Title: Fine adjustment device for permanent magnets with invariable air gap used in electricity meters, measuring instruments and the like
IPC: G01R11/10
Filed: 1923-11-16
Abstract: 207,192. Landis & Gyr,Akt.-Ges. Nov. 17, 1922, [Convention date]. Magnets.-In order to adjust the active magnetic field of permanent magnets with air gaps of constant width in electricity meters, measuring instruments, &c., the flux between the magnet poles is varied by means of a shunt flux the magnitude of which can be regulated by the movement of an iron piece along an axis parallel to the planes of the poles. On the upper limb of the magnet 1 is adjustably mounted a plate 3 of iron or other magnetic material having a slot 4 through which passes a screw 7 passing through a hole in the upper limb and screwing into a brass or other non-magnetic plate 6 on the lower face of the upper limb. Rough adjustment is thus provided for. The plate 6 has a downwardly bent extension 8 through which screws a bolt 9 carrying an iron disc 10 and a disc 11 of brass or other non- magnetic material to prevent the disc 10 from being adjusted too close to the magnet pole. The extension 8 is slotted so as to grip the bolt 9. In a modification, the iron piece 3 is clamped against the upper face of the lower magnet limb, and forms a counter plate by which the magnet is fastened to its support. Specification 133,888, [Class 37, Electricity, Measuring &c.], is referred to.

Abstract: 666,938. Air traffic supervision. SIEMENS BROS. & CO., Ltd., and CLARK, R. I. H. Nov. 17, 1950. [Nov. 18, 1949] No. 29612/49. Drawings to Specification. Class 118 (ii). An electrical system for predicting the positions that a number of aircraft following defined routes will occupy at some future time comprises, for each route, apparatus adapted to be operated at a rate corresponding to a multiple of the ascertained speed of the aircraft on that route which is first caused to take up a position corresponding to the ascertained position of the aircraft and thereafter to operate together with similar apparatus associated with the other aircraft at the said rate until stopped, the indications given for the several aircraft being those predicted for them at a future time corresponding to the moment of stopping. The system may include arrangements so that the apparatus for each route may be operated at a rate corresponding to the speed of the respective aircraft to indicate at any time the actual position of the aircraft and a switch so that the rate of operation may be multiplied by the same factor in each apparatus at a given time so that the future positions of the craft may be predicted. The indicators may be series of lamps each indicative of a location along a route and where there is likely to be more than one craft on a route a like number of sets of lamps may be used or a single set, members of which glow steadily or flash at different rates to represent different aircraft. Sets of lamps of different colours may be used for traffic -in opposite directions. The multiple speed predictor apparatus may be stopped for inspection at any time or may be allowed to run until one of the predicted positions reaches a limiting value when the whole apparatus is automatically stopped. After inspection of the predicted positions the apparatus may be switched back to showing actual positions. The embodiment described with reference to the drawings (not shown) makes use of apparatus comprising two stopping switches of the type used in automatic telephony, one of which is fed with pulses at a rate corresponding to the speed of travel of the corresponding craft and which as it steps round moves the other with it and the second which, while normally following the first, may be fed at any time with pulses at a multiple of the rate of the first to give the prediction feature. Specification 651,807, [Group XXXV], is referred to.

Filed: 1920-10-21
Abstract: 173,121. Dobson, G. M. B., and Brown J. P. Oct. 21, 1920. Logs.-An air log comprises a windmill which controls counter mechanism and is mounted, by means of spiders, in an open-ended casing which has at the periphery flange-like rings having alternating sectional gaps and projections for more or less blanketing or blinding the blade to compensate for interference with the air flow caused by the aircraft. In the construction shown in Figs. 1 and 2, a pneumatic device is operated to actuate counter mechanisms shown in Fig. 6. The means for blanketing the vanes 10 consist of overlapping sectors 16, 17 carried on rings which are relatively rotatable to adjust the size of gaps 18 between the sectors. The motion of the windmill spindle is transmitted through worm reduction-gearing to a shaft 24 carrying a disc 25 which in the position shown in Fig. 1 throttles a Venturi tube 26; the intermitting pressure thus produced in the throat of the Venturi tube is transmitted by a tube 27 to a chamber 28, Fig. 6, with a movable diaphragm 29 which is connected to a lever 33 carrying a pawl 38 acting upon the ratchet 39 of the counting-mechanism. In another arrangement an electromagnet counting- mechanism, Fig. 8, is operated by the make-andbreak device shown in Fig. 4; a slow-motion shaft driven from the windmill carries a contact star-wheel 48 intermittingly engaging a contact blade 49 forming part of the circuit of an electromagnet 56, Fig. 8, the armature of which carries a pawl 38 actuating the ratchet 39 of the counting-mechanism.

A building panel is obtained by packing lightweight aggregate, preferably a " no-fines" aggregate, into a mould, applying retaining means to the uppermost surface and pouring a gypsum slurry into the mould. The mould comprises two U-shaped supports 1 connected by angle sections 4 containing slots 6 serving as bearings for rollers 7 which support a member 8, this member defining the two short edges and one of the long edges of the panel to be formed in the mould. Mould members 14, 15 (which define the faces of the panels formed) are supported by telescopic links 16 and pneumatic cylinders 17. Groove 33 contains an inflatable tube 34 and provides a good seal between the members 8, 14 and 15. In operation, members 14, 15 are moved to their moulding positions, and the space defined by them and member 8 is filled with aggregate. A mould member 40 then engages with the upper surfaces of box sections 19 and plates 38 and is clamped to the members 14, 15 by toggles 44. Air is fed to the tube 34 and vibrators 39, whereupon a gypsum slurry is poured into funnels 52 and passes through retaining means 54 around the aggregate until all the interstices are filled and plaster wells out of holes 56 in a plate 41. Vibrators are then switched off and the plaster allowed to set. When the plaster has set sufficiently air to tube 34 is cut off and toggles 44 connecting member 40 to member 15 are removed.
