Abstract: 1322127 Sodium aluminium hydride DYNAMIT NOBEL AG 19 April 1971 [18 April 1970] 27299/71 Heading C1A Sodium aluminium hydride is prepared by reacting sodium hydride dispersed in an inert suspending medium with an AlCl 3  etherate and/ or with a solution of AlCl 3  in an ether, the NaH being free-flowing which does not ignite spontaneously in air and which has a particle size of not more than 12Á. The sodium hydride may be ground in the inert suspending medium until it has the required particle size before it is reacted with the AlCl 3  and/or etherate. The Nal[ dispersion may have been obtained by (a) reacting H 2  under pressure with liquid Na in a pressure tight reaction vessel in the presence of sodium hydride initially produced in or intro duced into the vessel in which the reaction is carried out, the contents of the vessel being agitated during reaction, and the liquid Na being added to the vessel during reaction in stoichiometric amounts and at a rate such that the pressure in the vessel remains constant, and that grinding the NaH thus obtained in the inert suspending medium until the sodium hydride has the required particle size. The liquid Na for the preparation of NaH may be added to the vessel during reaction by the pressure of a gaseous medium inert to liquid Na and NaH, the rate of addition of liquid Na being controlled by controlling the pressure of the gaseous medium. The inert suspending medium may be tetrahydro furan, di- and tri-ethylene glycol dimethyl ether and solvent naphtha.

Title: Improvements in or relating to cylinder lubrication for reduction of wear in internal combustion engines on initial starting
IPC: F16N13/16
Filed: 1937-10-12
Abstract: 482,504. Lubricating internal - combustion engines ; reciprocating pumps. FOSTER, R. E. Oct. 12, 1937, No. 27644. [Class 12 (iii)] [Also in Group XXVIII] In an internal-combustion engine a measured quantity of lubricating oil is supplied to the cylinders at starting by means of a pump operated by' the engine suction. The discharge pipe 6 from the pump 1 may discharge directly into the cylinders or into the induction pipe 3. The pump 1 is connected by pipes 2a, 2b to the engine suction and a thermally operated valve 4 may be used so that the pump 1 operates only when the engine is cold. The pump has a pair of cylinders 11, 16, Fig. 3, with connected pistons 21, 19 biassed by a spring 24. Oil from the engine oil sump passes through a boss 12 into the space 18 and thence through a hole 17 into the cylinder 16. The space 25 below the piston 21 is connected to the engine suction and the space above the piston 21 is connected to atmosphere through a valve-controlled duct 33. When starting up the engine cold, the valve 4 opens the space 25 to the suction pressure so that the pistons 21, 19 descend and eject a charge of lubricant through a valve 28 to the engine cylinders. The speed of the stroke varies according to the size of the aperture 33. When the engine is stopped the pistons rise and are again operated when the engine is restarted provided the engine has cooled sufficiently to open the valve 4. The suction to the pump may be controlled manually instead of thermally.

Abstract: 1358317 Cathode-ray tube circuits LICENTIA PATENT-VERWALTUNGS GmbH 16 June 1971 [16 June 1970] 28093/71 Heading H4T A sawtooth waveform 9 (Fig. 1) for use in a dynamic convergence circuit 8 is derived from the secondary winding 6 of a transformer the primary winding 5 of which is connected in the line deflection circuit 1, 2. Waveform 9 is developed across a resistor 7 the value of which, together with the transformation ratio of the transformer and the input resistance of the convergence circuit 8, are so chosen that the impedance transformed into the deflection circuit is small in comparison with the impedance of the deflection coils 3. To enable the polarity of the waveform 9 to be reversed resistor 7 may comprise an adjustable potentiometer having a centre tap connected to a reference potential (ground) such as shown in Fig. 2, and by providing an inductance 11 in series with resistor 7 line fly-back pulses 12 may be derived to enable, in conjunction with waveform 9, a correction signal to be generated which is applicable to both sides of the picture. A resistor 13 in parallel with inductance 11 reduces the tendency of the circuit to oscillate. Pincushion distortion may be corrected by circuit means 14. Instead of connecting the primary including 5 in series with the deflection coils it may be connected in parallel with the latter by employing an L-R integrating circuit to convert the voltage actually applied to the deflection coils into a sawtooth voltage and to make the transformation ratio of the transformer independent of the secondary winding load an amplifier may be connected in series with winding 6. The amplifier may be modulated (e.g. by a triangular voltage from a line pincushion connection circuit) to produce a parabolic modulation which compensates for tolerance variations in the deflection system.
