Title: Improvements in motor driven implements for ploughing and cultivating
IPC: A01B15/18
Filed: 1923-03-05
Abstract: 194,699. Malbay, R. March 7, 1922, [Convention date]. Rotary - tool implements; ploughs with adjustable tool. frames.-In a motor cultivating implement comprising rotary tools followed by ploughs, each plough being pivotally connected to the casing containing the transmission mechanism for the corresponding rotary tool, the plough is also connected to the casing by a hand-operated screw and a spring, and the casing is pivoted about an intermediate transmission shaft carried by a member adapted to pivot about the driving-shaft. The rotary members A may each be provided with four operating tools B consisting of plates bent at right angles. The members A are each carried by separate shafts mounted in casings K pivoted on an intermediate shaft 0' in a support U which is pivoted on the driving-shaft N<1>. The shaft 0' is driven from the engine by chain and spur gearing and drives the tool shafts by chains e and spring-controlled jaw clutches which slip when the resistance is excessive. The plough beam D corresponding to each rotary tool A is pivoted on the casing K at the joint P and is also adjustably connected to it by a screw I and spring L. The ploughs and rotary tools may be adjusted simultaneously by turning the support U on the shaft N' by means of worm gearing operated manually or mechanically. The rotary tools cut up the upper layer of soil and the ploughs work in a flower layer, the mouldboards F turning over both layers. A supplementary base G may be added to each plough and provided with a share H to work a third layer without turning it over. If the resistance to a plough increases, the pull on the pivot P increases and the rotary tool enters more deeply into the ground and reduces the work to be done by the plough, the tractive effect thus being kept constant automatically. For one-way ploughing two sets of ploughs may be arranged as shown in Fig. 7, the mouldboards of the two sets being right and left handed respectively, and all arranged to turn the soil towards the centre line of the implement or away from it. The two sets are raised and lowered alternately by means of a drum.

Abstract: 823,875. Securing brake discs on shafts. KLAUE, H. Feb. 26, 1957 [March 3, 1956], No. 6460/57. Class 80 (2). [Also in Group XXXIV] In a means of securing a brake disc 4 on the rear axle shaft 3 of a tractor, the brake disc is permitted axial movement along the shaft. A brake actuating ring 20 is rotated so that balls 11 roll up inclined recesses in an axially movable pressure-plate 8 thereby forced into frictional engagement with one side of the brake disc 4, which is then engaged with a brake housing 7. Fig. 7 illustrates an alternative construction applied to a vehicle wheel, in which a brake disc 38 provided with brake linings 37 is mounted for free axial movement on cylindrical extensions of wheel studs 34 which connect the wheel disc 32 to the wheel hub.

Title: Measurement and control apparatus
IPC: B24B49/02
Filed: 1974-02-13
Abstract: 1455607 Automatic control of grinding machines CINCINNATI MILACRON Inc 13 Feb 1974 [13 Feb 1973 10 July 1973] 6580/74 Heading G3N  A grinding machine includes an arrangement for positioning the centre plane of a workpiece (e.g. a ball hub of a homokinetic joint used in front wheel drive cars) with respect to a grinding disc 23, Fig. 3. The disc is mounted on the machine bed 1, while in operation the workpiece 16 is clamped in a chuck 9, 10 supported on a table 2 which is slidable on the bed by means of a motor 5 via a gear-box 4. A feeler rod 15 senses an edge of the workpiece and a first measuring head 17 co-operates with the rod to determine the position of this edge relative to a reference position on the table and therefrom produces a signal as a function of the workpiece width or diameter. A second measuring head 20, secured to the bed, senses the position of the table relative to the bed. An indicator and control unit 19 receives output signals from the measuring heads 17, 20 and compares the value of signal from head 20 with half the value of the signal from head 17. The centre zero position of unit 19 is adjusted so that zero will be indicated when the centre of the workpiece is aligned with the central plane of the disc and the compared values are equal. Any deviation results in an output from the unit 19, indicating the magnitude and direction of the deviation, to a motor control device 7 which switches on the servomotor 5. Thereby the table 2 is displaced until the indicator returns to zero - whereupon the motor 5 stops - and the centre plane of the workpiece is aligned with the grinding disc.

[Classes 39 (i) and 40 (v)] In ultra high-frequency amplifiers wherein the electron transit time is greater than the oscillation period to be amplified the ends of the output impedance are connected to two electrodes located in the path of the electrons and at a distance apart so that the transit time of the electrons between these electrodes is less than half a period of the oscillations to be amplified ; in a pentode where the mesh of the suppressor grid is wide the electrodes considered are the anode and screen grid and in one construction for use with wave lengths below 1 m. the distance between these is less than 3 mm. and the suppressor is shaped as a window. With a distance of 0.8 mm. the minimum wavelength would be 6 cm. For tubes using secondary emission a screen grid 11 is placed between the control grid 10 and the secondary emission electrode 12 ;the output impedance 16 is connected in push-pull to the anode 8 and secondary electrode 12 the centre of the impedance being earthed. A screen 17 earthed for high frequencies is placed between the anode and secondary electrode 12 the distances being such that the electron transit time between the screen and either of these electrodes is less than half a period of the oscillations to be amplified. In a modification where the distance between the anode and secondary electrode is great two screens are used one at the requisite distance from each electrode. With more than one secondary emitting electrode a screen grid is used with each one that serves as output; to earth the screens a Lecher wire system is used, those screens and emitting electrodes not serving as output being connected to voltage nodes. Electric or magnetic focusing is used to maintain uniform transit time. Means to reduce the input and output damping are used. Specifications 495,839 and 499,218 are referred to.
