Title: Improvements in internal combustion turbines
IPC: F02C5/12
Filed: 1929-08-08
Abstract: 337,092. Matthews, A. Aug. 8, 1929. Jet-wheels; working-fluid supply. - An internal-combustion turbine has rotor blades receiving impulses from a plurality of rotary combustion chambers arranged round the casing. In the form illustrated the rotor 2 has blades 4, 4<a> on either side of fixed blades 5. Four combustion chambers 7 are arranged on the casing 1. These chambers have diametrically opposite ports 15, 15<a> and are rotated on the shafts 9 from the main shaft 10 by gearing 11, 12, 12<a>, 9<a>, and belts 14 at half the speed of the rotor and in the opposite direction. The cycle of operation is as follows : When one of the ports 15, 15<a> registers with the air admission port 20 in the casing 8, air is forced through this port into the chamber 7 to blow the residual gases out through the port 21 as indicated at A, Fig. 4. These gases discharge by way of pipes 21<a> into the exhaust pipes 29. The port 15<a> then comes into register with the fuel inlet port 22 as shown at B and fuel is injected into the chamber through a valve 30, Fig. 2. Further rotation brings the port 15<a> into register with the ignition port 23 (See Fig. 4) when the plug 23<a> ignites the charge. The opposite port 15 then comes into register with the port 24 leading to the jet 25 whence the gases impinge on to the blades to drive the rotor. Two such cycles of operations occur for each revolution of the combustion chamber. The fuel injector 30 is provided with an adjustable spray control 31 and communicates with a fuel pump 33 of the spring- pressed piston type, operated by the concentric 36 on the main shaft. The pistons have plungers with rollers 40 engaging rockers 41 running at one end of an eccentric 36, and pivoted on a ring 43 at the other end. The ring can be rotated by the handle 44 to vary the strokes of the pistons. The air valves 48 are in the form of tappet valves operated by the eccentric 49 to supply compressed air from the reservoir 51. The reservoir is filled by the compressors 52 of the rotary pump type. The combustion chambers and turbine can be air or water cooled by aid of the passages 70.

Title: Apparatus for monitoring the consumption of electricity
IPC: G01R21/133
Filed: 1976-06-04
Abstract: 1512407 Measuring energy and power FERRANTI Ltd 4 June 1976 [6 June 1975] 24475/75 Heading G1U An electricity consumption monitoring system of the type in which feed pulses, each corresponding to the consumption of a fixed quantity of energy are produced, includes means, Fig. 1, for pre-setting the quantity of energy represented by each feed pulse, means for measuring the time interval between each feed pulse, and means for dividing the feed pulse value by the feed pulse period to indicate the actual load (in watts). The arrangement forms part of a monitoring system particularly for use when the supply tariff permits only a certain maximum amount of energy to be taken during pre-set periods of, for example, 30 minutes. To this end the system also includes a counter which is initially pre-set at the beginning of each period to the maximum amount of energy available and which is then counted down so that it always indicates the amount of energy available in the remainder of the period, a counter which indicates the time remaining in the period, and a second divider which indicates the target load which is the maximum average load (in watts) that can be applied until the end of the period without exceeding the maximum energy consumption for the period. The system also includes a subtractor to indicate how much load has to be shed to stay within the prescribed limit. The Specification describes a block diagram Fig. 4 (not shown) using conventional digital techniques for implementing the system. The maximum demand, and the feed pulse value, are set on decade switches, and the period of the feed pulses is measured by counting clockpulses. Division is effected by counting both the numerator and denominator registers to zero, and re-entering the denominator each time its register reaches zero. One divider is time shared to effect the ten divisions that are required. Various visual and audible alarms may be included if the actual load exceeds the target load by too much.
