Abstract: Power is supplied to a traction motor 26 by the series combination of a battery 30 and the output of a d.c. to d.c. converter machine 10, e.g. a Metadyme supplied via primary brushes 16, 18 from a further battery 20 and having secondary brushes 22, 24 adjustable to vary the motor voltage. In this way, only part of the power for the motor 26 has to be handled by the controller 10. If the batteries 20, 30 have equal voltages, the range of motor voltages is zero to twice battery voltage; if the battery 20 has a higher voltage, an even wider range, including reverse, is obtained. In Figure 6 the voltage across motor 40 is the sum of the voltage of battery 32 and the adjustable voltage of the generator 38 of a Ward Leonard set 34, 38. In a further embodiment, Figure 7 (not shown), the generator (48) is in series with a portion (V2) of a battery to control the motor (50) until closure of a switch (54) cuts out the generator and applies full battery voltage (V1 + V2) to the motor, whose field may then be varied to produce further speed control. <IMAGE>

Abstract: In a heat pump plant, a hot gas heat exchanger (8) is connected to the refrigerant circuit between a compressor (4) and a condenser (5) having a built-in sub-cooler (6), the heating medium side of said hot gas heat exchanger being connected to a domestic water heating device (9). An extra sub-cooler (10) having its heating medium side connected to a separate low temperature heating circuit is interconnected between the built-in sub-cooler and an expansion valve (11). An ejector (12) is connected to the supply line from the hot gas heat exchanger to the domestic water heating device, said ejector being also connected via a domestic water heating pump (13) to the heating medium outlet of the condenser-sub-cooler combination (5, 6). The return line from the domestic water heating device to the hot gas heat exchanger is connected via a line (15) to the heating medium inlet of the condenser-sub-cooler combination. The domestic water heating pump is arranged to provide a flow of water to the ejector via a domestic hot water temperature sensing means, when the domestic hot water temperature is below a predetermined level. The radiator water heating pump included in the radiator circuit is arranged to provide a flow of water through the radiator circuit when the radiator water temperature is below a level corresponding to the outdoor temperature, both pumps being adapted to operate at the various temperature levels prevailing in the domestic water and radiator water circuits.

Abstract: In the case of a high-voltage power circuit breaker having a stationary (22) and an axially displaceable consumable contact (12), having a compression device (7) for compressed gas, having a nozzle (4) through which the switching-off arc (5) burns and through which the compressed gas flows from a compression space into an expansion space, and having a coil (3) through which the switching-off current flows, it is intended to improve the extinguishing capability without having to enlarge the dimensions of the compression device (7) and of the coil (3). This is achieved in that the coil (3) is arranged in the region of the nozzle constriction and surrounds the switching-off arc (5) coaxially. These measures result in axial magnetic blasting of the arc (5) in the high-pressure region of the switching path and in the region of the nozzle constriction, as a result of which energy is pumped out of the magnetic field into a disordered turbulent gas movement, resulting in the arc (5) being severely torn to pieces. Surrounding fresh gas now passes through the arc (5) to a large extent, even in the case of a small amount of compressed-gas and magnetic blasting, and said arc (5) is reliably extinguished. <IMAGE>

Abstract: Wheeled vehicles, the chassis of which carry a compartment-like space, at least one longitudinal side of which can be opened and closed by means of door sections, often present a problem with the opening and closing of these door sections, when the vehicle is standing on uneven ground or is unevenly loaded. The invention describes a solution to the problem cited in respect of these known door sections. According to the invention the rotational forces/movements to which the vehicle structure is exposed are absorbed by an element 19, which is moveable in relation to a fixed pillar 20 functioning as door frame, and the element is moveably connected to the end of a door section 14. <IMAGE>

Abstract: A thermally insulated masonry wall comprising a plurality of thermally insulated barrier layers extending laterally inwardly from the surface of the wall. This is accomplished by placing a nozzle against the surface of the wall and blasting a pulsating air stream containing a thermal insulating liquid which penetrates through the surface of the wall to provide a first barrier layer embedded deeply in the wall and laterally spaced inwardly from its surface. A second operation provides a second but shallower barrier layer. This can be followed by a third or more applications. Each of the resulting barrier layers comprises particles of masonry material coated with thermal insulating liquid and entrapping air in the interstices formed by the coated masonry particles.

Abstract: In time division communication systems one conference technique is to have a processor combine those samples going to a particular station forming a conference having as many subcombinations as there are stations. This approach, while allowing individual station gain adjustment, suffers from its dependence upon a large number of logic operations for a given conference. A modification of this technique is disclosed which uses a distributed structure such that the individual station ports, under local memory and processor control, operate to combine selected time slot samples into a conference sum unique to the station. In this manner gain values may be assigned on an individual listener station basis while the logic processing for the conference is performed in parallel by the ports involved in the conference.
