Title: Improvements in or relating to latches
Inventor: ARTLETT-COE JOHN BURTON
IPC: E05B65/19
Filed: 1968-04-23
Abstract: 1,261,702. Latches. WILMOT-BREEDEN Ltd. 18 April, 1969 [23 April, 1968], No. 19008/68. Heading E2A. A vehicle bonnet latch comprises a headed keeper 4 which is guided by tube 23 to be successively engaged by safety latch 14, 10, 15 and by main latch 9, 16, 17, it being necessary to release these independently to free the bonnet. Both latch bolts are pivoted on a common pivot 12. The safety latch is withdrawn by a finger at 15. The main latch bolt is U-shaped, the lower arm 16 providing the latching surface entering hole 29 in the tube, and it may be released from inside the vehicle by a cable connected to the light 18. For safety, two springs 20, each being common to both latch-bolts 9 and 10, are provided. Because of the overlap between the parts 14 of the latch-bolt 10 and the arm 17 of the main latch-bolt, this cannot be moved to the releasing position unless the bolt 10 is in the engaging position. This provides a safety interlock.
Patent GB-1523042-A (GB)
Title: Device for use in cleaning pipelines and fittings
IPC: B08B9/04
Filed: 1976-05-10
Abstract: Collecting chambers (24 and 25) are connected in a transparent casing (20) of the apparatus opposite a multipath valve (22) and are used to accommodate a sponge (23) which can be moved in a reciprocating manner through a pipe (14) to be cleaned. Surrounded by the collecting chambers (24 and 25), the latter have assigned to them by-pass channels (28 and 29) which are connected to the multipath valve (22) so that water flowing via a water inlet (21) from the multipath valve (22) in one direction or the other is prevented from excessively compressing the sponge (23) inside the collecting chambers (24 and 25). The water fed via the water inlet (21) from the multipath valve (22) to the chamber (24 or 25) is therefore able to rinse the sponge (23) thoroughly and finally, together with the contaminants, reaches an outflow system, which is not illustrated, via the water outlet (30). <IMAGE>

Patent GB-567281-A (GB)
Title: Improvements in or relating to the manufacture of metal articles
IPC: C21D7/04
Filed: 1943-11-16
Abstract: 567,281. Altering physical structure by mechanical treatment. ROBIETTE, A. G. E. Nov. 16, 1943, No. 19131. [Class 83 (iv)] [Also in Group II] Rolling.-The surface of a steel or aluminium, copper, or nickel alloy, or other metal article, intended to be stressed in use, is heated to a predetermined depth by high frequency induction and this zone is subjected to rolling, peening, or other compressive force during cooling. This may produce surface hardening and pre-stressed compression according to the metal used. Cooling may be assisted by cooling the tools or work by moving air or water. The tools may have a highly polished surface and the operation may be carried out in an atmosphere of hydrogen, cracked ammonia, partly burnt town gas, or other protective gas. A peening effect may be produced by using rollers having hemispherical projections 1 /32" to ¢" in diameter all over their surface. A roller, pin or shaft may be passed through an inductor coil arranged in or on a tube of silica or " Pirex," Registered Trade Mark, which heats its surface to a depth of 1/16" to about 850‹ C. Immediately after passing the coil, highly-finished, slightly-skewed rollers act on the work. If the work varies in diameter, the pass may be controlled by a template or cam. For gears, pressure may be applied by running in mesh with a corresponding gear of hard material, e.g. tungsten. The method may also be used for bearing races or other circular forms or for bolts.

Title: Desulfurization of hydrocarbon oils
IPC: C01D1/04
Filed: 1961-06-06
Abstract: <PICT:0913729/III/1> Sulphur impurities, and also nitrogenous and metallic impurities, are removed from hydrocarbon streams by contacting the stream at a temperature of 350 DEG -800 DEG F. with molten potassium hydroxide containing 5-30% by weight, based on total reagent, of water.  The reagent may contain 5-50% by weight of barium hydroxide and/or barium hydroxide monohydrate.  A solutiser, defined as an oil-soluble organic compound of carbon, hydrogen and oxygen which forms alkali metal compounds, for example alcohols, phenols, alpha and beta naphthols, or isobutyric acid, may be present during the treatment in an amount of 0,1-10% by weight based on the hydrocarbon.  The spent potassium hydroxide, which contains potassium sulphide, may be regenerated by steam hydrolysis, preferably at 400 DEG -1000 DEG F.  An improved purification is obtained by partial hydrogenation of the feedstock.  The process may be applied to petroleum fractions such as fuel oil, shale oil, residua, reduced or whole crudes.  In the Figure, a 950 DEG F.+Kuwait residuum is partially hydrogenated in zone 2, the conditions being adjusted so that only partial (preferably 25-50%) hydrogenation takes place.  The oil issuing from zone 2 is treated with the potassium hydroxide reagent in zone 6, separated in zone 9, such separation being assisted if desired by the addition of a distillate fraction boiling below 700 DEG -800 DEG F., e.g. gasoline, heavy naphtha, kerosene, or heating oil, washed with water from line 23, separated in zone 24, and recovered via line 25.  The spent potassium hydroxide may be regenerated in zone 12, and heavy metal impurities having preferably been previously removed. Specification 913,730 is referred to.
