Abstract: 1,251,859. Sonar systems. FRIED KRUPP G.m.b.H. 11 July, 1969 [12 July, 1968], No. 34989/69. Heading H4D. The rotatable transmitting beam of a sonar installation, for directional sounding in different directions numbered consecutively 1 to n, is switched successively to the directions n/2, n/ 2 +1, n/ 2 -1 n/ 2 +2, and so on (n being an even number). In the Fig. 2 embodiment m (=3) equi-spaced beams are oscillated together so that each scans n (=6) directions in the sequence 2.1, 2.2, 2.3 and so on. The invention is intended to make it easier, compared with the prior art Fig. 1 system, to compensate for the range distortion arising in a plan position indicating CRT display due to echoes from different directions but from objects at the same range being displayed on a spiral arc as a result of sounding pulses being transmitted non- simultaneously in the different directions: for Fig. 2 the range error varies smoothly round the circle, not discontinuously as for Fig. 1. Also, the invention reduces the likelihood of occurrence of two separated displays of one target detected in two beams e.g. beam 1a at position 2.1 and beam 1b at position 2.6.

Abstract: 1,257,531. Control of A.C. motors; control systems for consumption apparatus. GENERAL ELECTRIC CO. 13 March, 1969 [15 March, 1968], No. 13405/69. Headings H2H and H2J. [Also in Division G3] A triac 48, which is connected in series with load 42, is fired by the discharge of capacitor C1, a bridge rectifier D1-D4 having its fullwave voltage clamped by Zener diode D9 and transistor Q13 to supply a ramp-and-pedestal voltage generator and a reference voltage generator from terminals 1, 10. Adjustment of a voltage divider RA, RB, controls the firing angle of the triac in each half-cycle of the A.C. supply. The ramp-and-pedestal generator comprises a timing capacitor C2 which is charged rapidly to a pedestal voltage level from the voltage divider RA, RB. Thereafter, in the same half-cycle, the capacitor C2 is further charged by half sine-wave current through transistor Q10 and resistor Ra. The ramp-and-pedestal voltage at terminal 13 is compared with a reference voltage at terminal 2. Transistors Q3, Q4, function as a differential amplifier, whilst transistors Q4, Q5, present a high impedance to the timing capacitor and compensate for the base-emitter drop of the transistor Q12. When load current flows through the triac 48, transistors Q7, Q8, Q9, are non-conductive to prevent the comparator from delivering a triggering signal, the value of resistor R1 determining the voltage across the triac required to enable the comparator. During operation of the comparator, the transistor Q3 conducts when the ramp voltage becomes equal to the reference potential, thereby keying the switches Ql, Q2 and causing the triac 48 to conduct. The capacitor C2 is reset to a fixed level at the end of each half-cycle by means of transistor Q6. The circuit elements within the line 51 may be embodied in a monolithic integrated semiconductor body including a substrate which is separated from the remaining portions of the integrated circuit by PN junction diodes which are prevented from becoming forward biased; Figs. 5, 6 (not shown). For this purpose, diodes D3, D4, are replaced by an isolation circuit comprising two pairs of transistors, whilst the switches Q1, Q2, are replaced by a bilateral switch. An additional transistor compensates for the low gain of transistor Q12, and diodes D1, D2, are replaced by four base-emitter diodes. The load 42 may be resistive, or consist of a single-phase induction motor with a phase-splitting capacitor. A tachometer generator may be coupled to the motor to provide a control signal across terminals 10, 12, the output of the generator being filtered and applied to a speed-setting potentiometer, Fig. 7 (not shown). The triac 48 may be replaced by a pair of inverse thyristors, each having a pulse transformer, Fig. 8 (not shown).

Abstract: 1,257,699. Furnace roofs and walls. JOHNSMANVILLE CORP. 30 Oct., 1969 [12 Nov., 1968], No. 53157/69. Heading F4B. Portions of a furnace not in contact with the charge or not subject to appreciable bearing loads, e.g. roofs and upper wall portions, are made of low density resilient material of between 96-400 kg./cubic metre comprising an integrated mass of refractory fibre and high temperature resistant binder. The approximate composition range is 60-95% fibre and 5-40% inorganic binder, the former preferably incorporating a filler. An approximate preferred composition is:- 70%-95% refractory fibre 5%-15% organic binder 2%-8% starch or other organic adhesive 0-20% filler. The organic adhesive burns out in use. Suitable fibrous products include those of silica quartz, alumina-silica, alumina, magnesia, hafnia lime, beryllia, zirconia, silicon carbide or boron nitride. Inorganic binders include some clays e.g. bentonite or hectorite, colloidal silica or alumina, phosphates, borates, sodium or potassium silicate and ceramic frits. Organic binders may include starch, elastomeric or resin based adhesives and natural adhesives. Fillers include grog, kyanite, calcined diatomaceous earth, kaolin, alumina, silica and pyrophyllite. The shaped blocks may be produced by filter moulding from a water suspension. The invention is shown applied to a furnace arch in which abutting bricks have complementary slots through which extend flat key bars (Figs. 1 and 2) or H-section bars (Figs. 3A and 3B). In another construction, simple hooks with T-ends embedded in the block material are used to suspend blocks from bars in a flat arch (Figs. 4 and 5). A further modification has T- bars engaging slots in the roof blocks and being themselves slung from H-bars in conventional fashion (Figs. 6 and 7). Another modification, Fig. 8, has hollow units 23 packed with glass fibre or mineral wool 28 and supported by flat plates 25 having hanger rods 26 or wires or chains suspended from a bar 27. Yet another modification has hooked pins engaging washers embedded in the blocks (Figs. 9 and 10) or alternatively, ceramic pins passing through the blocks and having flanged heads engaging the inner surface of said blocks (Figs. 11 and 12). Finally, roof blocks rest on the flanges of H- section refractory brackets, the other flanges of which rest on channel girders (Figs. 13 and 14). An upper wall section, Fig. 15, comprises blocks 43 with slots 44 engaging H-section girders 45 carried by buckstays 46. In a modification (Fig. 16) the blocks are held by large screws embedded therein and extending through vertical backing plates. These latter are attached to vertical buckstays by horizontal bars.

Abstract: 1,258,259. Resistors; capacitors; circuit assemblies. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 27 March, 1969 [5 April, 1968], No. 16638/68. Headings H1M, H1R and H1S. [Also in Divisions Cl and C7] A thin metal or silicon film is bombarded with ions to increase its resistivity. The ions produce a compound with the metal either directly or by sputtering back atoms from the substrate. In the former case the ions may be O<SP>+</SP>, N<SP>+</SP>, P<SP>+</SP> (forming oxides, nitrides or phosphides with the film); in the latter case ions of an inert element (e.g. Ar<SP>+</SP>) may be used. The film may be of Al, Ta, Sn, Cu, Ti or Si on an insulating (e.g. glass) substrate or may be the surface layer of a metallic body. To produce a film of a required resistivity, it is necessary (in order to avoid saturating the film) either to measure its resistance during bombardment or to use doses calibrated for particular films of particular thicknesses. If the range of the ion beam is of the order of the thickness of the film, the resistive compound is formed throughout the film. If the range is considerably less than the film thickness, only the upper layer of the film is affected. This may be dosed to a high resistance and a further layer of film then applied over it to produce a capacitor or (by making a connection to the resistive layer) a RC network. If the range is greater than the film thickness, there is no substantial interaction with the film, but the ions enter the substrate and sputter atoms out of it into the film to form a compound with the film. This method may be used to produce a transparent, conductive Al layer on glass.

In an x-ray analyzer for investigating minerals in situ and including a transducer probe 5 which contains a radioisotope source 8 and a scintillation or proportional counter 9, output pulses from the counter are supplied to a pulse height analyzer 2 which includes an analyzing-and-computing channel 21 having two differential discriminators 24, 25 one of which is turned to a pulse energy corresponding to the secondary emission photo-peak of the element being determined, while the other monitors a region in the scattered radiation spectrum, the ratio of these two counts being indicated on a meter 28. In this way the weight per cent in the mineral of the element being investigated is determined, the count taken by the second discriminator in a region of the scattered radiation spectrum serving as an internal standard. The background count caused by radiation direct from the source 8 is determined by removing the probe from the bore-hole and adjusting each unit 26, 27 to give a pull output in response to radiation from the source only. A further channel 22 may be providing for determining a further element simultaneously. To prevent drift of the detector a feedback loop 23 is provided which includes a discriminator 36 turned to a spectral region outside the range being investigated, this energy range being provided by a second isotope source, if necessary. The pulse count rate recorded by meter 37 controls detector voltage source 38 in such a way as to maintain this count rate constant. A source 45 of pulses of known intensity and frequency is provided for checking the channels 21, 22, 23. The analyzer is used to monitor the composition of the mineral surrounding a bore hole, and by being moved through the hole provides a continuous record of the lead and barium composition, for example, of the mineral.
