Patent GB-247919-A (GB)
Title: Improvements in or relating to carburetters
IPC: F02M3/09
Filed: 1925-11-23
Abstract: 247,919. Joly, G. F. C. Feb. 17, 1925, [Convention date]. Addition to 244,734. Void [Published under Sect. 91 of the Acts]. Manually-actuated multiple-way valves.-Specifications 244,734 and 245,423, [both in Class 7 (iii), Internal-combustion engines, Carburetting- apparatus &c. for], describe methods of clearing the fuel nozzle of obstruction by isolating the nozzle from the float chamber and at the same time connecting it with a source of suction, e.g. the induction pipe or a separate pump whereby a backward suction through the nozzle is created, and the invention consists in applying the methods to existing carburettors. The valve h, Fig. 1, for isolating the nozzle c and connecting it to the suction source g<2>, g<1> is located in the passage between the float chamber a and the nozzle, the parts b, b<1> of said passage being at different levels. The valve is actuated by a rod h' in a chamber a<1> the upper end of which is above the level in the float chamber. To clear the nozzle, the valve is rotated to bring the channels b<1>, g' into communication and by thus rotating the valve, an additional supply of fuel may also be obtained at starting. In the application to a carburettor with two main and two compensating nozzles, the float chamber a, Fig. 3, feeds the nozzles through passages b across which, according to the invention, are screwed hollow members D, E which serve as bolts to secure a casting H which contains the isolating valve h. This valve is actuated by a rod h<1> which carries a second valve h<2> to control a channel H<1> leading from valve h to the suction source g<1>. Normally the fuel from the float chamber passes to the nozzles c by way of channels b, b<2>, b<3>, valve h and channels b<4>, b<5>. To clear the nozzles, the valve is turned to connect the channels b<4>, H<1>. The upper end of the rod h' projects from the casting H at a point above the normal fuel level. In a modification, Fig. 7, the isolating valve comprises a tubular part h mounted on a rod h<2> and provided at one end with a cone and at the other with a flange h<1> faced with fibre or other plastic material and adapted to seat at i<1> on a ring i. The passage leading to the nozzle is shown at b<1> and to the source of suction at g. The valve is loaded by a spring h<3> and may be moved from one seat to the other by actuating the rod h<2> by a lever j, k mounted on an adjustable screwed ring m.

Title: Automatic signalling-apparatus for street-crossings and the like
IPC: E01F11/00
Filed: 1945-11-07
Abstract: 600,435. Road signals for controlling traffic. NAERBO, D. Nov. 7, 1945, No. 29619. [Class 118 (ii)] A hydraulic traffic signal system comprises a padoperated piston and cylinder in communication with a second cylinder whose piston has attached to it a switch-member adapted to close circuits for a " clear " and a "stop '' signal. A hinged plate 1 (Fig. 1) fitted into the roadway is pressed in an upward direction by a spring 3. Depression of this plate by a passing vehicle forces down a piston 4, against the pressure of springs 24, to impel liquid along a pipe 6 and past a non-return valve 9 to raise a second piston 8 against the pressure of a return spring 25. On an extension rod 12 (Fig. 2) of this second piston 8 is an electrically-insulated cross-piece 13 on which are pivoted at 29, 29<SP>1</SP> two arms 14, 14<SP>1</SP>, carrying contact rollers 16, 16<SP>1</SP>, which are urged outwards by a spring 15 against fixed contact members 17, 18, 19 and 17', 18<SP>1</SP>, 19<SP>1</SP>. As the piston 8 rises, the contact rollers 16, 16<SP>1</SP> leave contacts 17, 17<SP>1</SP>, extinguishing a " clear " signal 22 and connect contacts 19, 19<SP>1</SP> to light a " stop " signal 23. When the actuating vehicle leaves the plate 1, the springs 24, 25 begin to restore the pistons 4, 8 to normal. The return of piston 8 and its contact rollers 16, 16<SP>1</SP>, however, is slowed down since the operating liquid has to byepass the non-return valve 9 by means of a small adjustable outlet 10. Thus, the " stop " signal 23 remains alight for a predetermined time. As the piston 8 and contact rollers 16, 16<SP>1</SP> continue to fall, they leave contacts 19, 19<SP>1</SP> and the " stop " circuit is momentarily broken, contacts 18, 18<SP>1</SP> momentarily re-establish it, it is again broken, and contacts 17, 17<SP>1</SP> then establish the " clear " circuit.

Patent GB-846498-A (GB)
Title: Improvements in or relating to the quantitative determination of low concentrations of volatile compound in water or aqueous solutions
IPC: G01N25/14
Filed: 1957-09-20
Abstract: For the quantitative determination of carbon <PICT:0846498/III/1> dioxide in boiler-feed water, a constant measured flow of the water to be tested is passed through a pipe 11 to a tube 12 containing a bed of cation exchange resin in the hydrogen form to remove volatile cations such as ammonium ions which would interfere with the measurement of the carbon dioxide concentration and replace them by hydrogen ions.  The water stream then passes through an electrically heated metal tube 13, the electrical heating being adjusted to raise the water temperature to between 95 DEG  and 99 DEG C., enters the distillation column 14, of which the stripping section 15 is designed to reduce the carbon dioxide concentration of the water leaving the electrically heated boiler to about 1/1,000th of that in the water under test.  The electrical heating of the boiler section 16 is adjusted to convert to steam approximately a 1/25th part of the flow of the water entering the distillation column.  This steam passes up the stripping section 15 and removes the carbon dioxide from the water, with which the steam is in contact as it descends the column, into the rectification section 17, of the column where the steam is contacted with condensate flowing down the section and thus the steam leaving the top of this section is enriched in carbon dioxide.  This stream of steam and carbon dioxide flows up the pipe 18 and downward through a condenser 19 consisting of a small vertical water-cooled tube.  A constant and measured stream of hydrogen as sweep gas is passed into the top of the stripping section 15 of the distillation column through inlet 20.  The carbon dioxide is distributed between the condensate formed in the condenser and the sweep gas.  Below the condenser the gas and condensate pass through a tube 21 in which they are brought into intimate contact and come to an approach to equilibrium with each other.  A small constant stream of the condensate is passed through a cell 22 containing electrodes which enable the electrical resistance of the condensate to be measured. On leaving cell 22 the condensate is returned to the top of the rectification section 17 of the distillation column 14.  The sweep gas is vented to the air through outlet 23 and carries with it almost all the carbon dioxide which enters the apparatus in the water.  The carbon dioxide content of the water under test can be readily calculated from the measured electrical conductivity of the condensate.

Title: Control of aerobic biological growth in activated carbon waste water treatment
IPC: C02F3/06
Filed: 1973-06-22
Abstract: 1439401 Activated carbon waste water treatment EXXON RESEARCH & ENG CO 22 June 1973 [28 June 1972] 29695/73 Heading C1C In a process for removing suspended and dissolved organic contaminants from waste water wherein the waste water is pretreated to remove suspended contaminants from the bed and thereafter passed through at least one bed of activated carbon to remove dissolved organic contaminants, oxygen is added to the bed of activated carbon in an amount in the range of 0À09 to 0À15 lb of oxygen per lb of COD contaminants to be removed. Preferably the waste water is passed upwardly through the carbon bed. The activated carbon bed may be periodically backwashed by passing effluent from the pretreatment step or effluent from the carbon treatment step upwardly through the bed at a sufficient rate to reduce the amount of biological growth accumulated on the carbon. In a modification of the invention, the carbon bed is backwashed as above, the bed is intermittently contacted during backwashing with a gaseous stream containing oxygen and the amount of oxygen added to the bed during treatment is reduced to 0À05 to 0À12 lb per lb of COD contaminants to be removed. The carbon is preferably activated fluid coke and the oxygen may be added directly to the bed or to the waste water stream entering the bed. The pretreatment of the waste water to remove suspended solids and oils may comprise chemical coagulation followed by dissolved air flotation, solids contact clarification or dual-media (e.g. anthracite and sand) or multi-media filtration. Coagulants may be polymeric or preferably an activated clay, such as a sodium montmorillonite clay in combination with a cationic agent such as an amine or glycol, is used. The use of alum tends to produce fouling of the bed.
