Patent GB-1099014-A (GB)
Title: Improvements in or relating to electrical pulse-stabilising circuits
Inventor: ROCKEY LESLIE GEORGE HENRY
IPC: G05F3/18
Filed: 1963-11-06
Abstract: 1,099,014. Stabilizing pulse amplitude. BRITISH AIRCRAFT CORPORATION (OPERATING) Ltd. Nov. 3, 1964 [Nov. 6, 1963], No. 43839/63. Heading H3T. [Also in Division G4] A pulse produced by a switching device (e.g. a transistor fed from a bi-stable circuit) is stabilized in amplitude by connecting a Zener diode and a regulator resistor 4 (Fig. 1) in series with the switching device, and shunting these two with a low resistance 2. The output, which is suitable for operating a voltage analogue-to-digital converter (see Division G4), is taken through a series resistor 5 to minimize the effect of the load impedance. This resistor should have a temperature coefficient similar in magnitude and sign to that of the Zener diode. The circuit shown can be inverted, with a PNP transistor, if a negative pulse is required. Further stabilization can be obtained by including a resistor in the collector circuit of the transistor to ensure that it is driven into saturation, temperature-dependence thus being reduced.

Patent GB-1047897-A (GB)
Title: Improvements in or relating to electrophoretic coating
IPC: C25D13/22
Filed: 1964-11-02
Abstract: In a method of electrophoretic coating wherein a workpiece is immersed as an electrode in an electrophoretic bath, the electric current supplied to the bath is initially caused to remain substantially constant until the resistance between the workpiece and the other electrode or electrodes in the bath rises to a certain value, and thereafter the applied voltage is caused to follow a desired function of time, e.g. a linear rise with time, the electric current in the bath being sufficient to maintain electrophoretic action in the bath whilst the desired functions are followed, and such that the tendency for the current to vary as the resistance of the workpiece varies is at least partially counteracted. In an embodiment described for carrying out the regulation of current and voltage in an electrophoretic bath, the bath 1 is fed by direct current derived from a three-phase current supply system by a rectifier bridge 2, an actual value sensing arrangement 3 being situated between the bridge 2 and the bath 1, which supplies signals representative of the actual values of current and voltage supplied to the bath to a current regulator 5 and voltage regulator 6, respectively, via a converter 4 and switch 8.  The position of the switch 8, which may be varied automatically by the sensing means 3, determines whether regulation of current or voltage takes place, and a setting member 7 is adjusted by the operative regulator to produce the desired value of current or voltage to be fed to the bath 1. <PICT:1047897/C6-C7/1>

Title: Hydroxy alkyl sulphonic acid esters of acidic chlorophyll derivatives
Inventor: MITCHELL WILLIAM
IPC: C09B47/00
Filed: 1963-11-13
Abstract: The invention comprises hydroxy-alkyl sulphonic acid esters of the acidic chlorins and rhodins and alkali metal salts of such esters, which chlorins and rhodins have been produced by the hydrolysis of chlorophylls a and b.  They may be prepared by reacting a sultone with a water-soluble chlorophyll derivative obtained by the alkaline hydrolysis of chlorophylls a and b essentially in the presence of a catalytic amount of water.  The reaction can be carried out entirely in aqueous solution or in an organic solvent such as toluene 1,4, dioxan or acetone with water present.  One or more of the free carboxyl groups (as an alkali metal salt) of the chlorophyll derivatives is believed to react with the sultone to give an ester, e.g. with 1,3-propyl sultone to give R.CO.O(CH2)3SO2-ONa, where R represents the rest of the chlorin or similar chlorophyll derivative. The term "chlorophyll" includes compounds in which the chelated magnesium of chlorophyll properly so called has been replaced by hydrogen or by another metal, preferably a heavy metal, such as copper.  Examples describe the reaction of sodium copper chlorophyllin, sodium potassium chlorophyllin and sodium chlorophyllin with 1,3-propyl sultone.  The compounds may be used for imparting a green colour to canned peas and vegetables and for colouring various other foodstuffs (see Division A2).

Title: Differential capstan for multiple tape sizes

Filed: 1964-11-04
Abstract: 1,027,878. Driving record tapes. MINNESOTA MINING & MANUFACTURING CO. Nov. 14, 1964 [Nov. 7, 1963], No. 45021/64. Heading G5R. A tape feeding system wherein a tape passes between a capstan 12, Fig. 1 (not shown), and a pinch roller 14 to a transducer 22, a return capstan 15, a second transducer 24, and then passes between the capstan 12 and a further pinch roller 16, is characterized in that the capstan is divided into five zones, three zones of one diameter co-operating with one pinch roller and two zones of a different diameter co-operating with the other pinch roller to provide tape tension. As shown in Fig. 4 the capstan 45 is provided with three small diameter zones 46 and 48 which co-operate with raised zones 54 and 55 on the upstream pinch roller, and with two large diameter zones 50 which co-operate with raised zones 58 on the downstream pinch roller. In a modification, Fig. 8 (not shown), the zones 50 are of smaller diameter than the other three zones, and the upstream pinch roller is accordingly modified; the downstream pinch roller is of uniform diameter. It is explained that the known three zone capstan creates in the tape lines of tension which extend past the transducer heads and cause uneven wear on them and loss of signal due to buckling of the tape. With a five zone capstan the lines of tension do not extend as far as the transducer heads. A capstan as shown designed for one inch tape may also be used to drive half inch tape, the narrower tape then extending over only three zones.

Abstract: 1519838 Monitoring a separation process DEUTSCHE GOLD-UND SILBER SCHEIDEANSTALT 31 Oct 1975 [27 Nov 1974] 45237/75 Heading G1A In a separation apparatus using sedimentation of suspended matter, liquid flowing through outlet 6, connected to a settling tank 2 is allowed to fall freely into a funnel 11. The free falling liquid is monitored by a light source 4 - detector 5 arrangement. When the detector 5 senses that the liquid is not clear, indicating suspended matter has reached the upper part of the tank, the change in detector output actuates a sludge pump 8. This pumps away some of the sediment that has collected at the bottom of the settling tank 2. The liquid to be separated is introduced into the tank 2 through a feed pipe 9 at a flow-rate slow enough not to hinder the sedimentation process.

Source 13, such as A.C. or interrupted D.C. is supplied via RF filter, transformer 11 and a voltage doubling circuit 15-17, 19, 22 to charge the condensers until the trigger gap 25 breaks down to connect the condensers 21, 31 in series with the primary winding 35 of a step up transformer 28 and the control gap 36 which also conducts. The output voltage generated at secondary winding 27 causes an arc across the igniter plug 29 and the capacitor 20 then discharges through the trigger gap 25, winding 27 and through the pre-formed arc of the igniter gap 29. The voltage across the condensers 20, 31 then falls and the gaps 25, 36 are deionized and the cycle is repeated. The ignition spark gap 29 may be that of a jet or gas turbine engine. The diodes 16, 19 are protected against damage by limiting resistors 21, 22. The voltage doubling circuit may be replaced by a half wave rectifier. The transformer 11 may also be powered by a solid state oscillator, Specification 1330505 is referred to.
