Title: Improved sheet-registering device for overlapped feeding
IPC: B65H9/14
Filed: 1951-02-01
Abstract: 704,615. Feeding sheets. FABER & SCHLEICHER AKT.-GES. Feb. 1, 1951 [Feb. 6, 1950; Dec. 5, 1950], No. 2520/51. Class 100 (1) Sheet-registering devices.-Sheets B which are fed on to a table 13 in overlapping relationship are each engaged from below, near the front edge, by a number of suction nozzles 9 which rise to engage the sheet, move it beneath fingers or hooks 10, and then carry it into engagement with a number of front stops 14, the fingers 10 being pivotally connected to the means which actuates the nozzles. The nozzles 9 are carried on a member 6 slidable on a guide bar 5 secured to a shaft 4a which is oscillated by an arm 4 and cam 3, a further cam 2, arm 7, and link 8 being arranged to slide the member 6 along the bar 5, whereby the nozzles are moved upwardly, to the left, downwardly, and then to the right. The guide fingers 10 are carried by a member 10a pivoted at 10b to the member 6, an extension of the member 10a having a roller 10c cooperating with a cam-track 12 under the action of a spring 11. Prior to the engagement of the sheet by the nozzles 9, the latter are accelerated to equal the speed of the sheet as it moves over the table. The chain dotted position of the fingers 10 is their position when the roller on the extension 10c engages the lower part of the track 12. Spring-urged fingers may press the sheets into contact with the nozzles 9, or, as shown in Fig. 10, a roller 34, on a bell-crang lever 35 operated by a cam 37, may perform this function. In a modified form, the bell-crank lever may be operated to move the roller 34 towards the nozzles 9 and in the direction of movement of the sheets. The front stops 14 are secured to a tube 15 rotatably mounted on a shaft 16 which has eccentric journals mounted in the ends of levers 17 (not shown) which are eccentrically bored and are journalled in the framework. The position of the levers 17 relative to the frame, and that of the shaft 16 relative to the levers can be adjusted whereby the position of the stops 14 can be adjusted up or down or sideways. The tube 15 is oscillated about the shaft 16 by cam means to swing the stops 14 into operative position.

Patent GB-450978-A (GB)
Title: Improvements in or relating to apparatus for concentrating minerals by flotation
IPC: B03D1/26
Filed: 1935-01-26
Abstract: 450,978. Froth-flotation concentration. TUCKER, S., and MINERALS SEPARATION, Ltd., 10, Old Jewry, London. Jan. 26, 1935, No. 2624. [Class 82 (ii)] [See also Group VI] In the concentration of ores by froth flotation the air is delivered to the pulp through a porous medium which extends underneath the pulp and is moved during the flotation so that a part of the porous medium passes out of contact with the pulp while another part comes into contact therewith. Clogging of the medium is thereby prevented and parts of the medium can be cleaned or repaired without interrupting the flotation. In the form shown, the pulp is fed by a pipe 43 into the cylindrical flotation vessel 14 which is mounted on rollers 12, 13 and rotated by a shaft 37. One end of the cylinder has a conical end plate 18 with a flared mouth 19 and the main body of the cylinder and the mouth 19 may be provided with conveying spirals. A plurality of air cells formed as tubes of triangular section 23, Fig. 4, is arranged round the inner surface of the cylinder, the inner walls 25 of the tubes being perforated and covered with a porous medium 27, e.g. perforated rubber sheeting. Each cell is connected by a pipe 29 to a valve plate 22 which rotates with the vessel, each pipe 29 opening into a port 31 in the face of the member 22. An air-distributing plate 32 having an air port 35 connected to an air supply 36 is held against the member 22 by springs 33, connected to a bracket 34 carried by the framework, the dimensions of the port 35 being such that air only passes to those cells which are beneath the surface of the pulp. In a modification, in which the vessel is driven by means of a chain acting on the shaft of one of the rollers 13 or bv direct attachment to the pulp vessel, the air distributing plate is not connected to the framework of the machine but is mounted on ball bearings on the shaft 37, held against rotation by a locking device, and pressed against the valve plate by a spiral spring round the shaft. The tailings are discharged through outlets 40 distributed round the vessel and communicating with pipes 41 which direct the tailings into a launder 42. The outlets 40 may be provided with non-return valves or may be controlled in a manner similar to the air supply pipes. The froth passes out through the mouth 19. In alternative forms the means for admitting the air may comprise a plurality of air distributing tubes each tube being covered by a porous covering, or the porous medium may be in the form of a band passing beneath the pulp.

Title: Improvements in or relating to Apparatus for Dispensing Liquids Incorporating a Reciprocating Pump
Inventor: ROLLINSON JOHN KENNETH
IPC: F01L25/06
Filed: 1967-01-19
Abstract: 1,163,211. Valves. CHADBURNS (RESEARCH & DEVELOPMENT) Ltd. 19 Dec., 1967 [19 Jan., 1967], No. 2877/67. Heading F2V. [Also in Division F1] A valve for the outlet of a pump dispensing a measured quantity of beer (see Division F1) is opened manually, as shown, or automatically by the beer discharge pressure, Fig. 4 (not shown), at the beginning of the pump discharge stroke, and is held open by the flow of beer until the end of the discharge stroke. The valve comprises a valve member 35 guided by a flow regulator member 33, and coupled by a rod 36 to a diaphragm or piston 37a. The effective areas of valve member 35 and diaphragm 37a are substantially equal, a spring 39 biasing the valve member to its closed position. The valve is opened by depressing handle 41, a forked member 42 lifting member 37 and valve member 35. A vent passage 45 through rod 36 is closed by a seal 46 when the valve is open. When beer flows through the valve, the pressure drop across regulator 33 and valve member 35 is such that the valve is held open by the beer pressure on diaphragm 37a. When discharge ceases, spring 39 closes the valve. In Fig. 4 (not shown), handle 41 is omitted, and the effective area of diaphragm 37a is made greater than that of valve member 35, so that the valve opens automatically when the pump discharge stroke begins.

Title: Improvements in or relating to collapsible ladders
IPC: E06C1/56
Filed: 1947-01-29
Abstract: 605,917. Folding ladders. SALAMON, M. Jan. 29, 1947, No. 3080/46. [Class 20(ii)] A folding ladder comprises a number of rungs 2 having sides links 1 pivoted to them, each pair of links other than the end links being longer and further apart than the adjacent links on one side of them and shorter and closer together than the adjacent links on the other side so that the links can nest together as in Fig. 2. The links are straight sided, thus minimising the thickness of the ladder when folded, and when in use the ladder may be spaced from a neighbouring wall surface by two pairs of additional links, one pair 5 being pivoted to the top rung of the ladder and the other pair 7 hinged to the links 5, having slotted ends 7a to engage the next lower rung. For the attachment of the upper end of the ladder a bar 4 on short links 3 is provided to engage hooks inside a room in a building. Fixing chains may also be attached to the bar 4 or the bar made extendable to engage across the inside of a window opening. Alternatively, the top rung may be extendable for this purpose. The rungs are rigid but may have substantial resilience, e.g. be made from metal strip, and may be serrated. The side links are preferably rigid also.

Title: Director apparatus for use on aircraft
IPC: G01P5/00
Filed: 1916-03-01
Abstract: 177,548. Wimperis, H. E. March 1, 1916. Angle - measuring instruments.-Consists in means for determining the ground speed of an aircraft and the wind velocity, and for adjusting bomb-dropping sights in accordance with the data so obtained. A sighting instrument for bomb-dropping up and down wind embodying such means is shown in side elevation in Fig. 1, a part thereof being shown in plan in Fig. 2 on an enlarged scale. A sleeve 20 is carried by a frame 35 which is adjustable along guides 36 fixed to a convenient part of the aircraft and is clamped before use by a clamping device 40, 41, 45, 46. A channel-shaped bar 1 is slidden in the sleeve 20 until a point 26 on the sleeve registers with the air-speed graduation 2<1> on the bar 1 corresponding to the known air-speed of the machine. Within the bar 1 is a right and left handed screwthreaded spindle 4 which is rotatable by a hand-wheel 34 through the gearing shown, and moves two nuts 7<1>, 8<1>, towards or away from each other. Each nut carries a back-sight wire 53, 54. The nut 7<1> has also a pointer 11 which moves over a wind-velocity scade 2 on the bar 1. A bevel-gear 12 on the spindle 4 rotates a second screwed spindle 13 mounted in a frame 14 carried by the bar 1. A pin 16 on a nut 15 working on the screw 13 engages the slotted arm 17 of a bell-crank 19 which is pivoted to the sleeve 20. The other arm of the bell-crank is also slotted and engages the end of one arm 22 of a second bell-crank pivoted at 23 to the sleeve 20. The other arm 25 of the second bell-crank is a " land-now " bar for use as described below. A bar 49 carrying a foresight wire 51 is vertically adjustable in accordance with the altitude relatively to a guide-bar 48 fixed to the sleeve 20. In use, the bar 1 is adjusted in the sleeve 20 for the air-speed of the machine, and the machine is flown at right angles to the wind direction. The band-wheel, 34 is rotated and, through the bevel-gear 12 and bell-crank connections, rocks the land-flow bar until the latter is parallel to the direction of flow of the land beneath the machine. When this position is reached the pointer 11 indicates the wind-velocity on the scale 2. The machine may now be flown up or down wind, and the two backsight wires 53, 54, in the positions to which they have been adjusted, are used alternately according to the direction of flight. With modifications the apparatus may be employed when flying in other directions relatively to the wind. The algebraic sum of the air-speed of the machine and the wind-speed gives the land-speed of the machine when flving up or down wind. Lenses mav be substituted for the sight wires, and the sights may be adapted for use against moving targets. For navigational purposes only, the sighting elements may be omitted.

Abstract: 1,131,341. Gear-cutting. REISHAUER A.G. 27 Jan., 1966 [4 Feb., 1965], No. 3641/66. Headings B3B and B3K. A grinding machine for hobbing gears comprises a template 86 on the work-carriage 3 for causing crowning or tapering of a gear by displacing the work. The work and hob may be driven by separate motors or a single motor. (In previous machines, templates have been provided to tilt the work for crowning or the hob has been mounted in eccentric bearing sleeves to permit a transverse crowning movement.) The work-carriage 3 is traversed by an hydraulic device 5 on a saddle 2 under the control of reversing dogs 95, 96. The work is rotated by a synchronous motor 9 through differential gearing 11, 15 which is locked, when straight-toothed gears are being ground, by a gear 32 and a pinned plate 33. For helical gears, the differential is connected to a rack 49 on the carriage 3 through gearing 39, 46. The hob 68, rotated by a synchronous motor 67, is carried on a slide 63 adjustable on slides 64, 65 on a cradle 58 adjusted angularly by gearing 60 on a slide 52 adjustable by a screw 56. The saddle 2 can pivot about a stub 87, Fig. 4 (not shown), in an eccentric bearing 94. The saddle is moved by the cam 86, Figs. 1 and 3 (not shown), mounted on the carriage 3 and acting through a follower 83, a lever 82, a shaft 76 and an eccentric 77, 79. Springs 80, 88 take up back-lash and the latter relieves the weight of the saddle 2 to assist in moving it. In operation, with a template 86 as shown in Fig. 1, the eccentric 77, 79 is moved to advance the saddle when the ends of the gear are being ground, so producing a crowning effect. The teeth may be crowned at the ends only by two separate templates 98, 99, Fig. 12 (not shown). For tapering a gear, a straight, angularlyadjustable template is used. Concave or other shapes may also be produced on the gears. The work-drive may be released and the work rotated by the hob. The work is then rolled on the hob by operating a motor 93 which rotates the eccentric 94 and so oscillates the saddle about the bearing 77. The hob may be reciprocated vertically instead of the work.
