Title: Centrifugal governor
IPC: G05D13/10
Filed: 1958-05-19
Abstract: 831,177. Centrifugal governors. CATERPILLAR TRACTOR CO. May 19, 1958 [March 10, 1958], No. 15954/58. Class 57. A centrifugal governor for positioning the fuel control rack bar 24 of an internal combustion engine comprises flyweights 11 loaded by a spring 23, a control rod 28 connected to the rack bar, and a control lever 35 operable in one direction to preload the spring 23 and operable in the other direction to engage the rod 28 and position the rack bar. The flyweights are pivotally mounted on a carrier 12 driven through gearing 16, 17 from an engine driven shaft 18 and actuate a thrust member 22 to move an adaptor 27 secured to the rack bar against the spring 23. The control rod 28 is axially slidable in a bearing 29 and is formed at one end with a flange 46 providing a lost-motion connection with the adaptor 27 and carries at its other end an enlarged plate member 51. The control lever 35 comprises two bell-crank levers 36, 37 that are connected by a sleeve 38 secured to a shaft 39 rotatably journalled in the governor housing 30 and have tail portions 65 joined by a member 69 carrying a spring- loaded detent 71 adapted to engage a low idle stop cam surface 61 on an axially adjustable bolt 62. A manually-operable lever 41 is fixed to the shaft 39 outside the housing 30. The spring 23 is compressed between the adaptor 27 and a spring seat 32 slidably mounted on the bush 29 and under normal operating conditions the lever 35 abuts the seat 32 and rotation of the shaft 39 clockwise increases the spring preload until member 69 contacts an adjustable high idle stop member 81 screwed into the housing 30. When the lever 35 is moved counter-clockwise it first progressively releases the load on the spring 23 and then passes through slots 53 in the housing 30 to contact the plate 51 and positively move the rack bar to the engine shut-off position as indicated by broken lines at 54. During counterclockwise movement of the lever 35 the detent engages the surface 76 of cam 61 to indicate to the operator that the governor is set in low idle condition. Further such movement causes the detent 71 to pass over the high point of the cam and the detent spring 72 then urges the lever 35 to the shut-off position. The bolt 62 and member 81 are locked in their set positions by a common locking cap 83. Buffer springs 58 and 59 are provided for the adaptor 27 and plate 51 respectively.

Title: Improvements relating to honing and like tools
IPC: B24B33/08
Filed: 1946-05-20
Abstract: 613,962. Grinding and polishing. ALEXANDER MACHINERY, Ltd., G. H., and LEWIS, E. May 20, 1946, No. 15161. [Class 60] In a honing or like tool comprising a hollow body part carrying the abrasive elements, longitudinally - slidable adjusting members acting on the abrasive elements and a pair of relatively rotatable feed members, one of which is connected to the said adjusting members, the feeding means are dependent on the relative reciprocation of the hollow body part and a driving spindle, which actuates a pawl-andworm mechanism to impart intermittent rotational movements to one of the feed members. The adjusting members f are held in a feed member i, which is threaded over a further feed member j, the feed member j being supported by thrust bearings n against endwise movement relative to the body part a. Within the member j is rotatably mounted a worm o which engages a worm-wheel p formed on the body part a. On the worm spindle o is freely mounted a member q which carries a pawl r pivoted at q<SP>1</SP>. Within the feed member is mounted a relatively slidable ring s connected to the driving spindle u which is connected to the body part a by a transverse pin v having rollers w which move in slots x in the body part. In use the hone is rotated and reciprocated and during each retractive movement, whilst the spindle is moving relative to the body part, the ring s acts upon the pawl r which is moved about pivot q<SP>1</SP> until a shoulder r<SP>2</SP> on the pawl presses against and effects a frictional driving connection with the worm spindle o<SP>1</SP> and imparts to the worm o a small angular movement. By the interaction of the worm o and the worm-wheel p the feed member j is given a rotational movement, thus moving the feed member i axially and causing the adjusting members f to impart a radial feed movement to the abrasive elements c. To enable the amount of each feed movement to be adjusted, a member y in adjustable screwthread connection with the feed member is provided at its inner end with an eccentricallyarranged stop z adapted to limit the extent to which the pawl r can follow the ring s in each advance movement of the spindle u. A control member 5 connected to a lever 6 is associated with the pawl r so that when the pawl is moved by ring s to the position shown in Fig. 6 it is held against return movement until a gauging sleeve 4 mounted freely on the body part a is arrested by contact with the workpiece on the forward movement, the end of the sleeve 4 then striking against and actuating the lever 6, thus allowing the pawl r to return to its normal position. When the sleeve 4 passes into the bore of the work it no longer acts on the lever 6 and the pawl r is held clear of the ring s, no further feed movements being given to the abrasive elements.

Title: Treating sewage
IPC: C02F1/52
Filed: 1934-05-22
Abstract: To separate putrescible suspended matter from sewage, the matter is coagulated by adding a compound of a trivalent metal, such as ferric sulphate, and agitating with air during a detention period of several minutes, and flocculated by addition of lime or other alkali and further agitation with air.  The amount of coagulating agent used is such that the sewage at the completion of the coagulating treatment has a pH value not less than 5.  The flocculated matter is removed by causing the liquid to pass upward through accumulated sludge.  The separated sludge is thickened, dehydrated by means of a suction filter and then passed through rotary drying and incinerating apparatus.  Gases from the incinerating apparatus pass in contact with the material in the drying apparatus.  The ash resulting from incineration is treated with sulphuric acid to recover ferric sulphate for repeated use in the process.  Effluent from which the flocculated matter has been separated may be subjected to a base-exchange treatment, as described in Specification 410,607. U.S.A. Specification 1,886,267 also is referred to.
