Abstract: 1,201,586. Electrotherapeutic apparatus. DY NAPOWER SYSTEMS CORP OF CALIFORNIA. 22 Jan., 1969 [15 Feb., 1968], No. 3560/69. Heading A5R. Electrotherapeutic apparatus includes a power radiating head 10 having means for the transmission of high frequency radiation including coupled primary and secondary coils, 12 and 13, and a capacitor 14 connected to the secondary coil to form a tank circuit tuned to a predetermined high frequency, input means 18 to supply pulses of said frequency, a network 25 and transmission line coupled between the input means 18 and primary coil 12, the network having a variable impedance element and means including a servo loop apparently responsive to patient induced detuning of the circuit to vary the impedance of the element. The apparatus is generally similar to that described in Specification 1,150,524, except that the variable condenser 27 is not adjusted manually, but by an electric motor 73 controlled by the feed-back from an inductance 71 in the head 10 through a servo-loop 70. The loop 70 comprises a pair of band-pass filters 76, 77 feeding a differential amplifier of which the output is fed to the motor 73. The filters are each tuned to a band one on either side of the predetermined frequency of the main circuit so that de-tuning caused by the presence of the patient is picked up by the inductance 71 and the motor 73 is energised to adjust the condenser 27 in such a direction as to restore the system to its original tuning.

Abstract: 1,219,792. Statistical apparatus. A. C. NIELSEN CO. 24 Jan., 1968 [10 May, 1967], No. 3807/68. Heading G4M. Means for deriving statistical information about the use of a plurality of remote, e.g. T.V. sets, comprises a plurality of sections of magnetic recorded tape joined together into a continuous length, and a set of punched record cards, each card relating to a corresponding section of tape, the cards being arranged in the same order as the sections of tape, and both the tape and cards being adapted to be fed together into a computer. Each section of recorded tape is obtained from a tape recorder associated with an electric clock and located in a selected dwelling in operative relationship with, e.g., a T.V. receiver. Magnetic tape from a supply reel is passed over a recording head by the clock drive and receives timing marks and coded indications of stationselector settings. Periodically, the occupant of the dwelling is induced to operate a tape-cutting knob, remove a take-up spool accommodating the recorded tape, and send it by post, together with name, address, date and time, to a collection centre. Here, as the tape sections are spliced together, the additional data is entered on punched cards which are kept in the same order. The tape recorder may have an auxiliary clock movement so that recording continues during power failures and records of such failures are secured.

While in heat-exchanger 11 the water is heated by steam withdrawn from chamber 10 and compressed by compressor 12, the compression ratio not exceeding 1,25.  Non-condensible gases are sucked out of condensers 21-31 and from the condensing side of heat-exchanger 11 by steam-ejector 40 through line 42.  The exhaust steam discharged from ejector 40 and from turbines 14 and 18, which actuate compressor 12 and pump 16 respectively, is used to heat the water flowing through heatexchanger 50.  A small fraction of the water circulating through pump 16 is passed through valved line 84 to flash chamber 28.  The residue from flash chamber 28 is introduced into flash chamber 26. The residue passes through chambers 24, 22 and 20, and is discharged by pump 102.  The condensate from heat-exchanger 11 is passed through line 32 to condenser 29 where it mixes with the distillate from chamber 28 as well as that from condenser 31.  The distillate flows through condensers 27, 25, 23, 21, and the product-i.e. distilled water-is withdrawn from the system by pump 100.

Abstract: 1,010,592. Forming special furnace atmospheres; heat treatment furnaces. EAST MIDLAND GAS BOARD. May 3, 1962 [Feb. 3, 1961], No. 4265/61. Heading F4B. Combustible medium is introduced into the work chamber of a heat treatment furnace and induced by an air or oxygen jet into a combustion space unexposed to the interior of the work chamber but within the said chamber. A heattreatment furnace, Fig. 1, is partly heated by the incomplete combustion of fluid fuel from burners 17 in a space 16 below the hearth, and the combustion is completed in radiant tubes 18, into which the partially burnt gases forming a protective atmosphere in treatment chamber are drawn together with air and/or oxygen from nozzles 20. The gas flows and pressures within the tubes 18 and the heat treatment chamber are maintained at such values that no oxidizing agents seep into the chamber. The furnace may be heated up by supplying sufficient air to the burners 17 to complete combustion within the space 16 and the treatment chamber, or completely unburnt gas may be supplied to form the protective atmosphere. In another embodiment, a burner at the charging end of a furnace with a conveyer carrying material to fall into a quench bath at the other end provides a protective atmosphere of incompletely burnt fuel, the combustion being completed in radiant tubes arranged above and below the upper run of the conveyer. In a two-section normalizing furnace, Figs. 4 and 6, burners 56 supply fuel and air for partial combustion in passages 54 leading to outlets 55 in the ridged hearth, and combustion is completed in radiant tubes 60 leading to a flue 48 common to both sections. A soaking pit is heated by partial combustion of fuel and air from burners near the furnace crown, and radiant tubes extend from near the bottom of the furnace, passing out through the walls to a ring flue arranged below the burners. Further fuel may be supplied to the radiant tubes, or supplementary electrical heating may be provided.

Title: Process for obtaining pure zinc oxide
IPC: C22B19/04
Filed: 1934-02-09
Abstract: In the production of zinc oxide from materials containing zinc and lead such as roasted zinc ores or galvanization or foundry residues, carbon monoxide is maintained under pressure in the retorts in which the materials are treated to volatilize the zinc. Preferably the retorts have a burner orifice of smaller cross-section than that of the inlet orifice for the carbon monoxide gas.  In an example, galvanization residues freed from ammonium chloride and containing 5 per cent of lead are treated together with a reducing agent in a retort to which carbon monoxide is supplied and in which an excess pressure of 15 m.m. is maintained.  The temperature of the retort is maintained constant at 1200 DEG  C., and the zinc oxide obtained contains only 0,3 per cent of lead.
