Abstract: A gas insulating switch constituting a bus section unit for use in a substation. In a dual main bus system in which three-phase batch type gas insulating buses are juxtaposed on the same installation plane, the invention applies to a structure where the gas insulating buses disposed dividedly on the same axis are connected by bus section units. A three-phase capacity breaker (5) is disposed for each bus section at the side of each gas insulating bus disposed dividedly, and a bus rearrangement portion (3a) connected to one of the divided main buses is disposed over the gas insulating main bus (2) disposed away from the breaker and is used for the connection between the divided main buses. Thus, the installation area of the bus section unit is not increased and moreover, viration-proofness can be improved.

Abstract: Spray-drying of a solution containing hydrogen peroxide and sodium metaborate is known per se; these products are very fine and amorphous, and they show an unsatisfactory storage stability. 
<??>According to the invention, these disadvantages are eliminated, if the primary particles obtained by spray-drying are, immediately after they have left the drying zone, fed to a granulator device and granulated in the presence of free water and/or water of crystallisation of the perborate and, if necessary, the granules are dried. The generally amorphous primary particles are converted into granules having an at least partially crystalline structure and a significantly improved storage stability. Advantageously, the process is carried out in a spray drier with integrated fluidised bed or in a compacting granulator device. The process is suitable for producing perborate granules with more than 10 % by weight, especially perborate monohydrate granules with 14 - 16 % by weight, of active oxygen.

Inventor: WILLIAMSON GEORGE
IPC: D06F33/48
Filed: 1988-10-19
Abstract: An out-of-balance control for a laundry machine in which the input to the control is a current signal which is proportionate to the current drawn by a motor (18) which rotates a perforated drum (10) into which fabric goods are loaded. When the drum is accelerated from a relatively low speed, employed in a washing cycle, to a somewhat higher, distribution speed, the input to the control is a "real time" signal which reflects variations in torque required to rotate the drum. The magnitude of these variations is proportional to load unbalance which can cause radial displacement of the drum, machine vibration and damage to its components. The real time signal is averaged. A differential amplifier (24) then subtracts the "average" signal from the "real time" signal, providing an "unbalance torque" signal of alternating polarity. When the "unbalance torque" signal exceeds a given magnitude, reflecting the maximum permissible centrifugal force to be generated by load unbalance, an "unbalance control" signal is generated. The main control (12) of the machine is responsive to this last signal to reduce the rotational speed of the drum.

Inventor: BELLAMY NORMAN WEST
IPC: F03B13/14
Filed: 1989-03-17
Abstract: The present invention comprises a system for converting the energy in a stream of moving liquid such as a river. The stream is diverted by a common and alternating control means into either of two chambers on opposite sides of the stream so that as the stream flows tangentially into one chamber it flows tangentially out of the other chamber into the stream. As the liquid flows into or out of each chamber it swirls so that the hydraulic losses due to inflow into and outflow from the chambers are minimal. The filling and emptying of the chambers causes displacement of air out of one chamber, through a duct and into the other chamber and vice versa. The back and forth movement of the air drives a turbine in the duct, which in turn drives an electrical generator. Performance is improved by causing the stream of flow through a syphon duct structure into which the chambers communicate.

Abstract: The relay has a coil former (1) with two continuous contact chambers on parallel axes, in which contact tongues (41) are arranged. These contact tongues are jointly anchored in a coil flange (2) and, by means of pole shoes (5A, 5B, 6A, 6B) arranged in pairs, form operating air gaps in the region of the other coil flange. The pole shoes are arranged at right angles in a plane at the end in front of the second coil flange (3). They are polarised by means of a permanent magnet arrangement (7) which has a number of poles corresponding to double the number of pole shoes. The permanent magnet poles facing away from the pole shoes are coupled to the bearing side of the contact tongues via flux guiding sheets (9A, 9B). As a result of the permanent magnet regions allocated individually to each pole shoe, independent matching is possible, as a result of which synchronous switching of the two contact tongues (41) is achieved.
