Patent GB-1128013-A (GB)
Title: Battery charging systems for road vehicles
Inventor: WRIGHT MAURICE JAMES
IPC: H02H9/04
Filed: 1964-12-09
Abstract: 1,128,013. Automatic voltage control. JOSEPH LUCAS (INDUSTRIES) Ltd. Dec. 1, 1965 [Dec. 9, 1964], No. 50042/64. Heading G3R. [Also in Division H2] A battery charging system has a currentresponsive circuit-breaker or fuse 34 in series with the control circuit of an alternator 21 and a voltage-responsive variable resistance device 37 across the control circuit. When over-voltage occurs, the device 37 conducts sufficient current to protect the components until the circuit breaker is operated or the fuse is blown. The device 37 may be a zener diode, a four layer diode or a non-linear resistance. The figure shows a vehicle battery charging circuit comprising the alternator 21 with a rectifier bridge circuit having diodes 25 and thyristors 23 having their gates connected to the secondary winding 43 of a transformer 39. The transformer has a primary winding 38 and a feedback winding 42, and forms with a transistor 41 an oscillator to render the thyristors conductive. When the voltage between lines 24, 26 reaches a predetermined value, a Zener diode 32 breaks down to render a transistor 33 conductive, which in turn renders the transistor 41 non conductive so that at the end of their conducting periods, the thyristors do not switch on. The voltage between the lines 24, 26 falls and when a capacitor 31 has discharged sufficiently the Zener diode 32 cuts off, so that the oscillator operates again. Should a fault occur, resulting in an excessively high voltage, a Zener diode 37 breaks down and a fuse 34 in series with the primary winding 38 blows and so renders the oscillator inoperative.

Title: An improved method for dyeing cellulose with acidic or basic dyes
IPC: D06P1/651
Filed: 1963-12-20
Abstract: The invention provides a method of dyeing cellulose with acid or basic dyes having no substantial affinity for cellulose in which said dye is applied to the cellulose in the presence of water, formaldehyde and a metallic salt which is a Lewis acid in the solid state followed by drying and curing.  The drying operation is effected at temperatures below 110 DEG C. and the curing above 110 DEG C.  The fabric may be treated with an aqueous dyebath first, followed by a bath containing the formaldehyde and metallic salt (which is the curing agent) or alternatively separate solutions of all three reagents may be used.  pH of the bath ranges from 1 to 10 preferably 5-10, the concentration of formaldehyde has wide limits, the Lewis acids used are defined and are bivalent metals of group II being the salts of strong monoboric acids especially salts of calcium, magnesium, strontium, borium and zinc.  The cellulosic material may be natural or regenerated and may be mixed with other synthetic materials but preferably 35% of cellulose is present.

Title: Ion exchange resin regeneration
IPC: B01J49/00
Filed: 1970-10-22
Abstract: 1331273 Regenerating ion-exchange resin ECODYNE CORP 22 Oct 1970 [24 Oct 1969] 50316/70 Heading B1J Ion-exchange resin is regenerated in a column 10 by passing regenerant into the column through an inlet 22 and rinse water through an inlet 30 below the inlet 22. The water forms a gap in the resin as shown and at the end of a regeneration period, the supply of regenerant and water is cut off and a valve 38 in a drain-pipe 36 is opened to de-pressurise the column so that the gap in the resin is filled and a new batch of exhausted resin is fed from a hopper 12 through a non-return valve 16. Rinse water is then again fed through the inlet 30 and carries upwardly any regenerant entrained in the resin. After a time which is sufficient to allow the lowest level ofentrained regenerant to rise to the level of the inlet 22, regenerant is again fed through that inlet (and leaves the column with the water through an outlet 34). Deferring the supply of regenerant in this way prevents the resin from being subjected to an over-dose of regenerant. As the flow of rinse water commences, regenerated and rinsed resin is forced out of the column through a pipe 20 into a metering hopper. The valve 38, the valves 32 and 24 controlling the supply of rinse water and regenerant and a valve 28 controlling the supply of dilution water may be controlled automatically by device 40. If desired, rinse water may be supplied for a while after the supply of regenerant has been stopped to carry the lowest level of entrained regenerant up to a level C before the column is de-pressurized to admit further exhausted resin. The method is particularly applicable to the regeneration of cation exchange resin using sulphuric acid.

Abstract: 1,035,848. Torque converters. M. T. E. GIRI DE TERAMALA, and L. P. F. L. GIRI DE TERAMALA. Sept. 23, 1964 [Dec. 20, 1963], No. 50505/63. Heading F2C. In a hydrodynamic torque converter comprising a vaned impeller, a vaned turbine 2, and a vaned reactor which can be held against backward rotation, the outlet (inner) ends of the turbine vanes are directed backwards relative to the direction of rotation of the turbine, at an angle relative to a plane containing the axis of rotation Z of the turbine which is greater at the largest radius A of the outlet than at the smallest radius C thereof, so that the width X between adjacent vanes is substantially constant across the radial extent of the outlet. This is stated to enhance the uniform flow of liquid from the turbine outlet. The turbine vanes have bulbous or thickened inlet edges whose width is at least one third of the vane pitch at the inlet of the turbine.

The compression of the spring is effected by a collet grip 17 which is moved by flywheel 15 so as to grip the upper end of rod 6, release being effected by means 19 after suitable raising of cap 21 which is fixed to rod 6. The output from photoreceiver 13 is a train of pulses, the period and number thereof being proportional to the velocity and displacement respectively of the piston 5. A chosen reference pulse generator 30k-30p and the output from photoreceiver together generate from key switch 29 a bundle of pulses the number of which being proportional to the reciprocal of the velocity of the piston 5, this number being counted by counter 32. Minimum 34 and maximum 35 circuits are employed so as to check that the appropriate pulse generator 30k-30p is employed, automatic switching to a higher or lower frequency generator resulting if required. A digital to analog converter 39, log converter 40 and adder 41 further process the signal before recorder 24. Charging of the pulse frequency generates via a digital analog converter 42 a necessary shift in recorder 24. The output from photoreceiver 13 is also fed to a counter 25, a digital to analog converter 43 and log converter 44 providing the necessary processing.
