Title: Silent running internal combustion motor power unit
IPC: F02B77/13
Filed: 1978-06-26
Abstract: A silent-running motor power unit with an internal combustion motor (3) enclosed in a sound absorption chamber formed by a casing, having at least two walls (24, 22a, 23) arranged one (24) inside the other (22a, 23). The walls form part of a labyrinthine channel (6, 1) lined with sound absorption material. To make access and service to the motor (3) easy said walls (22a, 23, 24) include inner (24) and outer (22a, 23) door sections hinged at one of their ends whereas an inner section (24) may be swung outwards through the opening of an outer section (22a, 23). This is achieved by making the sections as a smaller part of a channel wall and as a light plane wall section instead of previously used heavy channel volume type sections.

Title: A vital digital control system with keyboard inputs
IPC: G06F11/00
Filed: 1980-01-25
Abstract: A vital (i.e. fail-safe) digital control system has a keyboard encoder for generating a message based on operation instructions keyed in, the message having diverse pairs of words, a vital decoder for identifying each pair and for producing diverse output words, diverse display words and diverse display echo words, and a display for displaying a representation of the display words.

Title: Solar heated gasification apparatus
IPC: F24S20/20
Filed: 1980-04-15
Abstract: In apparatus for using focused solar radiation to gasify coal and other carbonaceous materials, incident solar radiation is focused from an array of heliostats (19) onto a tower-mounted secondary mirror (21) which redirects the focused solar radiation down through a window (12) onto the surface of a vertically-moving bed of coal, or a fluidized bed of coal, contained within a gasification reactor (11). The reactor is designed to minimize contact between the window and solids in the reactor. Steam introduced into the gasification reactor reacts with the heated coal to produce gas consisting mainly of carbon monoxide and hydrogen, commonly called "synthesis gas", which can be converted to methane, methanol, gasoline, and other useful products. The steam is generated at the rear surface of the secondary mirror. <IMAGE>

Title: A vessel for the storage of granular or powdered materials and a method of emptying said vessel
IPC: B65G65/36
Filed: 1980-11-18
Abstract: A first bottom discharge opening 3 provided at the lower end of a storage vessel and fitted with a shut-off valve is adjacent to a second bottom discharge opening 4 fitted with a shut-off valve.

Title: Float controlled draw off tube for hot water storage tank
IPC: F24H9/12
Filed: 1981-02-06
Abstract: A warm water tank 11 has a valve arrangement 50 comprising an extensible tube having two tube sections, namely a flexible tube section 53 (e.g. of corrugated hose) and a rigid tube section which is closed off at one end, where it has a thread 26 for connection to a weight 27 in a float 25, and which also has an outlet 30 to allow water from the tank 11 to flow through the rigid tube section, the tube section 53 and a subsequently connected flow-off pipe 51.

Title: Method for limiting voltage across series-connected thyristors of high-voltage rectifier
IPC: H02H7/127
Filed: 1981-10-08
Abstract: The method limits voltage across series-connected thyristors 11, 12, etc of a high-voltage rectifier as a voltage surge is applied to the latter and consists in limiting voltage across a group of the series- connected thyristors with a specified number of thyristors in a group, which number is selected to suit the voltage surge parameters. For this purpose, the voltage is measured across the thyristor 11 next to the point where the voltage surge is applied, and then across the following thyristors. As the voltage across the first thyristor reaches a specified level, total voltage across the thyristors is measured, starting from the first thyristor, until it reaches a level equal to the ratio between the voltage surge amplitude and the total number of series-connected thyristors of the rectifier, multiplied by the number of thyristors giving the specified total voltage, corresponding to the number of thyristors in the group. The voltage across the group is then limited to this level, e.g. by switching a specified number of voltage limiters 61, 62 etc across the thyristors in the group. <IMAGE>
