternately locked by a rotating arcuate lug, similar to the lug 51 in Fig. 5, engageable with arcuate recesses on the sprockets.

Title: Regulating device operating through variations
IPC: G05B13/02
Filed: 1953-04-20
Abstract: 785,286. Automatic control systems. DELAFONTAINE, R. M. G. April 20, 1954 [April 20, 1953], No. 10800/53. Class 38 (4). In an electronic system for automatically adjusting a variable to a maximum or minimum value, a stored measurement of the variable is utilized in the control. In Fig. 2, the variable is measured intermittently, voltages corresponding to each measurement being applied in succession to terminals 3, 4 and voltages corresponding to each previous measurement, temporarily stored by a condenser or motor-driven potentiometer arrangement, Figs. 3-5 (not shown), being applied simultaneously to terminals 4, 5. The two voltages are effective through valves 6 and 7 to produce a voltage corresponding to the difference between the two voltages which, through a valve 21 or 22, produces a voltage between a terminal 24 and a terminal 23 or 25 to control means (not shown) adjusting the variable in steps. The setting of the control means is measured intermittently and voltages corresponding to each setting and to each previous setting are applied to terminals 12, 13 and 13, 14 respectively, by means similar to those for deriving the voltages for application to terminals 3, 4 and 5. These two voltages are effective through valves 15 and 16 to produce a voltage corresponding to the difference between the two voltages which is applied in opposition to the difference voltage produced by valves 6 and 7. The difference of the two differences is reduced to zero by the adjustment of the voltage applied to terminals 12, 13 at each operation of the control means. Hence each adjustment is proportional to the change in the variable resulting from the previous adjustment. Opposition of the two differences is ensured, even when the sense of adjustment changes, by a flip-flop circuit 29, responsive to the sense of such change, selecting one or other of two circuits associated with the outputs of valves 6, 7, 15, 16. The extent of adjustment may be limited by voltages derived from valves 15 and 16 and applied to the grids of valves 21 and 22. Application to controlling the air intake of an internal-combustion engine to maintain maximum efficiency is referred to. Efficiency is measured as a ratio of output torque to fuel pump opening. Abnormal temperature may be prevented by voltages dependent on temperature applied to the grids of valves 21 and 22.
