Title: An improved heat engine
IPC: F02G3/02
Filed: 1919-06-13
Abstract: 151,683. Macdonald, S. June 13, 1919. Combustion-product engines.-A combustionproduct engine comprises a displacer cylinder D not functioning as a heat-exchanger, a regenerator A maintained by heat from the exhaust gases of combustion at a temperature varying from a maximum at one end to a minimum at the other, and means for supplying, during the working cycle, an additional source of heat energy in the form of a hydrocarbon or carburetted air. In one form, the displacer piston P is connected to the crank-shaft Z about 90 degrees ahead of the power piston Q, and, on the upstroke, draws air through a valve K, and forces it on the downstroke through a valve L and the regenerator A into the cylinder D, where it meets a charge of hydrocarbon admitted through a valve 0. The mixture is fired bv the heated air and actuates the piston Q. On the return stroke of the piston Q the hot products of combustion are forced through the regenerator and the exhaust valve M. In a modification, the valve 0 is dispensed with and carburetted air is drawn in at K and forced through the regenerator by the piston P. In this case the charge may be drawn from a receiver into which it has been compressed by the under side of the piston Q. In another form, the regenerator is jacketed and the products of combustion are discharged through an exhaust valve and then pass to the jacket. The exhaust gases may be passed through a second cylinder before being exhausted.

Title: Improvements in or relating to mineral mining machines
Inventor: ANDERSON JAMES
IPC: E21C29/00
Filed: 1957-05-10
Abstract: 864,598. Fluid-pressure servomotor control systems. ANDERSON, BOYES & CO. Ltd. Dec. 12, 1957 [May 10, 1957], No. 14983/57. Class 135. In auxiliary hydraulic mechanism in a mineral mining machine actuating the haulage gear and/or the slewing of the cutter jib, a variable output pump 3 supplying pressure liquid to the hydraulic motor 1 driving the mechanism is controlled by the piston 16 of a device 5 under the control of the piston valve 21 of a pilot device 6 responsive through electromagnetic means 50 to increases and decreases in current load of an electric motor 51 driving the machine. The device 5 is connected by lines 18, 19 to pump output and the pilot device 6 respectively. On small increases in current load the valve 21 moves leftwardly to connect the line 19 to the line 18 through a two-way restriction 54 so that a fulcrum 13 engaging a lever 12 connecting the pump to a crank arm 10 driven by the motor 51 is slowly moved to reduce pump output. Should the current load exceed a predetermined maximum, the valve 21 is moved further to the left to directly connect the line 19 to the line 18 to cause rapid movement of the fulcrum 13 and reduction in pump output. The pump supplies the motor 1 through an overload valve 4 and a hand-operated forward-and-reverse control valve 7. Should the motor 1 experience a predetermined overload, spring-loaded valves 28, 30 will open to connect the pump discharge to act on the right-hand side of the valve 21 to again reduce pump output. A spring-loaded valve 29 ensures that the pressure is sufficient to operate the valve 21. Pump output may be manually controlled by a hand adjuster 14. In a modification, the line from the valve 30 instead of being connected to the pilot device 6 is connected to twin opposed, spring-loaded pistons movable to engage a finger on the actuating rod 43 of the control valve 7 to selectively control the latter valve. Specifications 739,065, 859,949 and 864,599 are referred to.
