Abstract: 1,215,851. Heating and cooling granular material; drying particles. BUSS A.G. 8 Jan., 1968 [24 Jan., 1967], No. 1015/68. Headings F4G and F4U. In apparatus for continuous drying, cooling or heating granular or pulverulent material conveyed through a duct in suspension by a gaseous medium, the relative velocity between the gas and the material in suspension is increased by passing said material in suspension through a chamber 1 of diameter larger than that of the duct. A swirl generating member 4 positioned preceding the inlet section 2 and comprising a sheet metal helix imparts a rotary motion to the solids in suspension which, on impingement with the chamber wall, are decelerated by friction. This deceleration is increased by the inclusion of single or multiple braking helices 7 of decreasing pitch affixed to the chamber wall. The solid material is accelerated as it passes through the converging outlet section 3. Each chamber may be equipped with heating or cooling means (not shown). Several chambers can be connected into the duct in tandem. The swirl member 4 may be replaced by a deflector (11) of biconical form (Fig. 2, not shown).

Patent GB-781944-A (GB)
Title: Improvements in and relating to transmission systems of power driven vehicles
IPC: F16H61/02
Filed: 1956-01-17
Abstract: 781,944. Change-speed gearing. SOC. ANON. FRANCAISE DU FERODO. Jan. 17, 1956 [Jan. 17, 1955], No. 1624/56. Class 80 (2). In a motor vehicle wherein an overdrive gear behind the gear box is normally controlled automatically in accordance with speed but can be changed down from overdrive to direct drive at will by kick-down of the accelerator or by a separate control member, the arrangement is such that the engine clutch is temporarily disengaged during such voluntary change-down. In the arrangement shown in Figs. 1, 3, the overdrive epicyclic gear comprises an input planet carrier 12, an output annular gear 14, a one-way clutch 15 between carrier 12 and gear 14 for direct free-wheel drive, and a sun gear 16 which can be locked for overdrive by a transversely-movable member 20 engageable with teeth 19 on the sun gear. The latter can be moved axially to couple it to the carrier 12 by clutch teeth 17,18 during reverse drive. Member 20 is normally held retracted, as shown in Fig. 3, by a spring 26 and is moved to locking position upon closure of a relay switch 29 causing energization from a battery 31 of both main and holding solenoid windings 23, 22, the holding winding 22 being permanently earthed at 53 and the main winding 22 being connected to earth through a switch 55 which is closed when member 20 is in retracted position but is opened by member 20 when it moves to locking position. The accelerator kick-down switch 46 normally connects contacts 41, 42, whereby relay switch 29 is controlled by a speedresponsive switch 49 in series with a switch 48 which is closed only during forward drive; the switch 49 being opened or closed when vehicle speed is below or above a predetermined value. Upon kick-down of the accelerator during overdrive, contacts 41, 42 are disconnected, so deenergizing the locking solenoid, and contacts 43, 44 are connected, completing a circuit including a spring-closed switch 52 and a relay coil 61 which opens a switch 64 to cause disengagement of the engine clutch 66. A switch 69, controlled by the gear lever, causes the clutch also to be disengaged during gear changing in the main gear box. As the member 20 moves to retracted position, it opens switch 52, so deenergizing the coil 61 and causing re-engagement of the clutch. In the arrangement of Fig. 4, a member 80 is movable axially on the sun 16 so as frictionally to connect the latter either to annulus 14, for direct drive, or to the casing 82, for overdrive, the member 80 being normally held by a spring 83 in direct drive position and being moved to overdrive position by hydraulic means 84. The latter is controlled by a valve 85 actuated by a speed-responsive governor 50 with an overriding kick-down control 86 coupled to a switch 87 controlling the engine clutch, a normally-closed switch 88 being opened by the movement of member 80 or by timing mechanism to cause re-engagement of the clutch.

Title: Improvements in or relating to shoe-upper conforming machines
IPC: A43D21/12
Filed: 1934-01-17
Abstract: 431,867. Boot - making machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., Belgrave Road, Leicester.-(United Shoe Machinery Corporation; 140, Federal Street, Boston, U.S.A.) Jan. 17, 1934, No. 1652. [Class 17 (i)] Pulling-over.-Relates to machines of the kind described in Specification 7005/00, [Class 17], provided with means for retarding the upper-pulling movements of the grippers of the kind described in Specifications 1866/12 and 181,474, [both in Class 17 (i)], and consists in the provision of mechanism for reducing the checking action of the retarding means, (1) when the usual manual control for varying the pull is actuated and (2) when the upper has been pulled over and clamped against the last. The machine may be of the kind described in Specification 12304/03, [Class 17], having inwardly swinging side clamps 14 for clamping the upper against the opposite sides of the last near the sole face after the upper has been pulled over, and side wiping elements of the kind described in Specification 7247/01, [Class 17]. The manual control handle 46 which is pivoted at 28 and carries a segment gearing with another on a rock-shaft 40, connected by equalizing mechanism with the side grippers, is connected by a link 92 with an arm pivoted at 86 and moving with an arm 84 engaging a wear plate on a piston 52. This piston is urged upwardly by a spring 80 and reciprocates in a cylinder in a casing 54 filled with liquid. At the top of the piston passages 68 and a non-return valve 70 allow the piston to be raised. At the lower end of the cylinder an opening is adjustably closed by a valve 62 to retard the descent of the piston and consequently the rise of the grippers in their updraw movement. The valve is urged towards its closed position by a spring 114, the valve opening being adjusted by a nut 116 having an operating handle 134, which nut engages a collar on the valve stem. To open the valve when the clamps 14 have been brought to operative position an adjustable cam actuates a link 144 pivoted to a lever 126 having a forked end engaging a spool on the valve stem, which stem is screw-threaded so that the position of the spool may be adjusted. In operation, the updraw is retarded by the resistance to the descent of the piston determined by the setting of the valve 62. At any time, while the upper is being pulled, the operator may further retard the pulling movement by pulling forwardly on the hand lever 46. If, on the other hand, he desires to accelerate it, a rearward push on the handle will depress the piston, causing the valve to open against the spring 114. When the upper pulling is complete, to allow the grippers to be quickly withdrawn to out-of-the-way position, the lever 126 automatically opens the valve.
