Title: Escapement-controlled drive apparatus
Inventor: NORDIN ROBERT WALDEMAR
IPC: F16H33/02
Filed: 1966-06-16
Abstract: 1,144,069. Escapements. TELETYPE CORP. 16 June, 1966 [6 July, 1965], No. 26950/66. Heading F2X. Intermittent drive apparatus comprises an escapement wheel 20, a rotatable arrangement constrained to rotate in only one direction under control of a constant drive torque, a pawl 30 for limiting movement of the wheel 20, and a resilient coupling between the rotatable arrangement and the wheel to urge the latter in the same direction as the rotatable arrangement when released by the pawl 30. The rotatable arrangement consists of a flywheel 22 connected by a spiral spring 34 to a cup-shaped extension 40 of a toothed pulley 41 driven by a toothed belt 43 and a torque-limiting coupling 46 from a motor 45. A torsion rod 14 forms the resilient coupling between the flywheel and the member 20 and a one-way brake 23 prevents reversal of the flywheel when the torsion rod is fully wound. The spring rate of the torsion rod and the mass of the driven member are chosen to decelerate the escapement wheel before engagement with the pawl and to permit flywheel 22 to unwind reverse torque in the rod 14 before it can cause the escapement wheel to rebound. The escapement drives the paper-feeding sprockets 10, 11 of a telegraph printer.

Patent GB-209492-A (GB)
Title: Improvements in or relating to electric motor control systems
IPC: B60L15/04
Filed: 1922-10-11
Abstract: 209,492. Hewitt, L. B., and Metropolitan Electric Tramways, Ltd. Oct. 11,1922. Safety arrangements and connections.- In a motor control system where field weakening means such as a shunt or diverter are subject to overload conditions, the establishment of the diverter circuit is dependent upon an automatic relay having a tapped or divided winding. Connections of the motor armature and field to the divided magnet are such that the relay responds to a smaller value of working current when it is called upon to prevent the. field from being weakened and to a greater value when it is called upon to restore the field by breaking the diverter circuit after the latter has been previously established. Two or more divisions in the relay magnet winding may be made in order to deal with field weakening in two or more steps. Several such relays may be adapted to act successively. Fig. 5 shows the essential connections as applied to a vehicle by two series motors 10, 12. Field weakening shunt resistances 27, 127 are put in, when required, by switches 29, 30 controlled by manual means not shown and subject to the energization of a magnet coil 39 connected to line through the contact 40 of an overload relay with a tapped winding 33. Owing to the diversion of part of the motor-armature current from the relay tapping when the switches 29, 30 are closed, a greater degree of overload is subsequently necessary in order to break the contact 40, and thereby re-open the switches 29, 30. In a modification for use with shunt motors, two separate windings replace the tapped winding or the overload relay. Further modifications adapt the invention to field weakening means operating in two or more steps.

Title: Improvements in or relating to scanning cathode ray tube arrangements
Inventor: BENNETT CHRISTOPHER JOHN
IPC: H04N3/30
Filed: 1963-07-12
Abstract: 1,092,091. Cathode-ray tubes. MARCONI CO. Ltd. May 6, 1964 [July 12, 1963], No. 27618/63. Heading H1D. In a scanning cathode-ray tube, the elemental areas of the surface to be scanned receive elemental cathode rays from a plane array of sources arranged with respect to a corresponding array of deflectors, each consisting of horizontal and vertical deflection plates, such that an elemental ray passes through to the surface only when the voltages across the horizontal and the vertical plates of its associated deflector have predetermined values but is otherwise deflected on to one or other of the plates, means being provided for applying varying voltages to the horizontal and vertical plates of all the deflectors such that the predetermined voltage values occur in each set in turn in accordance with a predetermined sequence. Each set of deflector plates 1, 2, 3, 4 is disposed opposite a corresponding cathode C, and permits the passage of a ray from the latter to a fluorescent screen when the voltage difference both between plates 1 and 3 and between plates 2 and 4 is zero. In each row, the pairs of plates 2, 4 have corresponding electrodes connected together, the pairs of plates 1, 3 being tapped along a series resistance circuit, while in each column this manner of connection applies to plates 1, 3 and 2, 4, respectively, sawtooth signals being fed from sources 51 and 52 to the two series resistance circuits whereby the area of the fluorescent screen is scanned. Modified arrangements are described in which the number of separate deflector plates is reduced by making adjacent deflectors share a common plate, deflection in the adjacent deflectors being then in opposite directions (Fig. 3, not shown), and alternative modes of connection are described requiring fewer separate resistors (Figs. 4 and 5, not shown). The scanned surface may be either continuous or an array of elemental areas corresponding to the cathode array; may be of storage type, e.g. for a storage tube or television camera; or may consist of a plurality of secondary emitting surfaces. Other modifications referred to include the use of photo-electric, tunnel emission, or secondary emission cathodes, and a cathode arrangement constituted by a primary sheet photo-cathode, the emission from which is shared by a plurality of discrete secondary emission multipliers, each acting as one of the sources. Electron multiplication may also be provided between the deflectors and the scanned surface.

Filed: 1930-09-16
Abstract: 363,367. Directing vehicle lamps. TRITTON, J. S., 4, Park Road, Surbiton Hill, Surrey. Sept. 16, 1930, Nos. 27678 and 27811. [Class 75 (iii).] The lamps at either side of a vehicle are turned one at a time from the steering mechanism by a single pivoted operating lever at the front of the vehicle having its ends co-operating with lateral fingers on the lamp spindles either directly or through a link and a transversely movable member. The lamps 1 are mounted in bearings 3 on the cross-bar or dipping shaft 18, springs 8 maintaining them normally in the straight ahead position. A lateral finger 11 is fixed to each lamp spindle 2 and engages a pin 15 or 16 at the ends of a pivotal bar 14 mounted in a bearing 13 on the dipping shaft and connected by a rod 17 with the steering gear in the manner described in Specification 278,464, [Class 75 (iii), Lamps &c., Details &c.]. Turning of the vehicle to the right causes anticlockwise movement of the 'bar 14 thus turning the right-hand lamp but leaving the left-hand lamp in its straight ahead position. Dipping of the lamps is effected by turning the shaft 18 in its bearings 19, 20 by a lever 23, toggle links 24, 25 and a rod 27 connected by Bowden cable to control mechanism operable by the driver, stops 28, 29 on the toggle levers limiting the dipping movement. In order that the dipping motion may not affect the swivelling motion the rod 17 is arranged to act through the axis of the dipping shaft 18, a U-shaped member 21 being formed in the shaft between the jaws of which the rod 17 is connected by a universal joint to a pin 22 on the bar 14. When dipping is not required the lamp bearings 3 are mounted in a fixed cross-bar. A reversing link 30 may be connected in the transmission from the steering gear or the pins 11 may engage the outer faces of the fingers 11 which point away from each other the bar 14 being then provided with curved ends passing around the lamp supports. In a further modification, Fig. 10, the bar 14 is replaced by a bell-crank lever 34 pivoted on the dipping shaft 18 at 37 and connected by a link 39 with a rod 41 sliding axially in bearings 42 and provided with pins 43 engaging the fingers 11 which are parallel with the longitudinal axis of the vehicle. The control rod 17 is connected to the other arm of the bell-crank lever by a universal joint in the axis of the dipping shaft 18. The movement imparted to the lamps will be largest for small movements of the steering gear.
