IPC: E06B9/36
Filed: 1964-06-08
Abstract: 1,085,095. Vertical slat louvre blinds &c. D. PHILLIPS. June 8, 1965 [June 8, 1964; Aug. 26, 1964], No. 23555/64. Heading E1J. In a vertical slat louvre-type blind screen partition, shutter or the like, the slats are so suspended from the runners of an overhead track as to be biased when hanging freely, towards and take up the fully open position. Fig. 3 shows one embodiment in which the slat 7 is suspended from the runner 5 by two cords which twist when the slat 7 is rotated about its vertical axis, and when the rotating force is removed, the cords untwist. In Fig. 4 the spiral pivot fixed to the slat 7 rotates when the slat is rotated, in a bearing 19 and lifts the slat which, under gravity, returns to its original position when the turning force is removed from the slats. This turning force is provided by a bar on one or both sides, and pivoted to a cross arm, in turn pivoted on the track, so that when moved longitudinally it presses on the edges of the slats and causes them to rotate.

Abstract: 520,075. Modulating systems. FORTESCUE, R. L. Aug. 10, 1938, No. 23648. Addition to 504,196. [Class 40 (v)] In an amplifier supplying modulated carrier to a load comprising one valve driven by pure carrier and a further valve supplying and absorbing further carrier frequency power to effect modulation, as described in the parent Specification, a pair of modulation valves having their anode circuits coupled to the load in parallel or push-pull are provided and so arranged that in the absence of modulation the valves absorb substantially no carrier frequency power from the load. The modulation valves may be so connected and driven that in the absence of modulation some carrier frequency current is supplied to the load, and may be driven from a separate source the amplitude of which is adjustable. Alternatively the modulation valves are biassed to points of different curvation on the bottom bends of their characteristics. The Figure shows an arrangement in which the valve VI is driven by pure carrier and the modulation valves V2, V3 are driven in push-pull by the modulating signals from terminals T2 and by the carrier from terminals T3 and additional carrier is supplied to terminals T4 to drive the valves in parallel to avoid loss of carrier frequency power. Specification 506,096 is referred to.

Title: Improvements in brick-kilns
IPC: F27D13/00
Filed: 1924-10-08
Abstract: 242,051. Habla, A. Oct. 8, 1924. Brick kilns.-In a brick kiln a stack of wet bricks is built up alongside a stack of dried ones which are covered for firing, and the waste heat from the stack of burnt bricks utilized for drying the wet bricks. In the kiln shown in Figs. 1 and 2 the burning-chamber 1 is situated between two drying-galleries k, and is fired initially from end fire-places A and subsequently by fuel introduced through the feed holes, the products of combustion passing to the stack c. When the firing is completed dampers h, i are opened, and air which is admitted to the chamber for cooling the burnt bricks is drawn by the stacks l through the drying-galleries. When the burnt bricks are sufficiently cool they are removed, and their place tilled by dried bricks. A single stack c may serve two burning-chambers I, II. In a modififioation, Fig. 4, having a single drying-gallery k alongside a pair of end-to-end burning-chambers b<1>, b<2>, a flue K runs the length of the structure and can be put into communication with the chambers b<1>, b<2> through damper-controlled openings il - - m<1> and i<2> - - m<2>, so that waste gases from one chamber, say b', can be passed through the other b<2> before passing to the chimney c. The dampers are opened in succession, starting with the ones farthest from and nearest to the chimney in the burning and preheating chambers respectively. In another arrangement the chambers b<1>, b<2> are side by side with the flue K between, and the burning-chamber may also be operated as an annular continuous kiln. The wall between the burning chamber and the drying-gallery may be of a temporary nature, and the openings therethrough may be shaped to take conical closing-plugs. The drying-galleries may be covered by sliding metal plates carrying draught-inducing chimneys.
Patent GB-1133595-A (GB)
Title: Improvements in and relating to control systems for steam turbines
Inventor: WATSON WILLIAM GEORGE
IPC: F01D17/14
Filed: 1966-05-27
Abstract: 1,133,595. Steam turbine control. C.A. PARSONS & CO. Ltd. April 3, 1967 [May 27, 1966], No.23930/66. Heading F1T. [Also in Divisions F2 and G3] A pair of emergency stop valves 1, 2 are connected in parallel to control the admission of steam to a turbine and are opened in sequence by admitting pressure fluid through a pilot valve, not shown, to chamber 5 to raise piston 3 against spring 4 to unseat valve 1. Lever 6 transmits the movement of piston 3 to spool 7 and the latter rises to connect inlet 12 with outlet 13, the latter being connected to ports 14 of relay valve 9. Spool 17 of valve 9 is biased to the position shown by a spring or, as shown, by fluid in the control circuit upstream of a trip device communicating with ports 18 and acting on land 17b. Fluid from ports 14 acts on the underside of spool 17 via passages 22, 23 in the spool and causes the latter to rise to connect inlet 15 with chamber 25 via ports 20. Piston 10 then rises to unseat valve 2 by which time the turbine has run up to its governed speed. When spool 17 is fully raised, a shoulder 17c abuts housing shoulder 9a and obturates ports 14. The spool is held raised, however, by fluid admitted to ports 27 acting on the spool via passages 28, 23. Valve 1 can then be tested without influencing valve 2 by venting and repressurizing chamber 5, and valve 2 can be similarly tested by opening and closing a vent valve for chamber 25. During testing of valve 2, stem 24 moves in spool 17 without influencing the latter. Since ports 15, 27 are supplied from downstream of an emergency trip device, the latter cuts off the supply to these ports in response to overspeeding &c., and spool 17 falls under the action of fluid entering ports 18, the rate of fall increasing when the stem 24 moves out of the spool bore to vent the chamber at the base of the spool. As the spool falls, land 17a thereon connects ports 20 to exhaust and valve 2 closes. Stem 24 re-enters the spool bore to again block the latter. The trip device simultaneously functions to close valve 1 and cut off the supply to port 12. The valves 1, 2 are connected to pistons 3, 10 by rods 30, 32 partially visible through openings 31, 33.

Title: Hydraulic power transmitters
IPC: F16H61/56
Filed: 1938-08-13
Abstract: 518,082. Hydraulic power transmitters. LAVAUD, R. S. DE. Aug. 13, 1938, No. 23949. Convention date, Aug. 13, 1937. [Class 69 (ii)] In a hydraulic power transmitter, two sets of fixed radial guide vanes 3, 3<1> are disposed between the blades 5 fixed on a drawing impeller wheel and the blades 11 mounted on a driven turbine and adjustable to vary the speed ratio and to effect reversal. The blades 3, 3<1> are carried by a ring S co-axial with the aligned driving and driven shafts 1, 2. The blades 5 rotate in the annular space 10 and are mounted between a plate 6 keyed on the shaft 1 and a ring 8 secured to the plate 6 by struts 8'. Liquid from an inlet pipe L is supplied under pressure to the space 10 by means of a centrifugal injection pump formed by a spiral-shaped groove 6<1> in that side of the plate 6 which bears against a fixed plate 9. The blades 11 are straight or curved and rotate in the annular space 10'. They are journalled at 12, 12<1> parallel to the shafts 1, 2 in a ring 13 and a plate 14 which is fastened to a plate 15 keyed on the shaft 12, the rings 13 being secured to the plate 14 by struts 13<1>. The blades 11 have projections 18 which engage in slots in a plate 16<1> fastened to a sleeve 16 which is connected by a pin and helical groove coupling to a sleeve 17 slidable along but not rotatable around the shaft 2. Axial movement of the sleeve 17 by an automatically or hand operated handle V therefore rocks the blades 11 about their journals 12, 12<1>. Air and excess liquid pass through an aperture 4<1> into an exhaust circuit which includes a loaded relief valve.

Title: Improvements relating to overload clutches
IPC: E21C31/12
Filed: 1939-08-21
Abstract: 532,350. Overload-release clutches. ANDERSON, A., ANDERSON, BOYES & CO., Ltd. Aug. 21, 1939, No. 24003. [Class 80 (ii)] A driving member 1 has clutch teeth engaging teeth on a driven member 2 splined on a shaft 3, the clutch teeth being so inclined that they tend to disengage under torque. A lever 4 pivoted at 5 carries rollers 6 forced against the member 2 by a spring 9 acting upon an adjustable screw 7 through a cap 12 screwed into a sleeve 10 sliding in a guide 11. The lower end of the sleeve has an inturned flange and is integral with a cam 13 adapted to bear against a roller 8 on a crank-pin 17 carried by a shaft 18 provided with a re-setting lever 20. The roller 8 is normally retained in a position slightly beyond the top dead centre by a stop 21. A second stop 23 is provided on the other side. A plunger 14 slidable within the sleeve has a shank 15 guided in a socket 16 in cap 12. When overload occurs, the element 2 is moved axially, the lever 4 rocked and the sleeve 10 depressed. The cam 13 pushes the roller 8 towards the right thus removing the abutment for the plunger 14 and the lower end of the spring 9 engages the inturned flange on the sleeve and the spring is disabled. The element 2 of the clutch is now disengaged and is supported in this position by light compression springs 24. To effect reengagement, the roller 8 is restored to its normal position by the lever 20.

Title: Improvements in and relating to sealing mechanism for continuous rod cigarette making machines
IPC: A24C5/26
Filed: 1934-08-20
Abstract: 431,664. Cigarette-making machines. AMERICAN MACHINE & FOUNDRY CO., 511, 5th Avenue, New York, U.S.A. Aug. 20, 1934, No. 24015. Convention date, May 22. [Class 130] In sealing mechanism for continuous-rod cigarette-making machines in which an endless sealing belt 24 is heated by contact with an electrically-heated shoe 38 and in which both the sealing belt and heating shoe are supported by a frame 13 movable to carry the sealing belt into and out of contact with the seam of a cigarette rod C, said belt and shoe are so arranged that they are automatically separated when the supporting frame is moved away from the cigarette rod. The frame 13 is mounted on a stationary shaft 12 which is carried by an adjustable vertical slide 7 on the machine bed and which supports a bevel wheel 14 driven by a sprocket 16 connected to the main drive of the machine by a chain 17. The bevel wheel 14 meshes with a bevel wheel 27 on one end of a shaft 26 which rotates in bearings on the frame 13, the other end of the shaft 26 carrying one 25 of two pulleys supporting the sealing belt. The second or idler pulley 23 is located on a shaft 22 which is mounted on an arm 21 pivoted at 20 on a bracket 19, and the latter is pivoted at 18 on the frame 13. The shaft 22 is provided with a cam follower 54, and a stationary cam rail 56 is located on the shaft 12. This arrangement is such that, when the frame 13 is swung about the shaft 12 by a handle 51 to lift the sealing belt away from the cigarette rod, the cam follower 54 will coact with the cam rail 56 and swing the arm 21 about its pivot 20, with the result that the pulley 23 is moved sufficiently toward the pulley 25 to slacken the sealing belt and enable it to move away from the heater shoe. A spring 33 is interposed between the arm 21 of the idler pulley 23 and the frame 13 which is adapted normally to press yieldingly the pulley 23 away from the pulley 25 to take up the slack in the sealing belt due to expansion thereof when heated, and spring-pressed pressure rollers 36 are provided for retaining the sealing belt on said pulleys. The cigarette rod C is propelled through the sealing mechanism, in the direction of the arrow shown in Fig. 1, that is to the left, by an endless rodforming tape 43 driven by a tape wheel 44, the tape wheel 44 and pulleys 23, 25 being driven in the same direction of rotation, namely anti-clockwise, so that the lower run of the sealing belt travels in a direction opposite to that of the cigarette rod.

Title: Method of pelletizing moist particulate material
IPC: C22B1/14
Filed: 1970-05-19
Abstract: 1317593 Pelletizing inorganic material COLD BOUND PELLETS AB 19 May 1970 [27 May 1969] 24077/70 Heading ClA Moist particulate inorganic material is treated by adjusting its composition until the mass is substantially electrically neutral (zeta potential =0) and then pelletizing. The neutral point may be determined by observing the tendency to agglomerate and to optimise visible agglomeration which may be produced by (a) adjusting pH by addition of acid or base, (b) adding solid particulate matter of opposite electrical charge or (c) adding a conventional flocculating agent. The process is applied to the pelletization of particulate mineral concentrates such as those comprising hematite and magnetite.

Abstract: 1,052,583. Compacting packaged material. K. H. SMEDLUND. June 8, 1965 [June 5. 1964], No. 24178/65. Heading B8C. Material is compressed into a sack by a piston 9 (Fig. 2, not shown), whose motion is reversed when the compression reaches a predetermined level; the reversal is effected when a motor 5 driving the piston moves under the influence of the forces it exerts to compress a member 10 and operate a reversing switch 13. In the preferred embodiment the degree of compression can be adjusted by altering the inclination of a camming surface 15 which operates the reversing switch 13 through a follower 14. The motor may drive the piston 9 through a pinion 6 and a rack 7 which may be formed by a chain secured to the piston rod 8. Alternatively the pinion 6 may be replaced by a pulley engaging a wire. Upward movement of the piston 9 is arrested by a limit switch 21 operated through a push-rod 18.
