Patent GB-428662-A (GB)
Title: Improvements in and relating to the charging of electric batteries
IPC: H02J7/04
Filed: 1934-09-25
Abstract: 428,662. Charging and discharging batteries. GILL, H. A., 51, Chancery Lane, London.-(Nationale Telephonund Telegraphenwerke Ges. ; 136, Mainzerlandstrasse, Frankfort-on-Main, Germany) Sept. 25, 1934, No. 27555. [Class 38 (iv)] In a battery-charging system the battery B is placed on charge whenever the load circuits supplied thereby on a line lb are switched on, and is disconnected from the supply source N when the battery voltage rises to the fully charged value by a relay RS connected across a resistance EW2 having a high temperature coefficient of resistance which is connected in series with a constant resistance W across the battery. Closure of a load circuit also causes closure of a switch a thereby energizing a relay ANI whose contacts an1, an2 connect A.C. supply to a rectifier G through which the battery B is charged. Charging current operates a relay RL to close contacts rl1, rl2, the former of which energizes a holding magnet and circuit, and the latter closes the energizing circuit of the voltage sensitive relay RS. When the battery voltage rises to its fully charged value the drop across the resistance EW2 rises sharply and operates the relay RS to open the holding circuit of the relay ANI and ANII at contacts rs1 so that, if the switch a is open the supply is disconnected. At the same time contacts rs2 open the circuit of the resistance EW2, and, when relay R4 is de-energized, contacts rl1, rl2, open to de-energize relays ANI and II and RS. A manual switch 4S in parallel with the holding contacts rs1, rl1 is provided so that the battery can be charged at will. Relay RL has high inductance for smoothing purposes, and a resistance EW1 having a high positive temperature coefficient of resistance is connected in the supply to the battery so as to maintain the charging current below a maximum value despite variations in the mains voltage. The resistances EW1, EW2 are of the iron-hydrogen type. If a dry rectifier be used in place of the rectifier G resistance EW1 may be omitted. Theoretical considerations underlying the suitable design of the circuits are discussed in the Specification and the rectifier G is stated to be operated at 20 per cent less than its full load current.

Patent GB-999044-A (GB)
Title: Improvements in or relating to sensing units for a vehicle directing system
IPC: B64F1/00
Filed: 1961-07-31
Abstract: 999, 044. Automatic steering control. E.W. BLISS. July 31,1961 [Aug. 3, 1960], No. 27712/61. Heading G3R. [Also in Division H4] In a leader gear system, e.g. for guiding a taxiing aircraft to a catapulting position, the guide path is determined by substantially parallel conductors 11, 12, Fig. 1, connected in a closed loop energized by a generator 15, the conductor spacing at the end 13 being flared to facilitate entrance of the aircraft to the path. The sensing unit on the vehicle consists of a horizontal coil 20, Fig. 4 and a vertical coil 21, the axes of which intersect. As indicated in Fig. 5 (not shown) when the vehicle is disposed centrally on the guide path the flux linkage and hence the voltage induced in the horizontal coil is a maximum and decreases as the vehicle deviates on either side from the path. The voltage induced in the vertical coil is zero when the vehicle is "on path" and increases in one phase sense or the other according to the sense of deviation of the vehicle. The output signals from the coils 20, 21 are amplified at 30, 31, Fig. 4 and fed to a phase comparator 32 which produces a D.C. output varying in polarity and magnitude according to the sense and amount of the vehicle deviation. This output through a known servo-system 33-37 actuates the steering mechanism to bring the vehicle back on path. At the same time the output of the horizontal coil 20 after amplification and rectification at 38, 39 controls a relay 40 which brakes the vehicle should it deviate so far from its path as to near either conductor 11, 12 or the operative one of conductors 14,14a, b or c, Fig. 1b which may be selectively connected to connect the conductors 11, 12 and so result in the vehicle being braked to rest at different terminal positions along the path. A power failure also causes application of the brakes. Steering may be effected by selective braking of the left and right wheels when an aircraft is in question but as shown, Fig. 4, steering is effected by rotating the vertical axis of the nose wheel 18. In this case Fig. 5 (not shown) the sensing unit is located forward of the nose wheel 18 and rotates with its frame. A second vertical coil may be provided on this frame mounted aft of the nose wheel and connected in opposition to the first coil. The induced voltage in the first coil however predominates and the arrangement tends to eliminate hunting of the steering system as the first vertical coil will cross the guide path before the second when both voltages will assist in zeroising the deviation. Specification 999,045 is referred to.

Title: Improvements in machines for scaling or cleaning flues or tubes
IPC: F28G3/10
Filed: 1920-10-05
Abstract: 154,567. Mikshel, J. J. Nov. 22, 1919, [Convention date]. Cleaning externally.-The cleaning-rollers of machines for scaling the outside surfaces of flues or tubes are arranged to be radially adjustable, in order to deal with flues of varying diameter, whilst at the same time maintaining a practically uniform face-contact. Further, the axes of the cleaning-rollers, which are all rotated in the same direction, are inclined relatively to that of the flue in order to ensure a positive forward feed of the flue by a screw-thread action, the pitch of the " screw " being simultaneously varied, so that, as shown in Fig. 17, a quicker feed is imparted to a small flue (full lines) than to one of a larger diameter (shown dotted). This ensures a uniform cleaning action over each unit length of flue, irrespective of its diameter. The flue T, Fig. 3 is fed through a central guide tube 38, Fig. 5. Each of the three cleaning-rollers 20 is carried by a shaft 23 driven through a universal shaft 26 from gearing 75, 76 at the rear of the machine. The bearings 33 for the shafts 23 are carried by brackets 32 integral with spring- pressed plungers 55, which may slide and rotate within cylinders 56 formed at the ends of three radially-adjustable guide-members 29, Fig. 5, sliding in guides 44 on a face-plate 22, Fig. 7. These guide-members are secured by a stud 46, Fig. 7, passing through a radial slot 48 in the outer face-plate 22, to a block 47 adapted to slide in cam-slots 49, Fig. 3, formed in a ring 45, which is mounted on an annular rib 51 at the rear of the plate 22 so as to rotate thereon. As the ring 45 is rotated relatively to the face-plate 22, bv means of a screw shaft 81, it is obvious that the bearings 33 and the cleaning-rollers 20 will be drawn radially outwards to accommodate a flue of larger diameter. The slots 21, Fig. 7, which guide the bearings 33 in their outward movement are not truly radial, the divergencebeing sufficient to rotate the cleaning-rollers slightly about the plungers 55 as axes, in order to obtain the variable screw-feed action previously referred to. By adjusting spanner nuts 89 on the terminal sleeve unit 86 of the screw shaft 81, and providing a weight to operate the ring 45, the machine can be set so as automatically to clean shouldered flues, i.e. flues having two different diameters. The teeth of the cleaning- rollers are graduated in depth and in sharpness. and those of each roller are offset relatively to the others, in order to obtain the most effective cleaning action.

The lower clamp g forms the end of an arm g<1> which has, at its inner end, laterally projecting pins g<3> to engage outwardly dished grooves e<1> of a floating member e. The member e, positioned between the bars a<1>, a<2>, is grooved on its upper surface to receive the cable c. The side bars a<1>, a2 are pivotally mounted on trunnions d<1>, d<2> formed on suspension straps d. Lugs d<4> on the tower ends of the straps d are.adapted to strike and raise the member e when sufficient angular movement takes place between the bars a<1>, a2 and the straps d, e.g. if the cable breaks. Lugs d<8> on the bars d engage in vertical slots e<4> in the member e. On breakage of the cable, the member e, released from pressure, tends to rise and withdraw the clamps g, h through the action of the studs g<3> in the grooves e<1>. Should the clamps g, h bind through the unbalanced pull of the broken cable, the whole clamp will be drawn to one side and lugs d<5> on the straps d will come into engagement with the bars a<1>, a2, the lugs d<4> at the same time striking up the member e.
