Title: Improvements relating to gas and other fluid meters
IPC: G01F3/30
Filed: 1931-07-16
Abstract: 379,467. Gas meters. PARKINSON & COWAN (GAS METERS), Ltd., CHESHIRE, W. D., and BUTTERWORTH, E., Bell Barn Road, Birmingham. July 16, 1931, No. 20396. [Class 54]. A meter for gases or liquids comprises two cylindrical chambers a separated by a chamber b and each containing a hollow cylindrical rotor e which can rotate with slight clearance from the chamber on eccentrics g secured to a spindle h operating the counting mechanism. The rotors e carry radial vanes i which extend through apertures j in the chambers a into lower chambers k and are provided at lower ends with rollers l engaging guide slots m in the chambers. The chambers k contain a sealing liquid into which the vanes dip and preferably communicate with one another through a passage t below the chamber b. The chamber b is divided by a partition s into two compartments. Gas supplied to the compartment through an inlet connection q passes through ports o in the walls between the chambers a, b to the space on one side of each vane i thereby causing rotation of the rotor and the expulsion of the gas on the other side of the rotor through ports p to the other compartment of the chamber b, which compartment is provided with a gas outlet r. The two rotors are arranged at 180‹ apart on the spindle h so as to prevent a "dead centre " position of the meter. The rotors are balanced by weights c and may be mounted on antifriction rollers /. The vanes i may be rigidly or hingedly attached to the rotors or may each consist of two hingedly connected parts, one part being rigidly attached to the rotor. Additional gas inlet and outlet .ports o, p may be provided in the end walls of the chambers a and the meter may comprise more than two rotors operating in separate chambers. Fig. 5 shows a construction suitable for use when only a single rotor is employed in which the gas is admitted to the chamber k through an inlet pipe wand withdrawn through a pipe u. When the rotor is in its lowest position a sealing piece v on the rotor dips into the sealing liquid over the pipe wand prevents the passage of unmeasured gas. As the rotor passes into close proximity with the wall of the measuring chamber the piece v becomes unsealed.

Title: Improvements in method and means for improving blast furnace operations
IPC: G05D23/13
Filed: 1943-12-13
Abstract: 582,429. Blast furnaces. UNITED STATES STEEL CORPORATION OF DELAWARE. Dec. 13, 1943, No.20854. Convention date, June 22. [Class 72] [Also in Groups XXXV and XXXVIII] Means are provided in a blast furnace for automatically regulating the temperature of the hot air blast to compensate for fluctuations in the humidity of the cold air supply. As shown, a sample of air taken from the blower intake is passed through a chamber 9 which is kept at a constant temperature and contains a thermopile 14 the alternate junctions of which are moistened by a water spray and whose output thus depends on the humidity of the sample. Under normal conditions, the voltage developed by a thermocouple 16 in the hot air main together with a portion of the voltage developed by thermopile 14 should balance the voltage across resistor 31 and that part of a slide wire below its contact 33. A change in humidity or temperature will unbalance the voltages causing relay 20 to deflect and by closing contacts 22 or 23 cause rotor 24 to turn until the voltages are balanced again. The rotation of cam 36 by the rotor actuates control arm 45 and energises motor 18 thus closing or opening mixer valve 6 which controls the amount of cold air bye-passed round the air heater 3 and varies the temperature. The position of the cam follower controlling arm 45 and thus the setting of valve 6 can be adjusted by knob 43 to obtain a desired temperature setting for a given humidity. A modification, Fig. 2 (not shown), has a potentiometer controller operating in response to thermopile 14 and controlling the position of a cam follower actuating contact arm 45 and a second controller operating in response to thermocouple 16 to control the position of the cam.

Title: Interferential vaccines
IPC: A61K39/295
Filed: 1964-05-20
Abstract: Vaccine compositions, for conferring immunity against virus diseases, comprise a) an inactivated virus as an antigen for causing the onset of immunity, mixed with b) an interference virus which is either a live, virulent or attenuated form of a), or a live related virus, as an agent for reinforcing the immunity initiated by a), the ratio of inactivated virus particles to interference virus particles being at least 1000:1.  By a related virus is meant a virus having a lesser degree of virulence for the species to be protected, and having, with the virus a), an antigenic community which either brings about a crossed serological or tissular immunity, or which shows an aptitude to cause an interference.  Inactivation may be effected by means such as treatment of the virus with ultra-violet rays, with b -propiolactone, or with formaldehyde (later neutralised with sodium bisulphite), or phenol; the vaccines are suitably preserved by freezing, desiccation, or lyophilisation.  They may be administered by inhalation of an atomised vaccine, by ingestion, painting on the mucous membrane, buccal absorption, or preferably by injection. Examples are given for the preparation of vaccines against Influenza, types A and B; Poliomyelitis; Measles; Mumps; Newcastle Fowl disease; and Canine distemper.

Title: Method of and installation for casting metals
IPC: B22D11/115
Filed: 1951-09-05
Abstract: 699,156. Casting-machines; casting processes; moulds. JUNGHANS, S. Sept. 5, 1951 [Sept. 5, 1950], No. 20995/51. Class 83 (i). A rotating electromagnetic field is used to control crystallization by producing flow in the molten metal during solidification of a casting. The mould 101, Fig. 5, may be carried by a table 102 which is moved down by a motor 107 as the casting is solidifying so that the fields produced by two sets of three electromagnets 108 rotate the still molten metal. When applied to continuous casting the mould 2, Fig. 1, may have a water jacket 3 and be reciprocated vertically by a cam 6 and linkwork 7, 8, the magnets 108 producing the rotating fields being stationary. In modifications the means for producing the rotating fields are arranged above or below the mould. The flow in the molten metal may be adjusted to increase the pressure against the mould wall or against the wall of just solidified metal, which is capable of yielding. The flow may also be used to increase the rate of cooling or the density of the casting or to prevent deep penetration of the stream of metal flowing into a bottomless mould. The invention may be applied to the casting of tubes. Castings made by this process are stated to have high deformability as a result of their small non-directed grain. It is stated that zinc cast in a thinwalled water-cooled bottomless mould with a rotating field can be rolled into plates. Specifification 437,064 is referred to.
