Patent GB-1016859-A (GB)
Title: Self-priming axial-flow pumps
Inventor: RICHARDS JOHN ALAN
IPC: F04D3/00
Filed: 1964-07-09
Abstract: 1,016,859. Axial-flow pumps. CASCADE CORPORATION. July 9, 1964, No. 28352/64. Heading F1C. A self-priming axial-flow pump comprises a casing housing the impeller and formed so that a body of the liquid to be pumped is at all times available to the impeller as a priming liquid, and a stationary diverter contained within the casing in a discharge passage and formed so as to interrupt impeller-induced centrifugal motion of a fluid composed of the priming liquid mixed with air drawn by the impeller from the suction side of the pump and to lead the fluid to a zone relatively free of impeller-induced turbulence occupying a level no lower than the discharge end of the impeller and from which the contained air is free to escape by ascension. In the pump shown in Fig. 1, liquid is drawn through a suction pipe 16 into a chamber 14 and thence through a non-return valve 15 and a filter 17 to the pump casing 11, where it is acted on by stationary guides 23 and impeller blades 20. During priming, air from the suction side of the pump becomes mixed with the liquid. Transverse baffle plates 30, 35 at the pump outlet suppress the whirl component of the velocity of the mixture and therefore prevent centrifugal separation of the air from the liquid whereby separation does not occur until the mixture reaches a relatively calm zone containing liquid which is relatively free from air. The air then separates out under gravity and escapes through the pump discharge. As shown for the baffle 35, the baffles 30 and 35 may be perforated or slotted in whole or in part. In a modification, Fig. 9, the liquid discharge pipe 32<SP>1</SP> extends from the bottom of the pump casing, with a U-bend to provide a trap in which air-free liquid collects during priming. The air separating out above the baffle plates 30<SP>1</SP>, 35<SP>1</SP> escapes through a check valve 51 a which may be arranged to close in response to the rise of discharge pressure which occurs as priming is completed. Alternatively, it may be closed by a float or by a control handle 52. Figs 10 and 11 show a pump having a volute casing 60 at the discharge side. The mixture is guided upwardly between baffle ribs 70 and 72 and, after reaching a chamber 67, a major part of it returns downwardly along a passage 74. The large crosssectional area of the passage 74 slows down the mixture to allow the entrained air to escape. Guide vanes 63 are held in place by a tapered spring-pressed ring 65 which bears upon tapered plates 64 which each carry a vane 63. The pump shift may be vertical instead of horizontal.
Patent GB-929818-A (GB)
Title: Hydraulic actuated borehole drilling apparatus
IPC: E21B44/00
Filed: 1961-08-04
Abstract: 929,818. Boring earth &c. JERSEY PRODUCTION RESEARCH CO. Aug. 4, 1961 [Sept. 13, 1960], No. 28384/61. Class 85. [Also in Group XXIX] An hydraulically actuated drill collar 26 has resiliently mounted anchors 74 engageable with the wall of the hole, and encloses means by which the drill bit 21 carried by a rotary member 20 fixed to the drill string may be forced against the bottom of the hole. Drilling fluid is pumped down a bore 23 in the member to the bit and through nozzles 24 so that the fluid pressure in the bore is greater than that in the annulus 25 outside the bit. Some of the fluid from the bore passes through ports 96 and is directed by an annular slide 84 (having an initial position as shown in Fig. 6) into a duct 100 to a chamber 68 to force the anchors into engagement with the wall. Pistons 40, 49 on the member, initially at the tops of their strokes in the chambers 38, 46, are moved downwardly with the member by fluid from the duct 100 passing through ports 106, 104 after the anchors engage the wall. As drilling proceeds the slide follows the member and a cage 80 fixed to the slide by a resilient sleeve 90 engages a shoulder 120 on the collar so that after further drilling the spring fingers 94 on the slide are released from a projection 116 on the member by a surface 83 on the cage. The latter part of the downward movement of the slide distorts the sleeve so that the slide snaps upwardly on release of the fingers 94 to engage its fingers 92 with a projection 114 on the member. The duct 100 is then vented to the annulus through openings 82, 63 to release the anchors 74, and fluid from the bore passing through port 96 is directed by the slide into a duct 110 and through a port 112 into the chamber 46 to move the collar downwardly until the cage engages the upper part of the chamber 62 and the latch fingers 92 are released from the projection 114 (see Fig. 9) to permit the slide to snap downwardly to return to the position shown in Fig. 6 at the beginning of a cycle.

Title: Improvements in rosin soap lake pigments
IPC: C09B63/00
Filed: 1930-09-23
Abstract: Oil and water-insoluble lakes of a substantially insoluble or difficultly water-soluble monazo-monosulphonic acid dyestuff containing about 15 to 50 per cent of insoluble rosinate, are prepared by forming the insoluble metallic compound of all or part of the azo dye, and or of all or part of the rosinate, incorporating the treated dye with treated or untreated rosinate, or the treated rosinate with treated or untreated dye, in all cases before development of the pigment, and then, if necessary, incorporating sufficient metal compound to complete the formation of a precipitate comprising the metal compounds of dye and rosinate, after which the pigment is developed by boiling under non-acid, preferably alkaline conditions.  The insoluble metal compound of the dye may be formed in any suitable way including the formation of a metal salt of one of the azo-dye components prior to the coupling of the components.  The rosinate as soluble salt may be incorporated therein prior to, during, or after such coupling.  The rosinate as insoluble metal salt may be incorporated prior to, during, or after the coupling of the azo-dye, and the latter then converted into the insoluble metal salt and developed.  Prior incorporation of the insoluble metallic rosinate may also take place in the coupling of a metal compound of one azo-dye component with the other component.  Or separate precipitation of the metal compounds of dye and rosinate may take place, and the two substances mixed prior to development. The products possess the characteristics of those of the parent Specification.  In examples (1) 1-sulpho-2-naphthylamine is diazotized and coupled with b -naphthol (Lithol Red), barium rosinate is added, and then a solution of barium chloride; the mixture is then boiled: (2) Lithol Red is first treated with barium chloride, rosin soap is added, and the mixture precipitated by adding barium chloride; the pigment is then developed: (3) Lithol Red and rosin soap are treated separately with barium chloride and the precipitates mixed and boiled: (4) the process of (1) is carried out using calcium chloride instead of barium chloride: (5) the process of (2) is carried out using calcium chloride instead of barium chloride: (6) the process of (1) is modified by adding the barium rosinate to the b -naphthol prior to coupling: (7) m-sulpho-p-toluidine is diazotized and coupled with b -oxynaphthoic acid, para soap and calcium rosinate are added, and precipitation completed by calcium chloride; the mixture is then boiled.  Instead of alkaline earth metal salts there may be used derivatives of strontium, magnesium, lead, or copper.

Patent GB-344338-A (GB)
Title: Improvements in and relating to joints for artificial limbs
IPC: A61F2/60
Filed: 1929-09-19
Abstract: 344,338. Joints for artificial limbs. DESOUTTER, C. and DESOUTTER BROS., Ltd., 73, Baker Street, London. Sept. 19, 1929, No. 28427. [Class 81 (ii).] A joint for an artificial limb comprises a pivot or pin 12, Fig. 1, attached to one of the members 13 to be joined, a block of rubber or like resilient material 14 mounted on the pivot, a second member 16 having an aperture 17 which fits over the block 14, the thickness of the apertured member being less than the length of the block, and means, such as a clamping nut 19, for maintaining an axial pressure on the rubber block, thus spreading the rubber block on each side of the apertured member 16 and causing the rubber to grip firmly the surfaces of the apertured member and the pin 12 so that only movement permitted by the molecular give of the rubber takes place. Alternatively, a block of such size that it has to be stretched before the apertured member can be placed in position is employed, the tendency of the block to revert to its normal shape producing the necessary pressure. The surfaces of the rubber block or the parts with which these surfaces come into contact may be serrated or roughened to increase the gripping action. The block may be given a double conical form as shown in Fig. 5, the apertured member thus taking up a central position more readily. In a modified construction the member to which the pivot is attached has a forked structure the apertured member being located between the arms of the fork and the axial pressure being produced by causing the arms of the fork to move towards each other. Fig. 8 shows a stirrup for suspending the bucket of an artificial leg comprising a joint 25 of the kind shown in Fig. 1, the pin projecting from the bucket 26, a stirrup 27 having forked members 29 between which a pivot pin and rubber block are located and an apertured member 28 located on the rubber block. Specification 327,139, [Class 81 (ii), Medical &c. appliances], is referred to.

Filed: 1967-06-20
Abstract: 1,186,922. Selective printing. RECOGNITION EQUIPMENT Inc. 20 June, 1967 [27 Feb., 1967], No. 28442/67. Heading B6F. [Also in Division G4] A document bearing human-readable symbols has corresponding simplified bar-code symbols applied to it. Printed symbols on documents are sensed by a mosaic of photo-cells for recognition purposes, the recognition apparatus controlling printing of a bar code on the document for each symbol to control a subsequent document sorter. The document sorter may optically sense bar codes printed in two different colours simultaneously and separately and to the exclusion of irrelevant markings by use of optical filters and a dichroic lens. Printing of bar code.-A stream of fluorescent ink is projected through a fine nozzle 107 from a pipe 104 subjected to oscillation magnetostrictively 105 (or piezoelectrically) so that the stream breaks up into separate droplets. The droplets are then electrically charged 109 by selective amounts so that electrostatic deflection plates 110, 111 deflect them as they fall under gravity on to the document 100 which is moving skew to the direction of the field from the deflection plates. Uncharged droplets fall undeflected into a waste trough 112. In this way a series of bars is recorded, each parallel to the width of the document If printing is done in two colours the above printing arrangements are provided twice, once for each colour. Feeding of documents is done using stack magazine feeders and endless moving belts between which the documents are gripped, vacuum drums being provided at the symbol and code sensing stations. Reference has been directed by the Comptroller to Specification 1,059,086.

Title: Improvements in and relating to cutter balancing apparatus
IPC: G01M1/12
Filed: 1947-10-25
Abstract: 629,206. Adjusting centre of gravity. ROBINSON & SON, Ltd., T., and WESTWOOD, A. Oct. 25, 1947, No. 28570. [Class 97 (iii)] Apparatus for balancing the cutters used in cutter blocks of wood-working machinery comprises a pivoted balance arm having supports at one end for the cutters in various positions and at the other end having adjustable balancing members and a movable part of a balance indicator co-operating with a fixed part on the apparatus. Preferably the adjustable balancing members comprise removable weights and screws with adjustable nuts for fine adjustment and the movable part of the balance indicator is in the form of a plate or dial moving with the balance arm over a pointer fixed on the end of an arm secured to the base, the pivot arm being secured to a transverse support mounted on knife edges in side supports integral with the base. The support for the cutters 25, Fig. 6, provided at the end of the arm 14, remote from the balancing members, preferably comprises a platform 22 having upright arms 23, the platform extending to either side of the arms and a notch 24, Fig. 8, being provided centrally between the arms. In use a pair of cutters is selected of identical dimensions and as nearly as possible equal in weight and the first is balanced with one end A<SP>1</SP> abutting the arm 23. It is then replaced by the second and the end A<SP>1</SP> of the heavier marked, e.g. with chalk. The operation is repeated with the other end A of each cutter abutting the arms 23. The cutters are then compared in the position shown in Fig. 6 and then with their cutting edges abutting the more remote of the arms 23. In all cases the edge of the heavier cutter at right angles to the arm 14 and remote from the pivot of the balance is appropriately marked. The cutters are then compared in the position shown in Fig. 8 and subsequently in similar position but inclined outwardly so that their faces abut the remoter arm 23. In these two comparisons the face of the heavier cutter further from the fulcrum is marked. From the markings it is possible to ascertain from which parts of the cutter metal is to be removed so that it is accurately balanced with its pair, the amount of metal to be removed may be ascertained by noting in each operation the amount of small nails required to balance the lighter cutter to the heavier.
Patent GB-419479-A (GB)
Title: Improvements in the recovery of sulphur from hydrogen sulphide
IPC: C10K1/00
Filed: 1933-10-16
Abstract: <PICT:0419479/III/1> Sulphuretted hydrogen is removed from mixed gases by converting it to elemental sulphur by means of a reaction with sulphur dioxide which is obtained by the combustion of one-third of the hydrogen sulphide content.  In the apparatus shown the gas to be treated enters, by a pipe 11, the base of a washing tower 10 down which flows an aqueous solution of sulphur dioxide from a pipe 13, the dioxide being present in such amount as to react with two-thirds of the hydrogen sulphide passing through.  The gases leave the tower by a pipe 12 and pass through an absorber 14 down which is fed from a pipe 15 a solvent for the remaining hydrogen sulphide of the type triethanolamine and water which will release the absorbed gas at a higher temperature as described in Specification 344,786.  A pipe 18 conveys the solvent, by way of a heat exchanger 20 and a pipe 21, to the top of a tower 17 heated by a steam coil 22 whence the hydrogen sulphide evolved passes by a pipe 30 to a burner 31 from which the sulphur dioxide formed is conveyed to a tower 34 where it is absorbed by water falling from a spray 35.  From the base of the tower 34 the solution is pumped through the pipe 13 to the top of the tower 10 from the base of which it is withdrawn by a pump 42 and passes to a filter 43 where the sulphur is separated, the water passing to the spray 35.  The water may contain an electrolyte to prevent the sulphur from remaining in the colloidal form.  In a modification, the whole of the hydrogen sulphide is removed from the mixed gases after which one-third is burnt and caused to react with the remainder.  The Specification as open to inspection under Sect. 91 comprises also a modification in which the gas mixture is first treated with the absorbent to remove the requisite hydrogen sulphide which is recovered and burnt to sulphur dioxide.  This subject-matter does not appear in the Specification as accepted.
