Title: Improvements in cupreous powder and method of making the same
IPC: B22F9/04
Filed: 1947-05-01
Abstract: An air-stable cupreous powder comprising particles mainly a few microns in size having a core of copper and a thin protective film of cuprous oxide, for use as an anti-fouling paint pigment, is produced by subjecting unrefined wet friable cement copper or copper precipitate to a pre-drying sufficient to condition it for flash-drying, and then immediately subjecting the material simultaneously to an impacting operation and to flash-drying in an oxidizing atmosphere.  The pre-drying reduces the moisture content, preferably to substantially 18 per cent, whilst the cuprous oxide film should be of a thickness at least sufficient to be identified by X-ray diffraction, the preferred oxide content being at least 10 per cent, and up to 15 per cent.  In an example, an anti-fouling paint comprises the cupreous powder, rosin, hydrogenated methyl abietate, chlorinated rubber, diatomaceous silica and naphtha.

Title: Gear Coupling Adapted to be Engaged and Disengaged in the Stationary Position
IPC: F16D11/14
Filed: 1967-03-13
Abstract: 1,169,118. Shaft couplings. DEMAG A.G. 13 March, 1967 [17 March, 1966], No. 11734/67. Heading F2U. In order to facilitate engagement of the parts of a spline coupling, a coupling shaft has its teeth decreased in height and width at its leading end, and a coupling sleeve 1 is provided, in advance of its internally toothed portion, with a toothless centring portion having a recess housing an arcuate arm having teeth 14a-14c. The arm has limited pivotal movement about a pin 11 and is biased inwardly by a spring 12 to a position in which the teeth 14a-14c register with the gaps between the teeth 2 of the sleeve. When the coupling shaft is introduced into the sleeve, the tapered leading end is initially supported in the toothless centring portion and then on the teeth of the arm. If the shaft is so positioned that its teeth mesh with those of the arm, further inward movement of the shaft will pivot the arm outwardly and give a slight rotary movement to the shaft to ensure correct meshing of the shaft and sleeve teeth. If, however, the shaft is so positioned that the teeth on the shaft strike those on the arm, the arm is merely pivoted outwardly until the teeth can mesh.

Filed: 1941-09-18
Abstract: 550,459. Valves ; cooling valve casings. CROSS, R. C., and CROSS MANUFACTURING CO. (1938), Ltd. Sept. 18, 1941, No. 11947. [Classes 7 (ii) and 7 (vi)] In engines with rotary valves, the cylinder is carried on a pivot offset from its axis so that pressures set up in the cylinder tend to rock it about the axis, and this rocking movement is uti 1- ized to apply a sealing pr essure between the valve and its housing. Fig. 7 shows a cylinder 1 pivoted at A to the crank case 2, so that cylinder pressures tend to press the rotary valve 3 horizontally against a sliding housing 10 bearing against a fixed abutment 11. A spring 9 assists this action, and a leaf spring 12 exerts an inward pressure on the housing 10. In modifications, the housing 10 may be pivotally mounted instead of being slidable, and may bear on a fixed abutment or be connected to the crank case by a tie rod ; or a ball crank lever may be arranged between a sliding housing 10 and a fixed abutment. Fig. 6 shows another form in which the cylinder pressures tend to force a conical valve seating 13 on to a conical rotary valve 14 mounted on a shaft 15 ; and a similar arrangement is applied to a cylindrical valve. In an engine with horizontal opposed cylinders, the housings 10 of the rotary valves extend downwards into the oil sump of the crank case, so as to be cooled thereby.
