Abstract: 328,733. Lloyd, D. March 14, 1929. Lantern screens.-A pivotally-mounted antidazzle or fog-penetrating device for vehicle and like lamps comprises a light-modifying disc or other screen having a central clear portion surrounded by two or more concentrically arranged differently coloured transparent or translucent portions, the colour portion next to the clear portion being darker than the next outer coloured portion. The screen may be formed by placing coloured material between two clear glass discs cemented together at their edges, and the central clear portion may be provided by a hole in the screen. In the form shown in the Figures, the disc comprises a centre circular clear portion 22, an inner annular green portion 23, and an outer annular amber portion 24. The disc is provided with a supporting rim 20 carried by a standard 21 mounted on one end of an arm 13, the other end of which is formed as a boss 14 loosely surrounding a pivot stud 12 which is mounted on the horizontal part 11 of a bracket 10 fixed to the mudguard or other part of a vehicle. The boss 14 is rotatably mounted on the part 11 by means of ball bearings and is provided on its upper side with a cylindrical housing 16 closed by a cover plate 17. 'The housing 16 accommodates a spiral spring 18 whereof one end is connected to the housing and the other end to the stud 12. A Bowden wire 25 is connected at one end to a lug 26 on the housing 16 and at the other end to a finger grip 27 on a dashboard 31 or other part within reach of the driver. The finger grip comprises a shank 28 slidably mounted in a sleeve 30 which is formed at its end 32 as a stop for a transverse pin 29 carried by the shank 28. By releasing the pin 29 from the stop 32 and turning the finger grip 27 through 90‹, the pin 29 enters slots 33 in the sleeve 30 and the disc 19 is returned to its inoperative position above, below, or on either side of the lamp by means of the spiral spring 18. A pin 34 on the part 11 prevents the shank 28 being completely withdrawn from the sleeve 30. When not in use the disc may be protected by a metal shield fitted to or near the lamp, and when the lamp is adjustably mounted on the vehicle the disc may be coupled to the lamp to move with it. The arm 13 may be slotted, or other means may be provided, for varying the position of the disc relatively to the lamp, and when in use the disc is disposed in front of the lamp a distance equal to about half the diameter of the lamp face so as to allow part of the light to be projected laterally. According to the Provisional Specification the disc may be of a single colour.

Title: Process for the manufacture of double salts of niobium chloride and tantalum chloride
IPC: C01G33/00
Filed: 1960-03-10
Abstract: Double salts of niobium or tantalum chloride with an alkali or alkaline earth metal halide are prepared by reacting the vapour of the niobium or tantalum chloride with the solid alkali or alkaline earth metal halide at a temperature above the melting point of the double salt, and withdrawing the liquid double salt as it is formed from the reaction zone. If it is desired to prepare the double salts of niobium or tantalum in lower valency state the above process is carried out in the presence of hydrogen, and at a temperature not below 550 DEG  C.  The preferred alkali-metal halides are the chloride and the fluoride of potassium.  The vapour of the chloride may be passed upwardly through a reaction vessel containing the solid alkali metal or alkaline earth metal halide, the liquid double salt formed being allowed to flow from the reaction vessel into a receiver below the vessel, which is heated to maintain the double salt in the liquid state.

Title: Improvements in Voltage Regulators
IPC: H02P9/30
Filed: 1967-02-23
Abstract: 1,175,431. Automatic voltage control. ROBERT BOSCH G.m.b.H. Feb.23, 1967 [Feb. 25, 1966], No.8672/67. Heading G3R. A voltage regulator for a multi-phase generator 10 having a rectified output on lines 13, 14 and including a field winding connected to successive output phase windings 1, 2 by way of respective thyristors 17, 18, is adapted to supply firing pulses to the control electrodes of the thyristors, the pulses being synchronized with the frequency of the generator and their magnitude and phase relationship relative to the half cycles of applied field voltage being dependent upon the voltage of the phase 3 preceding phases 1 and 2 and upon a direct voltage representative of output voltage variations. Thus the phase voltage of winding 3 is superposed, by way of resistor 53, diode 52 and resistor 35, on the voltage UR appearing across resistor 42, the resultant voltage US being applied to transistor 26 which has its emitter connected to a reference voltage UZ derived from Zener diode 28. The voltage UR is proportional to output voltage variations and is derived from a comparator including a voltage divider 47, 48, 49 connected across the output lines 13 and 14, a reference Zener diode 43 and a transistor 39. The arrangement is such that when the output voltage is below a predetermined value the resultant voltage US is less than the voltage UZ and transistor 26 is conductive; a firing potential is thus applied to the control electrodes of thyristors 17, 18 which conduct to pass full excitation current. As the output voltage builds up, the voltage UR increases and the conduction of transistor 26 is controlled in such a manner Figs. 2 and 3 (not shown) that the thyristors 17, 18 are fired at a point in the half-cycle of applied voltage dependent upon the magnitude of voltage UR. The field current is thus automatically controlled at a value sufficient to maintain the output voltage on lines 13, 14 at the predetermined value.

Title: Data-indicating apparatus
IPC: G05D3/12
Filed: 1951-04-16
Abstract: 693,528. Electric selective signalling system. NATIONAL CASH REGISTER CO. April 16, 1951 [April 22, 1950], No. 8775/51. Class 40 (i) [Also in Groups XVIII and XIX] . An indicator capable of successively displaying a plurality of items is operated by a revolving clutch to move one item position for each revolution of the clutch, a controlling signal causing the clutch to continue operating the indicator until the required indicator item is displayed. The indicator unit comprises, as shown, a drum 25 (Figs. 1, 2) supported between two fixed plates 15, 16, on a shaft 26, one end of which is attached to gears 28, 29. Gear 29 operates an external type wheel 35 through gearing 37, if required. Gear 28 operates through gearing 30, 31, 33, the latter being attached to a shaft 42 driving a cam 43, which co-operates with a roller 44 on a spring urged lever 45. A control lever 48 (Figs. 2, 3) can be engaged by a trip lever 49 in the rest position of the clutch to hold a pawl 46 from engagement with a ratchet 47, which is attached to a gear 50 meshing with a gear 51 driven by a motor (not shown), during the operation of the indicating mechanism. The clutch control magnet 59, when energized, attracts the armature 58 forcing trip lever 49 downwards to release the clutch for operation, the gearing being such that one cycle of cam 43 steps the drum 25 forward by one indicator item. When operated, the armature 58 also presses against a spring blade contact 66 to restore the trip lever 49 when the magnet 59 is deenergized, and to' supply an external indication that the indicator is being set. The shaft 26 carrying the drum 25 passes through a central hole in a commutator 71 fixed to the wall 15, comprising a ring 72 and segments 73, there being one segment for each indicator position. The required indication is obtained by applying to the appropriate segment 73 a more negative potential than to the remainder. A wiper 75 carried by the drum 25 connects the ring 72 to each segment successively, so that a valve 76 (Fig. 6) is normally conducting to energize magnet 59 in its anode circuit until the wiper contacts the negative potential segment, when the magnet 59 is de-energized and trip lever 49 engages control lever 48 to stop the clutch. A further commutator 80 with wiper 81, of similar construction, is also attached to the shaft 26 to provide a read-out means by extending a potential on the ring to a particular segment, for control purposes. The Specification also states that the control signal may be other than a negative potential. Specification 675,946, [Group XIX], is referred to.
