(4.) Lime-sand brick or block-making machinery, in which lime is hydrated by water and reduced to a powder for the production of lime in a fine state, the employment of a screen having a coarse mesh, such as a ½ in. mesh, disposed at an angle such as shown, whereby by means of said coarse-mesh screen a product of lime in a fine state is produced in such.
(5.) In a lime-sand brick-manufacturing apparatus, mixing caustic (non-hydrated) lime in a fine state with wet sand, then after complete mixture supplying said mixture into large travelling receptacles wherein the completion of hydration of the lime takes place in their movement from this mixer to a place of discharge, and then discharging same into a second mixer such as referred to, from which mixer the mixture is discharged in a semi-dry condition ready for pressing.
(6.) In lime-sand brick or block-making machinery, a hardening chamber-door construction wherein the door carries radial levers, as 44, fitting under a flanged ring, as 42, on the end of the chamber, said levers being supported on the door from radial sliding supports or bearings, substantially as set forth.

No. 23021.—18th June, 1907.—PINTSCH’S PATENT LIGHTING COMPANY, LIMITED, of 38 Leadenhall Street, London, England, Manufacturers (assignee of Julius Pintsch, of 72-73 Andreasstrasse, Berlin, German Empire, Engineer). Improvements in inverted incandescence gas and like lamps.

Claims.—(1.) An inverted incandescence gas or vapour lamp in which the mantle-carrier is detachably supported from the Bunsen tube, substantially as described. (2.) An inverted incandescence gas or vapour lamp in which the Bunsen tube is bodily detachable from the lamp, substantially as described. (3.) In the apparatus claimed in the preceding claim, a detachable Bunsen tube supported from the crown-plate of the lamp at one end by a plug into which the nipple is fitted and which also closes the end of the Bunsen tube, and at the other end by a spring-urged plunger, substantially as described. (4.) An inverted incandescence gas or vapour lamp in which the Bunsen tube, reflector, mantle-carrier, mantle-holder, and mantle-guard are separately detachable, substantially as described. (5.) In the apparatus claimed in the preceding claims, a mantle-holder detachably secured to its carrier or support by means of springs which prevent rotational and also vertical displacement of the holder. (6.) In the apparatus claimed in the preceding claim, spring tongues integral with the body of the carrier which press against the lugs of the mantle-holder to prevent rotational displacement thereof, and also engage over the said lugs to prevent vertical displacement, substantially as described. (7.) In the apparatus claimed in claims 5 and 6, a clamping-spring on the carrier adapted to secure the mantle-holder and also to lock the mantle-guard, substantially as described. (8.) In the apparatus claimed in claims 6 and 7, a pin on the rear face of the mantle-holder clamping-spring co-operating with a hole in the body of the mantle-guard, substantially as and for the purpose specified. (9.) In the apparatus claimed in claim 1, the means for detachably securing the mantle-carrier to the Bunsen fitting, substantially as described with reference to Fig. 6 of the drawings. (10.) An inverted incandescence gas or vapour lamp constructed substantially as described and illustrated.

No. 23023.—22nd June, 1907.—JOHN FRANCIS LIERNUR and WILLIAM PETER LIERNUR, both of Vulcan House, 56 Ludgate Hill, London, England, Sanitary Engineers. Improvements in sewerage for towns and the like.

Claims.—(1.) A system of sewerage worked by suction or exhaustion by means of a vacuum produced at the pumping-station or other convenient position, the said vacuum being applied to district reservoirs, district pipes leading thereto, house-pipes leading to said district pipes, with traps interposed between the house and district pipes, discharge-pipes between the district reservoirs and the receiving station, substantially as and for the purpose set forth, and described and illustrated by the drawings. (2.) In a system of sewerage, the automatic ventilation of old sewers, sewage-pipes, or cesspools, or any form or kind of sewage-pipes and the apparatus connected therewith, and the utilisation of the foul gases abstracted therefrom, substantially as and for the purpose set forth and described by the drawings. (3.) In a system of sewerage, the arrangement of apparatus and provision of means by which one collecting main may be adapted to serve the double purpose of a vacuum or exhaust pipe or an ordinary sewage conveying-pipe, substantially as and for the purpose set forth, and described and illustrated by the drawings. (4.) In a system of sewerage, the provision of a furnace or stove for deodorising, burning, and destroying the foul gases collected in the several sewage mains, substantially as set forth, and described and illustrated by the drawings. (5.) In a system of sewerage, the provision of self-acting safety syphons with special gratings and ball-valves and seatings, substantially as and for the purpose set forth, and described and illustrated by the drawings. (6.) In a system of sewerage, the combination of vacuum reservoirs, vacuum sewage-pipes, safety self-acting syphons and valves, deodorising furnace, stop-cocks, and valves, substantially as and for the purpose set forth, and described and illustrated by the drawings.

No. 23024.—22nd June, 1907.—NORMAN SINCLAIR MCNAB, of Waiora Road, Caulfield, Victoria, Australia, Electrical and Mechanical Engineer, and JOSEPH SELBY LINK, of Collins Street, Melbourne, Victoria aforesaid, Consulting Engineer. Improvements in time-recording registers.

Extract from Specification.—This invention belongs to that class in which clock-mechanism actuates type-wheels, which when required print the time upon a paper or other band, which is transferred in lengths as required from a feed-roll to a winding-on reel, the paper being intended to receive (through an adjustable or other aperture in the casing) signatures or markings to indicate the attendances or movements of workmen or officials, or to indicate receipts and payments of cash, or to register any other events or matters desired, the paper being either blank or ruled in predetermined manner, and having (in some cases) printing thereon suited to the entries in view. When the machine is used as a time-book substitute, the official or employee signs on the paper and then turns a handle. This winds enough of the paper on the receiving-reel to carry the signature out of sight and leave a blank for the next entry. It also actuates a plunger which presses the paper against the type-face, which prior thereto is inked by a roller or other means, as explained. The details of this invention comprise also various parts which serve other functions, the whole machine being illustrated in the drawings. Sundry modifications and additions may, however, be made, varying the construction from what is illustrated, and different features may be omitted while still retaining matter which we claim as our invention.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
