Title: Improvements in or relating to driving mechanisms particularly for watches or clocks
IPC: G04B1/22
Filed: 1941-04-17
Abstract: 548,669. Driving mechanisms. JACCARD, P. R. April 17, 1941, No. 5011. Convention date April 1, 1940. [Class 139] [Also in Group XXVI] A driving mechanism, especially for watches or clocks, has an auxiliary spring 20, Fig. 4, or 26, Fig. 5, for transmitting a constant driving torque to the driven element, said auxiliary spring forming a driving connection between on the one hand, a rotatable supporting member 10 subjected to the action of the driving motor 2 and carrying a movementbraking disc 18 connected to an epicyclic gear for imparting rotation to the disc upon rotation of the supporting member 10, and on the other hand a wheel 19 connected to an escapement, and is characterised by the feature that the axle 4 of the supporting member 10 is rotatably mounted in the frame of the mechanism and carries said wheel 19 connected to the escapement, the supporting member 10 and said wheel 19 being rotatable relatively to each other. As shown in Fig. 1, the main spring 2 drives the supporting member 10 through gearing, and wheel 19 is connected by gearing to the escapement of a watch 8. A pinion 11 on member 10 rotates round a stationary gear 12 fixed to the frame, and through a gear train, not shown, rotates braking disc 18 rapidly as member 10 is rotated by the main spring. Post 10c on member 10 acts on auxiliary spring 20 carried by wheel 19 to urge the wheel in the direction shown in Fig. 4. Wheel 19 is controlled by the watch escapement through pinion 5 and so rotates intermittently, the part 21 in turn braking and releasing braking disc 18 as spring 20 bring them into contact and allows them to separate. In a modification, shown in Fig. 5, member 10 has a projection 22 to which are pivoted levers 23, 24, while a tension spring 26 joins pin 27 on wheel 19 and arm 28 pivoted on member 10. With member 10 stationary, and member 19 rotating under the influence of spring 26, pin 25 operates lever 24 to lift lever 23 from braking disc 18, which then rotates to allow member 10 to rotate again, thus allowing lever 23 to return to press again on disc 18. Teeth 30 on member 28 mesh with gear 31 rigid a button 32 on axle 4. Button 32 can be rotated to vary the tension of spring 26. In a further modification, (Fig. 6, not shown), the arm 28 is replaced by a lever rocked periodically by a cam in the gear-train between pinion 11 and disc 18. In yet another modification, (Fig. 7, not shown), the braking effect is produced by having gears mounted in both members 10, 19 so that relative movement tilts the axles causing the gears to rub against member 10. Instead of being connected to an escapement, the wheel 19 may be connected to a movement regulating device effecting a continuous movement, such as a centrifugal governor or a flywheel. Alternatively, the wheel 19 may itself constitute a flywheel. In such a case, there will be a continuous slipping between the two contacting surfaces.

Title: Improvements in or relating to Reservoirs for Braking Systems
IPC: B60T17/22
Filed: 1968-01-31
Abstract: 1,164,070. Reservoirs for braking systems. ALFRED TEVES G.m.b.H. 31 Jan., 1968 [2 May, 1967], No. 5012/68. Headings F2E and F2F. A dual-chamber reservoir for a dual-circuit braking system has a fluid-level warning arrangement in each chamber and a device mounted above the partition between the chambers which prevents the passage of fluid from one chamber to another. In the Figure a partition 4 separates two chambers A, B, each containing a float 10 operating electric contacts to indicate low fluid level. Above the partition is a cap 13 and screen 14 so that air can pass freely from one chamber to the other between the screen 14 and the neck 11. Under these is an element 12 carrying two hollow arms 15, 16 to allow passage of fluid between the chambers to equalize the levels. If the vehicle stands on an inclined surface or if it is rapidly braked or accelerated, the fluid cannot pass from one chamber to another to give a false indication of low level in one chamber.

Title: Apparatus for coiling or reeling hot metal rod
IPC: B21C47/26
Filed: 1955-02-21
Abstract: 764,670. Winding and reeling. MORGAN CONSTRUCTION CO. Feb. 21, 1955 [March 5, 1954; April 14, 1954; June 11, 1954], No. 5076/55. Class 83 (4). Apparatus for coiling hot metal rod includes a reel and a cover for the reel and is characterized by the provision of an air cooling conduit extending into the cover and of means for removing said cover and conduit from the reel to permit the removal of the coiled product therefrom. Steel rod from a hot rolling mill is led into a reel housing 13 through an opening 52 therein to coil, on a loose plate 38, between inner and outer rows of pins 40, 41 upstanding from a rotated plate 42. Cooling air is blown by a fan 20, down a duct 21, which telescopes into a duct 28 secured to a lid 24 resting on the housing 13, through the duct 28 and an aperture 27 in the lid 24 on to the coiling rod. The air passes out through slits 50, 51 in the wall of the housing 13 the slits being inclined oppositely to the direction of rotation of the pins. The slits of upper row 51 may be smaller than those of the lower row 50. When the rod has been coiled a shaft 49 lifts the plate 38 up over the pins 40, 41 to the level of the top of the housing 13 at the same time as hydraulic cylinders 32 lift the lid 24 and duct 28. A pusher then pushes the coil off the plate 38 on to a conveyer. In another embodiment, Figs. 4, 5, 6, a lower part 118 of the telescopic cooling air supply duct extends through, and is carried by, a domed cover 135 resting on a reel housing 117. Air passes down the duct, over a conical diffuser 134 secured to its lower end, up around the coils and out through pockets 138, 139 of the housing to a conduit 140. The lid 135 is raised by chains 130 running over driven pinions. A pusher 143 running over a roll 142 on the housing 117 pushes the coil off a plate 148 when the latter is raised and the lid is lifted. In a further embodiment, Fig. 7 (not shown), a telescopic cooling air supply conduit extends down through the reel housing lid and air passes out of the housing through apertures in the lid to a telescopic conduit surrounding the supply conduit. Specification 706,545 is referred to.

Abstract: 953,841. Electrostatic separators. PETROLITE CORPORATION. Feb. 12, 1963 [Feb. 26, 1962], No. 5641/63. Heading B2J. Oil-continuous dispersions are resolved during passage between the side walls of channels 10 and electrodes 24 within them, the passage of the dispersion being controlled to obtain uniformity by the provision of apertures 20 in a plate 17 covering the exit ends of the channels. The channel structure is contained within a vessel 12 and has four dead spaces 30 in which insulating hangers 29 are supported to carry an array of cross-members 25 on which the electrodes 24 are mounted. A high voltage source 40 is connected between the vessel 12 and the cross-members 25, an inlet bushing 41 of the high voltage terminal and the insulating portions of hangers 29 being kept in an environment of nitrogen supplied under pressure from the lines 45, 46, 53. The nitrogen-liquid interface is indicated by a level gauge 55 and the level is maintained constant by a float 49 and valve 51. The dispersion to be treated arrives by way of pump 58 and with water or reagent from pump 59 is mixed at 57. The reagent may be an acid or alkali solution the reaction products with which form the dispersed phase of the dispersion. The dispersion is introduced by branch pipes 62 the orifices of which face baffle plates 63. The separated material accumulates in the bottom of vessel 12 and is maintained at a level 71 by a float 70 and valve 67 governing extraction. The dispersion moves upwards into a space between two grids 77 and 90 the auxiliary electric field across which effects a preliminary coalescence. The grid 90 depends from the cross-members 25 and is optional; the grid 77 is mounted on a post 79 and can be moved up and down to vary the grid spacing by means of a winch 82 to 88. Emergence of the treated dispersion through the flow controlling apertures 20 in the plate 17, which otherwise closes the upper part 14 of the vessel 12, produces turbulence and inhibits settlement on the plate 17. What settlement occurs can be bled away through a pipe 95 and to prevent extraction of dispersion freshly arrived in the upper part 14 the apertures 20 may have nipples to raise their delivery point above the settlement plane. The channels 10 need not be of the similar square section shown but may be formed from the spaces between parallel or concentric metal electrodes which are solid-or foraminous. With these alternatives the central electrodes may be plates, screens, or bars. The apparatus may be modified to treat a horizontal flow of dispersion.
