Patent GB-873880-A (GB)
Title: Improvements in chromatography tanks
Inventor: SHANDON ERNEST ROBERT
IPC: G01N30/94
Filed: 1959-04-02
Abstract: The chromatography tank incorporates a cylindrical glass vessel 1 having a closed flat bottom end and an enlarged upper inverted bell-shaped end 2 forming an open mouth.  The vessel is arranged to stand on any appropriate support surface with the aid of a wire supporting frame 3.  The internal shaping of the vessel, as a result of outwardly belling or <PICT:0873880/III/1> flaring the mouth, serves to provide a seating within the mouth for a glass solvent trough in the form of an endless or annular channel member 6.  This channel member 6 has upstanding substantially cylindrical inner and outer walls, the outer wall being appreciably deeper than the inner wall, and is open through the centre at 7.  The rim of the outer trough wall is conveniently provided with indents 8 at intervals to form locating valleys for adjoining rods 9 and 10 which act respectively as support and anti-syphon rods for a strip of filter paper which can be held with one end in the trough by a glass clamp or weight 11, passed over the rods 9 and 10 and thence suspended in the vessel 1 through the trough opening 7.  To ensure satisfactory sealing of the vessel mouth, the mouth rim 2a may have precision ground edges and the closure plate 12 may have a co-operating border or annulus.  The tank can be used for both ascending and descending chromatography and, in the former case, the trough may be employed merely to support the filter paper rods whilst solvent is poured either directly into the bottom of the vessel 1 or into a glass solvent dish which may rest in the bottom of the vessel in known manner.

IPC: B63B25/12
Filed: 1960-03-31
Abstract: 895,663. Tankers. CALIFORNIA TEXAS OIL CORPORATION. March 31, 1960 [March 7, 1960], No. 11357/60. Class 113. A tanker comprising wing and floor tanks 38 and 42, for liquid cargo or ballast, and holds containing independent thermally insulated tanks 32, liquified gas, has provision for maintaining the pressure in the tanks 32 at approximately atmospheric pressure, without venting the tanks to atmosphere, and for agitating the liquefied gas in the tanks to prevent thermal stratification. Abnormal amounts of vapour occurring in the tanks 32 are condensed by the refrigeration unit 230 and the formation of vacuums may be prevented by the generation of vapour in the vapourizer 276. Both units are automatically operable in response to a pressure sensitive cell 400. The contents of the tanks 32 may be agitated by circulation through the pumps 236 and nozzles 316. The construction and supporting arrangements of the insulated tanks 32 is described and also the handling arrangements for both types of cargo.

Title: Procress and apparatus for shaping tubes into frustoconical configurations
IPC: B31B50/59
Filed: 1977-03-17
Abstract: The tube blank is first of all sealed off fluid-tightly at the filling opening. It is then filled with compressed air and pressed snugly against the mating tapered inner wall of a die (13). The tube (12) formed in this way is checked for cracks, using the same compressed air, before being removed from the die. If there is a crack, the leakage loss activates an indication device or an ejector. The automation made possible in this way allows the potential of the production device to be fully exploited. <IMAGE>

Title: Improvements in or relating to a three-dimension contour producing machine
IPC: B23Q35/18
Filed: 1954-04-21
Abstract: 763,220. Copy-milling. CINCINNATI MILLING MACHINE CO. April 21, 1954 [July 9, 1953], No. 11476/54. Class 83 (3). A three - dimensional copying - machine comoruses a tool 25 movably supported on a cross-slide 18 on a main slide 12 of the machine, a first tracermechanism 66, 75 carried by the bed and co-operating with a pattern 76 on a support 100 carried by the cross-slide, and a second tracer-mechanism 37 on the cross-slide cooperating with a second pattern on a support 53 mounted on the bed, one of the tracer-mechanisms 66, controlling the movement of the two slides and the other, 37, the position of the tool on the cross-slide. The cross-slide 18 carrying the motor 26 driving the milling- cutter 25 is moved by a hydraulic ram 20 on the main slide 12 moved by a hydraulic-ram 14. The depth-control tracer 39 is mounted on a slide 33 moved on the slide 18 by a hydraulicpiston 30 in a cylinder 29. An arm 34 on the slide 33 moves the cutter 25 in unison with the tracer. The tracer 39 is adjustable horizontally by a.slide 35 and a transverse slide 36. Movement of the tracer 39 according to the pattern on the fixed support 53 admits pressure to the cylinder 29, to raise or lower the tracer and cutter. A cam, operated by a piston formed with rack-teeth and moved by hand or by pressure in a line 62 under the control of the profiletracer, may override the tracer 39 to raise the cutter-and-tracer slide 33. The profile-tracer 75 and associated mechanism is mounted on the bed 10 and is of the type described in Specification 763,219, except that excessive upward movement of the tracer controls an auxiliary valve to raise the slide 33 as referred to above. The deflections of the tracer 75 control the movements of the pistons 14, 20 of the main slide 12 and cross-slide 18, by way of adjacent parallel control valves. The work 86 is a rotor having nozzles 89 to be machined, the nozzles being of oval shape with raised rear lips. The rotor is positioned by a forked-rod 92, advanced by rack-and-pinion gearing by a hand wheel 97 to embrace a nozzle. The pattern 76, secured on the arm 100 by a clamp 102 gives the oval outline shape of a nozzle and the other pattern gives the lip shape. A hand-control-wheel 103 brings the pattern 76 and tracer 75 into contact. The machine has start, stop, spindlecontrol, and rate-controlling buttons 105 to 108. Specification 578,883 also is referred to.

Title: Device for unwinding material from a reel
IPC: F16D49/16
Filed: 1957-04-09
Abstract: 852,203. Unwinding devices. AUMANN, P. April 9, 1957, No. 11536/57. Class 120(2). [Also in Group XVI] A device for unwinding material such as wire or strip from a reel comprises a guide-roller 24 for the paid-out material which can change its position according to the tension of the material, a stop-brake 6 having a pivotally-mounted twoarmed lever, one arm being operatively connected with the roller so that the brake is lifted in normal operation but acts to stop the reel when the tension on the material ceases, and the other arm being operatively connected to a tensioning-brake 17 so that it maintains a constant tension in the material. The roller 24 is carried by an arm 23 fixed to a shaft 21 carrying a.rocker 22 engaging a track 8 on an arm of the brake 6: when the material is tensioned, the brake 6 is lifted off a drum 2 to tension a compression spring 12 on a rod 11 between a fixed part 14 and an adjustable nut 13, so that when the pull on the roller 24 ceases, the spring pulls the brake into engagement with the drum. The other arm of the brake lever is linked to a rod 15 in a bore in the tensioning brake 17, which is kept in light engagement with the drum by a compression-spring 18, which is weaker than the spring 12, and arranged on the rod 15 between the brake and an adjustable nut 19. With a moderate increase in the pull of the material, the brake 6 is lifted to reduce the effective force of the spring 18 partly to lift the brake 17 off the drum. When the pull is excessive, the brake 6 is lifted to such an extent that the force of the spring 18 is so reduced that a second spring 20 between the two brakes acts to lift the brake 17 off the drum altogether.

Title: Improvements in or relating to electric pulse circuits
Inventor: BARBER DONALD ROBERT
IPC: H03K3/45
Filed: 1962-03-27
Abstract: 945,084. Circuits employing bistable magnetic elements. STANDARD TELEPHONES & CABLES Ltd. March 27, 1962, No. 11627/62. Heading H3B. A circuit which may be used as a pulse distributer or as a shift register comprises a series of magnetic cores MC1 to, MC4, each having a shift winding such as SW2 connected to a transistor TR2 so that a clock pulse applied to the shift winding switches the core to the " 1 " state only if the transistor TR2 is enabled by the preceding core MC1 as the core MC1 returns from the " 1 " state to the " 0 " state. The transistors are normally biased to cut-off. The cores are normally biased to " 0 " by means of windings RS1 to RS4. As the cores are switched they give output pulses on windings OP1 to OP4. As a core MC1 is switched back to the " 0 " state a transfer winding TW1 enables transistor TR2. As shown, two phases of clock pulses are used but it is stated that only one phase is required if the cores reset fast enough and the transfer pulses last long enough.

IPC: D03C1/00
Filed: 1917-08-16
Abstract: 116,409. Taylor, W. H., and Dawson, H. Aug. 16, 1917. Figured fabrics.-Fabrics with a plain ground and a contrasting figure, or vice versa, are woven with a single weft and warps shed by two or more healds and jacquard harness, the warps being so drawn in that the combined actions of the healds and harness may produce a plain weave and, by a change in the harness treading relative to the regular action of the healds, may produce a contrasting weave, no warp remaining up or down for more than two picks. In one arrangement, heald warps a, Fig. 3, and harness warps b are drawn between the reed wires B of the lay A three in a dent, as shown, the drawing-in plan through healds 3 and harness 2 being shown in Fig. 4. The arrangement of the warps is such that a plain weave w, Fig. 5, may at times be produced, while at other times the warps in alternate dents may be shed together to produce the weave p; this shedding is shown in the third, fourth, and fifth dents of Fig. 3 and plain shedding in the other dents, the weft being shown at x. The change from the plain to the other weave may necessitate the floating of a warp over or under two shots of weft as at h and the raising of an extra warp at the edge of the figure as at k. The arrangement of the heald and harness warps may be reversed, and the warps may be drawn-in two in a dent and shed two, four, or five together at the figure parts.

Title: Improvements in and relating to containers
IPC: A24F15/00
Filed: 1947-05-02
Abstract: 628,893. Time locks. ROBINS, E. T. May 2, 1947, No. 11910. [Class 44] A container, such as a cigarette case, has timing means associated with the lock whereby it is automatically locked on closing, remains locked for a variable set period and is then automatically unlocked. The timing means consists of a spring adapted to be held stressed and a setting member movable from a zero position to a desired setting and preferably additionally stressing the spring in moving, the timed unwinding of the spring to return the setting member to the zero position being controlled by an escapement. The setting member carries means to unlock the case in the zero position and is associated with an externally visible indication of the time set and to elapse. The lower half of the case, part of which is shown in Fig. 4, carries a spring loaded pivoted catch 25 for co-operation with a latch on the upper half. The catch is apertured to pass the spindle of a setting head 23 and arranged to be released by pressing in the head. In the locked position inward movement of the setting head is prevented by a lever 42 abutting the face of a gearwheel 30 on the end of the spindle, the lever 42 being secured by engagement between a lug 43 and a catch 44 on a locking lever 45. The locking lever is moved to the released position by the projection 53 on a toothed setting wheel 51. The setting head 23 is connected through gear wheels 30, 31,33 and 38 with a sliding rack 20. The wheel 33 is displaceable and meshes with the wheel 38 only when the setting head is turned to displace the sliding rack from the zero position shown. Movement of the rack turns the setting wheel 51 and winds up the spring 55. The return movement of the rack under the spring 55 is regulated by an escapement mechanism 57 comprising a train of gears of which the first 58 is connected to the rack through a ratchet 62. The case remains locked until the rack has returned to the initial position in which the projection 53 displaces the locking lever 45, the time depending on the displacement of the rack from the zero position by the setting head. The rack is provided on the underside with markings 65, Fig. 1, visible through the window 63 in the front of the casing to indicate the time set and to elapse before the next unlocking. The rack may be automatically displaced from the initial position when the case is opened and closed. Specifications 623,325 and 628,892 are referred to.

Abstract: 701,566. Grinding and polishing glass. GLACERIES DE LA SAMBRE SOC. ANON. May 12, 1952 [May 16, 1951; April 10, 1952], No. 11998/52. Class 60 The grinding and polishing tools 3, 3<SP>1</SP>, Fig. 2, of an apparatus for simultaneously surfacing both faces of a continuously moving ribbon 1 of glass are removed for maintenance by imparting successively to a complete tool-supporting beam 4 or 5 a vertical movement and a horizontal movement to a maintenance station. Each lower beam 5 is provided with recesses to receive projections 43 on carriages 7 mounted for reciprocation on supports 10 which rest on a plate 11. When the beam is in its operative position, the plate is secured by hydraulically - actuated locking devices 14, Fig. 4. To remove the beam, the devices 14 are withdrawn by operation of a valve 20, and hydraulic cylinders 13, the piston rods 12 of which support the plate 11, are connected, to exhaust by operation of a valve 18 so that the beam is lowered on to a roller conveyer 42 and displaced by a tooth and dog connection with a travelling endless chain 44 to the maintenance station. Removal of an upper beam 4 is effected by hydraulic cylinders 49 which are controlled by a valve 53 to lift the beam on to a similar conveyer 50 the rollers of which are mounted on sliding or pivoted arms to allow the beam to pass. The vertical movements of the beams are guided by frames 6 provided with two sets of stops to limit the vertical travel of both upper and lower beams. In the operative position of the upper beam its supports rest on top of the cylinders 49 and no locking means are necessary. Instead of being laid directly on the conveyers 42, 50, the beams 5, 4 may be laid on transporter frames such as that shown at 58. Each beam removed for maintenance is replaced by another without stopping the apparatus. In an alternative arrangement, the upper beam is provided with hooks 83, Fig. 8, to enable it to be lifted, while the lower beam is removed by first lowering the tools 3<SP>1</SP> clear of the glass and then lifting the beam 5 by means of jacks 84 to disengage it from projections 93 on supports 82 which are displaced laterally to enable the beam to be lowered. The jacks are mounted on a transporter 85 which is in turn mounted on a carriage 86 travelling on a track 87. In a second alternative arrangement, the lower beam is fitted with lugs 94, Fig. 11, which rest on brackets 95 secured to a frame 92. Removal is effected by a travelling jack fitted with rollers which enable the beam to be moved endwise after it has been lifted until the lugs 94 are clear of the brackets 95 whereupon the beam is lowered. The jacks may be of the screw or hydraulic type. A series of beams for operation on both faces of the glass is provided, and the maintenance stations, which may be arranged either in or out of alignment with the beams, are situated at each end of the series. Specification 694,298 is referred to.
