Patent GB-358467-A (GB)
Abstract: 358,467. Weaving figured fabrics in dobby looms. DEBOUTTEVILLE, M. D., 15, Avenue Sainte Foy, Neuilly, Seine, France. April 3, 1930, No. 10610. Convention date, Aug. 14, 1929. [Classes 142 (i) and 142 (iv).] To obtain an increased size of repeat for a given number of shafts, instead of threading these in succession in the usual regular order as shown for example for the shafts 1 .. 4 in Fig. 1, the shafts are grouped into sections and successive warp threads are threaded in some regular order into the successive sections A .. D, as shown by Fig. 4. The shafts in the sections are also threaded in regular order. Thus, as shown on the left of Fig. 4, with 20 shafts divided into 4 sections, a repeat only occurs after threading 48 warp threads. The shafts of a section receiving a warp thread are so selected that any combination of one shaft of each section receiving successive warp threads has no shaft in common with an adjacent combination. Throughout the weave one or more complete sections are raised as a whole to form the ground. In addition, one or more individual shafts of other sections are raised to form the figure. In a modification, the figure is formed by raising all the shafts of the sections weaving the ground with the exception of certain shafts. Designing woven fabrics.-As shown by Fig. 3, the order of threading of the warp threads through the shafts arranged in sections A to C containing 4, 6, and 4 shafts respectively can be represented by a broken line a, b, c, d, and the order of raising these shafts by a broken line m, n, o, p, the pattern resulting being that indicated at the bottom lefthand part of the Figure. It comprises a clearlydefined figure and subsidiary less clearly-defined ones. Healds ; jacquards ; lifting cords.-A harness which may be used for weaving by the method described comprises heald eyes a, Fig. 5, furnished with openings for the warp threads and each connected by cords c to a shaft a in each of two or more groups of shafts I, II. The shafts a are operated by a dobby, and have rods b resting on the cross-pieces i of a fixed grid comprising strips of wood drilled with holes j receiving brass rods. The heald eyes are connected to cords g passing through a lower grid k and weighted by lingoes h. The heald eyes e are threaded in some simple order, but the coils c are so connected up to the shafts a of at least one group, that the shafts in this group are effectively threaded in sections as described above. The shafts in one group may be used to form the figure and the shafts in another group to form the ground only, or each group of shafts may produce a pattern, the patterns being complementary to one another.

Abstract: 1448322 Mass spectrometers ROCHESTER UNIVERSITY OF 15 Aug 1974 [28 Sept 1973] 36031/74 Heading H1D A mass spectrometer for analysing a burst of ions, e.g. produced as a result of a laser pulse, according to their charge/mass ratio and independently of their velocity at entrance to the analyser, comprises means for generating a magnetic field or, as shown in Fig. 2, an electrostatic field which varies as a function of time elapsed in such a way that all particles having the same charge/mass ratio pass to respective conductive collectors where their abundance can be measured as a current. In Fig. 2 the electrostatic field is generated between plates 36 and 38 and a potential is applied which is an inverse function of the square of time elapsed from the start of an ion beam pulse as indicated by the detection of an ionizing laser beam pulse. It is shown that the ions of a particular charge/ mass ratio will pass through apertures 42 into conductive collectors 58 for measurement as currents in leads 62. A magnet surrounds the collectors 58 to suppress secondary electrons. Conductive rings 44, 46 connected to a potential divider 50 provide fringe field correction. A total current probe 76 is provided for calibration purposes. The voltage generator providing the required field function is illustrated in Fig. 5 (not shown). The laser pulse initiates via two monostable circuits (90, 92) an oscillator (94) whose output is counted at (96) and converted to analogue form by a decoder (98) and potentiometers (102). The analogue voltage is applied through an operational amplifier (108) to a cathode follower and amplifier thermionic valve stages (114, 116) the anode and cathode of the latter being connected to plates 38, 36. A spectrometer using a magnetic field is not described in detail but it is shown that the field flux density should vary as a simple inverse function of time elapsed.

IPC: H01M4/24
Filed: 1955-12-16
Abstract: 854,691. Batteries YARDNEY INTERNATIONAL CORPORATION. Dec. 13, 1956 [Dec. 16, 1955], No. 36212/55. Class 53 The high initial discharge voltage of an alkaline cell is reduced by incorporating in the positive electrode material a substantially insoluble halide of the metal of the positive electrode material. For a zinc-solver cell, a positive plate is. formed either by compressing a mixture of 100 parts. by weight of silver powder and 5-50 parts by weight of silver chloride powder or by processing a sintered silver plate in an electrolyte bath of hydrochloric acid or a solution of a soluble metallic chloride, e.g. sodium or potassium chloride, until the proportion of silver to silver chloride is the same as that in the compressed plate. The cell is subjected to at least one charge/discharge cycle before general use. The plate may also be produced in its charged condition by mixing silver oxide and silver chloride powder, with the proportion of silver to silver chloride in the above range. If a battery is formed of groups of parallelconnected cells, which groups are arranged in series, some of the positive plates of each group may be of silver only and some of a mixture of silver and silver chloride. However the correct proportion of silver to silver chloride should be present in each group and preferably the plates which contain silver chloride should be evenly distributed throughout the group.

Abstract: 1,139,933. Centrifugal separators. WESTFALIA SEPARATOR A.G. 12 Aug., 1966 [12 Aug., 1965], No. 36230/66. Heading B2P. In a centrifugal separator having a device for the discharge under pressure of at least one liquid component and sludge ejection apertures in the wall of its drum, partial desludging is carried out by opening the sludge ejection apertures at predetermined time intervals, or in dependence upon the volume of sludge in the sludge chamber of the drum, and subsequently closing the apertures when the pressure in the discharge line for the liquid component drops. Liquid material to be centrifuged enters the drum of a centrifugal separator 1 through a line 2. Clarified liquid is discharged' from the drum under pressure through a line 4 by means of a paring disc. Sludge is discharged from the drum into a receptacle 3 through apertures in the wall of the drum. The opening and closing of the apertures may be controllled by a sliding piston which is actuated to open the apertures by means of fluid medium introduced through a line 5. The line 5 has an electromagnetic valve 6 which is opened by a timer 7 at predetermined intervals or by a pulse generator which operates in dependence upon the volume of sludge in the drum. In operation, if, during opening of the sludge ejection apertures, the free liquid level in the paring chamber drops and the paring disc is no longer immersed in the rotating liquid, the pressure of the liquid in the line 4 drops. A pressure switch 8 in the line 4 then effects closing of the valve 6 by interrupting the electric current supply to the valve. Alternatively, the sludge ejection apertures may be kept closed by a member acted upon by a continuous supply of operating medium thtrough the valve 6. In order to move the member so as to open the apertures, additional operating medium is supplied through a valve 9 in parallel with the valve 6. In this case, the timer 7 opens, and the pressure switch 8 closes, the valve 9.

Abstract: 1514257 Lift operated fastening J W VON HOLDT 5 Sept 1975 36662/75 Heading E2A [Also in Division BS] A locking device for use with mould halves, particularly injection mould halves, comprises an anchor block 22, adapted to be secured to one mould part 94 by a screw 32, a retainer block 24, adapted to be secured to the other mould part by a screw 50, a pivot pin 60, a hoist bolt 70 carrying the pin, and a hook 64 on the retainer block adapted to receive the pin and lock the mould halves together when the hoist bolt is pivoted to a vertical hoisting position (see Figure 4). The pin is vertically slidable in slots 62 in the anchor block and a safety pin 80 is provided which, when the mould is mounted on a press, is pushed by an abutment surface 120 on the press, to a position (see Figure 5) in which it prevents the pin falling to the bottom of the slots and in which pivoting of the hoist bolt to a lowermost second locking position (see Figure 7) is prevented by the abutment of a pin 76 on the anchor block with a pin 78 on the hoist bolt. In a mould stored with the parting line 98 horizontal (see Figure 6), the hoist bolt pivots under gravity until the pins 76 and 78 abut to prevent further pivotal movement (the position shown in Figure 6) and the pin 60 is held lightly in engagement with the hook 64. When the upper mould half is lifted the hook cams the pin out of engagement with it thus allowing the upper half to be lifted, the camming action causing the hoisting bolt to pivot upwardly. In a second embodiment, see Figure 11, one half of the mould is provided with a projecting retainer pin 32 and the other half is provided with a locking sleeve 168, biased upwardly by springs 174, and movable downward over the pin to a locking position by means of a hoist bolt (142). The bolt is pivotable about a pin 160 carried by an anchor member 136 about which the locking sleeve is slidable. The sleeve may be moved to the locking position by the action of cam surfaces 166 on the hoist bolt as the bolt is either pivoted anticlockwise to a hoisting position (see Figure 9 not shown) or clockwise to a second locking position (see Figure 13 not shown). In a third embodiment, (see Figure 14) an upwardly spring biased locking sleeve 196 having locking points 198 on its lower edge is cammed downwardly into locking contact with the mould halves, by the curved lower end 222 of a hoist bolt when the bolt is pivoted to the hoisting position shown in the Figure.

Abstract: 805,289. Bridges, pontoon or land. ODOT, C. A. M. E. Nov. 30, 1956 [Dec. 1, 1955], No. 36694/56. Class 20(1) A pontoon bridge section on wheels 8 is packed up for transport as in Fig. 2 and is shown extended in the water in Fig. 4. Each section comprises a central floating box girder or caisson 2 to which are pivotally attached similar lateral caissons 3 to which may be added pivotally attached at 13 other stiffening girders 9 for holding additional inflatable floats 10 as required. The caissons may have propellers for water transport. To pack up the floats 10 are detached from the girders 9 which are folded at their hinges 13 alongside the caissons 3 to overlap each other. The caissons 3 along with the girders 9 are then swung up about hinges 4 to rest on top of the central caisson 2. The section can then be driven away, having its own engine 6. The caissons 3 have side recesses 14 to make a space for the wheels 8 when swung down into floating position. If the bridge sections are large however, each may be towed by an independent tractor provided with hydraulic means to pivot the sections 3 and 9 up and down as required. The sections may be adapted for use on dry land, Fig. 7, in which the caissons 2 and 3 are supported on trestles formed by using the girders 9 vertically with their bottom ends placed on sacks 26 of concrete mixture which adjust themselves to varying ground levels before finally setting. Adjustable screw piles may be used instead. In Fig. 6 the caissons, 2 and 3 rest on the girders 9 supported between the other trestle girders 9. Figs. 8 and 8a show the vertical level adjustment of the horizontal girders 9 in which lugs 29 are carried by a vertically adjustable plate 33, the lugs 29 being also pinned to like lugs on the horizontal girders 9. Rotation of a handwheel operates reduction gear to rotate sprockets of a rack shaft 32 attached to the plate 33 which is thereby moved up or down as required. Fig. 9 shows a self adjustment and self attachment of one bridge section to the next in which the right hand caisson 3 has an end-projecting finger 36 which becomes inserted in a socket 37 in a plate 38 secured to the next ahead caisson 3, after the right hand caisson 3 has been lifted. After release the bevel on 36 snaps under the bevel on 38 so drawing both caissons 3 towards each other. Sliding bars 39, Fig. 9, are received in horizontal recesses 40 to prevent relative vertical displacement. Fig. 10 (not shown) includes different widths of caissons combined together. The floats 10 are arranged to minimize any damming up of a river. In Fig. 11 (not shown) winches and pulley blocks are used to raise and lower the caissons 3. In Fig. 12 (not shown) each bridge element may be quickly set up as a crane for positioning the girders 9 as trestles on dry land, one of the girders 9 acting as the crane jib. Figs. 13 and 14 (not shown) comprise a land section attached to a floating section.
