Title: Improvements relating to labyrinth seals in turbines or compressors
IPC: F01D11/02
Filed: 1958-03-25
Abstract: 816,288. Stuffing-box substitutes; elasticfluid turbines. GENERAL MOTORS CORPORATION. March 25, 1958 [March 25, 1957], No. 9626/58. Classes 110 (3) and 122 (5). A labyrinth seal between the rotor and stator parts of a machine such as a turbine or compressor comprises a rotary ring 21, Fig. 2, and a non- rotary ring 31 mounted so that it can move transversely of the rotational axis of the machine in order to accommodate out-of-centre movement or distortion of the rotary ring. As shown applied to the interstage sealing of an axial-flow compressor, the non-rotary ring 31 comprises a web 32 and flanges 33 resiliently sprung into engagement with the walls 26 of a ring 24 which is brazed or welded to the inner shroud ring 23 of the stator blades 13; the blades are each provided with a tang 27 for welding to the rings 23, 24 and are attached at their outer ends to an outer shroud ring. The web surface 32 may be provided with a wear band 36 of a soft metal such as silver or soft aluminium in order to form the sealing surface which coacts with labyrinth ribs 22 provided on the ring 21 formed on the rotor; the ribs may, alternatively, be formed in the seal ring 31 or on both rings. In order to facilitate assembly of the stator and seal ring, the outer and inner shroud rings and the rings 24, 32 are split at 29, Fig. 3, into two halves, the halves of the seal ring 32 being connected such as by a flange 37 provided on the ends of each half and riveted together. The ring 32 which is prevented from rotation by bosses 41 welded to the ring 24 on each side of the flanges 37 for abutment therewith, may be centred with respect to the ring 24 by leaf spring 42. In the modification shown in Fig. 4, the seal ring 56 is resiliently held between the sprung ends 59, 61 of two separate rings 53, 54 which are welded to an inner shroud ring 52. The ring 56 is split into two halves connected by bolts passing through flanges 62 in the ends of the two halves. Rotation of the ring 56 is prevented by the abutment of the flanges with the sides of a slot 66 provided in the ring 54. In a further modification, the seal ring is of L cross-section and one of its arms is resiliently held between an annular spring flange and its supporting flange which is welded to the inner shroud ring. The latter seal ring, which is split and connected by bolts passing through flanges, is prevented from rotation by a pin fixed in the support flange and engaging with a slot formed in the ring. The latter pin-and-slot arrangement and the wear band 36 may be applied to all the embodiments.

Title: Method and a device for feeding weft thread into gripper shuttles in a loom
IPC: D03D47/00
Filed: 1965-03-08
Abstract: 1,103,241. Shuttleless looms. ELITEX SDRUZENI P O D N I K U TEXTILNIHO STROJIRENSTVI. 8 March, 1965 [10 March, 1964], No. 9661/65. Heading DIE. As the shuttle box 3 comes forward with the sley 1 a needle 21 contacts the weft 13 and is deflected so that when a lever 18 is rocked contacts 24, 25 remain open and the loom is not stopped, further forward movement of the sley 1 impinges the shuttle upon a weft feeder 11 which opens a weft clamp 8 to release the just laid weft end which is removed from the shuttle by the now possible pivoting of the needle 21, the shuttle then starts to rotate with the shuttle box and a previously laid weft end that is through the feeder 11 is drawn between the clamp 8 and a shuttle part 7. When the shuttle has rotated clear of the feeder 11 the weft through the feeder 11 is firmly clamped in the shuttle and shears 15 operate to sever the weft, the shuttle then rotates to a total of 180‹ and the shuttle is picked to the other side of the loom for a similar process to be repeated.

Title: Improvements in electric protective arrangements
IPC: H02H7/22
Filed: 1940-06-03
Abstract: 541,419. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd.. TRENCHAM, H., and MORTLOCK, J. R. June 3, 1940, No. 9680. [Class 38 (v)] [Also in Group XXXVI] In a sensitive arrangement for indicating or protecting against insulation-faults in bus bars of metal-clad switchgear, such as polyphase gear, the conductive coverings of individual sections of bus-bars (the insulation of which is indicated by condensers) are connected through resistances Rc to a common point X which in turn is earthed through a common resistance R. With an insulation failure, the voltage-drop across the appropriate resistance Rc renders the associated valve V1 conductive. When voltageunbalance caused by a through-fault occurs, currents flow in all the resistances Rc but undesired operation of all the valves V1 is prevented by the current in-the resistance R which is adequate to render valve V2 conductive and the current therethrough sets up across resistance P a voltage which is applied to the control electrodes of valves V1 and renders them non- conductive, the valves V1 being provided with delay-circuits D for ensuring this sequence of operations. The electron devices may be gas-filled, with the volt-drop applied between cathode and control electrode, the anode being fed with the alternating line-potential whereby the control electrode regains control during each negative half-cycle of anode voltage. The Provisional Specification refers also to protection of a cable and to the use of H.F. carrier currents, the sum of which nows in a resistance in the neutral connection. Specification 405,614 is referred to.

Title: Improved polyester resins
Inventor: SMITH KEITH BEADSMORE
IPC: C09D167/00
Filed: 1958-03-26
Abstract: A polyester resin, useful in wire varnishes, contains the residues of (1) terephthalic and/or isophthalic acid; (2) a saturated aliphatic triol; (3) ethylene glycol and (4) 1 : 2- and/or 1 : 3-propylene glycol; the molar ratio of triol to diols being from 2 : 1 to 1 : 3 and the molar ratio of ethylene glycol to propylene glycol being from 5 : 1 to 1 : 2.  The resin is made by reacting a lower alkyl ester of the acid with excess of the alcohols, if desired in the presence of a solvent (e.g. white spirit, toluol, xylol, high boiling hydrocarbon fractions, polyhydroxy benzene derivatives, cresols or xylenols). Wire enamels comprise a solution of the polyester in a solvent together, if desired, with a metallic soap or salt (e.g. zinc acetate or naphthenate), or a masked isocyanate.  In examples wire varnishes were made by reacting dimethyl terephthalate, ethylene glycol, propylene glycol and glycerol in the presence of cresylic acid and zinc acetate, diluting the reaction mixture with cresylic acid and/or a hydrocarbon and adding either cobalt naphthenate or a phenol adduct of a polyisocyanate together with zinc naphthenate.

Title: Improvements in or relating to fastener inserting machines
IPC: A43D69/04
Filed: 1955-04-05
Abstract: 781,017. Nailing. BRITISH UNITED SHOE MACHINERY CO., Ltd., and JAMES, C. H. April 3, 1956 [April 5, 1955], No. 9873/55. Class 89(3) A fastener forming and inserting machine includes a pair of wire shearing members which have a pair of co-operating shearing edges which act to sever a pointed fastener from a length of wire, and also includes wire bending means for laterally displacing a portion of the wire across the shearing edges so that the shearing edges must shear through the displaced portion of the wire along an oblique line the beginning and end of which lie on the median lines of portions of the wire lying at opposite sides of the displaced portion, thereby forming symmetrical V-shaped points an the two severed ends of the wire. The illustrative machine is generally similar to the machine disclosed in Specification 22456/04 [Class 89] and includes a throat 5, Fig. 3, carried by a stem 9 rotatably mounted in a bracket 11 so that the throat may be turned from a position, shown in Fig. 2, wherein a wire 1 is fed into a passage 7 in the throat, to a position wherein a driver 12 can pass into the passage 7 to drive into the workpiece a fastener which is severed from the wire 1 during rotary movement of the throat 5. Prior to the rotary movement of the throat 5 the wire 1 is forced into a recess 17 in a stationary block 16 by means of a wire bending and gripping arm 21 which moves from the position shown in Fig. 3 to the position shown in Fig. 4. Shearing edges constituted by one edge of the recess 17 and by an edge of the passage 7, then diagonally bisect the offset part of the wire in the recess 17 so that upon the rotary movement of the throat 5, these edges sever the wire to form symmetrical V-shaped points on the upper end of the fastener in the throat 5 and upon the lower end of the wire which will provide the point upon the next fastener to be formed in the throat. The wire feeding means is similar to that disclosed in Specification 22456/04 and includes a feed wheel 107, Fig. 1, rotated bv a ratchet wheel 115 driven by pawls 117 which ride for part of the stroke over a shield 136 which can be positionally adjusted to vary the length of the fasteners. The position 'of the shield 136 is made dependent upon the thickness of the workpiece by means of linkwork coupling the shield 136 to the work supporting horn 153, but this link-. work can be uncoupled so that the shield 136 can be adjusted independently by means of a hand lever 137. The work is fed step by step by a foot 63 which engages the upper surface of the work and is secured on the lower end of a lever 65, which at its upper end is engaged by a crank pin 73 the throw of which may be adjusted in order that the distance the work is fed in each cycle of the machine may be varied. Specification 535,901 also is referred to.

Title: Line thickening processor
Inventor: KATAYAMA OSAMU
IPC: H04N1/387
Filed: 1987-01-07
Abstract: PURPOSE:To obtain a heavy line area of octagon near to a circular shape at the time of thickening of lines in the picture element of one point by alternately executing a lining by 8 neighborhoods and a lining by 4 neighborhoods. CONSTITUTION:The line thickening by the 8 neighborhoods and the line thickening by the 4 neighborhoods are alternately carried out. Namely, a neighbor position is obtained by position converters 105, 106, at this time, when the value of a frequency register 102 is an even number, the position converter 105 is selected and when it is an odd number, the position converter 106 is selected, the positions obtained respectively are outputted. Further, the values of the picture elements of these positions are examined by a control part 108 and the value of the picture element processed by the value is set. In this case, when the picture element of 1 is present in these positions, the picture element of a processed position is set to 1, but not in the positions, it is set to 0. This processing is carried out up to the right and lower point of the picture A of a completing position. When a position register 103 comes to the completion position by one lining, the frequency register 102 is subtracted by one. At this time, if the frequency register is not 0, the value of a start position register 104 is inputted again to the position register 103, and the above-mentioned operation is repeated.
