Patent GB-561799-A (GB)
Abstract: 561,799. Washing granular material. BLANTYRE ENGINEERING CO., Ltd., and KERR, W. Nov. 20, 1942, No. 16438. [Class 82 (ii)] A washer-box of the U-compartmented or Baum type for coal or other mineral is provided with a supplementary valve or valves for closing and opening a port at the air pressure side of the washer box 10 at a time of high water level in the washing compartment side 10a of the box, so that, when'the water has risen to or nearly to its maximum level in the washing compartment side of the box, the water column on that side will first be depressed and then restored to its high level before it begins its main descent. The supplementary valve or valves operate in conjunction with the main valve element to effect additional control of the air supply and/or the air exhaust. In one form of the apparatus, the main valve element 12 is operated by an eccentric 13 within a valve chest 14 having an inlet port 15 and exhaust ports 16. Adjustably mounted on the piston rod 17 of the main valve 12 is a supplementary valve 18 which, when the water has risen to its topmost level within the washing compartment side 10a of the washer box, momentarily masks the air inlet port 15 whereby there is first produced a more or less abrupt fall of the water level followed by a rise of the water level in the washing compartment side 10a, this abrupt rise being followed by a continuous fall under control of the ports 15, 16 by the valve 12. In another arrangement the object in view may be realised by the employment of a sleeve valve performing combined axially reciprocating and oscillating movements ; or an inlet valve and a separate outlet valve may be provided.

Filed: 1974-12-06
Abstract: 1495700 Grippers BOC INTERNATIONAL Ltd 6 Dec 1974 [6 Dec 1973] 56547/73 Heading B8H A grasping device for use in lifting a pallet 28 comprises a housing 4 to whose side wall 6 three hydraulic cylinders 8 are attached, each cylinder 8 being adapted to actuate a respective plunger 10 for inward and outward movement relative to the interior of the housing 4, the inner end of each plunger 10 being formed as an upwardly projecting lug 18. Before the grasping device is attached to a pallet 28 the plungers 10 are retracted relative to their associated cylinders 8 against the bias of compression springs 12 so that the lugs 18 are hard against the inner surface of the side wall 6. The device is then lowered so that the housing 4 surrounds a member 24 which is attached to the pallet 28. The hydraulic pressure which caused retraction of the plungers 10 is then released so that the springs 12 urge the plungers 10 inwardly towards the centre of the interior of housing 4 so that when the grasping device is raised by a crane (not shown) attached to a lifting eye 2 the lugs 18 engage the inner surface of a rim 20 which projects downwardly from the head 22 of the member 24. Instead of being operated hydraulically the plungers 10 could be operated pneumatically or electromagnetically.

Abstract: 1,206,939. Winding webs. MASSON SCOTT THRISSELL ENG. Ltd., WALMSLEYS (WIGAN) Ltd., H. R. W. MARSH, and C. TAYLOR. 21 Dec., 1967 [23 Dec., 1966], No. 57610/66. Heading B8R. In a two-drum web-winding machine, a motor 17 drives both drums, the first drum 3 via a pulley and belt system 15, 16, and the second drum 4 via a pulley and belt system 20-22 and a differential gear 18. The speed of drum 4 is varied with respect to drum 3 with a brake acting on the third input of the differential ( e.g. on the casing thereof), the brake being controlled in accordance with the size of the web-roll being wound. In the embodiment, a pneumatically operated drum brake (32, Fig. 3) is connected to the casing of the differential gear - via sprocket and chain drive. The loading of the brake is controlled by a cam-operated valve 36. The cam 11 is rotated in accordance with the movement of the web-roll supports 7 on vertical guide faces 5a, 6a, this movement being transmitted to the cam by an endless chain 8 passing round several sprockets 9, 10, and connected to the support 7. As an alternative, the cam 11 may be operated by a follower member riding on top of the web-roll, and in place of the pneumatically operated brake, an hydraulic, electric or mechanical system may be used.

Abstract: A pencil has a lead-gripping collet (16) which tapers externally towards the writing end (3), the collet being held captive between axially spaced fixed abutments (18, 20) whilst a locking sleeve (11), coupled with an operating member (30), and normally urged by a spring (25) away from the writing end (3) into wedging engagement over the collet (16) with the latter located by its rearward abutment (20), is movable manually, by the operating member (30), against the spring (25) to advance the lead until the collet (16) engages the other abutment (18) and thus opens. The collet (16) is lightly entrained by friction in the sleeve even when, open. Because the points at which the collet grips and releases the lead are well defined, the lead is advanced by a predetermined amount at each stroke of the operating member. <IMAGE>

Title: Fluid damping device
IPC: F16F15/023
Filed: 1979-05-04
Abstract: A device for damping both radial and axial motions of one mechanical part relative to another (for instance, the fixed structure of a toroidal race variable-ratio transmission unit and the control sleeve of that unit) comprises a flexible fluid-filled envelope 66 which fills the annular gap between the sleeve 46 and a spider ring 60 which is stabilised relative to the structure both axially and radially. A ridge 71 causes the interior of the envelope to be divided into two volumes, one at each axial end and joined by a constriction in the middle. Relative radial motion between sleeve and ring is damped by distortion of the envelope and consequent rotary movement of the fluid within. Relative axial motion is damped because the relative sizes of the two volumes change, and fluid moves from one volume to the other through the constriction. <IMAGE>
