Patent GB-655301-A (GB)
Title: Improvements in and relating to disinfecting apparatus
IPC: A61L2/24
Filed: 1945-06-22
Abstract: Disinfecting apparatus of the kind wherein a vaporized disinfectant is admitted to a preheated exhausted chamber containing the articles to be disinfected, and wherein means are provided by which the preheating, exhausting and disinfecting phases are caused to take place automatically in the proper sequence, is characterized by a condenser and means for conveying the disinfectant vapours to the condenser for recovery of the disinfectant, e.g. phenol, or preferably, formaldehyde.  A diagrammatic representation of the apparatus is provided, comprising a double-walled autoclave, which is first partially evacuated and heated by low pressure steam say up to 45 DEG C prior to the introduction of disinfecting vapours at 62-64 DEG C. Formaldehyde vapour of 3 per cent concentration is generated by heating an 8 per cent aqueous solution, the strength of which may be determined by the rise in temperature resulting from the reaction of a known amount with a known amount of ammonia solution.  The plant includes a switchboard with means indicating the temperature of the formaldehyde vapour and of the double-walled space, and the concentration of the formaldehyde vapour.  For the last purpose, the formaldehyde-steam mixture is completely oxidized, e.g. by copper oxide, and the indication of the carbon dioxide produced is used to operate a relay.  The pressure indicating device is combined with timing mechanism and an alarm, so that the various phases are automatically performed and audibly announced.  Further features shown or indicated are a vacuum pump, a condenser for the discharged vapours, an electrically heated filter for the air readmitted to the chamber, means for atomizing additional formaldehyde solution in the chamber, and a cylinder of ammonia for finally neutralizing residual formaldehyde in the chamber.  The electrical connections are also diagrammatically indicated.

Title: Improvements in devices for, and methods of, separating components from a gas and/orvapour mixture
IPC: F25J5/00
Filed: 1961-05-03
Abstract: 972,193. Cold separation of gas mixtures. PHILIPS GLOEILAMPENFABRIEKEN N.V. May 3, 1961, [May 6, 1960], No. 16031/61. Heading F4P. Readily condensible components e.g. water vapour and carbon dioxide are separated from a gas mixture e.g. air prior to liquefaction or separation, by passing the mixture through one or other of switchable chambers 1, 2 having valved inlets 18, 19, valved outlets 30, 31 and ice-collecting perforated partitions 3, 4 connected by fins 5, 6 to liquid gas reservoirs 7, 8 and the chambers 1, 2 are arranged in series through valved conduits 24, 25 for a short time after a switchover with the regenerated chamber e.g. chamber 2 upstream of the loaded chamber 1 until such time as a layer of ice 17 forms on the screen 4 of the regenerated chamber 2. The feed gas flow is then confined to the relatively ice-free chamber by closing a valve 29 in conduit 24 whilst liquefied gas is run off from reservoir 7 of chamber 1 which is then thawed out. Specification 885,482 is referred to.

Title: An improved method of making rivets and the like
Inventor: TAYLOR ROLAND FOSTER
IPC: B21K1/58
Filed: 1951-07-06
Abstract: 704,404. Making rivets &c. A. T. S. CO., Ltd. May 26, 1952 [July 6, 1951], No. 16068/51. Classes 83 (2) and 83 (4) Extruding.-In a method ot making rivets and like headed articles slugs S of unheated metal are forced into an extrusion die D having a countersinking corresponding to the head of the rivet or other article and a short neck N corresponding to the cross section of the shank said neck joining the countersinking to a cavity of greater cross-section into which the shank is extruded. An extension press for carrying out the invention comprises a frame A having the die D carried by a cross member T. A slidable crosshead comprising a platen G and a base F coupled by columns U slidable in holes in the cross member T is mounted on a piston rod K of a jack L. The base F carries an ejector J. A passage in the platen G is in alignment with the countersunk portion of the die D and a punch P makes a close fit in the passage. In operation a metal slug S is fed to the die through a channel I in the platen G and the punch forces the slug into the die extruding it through the neck N to form the rivet shank and at the same time forming the rivet head. The punch is then withdrawn and the jack L operated to raise the crosshead F-G whereupon the rivet is pushed out of the die by the ejector and blown into a receiver by a compressed air jet. Coated slugs, e.g. slugs cut from aluminium alloy sheet coated on both sides with pure aluminium, may be used to produce rivets having coated shanks and such slugs may be of square or other cross section.

[Class 114] A two-pitch air screw is provided with means for finely adjusting the initial low pitch position of the blades. Bevel gears 3 on the blade roots mesh with a common bevel gear 23 having internal splines 83 engaging corresponding splines on a ring 18 internally splined at 84 to engage corresponding splines on the rotor 19 of a hydraulic vane motor, the stator member 24 of which has peripheral splines 81 engaging internal splines in the hub. One side of the vanes on the rotor 19 is under constant engine oil pressure through passages b, b<1> tending to move the blades to low pitch position, and the other side may be provided with high pressure oil through passages a, a<1> from a booster pump and a valve controlled by the pilot. Stops 32 on the rotor 19 co-operate with stops on the stator to limit the movements of the rotor in both directions. The splines 81, 83, 84 permit angular adjustment of the stator and rotor relatively to the hub and to each other and by suitably selecting the pitch of the splines, the initial adjustments between rotor 19 and the blades may be made in increments of a degree.

Abstract: 953,918. Transistor limiting circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 6, 1960 [May 9, 1959], No. 16126/60. Addition to 847,571. Heading H3T. In a limiter circuit comprising a parallel resonant circuit 1, Fig. 1, a symmetrical transistor 2 with its emitter-collector path connected across all or a part of the tuned circuit, and a parallel-connected resistor 4 and condenser 5 connected between the base of the transistor and a tapping on the resonant circuit midway between the connection thereto of the emitter and collector of the transistor, means are provided for supplying a current in the circuit between the tapping and the base of the transistor in opposition to the conduction direction of the base of the transistor. The means for supplying current comprise a battery 6 and current-limiting resistor 7. The arrangement reduces the damping imposed on the tuned circuit by the transistor at low signal levels. The resistor and condenser combination and biasing arrangement may be replaced by (Fig. 2, not shown) or connected in series with a suitably poled Zener diode. The Zener diode 10, Fig. 3, may be so connected as to apply automatic gain control to a preceding I.F. stage 11 when conductive; the time-constant provided by the condenser 12 may be made short so that the gain control circuit itself provides suppression of amplitude modulation. The Zener diode may be combined with the transistor (Fig. 4, not shown).
