No. 22991.—14th June, 1907.—Arnold Hare, of Auckland, New Zealand, Engineer. Improved means for automatically operating gas or other valves or electric switches at pre-determined times.

Extract from Specification.—This invention relates to means specially for attachment to gas control cocks or valves by which such cocks or valves may be automatically operated to shut off or open the supply of gas to a burner at stated pre-determined times. The means devised may, however, be employed for other analogous purposes in which valves have to be operated or in which electric switches have to be opened or closed at stated times. In describing the invention, it will be described as arranged for actuating the supply-valve of an ordinary pilot gas-burner. The invention also comprises means whereby the actuating apparatus for cutting off the gas-supply may be adjusted to operate at a later hour on succeeding nights for a period of days, thereby providing for lamps to which the appliances are fixed being turned off at a later hour each night during the week following a full moon. It also comprises mechanism by means of which the actuating apparatus may be prevented from turning on the gas-supply upon one day of each week, thus providing for the use of the appliance upon gas-lamps that do not require ignition on such day, as is the case with the front lamps of shops, &c., on Sundays.

No. 23004.—18th June, 1907.—Benjamin Locking, of Tennyson Street, Napier, Hawke’s Bay, New Zealand, Medical Practitioner. An improved gas-generator.

Claims.—(1.) For the purpose indicated, a combustion-chamber contained within a boiler, and means for introducing combustible material and air to the said chamber, substantially as set forth. (2.) For the purpose indicated, in combination, a combustion-chamber, a boiler containing the chamber, a gas-tube from the chamber and through the top of the boiler and an air-tube leading through the boiler to the combustion-chamber, and a fan for inducing a current of air through the air-tube, substantially as set forth. (3.) In apparatus claimed in claim 2, the employment of a steam-jet introduced into an elbow of the gas-tube, substantially as set forth. (4.) In apparatus claimed in claim 2, the employment of a water-cylinder around the gas-tube for making a gas-tight joint, substantially as set forth. (5.) In apparatus claimed in claim 2, the employment of a water-cylinder around the gas-tube, and a pipe with a stop-cock leading from the cylinder to the boiler, substantially as set forth. (6.) In apparatus claimed in claim 1, the employment of a gas-tube having a coiled part within the boiler and a tube for introducing combustible material to the chamber, and means for making a gas-tight joint at the top of said tube, substantially as set forth. (7.) The combination and arrangement of parts comprising the improved gas-generator, substantially as and for the purposes set forth and illustrated.

Claims.—(1.) In the manufacture of lime-sand bricks or blocks for building purposes, an apparatus comprising in combination a lime-treating part in which the caustic non-hydrated lime is moistened by water and then discharged over a screen, and the fine screened lime resulting therefrom is fed to a screen-refined machine such as referred to, and this refined lime is then transmitted to a mixing-machine, as 13, where it is admixed with the sand in the proportions such as specified, and water is added to it to make it in a semi-dry plastic state, and subsequently is moulded and pressed in a press, 16, and hardened by steam at high pressure.
