Abstract: 1,240,835. Curtain walls; walls. MARLEY BUILDINGS Ltd. 7 Nov., 1968 [8 Nov., 1967], No. 50736/67. Headings E1B and E1W. A building structure, formed from prefabricated panels of e.g. precast concrete, incorporates a glass fibre reinforced plastics bracing element 10 which is clamped, in a horizontal position, between a pair of panels 11, 12. As shown, the element 10 braces an outer wall relative to the main structure 16 and comprises a stiffening portion 13 at right angles to its main portion 14, and a downwardly extending portion 15 which forms a guide for water, the panels 11, 12 being clamped together by bolts. A longitudinally extending projection 19 on the main portion 14 forms a flashing for the wall and serves to locate the panels in position. In another embodiment, the element is provided with a longitudinally extending deformation (101, Fig. 2 not shown) with a projection (102) on its upper surface and a recess (103) on its lower surface. The element may be constructed to act as a beam supported at its ends by e.g. flanking walls.

Abstract: 1,114,487. Electric meters. ZAVOD ELEKTROIZMERITELNYKH PRIBOROV. Nov. 29, 1966, No. 53397/66. Heading G1Q. The movement of a moving iron meter consists of an asymmetrically pivoted iron 8 which moves in slots (7) Fig. 1 (not shown) in each of a pair of facing polepieces 5, 6. The polepieces are different in shape and in distance from the pivot axis 9, so that in general the flux linkage between the polepieces and the iron varies with deflection. The median plane of the slots in the iron and the plane of the iron may be mutually inclined: this too produces a variation of flux linkage with deflection. The polepieces may be attached by screws 3, 4 to the core 1 of the controlling electromagnet 2, such screws allowing adjustment of the polepiece positions. The shapes of the iron and of the polepieces may take various forms Figs.3 to 10 (not shown) designed to produce linear or non linear or short or long scales. The shapes and relative dimensions are preferably such that: (a) the ratio of the distance between the pivot axis 9 and the nearest point on the moving iron 8 on its edge facing the more remote pole face 6 to the distance between the axis and the furthest point on that edge is within the range 0À1 to 1; (b) distances from the pivot axis to points on those edges of the two polepieces which face one another are between 0À1 and 3 times the distance from the pivot axis to the furthest point on the moving iron. (c) at full scale deflection the areas of moving iron overlapped by the nearer and further polepieces respectively are in a ratio between 0À5  and 10. The suspension (not shown) may be a band suspension, and the movement may be damped by air or liquid or inductively.

Abstract: 1,152,257. Selective signalling; counter. GENERAL ELECTRIC & ENGLISH ELECTRIC COMPANIES Ltd. 28 Nov., 1967 [30 Nov., 1966], No. 53593/66. Headings G4D and G4H. The angular position of a disc, carrying magnets 24, 25, Fig. 3, is digitized by an arrangement of four coils A, B, C, D, on ferrite cores, the inductance of each coil depending upon whether a magnet is adjacent to it or not. Adjacent to all the cores is a biasing magnet 23 which, by suitably positioning the working point on the permeability characteristic of the core, results in a larger change in inductance for a given strength of magnet 24 or 25 when it passes a core. Other arrangements of cores and magnets are described in the Specification. The state of each coil (i.e. whether its inductance is high or low) can be detected by arranging that each coil forms part of the resonant circuit of an oscillator. Alternatively, the coils could be coupled together (as in Fig. 4, not shown) and form part of a single oscillator. Each disc, whose position is being digitized could form part of a decade, pawl and ratchet, counter, which may receive pulses from a watt hour meter.

Patent GB-538943-A (GB)
Abstract: 538,943. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Inc. Nov. 20, 1939, No. 30413. Convention date, Dec. 2, 1938. [Class 97 (iii)] [Also in Group XXIX] Control apparatus including gyroscopes comprise a follow-up member having one or more broad ports from which air flows, and a sensitive element connected to a non-contacting cover for each of the ports, each cover having a small aperture therein to provide an air jet which controls the movements of the follow-up member when displaced by relative movement between the sensitive element and the follow-up member. Figs. 1 and 2 show, in perpendicular vertical sections a gyromagnetic compass comprising an air-driven rotor 17 having an east-west spin axis mounted in a frame 20 carried by pivots 21, 22, in a frame 9 rotatable about vertical pivots 12, 13 in a casing 1 containing a window 3 permitting reading of a dial 4 carried by the frame 9. Parallel magnets 31, 32 are pivoted in bearing brackets 33, 34 secured to the frame 20, parallelism being maintained by a non-magnetic connection pivoted to each magnet. Precession of the rotor to follow movements of the magnets relative to the frame 20 is produced by vanes on the magnets controlling air-jets from the frame 20. The driving and control currents are induced by exhaustion of the casing 1 through a pipe 5, air being thus caused to enter the casing through a filter 6 and a passage 7. The passage 7 supplies an annular recess 8 in the frame 9 supplying two side-byside jets 14 driving the rotor by buckets 18 ; it also supplies an annular recess 19 in the frame 20 from which branches 61, 62, Fig. 4, supply jets 69, 70 and broad parts 57, 58, closed by vanes 29, 30 carried by the magnets, holes 59, 60 and being provided in the vanes to produce small jets operative on shutters 63, 64. The shutters are mounted on pivots 65, 66 and are counterbalanced. Displacement of the vanes to the left, as is shown, causes the jet 60 to raise the shutter 64 and obstruct the jet 70, while the jet 59 permits the shutter 63 to free the jet 69. The couple produced by the jets 69, 70 causes the precession. A modification is described in which the jets 59, 60 themselves effect the precession by the reactions due to their positions relative to overhanging projections from the frame 20 ; the reactive torque produced by the jets 59, 60 alone may, alternatively, effect the precession. A construction is described in which a single magnet centrally carried on top of the frame 20 is provided with an apertured vane effecting precession by differentially controlling the air supply to the two driving jets. Specification 394,412 is referred to. The Specification as open to inspection under Sect. 91 comprises also a construction wherein branches 25, 26, Fig. 3 (Cancelled), from the recess 19 supply jets 27, 28 normally half obstructed by vanes 29, 30 carried by magnets. Relative movement between the magnets and frame 20 frees one jet, and totally obstructs the other, to produce a couple precessing the rotor about a vertical axis. This subjectmatter does not appear in the Specification as accepted.
