Title: Gas burning cigarette lighter
IPC: F23Q2/28
Filed: 1969-03-22
Abstract: To maximize the length of stroke of a spring- loaded hammer 29 striking a piezo-electric element 11 to produce an ignition spark in a gasburning cigarette lighter, the hammer and a manually moved actuating member 5, by which the hammer is cocked and released, both move partially outside the confines of the lighter body as defined when in the rest position. Downward and rearward movement of the actuating member 5 pushes back the hammer 29, by means of a notch 35 in a web 15 and a pin 31, compressing spring 34. A valve supplying gas to nozzle 8 is opened by the action of nose 25 of web 15 on a lever 26. Further movement of the actuating member causes notch 35 to ride over pin 34 against the pull of spring 22, releasing the hammer to strike the element 11 and thus producing an ignition spark between an electrode 12 and the nozzle 8. In a second embodiment (Figs. 4 to 6, not shown), the piezo-electric element and electrode are housed within the actuating member, the hammer being in the region of the nozzle until it is released to strike the element. Thus wastage of space within the closed lighter is minimized.

Title: A method of producing a synthesis gas rich in carbon monoxide
IPC: C01B3/50
Filed: 1969-08-12
Abstract: In a method of producing a CO-rich gas for oxo-synthesis by steam-cracking a liquid or normally gaseous hydrocarbon over a catalyst, CO 2 is scrubbed out of the cracked gas and recycled to the cracking stage, and at least part of the CO 2 -free gas is separated into a CO and an H 2 fraction, the CO fraction being mixed either with the other part of the CO,-free gas mixture, cr with part of the H 2 fraction. Surplus H 2 is available for desulphurizing the feedstock. If the feedstock is a liquid, all the CO 2 - free gas may be subjected to the separating step, and the feedstock may be pre-cracked over a Ni/Mg silicate catalyst to produce a CH 4 - rich gas which is then cracked with the CO 2 over a Ni/alumina or Ni/aluminium silicate catalyst. The precracking is carried out at 400 to 550 C., and the main cracking at above 750 C. In one example the feedstock is natural gas.

Patent ES-456150-A1 (ES)
Title: Stone detector
IPC: G01N21/90
Filed: 1977-02-22
Abstract: An improved device for detection of stones in the sidewalls of glass containers. Stones in the sidewalls of glass containers cause stress patterns to be formed. These patterns are visible if the glass container is viewed through crossed polarizing filters due to the refraction of polarized light. A television camera and electronic analysis circuit may be substituted for the human eye. The detection capability and reliability of the system is improved if the glass container is illuminated with primarily infra-red radiation. Then, polarizing filters which polarize infra-red radiation and remove visible light are used. A filter before the television camera lens removes far infra-red radiation and allows only near infra-red radiation to be measured. This makes the device insensitive to glass color, flutes or stippling and improves the signal to noise ratio.

Title: Multiway valve distributor for water treatment plant - programmed to isolate process water lines from regenerant
IPC: B01J49/00
Filed: 1977-07-07
Abstract: Installation for treating water by passing it through a bed material which requires periodic regeneration, e.g. a water softener using a resin bed requiring brine regeneration, has a multiway distributor fitted on top of a bottle contg. the treatment bed. The distributed comprises three piston valvel which are normally held open by through flowing water being treated. One of the piston valves is on the inelt for outer treated water, A second is on the outlet for treated water and third is on a limited flow bypass which allows a proportion of untreated water to flow directly into the treated water outlet. A programmer is used to direct a pressurized supply of water simultaneously to the actuating pistons of all three valves which are thus closed. This isolates the treatment bed completely from the processed water systems while regeneration takes place via. inlets and outlet passages through the distributor. The equipment is simple, inexpensive and automatic. During regeneration, there is complete isolation of the treatment bed from the water circuit. There is no danger of contamination of process water or loss or regenerant.
