Abstract: 107,405. Porter, W. R. June 23. 1916. Seed - distributors. - To maintain the drill formed by seeding or similar agricultural machines constant notwithstanding variations in the surface of the soil, the furrow-forming implement is provided with rotary ground-engaging elements. In the corn-planting machine shown in Figs. 1 and 5, the furrows are formed by pairs of inclined disks 17 mounted on inclined portions of a shaft 14 carried by a vertical supporting-member 13 connected to the axle 11 by a yoke 19. The disks 17 are provided with ground-engaging tread members 18 by which the depth of the furrow is controlled. Tread members of varying sizes may be used. The tread members may be attached by flanges to the disks or may be formed integral with them as shown in Fig. 7. The furrow-opening device is lifted when desired by a hand-lever 23. In the modification shown in Fig. 8, the ground-engaging wheels 41 are mounted on stub axles carried by arms on a frame 39 to which the furrow-forming tool 36 is pivoted at its front end and bolted at its rear end, the deepest part of the tool being arranged in the vertical plane passing through the points of contact of the wheels 41 and the ground. The depth of the furrow is adjusted by releasing the bolt at the rear end of the tool 36 and adjusting it relatively to the arms of the frame 39. In a further modification, the furrow is formed by a disk, the depth of the furrow being maintained constant by an adjustable ground wheel running alongside the disk.

Title: Digital to analogue converters
IPC: H03M1/00
Filed: 1972-02-28
Abstract: 1370716 Automatic control of machine tool ALLEN-BRADLEY CO 28 Feb 1972 [1 March 1971] 9097/72 Heading G3N [Also in Division G4] In a D-A converter having a quadratic compression characteristic, the digital number to be converted is set in a counter which is then counted to zero by clock pulses whose frequency increases in steps. As shown in Fig.1, a numerical error signal in a control system for a machine tool is sampled by register 14 and transferred to an UP-DOWN counter 18 under the control of a sampling clock 19 of adjustable frequency. The counter is then counted up or down according to a sign bit until inverters 51, 53 and 46 detect that it has reached zero. For the duration of this counting a pulse of sign dependent on the sign bit is fed via amplifier 62 to an integrator or servomotor (not shown). Switches 32, 70 are for selection of linear clock pulses (in the position shown) or non-linear in which case counting circuits comprising flipflops (80-84, 98-102) Fig.3 (not shown) and NAND gates (86-96) generate a sequence of pulses whose frequency increases in 8 steps. If the counter 18 has not reached zero before the next sample pulse occurs, an "excess error" signal is generated at 68. In a modification, a down only counter is used for 18.

Abstract: 694,960. Hydrodynamic torque converters. AKTIEBOLAGET LJUNGSTROMS ANGTURBIN. April 20, 1950 [May 10, 1949], No. 9728/50. Class 69(ii) The shafts of the pump, turbine and reaction members extend coaxially from the same side of the casing, the shaft element of the pump being the outermost of the shaft elements and having means such as gears for producing a driving connection with a driving element external of the converter casing the driving connection means being spaced from the rotating casing by a distance only sufficient for the interposition of a bearing supporting the outer shaft element with respect to a fixed housing of the converter. As shown (Fig. 1) pump blades 14 are carried by a rotating casing 12 which is driven by an input shaft 68 through bevel gears 64, 66 and a shaft 58 secured to the casing. Turbine blades 18, 20 are carried by a turbine shaft 22 and this drives an output member 26 in either forward or reverse direction through gearing 28 of any desired known form. A reaction member 48 carrying reaction blades 45 is connected by means of a shaft 58 to one element of a one way clutch 54 the other element of which is mounted in a portion of a fixed housing 10. The left hand end of the turbine shaft carries one element of a friction clutch 36 the other element of which is carried by the rotating casing 12 and by which a direct drive may be obtained. The clutch is engaged by supplying liquid under pressure through a bore 44 in the shaft 22. The housing is provided with a mounting flange 74 by which the transmission may be mounted on an engine the shaft 68 being connected either directly or through an intermediate connecting part to the power output shaft of the engine. If the transmission is mounted as usually intended with the shaft 68 aligned with and directly connected to the engine crank shaft the added length axially of the engine is relatively shorter than with conventional arrangements in which the primary and secondary shafts extend from opposite sides of the transmission. An exceptionally compact unit is provided that can readily be installed in locations where both length and width relative to the axis of the engine are very limited. The rotating casing is advantageously made in two sections so that if the part 12a is removed the interior of the working chamber is readily accessible. All dismantling can be accomplished without having to dismantle the stationary housing from the engine or other mount. The reversing gear and freewheel clutch assembly are readily accessible without having to disconnect the housing from its mount. In Fig. 2 the rotatary casing 12 carries turbine blades 78. Pump blades 85 are carried by a pump member 86 driven by the input shaft 68 through bevel gears 64, 66 and a hollow shaft 88. The reaction member 82 is mounted on a fixed shaft 50 by means of a one way clutch 84. The primary member may be driven by other gearing arrangements or by means of a chain drive to a suitable sprocket on the shaft of the primary member.
