Title: Antenna systems
IPC: H01Q3/46
Filed: 1974-08-22
Abstract: 1485452 Aerials SIEMENS AG 22 Aug 1974 [23 Aug 1973] 36874/74 Heading H4A The Specification describes a computerized phase controlled antenna system of the kind described in Specification 1,333,479, wherein the digital horizontal and vertical deflection phase values #a for a particular beam direction are computed in a phase computer and applied respectively to each digital phase shift device associated with each antenna element wherein the focusing phase value ## for that element has been set by a switch device, and wherein an adder produces the output phase value # = ## + # a  which is applied to determine the radiated phase for the antenna element in question. In Fig. 4 the deflection phase computer 12 calculates the phase values for a specific beam direction for an element (m,n) 13 according to the formula where, H<SP>1</SP> the horizontal phase parameter is given by H<SP>1</SP> = (d.cos # x )/#, and V<SP>1</SP> the vertical parameter is given by V<SP>1</SP> = (d.cos # y )/#, d being the distance between antenna elements. This value (e.g. as a 4-bit word) is applied to an adder 19, Fig. 4 (23 in Fig. 6). The relevant focusing phase value is set in unit 18 and the sum output from adder 19 drives phase shift device 17 which controls antenna element 16. In Fig. 6, the focusing phase value for element (m, n) may be selected from one of either ## 1 (m, n) or ## 2 (m, n), which have been normalized with respect to 2#. Selector switch 22, which may consist of miniature switches or electrical bridges which can be selectively plugged into co-operating spring contact strips, is operated to select the ## value, which value is added to the computed deflection phase value # a (m, n) from shift register 25 in adder 23. Input store 24 stores the summand as a threebit word and drives phase shift network 20 to control the beam phase and direction.

Title: Improvements in the manufacture and production of metal carbonyls
IPC: C01G1/04
Filed: 1928-12-14
Abstract: 327,956. Johnson, J. Y., (I. G. Farbenindustric Akt.-Ges.). Dec. 14, 1928. Metal carbonyls are produced by the interaction of reducible metal compounds such as sulphides, carbonates and oxides with carbon monoxide at high temperatures and pressures. Temperatures between 200‹ C. and 450‹ C. and pressures between 20 and 1200 atmospheres may be used. Substances such as copper, lime, or caustic alkalies may be added to facilitate the reduction of the metal compound. The decomposition of the carbon monoxide may be suppressed by adding to the gas sulphur compounds such as carbon disulphide, or by mixing sulphides such as alkali or alkaline-earth sulphides with the metal compound. Carbonyl-forming metals may be separated from each other and from metals not capable of forming carbonyls. Examples describe the production of carbonyls from nickel oxide, sulphide, carbonate and chloride and from iron oxide and ferrous chloride. Specification 256,428 is referred to.

Title: Improvements relating to transistor circuits
IPC: H03K17/0812
Filed: 1960-11-07
Abstract: 965,421. Protecting transistor circuits. TELEFUNKEN A.G. Nov. 7, 1960 [Nov. 6, 1959], No. 38116/60. Heading H3T. In a circuit comprising a number of transistors 1, 2, 3 (Fig. 3) connected in parallel with their collectors and emitters respectively connected together for a direct current, individual diodes 4, 5 and 6 are connected in each base current path and poled in - a direction to pass base current so that in the event of the collector base current path of one transistor breaking down the diode becomes non-conducting, so preventing damage to the other transistor. In the amplifier circuit shown in Fig. 3 comprising an input transformer 7 and output transformer 8, the diodes are of silicon type and the biasing of the transistors being effected by a network 11, 15. In Fig. 7 the diodes 4, 5 and 6 are connected in series with normally conducting silicon diodes 16, 17 and 18 which together with resistors 19, 20 and 21 provide individual bias for each of the transistors. The resistors 19, 20 and 21 are connected effectively to the collectors through a resistor 26 to provide negative feedback though by connecting them directly to the direct current source the feedback may be omitted (Fig. 4, not shown). In order to protect the transistors against excessive emitter collector voltage due, for example, to open circuiting of the load circuit or induced voltages in the output line a further transistor 27 is connected between emitters and collectors through a resistor 26 and is biased normally to the non-conducting by diodes 28 and 29. If the desired maximum emitter collector voltage is exceeded diode 28 breaks down in its reverse direction in Zener fashion causing transistor 27 to conduct so that the base emitter paths of transistors 1, 2, 3 are effectively short circuited through resistor 26 and the transistor 27. In addition, the change of voltage at the collector of transistor 27 reduces the bias applied through resistors 19, 20 and 21 and provides further protection. Furthermore if the H.T. supply is applied in the reverse direction the transistors are protected by diodes 28 and 29. It is stated in the Specification that the protective arrangement may be applied to push pull circuits.
