Title: Method for the electrolytical deposition of highly ductile copper
IPC: C25D3/38
Filed: 1970-07-09
Abstract: 1316846 Electrolytic deposition of copper WERNER FLUHMANN GALVANISCHE ANSTALT 9 July 1970 [10 July 1969] 33352/70 Heading C7B Copper is electrolytically deposited from a bath comprising copper pyrophosphate and/or the combination of copper sulphate and potassium pyrophosphate. The method includes (a) before starting electrolysis, passing the bath through at least one micropore filter, and (b) during electrolysis passing the bath through at least one micropore filter, the steps (a) and (b) serving to hold the bath constantly free during electrolysis from particles having a grain size exceeding 3 microns. Thereby the deposited copper is pore-free, has a ductility of more than 6% measured as ultimate linear elongation at room temperature and has a total impurity content of less than 100 ppm. Before step (a), the bath may be purified with an adsorption agent such as active carbon, silica gel, alumina or a molecular sieve. During step (b), the bath temperature may be 30-75‹C and the pH be 7-9. The electrolysing current may be periodically interrupted or its polarity be periodically changed. Alternatively, alternating current may be superimposed on direct current. The method may be used in making printed circuits, the substrate first being rendered conductive.

Patent GB-1339093-A (GB)
Title: Echo-sounding apparatus
Inventor: LEBAIL P
IPC: G01S15/89
Filed: 1972-07-19
Abstract: 1339093 Echo-sounding COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 19 July 1972 [28 July 1971] 33769/72 Heading H4D In an echo-sounding system of the type in which waves reflected from a target are incident on an array of detectors, and in which the detector output signals are sampled and the resulting sampled instantaneous distribution of wave energy over the array is Fourier transformed to produce a representation of the target, allowance for curvatuve of the wavefronts is made by sampling the signals from the detectors at respective instants delayed with respect to a sampling time origin by amounts proportional to the squares of the respective distances of the detectors from a reference point in the array. In the Fig. 1 embodiment a detector array 6 receives pulsed ultrasonic waves reflected from a target 2. The detector outputs are amplified at A1-A1600, frequency-down-converted in mixers M1-M1600 and fed to first sampling circuits E1-E16 and second, similar sampling circuits G1-G16. Sampling circuits E1 and G1 are associated with the detectors located in a first of sixteen angular sectors centred on array point PO, circuits E2 and G2 are associated with the detectors in the second sector, and so on. In each sampling circuit E the outputs of all detectors of a sector are time-divisionmultiplexed by a switching circuit C, sampled and digitized by circuit K then de-multiplexed by addressing circuit T whose outputs are stored in signal memories V. The multiplexing and demultiplexing stages of all circuits E are synchronized by a clock H. A variable delay circuit 16 triggers the emission of pulses from clock H after a time interval, following the transmission of an ultrasonic pulse from transmitter 4, equal to the echo-time of the waves from a target at a given range. After a further time interval, equal to one quarter of the period of the signal at the output of mixers M1- M1600, a similar clock J is triggered to emit pulses for controlling multiplexers Q and demultiplexers U in the sampling circuits G1-G16. The outputs of demultiplexers U are stored in signal memories W. A predetermined number of clock pulses is required to produce each switching action in the circuits E and G; this number may be constant, e.g. unity, if the detectors are regularly arranged in array 6, or may be varied during the sampling cycle if the detectors are arranged irregularly, e.g. in pseudo-random manner. The pulse frequency of clocks H and J, and hence the sampling delay, is varied by device 26 so as to be proportional to target range. The complex Fourier transform of the contents of memories V and W is formed by a calculator TF and controls a display 12. Instead of sampling the detector outputs at mutually delayed instants, the detector outputs may be differently delayed as a function of the square of the detector distance from the array reference point and the delayed signals are then sampled simultaneously (Fig. 2, not shown).

Abstract: 1,182,070. Overload devices for jib-cranes. LANDMASCHINENBAU "ROTES BANNER" DOBELN, VEB. 16 July, 1968, No. 33910/68. Heading B8B. An overload cut-out device for a jib-crane comprises a beam 6, pivoted to the jib 1 at 7, which is acted on at opposite ends by a luffing ram 3, 4, and a spring 8, and which actuates a valve in an hydraulic circuit to prevent motion of the crane in a direction likely to cause overturning when overload conditions are imminent. Over-extension of the spring 8, which may be a compression, tension, torsion or hydraulic spring, is prevented by a stop 11. Fig. 2 (not shown), illustrates an hydraulic circuit and valve 10 which prevent movement of the luffing ram in a direction which would increase the overturning moment when overload conditions are reached. The beam 6 may alternatively control the crane electrically. If a luffing cable is used it is attached to the beam 6 in place of the ram 3, 4.

Title: Improvements in or relating to circuit-arrangements for acting upon the natural frequency of an oscillatory circuit by means of a variable reactance
IPC: H03C3/20
Filed: 1946-11-15
Abstract: 619,085. Frequency modulation. PHILIPS LAMPS, Ltd. Nov. 15, 1946, No. 33953. Convention date, May 6, 1943. [Class 40 (v)] In an oscillator frequency modulated by a variable reactance other than a reactance valve, an amplitude modulated voltage derived from the oscillatory circuit is rectified and negatively fed back to the modulation input so as to obtain a substantially linear relation between the modulating signal and the frequency of the oscillatory circuit. A reactor 4, whose inductance may be varied by modulating signals applied to the grid of valve 8, is in parallel with the resonant circuit 2, 3 of an oscillator 10. Changes in reactance in accordance with the modulation effect changes the current in the primary of transformer 5, 6, from which an amplitude modulated output is obtained. This output is rectified and fed back to the modulation input. To compensate for the component of the current through the reactor 4 that is due to the power losses of the coil-represented as a parallel resistor 13-a current is fed back from the oscillator 10, via condenser 12 and resistor 14, which is substantially equal and opposite to this component. In a modification, Fig. 5 (not shown), the oscillating circuit includes a generator of oscillations of a constant frequency and amplitude to ensure a linear variation of current in the variable reactor as its reactance changes. A filter passing only oscillations of the generator frequency is included in the output circuit of the feed back transformer. In a further modification, Fig. 3, (not shown), the variable reactor is in series with the main oscillator coil, the amplitude modulated feed back voltage being developed across the variable reactor. In another embodiment, Fig. 4 (not shown), a potential variable condenser replaces the variable inductance, the feed back voltage being taken from a transformer whose primary forms a small inductance in series with the condenser. Specification 609,970 is referred to.

Abstract: 1527289 Pipelined processors INTERNATIONAL COMPUTERS Ltd 3 Aug 1977 [17 Aug 1976] 34259/76 Heading G4A A microprogram control unit 12 including a microprogram control store is supplied with microprogram start addresses derived from the latest n instructions, the control store holding a plurality of microprograms and the control unit producing from each microinstruction a set of n control signals, one set for each of n processing stages in the pipeline, whereby different phases of n instructions are executed concurrently by each microprogram. In this way conflicting demands by the processing units DF1-DF3, e.g. for access to the main store 10 can be avoided without complicated interlock procedures. The instruction function codes F are supplied to a decoder 16 which produces signals S1-S3 identifying the operations required for the three possible phases of the instruction, the second phase signals S2 being null in the case of a direct instruction. The signals S1-S3 pass through a pipeline register 17-19 so that control unit 12 is supplied with a start address compiled by a hasher 20 from different parts of three successive instructions. Since this arrangement would require an impractically large number of microprograms, only the most commonly occurring instructions are pipelined in this way, and the less common instructions are recog. nized by decoder 16 and are used to address an individual microprogram in a conventional manner after the pipeline 17-19 has been emptied of preceding instructions. Also to avoid very wide micro-instructions required to control n processing stages concurrently, the relatively static control information may be held in a flag register while the more variable control information is provided by the microinstructions from the control store. The last n instructions are held in registers 22-24 for monitoring and diagnostic purposes.
