Title: Fluid flow control instrumentality
IPC: F15B21/044
Filed: 1969-06-26
Abstract: 1,217,304. Hydraulic motor control circuit. KOEHRING CO. June 26, 1969 [Dec. 13, 1968], No. 32404/69. Heading F1P. [Also in Division F2] In a valve mechanism for controlling doubleacting motor 7, fluid pump 12 passes via check valve 18, passage 15 and line 17 to chamber 16 whence it is admitted to one side or the other of the motor upon raising of spool 19 or 20 by actuation of pilot valve 8 to pressurize port C1 or C2. The other port is simultaneously depressurized to allow the other spool to be lowered by work port pressure applied there above via 34, 35 to exhaust the other side of the motor. When the motor is acting against a load, delivery pressure at 15 is high and acts via 60 on plunger 61 to unseat valve 51 to provide an exhaust path via 30, 53, 52, 13. When the load assists the motor pressure at 15 falls whereas that at 52 rises and the pressure differential across valve 50 eventually unseats the latter to allow the exhaust fluid to flow to 15 thereby supplementing the pump output and preventing void formation in the motor. The exhaust fluid also flows via 67, 68, 57, 69 to assist in keeping pilot operated pump unloader valve 48 closed, and via 43 and pilot valve 8 to assist in keeping the operative spool raised. In Fig. 2, pressure rise at 52 eventually moves valve 80 leftwards and acts in chamber 57 to bias relief valve 72 closed. Valve 80 may be embodied in the relief valve.

Title: Dispensing Device
Inventor: ABPLANALP ROBERT HENRY
IPC: B65D83/14
Filed: 1967-07-14
Abstract: 1,187,263. Spray-producers. R. H. ABPLANALP. 14 July, 1967 [11 Aug., 1966], No. 32422/67. Heading B2F. A dispenser for fluent materials such as powders or viscous liquids comprises a container 10 for a pressurized gaseous or volatile liquid propellant, arranged within a container 20 for the spray material, means being provided to allow gaseous propellant to flow into the material container 20 on operation of a valve actuator head 32. Depression of the head 32 allows propellant to flow through a valve housing 36 by separating a body 37 from a gasket 35 and affording communication through an opening 38 with passages 41, 43 leading to the outlet orifice 40 in the head 32, the propellant thereby flowing across the upper end of a spray material flow passage 39 to entrain the material. A small orifice 44 in the wall of the passage 41 admits propellant into a chamber 45 defined by the top of the propellant container 10 and the walls 46, 47 of the actuator assembly. The walls 46 are made of thin flexible nylon or polyethylene to allow the head to be depressed. The propellant flows from the chamber 45 into the material container 20, through grooves 23 formed in the mouth 21 of the container 20, in order to fluidize a powdered material therein, or to exert pressure on a liquid material and to assist discharge thereof. In an alternative embodiment, for powdered materials, the grooves 23 are replaced by a tube (not shown), having a plurality of outlets below the surface of the material, which leads into the product container 20. The grooves 23 may alternatively be replaced by splines (not shown).

Title: Improvements in or relating to straight bar knitting machines
Inventor: WOODCOCK HERBERT EDWARD
IPC: D04B11/00
Filed: 1961-09-09
Abstract: 1,028,512. Straight bar knitting-machines. WILLIAM COTTON Ltd. Sept. 5, 1962 [Sept. 9, 1961], No. 32432/61. Heading D1C. A fabric is produced on a straight bar knitting- machine which has yarn control elements operating at the selvedges of the fabric to hold the selvedge loops SL and newly laid selvedge yarn NY spaced from each other while the needles operate to press the needle beards and land the selvedge loops on the beards. In one embodiment the elements comprise members 2 each having a projection 2a, each member being displaceable towards and away from the selvedge needle and also displaceable sideways to catch the yarn. The element and its mounting as a whole is also displaceable sideways in synchronism with widening or narrowing displacements to follow the selvedge. The element 2 is slidably mounted in a box 4, (Fig. 3) mounted on rods 5, 6 and is reciprocable towards and away from the selvedge needle by a bell crank lever 8 having one arm 8b projecting between operating bars 9, 10 displaceable up and down by a cam. Sideways displacement of the box 4, to engage element 2 with the yarn at the end of the yarn carrier traverse is effected by a block 12 (Fig. 4) slidably mounted between stops 13, 14 fixed on the rod 5. Cam faced bosses 15,18 on the stops engage similar bosses 16, 17 on a sleeve 19 which is oscillable by an arm 17a engaged by an operating bar 20. Rotation of the sleeve 19 in one direction causes the boss 17 to act on boss 18 to displace the rod 5, and element 2, outwardly of the selvedge, while on rotation in the other direction boss 16 acts on boss 16 to return the rod 5 and the element 2 in the yarn deflecting direction. The block 20 engages a screw 23 which holds the block stationary to allow the rod 5 to be moved, and which is operable to adjust the position of the block during narrowing or widening. In a modification the yarn control element has a square end and is not provided with a lateral motion to engage the yarn.

Abstract: 1,015,001. Electric selective signalling. CAMBRIDGE INSTRUMENT CO., Ltd. Nov. 16, 1964 [Aug. 16, 1963], No. 32451/63. Heading G4H. A portion digitizer comprises a series of electrical contacts sensed by two brushes which follow each other off a given contact as the input position changes, one of the brushes and each of the contacts being in series with a respective device the resistance of which is less at a higher potential applied to the device than at a lower potential, such that a signal current passes through one but not more than one of the contacts in each relative position of the brush assembly and the contacts. The units order of the digitizer shown in Fig. 3 has the above features and comprises contacts K, brush pair J (shown in an alternative position at J<SP>1</SP>) and number indicating tube N. The " devices " mentioned are the neon tube S and the cathode-anode gaps of tube N (though separate neon tubes could replace the latter, Fig. 2, not shown). At any time, at least one brush contacts a contact K, producing the corresponding indication in tube N. If the brushes contact different contacts K, as shown at J<SP>1</SP>, then enough current flows through the brush not having the neon tube S in its lead to reduce the potential across the tube S below the point at which it will conduct. Thus an unambiguous indication is always given. Fig. 3 also shows tens and hundreds orders, the changeover in each when the next lower changes between 0 and 9 being controlled from said lower order by connections via diodes T, V shown. Each order also has its own (single) brush U, W for controlling the indication at other times (during said changeover these latter brushes would be between contacts, e.g. as shown at U<SP>1</SP>). Neon tubes may be replaced by Zener diodes and gearing may be provided between orders.

Abstract: 784,469. Mixing-machines. NAUTA, J. E. Nov. 15, 1955 [Nov. 20, 1954], No. 32643/55. Class 86. In mixing apparatus comprising a conical container 1 within which an oblique shaft 5 carrying screw blades 6 is caused to rotate about its own axis and about the axis 9 of the container 1, the top of the shaft 5 is guided by an annular surface 29 formed on a flange 28 depending from a cover 27. the diameter of the surface 29 being at least one quarter of the diameter of the top edge of the container 1. The end 12 of the shaft 5 is supported in a bearing 10 which is arranged in a plate 11. Two rollers 24, 25 are mounted on the underside of the plate 11 and these run on the annular surface 29. The shaft 5 is driven from a shaft 3, through a cardan joint 4, and carries a toothed wheel 13 at its upper end which meshes with a toothed wheel 14 attached to a pulley 16 mounted on the plate 11. Pulleys 20, 21 are also mounted on the plate 11 and a rope 31 passes round these pulleys 20, 21 and 16 and also round a V-shaped groove 30 formed on the flange 28. The rope drive causes rotation of the shaft 5 about the axis 9 of the container. In a modification, a screw mining member 71, Fig. 5, is driven from a shaft 79 through bevel gearing 78, 77, shaft 76 and chain gearing 80, 89 and 96, Fig. 6. The chain 96 also passes around a sprocket 94 attached to a shaft 93 which carries at its upper end a roller 95 which runs on an annular flange 73 on the cover. The chain gearing is mounted in a box 85. In a further modification, a shaft 60, Fig. 3, provided with screw blades 61 carries at its upper end a rubber bush 63 which is adapted to run on a conical flange 59 attached to the wall of the mixing vessel. Adequate pressure between the bush 63 and flange 59 is ensured by spring-pressed rollers 65, 67 acting on the opposite side of the flange.

Linear - dimension gauges; surface and outline gauges.-Comprises a snap gauge in which the anvils are secured in adjusted position by a screwthreaded adjustable member to the rear of the anvil and a bolt passed through the adjustable member and engaged in the anvil, the head of the bolt bearing against a shoulder formed in the body of the gauge. Fig. 3 shows the invention applied to a limit screw-thread gauge. The body a is recessed and screwed to receive a member d coned on the inside, as is also the inner end of the anvil b, a steel spherical part f being embraced between the coned ends. A bolt passes with clearance through the parts d, f and screws into the anvil b, the head e bearing against a shoulder on the body. The head of the bolt is slotted and may also have formed in it two holes through which a suitable tool may be passed to engage slots d' in the parts d and thus turn the bolt and the part d together. The part d forms an abutment, and the part f allows back-lash to be taken up, and also forms a resilient body allowing a very fine adjustment in the dimensions of the gauge-gap. A lead or like washere h is expanded into a recess d' after the gauge has been adjusted to seal the gauge. Flats formed near the gauging ends of the anvils engage flats formed on a projection g of the body to prevent the anvils turning. In a modification, the anvils are assembled from the outer ends of the holes through the body, and flats are cut on the anvils to engage flats formed on members secured to the part g after the holes for the anvils have been bored.

A root-crop harvester comprises a share 3 oscillating in a plane parallel to the direction of motion of the machine and an endless elevator 23, behind the share, both driven by the power take-off of a tractor which carries the machine. The machine comprises a frame 1 attached to tractor draught-links 51 and provided with screw-adjusted ground-wheels 45 which control the working depth of the share. The share is channel-shaped and has upstanding side-plates 4 secured to a transverse tube 8 pivoted on an axle 2. An arm 9 fixed to the tube is rocked by a connecting rod 10 attached to an eccentric on a shaft 11 driven by a jointed shaft 15 connected to the tractor power take-off. The shaft 15 also drives the elevator 23 through a belt transmission 15A, 17, 20 to the rear spindle 21 of the elevator. The rear end of the arm 9 rocks a shaft 13A through a crank 13. The rocking shaft 13A oscillates a finger 40 about a vertical axis, through links 42, 43, 44, and oscillates a lever 30 and shaft 26 about the axis of the shaft 26, through the links 32, 32A. The finger 40 assists in breaking up lumps and spreading the excavated material evenly across the elevator. The oscillating shaft 26 carries arms 25 on the ends of which are rollers 29 which contact the undersurface of the elevator to oscillate it. Further rollers 36 on arms 34 alter the amplitude of oscillation of the elevator surface by lifting it away from the oscillating rollers 29, this action being controlled remotely by a lever 39. The side-plates 4 of the share are extended by inclined members 6 which converge inwardly and carry guide-bars 7. Specifications 735,719 and 735,721 are referred to.
