Title: Fingerpiece controlled gas lighters
IPC: F23Q2/173
Filed: 1963-07-26
Abstract: A gas-fuelled cigarette lighter provided with a fuel burner, a fuel shut-off valve and a fuel throttling device for determining the flame height has a single manual control lever 17 operating both the shut-off valve and throttling device. The lever 17 has a forked end 20 engaging a groove in the top of a plunger 10, forming the burner, which is slidably mounted in an element 9 slidable in the fuel burner body 6. The bottom end of the plunger 10 has an insert seating against a gas aperture in the bottom of element 9 to form a gas shut-off valve. The bottom of element 9 has an annular rim adapted to compress a wick 7 against a ball 8 on the bottom of the burner body 6 to form a throttling device. The top edge of element 9 is engaged by the edges of an aperture 15 in a lever 14 pivoted on lugs 13 on the body 6 and actuated by a cam surface 16 on the lever 17. The top end of the plunger 10 passes through the aperture 15. When the manual control lever 17 is depressed against a coil spring 19 the plunger 10 is lifted to enable gas to flow through the bore in the top thereof and the cam surface 16 depresses the element 9 via lever 14, thus compressing the wick 7 to reduce the flow of gas to the burner. In a modification, Figs. 3, 4 (not shown), the shut-off valve and throttling device are formed by a tapered screw 25 in a screw-threaded upper part 24 of a gasfeed tube 22. The tapered screw 25 has a square shank 26 engaged by burner 27 fast with a manual control lever 28 pivoted about the top end of tube 22. The lever 28 is sprung to project externally of the lighter in the inoperative position. A flint 32 with a spring 33 are held in a groove 31 by a sheet metal cover 36 holding a flint wheel 34. The operator's thumb rotates the flint wheel and then turns the lever 28 to increase the clearance between tube 22 and the screw 25 enabling gas to reach the burner 27. When released, the lever 28 turns to hermetically seal the gas tube 22. In Figs. 5 and 6 (not shown), two arrangements of the above screw 25 and screw thread 24 are shown. In one arrangement the thread 24 is of trapezoidal section with truncated apexes and the screw has a cylindrical outer surface and the troughs of the threads on a conical surface. In the other arrangement the screw 25 is normal with truncated thread apexes and the thread in the tube 22 has the thread apexes on a cylindrical surface and the troughs of the thread on a conical surface. The levers of both embodiments may also rotate the flint-wheel.

Title: Refuse Incinerator
IPC: F23G7/00
Filed: 1967-11-14
Abstract: A refuse incinerator having an outer refractory housing 24 and a stainless steel cylinder 23 is fed with sewage sludge under pressure through a nozzle 14, the combination of a compressed-air tube 21, motor 47 and end-plate 17 providing a rotating fan-shaped spray of sludge progressively spraying an entire circumferential zone of said cylinder 23. A tangential pipe 26 forces hot combustion gases around the steel cylinder 23 in the space 28 between the housing and the cylinder, heating said cylinder and igniting the dried sludge inside, until, in combination with preheated secondary air, the gas enters through opening 29 in the cylinder wall, to complete the combustion of the sludge. An exhaust outlet 37, connected to a cyclone, removes the combustion gases and the ash of the refuse, leaving only the oversize particles which disintegrate in the raceway formed by the annular projection 42 and the cylinder wall. The end walls of the housing are spaced apart by the length of the cylinder when cold plus the amount of thermal expansion of the cylinder when at combustion temperature, eliminating leakage of combustion gases when the cylinder is expanded. When the cylinder is cold, leakage is avoided by a spring 52 resiliently pressing the ends of the cylinder together. A pyrometer 56 can be used to record the temperature in space 28.
Patent ES-356328-A1 (ES)
Title: Registering apparatus
IPC: B41J1/48
Filed: 1968-07-20
Abstract: An electro-mechanical register in which numerical information is fed manually or automatically from say a punched tape or a computer, comprises a keyboard, Fig. 18 (not shown), which operates a combination of switches (1, 2, 4, 8) energizing a corresponding number of solenoids which determine the angular rotation in turn of a set of gears acting as a store, which rotation is transferred to print wheels for parallel visual read out. Energization of one or more solenoids 1, 2 &c., Fig. 17, on partial depression of any key moves a corresponding number of stops, e.g. 172, out of the path of sidewardly movable pins 152 of a friction driven paddle wheel 151 which advances a corresponding number of pins when a "go" solenoid 209 is energized on full depression of a key. On release of the solenoid(s) the pins are returned to the inoperative, i.e., left-hand position. Paddle wheel movement is transmitted through gears to an input gear 105 meshing in turn with each of storage gears 37 which are held from rotation in other than the meshing position by a spline on elements 106, 107. Depression of a print key (500) energizes a solenoid (66) which moves the gears into engagement with racks 13, Fig. 1, and also a solenoid (66A) which engages a machine clutch causing a forward, i.e., left-hand movement of the racks which each advance to a position corresponding to the remainder of the travel of the gears 37 to the zero position and hence print wheels 12 are also rotated correspondingly. Solenoids (66, 66A) are held energized for half a machine cycle by a cam-operated switch (560). The printing mechanism may be of known type and on completion of the left-hand movement of racks 13, a paper tape is brought against the type wheels. Subsequently the wheels are restored in zero position on spring return of the racks to their home position. Information may be entered through a remote keyboard or a local or remote punched tape, and machines may be run in parallel. Electrical signals from the switches may be transmitted to a computer also the printer may be controlled from such computer.

Title: Tubular knitted fabrics
IPC: D04B9/46
Filed: 1968-11-20
Abstract: A knitted fabric tube, e.g. an article of hose, is closed by knitting a separate constricted portion 15 while the tube 14 is held on the needles and subsequently joining the two portions with a connecting course. The closure portion may be constricted by a wrapping yarn 17, or may comprise a twisted double welt. In one method the tube is completed with a non- run portion. Thereafter alternate needles are directed to a low inactive level the intervening needles releasing their loops before knitting the closure in conjunction with instruments of a second bed 11. In an alternative method the tube loops are held at a low level on all needles while alternate ones are active in knitting the closure. After held by instruments of the second bed loops have been transferred to cylinder needles courses of non-run fabric are knitted to join the separate portions. The bulk of the closure may be reduced by knitting with a thinner yarn, or incorporating tuck or miss stitches in the centre of the closure.

Patent ES-403880-A1 (ES)
Title: Hydraulic repeating hammer
IPC: E21B1/26
Filed: 1972-06-15
Abstract: A hydraulic repeating hammer has a hydraulically actuated striking piston mounted on bushings for longitudinal movement in a cylinder. A piston ring flange about the middle of the elongated cylindrical piston body subdivides the annular space between the piston and the cylinder, which space is terminated longitudinally by the bushings, into two cavities each of which is adapted to be filled or emptied through one or more ports connected to the hydraulic system. The hydraulic system includes a pump with a storage tank on its intake side, a valve unit and lines interconnecting the pump, storage tank, valve unit and cylinder ports. The connection between the cylinder ports and the rest of the hydraulic system is preferably by flexible hose for isolation of mechanical shock generated by the striking piston. The portions of the piston on either side of the piston ring flange have different diameters, so that the hydraulic chambers have different radial dimensions and hence different rates of change of volume with respect to piston displacement. This feature makes it possible to connect the chamber with the smaller rate of change of volume continuously to the pressure side of the pump, so that only one port per chamber and two on-off valves are needed. An electronic system electromagnetically controls the operation preferably by digital logic, and provides for independent control of the stroke repetition rate, stroke length, dwell period and stroke start position. The piston may have an axial bore through which a pull rod with an end cap or flange may pass. The pull rod may be screwed on to the tool chuck in order that the hammer may be used to pull out a tool as well as to drive a tool into the work. Proximity switches in the cylinder ends are interconnected with the control system to protect the cylinder and its associated structure from unnecessary shock.
