Title: Alarm Signal Systems.
Inventor: BROWN PRESTON REAVES
IPC: G08B19/02
Filed: 1967-05-01
Abstract: 1,189,702. Automatic exchange systems. P. R. BROWN. 1 May, 1967 [27 Feb., 1967], No. 20008/67. Heading H4K. When the temperature in unattended premises falls below an acceptable minimum a thermostat loops a line to an exchange not for the purpose of making a call but to busy the line so that a call to the premises by encountering busy tone can deduce that the thermostat has operated to warn of low temperatures. Since busy tone may also be due to another attempted call to the premises, the premises must be called a number of times to make sure that busy tone is due to operation of the thermostat. The thermostat is disconnected when the premises are occupied and the telephone line is in normal use.

Title: Method and apparatus for continuously producing metal sponge
IPC: C21B13/00
Filed: 1928-07-11
Abstract: 293,868. Flodin, H. G. July 14, 1927, [Convention date]. Metallurgical furnaces; charging and discharging.-In an apparatus for producing metal (e.g. iron) sponge, briquettes comprising a mixture of crushed ore, carbon and a binder are fed from a briquetting machine 13 into a chamber 3, where they are dried and preheated, and then through an adjustable opening 5 into a reducing chamber 4, where they are reduced by the heat produced in the chamber between the chamber 4 and a jacket 8 by the combustion of charcoal &c. and air introduced by tangential pipes 16. Carbon monoxide produced by the reduction of the briquettes falling on the table 6 passes up through the chamber 4 and the openings 17 into the combustion chamber, where it is burnt, and thus assists the heating of the chamber 4. The reduced briquettes in sponge form fall on to a rotary table 6, to which the chambers 3 and 4 are connected, and are removed by scrapers 14 so that they fall into a receiver 9. The gases pass through channels 19 into a chamber 20, where they are mixed with air, and pass through openings 21 in the chamber 3 to dry and preheat the briquettes. Steam thereby developed passes with the gases from the chamber 3 out through a pipe 18.

Abstract: 1,133,825. Semi-conductor devices. SONY CORP. 2 May, 1967 [2 May, 1966], No. 20273/67. Heading H1K. A method of passivating a semi-conductor device having two junctions, comprises applying a layer of a glass-forming material to a selected area of the body, heating in an oxidizing atmosphere to alloy the material to the body forming a first glassy layer, masking the remaining area of the body and part of the glassy layer, removing the unmasked area of the glassy layer to expose a second region, and depositing a second layer of glass-forming material and heating to form a second glassy layer. A double mesa transistor is produced by diffusing phosphorus, arsenic or antimony into a P-type silicon wafer (12) to form two N- type layers (11, 13), Fig. 1 (not shown). The surface of the wafer is oxidized by heating at 800� C. and a layer (18) of a glass-forming material, such as lead or lead oxide, is vacuum deposited over the surface of one of the N-type layers (11) except for the area which is to form the emitter region. The wafer is heated in an oxidizing atmosphere at about 800� C. to produce a glassy layer 20 which extends completely through the upper N-type layer 11, as shown in Fig. 3. The remaining portion of layer 11 and a part 21 of the surrounding glassy layer 20 are covered with a metal mask (22) which may be gold or platinum applied by vacuum deposition. The unmasked portion of the glassy layer is then etched away to expose the surface of the base region (12), the emitter junction being passivated by the glassy ring (21), Fig. 4 (not shown). A further layer (28) of glass-forming material is deposited on part of the base region, Fig. 5 (not shown), and the wafer again heated in an oxidizing atmosphere to form a glassy layer (30) extending through the base region, and to produce a thin oxide layer (29) on the exposed part of the base region, Fig. 6 (not shown). The device is again masked, the excess portion of the second glassy layer (30) is removed leaving a ring 31 passivating the collector junction, and the excess part of the collector region is also removed. Windows are etched in the oxide layers covering the emitter and base regions, and tungsten is deposited to form emitter, base and collector electrodes 33, 34, 35, Fig. 7. The double mesa construction may be circular, square, rectangular or oval in plan view. The glass-forming material may also be selected from aluminium, boron, magnesium, zinc, cadmium, tin and metal halides, particularly fluorides, and mixtures thereof.
