Title: Scanning phased array antenna system
IPC: H01Q3/36
Filed: 1973-12-17
Abstract: 1454554 Aerials INTERNATIONAL STANDARD ELECTRIC CORP 17 Dec 1973 [18 Dec 1972] 58386/73 Heading H4A A scanning phased array system has N aerial elements but only M phase shifters, M being less than N. As shown in Fig. 3, for a linear array, input to a terminal 17 of a distribution network 16 is divided into M outputs which are fed via respective phase shifters to the M inputs of a subarray interconnecting network 15. The network 15 has N output terminals, which are connected to respective ones of the N aerial elements. As shown in Fig. 5, there is provided in said network 15 a power divider associated with each input, e.g. dividers 24, 26 for the inputs from the phase shifters 28, 29. Each divider has a direct feed to a main aerial element contained in a first group, e.g. the elements 19, 21, and has branch feeds for aerial elements which are at the sides of the main aerial elements, and which are contained in a second group. Coupler means are provided for combining the branch outputs from the power dividers associated with each pair of adjacent main elements for feeding those elements of the second group which are disposed between said pair of main elements. Thus, a coupler means 25 combine branch outputs from the power dividers 24, 26 to feed an element 20 which is between the elements 19, 21. Each main element together with the second group elements on each side of it forms a subarray, and it is shown that a limited scanning may be achieved without grating lobe formation. In another embodiment, a first group of main aerial elements 30 to 36, Fig. 7, are located at the centre and vertices of a hexagon and a second group of elements 37 to 48 are located one between each adjacent pair of main elements. Phase shifters feed power dividers associated with each main element. Each power divider has a direct output to its main element, and branch outputs to coupler means associated with each element of the second group adjacent said main element. Each coupler means therefore receives two inputs, which are combined to feed the associated one of the elements 37 to 48.

Title: Furnace installations and combustion control systems for vapour generators including such installations
IPC: F23N5/18
Filed: 1972-12-18
Abstract: 1411119 Anti-pollution arrangements for furnaces BABCOCK & WILCOX CO 18 Dec 1972 [16 Dec 1971 24 March 1972] 58420/72. Heading F4B The formation of oxides of nitrogen in the combustion gases of a furnace is reduced by withdrawing part of the combustion gas, cooling it and mixing it with the combustion air in an amount proportional to the flow of air. The air flow is measured by detecting the pressures at the front P1, Fig. 2, and the throat P2 of a convergent-divergent nozzle. As shown, this is formed by an airfoil 28, although a venturi tube may be used instead. The combustion gases from the furnace 212, Fig. 7, pass over steam heating surfaces 213 and then downwardly over heat exchange surfaces 214, being discharged through a combustion air heater 216 of the rotary regenerative type. Part of the combustion gas is withdrawn by duct 227 and fan 235. Part of this gas goes to plenum chambers 228 to be passed into the furnace and mix with new combustion gases. The remainder is introduced into the combustion air in duct 217 by means of a number of airfoils 22 each of which has openings 40, Fig. 2, in the tapering portion, the combustion gas passing from the interior of the airfoil through the openings to mix with the combustion air. The slots are longer in the direction of airflow than they are wide. The control system (Fig. 4, not shown) is described.

Filed: 1972-12-20
Abstract: 1456973 Induction heating ELECTRICITY COUNCIL 18 Dec 1973 [20 Dec 1972] 58918/72 Heading H5H Induction heating apparatus for heating steel billets 10 has one or more induction heaters each having an elongate ferromagnetic core 12, Fig. 1, 50, Fig. 5, with an even number of upstanding portions 13, 14, 15, 16, Fig. 1 that extend along the length of the core, an inductive heating coil or coils 20, 21, Fig. 1, 52, 53, Fig. 5, lying in the slots between the portions 17, 18, 19, Fig. 1, the height of the upstanding portions of the core being non uniform along the length of the core so that the air gap between core and billet and hence heating effect is also non-uniform. Cores and coils may be gas or liquid cooled. The core may be laminated. The slots may be filled with an insulating material. Windings and current supply are arranged to be in phase in adjacent windings to enhance the heating effect of the centre of the inductor. In an installation where the billet 10 runs on rollers (27, Fig. 3, not shown) a number of such inductors (28) each covered with a protecting layer of refractory material 29 may be mounted on a lifting device 30 and used to lift the billet clear of the rollers. The inductors may be mounted in a supporting floor Fig. 1 beneath a layer of refractory material 23, impervious to iron oxide slag, a layer of refractory bricks 31 and embedded in a refractory material 11 on which the billet 10 rests. In (Fig. 4) two elongate U-section cores (33), (33) are linked by a transverse ferromagnetic yoke (36) with an upstanding "tooth" (37), a single winding (35) lying partly in one and partly in the other core.

Patent GB-1440960-A (GB)
Title: Camera mechanism having a multiple exposure photographic device
IPC: G03B9/08
Filed: 1973-12-27
Abstract: 1440960 Multiple exposure mechanism ASAHI KOGAKU KOGYO KK 27 Dec 1973 [30 Dec 1972] 59742/73 Heading G2A A camera has a drive which actuates both the film winding mechanism and the shutter cocking mechanism, an externally operable member 7 being provided which can disconnect the drive from the winding mechanism so that only the shutter cocking takes place, thus permitting multiple exposures, and an arrester member 11 which holds the member 7 in the multiple exposure position until it is released therefrom as the drive nears the end of its movement. As shown, a claw 2 is normally spring-urged anti-clockwise so that it will engage one of the lugs 5a of a film winding gear 5. Thus as a driving shaft is rotated anticlockwise, the claw 2 engages and drives the winding gear 5 anti-clockwise. The same driving shaft carries a gear 30, which meshes with and drives a gear 22 which actuates the cocking mechanism. A sliding member 7, operable from outside the camera by means of a knob 7b, is normally urged to the right by a spring 8 (position of Fig. 3). For multiple exposures, it is slid to the left, against the spring, and is retained in that position by the stepped portion 1 1a of a spring-loaded arrester plate 11. During this movement a pin 9 on slide 7 engages claw 2 and pivots it out of engagement with gear 5. Thus when the driving shaft now rotates, the drive is transmitted only to the shutter cocking gear 22, and not to the film wind, so that repeated exposures may be made on the same film frame. A cam member 14 is attached to the drive shaft, and as this reaches the end of its rotational movement a lug 14a thereon engages and pivots member 11 clockwise, so that it disengages from the pin 10 of slide 7, so allowing the slide to move to the right. Thus the drive to the film wind is once more operative. A normally operative frame counter can also be disabled at the same time as the film drive.

Title: Vector peak picking computing system
IPC: G06F7/22
Filed: 1971-12-23
Abstract: 1376179 Vector computing system TEXAS INSTRUMENTS Inc 23 Dec 1971 [4 Jan 1971] 60073/71 Heading G4A A circuit, e.g. in a digital electric computer system, is arranged to pick peaks or valleys in a vector stream (Fig. 2, not shown). A vector X is defined as the ordered array of elements (X 1 , X 2 , X 3  ... ,X #(x) ). X i  is the ith component of vector X and the number of components V(x) is called the dimension of x. A numerical vector X may be multiplied by numerical quantity K to produce the scalar times vector multiply k x X (or kX) defined as vector z where z i  = kxX i . A matrix M may be formed from a two dimensional array of elements. The hardware shown is part of the arithmetic unit of the computer and the input and output lead to the memory buffer unit. The peak picking can be carried out with either fixed or floating point operation. The first two vector elements enter registers 23, 21 respectively and are subtracted in adder 27. Depending on the result (i.e. positive-zero or negative) the gradient of the stream is determined. Then the second and third elements are subtracted and the gradient determined and, if they are opposite, a peak (or a valley) is indicated. The index of the element where a peak or valley occurs may be read out and the computer may stop here or go on to determine all the peaks and valleys of the stream using the same technique. Read only microinstruction signals are mentioned.

Title: Display arrangements
IPC: H01J17/49
Filed: 1970-12-23
Abstract: 1314110 Discharge display tubes WESTERN ELECTRIC CO Inc 23 Dec 1970 [24 Dec 1969] 61072/70 Headings G4H and G5C [Also in Division H1] A display arrangement comprises a stack of display devices 101, 102, 103 each of which has an array of crosspoint display regions defined by a first and second set of conductors such as R11-R111 and C11-C18, with a gas in each of said regions and light attentuating means 121, 122 between each adjacent pair of arrays. The gas and the conductors may be separated by dielectric material 51, 52 in the form of sheets, or alternatively, Fig. 5, (not shown), each conductor may be individually encased by dielectric material and removably mounted in the stack. By addressing suitable discharge voltages to selected cross-point regions, an array of discharges each of brightness depending on which, if any, of the devices have a discharge at a particular point, may be seen from the viewing surface. The light attentating factor of each of light attenuating means is preferably 2, which with n devices permits display of a grey side having 2<SP>n</SP> steps. This arrangement is particularly suitable if the input is in binary form which can be addressed to the devices using circuitry described with reference to Fig. 6 which shows three display cells Xa, Xb Xc of a single cross-point. A sustaining voltage insufficient to initiate a discharge is applied across cells Xa, Xb, Xc from source 620 through OR gates 623. An address circuit 630 has two sets of outputs, one set being leads 631 to 63m which define the cross-point, in this example lead 635, and the second set D1 to D4 which determine the brightness of the display at that cross-point. Address gates 645-648 each have one input terminal connected to lead 635 and the other connected to respective ones of leads D1 to D4, the outputs being taken to the second inputs of OR gates 623. An input circuit 650 receives a binary input signal representing the brightness of the display required and the bits of the signal are fed one-by-one to address circuit 630 whereby the required combination of discharges in cells Xa, Xb, Xc is achieved.

Filed: 1969-12-17
Abstract: 1,270,729. Missiles. TELEFONAKTIEBOLAGET LM ERICSSON. 17 Dec., 1969 [19 Dec., 1968], No. 61570/69. Heading F3A. [Also in Divisions G4 and H4] A missile target selector comprises a receiver connected to an antenna, a video quantizer connected to the receiver and feeding a counter which counts the number of quantized video pulses received while the antenna scans through a predetermined angle, wherein at the end of said angle scan a number generator chooses an arbitrary number less than or equal to the content of said counter and the antenna then rotates in the opposite direction and stops on a target indicated by said arbitrary number. Echo signals are processed in quantizer 4 which produces pulses of constant amplitude and length, the number of pulses being determined by the echo pulse length. These pulses are counted by an analogue or digital counter 7 which provides an output to a comparator 9, the second input to which is the output of a fast running counter 8. When the comparator inputs are equal, it provides a pulse which resets counter 8 to zero and starts it counting again. When the antenna has scanned through the predetermined angle counter 8 is stopped and is thus at a number less than or equal to the number of targets detected. Counter 7 is now reversed and counts down as the antenna rotates backwards. When the comparator inputs are again equal the antenna is stopped and the missile is locked on to that particular target. In a second embodiment, after the arbitrary number has been chosen as before, counter 7 reset to zero at every transmitter pulse as the antenna scans backwards. Before resetting the counter 7 content is subtracted from the counter 8 content and when these are equal the antenna stops. Units 5, 6 are provided to detect either single or group targets and place the range gate pulses accordingly.

Abstract: 782,458. Velocity-modulated tubes. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. April 6, 1955 [April 6, 1954], No. 10127/55. Class 39(1). Tuning of a reflex klystron is effected by simultaneous deformation of the highfrequency cavity and movement of the reflector electrode by means of a hollow cylinder which slides without turning inside a coaxial guide whose outer wall is rigidly fixed to the envelope of the klystron. In the schematic arrangement shown the cavity resonator 10 comprises a flexible wall 40 soldered to a cylindrical member 60 which supports the reflector electrode 70 through the intermediary of an insulating washer 150. The member 60 slides in a guide 50, this movement being limited by shoulders 600 and 610 on the member 60 which abut shoulders 510 and 520 on the guide 50. A glass cylinder 700 is sealed to the guide 50 and to a flexible diaphragm 80 which bears against a domeshaped portion 140 of the member 60. A compression spring 100 engages the shoulder 510 and an abutment 630 on the member 60. Deformation of the diaphragm 80 is controlled by a knob 90. If the knob 90 exerts a downward force on the diaphragm 80, the member 60 and reflector 70 are moved downwardly, and member 60 exerts forces which are parallel to the tube axis on the wall 40. If the knob 90 is moved upwardly, the member 60, reflector 70 and wall 40 are moved upwardly by the spring 100. A practical tube construction embodying the above features is described in which the walls of the cavity resonator are made of pure silver and the other metal parts of the tube are made of an alloy having practically the same coefficient of expansion as glass. The tube also comprises an electron gun constructed as a unit in which the cathode is positioned relative to a Wehnelt cylinder by an arrangement of distance pieces and silica washers, the Wehnelt cylinder is positioned relative to an outer cylinder by a spring and two mica washers and the outer cylinder is secured in position relative to the body of the klystron by a nut bearing on lugs formed integrally with the cylinder.
