Title: Improvements in or relating to armatures for ignition magnetos
IPC: H02K21/38
Filed: 1930-09-04
Abstract: 356,471. Inductor magnetos. FABBRICA ITALIANA MAGNETI MARELLI, 22, Corso Venezia, Milan, Italy. Sept. 4, 1930, No. 26416. Convention date, Sept. 5, 1929. [Class 35.] The stationary armature of an ignition magneto is provided at each end with a flange which forms on its periphery a supporting surface adapted to be located in a corresponding seat in the body of the magneto so that magnetic connection is ensured between the armature and the pole shoes in the magneto body. As shown, applied to a magneto having a stationary field system and a rotating flux distributer, the laminated armature core 1 has bent ends 3, 4. A U-shaped flange 5 over the end 3 abuts and is screwed on to enlargements 3<1> of the core end, Fig. 4, and surfaces 5<1>, 311 are machined on the flange and core end to fit the cylindrical or tapering surface of the seat 7 in the magneto body 8. The flange carries a spring 9 to engage on the surface of the magneto body. At the other end of the armature a flange 10 having a tapering rim engages in a tapering seat 23. This flange has a sleeve 12 through which passes a conductor 13 connecting the insulated end of the secondary winding with a contact concentric with the distributer support and contacting with the central contact 16 of the distributer. The distributer is carried by a gear wheel 15 rotating on ball bearings 14 on the sleeve 12. The core 1 and flanges 5, 10 are secured together by a strip 17 having upturned flanges 18, 19 riveted to the flanges. The armature structure is held in position by means of an expansible ring 21 having a tapering cross section fitting a tapering groove 22 in the magneto body.

Title: Improved melt spinning process for aromatic polyesters
Inventor: BREMNER JAMES DUNCAN
IPC: D01F6/62
Filed: 1969-05-23
Abstract: 1,268,908. Melt spinning aromatic polyesters. IMPERIAL CHEMICAL INDUSTRIES Ltd. 28 April, 1970 [23 May, 1969], No. 26429/69. Heading B5B. In a process for spinning an aromatic polyester comprising :-(a) extruding a filamentary stream at a controlled linear speed in the molten state, (b) cooling such stream from its initially molten state through an intermediate plastic state to a solid state, and (c) hauling off such solidified filament at a higher controlled linear speed, a method of reducing the optical birefringence of such solidified filament comprises: (i) applying a forwarding force to such filamentary stream in a region in which it is in such intermediate plastic state, (ii) the forwarding force being sufficiently small such that the filament tension between the point of application of the forwarding force and the point of hauling off is always positive. The forwarding force may be applied by at least one driven roller, which may be heated. The forwarding force may be applied by a fluid drag, e.g. by an air ejector. The polyester may be polyethylene terephthalate. As shown in Fig. 1 of the drawings, a spinning pack 11 with a spinneret 12 at its base, extrudes filamentary streams 13 which at first are subjected to delayed cooling in the region 14 which is partially enclosed in the thermostated box 15 used to heat the pack 11. An air ejector 16 surrounds the threadline at a point between the spinneret 12 and a spin finish applicator 17. The filaments are wound up on a bobbin 18. As shown in Fig. 2, a suitable form of air ejector comprises a short wide bore Venturi tube 21 held by a screw-thread in a casing member 22 with an air inlet duct 23 connected to a compressed air supply line 24 by a valve 25. Air is distributed round the Venturi tube in the chamber 26 and escapes through an annular slot 27. In operation a high-speed inward air flow through the annular slot 27 tends to bend downwards parallel with the wall 28 of the Venturi tube 21, thus entraining with it air in the upper throat 29 of the Venturi tube 21. This entrained air in turn applies a downward force to filaments passing through the Venturi tube.

Title: Improvements in or relating to carpet edging
IPC: A47G27/04
Filed: 1963-07-04
Abstract: 1,026,077. Securing carpets to floors. M. B. HUGHES. Sept. 30, 1964 [July 4, 1963; Oct. 9, 1963], Nos. 26546/63 and 39839/63. Heading A4S. [Also in Division B5] A carpet edging made from synthetic plastics material comprises a strip 1 formed with a lip 4 which, when the strip 1 is - mounted over a floor, can be prised up for inserting thereunder the edge of a carpet 3 and will clamp the inserted carpet edge under its own resilience. In one embodiment, Fig. 1, the edging comprises an extruded nylon strip 1 having a longitudinal channel 2 to receive the margin of the carpet 3. The lip 4 overlies the carpet 3 and a longer wall 6 is situated thereunder. The wall 6 may be wedge shaped, as shown. The edge of the strip 1 adjacent the closed end of the channel 2 is tapered to provide a ramp so that the edging is particularly suitable for use near doorways. The strip may be screwed, tacked or nailed to the floor. In a second embodiment, Fig. 4, the edging has a blunt edge to engage a wall. Flanges 7 may be provided to raise the strip 1 from the floor by the thickness of the underfelt 8. The channel bounded by the wall 6 and the flanges 7 can be used to conceal electric wiring. The flanges 7 may be omitted and a passage 9, Fig. 7 (not shown), is provided to accommodate wiring. In a modification, Fig. 8, to replace worn patches in carpets, two strips 1, formed with open channels 9 are positioned back-to-back. In a further embodiment, Fig. 5, the wall 6 is omitted and a flange 7a is secured to a wall.

Title: Automatic lubricant flow increase valve
IPC: F16D48/02
Filed: 1976-06-25
Abstract: 1501304 Change-speed control; lubricating clutches BORG-WARNER CORP 25 June 1976 [14 July 1975] 26625/76 Heading F2D To improve heat dissipation in a fluidactuated friction device of an automatic transmission during engagement of the device to effect a ratio shift, a valve providing a temporary increase of lubricant flow to the device is actuated in response to pressure of fluid exhausted from another friction device which is disengaged during the shift. When a 2-3 shift valve 38, in the portion of a control system shown, is in its lower position it directs pressure fluid from a supply conduit 310 through a conduit 316 and valve 42 to a brake B-1 to establish second ratio. Movement of the valve 38 to its upshifted position causes the brake to be exhausted through interconnected conduits 316, 318 and a conduit 218 leading to sump through a restriction 455, and a clutch C2, consisting of a piston 452 acting on plates 458, to be pressurized through a conduit 330, valve 52 and conduit 332 which has a connection 322 with an accumulator 48 to soften clutch engagement. The pressure of fluid exhausting from the brake acts through a conduit 442 on a plunger 422 of a valve 410 to displace a spool 416 to the position shown in which it connects a conduit 74 with a port 428 to supply fluid to a conduit 440 to augment the supply of lubricant from a conduit 446 to the clutch through ports 462, 464. Such augmentation is only temporary because falling pressure in the conduit 442 allows the spool to be reset by pressure in the conduit 440 acting on its lefthand end. Instead of the arrangement being such as to increase the pressure and flow in the entire lubricant system connected to the conduit 446 the system may be modified such that the valve 410 supplies lubricant to the clutch C2 at all times. In this case a land 420 would be smaller than a land 418, and the lubricant conduit 446 would not be connected to the conduit 440.

Title: Improvements relating to means for measuring the thickness of non-magnetic coatings on magnetic bases
IPC: G01B7/06
Filed: 1945-10-12
Abstract: 599,601. Thickness-gauges. BIRMING- HAM SMALL ARMS CO., Ltd., and SMYTH, C. N. Oct. 12, 1945, No. 26660. [Class 37] Relates to gauges for measuring the thickness of non-magnetic coatings on magnetic bases wherein the poles of' an A.C. electromagnetic probe are applied to the coating which then forms an air gap in the magnetic circuit formed by the magnet and the base. According to the invention, the probe magnet is embedded in a material, e.g. polystyrene so that the probe may be used in an electrolytic bath without damage to the probe by chemical action. Fig. 1 shows the electromagnet 1, 3, the enclosing polystyrene 5 forming a handle at 7 and providing only a very thin coating over the pole faces 9 so as to have substantially zero effect on the reluctance of the magnetic circuit. The probe is connected in an A.C. bridge circuit, Fig. 2 (not shown), with a similar probe, the poles of which are magnetically connected. The bridge output varies in correspondence with the coating thickness being measured and may be indicated directly on a milliameter actuated through an amplifier. The magnet may function alternatively as a transformer.

Title: Improvements in or relating to electrical modulation systems
IPC: H03C1/34
Filed: 1932-09-28
Abstract: 394,186. Valve modulating circuits; television and copying-telegraphy transmitters. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Artzt, M. ; Hotel Plaza, Camden, New Jersey, U.S.A.) Sept. 28, 1932, No. 26945. Convention date, Nov. 20, 1931. [Classes 40 (iii) and 40 (v).] A valve modulating circuit, particularly intended for picture telegraphy or television, comprises two tetrode or like valves with a carrier wave applied in phase opposition to corresponding grids, and with the modulating potentials applied to another grid of one only of the valves so as to upset the carrier balance in the joint plate circuit. The carrier source 31 is coupled through leads 11, 12 to the outer grids of the tetrode valves, which are given a low positive voltage by a battery 30 connected to an intermediate point on a resistance 10 placed across the leads 11, 12. The plates are connected to each other directly, and are given a higher positive voltage by an additional battery 19 connected through a high resistance or impedance 18. The inner grid 21 of the valve 14 is held at a steady negative voltage by a tap 22 on a potentiometer 23, 24. Signal voltages are applied to the inner grid 25 of the other valve 13 by a photo-cell 27 in circuit with a battery 28 and resistance 26. When there is no signal, the carrier wave is balanced in the plate circuits, and no carrier voltage appears across the resistance 18. A signal disturbs this balance, and the resultant voltage across the resistance 18 is applied to an amplifier 33 whence it may pass through a filter 34 to a further amplifier 35. It may then, in combination with a synchronizing wave from a source 37, be applied to a radio transmitter 36. By movement of a switch 39 from contact 20 to contact 38, the carrier is balanced for maximum, instead of minimum, light intensity on the cell. The carrier source 31 may be coupled to the outer grid circuits by a transformer with centretapped secondary, instead of resistance 10 ; and the balance is then effected by a switch selecting contacts on the bias resistance 23. - The source 31 may be of audio frequency, and the modulated signals from the amplifier 33 may be transmitted over a line. -Alternatively, the source 31 may be of radio frequency and the modulated signals from the amplifier 33 may be radiated directly. A microphone, or other source of audio currents may be substi.- tuted for the photo-cell 27.

[Class 17 (ii)] Relates to shoes of the kind wherein an upper lasted over an insole on a last is held in lasted position by partly driven tacks which, with the exception of those at the heel seat, are withdrawn after setting of the cement which secures the upper to the insole, and an outer sole is secured by stitches which pass through the upper and insole, and consists in employing a composite insole comprising an inner thin layer of flexible leather and one or more outer layers of less flexible material secured together before assembly on the last, and in making the upper substantially flush with the outer surface of the insole to avoid bottom filling by skiving its edges. The insole may comprise a thin inner layer a of flexible leather and an outer layer b of less flexible leather of substantially the same shape and size glued together centrally so as to leave a channel around the edges. The outer sole may be similarly constructed. Alternatively, the outer layer b may be of rigid composition and glued along its whole length which covers the heel seat and shank, or the layer b may be of leather slightly less flexible than the layer a and cover the heel seat and shank portions, and a shank-stiffener may be clamped at each end to the layers.

Abstract: 950,820. Cyclones. CHARBONNAGES DE FRANCE. July 17, 1962 [July 20, 1961], No. 27495/62. Heading B2P. Dust particles entrained with gases from a fluidized bed 7 of granular solids in a reactor 1, Fig. 1, are recovered in at least one cyclone 6 from the bottom of which they are removed through a collector tube 8 opening directly into the main stream of the granular solids evacuated from the bed 7 in such manner that the dust particles have a preferential flow with respect to the granular solids, the pressure at the delivery of the tube 8 being maintained at a lower value than that at its junction with the base of the cyclone, thereby ensuring in the tube 8 a downward flow of gases carrying the dust particles. The granular solids are fed at 2 and overflow through a spout 5 which is extended by a wall 10 to form a chamber 11 in which is arranged a bell 12. The tube 8 passes through the bell and has its extremity level with the base thereof. The gases are drawn off from the bell by an ejector 13 which directs them to atmosphere or returns them to the reactor or to its outlet with or without previous de-dusting. Alternatively, the bell may be evacuated by connecting it to a chamber into which a pressure lower than that at the base of the cyclone exists. In a modification, the collector tube 8 is provided with an ejector to aid in the evacuation of the dust particles and the gases are ejected from the bell directly into the reactor above the bed 7. In Fig. 3, the collector tubes 8 A , 8B of a multi-stage arrangement of cyclones are led to the base of bells 12 A , 12 B  which open in the evacuation spout 5. In a further modification, the collector tubes of an assembly of multi-cyclones inside the reactor open on the top of a funnel-shaped casing from the bottom of which a main collector tube fitted with an ejector extends to open at the bottom of a bell from which the gases are ejected into the reactor. In Fig. 5, the bell is dispensed with and the gases with the dust particles passing from the tube 8 flow through the layer of evacuated solids which act as a filter for the dust particles while the gases escape through a fine-mesh sieve 17 towards the fluidized bed 7.
