Title: Improvements in or relating to steam generators for extracting heat from the exhaust gases of internal combustion engines
IPC: F22B1/08
Filed: 1966-01-11
Abstract: Feed water from pump 9, pre-heated by heat exchange with boiler water in heat exchanger 6, is fed into the drum 4 of a water tube boiler heated by the exhaust gases of an internalcombustion engine. From the drum 4 the water is circulated by pump 5, in two streams, one stream flowing through steam generating section 2 and back to the drum 4 through line 8, and the other, after heating the feed water in heat exchanger 6, flowing through economizer 3 and back to the drum 4 through line 7. A superheater 1 is provided. The boiler water flow through heater 6 is thermostatically regulated by valve 10 to maintain water entering economizer 3 above a minimum temperature so preventing acid condensation. Variations in steam demand are met by supplying some of the water to the economizer 3 through valve 11 so by-passing the feed water heater 6. This increases the temperature of the water entering the economizer and so reduces the heat pick-up from the exhaust gases. The valve 11 is controlled by the steam pressure in the drum 4. The steam generating section may be divided into four valve-controlled sections in parallel flow (Fig. 2, not shown), to enable one or more of the sections to be cut-off to meet a reduced steam demand. Auxiliary heating means may be provided.

Title: High-speed dc interlocked communication system interface
IPC: G06F13/10
Filed: 1970-06-13
Abstract: In a data communication system, an interface interconnecting terminals has two interdependent interlock systems controlling transmission of discrete units of data. As described, a computer input/output (I/O) channel unit is connected to an I/O device control unit. After an initial selection sequence to select an I/O device as in Specification 1,108,806 (referred to), a byte may be output (written) by the control unit raising a "service in " tag line, to which the channel unit responds by placing the byte on a " bus out " and raising a " service out " tag line, to which the control unit responds by accepting the byte, raising a " data in " tag line and dropping " service in." The channel unit responds by dropping " service out," placing the next byte on " bus out " and raising a " data out " tag line to which the control unit responds by accepting the byte, raising " service in " and dropping " data in." The fall of " data in " causes " data out " to fall. And so on for subsequent bytes. Alternatively, bytes may be input (read), after the initial selection sequence, by the control unit applying byte to a " bus in " and raising " service in " to which the channel unit responds by accepting - the byte and raising " service out " to which the control unit responds by raising "data in," applying the next byte to " bus in " and dropping " service in." The channel unit responds by dropping " service out," accepting the byte and raising " data out " to which the control unit responds by applying a byte, raising " service in " and dropping "data in." And so on for subsequent bytes. The " data in " and " data out " tag lines can also be used in conjunction with the other tag lines (besides " service in " and " service out ") in- Specification 1,108,806 so that the bytes transferred may be data proper, I/O device addresses, commands and orders, and status and sense information, in each case with double the byte transmission rate of Specification 1,108,806.

Title: Control arrangement for a brushless motor
IPC: H02K29/12
Filed: 1978-01-19
Abstract: The invention relates to a control circuit for a brushless self-starting D.C. motor of the type having a permanent magnet rotor and stator coils, a magnetic field-dependent component or sensing coil for sensing the position of the rotor, and controllable electronic switches in respective series with the stator coils and the D.C. source.

A metallic element is attached to the rotor which turns with the rotor past the sensing coil. The position of the sensing coil and the metallic element at will independently of the stator coils. The metallic element may consist of soft iron and be attached to an end face of the rotor. The metallic element may have the shape of a segment and extend over an angle less than 180 DEG so that with regard to the physical dimensions of the sensing coil, control signals displaced in phase through 180 DEG are derivable from the signal of the sensing coil.
