Abstract: 1402229 Electrolytic treatment of cyanide waste MITSUBISHI PETROCHEMICAL CO Ltd 12 Dec 1973 [20 Dec 1972(2)] 57533/73 Heading C7B Cyanide-containing waste is purified by a combination of electrolytic oxidation and electrodialysis by passing a portion thereof serially through a cathode chamber 6 bounded by a cationexchange (CX) membrane 4, an anode chamber 5 bounded by an anion exchange (AX) membrane 3 and recirculating to storage 9; simultaneously passing another portion thereof through parallel concentration chambers 8 bounded by alternate AX and CX membranes and recirculating to storage 9; and simultaneously passing an alkali or alkaline earth metal chloride solution through parallel dilution chambers 7 bounded by alternate AX and CX membranes and recirculating to storage 10; chambers 7 and 8 and the AX and CX membranes being arranged alternately between the cathode and anode chambers with a dilution chamber being directly adjacent the cathode and anode chambers. When the CN content reaches a sufficiently low level, the metal chloride solution may be discharged, the partially purified CN waste now rich - in metal chloride transferred to storage 10 and fresh waste added at 9. In an alternative embodiment, two cells as shown in Fig. 1 are used in series, the first portion of the CN waste passing from the cathode chamber of one cell to the anode chamber of the other, and the second portion thereof and the chloride solution passing sequentially through the parallel other chambers of the two cells. In this case the electrodes of one cell are both bounded by AX membranes and of the other by CX membranes, whereby, when the CN concentration falls low enough the chloride solution may be discharged and replaced by fresh CN waste and the partially purified CN waste now rich in metal chloride becomes the new chloride solution by reversing the electric polarity of the system. The CN solution may contain K 4  (or Na 4 ) Fe(CN) 6 , K 2 Ni(CN) 4 , NaCN, or K 2 Cu(CN) 3 . The chloride may be NaCl. Treatment at 50- 100V for 1-3 hours is specified. The CN is removed from the initial solution by dialysis and is ultimately destroyed by electrolytic and chemical oxidation, the latter using electrolytically generated Cl 2 .

Abstract: 1406859 Reclaiming waterlogged cable WESTERN ELECTRIC CO Inc 15 Dec 1972 [15 Dec 1971] 58020/72 Heading H2C Liquid is purged from the interior voids of an elongate core member, e.g. a multi-pair sheathed plastics insulated telephone cable in which the voids are between the interstices of the pairs, by introducing a purging agent into the member, which purging agent when introduced into the member has an initial viscosity of less than 100 c.p.s. at 35‹ to 90‹ F. and comprises a solvent containing a first component comprising an isocyanate prepolymer and a second component comprising a polyol, the solvent also containing a catalyst for catalysing a cross-linking gelling reaction between the solvent and the components to form a cross-linked network which resists further entry of the liquid into the member. The first component is preferably a prepolymer derived from toluene diisocyanate or diphenylmethane diisocyanate and castor oil or a hydroxyl terminated polybutadiene and the second component is preferably a hydroxyl terminated polybutadiene. A prepurgant may be pumped into the voids prior to the components of the purging agent. The prepurgant must be miscible with the liquid in the voids and the components and may be a low molecular weight polypropylene glycol, polyethylene glycol or methyl ethyl ketone. The process is particularly useful in permanently purging water which has seeped into telephone cables.

Title: Improvements relating to hydraulic power transmission systems
Inventor: MARSHALL JOHN STEPHEN

Filed: 1968-12-10
Abstract: 1285718 Hydrostatic transmission RUBERY OWEN & CO Ltd 5 Dec 1969 [10 Dec 1968] 58619/68 Heading F2D In a vehicle hydrostatic transmission, e.g. for a straddle carrier for handling large containers, a first pressure relief valve limits maximum pressure during normal operation, and a second pressure relief valve limits the pressure to a lower predetermined valve during overrun when the motor acts as a pump. As shown, the trans. mission comprises an engine-driven swash plate pump 2 and motors 28, 33 coupled to rear and front wheels 20, 30 respectively on one side of the vehicle, the whole system being duplicated for the other side. The manually controlled pump 2 drives the motors through delivery and return lines 26, 27 and a three-position reversing valve 17 positioned by a solenoid operated valve 56. A main pressure relief valve 21 limits the maximum pressure, (e.g. 3000 p.s.i.), during normal operation. With the valve 17 positioned for forward travel, line 26 is the high pressure line. Should motors 28, 33 overrun, the high pressure in line 27 is relieved through the valve 17 to a line 6 containing a low pressure relief valve 7, (e.g. 100 p.s.i.), to provide gradual engine braking. Harsher braking may be obtained on overrun by moving valve 17 to its neutral position blocking lines 26, 27. Movement of valve 17 also effects movement of a mechanically linked second slide valve 42 connecting control fluid 11 from a secondary engine-driven pump 3 selectively to either one or both lines 46, 47 to slide valves 44, 45 obstructing flow from respective pilot operated relief valve 51, 52 connected by non-return valves 49, 48 to lines 27, 26. With valves 17, 42 in neutral, the slide valves 44, 45 allow valves 51, 52 to become operative to relieve pressure at a valve intermediate those of valves 21 and 7 to provide harsher braking. A slide valve 25 is manually controlled by a solenoid operated valve 55 to isolate motor 28 to drive motor 33 faster, the valve 25 then directing cooling control fluid to motor 28. Again, Fig. 6 (not shown), the valves 51, 52 may control the pressure during all overrun without having to move the valves 17, 42 by inserting a non-return valve (96) in the line 6 between the valve 7 and the discharge line 24 from the valve 17 to the line 6. Also, Figs. 2-5 (not shown), the slide valves 25, 44, 45, the non- return valves 48, 49, and the pilot relief valves 51, 52 are formed in a single block. The valve 25 comprises a spool in a bore (69) into which open four ports for the lines 26, 27, two ports from the pump 2 and two to the motor 28, and a fifth port at the end of the bore and connected to the valve 55. A parallel bore (70) contains the two pilot valves 51, 52 opening into a common chamber (84), and spring-moved one-way valves 48, 49 at opposite ends of the bore. The two slide valves 44, 45 are mounted in transverse bores opening into the bore (70).

Title: A-C Motor Speed Control System with Incremental Speed Variation.
IPC: H02P29/00
Filed: 1968-12-16
Abstract: 1,188,770. Control of A.C. motors. BORGWARNER CORP. 16 Dec., 1968 [22 Dec., 1967], No. 59729/68. Heading H2J. An induction motor is supplied from an inverter which receives energy from a rectifier connected to an A.C. source through a variable transformer. A main oscillator regulates the frequency of the inverter and is controlled by a .potentiometer linked with the variable transformer so as to maintain the volts-per-cycle ratio constant over a speed range. A modulating signal is passed to the main oscillator to effect an incremental change in motor speed, this signal being derived from a clock oscillator 31 supplying timing signals to a binary counter 33 associated with a digital-to-analogue converter 35. The output from the latter is transmitted through an operational amplifier stage to the main oscillator. Closure of switch 40 energizes relay 61 which separates contacts 62, 63, and enables a chain 51-58 to start counting the timing signals from the clock oscillator 31. Upon receipt of the first timing signal from the oscillator 31, a flip-flop 51 operates to switchoff transistor 71 and switch-on transistor 72. Resistor 100 is connected between conductors 110, 32b and a signal is applied through conductors 36a, 36b to the operational amplifier. When the next timing pulse is received, flipflop 52 is switched-on and flip-flop 51 is switchedoff whereby resistor 101 replaces the resistor 100. Thereafter, resistors 100, 101, are arranged in parallel to provide a signal of different voltage level to the operational amplifier. This action continues until the counter 33 is full, as signalled by operation of gate 58. The clock oscillator has a frequency-control potentiometer to regulate the total time to fill the counter 33. The gain of the operational amplifier is adjusted by means of a feedback resistor, thus controlling the amount of the total frequency change. In another arrangement, a variable transformer is connected between the inverter and motor, and has its voltage setting adjusted by a pilot motor associated with a volts-per-cycle regulator. The latter detects the amplitude and frequency of the motor current whereby the setting of the variable transformer is adjusted if the volts-per-cycle ratio deviates from a reference value.

A flat display panel comprises a matrix of glow discharge cells 50, and means concealing selected cells 60 which are adapted to glow to provide starting stimulus for the remaining cells. The panel comprises a glass or ceramic plate 20 between a glass viewing window 30 and a bottom plate 40 with row and column electrodes X, Y on each side of the plate 20. To prevent obstruction the upper electrodes are strips of transparent material, have apertures aligned with the cells, are offset from the cells or are in the form of thin wires. The cells are filled with Ne and/or A and interconnected to allow the passage of charged particles from cells 60 to facilitate ignition of other cells. An opaque electrode X4 covers cells 60 which are continuously energized. The panel is scanned by energizing Y electrodes in turn and applying information signals to selected X electrodes. Selected cells 60 may be actuated continuously by separate electrodes in slots in the centre plate, Fig. 5 (not shown). The selected cells may form a U or E arrangement or surround the panel.

Filed: 1970-12-17
Abstract: 1314690 Coating R C A CORPORATION 17 Dec 1970 [22 Dec 1969] 59993/70 Heading B2E A generally flat surface is coated by rotating the surface facing downwardly about an axis of rotation substantially normal to the surface, directing a stream of liquid coating material in a trajectory which contacts the rotating surface substantially tangentially and passes through the axis of rotation, continuing the rotation of the surface through at least one revolution while the stream of material contacts the surface, removing the stream of material and then draining excess coating material from the surface by continuing the rotation of the surface. As shown in Figure 1 a viewing face plate panel 21 of a cathode ray tube is supported in a holder and is slowly rotated about axis 23 A panel 21 has a pattern of polymeric dots produced on the inner surface. Axis 23 is inclined from vertical axis 35 by 30‹. A stream 37 of liquid coating material comprising aqueous suspension of colloidal graphite issues from nozzle 39 located such that the stream 37 contacts the inner window surface 27 tangentially above axis 23 so that the coating material passes after contact with the surface through the axis of rotation and then radially across the inner surface 27. The stream is continued while panel 21 is rotated at least one revolution, preferably about 1.2 revolutions to assure overlapping coverage. Stream 37 is then stopped and rotation continued while excess coating material drains off. The rotation may be increased at this point. Drying may be accelerated by applying radiant heat. The coated panel is then treated to remove the polymeric dots and overlying coating while retaining the coating material around the areas previously occupied by the dots. Other light-attenuating materials may be used for making a light-absorbing matrix, such as other forms of carbon, e.g. carbon black and acetylene black, and pigments such as ferrous oxide and manganese dioxide.
