No. 28123.—21st July, 1910.—WALTER AUGUSTUS ATTENBOROUGH, of Melbourne, Victoria, Builder. Apparatus for and improvements in and relating to automatic alarm, and steering-gear, and distance and course recorders for ships.*

Extract from Specification.—My invention relates to an improved method of or means for recording upon a ship’s chart the exact route or course which a vessel is taking or has taken in its travel, and at the same time indicates upon the chart the distance which the ship has travelled. In conjunction with the above recording-apparatus I have devised a means by which, when the vessel deviates from its set course, a series of alarms or an alarm is set up by electrical connections, which calls attention to the fact, or the apparatus may be so set that should the vessel deviate from its course it will automatically work the steering-gear of the vessel so as to bring it back to the course to which it has been set. The working of the steering-gear, and the automatic ringing of the alarm, and the recording of the ship’s course and distance of travel primarily takes its initiative from the movement of a casing containing a compass or magnetic needle. Such casing is loosely mounted upon gymbols, and connected and operating, as will afterwards be fully explained, a table upon which is carried the chart.

No. 28263.—12th August, 1910.—JAMES TRELOAR, of Hamilton, New Zealand, Engineer. An improved automatic pulsator for milking-machines.*

Extract from Specification.—The object of this invention is to provide an improved apparatus for causing the pulsations (the making and breaking of a vacuum) to take place automatically in the teat-cups of milking-machines. The means to effect this object are to provide, in a pulsator of the single-cylinder type, a double-ended piston in addition to the ordinary or power piston, the double-ended piston being slidable horizontally in the cylinder and having a hole bored horizontally through its centre to allow the rod of the ordinary or power piston to work independently of the double-ended piston. On the rod of the ordinary piston are two stops, so placed that when the power-piston is nearing the end of its stroke the double-ended piston will be operated to admit vacuum or air, as the case may be, through holes bored in the sides of the cylinder. A fly-wheel is provided to give momentum. Details of the working are given in the understated description.
