SPACKMAN ENGINEERING COMPANY, of 42 North 16th Street, Philadelphia, United States of America, a New Jersey Corporation (assignee of Henry Spencer Spackman, of 105 Ardmore Avenue, Ardmore, Pennsylvania, United States of America, Engineer, and Ellis Warren Lazell, of 3306 Arch Street, Philadelphia aforesaid, Engineer. Preparation of plastic compositions and accelerators therefor.

Claims.—(1.) The process of preparing plastic or cementitious material comprising lime or the like, characterized by the fact that separately prepared hydraulic calcium-aluminate rich in alumina or similar accelerating material is incorporated with the plastic or cementitious material to increase its strength and quickness of set. (2.) The process according to claim 1, characterized by the fact that plaster-of-paris or other controlling material is incorporated with the plastic and accelerating material. (3.) The process of preparing wall-plaster and similar compositions according to claim 1, characterized by the fact that a small proportion of the previously prepared accelerating material is incorporated with the lime or lime-bearing plaster material. (4.) The process of producing wall-plaster or similar compositions according to claims 1 and 3, characterized by the fact that the accelerating material is incorporated with finely divided slacked lime and calcium-sulphate or other controlling material. (5.) The process of preparing wall-plaster or similar compositions according to claims 1 and 3, characterized by the fact that puzzolanic material is incorporated with the other materials to increase the strength of the plastic composition. (6.) The process of preparing wall-plaster or similar compositions according to claims 1, 3, 4, and 5, characterized by the fact that approximately ten parts of calcium-aluminate accelerating material, formed by combining as by calcination lime or lime-bearing material and bauxite or other alumina-bearing material so that the calcium-aluminate contains approximately 40 per cent. of alumina, two parts of plaster-of-paris, and two parts of infusorial earth or silicious material, are substantially uniformly incorporated with eighty-six parts or so of slacked lime.

(Specification, 3s.)

No. 24897.—8th September, 1908.—WESTCOTE RAYMOND LYTTLETON, of Rakaia, New Zealand, Farmer. An improved apparatus for turning the leaves of music and the like.*

Claims.—(1.) Apparatus of the class described, comprising superposed pivoted arms having integral discs with gaps, a projection upon the under side of each of said arms, a pivoted driver having a toe-piece adapted to pass through the gaps, slide around the discs, and engage the projections of each of the arms in succession, and means for operating the driver, substantially as set forth.

[NOTE.—Here follow seven other claims.]

No. 24934.—17th September, 1908.—FRANK SHUMAN, of 3400 Disston Street, Tacony, Philadelphia, Pennsylvania, United States of America, Mechanical Engineer. Improvements in utilising solar heat and in apparatus therefor.

Claims.—(1.) A process for the utilisation of the heat of solar rays, characterized by the following essential features: (a) The absorption of the heat in a heat-absorbing liquid of relatively high boiling-point, exposed during its motion to the solar rays in a thin, substantially horizontal stream under a glass roof or roofs; (b) the protection of such moving fluid from ready loss of heat by radiation by stopping the circulation of the air above the moving fluid, so that the temperature of the air above successively hotter portions of the liquid is maintained successively hotter; and (c) the conversion of the heat energy of such heated liquid into mechanical work by any suitable apparatus.

[NOTE.—Here follow five other claims.]

(Specification, 10s. 6d.; drawing, 2s.)

No. 25091.—17th October, 1908.—CATHERINE THOMSON, CATHERINE E. THOMSON, CHRISTIEANN THOMSON, and MABEL THOMSON, all of Gap Road, Winton, New Zealand, Gentlewomen. Improvement in hair-pins.

[NOTE.—Here follow four other claims.]

(Specification, 2s.; drawing, 1s.)

No. 25229.—18th November, 1908.—JAMES THOMAS HUNTER, of Queen’s Chambers, Wellington, New Zealand, Patent Agent (nominee of Linotype and Machinery, Limited, of 188 and 189 Fleet Street, London, England—the assignees of Herbert Pearce and John Ernest Billington, both of Linotype and Machinery Works, Broadheath, Chester, England, Engineers). Improvements in typographical composing-machines.

Claims.—(1.) In a typographical composing-machine of the type stated, the combination with two adjacent magazines of hook-and-lug devices for holding them engaged, and manual means for disengaging the upper one from the one beneath it. (2.) In a typographical composing-machine of the type stated, the combination of magazine-frame capable of being tilted on the main frame of the machine, front-to-rear groove or grooves and transverse grooves in the magazine-frame, bottom magazine having corresponding bars and offsets to engage in the said grooves respectively, brackets upstanding from the magazine-frame by the sides of all the upper magazines, and set-screws working transversely in the sides of the latter and bearing against the internal faces of the respective brackets. (3.) In a typographical composing-machine of the type stated, the combination with the top plate of each magazine of a strip along its rear and both its side edges; shortened transverse bars and a transverse bar on the bottom plate of each upper magazine, the last-mentioned bar holding a lug projecting beyond each side of each said magazine; and an interval having an incline as 84 in each side strip. (4.) In a typographical composing-machine of the type stated, and having its distributing-mechanism fixed and magazines retractable to disengage them from their escapement-mechanisms, of pivoted magazine-entrances, and means actuated by the magazine-retracting means for opening and shutting the respective magazine-entrance. (5.) The combination with two retractable magazines having suitably pivoted magazine-entrances and means for retracting both, of a quadrant turning with the retracting-means, a plate slidably pivoted and loosely connected to one magazine-entrance, a flexible connection between the said quadrant and plate, a link pivoted to the said quadrant, and a stud-and-slot connection between the link and the other magazine-entrance.
