Title: Reverse running servo-control device
IPC: B60W30/18
Filed: 1966-04-28
Abstract: 1,137,982. Change-speed control. RICHIER. 28 April, 1966 [29 April, 1965], No. 18788/66. Headings F2D and F2L. The direction of motion, e.g. of a tamping roller, may be reversed by first setting a single manual control lever 22, to either forward or reverse, AV or AR, which automatically applies the vehicle brake, and disengages the clutch 2, and, on the vehicle speed falling below a preset value, the brake is released, the gear selected, and the clutch re-engaged respectively. To engage forward drive when the roller is travelling in reverse, the driver moves lever 22 to the forward position and holds it there, at the same time releasing the accelerator. As a result of the lever setting, an electrically operated valve 11 opens, enabling a compressed air, or other fluid operated cylinder 15 to operate the vehicle brakes, and simultaneously a valve 12 opens to initiate declutching. When the speed of the vehicle falls below a pre-set value, a vehicle-driven speed-responsive switch 28 operates to close the valve 11 releasing the brakes, and to open a valve 13 which, through a cylinder 17, causes reversing lever 6 to move from reverse R to forward F. During this operation valves 12 and 13 close and the clutch re-engages. The driver then releases lever 22, and applies the accelerator. Overriding manually-operated brake and clutch pedals, 18, 20, and reverse gear control, are provided.

Patent GB-265068-A (GB)
Title: Improvements in or relating to accelerators for dry pipe valves in automatic sprinkler systems
IPC: A62C35/64
Filed: 1926-07-28
Abstract: 265,068. Lewis, L. M. July 28, 1926. Sprinkler, automatic.-An accelerator for speeding up the opening of dry pipe valves in automatic sprinkler systems comprises separate main and auxiliary diaphragm chambers X, Y, Fig. 1, a main valve chamber 4, and a passage 6<1> connecting the diaphragm chambers, a valve 12 in the chamber 4 connected operatively with a diaphragm 16, an auxiliary valve 32 controlling the passage 6<1> and operated by a diaphragm 23, and ducts 24, 25, 26, 28 connecting the main valve chamber with the auxiliary diaphragm chamber at points on opposite sides of the diaphragm 23. The device comprises a body 1 preferably of cast metal, a cover 2, and upper and lower diaphragm chambers 3<1>, 3. The main valve chamber has upper and lower parts 4, 4<1>, Figs. 1 and 2, closed by the spring valve 12. Under operative conditions the chamber 4<1> is connected by a pipe P under an air pressure of 25 to 40 lbs. to the air line of the sprinkler system. The body portion 1 has also an offset portion 20 forming the auxiliary diaphragm chamber closed at the upper end by a spring valve 32 and connected by a duct 24. This duct allows free communication between the chambers 4<1> and 2 and a passage 25 through a dust filter 29 to a minute bore 28. The operation is as follows : with 25 to 40 lbs. in the pipe P the apparatus is maintained as shown with air pressure equalized both sides of diaphragm and atmospheric pressure in X through passages 38, 39, and line pressure in Y through ducts 24, 25, 28. On a sudden fall in pressure in the air line due to the opening of one of the sprinkler heads, a corresponding fall occurs in chambers 4<1> and 22 through the relatively large passage 24. The sudden lessening on the upper side of the diaphragm 23 opens the valve 32 allowing air to escape into the passage 6<1> and so above the diaphragm 16. This deflects the diaphragm 16 against the still lower atmospheric pressure beneath and opens the valve 12, thus placing the chamber in communication with 4 so that pipe line air communicates with the intermediate chamber of the dry valve and so to the atmosphere.

Abstract: 223,964. Andersen, M. July 25, 1923. Moving-tool machines with means for breaking down vegetation.-A hoe is moved transversely to break up the line of beets into separated clumps and one plant in each clump is then isolated, the remaining plants being pulled out between gripping arms. The hoe 35, Fig. 11, is carried with two curved guides 36 on the shaft of a spring- pressed plunger 38 mounted in a cylinder 40 at the end of a connecting-rod. 33, this rod being slotted to take a pivot on a bracket 34 and attached at its other end to a crank pin on a shaft 30 driven from the main wheels of the machine. The depth of penetration of the hoe is controlled by the guides 36 which cause the plunger 38 to be pressed back against its spring when they engage the soil. The clumps of beet left by the hoe are engaged by an horizontal flange on a plate 13 depending from the rear part of the machine. This flange is provided with a tapered slot leading to a circular opening sufficiently large to receive one beet top. After one beet has entered this opening it is isolated from the rest by a transverse bar 22 that is moved between it and the. other plants by a rod 20 which, with a cooperating rod 19, is provided with a universal pivotal mounting in a bracket 21 and is actuated by a cam 10 on a vertical shaft operated from the main wheels. The rod 20 also causes a pivoted part 16 of the plates 13 to be moved to one side, permitting the isolated plant to escape from its opening as the machine moves forward. The remaining plants in the clump are gripped between the bar 22 and a transverse extension 23 of the rod 19 and pulled from the soil. The movement of the rods 19, 20, actuated by the cam 10, is controlled by a trapezoid opening 12 in a plate 11.

Title: Improvements relating to machines for autogenous fusing or cutting
IPC: B23K7/00
Filed: 1949-07-20
Abstract: 681,007. Dividing by fusion. STEINMULLER GES., L. & C. July 20, 1949 [Oct. 1, 1948], No. 19121/49. Class 83 (iv). In a machine for flame cutting metals in which the work may remain stationary or be rotated about its longitudinal axis and a cutting unit may be moved longitudinally over the stationary work or in dependence with the rotation of the work, the mechanical transmission of motion from a main shaft to the work and cutting unit is controlled by hydraulic means. A machine for cutting tubular work 16 comprises a carriage 8 for a burner 30 which is reciprocated over the work 16 resting on bearings 35 and rotated by a chuck 15 driven from an electric motor 3 through a reversing gear 11, a change-speed gear 12 and a shaft 14. The reversing gear 11 is changed by a doubleacting hydraulic cylinder 9 controlled by a hydraulic valve 7 mounted on the carriage 8. The carriage 8 is in dependence upon the rotation of the work by a disc 19 driven through gears 17 from the shaft 14 and having a radially adjustable block 21 engaging a slot on the end of a push-rod 24 attached to the carriage 8. Alternatively the disc 19 may carry a cam which engages a roller on the end of the push-rod 24 and is maintained in engagement with the cam by hydraulic pressure in a cylinder 29 which is actuated when required through a manual control valve 27. A releasable coupling 18 permits the ready change-over of discs 19 for making different cuts or permits disconnection of the drive when the cutter is to be moved independently of the rotation of the work or is to be moved over stationary work. In a modification, a pair of burners 30, Fig. 7, are adjustably mounted on a bridge 53 carried by a burner head 49 slidable on an arm 48 mounted on the carriage 8. A hydraulic motor 43 controlled in speed by a valve 45 on the carriage moves the carriage longitudinally of the work independently of the main drive through a rack-and-pinion 24, 46. For making circular cuts, with the head 49 stationary, the bridge 53 may be rotated by a drive through gears 51, 52, the rack-and-pinion drive 24, 46 being disconnected. For making copying cuts the gears 51 are disconnected and the head 49 moved according to a copying pattern 57 mounted on an arm 58 which is locked in position by a lever 54. The arm 48 on the carriage 8 is simultaneously released by the lever 54 so that it is free to swing about the axis of the driveshaft 47. The pattern 57 comprising a strip bent to shape is followed by pairs of rollers 56 engaging the sides of the strip driven from the motor 43 through the drive-shaft 47, wormwheel 50 and shaft 55.
