Title: Improvements in or relating to devices for splicing wires
IPC: H01R43/00
Filed: 1929-07-05
Abstract: 332,293. Tugwood, R. J., (Rosenberg & Co., E.). July 5, 1929. Right to Patent relinquished. Splicing.-Relates to a device for splicing cables, particularly telephone &c. cables, which can be positively adjusted longitudinally and transversely of the cable ends, and in which the simultaneous twisting of several wires can be effected. The base plate 25 of the splicing apparatus, and the frame 34 which is secured to the cable ends and upon which the plate 25 is mounted, are provided with slots 37, 35 in which locking screws 36 engage. Each twisting hook 77, Fig. 15, is preferably formed in two parts, between which is provided a spring- controlled stripper member 113 which ejects the twisted wires upon the return movement of the hook 77. Shears 88, 89, one to each twisting hook are actuated with the hooks to cut off the ends of the wires; the hooks and shears are rotated by the movement of a rack 68, Fig. 13, controlled by the operating lever 27, the hooks being mounted upon spindles carrying pinions 73, 74 driven from the rack, and each of the shears having a projecting member engaging a slot in a sliding rod also actuated by the lever 27. Before the wire ends 50, 61 are placed in the twisting hooks, insulating sleeves 49 are slipped over the wires 50 of one cable end; upon return of the lever 27 a slide 51 carrying a support 52 pushes the insulating sleeves over the twisted wires.

Divided out of and addition to 443,784 under which a Specification was laid open to inspection under Sect 91 of the Acts, Sept. 30, 1935. [Class 103 (i)] Brake mechanism for trailer vehicles wherein the brakes are applied by the thrust-pressure or overrun of the trailer when the towing vehicle is retarded and in which a non-fluid shockabsorber is provided for ensuring smooth operation of the brakes as described in the parent Specification is adapted for two-wheeled vehicles. The draw-bar 1 is connected by a link 3 and a lever 4 to an extension 2 of the undercarriage, the lever 4 being connected by a cable 19 to the brakes. The shock-absorber comprises a damper-bar 8 attached to the drawbar and slidable between spring-pressed jaws 9 adjustable by nuts 10, the lower jaw being attached at 14 to the extension 2 or to the axle. The brake may also be applied by hand by a lever 22 mounted on the pivot 13 of the lever 4 but offset from that lever as shown in Fig. 4 and having a lateral extension 23 for engagement with that lever. The lever moves between a bracket 20 and a ratchet 18 with which a locking pawl 27 engages. To prevent application of the brakes as during reverse movement of the vehicle, an arm 15 of the link 3 has a hole through which an L-shaped pin 26 can be inserted for engaging the extension 2. Accidental disengagement of the pin is prevented by a projection thereon which is passed through an extension 25 of the hole 24. The brakes may be operated from the driver's cab by a cable attached to the cable 19.

Title: Improvements in or relating to Lasting Machines.
IPC: A43D75/00
Filed: 1917-10-16
Abstract: 122,110. British United Shoe Machinery Co., (United Shoe Machinery Co.). Oct. 16, Lasting. - Relates to fastenersupply mechanism for step by-step lasting.machines such as of the type described in Specification 14453/97, and comprises means whereby an adjustment made prior to. a particular machine cycle to influence the operation of the fastenersupply mechanism shall be effective to secure the desired result in that cycle. With the arrangement to be described the necessity for allowing the machine to perform an idle cycle of operations, following a change of tack supply, is avoided, and, moreover, no tack will be expelled by the driver unless the work ha.s been presented to the machine. An horizontal lever 2, Figs. 4 and 7, is pivoted at 4 to a lever 5, itself pivoted at 6 to the usual tack-block-actuating slide 3. The rear end of the lover 2 is connected by a link 8 to a crank rigid with a support 36 clamped to a rotary shaft 38 and 'adapted to be turned by a control lever 10, which is pivoted on lugs offset from the axis of rotation of the support. This control lever, which is coupled by. a rod 11 to to the usual raceway-shifting mechanism, carries spring-pressed arms 40, 42, Fig. 6, which during adjustment ride over a fixed curved surface 44 and one or other then snaps into an appropriate notch. A spring blade 7, Fig. 4, secured to the slide 3 engages a roll on an extension 9 of the lever 5 and holds the lever so that one or other of two tack pockets 2<x>, 2<xx>, Figs. 4 and 7, in the lever 2 will be in tack-receiving relationship to the usual separator on the normal stopping of the machine: when the machine is stopped, one tack pocket always contains a tack of the kind in one of the raceways, and the other pocket a tack of the kind in the other raceway. On the presentation of a shoe to the machine it is pressed against a foot supported by a parallellink connexion from the machine frame, and an extension 34 of the upper linl: of the connexion swings a bell-crank 14 to bring a tappet 18 in the path of a shoulder 20 on the lever 5. During the forward movement of the slide 3, the lever 5 is therefore swung to give to the tack pocket in the lever 2 a movement as indicated in dotted lines, Fig. 4, into a position of alinement with the tack driver and the passage 13 in the advancing tack block 90. This movement of the lever 5 also moves a cammed extension 24 of the lever into position to be effective to bring about the separation and delivery of a fresh tack to the emptied pocket as the machine cycle terminates. Movement of the lever 14 is prevented by the engagement of a block 10<x> on the support 36 with an extension 28 of the lever unless the control lever 10 has been moved into one or other of its settings referred to above.

Title: Method of and apparatus for burning fuel
IPC: F23C1/00
Filed: 1974-02-25
Abstract: 1445795 Gas and oil burners MITSUBISHI JUKOGYO KK 25 Feb 1974 [24 Feb 1973] 8437/74 Heading F4T A method of burning fuel to provide low concentrations of nitrogen oxide in the combustion gases, e.g. in boilers, furnaces and gas turbines, comprises mixing a first portion of the fuel with more air than is necessary for complete combustion and discharging the resulting lean mixture from at least one burner nozzle, mixing a second portion of the fuel with less air than is neccessary for complete combustion and discharging the resulting rich mixture from at least one further burner nozzle, and burning the two mixtures together. The fuel may be gaseous or light or heavy liquid fuel. The mixtures may also include an inert gas or liquid or recycled combustion products. Apparatus for carrying out the method comprises several burners (1), Figs. 4 and 5 (not shown), located adjacent one another and each comprising a central fuel supply duct (2a or 2b) and a surrounding air supply duct (3) discharging to a mixing chamber (4). The fuel supply rates are different for adjacent burners so that rich and lean mixtures are discharged through the adjacent nozzles to a common combustion zone. The burner nozzles have flame stabilizing baffles (5). Inert liquid, e.g. water, may be sprayed into each mixing chamber via respective spray nozzles (6<SP>1</SP>), Figs. 11 and 12 (not shown). A burner for heavy liquid fuel has a preliminary burning section 1<SP>11</SP>, Fig. 13, for atomizing and partially burning the heavy liquid fuel to form a gaseous fuel 14<SP>11</SP>, the section comprising a mixing chamber 21<SP>11</SP>, water vapour and heavy oil supply lines 8<SP>11</SP>, 9<SP>11</SP> and auxiliary gaseous fuel and air lines 5<SP>11</SP>, 6<SP>11</SP>; a cooling section comprising a tubular portion perforated at 13<SP>11</SP> for delivery of recycled combustion gas 11<SP>11</SP> into the hot gaseous fuel 14<SP>11</SP>; and a mixing section wherein air 12<SP>11</SP> is delivered through perforations 15<SP>11</SP> in plates 311, Figs. 13 and 14, to mix with the gaseous fuel flowing through passages 16<SP>11</SP> to combustion zone 23<SP>11</SP>. The number and/or size of the air-supply perforations 15<SP>11</SP> supplying each adjacent gaseous fuel passage 1611 is different so that the method of the invention can be achieved in a single burner. The plates 3<SP>11</SP> impart swirl to the air-fuel mixture to enhance mxing and stabilize the flame from a starting oil burner 17<SP>11</SP>. The cooling section may be omitted and instead water is injected into the hot gaseous fuel via nozzle (25<SP>11</SP>), Fig. 16 (not shown).
