Abstract: 1276660 Low-sulphur lime ESSO RESEARCH & ENG CO 5 Sept 1969 [9 Oct 1968] 47895/68 Heading C1A A process for the production of a low-sulphur lime comprises burning limestone or limestonecontaining material with a low-sulphur fuel gas derived from partial combustion of a high sulphur hydrocarbon or carbonaceous fuel in a gasifier containing a sulphur-reactive material which reacts with the sulphur compounds in the fuel. A preferred form of the gasifier consists of a fluid bed of oxides or carbonates of calcium or magnesium of particle size of 0À5 to 2 mm. The fuel, which may be a hydrocarbon fuel oil or coal, is suitably gasified by burning with 25-60% of the oxygen required for complete combustion. The oxides or carbonates react with the sulphur content of the fuel to form solid sulphur compounds which may be removed continuously or intermittently and replaced by fresh solid material. The bed temperature may be maintained at the desired temperature (800- 950 C.) by controlling the relative flow of solid material and fuel gas. The solid sulphur compounds from the gasifier may be regenerated to yield the oxide and SO 2  (some of which may be reduced to H 2 S for reaction with SO 2  to give sulphur), the oxide being returned to the gasifier for re-use.

Abstract: 1456504 Treating metal machine parts; grinding LAYSTALL ENG CO Ltd 25 Oct 1973 [25 Oct 1972] 49150/72 Headings B3D and B3A [Also in Divisions F1 and F2] A process for treating a surface of a metal machine part, such as a rubbing or bearing surface on a piston or cylinder, comprises deliberately impregnating the surface with particles of hard grit forced into the surface so as to become permanently embedded therein. The impregnation may be effected by applying pressure with a spring-loaded roller or other resiliently loaded tool. The surface, in the case of a cylinder liner, may be formed with oil-retaining grooves as a separate operation or simultaneously with the impregnating. In one example of treating a cylinder liner 10, Fig. 1, the liner is mounted so as to be engaged by the spring- loaded blades of a lapping tool which is simultaneously rotated and reciprocated while a slurry containing hard particles of grit, such as silicon carbide, is poured into the cylinder and cuts helical grooves 11 of opposite hand in the surface of the liner. Initially a light pressure of 10 p.s.i. or less without particle embedment is used followed by an increase in pressure to cause embedding of the particles 12. The grit size is 220 and the grooves have a width and depth of 0À001 mm. to 0À003 mm. The tool may be rotated at 170 r.p.m. and reciprocated five times per minute. A second operation using a grit size of 400-500 may follow to smooth the peaks off the grooves and embedded particles. In an embodiment for treating the surface of a piston P, Fig. 4, the piston is mounted on a rotary member 13 and is engaged by blades 14a which are spring pressed radially inwards towards the surface and axially into engagement with a swash plate 16. For treating an internal cylinder surface, the blades are spring pressed radially outwardly. The silicon carbide grit may be supplied in a liquid suspension or as a paste. Reference has been directed by the Comptroller to Specifications 992,743 and 1,372,171.

Abstract: 1503217 Printing machine control ROLAND OFFSETMASCHINENFABRIK FABER & SCHLEICHER AG GRAPHO METRONIC GmbH & CO 3 Dec 1975 [3 Dec 1974] 46977/75 Heading B6C [Also in Division G3] A rotary offset printing press has impression, offset and plate cylinders an inking system and a damping system controlled by detection of water layer thickness, including two alternative regulating devices for dampening liquid regulation, one operative during normal printing, the other being brought automatically into operation upon interruption of printing and replacing the first. The first regulating device 49 preferably controls the speed of dampening fountain roller 6 in response to water layer thickness detected at 44. When the offset cylinder is tripped, as detected by microswitch 43, device 48 is brought into operation which regulates by tripping dampening forme roller 10. The setting of the first regulating device can be stored at 51 so that upon resumption, the same control is used. The system may also break a driving connection to the inking system. Microswitch 46 detects when blanket wash device is in operation and prevents the first regulating device coming into operation. When normal operation is resumed, the system may prevent the blanket and impression cylinders from coming into contact until inking has been performed a number of times, and ink thinner sprayed at 54 on to the inking system under the control of a tackness detector. Final movement of the blanket cylinder into contact with the impression cylinder actuates microswitch 42 to throw out the second regulating device and throw in the first regulating device.

Title: Improvements in stop mechanisms for textile machines
Inventor: WARD KENNETH
IPC: D01H13/16
Filed: 1964-01-01
Abstract: Stop mechanism for a textile machine comprises a plate 11, Fig. 1, not shown, with one or more projections 12 over which a sliver &c. 10 moves, and a detector 15 that is reciprocated along the path of the sliver etc.; when the sliver &c. is moving normally it will carry the detector over the projection(s) but when it is stationary or absent, the projection(s) will arrest the detector. The detector comprises a plate 15 or a number of narrow plates side by side (to detect partial rupture of the sliver), hinged to arms 14 fast with a shaft 13 which is rocked through part of a revolution first one way and then the other. The plate has a protrusion 12 which may be a rivet head or a row or rows of such protrusions or a rib or ribs. In Fig. 7, not shown, to rock the shaft 13 and to stop the machine when the sliver &c. fails, an arm 20 is pivoted at 21 and terminates in a toothed sector 19 meshing a pinion fast on the shaft 13. A second arm 22 is pivoted at 23 to arm 20 and is connected at 25 through a spring 24 to the sector, and to a source of reciprocating motion at 27. It also carries a rotatable pin 35 coaxial with pivot 21 and resting on an operating lever 36 a switch 34 for stopping the machine. In normal working, the shaft 13 will be rocked by the arm 22 through its connection with the sector 19 through spring 24 and the pin 35 rotates on the lever 36.  If however, through the flap engaging a projection, the shaft 13 is prevented from rotating, the spring 24 will allow the arm 22 to move relatively to the arm 20, and the pin will move bodily to actuate the switch.  In Fig. 9, not shown, a toothed wheel 41 meshing a pinion 40 loose on shaft 13 is rocked by a reciprocating crank; the pinion 40 is fast with a cam 47 engaging a cam 48 fast on shaft 13 so that as pinion 40 rotates so does shaft 13.  If however movement of the latter is arrested cam 47 displaces cam 48 to actuate a switch 53.
