Patent GB-447050-A (GB)
Title: Improvements relating to the process of manufacturing formaldehyde concentrates
IPC: C08G2/08
Filed: 1934-11-05
Abstract: Readily soluble solid formaldehyde is obtained by concentrating solutions of formaldehyde having an acidity not greater than 0,01 per cent calculated as formic acid.  The solutions may be made by distilling off a part of the formaldehyde from a commercial 30--35 per cent formaldehyde to which acid-fixing agents may be added, the distillate having the desired low acid content.  Preferably the acid content is from 0,005 to 0,006 per cent; such a solution when concentrated to 80 per cent solidifies on cooling, but further drying may be effected preferably at low temperatures in a good vacuum for instance to 95 per cent strength.  Specification 421,691 is referred to.

Abstract: 407,139. Electromagnets; reciprocating motors. KENNEDY, H. E., 105, Tunnel Road, Berkeley, California, U.S.A. Nov. 10, 1932, No. 31841. [Class 35.] In an electromagnetic device with an axially movable armature the stator and armature surfaces have an equal numberofco-operating pole-faces formed by a series of low reluctance rings separated by high reluctance rings, the movement of the armature being such that the poles of each pair always remain in operative relation to each other and the pull on the armature being a maximum at the commencement of its movement. In the form shown, the stem 15 of a valve is lifted against the pressure of an adjustable spring 45 when the coil 25 is energized by alternating-current, this energization causing the magnetic laminµ 18 on the armature to align with corresponding laminae 23 on the stator member 21 which is fluidtight. The winding 25 may be similar to that of an induction motor, and may be placed in nearly closed slots in either the stator or the armature. The sections of magnetic material 18, 23 may be placed between preferably thicker layers of non-magnetic material such as aluminium which may have the same or a smaller diameter. Alternatively, the material may be wholly magnetic, alternate high and low flux paths between the stator and armature being furnished by providing axially spaced circumferential grooves in one or both member as shown in Fig. 9. The limit of the armature stroke is adjustable and in some cases, the laminµ may be given a coating of copper or lead.

Abstract: 784,410. Water-tube steam boilers; regulating superheat. BABCOCK & WILCOX, Ltd. Nov. 3,1955 [Nov. 4, 1954] No. 31979/54. Classes 123(2) and 123(3) A water-tube boiler especially for marine use comprises an oil-fired furnace 1 lined with water-tubes and disposed to one side of upright tube banks 2, 5 of water-tubes which, with the lining tubes, extend between a lower water drum 3 and an upper steam and water drum 4. Gases leave the furnace through a tube-screen 31 and flow laterally through an open pass 29 between tube walls 42, 43 into a space 46 adjacent a transverse tube wall 48. The tubes in the lower portion of the wall 48 are offset to provide a gas flow passage into a vertical pass 69 disposed behind the wall and containing superheater tube banks 78, 79. At the top of pass 69 are disposed dampers 84 by means of which the gas flow in the pass and hence the steam temperature are controlled. The gases which do not enter the superheater pass flow from the space 46 first towards and then away from the furnace in successive passages containing respectively the tube bank 2 and 5 and enter a space 67, disposed behind the superheater pass and separated therefrom by a tube wall 49, from which they flow to the stack through a damper-controlled outlet 7. The superheater pass 69 is of such large cross-sectional area, extending behind the tube bank 2 at one side and into an outward extension 71 of the front wall 41 of the unit at the opposite side, that it can accommodate a superheater with a large heat-exchange surface whereby high steam temperatures can be attained with small draught loss. In a modification, the gases from the furnace flow directly into two side-by-side passes the first of which locates a steam generating tube bank at a part disposed adjacent an open part of the second pass of relatively smaller crosssectional area whilst the second pass locates a superheater at a part disposed adjacent an open part of the first pass of relatively smaller cross sectional area which forms a section of the gas outlet flow path from the steam generating bank.

Abstract: 932,734. Aircraft. BRISTOL AIRCRAFT HOLDINGS Ltd. Oct. 8, 1959 [Oct. 8, 1958], No. 32150/58. Class 4. An aircraft having wings with sharply sweptleading-edges has a pair of members providing auxiliary lift surfaces, which members are movable between a retracted position within the wings and an extended position in which the lift surfaces project laterally of the aircraft, and a source of pressure fluid, each member having nozzle means at or adjacent to its trailing edge, which nozzle means, in the extended position of the lift surfaces, faces downwards and from which pressure fluid from the source can be expelled at high speed downwardly in the form of a sheet extending laterally of the aircraft to provide an effect equivalent to additional lift surfaces for the aircraft. The aircraft comprises a pointed body 5, sharply swept low aspect ratio wings 6, 7 and a power plant 34. Supplementary aerofoils 12, 13 are pivotally mounted to extend transversely from or to retract into the leading edges of wings 6, 7 respectively under the action of jacks 33. The trailing edges of aerofoils 12, 13 carry slots which are supplied with pressure gas from power plant 34, the gas emerging as thin sheets which enhance the lift of the aerofoils. Without such device the aerofoils would have to be of greater chord as indicated by dotted lines 10, 11. The flow of gas from the slots (which may comprise a plurality of discrete apertures) may be varied differentially to provide yawing or roll control of the aircraft. Another embodiment is described in which the supplementary aerofoils are of sector shape instead of the rectangular form shown.

Abstract: 1,183,830. Control of stepping motors. TELETYPE CORP. 13 July, 1967 [3 Aug., 1966], No. 32211/67. Heading H2J. A stepping motor 10 is moved in a first direction by the application of a pulse for a predetermined period, followed by a reverse pulse which tends to step the motor in the opposite direction. After the reverse pulse has been applied for a second predetermined period, the original pulse is re-applied so that the motor is stepped without vibration. The motor is controlled by flip-flop circuits 11, 12 of the type in which a positive trigger input is gated with a positive direct-current priming potential before the trigger input is effective. The outputs of the circuits 11, 12, extend to stator magnets, the motor being stepped in a forward direction or reverse direction by the application of a successionof positive pulses on the leads 25 or 26 respectively. In one position of a reversing switch 31, a positive pulse applied to the input of circuit 30 is transmitted through OR-gate 36 to the lead 25. After a predetermined period, a delay circuit 32 produces a positive pulse which is applied to the lead 26 for retarding the rotor. The output of the delay circuit 32 is also applied to a delay circuit 33, which, after a predetermined period transmits a positive pulse through the OR-gate 36 to the lead 25 whereby the rotor continues its movement to a new position.
