Filed: 1938-03-03
Abstract: 510,815. Separating solid materials. SMART, F. T. March 3, 1938, No. 6682. [Class 117] Apparatus for separating mixed seeds comprises one or more endless belts which have their surfaces formed with indentations and which pass continuously through the mass of mixed seeds to extract those of a size to be retained in the indentations. In the arrangement shown, two endless bands 6, 7 pass over rollers 8, 9 and 10, 11 respectively. The rollers are driven so that the adjacent runs 6a, 7a of the bands move upwardly through the mass of seeds fed from the hopper 29 into the V-shaped space which is formed by the bands. The angle of inclination relatively to each other of the bands is varied by adjusting the bearings of the rollers 8, 10 in slots 41 which form circular arcs with the axes of the rollers 9, 11, as centres. Clamps 43 hold the rollers in their adjusted positions. The apparatus is mounted in a casing which is pivoted at one end about the driving shaft 33 and is adjustably supported at the other end so that the bands incline downwardly from the feed end to a shoot which delivers the clean seeds. The seeds extracted by the bands are dropped into a hopper 15. One of the bands may be replaced by a plain band, a roller or a fixed member.

Title: A scraper chain conveyor
IPC: B65G19/08
Filed: 1956-03-03
Abstract: 835,108. Scraper conveyers. GROOT, J. G., DE., [trading as HANDELSONDERNEMING OCEANA]. March 3, 1956, No. 6755/56. Class 78 (1). In a scraper conveyer comprising one or more chains 1 running in a trough made up of articulated sections 3 together with terminal sections 4, the scrapers 2 are slidable relatively to the or each chain in a direction transverse to the general direction of movement of the chain in order that the sections may be laid in a sinuous path without causing substantial deviation of the chain or chains from a straight line. Each scraper 2 is of I-section with a slot or slots 5 in its web in which one or more chain connecting pieces can slide. For a single chain a connecting piece consisting of two slide members 8 connected by a pair of ears 11 secured by bolts 12 is used the ends 9, 10 of adjacent chain portions being linked to the ears. By this arrangement the tension in the chain tends to prevent the scrapers taking up a diagonal position. Friction between the scrapers and the trough walls is minimized by the rounded end portions 7 on the scrapers. The terminal section 4 is wider than the sections 3 so that scrapers in both extremes of lateral adjustment relative to the chain are accommodated. In a modification (not shown) a transversely slotted coupling member is provided on the chain in which a portion of the scraper is slidable transversely of the chain.

Abstract: 1,210,603. Magnetic. switches. COMPAGNIE DES COMPTEURS. 13 Feb., 1968 [21 Feb., 1967], No. 7123/68. Heading H1N. A supervisory device for sensing a variable quantity comprises a variable profile cam 1, the rotational position of which is dependent on the value of said quantity, and lever means 18 to sense the profile of the cam to control a set of contacts according to whether the cam is sensed as having been rotated beyond a threshold position, said cam comprising a flexible tape 11 mounted between two relatively rotationally adjustable members 3, 4, one edge 6 of the tape being located in two intercommunicating circular grooves 6, 7 in the member 3, the position of the outer end 14 of the tape, and therefore the threshold position, being adjustable by relative rotational adjustment of the two members 3, 4. When an actuating cam 33 rotates, it moves a roller 20 on one end of a double lever 18 formed of two parts 21, 22 on a common spindle 23 and with interfitting abutment 25 and slot 26 urged into engagement by a spring 27. If the cone is past its threshold position a nose 35 on a member 19 on the lever 18 is stopped at position XI so that the member 19 rotates about its pivot 24 on the lever 18 as the latter moves and the forked ends 36 of the member 19 move a parallel-motion carriage 38 downward so that sealed magnetic contact unit 44 is moved past a fixed permanent magnet 54. Movement of the member 14 is limited by a stop 40 but the lever part 22 may continue to move and stress the spring 27. The attraction of the magnet for the contacts produces forces f1, f2 which tend to retain the carriage 38 in each of its extreme positions. When, on a subsequent rotation of the cam 33, the lever 18 is permitted to move the nose 35 to engage the cam 1 at radius X2, the member 19 engages the stop 40 and rotates to move the carriage 38 back to the position shown.

Title: Drive control system for a hydraulic elevator
IPC: B66B1/04
Filed: 1972-02-16
Abstract: 1378345 Hydraulic control systems for lifts R W BLAIN 16 Feb 1972 [20 Feb 1971] 7134/72 Heading B8L [Also in Division F2] A drive control system for selectively driving an hydraulic elevator at either full or creeping speed, comprises a check valve 2, between a fluid pump 10 and the elevator cylinder 17, a circulating valve 3 between the pump 10 and fluid reservoir 30, and a setting valve 4 operable by a sealing element 14 of the check valve 2 and between the circulating valve 3 and the fluid reservoir 30, the elevator travelling at full speed when the check valve 2 is fully open and all the fluid from the pump 10 passes to the cylinder 17 and travelling at creeping speed when the circulating valve 3 opens to exhaust some of the supplied fluid to reservoir 30. The sealing element 14 of the check valve 2 is spring biased towards the closed position and has tapered peripheral orifices in its cylindrical wall, whereas the valve element 32 of the circulating valve 3 is spring biased to the open position and also has tapering orifices. Fluid supplied from the pump 10 passes into a pump chamber 13, along a passage 36 and 34 to a chamber 18 beneath the movable element 32, and through one line 68 to a first solenoid operated two-position valve 29 and through another line 19 to the setting valve 4 from which the fluid passes along a line 27 to a second solenoid operated two position valve 28. For full speed operation of the elevator, both valves 28, 29 are closed whereby the full pressure fluid from the pump is held in the chamber 18 causing the circulating valve 3 to close against its spring 33 and the full pump pressure opens the check valve element 14 for full flow to the elevator cylinder 17. To obtain the creeping speed, the valve 28 is opened and pressure is released from the chamber 18 through passages 21, 22 and 53 in the setting valve 4, permitting the spring 33 to open the element 32 to exhaust fluid from the chamber 13, whereby the element 14 partially closes restricting the fluid supply to the cylinder 17. Closing movement of the element 14 however raises a contoured stem 42 of the setting valve 4 relative to the passage 53 in the setting valve sleeve 47 to reduce the rate of exhaust of fluid to the valve 28 whereby the pressure in the chamber 18 is stabilized in relation to the movement of the sealing element 14 of the check valve. The sleeve 47 is vertically adjustable (in Fig.) to pre-set the relative positions of the passage 22 and the contoured part 51 of the stem 47, whereby the creeping speed may be pre-set. When the elevator is to be stopped, the solenoid valve 29 is opened to exhaust all the pressure from the chamber 18 and the circulating valve completely opens exhausting all the pumped fluid. The opening limit of the valve 3 is adjustable by a screwed stop 61, 62.

Abstract: 296,073. Tecalemit, Ltd., (Assignees of Soc. Anon. des Etablissements Tecalemit). Aug. 25, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Actuating by liquid or gaseous pressure; diaphragm and liquid piston pumps. - Pumps for use with internal - combustion engines are actuated by the flow of a fluid which is separated from the fluid to be pumped by a diaphragm 7 or a solid or liquid piston. The actuating fluid may be the lubricating oil, the engine cooling water, the engine suction, or the engine exhaust gases. The inlet and exhaust of the oil &c. are controlled by valves 14, 15 operated by the movements of the diaphragm through spring-controlled levers 20, 21. The fluid to be pumped enters the space 6 below the diaphragm through a valve 4 and is delivered through a valve 5. In another form, the valves 14, 15 are of rotary form mounted on the shaft of a turbine driven bv the oil stream. In another form, the oil stream drives a turbine the shaft of which carries a cam or eccentric driving the diaphragm 7. In another form, the oil enters an air chamber where it operates a bevelled piston valve controlling the admission of the oil to the upper face of the diaphragm. In a modification of the last form, the admission of oil to the diaphragm is controlled by a lift valve fixed to the diaphragm and the flow of oil is regulated by an adjustable needle valve. In another form, the oil stream by injector action creates a vacuum in a chamber above the diaphragm, and a valve connected to the diaphragm periodically opens the chamber to atmosphere. A meter may be operated by the valve rod. In another form, the oil inlet valve is closed by the diaphragm on its downstroke, and the pressure of the oil then opens the escape valve. In another form, both inlet and escape valves are controlled by the diaphragm and a pressure-limiting valve is provided on the inlet side. In another form, inlet and outlet for the oil are controlled by a piston valve operated by a bellows diaphragm. In another form, the oil valves are operated by a separate piston exposed on one side to a spring and on the other to inflow oil. In another form, the oil operates the diaphragm by hydraulic ram action.
