IPC: G06G1/12
Filed: 1973-07-05
Abstract: 1387555 Calculators H RIEHLE 5 July 1973 [6 July 1972] 32063/73 Heading G4B A calculator comprises three relatively rotatable rings 1, 2, 3, interconnected by planetary gearing and bearing on their co-planar surfaces 1a, 2a, 3a three concentric scales, Fig. 1 (not shown), which are covered by rotatable annular cursors 21, 22. Ring 1 is rotatable about axis 4 by means of a knob 27 attached at 28, 29 to ring 1. Teeth 8 on ring 1 mesh with planet wheels 6 carried by ring 2. The wheels 6 mesh with teeth 7 formed on a base 5. Ring 3 is secured to the base 5. The gearing is such that ring 2 rotates in the same direction as but at only half the speed of ring 1. The scales on surfaces 1a to 3a (Fig. 1), are all logarithmic, the scale on surface 1a extending in the direction opposite to that of the other two scales, and the scale on surface 2a having its graduations spaced by half the distance between corresponding graduations on the other two scales. With such an arrangement, multiplicand, multiplier and product appear along one and the same radial line crossing the three scales. As well as its logarithmic scale, ring 1 may also bear an inner currency-conversion scale. The underside of the base 5 may bear two scales and mount a partly transparent rotatable disc, covering these two scales and bearing a third, and a cursor, overlying the disc, Figs. 3 and 4 (not shown).

Title: Improvements in and relating to luminous signs
IPC: G09F11/23
Filed: 1962-08-21
Abstract: 1,061,381. Advertising signs. J. C. RUDGE. Aug. 21, 1963 [Aug. 21, 1962], No. 32073/62. Heading G5C. An illuminated sign is arranged so that relative movement between the sign and an observer causes the display legend to appear on his retinae only when he is no longer regarding the sign. In Fig. 1 a cylindrical mask with transparent portions 3 rotates round a strip lamp 1, the sign being mounted near a road or railway. Direct observation from a moving vehicle shows merely a vertically bright line of varying length, but the whole legend is spread across the retinae of the observer by the relative motion and becomes visible as an " after image " against a subsequently observed dark background, such as a tunnel wall. In Figs. 3, 4 (not shown) the mask is of disc form. The same effect as the strip light and cylindrical mask can be achieved by a fixed vertical array of lamps, switched in appropriate sequence by contacts engaging a rotating cylinder or moving plate of conducting and non-conducting mosaic form. A complete legend constructed of discharge tubes may be flashed at intervals corresponding to the time taken for an observer to pass across it. Alternatively a plurality of tubes arrayed one behind another each forming one character may be sequentially flashed at the same frequency. Instead of the observer moving, a sign may be carried by a vehicle. A sign may comprise an array of lamps extending along an arm rotating about an axis normal to its length, the lamps being switched by a like mosaic device to display an illuminated legend apparently suspended in space. These devices may incorporate two colours of lamp operated through diodes by positive and negative voltages.

Abstract: 1473121 Control of eddy - current brakes; toothed gearing JAROCINSKA FABRYKA OBRABIAREK PRZEDSIEBIORSTWO PANSTWOWE 23 July 1974 [27 July 1973] 32433/74 Headings F2E and F2Q In a system for eliminating the effect of backlash in driving gears 6, 4, a dynamic electromagnetically - operated brake 3 has a rotor 2 rigidly coupled with gear 4 and means for controlling the current supplied to the windings 9, 10, of the brake so that the braking force is inversely proportional to the gear load. As shown, 9 is a main winding and is supplied from a tapped transformer and rectifier section 11a. An opposed winding 10 is supplied from a section 11b whose input is located in one of the three phase inputs to a motor 12 which drives the gears 6, 4. The output of unit 11b is derived from a variable resistor 13 whose wiper arm 16 is mechanically coupled with the transformer tapping 17. Thus the current in winding 10 is proportional to the current being consumed by motor 12 and to the exciting current in winding 9. The resultant magnetomotive force reaches its zero value when the motor 12 reaches its rated load. To prevent winding 10 from causing unnecessary braking of motor 12 during starting, an auxiliary relay closes the contact 14 of a resistor 15 across the input of section 11b.
