Title: Control arrangement and steering of tractors in tandem
IPC: B62D49/06
Filed: 1965-02-22
Abstract: 1,083,903. Steering endless-track tractors in tandem. CATERPILLAR TRACTOR CO. Feb. 22, 1965 [March 19, 1964], No. 7527/65. Heading B7H. Two endless-track tractors connected in tandem include pneumatic steering control means comprising a source of compressed air, steering, brake and clutch control valves at an operator's station on one tractor, and means operable upon actuation of the valves to release simultaneously the steering clutches of opposite hand on the two tractors or selectively release either steering clutch on one tractor. The tractors can thus be steered by first declutching and braking either opposite tracks on both tractors or one track on the rear tractor until the tractors assume a desired angular relationship, and then driving the tractors forwardly along the arcuate path corresponding to the degree of angular displacement. The tractors are coupled by a ball-joint 14 and both controlled from a driving seat 21 disposed in the front tractor and angled at 45 degrees to improve rearward visibility. Throttle pedals 26 control the engines on both tractors, and a clutch control valve 28 and brake valves actuated by pedals 25 control supply of air from compressors 30 and storage tanks 31 to pneumatic actuators which disengage the clutches and apply the brakes in opposite fashion on the two tractors. Valves V3 are pressure-actuated from the valve 28 to isolate the front brake and clutch actuators when desired.

IPC: E04H4/00
Filed: 1968-02-15
Abstract: 1,245,102. Automatic concentration control. N. C. HARPER, J. H. MARSHMAN and H. T. MARSHMAN. Feb.13, 1969 [Feb.15, 1968], No.7537/68. Heading G3R. The water in a swimming pool is repeatedly sampled at intervals and a disinfectant injector automatically controlled in dependence on measurements of the disinfectant concentration in the samples. In Fig.7, a solenoid-operated valve 81 is periodically opened under the control of a cam driven by a motor 24 so that samples of water drawn from a swimming pool by a pump 12 and being returned to the pool at 15 are periodically collected in a glass test chamber 32. Further cams driven by motor 24 cause operation of a pump 83 to add a quantity of chlorine indicator from a tank 26 to chamber 32 and operation of an electromagnetic vibrator 85 to agitate the mixture. The amount of blue light transmitted through chamber 32 and received by a photo-voltaic cell (not shown) is dependent on the concentration of chlorine in the swimming pool and if, for any sample, this is less than a predetermined value corresponding to a small quantity of free chlorine, a bridge circuit including the photo-cell becomes unbalanced in such sense as to operate, through transistors and a silicon controlled rectifier, an electromagnetic relay which adds a dose of chlorine to the pool. The electronic circuit is duplicated for reliability. In a modification, the motor-driven cams mechanically operate a valve supplying water from the pool to the sampling chamber and a piston pump supplying the indicator to the sample which are integral with a glass block forming the sampling chamber.

Patent GB-1539142-A (GB)
Title: Method of producing solid bodies
IPC: B24B5/36
Filed: 1977-02-24
Abstract: A method and apparatus for forming solid bodies by removing material from solid workpieces. A workpiece is situated between oppositely rotating tools which remove material from the workpiece, these tools having hollow interiors facing each other and each conforming to the configuration of one half of the finished body. The hollow interiors of the tools have teeth for removing material from the workpiece, and while the tools are rotated oppositely the distance therebetween is due so that from the workpiece a body is gradually formed, this body finally becoming almost completely enclosed within the hollow interiors of the tools, whereupon the latter have the distance therebetween increased so that the body formed thereby can be removed. These tools are adapted to form from a workpiece bodies of full circular or ring-shaped configuration, and the hollow interiors of the tools are provided with raised teeth similar to file teeth, for removing material from a workpiece. In addition, each tool is formed with openings extending outwardly from its hollow interior so that the material removed by the tool from the workpiece can travel outwardly through these openings.

Abstract: 418,299. Spray carburetters. ENGLEHEART, H. F. R. RAY-, 189, Queen's Gate, South Kensington, London. March 16, 1933, No. 8051. [Class 7 (iii).] An atomizer comprises a nozzle having an aperture through which an axial stream of fluid issues, means for projecting a second stream of fluid at right-angles to and from opposite or all sides inwardly across said first stream of fluid whereby the fluid forming one or both of said streams is thoroughly disintegrated and reduced to a fine state of division, and a convergent conical passage and a divergent conical passage in succession through which the mixed fluids issue. One stream of fluid is conveyed to an axial tube a, Fig. 1, provided with an end member b with a fine axial bore therein, and another stream is fed to an annular passage c which terminates in a peripheral slit or fine bore opening d. The two streams are thus projected across one another at right angles. The atomized fluid issues finally through a convergent-divergent nozzle e, f, the angle of each cone being substantially a rightangle. Between this nozzle and the member b a series of convergent orifices r may be arranged. In a modification, Fig. 3, the atomizer comprises two parts a<1>, a<2> hinged at a<3> so that they may be separated for cleaning, and are normally drawn together by a spring. The parts are shaped to form an atomizing nozzle e, f of rectangular cross-section with an inner passage b for fuel or other fluid and outer passages b<2> for air or other fluid, a cork packing being provided at c<1>. The inner and outer passages are supplied with fluid by conduits such as w<2>. In a further modification, Fig. 4 (not shown), the atomized fluid emerges radially or at rightangles to its general direction of flow instead of axially or in alignment with its general direction. In a still further modification, Fig. 7, the atomizer is applied to a carburetter and comprises two convergent-divergent nozzles t, t<1> and a number of conical passages r. Fuel is supplied through the passage m and air is induced into the passage n through an orifice o.

Filed: 1956-03-15
Abstract: 786,251. Tuning radio receivers. GENERAL MOTORS CORPORATION. March 15, 1956 [May 23, 1955], No. 8103/56. Class 40 (5). A tuner for a radio receiver comprises a resilient device adapted to be loaded manually and arranged when loaded to drive the tuner under the control of a speed limiting device and comprising a lock for arresting the tuner when a signal is received. As shown, the tuning cores 56 are mounted on a cross-bar 58 carried by a carriage 59 movable along a rod 60. The carriage is connected by a pivoted link 66, 68, to the spindle of a gear-wheel 74. The spindle also carries an arm 102 connected by a pivot 104 to an arm 106. This arm carries a combined tuning pointer and knob 126, 124 and when this is moved to the left the tuning cores enter the coils and a spring 62 is charged. Upon releasing the knob the spring causes the cores to enter the coils at a speed controlled by an air governor 92. Tuning continues until a signal is tuned in when a relay 94 is released, allowing its armature to engage the governor. A switch 130, 132 operates when the knob is moved in either direction, causing the relay armature to disengage from the governor. A ratchet and pawl arrangement 72, 76, permits the knob to be moved to the left without driving the governor. In an alternative arrangement (Fig. 2, not shown) the arm 106 drives the governor gear train through a sector gear and carries a lateral extension which when the arm is in its left-hand extreme position mechanically releases the relay.

Abstract: 1,007,887. Hydraulic transmission of power. DOWTY HYDRAULIC UNITS Ltd. Feb. 27, 1962 [March 6, 1961], No. 8108/61. Heading F2D. A hydrostatic transmission comprises a positive displacement pump 2, Fig. 1, connected to a positive displacement motor 5 in which the displacement of the pump and/or motor is controlled by a signal of pump speed so as to maintain the motor speed constant over a range of pump speeds. As shown, the pump is driven from an engine 1 and the displacement of the pump is controlled by a servomotor 37 whose cylinder is movable axially by a manual control lever 43 to determine the control setting. The engine also drives a gear pump 6 which feeds a speed signal device 7 providing a pressure differential, responsive to speed, which is fed by lines 35, 36 to the opposite sides of the spring- loaded servo piston 39. The outlet of the device 7 is preferably fed to a valve unit 9 which controls make-up fluid for the transmission. The device 7, Fig. 2, comprises a spring-loaded valve member 22 having a through passage 25 formed with a restriction 26. The passage also leads to slots 28 by a transverse passage 27. At low engine speeds the restrictor 26 causes a pressure drop insufficient to move the valve 22. As the speed increases the valve 22 moves to open the slots 28, the degree of opening depending on the speed 5 and thus the pressure differential fed through lines 34, 33 to the servomotor is proportional to the speed. The valve 22 may be by-passed by a manually-controlled valve 31 which, when open, provides a fixed restriction for the flow path. Specification 1,007,888 is referred to.
