Patent GB-1188148-A (GB)
Title: Line Following Apparatus
Inventor: MCPHERSON JAMES
IPC: B23K7/00
Filed: 1967-09-08
Abstract: 1,188,148. Welding and cutting by fusion. DISTRIBUTION TRANSFORMERS Ltd. 4 Sept., 1968 [8 Sept., 1967], No. 41151/67. Headings B3R and B3V. [Also in Division G3] In a line following system where lines cross one another, a surface for bearing the line to be followed has relatively movable areas whereby the crossing parts of the line can be spaced apart on one of the areas, and the second crossing part can be moved into an appropriate position after the first crossing part has been followed. The junction where the two relatively movable areas join is preferably arranged approximately at right angles to the direction of the line. A means may be provided for moving one surface while the line on the other surface is being followed, and for initiating the movement in response to detection as the follower is over the other surface. The arrangement may be used particularly for welding or flame cutting equipment. For example a pattern for welding elliptical sectioned transformer cooler tubes may be divided into two parts 13, 18, one part 13 being fixed and carrying the upper halves of the ellipses, and the lower part 18 being slidable horizontally in which the lower part of the ellipses, shown in full lines, are divided into two and displaced laterally. When the follower is on the upper part of the ellipse, say at point 32 a cam operated switch operates an hydraulic servo to move the surface 18 to the right so that the line 29 takes up the position shown at 29<SP>1</SP>. When the follower reaches point 34, the surface 18 is moved back to its original position. The arrangement provides overlapping welds at junctions which are stated to be preferable to overlapping welds occurring at right angles to each other.

The transistor 45 has the same base-emitter characteristics as the transistors 27 to compensate the output voltage at 23 for the base-emitter voltage drop across the conductive transistor, or a p-n junction diode may be used instead of transistor 45.

Abstract: 1466472 Transferring liquids DIESSEL GmbH & CO 30 Sept 1974 [27 Oct 1973] 42318/74 Heading A4T Apparatus for transferring measured quantities e.g. of milk from a tanker 1 to a stationary tank 2 comprises a centrifugal pump 10, an air separator 9, a further centrifugal pump 12 and a volume measuring device 16. In operation milk, &c., is  pumped through the system by the pump 10, flowing largely through a main line 17 with a non- return valve 18 and partly through a by-pass 14 including the pump 12. At the end of a delivery, when milk ceases to pass through the pump 10, the pump 10 ceases to exert a discharging pressure on the liquid in the separator 9, this liquid continuing to be discharged by the pump 12. When the level in the separator 9 reaches a predetermined residual figure, a float 28 actuates switch means 27 to stop the pump 12. For cleaning, the separator 9 is emptied by means of the pump 12, an inlet hose 8 is transferred to a cleaning fluid supply and the pump 10 is started. A time-switch controlled reversing valve 21 directs the fluid into the tank 9 first via a main line 11 and then via a branch 22 and nozzles 24, the fluid collecting in the separator 9 until rising of the float 28 causes the pump 12 to become active to ensure cleaning of the by-pass 14 as well as the line 17.

Title: Improvements in or relating to electrolytic cells
IPC: C25B15/00
Filed: 1965-10-11
Abstract: <PICT:1121842/C6-C7/1> The cathode of an electrolytic cell is protected from corrosion, after the electric current has been interrupted, by introducing a protective fluid on to the cathode so that corrosive agents in the electrolyte in the zone between the anode and cathode of the cell are prevented from reacting with the cathode and corroding it. The fluid may be inert or reactive with the corrosive chemical and may be a liquid or gas, e.g. N2 or air.  For example, the Hg cathode of a cell for producing Cl2 from brine is protected from the corrosive action of Cl2 dissolved in the brine by pumping a fluid through passageways in a graphite anode 1 and on to the Hg cathode 2, the fluid being supplied through a tube 12, a horizontal slot in the anode 1 and vertical ducts 22.  The fluid may be an aqueous solution of bi-sulphite, sulphurous acid or thiosulphate or may comprise bubbles of SO2 either alone or mixed with an inert gas. Fig. 3 (not shown) illustrates a Hg-cathode brine cell with horizontal foraminous metal anodes (33) suspended from metal stems (34), the active surfaces of the anodes being thin coatings of noble metal, e.g. Pt, Ir, Rh or noble metal alloy. Fluid is supplied to the cathode through the foraminous anodes by horizontal perforated pipes (35) just above the anodes, thereby protecting the anodes as well as the cathodes.

Filed: 1963-11-01
Abstract: Industrial waste water containing zinc ions sulphur-containing compounds and colloidal or suspended organic material is electrolyzed at a current density of 0.5 to 8 amps/dm2 whereby the colloidal material coagulates, absorbs zinc ions, and rises to the surface, and the thus-formed floc is removed from the surface of the water. Typically the water contains zinc sulphate, sodium sulphate, hydrogen sulphide carbon disulphide and cellulosic compounds, and may be waste water of pH4 from viscose rayon production in which case its pH may be raised to 5.5 to 6 or even 6.8 before electrolytic treatment.  The treatment may be batchwise and the cell may employ vertical rod-like electrodes, e.g. of stainless steel or graphite for the cathodes and of cast iron or steel for the anodes, arranged in chequer board formation with a distance of 20 mms. between them, or cast iron plates separated by 10 to 15 mms. may be used.  The electrode spacings may be arranged to increase gradually from the inlet to the outlet of the cell, the water being passed continuously through it.

Abstract: 867,936. Milling-machines. CINCINNATI MILLING MACHINE CO. Dec. 24, 1959 [Jan. 7, 1959], No. 43857/59. Class 83 (3). A machine tool comprises means 33 for applying an upward pressure to a verticallymovable member 15 to more than counterbalance its weight and means for applying an equal downward pressure on the member when it is desired to move the member downwardly. Thd cutter slide 15 is adjustable vertically by a hand-crank 20 rotating a nut 24. The work is carried on a slide 12. The counter-balancing device comprises a piston 33 and a hollow rod 30 connected to the slide. When the crank 20 is rotated to lower the slide, the pressure beneath the piston 33 is increased, due to the line 47, Fig. 2, being connected to a resistance 46. The pressure drop across the resistance causes a valve 49 to be actuated to connect the pressure line 45 to the upper end of the piston 33. In a second embodiment, the resistance is constituted by a restricted bore in a modification of the valve 49.

Butane is converted to an anti-knock octane or octene, or heptenes are produced from isobutene by exposure to heat and nuclear radiation generated by a heterogeneous reactor. The reactor is mounted in an undergound chamber to which the organic fluids are supplied through a borehole. The fluids also act to the reactor reflector and moderator and the heat and radiation process takes place throughout the entire underground installation and not solely at the reactor. Control is effected by adjustment of the rate of fluid flow or fluid density. The intensity of the nuclear radiation applied to the hydrocarbon may be increased by the addition of copper sulphate. In this case, both the copper and sulphur atoms are rendered radio-active in the core and irradiate the hydrocarbon in the reflector zones. The reactor fuel is in the form of spheres with a protective coating and a control is effected by adjusting the suspension of the spheres in the upward fluid flow. Ring-shaped elements may also be used which change shape during temperature changes to provide a further control.
