Abstract: A controllable fire ventilator has opening springs (13) and dual day-to-day controls one of which is a pneumatically operable piston-and-cylinder unit (20) and the other of which is an electro-magnetic device (30) which retains a keeper plate (33) when the device is energised. The unit (20) may be powered to close the ventilator when the ventilator is open, the control cable (22) carrying the keeper plate (33). Fire response may be by means of a fusible link (35). In an alternative arrangement (see Fig. 3), the electro-magnetic device (30) is incorporated into the cylinder (121) of the cylinder unit and the piston (126) carries the keeper plate (33). A fire switch (140) may open in response to an electrically signalling fire detection system, the cylinder unit (120) being exhausted to atmosphere through its power connection (122) by valve means adjustable only upon operation of a sprinkler system, to avoid ventilator opening in response to false alarms.

Abstract: An electrostatically charged image is applied to a smooth surface and moved past a development zone (15) in which a carrier sheet (25) perforated with a multitude of bores is also located. A layer of developing liquid (26) is applied under gradually increasing pressure to a first surface of the carrier sheet (25) so that the applied liquid squeezes through the bores to and beyond a second, opposite surface of the carrier sheet. The liquid emerges above the opposite surface of the carrier sheet to produce a multitude of part-­spherical bulges. Field concentration occurs on the part-­spherical surfaces of the individual tiny bulges. The first surface of the carrier sheet preferably exhibits lyophilic characteristic to the developing liquid, while the second surface exhibits lyophobic characterisitic.

Abstract: A known device for transferring tuning data into receiving units exhibits a non-volatile tuning data memory from which the tuning data are transferred into the tuning data memories of the receiving units. The feeding of the tuning data into the known device is cumbersome, using a keyboard arranged on the known device. In the novel device, it is intended to simplify the feeding of the tuning data. This is achieved by virtue of the fact that the device for transferring tuning data into receiving units exhibits a connection socket via which the tuning data to be stored in the non-volatile tuning data memory are fed in.

Abstract: An inpage buffer (26) is used between a cache (22) and slower storage device (28). When a processor (12) requests data, the cache is checked to see if the data is already in the cache. If not, a request for the data is sent to the slower storage device. The buffer receives the data from the slower storage device and provides the data to the processor that requested the data. The buffer then provides the data to the cache for storage provided that the cache is not working on a separate storage request from the processor. The data will be written into the cache from the buffer when the cache is free from such requests. The buffer is also able to provide data corresponding to subsequent requests provided it contains such data. This may happen if a request for the same data occurs, and the buffer has not yet written the data into the cache. It can also occur if the areas of the cache which can hold data from an area of the slower storage is inoperable for some reason. The buffer acts as a minicache when such a catastrophic error in the cache occurs.

Abstract: A process for continuously preparing silane and a coproduct by reacting a metal hydride such as NaAIH 4  with a silicon halide such as SiF 4 , utilizing, in conducting the reaction, equipment which includes, in series, a primary reactor, a secondary reactor and a separation zone. The metal hydride is reacted in the first reactor with less than a stoichiometric amount of the silicon halide, and the unreacted metal hydride is then passed to the second reactor wherein the remainder of the hydride is reacted in the secondary reactor, in which a stoichiometric excess of the silicon halide is added. The rate of silicon halide or metal hydride addition is governed by a temperature differential feedback from the reaction in the secondary reactor so that overall a stoichiometric or substantially stoichiometric operation is achieved. Techniques are also disclosed for splitting the silicon halide feed between the liquid and vapor phases of the secondary reactor to eliminate the hazard of combustible mixtures, and, with variable speed agitation of the liquid, to control the mass transfer characteristics of the reaction. Also, consistent kinetics result from control of residence time by varying the liquid level in the secondary reactor as related to the halide or hydride mass flow rates. These improvements conserve resources, provide improved coproduct and reduce costs.
