Abstract: A method for the manufacture of a bundle of tubes 3 held in spaced apart relationship by one or more pipe holders 2, in which the tubes of the bundle 3 are introduced through the apertures of an apertured member 1, a mould forming ring 7 is then placed around the bundle of tubes 3 and in contact with the member 1, whereby the member 1 forms the bottom of a cavity mould, and a moulding material 10 (i.e. metal or resin) is placed in the mould cavity so as to fill the space between and around the tubes 3, and when the moulding material 10 has hardened or set the member 1 is moved axially along the tubes 3 away from the holder 2 just formed to a second mould forming ring, whereupon a moulding material 10 is moulded. Any number of holders 2 can be formed using the same member 1. The ring 7 can either be left in position to form part of the holder 2 or removed so that only the moulding material 10 forms the holder 2. <IMAGE>

Title: Stable dispersions containing trialkyltin fluorides
IPC: C07F7/22
Filed: 1979-01-26
Abstract: The tendency of dispersions of trialkyltin fluorides in organic liquids to agglomerate is avoided by using as the dispersion medium specified organic liquids in combination with from 0.5 to 10%, based on the weight of the dispersion, of specified metallic compounds. The choice of both organic liquid and metallic compound is critical to achieving long-term stability of the dispersion. The dispersions are used in marine, anti-fouling paint compositions.

Title: Coal gasifier systems
IPC: C10J3/30
Filed: 1979-03-01
Abstract: An apparatus for handling lock gas which enters a charging lockhopper (12) from a fixed bed coal gasifier vessel (10), after the charging of the gasifier vessel with coal, includes a separator (36) having a fluid inlet (38), a gas outlet (42) and a drain (44).

Title: Elapsed time recorder
IPC: G07C5/08
Filed: 1980-10-09
Abstract: An elapsed time recorder or chronograph comprises electronic timing circuitry feeding electrical pulses to an operating coil (S) of an electromechanical counter. The recorder is arranged to be energised from a d.c. supply 1, 2 which may be at one of a wide range of output voltage values. To accommodate such variations in supply voltage without requiring different operating coils, a low-power pulse generating stage (X1, I.C.I.) including a crystal controlled oscillator and frequency divider counters of the timing circuitry, is energised via a voltage regulator comprising a zener diode D2, diode D1, R5 and C4 such that the pulse generating stage outputs pulses of substantially constant magnitude independently of the d.c. supply voltage. These pulses are fed to a high-power driver stage formed by a VMOS power transistor T1 arranged to produce constant current pulses through the operating coil (S) dependent upon the zener voltage and independently of the supply voltage. The pulse generator stage includes a crystal oscillator (X1) to give temperature stability and accuracy, and may produce one pulse every one hundredth of an hour. Application to the measurement of running time of vehicles is suggested. <IMAGE>

Title: Interruption Protection Arrangements for DC-DC Converters
IPC: H02H9/00
Filed: 1981-02-12
Abstract: On card DC-DC converters incorporate protection against interruption of input power supply by the use of a series diode and a reservoir capacitor. This has the major disadvantage that there is an excessive in-rush of current when the card is first plugged into its connector with the possibility of damage to the power carrying connector pins. This is particularly important in large voltage installations operated at 50 volts. The circuit of the invention provides a method of limiting the in-rush current without disturbing the interrupt protection. The arrangement comprises a parallel resistor/diode circuit (R1, D2) connected in series with the reservoir capacitor (C1). After connection to the input power supply the resistor (R1) allows the capacitor (C1) to charge up slowly. In the event of an interruption of the input power supply the charge in the capacitor (C1) is used through diode (D2) thereby by- passing resistor (R1). <IMAGE>

Title: Waste treatment
IPC: G21F9/10
Filed: 1981-03-17
Abstract: In the treatment of wastes, such as liquid radioactive effluents, it is known to remove radionuclides by successive in situ precipitation of cobalt sulphide, an hydroxide, barium sulphate and a transition element ferrocyanide, followed by separation of the thereby decontaminated effluent. In this invention, use is made of precipitates such as obtained above in the treatment of further fresh liquid radioactive effluent, when it is found that the precipitates have additional capacity for extracting radionuclides. The resulting supernatant liquor may then be subjected to a further precipitation treatment such as above. Decontamination factors for radionuclides of Ce, Ru, Sr and Cs have been considerably enhanced.
