Title: Improvements in or relating to the defrosting of refrigerating apparatus
IPC: F25D21/00
Filed: 1952-06-10
Abstract: 717,078. Refrigerating. HERON, A. G. Sept. 7, 1953 [June 10, 1952], No. 14565/52. Class 29 [Also in Group XI] An evaporator 1 is defrosted by an electric cable 2 comprising a central conductor 2b surrounded by a refractory insulating medium 2c such as magnesium oxide and a metallic sheath 2d such as tinned copper. The cables may be soldered, welded or clipped by clips 2a to the evaporator tubes. It may extend longitudinally of the evaporator or may be wound spirally thereon. In the latter case, it may have the current passed through it as it is being applied so that, on cooling, it contracts strongly on to the evaporator. Its expansion during defrosting helps the breaking off of the ice and may also actuate a switch terminating the defrosting. In a plate type evaporator, the cable is applied to the plate near the evaporator conduits. In a finned evaporator, the cable passes through holes or slots in the fins so as to lie against the evaporator. The defrosting may be initiated by the thickness of the ice engaging a pressure-actuating switch or by a time control; the defrosting may be ended by a time control, by the abovementioned movement of the cable, or by the temperature or pressure of the evaporator. The electric control circuits are described. The defrost melt water falls on to a mesh grid incorporating a further length of the cable so that, during defrosting, the melt water is evaporated.

Title: Method and apparatus for the treatment of effluents containing  in particular heavy metals
IPC: C02F1/52
Filed: 1973-03-27
Abstract: 1434594 Removal of metal ions from effluents SOC EPAP 27 March 1973 [31 March 1972] 14660/73 Heading C1C [Also in Division C7] Metal ions are removed from effluents by forming a treatment bath comprising a mixture of a metal in particulate form which is more electropositive than the metal to be removed, sand particles and the effluent so that the metal to be removed precipitates on the more electropositive metal particles, and bubbling gas through the bath to produce an abrasive action between the sand and the more electropositive metal particles thereby to detach the metal to be removed therefrom so that it can readily be separated from the effluent. In particular the processing may be applied to the waste waters of electroplating works and the recovery of copper from effluents containing copper sulphate, but it may also be applied to the recovery of copper from other effluents and to the recovery of other metals such as cadmium, palladium, lead and tin. If the metal bed is of iron particles and air under pressure is used for agitation the air also has the effect of causing ferrous ions to pass to the ferric state. This oxidation may also be achieved with javelle water or monopersulphuric acid. If the metal bed is of aluminium or zinc particles the treatment bath may also include an acid or basic agent to activate the metal by production of nascent hydrogen thereon. Aluminium may also be activated by traces of salts of mercury. The metal bed may also be activated by passing a continuous electric current through the particles. In a suitable apparatus for effecting the process the gas is blown upwardly through a perforated base-plate into the bed and when this occurs the mixture flows from the reaction zone over a partition into a decanting zone from which at least some of the decanted mixture returns through openings in the lower part of the partition into the reaction zone. Particles of iron drawn out with the effluent may be removed by an electromagnet. The hydroxide of the more electropositive metal may be precipitated in a second decanting basin. The treated effluent may be completely or partially recycled. Reference is also made to the use of the method with chromate- and cyanide-containing effluents, and effluents containing nitrates may be detoxified, the nitrates being converted to amines. Six figures illustrate various forms of suitable apparatus and complete treatment cycle and a graph showing degrees of precipitation of various metals in dilute aqueous environments according to pH is also provided.

Title: Spark plug shells and a method for their manufacture
IPC: H01T21/02
Filed: 1963-04-11
Abstract: A spark plug shell 12, Fig. 4, is made by extruding a sintered compact of metal powder. Nickel powder 2, Fig. 1, admixed with a lubricant such as hydrogenated cottonseed oil or zinc stearate, is first lightly pressed between punches 4, 5 in a die 3. A quantity of iron powder 6 admixed with cottonseed oil is then compacted at 25-50 tons per square inch on top of the nickel 2, Fig. 2.  The compacted block is removed from die 3 and sintered in an atmosphere of dissociated ammonia or hydrogen using a slow heating rate of 200  DEG F. in 5 minutes up to 1000  DEG F. and then rapid heating <PICT:0957940/C3/1> <PICT:0957940/C3/2> <PICT:0957940/C3/3> to between 1900 and 2300  DEG F. which is maintained for one hour. Cooling occurs in a non-oxidizing atmosphere.  The sintered billet is then further compressed at 50 tons per square inch, re-heated to 2300 DEG F. for one hour, coated with phosphate or molybdenum sulphide and extruded in a die 8, Fig. 4, by a punch 10.  An ejector 11 removes the cup-shaped workpiece which has a lower nickel portion 14 for forming the earth electrode 18, Fig. 5 (not shown), and an upper iron portion 15.  The extruded shell is then cleaned, machined and threaded. In another embodiment, the sintered workpiece may have a core of sintered copper, Fig. 8 (not shown), to provide a copper lining on the plug casing, and in another embodiment, Figs. 6, 7 (not shown), the sintered workpiece may comprise a body portion of iron with a copper core. This core may be of sintered powder or may be a compacted slug of copper. After extrusion a nickel earth-electrode is welded to the shell. In a further embodiment, Fig. 10 (not shown), the sintered workpiece consists of a body of iron powder with a hollow lining of silver powder which forms a silver lining on the electrode body, Fig. 11 (not shown); a base of nickel powder may also be provided to form the earth electrode.

A temperature-responsive control device for maintaining a liquid 14, especially a low boiling point liquid such as liquid air, at a substantially constant level in a vessel 9 by periodically replenishing the liquid from a reservoir 12 comprises a bellows 1 carrying a valve 6 seating on the end of a tube 5 connected by a pipe 10 to the vapour space in the reservoir, the interior of the bellows communicating with a thin-walled tubular feeler 3 extending downwardly into the vessel 9 and being closed at its lower end. The feeler and bellows are charged underpressure with a liquid which boils at a temperature slightly above the temperature of the liquid 14, for example, liquefied methane when the liquid 14 is liquid air, so that the filling medium partially condenses when the end of the feeler is immersed in the liquid 14 and evaporates when the level falls below the feeler. When the charge liquid condenses the bellows 1 contracts opening the valve 6 to allow the vapour in the reservoir to vent to atmosphere. When the level in the vessel 9 falls below the feeler the liquid evaporates and the valve 6 closes, the liquid in the reservoir then discharging into the vessel 9 under its own vapour pressure until the level again reaches the preset value. To increase the sensitivity of the device an electric heater may be provided for the feeler 3 the heater being energized to evaporate the charge liquid quickly when the level drops below the feeler. In a further modification the bellows movement opens or closes an electrical circuit including a solenoid valve, a process timing switch or a warning signal device.
