Title: Seismic hydrophone signal processor - has charge coupled amplifier which suppresses stray signal pick up and stray capacity fluctuations
IPC: G01S1/72
Filed: 1975-05-14
Abstract: The seismic signal system is used for the detection of signals in the form of acoustic pressure waves, which are sensed by a capacitive sensor and fed via an unearthed twisted pair cable to a signal processing unit. The output is connected to a differential amplifier of charge coupled type by which the variable electrical charge at the transducer output is converted to an output voltage. The amplifier includes a stage in the form of an operational amplifier with the output fed back to the inverting input through a feedback chain containing a resistance and condenser in parallel so that the output signal is independent of variations in the stray shunt capacity across the input.

Title: Metal clad laminates mfr. for printed circuit prodn. - by plating metal onto substrate roughening it, oxidising it, contacting it with bonding agent, laminating it, and removing substrate
IPC: B32B15/04
Filed: 1976-08-25
Abstract: A metal-clad laminate is prepd. by (i) applying a release agent to a surface of a substrate, (ii) plating the surface with a conductive metal of thickness 1-20 mu (iii) subjecting the resultant conductive metal layer to a high current density to roughen the exposed surface of the metal, (iv) oxidising the surface, (v) contacting the surface with a bonding agent, (vi) bonding the thus treated conductive metal to a laminate, (vii) removing the substrate, and (vii) recovering the resulting laminate. The metal-clad laminate is also claimed. Esp. useful in forming copper (or other conductive metals such as Ni, Sn, Au etc) clad laminates for use in making printed circuits. The method allows a very thin metal layer to be formed on the laminate so that etching time is greatly reduced, the amt. of etching soln. is smaller, and less undercutting (allowing greater circuit density) occurs.
Patent NL-7706348-A (NL)
Title: Tube heat exchanger for two parallel streams of heat exchange media - with access to both heat transfer surfaces and with no differential thermal expansion
IPC: F28D7/16
Filed: 1977-06-09
Abstract: The tube heat exchanger is constructed of tubes carrying one medium which are, on all sides, in contact with tubes carrying the other medium. With triangular tubes, this is achieved in that each wall of a tube carrying one medium also serves as one wall of a neighbouring tube carrying a second medium. Pref. the tube bundles terminate in a transformation coupling which brings together the flow passages of one medium into common channels and leaves the remaining passages open so that the second medium flows around the common passages of the first medium. A cover plate on the end of the coupling piece has openings corresponding to the flow passages of the first medium whilst a connection on the jacket of the coupling piece allows the second medium to enter or leave the heat exchanger by flowing around these passages. The heat exchanger is so arranged that each medium enters the heat exchanger via the openings in the cover plate at one end and leaves the heat exchanger via the openings in the cover plate at one end and leaves the heat exchanger via the coupling jacket connection at the other end. No special measures need be taken to allow for the differential thermal expansion of the tubes and the shell. The space around the tubes is inaccessible for mechanical cleaning.

Title: Mono:ammonium phosphate and ammonium nitrate prodn. - from phosphate ore via digestion with nitric acid, used as fertilisers etc.
IPC: C05B11/06
Filed: 1977-10-05
Abstract: Prodn. of moammonium phosphate (MAP) and ammonium nitrate (AN) is carried out by (a) digesting phosphate ore with HNO3 to form a mixt. of H3PO4 and Ca(NO3)2, and opt. partially crystallising the Ca(NO3)2 by cooling; (b) adding (NH4)2SO4 to ppte. CaSO4; (c) neturalising the resulting soln. with ammonia to form MAP and AN; (d) crystallising the MAP; and (e) adding a Ca cpd. and ammonia to the remaining AN soln. to ppte. residual phosphate as tricalcium phosphate (TCP). The improvement comprises precipitating the TCP in coarse-crystalline form by adding part of the liquor obtd. during digestion. The crystalline MAP can be used as a fertiliser or converted to (NH4)2HPO4. The AN soln. can be used as a liq. fertiliser or used to produce solid AN or calcium ammonium nitrate. The coarsely crystallie TCP i s readily sepd. from an AN soln. (e.g. in a hydrocyclone) without entraining intert fines, so there is no build up of fines when the TCP is recycled to the digestion step.

Title: Data annotation, input and output system - using paper recording medium having column and line inputs with nodes and node markings
IPC: G06K19/04
Filed: 1979-10-11
Abstract: The data annotation, data input and data output system, uses only one paper recording medium to communicate between computers and computers, humans and humans and computers and humans.

The column and line inputs and markings are produced by a number of standard symbols available on a computer printer. The nodes are produced by standard letters. There is an optical reading system where the meanings of marked or unmarked nodes is determined by the pattern of active reading units and the position of the nodes concerned in the pattern.

Title: Frequency modulator for electronic musical instrument - has combining network for note signals with multipliers and waveform model former
IPC: G10H1/043
Filed: 1980-03-12
Abstract: The signal processing network is for frequency modulating an audio signal to reproduce an effect equivalent to a composition of a number of equal musical sounds. It contains a digital delay line for the audio signal and a timing input whose frequency is determined by the delay. There is also a voltage controlled oscillator, one oscillator for a very low frequency sinusoidal signal and a second oscillator for a one decade higher sinusoidal signal. They are combined to form the control signal. The combining networks are formed by signal multipliers with an added wave shape modelling network, with an exponential transfer characteristic. The frequency of the voltage dependent oscillator is formed by two cascaded units.
