Title: Improvements in or relating to circuit arrangements in which a signal is supplied to a control device
IPC: H01J21/02
Filed: 1954-12-07
Abstract: 757,687. Television. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 7, 1954 No. 35419/54. Class 40 (3). [Also in Groups XL (a) and XL (c)] A thermionic valve 7 of special construction (see Group XL (a)), basically in the form of a pentode but including an auxiliary electrode 6 disposed between the suppressor 4 and anode 5, is employed in a circuit arrangement for introducing the direct component into a television signal applied to the control grid 2. Positivegoing pulses are applied to the auxiliary electrode during intervals when the television signal assumes a reference level, e.g. during the synchronizing pulses or black level steps, and result in current pulses representative of the level. These current pulses are integrated in a resistance-capacity network 13, 14 to produce a potential varying in accordance with the signal level which is applied back as bias to the control grid. Specification 694,835 is referred to.

[Class 46.] A rotary suction drum filter is divided by radial partitions into compartments 17 each of which has a draining grid 21, with a longitudinally-extending inwardly-projecting nozzle 23 the walls of which are inclined so as to provide pockets with the walls of the compartment such that residual liquid is collected therein, as the compartment passes to its lower positions during rotation of the drum, and is not allowed to return to the cake on the drum. As shown in Fig. 1 each nozzle is divided into two portions by intermediate walls 26<a>. The drum is supported on hollow trunnions 11, 12. The inner end of the compartments is closed by a conical member 19 which has a cylindrical extension 19<a> within the trunnion 12, the space between the extension and the trunnion serving to connect the compartments with a casing 20, which has a connection 20b to a fan or suction blower and an outlet 20<a> for the filtrate. The material under treatment can be supplied to the drum by a trough 33 and chute 34, which are mounted so that they can be tilted together to regulate the supply. A dam 39 is arranged in front of the end of the chute. The main portion of the cake is removed from the drum by scrapers 45 on rods 47, which can be turned to adjust the distance of the scrapers from the drum. The cake falls into a hopper 42 and is discharged. by a conveyer 44. There is a final scraper 52 and a pipe 54 for the supply of wash water. Heated air is supplied at the sides of the drum through housings 56 with heater pipes 57. The draining grids 21 support a filtering- medium which may be of canvas, or wire-mesh.

Title: Seal assembly
IPC: F16J15/32
Filed: 1963-09-12
Abstract: 1,062,648. Seals; piston packing. B. F. GOODRICH CO. Sept. 12, 1963 [Sept. 13, 1962], No. 36001/63. Headings F2B and F2T. A seal assembly between parts, such as a reciprocating rod 11 and its casing 13, comprises a sealing element 19 having a portion 20 which is designed to engage and form primary and secondary seals 21, 26 for preventing the passage of fluid medium between the parts, the surface 40 extending between the seals being responsive to the fluid medium for decreasing the force required to effect the relative movement between the rod and the primary seal 21 with increase in fluid pressure. The sealing element 19, which is of metal, has the portion 20 connected by a thin neck 23 with the main portion of the element and, in the case shown, the sealing edges 21, 26 respectively engage the rod 11 and inner end wall 29 of the casing with substantially straight-line contact when in operation. A loading nut 18 together with an adjusting sleeve 17 which is screw-threaded in the element and slidable on the rod 11 provide for a sealing pressure at least as high as the maximum likely fluid pressure in the system.- In operation, as the pressure in the fluid system: rises, fluid pressure acts on the inclined surface 40 between the seals 21, 26 of the element 19 to provide axial and radial components L, R. The axial component does not deflect the portion 20 because of the action of the abutting end of the sleeve 17 and the seal 26 remains effective. The radial component R, however, tends to circumferentially expand the seal 26 and therefore relieve some of the mechanical load and, while still maintaining its sealing effectiveness, reduces the friction drag on the rod. . In a modification, Fig. 5 (not shown), the secondary sealing edge (45) is formed by a knife edge on the inner end wall of the casing and co-operates with a plane sealing surface on the thick annular region of the sealing element. In this case, the inner wall of the adjusting sleeve (60) is formed with ridges (63) serving to wipe the reciprocating rod of dust &c. The seal assembly may also be used for sealing rotary or static machine parts.

Ignition means for a main gas burner, in which the gas supply to the burner is controlled by a plug cock 10 actuated by a knob 11 on an axially aligned spindle 12 axially movable against spring loading to release a niting peg 13 normally holding the spindle 12 and plug cock 10 in a closed position, comprises a disc 14 fixed on the spindle 12 and a plate 15 mounted on the spindle 12 between the disc 14 and the adjacent end of the cock 10 for limited rotary movement and limited transverse movement, the plate 15 in the closed position of the cock 10 (Fig. 3, not shown) being located in a position in which a portion of its edge projects beyond the edge of the disc 14 and forms a cam adapted to actuate a spring-loaded rod 17 of an igniting device 22 of the burner, the plate 15 being retained in the projecting position, when the cock 10 is opened by frictional contact with the disc 14 and the cock body until the cock 10 is fully open and the spindle 12 is released. As shown, the plate 15 is substantially a quadrant of radius greater than the radius of the disc 14 and a rectangular slot 28 is formed in the plate 15 to receive the spindle 12 the longer sides 29 of the slot 28 being parallel to a first generally radial edge 31 of the plate 15 and in the closed position of the cock 10 the arcuate edge 36 of the plate 15 projects beyond the periphery of the disc 14. In operation, the knob 11 and spindle 12 are pressed in and rotated to thereby rotate the disc 14 and the plate 15 which is carried round by a tag 34 on the disc 14 engaging in a notch 35 in the generally radial edge 31 of the plate 15. As the disc 14 moves round it acts on a spring-loaded cranked arm 16 of the rod 17; the rod 17 then simultaneously opens a valve 21 to the pilot jet 22 and closes a pair of contacts 23 in a circuit between a battery 24 and an ignition filament 25 for a pilot jet 22 to thereby form a flame at the pilot jet 22 to ignite the main burner. When the burner is alight the knob 11 may be released and the spindle 12 moves outwardly to free the plate 15 which drops under gravity into a position, Fig. 5 (not shown), where its second generally radial edge 33 is held by a tag 32 on the disc 14 with its arcuate edge 36 substantially coincident with the peripheral edge of the disc 14. When the cock 10 is moved to the closed position the plate 15 returns by gravity to the position of Fig. 3 (not shown). The ignition may alternatively be performed by a spring-loaded member of a piezo-electric device actuated by the plate.

Title: Improvements in or relating to sheet feeding or discharging mechanisms
Inventor: BEER CLIFFORD NORTHMORE
IPC: B65H15/02
Filed: 1961-10-12
Abstract: 949,880. Feeding sheets. WEYBRIDGE MACHINE TOOL CO. Ltd. Jan. 1, 1963 [Oct. 12, 1961], No. 36695/61. Heading B6B. [Also in Division B8] Apparatus for separating metal or other stiff sheets from a stack one or more at a time, comprises a main platform 1 which is swung with a stack of sheets 3 from a horizontal loading position to a vertical discharge position as shown, a sheet transferring member 10 which is swung to take the sheets from the stack to a horizontal discharge position, and an escapement member 13 for controlling the release of sheets from, and the number of sheets released at a time from, the platform 1 at each operation of the member 10. The platform 1 has rollers 2 to facilitate the loading of sheets from a vertically adjustable table 4, and has an arcuate gear 6 which meshes with a motordriven pinion 7, whereby the platform can be raised about a horizontal pivot to the vertical position. The member 10 comprises arms pivoted on brackets 11 on the platform 1, and is raised and lowered by hydraulic rams 12. The escapement member 13 is pivoted on the end of the platform 1 and is actuated, against the action of a spring 15, by a finger 14 on the member 10 each time the latter is raised to cause the member 13 to release one or more sheets. The separated sheets are lowered by the member 10 on to conveyer belts 21, and are then fed by nip rollers 23 over a roller feed table 22 to a slitting or other machine 25. The raising and lowering of the member 10 is controlled electrically in synchronism with the other parts of the machine. Thus, a light-sensitive means 26 only permits the member 10 to be raised when the conveyer 21 has removed a sheet entirely from that member, and the finger 14 on the member 10, which operates the escapement 13, also operates a microswitch 27 to cause a solenoid valve to allow the hydraulic rams 12 to lower the member 10.

A cascade of variable camber vanes 13, Fig. 2, e.g. for varying the swirl of air at the inlet of a compressor or for forming part of a rotary structure, is arranged between a radially inner shroud and a radially outer shroud 10. Each vane is rigidly fixed at its leading edge portion but the remainder thereof is adjustable by a number of simultaneously-operable actuators 80 circumferentially spaced, e.g. by 60 degrees, around the inner and outer shrouds. The actuators move the remaining portions of the vanes via a rotatable ring 63, pivoted levers 66, 67, and rods 31, 32, Figs. 2 and 4, which pass longitudinally through the vanes. The rods 32 may be adjusted to any position in respective slots 70 passing through outer shroud 10, or to the end positions only of the slots. The vanes may have their camber reversed by the adjustment. In one vane construction, shown in a flexed position in Fig.4, skins 15, 17 are brazed or welded to leading end 14 and to tapering plates 18, 19 forming the trailing end 20. The plates are connected by rivets 21 which permit relative sliding between the plates to absorb relative chordwise movement between the skins 15, 17 during flexure. Members 35, 39 spacedly support the skins while permitting relative chordwise movement therebetween. In an alternative construction, Figs. 7 and 8 (not shown), the skins have a number of depressions therein with the bases of the depressions in opposite skins being held in sliding contact by rivets in a manner similar to that of rivet 21.
