Title: Anti-hunting circuit for an electrical regulator
IPC: H02P9/20
Filed: 1949-01-26
Abstract: 661,963. Automatic voltage control systems. BENDIX AVIATION CORPORATION. Jan. 26, 1949 [April 19, 1948], No. 2198/49. Class 38 (iv). A voltage regulator for an A.C. generator 21, 23 excited by a D.C. generator 1 comprises a carbon rheostat 45 connected in series with the field winding 8 of the exciter generator 1 and controlled by a main electromagnetic winding 75 in response to voltage variations across output lines 30, 31, of the A.C. generator and by an antihunting winding 53. A further control winding 50 acting in opposition to windings 75, 53 effects compensation for load variations on the A.C. generator. The winding 75 is fed from a rectifier bridge 66 supplied from the lines 30, 31 through a calibrating resistance 62. The winding 50 is connected in series with the field 8 and rheostat 45 across the exciter armature while the antihunting winding 53 is connected across the field 8 and winding 50 in series with lamps 58 the resistance of which increases with current flow to provide a delayed compensation on current changes in the winding 53 and thereby effect an antihunting action in the operation of the rheostat 45. A secondary antihunting effect to provide for conditions of high generator speed and lowfield current is derived by feeding a differential component of the current in the main winding 75 to the antihunt winding 53 via a condenser 85. Specification 619,955, and U.S.A. Specification 2,427,805, are referred to.

Title: A tape position selector apparatus
IPC: G08G5/00
Filed: 1969-01-15
Abstract: 1,245,496. Display unit for control panels. CROUZET. 15 Jan., 1969 [18 Jan., 1968], No. 2286/69. Heading G5C. [Also in Division F2] A device for storing and displaying information relating to an aircraft flight path comprises: a casing 3 (intended for fixing in a control panel); a drawer 2 sliding in casing 3 and which may be unlatched from the casing by means of a push button 1; a photo-electric reader having a receiving unit 9; a unit 4 for loading in drawer 2 and containing a coded recoiling tape 5, and studded wheels 10 for indexing it; and manual control means, e.g. a knurled disc 6a, for producing movement of the tape 5. The tape 5 has translucent code marks (5b), Fig. 8 (not shown), for reading by the unit 9, stop marks (5c) for producing extinguishment of a lamp 7 when correct viewing alignment has been obtained, and visual display areas (5a). Exact alignment is ensured by a spring-loaded detent ball 11. The tape is rear-illuminated by an encapsulated lamp array 8. Sprockets 10 are driven by friction wheels 18a (Fig. 4). Tape tensioning arrangement. (See also Division F2).-The user rotates knob 6a clockwise; this rotates a pinion 12, and hence a pinion 15, which meshes with a pulley 13-14. Pulley 13- 14 drives a pulley 17 via a belt 20; since pulley 17 is of larger diameter it rotates more slowly, thus tensioning the display tape. But if the user rotates knob 6a counterclockwise, a ratchet tooth coupling (15a, 14a), Figs. 5, 6 (not shown) between wheels 15, 14 tends to disengage these wheels, causing cheek 14 of the pulley to move axially towards cheek 13. Resultingly pulley 13-14 increases in diameter, whereby it rotates slower than pulley 17, thus again increasing tape tension. A roller 21 keeps the underside of the belt 20 under tension.

Title: Improvements in or relating to internal combustion engines
IPC: F02C7/04
Filed: 1953-02-28
Abstract: 738,511. Gas-turbine plant; jet-propulsion plant. JAPOLSKY, N. S. May 28, 1954 [Feb. 28, 1953], No. 2570/53. Class 110 (3). [Also in Group XXXV] A jet or like internal-combustion engine comprises an annular passage which has a part 10 of increasing diameter but reducing area in which incoming air is compressed by rotation produced by the field of conductors 14, 15, a part 11 in which fuel from ducts 13 is burnt to increase the axial air-velocity, and so generate current in conductors 14A, 15A and diverging part 12 in which the air expands to produce a jet thrust, or to drive a turbine, or to generate current in conductors 114A, 115A. Conductors 14 are connected to a polyphase H.T. transformer and produce an electric field which ionises the incoming air. The conductors 15 are supplied with current which produces a rotating field in the magnetic laminµ 16 embracing them. These two fields thus co-operate to produce a rotating force on the air in duct 10. The conductors 14A, 15A are arranged to produce or react to a travelling field. Conductors 14A are charged with polyphase H.T. from the same source as conductor 14, so as to produce a travelling electric field which ionises the combustion products. Windings 15A carry magnetic laminµ 16A so that they produce a travelling magnetic field which is arranged to be of lower speed than the combustion gases in duct 11. The effect of this is to generate electric power which, provided a small magnetizing current is supplied, may be used to energize conductors 14, 15 through a phase-shifter. In the same way, conductors 114A, 115A may be used to supply additional power for an outside load. If desired, the inner member 2 may also carry windings.

Filed: 1920-01-27
Abstract: 143,839. Soc. Anon. des Etablissements Continsouza. May 17, 1919, [Convention date]. Kinematograph apparatus.-In a kinematograph. projector, film-centring is effected by rotation of the intermittent sprocket, the mechanism being such that the phase of the film movement is not affected by the rotation; consequent adjustment of the shutter is unnecessary. As shown in Fig. 5, a pinion 11 drives the intermittent sprocket 23 through skew pinions 13, 14, the shaft 15 of the pinion 14 carrying a pin-wheel engaging a Maltese cross 22 on the shaft of the sprocket 23. The shaft 12 of the pinion 11 and the shaft of the sprocket 23 are co-axial, and the shaft 15 is mounted in a cylindrical box 16 rotatable around the shaft 12 by a lever 24. Rotation of the box rotates the sprocket 23 and centres the film. To prevent alterntion of the phase of the film movement, the pinion 13 is slidable on the shaft 12, and its position is controlled by a guide 17 having a spindle 18 projecting into helical slots 19 in the cylindrical box 16 and horizontal slots 20 in the frame 21. The movement of the pinion is such that the position of the pin on the pin-wheel in relation to the slot in the Maltese cross is unaltered by adjustment for centring. The Specification as open to inspection under Sect. 91 (3) (a) describes also a form of centring- device in which a differential mechanism is provided in the shutter shaft. This subject-matter does not appear in the Specification as accepted.

Title: An improved process for the manufacture of guanidine and salts thereof
Filed: 1949-01-31
Abstract: Guanidine is freed from combination with a strong mineral acid by treatment with an alcoholic solution of a metallic alcoholate, the alcohol from which the alcoholate is derived and the alcohol used as solvent each having more than two carbon atoms per molecule.  Salts may be obtained on addition of an acid.  In practice both alcohols are the same.  The guanidine may be isolated by concentrating to 40-50 per cent and adding a liquid miscible with the alcohol but a non-solvent for guanidine, e.g. petrol.  If necessary the guanidine salt may be isolated by a similar process.  Salts specified include members from the following classes: fatty acids, e.g. formate and oleate, aromatic acids, e.g. benzoate and phthalate; alkyl- or aryl sulphonates; polyacids, e.g. maleate and oxalate and weak mineral acids, e.g. sulphites and sulphides.  In examples: (1) guanidine nitrate is refluxed with anhydrous sodium n-butylate in n-butanol, sodium nitrate removed and the free base isolated after concentration as above; (2) guanidine, in butanol, prepared as in (1) is treated with carbon dioxide and a little water and the carbonate isolated on addition of a petroleum fraction and in (3) oxalic acid is added to the alcoholic solution of (1) and guanidine oxalate precipitated.
