Title: Improvements in scale positioning or reference means for altimeters
IPC: G01L11/00
Filed: 1932-02-10
Abstract: 381,443. Altimeters. KOLLSMAN, P. 47, Dinsmore Place, Brooklyn, New York, U.S.A. Feb. 10, 1932, No. 4016. Convention date, Dec. 10, 1931. [Class 106 (ii).] In an altimeter having indicating pointers and other fiducial reference means co-operating with scale graduations means are provided to facilitate the setting of the instrument for a certain condition with respect to which readings are desired. The setting movement causes a change in the respective readings the change being of opposite sign relatively to a zero or other initial mark on the scale. As shown in Figs. 1 to 3, the indicating and reference setting means are applied to an altimeter 11 rotatably mounted in a casing 12 on a stub shaft 14. The instrument has secured thereto an element 16 formed as a gear wheel and associated therewith is a hub 22 integral with a gear wheel 20. Rotatably mounted on the hub 22 is a pair of gear wheels 24, 26. The wheel 24 carries a wheel 25 connected through pinions 28, 29, 31 with the wheel 26. A pinion 42 associated with the pinion 28, 29 engages the internal teeth of a ring 35 which carries a reference index 36 that co-operates with the scale 32 secured to the hub 22 of the gear 20. The scale 32 is provided with an aperture 33 through which a scale 27 carried by the wheel 26 can be viewed. The denominational indicating elements of the instrument are constituted by pointers 43, 44 on a central spindle 45 and sleeve 46 interconnected by pinions 47 .. 50. The parts are held by a resilient split ring 39 and enclosed by a cover-glass 40 and split ring 41. The reference setting means comprises a pinion 54 on a spring controlled sliding shaft 52 operated by an external knob 53. When the knob is operated in the position shown in Fig. 1, the gears 16, 24 are rotated to set the pointers 43, 44, scale 27 and reference index 36 to the particular condition such as barometric pressure. By first pulling the knob so that pinion 54 engages all three gears 16, 24, 20 the rotation will then cause the dial 32 to turn with the instrument 11 as a unit so that there is no relative movement of the pointers and reference index. In this manner the instrument if on an aeroplane can be set to position the pointer 43 horizontally to aid in the maintenance of level flight. Removal of the screw 56 enables the pinion 54 to be moved to engage the gear 20 alone when it is desired to adjust the reference index initially to compensate for inaccuracies in the instrument proper. Modified arrangements of the dial, pointers and reference means are described in the Specification.

Filed: 1922-02-14
Abstract: 194,112. Smith, W. D. Feb. 14,1922. Petrol &c. filling stations. -Apparatus for delivering weighed quantities of petrol &c. from filli n g stations includes an indicator which at any instant shows the weight of liquid discharged. The apparatus comprises a metal standard 1 containing in the lower portion a motor 13, air compressor 15, air reservoir 19 and pump 17 the last mentioned being connected to an underground reservoir 43. Above these is arranged a pendulum weighing - scale 21 supporting a liquid container 27 which is preferably made of transparent material. Wire mesh 37 above the container permits escape of hydro-carbon vapours. The device is surmounted by an illuminated cap 11. The pump 17 is started and stopped bv the operator by any suitable means and when in operation raises the liquid to the container 27 by way of a pipe 47 terminating in a vertically-slotted end 29 thus delivering the liquid in an horizontal direction and avoiding downward pressure on the container- An overflow pipe near the top of the container limits the extent of filling. When the container is full the indicating pointer 25 of the weighing- scale indicates zero. In order to discharge liquid from the container the operator pulls a rod 85 thus allowing air from the air reservoir 19 to open a discharge valve at the base of the container. The liquid then runs out through a hose and the pointer 25 indicates the weight of liquid withdrawn. When the operator releases the rod 85 the discharge valve closes under the action cf a spring and arrests the flow. To ensure freedom of movement of the liquid container 27 the filling discharge and overflow pipes are connected to the container through mercury seals.

Title: Friction welding apparatus
IPC: B29C65/06
Filed: 1971-02-10
Abstract: 1385471 Welding by pressure ALLWOOD SEARLE & TIMNEY Ltd 8 Feb 1972 [10 Feb 1971 29 April 1971] 4397/71 and 12271/71 Heading B3R Friction welding apparatus includes means for moving one of the workpiece supports in an irrotational manner (e.g. in reciprocatory or orbital motion but without rotation about its own axis), said means comprising a track, a path inclined at less than 45 degrees to the track and a drive member reciprocable along both the track and the path to cause the track to reciprocate transversely of the track and path, the reciprocation of the track causing the workpiece support to reciprocate. In its simplest form the apparatus (Fig. 1) comprises a table 12 supporting a chuck 11 and component 10, the underside of the table forming an inclined track on which as well as on a fixed path 15 a drive member 14 reciprocates. The table reciprocates vertically between guides 13. Two such mechanisms driven from a common rotating crank 31, Fig. 4, may be used to provide orbital motion to a table 24. In order to bring the component to a zero position for the welding stage itself the path may be pivotal, preferably about a central point of the drive member movement so as to be capable of being brought into parallelism with the track so that reciprocation of the drive member may continue without causing displacement of the track and component support. Alternatively the zero position for welding may be attained by use of a variable throw crank mechanism, e.g. of the dual eccentric sleeve type or of the types described in Specification 1,273,250, which is adjusted to zero displacement when welding is to be effected. The component support may be of the type holding several components for simultaneous friction welding. In an embodiment described in some constructional detail (Figs. 11, 12, not shown) means are described for counterbalancing the movements of the component support.
